The two fourth bevel gears 22 are respectively fixedly installed at the front ends of the two threaded rods 12. The two third bevel gears 11 are respectively meshed and connected with the corresponding fourth bevel gears 22.

[0027] Further, the movable clamping mechanism further includes two sliding plates 14, two mounting blocks 15, two second hydraulic expansion rods 16 and two second clamping plates 17. The two sliding plates 14 are respectively slidably installed on the inner walls of the two first rectangular grooves 13. The lower end of the sliding plate 14 is a rectangular slide bar, and the upper end is a rectangular plate. The sliding plate 14 is threadedly connected with the threaded rod 12. The two mounting blocks 15 are respectively fixedly installed on the upper surfaces of the two sliding plates 14. The two second hydraulic expansion rods 16 are respectively fixedly installed on the opposite surfaces of the two mounting blocks 15. The telescopic ends of the two second hydraulic expansion rods 16 slidably extend to the adjacent surfaces of the two mounting blocks 15. The two second clamping plates 17 are respectively fixedly installed on the telescopic ends of the two second hydraulic expansion rods 16.

[0028] Further, through the motor 4, the two second clamping plates 17 on the two mounting blocks 15 can be adjusted according to the distance between the first clamping plate 20 and the fixed plate 3 after clamping the blank, so that the two second clamping plates 17 can clamp the blank of the automotive parts left and right, thereby improving the working efficiency of the device, and further improving the production efficiency of the automotive parts.

[0029] Further, second rectangular grooves 18 are formed at the upper ends of the front surfaces of the two mounting blocks 15. The left, right and upper inner walls of the two second rectangular grooves 18 are all open.

[0030] Further, through the two second rectangular grooves 18 on the two mounting blocks 15, when processing the blank of the automotive parts in the shape of a long strip or a cylinder, a supporting effect can be provided for the blank, reducing the probability of accidents, and further improving the working efficiency of the device.

[0031] Further, a first hydraulic telescopic rod 19 is fixedly installed on the front surface of the fixed plate 3. The telescopic end of the first hydraulic telescopic rod 19 slides through to the rear surface of the fixed plate 3.

[0032] Working principle: When using this device, place the blank of the automotive part on the first clamping plate 20, start the first hydraulic telescopic rod 19, and make the first hydraulic telescopic rod 19 drive the first clamping plate 20 to clamp the automotive part. After clamping, start the motor 4. The output end of the motor 4 rotates, driving the first bevel gear 6 fixedly connected to its output end to start rotating. The rotation of the first bevel gear 6 drives the second bevel gear 8 meshed with it to rotate. The rotation of the second bevel gear 8 drives the rotating connecting rod 7 fixedly connected to the second bevel gear 8 to rotate. The rotating connecting rod 7 starts to drive the two third bevel gears 11 fixedly connected to its left and right ends to rotate. The two third bevel gears 11 rotate inside the second installation groove 10. The two workbenches 1 drive the two fourth bevel gears 22 meshed with them respectively to rotate. The two fourth bevel gears 22 drive the two threaded rods 12 fixedly connected to them to rotate, so that the two sliding plates 14 threadedly connected to the outer surfaces of the two threaded rods 12 move back and forth inside the corresponding first rectangular grooves 13. The mounting blocks 15 fixedly installed on the upper surfaces of the sliding plates 14 move synchronously with the movement of the sliding plates 14. The two second hydraulic telescopic rods 16 and the two second clamping plates 17 on the two mounting blocks 15 move synchronously with the mounting blocks 15, so that the two second hydraulic telescopic rods 16 and the second clamping plates 17 move back and forth. At this time, the positions of the second hydraulic telescopic rods 16 and the second clamping plates 17 can be adjusted according to the distance between the first clamping plate 20 and the fixed plate 3, so that the two second clamping plates 17 are aligned with the automotive part. After alignment, start the two second hydraulic telescopic rods 16. The telescopic ends of the two second hydraulic telescopic rods 16 approach each other, thereby driving the two second clamping plates 17 to approach each other, clamping the automotive part on the device from left and right, and further clamping and fixing the automotive part. If the blank of the automotive part is in a long strip or cylindrical shape and its length exceeds the left and right lengths of the mounting plate 2, at this time, the two mounting blocks 15 can be moved backward by the motor 4, so that the blank of the automotive part exceeding the length of the mounting plate 2 is placed on the two second rectangular grooves 18 to support the blank of the automotive part, preventing the other end of the blank of the automotive part from being damaged due to increased force when processing one end of the blank of the automotive part.
