Preferably, a positioning shaft is provided on an outer wall of the body.
Preferably, the device further comprises a movable base, and the body is fixedly connected to the movable base.
Preferably, the number of the angle positioning blind holes is four, and the four blind holes are uniformly distributed on the periphery of the axis of the connecting shaft.
Preferably, the axis of the angle positioning through hole is parallel to or coincident with the axis of the angle positioning blind hole, the axis of the angle positioning through hole is parallel to the axis of the connecting shaft, and the distance from the axis of the angle positioning through hole to the axis of the connecting shaft is equal to the distance from the axis of the angle positioning blind hole to the axis of the connecting shaft.
In the above technical solution, the body is the foundation structure of the utility model, and mainly plays a role in supporting and bearing; the connecting shaft is used for connecting the rotating handle and the drill chuck and is used for adjusting the angle of the drill chuck when the rotating handle is screwed; the drill chuck is used for clamping and fixing the stepped drill bit; the angle positioning blind holes at the rear end of the body are provided with a plurality of angle positioning blind holes, and when the angle positioning through holes are overlapped with certain angle positioning blind holes by screwing the rotating handle, the angle positioning pins in the angle positioning through holes can be pushed into the angle positioning blind holes, so that the angle can be locked.
The utility model discloses when using, on the ladder drill centre gripping that will treat the sharpening was fixed in the drill chuck, utilized the emery wheel to carry out the grinding to the big sword in one side of ladder drill, the grinding is accomplished the back, rotates 180 degrees with rotatory handle, makes the big sword of opposite side accept the grinding wheel grinding, accomplishes the sharpening of both sides, can guarantee the symmetry.
On the basis of the technical scheme, the base with the angle and capable of translating along the X direction can be further matched for use. When the stepped drill bit is used, after the stepped drill bit is clamped by a drill chuck, the cutting edge to be ground is visually observed to be at a right angle with the grinding wheel, the angle base is adjusted to a required angle, the base is moved to carry out grinding in the X direction, the tool wheel is rotated by 180 degrees after grinding of one side is finished, the cutting edge of the other side is at a right angle with the grinding wheel, and grinding is finished.
The tool can ensure the centrality of the sharpening drill and the symmetry of cutting edges at two sides, ensure that the grinding surfaces are strictly positioned on the same plane, and fully ensure the quality of drilling step holes. Use the utility model discloses, can be on ordinary abrasive machine sharpening big sword cutting edge to guarantee the symmetry of sharpening angle and both sides blade, thereby ensured the concentricity and the sharpening quality in drilling hole.
