4.3. The essence of the device.

Obtaining a given technical result during the operation of the device is ensured by the location of the nodes, their connection, the relationship in the work.

The copy milling machine for making keys consists of an electric motor (1) mounted on the base (16), a pulley {2) mounted on the shaft, a housing (5) located on the base (16), and a milling shaft (6) mounted on the rolling bearings ), on it, in turn, a pulley (4) is installed, which is driven into rotation by a V-belt (3). A cutter 7 is mounted on the shaft (6) by means of a nut with a left-hand thread (26). On the basis of (16), a fixed platform (32) is installed, in the guides of which there are rolling elements (35), on which a movable platform (17) is installed with its own guides. The movable (17) and fixed (32) platforms are pulled together with the screed assembly along an axis perpendicular to the planes of the platforms (17.32) and equipped with its own rolling guides (34), the central axis (36) in the form of a pin, an elastic element (37) , nut (38). On the movable platform (17) there are racks (14), on the sliding bushings of which are located the axis (ZO) of the clamping device assembly (10). The latter contains clamping caps 6 (9), connected to the assembly (10) by axes (12) and pressing bolts (13); moreover, the original key is installed in the copier area, and the workpiece is installed in the cutter area. The necessary movements of the clamping device assembly (10) are carried out using handles (15). An elastic chip guard (27) is attached to the pad (17). At the base of the machine (16) there is also a copier holder (21), its guides (22), indicator stand (23). A copier (18) is attached to the copier holder (21) with a bolt (19) and a nut (28). The copier holder (21) is attracted to the base (16) using a screw lock (20). The indicator (24) is kept from moving on the stand (23) with the screw (29).

The device operates as follows:

First, the copier (18) is set to a position that ensures the accuracy of copying, as follows. In the direction along its axis, using gaskets between the copier (18) and the copier holder (21). In the direction perpendicular to its axis, by rotation of the handle (25) of the screw drive, followed by fixing with a screw lock (20). After that, the original key is installed in the copier area (18) and the workpiece in the cutter area (7) on the clamping device assembly (10). The key and the workpiece are pressed with clamping caps (9) by means of bolts (13). Next, using the handles (15), the platform (17) is allocated, and, therefore, the clamping unit (10) from the milling cutter (7)

and the electric motor (1) is turned on, which drives the mill (7) through the shaft (6) by means of a pulley (2), a belt (3) and a pulley (4). Then, using the handles (15), the movable platform (17) and the clamping unit (10) located on it with the original key and the workpiece, respectively, approach the original key to the copier (18), and the workpiece to the cutter (7), carefully cutting into the cutter (7) ) into the workpiece, with the copier (18) passing in succession all the protrusions and depressions of the original key using the reciprocating movement and rotation of the clamping device assembly (10) by means of handles (15). - In this case, all the movements of the original key relative to the copier (18) are repeated by the blank relative to the cutter (7), as a result of which the cutter (7) cuts off all the excess from the blank and the blank becomes a duplicate of the key.

5. Discreet applicability

The manufacture of keys on this device is universal and provides stability in terms of accuracy of the milling cutter on the workpiece in accordance with the original, short time for various changes, elimination of backlash due to wear during operation.

When a key of the Abloy type (51) and a key (52) are installed in a zashichny fixture, an emphasis (39) is applied. If the key has different diameters (5-3) in length, then gasket (40) is used during installation. In the manufacture of safe keys with a working

- 8 parts larger than the standard - 20 mm (47) uses a gasket (41) and a clamp (42).

When processing the end face of the key (48), a gasket (43) and a clamp (44) are used.

In the manufacture of flat keys such as English (49), a clamping device is used, consisting of a base (45), which is attached to the clamping unit} and the upper clamp (46).

All devices are installed in pairs: both turnkey and under the workpiece.
