Circular saw mounting device

A circular saw mounting device which rotatably supports a saw blade in a grinding machine, the circular saw mounting device comprising:

• a base plate that mounts to the grinding machine;
• a centering element that rotates with respect to the base plate via bearings, the centering element comprising at least two engagement elements slidably moveable in a radial direction between a mounting position and a locking position;
• an actuator that includes a pin that when actuated slidably moves in an axial direction;
• at least two articulated couplings coupled to each of the at least two engagement elements at one end and to the pin at an opposite end, the at least two articulated couplings transferring a radial displacement to the at least two engagement elements and to at least two pivot brackets and a transmission cross to slidably move the at least two engagement elements between the mounting position and the locking position;
• and
• a mounting bracket disposed on a first surface of the circular saw mounting device to mount and lock the circular saw mounting device to the grinding machine.
