Abstract
The invention discloses a round pocket hole bearing retainer machining process. The round pocket hole bearing retainer machining process comprises the following steps of 1 roughly turning a first plane and an inner circle, 2 roughly turning a second plane and an outer circle, 3 performing modulation processing, 4 finely turning the first plane and finally turning the inner circle; 5 finely turning the second plane and turning the outer circle, 6 roughly grinding the outer circle, 7 turning an inner step, 8 performing marking, 9 drilling and boring a pocket hole, 10 finally grinding the outer circle, 11 removing burrs, 12 performing dynamic balance, 13 performing optical crosstalk, 14 performing acid pickling, 15 plating silver, 16 performing final inspection and 17 performing package. The round pocket hole bearing retainer machining process is reasonable, the problems of high surface roughness, ball dropping, sleeve mismatching and a large cutter abrasion amount in the prior art are effectively solved, the rejection rate of products is reduced, and various accuracies and production efficiency of the products are obviously improved.
Description
Technical field
The present invention relates to a kind of processing technology of retainer, the round pocket hole retainer processing technology that particularly a kind of machining accuracy is high.
Background technology
For improving the mar proof of Main Shaft Bearing of Engine retainer, need before processing to carry out modulation treatment to blank material.High owing to modulating rear hardness, and the most outside dimension of this type of retainer is large, with interior step, pocket bore dia is large, and multi-band has lock point, and processing difficulties, tool wear is large.To justify pocket hole retainer, as shown in Figure 1, circumferentially pocket hole 20 decile, requires that point differences such as pocket hole are no more than ± 0.02mm to its structure, steel ball must not drop out from interior fore shaft after loading from external diameter direction, and full-size steel ball and retainer combine the minimum outer internal diameter that can easily pass outer ring.Current common process is: step → deburring → dynamic balancing → optical crosstalk → pickling in car shaping → modulation treatment → corase grind cylindrical → thin boring → thin first, second plane → marking → brill of car, boring pocket hole → whole turning → whole boring → car → inspection at end → pack.But the problem that often there will be in existing technique has: 1, there is Vehicle Processing chatter mark on excircle of workpiece surface and interior ledge surface around pocket hole; 2, there is obvious cutter trade in pocket hole surface, is referred to as silk thread; 3, when brill, boring pocket hole, tool wear is fast, and replacement frequency is high, directly affects pocket hole surface roughness and production efficiency; 4, when brill, boring pocket hole, pocket depth difficulty controls, and deeply then occurs falling ball after whole boring, shallow, and assembling fashionable dress does not enter overcoat.There is above-mentioned any one processing problems, all can cause product unrepairable and scrap, causing larger economic loss, therefore for the problems referred to above, be necessary to propose a kind of processing technology that every precision of product and production efficiency can be made all to significantly improve.
Summary of the invention
For the technical problem of above-mentioned existence, the object of the invention is: propose the high and round pocket hole retainer processing technology that production efficiency is high of a kind of machining accuracy.
Technical solution of the present invention is achieved in that a kind of ribbon retainer correcting die processing technology, and its processing technology step is: 1) rough turn first plane and inner circle; 2) rough turn second plane and cylindrical; 3) modulation treatment; 4) thin car first plane and whole boring; 5) thin car second plane and turning; 6) cylindrical is roughly ground; 7) step in car; 8) marking; 9) brill, boring pocket hole; 10) whole cylindrical grinding; 11) deburring; 12) dynamic balancing; 13) optical crosstalk; 14) pickling; 15) silver-plated; 16) inspection eventually; 17) pack.
Preferably, described whole cylindrical grinding is grinding.
Preferably, the cutter in described boring pocket hole adopts the shaped alloys fine boring cutter of dish with a scale.
Due to the utilization of technique scheme, the present invention compared with prior art has following advantages:
One circle pocket hole of the present invention retainer processing technology, its major advantage has: the surface quality improving cylindrical, stop the Vehicle Processing chatter mark on outer round surface, eliminate the Vehicle Processing chatter mark on interior ledge surface, reduce tool wear rate, pocket hole surface roughness improves, and finally improves the accuracy of product, and production efficiency is significantly improved.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, technical solution of the present invention is described further:
Accompanying drawing 1 is circle pocket hole bearing cage structure schematic diagram.
Accompanying drawing 2 is circle pocket hole bearing cage structure perspective view.
Wherein: 1, the first plane; 2, the second plane; 3, inner circle; 4, cylindrical; 5, interior step; 6, pocket hole.
Detailed description of the invention
In order to technological means of the present invention can be better understood, and can be implemented according to the content of description, by following examples and accompanying drawing, technical scheme of the present invention is further described.
Processing technology of the present invention is for processing the round pocket hole retainer shown in accompanying drawing 1,2, and its technique step is: 1) rough turn first plane 1 and inner circle 3; 2) rough turn second plane 2 and cylindrical 4; 3) modulation treatment; 4) thin car first plane 1 and whole boring 3; 5) thin car second plane 2 and turning 4; 6) cylindrical 4 is roughly ground; 7) step 5 in car; 8) marking; 9) brill, boring pocket hole 6; 10) whole cylindrical grinding 4; 11) deburring; 12) dynamic balancing; 13) optical crosstalk; 14) pickling; 15) silver-plated; 16) inspection eventually; 17) pack.
Further instruction:
1, change the final processing mode of cylindrical into grinding by turnery processing, and by this procedure arrangement after brill, boring pocket hole operation, improve the surface quality of cylindrical, stopped the Vehicle Processing chatter mark on outer round surface.
2, completed before hole at brill, boring pocket by step procedure arrangement in car, because now turning is continuous turning, retainer drag is even, eliminates the Vehicle Processing chatter mark on interior ledge surface.
3, whole boring procedure arrangement is completed before hole at brill, boring pocket, the essentially no impact of the precision of change on retainer of secondary operation, when singly making brill, boring pocket hole, pocket depth is easy to grasp, because the size that now pocket hole is put both had been the size of finished product, can can drop out from interior fore shaft by Direct Test steel ball after loading steel ball, the combination physical efficiency of full-size steel ball and retainer easily passes the minimum outer internal diameter of cylindrical.Substantially reduce the brill in brill, bore hole operation, boring processing capacity, greatly reduce the wear rate of drill bit, boring cutter, and the silk thread of pocket hole surface reduces, roughness obviously improves.
4, the cutter processing pocket hole adopts the shaped alloys fine boring cutter of dish with a scale, effectively improves surface roughness and the dimensional accuracy in pocket hole, more easily controls pockets processing size, can be accurate to 0.01mm during debugging.
One circle pocket hole of the present invention retainer processing technology, its process sequence is reasonable, the surface roughness occurred in existing technique is beaten, fall ball, dress does not enter to overlap and the problem of tool wear is all resolved, reduce the percent defective of product, and every precision of product and production efficiency are all significantly improved.
Above-described embodiment is only for illustrating technical conceive of the present invention and feature; its object is to person skilled in the art can be understood content of the present invention and be implemented; can not limit the scope of the invention with this; all equivalences done according to Spirit Essence of the present invention change or modify, and all should be encompassed in protection scope of the present invention.
