The hub is generally fixedly connected by the hub and the spoke coaxial center. For the rim, the production process generally cuts out an aluminum plate meeting the size requirement according to the model size of the hub, and then the aluminum plate unit is rolled and welded. In fact, the rolling device, the bending device and the welding device corresponding to the production and processing mode and even the rolling device are required to be adjusted or customized for different rim blanks produced corresponding to the current hubs of different types, so that production equipment corresponding to the rim blanks is required to be adjusted after the hub model produced each time is changed, the labor intensity is high, and the production efficiency is reduced.

In order to save production cost, hub manufacturers hope that rims with different sizes can use less kinds of blanks as much as possible, so that production time can be shortened and delivery period can be advanced by preparing goods in advance; the method is convenient for purchasing raw materials in advance for production when the price is low according to the price of the raw materials, so that the production cost is further reduced; and the shutdown loss of production equipment can be avoided, and the more effective operation of the inventory and the funds of the production enterprises can be ensured. However, at present, for the production of the hub, the small-batch customized production is carried out, and because the small-batch customized production needs to replace the corresponding equipment mould again, debugging and trial production are involved after the equipment mould is replaced, the mass production can be carried out after the product quality is ensured, the time period of the production of the hub is relatively fixed and longer, and the production cost is higher; in addition, in order to avoid the need of replenishment in the later transportation process and the after-sales process, the products produced in small batch customization are reserved for the customized products, so that the stock cost is relatively high; the final selling price of the product can be further improved.

Therefore, the patent document with the application number of 202111230454.4 provides a production process, which realizes that rims with different axial widths are produced by adopting standard parts for producing large-batch rim blanks, reduces production cost, and effectively combines a large-batch production mode with small-batch customized production at the sales end for reducing cost at the production end of enterprises.

In the above-mentioned process related to each robot, when each robot clips a corresponding annular plate unit, the robot moves to the corresponding annular plate unit according to the image captured by the camera 119, and keeps the annular plate unit clip perpendicular to the axis of the corresponding annular plate unit, the symmetrical clamping plates 110 are positioned at two sides of the annular plate unit, and the driving clamping roller 111 and the driven clamping roller 112 on the same clamping plate 110 are also symmetrically positioned at two sides of the axis of the annular plate unit; then, the clamping plate driving device 114 drives the clamping plate 110 to move towards each other until the driving clamping roller 111 and the driven clamping roller 112 of the clamping plate 110 are simultaneously contacted and clamped with the outer side wall of the annular plate unit; at this time, due to the gravity of the annular plate unit, the annular plate unit tends to move downward with respect to the pinch roller wheels 127 and the pinch roller rotating rollers 126 of the driving pinch roller 111 and the driven pinch roller 112, and because the overtime 110 has a pinching force on the annular plate unit, the anti-slip convex rings 151 provided on the surfaces of the anti-slip cushion layers 141 of the pinch roller rotating rollers 126 are all pressed and deformed corresponding to the positions in contact with the annular plate unit by the pinching force, so that the annular elastic sheets 152 at the corresponding positions are pressed and deformed, and due to the fact that the elastic coefficient of the annular elastic sheets 152 is larger than the anti-slip convex rings 151, the annular elastic sheets 152 exert sufficient relative force on the anti-slip convex rings 151 at the corresponding positions, so that the acting force is provided to make the anti-slip convex rings 151 have a tendency to recover the original state, thereby ensuring the anti-slip effect of the anti-slip convex rings 151. And because the anti-slip cushion layer 141 is connected with the cylindrical groove 140 through the annular corrugated structure 144, and the annular flanging 145 and the connecting sleeve 146 structure arranged on the anti-slip cushion layer 141 prevent the anti-slip cushion layer 141 from moving downwards relative to the cylindrical groove 140 due to the action of the gravity of the annular plate unit, and further ensure the fixing effect of the clamping back of the annular plate unit and the annular plate unit clamp.

And is fixedly connected with the tapered structure of the connection sleeve 146 by the plug body 129, the connection sleeve 146 is further prevented from being separated from the notch of the cylindrical groove 140.

And when the camera 119 needs to observe and judge whether the annular plate unit clamped by the annular plate unit clamp is defective or not, the clamping roller rotating wheel 127 is driven to rotate by the rotating wheel driving device 134, so that the annular plate unit is driven to rotate, and the camera 119 can observe the whole outer side wall of the annular plate unit.

The supporting block 131 of the roller rotating limiting frame 130 is provided with the guide groove 139 corresponding to the plug body 129, and the guide groove 139 is matched with the operation convex ring 153 of the plug body 129 to limit, so that the roller rotating 126 is laterally supported, and the lateral supporting force of the roller rotating 126 is ensured.

Because the clamping roller rotating roller 126 clamps the annular plate unit for a plurality of times for a long time and needs to bear the trend of relative downward movement of the annular plate unit, the anti-slip cushion layer 141 needs to be replaced after the service time of the clamping roller rotating roller 126 is long, and when the anti-slip cushion layer 141 is replaced, the anti-slip cushion layer 141 can be replaced by screwing the plug body 129 to be separated from the central screw 143 in the cylindrical groove 140, and the plug body 129 and the central screw 143 are screwed and fixed again after replacement.
