Problems solved by technology

[0002] When performing precision machining of metal parts, due to the extrusion of the cutting surface, burrs will be generated on the side of the cutting surface, which will affect the surface smoothness and precision quality of the workpiece
[0003] Most of the existing burr scraping devices are scraped by manual hand-held scrapers, which is very easy to cause scratches to fingers or scratches on the cutting surface, which has problems affecting accuracy and safety, and the efficiency is low. Due to the difference in the cutting surface of the workpiece in the device, the adaptability of the device is low. The surface processing burrs are generated on the side of the surface, and the drilling processing, the burrs are located at the upper and lower ports of the drilling hole.
[0004] To this end, a burr scraping device for precision machining and a scraping method are provided to solve the problem of adaptation and efficiency of the burr scraping device for precision machining

Embodiment 2

[0046] Embodiment 2: When the workpiece 14 is a drilling cutting surface, the burr is located at the drilling port, and the mounting block 5 is a ring frame, and the positioning of the workpiece 14 is realized by the limit extrusion of the cylindrical positioning block 16 and the fastening cover plate 8. Preliminary fixation, the mounting block 5 is squeezed by the positioning screw 7 to realize the horizontal sliding adjustment of the mounting block 5 on the guide rail 6, so that the burr port is located directly below the scraper 10;

[0047] The lifting column 3 rises to drive the scraping side to fit the scraper 10, and the fastening cover plate 8 presses the spring 11 to realize the fastening and fixing installation of the workpiece 14.

[0048] The driving device 4 adopts a rotating motor with a gear, and the motor drives the gear to mesh with the ring gear 19, so that the mounting block 5 rotates on the upper end of the slider 15, and realizes the circular rotation of th...
