Abstract
Machining process for end-surface hemispheres of miniature shafts includes steps of placing a plurality of machined and sectioned miniature shafts into a grinding machine; adding grinding stones in the grinding machine; grinding the miniature shafts for 10 hours to 20 hours, and screening out machined miniature shafts. The machining process for end-surface hemispheres of miniature shafts has the advantages that the miniature shafts are creatively ground by the grinding machine, a traditional concept that the grinding machine is only used for machining raw edges and burrs of products is broken through, end surfaces of the miniature shafts are ground to be hemispherical by means of creatively properly prolonging grinding machining time, labor and consumables are saved, machining speed of products is increased, the hemispherical end surfaces of the miniature shafts are similar, differences of the hemispherical end surfaces of the different miniature shafts are reduced, and a machining effect is good.
Description
Technical field
The present invention relates to a kind of processing technology of miniature axle, especially a kind of miniature axial end hemisphere processing technology.
Background technology
Miniature axle is less relatively, and precision is high, and some claims accurate axle again, little axle, axle core, armature spindle, pin; Rivet, guide rods etc., main material are the carbon steel of each material, stainless steel, copper, aluminium etc., surface treatment mainly contains zinc-plated; Nickel, blackout, carburizing etc. some industry also requires to do salt spray test, continuous a couple of days non-corrosive. and main manufacturing procedure is for thrusting grinding, surface treatment, turning; Sorting, packing etc. main process equipment has, grinding machine, lathe, measuring truck, tube etc. is thrown in heat treatment.Its purposes is wider, and product all can be used in a lot of industries.Like the rotating shaft in the motor, printer, duplicator, the rotating shaft in the scanner, the guide rod shaft in the CD/DVD CD-ROM drive, the rotating shaft in the auto parts and components etc.Sometimes in order to make miniature axle have installation capability preferably, or otherwise needs, often require miniature shaft end is processed into hemispherical.
Existing miniature shaft end rounding is hemispherical, is to be cut into one section that is fit to length earlier according to product demand, and then it is carried out the rounding at two ends; Its rounding technology generally all is to adopt the mode of ball crusher or Vehicle Processing with its end, two ends rounding, makes its end, two ends form hemispherical, and this technology rounding speed is slow; Need one one miniature axle is processed, human cost is very high, and efficient is extremely low; Not only can cause processing cost to increase, also can incur loss through delay the duration.The hemisphere radius that processes of this technology is prone to bigger error in addition, its shape disunity, nonstandard, and processing effect is poor.
Summary of the invention
The problem that the present invention will solve is to improve that miniature axial end hemisphere processing technology efficient is low in the background technology, cost is high, the problem of processing effect difference.
In order to overcome the above problems; The present invention provides a kind of miniature axial end hemisphere processing technology, comprises following processing step: the miniature axle of a plurality of sections of being processed into is put into grinder, wherein be added with grinding stone in the grinder; After grinding 10h-20h, filter out the miniature axle that processes.
Said grinder is planetary roll cast machine.
Said grinding stone is brown corundum.
Said miniature shaft diameter is less than 2mm, and length is 5 to 30 times of diameter.
Miniature axial end hemisphere processing technology of the present invention, breakthrough use grinder grinds miniature axle, has broken grinder in traditional thinking and just has been used for the burr of treatment product; Creatively through the proper extension attrition process time, make the end surface grinding of miniature axle become hemispherical, compare in the prior art the technology that machines to one one on miniature axle; Have very big improvement, practiced thrift manual work and consumptive material, improved the process velocity of product; Described miniature axial end hemisphere processing technology of the present invention in addition; The hemispherical that processes is standard comparatively, compares processing technology of the prior art, and the hemispherical of each miniature axial end is unified more approaching; Dwindled the hemispheric difference of different miniature axial end, processing effect is good.
The specific embodiment
Be described further in the face of a kind of miniature axial end hemisphere processing technology of the present invention down.
Miniature axial end hemisphere processing technology in the present embodiment, following processing step: the miniature axle of 80,000 sections of being processed into is put into grinder, and the length of said miniature axle is 6 millimeters, and diameter is 0.8 millimeter.Wherein be added with grinding stone in the grinder, behind the grinding 15h, filter out the miniature axle that processes.In the present embodiment, also in process of lapping, add grinding agent, made better effects if in the process of lapping, efficient higher.Miniature axial end hemisphere processing technology in the present embodiment grinds to form fillet with miniature axial end during beginning in process of lapping, along with the prolongation of milling time, gradually fillet is ground greatly, and the fillet of final end face becomes end face and is hemispherical.Milling time confirms that according to characteristics of product and demand the material hardness height such as having just needs the proper extension milling time.In process of lapping, can suspend and observe the grinding situation of miniature axle, adjust milling time according to Different products characteristic and product demand, make miniature axle reach best grinding effect, promptly near hemispheric end face.Certainly, more than the size of miniature axle also can change, the profile shaft diameter is less than 2mm, length is 5 to 30 times of diameter, is the size that relatively is fit to technology of the present invention.
In the present embodiment, said grinder is planetary roll cast machine.Utilize the characteristics of the rolling grinding of planetary roll cast machine, improved processing and efficient, practice thrift process time, in addition, in the present embodiment, said grinding stone is brown corundum.The palm fibre corundum is a handy grinding stone on the market, and its grinding effect is good, and cost is not high, is differential grinding stone of the present invention.
In the present embodiment, said miniature shaft diameter is less than 2mm.Because the more little axle of diameter, needed attrition process is short more, and with the technology that is fit to present embodiment, processing effect is also better, so for the too big axle of diameter, exceed miniature category and be not suitable for this technology.
The invention is not restricted to above embodiment and conversion.
