The device has a simple structure and is easy to use. The cylinder 7 drives the T-shaped arm 8 to drive the fixing block 9 to position and fix the mechanical parts. Compared with the traditional manual positioning method, it not only reduces the labor intensity of the staff, but also can improve the positioning efficiency, which is convenient for the rapid processing of parts.

[0032] Also, see Figure 3 In order to reduce the damage caused by the fixing block 9 to the parts, the present application makes the following design:

[0033] The first baffles 11 are symmetrically arranged on both sides of the fixed block 9, and the end of the T-shaped arm 8 close to the fixed block 9 is also designed in an arch shape, and the second baffles 12 are symmetrically arranged on both sides of the arched end of the T-shaped arm 8. A connecting rod 13 is welded on one side of the first baffle 11, and the connecting rod 13 is slidably inserted in the second baffle 12, and the end of the connecting rod 13 passes through the second baffle 12 and connects to the limit block 14.
