Technical field

The present invention relates to dimensional measuring instruments, more particularly to a kind of for measuring the spacing of the opposite face of two objects Measuring device.

Background technique

Common measuring tool such as ruler, angle square, micrometer, vernier caliper etc., their application range and use condition It has nothing in common with each other, and different types of measurement needs can be met respectively.But for some particular surroundings, existing measuring tool is still It is difficult to needed for effectively meeting, such as in the installation construction of Nuclear island equipment, needs at the stage of debugging to nuclear island steam generation Horizontal supporting gap between the upper and lower part of device measures, but since the volume of steam generator is big, gap is small and measures Point quantity is more, and the extreme temperatures of place environment, causes measurement to be difficult to effectively carry out, existing measuring tool is also difficult to meet survey Needed for amount.

Summary of the invention

It is simple the purpose of the present invention is to provide a kind of structure and between capable of easily and quickly measuring between two opposite faces Away from measuring device, with improve measurement working efficiency and accuracy.

Gap measuring device of the present invention, including the clamping being dismantledly fixed on one of object under test Block, and clamping block is equipped with the datum level that is in contact with the face to be measured of the object under test, be also provided on clamping block measured hole and The axis of locating slot, measured hole is vertical with datum level, and locating slot is along another plane setting for being parallel to datum level, and measured hole is worn Cross locating slot；Separately there are partition and the dial gauge for survey measurements, partition can be placed in the locating slot of clamping block simultaneously with picking and placing Measured hole can be blocked, the gauge rod of dial gauge passes through measured hole and the gauge head of gauge rod end and the surface of another object under test offset.

Gap measuring device of the present invention, dial gauge are to utilize the general length of tabular form made of accurate rack and pinion mechanism Measuring tool is spent, is made of gauge head, gauge rod, antirattle spring, rack gear, gear, balance spring, round dial and pointer etc.；By clamping After block is fixed on one of object under test, the face to be measured of datum level and the object under test on clamping block, i.e., two One of opposite face of object is in contact；Then the gauge rod of partition and dial gauge is successively put into locating slot and the survey of clamping block In metering-orifice；At this point, measured hole is obstructed at locating slot by partition, the gauge head of dial gauge gauge rod end offsets with partition, by this Dial gauge under state is adjusted to zero graduation；Then, partition is withdrawn from locating slot, dial gauge gauge rod passes through clamping block Measured hole and offset with the surface of another object under test, dial gauge would indicate that reading；After recording the reading, i.e., visual benchmark Reading is carried out plus-minus calculating with set distance, to obtain two object under test phases by the set distance between face and locating slot Spacing between opposite.The structure of the gap measuring device is extremely simple, can meet the use needs of various varying environments, fits It is extremely wide with range；Meanwhile the device is easy to operate, and extremely can quickly and accurately measure two object under test opposite faces Between spacing, to effectively improve the working efficiency and accuracy of measurement.

Specific embodiment

A kind of gap measuring device, including the clamping block 1 being dismantledly fixed on one of object under test, and clamping Block is equipped with the datum level 2 being in contact with the face to be measured of the object under test, is also provided with measured hole 3 and locating slot 4 on clamping block, The axis of measured hole is vertical with datum level, and locating slot is along another plane setting for being parallel to datum level, and measured hole passes through positioning Slot；Separately there are partition 5 and the dial gauge 6 for survey measurements, partition can be placed in the locating slot of clamping block and can hide with picking and placing Measured hole is kept off, the gauge rod 7 of dial gauge passes through measured hole and the gauge head of gauge rod end and the surface of another object under test offset.

The gap measuring device is provided on clamping block 1 towards the side of one of object under test and to be recessed inwardly Card slot 8, and a wherein face side wall for card slot is benchmark face 2；Locking screw holes 9 are also provided on clamping block, the end of locking screw holes is set The tie down screw 10 in card slot on another side wall, being spirally connected with locking screw holes is placed in pass through locking screw holes and offset with object under test, To which clamping block is fixed on object under test.In addition, being also provided on clamping block 1 for hand-held handle 11, with convenient Personnel operate.

As shown in Figure 1, 2, plan clamping block to be fixed on one of object under test, card slot is towards another object under test Side is datum level；In addition, the locating slot on clamping block is set between clamping block datum level and another object under test, so that There are a set distance value a between datum level and locating slot.

When measuring, after clamping block is fixed on one of object under test, datum level on clamping block with One of opposite face in the face to be measured of the object under test, i.e., two objects is in contact；Then successively by partition and dial gauge Gauge rod be put into the locating slot and measured hole of clamping block；At this point, measured hole is obstructed at locating slot by partition, dial gauge amount The gauge head of bar end offsets with partition, and the dial gauge under the state is adjusted to zero graduation；Then, partition is removed from locating slot It walks, dial gauge gauge rod passes through the measured hole of clamping block and offsets with the surface of another object under test, and dial gauge would indicate that reading Number b.Spacing between so two objects under test is are as follows: L=a+b.

Similarly, if plane where locating slot is set to datum level, then: L=b；If locating slot is set to datum level Except the one side of another object under test, then: L=b-a.In addition, several locating slots 4 can be set on clamping block 1, To improve the scope of application of gap measuring device, meet the requirement of varying environment.

The structure of the gap measuring device is extremely simple, can meet the use needs of various varying environments, the scope of application It is extremely wide；Meanwhile the device is easy to operate, and extremely can quickly and accurately measure between two object under test opposite faces Spacing, to effectively improve the working efficiency and accuracy of measurement.
