Title: Wheel rim finishing device

Description:
FIELD 
     The present disclosure relates to the technical field of wheel rim finishing, and more particularly relates to a wheel rim finishing device. 
     BACKGROUND 
     A machined blank of an aluminum wheel is obtained by processes such as smelting, casting and thermal treatment. A rim part of an actual machined blank deforms, and it is particularly serious for the position close to an inner flange, causing that rims of machined blanks of part of wheel types are relatively low in roundness. Problems of eccentricity and failure in machining exist in a machining process, and affect the finished product ratio and the machining quality of the aluminum wheel. In order to solve the problem of failure in machining of blanks, a blank rim would be thickened in actual production, which leads to waste of an aluminum alloy raw material and increase of the cost. 
     SUMMARY 
     In view of this, the present disclosure aims to provide a wheel rim finishing device, which finishes a blank rim before machining to improve the roundness of the blank rim and then improve the finished product ratio and the machining quality of a wheel, and may further reduce the machining volume of a blank and lower the manufacturing cost of the wheel. 
     In order to achieve the above objective, the technical solution of the present disclosure is realized as follows. 
     A wheel rim finishing device includes a stand, a motor and a shaft sleeve I. The motor is fixedly mounted on the stand through the shaft sleeve I. A rotating component is fixed on the stand. A locating disk is arranged on the rotating component. A supporting body is also arranged on the stand, and may do reciprocating motion along a radial direction of the locating disk. The side, away from the locating disk, of the supporting body is provided with a force application screw, and the side, close to the locating disk, of the supporting body is provided with an outer roller. An inner driving roller body and an inner driven roller body are arranged at a position, close to the outer roller, on the inner side of the locating disk. The inner driving roller body is fixedly connected to the output end of the motor, and the inner driven roller body is fixedly connected to the stand. 
     In one embodiment, a weighing sensor is arranged between the supporting body and the force application screw. One end of the weighing sensor is in threaded connection with the force application screw, and the other end of the weighing sensor is fixedly connected with the supporting body. 
     In one embodiment, the rotating component includes a mounting seat fixed on the stand. A thrust ball bearing and a deep groove ball bearing are arranged on the mounting seat in sequence from inside to outside. The locating disk is mounted on the deep groove ball bearing. 
     In one embodiment, a supporting seat I and a supporting seat II are also fixed on the stand. The supporting body is mounted in a guide hole of the supporting seat II. The force application screw is in threaded connection with the supporting seat I and the weighing sensor. 
     In one embodiment, an outer roller mounting seat is arranged between the supporting body and the outer roller. One end of the outer roller mounting seat is fixedly connected with the supporting body. The other end of the outer roller mounting seat is connected with the outer roller through a locating pin. 
     In one embodiment, the inner driving roller body is arranged in the shaft sleeve I, and is connected with the motor through a key. 
     In one embodiment, inner roller heads are arranged on the inner driving roller body and the inner driven roller body. 
     In one embodiment, the inner roller heads are of tooth-form structures. 
     In one embodiment, the outer surfaces of the inner roller heads and the outer roller follow the shape of the structure of a wheel rim. 
     Compared with the prior art, the wheel rim finishing device of the present disclosure has the following advantages. 
     A machined blank rim is finished to improve the roundness of the blank rim and then improve the finished product ratio and the machining quality of a wheel. The wheel rim finishing device has the characteristics of simple structure, easy operation, high universality and the like, and may adapt to wheel types with different rim structures.
