Embodiment 1

[0045] A kind of drill edge grinding device, with reference to figure 1 , which includes a base 1, the base 1 is in the shape of a square plate, and four corners of the bottom surface are fixed with pads. In this embodiment, the base 1 is arranged in three places in a straight line.

[0046] refer to figure 1 with figure 2 , a servo motor 24 is fixed on each base 1, and a grinding wheel 2 is installed on the driving end of the servo motor 24. The central axis of the grinding wheel 2 is parallel to the base 1 , and the grinding cilia 3 made of high-density polyethylene are evenly distributed on the outer peripheral side wall of the grinding wheel 2 . After the servo motor 24 is energized, it drives the grinding wheel 2 to rotate circumferentially.

[0047] refer to figure 1 with figure 2 One side of the base 1 is provided with a slide rail 41, and the top surface of the slide rail 41 is inclined downward away from the top surface of the base 1, that is, the long side of...

Embodiment 2

[0053] A kind of drill edge grinding device, with reference to image 3 , based on Embodiment 1, the difference between this embodiment and Embodiment 1 is that the grinding wheel 2 includes a coaxially sleeved wheel body 21 and a ring body 22, and the polishing cilia 3 are evenly distributed on the outer circumferential side wall of the ring body 22 . The inner peripheral sidewall of the ring body 22 is provided with three clamping blocks 221 , and the cross-sectional shape of the clamping blocks 221 is semicircular. The outer peripheral sidewall of the wheel body 21 is provided with a bayonet 211 for the clamping block 221 to snap into, and the end surface of the wheel body 21 is detachably mounted with a fixing plate 23 via a fixing bolt 231 . After the ring body 22 is sheathed on the wheel body 21 so that the clamping block 221 snaps into the bayonet 211 , the fixing plate 23 is attached to the end surface of the wheel body 21 and fixed by the fixing bolt 231 . The ring ...

Embodiment 3

[0055] A method for grinding a drill edge, using the drill edge grinding device of embodiment 1 to grind the edge 82 of the drill 8, specifically comprising the following steps:

[0056] P1, open servo motor 24, make servo motor 24 drive grinding wheel 2 to rotate with the rotating speed of 2800-3200rpm; The rotating speed of grinding wheel 2 can be adjusted according to the actual situation, and the rotating speed of grinding wheel 2 is 2800rpm in the present embodiment;

[0057] P2, clamp the drill bit 8 to be polished in the clamping groove 51 on the clamping block 5, so that the head end of the drill bit 8 faces the grinding wheel 2;

[0058] P3. Press the drill bit 8 to keep the drill bit 8 fixed on the clamping block 5, turn the clamping block 5 until the drill bit 8 deviates from the direction perpendicular to the axis of the grinding wheel 2, maintain the state of the drill bit 8, slide the slider 4 back and forth along the slide rail 41, and make the drill bit The hea...

Abstract

The invention discloses a drill bit cutting edge grinding device, and belongs to the technical field of drill bit machining. The drill bit cutting edge grinding device includes a base, a polishing wheel having the axis parallel to the base; polishing cilia made of a synthetic resin material that are uniformly distributed on the side wall of the outer circumference of the polishing wheel; a drivingdevice which is borne on the base and used for generating power to drive the grinding wheel to rotate circumferentially; a sliding block which is arranged in a sliding mode in the axial direction ofthe grinding wheel, and a drill bit clamping mechanism used for fixing a drill bit to be ground is arranged on the top face of the sliding block; and a dust collecting device which is used for collecting grinding chippings. The grinding device has the advantages that operation is easy and safe, the grinding amount is easy to control, and the grinding condition is convenient to check in real time.The invention further aims to disclose a drill bit cutting edge grinding method applying the drill bit cutting edge grinding device. The drill bit cutting edge grinding method has the advantages of being easy and convenient to operate and safe. In addition, the invention further discloses a drill bit, and by using the method to grind the cutting edge of the drill bit, the cutting edge of the drillbit is sharp, not prone to breakage and longer in service life.

Description

technical field [0001] The invention relates to the technical field of drill bit processing, more specifically, it relates to a drill bit edge grinding device, a drill bit edge grinding method and a drill bit. Background technique [0002] During use, the main edge and chisel edge of the drill will become blunted or even chipped as the number of uses increases, in order to protect the cutting edge and extend the service life of the drill. After the drill bit is processed and formed, it is often necessary to grind the main edge and the chisel edge of the drill bit, and form an arc-shaped edge of 1-3 wires at the edge, which does not affect the cutting sharpness of the edge, and can sharpen the edge play a protective role. [0003] At present, grinding the drill bit is often performed by a technical master using a grinder and grinding paper. The grinding process of the grinder is complex, with many operating procedures, it is difficult to control the grinding accuracy, and i...
