A circular saw mounting device which rotatably supports a saw blade in a grinding machine is disclosed. The mounting device comprises a base plate adapted for mounting in a grinding machine; a centering element comprising at least two engagement elements configured to be operated in a radial direction between a mounting position (M) and a locking position (L). According to the invention the mounting device further comprises an actuator comprising a pin being configured to be operated in an axial direction (A) and arranged to engage with pivot articulated couplings to each of the engagement elements to thereby transfer a radial displacement to the at least two engagement elements and to thereby operate the at least two engagement elements between the mounting position (M) and the locking position (L).
A circular saw mounting device (30) which rotatably supports a saw blade (80) in a grinding machine,
A mounting device (30) according to anyone of the preceding claims, wherein the pin (61) is spring-loaded by an elastic means (67) towards a resting position in which the at least two engagement elements (51) are set to the locking position (L).
A mounting device (30) according to anyone of the preceding claims, wherein the mounting device (30) on a first surface (30-1) thereof has a mounting bracket (41) which is arranged for mounting the mounting device (30) in a grinding machine.
A mounting device (30) according to anyone of the preceding claims, wherein each of the at least two engagement elements (51) are formed as segments of a circle, wherein a peripheral outer edge portion of each segment forms an engagement surface (51-1) adapted to radially engage an inner edge (81-1) of a central bore (81) of a saw blade (80).
A mounting device (30) according to anyone of the preceding claims, wherein the mounting device (30) has, on a first surface (30-1) thereof, a centrally arranged dowel (43) having a through axially extending bore (44), and wherein the pin (61) is coaxially received and axially operable inside said bore (44).
A mounting device (30) according to anyone of the preceding claims, wherein the mounting device (30), on a second surface (30-2) opposite the first surface (30-1), comprises a cap (66), said cap (66) being arranged to extend coaxially with the pin (61) and circumferentially surround said pin (61).
A mounting device (30) according to anyone of the preceding claims, wherein the base plate (40) on the second surface (30-2) of the mounting device (30) has, in a peripheral outer section, an engagement surface (45) adapted to engage a side surface (80-1) of a saw blade (80).
