Abstract
The utility model discloses an image measuring instrument with multiple groups of automatic rangefinders. The image measuring instrument comprises a base as well as a work platform and a lens which are arranged on the base, wherein the lens is arranged above the work platform and is at least provided with two groups of automatic rangefinders with different sensing ranges; and each group of automatic rangefinder respectively comprises a laser and a lens sensor. Therefore, because two groups of automatic rangefinders with the different sensing ranges are arranged on the lens, when one group of automatic rangefinder cannot sense the range to realize the range finding due to over great or small focal length, the other group of automatic rangefinder can be started for quickly realizing range finding for the measuring operation, and further the image measuring instrument is selective in use, wider in application range and higher in use flexibility and brings great convenience to the measuring operation of people.

Above-mentioned existing image measurer structure though can offer the effect that the user realizes rapid focus, has progressive really; But when reality is used, but find still to have many deficiencies on himself structure and the usability, cause existing image measurer in practical application, fail to reach best result of use and task performance; Its shortcoming is summarized as follows: only be provided with an automatic focusing device on the camera lens of existing image measurer, in measuring operation process, camera lens need move up and down according to the workpiece needs on the workbench at present; While, the reflection ray of this laser beam can squint under the isogonal situation of the laser instrument outgoing laser beam of automatic focusing device, the experiment proof; Camera lens is big more to the distance between the workpiece; Also just skew is big more for the reflection ray of laser beam, even exceeds the sensing range of the camera lens inductor of automatic focusing device, makes the camera lens inductor can't receive laser beam; Can't realize focusing, can't carry out thereby cause measuring operation.
The utility model content
In view of this; The utility model is to the disappearance of prior art existence; Its fundamental purpose provides a kind of image measurers with the automatic focusing device of many groups, and it can solve effectively that existing image measurer can't be realized focusing and give the measurement problem that operation is made troubles when focal length is excessive.
For realizing above-mentioned purpose, the utility model adopts following technical scheme:
A kind of image measurer with the automatic focusing device of many groups; Include pedestal and be arranged at workbench and the camera lens on this pedestal; This camera lens is positioned at the top of workbench; This camera lens is provided with the automatic focusing device that at least two groups have different sensing ranges, and each is organized automatic focusing device and has included laser instrument and camera lens inductor.
As a kind of preferred version, said laser instrument and camera lens inductor all are arranged on the circumferential lateral surface of camera lens.
The utility model compared with prior art has tangible advantage and beneficial effect, particularly, can be known by technique scheme:
Through be provided with two groups of automatic focusing devices in camera lens with different sensing ranges; When since excessive or too small and feasible wherein the one group of automatic focusing device of focal length when can't sensing range realizing focusing, can launch another and organize automatic focusing device, so that for measuring the focusing of operation Rapid Realization; Thereby make the use of product have alternative; The range of application of product is wider, uses dirigibility higher, for people's measurement operation brings more convenience.
Be architectural feature and the effect of more clearly setting forth the utility model, come the utility model is elaborated below in conjunction with accompanying drawing and specific embodiment.
