[0026] Among them, the positioning and rotating rod 26 includes a disassembly and assembly groove 2601 and a rotating groove 2602.

The convex block of the positioning rotating shaft sleeve 17 is used to insert into the disassembly and assembly groove 2601 and enter the rotating groove 2602 to fix the top plate 1 and the bottom plate 2. During the assembly process of the top plate 1 and the bottom plate 2: First, align the convex block of the positioning rotating shaft sleeve 17 with the disassembly and assembly groove 2601 of the positioning and rotating rod 26, and slide the convex block of the positioning rotating shaft sleeve 17 downward along the disassembly and assembly groove 2601, so that the positioning rotating shaft sleeve 17 is sleeved outside the positioning and rotating rod 26, and the convex block enters the rotating groove 2602 of the positioning and rotating rod 26 to fix the top plate 1 and the bottom plate 2. When the top plate 1 is manually rotated, the top plate 1 drives the positioning rotating shaft sleeve 17 and the convex block to rotate, and the convex block rotates in the rotating groove 2602. During disassembly, rotate the convex block to below the disassembly and assembly groove 2601 and vertically align it with the disassembly and assembly groove 2601, and pull out the convex block upward along the disassembly and assembly groove 2601 to disassemble and separate the top plate 1 and the bottom plate 2.

[0027] Among them, the contact and conductive mechanism includes a first circular backing plate 13, an outer contact conductive bead 14, an inner contact conductive bead 15 and an insulating circular pad 16. The first circular backing plate 13 is provided at the middle part of the bottom of the top plate 1. The insulating circular pad 16 is embedded in the first circular backing plate 13. The outer contact conductive bead 14 and the inner contact conductive bead 15 are embedded in the top of the insulating circular pad 16. The outer contact conductive bead 14 and the inner contact conductive bead 15 are composed of a cylindrical shell, a spring assembly and a ball. The spring assembly and the ball are arranged in the cylindrical shell, and the spring assembly presses the ball so that the ball is exposed.

[0028] Among them, the contact conductive mechanism includes a second circular backing plate 23, an outer conductive ring 24, an inner conductive ring 25, and an insulating washer 28. The second circular backing plate 23 is provided on the top of the bottom plate 2. The positioning rotating rod 26 is arranged in the middle of the second circular backing plate 23 and fixed by bolts. The insulating washer 28 is provided on the top of the second circular backing plate 23, and the outer conductive ring 24 and the inner conductive ring 25 are provided on the insulating washer 28. After the top plate 1 and the bottom plate 2 are installed, the outer contact conductive beads 14 and the inner contact conductive beads 15 are in contact with the outer conductive ring 24 and the inner conductive ring 25. At the same time, the balls of the bull's-eye universal balls 22 are in contact with the pulley grooves 12. Place the flat milling key machine, vertical milling key machine, and fully automatic key machine on the top plate 1. The top power cables 19 respectively pass through the three power holes 101 and are connected to the flat milling key machine, vertical milling key machine, and fully automatic key machine. The other ends of the top power cables 19 are respectively connected to the outer contact conductive beads 14 and the inner contact conductive beads 15. The other end of the bottom power cable 27 is connected to the power supply line. The power is introduced into the outer conductive ring 24 and the inner conductive ring 25 through the bottom power cable 27. Since the outer contact conductive beads 14 and the inner contact conductive beads 15 are in contact with the outer conductive ring 24 and the inner conductive ring 25, the power enters the flat milling key machine, vertical milling key machine, and fully automatic key machine along the top power cables 19 respectively, realizing the power supply for the flat milling key machine, vertical milling key machine, and fully automatic key machine. The key matching staff can clamp the first key in the automatic key matching machine, input the tooth number, and after key matching processing, take out the first key, then clamp the second key on the automatic key matching machine and continue to work. At this time, the top plate 1 can be manually rotated, so that the top plate 1 drives the outer contact conductive beads 14 and the inner contact conductive beads 15 to roll and contact and rotate on the outer conductive ring 24 and the inner conductive ring 25. During the rotation, the contact conductive beads of the outer contact conductive beads 14 and the inner contact conductive beads 15 are squeezed, so that the contact conductive beads contract inward and squeeze the spring assembly, and then the top plate 1 drives the outer contact conductive beads 14 and the inner contact conductive beads 15 to roll and conduct electricity on the outer conductive ring 24 and the inner conductive ring 25. At the same time, the pulley grooves 12 of the top plate 1 slide on the balls of several bull's-eye universal balls 22, which is convenient for the key matching staff to rotate the top plate 1. The automatic key matching machine is rotated away through the top plate 1, and the flat milling key machine is rotated in front of the key matching staff. Clamp the master key and the key blank on the flat milling key machine, and process the key blank through the flat milling key machine and the master key. At this time, since the outer contact conductive beads 14 and the inner contact conductive beads 15 rotate in contact on the outer conductive ring 24 and the inner conductive ring 25, during the rotation process, the automatic key matching machine can keep working normally to process the second key. At this time, the second key was previously clamped in the automatic key matching machine, and at this time it is also completed. As the top plate 1 continues to rotate, the vertical milling key machine on the top plate 1 is rotated in front of the key matching staff to perform the third processing on the first key and the second key, so that the three key matching machines continue to work during the rotation of the top plate 1, thereby improving the key matching work efficiency.Moreover, the bottom power cord 27 and the top power cord 19 are set as two or three wires. When there are three wires, one of them is a grounding protection wire. The grounding protection wire of the bottom power cord 27 is connected to the bull's-eye universal ball 22 and the positioning rotating rod 26 on the bottom plate 2. One end of the grounding protection wire of the top power cord 19 is connected to the pulley groove 12 and the positioning rotating shaft sleeve 17 on the top plate 1, and the other end of the grounding protection wire of the top power cord 19 is connected to the shell of the key duplicating machine. The grounding protection effect is achieved through the contact conduction between the bull's-eye universal ball 22 and the pulley groove 12 and between the positioning rotating rod 26 and the positioning rotating shaft sleeve 17.

