Problems solved by technology

[0004] At the same time, due to the fluctuation of the surface of the welding workpiece, in order to ensure the stability of the welding process, the width and height of the weld are not absolutely uniform. In this case, the weld reinforcement obtained by milling pre-processing will also have fluctuations. On this basis On the other hand, grinding the weld parts with large undulations may cause insufficient grinding or scratch the base metal

Embodiment

[0042]In this case, a weld method based on adaptive control is mixed, the method comprising a weld milling groughing and a weld grinding process.

[0043]During the weld milling coarse process, adaptive control of weld processing is achieved by the real-time feedback adjustment of the milling position detecting unit and the control center to ensure that the balance after milling of roughing is high for milling target welding. Milling target weld is high means that the weld is the target distance of the surface of the workpiece base material after the milling roughing is completed.

[0044]During the weld grinding process, adaptive control of weld processing is achieved by the real-time feedback adjustment of the grinding position detecting unit and the control center, ensuring that the welding of the grinding finishing is high as the grinding target weld. Yu high. The balance of the grinding target weld is the target distance of the weld as the surface of the workpiece base material after...

Abstract

The invention provides a weld seam mixed grinding method and system based on self-adaptive control. The method comprises one-time welding seam milling rough machining and one-time welding seam grinding finish machining. In the weld seam milling rough machining process, self-adaptive control over weld seam machining is achieved through real-time feedback adjustment of a milling position detection unit and a control center, and it is guaranteed that the weld seam excess weld metal obtained after milling rough machining is the milling target weld seam excess weld metal; and in the weld seam grinding finish machining process, self-adaptive control over weld seam machining is achieved through real-time feedback adjustment of a grinding position detection unit and the control center, and it is guaranteed that the weld seam excess weld metal obtained after grinding finish machining is the grinding target weld seam excess weld metal. The system comprises a milling subsystem, a grinding subsystem and the control center. When the method and the system are used for weld seam grinding, the conditions of insufficient grinding and base metal scratching in the machining process can be effectively avoided, the service life of a grinding tool is prolonged, and a high-quality grinding surface can be quickly obtained.

Description

Technical field[0001]The present invention relates to the field of robot grinding and processing, and more particularly to a weld mixed grinding method and system based on adaptive control.Background technique[0002]Traditional artificial polishing is monotonous because of weld grinding movement, workers are difficult to concentrate on work, leading to low work efficiency, poor reliability, and continuity can not maintain stability, and the quality of artificial grinding is mainly based on the level of workers' technical level, so it has stable Sex, especially for the welding industry. As the industry's application is more and more extensive, it is increasingly presenting the trend of industrial robots to work for artificial grinding.[0003]Industrial robots have grinding needed to be equipped with a spindle to ensure the finish of polishing at a higher grinding speed. For parts that are too high in weld, the grinding of the wear speed is done, which is huge for the grinding tool, whi...
