When the X-axis drive assembly is activated, the servo motor three 34 receives the control signal and begins to rotate, which drives the screw three 32 to rotate, and the rotation of the screw three 32 causes the screw nut engaged therewith to move linearly in the X-axis direction. Because the screw nut is fixedly connected with the nut seat of the supporting plate 33, the supporting plate 33 can also move along with the movement of the screw nut in the X-axis direction, so that the workbench 5 can carry out accurate position adjustment and control in the X-axis direction, the time and error of manual operation are reduced, and the machining requirement is met.

A plurality of sets of second rotating mechanisms 8 are mounted on the supporting plate 52, a work table plate 4 is mounted at the output end of each second rotating mechanism 8, and a workpiece to be machined (automobile caliper) is mounted to the work table plate 4 through a clamp (not shown). A fourth servo motor 51 is mounted on one side of the upper end face of the support plate 33, and a worm 59 is connected to an output end of the fourth servo motor 51. One end of one rotating shaft 57 is provided with a worm wheel 58 meshed with a worm 59, and one end of the other rotating shaft 57 is provided with a mounting seat 516. One side of the mounting seat 516 is fixed with a servo motor five 53, and the servo motor five 53 is in driving connection with all the rotating mechanisms two 8 through a driving component arranged on the lower end face of the supporting plate 52.
The left-right rotation of the pallet 52 on the horizontal plane can be achieved by the combination of the servo motor four 51, the worm 59 and the worm wheel one 58, thereby adjusting the overall angles of all the work tables 4. And the servo motor five 53 drives all the rotating mechanisms two 8 to synchronously rotate through the driving component, so that each working table plate 4 can rotate on the respective plane, and the design greatly improves the flexibility and efficiency of workpiece processing.
The driving part comprises a rotating rod 514 arranged on the lower end face of the supporting plate 52 through a plurality of groups of bearing seats 513, an arc-shaped through hole 56 for the rotating rod 514 to pass through is formed in the second bearing seat 55, a synchronous belt wheel 518 is arranged at the output shaft of the fifth servo motor 53 and one end of the rotating rod 514, and the two groups of synchronous belt wheels 518 are connected through a synchronous belt. The input end of each second rotating mechanism 8 is provided with a second worm wheel 82, the rod body of the rotating rod 514 is sleeved with hollow worms 511 corresponding to the second worm wheel 82 one by one, and each hollow worm 511 is meshed with the corresponding second worm wheel 82 through a clutch assembly.
The servo motor five 53 transmits the rotation power to the rotating rod 514 through the synchronous belt, and the hollow worm 511 on the rotating rod 514 transmits the rotation power to each second rotation mechanism 8 through the engagement with the second worm wheel 82. The design of the clutch assembly allows independent control of the single or multiple rotary mechanisms 8, greatly improving the operational flexibility and efficiency of the table 5.
The clutch assembly includes a cylinder 512 secured to the lower end of the carrier 52 by a mounting plate 517, with a push plate 520 secured to the push rod end of the cylinder 512. One end of the push plate 520 is sleeved on the rotating rod 514 and is abutted with one end of the hollow worm 511, and one side of the push plate 520 is provided with a guide rod 519 which movably passes through the mounting plate 517. The shaft of the rotating rod 514 is provided with baffle plates 515 which are in one-to-one correspondence with the hollow worm 511, the shaft of the rotating rod 514 is sleeved with springs 521 which are in one-to-one correspondence with the baffle plates 515, and the springs 521 are abutted between the baffle plates 515 and the hollow worm 511. The inner cavity of the hollow worm 511 is provided with an internal spline, and the rotating rod 514 is provided with an external spline 522 corresponding to the internal spline. The spline connection allows the hollow worm 511 to slide on the rotating rod 514 while maintaining their synchronicity in rotation.
The clutch assembly has a main function of controlling the engagement and disengagement between the hollow worm 511 and the worm wheel two 82 by the operation of the cylinder 512. When the push rod of the cylinder 512 is extended, the push plate 520 pushes the hollow worm 511 and moves it to a position where it engages the worm wheel two 82, and the spring 521 compresses the power. The servo motor five 53 transmits the rotation power to the rotating rod 514 through the synchronous belt, and the hollow worm 511 on the rotating rod 514 transmits the rotation power to the rotation mechanism two 8 through the engagement with the worm wheel two 82. When the push rod of the cylinder 512 is retracted, the spring 521 pushes the hollow worm 511 away from the position where it is engaged with the second worm wheel 82 (while the servo motor five 53 is reversed for a certain number of turns), so that it is separated from the second worm wheel 82, and the rotation power of the second rotation mechanism 8 is disconnected. By controlling the action of the air cylinder 512, the single or multiple second rotating mechanisms 8 are independently controlled, so that the second rotating mechanisms 8 are precisely controlled, and different processing requirements are met.
The second rotating mechanism 8 comprises a second flange seat 81, a third thrust ball bearing, a fourth thrust ball bearing, a second gland 85, a second top cover 87, a third thrust ball bearing and a fourth thrust ball bearing.

The upper half of the central shaft 83 is sleeved in the second gland 85, and the lower half is used as an input end and extends to the outer side through the second flange seat 81 to be connected with the second worm gear 82. A second cover 87 is provided for mounting the table plate 4 and is fixed to the top of the center shaft 83. The table plate 4 is attached to the upper end surface of the second cover 87, and rotates with the rotation of the center shaft 83. The second flange seat 81 is used as a supporting and positioning structure of the central shaft 83 and is fixed on the lower end surface of the supporting plate 52, and the top of the second flange seat penetrates out of a hole reserved in the supporting plate 52 to provide a channel for the central shaft 83. The second gland 85 is fastened to the top of the second flange seat 81, and is used for stabilizing the upper half of the central shaft 83. An inner retainer ring II 88 is arranged on the inner peripheral surface of the second gland 85, and an outer retainer ring II 84 is arranged on the shaft body of the upper half part of the central shaft 83. The shaft body of the upper half part of the central shaft 83 is sequentially sleeved with a third thrust ball bearing and a fourth thrust ball bearing from top to bottom, and the third thrust ball bearing and the fourth thrust ball bearing are used for supporting the central shaft 83 and bearing axial force generated in the rotating process. The third thrust ball bearing abuts between the second cap 87 and the second inner retainer 88, and the fourth thrust ball bearing abuts between the second inner retainer 88 and the second outer retainer 84. The top of the second gland 85 is fixed with a second sealing ring 86, so that metal scraps are prevented from invading into the third thrust ball bearing along the gap between the second top cover 87 and the second gland 85.
The servo motor five 53 transmits rotary power to the rotary rod 514 through a synchronous belt, the hollow worm 511 on the rotary rod 514 drives the worm wheel two 82 to rotate, and the worm wheel two 82 drives the central shaft 83 to rotate, so that the rotation of the working table plate 4 is realized. The design of the third thrust ball bearing and the fourth thrust ball bearing ensures stability and reliability of the center shaft 83 during rotation. The design enables the workpiece on the workbench plate 4 to be processed at multiple angles conveniently, and improves the working efficiency and the flexibility.
