Abstract
The invention relates to the technical field of a processing tool for a bearing part, which is provided with an arc trapezoid hole, of an upper cover of a high-precision bearing retainer, in particular to a step forming milling cutter for the arc trapezoid hole of the bearing retainer. A workpiece to be processed is fixed on a processing center working table; a cutter handle of the milling cutter is fixed on a processing center spindle; the cutter handle of the milling cutter is connected with a blade; the blade is provided with an R0.5 chamfered edge, an R1 chamfered edge, a symmetrical small arc edge, an asymmetric large arc edge and a 45-degree chamfered edge; and the R0.5 chamfered edge, the R1 chamfered edge, the symmetrical small arc edge, the asymmetric large arc edge and the 45-degree chamfered edge are sequentially and fixedly connected. The step forming milling cutter has the benefits that the step forming milling cutter solves the technical problem of processing the shape of a complex pocket of the bearing retainer; the pocket is integrally formed; dimensional tolerance and geometric tolerance of the pocket are ensured; the quality of the bearing retainer reaches the world advanced level; various standard requirements for fit precision of the upper cover of the bearing retainer are met; and the step forming milling cutter is simple to operate, is convenient to manufacture, is low in cost, has high applicable values and can be popularized to the bearing industry for use.
Description
Technical fieldThe present invention relates to the machining tool technical field of cover strip radian trapezoidal hole bearing parts on a kind of high-precision bearing retainer, specifically the trapezoidal radian of retainer hole ladder profile milling cutter.
Background technologyThe structure precision of the retainer of leading global enterprise requires high, and mechanism is very complicated, shape is special, a kind of retainer loam cake is wherein arranged, need to process the different mating holes of radian, this halving hole, cooperate with retainer pedestal column boss, five equilibrium is poor to require 0.05 millimeter, and the shape in pocket hole is seen figure, four camber line junctions, must pour out the different fillet of R1 and R0.5, four camber lines are in different size, and shape is different, wherein two is symmetrical little arc, and two is asymmetric large arc; Each radian number of these products is different, and radian, spacing, the wide size in hole etc. have strict requirement, all require in 0.05 scope; Every precision that this retainer requires, not only domestic common process technology can't reach processing request.
Summary of the inventionDefective in view of prior art exists the purpose of this invention is to provide the trapezoidal radian of a kind of retainer hole ladder profile milling cutter, can process the qualified retainer part that meets product requirement.
For achieving the above object, the technology used in the present invention solution is: the trapezoidal radian of retainer hole ladder profile milling cutter, workpiece to be processed is fixed on the machining center workbench, milling handle is fixed on the machining center main shaft, milling handle connects blade, described blade is provided with: R0.5 chamfering blades, R1 chamfering blades, symmetrical little arc sword, asymmetric large arc sword, 45 degree chamfering blades, and be fixedly connected sequentially.
The trapezoidal radian of retainer hole ladder profile milling cutter, its beneficial effect is: this ladder gang milling cutter has solved the process technology difficult problem of the complicated pocket hole shape of retainer, one-shot forming has guaranteed the dimensional tolerance form and position tolerance in pocket hole the retainer quality to be reached world-class levels, finish the requirement of retainer loam cake quality of fit all standard, and simple to operate, easy to make, cost is also lower, applied value is high, can be generalized in the bearing industry and uses.
