Abstract
The utility model discloses a double hob gear hobbing machine is designed for improving gear machining speed and centering precision. The newly added widened lathe bed of the gear hobbing machine is fixed on the transverse side surface of the lathe bed, a large carriage is arranged on a transverse guide rail on the widened lathe bed, and an arc-shaped groove is formed in the upper surface of the large carriage; the upper surface of the middle carriage is provided with a longitudinal guide rail, the middle carriage is fixed on the large carriage through a round pin and a centering pin on the bottom surface of the middle carriage, and the round pin is inserted into the arc-shaped groove of the large carriage and can move in the groove; the newly added auxiliary upright post and the tool rest are fixed on the longitudinal guide rail of the middle carriage, and the auxiliary hob is arranged on the auxiliary upright post and the tool rest. The gear hobbing machine adopts double hobs, can simultaneously roll two teeth of a herringbone gear, can reduce one-time clamping and improve the cutting speed. The newly added auxiliary upright post and the tool rest can provide transverse feeding and angle adjustment along the original machine body, so that the centering precision of gear machining is improved.
Description
Technical field
The utility model relates to a kind of thread hob gear-hobbing machine, belongs to gear machining technology field.
Background technology
During general hobbing machine processing herringbone bear, first at tooth base one, sidewinder tooth, then adjust knife rest or workpiece, by tooth base turn-over, clamping again, then in the gear hobbing of tooth base opposite side.This processing mode needs twice clamping, and speed is slow, is difficult for guaranteeing the accuracy of alignment of the both sides gear teeth.
Summary of the invention
The purpose of this utility model is to provide a kind of thread hob gear-hobbing machine, to improve process velocity and the accuracy of alignment of gear.
Concrete technology contents of the present utility model is as follows:
The newly-increased lathe bed of widening of this gear-hobbing machine is fixed on lathe bed transverse side, and the cross slide way of widening on lathe bed is provided with saddle, and saddle upper surface is provided with deep-slotted chip breaker; Middle carriage upper surface is provided with longitudinal rail, and middle carriage is fixed on saddle by the circular pegs on its bottom surface and centring pin, and circular pegs is inserted the deep-slotted chip breaker of saddle, and can in groove, move; On the longitudinal rail that newly-increased secondary column and knife rest are fixed on middle carriage, secondary hobboing cutter is housed on secondary column and knife rest.
This gear-hobbing machine adopts thread hob, can roll two teeth of herringbone bear simultaneously, can reduce clamped one time, improves cutting speed.Newly-increased secondary column and knife rest can provide traverse feed and the angle adjustment along former lathe bed, thereby improve the accuracy of alignment of Gear Processing.

The specific embodiment
Embodiment:
Referring to figs. 1 through 3 couples of embodiment of the present utility model, further illustrate:
This gear-hobbing machine mainly comprises cross slide way 1, widens lathe bed 2, longitudinal rail 3, saddle 4, pay column and knife rest 5, rear column 6, workbench 7, lathe bed 8, knife rest 9, column 10, middle carriage 11, circular pegs 13, centring pin 14, duplex-gear base 15, main hobboing cutter 16 and secondary hobboing cutter 17;
The newly-increased lathe bed 2 of widening is fixed on lathe bed 8 transverse sides, and the cross slide way 1 of widening on lathe bed 2 is provided with saddle 4, and saddle 4 upper surfaces are provided with deep-slotted chip breaker 12.Middle carriage 11 upper surfaces are provided with two parallel longitudinal rails 3, middle carriage 11 is fixed on saddle 4 by the circular pegs 13 on its bottom surface and centring pin 14, circular pegs 13 is inserted the deep-slotted chip breaker 12 of saddle 4, and can in groove, move, middle carriage 11 can be rotated relative to saddle 4 for the center of circle by centring pin 14.On the longitudinal rail 3 that newly-increased secondary column and knife rest 5 are fixed on middle carriage 11, secondary hobboing cutter 17 is housed on secondary column and knife rest 5.
This gear-hobbing machine specific works process is as follows:
After duplex-gear base 15 is placed on workbench 7, transverse shifting workbench 7, main hobboing cutter 16 tool settings, then mobile middle carriage 11, makes secondary hobboing cutter 17 press close to tooth base 15, adjusts the angle of middle carriage 4, center line at the bottom of incision tooth.Main hobboing cutter 16 and secondary hobboing cutter 17 synchronous cuttings, synchro-feed completes processing simultaneously.
This gear-hobbing machine both can roll duplex-gear, also can be by two monocline teeth together clamping, time processing.
