The motor 4 is used to drive the multiple clamping blocks 2 to clamp and position.

[0030] Reference Figure 1-Figure 4The output end of the motor 4 is fixedly connected to one end of the first bidirectional threaded rod 5, the first bidirectional threaded rod 5 and the second bidirectional threaded rod 6 are both rotatably connected to the inner wall of the workbench 1, the outer wall of the first bidirectional threaded rod 5 is fixedly connected with the first bevel gear 7, the internal rotatable connection of the workbench 1 is connected with a rotating rod, one end of the rotating rod is fixedly connected with the second bevel gear 8, the second bevel gear 8 is meshed with the first bevel gear 7, the outer wall of the rotating rod is fixedly connected with a driving wheel 9, the outer wall of the second bidirectional threaded rod 6 is fixedly connected with a driven wheel 10, the driven wheel 10 is connected to the driving wheel 9 by a belt, the outer walls of the first bidirectional threaded rod 5 and the second bidirectional threaded rod 6 at both ends are threadedly connected with a moving block 11, a plurality of slide grooves 12 are provided on the top of the workbench 1, each moving block 11 is slidably connected to the corresponding slide groove 12, and each moving block 11 is fixedly connected to the bottom of the corresponding clamping block 2 after passing through the corresponding slide groove 12.

[0031] The first bidirectional threaded rod 5 and the second bidirectional threaded rod 6 can be driven to rotate in opposite directions through the clamping component, so as to avoid the phenomenon that some parts are blocked and the processing progress is delayed when processing parts. The specific operation method is as follows: first, the motor 4 is driven, and the output end of the motor 4 rotates to drive the first bidirectional threaded rod 5 to rotate. The rotation of the first bidirectional threaded rod 5 will drive the corresponding two clamping blocks 2 to move in opposite directions for clamping. The rotation of the first bidirectional threaded rod 5 can drive the rotating rod to rotate in the opposite direction through the meshing of the second bevel gear 8 and the first bevel gear 7. The rotation of the rotating rod can drive the second bidirectional threaded rod 6 to rotate in the opposite direction through the driven wheel 10 and the driving wheel 9, thereby realizing the first bidirectional threaded rod 5. And the second bidirectional threaded rod 6 rotates in the opposite direction. Through the counter rotation of the first bidirectional threaded rod 5 and the second bidirectional threaded rod 6, when the corresponding two clamping blocks 2 clamp the parts, the other two clamping blocks 2 are in a distant state. After the first processing is completed, the output end of the drive motor 4 is reversed, the obstructed position of the part will be exposed, and the other two clamping blocks 2 will be fixed, thereby realizing that the position and state of the clamping blocks 2 can be flexibly adjusted according to the processing when the parts are clamped and positioned, which is convenient for multi-angle and multi-directional processing of the parts, avoiding the situation where the part position needs to be frequently adjusted or the processing is suspended due to blocked parts, and effectively improving the processing efficiency.

[0033] The fixing components can buffer the parts during the clamping process and can adapt to various irregularly shaped automotive parts. Specifically, the electric push rod 15 is driven first, and the output end of the electric push rod 15 pushes the movable plate 16 and then pushes the telescopic plate 17, thereby clamping the parts. Since the matching block 19 is made of elastic material, when the automotive parts are irregular in shape, the elastic material will adapt to various shapes without damaging the parts, thereby ensuring the stability of the clamping and increasing the friction to prevent the parts from sliding during the clamping process.
