[0033] The technical solutions of this application will be clearly and completely described below with reference to the accompanying drawings of the embodiments. The described embodiments are only some, not all, of the embodiments of this application. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.

[0034] According to one aspect of this application, a brazing auxiliary device is provided for supporting at least two welding fixtures for fixing the workpiece to be welded. Figure 1 A schematic diagram of the brazing auxiliary device according to an embodiment of this application is shown. Figure 2 This paper shows another structural schematic diagram of the brazing auxiliary device according to an embodiment of the present application. Figure 3 A schematic diagram of the structure of the welding fixture for fixing the workpiece to be welded, according to an embodiment of this application, is shown. Exemplarily, the welding fixture 2 can be a metal fixing frame, and the workpiece 3 can be a copper tube in a semiconductor refrigeration device.

[0035] According to the example embodiment, such as Figure 1 , Figure 2 and Figure 3 As shown, the brazing auxiliary device 1 includes a frame 11, a support and limiting member 12, a rotary worktable 13, a cooling assembly 14, and a protective gas supply assembly 15.

[0036] For example, the frame 11 can be a cuboid structure made of metal rods. The support and limiting member 12 can be a cuboid metal piece used to provide support for the rotary table 13. The rotary table is a smooth metal table surface.

[0037] A support limiting member 12 is disposed on the top of the frame 11. A rotary worktable 13 is connected to the support limiting member 12 via a bearing 131, and the rotary worktable 13 supports at least two welding fixtures 2. A cooling assembly 14 is disposed on the frame 11, and the cooling assembly 14 includes a first water tank 141, a liquid suction device 142, and a liquid outlet pipe 143. The first water tank 141 contains coolant and is disposed inside the frame 11. The liquid suction device 142 is disposed inside the first water tank 141. The liquid outlet pipe 143 is disposed corresponding to the welding fixture 2, with one end connected to the liquid suction device 142 and the other end supplying coolant to the workpiece 3 to be welded on the welding fixture 2.

[0038] For example, when a welder uses the brazing aid device 1, the coolant immerses the washing liquid device. Exemplarily, the first water tank 141 is a cuboid with an open top. The first water tank 141 can be made of plastic or metal. The washing liquid device is a water pump. The coolant is water.

[0039] The protective gas supply component 15 is disposed on the rotary worktable 13 and is correspondingly disposed with the welding fixture 2. One end of the protective gas supply component 15 is connected to the external gas source 4, and the other end is connected to the workpiece 3 to be welded, so as to supply protective gas to the workpiece 3.

[0040] For example, the other end of the protective gas supply component 15 is fitted onto the gas inlet of the workpiece 3 to be welded. For example, the protective gas is nitrogen.

[0041] Through the above embodiments, this application integrates the support and limiting components, rotating worktable, cooling components, and protective gas supply components into a frame, achieving the integration of the brazing fixing device's support, cooling, and protective gas supply functions. This significantly simplifies the brazing operator's operation and improves brazing efficiency. The rotating worktable uses bearings to connect the support and limiting components, thereby improving load-bearing stability and supporting continuous multi-station operation. Multiple objects to be welded can be simultaneously placed on the rotating worktable, reducing downtime for changing objects and further improving brazing efficiency.

[0042] Figure 4 A schematic diagram of the structure of a second water tank according to an embodiment of this application is shown. Figure 5 Another structural schematic diagram of the second water tank according to an embodiment of this application is output.

[0043] According to the example embodiment, such as Figure 1 , Figure 4 and Figure 5 As shown, the cooling assembly 14 also includes a second water tank 144. The second water tank 144 has a through hole 1441 that matches the shape of the support limiting member 12. The second water tank 144 is fitted onto the support limiting member 12 through the through hole 1441. The second water tank 144 is used to collect the remaining coolant on the rotary table 13. The second water tank 144 is provided with a return pipe 1442. The outlet of the return pipe 1442 extends into the first water tank 141 to return the remaining coolant on the rotary table 13.

[0044] For example, the second water tank 144 can be a metal tank. The dimensions of the second water tank 144 are larger than the dimensions of the rotary table 13.

[0045] Through the above embodiments, this application reduces the consumption of coolant and thus the cost of brazing by setting up a second water tank to recover the coolant remaining on the workbench and reusing the remaining coolant.

[0046] According to the example embodiment, such as Figure 1 As shown, the sidewall of the second water tank 144 is circular, the rotating worktable 13 is circular, and the diameter of the sidewall of the second water tank 144 is smaller than the diameter of the rotating worktable 13.

