A key cutting machine comprises a drilling head (9) for drilling away portions of a key held on a mounting device (3). The mounting device (3) is part of a rotating assembly (6) which is successively indexed to present circumferentially spaced apart portions of the key blank to the drilling device (9). Each index position has associated therewith a control block assembly (61)which, in cooperation with a sensor (92) defines the cutting depth at that index position. Each control block assembly (61) includes means defining a plurality of different cutting depths, each cutting depth having associated therewith indicia whereby the cutting depth of each control block assembly may be selected at will.

Le lecteur optique de profils décrit, qui est destiné en particulier à être utilisé dans des machines à fabriquer des doubles de clefs, se caractérise en ce qu'il comprend: un photoémetteur (16) placé d'un côté du profil (11) à lire; un photodétecteur (21) faisant face au photoémetteur (16) et disposé de l'autre côté du profil à lire; un circuit électronique commandé par le signal de sortie du photodétecteur (21) et comprenant un circuit discriminateur de seuil (25) réglé sur une valeur comprise entre les valeurs correspondant à l'état d'éclairage maximum et à l'état d'éclairage minimum du photodétecteur (21); ainsi qu'un organe mécanique (5, 8) servant à entraîner un mouvement du profil (11) devant être lu par le photodétecteur (21) dans un sens orthogonal à la direction du faisceau lumineux incident heurtant le profil, ledit organe mécanique étant commandé par le circuit discriminateur de seuil (25).

First and second cutter head assemblies each include a key follower positioned at a first elevation and a spaced apart cutting wheel positioned at a second elevation. The key followers trace the bitted surfaces of a master key while the cutting wheels move with the key followers and duplicate bitted surfaces of the master key onto a key blank. A linear displacement bearing assembly is coupled to the first and second cutter heads to permit the key followers and cutting wheels to be laterally displaced with respect to the master key and key blank. A key positioning cassette system holds and aligns the master key and key blank relative to the first and second cutter head assemblies. Another linear displacement device is coupled to the base of the key cutting machine and to the cassette system for longitudinally displacing the key blank and the master key with respect to the longitudinally fixed key followers and cutting wheels. The various elements of the key cutting machine thus trace or follow the bitted surfaces of the master key and duplicate those bitted surfaces onto the bitted surfaces of the key blank.

A key duplicating machine, particularly for bitted keys, comprising, for the original key and for the blank key respectively, two clamps mounted on a carriage mobile horizontally in all directions about a confronting cutter unit in which there are provided two feelers arranged to sense the notches present in the edges of the bit of the original key and two cutters arranged to reproduce these notches in the corresponding edges of the bit of the blank key. The machine comprises a cross-table (20) on which the clamps (24, 25) for the two keys are mounted, this table being slidable along horizontal parallel guides (33) supported at their ends by two pairs of parallel connecting rods (34) and being mobile horizontally in all directions under the control of a horizontal lever (44), and further characterised in that the cutter unit (2) is mobile vertically through a distance at least corresponding to the maximum vertical travel of said cross-table (20) in moving orthogonal to said parallel guides (33).
摘要:
An apparatus for coding or duplicating a pattern of bits onto a key blank employs a locator block (50) which forms reference slots (56, 58, 60) for receiving a key to be duplicated. A template (64) having a matrix of openings (72, 74, 76) which correspond to possible pre-established bit locations is positioned in registration with the key receiving slots (56, 58, 60). A depth gauge (120) is employed so that a guide or sensor (102) selectively seated in a dimple of the pattern key indicates the correct incremental depth of the bit to be duplicated. A cutter (112) having a pre-established relationship to the depth gauge guide (102) is employed to obtain the correct cutting depths for the key blank bits.

A key blank dispensing system (10) comprising a magazine (32) for receiving a plurality of key blanks (14, 22) stacked vertically one above each other in a substantially identical alignment to each other. A slot (34) is provided at the lower end in use of the magazine (32) to enable a single key blank (14, 22) to be ejected laterally from the lower end of the stack of key blanks (14, 22). An ejector arrangement (56) is also provided to urge the lowermost key blank (14, 22) laterally from the stack of key blanks (14, 22).
摘要:
An apparatus for machining a key comprising: i) a self-centring vice (2) for the key in turn comprising a first jaw (21) and a second jaw (22) which cooperate to hold the key in position; ii) a means (3) for shaping the profile of the key. The first jaw (21) comprises a first and a second face (211, 212) for positioning the key which respectively identify a first and a second reciprocally transverse imaginary plane; the second jaw (22) comprising a first and a second face (221, 222) for positioning the key which respectively identify a third and a fourth reciprocally transverse imaginary plane. The first and second jaws (21, 22) can be moved simultaneously nearer along a first direction (4) which forms a non-zero acute angle with the first, second, third and fourth imaginary planes.
