According to the bearing type bevel gear shaft pitch circle positioning clamp disclosed by the invention, the coaxiality of a machined face and a bevel gear shaft pitch circle reaches 0.005-0.045 mm, and the stable operation and noise reduction effects can be further realized better.
Description
Technical field
The present invention relates to a kind of frock of the processing for spiral bevel gear, relate in particular to a kind of positioning fixture for pitch circle of bearing type bevel gear shaft.
Background technology
The processing of existing spiral bevel gear bearing guard all is to locate the grinding bearing shelves with two centre bores.This grinding method is all the time so that there is the deviation of 0.04-0.08mm in the axiality of spiral bevel gear pitch circle and bearing guard.For a long time, such axiality level has influence on the final noise of bevel gear product always, directly makes the product quality class of bevel gear.Urgent need will have more convenient, rational in infrastructure frock clamp to solve this problem.
Summary of the invention
Technical problem to be solved by this invention is the deficiency for above-mentioned existing counting, and a kind of positioning fixture for pitch circle of bearing type bevel gear shaft that is applicable to without guide bearing shelves spiral bevel gear axle is provided.This positioning fixture for pitch circle of bearing type bevel gear shaft is easy to use, can locate the machining bearing shelves with bevel gear pitch circle, makes bearing guard and bevel gear pitch circle axiality better, and running noise is lower, more steady.
For solving the problems of the technologies described above, the technical solution used in the present invention is: a kind of positioning fixture for pitch circle of bearing type bevel gear shaft comprises that spring, Cone handle, axial cross section are the ring-type holder of spill and are fixedly mounted on the workpiece guiding chuck that is used for leading the part of changing a job on the annular holder; The ring-type holder is made of with the annular double wall that is fixedly connected with base plate base plate, bottom surface and concave surface Cone handle that the two sides of base plate is respectively the ring-type holder are fixedly connected on the bottom surface of base plate, be cavity between annular double wall and the concave surface, at annular double wall near the drift angle place of cavity and along the annular groove that is circumferentially with of annular double wall, be provided with three locking balls in the annular groove, locking ball is provided with positioning through hole; Also be provided with three connecting through holes on the annular double wall; Spring passes connecting through hole and positioning through hole is positioned at locking ball in the annular groove.
As further improved technical scheme of the present invention, also comprise the grinding spindle guiding chuck that turns described ring-type holder be used to leading.
As further improved technical scheme of the present invention, described connecting through hole and locking ball all are three.
As further improved technical scheme of the present invention, the radial section of described annular groove is cambered surface.
As further improved technical scheme of the present invention, described cambered surface is 1/4th cambered surfaces.
The present invention adopts and low high for steel ball workpiece is positioned, and the right spring point of positioning ball is in annular groove, so positioning ball can have small displacement, thereby makes the location of workpiece more accurate.The present invention can guarantee that the axiality of machined surface and bevel gear pitch circle reaches 0.005-0.045mm in a word, also can reach better the effect of smooth running, reduction noise.
