Abstract
The utility model discloses a test technical field's shrink measuring apparatu, it is including measuring scale, dial plate, measuring staff and gear. A circular tube-shaped sleeve is fixed below a circular dial plate with uniform scales, a cylindrical measuring rod with a straight rack can slide in the sleeve, a shaft gear is meshed with the straight rack of the measuring rod, a plate gear is coaxial with the shaft gear, a central gear is meshed with the plate gear, and measuring heads are respectively fixed at one end of the sleeve and one end of the measuring rod. The utility model discloses can extensively be used for measuring linear shrinkage rate and shrinkage value when the object takes place to shrink.
Description
The utility model belongs to technical field of measurement and test, further relates to a kind of contraction measuring instrument of measuring the shrinkage factor and the shrinkage value of measured object.
The existing measurer that is used for the Measuring Object linear shrinkage uses omnipotent measurer the most commonly used such as vernier caliper, ruler, dial gauge, at first measures a length L during use on object
1, and mark, Measuring Object is shunk the former mark lengths variation back numerical value L in back again
2, use last length value L
1With contraction back length value L
2Difference be shrinkage value; With shrinkage value divided by raw footage value L
1Be shrinkage factor.Measuring process at first will be measured length, also needs then can obtain the result by mathematical formulae calculating.Operating personnel's workload is big, occurs miscount easily.
The purpose of this utility model is to provide the contraction that can directly show test results in a kind of on-line measurement measuring instrument.
The below that the utility model comprises surveyors' staff, dial plate, measuring staff and gear, have a circular dial plate of even scale is fixed with the tubular sleeve, the cylindrical measuring staff that has spur rack can slide in sleeve, the spur rack engagement of shaft gear and measuring staff, plate gear is coaxial with shaft gear, central gear and plate gear engagement, central gear and the plate gear engagement that has short pointer are equipped with Long pointer on the axle of central gear, and gauge head is separately fixed at sleeve one end and measuring staff one end.
Below in conjunction with accompanying drawing the utility model is further described.
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is a side view of the present utility model.
Fig. 3 is a principle schematic of the present utility model.
Fig. 4 is a surveyors' staff synoptic diagram of the present utility model.
The utility model comprises the gear in surveyors' staff, dial plate, measuring staff and the dial plate.The below that has the circle table body 4 of scale is fixed with tubular sleeve 9, the cylindrical measuring staff 3 that has spur rack can slide in sleeve 9, be separately fixed at cylindrical gauge head 1 of tip and the cylindrical gauge head 2 of tip that is fixed on the measuring staff 3 on the sleeve, be carved with 100 scales of even five equilibrium on the dial plate 6, the reading of result on dial plate 6 in long indicator 5 indication measurements, be carved with 3 scales of even five equilibrium on the fan-shaped dial plate 8, point to the short pointer 7 of dial plate 8.
Surveyors' staff is the rectangle cross section, and the two ends of scale are fixed with the cylindrical pressure head 13 of tip respectively, and the pressure head body diameter on the scale is 1.5 times of the cylindrical gauge head body diameter of tip on the contraction measurement instrument, and distance is 100mm between two pressure heads.
Principle of work of the present utility model is with straight-line displacement process tooth bar--the gear drive of measuring staff 3, changes angular displacement into.Among Fig. 3, spur rack 10 on the measuring staff 3 and the interior shaft gear Z of table body
2Engagement is with shaft gear Z
2Coaxial plate gear Z
3With central gear Z
1Engagement, central gear Z
1On Long pointer 5 is housed.Central gear and plate gear Z
4Engagement, plate gear Z
4On short pointer 7 is housed, therefore, when measuring staff 3 moves, make shaft gear Z
2And plate gear Z
3Rotate, at this moment central gear Z
1And the Long pointer on the axle 5 rotates the scale that points on the dial plate 6, plate gear Z
4On short pointer 7 also with central gear Z
1Rotate and rotate.Like this, shrinkage value and the shrinkage factor that just demonstrates testee rotated in the angular displacement of Long pointer and short pointer in other words on the dial plate.In order to eliminate the error that causes owing to gear clearance, by plate gear Z
4With the central gear engagement, making the gear pair in the whole gear train all is the single face engagement when rotating under the torsional moment effect that hairspring 11 produces.Spring 12 makes measuring staff get back to the origin-location when not measuring.
In use, at first on testee, extrude two mark pits or mark two gauge points with the cylindrical pressure head 13 of two tips on the scale, testee does not produce when shrinking, with two the tip cylindrical gauge head alignment mark pits or the gauge point that shrink on the measuring instrument, demonstrating shrinkage value and shrinkage factor on the dial plate is zero.After testee shrinks, distance between two mark pits or the gauge point diminishes, when aiming at two marks with the cylindrical gauge head of two tips on the contraction measuring instrument, measuring staff 3 inwardly slides and makes between two gauge heads that distance equates between distance and two marks, at this moment spur rack drive table body annular wheel makes pointer rotation on the dial plate on the measuring staff 3, demonstrates the shrinkage value and the shrinkage factor of testee.Every contraction 10% of testee or 10mm short pointer move 1 scale, and Long pointer moves 100 scales simultaneously.For example when measuring, short pointer points between 10 and 20, and Long pointer points to 5.65, and then the object shrinkage factor is 15.65%, and shrinkage value is 15.65mm.
The utility model shrinks used measurer with existing measurement such as slide measure, ruler etc. are compared, and has direct demonstration contraction value and shrinkage factor, and is easy, quick. With slide measure, when ruler equal length measurer is measured contraction, measure earlier the length that testee shrinks front and back, formulation calculates again. Use of the present utility model makes to measure to shrink directly reads the result, has reduced operating personnel's workload, and mistake and the error that may occur when having avoided formula to calculate have improved work efficiency and the degree of accuracy. The utility model certainty of measurement is higher, is 0.01mm.
Linear shrinkage ratio and contraction value when the utility model can be widely used in and measure object and shrink, testee can be inorganic material, organic material, metal material or composite, testee can be solid, mecystasis, the object of phase transition take place, testee is when dehydration or other physical reactions, as long as burn into fusing or destruction measuring instrument all can not measured in change procedure.
The utility model is specially adapted to pottery, brick-tile industry is measured object in dehydration, roasting The shrinkage phenomenon that produces in the burning process. The industries such as building materials, chemical industry, geology, agricultural all the contraction carried out in scientific research, production, the check of available this contraction measuring instrument measure.
