Lathe taper adjustment headstock with rails .

First, the lathe may be unqualified when the taper leaves the factory, and there is no margin for adjustment.

2. Adjust carefully and slowly, after the meter is qualified, you should vigorously tighten the screws of the bedside box, and then check the table after tightening, until the table is qualified after tightening the screws. When playing the table, it is necessary to play the vertical plane and the horizontal plane in two directions, and the control standard is that the parallelism of the spindle axis of the headboard box within the length of 350mm is not greater than that of the carriage. (Another:.)

When inspecting, the four corners of the lathe should be adjusted to the level. ）

3. If you really don't adjust the margin after trying, it is recommended to remove the head of the bed and scrape off the outer side of the bed guide rail that matches the headbox with a shovel.

I can tune it. There are usually two top wires under the headbox.

Take the axle as an example, the front is small and the back is large, that is, the front car goes down more.

It is necessary to loosen the back of the top wire and tighten the front top wire.

Note that the premise is to loosen the large screws on the headbox first.

It's hardest to adjust when there are only a few threads left behind.

Try to adjust the anchor screws (up and down) first, and then adjust the screws on the spindle (left and right) if they have not reached the factory standard.

It's not difficult, if you're proficient, you can do it in a few minutes.

You don't need to test bar, you can just drive a bar material, measure it, and then measure it after adjustment.

Loosen the head screws, there is a herringbone guide rail under the head of the bed, and pad a thin copper sheet on both sides of the guide rail according to the taper direction.

The lathe has a taper adjustment method:

1. Check the accuracy of the measuring machine tool and correct the parallelism of the spindle axis and the guide rail of the bed.

If it is found that the four corners of the machine tool and the anchor bolts and adjustment horns in the middle of the bed are loose, the horizontal straightness of the guide rail surface and the inclination in the vertical plane will seriously exceed the standard, or even be twisted, which will not only make the outer circle of the turning taper, but also affect other precision.

In this case, the anchor bolts and horns at the four corners of the machine tool and the middle part of the bed must be adjusted, the horizontal straightness of the guide rail surface of the bed and the inclination in the vertical plane must be re-corrected to meet the requirements, and the anchor screws must be tightened.

2. Before turning, align the rear center to make it coaxial with the spindle axis.

1) When it is found that there is a taper in the workpiece, the taper value is measured first, and then the moving direction of the tailstock and the moving distance of the tailstock are determined according to the size of the taper value.

Then carry out trial cutting, re-measure the size of both ends of the workpiece, detect whether the taper is eliminated, if the size requirements of the drawing are not met, then the tailstock must be adjusted again, continue to test cutting, measurement, until the size requirements of the drawing are met.

2) We usually use the "Adjust the tailstock offset method" of the tight nail top

The diameter of both ends of the workpiece is consistent with the feed of the sliding plate, if the diameter of the +z direction is greater than the diameter size of the -z direction, the operator stands behind the tailstock, loosens the tight jack wire of the left hand, spins the tight top wire of the right hand direction, and makes the center move to the direction of the turning tool.

The magnetic gauge can be adsorbed on the guide rail surface or the slide plate, and the dial gauge contact is pressed on the sleeve side bus of the tailstock, and the amount of movement adjusted is the general diameter difference, if the diameter of the +z direction is less than the diameter of the -2 direction, the adjustment method is reversed.

3. Replace the tailstock sleeve with a new one.

If the tailstock sleeve is used for a long time, it will be seriously worn.

The lathe has a taper for turning out the workpiece, and the headstock or tailstock should be adjusted.

1. When the tailstock is not used >, the workpiece will have a taper under the two types of conditions

a) The headboard box is not correct, and all the workpieces out of the car will have a taper, so the headbox should be adjusted at this time.

b) The headbox is no problem, the workpiece has a taper when the workpiece is long and the tailstock is not used, and most of the workpieces are stressed when the workpiece eats the knife"Let the knife"Be caused by.

Solution: 1. Use a 90° pin to reduce the radial force;

2. Re-sharpen the knife and reduce the amount of feed, adjust the taper of the tailstock of the lathe, and only adjust some jobs with a relatively small taper. Or you can find the tailstock to be straightened.

Generally, the three knives are adjusted, and the workpiece size is small at the end of the bed and the head of the bed is large, indicating that the tailstock is biased towards the arms. Contrarily.

Try it, the amount of knives is very small, three knives are enough, adjust according to your needs.

I guess it's because the headstock spindle is not parallel to the large pallet rails.

The headboard box spindle is parallel to the large pallet guide rail, and there should be an adjustment screw to find it carefully, and the headboard box screw should be loosened and adjusted with the adjustment screw. Don't be in a hurry to adjust, adjust a test run to see how much worse, adjust until there is no taper. (Note that the bedside box screws should be tightened before the test drive).

2.Adjust the gap of the carriage gap.

3.There is a taper when the outer circle of the tailstock thimble car is used, that is, the tailstock is not parallel - adjust to parallel 3There are also cases where the knives wear out too quickly.

4..If it doesn't work, pull it in a big order. The lathe spindle is not parallel to the guide rail, so please ask the master to adjust it!

There will also be a small carriage to move forward as much as possible.

There is a taper there, if there is a taper with the tail on the outside of the car, it is that the tail is not correct, and the tail is debugged left and right.

Summary. How to position the length of the spindle of the inclined rail lathe, according to the Morse taper of the inner hole of the spindle, you can match a cone by yourself, and tap a thread of M12 or M16 in the center of the cone, as long as possible. Choose a screw with a longer thread, add two nuts (adjust, and tighten), screw the screw into the top of the cone, put the cone into the spindle hole and hit it tightly, and then adjust the screw according to the workpiece.

If it helps you, hope.

The spindle of the inclined rail lathe has no taper, it is a hydraulic chuck, and the pipe connecting the hydraulic system is straight and moves with clamping and loosening, but the card does not move.

The spindle of the inclined rail lathe has no taper, it is a hydraulic chuck, and the pipe connected to the hydraulic system is straight, and moves with clamping and loosening, but the cargua does not move Hello Jane Rotten pro, this is the protection measure set by the system, which can be modified in several lines of parameters. Under normal circumstances, it is possible to order potatoes without clamping. Hope it helps.

How to position. How to position your dear, spindle positioning: Usually the spindle is only for speed control, but in some special cases also need to control the position of the spindle.

For example, when the automatic tool change is carried out on the disturbance of the machining center, when the tool needs to be transferred due to the process requirements in boring machining, and when the lathe is loading the workpiece, the spindle needs to be stopped accurately at a specific position. This is what we commonly refer to as the spindle orientation function.

The spindle orientation function is that NC issues a directional command, and the spindle stops at a certain position through a one-turn signal on the position sensor on the spindle, and provides a certain holding torque to the servo motor position ring. There are many ways to realize the spindle positioning, and there are the following according to the different control methods: (1) mechanical deceleration positioning

The spindle is mechanically decelerated and positioned, which is called mechanical deceleration positioning. (2) Electrical slowdown refers to Kaisu positioning: the electrical appliances used for the spindle to achieve deceleration and positioning are called electrical deceleration positioning.

3) Magnetic induction positioning of electrical deceleration: the spindle is decelerated by electrical appliances and positioned by magnetic induction. Fun (4) electrical deceleration mechanical positioning:
