The air outlet hole 41 is arranged toward the central axis of the machine table 2. The trigger structure 32 is used to open the air pump. When the drilling machine 1 completes drilling, the trigger structure 32 is triggered, and the support rods 4 on the four sides eject airflow toward the center of the machine table 2 to blow away the debris generated by drilling, thereby reducing the situation where most of the debris will remain on the workbench after the drilling device works, thereby reducing the situation that will affect the subsequent drilling of the wheel hub 9, and improving the stability of the drilling work.

[0032] Reference Figure 1-Figure 2 The machine 2 includes a working plate 21, a cylinder 22 and a base 23. The cylinder 22 is fixed on the base 23. The telescopic rod of the cylinder 22 is set toward the drilling machine 1. The working plate 21 is inserted and moved on the support rod 4. The working plate 21 is fixed on the telescopic rod. When the telescopic rod is extended, the working plate 21 is driven to move toward the drilling machine 1. When the hub 9 is placed on the workbench, the cylinder 22 is started to drive the working plate 21 to move with the hub 9 toward the drilling machine 1 to perform drilling work. The working plate 21 is inserted and moved on the support rod 4 to limit the range of movement of the working plate 21 through the support rod 4, thereby improving the stability during operation. The air pump is fixed in the base 23 to facilitate the concealment of the air intake pipe to facilitate the movement of the operator. The air outlet 41 is set above the workbench when it is not working.

[0033] Reference Figure 1-Figure 2The trigger structure 32 includes a push button 321 and a boss 322. The boss 322 is arranged on the working plate 21. The boss 322 is located in the center of the working plate 21. The push button 321 is fixed in the center of the drilling machine 1. The push button 321 is arranged toward the working plate 21. When the boss 322 completely abuts against the push button 321, the drilling machine 1 completes the drilling of the end face of the hub 9. When the working plate 21 drives the hub 9 to move toward the drilling machine 1, the boss 322 also moves toward the push button 321. At the same time, it is designed that when the boss 322 completely abuts against the push button 321, the drilling machine 1 also completes the drilling of the end face of the hub 9, realizing the full process automation from drilling to chip blowing, and improving the degree of automation.

[0034] Reference Figure 1-Figure 2 , and also includes a limiting platform 5, which is fixed between the boss 322 and the working plate 21, and the vertical center axis of the limiting platform 5 is colinear with the vertical center axis of the working plate 21, and the diameter of the limiting platform 5 is the same as the inner diameter of the hub 9. The limiting platform 5 can fix the hub 9 on the working table, and at the same time, the limiting of the hub 9 is completed, ensuring the stability and accuracy of the hub 9 during operation.

The closing plate 6 is circular, and the diameter of the closing plate 6 is larger than the diameter of the wheel hub 9. By designing a closing plate 6 to cover the wheel hub 9 during operation, it is possible to reduce debris flying into the inner side of the wheel hub 9 during drilling operation, which makes it difficult for the chip cleaning structure 3 to clean the debris. The bottom surface of the closing plate 6 is flush with the top of the drill needle 11 and the diameter is larger than the diameter of the wheel hub 9, which ensures that the closing plate 6 completes the closure of the wheel hub 9 at the beginning of the operation and ensures that the wheel hub 9 is completely closed. At the same time, the setting of the spring 61 can ensure that the closing plate 6 can automatically reset after the operation.

[0036] Reference Figure 1-Figure 2, and also includes a height-limiting structure 7, which is used to limit the lifting height of the cylinder 22. It avoids the situation that the cylinder 22 is lifted too high, causing the drilling to be too deep and causing the wheel hub 9 to be scrapped. The height-limiting structure 7 includes a height-limiting plate 71 and a movable plate 72. The height-limiting plate 71 is fixed on the base 23. The height-limiting plate 71 is located on one side of the working plate 21 and fits with the working plate 21. The length direction of the height-limiting plate 71 is parallel to the length direction of the support rod 4. A height-limiting groove 711 is provided on the height-limiting plate 71.

The clamping button 721 is pressed, and the telescopic rod of the cylinder 22 changes from extending to retracting. The design of the height limiting plate 71 and the movable plate 72 can effectively limit the lifting height of the cylinder 22, and can design the lifting height and the height of the movable plate 72 so that the operator can easily confirm the height of the movable plate 72 from the outside, thereby ensuring the safety and accuracy of the production process. At the same time, when the clamping button 721 is pressed, the cylinder 22 will be extended and retracted to facilitate the operator to take the punched wheel hub 9 and install the next wheel hub 9, thereby improving work efficiency.

[0037] Reference Figure 1-Figure 2 The height limiting structure 7 is also provided with a chip protection shell 8 on the outside, the chip protection shell 8 is fixed on the working plate 21, and the height limiting structure 7 is provided inside the chip protection shell 8.
