Summary of the invention
The purpose of this invention is to provide a kind of electric spot-welding machine, this welding machine can be finished the welding of two solder joints simultaneously in same operation, and the distance of two solder joints is adjustable, the welding high conformity of solder joint, and welding is quick, and operating efficiency improves greatly.
In order to achieve the above object, electric spot-welding machine of the present invention is made of the main frame, head and soldering tip three parts that play the power supply regulating and controlling effect, it is characterized in that having on the head welding head holder that can distinguish clamping two parallel pole formulas soldering tip or four point electrodes, and be connected with the pulse transformer of main frame by two groups of identical output cables of (four) electric property, to guarantee the uniformity of two outputs.
Welding head holder of the present invention is made of performances such as (comprise identical) electricity of two equalizations parallel welding head holder, each parallel welding head holder is made of preceding fixture block and back fixture block, before and after be connected by two identical shell fragments of elasticity up and down between fixture block, and fixture block insulation in front and back is separated by insulation spacer; Two alignment pins, spacing adjusting screw(rod) and compression spring have been installed between two parallel welding head holders, and adjustable range is about 1-25mm; In two groups of output cables, a cable is connected on the back fixture block of welding head holder, fixture block before another root cable connects; Two parallel welding head holders are connected with the head of handling the soldering tip stroke with soldering tip pressure is provided with same interface.Before and after being installed in for the ease of soldering tip on the welding head holder of fixture block, and the spacing that satisfies two parallel welding head holders regulates in more among a small circle, and the part that soldering tip is connected with welding head holder can be made rectangular cylinder, square cylinder or semicylinder.
Because electric spot-welding machine of the present invention has two welding head holders, directly is connected with pulse transformer by two groups of identical output cables of (four) electric property, makes the welding that can finish two solder joints in same operation simultaneously.Between the fixture block of front and back, dispose up and down two shell fragments that elasticity is identical,, also can make to be added in two welding pressures on the welding head holder and to be consistent, guarantee the uniformity of two solder joint welding qualities even two pads of welded piece have the fine difference of height.Two alignment pins, spacing adjusting screw(rod) and compression spring have been installed between two parallel welding head holders, have been made two welding head holder spacings adjustable flexibly, adjustable range is about 1-25mm, and it is uneven to occur two soldering tip height after regulating.
