Technical Field

[0001] This utility model belongs to the field of mechanical processing technology, specifically relating to a drill bit edge cleaning machine for large shank and small cutting edge. Background Technology

[0002] Drill bits are one of the most commonly used cutting tools in industrial production. They can drill holes in various metal materials, such as copper, cast iron, and steel, as well as various non-metallic materials, such as concrete, bricks, and plastics. Therefore, they have a very wide range of applications.

[0003] During the processing of drill bits, they need to be ground and cleaned. Existing edge cleaning machines use a material box for feeding. However, when dealing with small drill bits with a large shank and small cutting edge (i.e., a large tail and a small head), jamming occurs during feeding due to the special structure of the drill bit. Manual feeding is required, and each machine needs to be supervised by a worker, which greatly reduces work efficiency and increases labor costs. Therefore, it cannot meet the current requirements.

[0004] Therefore, the above-mentioned problems should be considered and solved during the edge cleaning process of large shank small cutting edge drill bits. Utility Model Content

Then, the drive motor 14 in the pushing assembly is started, causing the push rod 9 to advance forward, pushing the drill bit into the positioning table 12 within the positioning table 11. The positioning cylinder 33 is started, driving the shift fork 12 to press the positioning rod 11 against the drill bit for positioning. Then, the moving mechanism in the grinding assembly is started, driving the slide plate 25 to move via the moving screw 22, which in turn moves the grinding wheel 19. Move to the grinding station, and then the grinding wheel 19 grinds and cleans the drill bit, removing burrs, oxide layers or other defects from the surface of the drill bit. After the cleaning is completed, start the drive cylinder 7, which moves the pusher 3 to move outward, so that the feed chute 8 avoids the collection hopper 13. Then start the ejector assembly, which pushes the drill bit out through the ejector rod 27, so that the drill bit falls directly into the collection hopper 13. Then start the drive cylinder 7 again to reset the pusher 3, so that the discharge end of the feed chute 8 is aligned with the positioning groove 12, and the next round of cleaning can be carried out.
