As shown in FIG. 2, the tool post 20 for processing is fixed to the main body 10 with a fixing screw 210 having a circular insertion hole 200A formed therein, and an insertion hole 200A. Insertion groove 202 is formed in one side wall of the spring 202A and the ball 202B is installed in the insertion groove 202 and the adjustment pin 203 and the spring 203A is installed in the other main wall adjustment pin ( 203 was tipped into the insertion hole 200A.

And the support jaw 204A is provided at the top and the circumferential wall of the cylindrical swivel formed with a plurality of resilient grooves 204B and rotation stop grooves 204C at which the ball 202B and the adjusting pin 203 are fitted at regular intervals, respectively. 204 is inserted into the insertion hole 200A, and a plurality of tool insertion holes 205 are vertically formed in the swivel 204 so that the tool for processing is provided through the spring 206 in each tool insertion hole 205. 207 is fitted, and an E-ring (not shown) is inserted into the fixing groove 207A formed at the bottom of the machining tool 207 so that the machining tool 207 is inserted into the tool insertion hole 205. ), So as not to leave.

Reference numeral 21 denotes a guide tool post, and as shown in FIG. 3, the support boss 210 having an insertion hole 210A is provided on the lifting platform 13 as shown in FIG. A spring 211 is interposed in the support boss 210 to insert the shaft rod 212, and a guide groove 212A is formed vertically in the shaft rod 212, and an end portion of the support boss 210 is guide groove. A screw 212B fitted to 212A is installed to prevent the shaft bar 212 from being separated from the support boss 210.

In addition, a lower end of the shaft 212 is formed with a U-shaped support 212C, and the support disk 214 is provided with a plurality of rotational disks 214 radially provided with a guide screw 215 and an adjustment screw 215 and a nut. 215A is rotatably installed and the support 212C has a spring 216 and a ball 216A and a spring 217 and an adjustment pin 217A installed so that the ball 216A and the adjustment pin 217A rotate. Facing the disk 214, the rotating disk 214 is formed with a plurality of radial grooves 214A and rotation stop grooves 214B into which the balls 216A and the adjusting pin 217A are fitted.

Reference numeral 22 is a workbench, handles 220 and 221 are installed on the workbench 22, and move forward, backward, left and right according to the rotation of the handles 220 and 221, and a duplicate key on the upper surface of the worktable 22. A vise 222 to which the 222A is fixed and a vise 223 to which the original key 223A is fixed are installed.

In the rotating table 204 and the rotating disc 214, the machining tool 207 and the guide tool 213 having the same shape as the team formed on the wall are sequentially installed one by one, and each of the machining tool 207 and the guide is provided. The serial number is indicated on the tool 213.

In the description of the drawings, reference numeral 17A denotes a fixed groove formed in the machining chuck 17 and into which the selected machining tool 207 is fitted, and 208 is a display unit that displays the machining tool 207 selected by the rotating table 204.

The tool changer of the key replicator of the present invention configured as described above has a replica key 222A and 222A on the vise 222 and 223 without rotating the spindle handle 14 as shown in a of FIG. The original key 223A is fixed to each other, and the handles 220 and 221 are rotated so that the duplicate key 222A and the original key 223A are positioned at the bottom of the machining tool 207 and the guide tool 213. To be.

In such a state, the operator pulls the adjustment pin 217 so that the end of the adjustment pin 217 is separated from the rotation stop groove 214B of the rotation disc 214, and in the form of a groove or the like formed on the original key 223A. While rotating the rotating disk 214, one guide tool 213 is selected to position the upper portion of the original key 223A, and then the adjusting pin 217 is released to end the rotation stop groove of the rotating disk 214. The insertion and rotation disk 214 in 214B is not rotated.

At this time, the ball 216A installed on the support (212C) when the rotating disk 214 is rotated by the spring 216 is inserted into and removed from the elastic groove 214A formed in the rotating disk 214, the operator selected The tool 213 can be accurately positioned directly above the original key 223A.

In this way, when one guide tool 213 is selected according to the groove formed in the original key 223A, the operator checks the serial number of the selected guide tool 213,

Pulling the adjustment pin 203 so that the end is separated from the rotation stop groove 204C, and then rotating the swivel 204 while having the same serial number as the guide tool 213 selected at the display position of the display unit 218 When 207 is positioned and selected, and the selection of the machining tool 207 is completed, the adjustment pin 203 is released to prevent the insertion and rotation of the rotary table 204 into the rotation stop groove 204C.

At this time, the ball 202B installed in the insertion groove 202 is held by the spring 202A and the elastic groove 204C formed in the swivel 204 when the swivel 204 rotates, as in the rotation of the rotating disc 214. ), The operator can ensure that the selected machining tool 207 is positioned exactly above the replica key 222A.

In this way, when the operator grasps the spindle handle 14 and rotates the guide tool 213 and the machining tool 207 in the selected state, the eccentric cam according to the rotation of the spindle handle 14 as shown in b of FIG. As the 141 rotates, the platform 13 is lowered by pressing the platform 13, and the rotary shaft bar 16 and the guide tool post 21 installed on the platform 13 are lowered together to rotate the shaft ( The machining tool 207 is fitted into the fixing groove 17A of the machining chuck 17 fixed to the lower part of the base 16, and the end of the guide tool 213 comes into contact with the surface of the original key 223A.

In this state, the operator turns on the power switch (not shown) to drive the driving motor 18, and the rotary shaft rod 16 and the machining chuck 17 rotate according to the driving of the driving motor 18. Thus, the machining tool 207 installed in the machining chuck 17 is rotated.

In such a state, when the spindle 13 is continuously rotated to lower the platform 13, as shown in c of FIG. 1, a team formed at the end of the guide tool 213 is formed on the original key 223A. After being inserted into the groove, the shaft rod 212 overcomes the elastic force of the spring 211, and enters the inside of the support boss 210, the machining tool 207 fitted to the machining chuck 17 is the team of the end of the replica key ( 222A is contacted to form a groove having the same shape as the machining and original key 223A.

In this way, after the machining operation by the selected guide tool 213 and the machining tool 207 is completed, when the operator releases the spindle handle 14, the lifting platform 13 is raised by the elastic force of the spring 15, the rotary shaft The rod 16 and the guide tool post 21 are raised, the machining tool 207 selected at the machining chuck 17 is detached and returned to the initial state shown in a of FIG. By repeating according to the shape of the groove or the like formed in 223A, the replica key 222A having the same shape as the original key 223A is processed.

As described above, the present proposal is configured to rotate the rotary table and the rotating disc at which the machining tool and the guide tool are arranged in an equal angle, so that the tool can be replaced. Since it is not necessary to remove the troublesome work of reassembling the tool, it is possible to change the machining tool and the guide tool very quickly and easily, thereby reducing the duplication time of the key.
