[0020] Example

[0021] In the existing technology, when drilling wheels, the wheel hub placed on the drilling machine needs to be manually positioned to avoid displacement of the drilling position, which would cause the wheel hub to be scrapped. Manual positioning requires constant adjustment of the wheel hub position to ensure the accuracy of the drilling position, which wastes a lot of time and reduces the efficiency of wheel hub processing.

[0022] Please see Figure 1-3 This utility model provides a technical solution: a wheel hub drilling device, including a base 1, a fixing frame 10 installed on the top of the base 1, a positioning component provided on the inner side of the fixing frame 10, and a drilling component provided on the fixing frame 10.

[0023] By setting up a positioning component, the position of the wheel hub is positioned, facilitating its processing and eliminating the need for manual positioning and fixing. This significantly improves the drilling efficiency of the wheel hub. The positioning component includes two electric push rods 2, a first connecting plate 3, and two fixing posts 4. The two electric push rods 2 are fixedly connected to both sides of the fixing frame 10. The first connecting plate 3 is fixedly connected to the push rod ends of the two electric push rods 2. The two fixing posts 4 are fixedly connected to the top of the first connecting plate 3. Two connecting posts 5 are fixedly connected to both sides of the top of the base 1. The outer top is movably fitted with a second connecting plate 6. The top of the second connecting plate 6 has an elongated groove 7, and one end of the second connecting plate 6 has a recessed groove 8. The inside of the recessed groove 8 is movably connected to a roller 9 via a shaft. The push rod of the electric push rod 2 drives the first connecting plate 3 to move, thereby driving the fixed column 4 to move inside the elongated groove 7, so that one end of the second connecting plate 6 rotates around the connecting column 5 as the center, thereby driving the roller 9 at the other end of the second connecting plate 6 to abut against the outside of the hub. By having four rollers 9 abut against the outside of the hub respectively, the position of the hub is positioned.

[0024] By setting up a drilling assembly, the drilling process of the wheel hub can be completed quickly. The drilling assembly includes a hydraulic cylinder 11, a first connecting frame 12, and a first motor 13. The hydraulic cylinder 11 is installed on the top of the fixed frame 10, and the piston rod of the hydraulic cylinder 11 moves through the top of the fixed frame 10. One end of the piston rod of the hydraulic cylinder 11 is fixedly connected to the first connecting frame 12. The first motor 13 is installed at the bottom of the first connecting frame 12, and the output shaft of the first motor 13 is fixedly connected to a second connecting frame 14. Two second motors 15 are fixedly connected to the bottom of the second connecting frame 14, and a drill bit 16 is installed on the output shaft of the second motor 15. The piston rod of the hydraulic cylinder 11 drives the second motor 15 to move downward, and the output shaft of the second motor 15 drives the drill bit 16 to rotate, and then the drill bit 16 drills a hole in the wheel hub. After the drilling is completed, the first motor 13 drives the second motor 15 to rotate a certain angle, and the wheel hub is drilled again through the above steps. The operation is simple and quick.

[0025] Two slide blocks 17 are fixedly connected to the top of the base 1 between the second connecting plates 6. A hub placement plate 18 is slidably connected to the top of the two slide blocks 17. A multi-stage electric push rod 19 is installed at the center of the top of the base 1. The push rod end of the multi-stage electric push rod 19 is fixedly connected to one end of the hub placement plate 18. By placing the hub on the top of the hub placement plate 18, the push rod of the multi-stage electric push rod 19 is reset by controlling the switch group, thereby driving the hub to move to the inside of the roller 9. Two slide rails 20 are fixedly connected to both sides of the top of the base 1. The first connecting plate 3 is slidably connected to the top of the two slide rails 20. The fixing post 4 matches the long groove 7. The fixing post 4 is movably inserted into the inside of the long groove 7. A limit ring is fixedly sleeved on the top of the outer side of the fixing post 4. The limit ring is located above the second connecting plate 6 and limits the second connecting plate 6.

[0026] The working principle or structural principle is as follows: When drilling a wheel hub, the wheel hub is placed on top of the wheel hub placement plate 18. The multi-stage electric push rod 19 is reset by the switch group, thereby moving the wheel hub to the inside of the roller 9. The electric push rod 2 is extended by the switch group, which drives the first connecting plate 3 to move, thereby moving the fixed column 4 inside the long groove 7. This causes one end of the second connecting plate 6 to rotate around the connecting column 5, thereby causing the other end of the second connecting plate 6 to have the roller 9 abut against the outside of the wheel hub. With the four rollers 9 abutting against the outside of the wheel hub, the position of the wheel hub is positioned and fixed below the drill bit 16, making it convenient for processing. Manual positioning and fixing are not required, which greatly improves the drilling efficiency of the wheel hub.

[0027] Then, the piston rod of the hydraulic cylinder 11 is extended by controlling the switch group, thereby driving the second motor 15 to move downward. The second motor 15 is started by controlling the switch group, and the output shaft of the second motor 15 drives the drill bit 16 to rotate, thereby drilling a hole in the wheel hub. After drilling is completed, the first motor 13 drives the second motor 15 to rotate a certain angle, and the wheel hub is drilled again through the above steps. The operation is simple and quick.

[0028] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
