Abstract
The utility model discloses an image acquisition device of a large-sized tool microscope. The image acquisition device comprises a CCD (charged coupled device) sensor and an eyepiece connecting sleeve mounted on a base plate. The CCD sensor is a miniature industrial camera, a cover plate which is connected with an inner circle of the eyepiece connecting sleeve in a threaded manner is arranged at the top end of the eyepiece connecting sleeve, the cover plate is flush with the upper surface of the base plate and provided with a diaphragm, a biconvex lenses and a plane convex lens are sequentially mounted in the eyepiece connecting cone from bottom to top, the top end of the plane convex lens is pressed onto the cover plate through a pressing tube, and a fixed lens of the miniature industrial camera faces the diaphragm on the cover plate rightly. Compared with the prior art, the image acquisition device is simple in structure, smaller in size and convenient in installation, and can be used after the eyepiece connecting sleeve is inserted into an eyepiece of the large-sized tool microscope directly.
Description
Technical field
The utility model relates to large tool microscope, is specifically related to the image collecting device of large tool microscope.
Background technology
Large tool microscope is a kind of surveying instrument commonly used in the factory.The goniometer eyepiece that this instrument is joined is mainly used in the measurement of angle, screw thread and coordinate, rotates the annular knurl handwheel and can make scale and rice word line graticule rotate the optical axis coincidence of center of rotation and rice word line point of crossing and main microscope together.
In the image collecting device of existing large tool microscope, generally be long lens barrel of design, one of this lens barrel injects in the eyepiece, ccd sensor (Charge Coupled Device is installed in the other end,), with eyepiece image focusing to the ccd sensor target surface, thereby realize image acquisition.But above-mentioned lens barrel is longer, is not easy to install and fix, and influences its result of use.
The utility model content
The technical problems to be solved in the utility model provides a kind of image collecting device of simple in structure, large tool microscope that volume is little, easy for installation.
The image collecting device of large tool microscope described in the utility model comprises ccd sensor and is installed on eyepiece connecting cylinder on the substrate, unlike the prior art be:
Described ccd sensor is the microminiature industrial camera;
Described eyepiece connecting cylinder top is provided with the cover plate that is threaded with eyepiece connecting cylinder inner ring, this cover plate is concordant with upper surface of base plate, offer diaphragm on it, biconvex lens and plano-convex lens are installed in the described eyepiece connecting cylinder from the bottom to top successively, and the top of plano-convex lens wherein is pressed on the cover plate by clamping cylinder;
The diaphragm of the fixed lens of described microminiature industrial camera on the cover plate.
In the technique scheme,
The distance of top to the biconvex lens bottom of plano-convex lens is 23～28mm in the described eyepiece connecting cylinder; Preferred 25mm.
The fixed lens of described microminiature industrial camera is flat awl aperture mirror head.
The diameter of diaphragm is 3～4mm on the described cover plate, is preferably 3.5mm.
Between described microminiature industrial camera and the substrate by support and screw retention.
Compared with prior art, this novel image collecting device is simple in structure, and volume is more small and exquisite, and is easy for installation, only eyepiece need be connected on the eyepiece that patches large tool microscope simply to get final product.
