Numerical control curved-tooth broaching machine

Abstract

The invention discloses a numerical control curved-tooth broaching machine comprising a broaching machine body, wherein the broaching machine body comprises a machine base, a tool box assembly, a workpiece box assembly, a numerical control device, a lubricating and cooling device and a chip removal device; the tool box assembly and the workpiece box assembly are arranged on the machine base; the tool box assembly is provided with a cutter head headstock, a cutter head, a cutter head main shaft motor, a Z-axis speed reducer, a Z-axis servomotor, Z-axis cutter head feeding and retracting guide rails, horizontal cutter position guide rails, a horizontal cutter position regulator and a horizontal cutter position locking device; the workpiece box assembly is provided with an indexing box seat, an indexing box, an indexing box locking device, vertical cutter position guide rails, a vertical cutter position regulator and an X-axis indexing servomotor and is further provided with a root angle lower seat and a root angle upper seat; the root angle lower seat is provided with vertical double-arc concentric root cone guide rails; the upper seat can slide on the lower seat; the tool box assembly further comprises a root cone regulator and a root cone locking device; and the horizontal cutter position regulator is positioned on the root angle lower seat. Compared with the prior art, the numerical control curved-tooth broaching machine has higher accuracy and rigidity in gear machining.

Description

technical field [0001] The invention relates to a gear broaching machine, in particular to a numerically controlled arc gear broaching machine. Background technique [0002] In the process of processing workpieces of existing gear broaching machines, the indexing box must be rolled up and down, and the scale of the roll is used instead of the root taper angle, which makes the processing operation and adjustment of the machine tool more complicated, and the failure rate is high. Rigidity is difficult to be effectively guaranteed. Contents of the invention [0003] In view of this, the technical problem to be solved by the present invention is to provide a numerical control spiral gear broaching machine with high gear machining accuracy and rigidity. [0004] In order to achieve the above object, the present invention adopts following technical scheme to realize: [0005] A numerically controlled arc tooth broaching machine, comprising a gear broaching machine body having ...
