Description

Technical Field

[0001] The present invention relates to the technical field related to the grinding of bicycle hubs, and particularly to a surface grinding mechanism for the processing of bicycle hubs. Background Art

[0002] The hub is an important transmission part of a vehicle and also a key part for isolating moving parts from non-moving parts. Its quality determines the running experience of the vehicle. In the production of hubs, in order to obtain better products, it is necessary to perform surface treatment on the hubs to improve their durability; with the progress of modern technology, surface treatment has become an important way to improve the properties of workpieces and is widely used in basic industrial manufacturing and high-tech industries. Therefore, a surface grinding mechanism is required for processing.

[0003] There are many types of existing surface grinding devices for bicycle hubs. However, when grinding the surface of a bicycle hub, a limiting mechanism is required to limit the side of the bicycle hub. During grinding, the bicycle hub may become loose due to vibration. To solve the above problems, reference can be made to a surface grinding device for bicycle hubs disclosed in the prior art (Chinese Patent with application number CN202222169648.4 and application date August 18, 2022). This grinding device is connected and installed to the bicycle hub body through a motor. At this time, the electric slider slides inside the electric slide rail, and at the same time, the hydraulic rod is started to move the grinding mechanism, so that the grinding mechanism is attached to the outer end of the bicycle hub body, thereby grinding the surface of the bicycle hub body, which is more convenient to use; and reference can also be made to a surface grinding box for the outer surface of a bicycle hub with a cleaning function disclosed in the prior art (Chinese Patent with application number CN202420125037.6 and application date January 18, 2024). This grinding box is convenient for cleaning the ground bicycle hub to avoid residues on its surface. At the same time, the clamping area for the bicycle hub is small, avoiding grinding dead corners; and reference can also be made to an efficient surface grinding device for bicycle hubs disclosed in the prior art (Chinese Patent with application number CN202023152364.1 and application date December 24, 2020). This grinding device integrates rough grinding and fine grinding. When in use, the hub is placed in the hub fixing seat and clamped and fixed. The lifting mechanism drives the rough grinding component to abut against the hub, and the grinding driving mechanism drives the rough grinding component to perform rough grinding on the hub, and the fine grinding cavity performs fine grinding on the hub.

[0004] Although the above-mentioned device can realize the limiting function of the bicycle hub, it still has limitations in actual application. After the bicycle hub is limited, the limited part is difficult to be directly polished due to structural limitations. Therefore, the limited bicycle hub must be disassembled and then the polishing process must be carried out again, which undoubtedly increases the complexity and time cost of the operation process.

[0005] Therefore we have proposed a surface grinding mechanism for bicycle hub processing, in order to solve the above-mentioned problems. Summary of the Invention

A spiral moving pipe is hermetically and slidably arranged on the outer side of the second infusion pipe. The outer side of the spiral moving pipe is threadedly connected to the inside of the adapting plate. A circulation hole is also formed at one end of the adapting plate close to the spiral moving pipe. The outer end position of the circulation hole is connected to a rotating roller, and a fixed impeller is fixed inside the rotating roller.

[0014] Preferably, both ends of the rotating roller are rotatably arranged inside the adapting plate, and the end of the adapting plate is communicated with the shaft end of the rotating roller.

[0015] Preferably, a guiding block is fixed at the outer end position of the second infusion pipe, and the spiral moving pipe forms a sliding structure with the outer side of the second infusion pipe through the cleaning liquid conveyed inside the second infusion pipe.

The specific content is as follows: 1. By driving the rotation of the turntable with the rotation motor, the turntable can rotate at the rear side of the fixed disk, enabling the moving block slidably arranged inside the guiding groove opened on the fixed disk to move in a guided manner. Further, the moving block drives the limiting arc plate to limit bicycle hubs of different sizes. Additionally, an adaptation plate is rotatably provided. By the adaptation plate rotating inside the limiting arc plate, the adaptation plate can be attached to the surface of the bicycle hub, thereby more stably limiting the bicycle hub.

