An automatic detection device for bearing dimensional accuracy

Abstract

The invention discloses an automatic detection device of dimensional accuracy of a bearing. A bearing measuring instrument can not meet the detection requirement for volume production. A roundness measuring mechanism comprises a roundness measuring servo motor, a roundness measuring ball lead screw, a roundness measuring sliding block, a rotary knob, an upper roundness measuring jaw, a lower roundness measuring jaw and a roundness measuring sensor. A flatness measuring mechanism comprises a flatness measuring servo motor, a flatness measuring ball lead screw, a clamp flange, a flatness measuring sliding rail, a flatness measuring sliding block and a flatness measuring sensor. An inner and outer diameter and taper measuring mechanism comprises a bearing clamp, a first inner and outer diameter and taper measuring servo motor, a second inner and outer diameter and taper measuring servo motor, a third inner and outer diameter and taper measuring servo motor, a first inner and outer diameter and taper measuring ball lead screw, a second inner and outer diameter and taper measuring ball lead screw, an ejector rod, an inner and outer diameter and taper measuring sliding block, a sliding frame, a third inner and outer diameter and taper measuring ball lead screw and a probe needle. The automatic detection device can achieve full-automatic site on-line measuring of the bearing.

Description

technical field [0001] The invention belongs to the technical field of testing, and relates to a bearing detection device, in particular to an automatic detection device for bearing dimension accuracy. Background technique [0002] With the gradual increase of the output of my country's bearing manufacturing industry, the requirements for the geometric dimension accuracy of bearings, especially the inner diameter, outer diameter, roundness and flatness, are getting higher and higher. Evaluating bearing geometric dimension accuracy is one of the most important methods to distinguish the quality of bearing performance. At present, my country's national standard GB and the machinery industry standard JB have revised the evaluation criteria for the dimensional accuracy of bearings. In the bearing industry, torsion spring dial gauges and bearing measuring instruments for testing bearing inner diameter, outer diameter, taper, roundness or flatness have been widely used, but torsi...

Problems solved by technology

Foreign research in this area is earlier, but it is still in the laboratory stage, and domestic research has just started. Therefore, there is an urgent need for a multi-functional automatic detection that can detect the inner diameter, outer diameter, taper, roundness and flatness of the bearing. system
