Abstract
The utility model discloses a quick twist drill angle detection ruler, belongs to a mechanical measuring tool, and particularly relates to a detection device for the angle of a twist drill and the length of a main cutting edge. The quick twist drill angle detection ruler has the characteristics that: the detection ruler is formed through the connection of a horizontal ruler and a tilted ruler; the included angle alpha of the horizontal ruler and the tilted ruler is an obtuse angle; a length graduation ruler with the length graduations is fixed on the horizontal ruler; and the zero point of the graduations is arranged at the crossing point of the horizontal ruler and the inner side of the tilted ruler. The quick twist drill angle detection ruler has the advantages of novel design, simple and reasonable structure, and low manufacturing cost, and is easy to manufacture and reliable and convenient to use, can quickly and accurately detect the angle of the twist drill and the length of the main cutting edge, and creates the condition that the two parameters of the main cutting edge are uniform. The cutter grinding time is shortened, and the working efficiency is improved. The cutter grinding precision and the pass percent of the drill are improved. The drilling precision of the drill after being grinded is good, the service life of the drill is prolonged, and the consumption is reduced.
Description
Technical field
The utility model belongs to mechanical measurer, relates in particular to auger bit angle and main cutting edge device for detecting length.
Background technology
The drilling machine cut, the easy blunt of auger bit angle, wearing and tearing need be carried out again sharpening and could continue to use.Current, drill sharpening is to grind its main cutting edge length and drill bit angle by hand by the operative employee.Behind the drill sharpening, main cutting edge length and drill bit angle are only judged with operative employee's visual inspection and experience.Its defective is: the sharpening time is long, and work efficiency is low; Drill bit angle behind the sharpening is incorrect, and main cutting edge is uneven in length, and when causing auger shell line bottom outlet, the scope of thread Pilot hole diameter overshoot usually takes place and scraps; Drilling deep hole, since two main cutting edge length differences, the resistance to cutting F of workpiece
1, F
2Along drill bit main cutting edge distribution angle difference, the drill bit run-off the straight causes drill center to depart from; Irrational drill bit angle parameter is accelerated bit wear, shortens cutter life and reduces, and consuming increases.Serious hope can have a kind ofly can detect the pick-up unit that auger bit has related parameter.
Summary of the invention
In order to overcome the defective that prior art exists, the purpose of this utility model provides a kind of auger bit angle fast detecting chi, detects auger bit angle and main cutting edge length quickly and accurately, improve sharpening precision and qualification rate, save time, improve work efficiency, prolong drilling life of bit.
Auger bit angle fast detecting chi, characteristics are: this detection ruler is connected and composed by crossfoot and bevel, and according to the regulation of auger bit angle, the angle α of crossfoot and bevel becomes the obtuse angle; The length rule that is provided with the length scale is fixed on the crossfoot, and " O " point of scale is located at the intersection point place of crossfoot and bevel inner edge.To measure the angle of main cutting edge and drill bit shaft center line, measure main cutting edge length.
The utility model further improves, described crossfoot and bevel angle α=and 118 °.
The utility model further improves, and described length rule stickup/rivet is fixed on the crossfoot.
The utility model further improves, and described length scale directly is engraved on the crossfoot face.
The utility model further improves, and the minimum calibration unit of described length scale is 0.2mm.
During detection, drill bit is against bevel, and main cutting edge is aimed at " O " point of the length rule of crossfoot and measured a main cutting edge earlier, and then uses with sample prescription and measure another main cutting edge.Limit edging side, up to two main cutting edge length with till angle is consistent.
Advantage is: novel, simple and reasonable for structure, to make easily, and cost is low; Easy to use, reliable, can detect auger bit angle and main cutting edge length quickly and accurately, and be that two main cutting edge parameters are agreed and created condition; Shorten the sharpening time, improved work efficiency; Improved drill sharpening precision and qualification rate, the Drilling Operations precision is good behind the drill sharpening, has prolonged drilling life of bit, has reduced consumption.
Description of drawings
The utility model is described in further detail for the contrast accompanying drawing below.
Fig. 1 is an auger bit angle fast detecting chi structural representation.
Embodiment
As seen from Figure 1, auger bit angle fast detecting chi is to be connected and composed by crossfoot 1 and bevel 2, establishes through hole (not marking among the figure) on the crossfoot 1 chi face, and the length rule 3 that has length scale 4 is fixed on the crossfoot 1 by rivet 5.118 ° of the angles of the inner edge of crossfoot 1 and bevel 2 (being the relative edge), " O " point of length scale is located at the intersection point place of crossfoot 1 and bevel 2 inner edges.
Claims (4)
1. auger bit angle fast detecting chi is characterized in that this detection length is connected and composed by crossfoot (1) and bevel (2), and crossfoot (1) becomes the obtuse angle with the angle α of bevel (2); The length rule (3) that is provided with length scale (4) is fixed on the crossfoot, and " O " point of length scale is located at the intersection point place of crossfoot and bevel inner edge.
2. auger bit angle fast detecting chi according to claim 1 is characterized in that described crossfoot (1) and bevel (2) angle α=118 °.
3. auger bit angle fast detecting chi according to claim 1 is characterized in that described length rule (3) stickup/rivet is fixed on crossfoot (1) the chi face.
