PURPOSE:To detect the position of a work by allowing a rotary type tool to contact a work, through revolution, when deburring, cutting work, etc. are carried out by the rotary type tool, in an industrial robot, working machine for exclusive use, or MC. CONSTITUTION:A revolution sensor S consists of an approach switch opposed to the teeth of a gear installed onto the shaft of a rotary type tool T, and the number of crossing teeth is converted to the electric signal by the approach switch and input into a counting circuit K, and when a call signal is supplied from a controller Rc, the above-described electric signals is input into a built-in CPU. A rotary type tool T is travelled, through revolution, on a position detection traveling passage previously passage previously memorized in a controller Rc, and said tool is allowed to contact one or several points on a work W. The coordinates of the action point P of the tool is detected by the controller Rc according to the input supplied from the above-described sensor, and the position of the work W is detected. Therefore, no erroneous operation of the sensor due to vibration, etc. is generated, and the need of expensive sensors is avoided, and cost can be markedly cut. |
