Abstract
The invention discloses a large-small pressing foot switching device which comprises a base. The base is provided with a circular hole for mounting of a drill bit. A switching plate, a transmission plate, an air cylinder, a first sensor and a second sensor are further included. The switching plate comprises a large pressing foot and a small pressing foot. The working positions of the large pressing foot and the small pressing foot are placed at the center of the circular hole of the base. The air cylinder, the first sensor and the second sensor are fixed on the base. The transmission plate is fixedly connected with a piston rod of the air cylinder. One end of the transmission plate is fixedly connected with the switching plate. The air cylinder drives the switching plate to move on the surface of the base through the transmission plate, so that a large pressing foot or a small pressing foot moves to a working position, and accordingly switching of the large pressing foot and the small pressing foot is achieved. When the large pressing foot or the small pressing foot moves to the working position, the other end of the transmission plate is sensed by the first sensor or the second sensor, and then the air cylinder is controlled. According to the large-small pressing foot switching device, switching of the large pressing foot and the small pressing foot can be carried out accurately, and hole drilling efficiency is improved.
