Abstract
The invention belongs to the field of diesel engine part cutting and particularly relates to an adjustable eccentric reverse scraper. The reverse scraper comprises a cylindrical scraper body, a scraper handle used for being connected with a reverse scraper machine head is arranged at one end of the scraper body, and a scraper rod detachably connected to the scraper body and a tool bit are arranged at the other end of the scraper body. The scraper rod is adjustably arranged relative to the scraper body in the radial direction. The size of a bottom hole and the reverse scraping size can be adjusted by replacing various scraper rods. The eccentric amount of the reverse scraper tool bit is adjusted through a structure similar to a fine boring cutter so as to fine adjust the reverse scraping size, accordingly reverse scraping holes in various sizes can be machined through one reverse scraper, and cutter cost is greatly reduced.
