Detailed description of the invention
Below in conjunction with the accompanying drawing in the utility model embodiment, be clearly and completely described the technical scheme in the utility model embodiment, obviously, described embodiment is only the utility model part embodiment, instead of whole embodiments.Based on the embodiment in the utility model, those of ordinary skill in the art are not making the every other embodiment obtained under creative work prerequisite, all belong to the scope of the utility model protection.
Gear shaving frock as depicted in figs. 1 and 2, comprise axle 1, the left end of described axle 1 periphery has two parallel plane 1b, the right side of described plane 1b is disposed with axle collar 1c, axle journal 1d and spindle nose 1e, described axle 1 two end faces have left fixing hole 1a and right fixing hole 1f along axle 1 axis, the periphery of described axle journal 1d is the conical surface reduced gradually from left to right, described axle journal 1d periphery is provided with wearing layer, described axle journal 1d place is socketed with cyclic spring expansion set 2, described elastic expansion sleeve 2 inwall is the conical surface 2a coordinated with described axle journal 1d periphery, described elastic expansion sleeve 2 sidewall is provided with several axial breathing groove 2b, described breathing groove 2b end has the circular hole 2c preventing elastic expansion sleeve 2 from ftractureing, described spindle nose 1e has been threaded locking nut 3, the maximum gauge of described locking nut 3 is not more than the external diameter of elastic expansion sleeve 2, tighten or unscrew locking nut 3 and make elastic expansion sleeve 2 swell and reset.
In use, only locking nut 3 is screwed 1 ~ 2 pitch, locking nut 3 is made to screw elastic expansion sleeve 2 right side, in locking nut 3 screwing operations Elastic expansion set 2 swell, thus swelling fixation workpiece, when processing a workpiece, only locking nut 3 is loosened 1 ~ 2 pitch, elastic expansion sleeve 2 is loosened, elastic expansion sleeve 2 elastic reset, thus fast unload workpiece.
In order to promote elastic expansion sleeve 2 elasticity and reseting performance, described breathing groove 2b extends from an end face of elastic expansion sleeve 2 to another end face, and two adjacent breathing groove 2b extend from different end face.
In order to ensure the positioning precision of elastic expansion sleeve 2, the gradient of described elastic expansion sleeve 2 inwall is 1:4, described conical surface 2a is greater than 0.85 with the contact area of the periphery of described axle journal 1d and the ratio of conical surface 2a area, and the coaxiality error assembling rear shaft neck 1d and elastic expansion sleeve 2 can not be greater than 0.02mm.
It is special that in order to ensure elastic expansion sleeve 2 elasticity and reseting performance, the material of elastic expansion sleeve 2 can be 60si2Mn or 20CrMnTi, and through the antiseepage of Overheating Treatment carburizing and quenching spiral shell mosquito, carbon-coating dark 1 ~ 1.4, hardness 58 ~ 63HRC.
Further, described locking nut 3 outer wall is set to step-like, described locking nut 3 is by the nut head 3a largest diameter of elastic expansion sleeve 2 end, described locking nut 3 is regular hexagon away from the cross section of elastic expansion sleeve 2 end vertical axis, and obvious described locking nut 3 also can be arranged to other shape of conveniently tightening and unscrewing locking nut 3 away from elastic expansion sleeve 2 end.
The wearing layer that the periphery of described axle journal 1d is arranged is titanium nitride coating, and titanium nitride coating is very wear-resisting, can effectively prevent axle journal 1d periphery from wearing and tearing, and makes axle 1 Acceptable life long, and effectively preventing affects machining accuracy because of the wearing and tearing of axle journal 1d periphery.
Especially, left fixing hole 1a coordinates a steel ball can measure the distance of steel ball to the end face of axle collar 1c, and adjust position and the stroke of shaving cutter according to this distance, the tooth-formation of gear that such different batches processes is very stable.And two gear shaving frocks can be used to process on a machine tool when planet Gear Processing simultaneously, coordinate steel ball to measure steel ball according to left fixing hole 1a and adjust the position of two gear shaving frocks and the position of shaving cutter and stroke to the distance of the end face of axle collar 1c, can improve planetary production capacity and machining accuracy like this, make engagement between each gear of planetary gear that processes better.
Obvious the utility model is provided with chamfering in each parts junction, the two ends of such as axle 1, axle journal 1d right-hand member.The utility model is specially adapted to planetary processing.
