Abstract

The invention relates to a drill cutter grinding machine and a fixture. An adjustable column in a fine turning machine is arranged on the outside of a grinding disk. The upper end of the grinding disk is provided with a pointer, and the lower end is articulated with the column shaft. A fixing column is arranged on the inner side the grinding disk. The upper ends of the two columns are connected with each other through a fine turning bolt. One end of the mobile platform on the operating platform is articulated with an adjustable sleeve through a fastening screw. The adjusting high gear inside the mobile platform is meshed with the rack on the adjustable column. The adjustable lever on the lower part of the mobile platform is movably connected with a regulating plate. The mobile platform is also provided with a slideway. A movable platform is arranged on the slideway. The fixing board of a fixture seat is arranged on the movable platform. And the upper part of the movable platform is also provided with the fixture seat. A vertical shaft is arranged on one side of the fixture seat. The upper part of the vertical shaft is articulated with a fixture pressure plate. The inner side of the vertical shaft seat on the lower part of the vertical shaft is provided with a pitch regulating gear. The grinding machine has simple structure, high grinding precision and less grinding times, which can prolong the service life of the cutter and improve the working efficiency. The special fixture matched with the grinding machine has great locking force and wide application.

Description

technical field [0001] The invention relates to a grinding tool, in particular to a drill bit milling cutter sharpening machine and a fixture. Background technique [0002] The traditional method of grinding milling cutters and drills is to manually grind the blade or drill against the grinding wheel, relying on skilled techniques and precise eyesight. This grinding technique is not easy to master and requires workers to learn and work for a long time Practice, the grinding accuracy is low, resulting in low machining accuracy and slow speed of the workpiece, and there are also the following defects: [0003] 1. Small angles such as the rake angle and front angle of the drill bit are not easy to grasp, which will cause drilling failure or easy edge chipping; [0004] 2. The main cutting edge is asymmetrical, and the cutting edge is uneven. Due to the uneven force during work, the machined parts vibrate, which increases the wear of the tool and parts, and the machining accura...
