DETAILED DESCRIPTION

[0023] The technical scheme in the embodiments of the utility model will be described clearly and completely below. All other embodiments obtained by the person skilled in the art without making creative labor belong to the range of protection of the utility model.

[0024] Please refer to Figures 1 to 6 The utility model provides a kind of technical scheme: a clamping tool for gear grinding machine, including support seat body 1, containing cavity 4, prepositioning assembly and fastening structure.

[0025] In the scheme, fixed foot 2 is equidistantly fixed at the bottom end side of support seat body 1, containing cavity 4 is provided at the top of support seat body 1, positioning groove 6 is provided at the bottom end of containing cavity 4, threaded groove 5 is provided at the top end center position of support seat body 1;Prepositioning assembly is provided in containing cavity 4, threaded groove 5 is connected with fastening structure, and fastening structure positions processing gear 3.

[0026] When the machining gear 3 is positioned, a predetermined positioning assembly is provided with a predetermined positioning function, that is, the machining gear 3 is sleeved on the conical cylinder 701, and the conical cylinder 701 is pressed downward until the machining gear 3 is in contact with the support base 1. In this process, the conical cylinder 701 provided supports the inner ring side wall of the machining gear 3, and has a limiting function for the machining gear 3, so that subsequent staff need not adjust the position again. The conical cylinder 701 in the predetermined positioning assembly is placed in the containing cavity 4, and the bottom end surface of the conical cylinder 701 is equidistantly and fixedly provided with an auxiliary spring 702, and the other end of the auxiliary spring 702 is fixedly provided on a support pad 703. The bottom end of the support pad 703 is equidistantly and fixedly provided with a positioning plug 704, and the positioning plug 704 corresponds to the position of the positioning groove 6 in the containing cavity 4, and the two are adaptively inserted.

[0027] The conical cylinder 701 is movably arranged in the containing cavity 4, and the conical cylinder 701 moves downward in a pressed state, and at the same time, the auxiliary spring 702 connected with the conical cylinder 701 is in a compressed state. When the pressure is released, the conical cylinder 701 moves upward under the action of the auxiliary spring 702, and the conical cylinder 701 in the conical cylinder 701 also needs to be fixed under pressure, which is convenient for subsequent replacement and maintenance. When the conical cylinder 701 is not used during machining of the machining gear 3, the conical cylinder 701 can be directly removed.

[0028] In order to further improve the position stability of the machining gear 3, the position of the machining gear 3 is compressed by cooperation of the threaded column 807 and the positioning pressure plate 801. The threaded column 807 in the fastening structure is threadedly connected with the threaded groove 5, one end of the threaded column 807 is fixedly provided with a handle 808, and the handle 808 is fixedly provided with a fastening pressure cylinder 809 at the end connected with the threaded column 807. The threaded column 807 passes through the circular hole body 802 on the positioning pressure plate 801, the positioning pressure plate 801 is provided with an annular anti-skid pattern 804 at one side edge position, and the other side of the positioning pressure plate 801 is symmetrically provided with an auxiliary clamping groove 803 at the hole edge side position of the circular hole body 802. The auxiliary clamping groove 803 is adaptively clamped with the auxiliary clamping block 806, and the auxiliary clamping block 806 is symmetrically and fixedly provided at one end of the anti-loose sleeve 805. The threaded column 807 passes through the anti-loose sleeve 805 and then passes through the positioning pressure plate 801, and the threaded column 807 is threadedly connected with the threaded groove 5. In this process, the auxiliary clamping block 806 at the bottom end of the anti-loose sleeve 805 is clamped in the auxiliary clamping groove 803 on the positioning pressure plate 801, and then the threaded column 807 is tightened by the handle 808, so that the fastening pressure cylinder 809 extrudes the anti-loose sleeve 805, and then extrudes the positioning pressure plate 801, so that the positioning pressure plate 801 finally extrudes the machining gear 3, and the machining gear 3 is stable.

[0029] In order to further improve the pressing stability of the machining gear 3, the anti-loose sleeve 805 is used in cooperation with the positioning disc 801, so as to avoid the problem that the positioning disc 801 is loosened again after the threaded column 807 is screwed again; on the other hand, the anti-skid lines 804 are arranged on the bottom side of the positioning disc 801, so as to further improve the pressing stability of the machining gear 3.
