Abstract

The invention belongs to the technical field of gear machining lathes and discloses a gear hobbing machine small holder repeated positioning and locking device comprising a cutter rest housing and a smaller holder arranged on the cutter rest housing. The device is characterized in that the small holder is provided with a matching portion which contacts with the cutter rest and which is capable of positioning centrally; the cutter rest housing is provided with a pressing device used for tightening the small holder; the same side of the small holder and pressing device are arranged provided with an adjusting gasket used for adjusting the pressing force; the other side of the small holder is provided with a limit device used for limiting circumferential rotation of the small holder. The gear hobbing machine small holder repeated positioning and locking device id capable of positioning repeatedly and automatically, positioning accuracy is high, time for adjusting is shortened, and operating efficiency is improved.

Description

technical field [0001] The invention relates to a gear processing machine tool component, in particular to a repetitive positioning and locking device for a small bracket of a gear hobbing machine. Background technique [0002] The small bracket of the gear hobbing machine is a machine tool component used to support the hobbing tool bar. Its size and position accuracy directly affect the position accuracy of the hobbing tool bar and the product, and then affect the product quality. The positioning of the small bracket of the existing gear hobbing machine generally uses a pressure plate to fix the small bracket on the tool holder shell for positioning. If there is a change, it needs to be re-calibrated, which is very troublesome and time-consuming. Contents of the invention [0003] In view of this, the object of the present invention is to provide a locking device for repeated positioning of the small bracket of the gear hobbing machine, so as to solve the problem of insu...
