Description

Technical Field

[0001] The utility model relates to the technical field of bicycle processing, in particular to a pipe surface treatment device for bicycle processing. Background Art

[0002] During the production process, bicycles are assembled from a number of parts. Bicycles are mainly composed of main parts such as the frame, front fork, handlebars, saddle and front fork parts, wheels, and transmission components. The frame is the skeleton of the bicycle and bears the greatest weight of people and goods. According to the working characteristics of each component, it can be roughly divided into the guide system, drive system, brake system, etc. The frame, front fork, handlebars, etc. are made of pipes, and these components need to be surface-sprayed in the last step of the production process. In order to improve the spraying quality and prevent the paint from falling off, the pipes need to be surface-treated. The surface treatment can remove rust, grind the pipe surface smooth, remove stains, etc. to facilitate spraying. For this purpose, this application discloses a pipe surface treatment device for bicycle processing. Utility Model Content

[0006] The screw rod is driven to rotate by rotating the ring handle, so that the screw rod rotates in the shaft tube and causes relative displacement of the screw rod to change the distance between the two cone top shafts, so that the two cone top shafts approach or move away from each other. At the same time, the nut is rotated on the screw rod so that one end face of the nut is pressed against the end face of the shaft tube, so that the screw rod is fixed on the shaft tube, ensuring that the pipe clamped between the two cone top shafts is stable, and at the same time the shaft tube rotates relatively on the wall panel.

[0007] As a further improvement to the above solution, the crossbar is vertically connected to a guide rod, which slides through the top frame;

[0008] The horizontal rising and falling displacements of the cross bar are balanced by the guide rod to ensure the horizontal rising and falling displacements of the grinding roller.

[0009] As a further improvement to the above solution, the nut is arranged on the outside of the wall panel, and the wall panel on this side is symmetrically sleeved on both ends of the shaft tube, and the shaft tube is supported by the two wall panels to ensure smooth rotation of the shaft tube.

[0010] Compared with the existing technology, the utility model has the following advantages: simple structure, reasonable design, novel and unique idea, using the displacement mechanism to clamp the pipe with two conical top shafts, and cooperating with the rotating grinding roller to grind the surface of the pipe to remove burrs, rust, etc. on the surface of the pipe, so as to facilitate spraying treatment on the surface of the pipe. In addition, the grinding roller can be driven up and down by the hydraulic cylinder to be suitable for surface treatment of pipes of different specifications. At the same time, the grinding roller can be displaced to achieve full coverage of the pipe to achieve surface treatment. BRIEF DESCRIPTION OF THE DRAWINGS

[0014] The present invention will be further described below with reference to the accompanying drawings.

[0015] like Figures 1 to 3 As shown in the figure, a pipe surface treatment device for bicycle processing includes a frame 1, and the frame 1 is symmetrically connected to side frames 16 on both sides. Wall panels 2 are symmetrically arranged at both ends of the frame 1. Cone-top shafts 3 are rotatably arranged on the inner side of the wall panel 2, and one of the cone-top shafts 3 is installed on the wall panel 2 through a displacement mechanism 4. A grinding roller 5 is arranged above the two cone-top shafts 3, and the grinding roller 5 is rotatably arranged on the end plate 6. The grinding roller 5 is driven to work by a motor 8. A vertical connecting slide rail 7 is arranged on the outer side of the end plate 6, and the slide rail 7 is arranged on the guide rod 9. A top frame 10 is arranged on the top of the guide rod 9, and a hydraulic cylinder 11 is installed on the top frame 10. The telescopic rod of the hydraulic cylinder 11 is connected to the cross bar 13, and the cross bar 13 is connected to the end plate 6. The lower end of the guide rod 9 is connected to the end of the slide bar 14, and the slide bar 14 is matched and connected to the guide rail 15, and the guide rail 15 is installed on the side frame 16.

[0016] As a further improvement to the above solution, the displacement mechanism 4 includes a shaft cylinder 41, which is rotatably sleeved in the wall panel 2 at one end. The shaft cylinder 41 is internally threaded with a screw rod 42, the inner end of the screw rod 42 is connected to the cone top shaft 3, the outer end of the screw rod 42 is connected to the ring handle 43, and the screw rod 42 is threaded with a nut 44;

[0017] The screw rod 42 is driven to rotate by rotating the ring handle 43, so that the screw rod 42 rotates in the shaft tube 41 and causes the screw rod 42 to move relatively, thereby changing the distance between the two cone-top shafts 3, so that the two cone-top shafts 3 approach each other or move away from each other. At the same time, the nut 44 is rotated on the screw rod 42, so that one end face of the nut 44 presses against the end face of the shaft tube 41, so that the screw rod 42 is fixed on the shaft tube 41, ensuring that the pipe clamped between the two cone-top shafts 3 is stable, and at the same time the shaft tube 41 rotates relatively on the wall panel 2.

[0021] The working principle of a pipe surface treatment device for bicycle processing is as follows: the pipe is clamped by two conical top shafts 3, and the displacement mechanism 4 is used to drive the connected conical top shaft 3 to move to clamp and fix the pipe. Then, the motor 8 drives the grinding roller 5 to rotate, and the hydraulic cylinder 11 drives the grinding roller 5 to contact the pipe surface to grind the pipe surface. The sliding bar 14 is displaced on the guide rail 15 to achieve full coverage of the pipe surface treatment.
