[0030] The top of the inner end of the clamp ring 22 is fixed with a limit ring 23, and a friction groove 24 is provided on the inner side of the clamp ring 22. A grinding groove is provided in the middle of the workbench 1, and the grinding groove connects the upper and lower parts of the workbench 1. Both clamp rings 22 are located above the grinding groove. A workpiece 6 is arranged between the two clamp rings 22, and the outer side of the base of the workpiece 6 is attached to the inner wall of the clamp ring 22, and the top of the base of the workpiece 6 is attached to the bottom of the limit ring 23.

[0031] In this embodiment, when clamping the workpiece 6, the workpiece 1 is inserted between the two clamping rings 22 through the bottom of the clamping ring 22. When inserted, the clamping ring 22 is squeezed by the workpiece 22 and moves outward, and the spring telescopic rod 28 is compressed. When the base of the workpiece is completely moved between the two clamping rings 22, the clamping ring 22 is squeezed by the reaction force of the spring, and the workpiece 16 is pre-fixed by the squeezing force of the spring. When fixing, the top of the base of the workpiece 1 is attached to the bottom of the limit ring 23 to ensure that the workpiece 1 is in a fixed position after installation. Then, the side plate 29 is driven inward by starting the first hydraulic rod 21. The workpiece 1 is fixed by squeezing the clamp ring 22 through the first hydraulic rod 21, and the stability after clamping is ensured by the friction groove 24. This fixing method can ensure that the base of the workpiece 1 can be fixed in the same position before each grinding, which is convenient for grinding and trimming of the base.

[0033] A second hydraulic rod 31 is fixedly mounted on the top of the bottom plate 4 , and an output end of the second hydraulic rod 31 is fixedly mounted on the bottom of the lifting plate 32 .

[0034] In this embodiment, after the workpiece 1 is clamped, the lifting plate 32 is driven to move upward by starting the second hydraulic rod 31, and the lifting plate 32 moves upward to drive the grinding disc 35 to move upward. After the grinding disc 35 moves to the bottom of the base of the workpiece 1, the motor 34 is started to drive the grinding disc 35 to rotate through the reducer 33. The rotation of the grinding disc 35 can grind the base of the workpiece 1. The top of the grinding disc 35 is parallel to the upper limit ring 23 and the horizontal plane. The base can be trimmed and leveled by the grinding disc 35, and the overall operation is simple, which solves the problem of needing to spend a lot of time to learn.

[0035] Working principle: When clamping the workpiece 6, the workpiece 1 is inserted between the two clamping rings 22 through the bottom of the clamping ring 22. When inserting, the clamping ring 22 is squeezed by the workpiece 22 and moves outward, and the spring telescopic rod 28 is compressed. When the workpiece base is completely moved between the two clamping rings 22, the clamping ring 22 is squeezed by the reaction force of the spring, and the workpiece 16 is pre-fixed by the squeezing force of the spring. When fixing, the top of the base of the workpiece 1 is attached to the bottom of the limit ring 23 to ensure that the workpiece 1 is in a fixed position after installation. Then, the side plate 29 is driven to move inward by starting the first hydraulic rod 21, and the spring telescopic rod 28 is completely compressed. The clamping ring 22 is squeezed by the first hydraulic rod 21 to complete the fixation of the workpiece 1, and the friction groove 24 is used to ensure the stability after clamping and fixing. This fixing method can ensure that the base of the workpiece 1 can be fixed before each grinding. In the same position, it is convenient to grind and trim the base; and the connecting block 25 can be removed from the connecting plate 26 by releasing the fixing of the bolt 27, and the clamping ring 22 can be removed after removal, and clamping rings 22 of different sizes can be replaced after removal. Clamping rings 22 of different sizes can fix workpieces 1 of different types and sizes. After the workpiece 1 is clamped, the lifting plate 32 is driven to move upward by starting the second hydraulic rod 31, and the lifting plate 32 moves upward to drive the grinding disc 35 to move upward. After the grinding disc 35 moves up to the bottom of the base of the workpiece 1, the grinding disc 35 is driven to rotate by starting the motor 34 through the reducer 33. The rotation of the grinding disc 35 can grind the base of the workpiece 1, and the top of the grinding disc 35 is parallel to the upper limit ring 23 and the horizontal plane. The base can be trimmed and leveled by the grinding disc 35, and the overall operation is simple, which solves the problem of consuming a lot of time to learn.
