Multiple sets of positioning ports are provided on the outer wall of the inner tube, and each set of positioning ports is evenly distributed in a ring structure. A movable seat is provided inside the inner tube directly opposite each set of positioning ports. The outer ring surface of the movable seat protrudes to form a positioning part directly opposite the positioning port. One end of the positioning part extends through the positioning port to the outside and is mounted with a clamping plate through a torsion spring hinge. A drive mechanism for synchronously moving the movable seat is installed at one end of the inner tube.

[0006] As a preferred technical solution, the drive mechanism includes an electric push rod and a shaft. The electric push rod is installed at one end of the inner tube, and the piston rod of the electric push rod extends into the interior of the inner tube and is fixedly connected to the shaft.

[0021] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, a clamping device for polishing stainless steel pipes according to this utility model includes an inner tube 11 and a base plate 1. An electric slide table 2 is horizontally embedded on the base plate 1. A cylinder 3 is vertically mounted on the moving platform of the electric slide table 2. A fixed seat 4 is mounted on the piston rod of the cylinder 3. A load-bearing bearing 5 is installed inside the fixed seat 4. One end of the inner tube 11 is installed in the inner ring of the load-bearing bearing 5. Multiple sets of positioning ports 12 are provided on the outer wall of the inner tube 11. Each set of positioning ports 12 is evenly distributed in a ring structure. A movable seat 18 is provided inside the inner tube 11 corresponding to each set of positioning ports 12. The outer ring surface of the movable seat 18 protrudes to form a positioning part 13 corresponding to the positioning port 12. One end of the positioning part 13 extends through the positioning port 12 to the outside and is mounted with a clamping plate 15 through a torsion spring hinge 14. A drive mechanism that drives the movable seat 18 to move synchronously is installed at one end of the inner tube 11.

[0022] In this embodiment, the driving mechanism includes an electric push rod 6 and a shaft 19. The electric push rod 6 is installed at one end of the inner tube 11. The piston rod of the electric push rod 6 extends into the interior of the inner tube 11 and is fixedly connected to the shaft 19. The other end of the shaft 19 is fixedly connected to a plurality of movable seats 18.

[0023] One end of the electric actuator is equipped with a slip ring. The electric actuator is connected to the external wiring through the slip ring, which allows the electric actuator to rotate independently, thus preventing the wires from twisting.

[0024] In this embodiment, a blocking ring 9 is installed on the inner tube 11 near the fixed seat 4. The inner tube 11 is provided with a ring structure with multiple protruding teeth 10 on one side of the blocking ring 9. A gear 8 is provided on the outside of the multiple protruding teeth 10 to mesh with the protruding teeth 10. A reduction motor 7 is installed on the fixed seat 4. The rotating shaft of the reduction motor 7 is fixedly connected to the gear 8.

[0025] After the stainless steel tube to be processed is fitted onto the inner tube, a retaining ring is used to restrict the stainless steel tube, preventing it from contacting the gears and protruding teeth.

[0026] In this embodiment, a rubber layer 16 is installed on the outer side of the clamping plate 15. The outer side of the rubber layer 16 is arranged in an arc shape. The rubber layer increases the friction between the rubber layer and the stainless steel tube, and also avoids damage to the inner wall of the stainless steel tube caused by rigid compression.

[0027] In this embodiment, the inner side of the clamping plate 15 has a protruding guide portion forming an inclined structure. Multiple pressure rings 17 are installed on the outer surface of the inner tube 11. The pressure rings 17 are all located close to each set of positioning ports 12, and the outer ring surface of the pressure rings 17 is in contact with the guide portion.

[0028] In this embodiment, the outer ring surface of the pressure ring 17 is all arranged in an arc shape, so that the flow guide can open outward along the arc-shaped pressure ring.

[0029] In use, the stainless steel tube to be processed can be directly sleeved onto the inner tube. After sleeved, the electric push rod is activated, causing the piston rod of the electric push rod to retract. The movement of the piston rod drives the shaft, which in turn drives the displacement of the moving seat. The movement of the moving seat drives the positioning part, which can move along the positioning port. The positioning part can drive the torsion spring hinge and the clamping plate. The guide part on the inner side of the clamping plate will squeeze against the pressure ring, causing the clamping plate to open outward around the torsion spring hinge until the rubber layer is in close contact with the inner wall of the stainless steel tube. Multiple clamping plates can be used to position the front, middle and rear ends of the stainless steel tube at multiple points to ensure the stability of the clamping.

[0030] After the above is completed, start the reduction motor. The start of the reduction motor drives the gear, which in turn drives the inner tube through the convex teeth, causing the inner tube to rotate along the load-bearing bearing. The rotation of the inner tube synchronously drives the clamped stainless steel tube.

[0031] The electric slide table drives the cylinder, which in turn drives the fixed seat, inner tube, and stainless steel tube, allowing the rotating stainless steel tube to enter the interior of the polishing equipment, enabling rapid grinding and polishing operations while rotating.

[0032] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any changes or substitutions conceived without inventive effort should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the scope defined in the claims.
