Abstract
A key manufacturing machine utilizing a drilling assembly adapted to perform a drilling operations including a rotating assembly having a number of attaching block assemblies circumferentially spaced at its top portion. Each of the attaching block assemblies has a setting wheel which includes an integral wheel part and a shaft part, and which is turnable to set a desired position. A number of set screws are each disposed within a corresponding threaded hole on the wheel part of the attaching block assembly to be adjustable to respective depths. A sensing device is utilized to sense the depth of each set screw for controlling the drilling depth during the drilling operation.
Claims2
A key manufacturing machine utilizing a drilling means (9) adapted to facilitate drilling operations, said key manufacturing machine comprising:
- a rotating means (6) having a plurality of attaching block assemblies (61) circumferentially spaced at a top portion thereof and a transmission gear (63) at a lower portion thereof, said rotating means (6) having a center-bore portion and being rotatable relative to a stationary bottom block (71) on a pair of bearings (62) disposed therebetween, said block assembly (61) being sensed by a sensing device (92) for controlling a drilling depth during said drilling operation;
- a base block (1) being fixedly disposed on said top portion of said rotating means (6) and being semi-cylindrically shaped to form a cavity (11) therealong;
- a guiding plate (2) being attached to a top end of said base block (1) and having a pin (21) protruding downward and a plurality of longitudinal through-holes (22) disposed circumferentially thereon relative to said pin (21);
- a mounting means (4) being received within said center-bore portion of said rotating means (6) to allow longitudinal movement relative to said rotating means (6) and to prevent relative rotation therebetween;
- a positioning block (3) being rotatably secured on a top end of said mounting means (4) by an adjustable stud (34), an arc slot (33) being disposed on said positioning block (3) to facilitate a rotation of said positioning block (3) relative to said mounting means (4), said positioning block having a center-bored portion to form a bearing surface (31) for supporting a key and having a traverse groove (32) for positioning the key;
- a pair of adjusting blocks (41, 42) being connected between a bottom end of said mounting means (4) and a guide screw (44) driven by of a gas cylinder (46) to set a height of said positioning block (3);
- and
- a transmission means (8) being provided to engage with said transmission gear (63) on said rotating means (6) for facilitating a semi-automatic machining operation.
