Abstract
The utility model discloses a contact-type device for grinding wheel wear automatic detection and compensation. The contact-type device for grinding wheel wear automatic detection and compensation consists of a support, a revolving shaft, a bearing, a lock block, a swinging rod, a probe, a micro switch and a mounting plate. The support is fixed on the mounting plate and provided with a bearing seat. The revolving shaft is supported by the bearing. The lock block is fixed on the revolving shaft and fixedly connected with the swinging rod. The probe is installed at the lower end of the swinging rod. The micro switch is fixed on the mounting plate. The grinding wheel advances along the direction of the probe under the control of a controller after the grinding and processing of a workpiece is finished. When the grinding wheel contacts the probe, the swinging rod swings and drives the lock block to swing so that the micro switch is pressed to close and sends out a closing signal. The grinding wheel movement stops immediately at the moment that the controller receives the closing signal. Then the grinding wheel is driven to move in the opposite direction by the controller after the grinding wheel movement stops. Therefore the distance between the grinding wheel and the probe is constant after each detection, and the grinding wheel wear automatic detection and compensation are achieved.
