Embodiment 1
[0017] Such as Figure 1 to Figure 2 The multi-workpiece assembly welding positioning device shown includes a bottom plate 11 welded with a vertical plate I12 and a vertical plate II9. The vertical plate I12 and the vertical plate II9 are respectively provided with positioning holes, and the two positioning holes are arranged coaxially; there is a positioning The pin shaft 1 is installed on the positioning holes of the vertical plate I12 and the vertical plate II9 through the bushing I2 and the bushing II8 in sequence. The positioning sleeve part on the pin head side is connected. The length of the sliding sleeve part of the bush I2 is less than the thickness of the vertical plate I12; the bushing II8 is composed of a sliding sleeve part slidingly connected with the positioning hole of the vertical plate II9 and located on the side of the positioning spacer sleeve 5. The push sleeve part is connected, the length of the sliding sleeve part of the bushing II8 is greater than the...

The invention discloses an assembly welding positioning device and assembly welding method for multiple workpieces. The assembly welding positioning device comprises a bottom plate provided with a first vertical plate and a second vertical plate. The first vertical plate and a second vertical plate are each provided with a positioning hole, and the two positioning holes are coaxially formed. A positioning pin shaft sequentially passes a first lining and a second lining and is installed in the positioning hole of the first vertical plate and the positioning hole of the second vertical plate in a penetrating mode. A positioning separation sleeve is installed in the position, between the first lining and the second lining, of the positioning pin shaft in a penetrating mode. A bolt with a pressing plate is installed at the tail end, on the side where the second lining is located, of the positioning pin shaft through a center threaded hole. The second lining is formed by connecting a sliding sleeve part in sliding connection with the positioning hole of the second vertical plate with a pushing sleeve part located on the side where the positioning separation sleeve is located. A positioning separation plate with an inverted U-shaped opening is installed in the position, between the positioning separation sleeve and the first vertical plate, of the positioning pin shaft in an inserting mode. A lifting hole is formed in a plate body, located above the inverted U-shaped opening, of the positioning separation plate. According to the assembly welding positioning device and assembly welding method for the multiple workpieces, compared with the prior art, the problem that welding positioning elements and welding pieces are difficult to separate after the existing multiple workpieces are subjected to assembly welding can be solved.
Description
technical field [0001] The invention relates to the technical field of welding tool manufacturing, in particular to a positioning device for multi-workpiece assembly welding. Background technique [0002] In design, for some weldments composed of at least two parts with holes, the coaxiality requirements of the holes and the spacing tolerance requirements of the parts will be set. In the welding process of multiple workpieces, it is necessary to ensure the post-weld size between the workpieces and the coaxiality of the workpiece holes after welding. Welding positioning components are often used to ensure that, because multiple workpieces are welded after welding The phenomenon of deformation makes it difficult to separate the welding positioning element from the weldment. Usually, it is separated by forced means such as hammering, which not only affects the dimensional accuracy and position accuracy of the weldment, but also reduces production efficiency.
