Description
Technical field
The utility model relates to a kind of metal cutting tool automatic protractor, belongs to machining measurer technical field.
Background technology
In metal cutting processing or metal cutting teaching, often to check the geometric angle on the cutter of workman or student's sharpening, current inspection method is to make one to check angular templet, its geometric angle of repeated measurement on the cutter of crossing at sharpening with model, with the naked eye read by rule of thumb its geometric angle numerical value, the original backwardness of method of this measurement metal cutting tool geometric angle, measuring process is slow, measurement data is inaccurate, and it is tired that gauger also feels more.
Summary of the invention
The purpose of this utility model is just to provide a kind of metal cutting tool automatic protractor, for addressing the above problem.
The technical solution of the utility model is: a kind of metal cutting tool automatic protractor, comprise straight edge ruler, surface, index dial, pointer, table circle, leaf spring, median septum, bonnet, axle, weight, watchcase and cotter pilotage, straight edge ruler is connected with watchcase threadably, on watchcase left surface, median septum is set, on watchcase right flank, bonnet is set, table circle left surface is provided with surface, its right side is provided with annular internal channel, insert in described internal channel with the formula formula of living two uniform cotter pilotage one end, the other end and watchcase are affixed, on axle, with interference fit, be provided with from left to right pointer, index dial, leaf spring and weight, pointer and weight opposite direction, the two ends of axle are separately positioned in the center pit of surface and bonnet with the formula formula of living, on index dial, be evenly carved with the groove of 1 ° of the every lattice of a circle, leaf spring presses index dial, the inner convex platform of table circle is close on the index dial left side.
The beneficial effects of the utility model are: easy to use, measurement is rapid accurate.
Accompanying drawing explanation
Fig. 1 is the main TV structure schematic diagram of the utility model.
Fig. 2 is that cross-sectional view is looked on the utility model right side.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail, with reference to accompanying drawing 1, Fig. 2 is known, and a kind of metal cutting tool automatic protractor, comprises straight edge ruler 1, surface 2, index dial 3, pointer 4, table circle 5, leaf spring 6, median septum 7, bonnet 8, axle 9, weight 10, watchcase 11 and cotter pilotage 12, straight edge ruler 1 is connected with watchcase 11 threadably, on watchcase 11 left surfaces, median septum 7 is set, on watchcase 11 right flanks, bonnet 8 is set, table circle 5 left surfaces are provided with surface 2, and its right side is provided with annular internal channel, and insert in described internal channel with the formula formula of living two uniform cotter pilotage 12 one end, the other end and watchcase 11 are affixed, on axle 9, with interference fit, are provided with from left to right pointer 4, index dial 3, leaf spring 6 and weight 10, pointer 4 and weight 10 opposite directions, the two ends of axle 9 are separately positioned in the center pit of surface 2 and bonnet 8 with the formula formula of living, and are evenly carved with the groove of 1 ° of the every lattice of a circle on index dial 3, leaf spring 6 presses index dial 3, and the inner convex platform of table circle 5 is close on index dial 3 left sides.Effect due to earth attraction, which inclined-plane no matter straight edge ruler 1 rest on, weight 10 vertically downward always, pointer 4 vertically upward always, during measurement, first hold up the utility model, straight edge ruler 1 is shelved in the plane of tested cutter, now weight 10 vertically downward, pointer 4 vertically upward, stem circle 5, make " 0 " on index dial 3 aim at pointer 4, then with straight edge ruler 1, rest on tested inclined-plane, now pointer 4 indication angles are exactly the geometric angle of tested cutter, the utility model can be surveyed the anterior angle of metal cutting tool, primary clearance, front clearance, tool cutting edge angle, auxiliary angle and cutting edge inclination, except metal cutting tool, also can do the measurement of other angles.
