The support block 3 is mounted and fixed to a mounting base 7. The mounting base 7 is mounted and fixed to a table of the copying machine, so that press notches 7 a and 7 a are provided on both left and right sides and a press taper 7 b is provided at a rear end. FIG. 2) is provided.

FIG. 2 is a cross-sectional view of FIG. 1, which will be described in more detail. Vises 1 and 2 for clamping an exemplary key and an unprocessed key blank are vice supported rotatably. A vice configured to include block main bodies 1A and 2A and vise blocks 1B and 2B movably supported by two shafts 8 and 8 on side surfaces of the vise block main body, and a vice configured to be supported by the shafts 8 and 8. The compression bolts 9, 9 are interposed between the blocks 1B, 2B and the vise block main bodies 1A, 2A to protrude the shaft bolts 10, 10 laterally outward, and the tightening handles 11, 11 are screwed into the shaft bolts. The clamp is performed by moving the vise blocks 1B and 2B.

[0007] In addition, shaft portions 1a and 2a are provided at the rear of the vice block bodies 1A and 2A of the vises 1 and 2 for clamping a key and an unprocessed key blank as examples. The shafts 1a, 2a are supported by a support block 3, stopped by stoppers 12, 12 so as not to fall forward, and connection arms 4, 4 are attached and fixed to the rear shaft ends to connect as shown in FIG. The devices 1 and 2 are connected by a plate 5 so that they are linked in the same direction and at the same angle.

[0008] Scale disks 13, 13 each having a scale for displaying an angle on its circumference are fixedly mounted on the shaft portions 1a, 2a extending behind the vice block main bodies 1A, 2A. Numerals 13 and 13 are buried so as to be substantially flush with the entire surface of the instruction block 3, and cutout windows 3a and 3a are provided on the upper surface of the support block 3 as shown in FIG. When tilted by moving, the tilt angle is displayed. The shaft portions 1a, 2a bearing by the support block 3 are fixed by tightening the stopper bolts 14, 14, and the vice 1, 2 is required. The angle of inclination can be set.

In the vice 1, 2 as described above, positioning grooves 1b, 2b are provided in the clamp portions 1C, 2C shown in FIG. 1, and a positioning plate is fitted into the positioning grooves 1b, 2b. The model key and the key blank unfinished key blank are placed against the tip of the key blank, and the positioning clamp is attached. In the case where the base of the model key and the key blank with no key groove is stepped, the stepped portions are applied to the front surfaces 1c and 2c of the clamp portions of the devices 1 and 2, and the positioning clamp is attached. Is also good.

Next, an embodiment in which the present invention is mounted on a table of a key copying machine and a key is duplicated will be described with reference to FIG. 3. A mounting base of the present invention is mounted on a table 16 of a key copying machine 15. Pressing notches 7a, 7a on both the left and right sides and a taper portion 7b at the rear end are pressed down by pressing members 17, 17 and 18, and attached. A key blank N with no key groove is fastened to the clamp portion of the vice 2 by tightening and clamping the handles 11, 11. The model key M and the key blank N which has not been processed with the keyway are positioned with their tips abutting on the positioning plate 19, and the vises 1 and 2 are inclined in the same direction and at the same angle with respect to the horizontal. , 14 are tightened and set, and the rear connecting portion is covered with a cover 20.

In the key copying machine 15, a copying tool 21 A is attached to a left spindle chuck 21, and a keyway machining tool 22 A is attached to a right spindle chuck 22 and rotated. The operation of the lever 23 raises and lowers the spindle chucks 21 and 22 to raise and lower the tools 21A and 22A. The table 16 is supported on two shafts 24 and moves on a base plate 25 that moves back and forth. The shaft 24 supporting the base board 25 is fixedly mounted on the base board 27. The shaft 24 is supported by two shafts 26, and is supported on both upper sides of a base board 27 which moves left and right. The lever 28 is movable back and forth and left and right.

Then, while rotating the spin chucks 21 and 22, the lever 23 is operated to raise and lower the spindle chucks 21 and 22, and the tip of the copying tool 21A attached to the spindle chuck 21 is moved to the left. Pressing the key groove of the model key M clamped to the clamp portion of the vice 1 and pressing the key blank N which has not been machined into the key groove N clamped to the clamp portion of the right vise 2 While pressing the tip end of the tool 22A to move the handle lever 28, the key groove is machined in the key blank N which has not been subjected to the keyway following the keyway of the key M as the model to duplicate the key.
