Abstract
The invention provides a spiral milling cutter for machining a high-precision pocket hole of a bearing retainer, and relates to the technical field of the machining of a high-precision bearing retainer. The spiral milling cutter is characterized in that machining equipment drives the spiral milling cutter to rotate, and can do partial motions such as a linear vertical motion and a circumferential motion, the bearing retainer is fixedly arranged on the machining equipment, and the spiral milling cutter is used for machining the pocket hole of the bearing retainer; the spiral cutter is connected onto a machine tool main shaft of a machining center through a cutter handle; a plurality of spiral cutter edges are arranged under the cutter handle, and the spiral cutter edges surround a cutter body and spirally rise to the part of the cutter handle; and the spiral cutter edges are connected onto the cutter handle, and the accuracy of the angle of a cutter bit is determined according to the taper angles of the tapered pocket holes of different retainers. According to the spiral milling cutter, the pocket hole of the bearing retainer is formed and milled by one step, so that the spiral milling cutter has the characteristics of being high in efficiency, good in quality and high in precision.
Description
Technical field
The present invention relates to high-precision bearing retainer processing technique field, is be used to a kind of moulding screw-on cutter of processing high-accuracy retainer pocket hole concretely.
Background technology
Retainer is one of bearing four large parts, is used for the high-precision bearings such as space flight, Digit Control Machine Tool, accurate main shaft, precision instrument, and strict especially to the required precision of retainer, the precision of retainer has determined the precision of bearing.Present domestic high-precision bearing 90% depends on state's outer bearing, and the precision techniques that this main cause wherein is domestic machining bearing retainer does not reach product requirement, how to improve the retainer machining accuracy, is the technical barrier of present bearing industry.
According to retainer pocket pore structure characteristics, the crudy in retainer pocket hole has a direct impact with the cutter in processing pocket hole, so need to the process tool of retainer be improved.
Summary of the invention
For the retainer machining accuracy technical problem of domestic existence, the invention solves the technical difficult problem of retainer high accuracy processing, a kind of spiral forming cutter for processing retainer high accuracy pocket hole is provided.
Technical solution of the present invention is: process equipment drives the screw-on cutter rotation, and can do up and down rectilinear motion, circumference equal dividing motion, and retainer is fixed on the process equipment, and screw-on cutter carries out the processing of pocket hole to retainer.Helical tooth blade is connected on the machine tool chief axis of machining center through handle of a knife; Many spiral cutting edges are arranged below handle of a knife, and spiral cutting edge is around tool bodies, and spiral rises to shank portion, and spiral cutting edge can be interrupted milling, better reduces cutting resistance.The mid portion of spiral cutting edge is more prone to chip removal, can not affect because of copper scale the crudy on surface.Many spiral cutting edges be equivalent to much knives man-hour and cut adding, and in the hole milling process, following blade can be born rough cut, and middle blade can be born smooth turning, and top blade can be born smart cutting, finishes the function of precision cutting.Spiral cutting edge is connected on the handle of a knife, and the angle of cutter head is determined accurate angle according to the cone angle in different retainer tapered pockets hole.Described handle of a knife is cone.Described spiral cutting edge is double-sided blade.
The beneficial effect that the present invention has is: the present invention carries out the one-shot forming Milling Process to retainer pocket hole, has the efficient height, and quality is good, the characteristics that precision is high; General domestic ordinary skill, boring twice, pocket hole machining accuracy can only reach more than the Ra3.2um, and the present invention can reach Ra0.8um.The invention solves the technical difficult problem of retainer high accuracy processing, is a kind of new technology with promotional value.
