Mobile self-dust-suction continuous grinding and polishing machine for large equipment surface treatment

Abstract

The invention discloses a mobile self-dust-suction continuous grinding and polishing machine for large equipment surface treatment. The mobile self-dust-suction continuous grinding and polishing machine comprises a mobile base, a pneumatic mechanical arm and a self-dust-suction eccentric grinding machine; the pneumatic mechanical arm is movably assembled on the mobile base and comprises an assembling and positioning assembly and a pneumatic swinging arm assembly; and the self-dust-suction eccentric grinding machine is installed at one end of the pneumatic mechanical arm through a connecting rack structure. According to the mobile self-dust-suction continuous grinding and polishing machine for large equipment surface treatment, the pneumatic swinging arm and the self-dust-suction eccentricgrinding machine are installed on the mobile base, one person operates the machine to enable the machine to move along the outer contour of a machine body, the grinding process of various shape and hook face coherent portions of the machine body is continuously completed, the structure is simple and compact, programming is not needed, operation is flexible and convenient, standardized production is facilitated, the production efficiency and the machine body grinding surface quality are improved, environmental pollution is reduced to the maximum limit, and sufficient technical guarantees are provided for grinding and polishing of complex and irregular hook faces of the large machine body.

Description

technical field [0001] The invention relates to a polishing structure, which belongs to the technical field of grinding and polishing equipment, in particular to a mobile self-dusting continuous grinding and polishing machine for surface treatment of large equipment. Background technique [0002] The rapid development of my country's aviation industry, large-scale manufacturing of commercial aircraft, military aircraft, unmanned aerial vehicles and amphibians and other products, the aviation market is huge, and there are many types of aircraft and the shape of the fuselage is complex. For example, the C919 has a fuselage length of 38.9m and a wingspan of 35.8m; the length of the fuselage of a large passenger aircraft is generally in the range of 30-75m, and the most numerous 737 and A320 series have a fuselage length of about 34-38m and a wingspan of about 34m. The exhibition is about 80m, etc. In the manufacture and maintenance of the aviation industry, a large number of a...

Problems solved by technology

At present, most of these processes still rely on the workers to hold the grinding machine. The manual grinding and painting process takes up the most workers and the longest working hours.

This way of working not only causes serious pollution to the environment, but also causes permanent damage to the muscles and nerves of the operator's fingers, wrists and arms, thereby reducing production efficiency and is not conducive to standardized production, especially for the polished surface of the complex shape of the outer contour of the fuselage especially the quality

[0003] Judging from some prior patent documents disclosed at present, no relevant particularly effective system equipment and polishing methods have been found, such as the following prior documents: 1. Application Publication No. CN107009236A "Gantry for Polishing Large Parts of Rail Train Car Body" 2. Authorized announcement number CN202640114U "an adjustable large-scale polishing equipment"; 3. Authorized announcement number CN204527157U "a special equipment for visual car body polishing"; 4. Authorized announcement number CN206070264U "open abrasive belt Rail high-speed grinding car"
