Abstract
The invention discloses a technical improvement for processing extra-large bearing straight pocket cage rivet hole, relating to the technical field of machining. The technical improvement is characterized by changing the traditional working procedure of processing a straight pocket cage rivet hole, and adopting the order of firstly drilling a rivet hole and then processing a pocket. Therefore, after the rivet hole is drilled firstly, the wall thickness of the cage is greatly greater than the wall thickness the firstly processed pocket in the traditional method, and then the problem that the rivet hole is out of tolerance due to too-thin wall thickness is avoided.
Description
Technical field
The present invention relates to the Machining Technology field, is the process modification of the straight pocket of extra large size bearing hole retainer rivet hole processing concretely.
Background technology
In traditional machining,, generally all be after earlier retainer pocket hole being machined, to bore rivet hole again for the processing technology of retainer rivet hole.This processing mode, the retainer for the processing ordinary construction can satisfy production requirement fully.But for the straight pocket of processing oversize hole retainer, especially thin retainer, various quality problems often appear easily.It is main because the super-huge or straight pocket of thin hole retainer is after processing retainer pocket hole; The entity part of retainer tails off; The contraction distortion of retainer own produces, and the wall thickness between retainer pocket hole is very thin simultaneously, if on this part, bore rivet hole again; At this moment bigger contraction distortion will take place in retainer, and the perpendicularity of product, tapering, size all change a lot.And the dimensional requirement of rivet hole is very strict, and after deforming, the joint distance of center circle at its position degree and rivet hole place will be overproof.
Summary of the invention
In view of the defective that prior art exists, the purpose of this invention is to provide the process modification of the straight pocket of extra large size bearing hole retainer rivet hole processing of the heart distance of a kind of position degree that guarantees rivet hole and place pitch circle thereof.
For realizing above-mentioned purpose; The present invention solves through following technical scheme: the process modification of the straight pocket of extra large size bearing hole retainer rivet hole processing; Be characterised in that the operation that has changed the straight pocket of traditional processing hole retainer rivet hole, adopt the subdrilling rivet hole, the order in processing pocket hole, back.Like this, after the intact rivet hole of subdrilling, the wall thickness of retainer is wanted to process the wall thickness in pocket hole earlier greater than the past from far away, and then has avoided because the too thin overproof problem of rivet hole that causes of wall thickness takes place.
Process modification of the present invention meets actual requirement more, has well guaranteed the position degree of rivet hole, and the heart distance of place pitch circle.This kind processing mode is equally applicable to other manufacture fields.
The specific embodiment
The process modification of the straight pocket of extra large size bearing hole retainer rivet hole processing is characterised in that the operation that has changed the straight pocket of traditional processing hole retainer rivet hole, adopts the subdrilling rivet hole, the order in processing pocket hole, back.Like this, after the intact rivet hole of subdrilling, the wall thickness of retainer is wanted to process the wall thickness in pocket hole earlier greater than the past from far away, and then has avoided because the too thin overproof problem of rivet hole that causes of wall thickness takes place.
