Preferably, a plurality of heat exchange fins are arranged on the side surface of the lower electrode head in the cooling box.

Preferably, the heat exchange fins are horizontally arranged.

Preferably, the lower drainage pipe and the lower water inlet pipe are connected with the cooling box from the side.

Preferably, the lower water inlet pipe is communicated with the lower part of the lower cavity.

Compared with the prior art, the beneficial effects are that:

the utility model discloses utilize the shorter lower electrode tip of length to reduce the space that water cooling plant occupy to make spot welder adaptation to the welding of the outer machine of air conditioner, be convenient for establish welding on the electrode tip under with narrow and small object card, utilize the cooling box to lower electrode tip inside and outside simultaneously cool down simultaneously, reach good cooling effect, avoid less because of the space of cavity down, lead to heat transfer area little and lead to the cooling effect not good.

Detailed Description

The present invention will be further described with reference to specific embodiments, as shown in fig. 1 to 3: a novel cooling circulating water loop of a spot welding machine comprises a spot welding machine body 1 and a water cooling device, wherein the water cooling device comprises a water tank 2, a circulating pump, a water outlet pipe and a water return pipe, the water cooling device is arranged on the spot welding machine body 1,

the water outlet pipe is connected with an upper water inlet pipe 3 and a lower water inlet pipe 4, the water return pipe is connected with an upper water outlet pipe 5 and a lower water outlet pipe 6, the upper water inlet pipe 3, the lower water inlet pipe 4, the upper water outlet pipe 5 and the lower water outlet pipe 6 are hoses, the spot welding machine body 1 comprises an upper electrode head 7 and a lower electrode head 8, the length of the lower electrode head 8 is one third of that of the upper electrode head 7, the lower electrode head 8 is lower in length, and narrow articles can be conveniently sleeved on the lower electrode head 8, so that the spot welding machine is suitable for welding smaller articles,

an upper cavity 9 is arranged inside the upper electrode head 7, the upper cavity 9 is communicated with the upper water inlet pipe 3 and the upper water outlet pipe 5, a lower cavity 10 is arranged inside the lower electrode head 8, water in the water tank 2 enters the upper cavity 9 through the upper water inlet pipe 3 under the action of the circulating pump, the water entering the upper cavity 9 is discharged from the upper water outlet pipe 5, the water exchanges heat in the upper cavity 9, thereby cooling the upper electrode head 7 and avoiding the over-high temperature of the upper electrode head 7,

lower electrode tip 8 lower extreme outside cover is equipped with cooling box 11, cooling box 11 and lower drain pipe 6 intercommunication, lower inlet tube 4 extends to in cooling box 11 and communicates with cavity 10 down, export 13 has been seted up to cavity 10 down, lower inlet tube 4 and cavity 10 lower part intercommunication down, export 13 sets up cavity 10 upper portion down, lower inlet tube 4 is carried water down in cavity 10 down, water flows into in cooling box 11 from export 13, the outside of electrode tip 8 is cooled down in the heat transfer, lower electrode tip 8 side inside cooling box 11 is provided with a plurality of heat transfer fins 12, heat transfer fins 12 level sets up, heat transfer fins 12 has improved the heat transfer area between water and the lower electrode tip 8, the efficiency of heat transfer is improved, utilize the outside of lower cavity 10 and lower electrode tip 8, all carry out the heat transfer to the both sides of lower electrode tip 8, the efficiency of heat transfer is improved, lower drain pipe 6 and lower inlet tube 4 are connected with cooling box 11 from the side, the length of electrode tip 8 about the vertical direction has been reduced.

The specific working process is as follows: when needs weld, start the circulating pump, the circulating pump is intake 3 and lower inlet tube 4 with the rivers of water tank 2 in, intake 3 and lower inlet tube 4 get into upper cavity 9 and lower cavity 10 respectively, cool off last electrode head 7 and lower electrode tip 8 respectively, rivers are gone into drain pipe 5 and drain pipe 6 and all flow back to water tank 2 in, take away the heat of going up electrode head 7 and lower electrode tip 8, play refrigerated effect.

The above embodiments are only preferred embodiments of the present invention, and the protection scope of the present invention cannot be limited thereby, and any insubstantial changes and substitutions made by those skilled in the art based on the present invention are all within the protection scope of the present invention.
