Abstract

The invention discloses a scraper discharger for plane scraping of a fitting bolt, and belongs to the technical field of ship construction. The scraper discharger comprises a scraper discharger body and a positioning clamp. The scraper discharger body is in a cylinder shape. A conical handle is arranged at the upper end of the scraper discharger body. A protruding strip is arranged on the top faceof the conical handle. An annular groove is formed in the lower end of the scraper discharger body. The positioning clamp is arranged in an annular groove of the scraper discharger body in a sleevedmanner. The top face of the positioning clamp is perpendicular to the center line of the scraper discharger body. A first key groove is formed in the lower end of the side face of the scraper discharger body. The first key groove is arranged above the annular groove. The positioning clamp is arranged in the annular groove, loosening disengaging of the positioning clamp due to high-speed rotation and scraper rotation are avoided, and safety is high. The top face of the positioning clamp is perpendicular to the center line of the scraper body, the bearing force of the positioning clamp to the scraper is uniform, and the situation that in the scraper scraping process, inclination happens, and consequently the scraping precision is reduced is prevented.

Description

technical field [0001] The invention belongs to the technical field of shipbuilding, and in particular relates to a scraper used for scraping flat surfaces of closely fitted bolts. Background technique [0002] The installation of equipment in many industrial fields has high technical requirements. When the equipment is positioned, it needs to be positioned with tight fitting bolts. There should be no slight deviation. After the tight fitting screw holes are processed, the planes at both ends must be perpendicular to the screw holes. For scraping operations, in the prior art, it is often necessary to install a scraping row at the bottom of the pneumatic drill, and a scraper is installed on the scraping row to perform scraping operations. In the process of high-speed rotation, the scraper and the scraper are easy to fall off and cause accidents, and the cooperation between the scraper and the scraper is not tight enough, resulting in low scraping accuracy.