[0018] 2. When the liquid storage tank delivers coolant to the inside of the first liquid delivery pipe and the second liquid delivery pipe, the coolant is discharged through the pressure nozzle on one side of the spiral moving pipe. Further, the coolant drives the liquid to flow through the circulation holes into the inside of the rotating roller. Then, the coolant acts on the fixed impeller inside the rotating roller. Through high-pressure delivery, the fixed impeller drives the rotating roller to rotate inside the adaptation plate. Further, the rotating roller drives the attached bicycle hub to rotate, and different positions are ground by the grinding assembly. BRIEF DESCRIPTION OF THE DRAWINGS

Specific embodiments

[0021] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0022] Please refer to Figures 1-10 , the present invention provides the following technical solution: a surface grinding mechanism for processing bicycle hubs.

[0023] Embodiment 1: In order to adapt to different bicycle hubs for subsequent processing, reference can be made to the attached Figure 1 - attached Figure 5, including a polishing box body 1 and a position adjustment mechanism 25 that can move forward and backward and up and down, which is arranged above the inner wall of the polishing box body 1. The active end of the position adjustment mechanism 25 is fixed to the polishing assembly 26, and a control panel 2 is fixed to the right outer wall of the polishing box body 1; a rotating motor 8 is fixed at the rear end position of the polishing box body 1, and the output end of the rotating motor 8 extends into the interior of the polishing box body 1 and is connected to the adaptation mechanism. The setting of the adaptation mechanism can realize the relative movement of the three sets of limit arc plates 16, thereby adapting to bicycle hubs of different sizes. The surface side wall position of the polishing box body 1 is connected with a cover body 3 through a hinge. A water-influent liquid storage tank 4 is fixed at the top position of the polishing box body 1. The liquid outlets at the left and right ends of the liquid storage tank 4 extend into the interior of the polishing box body 1 through a hose and are connected to the cleaning member 5. The polishing box body 1 is also fixed at the lower position of the adaptation mechanism. The liquid collecting frame 6 and the collecting drawer 7 are also slidably provided at the position directly below the liquid collecting frame 6; the adaptation mechanism includes a turntable 9 fixed to the output end position of the rotating motor 8, and a connecting rod 10 is rotatably provided at the outer position of the turntable 9. The other end position of the connecting rod 10 is rotatably provided at the rear position of the moving block 11. The front end of the moving block 11 is fixed at the rear center position of the limiting arc plate 16, and the outer side of the moving block 11 is slidably provided inside the guide groove 12, and the guide groove 12 is opened through the inside of the fixed plate 13; the connecting rod 10 is provided with three groups at equal angles about the center position of the fixed plate 13, and the moving block 11 forms a sliding structure between the connecting rod 10 and the inside of the guide groove 12; the rear end position of the fixed plate 13 is fixed to the inside of the polishing box 1 by a bracket, and the rear center position of the fixed plate 13 and the turntable 9 are rotatably connected.

[0024] When it is necessary to process the surface of bicycle hubs of different sizes, the bicycle hub is first placed between the three sets of limit arc plates 16, and then the rotary motor 8 is controlled by the control panel 2 to run inside the grinding box 1, so that the turntable 9 fixed at the output end of the rotary motor 8 rotates at the rear position of the fixed disk 13, and then the three sets of connecting rods 10 rotated and set at the outer edge position of the turntable 9 are moved, and then the other end position of the connecting rod 10 drives the rotating connected moving block 11 to slide inside the guide groove 12, so that the moving block 11 The limiting arc plate 16 is driven to slide inside the guide groove 12. Through the three groups of relatively movable limiting arc plates 16, different types of bicycle hubs can be adapted for processing. When processing is in progress, the cover 3 can be closed, and the position of the grinding assembly 26 can be adjusted by starting the position adjustment mechanism 25. The surface of the bicycle hub is ground by the grinding assembly 26. In addition, the cooling liquid is transported to the inside of the cleaning part 5 through the liquid storage tank 4, so that the cooling liquid cools the bicycle hub. In addition, the waste chips are cleaned and collected by the liquid collecting frame 6, and the cooling liquid is collected and processed by the collecting drawer 7.

