Abstract
A device for detecting accuracy of a micro complex part comprises an optical projector and a projection screen. The projection screen is a transparent film movably arranged on the transparent film of the projector. The transparent film is provided with a symbol contour which is used for limiting the accuracy upper size and the lower size of a work piece, and the size of the symbol contour on the transparent film is the same as the magnification time of the optical projector. After adopting the device for detecting the accuracy of the micro complex part, the accuracy of the part can be directly compared and determined, the size data of the part are not required to be measured, the operation is convenient, and the working efficiency can be improved by ten times, so that the device is specially suitable for checking the micro parts in batches.
Description
Technical field
The utility model relates to a kind of pick-up unit of parts degree of accuracy, especially a kind of device 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, by determining according to next of survey data, yet minimum for some sizes, as about size 1mm, profile has the complex parts of the Feature interactions such as circular arc, angle, straight line and dimension precision requirement ± 0.005mm, conventional optical measurement often can't be measured the part accurate size owing to can't accurately catch the geometric properties such as focus, causes judging whether part reaches desired precision.
The utility model content
Problem to be solved in the utility model 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 utility model adopts following technical scheme: comprise optical projector and projection screen, optical projector is provided with for the work piece platform of putting parts, described projection screen is the movable transparent film that is arranged on the projector, described transparent film is provided with the sign outline line of workpiece accuracy bound size, and the size of sign outline line on transparent film is consistent with the enlargement factor of optical projector.Its principle is: small parts are shown on the transparent film after amplifying by 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.
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 namely is exaggerated;
(2) adjust transparent film: adjust the fixed position of transparent film, the projected outline of small parts is overlapped on the sign outline line;
(3) contrast detects: 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 utility model, can directly pass through the sign outline line contrast of the part bound size on part projected outline and the transparent film, determine the precision of part, and the accurate dimension data that need not measure parts are determined its precision, therefore can disposablely finish the detection to small complex parts accuracy to size, it is easy to operate, and work efficiency can improve decades of times, is particularly useful for the batch check of small parts.
Description of drawings
Fig. 1 is the structural representation of a kind of embodiment of the utility model.
Fig. 2 is the sign outline line schematic diagram of the parts bound size that shows on the transparent film behind the projective amplification.
Fig. 3 is the results of comparison schematic diagram through the sign outline line of the parts bound size that shows on the spare part profile that amplifies and the transparent film.
Embodiment
As shown in Figure 1 to Figure 3, a kind of embodiment of the utility model comprises optical projector 1 and projection screen 2, optical projector 1 is provided with for the work piece platform 3 of putting parts, described projection screen 2 is movable transparent films 4 that are arranged on the projector 1, described transparent film 4 is provided with the sign outline line 5 of workpiece accuracy bound size, and the size of sign outline line 5 on transparent film 4 is consistent with the enlargement factor of optical projector 1.Its principle is: small parts are shown on the transparent film 4 after amplifying by optical projector 1, transparent film 4 is provided with the workpiece accuracy bound size sign outline line of same enlargement factor, projected outline 6 and 5 contrasts of the sign outline line on the transparent film with parts, if the projected outline of parts 6 shows that then the dimensional accuracy of small parts meets the requirements between the bound size of sign outline line 5; Otherwise, then do not conform to the symbol requirement.
A kind of improvement is that described enlargement factor is 40 times.
The utility model can be done multiple similar variation, and all and the utility model apparatus structure be other equivalent transformation similarly, all falls into protection domain of the present utility model.
Claims (2)
1. device that detects small complex parts degree of accuracy, it is characterized in that: comprise optical projector and projection screen, optical projector is provided with for the work piece platform of putting parts, described projection screen is the movable transparent film that is arranged on the projector, described transparent film is provided with the sign outline line of workpiece accuracy bound size, and the size of sign outline line on transparent film is consistent with the enlargement factor of optical projector.
