Problems solved by technology

[0004] In the above-mentioned prior art, for parts with high dimensional accuracy, when the parts are clamped by the bench vise without using other cushioning objects to wrap the parts, the force on the jaws of the bench vise is uneven at different positions. It is easy to cause the problem that the dimensional accuracy of parts is damaged. The invention provides a fixture for machining

Embodiment 1

[0019] Such as figure 1 As shown, a fixture for machining includes a bottom plate 7, a fixed block 1, a movable block 2 and a pushing device for pushing the movable block 2 to move toward the side of the fixed block 1. The bottom plate 7 is strip-shaped, and the The fixed block 1 is fixed on one end of the base plate 7, the pushing direction of the pushing device is along the length direction of the base plate 7, both sides of the base plate 7 are provided with chute 6 along the length direction of the base plate 7, and the movable card The block 2 is provided with two slide blocks that cooperate with different slide grooves 6 respectively.

[0020] Specifically, in the above structure, by arranging sliders on both sides of the movable block 2, the sliders cooperate with the chute 6, which can be realized in the process of pushing the movable block 2 to the fixed block 1 through the pushing device. , the chute 6 on both sides of the bottom plate 7 conducts wires to the movabl...

Embodiment 2

[0022] The present embodiment is further limited on the basis of embodiment 1, as figure 1 As shown, as a simple implementation form of the pusher, the pusher includes a threaded rod 4, a threaded seat 3 and a handle 5, the threaded seat 3 is fixed on the bottom plate 7, and the threaded rod 4 is threaded with the threaded seat 3 , the axial direction of the threaded rod 4 is parallel to the length direction of the bottom plate 7, the turning handle 5 is fixed on the threaded rod 4, and the movable block 2 is located between the fixed block 1 and the pushing device. In the above structure, during the rotation of the threaded rod 4 , the end of the threaded rod 4 exerts a driving force on the movable block 2 , and the rotating handle 5 is used to drive the threaded rod 4 to rotate.

[0023] As a specific implementation scheme with a loosening function, the threads on the threaded rod 4 and the threaded seat 3 are both fine threads.

[0024] In order to prevent debris from ente...

Abstract

The invention discloses a machining clamp. The machining clamp comprises a bottom plate, a fixed clamping block, a movable clamping block and a pushing device used for pushing the movable clamping block to move towards the side of the fixed clamping block. The bottom plate is in a strip shape, the fixed clamping block is fixed to one end of the bottom plate, and the pushing direction of the pushing device is in the length direction of the bottom plate. Sliding grooves in the length direction of the bottom plate are formed in the two sides of the bottom plate. The movable clamping block is provided with two sliding blocks matched with the different sliding grooves correspondingly. By means of the structure, when component clamping is finished, uniformity of stress of various points on the clamping face is facilitated.

Description

technical field [0001] The invention relates to the field of machining equipment, in particular to a jig for machining. Background technique [0002] In the process of mechanical manufacturing, the device used to fix the processing object so that it occupies the correct position to accept construction or inspection is generally called a fixture, also known as a jig. In a broad sense, any process in the process of workpiece production, inspection or maintenance, the device used to quickly, conveniently and safely install the workpiece can be called a fixture. Such as welding fixtures, inspection fixtures, assembly fixtures, machine tool fixtures, etc. [0003] In the prior art, a bench vise is a kind of universal fixture, and is an indispensable clamping device on a fitter's bench. Although the bench vise can clamp larger workpieces and provide sufficient clamping force, for parts with high dimensional accuracy, the bench vise clamp During the holding time, the different p...
