Description
Technical Field
The invention belongs to the technical field of automatic welding equipment, and particularly relates to an adjustable and replaceable welding jig.
Background
In the welding process of the double-head welding jig, spot welding is triggered by adopting displacement, when the soldering tin areas of workpieces to be welded are different in height or errors exist in the product tooling process, so that errors are accumulated, and further the soldering tin areas are different in height, the problems of insufficient soldering, infirm welding and the like easily exist when the double-head welding device carries out soldering tin operation on the soldering tin areas different in height,
in order to enhance the welding effect of the double-head welding jig on the welding positions with height difference, after research and design, I propose a double-welding-head structure, one of the double-welding heads adopts a spring pressure nut adjustment mode to enable the double-welding head to carry out displacement adjustment in the whole movement stroke, further enable the double-welding head to carry out spot welding with the soldering tin areas with different heights, in particular, in the whole movement stroke, one of the two welding heads which are parallel and level in the initial state is firstly contacted with a surface to be welded, further in the continuous movement process, the spring is compressed, further the heights of the two welding heads are staggered, further both the two welding heads are contacted with the surface to be welded, further the spot welding of the soldering tin areas with different heights is completed, and the adaptability of the double-head welding jig to the height difference of the soldering tin areas is enhanced,
but I find in the subsequent long-time use process that on one hand, because the welding pressure of the two welding heads and the soldering tin area is different, the spot welding effect of the two welding heads is different, if the pressure to the soldering tin area is too small, poor contact or even no contact with the soldering tin area is easy to occur, so that a welding core cannot be formed at the welded part, and further the welding quality cannot be effectively controlled, on the other hand, in the welding process, an elastic element on a single welding head is easy to generate permanent elastic deformation in the long-time compression process, so that the heights of the two welding heads are deviated, although the pressure of the elastic element can be manually adjusted in the later period, so that the error is reduced, in the long-time use process, the hidden danger of the welding quality still exists,
