Embodiment Construction

[0021] The present invention will be described in detail below in conjunction with the accompanying drawings and specific examples.

[0022] Such as figure 1 As shown, the tap back angle relief grinding fixture includes a left fan plate 2, a left fan seat 7, a Mohs No. 1 top 9, a tooth limiter 11, a spring top sliding tailstock 16, a sliding connection shaft 29, a right fan seat 31, Right sector plate 34. The left fan-shaped plate 2 and the bottom of the left fan-shaped seat 7 are connected together with the first hexagon socket bolt 5, and the first hexagon socket bolt 5 can be used as the rotating shaft to adjust the rotation. The left fan-shaped plate 2 and the left fan-shaped seat 7 top Connect with square screw 1, thickened gasket 3, and nut 4. The upper part of the left fan-shaped seat is processed with a fan-shaped groove, and the top is engraved with an angle score line. Adjust the angle and lock it with nut 4. Mohs No. 1 top 9 is assembled in the corresponding Mohs ...

Abstract

The invention relates to a working clamp, in particular to a relief-grinding clamp for the relief angle of a screw tap. The relief-grinding clamp comprises a left fan-shaped plate, a left fan-shaped seat, a Mohs No.1 centre, a tooth limiting device, a spring centre sliding tailstock, a sliding connecting shaft, a right fan-shaped plate and a right fan-shaped seat, wherein the lower parts of the left fan-shaped plate and the left fan-shaped seat are connected by hex socket bolts, and the upper parts of the left fan-shaped plate and the left fan-shaped seat are connected by components such as square screws; the Mohs No.1 centre is assembled in a corresponding Mohs hole in the left fan-shaped seat; the tooth limiting device and the spring centre sliding tailstock are mounted on the sliding connecting shaft; and the connecting and adjusting modes of the right fan-shaped plate and the right fan-shaped seat are fully identical to those of the left fan-shaped plate and the left fan-shaped seat. The working clamp has the characteristics that the structure is simple, the operation is flexible and convenient, and the relief angle of the screw tap can be flexibly adjusted without the limitation of a cam of a screw tap relieved tooth grinding machine. Rough machining, semi-finish machining and finish machining can be finished on each tooth of the screw tap during one-time clamping, and the production efficiency is increased.

Description

technical field [0001] The invention relates to a tooling fixture, in particular to a relief grinding fixture for the back angle of a tap. Background technique [0002] At present, domestic ordinary tap removal grinding machines use the cam principle and graduation to process the cutting relief angle of the tap. The cutting relief angle of the tap produced by relief grinding is limited by the cam, which cannot meet the frequent adjustment of the cutting relief angle of the tap during development. And the amount of relief grinding on the back of the blade, and rough machining, semi-finishing, and finishing cannot be completed in one clamping, the production efficiency is low, and it cannot meet the needs of rapid development of various taps. Contents of the invention [0003] In view of a series of problems such as rough machining, semi-finishing, and finishing machining of each tooth relief angle cannot be completed in one clamping and low production efficiency of the exis...
