Detector for race position of hub bearing outer ring

Abstract

The invention discloses a detector for a race position of a hub bearing outer ring. The detector is characterized in that a datum plate is vertically mounted and fixed on a pedestal; circular holes are formed in the upper ends of the datum plate; a supporting seat is mounted on the vertical datum plate by a fourth bolt; both ends of a first spring thin plate and a second spring thin plate are respectively mounted and fixed at one ends of a first supporting seat and a second supporting seat through fifth bolts; lower parts of a third spring thin plate and a fourth spring thin plate are mounted and fixed at the upper end of the second supporting seat through first screws; the upper parts of the third spring thin plate and the fourth spring thin plate are mounted and fixed at the lower end of a positioning block through second screws; a middle part of a detecting rod is inserted in the circular hole in the upper end of the datum plate in a movable fit manner; the right end of the detecting rod is fixed in the circular hole in the upper end of the positioning block; a steel ball is mounted on the outer circle of the left end of the detecting rod; a stand column is mounted and fixed on the pedestal; a meter rod is mounted and fixed in an end groove of the stand column; a contact of the left end of the meter rod is in contact with the right side of the positioning block, so as to form the online detector for the race position of the hub bearing outer ring.

Description

technical field [0001] The invention relates to a device for detecting the position of the groove of the outer ring of a bearing, in particular to a device for detecting the position of the groove of the outer ring of a wheel hub bearing. Background technique [0002] At present, the detection instruments for the groove position of the hub bearing outer ring mainly include: groove position template, profiler, and bearing measuring instrument. [0003] 1. Groove position template: use the groove position template to measure the position of the outer ring groove of the hub bearing, that is, put the template into the product, and put the arc of the sample into the product channel to visually check whether there is a gap on the end face. The groove position template is easy to operate, but when using the groove position template to measure the product groove position, it can only be judged whether the product groove position is qualified by employee experience and visual inspect...

AI Technical Summary

Problems solved by technology

The groove position template is easy to operate, but when using the groove position template to measure the product groove position, it can only be judged whether the product groove position is qualified by employee experience and visual inspection, and the specific value cannot be measured, and the measurement error is relatively large (wrong than the actual groove position) 0.05-0.1mm), it can only be used as a basis for lathe workers to detect the position of the groove, and cannot be used as a standard for measuring the consistency of the groove position when lathe workers and grinders produce products

[0004] 2. Profile meter, although the profile meter measurement can accurately measure the groove position value of the outer ring of the hub bearing (outer flange), it needs professional measurement personnel to measure, the measuring instrument is expensive, the time is long and the efficiency is low (it takes about 10min data), can only be used for the detection of the first piece or sample, and cannot be measured at any time on the production line

Although the value can be obtained by using the bearing measuring instrument and can guarantee the qualification rate of the subsequent production process, but when the groove diameter and groove curvature of the hub bearing outer ring (outer flange) are different from the size of the sample, and the groove position is the same, The position deviation of the detected groove is relatively large (because the probe can only detect a certain point of the groove, and the position change has relatively many influencing factors), but the actual groove position of the outer ring of the wheel hub bearing should be the same as the sample position, change the program to adjust the groove position, which may lead to waste products in the subsequent process; therefore, the accuracy of this method is not high. In addition, there are certain requirements for the detection skills of employees, and the change of the direction of the probe will also change the value of the groove position measurement. 15S is required for the hub shaft outer ring bearing
