Abstract
The utility model relates to a special precise measuring instrument for internal and external rabbets. The diameters of the internal and external rabbets are measured by an internal diameter dial indicator and an external diameter micrometer in the traditional way. In spite of multiple species and specifications of the internal diameter dial indicators and external diameter micrometers, the measuring range of a single internal diameter dial indicator or external diameter micrometer is limited. The special precise measuring instrument for internal and external rabbets comprises a measuring rail (5) with a sliding chute, wherein the front end of the measuring rail is provided with a supporting block (3); the measuring rail is connected with a sliding block (7); the lower part of the supporting block is connected with a supporting block probe (1) through a nut (2); a lever (9) is fixed to the inside of the sliding block; the lower part of the lever is connected with a sliding block probe (12) through a nut (11); and the upper part of the sliding block is connected with a dial indicator or micrometer (8). The utility model is used for measuring the dimensions of the internal and external rabbets on a furnace motor shell.
Description
Technical field:
the utility model relates to a kind of novel measurement mechanism, is specifically related to the special-purpose precision measuring instrument of a kind of internal and external stopper.
Background technology:
Most dial bore gage and the outside micrometers of adopting of the measurement of
traditional internal and external stopper diameter; Dial bore gage and outside micrometer description are many; But the measurement range of single dial bore gage or outside micrometer is limited; Dial bore gage commonly used and outside micrometer specification and precision are as follows: with the dial bore gage is example, and range is respectively Φ 10-18mm, Φ 18-35, Φ 35-50, Φ 50-100, Φ 50-160, Φ 100-160, Φ 160-250, Φ 20-200, Φ 250-450; Scale division value correspondence respectively is 0.01mm.With the outside micrometer is example, and range is respectively Φ 0-25mm, Φ 25-50mm, Φ 50-75mm, Φ 75-100mm, Φ 100-125mm, is the unit multiplication with 25mm; Scale division value correspondence respectively is 0.001mm.Can find out that from above example it is 200mm that the maximum of dial bore gage is measured range, and the range of outside micrometer is 25mm, exceeds the value of measuring in the range ability and then can't realize measuring.
Summary of the invention:
It is high that the purpose of
the utility model provides a kind of measuring accuracy, easy to operate, the special-purpose precision measuring instrument of the internal and external stopper that the measurement size scope is wide.
Above-mentioned purpose realizes through following technical scheme:
The special-purpose precision measuring instrument of
a kind of internal and external stopper; Its composition comprises: have the measurement rail of chute, described measurement rail front end is equipped with back-up block, and described measurement rail connects slide block; Described back-up block bottom connects the back-up block probe; Lever is equipped with in described slide block inside, and said lever bottom connects the slide block probe, and described slide block top connects dial gauge or clock gauge.
The special-purpose precision measuring instrument of
described internal and external stopper, described back-up block is through the described back-up block probe of nut lock, and described lever is through the described slide block probe of nut lock.
The special-purpose precision measuring instrument of
described internal and external stopper is equipped with lever in the described slide block, and described lever is fixed through jackscrew between described measurement rail and the described slide block through the described slide block of screw lock.
Beneficial effect:
1. the utility model combine the measuring principle and the precision of dial gauge gauge outfit or clock gauge gauge outfit self, can come to measure respectively inner stopper size or male half coupling size according to gauge outfit fixed position difference.
the utlity model has the measuring accuracy height, and are easy to operate, the characteristics that the measurement size scope is wide.
but the single measuring instrument measurement size of the utility model scope is 10-500mm, if accessory size surpasses 500mm, can be with two measuring instruments butt joints, its measurement range is also corresponding to be multiplied.
the utility model has realized utilizing same measuring instrument can measure the internal and external stopper diameter dimension respectively, increases greatly simultaneously and measures range.
the utility model can not only be realized the measurement of inner stopper or male half coupling diameter through the installation site of adjustment percentage gauge outfit; Also the measurement range ability with traditional dial bore gage or external measuring instrument strengthens; Can not only measure 0-Φ 500 range of size; Can also the sleeve pipe of two dial gauges be connected together use, the measurement range of whole measuring instrument is 0-Φ 1000, has so just strengthened the usable range and the use occasion of dial bore gage greatly.
The measuring accuracy of
the utility model can be that percentage gauge outfit or clock gauge head are adjusted according to what use, and is easy to use, of many uses.
The gauge head of
the utility model adopts Φ 4 hard alloy bars, and metal bar two grinds tapering and wedge angle, can contact the surface of inner stopper or male half coupling easily, finds accurate measurement point; Simultaneously; Hard alloy bar is welded to stretching out on the screw rod of measuring instrument, and is respectively fixed on back-up block and the lever with nut, and its length can conveniently be adjusted; It is big that this has just guaranteed that this measuring instrument can not only be measured the diameter range of seam, and the also corresponding increase of the seam depth range that can survey.
