Abstract

The utility model discloses a rotary scraping cutter which comprises a cutter handle. The front end of the cutter handle is fixedly connected with a connecting sleeve. A cutter bar is movably arranged in the connecting sleeve. The connecting sleeve is movably connected with the cutter bar through a sliding bearing. The front end of the cutter bar extends out of an adjusting sleeve, and an elastic clamping barrel is arranged at the front end of the cutter bar and used for clamping a rotary scraper. Fixed connection of the cutter bar and the rotary scraper is achieved through a locking nut. The cutter bar can drive a sliding hinge pin on the cutter bar to axially slide in the sliding bearing. A machine tool spindle rotates to drive the cutter handle and the connecting sleeve to rotate, and the connecting sleeve rotates to drive the cutter bar and the rotary scraper to perform synchronous rotation through the sliding hinge pin. A blade of the rotary scraper is in contact with the machining face to achieve rotary scraping of the machining face. The rotary scraping cutter uses the machine tool spindle as a rotating power source and performs automatic scraping and precise machining on machine tool guide rail faces, standard flat plates, square boxes required to be scraped and other planes to enable the precision of the planes to be high.
