Description

[0001] The utility model relates to a clamping device, in particular to a clamping device for polishing a worm tooth surface, belonging to the technical field of worm polishing. Background Art

[0002] Worm drive is a main form of mechanical transmission, with the advantages of compact structure, small size, smooth movement and low noise. In addition, in motion transmission, it has the effect of reducing the upstream error of the transmission system. Therefore, in addition to being widely used for power transmission, it has always been the preferred component of the precision circular indexing mechanism of machine tools and precision instruments. Since worm drive belongs to staggered axis transmission, there is a large relative sliding speed between the working tooth surfaces of the worm wheel and the worm. The tooth surfaces are prone to severe wear and bonding during worm transmission. Therefore, in order to reduce the friction between the tooth surfaces, improve the lubrication performance between the tooth surfaces, and improve its load-bearing capacity, transmission efficiency and precision life, the tooth surfaces of the worm need to be polished.

[0003] The existing polishing method is to use a manual handheld worm to polish the tooth surface against a polishing wheel. This method not only poses a safety hazard to workers, but also has low work efficiency. In addition, it is easy to make the worm tooth surface polished unevenly, affecting the polishing quality.
