Mechanism with cams for engraving and splitting tiles
View Patent ↗This invention relates to a mechanism for scoring and splitting tiles usable on manual tile cutter machines of the type preferred for cutting extra-thick tiles.
1 . A mechanism for scoring and splitting tiles, comprising:
a main body;
a carriage including a single set of bearings positioned in a single plane; and
a running guide embodied as a single body;
wherein the bearings engage the running guide to mount the carriage on the running guide to be axially movable along the running guide while the bearings maintain an angular orientation of the carriage with respect to the running guide; and
wherein the main body is rotatably mounted to the carriage to be rotatable with respect to the carriage;
a scoring and splitting body, movable relative to the main body;
a movement device providing a pivotal mounting of the scoring and splitting body to the main body allowing the scoring and splitting body to pivot from a scoring position to a splitting position;
wherein the movement device comprises a cam having a first cam portion, a cam follower engaging the first cam portion, and a spring elastically pressing the cam follower against the first cam portion.
2 . The mechanism for scoring and splitting tiles according to claim 1 , wherein at least one of the bearings comprises a housing made of at least partially of flexible material suitable for flexibly housing a pin.
3 . The mechanism for scoring and splitting tiles according to claim 1 , wherein at least one of the bearings comprises an adjustable rigid bearing suitable for housing a pin.
4 . The mechanism for scoring and splitting tiles according to claim 1 , wherein the carriage further includes a second pin comprising thrust bearings suitable for allowing only rotation of the main body on an axis of the second pin.
5 . The mechanism for scoring and splitting tiles according to claim 4 , and further comprising a stop device for stopping the main body relative to the carriage and suitable for interrupting the rotation of the main body.
6 . The mechanism for scoring and splitting tiles according to claim 5 , wherein the stop device comprises at least one interference surface operated by a spring.
7 . The mechanism for scoring and splitting tiles according to claim 6 , wherein the stop device comprises at least one seat as an obstacle for the at least one interference surface.
8 . The mechanism for scoring and splitting tiles according to claim 1 , wherein the scoring and splitting body comprises at least one protection surface and a scoring wheel.
9 . The mechanism for scoring and splitting tiles according to claim 1 , and further comprising a second cam portion which engages the running guide to rotate the scoring and splitting body.
10 . The mechanism for scoring and splitting tiles according to claim 8 , and further comprising a rolling bearing on which the scoring wheel rotates.
11 . The mechanism for scoring and splitting tiles according to claim 10 , and further comprising an anchor mount for mounting the scoring wheel to the scoring and splitting body, the anchor mount including at least one lateral entrance suitable for allowing passage of the rolling bearing.
12 . The mechanism for scoring and splitting tiles according to claim 11 , wherein the anchor mount further includes a shaft, a head, and a stop nut.
13 . The mechanism for scoring and splitting tiles according to claim 8 , and further comprising a guard in contact with the scoring wheel, the guard at least partly made of a low friction material.
14 . The mechanism for scoring and splitting tiles according to claim 1 , wherein the running guide is composed of a single extruded metal profile.
