Abstract
The invention relates to a large-size inner diameter measurement auxiliary tool which comprises a triangular support arranged in even included-angle distribution mode. The bottom end of a cylindrical sleeve is vertically and fixedly installed at the central position of the triangular support. A T-shaped rocking bar with hollow upper end is arranged on the cylindrical sleeve, the bottom end of the T-shaped rocking bar is vertically sleeved in the cylindrical sleeve, and a measuring rod and a measuring meter are arranged on the T-shaped rocking bar, wherein the measuring rod is arranged in a hollow tube of the T-shaped rocking bar. Fixing devices are respectively arranged at the end-point positions of three branches of the triangular support. The large-size inner diameter measurement auxiliary tool can rapidly find the inner diameter circle center and perform positioning through the triangular support, and can enable the measuring rod to rapidly find a maximum measured value, namely the workpiece inner diameter and enable the measuring rod to accurately measure the inner diameter of an oversized workpiece in the measurement process.
Description
Technical field
The present invention relates to survey instrument, more particularly, relate to a kind of aid for the large scale inner diameter measurement.
Background technology
At present, in the industrial processes field, when measuring super-large-inside-diameter, be difficult to the positioning workpieces internal diameter center of circle exactly, in measuring process, easily make gauge rod that deviation up and down occurs, need duplicate measurements repeatedly, can't measure rapidly and accurately the workpiece diameter size.
Summary of the invention
In view of the foregoing defects the prior art has, technical matters to be solved by this invention is to provide a kind of large scale inner diameter measurement aid, and it can fast and easy and accurately measures the internal diameter size of workpiece.
The technical scheme that the present invention solves the problems of the technologies described above is as follows:
A kind of large scale inner diameter measurement aid comprises support, and described support is provided with sleeve, is set with rocking bar on sleeve, is provided with on described rocking bar for sounding rod and the meter measured.
Beneficial effect of the present invention is: simple and reasonable, easy to use and reliable, can measure quickly and accurately the internal diameter size of workpiece.
Further, described support is the triangular supports that even angle distributes and arranges, and the end points place of three branches of described triangular supports is provided with respectively stationary installation.
Adopt the beneficial effect of above-mentioned further scheme to be, can find rapidly the internal diameter center of circle and accurately locate by triangular supports.
Further, described stationary installation is bolt and be connected the screw of supporting connection.
Adopt the beneficial effect of above-mentioned further scheme to be, fixed, reduce error, make measurement more accurate.
Further, described sleeve is cylindrical sleeve, and the cylindrical sleeve bottom is fixedly mounted on the center of triangular supports vertically.
Adopt the beneficial effect of above-mentioned further scheme to be, guarantee verticality, the degree of stability of single unit system.
Further, described rocking bar is the T-shaped rocking bar of upper end hollow, and the bottom of T-shaped rocking bar vertically is sleeved in cylindrical sleeve, and described sounding rod is placed in the hollow tube of T-shaped rocking bar.
Further, the centre of described bolt is provided with the tapped through hole of M8.
Description of drawings
Fig. 1 is the described large scale inner diameter measurement of embodiment of the present invention aid structural representation;
In accompanying drawing, the list of parts of each label representative is as follows:
1, triangular supports, 2, cylindrical sleeve, 3, T-shaped rocking bar, 4, bolt, 5, screw.
Embodiment
Below in conjunction with accompanying drawing, principle of the present invention and feature are described in detail, example only is used for explaining the present invention, is not be used to limiting scope of the present invention.
As shown in Figure 1, the described large scale inner diameter measurement of preferred embodiment of the present invention aid, comprise the triangular supports 1 that even angle distributes and arranges, described sleeve is cylindrical sleeve 2, and cylindrical sleeve 2 bottoms are fixedly mounted on the center of triangular supports 1 vertically.What is called vertically refers to, the rounded bottom surface of cylindrical sleeve is connected with the center interference fit of triangular supports.Interference fit is used for being fastenedly connected between hole, axle, does not allow to have relative motion between the two.Cylindrical sleeve 2 is provided with the T-shaped rocking bar 3 of upper end hollow, and the bottom of T-shaped rocking bar 3 vertically is sleeved in cylindrical sleeve 2, is provided with sounding rod and meter on described T-shaped rocking bar 3, and described sounding rod is placed in the hollow tube of T-shaped rocking bar 3.The end points place of three branches of described triangular supports 1 is provided with respectively stationary installation, and described stationary installation is bolt 4 and be connected the screw 5 of supporting connection.
The centre of described bolt 4 is provided with the tapped through hole of M8, and the effect of M8 is to form pairing with top screw 5, makes screw 5 and bolt 4 form the mechanism that a up and down can be regulated and can lock.
During concrete the use, triangular supports 1 is placed on the section of workpiece diameter, guarantee triangular supports 1 and workpiece cross section perpendicular, and fixed after using bolt 4 and screw 5 structural adjustments, the T-shaped rocking bar 3 that gauge rod is housed is put into cylindrical sleeve 2, sounding rod two ends and measured circle inside surface close contact, make sounding rod be in all the time on the measured circle plane, slowly rotate T-shaped rocking bar 3, make clock gauge on sounding rod can demonstrate exactly the size of endoporus each point, accurately measure workpiece diameter.The sounding rod size can change, and to measure the different size internal diameter, uses this auxiliary work-piece to make measuring workpieces large diameter size become especially convenient, accurate.
The above is only preferred embodiment of the present invention, is not for limiting the present invention, and is within the spirit and principles in the present invention all, any modification of doing, is equal to replacement, improvement etc., within all should being included in protection scope of the present invention.
