[0006] The positioning mechanism includes a positioning piece for tapping positioning, an elastic piece for elastically resetting the positioning piece, a guide sleeve for facilitating the movable guiding of the positioning piece, and a limiting ring for limiting the movable position of the positioning piece;
[0007] The limiting ring is fixedly connected to the end of the guide hole, and the positioning member is movably installed in the guide hole and cooperates with the guide sleeve;
[0008] The elastic member 6 is sleeved on the positioning member and is installed by abutting against each other through a guide sleeve and a limiting ring, and is located at a limiting portion extending radially outward from the outer peripheral wall corresponding to the positioning member.
[0009] In the above-mentioned positioning anti-vibration tap, the corresponding end of the positioning member is arranged in a conical structure, and the guiding and limiting movement is achieved through the cooperation of the limiting portion, the guide hole, the guide sleeve and the elastic member 6 structure.
[0010] In the above-mentioned positioning anti-vibration tap, the auxiliary part and the end of the tap head are arranged in an integrally formed structure, the auxiliary part is arranged on the end of the tap head in an arc structure, and the end of the auxiliary part has an inclined cutting edge for facilitating tapping positioning.
[0011] In the above-mentioned positioning anti-vibration tap, the positioning piece is made of cemented carbide.
[0012] Compared with the existing technology, this positioning anti-vibration tap has the following advantages:
[0013] 1. The structural design is simple. By using the combination of movable positioning parts and fixed auxiliary parts, the positioning parts can be used to perform preliminary center hole positioning during the tapping process. The auxiliary parts can be used to pre-cut the processed hole, realize tap positioning and guidance, and prevent the tap from being misplaced during tapping. BRIEF DESCRIPTION OF THE DRAWINGS
