The device comprises a laser generator, a first measuring lens and a second measuring lens, wherein light beams emitted by the laser generator are superposed with a reference focus point of the first measuring lens and vertically shot onto a measuring plane; the second measuring lens is arranged in a relatively inclined mode, and the reference focus point of the second measuring lens is crossed and converged on the reference focus point of the first measuring lens. The utility model discloses utilize first measuring lens to form the facula to laser generator on the measuring plane and carry out the location measurement, and the second measuring lens slant is measured to utilize the second measuring lens focus point horizontal offset on the measuring plane to obtain the vertical migration numerical value of facula on the measuring plane, this simple structure, it is convenient, accurate to measure, and the error is little.
Description
Technical field:
The utility model relates to field of measuring technique, refers in particular to a kind of laser measuring apparatus.
Background technology:
Along with the development of micro-electromechanical technology, the precision positioning measurement has been proposed more and more higher requirement, thereby traditional vernier caliper or spiral measuring instrument are difficult to satisfy measurement requirement.Photoelectric measuring instrument appears subsequently, it utilizes image to seize device (as CCD) is electronic signal with the video conversion of measured object, electronic signal is delivered to computer again, picture processing chip by computer is shown enlarged in image on the display, utilize corresponding seizure of computer three-dimensional coordinate to measure again, this mode can reduce measuring error, promotes measuring accuracy.Traditional photoelectric measurement instrument mainly is the measurement plane size, for the measurement of height value, then has various dissimilar metering systems, but measurement is stable not high, and error is bigger, brings inconvenience to actual production work, so necessity of improvement is arranged really.
The applicant is because the disappearance and the inconvenience of above-mentioned known measuring instrument, the spirit of adhering to the research innovation, keeping on improving, utilize its professional eye and professional knowledge, work out a kind of applied range, meet industrial utilization and can effectively promote the laser measuring apparatus of measuring effect.
The utility model content:
The purpose of this utility model be to provide a kind of simple in structure, measure laser measuring apparatus easily.
For achieving the above object, the utility model adopts following technical scheme:
A kind of laser measuring apparatus includes a laser generator, first and measures the camera lens and the second measurement camera lens, and the light beam that laser generator sends overlaps with the first benchmark focus point of measuring camera lens and vertically is mapped on the measurement plane; Second measures camera lens is oblique relatively setting, and the second benchmark focus point intersection of measuring camera lens meets at first and measures on the benchmark focus point of camera lens.
The light beam that described laser generator sends overlaps and vertically is mapped on the measurement plane with the first benchmark focus point of measuring camera lens by reverberator reflection back.
The utility model utilizes the first measurement camera lens that laser generator is formed hot spot on measurement plane and positions measurement, and the oblique measurement of the second measurement camera lens, and utilize the second measurement lens focus point to obtain the vertical shift numerical value of hot spot on measurement plane at the horizontal offset on the measurement plane, this is simple in structure, it is convenient, accurate to measure, and error is little.
Description of drawings:
Accompanying drawing 1 is a structural principle synoptic diagram of the present utility model.
Embodiment:
Below in conjunction with accompanying drawing the utility model is further specified:
Consult shown in Figure 1, the laser measuring apparatus that the utility model provides, include a laser generator 1, first and measure the camera lens 2 and the second measurement camera lens 3, the light beam that laser generator 1 sends overlaps and vertically is mapped on the measurement plane 4 with the first benchmark focus point of measuring camera lens 2; Second measures camera lens 3 is oblique relatively setting, and the second benchmark focus point intersection of measuring camera lens 3 meets at first and measures on the benchmark focus point of camera lens 2.Among the embodiment, the light beam that laser generator 1 sends can overlap also with the first benchmark focus point of measuring camera lens 2 by a reverberator 5 reflection backs and vertically be mapped on the measurement plane 4 simple in structure, easy enforcement.
During enforcement, fix the position relation between laser generator 1, the first measurement camera lens 2 and the second measurement camera lens 3, first measures camera lens 2 and second measures camera lens 3 connection corresponding computers.Under the normality, the second benchmark focus point intersection of measuring camera lens 3 meets at first and measures on the benchmark focus point of camera lens 2, as the point of the O among Fig. 1, the first measurement camera lens forms hot spot to laser generator and positions measurement on measurement plane, can know that thus laser generator 1 forms the position of hot spot.When occurring the hot spot height change originally, the light beam that laser generator 1 sends overlaps with the first measurement focus point of measuring camera lens 2 and vertically is mapped on the measurement plane 4 ', form O ' point, and at this moment, because second measures camera lens 3 oblique measurements, it measures the horizontal-shift of focus point on measurement plane 4 ', form O " point; read O on computers " horizontal range L between point and the O ' point, can utilize the L value to calculate vertical height H between O ' point and the O point, promptly utilize the second measurement lens focus point to obtain the vertical shift numerical value of hot spot on measurement plane at the horizontal offset on the measurement plane, reach the measurement of height value, this is simple in structure, and it is convenient to measure, accurately, error is little.
Certainly, above embodiment is the utility model preferred embodiment only, is not to limit practical range of the present utility model with this, so every principle according to the utility model is done the equivalence variation or modified, and all should be covered by in the protection domain of the present utility model.
