Description

Technical Field

[0002] A twist drill is a tool that drills round holes in workpieces by rotating relative to a fixed axis. It is named because its chip groove is spiral and resembles a twist. Before production, the twist drill can be put into use after the drill part is ground with a grinding wheel. In order to reduce the annealing and lowering of the hardness of the twist drill after grinding, grinding oil is usually applied to the outside of the twist drill for treatment.

[0003] A patent document with publication number CN218132875U discloses a drill blank grinding oil coating tool for twist drill bit production. The drill blank grinding oil coating tool for twist drill bit production is configured to slide relative to an extension block through a mounting seat, thereby enabling the spacing between the two coating brushes to be adjusted. A cam is configured to cooperate with a connecting rod to drive the slider to move, and a spring is configured so that the two coating brushes can be relatively close to each other under normal use, and can achieve the effects of pressure separation and bonding. However, the drill blank grinding oil coating tool for twist drill bit production lacks a structure for fixing the twist drill bit, so it is necessary to manually pick up the drill bit to coat the twist drill bit, and the operator can only coat a small number of twist drill bits at a time. When a large number of twist drill bits need to be coated, the overall processing time is longer. This method increases the labor intensity of the operator and reduces the efficiency of coating the twist drill bit. Therefore, a drill blank grinding oil coating tool is needed to solve the above problems. Utility Model Content
