Description
Technical field
The present invention relates to a kind of governor motion of gear-face profiling chamfering device, belong to machinery manufacturing technology field.
Background technology
Along with rapid economy development, industries such as standard machinery, automobile, motorcycle, coal mining are also prosperous day by day.Transferring power that these industries are required and motion have the Gear Production that changes rotating speed and steering-effecting simultaneously and have also entered the large batch of epoch.Gear Production producer is faced with such difficult problem when producing in enormous quantities: in the Gear Processing process, form sharp edge and residual burr at gear face.And these sharp edges, burr directly affect the quality of gear: these sharp edges and burr, if do not remove, become very hard through behind the carburizing and quenching, the easy tipping of tip surface when the gear fine finishining of road, back, it can scratch the gear teeth face that is engaged with when work, can produce high noisy, particularly evident to high gear.In order to overcome above disadvantage, manufacturer must carry out the sharp edge that forms at increment in the Gear Processing process chamfering and will remain in the burr removal of gear face, i.e. increment chamfered edge.
The nearly four kinds of forms of traditional corner cutting off apparatus: fly cutter chamfered edge method, the automatic chamfered edge method of disk emery wheel, Worm type emery wheel chamfered edge method, end mill continuous division chamfered edge method.These several chamfered edge modes exist following defective mostly: the chamfered edge size is wayward, and tooth depth direction chamfered edge is inhomogeneous, can not realize the full-depth tooth chamfered edge, near position, tooth bottom chamfered edge weak effect; Be subjected to the restriction of diameter and modulus, narrow application range; Transmission and indexing mechanism are complicated, the cost height; Chamfered edge efficient is low.
Along with developing of automobile industry, control proposes higher requirement to chamfered edge with high accuracy, high speed travelling gear for engine, turbine, presses for novel chamfering device.
Summary of the invention
The objective of the invention is to overcome above-mentioned weak point, the governor motion of the wider gear-face profiling chamfering device of a kind of scope of application is provided,,, improve the chamfered edge quality along the even chamfered edge of full-depth tooth of tooth depth direction to realize the accurate control of chamfered edge size.
According to technical scheme provided by the invention, in described governor motion, copying contact is installed in Y on slide, and Y connects to slide with X to slide; Limited block is fixed on the bottom plate; The 4th screw rod screws at Y in the screwed hole of slide; Described bottom plate is enclosed within on described the 4th screw rod, and bottom plate is fixed on X on slide; X connects to slide with Z to slide; First screw rod screws at X in the screwed hole of slide; Middle fixed head is enclosed within on the face of cylinder of first screw rod, and is fixed on Z on slide; Z is installed on the upper mounted plate to slide, and upper mounted plate is enclosed within on the 3rd screw rod; The 3rd screw rod screws at Z in the slide screwed hole; Upper mounted plate is fixed on first slide block; Nut is fixed in the endoporus of first slide block; First slide block is installed in to be regulated on the support, regulates support and is fixed on the slide block in the line slideway auxiliary.
Fixedly connected the 3rd scale knurled nut on the 4th screw rod; The fixedly connected first scale knurled nut on first screw rod; The fixedly connected second scale knurled nut on the 3rd screw rod; Fixedly connected handwheel on second screw rod.
The present invention uses profiling principle chamfered edge, and master pattern is processing parts (gear) itself, need not to manufacture and design master pattern, is fit to the increment chamfered edge of various profiled parts such as straight-tooth, helical teeth, awl tooth and sprocket wheel, and chamfered edge efficient height and transmission mechanism are simple.
Compared with the prior art the present invention has the following advantages: the present invention is simple, compact and reasonable for structure, low cost of manufacture; Carry out the increment chamfered edge owing to use the profiling principle, master pattern is processing parts (gear) itself, need not to manufacture and design in addition master pattern, directly promote the movement locus that copying contact is controlled chamfering tool by the gear that is chamfered (workpiece), transmission system is very simple, so the manufacturing cost of equipment own and client's use cost are lower.The present invention is fit to the increment chamfered edge of various profiled parts such as straight-tooth, helical teeth, awl tooth and sprocket wheel, and versatility is wide.Governor motion has coarse adjustment and micromatic setting two parts among the present invention, and easy to adjust reliable, the big I of chamfered edge is accurately controlled, can be realized the even chamfered edge of full-depth tooth along the tooth depth direction, reached high chamfered edge quality.The present invention can improve the production efficiency of increment chamfered edge greatly.