[0047] Through the above embodiments, this application reduces the overall footprint of the brazing auxiliary device by limiting both the second water tank and the rotating worktable to be circular. The diameter difference design between the second water tank and the optional worktable avoids mutual interference between the rotating worktable and the second water tank.

[0048] Figure 6 A schematic diagram of a protective gas supply component according to an embodiment of this application is shown. Figure 7 This illustration shows another structural schematic diagram of a protective gas supply component according to an embodiment of this application.

[0049] According to the example embodiment, such as Figure 1 , Figure 6 and Figure 7 As shown, the protective gas supply assembly 15 includes a slip ring 151, a first gas pipe assembly 152, and a second gas pipe assembly 153. The slip ring 151 is fixed to the rotary table 13 and is coaxially arranged with the bearing 131. One end of the first gas pipe assembly 152 is connected to an external gas source 4, and the other end is connected to the slip ring 151. One end of the second gas pipe assembly 153 is connected to the slip ring 151, and the other end is correspondingly arranged with the welding fixture 2 and connected to the workpiece 3 to be welded.

[0050] For example, one end of the first tracheal assembly 152 is a single tracheal tube, and the other end is divided into at least two tracheal tubes, which are simultaneously connected to the air slip ring 151. The second tracheal assembly 153 consists of at least two tracheal tubes corresponding to the first tracheal assembly 152.

[0051] Through the above embodiments, this application achieves the transition connection between the first air pipe assembly and the second air pipe assembly by setting an air slip ring. The first air pipe assembly achieves a static connection through the air slip ring, and does not follow the bearing rotation during the rotation of the rotary table, thereby avoiding the first air pipe assembly from getting tangled together due to rotation, and thus improving the stability of the brazing process.

[0052] According to the example embodiment, such as Figure 6 and Figure 7 As shown, the bearing 131 is located at the center of the rotary table 13, and the second air pipe assembly 153 includes at least two air pipes, each air pipe extending outward from the center of the rotary table 13 to connect to the corresponding workpiece 3 to be welded.

[0053] Through the above embodiments, this application achieves the simultaneous provision of protective gas for multiple objects to be welded by setting the bearing at the center of the rotary table and connecting each gas pipe of the second gas pipe assembly to the corresponding object to be welded, thereby improving the utilization rate of the protective gas.

[0054] According to the example embodiment, the liquid suction device 142 is a water pump, and the liquid outlet pipe 143 is a magnetic universal water outlet pipe.

[0055] For example, the magnetic universal water outlet pipe can be attached to the side wall of the second water tank 144.

[0056] Through the above embodiments, the liquid outlet pipe of this application is a magnetic universal water outlet pipe, which is easy to disassemble and maintain.

[0057] According to the example embodiment, such as Figure 1 As shown, the brazing auxiliary device 1 also includes a moving device 16. The moving device 16 is located at the bottom of the frame 11.

[0058] For example, the mobile device 16 is a swivel wheel.

[0059] Through the above embodiments, this application reduces the difficulty of moving the brazing auxiliary device by setting a moving device at the bottom of the frame.

[0060] According to the example embodiment, such as Figure 2 and Figure 6 As shown, the bearing 131 has a first fixing hole 1311. The support and limiting member 12 has a second fixing hole 121. The bearing 131 is fixed to the support and limiting member 12 through the first fixing hole 1311 and the second fixing hole 121.

[0061] For example, the first fixing hole 1311 and the second fixing hole 121 can be fixed by screws and nuts.

[0062] Through the above embodiments, this application achieves a detachable connection between the bearing and the support limiting member by using screws and nuts, and through the first fixing hole and the second fixing hole.

[0063] According to the example embodiment, such as Figure 1 and Figure 4 As shown, a connector 1443 is provided at the bottom of the second water tank 144, and the connector 1443 is provided with a third fixing hole 14431. The frame 11 is provided with a fourth fixing hole 111. The second water tank 144 is fixed to the frame 11 through the third fixing hole 14431 and the fourth fixing hole 111.

[0064] For example, the third fixing hole 14431 and the fourth fixing hole 111 can be fixed by screws and nuts.

[0065] Through the above embodiments, this application achieves a detachable connection between the second water tank and the frame by using screws and nuts, and through the third and fourth fixing holes.

[0066] According to the example embodiment, such as Figure 2 As shown, the support limiting member 12 is provided with a weight reduction hole 122.

[0067] Through the above embodiments, this application reduces the amount of material consumed in producing the support and limiting component by providing weight-reducing holes in the support and limiting component, thereby reducing the production cost of the brazing auxiliary device.

[0068] Finally, it should be noted that the above description is merely a preferred embodiment of this application and is not intended to limit this application. Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions of the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
