Abstract
The utility model provides a tool for measuring center and diagonals of a drill bit by a vernier caliper. Without affecting the original functions of the vernier caliper, the new function is added by assembling few parts. The tool is characterized in that the drill bit to be measured is stably clamped by two V-shaped or semi-round clamping claws arranged on the vernier caliper; and two measuring sheets which are arranged on the clamping claws and have the same angle correspond to the two cutting blades of the drill bit after the angle reticles carved on the clamping claw and the measuring sheet correct the angle, thus being capable of measuring the error of the angle and the centering degree of the workpiece to be measured.
Description
Affiliated technical field: the utility model relates to the new function of vernier caliper, under the situation that does not change the vernier caliper original function, makes vernier caliper increase the angle at two cutting angles of a measurement drill bit and the function of centrad error by increasing the part parts.
Background technology: in machining, this common tool of drill bit is observed two cutting angles by naked eyes and whether centrad meets job requirement usually when reconditioning, and therefore, grasping this technical ability needs for a long time.And vernier caliper can be used for measuring distance, and the degree of depth can not be used for measuring the angle and the centrad at two cutting angles of drill bit.
Summary of the invention: in order to solve the workman when the coping drills, the dependence naked eyes observe two cutting angles and whether centrad meets job requirement, the inconvenience that need could grasp for a long time makes vernier caliper increase by one by mounting portion parts on vernier caliper and measures the angle at two cutting angles of drill bit and the function of centrad error.
The utility model provides the new technology at a kind of vernier caliper amount bit central diagonal angle.Concrete technical scheme is: install two respectively and measure sheet on vernier caliper chi body and slide calliper rule movable part, portrayal is corresponding with the measurement sheet on vernier caliper chi body, the indication measurement sheet is adjusted the scale mark of angle, after adjusting to the operating angle that needs, tighten vernier caliper chi body and measure the screwed register pin that is connected between the sheet, make vernier caliper chi body and measure the angle that maintenance needs between the sheet constant, reasonable mobile slide calliper rule movable part, make the measurement sheet that is installed on the slide calliper rule movable part, pass two holes of measuring the same diameter on the sheet by removable pin, because vernier caliper chi body and slide calliper rule movable part are parallel constructions, two are measured sheet is same size, equate according to two limits of isosceles triangle, the principle that two angles of its correspondence also equate, then vernier caliper chi body with measure sheet, the slide calliper rule movable part equates with the angle of measuring between the sheet, tighten the slide calliper rule movable part and measure the screwed register pin that sheet is connected, take off removable pin, make vernier caliper chi body and measure sheet, the slide calliper rule movable part becomes a relative integral body separately with the measurement sheet.Promote the slide calliper rule movable part then, stablize tested drill bit with V-arrangement on vernier caliper chi body and the slide calliper rule movable part or semicircle clamping, and bur slowly, make two measurement sheets corresponding with two cutting angles of drill bit respectively, by slit between the two, can understand the angle of measured workpiece and the error of centrad, and revise again, up to meeting job requirement.
The beneficial effects of the utility model are: the user practised by very short time, just can grasp the technology of the abrasive drilling head that could grasp for a long time by naked eyes, and accuracy was better than the drill bit that naked eyes grind.
Description of drawings:
When figure one is correcting measuring sheet angle, the figure of relative position between each parts;
Figure two is when measuring drill bit, the figure of the relative position between each parts;
1: vernier caliper chi body.2: the slide calliper rule movable part.3: measure sheet.4: measure sheet.5: removable pin.7: web member 1, the register pin of part 3.8: web member 2, the register pin of part 4.
Embodiment: on vernier caliper chi body spare 1 and slide calliper rule movable part bulk-breaking 2, install two respectively and measure sheet spare 3, part 4, portrayal is corresponding with measurement sheet spare 3 on vernier caliper chi body spare 1, indication measurement sheet spare 3 is adjusted the scale mark of angle, after adjusting to the operating angle that needs, tighten vernier caliper chi body spare 1 and measure the screwed location pin member 7 that is connected between the sheet spare 3, make vernier caliper chi body spare 1 and measure the angle that maintenance needs between the sheet spare 3 constant, reasonable mobile slide calliper rule movable part bulk-breaking 2, make the measurement sheet spare 4 that is installed on the slide calliper rule movable part bulk-breaking 2 by activity pin member 5, pass and measure sheet spare 3, measure the hole of the same diameter on the sheet spare 4, because vernier caliper chi body spare 1 and slide calliper rule movable part bulk-breaking 2 are parallel constructions, measuring sheet spare 3 and measuring sheet spare 4 is same sizes, equate according to two limits of isosceles triangle, the principle that two angles of its correspondence also equate, then vernier caliper chi body spare 1 with measure sheet spare 3, slide calliper rule movable part bulk-breaking 2 equates with the angle of measuring between the sheet spare 4, tighten slide calliper rule movable part spare 2 and measure the screwed location pin member 8 that sheet spare 4 is connected, take off activity pin member 5, make vernier caliper chi body spare 1 and measure sheet spare 3, slide calliper rule movable part bulk-breaking 2 becomes a relative integral body separately with measurement sheet spare 4.Promote slide calliper rule movable part spare 2 then, stablize tested drill bit with V-arrangement or semicircle clamping on vernier caliper chi body spare 1 and the slide calliper rule movable part bulk-breaking 2, and bur slowly, allow and measure sheet spare 3, it is corresponding with two cutting angles of drill bit respectively to measure sheet spare 4, by slit between the two, can understand the angle of measured workpiece and the error of centrad, and revise again, up to meeting job requirement.
