Abstract
The invention relates to a measuring tool, and especially relates to a three-point circle-measuring instrument. The three-point circle-measuring instrument of the invention comprises an arc pedestal. Two fulcrum pins are fixedly installed on the arc pedestal. The arc pedestal is fixedly connected to an instrument seat. A displacement measurement table is installed on the instrument seat. A measurement end of the displacement measurement table is opposite to the fulcrum ends of the fulcrum pin and is in a same circumference which is adaptable to a diameter of a to-be measured workpiece. The three-point circle-measuring instrument of the invention is advantageous in that: the principle that three points in different line can determine a circle is utilized; the diameter of the to-be measured workpiece can be measured through three points formed by the two fulcrum pins and the measuring instrument; the three-point circle-measuring instrument of the invention is simple in structure, convenient to use, high in measurement precision; in addition, the three-point circle-measuring instrument of the invention can perform on-line detection in a vehicle processing process, and the detection efficiency is improved.
Description
Technical field
The present invention relates to a kind of measurer, specifically be at a kind of 3 and survey the circle instrument.
Background technology
In the Vehicle Processing of various products, if the outline of workpiece is the object that five equilibrium or similar five equilibrium protrude several positions, and will machine projection place circumference the time, because projection does not constitute complete circumference, thereby utilize conventional measurer can't directly carry out diameter measurement, usually workpiece need be taken off the machine adopted special measuring tool and measure, influence working (machining) efficiency.
Summary of the invention
Technical matters to be solved by this invention is, a kind of diameter that can directly detect imperfect circumference workpiece is provided, and can online detection in the Vehicle Processing process, detection efficiency is high 3 survey the circle instrument.
3 survey circle instrument of the present invention include arc-shaped base, and two hard-wired fulcrum pins are arranged on the arc-shaped base; Arc-shaped base is fixedlyed connected with a meter base by one section linking arm, and the displacement measurement table is installed on the meter base, and the measuring junction of displacement measurement table is relative with the support end of described fulcrum pin and be positioned on the same circumference that adapts with the workpiece for measurement diameter.
The housing of described displacement measurement table is installed in the radiai adjustment hole of meter base, and can move along adjustment hole and regulate and the location.
Described displacement measurement table is dial gauge.
Advantage of the present invention is: utilized the not principle of the definite circle of 3 on same straight line, 3 sizes that detect the measured object diameter by two fulcrum pins and measurement instrument composition, simple in structure, easy to use, accuracy of detection is high, can in the Vehicle Processing process, carry out online detection, improve detection efficiency.
Description of drawings
Fig. 1 is structural representation of the present invention.
Embodiment
As shown in the figure, survey the circle instrument at these 3 and include arc-shaped base 1, two hard-wired fulcrum pins 2 are arranged on the arc-shaped base 1; Arc-shaped base is fixedlyed connected with a meter base 3 by one section linking arm, and displacement measurement table 4 is installed on the meter base, and the measuring junction of displacement measurement table is relative with the support end of described fulcrum pin and be positioned on the same circumference that adapts with the workpiece for measurement diameter.
The housing of described displacement measurement table 4 is installed in the radiai adjustment hole 5 of meter base, and can move along adjustment hole and regulate and the location.
Described displacement measurement table 4 is dial gauges.
As shown in the figure, it is zero to the dial gauge school with standard workpiece earlier that the present invention wanted before the diameter that detects measured object 6, and then the workpiece in the processing is detected.
