Tool for guiding welding machine heads to move in arc direction through double rails

Abstract

The invention discloses a tool for guiding welding machine heads to move in the arc direction through double rails. The tool comprises double-rail assemblies, rubber guide wheel sets, arc vertical direction stroke wheel sets, arc vertical direction stroke islands, the welding machine heads, structural middle plates and the like, wherein motor sets control the rubber guide wheel sets and the arc vertical direction stroke wheel sets; and each double-rail assembly comprises an inner arc rail and an outer arc rail, the arc vertical direction stroke islands are connected between the inner arc rails and the outer arc rails in a bridging mode through the structural middle plates, each arc vertical direction stroke island comprises a middle stroke plate and a middle stroke column, the middle stroke plates are guided by the arc vertical direction stroke wheel sets at moving paths on the middle stroke columns, the structural middle plates are guided at moving paths on the double-rail assemblies through the rubber guide wheel sets, and the welding machine heads are fixed to the middle stroke plates. The tool effectively reduces the operation difficulty of a welder, accelerates the welding speed, improves the manufacturing efficiency, reduces the surfacing layer connection, effectively reduces the welding heat input and the post-welding deformation, and improves the surfacing layer quality.

Description

technical field [0001] The invention belongs to the technical field of mechanical manufacturing, and belongs to the technical field of manufacturing surfacing welding lining plates in fan coal mill equipment, and in particular relates to a tool that uses double tracks to guide the arc movement of the head of a welding machine. Background technique [0002] When the high-speed fan coal mill is running, the striking wheel part itself rotates at a high speed, thereby driving coal, cinder and coal powder to be projected around the center of the striking wheel shaft. One of the main functions of the grid surfacing liner in the casing part It is through the grid surfacing layer to block the projectiles driven by the striking wheel, such as coal blocks thrown around. At present, the grid surfacing lining plate of the fan coal mill equipment casing parts in the energy field is generally manufactured by using manual arc welding, semi-automatic gas shielded welding or both methods.

AI Technical Summary

Problems solved by technology

Manufacture of grid surfacing welding lining plate by manual arc welding, semi-automatic gas shielded welding or both methods will also cause problems such as long construction period, large heat input per unit length and large deformation after welding.
