車研削面の位置検出装置に関し、さらに詳細に
は、上下一対のといし車間から工作物を排出する
ための排出用ガイド板のガイド面と、上記といし
車の研削面との段差を検出する装置に関する。[Detailed description of the invention] [Industrial application field] This invention relates to a position detection device for the grinding surface of a grinding wheel in a vertical shaft double-head surface grinder. The present invention relates to a device for detecting a level difference between a guide surface of a discharge guide plate and a grinding surface of the grinding wheel.

記加工面とガイド面との相対的位置を適正な段差
に調整する必要があつた。
For example, in a vertical shaft double-head surface grinding machine in which the grinding wheel is arranged vertically, when replacing jigs such as the grinding wheel, or when a workpiece is ejected from between a pair of grinding wheels, the grinding wheel If scratches (sag) occur on the machined surface of the workpiece because the level difference between the ground surface of the machine and the guide surface of the discharge guide plate is not appropriate, adjust the relative position of the machined surface and the guide surface to the appropriate level difference. It was necessary to make adjustments.

ガイド面との段差を測定して、この段差が適正値
になるように、上下両といし車を各々といし軸方
向（上下方向）へ移動調整するか、または、排出
用ガイド板の上下方向位置を調整していた。 The conventional method for adjusting this level difference is to first stop the rotation of the grinding wheel, and then use a feeler gauge etc. to measure the level difference between the grinding surface of the grinding wheel and the guide surface of the discharge guide plate. Then, in order to bring this level difference to an appropriate value, the upper and lower grinding wheels were moved in the direction of the wheel axis (vertical direction), or the vertical position of the discharge guide plate was adjusted.

段差を測定しながら段差調整を行つているのが実
状であつた。 These adjustment operations are described in the document "Processing Data File" Volume 6 published by the Japan Machinery Promotion Association Technology Research Institute.
As can be seen from 00010300-02, there is no conventional detection device that detects the level difference, and the actual situation is that the worker measures the level difference while adjusting the level difference.

整を行わなければならず、これに費やす手間や時
間のロスも無視できない。 However, with this level difference adjustment method, when machining workpieces in continuous operation, by the time it is found that scratches (sag) due to the level difference have occurred on the machined surface of the workpiece after machining, the expected number of workpieces have already been machined. In many cases, these products become defective, and workers have to measure and adjust the level difference each time, and the effort and time spent on this cannot be ignored. .
