Description

Technical Field

[0001] The utility model relates to the technical field of clamps, in particular to a mechanical parts processing clamp. Background Art

[0002] A fixture is a device used to fix the object to be processed in the mechanical manufacturing process so that it occupies the correct position for construction or inspection. It is also called a fixture. In a broad sense, any device used to quickly, conveniently and safely install the workpiece in any process can be called a fixture. During the use of existing mechanical parts processing fixtures, both sides of the parts are directly clamped, but some irregularly shaped parts cannot be clamped and fixed, which directly affects the subsequent processing flow, resulting in poor practicality and flexibility of the clamping. Utility Model Content

[0003] The purpose of the utility model is to provide a mechanical parts processing fixture to overcome the above-mentioned defects in the prior art.

[0004] According to the utility model, a mechanical parts processing fixture comprises a main box body, an upper end surface of the main box body is fixedly provided with a pneumatic telescopic rod capable of telescopic movement, the other end of the pneumatic telescopic rod is fixedly provided with a positioning frame, a threaded cavity opening forward is provided in the positioning frame, a threaded slider with opposite threads that can move towards each other is provided in the threaded cavity, a guide frame is fixedly provided on the front end surface of the threaded slider, two sets of power shafts symmetrically arranged front and back are rotatably provided on the upper end surface of the guide frame, a clamping frame is fixedly provided on the outer cylindrical surface of the power shaft, and the clamping frame and the guide frame play a clamping role.

[0005] In some embodiments, two groups of power motors are fixedly provided in the guide frame and are symmetrical in front and back, and the lower end surface of the power shaft is dynamically connected to the power motors.

[0006] In some embodiments, a threaded screw is rotatably provided between the left and right walls of the threaded cavity, the outer cylindrical surface of the threaded screw is threadably matched with the threaded slider, a threaded motor is fixedly provided in the left wall of the threaded cavity, and the left end face of the threaded screw is dynamically connected to the threaded motor.

[0007] In some embodiments, a control panel is fixedly provided on the rear end surface of the main box body, and the control panel plays a coordinating role in regulating various movements. A chassis is fixedly provided on the upper end surface of the main box body.

[0008] Compared with the prior art, the advantages of the utility model are:

[0009] 1. The utility model starts by starting a threaded motor, thereby driving the threaded screw to start rotating, and then driving the two groups of threaded sliders and the guide frame to start moving toward each other. When the left-right symmetrical guide frame contacts the parts, the front-back symmetrical power motor starts to start, thereby driving the power shaft to start rotating, and then driving the clamping frame to start swinging. At this time, the guide frame and the clamping frame begin to clamp and fix mechanical parts of different shapes and sizes, further ensuring that the parts can be positioned from multiple directions, thereby ensuring the stability during subsequent processing and ensuring the practicality of the fixture. A pneumatic telescopic rod that can telescope is provided inside, thereby ensuring that the clamping height can be adjusted in real time according to the height of the parts, thereby ensuring the flexibility of the fixture.
