Description

Positioning device for worm machining Technical Field The utility model belongs to the technical field of worm machining and positioning, and particularly relates to a positioning device for worm machining. Background The worm is a gear having one or several helical teeth and meshed with the worm wheel to form a pair of staggered axis gears. The indexing curved surface can be cylindrical surface, conical surface or circular ring surface, and has four categories of Archimedes worm, involute worm, normal straight profile worm and conical surface enveloping cylindrical worm, and the surface of the worm needs working procedures of polishing, grinding and the like in the production process. The size specifications of different worms are different, and a single positioning device in the prior art cannot meet the requirements of the worms with various sizes, so that the positioning device needs to be replaced, however, the step of machining the worm is increased in the process, and the machining efficiency is reduced. To this end, the utility model provides a positioning device for worm machining. Disclosure of utility model In order to overcome the deficiencies of the prior art, at least one technical problem presented in the background art is solved.
