What is the function of the machine tool fixture and what is the working principle of the machine to

Its function is to clamp machined parts.

1.Positioning. Fitting the part in the correct "exact" position on the machine is defined as the degree of freedom.

2.Clamping. Resistance to cutting forces.

3.Guide the tool. For example, the drill die sleeve of the drilling fixture.

(1) Positioning of cylindrical surface outside the workpiece: three-jaw chuck, four-jaw chuck, spring chuck;

2) Workpiece positioning with inner hole: rigid mandrel, spline mandrel, elastic mandrel;

3) The workpiece is positioned with the center hole: the center and the dial;

4) The workpiece is mainly positioned in a plane: flower plate, angle iron fixture.

Summary. Hello dear, happy to answer your <>

A machine tool fixture is a clamping device commonly used in machine tool processing to clamp a workpiece or tool. The working principle of a machine tool fixture is basically to fix the workpiece or tool holder on the fixture, so that it is connected to the machine tool spindle and maintains a stable position and orientation for various machining operations. Specifically, the machine tool fixture mainly comprises a clamping mechanism, a traction mechanism and a positioning mechanism.

The main function of the clamping mechanism is to clamp the workpiece or tool, and the common clamping methods include mechanical clamping and hydraulic clamping; The traction mechanism is to pull or limit the clamped workpiece or tool along the direction of the machine tool spindle; The positioning mechanism is a support point that provides accurate positioning for the clamping object. <>

The selection of machine tool fixtures must consider factors such as the shape, material, and processing requirements of the workpiece, as well as the use conditions of the machine tool, and the load and vibration that can occur during the machining process. In addition, factors such as the rigidity, accuracy, ease of operation, and safety of the fixture need to be considered.

What is the basis for the design of the machine tool fixture.

Hello dear, I'm glad to answer <> for you

The design basis of the machine tool fixture mainly includes the following aspects: 1Workpiece shape and size:

The design of the fixture must determine the location, number, shape and size of the embedded holding points according to the shape and size of the workpiece. 2.Workpiece quality:

The design of the fixture must also consider the quality attributes of the workpiece, such as the hardness of the workpiece, surface roughness, etc., to ensure the stiffness and accuracy of the fixture. 3.Processing method:

The design of the fixture must also take into account the machining methods used, such as milling, drilling, grinding, etc., to determine the clamping and positioning of the fixture, the cutting direction, the tool size and position, etc. 4.Machine type and specifications bend core head:

The design of the fixture must be adapted to the type and specification of the machine tool used to ensure that the fixture can be matched with the spindle and feed mechanism of the machine tool, and ensure the stability of the cutting load and the workpiece. 5.Safety Requirements:

The design of the fixture must consider the safety issues of use, such as the clamping force, release force, stability of the fixture, etc., to ensure the safety of the operator.
