A grinding machine (10) for grinding tools (100; 100') comprises a support unit (11) configured to support a tool (100; 100') to be ground and provided with members suitable to incline it by certain angle (a) with respect to a horizontal reference plane (12); and an operating unit (13) that is mobile along a main axis of development (X) of the grinding machine (10) in order to move with respect to the support unit (11) and comprises abrasive means (14) intended to abrade at least a portion to be ground (101; 101a, 101b) of the tool (100; 100'). The grinding machine (10) comprises adjustment means (15) to adjust the inclination of the support unit (1 1) with respect to the reference plane (12). The adjustment means (15) are mobile parallel to the main axis of development (X) to move to a predetermined distance (D) from the reference plane (12).
B24B 41/06 - Work supports, e.g. adjustable steadies
B24B 3/00 - Sharpening cutting edges, e.g. of toolsAccessories therefor, e.g. for holding the tools
B23Q 3/04 - Devices holding, supporting, or positioning, work or tools, of a kind normally removable from the machine for mounting on a work-table, tool-slide, or analogous part adjustable in inclination
B23Q 1/52 - Movable or adjustable work or tool supports using particular mechanisms with rotating pairs only a single rotating pair
Connection hinge (1) for spectacles frames (100) of the type adapted to connect the lateral sidearm (102) of a spectacles frame (100) to the front part (101) of the same spectacles frame (100); the connection hinge (1) being characterized by comprising: a cup-shaped body (2), which is structured so as to be fixed cantilevered in a rigid manner onto the lateral side of the front part (101) of a spectacles frame (100), and is provided with a central cavity (3) of substantially cylindrical shape and with a transversal, oblong, pass-through slot or cut (5), which extends along the lateral side of the cup-shaped body (2) while remaining on a lying plane locally substantially perpendicular to the reference axis (C) of the central cavity (3), and penetrates in the cup-shaped body (2) up to said central recess (3); a central pin (4) which has a cylindrical shape substantially complementary to that of the central cavity (3) of the cup-shaped body (2), and is inserted in axially rotatable, manner in the central cavity (3) of the cup-shaped body (2); and a transverse locking plug (6) which has an end (6a) rigidly fixed to the body of the central pin (4), and is structured so as to protrude cantilevered from the cup-shaped body (2) engaging in pass-through and sliding manner the pass-through slot or cut (5) present on the lateral side of the cup-shaped body (2), and to be rigidly fixed or incorporated on the proximal end of the lateral sidearm (102) of the spectacles.
Device to detect force so as to optimize the functions of a high-speed punching machine (1 1) having command means (15) able to selectively command the displacement of an actuation member (12) toward a piece (16) to be punched, applying a determinate actuation force (F), a tool-carrier ( 18) disposed removably between the actuation member (12) and the piece to be punched (16) and comprising a containing body (19) in which at least a punch (20) and at least a hammer (22) associated with the punch (20) are mounted axially sliding, so that the latter can selectively move axially between an inactive position and a working position, in order to punch the piece (16) when it is actuated by the hammer (22). At least one force sensor (25, 35, 45, 55, 65) is associated with the hammer (22), to detect the actual force (FW) applied by the punch to the piece ( 16), wherein the actual force (F W) is equal to the resultant of the actuation force (F) minus the mechanical resistances (RM) which affect said punch (20).
