Embodiment 1

[0019] Such as figure 1 , figure 2 As shown, the pressure controllable worm self-locking anti-loosening fixture includes a fixture seat 1, a screw rod 2, a moving block 3, and a clamping block 4. The upper end of the fixture seat 1 is pressed on the concave edge of the lower end of the moving block 3, and the clamping block 4 The lower end is pressed on the concave edge of the upper end of the moving block 3, and the screw 2 is engaged with the moving block 3, and also includes a worm wheel 5, a worm 6, and a dial 7. The worm wheel 5 is assembled on the screw 2 through a key, and the worm 6 The rolling bearing is assembled on the fixture base 1 and meshed with the worm wheel 5 , and the dial 7 is fixed on the worm 6 .

[0020] The helix angle of the worm 6 is smaller than the equivalent friction angle of the meshing surface with the worm wheel 5 . The worm 6 is a single-head worm, and its cross-sectional tooth profile is an Archimedes spiral.

Embodiment 2

[0022] Such as figure 1 , figure 2 As shown, the pressure controllable worm self-locking anti-loosening fixture includes a fixture seat 1, a screw rod 2, a moving block 3, and a clamping block 4. The upper end of the fixture seat 1 is pressed on the concave edge of the lower end of the moving block 3, and the clamping block 4 The lower end is pressed on the concave edge of the upper end of the moving block 3, and the screw 2 is engaged with the moving block 3, and also includes a worm wheel 5, a worm 6, and a dial 7. The worm wheel 5 is assembled on the screw 2 through a key, and the worm 6 The rolling bearing is assembled on the fixture base 1 and meshed with the worm wheel 5 , and the dial 7 is fixed on the worm 6 .

[0023] The helix angle of the worm 6 is smaller than the equivalent friction angle of the meshing surface with the worm wheel 5 . The worm 6 is a double-headed worm, and its cross-sectional tooth profile is a concave arc.

Abstract

The invention discloses a pressure-controllable worm self-locking type anti-loosing fixture, and belongs to the field of fixtures. The pressure-controllable worm self-locking type anti-loosing fixture comprises a fixture base, a screw rod, a moving block, and a clamping block. The upper end of the fixture base is pressed on an emargination of the lower end of the moving block, and the lower end of the clamping block is pressed on an emargination of the upper end of the moving block. The screw rod is meshed with the moving block. The pressure-controllable worm self-locking type anti-loosing fixture further comprises a worm wheel, a worm, and a dial, wherein the worm wheel are assembled on the screw rod through a key, the worm is assembled on the fixture base through a rolling bearing and meshed with the worm wheel, the dial is fixed to the worm. The pressure-controllable worm self-locking type anti-loosing fixture solves the problems that in an existing fixture, the fixture is not reliably clamped, clamping force is not easy to control, looseness is prone to occurring, and has the advantages of being simple in structure, reasonable in design and easy to manufacture.

Description

technical field [0001] The invention belongs to the field of fixtures, and more specifically relates to a pressure-controllable worm self-locking anti-loosening fixture for preventing loose clamping of workpieces. Background technique [0002] In the machinery manufacturing industry, lathes are widely used to process various parts. When processing parts, the problem of clamping and positioning is involved. When the workpiece is being processed, it is clamped by the fixture so that it can be adapted to various cutting processes. However, due to the vibration of the machine tool and the action of the cutting force during the processing, the fixture is loose, and the workpiece is loose due to insufficient clamping force of the workpiece, which reduces the machining accuracy, and in severe cases, the workpiece will be thrown out. . At the same time, it is necessary to ensure that the clamping force of the fixture is easy to control when clamping the workpiece. Contents of th...
