The water cooling system is mainly composed of water cooling pipes or water cooling plates. The welding of the water nozzle joints at both ends of the water cooling pipe is mainly divided into high-frequency brazing and tunnel gas shielded brazing. Due to the advantages of high-frequency welding such as fast welding speed and small heat-affected area, most cooling pipe products choose high-frequency welding. In order to ensure product quality and safety, the high-frequency welding of water cooling pipes requires the design of a corresponding welding base to position the cooling pipe and cool the base itself.
[0003] The existing welding base of the water-cooling pipe is fixed on the frame of the high-frequency welding machine and cannot be automatically raised or lowered. It can only be used to weld cooling pipes with regular water nozzle shapes. When welding cooling pipes with special-shaped water nozzles, loading and unloading is very inconvenient. The high-frequency induction welding ring needs to be lifted before it can be placed in the fixed tooling. Not only is the efficiency low, but frequent movement of the high-frequency induction welding ring makes it difficult to maintain the appropriate position of the welding ring, affecting the welding quality. Poor welding such as overburning or welds may occur, and there is also a certain degree of danger. Utility Model Content

[0023] like Figure 1-Figure 5 As shown, an automatic lifting base for high-frequency brazing includes a high-frequency welding machine assembly 1, a fixed seat 2 is fixedly connected to the high-frequency welding machine assembly 1, a lifting cylinder 3 is fixedly connected to the bottom of the fixed seat 2, the output end of the lifting cylinder 3 passes through the fixed seat 2 and is fixedly connected to a mounting plate 4, a cooling plate 5 is fixedly connected to the top of the mounting plate 4, a cooling groove 501 passing through both sides is opened inside the cooling plate 5, a positioning seat 6 is fixedly connected to the top of the cooling plate 5, four groups of bolts 601 are arranged in a rectangular array on the top of the positioning seat 6, the four groups of bolts 601 pass through the positioning seat 6 and are threadedly connected to the cooling plate 5, and a positioning groove 7 is opened on the top of the positioning seat 6.
[0024] Four groups of rectangular array guide rods 301 are fixedly connected to the bottom of the mounting plate 4 , and guide sleeves 201 corresponding to the four groups of guide rods 301 are fixedly connected to the fixing seat 2 , and the guide rods 301 slide inside the guide sleeves 201 .
[0025] like Figure 5 As shown, a limiting pad 8 is fixedly connected to the inner corner of the positioning groove 7, and the shape of the limiting pad 8 matches the special shape of the corner of the faucet, thereby improving the stability of the faucet being inserted into the positioning groove 7.
[0026] like Figure 1 and Figure 4As shown, a cavity 502 is provided inside the cooling plate 5 mentioned above, and the cavity 502 is communicated with the cooling groove 501. A plurality of groups of heat-conducting rods 9 are fixedly connected to the bottom of the positioning seat 6, and the plurality of groups of heat-conducting rods 9 all penetrate the cooling plate 5 and extend into the cavity 502, and are communicated with the inlet and outlet pipes of the coolant through the two ends of the cooling groove 501. Then, during welding, the coolant is added into the cooling groove 501, and the coolant flows into the cavity 502 through the cooling groove 501. The high temperature generated during the welding of the positioning seat 6 is cooled by temperature conduction, so as to avoid damage to the water nozzles and the cold pipes after multiple welding when they are taken out.

After the welding is completed, the lifting cylinder 3 is started to move downward, and the lifting cylinder 3 drives the positioning seat 6 to move downward through the mounting plate 4 and the cooling plate 5, so that the water nozzle is separated from the positioning groove 7 on the positioning seat 6 to complete the welding.
