Automatic hydraulic cylinder barrel inner wall repairing method

Abstract

The invention relates to the field of hydraulic cylinder repairing, in particular to an automatic hydraulic cylinder barrel inner wall repairing method. The method comprises the steps that (1) a hydraulic cylinder barrel inner wall is cleaned, and oil contamination impurities are removed; (2) defect positions, defect sizes and defect types of the hydraulic cylinder barrel inner wall are determined; (3) a numerical control system processes the information to generate milling forms and welding forms of all defect areas and fine boring parameters of the cylinder barrel inner wall; (4) the numerical control system controls a spindle and a cutter to conduct milling machining on all the defect areas according to defect coordinates and the defect milling forms; (5) the numerical control system controls the spindle and a welding gun to carry out automatic precise surfacing on all the milling areas; and (6) the numerical control system controls the spindle and a floating boring cutter in the cutter to conduct precise boring on the cylinder barrel inner wall, and the cylinder barrel inner wall is machined to be in an uniform size. According to the method, the automation is completely adopted, a point-to-point repairing mode is adopted for a hydraulic cylinder, large-area cutting and surfacing are avoided, the damage to an original cylinder body is reduced, and the material waste is reduced.

Description

technical field [0001] The invention relates to the field of hydraulic cylinder repair, in particular to an automatic repair method for the inner wall of a hydraulic cylinder barrel. Background technique [0002] With the progress of the times, green development has become an important trend. At present, hydraulic cylinders are widely used in mining, energy, machinery manufacturing, aerospace and other industrial fields. A large number of failed parts, if the failed parts are directly scrapped, it will be a great waste of resources and energy, and the failure is usually caused by local damage to the inner wall of the cylinder, the damaged area is small, and the depth is shallow, which can be reused through repair. The hydraulic prop cylinder is one of the typical representatives. At present, there are many methods for repairing the inner wall of the hydraulic cylinder, and the more mainstream methods include surfacing, electroplating, and necking. The principle of the surf...
