Description

Technical Field

[0001] This utility model relates to the field of wheel hub processing, and in particular to a wheel hub spoke hole chamfering positioning device. Background Technology

[0002] Motorcycle wheel hub spokes consist of upper spokes and lower spokes. The lower surface of the upper spoke and the upper surface of the lower spoke are both horizontal. After the spoke holes are machined, one of the processes is to remove burrs from the spoke holes on the lower surface of the upper spoke and the spoke holes on the upper surface of the lower spoke by chamfering. If the wheel hub is positioned vertically, the drill bit of the drilling machine will be interfered with by the upper or lower spoke when it moves up and down, making chamfering impossible. Therefore, a wheel hub positioning device needs to be designed to achieve tilt positioning of the wheel hub. Utility Model Content

[0003] In view of the shortcomings of the existing technology, the present invention provides a wheel hub spoke hole chamfering positioning device. The chamfering positioning device can realize the tilt positioning of the wheel hub. After the wheel hub is positioned, it can perform chamfering operation on the spoke holes of the upper or lower spokes.

[0004] To achieve the above objectives, this utility model adopts the following technical solution: a hub spoke hole chamfering positioning device, comprising:

[0005] A positioning seat, wherein the positioning seat is an angle-adjustable positioning platform;

[0006] A rotating assembly includes a rotatable rotating chamber mounted on a positioning platform. The rotating chamber includes a positioning cavity.

[0022] The technical solution of this utility model will be further described below with reference to the accompanying drawings and embodiments.

[0023] like Figures 1 to 4 The hub spoke hole chamfering positioning device shown includes:

[0024] A positioning seat 1, wherein the positioning seat 1 is an angle-adjustable positioning table, wherein the angle-adjustable positioning table can be a workbench of brand name Hanmate and model number 5t;

[0025] A rotating assembly includes a rotatable rotating chamber 2 mounted on a positioning platform. The rotating chamber 2 includes a positioning cavity 3. The top of the rotating chamber 2 has a support edge 4 that matches the spokes of a wheel hub. The outer side of the edge of the support edge 4 has a vertically arranged positioning ring 7. A first positioning pin 8 and a second positioning pin 9 are also provided on the support edge 4.

[0026] A clamping mechanism includes a column 10, which is fixed on a positioning platform, specifically connected to the lower end of the positioning platform. A clamping cylinder 11 is mounted on the column 10 via a crossbeam. The end of the cylinder rod 20 of the clamping cylinder 11 is connected to a rotatable clamping head 12. After the wheel hub 5 is positioned, the clamping head 12 is clamped in the central area of ​​the wheel hub 5.

[0027] The process of using this utility model is as follows: First, the wheel hub 5 to be processed is positioned and connected to the rotating chamber 2. When connecting the wheel hub 5, it is positioned by the two positioning holes on the upper or lower spoke and the first positioning pin 8 and the second positioning pin 9 on the support edge, so that the wheel hub 5 is engaged in the rotating chamber 2. At the same time, it is limited by the positioning ring 7 on the outside of the rotating chamber 2. The spokes of the wheel hub 5 are supported by the support edge 4. In this way, the initial positioning of the wheel hub 5 is completed. After the wheel hub 5 is positioned, the wheel hub 5 is pressed by the clamping mechanism. After the wheel hub 5 is pressed, the drill bit of the drilling machine 18 (the drilling machine can be located at the upper right corner of the right side of the positioning seat to avoid interference with the positioning seat when adjusting its position) can be used to chamfer the spoke holes on the spokes. After the chamfering of one spoke hole is completed, the rotating chamber 2 can be rotated. The rotating chamber 2 drives the hub 5 on it to rotate, moving to the next spoke hole. This process is repeated until all spoke holes are chamfered. Then, the hub is flipped over to continue processing the spoke holes on the other spoke. Specifically, the rotating chamber 2 can be rotated manually or driven by a rotary motor 13 (such as a stepper motor), allowing the rotating chamber 2 to rotate a specified angle each time. Specifically, a mounting plate 14 can be fixed to the motor rod of the rotary motor 13, and the rotating chamber 2 can be directly fixed to this mounting plate 14. When the mounting plate 14 rotates, it will drive the rotating chamber 2 to start rotating.

[0028] Furthermore, one or more chip removal holes 15 are provided at the bottom of the wall of the rotating chamber 2, and the chip removal holes 15 are located on the side of the clamping mechanism. When the spoke holes are chamfered, a large amount of iron filings will be generated. The iron filings will fall directly into the rotating chamber 2. Since the rotating chamber 2 has chip removal holes 15, the iron filings will be discharged directly from the chip removal holes 15, preventing them from accumulating at the bottom of the rotating chamber 2.

[0029] Furthermore, the clamping head 12 is made of cushioning rubber. Specifically, to prevent the clamping head 12 from damaging the wheel hub 5 or causing indentations, the clamping head 12 of this utility model is made of cushioning rubber, thereby effectively ensuring the integrity of the wheel hub 5's appearance.

[0030] Furthermore, a rotary bearing 17 is installed at the end of the cylinder rod 20, and the clamping head 12 is sleeved on the outside of the rotary bearing 17. Specifically, a reduced diameter section is provided at the end of the cylinder rod, and a rotary bearing 17 is fixed on the reduced diameter section and secured with a retaining ring. Then, the clamping head 12 is fixed to the outer ring of the rotary bearing 17. The bottom of the clamping head has an inner ring, which is located directly below the outer ring of the rotary bearing, allowing the clamping head 12 to rotate. When the rotating chamber 2 rotates, it can rotate with the rotation of the hub without interfering with the rotation of the hub 5.

[0031] Furthermore, the bottom of the rotating chamber 2 has a connecting ring 16, which is fixedly connected to the mounting plate 14 by means of the connecting ring 16 and screws. Specifically, this utility model provides a connecting ring 16 at the bottom of the rotating chamber 2, which is fixedly connected to the positioning platform by means of the connecting ring 16 and screws. In this way, different models of rotating chamber 2 can be replaced according to the needs of different models of wheel hubs 5, making the applicability of this device wider.

[0032] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the spirit and scope of the technical solutions of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
