[0032] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0033] See also Figure 1-6 The utility model provides a technical solution: a cooling device for a pulse argon arc welding gun, including a mounting frame 1, a water tank 2, a cooling plate 3, a water pump 4, a processing barrel 5, a top cover 6, a connecting rod 7, an activated carbon plate 8, a filter plate 9, a delivery pipe 10, a telescopic pipe 11, a temperature sensor 12, a cooling cylinder 13, a contact ring 14, a side plate 15, a screw 16, an extrusion plate 17 and a pulse argon arc welding gun body 18, such as Figure 1 As shown, the pulse argon arc welding gun body 18 is installed on the mounting frame 1, and the cooling plate 3, the water pump 4 and the temperature sensor 12 are all connected to the control system, and the cooling plate 3, the water pump 4 and the temperature sensor 12 are controlled by the control system;

[0034] A water tank 2 is mounted on the mounting frame 1. A tank cover is mounted on the top of the water tank 2. The tank cover can be opened to inject cooling water into the water tank 2. The cooling fins 3 installed inside the water tank 2 are connected to an external power supply to reduce the temperature of the water inside the water tank 2 through the cooling fins 3.

[0035] During installation, the cooling cylinder 13 is placed on the outside of the pulse argon arc welding gun body 18. The pulse argon arc welding gun body 18 is located on the inside of the contact ring 14. The vertical center line of the pulse argon arc welding gun body 18 coincides with the vertical center line of the cooling cylinder 13. The cooling cylinder 13 is confined to the outside of the pulse argon arc welding gun body 18 by the clamping mechanism. Figure 1 、 Figure 2 and Figure 3 As shown, the clamping mechanism includes a side plate 15, a screw 16 and an extrusion plate 17. The side plates 15 are fixed to the left and right ends of the lower surface of the cooling cylinder 13, and the inner threads of the side plates 15 are connected to the screw 16. The inner end of the screw 16 is rotatably connected to the extrusion plate 17. When the screw 16 is rotated, the extrusion plate 17 moves inward, so that the inner side surface of the extrusion plate 17 is tightly fitted with the outer side surface of the pulse argon arc welding gun body 18.

[0036] The working principle of the utility model is as follows: turn on the water pump 4 installed above the water tank 2, the water tank 2, the water pump 4, the treatment barrel 5, the delivery pipe 10, the telescopic pipe 11, the cooling cylinder 13 and the contact ring 14 constitute a water circulation mechanism, the input end of the water pump 4 is connected to the water tank 2 through a pipe, and the output end of the water pump 4 is connected to the treatment barrel 5 through a pipe.

The filtering mechanism includes a top cover 6, a connecting rod 7, an activated carbon plate 8 and a filter plate 9. After passing through the activated carbon plate 8 and the filter plate 9, the cooling water flows into the filter plate 9. After being filtered by the filter plate 9, the cooling water flows through the delivery pipe 10 and the telescopic pipe 11 into the cooling water chamber formed by the cooling cylinder 13 and the contact ring 14. Since the contact ring 14 is made of a deformable plastic product, the cooling water enters the contact ring 14, expanding the contact ring 14 so that the contact ring 14 fits the outer surface of the pulse argon arc welding gun body 18. The water in the cooling chamber exchanges heat with the pulse argon arc welding gun body 18, reducing the temperature of the pulse argon arc welding gun body 18. The heat-exchanged water then flows from the telescopic pipe 11 connected to the bottom end of the cooling cylinder 13 to the water tank 2.

[0037] like Figure 1 and Figure 6 As shown, a temperature sensor 12 is installed at the left end of the telescopic tube 11 at the left end of the delivery pipe 10, and the temperature of the cooling water entering the cooling cylinder 13 is monitored by the temperature sensor 12;

[0038] Since the processing barrel 5 is threadedly connected to the top cover 6, the top cover 6, the connecting rod 7, the activated carbon plate 8 and the filter plate 9 can be removed from the processing barrel 5 by rotating the top cover 6, and the activated carbon plate 8 and the filter plate 9 can be cleaned. The above completes a series of operations of the cooling device of the pulse argon arc welding gun.
