Abstract
The utility model discloses a multifunctional twist drill cutter sharpening measuring instrument. Main points of the technical solution are that the multifunctional twist drill cutter sharpening measuring instrument is composed of two inclined rulers and an angle ruler, the two inclined rulers are hinged at the middle part of a base surface of the angle ruler through a screw, the angle ruler is semi-circular and provided with graduation lines of 0 DEG-180 DEG, one end of the inclined ruler is provided with graduation lines, the other end is a pointer-shaped measuring ruler, and the pointer-shaped measuring ruler points to the graduation lines of the angle ruler. The multifunctional twist drill cutter sharpening measuring instrument is simple in structure and convenient to use, and facilitates beginners to better master the cutter sharpening technology of a twist drill more quickly, solves the teaching difficulty of teachers to a great degree, reduces the learning difficulty of students at the same time, improves training interests of the students, and can be used by students in a major of machinery in various middle and high vocational colleges and training institutions.
Description
Technical field
The utility model relates to a kind of measurement mechanism of mechanical part, is specifically related to a kind of Multifunctional spiral drill sharpening measuring appliance.
Background technology
at present in teaching or training, for this problem of twist drill bit sharpening, adopt of teacher allows the student go to observe with eyes more, but just started to contact the sharpening problem of twist drill due to the student, structure to twist drill, it is imperfect that the purposes of each several part and characteristics are all understood, so modal when training is exactly can not detect after the twist drill sharpening finishes, whether the drill bit of not knowing own sharpening meets the requirements, if directly be clipped in test drilling on drilling machine, the undesirable drill bit sharpening again that just need to remove of result, so repeated multiple times, not only wasted a large amount of training times, also weigh and worn down to a great extent student's training enthusiasm.
Summary of the invention
The technical matters that the utility model solves has been to provide a kind of Multifunctional spiral drill sharpening measuring appliance simple in structure and easy to use.The technical solution of the utility model is: a kind of Multifunctional spiral drill sharpening measuring appliance, it is characterized in that mainly by two bevels and a bevel protractor, being formed, wherein two bevels are hinged on the basal plane middle part of bevel protractor by screw, described bevel protractor is the semicircle annular, the above is provided with 0 ° of-180 ° of scale mark, described bevel one end is provided with groove, and the other end is the scale mark of the dip stick orientation angle chi of the dip stick of pointer shape and this pointer shape.The utility model is simple in structure, and is easy to use, is convenient to the beginner and grasps the grinding technology of twist drill faster and betterly, solved to a great extent teacher's the difficulty of giving lessons, and also alleviated student's difficulty of learning simultaneously, improved student's training interest.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Drawing explanation: 1, bevel, 2, bevel protractor, 3, screw.
Embodiment
Describe by reference to the accompanying drawings embodiment in detail.A kind of Multifunctional spiral drill sharpening measuring appliance, mainly by two bevels 1 and a bevel protractor 2, formed, wherein two bevels 1 are hinged on the basal plane middle part of bevel protractor 2 by screw 3, described bevel protractor 2 is the semicircle annular, the above is provided with 0 ° of-180 ° of scale mark, described bevel 1 one ends are provided with groove, and the other end is the scale mark of the dip stick orientation angle chi 2 of the dip stick of pointer shape and this pointer shape.By the different cooperation positions of three rulers, then with reaching following several function after screw-driving: after 1, can measuring the twist drill sharpening, two main cutting edges are placed on the centre of two bevels, whether qualifiedly just can detect drift angle 118o ± 2o; 2, can judge according to the scale on two corresponding bevels of main cutting edge whether two main cutting edges are isometric simultaneously; 3, rotate vertically twist drill, measure knife face after two of twist drills, rotate a bevel, can the angle corresponding according to the bevel finger tip detect the size of Back Clearance of Twist Drill sharpening numerical value; 4, measure the basal plane of face fit angle chi with bevel, whether the chisel edge angle that can measure twist drill is qualified.The utility model is simple in structure, and is easy to use, is convenient to the beginner and grasps the grinding technology of twist drill faster and betterly, solved to a great extent teacher's the difficulty of giving lessons, and also alleviated student's difficulty of learning simultaneously, improved student's training interest.