[0025] Embodiment 2: In order to solve the problem that after the bicycle hub is limited, it is difficult to directly grind the limited position due to structural limitations. Therefore, the limited bicycle hub must be disassembled and then the grinding process is carried out again, which undoubtedly increases the complexity of the operation process and the time cost. Please refer to the attached Figure 1 - attached Figure 10 , rolling mechanisms are arranged at both the left and right ends of the limiting arc plate 16. The rolling mechanism includes an adaptation plate 19 rotatably arranged inside the left and right ends of the limiting arc plate 16 and a rotating roller 21 rotatably arranged at the inner position of the adaptation plate 19; the rear end of the liquid storage tank 4 is also connected to the first infusion tube 14 through a pump body, and the outer end of the first infusion tube 14 is connected to six groups of second infusion tubes 15. The outer ends of the second infusion tubes 15 are fixed to the outer end of the limiting arc plate 16 and are connected to the rolling mechanism; the rolling mechanism includes a second infusion tube 15 made of a hard tube near one end of the limiting arc plate 16. A spiral moving tube 17 is hermetically slidably arranged on the outer side of the second infusion tube 15. The outer side of the spiral moving tube 17 is threadedly connected to the inside of the adaptation plate 19. A circulation hole 20 is also opened at one end of the adaptation plate 19 close to the spiral moving tube 17. The outer end of the circulation hole 20 is connected to the rotating roller 21, and a fixed impeller 22 is fixed inside the rotating roller 21; both ends of the rotating roller 21 are rotatably arranged inside the adaptation plate 19, and the end of the adaptation plate 19 is communicated with the shaft end of the rotating roller 21, and a rotating mechanism is formed between the rotating roller 21 and the inside of the adaptation plate 19 through the fixed impeller 22; a guide block 151 is fixed at the outer end of the second infusion tube 15, and a sliding structure is formed between the spiral moving tube 17 and the outer side of the second infusion tube 15 through the cleaning liquid conveyed inside the second infusion tube 15. A pressure nozzle 18 is also arranged at one end of the spiral moving tube 17 away from the second infusion tube 15. A torsion spring is also connected at the rotational connection position between the limiting arc plate 16 and the adaptation plate 19. The pressure of the pressure nozzle 18 is greater than the elastic force of the torsion spring; the end of the rotating roller 21 away from the spiral moving tube 17 is also connected to the limiting arc plate 16 through a third infusion tube 23, and a plurality of groups of pressure nozzles 24 are equiangularly arranged on the inner side of the surface of the limiting arc plate 16.

[0026] First, the liquid storage tank 4 conveys liquid into the first infusion tube 14, which can then convey the coolant into the second infusion tube 15. As a result, the spiral moving tube 17 slidably arranged outside the second infusion tube 15 is stably guided by the guide block 151, and the spiral moving tube 17 can slide stably inside the adaptor plate 19. The adaptor plate 19 and the spiral moving tube 17 are spirally connected with a relatively large pitch. Thus, the adaptor plate 19 can rotate between the inner sides of the limit arc plates 16 through the spiral moving tube 17, making the outer sides of the adaptor plate 19 and the rotating roller 21 fit against the outer surface of the bicycle hub. When the water pressure continues to increase, the pressure nozzle 18 provided at the end of the spiral moving tube 17 will be in an open state, and the coolant can be discharged through the pressure nozzle 18. The coolant will then flow through the through holes 20 and into the rotating roller 21. Since the fixed impeller 22 is fixed inside the rotating roller 21, the fixed impeller 22 can drive the rotating roller 21 to rotate inside the limit arc plates 16 through the conveyance of the coolant, and the rotating roller 21 can drive the bicycle hub to roll. Also, the grinding treatment of the limit position can be solved. In addition, the coolant is conveyed through the third infusion tube 23 and flows into the limit arc plates 16, and the coolant can polish the surface position of the bicycle hub through the pressure nozzles 24, thus completing the above work.

[0027] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
