The wheel 101 will flow out through the wheel conveying channel 45 and cooperate with the hub frame 200. At this time, the first shaft hole 102 on the wheel 101 and the second shaft hole 202 on the hub frame 200 will be on the same axis. The function of the second limiting plate 55 is to prevent the wheel 101 from separating from the hub frame 200.

At this time, the fifth cylinder 73 will be activated first to make the second ejector pin 72 pass through the first shaft hole 102 and the second shaft hole 202 and insert into the rivet gun head 62, which can prevent the wheel 101 and the hub frame 200 from being misaligned. At this time, the fourth cylinder 64 will be activated to push the rivet 300 out of the rivet gun head 62, so that the rivet is inserted into the first shaft hole 102 and the second shaft hole 202.

[0035] As Figure 7 shown and Figure 8 : A further embodiment of the rivet press 80 in the present utility model: The rivet press 80 includes fifth brackets 81 symmetrically arranged on both sides of the main track 2 behind the square box 43 in the conveying direction.

In this way, the slot 11 and the opening 13 can make the end of the sub-track 3 communicate with the front end of the main track 2. When the device is turned on and working, the first vibrating disk 4 will convey the hub frame 200 into the sub-track 3 through the first conveying track 94. When the hub frame 200 moves to the first limit plate 12, the first cylinder 22 will be activated, and the hub frame 200 will be pushed into the main track 2 through the first push plate 23.

As Figure 4As shown: The function of the baffle 54 is that after the rivet is inserted into the first shaft hole 102 and the second shaft hole 202, the third air cylinder 56 will be activated to move the first moving plate 52, so that the second limiting plate 55 is misaligned with the assembled wheel. Then the next hub bracket 200 can be pushed under the wheel conveying channel 45. At this time, the baffle 54 will move into the wheel conveying channel 45 to support the wheel 101, so that the wheel 101 cannot flow out of the wheel conveying channel 45 before the second limiting plate 55 is reset. When the wheel 101 is assembled with the hub bracket 200 and the first shaft hole 102 and the second shaft hole 202 are on the same axis, the rivet will enter the rivet gun head 62 from the feeding pipe 96 under the action of the third vibrating plate 6. At this time, the fifth air cylinder 73 will be activated first to make the second ejector pin 72 pass through the first shaft hole 102 and the second shaft hole 202 and insert into the rivet gun head 62, which can prevent the wheel 101 from being misaligned with the hub bracket 200. Then the fourth air cylinder 64 will be activated to push the rivet 300 out of the rivet gun head 62, so that the rivet is inserted into the first shaft hole 102 and the second shaft hole 202. After the rivet is inserted into the first shaft hole 102 and the second shaft hole 202, it will move between the two sixth air cylinders 82 under the action of the first push plate 23 on the second air cylinder 32. The second position detector 92 will detect whether the wheel 101 has moved to the set position. After the wheel 101 moves between the two sixth air cylinders 82, the sixth air cylinders 82 will be activated synchronously. Under the action of the tapered extrusion block 86 on the ejector rod 84 and the extrusion head 85, one end of the rivet will be deformed to prevent the wheel 101 from separating from the hub bracket 200.
