Embodiment Construction

[0017] Below in conjunction with accompanying drawing and embodiment the present invention will be further described:

[0018] Such as figure 1 , figure 2 As shown, the present invention consists of an electrode rod 1, a first electrode arm 2, a second electrode arm 3, a round electrode 4, a cylindrical electrode 5, a copper spacer 6, a first positioning block 7, a second positioning block 8 and a leaf spring 9 and other components. Wherein, the middle parts of the two side-by-side electrode rods 1 are hinged together, and the setting method of the electrode rods 1 is the same as that of the prior art, which will not be repeated here. A first electrode arm 2 is installed on the lower end of one of the electrode rods 1, and a round electrode 4 is fixedly installed on the inner side of the lower end of the first electrode arm 2; a second electrode arm 3 is installed on the lower end of the other electrode rod 1, and the second electrode Two cylindrical electrodes 5 are insta...

Abstract

The invention discloses a pair of double-head separate resistance spot welding tongs. A first electrode arm (2) is mounted at the lower end of an electrode rod (1); a second electrode arm (3) is mounted at the lower end of another electrode rod (1); a round-head electrode (4) is fixed on the inner side of the lower end of the first electrode arm (2); two cylinder electrodes (5) are fixed side by side on the inner side of the lower end of the second electrode arm (3); distances from the round-head electrode (4) to the two cylinder electrodes (5) are equal; and a copper cushion block (6) is arranged among the round-head electrode (4) and the two cylinder electrode (5). The pair of welding tongs can be used for welding similar workpieces such as filler caps, is free from interference with the workpieces, can effectively prevent damaging the workpieces in the welding and clinching process, is simple to operate, and can weld two points simultaneously, the welding quality is guaranteed, the turning time of the pair of welding tongs is reduced, and the welding efficiency is improved greatly.

Description

technical field [0001] The invention belongs to the field of welding technology, and in particular relates to a double-head separated type resistance spot welding welding tongs. Background technique [0002] Under the current automobile production technology conditions, welding technology is indispensable in the manufacturing process of automobile body-in-white, among which mature spot welding welding process and superior welding tongs performance play a key role in the quality of the body. [0003] Spot welding is a welding process that clamps the welding workpiece together by electrode pressure, and releases a large current through both ends of the electrode to melt the contact surface between the workpiece and the electrode to form a weld nugget to achieve the purpose of welding. It is very necessary to select different types of welding tongs for different welding positions, which not only improves the quality of solder joints, but also optimizes the production cycle. Ho...
