Control method of automatic welding production system of net rack connecting rods

Abstract

The invention discloses a control method of an automatic welding production system of net rack connecting rods. The control method includes the steps of steel pipe line delivering, automatic welding,finished product line releasing and the like. Accurate coordinate grabbing and stacking of steel pipe workpieces can be achieved through a steel pipe line delivering unit and a steel pipe line releasing unit, accurate axial positioning of the steel pipe workpieces can be achieved through steel pipe radial clamping and positioning devices, bolts can be subjected to accurate coordinate grabbing andput in the ends of the steel pipe workpieces before welding through an automatic bolt implanting unit, accurate coordinate grabbing and coordinate positioning and connecting of sealing plate or cone head workpieces can be achieved through a sealing plate or cone head supply unit, the sealing plate or cone head workpieces can be accurately and coaxially coordinate-positioned at the welding ends ofthe steel pipe workpieces through sealing plate or cone head pushing devices, through cooperative work of steel pipe rotation drive devices and welding gun devices, one-time welding forming of complete annular weld joints can be achieved, and the control method is especially suitable for welding procedures of the net rack connecting rods.

Description

technical field [0001] The invention relates to a control method for an automatic welding production system, in particular to a control method for a production system suitable for automatic welding of grid connecting rod workpieces, and belongs to the technical field of grid connecting rod manufacturing. Background technique [0002] The grid structure is a space structure with a large span covered by connecting multiple grid connecting rods through nodes in a certain grid form. The grid structure has the advantages of good integrity, large space rigidity, and stable structure. Not only is it light in weight , The on-site construction workload is small, the construction speed is fast, and the height of the grid structure is small, which can effectively use the space, so it is widely used in the construction industry. [0003] The grid structure nodes made of steel mainly include cross-plate nodes, welded hollow ball nodes and bolt ball nodes. The grid structure composed of ...

Problems solved by technology

[0005] 1. Although the pre-spot welding can be carried out by means of tooling positioning, there will still be spot welding deviations in the manual operation method, which cannot accurately ensure the coaxiality of the sealing plate or the through hole of the cone head and the steel pipe body, which will affect the product quality , It is easy to cause subsequent installation problems such as installation eccentricity and eccentric load on the grid connecting rod;

[0006] 2. Although the welding is carried out on the basis of pre-spot welding, the we...
