Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0026] Reference Figure 1-4 The utility model provides an embodiment: a high-precision mechanical pliers, including a bottom plate 1, a vertical plate 2 is installed at the back end of the bottom plate 1, a slide groove 3 is opened on the front end surface of the vertical plate 2, the bottom plate 1 is slidably connected with the vertical plate 2 through the slide groove 3, and a lifting mechanism 4 is installed inside the vertical plate 2;
[0027] The lifting mechanism 4 includes a screw rod 401, which passes through the top of the vertical plate 2 and is connected to a brake motor 402. The surface of the screw rod 401 is spirally driven with a slider 403, and the slider 403 passes through the slide groove 3 and is fixedly connected to the base plate 1. A convex plate structure is provided on both sides of the base plate 1, and counterweight blocks are provided on both sides of the back end of the vertical plate 2.
[0028] The two convex plates of the base plate 1 are connected to guide rods 5 on both sides. A first cylinder 6 is installed on the top of the base plate 1. One end of the first cylinder 6 is connected to a convex plate 7. A working plate 8 is installed on the top of the convex plate 7. The convex plate 7 is movably connected with the guide rod 5. The convex plate 7 is driven to move horizontally by starting the first cylinder 6. The convex plate 7 moves stably under the action of the guide rod 5. When the convex plate 7 moves, it drives the top working plate 8 to move to complete the clamping position adjustment.
[0029] The back end of the convex plate 7 is connected to a second guide rod 9, one end of the second guide rod 9 is connected to a translation plate 10, both sides of the translation plate 10 are fixedly connected with moving sleeves 11, the moving sleeves 11 are movably connected to the guide rod 5, the convex plate 7 drives the translation plate 10 to move synchronously through the second guide rod 9, and the moving sleeves 11 ensure the movement stability of the translation plate 10.
[0030] A second cylinder 12 is installed on the top of the translation plate 10, and one end of the second cylinder 12 passes through the inside of the working plate 8 and is installed with a clamping mechanism 13. The clamping mechanism 13 includes two clamping plates 1301, and one end of the clamping plate 1301 is fixedly connected to a push block 1302. Both sides of the push block 1302 are set as a bevel structure. A groove is opened at the bottom of the working plate 8. The working plate 8 is slidably connected to two driven blocks 1303 through the groove. The inside of the driven block 1303 is opened with a trapezoidal groove 1304 The push block 1302 is connected to the driven block 1303 through the trapezoidal groove 1304. The second cylinder 12 is started to drive the clamping plate 1301 to perform telescopic movement. The clamping plate 1301 drives the push block 1302 to move laterally. The push block 1302 is squeezed with the inclined surface of the driven block 1303 through the trapezoidal groove 1304 and the circular groove 14, thereby driving the driven block 1303 to slide in the groove at the bottom end of the working plate 8. When the driven blocks 1303 are close to each other, they drive the clamping plate 15 to move.
[0031] The two driven blocks 1303 are arranged in mirror symmetry, and circular grooves 14 are arranged on both sides of the inner part of the trapezoidal groove 1304. The push block 1302 is slidably connected to the circular groove 14.

[0033] Working principle: When in use, the brake motor 402 is started to drive the screw rod 401 to rotate, and the screw rod 401 drives the slider 403 to move vertically on its surface through the spiral transmission. The slider 403 drives the bottom plate 1 to be lifted through the slide groove 3, so as to adapt to different height usage environments. The brake characteristics of the brake motor 402 can lock and limit the screw rod 401 structure. When the screw rod 401 stops rotating, the slider 403 completes the height fixation, and the first cylinder 6 is started to drive the convex plate 7 to move horizontally at the guide rod 5. The convex plate 7 drives the translation plate 10 to move through the second guide rod 9. The translation plate 10 is movably connected to the guide rod 5 through the movable sleeves 11 on both sides, so that it can be stably moved and adjusted under the action of the two guide rods, and the second cylinder is started. 12 drives the clamping plate 1301 to perform telescopic movement, the clamping plate 1301 drives the pushing block 1302 to move horizontally, the pushing block 1302 is squeezed by the trapezoidal groove 1304 and the circular groove 14 and the inclined surface of the driven block 1303, thereby driving the driven block 1303 to slide in the groove at the bottom end of the working plate 8, and when the driven blocks 1303 are close to each other, they drive the clamping plate 15 to move, and place the working parts between the clamping plates 15. Through the external electronic control equipment, the travel state of the second cylinder 12 can be accurately controlled, and the process number of the second cylinder 12 can be conveniently calculated, so as to accurately control the clamping distance, improve the high-precision performance of the equipment, and prevent wear of the parts during the clamping process through the pad 16.
