Counter-pull type polishing brush

Abstract

The invention discloses a counter-pull type polishing brush. The polishing brush is composed of a pull rod and a polishing brush body. The pull rod is cylindrical. The middle of the pull rod serves as a rod shaft (1). One end of the pull rod serves as a fixed end (3) which is used for being installed on a pneumatic drill or an electric drill in a clamped mode. The other end of the pull rod serves as a connecting end (2) connected with the polishing brush body. An internal thread is machined in the center of the connecting end (2). An external thread is machined at one end of a connecting rod (6) of the polishing brush body, and the external thread and the internal thread of the connecting end (2) of the pull rod are rotatably connected clockwise. The other end of the connecting rod (6) of the polishing brush body is connected with a cylindrical polishing head (4). Bristles (5) are arranged on the polishing head (4) and the connecting end face of the connecting rod (6). By means of the counter-pull type polishing brush, the problem that a dwell section is inconvenient to polish or cannot be polished is solved, the labor intensity of operators is relieved, the production efficiency is improved, and meanwhile the appearance quality of a product can be guaranteed. Most importantly, the application space of the counter-pull type polishing brush is large, and the counter-pull type polishing brush can be widely used for conducting paint removing treatment on the surfaces of parts in the assembling process of a rotorcraft or a fixed wing aircraft.

Description

technical field [0001] The invention is an anti-pull type grinding brush, which belongs to the technical field of product structure. Background technique, [0002] Since aircraft designers have requirements for electrical lapping of the airframe structure, it is a very common method to use rivets for electrical lapping in the aircraft assembly process to achieve electrical lapping of the airframe. The surface treatment of structural parts is usually to remove the paint layer on the surface of the parts by grinding, to expose the luster of the metal parts or to see the metal mesh of the laminate, and then implement rivet lap joints. At present, there are two main methods for removing paint on the surface of parts in order to realize the electrical lap of rivets: 1. Use fine sandpaper to manually polish the overlapping area of ​​the parts. Although the paint can be removed on the surface of the parts, the production efficiency is low. The quality is not guaranteed, which is n...
