Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] This specific implementation is a cylindrical part clamping tool, and its structural schematic diagram is as follows Figure 1 As shown, it includes a base 1, a lifting platform 2, a sleeve 9 and a fixed ring 6. The lifting platform 2 is movably arranged above the base 1. The sleeve 9 is arranged above the lifting platform 2. Two groups of sleeves 9 are symmetrically arranged and are cocentrically distributed and move relative to each other. The fixed rings 6 are rotatably installed on the facing surfaces of the two groups of sleeves 9. The fixed rings 6 are cocentrically distributed with the sleeve 9. The upper surface of the fixed ring 6 is fixedly connected with a fixing frame 5. The fixing frame 5 is an L-shaped structure, and the end away from the fixing ring 6 is connected to a telescopic cylinder 4. The telescopic cylinder 4 is vertically arranged, and the end away from the fixing frame 5 is connected to a driving gear plate 3;

[0024] Reference Figure 2 The fixed ring 6 corresponds to the driving tooth plate 3. A through hole 10 is formed on the outer wall of the fixed ring 6, and the driving tooth plate 3 is inserted into the through hole 10. A connecting ring 11 is fixedly sleeved on the outer wall of one end of the sleeve 9 connected to the fixed ring 6, and a tooth groove is formed on the outer circumferential surface of the connecting ring 11. The driving tooth plate 3 passes through the through hole 10 and fits with the connecting ring 11. The surface of the driving tooth plate 3 facing the connecting ring 11 has a tooth block, and the tooth block is adapted to the tooth groove. Two groups of inner clamping blocks 8 are symmetrically arranged inside the sleeve 9, and the inner clamping blocks 8 are arc-shaped structures. A screw 7 is threadedly installed on the outer wall of the sleeve 9, and the screw 7 horizontally penetrates into the sleeve 9 and is rotatably connected to the outer wall of the inner clamping block 8.

[0025] Reference Figure 3A lifting cylinder 16 is vertically installed inside the base 1, and the lifting cylinder 16 is fixedly connected to the bottom end surface of the lifting platform 2.

[0026] Reference Figure 4 The upper surface of the lifting platform 2 is horizontally provided with a moving groove 12, and an adjusting screw 13 is embedded inside the moving groove 12. Two groups of moving blocks 15 are embedded in the moving groove 12. The moving blocks 15 are threadedly connected with the adjusting screw 13. A support column 14 is vertically provided on the upper surface of the moving block 15, and the support column 14 is fixedly connected with the bottom end surface of the fixing ring 6. When the cylindrical part is clamped, the spacing between the two groups of sleeves 9 can be adjusted, and the adjusting screw 13 rotates. The adjusting screw 13 is driven by a motor, and the threads on the outer wall of the adjusting screw 13 are oppositely arranged, so the two groups of moving blocks 15 move relatively along the moving groove 12 after being subjected to force.

[0027] Working principle: When in use, the cylindrical part is inserted into the sleeve 9, and then the screw 7 is rotated. The screw 7 is inserted along the thread of the sleeve 9, driving the inner clamping block 8 to approach the cylindrical part to clamp the cylindrical part. During the processing, the cylindrical part needs to be turned. The telescopic cylinder 4 is extended and retracted to drive the driving tooth plate 3 to rise and fall vertically along the perforation 10. The driving tooth plate 3 is adapted to the tooth groove of the outer wall of the connecting ring 11. The connecting ring 11 is forced to rotate inside the fixed ring 6, and then the sleeve 9 is forced to rotate, and the cylindrical part clamped inside the sleeve 9 rotates accordingly to adjust the processing surface;

[0028] When the cylindrical part is clamped, the spacing between the two sets of sleeves 9 can be adjusted, and the screw rod 13 is rotated. The screw rod 13 is driven by a motor, and the threads on the outer wall of the screw rod 13 are oppositely arranged, so that the two sets of moving blocks 15 move relatively along the moving groove 12 after being subjected to force;

[0029] After the cylindrical part is clamped, the height of the lifting platform 2 can be adjusted according to the height of the processing equipment. The lifting cylinder 16 starts to extend and retract, driving the lifting platform 2 to adjust the height to adapt to the height of the drill and tool on the processing equipment.
