The invention discloses a vertical machine tool for bead welding repair of a crankshaft. The vertical machine tool comprises a table frame and a clamping device, wherein the clamping device comprises a bottom disk, a pin, a rotary disk, a clamping disk, a bead welding device and two welding guns; the bottom disk is arranged on the table frame, and a center hole and one or more pin holes are formed in the bottom disk; the pin is arranged on the center hole or the pin holes; the rotary disk is erected on the table frame through a first lifting device, positioned above the bottom disk and driven by a rotating motor to rotate; the clamping disk is arranged on the rotary disk; the bead welding device comprises a bead welding seat and is erected on the table frame through a second lifting device; the two welding guns are arranged on the bead welding seat, one of the welding guns is used for transporting welding wires, and the other welding gun is used for transporting oxyacetylene gas. The vertical machine tool disclosed by the invention can perform the bead welding repair on a main shaft neck and a connecting rod shaft neck of the crankshaft, and is high in automation degree and repair efficiency.
Description
technical field [0001] The invention relates to the field of crankshaft remanufacturing, in particular to a vertical crankshaft surfacing repair machine tool. Background technique [0002] At present, it is widely used in diesel engines or other reciprocating machinery (such as air compressors, reciprocating steam engines, etc.), the crankshaft is a precise and expensive important part that can withstand alternating loads and high mechanical strength. Damage to the parts will seriously affect the work of the whole machine. The damage of the main journal of the crankshaft and the crank journal of the connecting rod is a common part damage. At present, the commonly used remanufacturing repair methods for the damage of the main journal of the crankshaft and the connecting rod journal include brush plating, spraying and surfacing welding, etc. The existing surfacing The automation of welding equipment is low, and the labor intensity of workers is high. At present, the surfacing...
