Part repairing device based on additive and decreasing manufacturing and application method of part repairing device

Abstract

The invention provides a part repairing device based on additive and decreasing manufacturing. The part repairing device comprises a lathe bed (1) and a worktable (2), and is characterized in that a parallel clamping device (3) is arranged at the upper part of the lathe bed (1); a three-dimensional scanner (6), an additive manufacturing module fixing mechanism (701) and a decreasing machining module fixing mechanism (702) are arranged at the side part of the lathe bed (1); an additive manufacturing module (4) is arranged on the additive manufacturing module fixing mechanism (701); a decreasing machining module (5) is arranged on the decreasing machining module fixing mechanism (702); and the worktable (2) is located under the parallel clamping device (3). With the adoption of the part repairing device, after model three-dimensional data is obtained, a regular surface is obtained by using a decreasing machining manner, and then an additive manufacturing repairing process is carried out; finally, surface machining also can be carried out to obtain a part with relatively good surface quality; and in a whole process, the part only needs to be clamped and positioned once, manual errors are reduced, and a repairing effect is relatively reliable.

Description

technical field [0001] The invention belongs to the field of machine tool design. It relates to a laser cladding repair device, in particular to a part repair device based on additive and subtractive material manufacturing. Background technique [0002] After decades of development, additive manufacturing technology has shown great advantages over traditional processing methods in the manufacture of complex structural parts. Due to its short manufacturing cycle, high automation, and low material consumption, this technology has been more and more widely used. [0003] Due to the continuous development of industrial production, the requirements for mechanical equipment have been continuously improved, and more and more complex structural parts have appeared in mechanical equipment. Some key parts may have to be replaced because local failure damage will have a huge impact on the entire equipment. In some special occasions, due to partial damage of key parts, replacement pa...

AI Technical Summary

Problems solved by technology

The traditional surfacing repair technology has a low degree of automation and a high degree of dependence on manual operations, which greatly reduces the reliability of repair quality

The existing repair equipment based on laser cladding has the problem of separation of machining processes such as additive repair and milling profiling. Interference with parts, resulting in very limited processing capabilities of existing repair equipment
