Description
Technical field
The present invention relates to a kind of hollow shaft type parts external grinding auxiliary device.Specifically, a kind of surface roughness and all extra high hollow shaft type parts cylindrical structure grinding servicing unit being applied to aviation field of inside and outside cylinder concentricity requirement is related to.
Background technology
At Field of Aviation Manufacturing, to some hollow shaft type parts surface roughness and inside and outside cylinder concentricity requirement high all especially, usually need the grinding manufacture completing part by cylindrical grinder.It is fixing that the cylindrical of current grinding hollow shaft type parts normally utilizes the three-jaw centering chuck of grinding machine to carry out clamping, three-jaw centering clamping chuck is adopted to carry out the outer bowlder of grinding hollow shaft, hollow shaft is the equal of a cantilever beam on grinding machine, in process, part is more larger away from stiff end circular runout, and mismachining tolerance is larger; Secondly, adopting three-jaw centering clamping chuck to carry out the outer bowlder of grinding hollow shaft needs two port to adjust clamping to realize the grinding of whole cylindrical, and secondary clamping positioning datum inconsistent causing occurs connecing cutter difference, and there is the problems such as working (machining) efficiency is low; Again, because hollow shaft type parts wall thickness is usually thinner, adopt three-jaw centering clamping chuck easily to make clamping part occur distortion, affect connecting elements precision.
Summary of the invention
The object of the invention is to need to exchange two ends to realize whole processing of cylindrical for the outer bowlder of employing three-jaw centering clamping chuck grinding hollow shaft type parts, and in process, circular runout away from stiff end is directly proportional to distance, the problem such as inconsistent and clamping deformation of error.Propose that a kind of structure is simple, easy to operate, machining accuracy is high, a kind of servicing unit that can be applied to grinding hollow shaft type parts cylindrical in batch of good economy performance, thus improve efficiency and the precision of hollow shaft type parts Cylindrical Grinding Processes.
In order to achieve the above object, the present invention adopts concrete technical scheme as follows, a kind of hollow shaft type parts external grinding auxiliary device comprises: mandrel, left end positioning shaft sleeve, left end adjustment axle sleeve, left end hold-down nut, right-hand member positioning shaft sleeve, right-hand member adjustment axle sleeve, right-hand member hold-down nut, described mandrel two ends have center positioning hole for Set and Positioning on grinding machine.Its concrete annexation is that hollow shaft type parts interts on mandrel, and coordinated with mandrel by the inner surface of left end positioning shaft sleeve, left end positioning shaft sleeve outer surface and hollow shaft part left end inner hole and utilize the positioning shaft sleeve shaft shoulder to locate to realize part left end, left end adjustment axle sleeve is arranged between left end positioning shaft sleeve and left end hold-down nut and realizes being fixedly clamped by nut for adjusting part in the position of mandrel; In addition, coordinated with mandrel by the inner surface of right-hand member positioning shaft sleeve, right-hand member positioning shaft sleeve outer surface and hollow shaft part right-hand member inner hole and the positioning shaft sleeve shaft shoulder realize part right-hand member and locate, and right-hand member adjustment axle sleeve is arranged between right-hand member positioning shaft sleeve and right-hand member hold-down nut and realizes being fixedly clamped by nut for adjusting part in the position of mandrel.
Use hollow shaft type parts external grinding auxiliary device of the present invention, the location grinding of batch hollow shaft type parts quick-clamping can be realized, and guarantee that part meets the designing requirement of surface roughness and concentricity.The operation that structure of the present invention is simple, be easy to workman and maintenance, machining accuracy are high, good economy performance, can be applied to grinding hollow shaft type parts cylindrical in batch.
