在成批大量生产中,采用浮标式气动量仪和简单弹性单爪测量装置,在普通磨床上实行主动测量,把废品防止在发生之前,具有良好的效果。但齿轮内孔多数为单键孔和花键孔,由于触头占据内孔很大空间,必然使砂轮直径大为减小,因而限制了一般浮标式气动量仪和单爪测量装置的推广使用。针对上述情况,我厂于1975年开始,经过一年的反复试验,终于试成“后置式单爪触头自动测量装置”。对齿轮2级精度的圆孔、单键孔、花键孔
In bulk mass production, the use of buoy pneumatic measuring instrument and a single simple elastic single-claw measuring device, the implementation of the initiative in ordinary grinder measurements to prevent waste before it occurs, with good results. However, most of the gear holes are single keyhole and spline hole. Since the contact occupies a large space in the inner hole, the diameter of the grinding wheel will inevitably be greatly reduced, thus limiting the general use of general buoyant pneumatic gauges and single-claw measuring devices . In response to the above situation, our factory began in 1975, after a year of repeated tests, finally try into a “post-single-claw automatic contact measuring device.” 2-level precision gear round hole, keyhole, spline hole
