Problems solved by technology

[0006] 1. All existing laser cladding processes cannot achieve precise surface forming, and cannot directly meet the relevant technical requirements in terms of dimensional accuracy and surface quality. The removal of redundant cladding layers on general-purpose CNC machine tools involves two Inconsistent secondary clamping standards, uneven allowance, thin-walled deformation characteristics of the blade, secondary programming and many other technical problems lead to easy cutting of the repair layer, low machining efficiency for removing the allowance, and low yield of processing repairs;
[0007] 2. Manually grinding the blades of the laser fusion repair layer has high technical requirements for workers, and the labor load is large, so it is difficult to maintain a stable removal of material surplus processing. In addition, manual grinding dust pollution is serious, and the working environment is extremely harsh and harmful
[0008] 3. It is difficult for industrial robots to achieve high-precision blade fusion surfacing due to the limitation of their own repeat positioning accuracy, which not only leads to excessive subsequent grinding allowances, but also limits the low stiffness of the robot to the removal of the fusion repair layer. The efficiency is so low that it directly affects the production efficiency of blade repair and remanufacturing

Abstract

The invention discloses a laser cladding and self-adaptive milling integrated combined numerical-control machine tool for repairing a blade. By the adoption of the laser cladding and self-adaptive milling integrated combined numerical-control machine tool for repairing the blade, the problems that margin cutting residues are large and a repair layer is likely to be cut due to reapeated clamping and the machining precision is not stable and the efficiency is low due to manual copping are mainly solved. The laser cladding and self-adaptive milling integrated combined numerical-control machine tool for repairing the blade mainly comprises a double-T-shaped tool body, a first stand column mechanism, a second stand column mechanism, a numerical-control rotary workbench, a tip, a milling spindle and a laser powder cladding device. The milling spindle which can swing is arranged on a sliding plate of the first stand column mechanism. A milling tool or a coordinate measuring head can be installed on the milling spindle. A gas protective nozzle is arranged on a sliding plate of the second stand column mechanism. The blade is clamped between the numerical-control rotary workbench and the tip so as to be repaired. The laser cladding and self-adaptive milling integrated combined numerical-control machine tool for repairing the blade is ingenious in structural design, flexible in technological combination, high in universality and high in repairing and removing precision, the rate of finished products is high, the production cost is greatly reduced, and the laser cladding and self-adaptive milling integrated combined numerical-control machine tool has high practical value and promotional value.

Description

technical field [0001] The invention belongs to the field of mechanical manufacturing, and relates to automation equipment for the remanufacturing process of blade parts. Specifically, it relates to a method of using laser fusion to repair the damaged blade surface and simultaneously combining with numerical control milling to realize cladding and surfacing welding. An integrated compound processing machine tool for high-precision and high-efficiency removal of excess material on parts. Background technique [0002] As an important core part of power plants such as aero-engines and steam turbines, blades operate in harsh working environments such as high temperature, high pressure, vibration, and huge centrifugal force for a long time. The blade surface will inevitably produce corrosion, fatigue cracks, and even fractures. cause a major accident. In addition, the blade is a key part of the turbine that is easy to wear, high in cost and large in quantity. Generally speaking,...
