Abstract
The utility model discloses an internal diameter measuring tool for a small-caliber cylinder, which is mainly used for measuring the caliber of a compressor cylinder. The tool comprising a long rod is characterized in that one end of the long rod is provided with an inside micrometer and the other end of the long rod is provided with an adjusting hand wheel. Both the inside micrometer and the adjusting hand wheel are wound with rope yarns and are connected with each other through the rope yarns. According to the technical scheme of the utility model, the internal diameter measuring tool has the advantages of simple structure, easy fabrication, light weight and convenient operation, and the length of the tool can be adjusted according to requirements. The scales of the inside micrometer can be adjusted through the rotation of the adjusting hand wheel, so that the aim of measurement can be realized.
Description
Technical field
The utility model is mainly used in the measurement of compressor cylinder bore, and small-bore cylinder described in the utility model refers to that cylinder bore is less than or equal to 500mm.
Background technology
When at the scene compressor cylinder being installed, can running into the minor diameter cylinder and need to measure inside diameter.At present adopting micrometer inside caliper, micrometer inside caliper during the MEASUREMENT OF STEAM cylinder bore is to realize extending and shortening the purpose that reaches measurement by adjusting conveyor screw, because the bore of minor diameter cylinder is little, hand is stretched not the interior or arm of suction casig and fallen short of and cause and can't measure.
Summary of the invention
In order to address the above problem, the utility model provides a kind of small-bore cylinder bore survey instrument.
The technical solution of the utility model is: comprise a stock, an end of stock is provided with micrometer inside caliper, and the other end of stock is provided with control hand wheel, twines cotton rope on micrometer inside caliper and the control hand wheel, and micrometer inside caliper is connected cotton rope with control hand wheel and connects.
The utility model is simple in structure, and is easy to process, lightweight, convenient operation, and length can be regulated as required.
The utility model rotates to adjust the scale of micrometer inside caliper by control hand wheel, and to reach the purpose of measurement, through repeatedly on probation, it is convenient, economical and practical to measure.

Among the figure, 1, stock, 2, handwheel, 3, cotton rope, 4, micrometer inside caliper, 5, clamping plate, 6, threaded rod, 7, bolt, 8, setting nut, 9, set nut, 10, wire, 11, electric battery, 12, earphone, 13, support, 14, steel wire, 15, the line pendant, 16, cylinder block.
Embodiment
Embodiment: Fig. 1, Fig. 2, Fig. 3, shown in Figure 4, present embodiment comprises a stock 1, and an end of stock 1 is provided with micrometer inside caliper 4, and the other end of stock 1 is provided with control hand wheel 2, twine cotton rope 3 on micrometer inside caliper 4 and the control hand wheel 2, micrometer inside caliper 4 is connected with control hand wheel by cotton rope 3 connections.
Micrometer inside caliper 4 is fixing with stock 1 by clamping plate 5 and bolt 7.Control hand wheel 2 is by threaded rod, and 6 are connected with stock 1.
In order to increase resistance, cotton rope 3 will be around two circles on micrometer inside caliper and handwheel.
Described cotton rope 3 is that two the end of a thread are joined together to form an O shape.
Shown in Figure 5, the clamping plate 5 of present embodiment and bolt 7 are used for fixed inner diameter milscale 4, also can realize the adjusting of micrometer inside caliper 4 and stock 1 relative position.
The using method of present embodiment is: steel wire is arranged on the support 13 on both sides and by the line pendant 15 at two ends and tightens, and makes steel wire 14 overlap in alignment with the cylinder axial line.
Setting nut 8, set nut 9, threaded rod 6 is used for adjusting the height of control hand wheel 2, makes the rotating part of micrometer inside caliper 4 and handwheel 2 on parallel lines, and namely rope yarn 3 is parallel with steel wire 14;
When micrometer inside caliper 4 contacts cylinder block 16 and steel wire 14 simultaneously, circuit turn-on, people will hear sound on 12 li on earphone, at once micrometer inside caliper 4 are taken out, multiply by 2 at micrometer inside caliper 4 countings is exactly cylinder bore.
