Abstract
Coupling system between tool holders and machine tools for crushing machines, wherein the tool (1) comprises a cavity (5) with a protrusion (6) having circular profile with radius R and centre C adapted to be concentrically coupled with a suitable semicircular recess (16) having the same radius R′ on the tool holder (2), said coupling being stabilized by at least one safety element (4), such as, for example, a safety pin placed into suitable through holes formed in the tool and in the tool holder and by a tool protrusion (10) penetrating into a tool holder recess (13), said tool holder recess (13) being opposite to said semicircular recess (16).
Claims14
Coupling system between tool holders and machine tools for crushing machines, wherein the tool comprises:
- a cavity with a protrusion having circular profile with radius and centre adapted to be concentrically coupled with a suitable semicircular recess having the same radius on the tool holder, said coupling system being stabilized by at least one safety element and by a tool protrusion penetrating into a tool holder recess, said tool holder recess being opposite to said semicircular recess, and
- wherein said tool holder comprises a main external curved surface so that the cross section at mid length of said tool holder in a plane substantially perpendicular to the rotation axis of said tool holder has substantially the shape of a portion of a spiral, and wherein said tool comprises an upper surface, said upper surface of said tool substantially forming an extension of said main external curved surface of said tool holder when said tool and said tool holder are coupled.
(canceled)
A coupling structure between a tool holder and a machine tool for use in crushing machines comprising:
- a tool holder having a semicircular recess with a first radius adjacent a tool holder apex portion at a first end of a side surface, the side surface having a second end adjacent a recess formed in said tool holder, the side surface forming a protrusion;
- a main external curved surface extending adjacent the recess;
- a crushing tool having a frontal crushing surface ending in a circular shaped portion having a second radius and an upper curved surface ending in a crushing tool apex portion, the second radius of the crushing tool being equal to the first radius of the tool holder;
- a cavity formed in said crushing tool between the second radius and the crushing tool apex portion adapted to receive the protrusion of said tool holder;
- and
- wherein when said tool holder is coupled to said crushing tool, the circular shaped portion of said crushing tool mates with the semicircular recess of said tool holder, the protrusion of said tool holder mates with the cavity of said crushing tool, and the crushing tool apex portion mates with the recess of said tool holder and a spiral is formed from the upper curved surface of said crushing tool and the main external surface of said tool holder,
- whereby said tool holder and said machine tool are securely coupled and safely kept in place.
