Common measuring tools such as straightedges, angle rulers, micrometers, vernier calipers and the like have different application ranges and use conditions and can respectively meet the measuring requirements of different types. However, for some special environments, the existing measuring tool still cannot meet the requirement effectively, for example, in the installation construction of the nuclear island equipment, the horizontal supporting gap between the upper part and the lower part of the nuclear island steam generator needs to be measured in the debugging stage, but the steam generator has large volume, small gap, large number of measuring points and extremely high temperature of the environment, so that the measurement is difficult to be carried out effectively, and the existing measuring tool also cannot meet the requirement of measurement.
Disclosure of Invention
An object of the utility model is to provide a simple structure and can make things convenient for, measure the measuring device of interval between two opposite faces fast to improve measuring work efficiency and accuracy.
The space measuring device of the utility model comprises a clamping block which is detachably fixed on one of the objects to be measured, a datum plane which is contacted with the surface to be measured of the object to be measured is arranged on the clamping block, a measuring hole and a positioning groove are also arranged on the clamping block, the axis of the measuring hole is vertical to the datum plane, the positioning groove is arranged along the other plane which is parallel to the datum plane, and the measuring hole passes through the positioning groove; in addition, the partition plate and the dial indicator for measuring the reading are arranged in the positioning groove of the clamping block in a pick-and-place mode and can shield the measuring hole, and the measuring rod of the dial indicator penetrates through the measuring hole and the measuring head at the tail end of the measuring rod is abutted to the surface of another object to be measured.
The utility model discloses a distance measuring device, the dial indicator is a table type general length measuring tool made of a precise rack and pinion mechanism, and the dial indicator comprises a measuring head, a measuring rod, a shockproof spring, a rack, a gear, a hairspring, a round dial and a pointer; after the clamping block is fixed on one of the objects to be measured, a reference surface on the clamping block is contacted with a surface to be measured of the object to be measured, namely one opposite surface of the two objects; then the clapboard and the measuring rod of the dial indicator are sequentially placed into the positioning groove and the measuring hole of the clamping block; at the moment, the measuring hole is blocked by the partition plate at the positioning groove, the measuring head at the tail end of the measuring rod of the dial indicator is abutted against the partition plate, and the dial indicator in the state is adjusted to be zero scale; then, the partition plate is removed from the positioning groove, the measuring rod of the dial indicator penetrates through the measuring hole of the clamping block and abuts against the surface of another object to be measured, and the dial indicator displays a reading; after recording the reading, the set distance between the reference surface and the positioning groove can be viewed, and the reading and the set distance are added and subtracted to calculate, so that the distance between the opposite surfaces of the two objects to be measured is obtained. The structure of the distance measuring device is very simple, the use requirements of various environments can be met, and the application range is very wide; meanwhile, the device is convenient to operate, and can quickly and accurately measure the distance between the opposite surfaces of the two objects to be measured, so that the working efficiency and the accuracy of measurement are effectively improved.

Detailed Description
A distance measuring device comprises a clamping block 1 which is detachably fixed on one object to be measured, a reference surface 2 which is contacted with a surface to be measured of the object to be measured is arranged on the clamping block, a measuring hole 3 and a positioning groove 4 are also arranged on the clamping block, the axis of the measuring hole is vertical to the reference surface, the positioning groove is arranged along the other plane which is parallel to the reference surface, and the measuring hole penetrates through the positioning groove; in addition, a partition plate 5 and a dial indicator 6 for measuring reading are arranged, the partition plate can be placed in the positioning groove of the clamping block in a pick-and-place mode and can shield the measuring hole, and a measuring rod 7 of the dial indicator penetrates through the measuring hole and a measuring head at the tail end of the measuring rod is abutted to the surface of another object to be measured.
In the distance measuring device, one side of the clamping block 1, which faces one of the objects to be measured, is provided with an inward-concave clamping groove 8, and the side wall of one side of the clamping groove is a reference surface 2; the clamping block is also provided with a locking screw hole 9, the tail end of the locking screw hole is arranged on the other side wall in the clamping groove, and a locking screw rod 10 screwed with the locking screw hole penetrates through the locking screw hole and abuts against an object to be detected, so that the clamping block is fixed on the object to be detected. In addition, a handle 11 for holding by hand can be arranged on the clamping block 1, so that the operation is convenient for a person.
As shown in fig. 1 and 2, a clamping block is to be fixed on one of the objects to be measured, and one side of the clamping groove facing the other object to be measured is a reference surface; in addition, the positioning groove on the clamping block is arranged between the reference surface of the clamping block and another object to be measured, so that a set distance value a exists between the reference surface and the positioning groove.
When in measurement, after the clamping block is fixed on one of the objects to be measured, the reference surface on the clamping block is contacted with the surface to be measured of the object to be measured, namely one opposite surface of the two objects; then the clapboard and the measuring rod of the dial indicator are sequentially placed into the positioning groove and the measuring hole of the clamping block; at the moment, the measuring hole is blocked by the partition plate at the positioning groove, the measuring head at the tail end of the measuring rod of the dial indicator is abutted against the partition plate, and the dial indicator in the state is adjusted to be zero scale; and then, the partition plate is removed from the positioning groove, the measuring rod of the dial indicator penetrates through the measuring hole of the clamping block and abuts against the surface of another object to be measured, and the dial indicator displays a reading b. The distance between the two objects to be measured is then: l = a + b.
