[0027] Further refinement of the embodiment of the present utility model is as follows: Figure 1 and Figure 2As shown, the fixing assembly includes an electric push rod 12, a mounting rod 13 and a V-shaped clamping block 14. The electric push rod 12 is symmetrically arranged on the placement table 11. The electric push rod 12 is connected to the mounting rod 13 which is slidably matched with the placement table 11. A V-shaped clamping block 14 is arranged on the top of the mounting rod 13, and two V-shaped clamping blocks 14 are arranged opposite to each other. The significance of arranging the mounting rod 13 is that the V-shaped clamping block can effectively fix the central position of the wheel hub blank. Even if the wheel hub blank of different sizes is replaced, the clamping can also be completed within a certain central range. The wheel hub blank of different sizes can be effectively fixed by the fixing assembly, the clamping effect is stable, and the quality is guaranteed after the center hole of the subsequent wheel hub blank is opened.

[0028] Further refinement of the embodiment of the present utility model is as follows: Figure 1 and Figure 2 As shown, the punching assembly includes an electric cylinder 21, a motor box 22 and a drill bit 23. The electric cylinder 21 is arranged on the mounting plate 2. The electric cylinder 21 is connected to the motor box 22. A servo motor is arranged in the motor box 22. The servo motor is not shown in the figure. The servo motor is connected to the drill bit 23.

[0029] Further refinement of the embodiment of the present utility model is as follows: Figure 1 and Figure 2 As shown, the mounting plate 2 is symmetrically provided with a slide groove 24, a guide plate 25 is slidably fitted in the slide groove 24, the electric cylinder 21 is connected with the guide plate 25, and a motor box 22 is provided on the guide plate 25; the punching assembly can realize an efficient punching process for the center hole of the hub blank and the position of the punching assembly is uniquely determined during the lifting movement and will not deviate.

[0030] Further refinement of the embodiment of the present utility model is as follows: Figures 1 to 3 As shown, the chip extraction component includes a suction pipe 32, an air pump 33 and a rectangular pipe opening 34. The air pump 33 and the symmetrically distributed suction pipe 32 are arranged on the collection box 31. The air pump 33 and the suction pipe 32 are both connected to the interior of the collection box 31. One end of the suction pipe 32 is obliquely provided with a rectangular pipe opening 34. The rectangular pipe opening 34 is higher than the height of the drill bit 23. The filter screen 35 is located below the input end of the air pump 33 to prevent the debris from being sucked into the air pump 33. The chip extraction component effectively sucks the debris generated during the punching process of the hub blank, reduces the amount of debris splashing to the outside, and thereby reduces the labor intensity of subsequent manual cleaning. The rectangular pipe opening 34 can increase the suction area of ​​the debris.

[0031] Further refinement of the embodiment of the present utility model is as follows: Figure 3As shown, the cleaning component includes a cylinder 41, a mounting block 42 and a scraper 43. The cylinder 41 is arranged on the collection box 31, and the cylinder 41 is connected to the mounting block 42 located inside the collection box 31. The mounting block 42 is provided with a scraper 43, and the scraper 43 cooperates with the filter screen 35 to scrape away debris and prevent blockage. The cleaning component is used to clean the debris attached to the filter screen to the bottom of the collection box in time, and the material is cleaned out in time with manual work, so as to avoid clogging of the filter screen due to long-term use, thereby affecting the suction effect.

[0032] It should be noted that the electric push rod 12 , the electric cylinder 21 , the servo motor, the air pump 33 and the air cylinder 41 are all electrically connected to the controller, which is not shown in the figure.

[0033] The workflow of this utility model:

[0034] First, place the wheel hub blank on the placement table 11 and between the two V-shaped clamping blocks 14. Then the controller controls the two electric push rods 12 to work simultaneously to drive the V-shaped clamping blocks 14 close to the wheel hub blank. When the two V-shaped clamping blocks 14 are in contact with the wheel hub blank, the fixation is completed and the placement orientation of the wheel hub blank is defined. At this time, the drill bit 23 is just above the center of the wheel hub blank. Similarly, before replacing wheel hub blanks of different sizes, the controller first controls the two electric push rods 12 to work and retract simultaneously to ensure that the placement of the wheel hub blank on the placement table 11 is not hindered. When the wheel hubs of different sizes are replaced, the two electric push rods 12 are controlled by the controller to work and retract simultaneously. After the blank is placed, the controller controls the electric push rod 12 to repeat the above process to complete the limitation. After the placement position of the hub blank is limited, the controller controls the electric cylinder 21 and the servo motor to work at the same time. The operation of the electric cylinder 21 can drive the drill bit 23 to move down, and the operation of the servo motor can drive the drill bit 23 to rotate at high speed. It should be noted that the drill bit 23 does not need to completely enter the hub blank to complete the drilling process. In this way, the drill bit 23 can contact the center part of the upper surface of the hub blank and perform the center hole drilling process. A large amount of debris will splash during the drilling process. At this time, the controller controls the air pump 33 works in reverse suction, and then most of the debris splashed outward during the process of drilling the center hole of the hub blank by the drill bit 23 will be sucked into the collection box 31 through the rectangular pipe opening 34 and the suction pipe 32. Due to the existence of the filter screen 35, the debris will not be sucked into the air pump 33 to reduce its service life. A part of it will remain on the filter screen 35, and the other part will fall to the bottom of the collection box 31. After a period of time and a certain number of hub blank drilling processes, the controller will control the cylinder 41 to perform a contraction movement so that the scraper 43 contacts the debris on the filter screen 35 to scrape the material. At this time, most of the debris falls into the collection box. At the bottom of the collecting box 31, the sealing door is opened to clean the debris inside the collecting box 31. At the same time, the filter screen 35 can be replaced to ensure the subsequent use effect. This can avoid excessive accumulation of debris in the collecting box 31 to affect the subsequent suction effect. Compared with the prior art, the device can effectively fix the position of wheel hub blanks of different sizes, with good fixing effect and stable clamping. At the same time, the debris generated during the punching process can be effectively sucked, which effectively reduces the amount of debris splashing and reduces the labor intensity of subsequent cleaning by the staff. The center hole punching process of the wheel hub blank is fast and efficient.
