And the adjustment of the overall fixture is easy to operate and precisely adjusted to ensure that the fixture can accurately fix and position the sheet metal parts. The sheet metal of the charging pile is clamped by the two clamping mechanisms, so as to ensure that there is no relative movement during the welding process, and thus ensure the welding quality and efficiency.

[0024] Specifically, in this embodiment, the lifting mechanism 3 includes a pair of fixed frames 301. The two fixed frames 301 are symmetrically installed at the top of the bottom plate 1. Inside the rear fixed frame 301, a first screw rod 303 is rotatably installed, and at the top, a first motor 302 is fixedly installed. The output end of the first motor 302 penetrates into the inside of the fixed frame 301 and is fixedly connected to the first screw rod 303. Inside the front fixed frame 301, a first sliding rod 304 is fixedly connected. Inside both fixed frames 301, a limiting plate 305 is provided. The limiting plate 305 is rotatably connected to the first screw rod 303. The lifting mechanism 3 drives the first screw rod 303 to rotate through the first motor 302. When the first screw rod 303 rotates, it can drive the lifting plate 4 to move up and down. During the moving process, the lifting plate 4 is further guided and limited by the first sliding rod 304 to ensure that the lifting plate 4 moves along a predetermined route.

[0025] Specifically, in this embodiment, the surface of the first screw rod 303 is threadedly connected to the rear end of the lifting plate 4, and the surface of the first sliding rod 304 is slidably connected to the front end of the lifting plate 4.

The second clamping mechanism 6 drives the half gear 604 to rotate through the rotating motor 601. The rotation of the half gear 604 can drive the rack 605 to move, so that the rack 605 can drive the movable plate 602 to move on the sliding seat 401, thereby adapting to sheet metal bodies of various different sizes and clamping and positioning them.

Driven by the second motor 506, the third screw rod 507 is driven to rotate. The rotation of the third screw rod 507 drives the sleeve 508 to move. The movement of the sleeve 508 drives the clamping plate 5011 to move, so as to clamp and fix both sides of the sheet metal. By adjusting the relative distance between the clamping plates 5011 and cooperating with the driving of the third screw rod 507 and the sleeve 508, it can adapt to sheet metal bodies of various different sizes and clamp and position them. Moreover, the adjustment of the overall fixture is easy to operate and accurately adjusted to ensure that the fixture can accurately fix and position the sheet metal parts;

[0033] The second clamping mechanism 6 drives the half gear 604 to rotate through the rotating motor 601. The rotation of the half gear 604 can further drive the rack 605 to move, so that the rack 605 can drive the movable plate 602 to move on the sliding seat 401, thereby adapting to sheet metal bodies of various different sizes and clamping and positioning them.
