Step two, adjusting treatment: when clamping the spacing end to inner circle 1, rotate motor 5 and start and drive circular cone raceway 11 through rotating disc 61 and placing drum 62 and mutually support and move to the left side of area 94 of polishing, rotate lead screw 934 and drive linkage plate 932 and reciprocate, and then linkage plate 932 and let a block 931 mutually support and can drive polishing plate 92 and open from top to bottom and close, rotate screw 8 again and drive polishing plate 92 through the movable plate 7 on right side and move to the pipe cone raceway in, thereby the regulating plate can polish the processing to the circular cone raceway 11 of different inclination inner circles 1 with polishing area 94 mutually supporting.
Step three, polishing treatment: after the polishing belt 94 is attached to the conical roller path 11, the pulling ropes 97 are connected with each other, then the pulling ropes 97 are wound on the output shaft of the existing reversing motor, the output shaft of the reversing motor drives the pulling ropes 97 to tighten and pay off in the reciprocating rotation process, and then the pulling ropes 97 are mutually matched with the reciprocating connecting plate 96 through the reciprocating spring rod 95 to drive the polishing belt 94 to perform reciprocating polishing treatment on the conical roller path 11.
Step four, cleaning treatment: the cleaning sponge 984 is driven to be attached to the surface of the inner ring 1 through the mutual matching of the fixed plate 981 and the cleaning rack 983 in the process that the moving plate 7 on the left side moves rightwards, so that the polishing debris on the surface of the inner ring 1 can be scraped by the cleaning sponge 984 in the rotating process of the inner ring 1.
The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention, and various modifications and changes may be made by those skilled in the art. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
