Composite efficient double-end-face chamfering machine of internal and external teeth of polar coordinates

Abstract

The invention discloses a composite efficient double-end-face chamfering machine of internal and external teeth of polar coordinates. The composite efficient double-end-face chamfering machine is characterized by comprising a gantry frame, a Y-axis servo motor (3), a Y-axis ball screw (4), a Y-axis linear rail (5), a radial positioning slide platform (6), a workpiece (7), a horizontal rectangular bench (9), an X-axis supporting linear rail (10), and an X-axis drive cylinder (11). Polar coordinate composite chamfering movement is realized by utilizing the principle of mechanical profiling. Workpiece rotations are guiding movements, a profiling contact is driven to move radially, beat of the chamfering process is controlled by the guiding movements, and chamfering actions are simple and low in failure rate. Corresponding axial positions of a cutter and the workpiece are adjusted accurately by the servo motor, various chamfering depths can be realized conveniently, different chamfering angles can be realized by changing cutters with different front-end tapers, operation is facilitated and flexible, and controllability is good.

Description

technical field [0001] The invention relates to a gear processing chamfering machine, in particular to a polar coordinate internal and external gear compound high-efficiency double-end face chamfering machine based on the profiling principle, which belongs to the field of advanced manufacturing. Background technique [0002] Gear chamfering can effectively remove the burrs and sharp corners on the edge of the gear teeth, which helps to improve the meshing quality, reduce the contact effect of the gear edges, reduce the meshing noise of the gears, and increase the service life of the gears. [0003] With the further popularization of hard tooth surfaces, gear chamfering has become a very important processing process. Improper chamfering can easily cause stress cracking at the edge of the gear during the quenching process; gear chamfering is indispensable in the gear processing process An important part of. [0004] At present, the main methods of gear chamfering are: manual ...
