2, the second turntable rotates, and poke rod is made to apply thrust to block, so that the first turntable and the gear coaxially connected occur
The switching of the position of different tooth sockets is realized in the rotation of certain angle, is polished one by one to realize the tooth socket of gear.3, it beats
The reciprocating movement of mill bar, each moving distance is identical, to realize the grinding depth unification to the tooth socket of gear, improves
The precision of processing.
Further, rubber layer is enclosed in the supporting block.Rubber layer is used to increase the friction between supporting block and gear
Power prevents gear from deflecting in process.
Further, the power supply being electrically connected with first motor is additionally provided in the rack, the power supply is equipped with for controlling
The key switch of power supply switching electricity processed, the hollow posts are coaxially connected with for the intermittent cam for contradicting key switch.Work as tooth
Wheel rotation after a week, that is, have been completed the polishing to each tooth socket of gear, cam also has been rotated by one week at this time, cam it is convex
Portion is inconsistent with key switch, realizes power cut-off, first motor is made to stop operating, and prompts staff, and polishing is completed, is convenient for
Staff replaces next gear to be processed in time.
Further, the polishing bar is connected with guide vane wheel far from one end of the second motor.It polishes the rotation of bar, it can be with
Guide vane wheel is driven to rotate synchronously, in the course of rotation, guide vane wheel makes the air of surrounding form one air-flow, and is directed to
In the tooth socket of gear, the scrap that polishing generates timely is removed.
Further, the abrasive grain of multiple outwardly convexs is provided on the outer surface of the polishing bar.Guarantee the effect of polishing,
Keep the polishing degree of each tooth socket of gear unified, promotes the whole quality of gear.
Further, the hairbrush of the outer surface for cleaning polishing bar is equipped in the rack.Hairbrush can be removed in time
It is sticked to the scrap on polishing bar surface.
