In the industrial production, the straight length that vernier caliper is mainly used in object is measured, and such as, the straight length of workpiece diameter or external diameter is measured; In addition, the blade of vernier caliper is generally inflexible hard blade, is not easy to carry and take care of.When carrying out the length of curve measurements such as workpiece arc length when needs, cannot be realized by the vernier caliper with hard blade.
The vernier caliper that prior art adopts the vernier caliper with tape body to substitute to have hard blade is to meet the needs of length of curve measurement, this vernier caliper measures internal diameter by being positioned at the square internal measure-hand of tape with it, external diameter is measured by the external pelivimetry pawl be positioned at below blade, but, when being inconvenient to move parts to be measured, in order to make convenient reading, accurately, need the measuring claw above by vernier caliper to be fixed on parts to be measured and measure external diameter, or the measuring claw below vernier caliper is fixed on parts to be measured and measures internal diameter, at this moment, adopt existing flexible vernier caliper cannot realize measuring needs, measure inconvenient.And the blade of the vernier caliper with tape body is thinner, in measuring process, can there is relative motion in vernier and the tape body of vernier caliper, affect measuring accuracy.
Utility model content
Of the present utility modelly to solve existing flexible vernier caliper and not only can not meet and measure convenient but also meet the problem measuring precise requirements.
For this reason, the utility model adopts following technical scheme:
A kind of flexible vernier caliper, comprise the graduated tape body of band and vernier, vernier is sliding to be inserted in it tape, one end place of tape body is provided with fixation measuring pawl, vernier is provided with slip measuring claw, fixation measuring pawl comprises fixation measuring pawl and lower fixation measuring pawl, and slip measuring claw comprises slip measuring claw and lower slider measuring claw; Upper fixation measuring pawl and upper slip measuring claw, and lower fixation measuring pawl and lower slider measuring claw are symmetrical all mutually; Upper fixation measuring pawl, on slide on measuring claw, lower fixation measuring pawl and lower slider measuring claw and be provided with inside dimension measuring surface and outside dimension measuring surface; Spring leaf is provided with between tape body and vernier; Vernier is also provided with trip bolt; All magnetic sheet is embedded with in each inside dimension measuring surface or outside dimension measuring surface.
In preferred scheme, upper fixation measuring pawl, upper slip measuring claw, lower fixation measuring pawl and lower slider measuring claw are provided with locating piece.
In preferred scheme, tape body institute is with a scale is millimeter scale and centimeter scale; Or be graduated in English.
The utility model remains the advantage of existing flexible vernier caliper, the rigidity blade of traditional vernier caliper is replaced with the blade of flexible any radian, and blade length is any, and when carrying or take care of, how long blade all can be coiled and be placed in box, extremely convenient; The blade of flexible any radian is adopted to make the utility model not only can measurement component internal diameter or external diameter isoline length but also profiled parts arc length can be measured, expand range of application, have simultaneously lightweight, volume is little, easy to operate, low cost and other advantages.In addition, the utility model also has accurate positioning, advantage easy to use.

Below in conjunction with the accompanying drawing in the utility model embodiment, be clearly and completely described the technical scheme in the utility model embodiment, obviously, described embodiment is only the utility model part embodiment, instead of whole embodiments.Based on the embodiment in the utility model, those of ordinary skill in the art are not making the every other embodiment obtained under creative work prerequisite, all belong to the scope of the utility model protection.
Embodiment
With reference to magnetic sheet and chip architecture of the spring shown in flexible vernier caliper and Fig. 2 shown in Fig. 1, the flexible vernier caliper that the present embodiment provides comprises the graduated tape body 1 of band and vernier 2, vernier 2 is sliding to be inserted on tape body 1, one end place of tape body 1 is provided with fixation measuring pawl, vernier 2 is provided with slip measuring claw.Fixation measuring pawl comprises fixation measuring pawl 7 and lower fixation measuring pawl 8, and slip measuring claw comprises slip measuring claw 9 and lower slider measuring claw 10; Upper fixation measuring pawl 7 and upper slip measuring claw 9 are symmetrical mutually, and lower fixation measuring pawl 8 and lower slider measuring claw 10 are symmetrical mutually; Upper fixation measuring pawl 7, on slide on measuring claw 9, lower fixation measuring pawl 8 and lower slider measuring claw 10 and be provided with inside dimension measuring surface 11 and outside dimension measuring surface 12; Spring leaf 3 is provided with between tape body 1 and vernier 2; Vernier 2 is also provided with trip bolt 4; Magnetic sheet 5 is all embedded with in each inside dimension measuring surface 11 or outside dimension measuring surface 12.Wherein, a magnetic pole of each magnetic sheet 5 is all perpendicular to inside dimension measuring surface 11 or the outside dimension measuring surface 12 at this magnetic sheet 5 place.
Slip measuring claw moves together along with vernier 2, vernier 2 is provided with groove, tape body 1 slides in groove, because tape body 1 is thinner, so be provided with spring leaf 3 between tape body 1 and vernier 2, to prevent tape body 1 from rocking in groove, spring leaf 3 also can be replaced by spring, spring leaf 3 one end is fixed on vernier 2, and the other end withstands on tape body 1.In order to adjust the elasticity of spring leaf 3, can arrange trip bolt 4, trip bolt 4 can pass vernier 2 and withstand on tape body 1, and rotational fastener screw 4 can adjust the distance between vernier 2 and tape body 1.Magnetic sheet 5 can make inside dimension measuring surface 11 fit tightly with band measuring workpieces, ensures measuring accuracy.
Preferably, upper fixation measuring pawl 7, upper slip measuring claw 9, lower fixation measuring pawl 8 and lower slider measuring claw 10 are provided with locating piece 6.A surface of locating piece 6 is attached on measuring claw, and another surface relative with the surface being attached to measuring claw and the inside dimension measuring surface of this measuring claw are at same plane.
In the above-described embodiments, tape body 1 with a scale can be the combination of millimeter scale and centimeter scale; Also can be graduated in English.
Time before measuring, taken out by the utility model from box, the tape coiled recovers linear state in the effect of its own resilient, is wiped clean by each measuring claw, fixation measuring pawl and slip measuring claw are closed up with soft cloth.The position of vernier 2 is adjusted by trip bolt 4.Check whether the zero graduation of vernier 2 and tape body 1 aligns.If alignment just can be measured; If not alignment, then will keep zero error in mind, vernier zero graduation line is positive zero error on the right side of tape body zero graduation line, and vernier zero graduation line is negative zero error on the left of tape body zero graduation line, just can measure after keeping zero error in mind.
When measuring profiled parts arc length, fixation measuring pawl and slip measuring claw are stuck in cambered surface top and the end of profiled parts, tape body bends along extrados, i.e. readable, reading result is: arc length=tape body integral part+vernier fraction part-zero error.Average several times if need to measure, do not need all to deduct zero error, as long as deduct zero error from end product at every turn.
The utility model is when the straight length of measurement component internal diameter or external diameter, consistent with the method for operating of existing traditional vernier caliper, therefore omits.
The above; be only embodiment of the present utility model; but protection domain of the present utility model is not limited thereto; anyly be familiar with those skilled in the art in the technical scope that the utility model discloses; change can be expected easily or replace, all should be encompassed within protection domain of the present utility model.Therefore, protection domain of the present utility model should be as the criterion with the protection domain of described claim.
