The first movable seat 10 is connected to the horizontal drive assembly 20, and the second movable seat 30 is connected to the vertical drive assembly 40. Both the horizontal drive assembly 20 and the vertical drive assembly 40 include a drive motor and a lead screw transmission assembly, forming a lead screw transmission structure to realize the synchronous horizontal and vertical linear reciprocating motion of the pressing assembly 50 and the rotating assembly 60.
[0032] The pressing component 50 is positioned above the rotating component 60, and the workpiece is clamped between the pressing component 50 and the rotating component 60. The rotating component 60 can drive the workpiece and the pressing component 50 to rotate.
[0033] Specifically, the pressing assembly 50 includes a main drive cylinder 51, a connecting frame 52, a transfer unit, and a pressing and rotating unit. The connecting frame 52 is connected to the second movable seat 30. The main drive cylinder 51 can be a hydraulic cylinder, which is mounted on the connecting frame 52 and connected to the transfer unit. The transfer unit is rotatably connected to the pressing and rotating unit. The main drive cylinder 51 can drive the pressing and rotating unit to make lifting and lowering movements.
[0034] Furthermore, the rotating assembly 60 includes a fixed base 61, a rotating table 62, and a clamping plate 63. The fixed base 61 is connected to the second movable base 30. The rotating table 62 is mounted on the fixed base 61, and the clamping plate 63 is mounted on the rotating table 62 and rotates with the rotating table 62. The workpiece is mounted between the pressing unit and the clamping plate 63. The rotating table 62 is a conventional indexing table structure in the field, achieving precise 360° rotation.
[0035] Furthermore, the adapter unit includes an adapter 53, an upper cover 54, and an adapter seat 55. The adapter seat 55 is provided with a through hole 551.
