[0021] The following is combined with Figure 1 - Figure 4 This application is described in further detail.

[0022] Reference Figure 1 - Figure 4 A sheet metal polishing and grinding component comprises a grinding table 1, a clamping cavity 2 is opened inside the grinding table 1, a side clamping plate 3 is slid in the clamping cavity 2, an internal threaded hole 4 is opened in the middle of the side clamping plate 3, and a bidirectional lead screw 6 threadedly matched with the internal threaded hole 4 is arranged inside the grinding table 1, a motor whose output end is connected to one end of the bidirectional lead screw 6 is fixed at the outer end of the grinding table 1, a clamping frame 8 located on the grinding table 1 is fixed on the upper surface of both ends of the side clamping plate 3, and a positioning hole 9 is opened on the clamping frame 8, a clamping rod 10 is slidably arranged inside the positioning hole 9, an upper clamping plate 11 is fixed at one end of the clamping rod 10, a cylinder 13 is fixed to the bottom center of the grinding table 1, a combination frame 14 is fixed at the output end of the cylinder 13, symmetrical sliding seats 15 are arranged at both ends of the combination frame 14, and a movable groove is opened at the connection between the side clamping plate 3 and the clamping frame 8.

[0023] Reference Figure 3 - Figure 4 A symmetrical guide hole 5 is also formed on the side clamping plate 3, and a guide rod 7 penetrating the guide hole 5 is fixed inside the clamping cavity 2. The guide hole 5 and the guide rod 7 stabilize the side clamping plate 3 to ensure the stability of the clamping component when in use.

[0024] Referring to the figures, the upper clamping plate 11 is located inside the clamping frame 8 and directly above the movable groove.

[0025] Reference Figure 3 - Figure 4 Fixed linear sleeves 16 are provided at both ends of the sliding seat 15, and a fixing rod 17 penetrating the linear sleeve 16 is fixed at the bottom of the grinding table 1. The linear sleeve 16 and the fixing rod 17 cooperate to ensure the stability of the cooperation between the sliding seat 15 and the sliding groove 12.

[0026] Reference Figure 3 - Figure 4A mounting seat 18 is slidingly provided in the movable groove between the side clamping plate 3 and the clamping frame 8, and a rotating guide wheel 19 is provided at the upper end of the mounting seat 18. A spring 20 is also provided between the bottom of the mounting seat 18 and the bottom of the movable groove. The mounting seat 18 can only move up and down inside the movable groove. The spring 20 drives the guide wheel 19 to protrude from the inner lower end of the clamping frame 8. The guide wheel 19 is convenient for taking and placing the workpiece. The spring 20 can play the adaptive role of the guide wheel 19. When clamping, the spring 20 is compressed, and the guide wheel 19 enters the inside of the side clamping plate 3 and loses its function. When not clamping, the guide wheel 19 is popped out to assist in loading and unloading.

[0027] Reference Figure 1 - Figure 4 One end of the clamping rod 10 with the sliding groove 12 passes through the bottom of the grinding table 1, and the bottom of the grinding table 1 is provided with a slot for the movement of the clamping rod 10, and the sliding groove 12 also slides in the sliding seat 15. The sliding cooperation of the slot at the bottom of the grinding table 1 for the movement of the clamping rod 10 and the sliding groove 12 in the sliding seat 15 can avoid interference between side clamping and vertical clamping, and has a good cooperation effect.

[0028] Working principle: The mounting seat 18 moves at the end of the side clamping plate 3, and the spring 20 pushes the guide wheel 19 out and protrudes on the inner bottom of the clamping frame 8. The position of the clamping frame 8 is adjusted according to the size of the workpiece to be polished. The bidirectional lead screw 6 is driven by the motor. The bidirectional lead screw 6 drives the side clamping plate 3 to move inside the clamping cavity 2 through the spiral with the internal threaded hole 4. The guide rod 7 follows and slides at the outer end of the guide hole 5. The position of the clamping frame 8 changes accordingly. The sliding groove 12 follows and slides synchronously inside the sliding seat 15 to adjust the spacing to a size close to the workpiece, but does not form a clamping force on the side. The workpiece to be polished is placed in the four clamping frames 8 through the guide wheel 19, and the motor at the end of the guide hole 5 is started again to limit the side of the workpiece.

[0029] The starting cylinder 13 drives the combined frame 14 to move downward, and the combined frame 14 drives the sliding seats 15 at both ends to move downward at the same time, the linear sleeve 16 slides downward on the outer end of the fixed rod 17, and the sliding seat 15 drives the clamping rod 10 and the upper clamping plate 11 to move downward in the positioning hole 9. At this time, the spring 20 will be compressed, the bottom of the workpiece will contact the inner bottom of the clamping frame 8, and the upper end of the workpiece will be clamped by the upper clamping plate 11.

[0030] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
