Description

Technical Field

[0001] The utility model relates to the technical field of mechanical processing, in particular to a drill bit grinding platform. Background Art

[0002] Drill bits are widely used in some manufacturing fields, especially in mechanical manufacturing. The quality of drill bits directly affects the quality of drilling. In some drilling situations with higher precision requirements, the requirements for drill bits are even more stringent. Drill bits will wear out after long-term use and need to be sharpened.

[0003] According to a drill bit grinding platform disclosed in Chinese patent publication number CN 220863465 U, it is proposed that the current drill bit grinding platform uses two arc plates to clamp the drill bit. When the drill bit diameter is small, the drill bit is not stably clamped between the two arc plates, which will cause shaking during the grinding process, which is not conducive to the grinding of the drill bit. The patent is passed by inserting the drill bit between the lower clamping plate and the upper clamping plate of the clamping mechanism, using the turning handle to rotate the fastening bolt, the fastening bolt moves downward, and pushes the guide plate and the upper clamping plate to move downward, so that the drill bit is pressed to the lower clamping plate by the upper clamping plate, and the drill bit is clamped and fixed by the upper clamping plate and the lower clamping plate. When the angle of the drill bit needs to be adjusted, the rotary positioning mechanism can be rotated to drive the connecting plate to rotate longitudinally, the insertion rod is inserted into the insertion hole, and the rotary positioning mechanism is positioned to limit the longitudinal angle of the clamping mechanism and the drill bit. The clamping mechanism is rotated, and the clamping mechanism rotates with the rotating screw as the center of the circle to adjust the lateral angle of the drill bit. Tightening the positioning nut can limit the rotation of the rotating screw. However, in actual use, the device needs to manually adjust the drill angle, and the adjustment position is fixed, which reduces the grinding efficiency.

[0004] To this end, we proposed a drill bit grinding platform to solve the problem that the above device requires manual adjustment of the grinding angle, which reduces the grinding efficiency. Utility Model Content
