Description

Technical Field

[0001] The utility model relates to a high-frequency brazing machine, in particular to a turntable-type high-frequency brazing machine. Background Art

[0002] A high-frequency brazing machine is an induction heating device that uses an induced current to heat the workpiece to a certain temperature, melting the solder and thus wetting and bonding two metals of the same or different materials. When the high-frequency brazing machine is operating, workpieces, cleaned with flux (usually a water-soluble flux), are placed close together, and the brazing material is placed near the joint gap or between the joint gaps. When the workpieces and brazing material are heated to a temperature slightly above the brazing material's melting point, the brazing material melts (the workpieces are not melted) and, through capillary action, is drawn into and fills the gap between the solid workpieces. The liquid brazing material and the workpiece metals diffuse and dissolve into each other. After heating is stopped, the workpieces are placed in quicklime or insulating sand to maintain the temperature (for simple tempering of the weld seam). After a period of time, they are removed, and the brazed joint is formed.

[0003] The structure of existing high-frequency brazing machines is usually fixed by welding or bolts. As a result, when the components of the brazing machine age or become damaged after a long period of use, the entire brazing part structure can only be replaced as a whole, which makes maintenance more troublesome and costly. Utility Model Content

[0004] The purpose of the utility model is to provide a turntable high-frequency brazing machine, which has the advantages of simple structure and easy maintenance. It is convenient to disassemble and reassemble parts separately, thereby facilitating subsequent maintenance, reducing maintenance costs, and solving the problems of inconvenient maintenance and high maintenance costs of brazing machines in the prior art.

[0005] To achieve the above-mentioned objectives, the utility model provides the following technical solutions: a turntable-type high-frequency brazing machine, comprising a cabinet and a supporting assembly arranged on the cabinet, a turntable being provided on the supporting assembly, and multiple groups of brazing assemblies being provided on the supporting assembly along the circumferential direction of the turntable, the brazing assembly comprising a bottom support, a fixing pile arranged on the bottom support, a first table, a second table and a bottom step plate, the bottom step plate being fixedly connected to the bottom support, and a accommodating assembly being provided on the bottom step plate, the accommodating assembly comprising a accommodating seat and a side-opening cavity arranged on the accommodating seat, a positioning table being provided below the side-opening cavity, a ventilation groove penetrating the accommodating seat being provided on the positioning table, a fixing assembly being provided on the accommodating assembly, the fixing assembly being used to confine the welding part on the accommodating assembly and to pass inert gas into the welding part through the accommodating assembly, the fixing assembly comprising a ring cap and a connector fixed on the ring cap, the connector being a cavity structure with openings at both ends and a hollow interior.

[0006] Preferably, the support assembly includes a workbench and a turntable support shaft rotatably connected to the workbench, and the workbench is fixed on the cabinet; so that the structure of the workbench remains stable and the workbench is set horizontally.

[0007] Preferably, the workbench and the turntable are coaxially designed and fixedly connected to the turntable, so that the turntable and the brazing assembly thereon can rotate along with the workbench.

[0008] Preferably, the fixing piles are vertically arranged, and there are two fixing piles in total, and the first platform and the second platform are both fixed on the two fixing piles, so that the structures of the first platform and the second platform remain stable.

[0009] Preferably, a middle-step plate is fixed on the first plate, and a top-step plate is fixed on the second plate; the welded parts can be limited by both the middle-step plate and the top-step plate.

[0010] Preferably, two groups of middle-step plates and top-step plates are provided on the bottom support, and the two groups of middle-step plates are symmetrical on both sides of the first platen; so that one group of brazing components can process two welded parts simultaneously.

[0011] Preferably, an outer concave annular groove is provided on the outer circle of the accommodating seat, and two fixing plates are fixedly connected to the top step plate. Both fixing plates enter the outer concave annular groove and are fixedly connected to the accommodating seat; thereby fixing the accommodating seat on the two fixing plates.

[0012] Preferably, the fixing assembly further comprises a fixing plate fixed to the outer side of the ring cap, and two limiting grooves are provided in the circumferential direction of the fixing plate;

[0013] Preferably, the two limiting grooves are respectively adapted to the two locking strips, and the two locking strips are symmetrically installed on the accommodating seat; when the two limiting grooves are inserted into the two locking strips, the fixing plate and the accommodating seat can be fixed, so that the accommodating component and the fixing component are combined into one, maintaining the stability of the structure.

[0014] Compared with the prior art, the beneficial effects of the present invention are as follows:

In the fixing assembly, the connection nozzle and the connecting head are modularly installed, the fixing plate and the receiving seat are modularly installed, and in the receiving assembly, the receiving seat and the top step plate are modularly installed. Therefore, it is convenient to disassemble and reinstall the parts separately, so as to facilitate the subsequent maintenance of the parts on the receiving assembly and the fixing assembly separately, making the maintenance work more convenient. During maintenance, only a single part needs to be replaced, thereby reducing the maintenance cost.

[0016] 2. The utility model fixes the welded parts multiple times through the multiple functions of the middle plate, the top plate and the joint nozzle, thereby ensuring that the welded parts will not shake during the brazing process, thus ensuring the stability of its structure;

[0017] 3. Inert gas is introduced from the vent groove into the weld cavity through the vent groove and the connector, ring cap and connection nozzle arranged above the vent groove, so that the weld cavity will not be oxidized due to high temperature during the brazing process, thereby ensuring that the properties of the weld are not affected.
