Summary of the invention
The technical problem to be solved in the present invention is to provide a kind of high strength steel race ring profile method for fine finishing, by by clamping workpiece and clamp, by milling profile, quenching, car surface and accurately machined process, high strength steel race ring profile is processed, not only avoid cutter relieving phenomenon occurs, and improve machining accuracy.
For overcoming the above problems, concrete technical scheme of the present invention is as follows: a kind of high strength steel race ring profile clamp, comprises lathe, be fixedly connected with base below lathe, lathe upper surface is provided with feeler block, side end face is provided with handwheel, and the opposite face of handwheel is connected with the mandrel of axis coinciding, and mandrel both sides are provided with stopping means, stopping means is positioned at the upper surface of base, lathe is provided with pressing plate, and pressing plate is positioned at mandrel side, and pressing plate one side end face is provided with clamp nut.
Preferably, utilize the method for fine finishing of high strength steel race ring profile clamp as claimed in claim 1,
1) by high strength steel bearing outer ring clamping on CNC milling machine, utilize CNC milling machine milling profile, leave the surplus of 0.2mm;
2) quench after step 1):
3) step 2) after high strength steel race ring excircle is machined;
4) step 3) clamping high strength steel race ring, is arranged on mandrel by high strength steel race ring, and high strength steel race ring is coaxially connected with mandrel, is fixedly fixed on a side end face of high strength steel race ring by pressing plate, and uses clamp nut locking pressure plate;
5) be that emery wheel on lathe and high strength steel race ring carry out tool setting with feeler block, then with hand wheel of starting, race ring is rotated around axis of workpiece, and wheel grinding high strength steel race ring to surface roughness is 0.8.By feeler block, emery wheel and high strength race ring are carried out tool setting, ensure the uniformity of the rear accessory size of processing, improve machining accuracy.
Preferably, described stopping means is limited post, is symmetricly set on mandrel both sides and vertical with base about mandrel axle center.
The beneficial effect that the present invention brings is: be coaxially connected with mandrel by high strength steel race ring, high strength steel race ring is made to do 180 degree of gyrations by handwheel, high strength steel race ring profile clamp is located by mandrel, ensure that axiality and the circularity of inner bore of part and cylindrical, avoid occurring over-cutting.
Successively workpiece is processed by milling profile, quenching, Vehicle Processing and high strength steel race ring profile clamp step successively, not only make work piece operations process simple, and surface of the work smoothness is improved, and increases work efficiency.
