Description
Technical field
This utility model belongs to clamp art, specifically, relates to the outer pitch circle location of a kind of inside spline wheel gear and inserts internal spline fixture.
Background technology
At present, producing inside spline wheel gear processing arrangement and generally adopt external tooth excircle orientation to insert internal spline, this technique requires that in the course of processing cylindrical and end face are that origin reference location is to guarantee internal spline and external tooth axiality.Through repeatedly actually detected, due to car base cylindrical tolerance less (0.03mm), lathe process process being difficult to ensure that, excircle dimension is completely in the margin of tolerance, often occur or excircle dimension exceedes difference and causes cannot assembling during processing internal spline, or occur that because excircle dimension exceedes allowance below nominal size location excesssive gap cannot ensure internal spline and external splines axiality.If realizing the tolerance that cylindrical is so little, then needing to adopt cylindrical grinding and end face to control positioning datum, this creates the terminal the front manufacturing procedure of increase heat, and reducing production efficiency.
Utility model content
For solving above technical problem, the purpose of this utility model is in that to provide the outer pitch circle location of a kind of inside spline wheel gear to insert internal spline fixture, simple in construction, external tooth and internal spline coaxiality control effectively, car base cylindrical tolerance can be amplified, grinding benchmark operation before avoiding heat, production efficiency is higher, and quality control is more stable.
This utility model purpose is achieved in that internal spline fixture is inserted in the outer pitch circle location of a kind of inside spline wheel gear, it it is critical only that: includes clamp base, gear position limiting groove is had in the middle part of this clamp base, the bottom land of described stopper slot has guiding annular groove, fixing hole and through hole, described guiding annular groove and through hole are all arranged concentrically with described stopper slot, the external diameter of described guiding annular groove is equal to the external diameter of described stopper slot, described fixing hole is distributed around described through hole centrosymmetry, the periphery of described stopper slot is provided with 3 trisection graticules, on the sidewall of described stopper slot, corresponding 3 trisection graticules are provided with off-centre operation cambered surface and the standard round bar of 3 centrosymmetry distributions, during use, the lower end part of this standard round bar is in described guiding annular groove, the periphery centrosymmetry distribution of described stopper slot has gear face hold down gag, this hold down gag is fixing with described clamp base to be connected.
Adopt said structure, fixture is connected dish by bolt and fixing hole with workbench to be fixed, within the scope of clamping fixture for correcting end face run-out 0.01mm, load workpiece inside spline wheel gear, insert three same specification standard round bars to rotate along off-centre operation cambered surface lightly at trisection graticule place, make workpiece rotate clockwise or counterclockwise angle Q to can not being rotated further, and correct three same specification standard round bars, meet technological requirement and calibration of workpieces pitch circle；Take off workpiece, end face and three poles will be checked again for after clamp so that it is check that key element meets technological requirement.Then workpiece loading fixture stopper slot, inserts standard round bar, light lathe turner's part, to screwing under low force state, can start processing work internal spline by hold down gag workpiece pressing end face.
Above-mentioned hold down gag includes pressing plate and fastening bolt, and described fastening bolt passes perpendicularly through described pressing plate and threadeds with described clamp base.Adopt said structure, it is simple to the compression of pressing plate and dismounting, easy to operate.
Having installation annular groove bottom above-mentioned stopper slot, this installation annular groove and described stopper slot are arranged concentrically, and described fixing hole is opened on described installation annular groove, form annular brace pad between described guiding annular groove and installation annular groove.Adopting said structure, install annular groove and concede space and be easy in fixing hole installation bolt, supporting pad is little with workpiece bottom contact area simultaneously, and spin friction is little, it is simple to light lathe turner's part, makes correction and detection more accurate.
Beneficial effect:
Internal spline fixture, simple in construction are inserted in the outer pitch circle location of this utility model one inside spline wheel gear, and external tooth and internal spline coaxiality control effectively, to amplify car base cylindrical tolerance, it is to avoid mill benchmark operation before heat, production efficiency is higher, and quality control is more stable.
