Abstract

The invention provides a gear chamfering tool assembly and a vertical gear chamfering machine. The gear chamfering tool assembly comprises a spindle. The spindle is sleeved with a tool shaft coaxial with the spindle and capable of achieving axial limiting. The tool shaft is sleeved with an upper tool disc and a lower tool disc which are coaxially connected with the tool shaft. The lower tool discis fixedly connected with the tool shaft. The upper tool disc is fixed peripherally relative to the tool shaft and can move in the axial direction of the tool shaft. The chamfering tool assembly further comprises a driving mechanism which drives the upper tool disc to move in the axial direction on the tool shaft and has the self-locking function. The driving mechanism drives the upper tool disc to move in the axial direction on the tool shaft so as to adjust the distance between the upper tool disc and the lower tool disc, in order to adapt to the chamfering requirement of gears of differentthicknesses. The gear chamfering tool assembly is easy to operate, the chamfering tool assembly does not need to be disassembled from the gear chamfering machine, the machining auxiliary time is shortened, and the machining efficiency is improved.

Description

technical field [0001] The invention belongs to the technical field of gear processing, and in particular relates to a gear chamfering cutter assembly and a vertical gear chamfering machine. Background technique [0002] The continuous cutterhead full-tooth profile chamfering technology is an efficient and high-quality tooth profile chamfering method, which is widely used in gear chamfering machines. The internal gear tooth profile is continuously extruded, and the metal of the tooth profile is extruded to the end face, and then this part of the metal is cut off from the wheel body with a scraper, so as to realize the chamfering of the gear tooth profile. [0003] For example, CN201310558121.3 discloses a vertical gear chamfering machine, its chamfering knife assembly includes a cutter head, a knife body, a chamfering knife shaft and a sleeve, the knife body is a cylindrical structure, and its outer circumference is provided with a ring The two ends of the web are fixed to ...
