[0030] Please refer to the attached Figure 1-5 The purpose of this embodiment is to provide a tool for orthodontic bracket welding, including: an adapter seat 1 and a tool fixture 2, the tool fixture 2 is detachably mounted on the adapter seat 1; the upper clamping handle 21 and the lower clamping handle 22 in the tool fixture 2 are hinged by a torsion spring; the front end of the upper clamping handle 21 is detachably connected to an upper limit block 25, and the front end of the lower clamping handle 22 is detachably connected to a lower limit block 27; the upper limit block 25 and the lower limit block 27 are used to clamp the bracket 3.

[0031] In this embodiment, the bottom of the upper limit block 25 is provided with an upper limit groove 251; the top surface of the lower limit block 27 is provided with a lower limit groove 271. Specifically, the front end of the upper clamping handle 21 is provided with an upper mounting groove 211, and the first upper connecting block 23 is detachably connected to the upper mounting groove 211, the first upper connecting block 23 is detachably connected to the second upper connecting block 24, and the second upper connecting block 24 is detachably connected to the upper limit block 25. The front end of the lower clamping handle 22 is provided with a lower mounting groove 221, and the lower connecting block 26 is detachably connected to the lower limit block 27.

[0032] Among them, the upper limit groove 251 matches the shape of the bracket body 31, and the lower limit groove 271 matches the shape of the net bottom 32, which can better limit the bracket 3. Since the upper limit block 25 and the lower limit block 27 are both detachable connection structures, those skilled in the art only need to make different limit pieces according to different bracket structures. When replacing other brackets 3 for welding, they can be used after unscrewing the screws and replacing the two limit pieces of other brackets 3, saving the cost of making tooling for each bracket 3.

[0033] In this embodiment, the upper clamp handle 21 is provided with a through first positioning hole 212, and the lower clamp handle 22 is provided with a second positioning hole 222. The first upper connecting block 23 is provided with a third limiting hole 231, and the lower connecting block 26 is provided with a fourth limiting hole 261. When the jig 2 is assembled, in order to ensure the relative parallel position of the upper clamp handle 21 and the lower clamp handle 22, the first limiting rod is inserted into the first positioning hole 212 and the second positioning hole 222; and in order to ensure the relative parallel position of the first upper connecting block 23 and the lower connecting block 26 during installation, the second limiting rod is inserted into the third limiting hole 231 and the fourth limiting hole 261; after the jig 2 is assembled, the two limiting rods are taken out.

[0034] It should also be pointed out that a plurality of third grooves 223 are provided on the outer side surface of the lower clamping handle 22, and a fourth groove 224 is provided in the middle of the lower clamping handle 22; a second small magnet 28 is installed in each of the third groove 223 and the fourth groove 224. The adapter 1 includes a connecting seat 11 and a mounting rod 12; wherein a limiting groove 111 is provided on the connecting seat 11, and the lower clamping handle 22 is clamped in the limiting groove 111; a first groove 112 is provided in the middle of the limiting groove 111, and a large magnet 13 is provided in the first groove 112; a connecting groove 113 is provided at the front end of the limiting groove 111; a plurality of second grooves 114 are provided on the outer side wall of the connecting seat 11, and a first small magnet 14 is installed in each of the second grooves 114. The positions of the multiple first small magnets 14 correspond to the positions of the multiple second small magnets 28, generating suction force between them, thereby improving the reliability of the connection between the adapter 1 and the fixture 2; at the same time, the large magnet 13 and the small magnet 14 in the fourth groove 224 attract each other, further improving the reliability of the connection between the adapter 1 and the fixture 2.

[0035] In addition, the end of the mounting rod 12 with a smaller diameter is a threaded rod section 123, which is inserted into the connecting groove 113 and then threadedly connected to the nut 122 to fix the mounting rod 12; a connecting hole 121 is provided on the cylinder at the end of the mounting rod 12 with a larger diameter. The above structure is easy to disassemble and install.

[0036] The welding system using the tooling for orthodontic bracket welding includes a welding machine, an adapter seat 1 is installed on the welding machine, and the welding machine drives the adapter seat 1 to rotate, and the first side, the second side, and the third side of the clamped bracket 3 are respectively aligned with the welding gun for welding. The tooling fixture 2 is driven to rotate by the rotation of the welding machine, and the three sides of the bracket 3 are respectively aligned with the welding gun, so that the three-side welding of the bracket 3 can be completed. The welding process does not require manual flipping of the tooling, which reduces the probability of wrong welding and missed welding.
