Description
(1) technical field
The present invention relates to a kind of manufacturing technology of retainer, specifically a kind of processing method of secondary bearing entity combination holder support.
(2) technical background
Mostly the cage pin processing method of prior art is that adopting the patent No. is ZL:91106705.1, name is called: the patented technology of " manufacture method of the pillar of retainer " is processed into metal bar material after the cross section meets the cage pin sectional shape, again metal charge is cut into a column length that needs, again the pillar stock of above-mentioned well cutting is processed on milling machine at last.Milling machine processing is that pillar stock to be processed is placed on the milling machine frock of linearly feeding, and the pillar stock clamps it with manual type on the milling machine frock, and integral body moves on the milling machine end of pillar stock is processed until meeting technological requirement; Then the pillar stock is unloaded from the milling machine frock, the turnover support stock also attaches it on the milling machine frock and to continue the other end of pillar stock is processed until meeting technological requirement.In the milling machine course of working, the milling machine cutter head rotates but does not have change in displacement, move back and forth the cutting of realization by the milling machine frock to the pillar stock, the moving direction difference of milling machine frock makes the contact stress between milling machine cutter head and the pillar stock differ in size, thereby causes the generation and the expansion of machining error; In addition, twice on the milling machine frock of pillar stock installs and fixes, and also can cause the generation and the expansion of machining error; At last, because the fixedly employing manpower of pillar stock on the milling machine frock clamps the method for control, different people is difficult to control with same people in different dynamics sizes constantly, and this also is the another big factor that causes machining error to produce and enlarge.In a word, the existence of above-mentioned three kinds of factors makes and adopts the pillar of milling machine processing to have following defective and deficiency: 1) work efficiency is low, and labor intensity is big; 2) machining accuracy is not high, the bad control of tenon side-play amount, and excessive too small phenomenon often appears in side-play amount; 3) inconvenience is installed, the pillar that processes often because of process quality issue causes difficulty is installed, and the bearing quality that makes after installing is not high when installing on retainer, very flexible, noise are big at work, that bearing temperature is raise is too fast excessive because of frictional heating, and bearing life is reduced for bearing.
(3) summary of the invention
Technical assignment of the present invention is at the deficiencies in the prior art, the cage pin precision that a kind of processing technology is simple, labor strength is low, automaticity is high, process height is provided, the processing method of secondary bearing entity combination holder support easy for installation, flexibility is strong at work, noise is little, heating value is few for the bearing that the pillar that is processed into this method is made, improve working life greatly.
The technical solution adopted for the present invention to solve the technical problems is:
A kind of processing method of secondary bearing entity combination holder support, comprise the processing of pillar stock, the pillar stock that processes in advance is fixed on the discoidal car post frock, and the both ends of the surface that make the pillar stock are exposed discoidal car post frock, to be fixed with the disc car post frock overall fixed of pillar stock on the frock seat of lathe, utilize the feed movement of lathe cutter head and rotatablely moving of car post frock, realization is to the pillar stock cutting of an end face wherein, after this end face completion of processing, car post frock is pulled down from the frock seat of lathe, and then car post frock oppositely is installed and processes the other end of pillar stock, the both ends of the surface of pillar stock are processed finish the back the pillar finished product, the pillar finished product unloaded from car post frock get final product.
Above-mentioned lathe is preferably numerically controlled lathe.
Above-mentioned frock seat is provided with the frock securing means, and the frock securing means comprises tool locating device and fastening positioning device, and car post frock is arranged on the tool locating device, and fastening positioning device is connected with high pressure cylinder also and the tool locating device is connected.After car post frock is installed on the frock seat, utilize high pressure cylinder to promote that the fastening positioning device occurrence positions moves and with the locking of tool locating device together, because car post frock is fixed on the tool locating device, so this frock securing means can effectively prevent to produce displacement between car post frock and the frock seat, cause machining error to increase.
The processing method of a kind of secondary bearing entity combination holder support of the present invention compared with prior art, the beneficial effect that is produced is:
1) technological process is simple and quality of processing is high, precision is high.To be installed on the discoidal car post frock with the pillar stock that prior art is made, the two ends of pillar stock spill, before two ends completion of processing with the pillar stock, maintain static between pillar stock and the car post frock, the pillar stock wherein an end face is processed finish after, after the whole upset of car post frock, the other end of reprocessing pillar stock has reduced error.In this course of working, cutter head is unidirectional contacts with processing for the pillar stock, but not milling machine adds the two-way contact of the to-and-fro motion in man-hour, and the contact stress equal and opposite in direction between cutter head and the pillar stock has effectively reduced error;
2) the automaticity height has reduced labor intensity.The fixedly employing pressurized gas of car post frock on the frock seat utilize high pressure control valve automation control, and the error of both having avoided manual control to cause enlarges, and has also reduced labor intensity simultaneously effectively.
3) adopt the milling machine frock processing technique of prior art every every day can only process pillar about 120 jin; And adopt lathe in machining technology of the present invention every every day can process pillar about 327 jin.
4) the milling machine frock processing technique of employing prior art, the length dimension deviation of its pillar is between the 10-40 silk, and tenon left and right sides side-play amount is about 20, and the palpus perpendicularity is about 15, a palpus length difference is about 30, and tenon flat horizontal surface perpendicularity is about 15; And adopting lathe in machining technology of the present invention, the length dimension Deviation Control of its pillar is within 10; Tenon left and right sides side-play amount within 10, must perpendicularity unanimity, must a length difference in 10.
