The welding method of the welding mechanism of above-mentioned project-welding nut has following two kinds:
First kind of welding method is only to carry out the projection welding operation, specifically comprises the steps:
A: utilize alignment pin to fix nut to be welded, start hold-down mechanism, utilize compact heap and alignment pin that nut to be welded is compressed;
B: first cable is connected with first electrode of a mash welder, second cable is connected with second electrode of said mash welder; Utilize first electrode, second electrode of said mash welder to send electricity, accomplish projection welding nut to be welded to compact heap and alignment pin.
Second kind of welding method is to carry out projection welding and spot welding operation simultaneously, specifically comprises the steps:
A: utilize alignment pin to fix nut to be welded, start hold-down mechanism, utilize compact heap and alignment pin that nut to be welded is compressed;
B: first cable is connected with a workpiece of treating spot welding, second cable and another is treated the workpiece of spot welding is connected; Utilize first electrode, second electrode of a mash welder to send electricity, when the workpiece of treating spot welding carries out spot welding, realize sending electricity, accomplish projection welding nut to be welded to compact heap and alignment pin to two workpiece of treating spot welding.
Further; Said hold-down mechanism is made up of support column, lever, cylinder; The equal vertical fixing of said support column and cylinder is on supporting seat; Said lever is movably installed in the support column top through articulated manner, and an end of lever is connected with the end of the piston rod of cylinder through articulated manner, and the bottom surface of the other end of lever is equipped with compact heap.Utilize the thrust of cylinder piston rod, can constantly compact heap be pressed on and treat on the project-welding nut, thereby guarantee welding quality.
Further, also be provided with second support column that is used to support the spot welding parts on the said supporting seat, conveniently carry out spot welding and projection welding operation simultaneously.
Further, for guaranteeing the projection welding quality, said compact heap and alignment pin are copper.
Further, for improving versatility, said supporting seat and alignment pin utilize the mode of threaded engagement to install and fix, and when the nut of welding different size, can change different alignment pins, to guarantee that installation is firm between nut and the alignment pin, improve welding quality.
Further, for easy to connect, an end of said first cable is fixedly connected with compact heap, and the other end is connected with metal clip; One end of said second cable is fixedly connected with alignment pin, and the other end is connected with metal clip.When only carrying out the projection welding operation, can utilize metal clip directly to link to each other with the electrode of mash welder; When carrying out spot welding and projection welding operation simultaneously, can utilize metal clip to link to each other with the workpiece of treating spot welding.
The welding mechanism of project-welding nut of the present invention is simple in structure; Low cost of manufacture; The projection welding operation be can only carry out or spot welding and projection welding operation carried out simultaneously; Avoided to utilize projection welder that nut is carried out the projection welding operation earlier before the traditional spot welding operation, reduced middle operation and personnel's waste, used efficient and convenient, highly versatile, efficient height.
