Abstract
A device for detecting precision of tiny and complicated components includes an optical projector and a projection screen, wherein the projection screen is a transparent film movably arranged on the projector; mark contour lines for marking the upper limit size and the lower limit size of precision of a workpiece are arranged on the transparent film; and the sizes of the mark contour lines on the transparent film are consistent with the magnification ratio of the optical projector. A detection method for detecting the precision of tiny and complicated components includes the following steps: firstly, projection; secondly, transparent film adjustment; and thirdly, contrast detection. Through the adoption of the device and the method provided by the invention, the precision of components can be directly confirmed in a contrast manner without measuring sizes of components, the operation is convenient, the working efficiency can be improved for more than ten times, and the method and the device are particularly suitable for batch detection of tiny components.
Description
Technical field
The present invention relates to a kind of pick-up unit and detection method of parts degree of accuracy, especially a kind of device and detection method that detects the degree of accuracy of small, complicated, precision parts.
Background technology
Existing technology is to adopt optical measuring method to the method for inspection of the degree of accuracy of small, accurate parts; Through confirming of survey data according to next; Yet it is minimum for some sizes; As about size 1mm; Profile has that characteristics such as circular arc, angle, straight line intersect and the complex parts of dimension precision requirement ± 0.005mm, and conventional optical measurement often can't be measured the part accurate size owing to can't accurately catch geometric properties such as focus, causes judging whether part reaches desired precision.
Summary of the invention
The problem that the present invention will solve is to provide a kind of device that detects small complex parts degree of accuracy, and this device can ensure the accuracy of detection, can improve detection efficiency again.
The present invention adopts following technical scheme: comprise optical projector and projection screen; Optical projector is provided with the work piece platform that is used to put parts; Said projection screen is the movable transparent film that is arranged on the projector; Said transparent film is provided with the sign outline line of workpiece accuracy bound size, and the enlargement factor of size and the optical projector of sign outline line on transparent film is consistent.Its principle is: small parts are shown on the transparent film after amplifying through optical projector; Transparent film is provided with the workpiece accuracy bound size sign outline line of same enlargement factor; With the projected outline of parts and the contrast of the sign outline line on the transparent film; If the projected outline of parts shows that then the dimensional accuracy of small parts meets the requirements between the bound size of sign outline line; Otherwise, then do not conform to the symbol requirement.
Another object of the present invention is to provide a kind of detection method of small complex parts degree of accuracy.
A kind of detection method of small complex parts degree of accuracy comprises the steps:
(1) projection operation: small parts are placed on the work piece platform of optical projector, start projector, project on the transparent film after the profile of small parts promptly is exaggerated;
(2) adjustment transparent film: the fixed position of adjustment transparent film is overlapped on the sign outline line projected outline of small parts;
(3) comparison and detection: with the projected outline of small parts and the contrast of the sign outline line on the transparent film, if the projected outline of small parts shows that then the dimensional accuracy of small parts meets the requirements between the bound size of sign outline line; Otherwise, then do not conform to the symbol requirement.
Adopt the present invention; Can be directly sign outline line through the part bound size on part projected outline and the transparent film contrast, confirm the precision of part, and the accurate dimension data that need not measure parts are confirmed its precision; Therefore can disposable completion to the detection of small complex parts accuracy to size; It is easy to operate, and work efficiency can improve tens of times, is particularly useful for the batch check of small parts.
