The bottom plate 2 is arranged on the electric turntable 1, the support frame 3 is arranged on the bottom plate 2 near the center position, a radially movable limiting member is arranged on the support frame 3, and the movable ends of the limiting member are respectively fixedly connected to the center positions of the inner side walls of the plurality of push plates 5. The plurality of push plates 5 are arranged vertically and are arranged in a circular matrix with the axis of the electric turntable 1 as the center. The plurality of profiling plates 17 are detachably arranged on the outer side walls of the push plates 5, and the outer side walls of the profiling plates 17 are matched with the inner side walls of the cylindrical part 6 in shape. The driving assembly is arranged at the center position of the bottom plate 2 and can radially drive the push plates 5 to move; the driving assembly includes a motor 4, a threaded rod 18, a pair of moving blocks 14 and multiple pairs of connecting plates 11. The motor 4 is fixedly arranged at the center position of the bottom plate 2.

[0020] The detailed connection means are well-known techniques in the art. The following mainly introduces the working principle and process, which are as follows:
[0021] According to the specification appendix Figure 1-2It can be seen that when the utility model works, the driving assembly drives a plurality of push plates 5 to move radially inwards to a retracted state. Since the plurality of push plates 5 are vertically arranged and distributed in a circular matrix centered on the axis of the electric turntable 1, they can form a virtual cylinder as a whole, and the overall diameter becomes smaller. The cylindrical part 6 to be processed is sleeved outside the plurality of push plates 5 and is seated on the bottom plate 2. The driving assembly works again to drive the plurality of push plates 5 to move radially outwards. Here, the push plates 5 are connected to the limiting members with radial limits on the support frame 3 to ensure the stability of their radial movement. The plurality of push plates 5 moving outwards drives the profiling plates 17 on the push plates 5 to move. Since the outer side walls of the profiling plates 17 match the inner side wall shapes of the cylindrical part 6, the plurality of profiling plates 17 can tighten and fix the inner side wall of the cylindrical part 6, and the contact area is very large, ensuring that the cylindrical part 6 will not deform, being fixed stably, improving the processing accuracy, and having strong applicability.
[0022] Among them, the driving assembly includes a motor 4, a threaded rod 18, a pair of moving blocks 14 and multiple pairs of connecting plates 11. The motor 4 is fixedly arranged at the center position of the bottom plate 2. The thread directions on both sides of the center of the threaded rod 18 are opposite and the lower end is connected to the output end of the motor 4. Threaded holes 13 are formed in a pair of moving blocks 14, and they are respectively screwed to both sides of the center of the threaded rod 18 through the threaded holes 13. One ends of multiple pairs of connections are ball-hinged to the side walls of the moving blocks 14, and the other ends are ball-hinged to both sides of the center of the inner side wall of the push plate 5. The driving is stable and the movement is stable. Compared with the driving method of the air cylinder, the pipeline components are fewer, the connection of parts is simple, and it is convenient for maintenance and repair. A clamping plate 12 is arranged at the upper end of the threaded rod 18 to limit the vertical movement range of the moving block 14.
[0023] Among them, the limiting member is a telescopic rod 15. The telescopic end of the telescopic rod 15 is fixedly connected to the center position of the inner side wall of the push plate 5, and the fixed end is fixedly connected to the support frame 3, ensuring the stability of the radial movement of the push plate 5 and also ensuring the stability of the rotation of the threaded rod 18. In addition, a support ring 10 is rotatably arranged at the center position of the threaded rod 18 through a bearing 9, and the outer side wall of the support ring 10 is connected to the fixed end of the telescopic rod 15.
[0024] Among them, a pair of grooves 16 are formed on the outer side wall of the profiling plate 17. The profiling plate 17 is fixed to the push plate 5 by screws 8 at the grooves 16, and can be disassembled and replaced, so as to be applicable to cylindrical parts 6 of different sizes, and has strong applicability.
[0025] Among them, an anti-slip pad 7 is arranged on the outer side wall of the profiling plate 17 to increase the friction force with the inner side wall of the cylindrical part 6 and ensure the stability during its tightening and fixing.
[0026] In the utility model, the electric rotation can drive the bottom plate 2 and the cylindrical part 6 on the bottom plate 2 to rotate around its axis, cooperate with external processing equipment, and improve the processing efficiency of the cylindrical part 6.