[0029] Among them, the top plate 1 includes a power supply hole 101, a top dust-proof ring 11, and a top power cord 19. A plurality of power supply holes 101 are formed on the top plate 1. The top power cord 19 is used to pass through the power supply holes 101 and is respectively connected to the outer contact conductive bead 14 and the inner contact conductive bead 15. A top dust-proof ring 11 is provided on the periphery of the top plate 1 near the pulley groove 12.

A plurality of bull's-eye universal balls 22 are further provided between the bottom dust-proof ring 21 and the second circular backing plate 23 on the bottom plate 2. The bottom power cord 27 is also respectively connected to the outer conductive ring 24 and the inner conductive ring 25. The dust-proof effect is achieved through the mutual cooperation of the top dust-proof ring 11 and the bottom dust-proof ring 21.

[0031] Among them, the positioning mechanism includes a positioning plate 18, a fixing hole 1801, and a positioning hole 1802. A plurality of positioning plates 18 are provided at the four corners of the bottom of the top plate 1. A fixing hole 1801 is formed on the top wall of the positioning plate 18, and a positioning hole 1802 is formed in the lower part of the side wall of the positioning plate 18. The positioning plate 18 is fixed to the top plate 1 by screwing a bolt into the fixing hole 1801 of the positioning plate 18 and into the top plate 1.

[0032] Among them, the positioning mechanism includes an electromagnet positioning pin 3, an electromagnetic power cord 31, and a switch 32. An electromagnet positioning pin 3 is provided at one of the four corners of the bottom plate 2. The electromagnet positioning pin 3 is connected to an electromagnetic power cord 31. The electromagnetic power cord 31 consists of two power cords. One power cord is connected to the outer conductive ring 24, and the other power cord is connected to one end of the switch 32. The other end power cord of the switch 32 is connected to the inner conductive ring 25. The electromagnet positioning pin 3 includes a positioning rod. The positioning rod of the electromagnet positioning pin 3 is used to cooperate with the positioning hole 1802 to fix the top plate 1 in position; the positioning rod of the electromagnet positioning pin 3 is used to pass through the positioning hole 1802 to fix the top plate 1 in position. The electromagnet positioning pin 3 includes a bracket, a spring assembly, an insulating sleeve, a positioning rod (iron core), an electromagnet coil, etc.; and the positioning plate 18 is provided with a positioning hole 1802, which is an arc surface with inclined surfaces on both sides. The key-making staff rotates the top plate 1 to drive the positioning plate 18 to rotate. The inclined surfaces on both sides of the positioning plate 18 are in contact with the round head part of the positioning rod of the electromagnet positioning pin 3. As the top plate 1 continues to rotate, it squeezes the positioning rod of the electromagnet positioning pin 3 to move backward in the insulating sleeve and squeeze the spring assembly outside the insulating sleeve. When the positioning hole 1802 of the positioning plate 18 rotates to the front of the electromagnet positioning pin 3, the spring assembly drives the positioning rod of the electromagnet positioning pin 3 to move forward by its own elasticity, so that the head of the positioning rod is stuck into the positioning hole 1802 of the positioning plate 18 to fix and position the top plate 1; when the top plate 1 needs to be rotated next time; since the switch 32 controls the electromagnet positioning pin 3, when the outer conductive ring 24 and the inner conductive ring 25 are powered on, the key-making staff manually presses the switch 32, and the electromagnet coil of the electromagnet positioning pin 3 is powered on, generating a magnetic force to attract the positioning rod (iron core) and pull it out of the positioning hole 1802 of the positioning plate 18.
