Problems solved by technology

[0003] At present, most of the engine crankshaft laser cladding repair is to repair the journal, but it is difficult to repair the crankshaft fillet
This is because for a laser with a three-axis motion structure, the crankshaft fillet is limited by the structure, the laser head is parallel to the repair plane, the powder and the laser beam cannot touch the fillet, and the fillet is difficult to process

Abstract

The invention discloses an engine crankshaft circular bead laser cladding repairing device and method solving the problem that in the prior art, crankshaft circular bead repairing is limited and having the beneficial effects of being convenient to operate and low in cost. According to the scheme of the engine crankshaft circular bead laser cladding repairing device and method, the engine crankshaft circular bead laser cladding repairing device comprises a crankshaft cladding clamp used for clamping a crankshaft and a three-axis driving mechanism arranged on one side of the clamp support; the crankshaft cladding clamp comprises a chuck used for driving the crankshaft to rotate around the axis of the crankshaft, the chuck is supported through a clamp support, and the crankshaft cladding clamp can ascend and descend so as to drive the crankshaft to incline in the set angle range; the three-axis driving mechanism comprises a supporting frame, the supporting frame supports a first sliding rail, the first sliding rail is provided with an X-direction guide rail capable of moving along the first sliding rail, the X-direction guide rail is provided with a Y-direction connecting rod capable of moving along the X-direction guide rail, the Y-direction connecting rod is provided with a Z-direction lead screw capable of moving up and down relative to the Y-direction connecting rod, and the Z-direction lead screw is fixed to a laser cladding head.

Description

technical field [0001] The invention relates to the field of laser cladding, in particular to a laser cladding repair device and method for engine crankshaft rounded corners. Background technique [0002] Crankshafts operate in a high-pressure, high-temperature working environment for a long time, and are often scrapped due to friction, scratches and cracks on the journal surface, resulting in huge waste of resources and economic losses, and most of the scrapped engine crankshafts contain high remanufacturing value. If it is repaired by laser cladding technology, the waste caused by scrapping the crankshaft can be reduced, and the performance of the crankshaft surface can also be improved. Laser cladding technology refers to placing selected coating materials on the surface of the coated substrate with different filler methods, melting it and the thin layer of the substrate surface at the same time through laser irradiation, and forming a very low dilution after rapid solid...
