Description
Technical field
The utility model relates to a kind of welding equipment, especially relates to a kind of projection welder.
Background technology
At present the welding equipment of body of a motor car nut (bolt) mainly is a fixedly projection welder of three kinds of DN-125, DN-160 and DN-250, the throat opening of these three kinds of welding machines is all smaller, adjustable range is 420---480mm, when the position of nut (bolt) welding hole to the distance of panel beating material during greater than 480mm, above-mentioned three kinds fixedly projection welder can't weld, and fixing projection welder price comparison costliness is generally more than 30,000 yuan.Though the mash welder adjustable range is bigger, its upper/lower electrode is an electrode cap, and schematic diagram shown in Figure 2 can only weld sheet metal component; Also there are some producers that the part that fixing projection welder can't weld is adopted CO
2Weld, and adopt the welding of this mode, (1) can produce the biased difference in hole influence next procedure, and the difficulty of doing over again; (2) be easy to generate phenomenons such as welding slag, rosin joint, influence is assembling normally, safety problem can occur when serious; (3) Han Jie flue dust can influence air quality, pollutes environment.
The utility model content
Technical problem to be solved in the utility model is at the deficiencies in the prior art, to provide distance adjustment scope bigger, the cheap projection welder of the position of a kind of nut (bolt) welding hole to the panel beating material.
For solving the problems of the technologies described above, the technical solution of the utility model is: a kind of projection welder, this projection welder comprise frame, electric part and mechanical part composition, and the control section of regulating the control welding parameter is the microcomputerized control case; Electric part comprises that the projection welding top electrode is with projection welding bottom electrode, transformer and be connected the projection welding top electrode and the cable of projection welding bottom electrode and transformer; Mechanical part comprises soldering turret, pressing mechanism and cooling water system; Frame comprises soldering turret support and clamping limb composition, the utility model fixedly projection welder and hanging spot-welder is optimized, the power-on and power-off polar cap that can only weld the mash welder of sheet metal component is originally improved, change the rod shaped structure of projection welder upper/lower electrode into, the welding machine cylinder of projection welding top electrode and air pressurized mechanism is connected as a single entity, and is provided with cooling water system in projection welding top electrode and the projection welding bottom electrode; The soldering turret support adopts the hanging type structure, and projection welder is suspended in the air, and weldment is directly put into the projection welding top electrode and the projection welding bottom electrode bar of projection welder during welding from the bottom, and operating flexibility is better.
Regulating the digital control system of control welding current, weldingvoltage and time is made up of microcomputerized control case and external data programmable device, the microcomputerized control case has the function of storage, output data, required welding control parameter is imported by the external data programmable device, the microcomputerized control case links to each other with the external data programmable device by the access port of side.
Projection welder links to each other with transformer by the water, electricity and gas pipeline, and the cable that connects projection welder and transformer is a Water cooling cable, and Water cooling cable is not only switched on but also water flowing; Transformer is a water cooled transformer, and the voltage of 380V becomes the 24V safe voltage by behind the transformer, arrives two arms of soldering turret then through cable, forms a welding circuit during duty; Short circuit current by two tong arms during welding produces high temperature, reach the purpose of melting workpiece, also can produce heat in soldering turret part and cable simultaneously, be to guarantee the operate as normal of welding machine, its purpose of used Water cooling cable and water cooled transformer all is at the high temperature of soldering turret part and cable generation when being cooled with circulating water welding.Gases at high pressure in the pipeline enter in the oil water separator that is attached to the pneumatic triple piece on the transformer by flexible pipe, filter the impurity of gases at high pressure, gas after the pressure regulator valve of regulating pneumatic triple piece according to the pressure of desired gas will be regulated send into pneumatic triple piece oil sprayer in, under the action of magnetic valve, the gases at high pressure of band oil not only promote the action of welding machine cylinder, also lubricated simultaneously the welding machine cylinder, welding machine cylinder action drives projection welding top electrode and the work of projection welding bottom electrode bar, and the nut (bolt) of stamping parts diverse location is welded.
Adopt this underslung projection welder, but the nut (bolt) of the big stamping parts diverse location of weld size overcomes fixedly projection welder throat opening smaller defect, has also avoided CO
2Welding is to the pollution of environment, and cheap, only for 10% of fixing projection welder cost of investment, because of employing hanging type structure, saved the space; Easy to operate, be easy to promote.
