A level gauge comprising a frame body, a rod with a disk, a reading unit and a level is provided with a bracket mounted on the disk with a reference plane interacting with the reading unit, a rod mounted in the slot of the rod that can be moved perpendicular to its axis, as well as an additional rod installed in slots that are made in the tops of the rectangular frame of the housing. The rod is made with the possibility of rotation around its axis, the disk is around the axis of the rod, and the level and the reference node are installed on the rod. 1 hp f-ly, 5 ill.

Description

The invention relates to a measurement technique, namely, devices for monitoring and measuring the straightness, parallelism and perpendicularity of remote surfaces and rods of multi-rod trusses, in particular frames, cases and systems, and their complex machine systems.

The purpose of the invention is to improve the accuracy and productivity of measuring the linear deviations of the relative position of structural elements.

FIG. 1 shows a frame level gauge, a general view; in fig. 2 is a schematic diagram of the control of the transfer of the uprights of the tested structure with respect to the horizontal beam; in fig. 3 - level gauge application

with additional rods; in fig. four

the use of the gauge as a micron level; in fig. 5 - specific design of the mechanisms of rotation of the disk and rod.

The gauge comprises a housing made in the form of a rectangular frame 1 with working surfaces 2 along its faces, a rod 3 mounted on a frame 1 in a plane parallel to the planes of its faces with the possibility of rotation around its axis, a disk 4 mounted on a rod 3 with the possibility of rotation and fixation around its axis, level 5 and the reference node 6. The level gauge is also provided with a bracket 7 rigidly fixed to the disk 4 with a support platform 8 located in the same plane with the axis of the rod 3, designed to interact with the measuring tip 9 nickname otschet- Nogo assembly 6 mounted in the groove of the rod 3 is movably and fixing its axis perpendicular to the rod 10 with 1L schkaloy level 5 and the reference

node 6 is mounted on this rod 10.dikurnost between elements in mm on In frame 1 at the vertices of the rectangular base length of the retractable rod 10. When the grooves 12 are made, it is intended to simplify the recalculation of the deviation of the 13 additional rods in them the length of the element of the structure is height-adjustable lugs 14. The potion by stirring the rod 10 in the slot of the gate of the disk 4 around the axis of the rod 3 wasp shaft 3 sets the rod to the height by means of the mechanism 15, the measuring state (on the bar scale) , multiple to the length of this worm 1 6, of the installed controllable element (according to the scale of the frame 1 and the worm gear 17, set-measurement). Since the principle of the disk 4. The rotation of the device 3, when measuring the actual dryness around its axis, determined the mechanism of the 10 deviations of the position controlled by the element 18, consisting of a screw 19, the settings are based on the similarity of a rectangular the wheel 17, and the worm wheel triangle (D ABC is similar to L avs, sa 20, mounted on the rod 3.fig. 2), then the measurement accuracy is not dependent on the rod 10 fixed in the groove of the rod-sit on the magnitude of the deflection angle, n 3 screw 21.

Claims (1)

Positions of structural elements of the frame formula of the invention The level gauge is placed in a vertical plane on the base section of one of the contro-25 Frame level gauge containing correlated structural elements (Fig. 2, empty, made in the form of a rectangular position I) as indicated by the transverse am-frame with surfaces in its grapula of level 22. By rotating the screw of the machine, the rod mounted on the frame in the bottom 15 of the movement is disk 4 together with the planes parallel to the planes of its rod 3, barbell 10 with reference nodes facets, the disk mounted on the rod scrap 6 level gauge set to 30 seconds the ability to rotate around its axis, a longitudinal ampoule of level 5 in a polo level and a reference node, which is horizontal, which, in order to increase the accuracy of the plane. Then the gauge of the measurement performance is supplied, it is equipped with a second monitored structural element fixed on the disk with a bracket (the relative position of which is determined) with a supporting platform located, for example, on a vertical stand (mounted on a plane with the axis of the rod). - Understanding II). If the structural elements are perforated in the rod with the possibility of displace- ment of each other, then the position perpendicular to its axis by the rod from the bubble in the longitudinal ampulla of the 5-fold layer, the rod is made possible with the former. Otherwise, by turning the rotation around its axis, and by reducing the screw of the turning mechanism 18, the whole and the measuring unit are installed on the rod 3 together with the fixed bar with the ability to interact with the measuring unit 6 from the measuring tip the reference node on the other side relative to the disk 4 to the support bracket platform, the rotation of the ampoule bubble into the original 2. Level gauge according to claim 1, which has a different position. In this case, the measurement is provided in that it is equipped with an additional pinnacle 9 of the reference node 6, interaction with a height-adjustable stop, and in the backbone platform 8, remaining in the rectangular corner of the stationary bracket 7 the disk 4, the grooves perpendicular to its faces are not, through the measuring transducer, for installation in them, the deviation from the perpendicular rod is recorded on the scale. 15 23 23 18   V 12 12 X Lj // I 2 7 5 11 10 21 J 75-474 P ig. one fie. g 7J //////////. .., xxx Fig.Z t X 73 X / v FIG. four
