Detailed Description
The preferred embodiments of the present invention will be described in detail below with reference to the accompanying drawings so that the advantages and features of the present invention can be more easily understood by those skilled in the art, and the scope of the present invention will be more clearly and clearly defined.
Referring to fig. 1 to 6, the gear ring processing tool comprises a base body 1, an expansion tire 2, a pressing block 3 and a bolt 4, wherein the base body 1 is of a hollow revolving body structure, the outer surface of the upper portion of the base body 1 is processed with a conical surface, the expansion tire 2 is of a cylindrical revolving body structure and is sleeved on the base body 1, the inner side circumferential wall of the expansion tire 2 is provided with the conical surface which is consistent with the outer side taper of the upper end of the base body 1 and matched with the conical surface, the pressing block 3 is of a step-shaped hollow revolving body structure, the lower portion of the pressing block 3 is arranged in the base body 1, the upper shoulder of the pressing block is in interference fit with the top surface of the expansion tire 2, the bolt 4 penetrates through the expansion tire 2 and the pressing block 3 and then is connected and fixed with the base body 1, and the periphery of the cylinder of the expansion tire 2 is provided with at least one slot 6.
Four fixed notches 8 are processed on the flange at the bottom of the base body 1 and used for fixing the whole tool. The upper end of the base body 1 is provided with a circular groove hole 7, the circular groove hole 7 is of a cylindrical structure, the lower portion of the base body 1 is further processed with a screw hole, the circular groove hole 7 is used for internally arranging the pressing block 3, and the screw hole is used for being in threaded connection with the bolt 4. The lower part of the pressing block 3 is matched with the inner circular groove hole 7 on the upper part of the base body 1, so that the pressing block 3 can move up and down conveniently. The bolt 4 penetrates through the expansion die 2 and the pressing block 3 and then is fixedly connected with the base body 1 through threads, and can be in threaded connection or in other connection modes.
