And polishing the peripheral edge of the rim smoothly. The punching of the central shaft is completed while the hub is polished, so that the labor cost is saved, and the hub pretreatment efficiency is also improved.

In the above technical solution, it should be noted that, after the hub is mounted on the clamping assembly 2, it is necessary to keep the gap between the ribs on the hub facing the latch 4.1, so that the latch 4 can be just aligned with and latched to the ribs on the hub after descending along with the punch 3.1, generally, the scraper 6 is used as a reference, and it is only necessary to make any one of the clamping portions 2.2 of the clamping assembly 2 correspond to the relative position of the scraper 6 at each time, for example, one of the clamping portions 2.2 coincides with the scraper 6. Correspondingly, suitably reduce the size of latch 4.1, even the size of latch 4.1 is less than the clearance between two adjacent ribs, can be favorable to joint portion 4 joint to in the clearance of each rib. Based on this situation, referring to fig. 5, in another embodiment of the present invention, the present invention further includes a misalignment automatic alignment structure 7, the misalignment automatic alignment structure 7 includes a first loop bar 7.1, a second loop bar 7.2 and a first elastic unit 7.3, the first loop bar 7.1 is rotatably connected to the periphery of the punch bar 3.1, the first gear 5.1 is coaxially and fixedly connected to the first loop bar, the second loop bar 7.2 is vertically and slidably disposed on the periphery of the first loop bar 7.1, the bottom of the second loop bar 7.2 is fixedly connected to the clamping portion 4, the second loop bar 7.2 is driven to slide downward by the process of the first elastic unit 7.3 recovering deformation, preferably, the first elastic unit 7.3 is a first compression spring, two ends of the first compression spring respectively abut against the first gear 5.1 and the clamping portion 4, and the first loop bar 7.1 is driven by the driving assembly 5 to rotate the clamping portion 4. Through the arrangement of the dislocation automatic alignment structure 7, before the clamped hub is punched every time, the rotating hub is not required to be rotated to enable the gaps among the ribs to be over against the clamping teeth 4.1, when the punch 3.1 descends to punch the clamped hub, the following two conditions can occur, the first condition is that the clamping teeth 4.1 of the clamping part 4 are directly clamped into the gaps among the ribs of the hub, and the clamping part 4 drives the hub to rotate; the second kind is, in the clearance of latch 4.1 misalignment to each rib of joint portion 4, latch 4.1 and rib clearance dislocation promptly, but the upper surface of rib is received in latch 4.1 bottom butt, joint portion 4 and second pole body can stop descending because of the rib hindrance, the descending stroke of impact beam 3.1 and the first body of rod this moment will continue, the shaft hole of wheel hub is washed out to impact beam 3.1 bottom, and in this process, the first body of rod has produced the slip relative to the second body of rod, and first elastic unit 7.3 is compressed further simultaneously. Next, second gear 5.2 drive first gear 5.1 rotates, first gear 5.1 drives first body of rod and rotates, first body of rod drives the second body of rod and joint portion 4 rotates, because produce the resistance between the burr on wheel hub and the scraper 6 this moment, be greater than 4.1 butt ribs of latch and produce frictional force far away, therefore, wheel hub and centre gripping subassembly 2 keep static, only joint portion 4 rotates, when 4.1 rotates the space department between the ribs, the elasticity of first spring can make 4 and the second body of rod downstream of joint portion rapidly, make 4.1 the card of latch advance in the space between the ribs, thereby realize 4 and wheel hub's joint of joint portion, 4 drive wheel hub of joint portion and centre gripping subassembly 2 rotate, thereby can automatic alignment and joint when having realized 4.1 of latch and rib clearance dislocation. After the grinding contact, the clamping part 4 is separated from the hub by self only by lifting the power unit element punch 3.1.

In a few cases, a relatively thick and hard block-shaped burr appears on the rim peripheral side of the individually cast hub, and is included in the common burr, which is difficult to find without careful observation, and after the block-shaped burr is contacted with the scraper 6, the scraper 6 is easy to break, so that an operator needs to roughly check the hub before placing the hub on the clamping component 2, so as to pick out the hub with the block-shaped burr to protect the scraper 6, and even then, the situation of omission exists at all. Based on the above situation, in another embodiment of the present invention, referring to fig. 4, on the basis of the previous embodiment, one side of the latch 4.1 is an inclined surface or an arc surface, and the inclined surface or the arc surface abuts against the side surface of the rib. So, at the beginning that servo motor 5.3 started, 4 drive wheel hub of joint portion begin the pivoted in-process, in case the cubic burr at rim edge is run into to scraper 6, 4 can react rapidly of joint portion: latch 4.1 is inclined plane or arcwall face with rib butt face, and 4 rotations of joint portion will make latch 4.1 follow the roll-off in the rib clearance, and 4 idle rotations of joint portion, latch 4.1 when 4 idle rotations of joint portion and rib clearance block repeatedly, break away from can produce "the sound of clicking" to remind operating personnel to close drive assembly 5, thereby protection scraper 6.
