Abstract
The invention discloses a method for machining a separated type outer ring of a small and medium-sized thin-wall crossed cylindrical roller turntable bearing. According to the method, the outer ring of the bearing is machined integrally and is lathed to form two half bodies; and the method comprises the following steps of: a, lathing, namely lathing the outer ring integrally, calculating the allowance of an end face and a roller path according to the size of the outer ring, connecting the two half outer rings partially, lathing the middles of the insides of the two half outer rings to form cutting grooves, and leaving cut-off guiding openings on outer diameters; b, drilling and performing heat treatment, namely drilling the outer ring integrally before performing the heat treatment, and performing the heat treatment integrally after drilling; c, grinding, namely in the processes of initial grinding, performing initial grinding on the outer ring integrally without cutting the outer ring off; before final grinding, performing hard lathing to cut the outer ring off along the cut-off guiding openings on the outer diameters, and marking assorted marks; and polishing a cut-off surface, and connecting the upper half outer ring and the lower half outer ring by using a connecting hole to form an integral outer ring, and performing final grinding. By the method, the problems of high deformation possibility during machining and difficulty in guaranteeing concentricity after assembly are solved.
Description
Technical field
The present invention relates to the technology of bearing, relate generally to the split type outer ring processing method of a kind of middle-size and small-size thin-walled crossing cylinder roller turntable bearing.
Background technology
The middle-size and small-size thin-walled crossing cylinder roller turntable bearing of outside dimension D≤500, design form is various, a kind of robot bearing is arranged because handling characteristics; Wall thickness is thinner, is thought of as arming rolling element consent during design more, and the outer ring is for dividing body structure; There is not the button of ending butt joint, the integral quenching form.This structural advantages is: a, can select more cheap bearing steel for use; B, gain in strength; C, be easy to the assembling.But also there is certain drawback: a in this kind structure, because axially thin easy deformation after the split of outer ring, difficulty of processing is bigger; B, because of the outer ring for dividing a body structure, be not easy after the assembling to keep with one heart.
Produce to drawback a that reason is mainly wall thickness and thickness is all thinner.This is due to the product structure feature.
Produce former therefore 1 to drawback b: there is the gap in connection holes; Former therefore 2: the heat-treated deformation effect, because product design requires integral quenching, so all boring processing join before must quenching and bore completion, if split heat treatment, the connection holes of two semi outer rings is out of shape inconsistently easily up and down, causes hole dislocation etc.
Summary of the invention
This patent purpose provides the split type outer ring processing method of a kind of middle-size and small-size thin-walled crossing cylinder roller turntable bearing, is used to solve the yielding and concentric problem of the difficult assurance in assembling back of processing.
The present invention can adopt following technical scheme to realize: described bearing outer ring adopts first integral body to process that car is disconnected to be the processing method of halved body again, and the processing method process is following:
A: turning processing technology: the outer ring is with the integral form Vehicle Processing, and at first the size according to the outer ring calculates end face and raceway allowance, and two semi outer rings are only done the part connection simultaneously, and the bosom car goes out to cut off groove, and external diameter stays to cut off and draws mouth, so that hard car cuts off.
B: boring and Technology for Heating Processing: integral body is holed before the heat treatment of outer ring, and boring back integral body is heat-treated.
C: grinding technique: during each operation of preliminary grinding, the outer ring wouldn't cut off, and integral body is carried out, and is easy to like this to process and the assurance of precision; Before the mill, draw a mouthful hard car along the external diameter cut-out and cut off and carry out supporting mark eventually; The section reconditioning; Behind the good section of reconditioning, look for contraposition postpone along mark line, sheet centering about locating hole is packed pin into, and use connection holes will connect up and down for carrying out whole grinder preface behind the whole circle, can guarantee status requirement and each item required precision of raceway so preferably.
That the present invention is mainly used in is processing thin-walled, arming rolling element consent, outer ring be for dividing body structure, not having the button of ending butt joint, the middle-size and small-size crossing cylinder roller of integral quenching form turntable bearing processing technology.Patent art adopts whole Vehicle Processing and the processing of part mill; Product strength was strengthened; Be beneficial to the assurance of Vehicle Processing and mill machining accuracy again; Realize the uniformity of boring and the uniformity of heat treatment deformation simultaneously, accelerated the product process, solved the yielding and outer ring of processing and be difficult for problems such as concentric.
