Description

Technical Field

[0001] The utility model relates to the technical field of grinding drill processing, in particular to a secondary cutting edge processing device for high-strength grinding drill processing. Background Technique

[0002] A drill bit is a tool used to drill through holes or blind holes in solid materials and can also ream existing holes. Grinding drill bits are used in large quantities in the machinery industry and related industries for a long time, and are a kind of drilling tool with a large quantity and wide range. During the processing of drill bits, it is necessary to grind the secondary cutting edges.

[0003] The traditional regrinding method is that workers hold the drill bit by hand and grind the cutting edge part of the drill bit on the grinding disk. However, since the cutting edge part of the drill bit used for drilling PCBs is very small, it is difficult for the human eye to distinguish it. Therefore, problems such as drill breakage and drill bit damage are likely to occur due to excessive force or incorrect direction and angle during manual grinding of the drill bit.

[0004] In the patent document with the publication number CN206357001U, a drill bit cutting edge grinding device is proposed. The device body includes a control module, a grinding module, a microscope, a grinding rod, and a sliding platform. The grinding module is connected to the control module through a rotating motor. The grinding rod is arranged on the sliding platform through a bracket. One end of the grinding rod for clamping the drill bit is provided with a rotating clamping part that can rotate around the axis direction of the grinding rod. The sliding platform is connected to the device body through a platform cylinder. The microscope is arranged on the sliding platform and above the rotating clamping part so that the drill bit clamped in the rotating clamping part is always within the observation range of the microscope, and the drill bit can be accurately reground. Moreover, the force and angle during the regrinding process meet the structural requirements of the drill bit. Therefore, problems such as drill breakage and drill bit damage will not occur due to excessive force or incorrect direction and angle during regrinding of the drill bit, which is conducive to the secondary use of the drill bit.
