Background technology
For the short circular arc that only has 1/5 full circle, the method in the measurement circular arc center of circle of adopting at present has 2 kinds substantially: 1. after adopting three coordinate measuring machine centering workpiece, utilize the survey ball to gather a series of data points on arc surface, then calculate arc diameter and the center of circle by the measuring system of three-dimensional; 2. adopt universal tool-measuring microscope to carry out projection, the centering workpiece coordinate system overlaps with the microscope coordinate system, measures all quadrants coordinate points on arc surface in the coordinate system of tool microscope, then calculates arc diameter by calculating, extrapolates center of arc's coordinate.These two kinds of method measuring processes are complicated, and a skilled detection person needs just can complete in 15 minutes the detection of a product at least, so these two kinds of methods can not satisfy the needs of production scene Quick Measurement in enormous quantities.
Summary of the invention
The purpose of this utility model is to provide a kind of short arc oval arc central distance measurer, and the utility model energy simplified measurement step makes simple to operateization, shortens Measuring Time.
The technical scheme of goal of the invention of the present utility model is as follows:
the oval arc central distance measurer of short arc, the upper surface of base is provided with fixed cover, dial framework and bearing, described fixed cover is provided with axially parallel in the guide rail of base lower surface, a slide block and described guide rail are slidably matched, one end of two connecting rods is along the slide block vertical direction and is movably connected in one on the other on slide block, the other end of two connecting rods is flexibly connected with a sounding rod respectively, the lower surface of sounding rod is V-shaped, described dial framework is provided with the first survey table and the second survey table, the first gauge head of surveying table contacts with the upper surface of described sounding rod, second surveys the gauge head of table and the contacts side surfaces of sounding rod, described bearing is provided with the workpiece positioning element.
The two ends of described guide rail all are connected with the jump ring that guide rail is carried out axial limiting.
Be equipped with the hole on described slide block and sounding rod, the two ends of two connecting rods are inserted in slide block and hole that sounding rod is connected by bearing pin respectively and connect.
Be equipped with lining in hole on described slide block and sounding rod, described bearing pin is inserted in lining.
Described workpiece positioning element is locator mandrel.
Described locator mandrel is the locator mandrel of taper.
Adopted such scheme, when using the utility model that workpiece is detected, first master body is arranged on bearing by the workpiece positioning element, sliding slider and swing sounding rod, make the V-arrangement lower surface of sounding rod accurately contact the exemplar circular arc, adjust the first dial gauge and the second dial gauge total indicator reading, be designated as " 0 " point with reading at this moment.Take out exemplar, measured workpiece is arranged on bearing by the workpiece positioning element, sliding slider and swing sounding rod makes the V-arrangement lower surface of sounding rod accurately contact workpiece circular arc, and the value that this moment, two dial gauges departed from " 0 " point is center of circle position difference in the horizontal and vertical directions.By structure of the present utility model, can detect by simple three operation stepss, product time of average detected is no more than 15 seconds, greatly shortened detection time, under equal measuring accuracy prerequisite, the quick measurement of comparison of energy center of arc distance, and broken away from the limitation of always using three-dimensional and universal tool-measuring microscope to measure, be applicable to the production scene rapid batch and detect.
Below in conjunction with the drawings and specific embodiments, the utility model is further illustrated.
