Drill bit edge grinding assembly

Abstract

The invention discloses a drill bit edge grinding assembly. The drill bit edge grinding assembly comprises an edge grinding device and a measuring device, and the edge grinding device and the measuring device are used in cooperation. The edge grinding device comprises a connecting mechanism, a scale positioning mechanism and an auxiliary edge grinding mechanism, one end of the connecting mechanism is connected with the scale positioning mechanism, the auxiliary edge grinding mechanism is arranged on the scale positioning mechanism, and the scale positioning mechanism is used for adjusting the circumferential angle or the axial position of the auxiliary edge grinding mechanism. The auxiliary edge grinding mechanism comprises a first edge grinding piece, a second edge grinding piece and an auxiliary piece, and the first edge grinding piece and the second edge grinding piece are arranged on the auxiliary piece. The drill bit edge grinding assembly has the beneficial effects that by aiming at the difficulty of manual edge grinding, the design concept that the edge grinding device and the measuring device supplement each other is adopted, edge grinding is more accurate and more efficient, personal experience accumulation is not needed, a green hand can grind a sharp and qualified drill bit, and the measuring precision is higher.

Description

technical field [0001] The invention relates to the technical field of sharpening, in particular to a drill bit sharpening assembly. Background technique [0002] The drill bit is the core part of various drilling tools, and the main cutting edge of the drill head is the core of each drill bit. The single main cutting edge of each drill bit forms a certain angle with the axis of the drill bit, which is called the main deflection angle in the industry. Different drill bit types have different specific standard angles for the main deflection angle. A qualified and sharp drill bit needs to meet two conditions at the same time: the angle of the first main cutting edge main deflection angle meets the standard angle requirements, and the second main cutting edge has symmetry with the axis line of the drill bit. [0003] After the drill bit is passivated, it must be sharpened before it can be used continuously. In the traditional manual sharpening technology, the drill bit is use...

Problems solved by technology

[0003] After the drill bit is passivated, it must be sharpened before it can be used continuously. In the traditional manual sharpening technology, the drill bit is used to sharpen on the grinding wheel, and then the other side is sharpened. The angle angle depends entirely on personal experience to grasp the angle between the drill bit and the grinding wheel, and the length of the main cutting edge of the drill bit depends entirely on visual inspection, sample, calipers, etc., so there are technical difficulties recognized by the industry in manual sharpening of the drill bit--First, the drill bit The two main deflection angles are difficult to be equal, and the length of the main cutting edge is difficult to be equal. When the length of the main cutting edge is not equal, the main cutting edge on both sides of the drill loses the symmetry with the axis of the drill; second, measure the sharpening of the drill Effect, the measurement accuracy of the existing method is too low
