[0002] A bicycle hub, also known as a "hub barrel" or "axle skin", is a core component in a bicycle wheel set. It is located in the center of the wheel and is responsible for connecting the axle and spokes. The structure of the hub contains a bearing system to support the axle and reduce friction during rotation.

[0003] Existing hub processing usually requires the hub to be installed on processing equipment, one side of the hub is processed, and then the other side of the hub is processed by another set of processing equipment. However, this method cannot achieve one-time molding, has low efficiency, and needs to be switched to another set of processing equipment for processing, which can easily affect the processing accuracy of the hub and is relatively inconvenient.

[0004] Therefore, it is necessary to design a stable hub-specific spindle clamp that can process both sides of the hub at the same time, realize one-time forming of the hub, and improve the hub processing efficiency and accuracy. Utility Model Content

[0006] The technical implementation scheme of the utility model is: a stable hub-specific spindle clamp seat, including a mounting plate, a first fixed ring, screws, a second fixed ring, a rotating ring and a chuck, the mounting plate is provided with two front and rear, the first fixed ring is detachably connected between the mounting plates by a plurality of screws, the second fixed ring is also detachably connected between the mounting plates by a plurality of screws, the second fixed ring is located on the inner side of the first fixed ring, the rotating ring is rotatably connected to the inner side of the second fixed ring, and the chuck is detachably connected to the inner side of the rotating ring.

[0007] Optionally, a support sheet is also included, and a plurality of support sheets are evenly distributed along the circumference on the inner side of the chuck.

[0008] Optionally, the supporting sheets are all trapezoidal.

[0009] Optionally, an air pipe is also included, and two left and right air pipes are connected between the first fixing ring and the lower part of the second fixing ring.

[0010] Optionally, fins are also included, and a plurality of fins are evenly distributed on the outer side of the rotating ring along the circumference, and the fins are all in contact with the second fixed ring.

[0011] Optionally, an air groove is formed on the second fixing ring.

[0012] The utility model has the following advantages: the utility model installs the bicycle hub on the chuck, and then injects gas into the air pipe through the gas injection equipment, so that the gas enters the air groove, drives the rotating ring to rotate, and enables the tool on the CNC lathe to cut and engrave threads on the two sides of the hub according to the preset program, thereby achieving the effect of being able to process the two sides of the hub at the same time, realizing one-time forming of the hub, and improving the processing efficiency and accuracy of the hub.

[0017] In order to make the purpose, technical solution and advantages of the utility model clearer, the utility model will be further described in detail with reference to the accompanying drawings. It is hereby stated that the directional words such as up, down, left, right, front, back, inside, outside, etc. that appear or will appear in the text of the utility model are only based on the accompanying drawings of the utility model, and are not specific limitations of the utility model.

[0018] A stable hub-specific spindle clamp, such as Figure 1-Figure 3 As shown, it includes a mounting plate 1, a first fixing ring 2, screws 3, a second fixing ring 4, a rotating ring 5, a chuck 6, a support sheet 7, an air pipe 8 and a fin 9. The mounting plate 1 is provided with two front and rear ones. The first fixing ring 2 is detachably connected between the mounting plates 1 by twenty screws 3. The second fixing ring 4 is also detachably connected between the mounting plates 1 by twenty screws 3. The second fixing ring 4 is located on the inner side of the first fixing ring 2.
