A grinding device for thread cutter tooth profile

Abstract

The invention discloses a thread tool tooth profile grinding and measuring device. Rounding machining performed on a thread tooth crest of a thread tool, the thread tooth outer contour shape is obtained in real time by adopting a camera, tooth profile measuring data is obtained through analysis, and then the tooth profile grinding size is measured in real time. The device comprises a power clamping mechanism, a tooth profile grinding mechanism and an on-line measuring device; according to the power clamping mechanism, the tool (18) is clamped between a support (30) and a tip (17), and a grinding wheel (1) is located at the excircle tangency position of the tool (18); the front end of a fifth support rod (28) is provided with a camera (21) through a block (22), the camera (21) corresponds the position over the tool (18), and a support frame (23) is provided with a light source (20) through a connecting plate (24). According to the thread tool tooth profile grinding and measuring device, the mechanism motion coordination is good, the structure is simple, the tool is directly ground, and therefore the working efficiency and the processing quality are effectively improved; the camera takes pictures and can collect data to find an optimal result, and the small stress is kept.

Description

technical field [0001] The invention relates to the grinding and online measurement of the thread profile of thread cutters, which is suitable for grinding thread profile and thread hob tool profile, and can carry out online measurement of thread profile, and can grind multi-diameter threads The tooth shape of the tool can effectively improve the quality and processing speed of grinding thread crests. Background technique [0002] In the process of rolling out the bolt thread by the thread rolling wheel of the thread tool, the stress concentration of the tooth shape of the screw thread part of the bolt screw is relatively large. The crest and groove are arc transitions, which reduces the concentrated stress during bolt connection and improves the service life of the bolt.

Problems solved by technology

[0003] Nowadays, in the factory, the workers on the job, relying on their experience, use a file to grind the tooth crest of the thread hob rolling wheel, which is time-consuming and labor-intensive, which is not conducive to production, and due to the different operators, the level of There are also differences, so the fatigue strength of the bolts processed by this thread hob is poor in consistency.
