[0040] The top right side of the right table plate 7 is fixed with an adjusting air cylinder 24, the extension end of the adjusting air cylinder 24 penetrates into the inner side of the guide vice body 16, the adjusting air cylinder 24 can finely adjust the position of the guide vice body 16, adapt to the clamping demand of workpieces of different specifications, enhance the equipment applicability, and improve the equipment adjustment efficiency and operation convenience.

[0041] The bottom of the sliding plate 1 and the right table plate 7 is fixed with a cooling liquid joint 25, the arrangement of the cooling liquid joint 25 can realize rapid cooling during the welding process, improve the welding efficiency and workpiece quality, and the cooling system is designed in an integrated manner with the main body structure, so as to enhance the overall stability and service life of the equipment.

[0042] In the application, the induction cylinder 17 drives the two clamping jaws 18 to move oppositely or reversely, so as to realize clamping and releasing of the blade or alloy head; when the clamping jaw 18 clamps the workpiece, the orthodontic forceps 5 in the clamping groove 4 and the forceps body positioning mold 6 form a positioning cooperation, so as to ensure that the welding position of the blade or alloy head and the orthodontic forceps 5 is accurately aligned; the guide vice body 16 drives the induction cylinder 17 and the clamping jaw 18 to move synchronously, so as to adapt to the welding positioning requirements of workpieces of different specifications.

[0044] In the application, the protective gas introduced by the connector body 19 diffuses in the closed space formed by the floating gas sealing cover 9 and the fixed gas sealing cover 2; the air hole 23 provides a channel for gas flow, discharges the air in the closed space, and makes the protective gas uniformly cover the welding area; the protective gas continuously fills the closed space, maintains the gas protection environment in the welding process, and reduces the oxidation of the weld.

[0045] Working principle: the operator places the orthodontic forceps 5 to be welded in the clamping groove 4 of the clamping table 3, and makes one end of the orthodontic forceps 5 abut against the forceps body positioning mold 6; the clamping assembly is moved to the temperature control assembly by the closing cylinder 22 between the sliding plate 1 and the right base plate 7, so that the fixed gas sealing cover 2 and the floating gas sealing cover 9 are in abutment and closed, the pressing cylinder 21 is pressed downward by the pressing cylinder 20 in the floating gas sealing cover 9, so as to prevent the blade from being displaced during the welding process;

[0047] The heat-conducting pipe inside the adjustable supporting leg 11 and the heating soldering piece 13 on the top form a high-frequency induction heating system, and the heat-conducting pipe arranged inside the adjustable supporting leg 11 is a high-efficiency heat-conducting element. The inside of the heat-conducting pipe is a vacuum sealed structure, and is filled with an appropriate amount of working fluid. During the soldering process, the high-frequency induction heat generated by the heating soldering piece 13 is rapidly transmitted to the evaporation section of the heat-conducting pipe, so that the working fluid is instantaneously vaporized. The steam flows to the condensation section under the action of pressure difference, that is, close to the welding contact area, and condenses into liquid after releasing latent heat, and then returns to the evaporation section, forming a continuous and efficient heat transfer cycle. The welding area rapidly reaches the brazing temperature, greatly shortening the welding period. Through efficient heat conduction, local overheating or excessive temperature gradient is avoided, and uniform weld structure and reduced thermal stress are ensured. After starting the high-frequency machine, the alternating magnetic field generates eddy current inside the workpiece, realizing local rapid heating and melting of the solder. The induction air cylinder 17 drives the clamping jaw 18 to automatically right and clamp the alloy head or blade, ensuring that it is aligned with the welding position of the pliers body. The adjusting air cylinder 24 can fine-tune the position of the guide vice body 16 to adapt to different specifications of workpieces.

The closing air cylinder 22 is reset, the clamping assembly and the temperature control assembly are separated, the operator takes out the orthodontic pliers 5 after welding, and the work flow is completed.

[0049] Second embodiment

[0050] In the first embodiment, although the pressing cylinder 20 can drive the pressing rod 21 to press the blade downward, so that the blade avoids displacement during the welding process, metal debris or small impurities may be attached to the end of the pressing rod 21 close to the blade during the welding process, so that the end of the pressing rod 21 away from the pressing cylinder 20 cannot form a horizontal contact surface. Therefore, after the pressing rod 21 contacts the surface of the blade, the blade will be tilted or warped, which will affect the welding quality of the blade. Based on this, the following improvement scheme is made:
