Automatic welding method of flow production line for hydraulic support grid box type structure members

Abstract

The invention relates to the field of welding fabrication of hydraulic support structure members, particularly to an automatic welding method of a flow production line for hydraulic support grid box type structure members, which solves the problem that the traditional manual welding method cannot guarantee the welding forming quality and workpieces cannot be completely and automatically welded due to deformation caused by a unit type automatic robot due to thick plate welding thermal cycle. The automatic welding method comprises the following concrete steps of: cutting and forming the grid box type structure members; automatically counting and assembling bottom plates and main rib plates; preheating the counted and assembled bottom plates and main rib plates; automatically welding the main rib plates; automatically counting and assembling separation plates; preheating the counted and assembled separation plates; automatically welding the flat joints of the separation plates; automatically welding the left vertical joints of the separation plates; automatically welding the right vertical joints of the separation plates; counting and assembling function parts; counting and assembling cover plates; automatically welding the flat joints of the cover plates; automatically welding the arc joints of the cover plates; and circulating the above steps. The method provided by the invention is reasonable and simple in process, strong in operability and high production efficiency, and can guarantee the welding quality.

Description

technical field [0001] The invention relates to the field of welding processing of structural parts, in particular to an automatic welding process of an assembly line for grid-type box-type structural parts of mining hydraulic supports. Background technique [0002] At present, the grid-type box structure of hydraulic support is usually processed by manual welding process and unit robot automatic welding process. [0003] Manual welding: manually hold the welding torch, manipulate the electric welding machine, and perform forming welding on the welding parts of the box structure. However, due to different manual operation skills, it is easy to cause unstable welding forming quality and overall different welding strength; [0004] Unit robot automatic welding: adopts the independent station operation mode of one-time positioning and clamping and overall welding, through the special welding software programming, the computer automatically controls the welding track to implemen...
