Abstract
The utility model discloses a miniature measuring type optical projector, wherein above a base there are provided a light source and an adjustable work table, a body is provided with a projection screen and an objective lens located on the adjustable work table, inside the body there is provided an amplification projection apparatus, inside the body there is also provided an optical sensing measuring apparatus, and the optical sensing measuring apparatus is connected with a liquid crystal screen. The miniature measuring type optical projector compares the size of a sample gap with a standard size through data, thereby being high in measuring accuracy and more convenient in comparison and having great practicality.
Description
Technical field
The utility model relates to a kind of testing equipment, when relating in particular to a kind of metal material and doing impulse test, and the optical projector of check sample piece V-arrangement and U-shaped notch geometry quality.
Background technology
Along with the development of domestic industry technology, increasing industry has begun to carry out the Charpy V test method.For Charpy V test, whether the v-notch of sample is processed qualified is the key issue of test, if the crudy of sample break is defective, the result of its test is incredible so, the subtle change at R0.25mm breach tip (its tolerance range only has 0.025mm) particularly, the capital causes the steep jumping of test findings, especially can cause product or scraps or qualified two kinds of diametrically opposite results when the critical value of test.More qualified than v-notch for guaranteeing the summer that processes, the crudy check of its breach is an important quality control method.Present small-sized measurement type optical projector can carry out projective amplification with sample break, then compare with standard size, although improved to a certain extent breach quality checking precision, but be difficult to judge notch size and standard-sized actual gap by observing intuitively, therefore still have larger error.
The utility model content
For overcoming above-mentioned technical matters, the utility model provides a kind of reasonable in design, and is easy to operate, the small-sized measurement type optical projector that testing accuracy is high.
For realizing above-mentioned technical purpose, the utility model is realized by the following technical solutions: a kind of small-sized measurement type optical projector, the base top is provided with light source and adjustable bed, body is provided with projection screen and is positioned at the object lens of adjustable bed top, inside is provided with the enlarging projection device, it is characterized in that: be provided with one in the body for the light sensation measurement mechanism of measuring pattern size on the projection screen, the light sensation measurement mechanism is connected with LCDs, LCDs is fixed in body one side.
Its principle of work is: when carrying out the sample inspection, sample is fixed on the adjustable bed, the line position of going forward side by side is regulated, object lens are sent to the projection of sample in the body, amplification through the internal body element is processed, and is projected on the projection screen, can compare notch size and standard size, simultaneously the light sensation measurement mechanism is measured the pattern on the projection screen by light sensitive component, and numerical value is transferred to liquid crystal display shows.
The utlity model has following beneficial effect: it carries out datumization with the projection pattern, and show by LCDs, can detect very intuitively the sample break size, then the standard size with testing requirements compares, can know whether sample is qualified, and it compares by data, and accuracy of detection is high, contrast conveniently, have significant practicality.
