Novel gear hobbing machine

Abstract

The invention discloses a novel gear hobbing machine and belongs to the field of gear production and machining. The novel gear hobbing machine solves the problem that a gear hobbing machine clamping gear workpieces is complicated at the present stage. According to the technical scheme, the novel gear hobbing machine comprises a rack, a gear hobbing device and a clamping device used for fixing thegear workpieces. The clamping device comprises a fixture insert column, a gear workpiece placing device, a fixture base aligned with the fixture insert column and a driver used for driving the fixtureinsert column to lift to realize matching with the fixture base. The fixture insert column comprises a central shaft and an expansion component which is mounted on the central shaft and clamps and fixes the gears by expansion. The expansion component comprises a sliding sleeve which is movably arranged outside the central shaft in sleeving and sliding modes, an expansion casing pipe which is mounted at the sliding sleeve and a driving piece which is movably arranged at the central shaft in sleeving and sliding modes and can be embedded in the expansion casing pipe. The novel gear hobbing machine is capable of conveniently clamping the gear workpieces and has high clamping efficiency.

Description

technical field [0001] The invention belongs to the field of gear production and processing, in particular to a novel gear hobbing machine. Background technique [0002] The gear hobbing machine is a gear processing machine tool that uses a hob to process straight, helical, and herringbone cylindrical gears and turbine lights according to the generation method. It is the most widely used gear processing machine tool. At this stage, when the gear hobbing machine is being operated, a specific fixture is usually used to clamp and fix the gear workpiece. This fixture generally includes a base, a positioning column adapted to the inner hole of the gear workpiece, and a clamping disc that compresses the gear workpiece , but this method requires the operator to manually clamp and loosen the thread, which makes the workpiece clamping time-consuming and labor-intensive, and the labor intensity of the worker is relatively high. Therefore, it is necessary to develop a new type of gear ...

At this stage, when the gear hobbing machine is being operated, a specific fixture is usually used to clamp and fix the gear workpiece. This fixture generally includes a base, a positioning column adapted to the inner hole of the gear workpiece, and a clamping disc that compresses the gear workpiece , but this method requires the operator to manually clamp and loosen the thread, which makes the workpiece clamping time-consuming and labor-intensive, and the labor intensity of the worker is relatively high. Therefore, it is necessary to develop a new type of gear hobbing machine that is convenient for the installation and fixation of the gear workpiece.
