Abstract
The utility model discloses a digital outside and inside diameter measuring instrument, comprising a measuring instrument body which comprises a handle and an instrument panel in connection with the handle; the inner of the instrument panel is provided with two measurement arms engaged with each other; the instrument panel wall between the two measurement arms is connected with a measurement fulcrum. When the digital outside and inside diameter measuring instrument with the above structure is employed to measure outside diameters of cylindrical objects or parts, contact rollers contact with objects to be detected to put forward the measuring instrument body until the measure fulcrum contacts with the workpiece, meanwhile gears drive an angular displacement sensor to generate angular displacement, and finally outside diameter values of the parts are obtained through the treatment of a CPU (Central Processing Unit). While in a process of measuring the inside diameters of the cylindrical objects or parts, the measurement arms are rotated to the back side of the measure fulcrum and the inside diameter values of the parts can be obtained by employing the same principle. The digital outside and inside diameter measuring instrument has a simple structure and is convenient to carry.
Description
Technical field
The utility model relates to a kind of diameter measurement instrument, especially relates to the explicit interior external measuring instrument of a kind of large-scale circular number of components.
Background technology
To the diameter measurement of round member, lack general survey instrument at present, common routine measurement instruments such as vernier caliper often are difficult to satisfy the needs of actual engineering.For example to the diameter measurement of the members such as round steel pipe of the drag-line of the circular pier stud of bridge, Suo Cheng bridge and steel pipe arch bridge; The diameter of member does not often wait between 200cm-4000cm; Even big also can surpassing to some extent, general method commonly used is through ruler manual observation comparison or through tape measure its circular girth is measured, then calculates through formula; The anti-diameter of releasing this member; Such method of testing not only is difficult to guarantee in the actual mechanical process tape measure for the accuracy of circumferential measurements, and inevitably can produce cumulative errors counter pushing away in the computation process, and precision of test result is had very big influence.
The utility model content
The technical matters that the utility model will solve provides a kind of simple in structure, is suitable for measuring external measuring instrument in the digital display type of interior outside diameter measuring of members such as round steel pipe of the circular pier stud of cylinder, bridge and steel pipe arch bridge of heavy construction.
For solving the problems of the technologies described above; External measuring instrument comprises a measuring instrument body in the utility model digital display type; This measuring instrument body comprises handle and the panel board that links to each other with this handle, and two gage beams that are meshed each other are installed in this panel board, the same distolateral equal gear of modulus that is connected with respectively of each gage beam; The other end is respectively equipped with the contact roller, and said two gage beams are meshed through being arranged on same two distolateral gears; On the panel board wall between said two side amount arms, be connected with the measurement fulcrum; Said two gage beams are positioned on the same surface level with this measurement fulcrum, and the measurement fulcrum equates to the distance between the roller center of circle, contact of said another gage beam one end with this measurement fulcrum to the distance between the roller center of circle, contact of said one of them gage beam one end; Said one of them gear is connected with angular displacement sensor; Also be provided with slide block mechanism in the said panel board, it comprises a slide block box, is provided with compression spring in the slide block box, is connected with travelling arm between the compression spring in one of them gage beam and this slide block box; Said handle is provided with display screen and reading button.
The interior external measuring instrument of digital display type that adopts said structure is when using measurement cylindrical object or part external diameter; The contact roller touches measured body; Promote the measuring instrument body forward and touch workpiece until measuring fulcrum; Gear driven angular displacement sensor rotation simultaneously produces angular displacement, obtains the numerical value of diameter of part at last through the processing of CPU.When measuring cylindrical object or part internal diameter, use the internal diameter that same principle just can be measured part when forwarding gage beam to measurement fulcrum rear side.The utility model is simple in structure, and is easy to carry.
