[0002] Currently, the assembly of box-type vibrators or similar products, such as the F-series box-type vibrators, internally known as "high-end vibrators," has always relied on manual assembly by workers. This process is highly unpredictable, resulting in poor assembly quality. Assembly quality and efficiency depend entirely on the experience and skill of the operators, leading to significant uncertainty. This results in high labor intensity, low production efficiency, high production costs, and poor product quality stability. These issues have long plagued the production, sales, and development of this product. In particular, the spindle clamping and feeding process has always been done manually, resulting in low efficiency and low precision. Summary of the Invention

The X-axis slide stages 12 are connected to an X-axis 13 located between the two X-axis slide rails 10. One end of the X-axis 13 is equipped with an X-axis bearing seat 14, and the other end is connected to an X-axis planetary reducer 16 via an X-axis coupling 15. The X-axis planetary reducer 16 is connected to an X-axis servo motor 17. A front and rear slide stage 18 is provided on the upper surface of the X-axis slide stage 12 near the X-axis bearing seat 14. The front and rear slide stages 18 include components parallel to each other on their upper surfaces. The Y-axis slide rails 19 are provided on two Y-axis slide rails 19, and Y-axis lead screw sliders 20 adapted to the Y-axis slide rails 19 are provided on the Y-axis lead screw sliders 20. Y-axis slide tables 21 are provided on the Y-axis lead screw sliders 20. The Y-axis slide tables 21 are connected to the Y-axis 22 located between the two Y-axis slide rails 19. One end of the Y-axis 22 is provided with a Y-axis bearing seat 23, and the other end is connected to a Y-axis planetary reducer 25 through a Y-axis coupling 24. The Y-axis planetary reducer 25 is connected to a Y-axis servo motor 26. The front end of the front and rear slide tables 18 is connected to a clamping platform. The clamping platform includes a lower fixing plate 27 for the grippers. The lower fixing plate 27 for the grippers is connected to the front and rear slide tables 18. A hydraulic cylinder fixing plate 28 is provided at one end of the slide table 18. The fixed end of the hydraulic cylinder 29 is fixed on the hydraulic cylinder fixing plate 28. The telescopic end of the hydraulic cylinder 29 is connected to the balance body 30. Two identical gripper mechanisms are provided in parallel on the balance body 30. Each gripper mechanism includes a double-sided rack 31 connected to the balance body 30. The double-sided rack 31 meshes with the hinge shafts 32 on both sides respectively.

The screw jack 6 descends, causing the left and right slides 9, the front and rear slides 18, and the clamping platform to fall together. The front and rear slides 18 extend forward under the action of the Y-axis planetary reducer 25 and the Y-axis servo motor 26 driving the Y-axis lead screw slider 20. The grippers 36 open and close under the action of the hydraulic cylinder 29 driving the double-sided rack 31, which in turn drives the gripper fixing plate 33 and the two gripper support rods 35, clamping the main shaft. The screw jack 6 rises, and the left and right slides 9 and the front and rear slides 18 move in tandem, moving the grippers 36 to the predetermined assembly position. After positioning, the screw jack 6 lowers the left and right slides 9 and the front and rear slides 18 to assemble the main shaft. After assembly, the grippers 36 release, and the left and right slides 9 and the front and rear slides 18 move in tandem, causing the clamping platform to reset.
