Description of the embodiments

The present application is described in further detail below in conjunction with figures 1-2.

The embodiment of the application discloses a multi-aperture grinding wheel positioning jig. Referring to fig. 1 and 2, the multi-aperture grinding wheel positioning jig comprises a positioning disk 41, wherein a threaded hole penetrating through the positioning disk 41 is formed in the central axis of the positioning disk 41, and a positioning column 2 is screwed in the threaded hole. The positioning column 2 is sequentially provided with a plurality of positioning ring tables 21 for the disc sleeving along the axis direction, and the diameters of the positioning ring tables are gradually increased along the direction away from the positioning disc 41, so that the positioning ring tables 21 with different diameters meet the sleeving requirements of discs with different sizes, and meanwhile, when the sizes of all the positioning ring tables 21 on the positioning column 2 cannot meet the disc sleeving requirements, the positioning column 2 with the positioning ring tables 21 with different diameters can be replaced. When a disc of one size is sleeved on the positioning ring table 21 matched with the inner diameter of the through hole, the positioning ring table 21 of the next stage can play a role in resisting the disc, so that the disc is pressed on the positioning disc 41 by the positioning ring table 21 of the next stage after the positioning column 2 is gradually screwed into the threaded hole, and the positioning of the disc is realized. In order to ensure that the disc can be pressed on the positioning disc 41, the positioning disc 41 can be provided with an avoidance groove 11 communicated with the threaded hole for the positioning annular table 21 to enter avoidance. Meanwhile, in order to ensure the pressing force to the disc, the disc is prevented from rotating, and a pressing piece for pressing the disc is further arranged on the supporting plate.

The compressing element comprises a positioning disc 41 arranged at the end part of the positioning column 2, three compressing screws 5 are screwed on the end surface of the positioning disc 41, the three compressing screws 5 are arranged at equal intervals along the circumferential direction of the positioning disc 41, and the positioning column 2 is sleeved with a compression ring 6. After the disc is sleeved on the positioning column 2, three compression screws 5 are screwed so as to be abutted on the compression ring 6, so that the compression ring 6 is compressed on the disc, and the disc is compressed and fixed; meanwhile, the design of the pressing ring 6 increases the pressing surface area pressed on the disc, so that the disc is prevented from being damaged by pressing. The end face of the positioning disc 41 is also provided with an external screw hole 7 for the screw connection of the positioning column 2, so that the positioning column 2 with different new sizes can be directly screw-connected on the original positioning column 2, and the sleeving requirement of the disc is met.

The supporting ring 8 is sleeved on the circumference of the positioning disk 41, a plurality of adjusting screws 9 are arranged on the circumferential side wall of the supporting ring 8, the adjusting screws 9 extend into the supporting ring 8 to be abutted against the positioning disk 41, namely after the positioning disk 41 is clamped by a lathe, the adjusting screws 9 can be screwed, so that the positioning disk 41 and the rotating axis of a disk fixed on the positioning disk 41 are adjusted, and further the machining precision is guaranteed.

The implementation principle of the multi-aperture grinding wheel positioning jig provided by the embodiment of the application is as follows: the diameters of the positioning and changing tables are gradually increased along the direction away from the positioning disc 41, so that the positioning ring tables 21 with different diameters meet the sleeving requirements of discs with different sizes, and meanwhile, when the sizes of all the positioning ring tables 21 on the positioning column 2 can not meet the sleeving requirements of the discs, the positioning column 2 with the positioning ring tables 21 with different diameters can be replaced; and after the disc with one size is sleeved on the positioning ring table 21 matched with the inner diameter of the through hole, the positioning ring table 21 at the next stage can play a role in resisting the disc, so that the disc is pressed on the positioning disc 41 by the positioning ring table 21 at the next stage after the positioning column 2 is gradually screwed into the threaded hole, and the positioning of the disc is realized. After the disc is pressed on the positioning disc 41, the supporting ring 8 is clamped on a three-jaw chuck of the lathe, and then the rotation axis of the positioning column 2 is adjusted by adjusting the screwing depth of the adjusting screw 9, so that the subsequent processing quality is ensured.

The foregoing are all preferred embodiments of the present application, and are not intended to limit the scope of the present application in any way, therefore: all equivalent changes in structure, shape and principle of this application should be covered in the protection scope of this application.
