Abstract
The invention discloses a method for measuring axial positions of seal grooves of rings of deep groove ball bearings. The method includes machining a standard part of a measuring ring at first; setting an aligning point on the standard part; and measuring the axial position of a seal groove according to measured data of the standard part. The method has the advantages that the method can be used for measuring the axial position of the seal groove without position and dimension conversion or influence of discretion deviation of height dimensions or an expensive profile meter; and particularly, the method can be reused by means of machining different standard parts of measuring rings for the seal grooves in batch machining procedures during actual production, and accordingly is economical and practical.
Description
Technical field
The present invention relates to a kind of measuring method, especially a kind of deep ditch ball bearing ring seal groove axial location measuring method.
Background technology
The enclosed deep ditch ball bearing ring can be good at lubricating, to arrive high-revolving purpose, lasso will be processed seal groove in process, the finished product lasso adopts rubber seal or dust cap to seal, wherein the axial location size of seal groove directly has influence on the assembling of seal, is the very crucial size of enclosed deep ditch ball bearing ring.
The dimensional measurement of known seal groove axial location is to adopt seal groove position model, is of a size of basis, seal groove inwall to the size of same end face with fore shaft.Yet, for another kind of seal groove shape, as Fig. 1, can see that the seal groove position dimension is labeled as take seal groove design circle D as the basis, the seal groove inwall is to the size a of other end.Seal groove design circular diameter and fore shaft diameter are not identical, if adopt same measuring method, need the dislocation size, are subject to the impact of height dimension scattered error after the position dimension conversion, can not well satisfy deviser's intention.Even if adopt contourgraph can be competent at the measurement of seal groove geomery, but the contourgraph somewhat expensive, and in actual production process, especially in the batch machining process, good application can not be arranged, uneconomical.
In sum, adopt existing measuring method can't well satisfy the requirement of layout design.
Summary of the invention
In order to overcome the limitation in background technology, the invention discloses a kind of deep ditch ball bearing ring seal groove location measurement method, the method is simple and easy, is convenient to adjust, operate; The self check of convenient operation work and checker patrol and examine, and can be good at controlling this type of seal groove position, and efficient are high, economical and practical.
The technical solution adopted for the present invention to solve the technical problems is: a kind of deep ditch ball bearing ring seal groove axial location measuring method, comprise the following steps: (1) processing seal groove measurement ring standard component, on measurement ring standard component, measurement point is set, is the his-and-hers watches point; (2) the 0.01mm round meter is arranged on height-gauge, measures the ring standard component and be placed on the test desk of height-gauge, adjust the height-gauge V-arrangement fork of below, the his-and-hers watches point of 0.01mm round meter table point standard component pointed; (3) adjustment round meter indicator to 0 indicating value position, and fix round meter.(4) take out measurement ring standard component, place deep groove ball bearing to test desk, 0.01mm round meter table point is placed on the seal groove inwall, rotate a circle, the minimum and maximum indicating value of reading instrument.(5) get with the height value of standard component and, get and after value be maximum, the minimum value of seal groove position.
It is the outside dimension of bearing ring that seal groove of the present invention is measured ring standard component outside dimension, and internal diameter size is the internal diameter size of bearing ring, and height dimension is the seal groove position dimension.
The his-and-hers watches point that arranges on measurement ring standard component of the present invention be take the standard component center as the center of circle, take seal groove design circular diameter as the annulus of diameter on a bit.
The invention has the beneficial effects as follows, mensuration for the difform seal groove axial location of deep ditch ball bearing ring, do not need the dislocation size, can not be subject to the impact of height dimension scattered error, nor with the contourgraph somewhat expensive that adopts somewhat expensive, and in actual production process, especially in the batch machining process, measure the processing of ring standard room by seal groove, can repeatedly reuse, economical and practical.

(2) the 0.01mm round meter is arranged on height-gauge, measures the ring standard component and be placed on the test desk of height-gauge, adjust the height-gauge V-arrangement fork of below, the measurement point of 0.01mm round meter table point standard component pointed;
(3) adjustment round meter indicator to 0 indicating value position, and fix round meter;
(4) take out measurement ring standard component, place deep groove ball bearing to test desk, 0.01mm round meter table point is placed on the seal groove inwall, rotate a circle, the minimum and maximum indicating value of reading instrument, 1.+0.02(max), + 0.01(min), 2.-0.01(max) ,-0.03(min);
(5) get with the height value of standard component and, get and after value be maximum, the minimum value of seal groove position, 1. 31.42mm(max), 31.41mm(min), position relative datum value 31.4mm is large for seal groove, means that seal groove is shallow, 2.-0.01mm(max),-0.03mm(min), position relative datum value 31.4mm is little for seal groove, means depth of sealing groove.
