[0007] The housing is fitted with a pull plate and a fixing block, and the pull plate and the fixing block are connected to each other. The fixing block has a fixing hole inside and a screw hole on its inner side. The roller body has an annular shock-absorbing pad at its inner edge.

[0008] Preferably, the roller body has an internal shaft hole that is compatible with the connecting plate, and the splicing block is engaged and fixed with the splicing groove, which facilitates splicing and combination with the connecting plate through the setting of the shaft hole.

[0009] Preferably, both the connecting disc and the inner edge of the roller body have openings of the same diameter to reduce the amount of material used in the production of the spinning roller.

[0010] Preferably, the inner side of the housing is provided with a guide groove, and the guide groove slides in cooperation with the fixed block. The guide groove improves the guiding nature of the sliding displacement of the fixed block.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Please see Figure 1-4 The present invention provides an embodiment of a special spinning roller for an automobile wheel hub spinning machine, comprising a connecting shaft 1 and a roller body 2. One end of the connecting shaft 1 is connected to a connecting plate 3. The roller body 2 has an internal shaft hole that is adapted to the connecting plate 3. Three splicing blocks 4 are engaged and fixed with splicing grooves 6, which facilitates splicing and combination with the connecting plate 3 through the shaft hole. Three sets of splicing blocks 4 are installed on the outside of the connecting plate 3. One end of the roller body 2 is provided with three sets of housings 5 ​​and splicing grooves 6, and the housings 5 ​​and splicing grooves 6 are interconnected. The three splicing blocks 4 have splicing holes 7 inside. Three sets of fixing members 8 are sleeved on the end of the roller body 2 away from the splicing grooves 6.

[0025] The three housings 5 ​​are fitted with a pull plate 9 and a fixing block 10, and the pull plate 9 and the fixing block 10 are connected to each other. The fixing block 10 has a fixing hole 11 inside and a screw hole 12 inside. The roller body 2 has an annular shock-absorbing pad 13 at the edge inside.

[0026] The inner side of the three housings 5 ​​is provided with guide grooves, and the guide grooves are slidably engaged with the fixing block 10. The guide grooves improve the guiding of the sliding displacement of the fixing block 10. The three sets of pull plates 9 extend out of the outer side of the housings 5 ​​and are provided with limiting plates, and the limiting plates are engaged with the housings 5 ​​to limit the extension and retraction position of the pull plates 9.

[0027] The annular shock-absorbing pad 13 is set at the edge inside the roller body 2. The three splicing blocks 4 are embedded in the inner side of the housing 5 and fit together with the annular shock-absorbing pad 13. By fitting the splicing blocks 4 with the annular shock-absorbing pad 13, the buffering force and shock absorption effect of the roller structure rotation are increased.

[0028] Example 1, such as Figure 1-4 As shown, both the connecting disc 3 and the inner edge of the roller body 2 have openings of the same diameter. By providing opening structures on the outer sides of both the roller body 2 and the connecting disc 3, it is convenient to use the U-shaped insert of an external tool to insert into one of the openings on the outer side of the structurally matched roller body 2 and the connecting disc 3, thereby locking and fixing the rotating surfaces of the roller body 2 and the connecting disc 3 in this state, so that the roller can be maintained and repaired, increasing the functionality and safety of the structure.

[0029] Example 2, as Figure 1-4 As shown, the three fixing parts 8 are positioning bolts. The three fixing parts 8 are fitted into the screw holes 12 and are compatible. The three splicing holes 7 and the screw holes 12 are opposite to each other. The three fixing parts 8 are respectively threaded to the splicing holes 7 and the screw holes 12. Through the positioning bolt structure of the fixing parts 8, it is convenient to extend the fixing blocks 10 when the three sets of splicing blocks 4 on the outside of the connecting plate 3 are embedded in the splicing groove 6. This causes the fixing parts 8 to connect and fix the splicing blocks 4 and the fixing blocks 10 respectively, improves the fixing effect of the bolt tightening, and increases the stability of the spinning roller.

[0030] Working principle: This automotive wheel hub spinning machine uses special spinning rollers;

[0031] During the production of automobile wheel hubs, a connecting plate 3 is installed on the outside of the connecting shaft 1 of the drive structure, and a splicing block 4 is pre-set on the outside of the connecting plate 3. This is matched with the splicing groove 6 structure opened on the inside of the roller body 2 of the spinning machine. Thus, during actual disassembly and assembly, the splicing block 4 is embedded into the splicing groove 6, which enables the connecting plate 3 and the roller body 2 to quickly connect, thereby improving the accuracy and convenience of disassembly and assembly of the spinning roller.

[0032] When the connecting plate 3 drives the splicing block 4 to align with the splicing groove 6, it causes the splicing block 4 to fit closely with the annular shock-absorbing pad 13. By manually pushing the pull plate 9 inside each set of housings 5, the pull plate 9 pushes out the fixing block 10 inside the housing 5 and covers the outside of the spliced ​​splicing block 4, so that the splicing block 4 is fully embedded in the splicing structure inside the roller body 2. Then, the fixing hole 11 in the fixing block 10 is aligned with the splicing hole 7 in the splicing block 4, so that the fixing member 8 can be inserted into the screw hole 12 under the sleeve connection of the screw hole 12 and fixedly connected with the splicing hole 7 and the fixing block 10. This causes the connecting plate 3 and the splicing block 4 to be firmly placed inside the roller body 2 for spinning operations. The calibration, positioning and reinforcement of this structure increases the stability of automobile wheel hub production reinforcement and improves the work efficiency of splicing and disassembling the roller body 2 and the connecting plate 3.
