Abstract

The invention relates to a mechanism, in particular to an electric spark deposition mechanism for a functional coating on the inner wall of a slender pipeline. The purpose is to solve the problems that manual electric spark deposition for the functional coating on the inner wall of the slender pipeline is difficult to carry out, the deposition quality is poor, and the efficiency is low. The electric spark deposition mechanism is based on modular design, and includes a supporting shaft, a cam rotating device, a primary supporting plate, an electrode rotating vibration device, a protective gas pipeline and a secondary supporting plate. Combined with a numerical control technology and an electric spark deposition surface strengthening technology, an electro spark deposition process platform for the functional coating of the inner wall of the slender pipeline is built, so that the numerical control and automatic deposition for the functional coating on the inner wall of the slender pipeline is realized. The electric spark deposition mechanism for the functional coating on the inner wall of the slender pipe is obtained.

Description

technical field [0001] The invention relates to a miniature deposition mechanism, in particular to an electric spark deposition mechanism for functional coating on the inner wall of a slender pipeline. Background technique [0002] Due to its excellent quality (such as: the coating is metallurgically bonded to the substrate; the residual stress of the deposited layer is small, the deformation is small; the deposition process is simple, the coating structure is fine, etc.), in aviation, aerospace, military industry, automobiles, tools, etc. , Die and other fields are increasingly widely used. However, the EDM deposition of the functional coating on the inner wall of the slender pipe is still performed manually, which is extremely inconvenient, the deposition efficiency and automation are low, and the deposition quality is unstable. The existence of the above problems seriously limits the application of this technology in the field of electrospark deposition of functional coa...
