High-speed intermittent dividing device and application thereof in gear fly-cutter arc chamfering

Abstract

The invention provides a high-speed intermittent dividing device. The device comprises a slider-crank mechanism, a hydraulic system and a synchronous cog belt gear mechanism, the hydraulic system comprises a plunger pump and a plunger cylinder which are connected together through a one-way valve; the synchronous cog belt gear mechanism comprises a synchronous cog belt and a gear meshed with the synchronous cog belt, and the synchronous cog belt is connected with a piston of the plunger cylinder; and a driving force is converted into reciprocating motion of a piston of the plunger pump throughthe slider-crank mechanism and drives the piston of the plunger cylinder to intermittently move so as to drive the synchronous cog belt to move so that the gear intermittently rotates, thus achievingthe purpose of dividing a workpiece fixedly arranged on the gear. The invention further provides an application of the dividing device in gear fly-cutter arc chamfering. By utilizing the high-speed intermittent dividing device, gear arc chamfering can be continuously carried out without additional cutter relieving actions of the workpiece and a cutter, thus improving the gear chamfering processing efficiency.

Description

technical field [0001] The invention belongs to the field of gear processing, and specifically relates to an indexing device and its application in the arc chamfering of gear flying cutters.
