Embodiment Construction

[0018] Such as figure 1 , 2 As shown, the mutual positioning welding method for the grid box structure of the hydraulic support, the process steps are as follows: ①. According to the production design drawings of the grid box structure of the hydraulic support, several sets of plates are cut and formed, and according to the production design Drawing spot welding forming;

[0019] ②. Take the two sets of step ① and install the grid-type box structures 2 and 5 formed by welding, and place them on the two displacers 1 and 10 with the same setting state at the same station. The two displacers 1, 10 Between 10, a positioning welding device is provided, and the positioning welding device includes a synchronous displacement device 7 whose moving track is perpendicular to the straight line where the two displacers 1, 10 are located. The synchronous displacement device 7 is provided with the two displacers 1, 10 10 is a horizontal beam 3 that is parallel to the straight line and can ...

Abstract

The invention relates to the hydraulic support structural member welding processing field, in particular to a mutual tack welding method for hydraulic support grid box type structure. The invention solves the problems that the existing hydraulic support grid box type structure is processed by manual welding, welding fabrication quality can not be ensured, and the cost of welding by automatic robot is too high; and the method includes the following steps: (1) sorting and mounting welding fabrication grid box type structure; (2) respectively placing two grid box structures on two positioners between which a tack welding position is arranged; (3) realizing positioning of a tack welding device and the two grid box type structures; (4) adjusting arc starting position of a welding gun and arc starting; (5) starting a synchronous shifting device and welding the welding position by the welding gun; (6) controlling the two positioners to turn on the corner and carrying out corner transition welding by the welding gun; (7) welding the welding position in another direction after the welding of the welding position is completed. The technology is reasonable and concise, feasibility is high, welding quality can be ensured, production efficiency is high, and implementation cost is relatively low.

Description

technical field [0001] The invention relates to the field of welding processing of hydraulic support structural parts, in particular to a mutual positioning welding method for grid-type box structures of hydraulic supports. Background technique [0002] At present, the grid type box structure of the hydraulic support is usually processed by manual welding method and automatic robot welding method. Manual welding: holding the welding torch by hand, manipulating the electric welding machine, and performing welding on the welding parts of the box structure, but due to different manual operation skills, it is easy to cause unstable welding quality and overall different welding strength; automatic robot welding: through welding Special software programming, the computer automatically controls the welding trajectory of the box-type structure to perform forming welding. Although it can overcome the shortcomings of different welding quality caused by different manual operation skill...
