CNC turning tool holder tool change can not change the tool normally, and it stops after less than 1

The turret motor has three opposite phases or missing phases, and the two in the turret motor line are intermodulated or checked for external power supply.

The forward control signal of the system TL+ no output is used at the outgoing end of the multimeter system, measuring +24V and TL+ two contacts, and at the same time manually changing the tool, to see if the output voltage of these two points is +24V, if the voltage does not exist, it is a system failure, and it needs to be sent to the factory for repair or replacement of related IC components.

The output of the forward rotation control signal TL+ of the system is normal, but there is an open circuit or damage to the components of the control signal, check whether the forward rotation control signal line is broken, and check whether the contact between the contacts of this circuit is good; Check for damage to DC relays or AC contactors.

There is no power supply to the turret motor.

Check whether there is an open circuit in the power supply circuit of the turret motor, whether the contacts are in good contact, and whether the strong electrical components are damaged; Check if the fuse is blowing.

The pull-up resistor is not connected.

If the input signal of the tool position is connected to the 2K pull-up resistor, if this resistor is not connected, the tool holder will not rotate on a macro scale, and the actual action will be reversed immediately after the forward rotation, so that the tool holder will seem to be immobile.

Mechanical jamming. Rotate the tool holder by hand crank, judge whether it is stuck by the degree of tightness, if so, you need to disassemble the tool holder, adjust the machinery, and add lubricating fluid.

The mechanical jamming caused by the long anti-locking time loosens the turret on the machine, and then adjusts the anti-locking time of the turret through the system parameters.

The turret motor is damaged.

Disassemble the turret motor, rotate the turret to see if the motor rotates, if not, and then make sure that the line is okay, replace the turret motor.

Water ingress into the turret motor causes a short circuit in the motor.

Dry the motor, install protection, and do a good job of insulation.

It may be: the tool holder tool change stopped in less than 1 second, and the circuit breaker of the tool holder motor in the electrical cabinet may have tripped.

Turret motor: phase loss of turret motor caused by poor circuit breaker contact, phase loss of turret motor caused by poor contactory contact, turret motor: self-short circuit, grounding.

Turret: mechanical failure, motor belt does not move.

Turn it and stop the positive and negative poles in a short circuit (24v 0v).

Mechanical reasons:The preload of the turret is too large. It is not easy to rotate when inserted into the end of the worm with a dull wrench to rotate, and it can be rotated when it is forced, but the tool holder still cannot be started after the next clamping.

When this phenomenon occurs, it can be determined that the reason why the tool holder cannot be started is that the preload is too large, and it can be eliminated by adjusting the clamping current of the tool holder motor. The internal frame is mechanically stuck. When the worm is turned from the end of the worm, it does not move in the clockwise direction, and the reason for this is mechanical jamming.

Check whether the clamping device is in the reverse ratchet groove of the reverse alignment pin, if it is, then it is necessary to re-punch the hole of the reverse ratchet and the screw rod coupling pin hole at an angle, and then check whether the spindle nut is locked, if the nut is locked, it should be readjusted, and the rotating parts are ground to death due to poor lubrication, and should be disassembled at this time, observe the actual situation, and be lubricated.

CNC lathe cutter precautions.

According to the requirements of CNC machining for tools, the general principle of selecting tool materials is to choose cemented carbide tools as much as possible. As long as the machining situation allows the selection of carbide tools, high-speed steel tools are not used.

Ceramic tools are not only used for machining various cast irons and different steel materials, but also for processing non-ferrous and non-metallic materials. With ceramic inserts, use a negative rake angle in all cases, and blunt the cutting edge if necessary to prevent the knife from chipping.

Summary. Second-hand CNC pipe thread lathes can process all kinds of inch, metric, touch threads, turn various shafts, disc parts, play the role of ordinary lathes, is an ideal machine tool for petroleum, geology, chemical and agricultural departments. However, in the actual operation process, I believe that everyone encounters the situation that the tool holder keeps rotating and does not know how to solve it, which causes unnecessary losses.

In order to solve everyone's doubts, Aijiuku will introduce the causes of its failure and the solution measures.

1. Cause of failure: The forward control signal T1 of the system has no output. Use a multimeter to measure the outgoing end of the system, measure the two contacts of 24V and TL, and change the tool manually at the same time to see if the output voltage of these two points is 24V.

2. Cause of failure: There is no power supply for the turret motor. Check whether the power supply circuit of the turret motor is open, whether the contacts are in good contact, and whether the high-voltage electrical components are damaged.

Solution: Check if the fuse is blown.

What is the reason why the CNC lathe tool holder does not stop?

Second-hand CNC pipe thread lathes can process all kinds of inch, metric, touch threads, turn various shafts, disc parts, play the role of ordinary lathes, is an ideal machine tool for petroleum, geology, chemical and agricultural departments. However, in the actual operation process, I believe that everyone encounters the situation that the tool holder keeps rotating and does not know how to solve it, which causes unnecessary losses.

There is no power supply for the turret motor. Check whether the power supply circuit of the turret motor is open, whether the contacts are in good contact, and whether the high-voltage electrical components are damaged. Workaround:

Check if the fuse is blown.

3. Cause of failure: The pull-up resistor is not connected to the 2K pull-up resistor. Workaround:

If this resistor is not connected, the tool holder will not open at the macro level, and the actual action will be forward and then reversed, making the tool holder seem to be immobile. 4. Cause of failure: damage to the motor of the tool holder.

Solution: Disassemble the turret motor, rotate the turret to see if the motor rotates. If it does not rotate, when the line is confirmed to be normal, replace the turret motor.

