Abstract
The utility model relates to a measuring tool, and specifically relates to a three-point circle measurement instrument. The three-point circle measurement instrument of the utility model comprises an arc pedestal. Two fulcrum pins are fixedly installed on the arc pedestal. The arc pedestal is in fixed connection with an instrument seat through a linking arm. A displacement measurement instrument is installed on the instrument seat. A measurement end of the displacement measurement instrument is opposite to fulcrum ends of the fulcrum pins, and is positioned at a same circumference which is adaptable to the diameter of a to-be-measured workpiece. The three-point circle measurement instrument of the utility model is advantageous in that: the three-point circle measurement instrument of the utility model utilizes the principle that three points which are not in a same linear line determine one circle, and the diameter of the to-be-measured workpiece is measured through three points composed of the two fulcrum pins and the measurement instrument; the three-point circle measurement instrument is simple in structure, convenient to use, and high in detection precision; and the three-point circle measurement instrument can carry out on-line detection in a vehicle processing process, so that the detection efficiency is raised.
Description
Technical field
The utility model relates to a kind of measurer, specifically surveys the circle instrument at a kind of 3.
Background technology
In the Vehicle Processing of various products, if the outline of workpiece is the object that decile or similar decile protrude several positions, and will machine projection place circumference the time, due to the projection circumference of complete not, thereby utilize conventional measurer can't directly carry out diameter measurement, usually workpiece need to be taken off to the machine adopted special measuring tool and be measured, affect working (machining) efficiency.
Summary of the invention
Technical problem to be solved in the utility model is, a kind of diameter that can the imperfect circumference workpiece of direct-detection is provided, and can in the Vehicle Processing process, detect online, detection efficiency is high 3 survey the circle instrument.
3 survey circle instrument of the present utility model include arc-shaped base, and two hard-wired fulcrum pins are arranged on arc-shaped base; Arc-shaped base is fixedly connected with a meter base by one section linking arm, and the displacement measurement table is installed on 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 adapted with the workpiece for measurement diameter.
The housing of described displacement measurement table is arranged in a radiai adjustment hole of meter base, and can move and regulate and locate along adjustment hole.
Described displacement measurement table is dial gauge.
The utility model has the advantages that: utilized the not principle of the definite circle of 3 on same straight line, 3 sizes that detect the measured object diameter that form by two fulcrum pins and measurement instrument, simple in structure, easy to use, accuracy of detection is high, can in the Vehicle Processing process, detect online, improve detection efficiency.
The accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
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 arc-shaped base 1; Arc-shaped base is fixedly connected with a meter base 3 by one section linking arm, and displacement measurement table 4 is installed on 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 adapted with the workpiece for measurement diameter.
The housing of described displacement measurement table 4 is arranged in a radiai adjustment hole 5 of meter base, and can move and regulate and locate along adjustment hole.
Described displacement measurement table 4 is dial gauges.
As shown in the figure, the utility model is first zero to the dial gauge school with standard workpiece before the diameter that detects measured object 6, and then the workpiece in processing is detected.
