Description

Technical Field

[0001] The utility model relates to the technical field of metal pipe fitting production, and more specifically, to a clamping mechanism for hardware pipe fitting polishing equipment. Background Art

[0002] Automobile and machinery parts usually require pipe fittings, which are hollow metal pipes. Before being put into use, metal pipes must be ground and polished to reduce the surface roughness of the workpiece in order to obtain a bright and smooth surface.

[0003] For example, the authorization announcement number CN216633457U discloses a cutting and polishing equipment for the production of metal pipe fittings. The clamping mechanism is suitable for clamping metal pipes of different diameters. The metal pipe is rotated by the driving mechanism to facilitate the operator to grind and polish the surface of the metal pipe. The two driving trolleys simultaneously move toward the clamped metal pipe. When the two lifting mechanisms are stuck at the two side ends of the metal pipe, they stop moving. It is suitable for the change of the position of the two ends of metal pipes of different lengths. There is no need for staff to assist in lifting the metal pipe and pushing the metal pipe to move, which reduces the labor intensity of the staff.

[0004] However, during use, the outer wall of the pipe is clamped by the clamping mechanism. During grinding, the clamped position of the pipe is blocked by the clamping mechanism, and the clamped position of the pipe cannot be grinded. The only way is to manually change the key clamped position to re-grind it, which is troublesome and time-consuming. Utility Model Content

[0005] In view of the shortcomings of the prior art, the utility model aims to provide a clamping mechanism for a hardware pipe polishing device which will not block the area on the outer peripheral wall of the pipe that needs to be polished.

[0008] The moving assembly includes a fixed seat, a stepper motor and a ball screw. The fixed seat and the stepper motor are respectively placed at both ends of the slide slot, the ball screw is placed between the fixed seat and the stepper motor, the output end of the stepper motor is connected to the ball screw, and the outer peripheral wall of the ball screw is covered with a slide seat.

[0010] The positioning seat and the mounting seat are correspondingly provided with fixing pieces, the hardware pipe fitting is placed between the two fixing pieces, and the fixing piece extends into the hardware pipe fitting.

[0011] The utility model is further configured as follows: the fixing member comprises a connecting pipe and a fixing plate connected to the connecting pipe, the connecting pipe is provided with a fixing hole, the fixing plate is provided with a docking rod for extending into the fixing hole, and the docking rod is fixedly connected to the fixing plate.

[0013] The utility model is further configured as follows: an anti-skid sheet is adhered in the clamping groove, and the anti-skid sheet is made of rubber material.

[0014] The utility model is further configured as follows: the anti-skid sheet is provided with a plurality of anti-skid protrusions which are arranged at equal distances.

[0015] The utility model is further configured as follows: the end surface of the fixing plate is provided with an extension block extending into the hardware pipe fitting.

[0027] The moving assembly includes a fixed seat 5, a stepper motor 6 and a ball screw 7. The fixed seat 5 and the stepper motor 6 are respectively placed at the two ends of the slide groove 4, the ball screw 7 is placed between the fixed seat 5 and the stepper motor 6, the output end of the stepper motor 6 is connected to the ball screw 7, the outer peripheral wall of the ball screw 7 is sleeved with a slide seat 8, the positioning seat 2 is placed between the two slide seats 8, and the positioning seat 2 is connected to the two slide seats 8, and the positioning seat 2 moves with the slide seat 8 to adapt to hardware pipe fittings of various lengths.

[0028] Fixing members 9 are correspondingly arranged on the positioning seat 2 and the mounting seat 3 , and the hardware pipe fitting is placed between the two fixing members 9 , and the fixing member 9 extends into the hardware pipe fitting.

[0029] The fixing member 9 includes a connecting pipe 10 and a fixing plate 11 connected to the connecting pipe 10. The diameter of the fixing plate 11 is larger than the outer diameter of the hardware pipe fitting. An extension block 18 extending into the hardware pipe fitting is provided on the end face of the fixing plate 11.
