The pressing plate 56 slides between the heat welding blade 53 and the top plate 55, and the compression spring 57 is located between the pressing plate 56 and the top plate 55. One end of a pressure spring 57 is welded on the top plate 55; the other end is welded on the pressing plate 56, so that the pressing plate 56 applies pressure to the edge of the upper kettle body under the action of the pressure spring 57, and the edge of the upper kettle body after melting is better adhered with the edge of the lower kettle body after melting. The width of the pressing plate 56 is larger than that of the heating welding knives 53, and when the two groups of heating welding knives 53 are drawn away from each other and pulled out from the upper edge and the lower edge, the pressing plate 56 can drive the upper edge to press the lower edge.

Referring to fig. 6 and 7, the driving cylinder 51 of the welding mechanism 5 mounted on the upper plate is directly fixed to the upper plate by bolts. The rotating shaft 33 is rotatably sleeved with a fixing ring 7, and the fixing ring 7 is fixedly connected with the blocking rod 132, so that the fixing ring 7 does not rotate synchronously with the rotating shaft 33. The driving cylinder 51 of the other set of welding mechanisms 5 is fixed to the fixing ring 7.

The discharging mechanism 6 comprises a discharging mechanical arm 61 and a discharging conveyor belt 62, the discharging mechanical arm 61 clamps the welded cooling liquid pot from the discharging mechanical arm 32 and places the cooling liquid pot on the discharging conveyor belt 62 to be conveyed to the next working procedure when the discharging mechanical arm 32 rotates the welded cooling liquid pot to the feeding port of the discharging conveyor belt 62.

The implementation principle of the cooling liquid kettle welding device provided by the embodiment of the application is as follows: the rotary platform 3 is provided with four stations (a material receiving station, a buckling station, a welding station and a blanking station), and the upper kettle body is automatically fed through the upper kettle body feeding mechanism 1 and is conveyed to the material receiving station; the lower kettle body is automatically fed through the lower kettle body feeding mechanism 2 and is conveyed to the material receiving station. Then the upper rotary disc 31 and the lower rotary disc 32 rotate to rotate the upper kettle body and the lower kettle body to the buckling station; the telescopic cylinder 36 drives the upper rotary table 31 to descend, and the upper kettle body is automatically positioned and buckled with the lower kettle body under the action of the clamping and rotating mechanism 4. The upper turntable 31 and the lower turntable 32 continue to rotate to move to the welding station after being buckled and are welded by the welding mechanism 5. Finally, the upper rotary disc 31 and the lower rotary disc 32 continue to rotate the welded upper kettle body and lower kettle body to a blanking station, and the blanking manipulator 61 removes the cooling liquid kettle from the lower rotary disc 32, places the cooling liquid kettle on the blanking conveyor belt 62 and conveys the cooling liquid kettle to the next station.

The whole process is that the upper rotary disc 31 and the lower rotary disc 32 are welded and processed to form a cooling liquid kettle once every time, and simultaneously the upper kettle body and the lower kettle body are positioned and buckled under the action of the clamping rotary mechanism 4, so that the time difference generated by manual positioning and installation is reduced in the whole process, and the production efficiency is further improved.

The foregoing are all preferred embodiments of the present application, and are not intended to limit the scope of the present application in any way, therefore: all equivalent changes in structure, shape and principle of this application should be covered in the protection scope of this application.
