Embodiment 1

[0037] Such as Figure 1-6 As shown, a ball machine tool fixture includes a fixture positioning part 1, a fixture clamping part 2, a fixture matching part 3, and the fixture positioning part 1 includes a moving table 1-1 directly below the moving table 1-1. There are two first sliding rail grooves 1-2 fixedly, which can realize the overall lateral movement of the clamp body, and facilitate the clamping of workpieces. Two cylindrical sliding rails 1-3 are fixed directly above the moving table 1-1, which can realize The axial movement of the clamping part 2 and the clamping part 3 of the clamp facilitates the positioning of the clamp.

[0038] Further, the clamping part 2 of the clamp is in the shape of a rectangular parallelepiped, which includes a first structural block 2-1, and the bottom of the first structural block 2-1 is provided with two slide rail grooves 2-2, which can realize the clamping part 2 of the clamp. Sliding axially along the cylindrical slide rail 1-3, a cy...

Embodiment 2

[0045] The clamping method using any one of the spherical roller clamp bodies may further comprise the steps:

[0046] Step1: The two clamped surfaces of the workpiece to be processed are parallel planes, that is, the clamping plane and the clamping plane are parallel. During operation, the clamped plane and the side of the clamping part 3 of the fixture are closely fitted together. By adjusting the clamp The position of the clamping part 2 of the fixture on the cylindrical slide rail 1-3 makes the movable spherical ball 2-4 find a suitable clamping plane, and then adjust the spherical ball 2-4 by moving the sliding brake scale block 2-8 4 Lateral displacement of the movement in the cylindrical chute 2-3 until the workpiece is clamped;

[0047] Step2: Manually apply pressure on the outer surface of the sliding brake scale block 2-8, so that the four arc-shaped protrusions are pressed into the inner slots on the edge of the rectangular ladder opening 2-5, at this time, the mova...

Abstract

The invention discloses a ball machine tool fixture and a clamping method. The fixture comprises a fixture positioning part, a fixture clamping part and a fixture buckling part. By adoption of the structure, the clamping plane and the side face of the fixture buckling part are tightly attached together during operation. By adjusting the position of the fixture clamping part on sliding rails, a spherical ball can find a proper clamping plane, and then the transverse movement displacement of the spherical ball in a cylindrical taper slot can be adjusted by sliding a sliding brake ruler block until workpieces are clamped; afterwards, pressure is applied to the outer surface of the sliding brake ruler block manually so that four arc-shaped protrusions can be pressed into an inner clamping groove in the edge of a rectangular stepped opening, the axial rotation degree of freedom of the spherical ball and the degree of freedom of the spherical ball moving horizontally left and right along the cylindrical taper slot can both be limited under the tension action of an extension spring, and the effect that the workpieces can be clamped is guaranteed.

Description

technical field [0001] The invention relates to the field of machine tool fixture equipment, in particular to a ball machine tool fixture body and a clamping method. Background technique [0002] Machine tool fixtures are an important part of machine tools. During the processing process, they play a role in fixing the processing objects so that they occupy the correct position to accept the construction. Commonly used machine tool fixtures have the following deficiencies. First, the structure is complex, and the cost of design, processing and manufacturing is high; second, the operation of clamping and unloading is complicated, and specific professional technical operation requirements affect the processing efficiency; third, the fixture The design of the machine tool is usually to meet the needs of a specific machine tool, has a certain specificity, and the application range is subject to certain restrictions. Contents of the invention [0003] The technical problem to b...