5. Cause of failure: The TL output of the system's forward control signal is normal, but the control signal circuit is open or the components are damaged. Workaround:

Check whether the forward rotation control signal line is open, and whether the contacts in the circuit are in good contact; Check the DC relay or AC contactor for damage. 6. Cause of failure: the machine is stuck.

Solution: Rotate the tool holder by hand to determine whether it is stuck by tightening. If so, disassemble the turret, adjust the machine and add lubricating fluid.

7. Cause of failure: The water inlet of the turret motor causes a short circuit in the motor and makes the motor dry. Workaround:

Generally, the encoder of the tooling table is broken or the data line connected to the encoder is broken, and the signal cannot be transmitted to the system, and then the data cable connected between the tooling table and the control box behind it is brokenIt is recommended that you reconnect the cable of the tooling table or try to change the encoder of the tooling table, if it is not good, the data cable connected to the tooling table and the control box behind it is broken.

The CNC lathe is composed of a CNC device, a bed, a spindle box, a tool holder feed system, a tailstock, a hydraulic system, a cooling system, a lubrication system, a chip conveyor and other parts. CNC lathes are divided into two types: vertical CNC lathes and horizontal CNC lathes.

Develop your app. The CNC tool holder is to realize the automatic exchange of tools and the transmission of rotary live tools with rotary indexing. Therefore, the technical content is high, and it has tended to specialize in development and production. Therefore, the research, development and application of CNC turret turret have attracted the attention of the CNC machine tool industry.

A typical CNC turret turret is generally composed of a power source (motor or cylinder, hydraulic motor), a mechanical transmission mechanism, a pre-indexing mechanism, a positioning mechanism, a locking mechanism, a detection device, an interface circuit, a tool mounting table (cutterhead), a driven tool holder, etc. The action cycle of the CNC turret turret is: T command (tool change instruction - cutterhead rotation - tool position detection - pre-division - precise positioning - cutterhead locking - end signal.

The knife lamp is on, but it will be stuck with the owner after a turn, what is the reason.

Glad your question, is sorting out the relevant information, wait patiently.

1. In MDI (MDA) mode, execute T0101-T0N0N respectively (depending on how many stations you are using) to see if the tool holder cannot be executed by a certain tool number. 2. In the diagnostic state, see if there is any change in the corresponding T01-T0N values. 3. Suppose we find that the tool holder does not stop rotating only when changing the No. 3 tool, first disassemble the tool holder cover, remove the No. 3 line on the hair reel and short it against the 0V, and see if the corresponding value in the system diagnosis state has changed (there is - it means that the line is normal Hall element is broken, and there is no - it means that the No. 3 contact on the hair reel is oxidized).

Here's why:

1. The power supply is not connected and the motor does not rotate. Check whether the core is in good condition, whether the power switch is well connected, and whether the switch position is correct. When measuring the capacitance with a multimeter, whether the voltage value is within the specified range can be eliminated by replacing the fuse, adjusting the switch position, and making the connected parts in good contact.

In addition, the reasons for the power failure can also be considered as the disconnection from the tool holder to the controller, the internal disconnection of the tool holder, and the failure to switch normally due to the change of the position of the brush hall element.

2. The power supply is on, and the motor is reversed, which can be determined to be the reverse phase sequence of the motor. By checking the line, the phase sequence is changed to exclude it.

Introduction:

The development trend of CNC tool holder is: with the development of CNC lathes, CNC tool holder has begun to develop in the direction of fast tool change, electro-hydraulic combination drive and servo drive. The domestic CNC tool holder is mainly electric, which is divided into two types: vertical and horizontal. There is a vertical turret.

Four and six stations are mainly used for simple CNC lathes; Horizontal turrets have.

Eighth, tenth, twelfth and other stations, can rotate in the forward and reverse directions, and the nearest tool is selected for full-function CNC lathes. In addition, the horizontal turret also has a hydraulic turret and a servo-driven turret.

Market analysis of CNC tool holders: domestic CNC lathes will develop to the middle and high-end in the future, the mid-range use of popular CNC tool holders, high-end use of power tool holders, both hydraulic tool holders, servo tool holders, vertical tool holders and other varieties, in recent years the demand can reach 10,000 50,000 units.

It may be a mechanical failure, the inside of the tool holder into the iron pin, you change the knife pay attention to listen to whether there is movement in the tool holder, listen to whether there is a slight motor rotation sound after the stand down, if there is a description is not turning, disassemble and clean and install it back, if there is no sound is the circuit problem, then check the circuit.

Like me, I dismantled the knife holder and put it back on, and it didn't take long for it to trip again, prompting an alarm, and the tool change took too long.

I'm now wondering if the knife holder line is flooded, but I can't think of what the reason isLater, I found someone to repair it, but it was really a short circuit, and the motor line of the tool change was short-circuited.

The CNC tool holder does not rotate, and the alarm indicates that the tool change time is too long.

Explain that the tool change was not completed within the specified time.

Check whether the turret motor is broken, whether there is a power supply for the forward rotation contactor that controls the turret motor, the DC relay and DC24V power supply that control the forward rotation contactor, you can give the tool change instruction, go to see the address of the tower in the ladder diagram), see if the address coil of the turret in the turret is lit (engaged), if it is lit, it is a circuit problem from the output port to the turret motor.

If it doesn't light up, it means that the conditions for the forward rotation of the knife holder are not met, and you can see which condition is not met from the ladder diagram.

It may be a mechanical failure, so let's check the circuit last.
