The utility model discloses a kind of inner diameter measuring device, it is characterized in that: it comprises steady arm, is respectively arranged with place kick and reference column at the steady arm two ends, and the steady arm perpendicular bisector is provided with measuring staff, is provided with meter in elongated measuring staff end.The utility model is owing to adopt steady arm and structures such as place kick and reference column, make the utility model can pass through automatic positioning equipment, finding greatest measurement fast is workpiece diameter, make measuring staff can be automatically in measurement, accurately and fast measure the super large workpiece diameter.
Description
Technical field
The utility model relates to a kind of measurement mechanism, relates to a kind of high precision specifically, measures the big workpiece diameter inner diameter measuring device of (comprising bearing, endoporus etc.) fast.
Background technology
At present, at industrial circle, super-large-inside-diameter measurement mechanism more than 1 meter especially for the ordinary surveying device of production scene, has demand and application widely in modern process industry.The main method of measuring the super large workpiece diameter at present has: arc-length methods, roller method and measuring staff method.All by measuring the part arc length or the circumference of internal diameter, indirect calculation goes out tested internal diameter for arc-length methods and roller method, and they all need expensive measuring equipment, and the measuring method complexity is difficult to apply in the production scene; The measuring staff method is utilized elongated measuring staff, by finding out greatest measurement (tested internal diameter), directly measures tested internal diameter, and measurement mechanism is with low cost, and measuring method is simple, is widely used in the production scene.But the measuring staff method needs artificial placement repeatedly, adjusts measuring staff, to find greatest measurement.So measuring process is time-consuming, effort, it is bigger that measurement result is influenced by human factor, had a strong impact on efficiency of measurement and measuring accuracy.
Summary of the invention
It is a kind of based on the measuring staff method that the purpose of this utility model just is to provide, and can pass through automatic positioning equipment again simultaneously, finds the inner diameter measuring device of greatest measurement fast.
The purpose of this utility model can realize by following measure:
The utility model comprises steady arm, is respectively arranged with place kick and reference column at the steady arm two ends, and the steady arm perpendicular bisector is provided with elongated measuring staff, is provided with meter in elongated measuring staff end.
Measuring staff in the utility model is to be placed in to survey in the ball cover tube.Measuring ball is to be placed in the survey table sleeve.Elongated measuring staff can slide on steady arm, by surveying the ball cover tube and surveying the table sleeve, can connect the elongated measuring staff of different length.Meter is a clock gauge, also can adopt other suitable meters certainly.Between elongated measuring staff and the steady arm for being slidingly connected.Reference column is perpendicular to the plane of place kick and measuring staff formation.
The utility model is owing to adopt steady arm and structures such as place kick and reference column, make the utility model can pass through automatic positioning equipment, finding greatest measurement fast is workpiece diameter, make measuring staff can be automatically in measurement, accurately and fast measure the super large workpiece diameter.

Embodiment
The utility model is done with detailed description below in conjunction with drawings and Examples:
As shown in the figure, the utility model comprises steady arm 1, is respectively arranged with place kick 2 and reference column 3 at steady arm 1 two ends, and steady arm 1 perpendicular bisector is provided with elongated measuring staff 4, is provided with meter 5 in elongated measuring staff 4 ends.Elongated measuring staff 4 is to be placed in to survey in the ball cover tube 6.Measuring ball is to be placed in the survey table sleeve 6.Meter 5 is a clock gauge, also can adopt other suitable meters certainly.Between elongated measuring staff 4 and the steady arm 1 for being slidingly connected.The plane that reference column 3 forms perpendicular to place kick 2 and measuring staff 4.In addition, also be provided with sliding sleeve 7 between elongated measuring staff 4 and the steady arm 1 and survey ball cover tube 10, the bottom of elongated measuring staff 4 is provided with surveys ball 8.
Principle of work of the present utility model is as follows: the utility model super-large-inside-diameter measurement mechanism is made up of measuring staff and steady arm two large divisions.Measuring staff is used to measure internal diameter, and steady arm is used to guarantee that measuring staff measures along diametric(al) accurately.The geometrical property of steady arm utilization circle is positioned at measuring staff automatically on measured workpiece 9 internal diameters, thereby does not need artificial searching greatest measurement repeatedly, directly measures tested internal diameter fast.Specific as follows: as shown in drawings, measuring staff is on the perpendicular bisector of steady arm.On the measured circle plane, when placing steady arm on the measured circle, according to the geometrical property of circle, its perpendicular bisector must be tested diameter of a circle; Simultaneously, contact with the tight of measured circle inside surface, measuring staff is on the measured circle plane all the time, owing to measuring staff overlaps with the steady arm perpendicular bisector, so measuring staff must be on the tested diameter of a circle automatically by reference column.Its measurement result is tested internal diameter.So, utilize steady arm to locate automatically, measuring staff can disposablely be accurately positioned on the tested internal diameter, need not to adjust repeatedly measuring staff, can measure tested internal diameter rapidly.Utilize the super-large-inside-diameter measurement mechanism, only need measurement mechanism is placed directly on the measured workpiece, make place kick, reference column and survey ball well to contact,, can measure workpiece diameter fast and accurately by the clock gauge reading on the measuring staff with inside diameter surface.Accompanying drawing is an example structure figure of the present utility model.Further specify principle of work of the present utility model below in conjunction with accompanying drawing: as shown in drawings, the super-large-inside-diameter measurement mechanism is made up of elongated measuring staff, steady arm, sliding sleeve, place kick, sliding sleeve, survey ball, reference column, survey ball cover tube, survey table sleeve, ten major parts of clock gauge.Elongated measuring staff is connected with the survey ball by surveying the ball cover tube, is connected with clock gauge by surveying the table sleeve, forms measuring staff, measures internal diameter size.Elongated measuring staff length can change, to measure the internal diameter of different size.The steady arm left end is place kick, and right-hand member is a positioning cylinder, to guarantee that measuring staff all is positioned on the tested internal diameter with vertical both direction in level.Survey between ball cover tube and the sliding sleeve and can well slide, to guarantee that under the different inner diameters situation surveying ball can both well contact with tested internal diameter.
When measuring internal diameter,, select the elongated measuring staff of respective length at first according to internal diameter theoretical size size, survey ball cover tube and survey table sleeve are installed respectively at two ends, and by robot scaling equipment, verification measuring staff length makes that the measuring staff length when the clock gauge reading is zero is the internal diameter theoretical size.To survey the ball cover jacket casing and go in the sliding sleeve, and measurement mechanism will be placed directly on the measured workpiece again, and make place kick, reference column and survey ball well to contact with inside diameter surface, the clock gauge reading is the actual error value of tested internal diameter.
