Description

Technical Field

[0001] This utility model relates to the field of bicycle hub processing technology, and in particular to a grinding device for processing bicycle hubs. Background Technology

[0002] The bicycle hub, also known as the "wheel hub," is an important component of a bicycle wheel. Located at the center of the wheel, it connects the spokes to the frame and allows the wheel to rotate freely around its central axis. During the manufacturing process, straight-wheel bicycle hubs require a grinding device to smooth and flatten their surface. This ensures that the hub can better engage with the bearings during use, reducing friction and improving performance and lifespan.

[0003] Currently, bicycle hub polishing is done by hand-held polishing machines. However, since bicycle hubs have a sloping surface, it is very difficult for workers to polish this surface, resulting in low polishing efficiency and incomplete polishing. Utility Model Content

However, since bicycle hubs have inclined surfaces, it is very strenuous for workers to grind these surfaces, resulting in low grinding efficiency and incomplete grinding. This utility model provides a grinding device for bicycle hub processing.

[0026] The drive mechanism 6 includes a slide groove 61, a sliding block 62, a hinge 63, a moving plate 64, a horizontal plate 65, and a drive cylinder 66. The L-shaped adjusting plate 52 has a slide groove 61 on one side, and the sliding block 62 is slidably connected in the slide groove 61. One end of the hinge 63 is fixedly installed on the sliding block 62, and one end of the moving plate 64 is rotatably connected to the hinge 63 through a bearing. The other end of the moving plate 64 is fixedly installed on the horizontal plate 65.

[0028] To ensure that those skilled in the art can fully understand the technical solution, this application provides the following overall overview:

[0029] In use, place the bicycle hub on the placement platform 10, then start the drive motor 3. The drive motor 3 drives the grinding disc 4 to rotate, which can grind the surface of the bicycle hub. This avoids the injury to the arms of the operator from holding the grinder for a long time. Then, start the drive cylinder 66. The drive cylinder 66 moves the horizontal plate 65, causing the moving plates 64 at both ends of the horizontal plate 65 to move downwards. This causes the sliding block 62 to move along the slide groove 61, which allows the L-shaped adjusting plate 52 to rotate around the rotating rod 54, thereby enabling the L-shaped adjusting plate to rotate. The drive motor 3 at the other end of 52 tilts, causing the drive motor 3 to drive the grinding disc 4 to tilt, grinding the tilted surface of the bicycle hub. This allows for a more thorough grinding of the bicycle hub. After grinding, the drive cylinder 66 can be activated to allow the sliding block 62 to continue moving. Furthermore, due to the characteristics of the coil spring 55, the L-shaped adjusting plate 52 on the rotating rod 54 can spring back to its original position. During the grinding process, the air pump 11 can be activated to allow iron filings to enter the drawer 12 through the collection hole 9 for collection, thereby saving resources.
