Automatic polishing system for water turbine blades

Abstract

The invention discloses an automatic polishing system for water turbine blades. The automatic polishing system for the water turbine blades comprises a clamping platform, an industrial robot, a polishing control system and a visual image system, and wherein the clamping platform is used for positioning and clamping the water turbine blade to be polished; the industrial robot is provided with a polishing mechanism, and the industrial robot is controlled by a polishing control system and is used for polishing the blade clamped on the clamping platform; and the polishing control system directs atthe current polishing surface of the blade to be polished and is used for planning a corresponding polishing path, then the planned polishing path is converted into a polishing action control programof the industrial robot and is conveyed to the industrial robot, and the visual image system is used for detecting the polishing quality and feeding back the polishing quality to the polishing control system. According to the automatic polishing system for the water turbine blades, the surface of the impact-type water turbine blade formed by precision casting can be provided with an automatic, intelligent and unified polishing treatment; and thus the polishing quality of the surface of the blade can be improved accurately and reliably.

Description

technical field [0001] The invention relates to an automatic grinding technology, in particular to an automatic grinding system for water turbine blades. Background technique [0002] The blades of the reaction turbine are the core components in the runner, which are used to convert the kinetic energy of water into rotational mechanical energy. Since the blades of the impact turbine need to serve in the repeated impact environment of high-pressure water for a long time, it is required to have good mechanical properties, cavitation resistance, corrosion resistance and wear resistance. Based on this, the blades of the impact turbine are usually It is formed by precision casting. [0003] The impact turbine blades made of precision casting have surface defects such as oxide layer and excess machining allowance before flaw detection and finishing. These surface defects must be polished and removed before flaw detection. [0004] At present, the grinding operation of the impact...

AI Technical Summary

Problems solved by technology

[0004] At present, the grinding operation of the impact turbine blade surface is mainly realized by manual grinding, which not only has low grinding efficiency, high labor intensity, long grinding cycle, and poor economy; moreover, as we all know, the grinding quality of manual grinding depends entirely on Due to the personal technical level of the operators, it is difficult for the same operator to achieve consistent grinding quality of different grinding parts and the grinding quality of different operators, which makes it impossible to achieve uniform grinding quality on the blade surface manually, resulting in The grinding quality is unstable and unreliable, which is not conducive to the subsequent finishing process
