A plurality of groups of elastic positioning components 200 are arranged at the fixed plate 100. A lining stop bar 300 is connected to the plurality of groups of elastic positioning components 200. The circumferential area formed by the outer circumferences of the plurality of groups of lining stop bars 300 is the placement position of the bearing inner ring;

[0029] An adjustment component 400 for adjusting the elastic force of the elastic positioning component 200 is arranged in the middle of the fixed plate 100;

[0030] Among them, the fixing plate 100 positions the inner ring of the bearing by adjusting the elastic force of the elastic positioning component 200 through the adjusting component 400.

[0031] The elastic positioning component 200 includes a guiding groove 201 located at the fixing plate 100. A positioning spring 202 is arranged inside the guiding groove 201. The positioning spring 202 is connected to the inner lining stop bar 300 through a sliding seat plate 203.

[0032] The guiding groove 201 and the sliding seat plate 203 cooperate with each other, so that the sliding seat plate 203 drives the inner lining stop bar to linearly move through the guiding groove 201.

[0033] The adjusting component 400 includes an adjusting plate 401 located at the center of the circle of the fixing plate 100. A driving gear 403 is connected to the lower part of the adjusting plate 401 through a rotating shaft 402. Multiple driven gears 404 are meshed and connected to the outer periphery of the driving gear 403. A shaft rod 405 is connected to the middle parts of the multiple driven gears 404. The shaft rod 405 extends into the guiding groove 201 and is arranged through the sliding seat plate 203, and the shaft rod 405 is located inside the positioning spring 202, so that the sliding seat plate 203 elastically moves inside the guiding groove 201 through the positioning spring 202.

[0036] The working principle of an inner ring positioning tooling for bearing processing provided by the utility model is as follows:

[0037] First, the fixing plate 100 is installed on the bearing processing tabletop, and the elastic force of the positioning spring 202 is adjusted through the adjusting component 400 to adapt to inner rings of bearings with different sizes.

[0038] The inner ring of the bearing is placed outside the circumferential area formed by the inner lining stop bar 300, so that the inner wall of the inner ring of the bearing fits the inner lining stop bar 300, and the elastic force of the elastic positioning component 200 is used to position the inner ring of the bearing.

[0039] If necessary, rotate the adjusting plate 401 to finely adjust the rotation of the driven gear 404, and then adjust the external thread 4051 on the shaft rod 405. Drive the pressing plate 406 to move left and right inside the guiding groove 201 through the external thread 4051, press the positioning spring 202, and the elastic force of the positioning spring 202 increases or decreases under force, thereby adjusting the pressure of the positioning spring 202.

[0040] After the inner ring of the bearing is accurately positioned, subsequent machining operations are carried out.

[0041] After machining is completed, release the pressure of the positioning spring 202, take out the inner ring of the bearing, and prepare for the next machining.

[0042] Although embodiments of the present invention have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
