Description

Ring processing method in oscillating bearing
Technical field
The present invention relates to Machining Technology field, especially relate to ring processing method in a kind of oscillating bearing.
Background technology
Mostly the processing of current oscillating bearing inner ring (such as Fig. 1) is to adopt the mode of machining, and the known way that the inner ring of oscillating bearing process mainly has two kinds: 1) bearing finished product steel ball (hardness HRC60 ~ 64) is sequentially carried out and grinds hole machined in two planes, carbide drill boring, chamfering, mill. This method saves processing technique step, and the spherical difference of sphere and fineness are all fine. But, owing to the hardness of finished product steel ball is high, substantially prolongs the time of reprocessing, cause that work efficiency is very low, and be also easy to cause scorch when polishing both ends of the surface, cause that bearing inner race hardness declines. It addition, use the cutter of hard alloy to result in again the increase of processing cost. 2) GCr15 bar is sequentially carried out blanking, boring, car sphere, facing, car endoporus, heat treatment, mill two plane, cut-in type contouring, mill endoporus, sphere finishing process. This technological method for processing uses common lathe and cutter, processing cost and the 1st) to plant relatively low compared with processing mode and be prone to processing, working (machining) efficiency is high, is suitable for producing in enormous quantities. But cut-in type forming grinding wheel grinding, the spherical difference of sphere is big, and grinding area is big, and sphere is easily burnt, and it is bad that light decorations process surface smoothness, and sphere diameter size dispersion is big, and product qualified rate is low.
Summary of the invention
It is an object of the invention to provide ring processing method in a kind of oscillating bearing, to reduce the processing cost of oscillating bearing inner ring, improve the quality of oscillating bearing inner ring.
In order to solve the problems referred to above, in the oscillating bearing of the present invention, ring processing method is by the following technical solutions: ring processing method in oscillating bearing, the method comprises the following steps: 1) with engine lathe to oscillating bearing inner ring blank car endoporus, plane and sphere, described oscillating bearing inner ring blank is materials in the tube; 2) heat treatment is carried out to through the finished oscillating bearing inner ring blank of step 1) so that it is hardness reaches setting value; 3) with surface grinding machine grinding through step 2) plane of oscillating bearing inner ring blank that processed, make the roughness of plane reach setting value;4) with forming grinding wheel, oscillating bearing inner ring blank is carried out cut-in type contouring, the sphere of oscillating bearing blank is roughly ground; 5) with the endoporus of inner hole grinding machine grinding oscillating bearing blank, the surface roughness of endoporus is made to reach setting value; 6) oscillating bearing inner ring is arranged in order in the V-groove being put under grinder nog plate with separating every tool, sphere grinding is carried out with grinder, ensure surface roughness setting value, every tool or it is that sleeve is every tool every having the ball for bulb diameter is consistent with by the mill final sphere diameter of product, its middle sleeve is d every tool length to be H, external diameter be D, internal diameter, wherein D is equal to the final sphere diameter size (diameter dimension of oscillating bearing inner ring sphere, change along with the change of model) by mill inner ring; H > D; D > Q, Q are equal to bearing face greatest diametrical dimension.
Oscillating bearing inner ring blank is GCr15 materials in the tube.
Step 2) described in setting value be HRC60��64.
Setting value described in step 3) is not more than Ra0.8.
Setting value described in step 5) is not more than Ra0.4.
Setting value described in step 6) is not more than Ra0.2.
The order of step 4) and step 5) can be exchanged.
Owing to ring processing method in this oscillating bearing being using materials in the tube as turned blank, therefore crush grinding surplus is few, sphere of not easily burning on the one hand, improves the quality of oscillating bearing inner ring, the working (machining) efficiency to oscillating bearing inner ring can also be increased on the other hand, reduce processing cost. As can be seen here, present invention reduces the processing cost of oscillating bearing inner ring, improve the quality of oscillating bearing inner ring.

Detailed description of the invention
The embodiment of ring processing method in oscillating bearing, as Figure 2-3, the method comprises the following steps: 1) with engine lathe to oscillating bearing inner ring blank car endoporus, plane and sphere, described oscillating bearing inner ring blank is materials in the tube, in the present embodiment, oscillating bearing inner ring blank is GCr15 materials in the tube. 2) carrying out heat treatment to through the finished oscillating bearing inner ring blank of step 1) so that it is hardness reaches setting value, in the present embodiment, the setting value of the hardness of the oscillating bearing inner ring blank after heat treatment is HRC60��64. 3) with surface grinding machine grinding through step 2) plane of oscillating bearing inner ring blank that processed, make the roughness of plane reach setting value, in the present embodiment, the plane roughness setting value of the oscillating bearing inner ring blank processed through step 3) is Ra0.8. 4) with forming grinding wheel, oscillating bearing inner ring blank is carried out cut-in type contouring, the sphere of oscillating bearing blank is roughly ground; 5) with the endoporus of inner hole grinding machine grinding oscillating bearing blank, making the surface roughness of endoporus reach setting value, in the present embodiment, the setting value of inner bore surface roughness is Ra0.4. 6) oscillating bearing inner ring being arranged in order in the V-groove being put under grinder nog plate with separating every tool, carry out sphere grinding with grinder, it is ensured that surface roughness setting value, wherein this setting value is not more than Ra0.2. In the present embodiment, it is equal to Ra0.2. Every tool for bulb diameter with by the mill consistent ball of the final sphere diameter of product every tool or be sleeve every tool, its middle sleeve is d every tool length to be H, external diameter be D, internal diameter, and wherein D is equal to the final sphere diameter size being ground inner ring; H > D;D > Q, Q are equal to by mill inner ring end face greatest diametrical dimension, and arrangement mode is: one is alternately placed in abrasive sheet V-groove every tool by mill oscillating bearing inner ring one. It is pointed out that before being processed, it is necessary to first carry out the blanking to oscillating bearing inner ring blank, in the present embodiment, the blanking of oscillating bearing inner ring is undertaken by sawing machine cut-out GCr15 materials in the tube.
In oscillating bearing in the other embodiments of ring processing method, step 4) and the order of step 5) in above-described embodiment can also be exchanged; Oscillating bearing inner ring blank can also be (0Cr19Ni9Ti, 1Cr19Ni9Ti, 12Cr19Ni9Ti, GCr15SiMn, GCr4, GCr15SiMo, GCr18Mo etc.).
