Summary of the invention
The technical problem to be solved is to provide a kind of engineering flatness measuring instrument and measuring method thereof, and it can have object to intercept, and can realize the measurement of planeness at any time.
The present invention solves above-mentioned technical problem by following technical proposals: a kind of engineering flatness measuring instrument, it includes base, wind spring, the first gear, the second gear, Winding board, one end of wind spring is fixed on base, one end of wind spring and the first gear connect firmly, first gear and the engagement of the second gear, Winding board and the second gear connect firmly.
Preferably, the side of described Winding board is provided with slide block screw rod and slide block, and one end of slide block screw rod is connected with whorl of base, slide block and being slidably connected.
Preferably, the diameter of described first gear is more than the diameter of the second gear.
Preferably, it is screwed between described base and a shell.
Preferably, described wind spring, the first gear, the second gear, Winding board, slide block are positioned at shell.
Preferably, described Winding board is connected with base by a rotating shaft.
Preferably, described slide block there is line outlet.
The present invention also provides for the measuring method of a kind of engineering flatness measuring instrument, it is characterised in that this measuring method adopts above-mentioned engineering flatness measuring instrument, and this measuring method comprises the following steps:
Step one, under original state, measures line and is completely wound around on Winding board;
Step 2, pulls open two testers during measurement, measure line and pull out from two ends line outlet;
Step 3, drives Winding board to rotate; Winding board and the second gear connect firmly, and the second gear rotates with Winding board;
Step 4, the second gear and the engagement of the first gear, drive the first gear engagement, and because the first gear is bigger than the second gear, therefore the rotation number of turns of the first gear is fewer than the second gear;
Step 5, the second gear delivers torque to the first gear, then the first pinion rotation, drives wind spring rotating shrinking, discharges under the effect of power in wind spring elasticity, measures line and is straightened.
The actively progressive effect of the present invention is in that: engineering flatness measuring instrument of the present invention can have object to intercept, and can realize the measurement of planeness at any time, additionally facilitates and carries.

Detailed description of the invention
Present pre-ferred embodiments is provided, to describe technical scheme in detail below in conjunction with accompanying drawing.
As shown in Figures 1 to 4, engineering flatness measuring instrument of the present invention includes base 1, wind spring the 2, first gear the 3, second gear 4, Winding board 5, one end of wind spring 2 is fixed on base 1, one end of wind spring 2 and the first gear 3 connect firmly, first gear 3 engages with the second gear 4, first gear 3 is positioned at the top of wind spring 2, and Winding board 5 and the second gear 4 connect firmly. The side of Winding board 5 is provided with slide block screw rod 7 and slide block 6, threadeds with base 1 in one end of slide block screw rod 7, and slide block 6 and slide block screw rod 7 are slidably connected. The diameter of the first gear is more than the diameter of the second gear. Being fixed by screw 9 between base 1 and a shell 8, wind spring the 2, first gear the 3, second gear 4, Winding board 5, slide block 6 are positioned at shell 8. Having line outlet 10 on slide block 6, line outlet can use heat-shrink tube as outlet lining, measures line 11 and is wrapped on Winding board 5, passes through line outlet and be connected with another tester. Winding board 5 is connected with base 1 by a rotating shaft 12, and rotating shaft can be freely rotatable.
Base can be anodized aluminum pedestal, and die cast is lightweight, and wearability is good, and rigidity is big, and device measuring error is little, and easy to assembly. The compact conformation of wind spring, elastic contractile force is big, except realizing at ordinary times except coiling function, moreover it is possible in use as the take-up device of measurement line. First gear and the second gear realize big speed ratio so that the Winding board spiral number of turns is many, and measurable size range is more extensive. First gear, the second gear can adopt nylon material, and weight has gently, and tensile strength is big, and hardness is high, the features such as wearability is good, and self lubricity is strong, and relative inexpensiveness. Winding board can adopt plastic material, lightweight, and intensity is good, and cost is low. Slide block adopts spiral, it is easy to control certainty of measurement, and line outlet can use heat-shrink tube as outlet lining, and line damping is non-normally low. Easy accessibility of the present invention, volume is little, lightweight, is convenient for carrying, and except shell need outside die casting, other substantially can be chosen general part freely assemble according to measuring area requirement, convenient and practical.
The measuring method of engineering flatness measuring instrument of the present invention comprises the following steps:
Step one, under original state, measures line and is completely wound around on Winding board;
Step 2, pulls open two testers during measurement, measure line and pull out from two ends line outlet;
Step 3, drives Winding board to rotate; Winding board and the second gear connect firmly, and the second gear rotates with Winding board;
Step 4, the second gear and the engagement of the first gear, drive the first gear engagement, and because the first gear is bigger than the second gear, therefore the rotation number of turns of the first gear is fewer than the second gear;
Step 5, the second gear delivers torque to the first gear, then the first pinion rotation, drives wind spring rotating shrinking, discharges under the effect of power in wind spring elasticity, measures line and is straightened.
The present invention can be carried out various remodeling and change by those skilled in the art. Therefore, present invention covers the various remodeling in the scope falling into appending claims and equivalent thereof and change.
