A transformer is arranged on the left side of a rack, a water outlet valve is arranged on the right side of the rack, a water outlet pipe is disposed on the lower side of the water outlet valve, a water inlet valve is arranged on the left side of the water outlet valve, a water inlet pipe is arranged on the lower side of the water inlet valve, the lower end of the water outlet pipe is connected with a water return pipe of an electrode holder, the lower end of the water inlet pipe is connected with the water inlet pipe of the electrode holder, a delayed pressure regulating valve is arranged on the outer side of the transformer, a one-way valve is disposed on the left side of the delayed pressure regulating valve, an outage delayed electromagnetic valve is arranged on the left side of the one-way valve, and the lower end of a slave pipe is connected with the delayed pressure regulating valve and downwards connected with the electrode holder through the one-way valve and the outage delayed electromagnetic valve. The suspension type spot welding machine is simple in structure, reasonable in design, low in process cost, and capable of obviously improving welding quality.
Description
technical field [0001] The invention relates to a welding device, in particular to a suspension type spot welding machine which prolongs the time for maintaining welding pressure. Background technique [0002] Suspension spot welding machine is an important equipment in vehicle processing and production. A complete car body has at least 4,000 welding spots. The quality of welding is directly related to the stability and driving safety of the vehicle. At present, when the spot welding machines sold and used on the market leave the factory, the pneumatic action program has been edited and set. However, in actual operation and use, due to the influence of materials, temperature, equipment and other factors, the aging of the solder joints due to condensation and cooling is not enough, resulting in cracks and shrinkage cavities in the weld joints. Contents of the invention [0003] The purpose of the present invention is to overcome the above-mentioned defects, to provide a su...
