Abstract
The utility model discloses a portable metallographic microscope, belonging to the technical field of the application technique of microscopes. In order to overcome the insufficiencies that the focal-length of an eyepiece and an object of traditional microscope is not easy to be adjusted, and the optimal viewing field is not favorable to be searched. The structure of the portable metallographic microscope is that an axial rod of an eyepiece barrel is provided with external threads, and the inside of a lifting fine-adjustment button is provided with internal threads; the lifting fine-adjustment button is connected with the upper end of a microscope body; a gear rack focusing structure is replaced by a thread focusing structure, and the focal-length between the eyepiece and the object can be easily adjusted; meanwhile, the microscope body is arranged on a base structure, and the microscope body can be freely moved and placed along the xy direction; the optimal viewing field is favorable to be searched. The utility model is an ideal microscope for the metallographic examination.
Description
The utility model belongs to the microscopic applications technical field.
It is with after the sample cutting that traditional metal is handled, then be placed on microscopically to check metal defect through rubbing down again, but the metal works used such as power equipment, pipe-line equipment and various petrochemical complex device therefor are carried out metal defect when checking, can not use the method for cutting sample, and can only be directly on object rubbing down, inspect, promptly metal is carried out on-the-spot metallographic examination, traditional metallographical microscope is actually the modified of conventional microscope.Adopt gear and rack structure to select best viewpoint as the focal length between lift adjustment eyepiece and the object, and microscope directly is placed on the metal object surface of examining, there are many shortcomings in this structure, as selecting eyepiece focal length with the gear driven rack structure.What of eyepiece lifting are relevant with the tooth pitch of tooth bar or gear, tooth pitch is generally the 1-2 millimeter, thus carrier wheel make at least eyepiece at the 1-2 millimeter apart from interior lifting, the lifting of this big distance is unfavorable for adjusting the focal length between eyepiece and the object.For another example, microscope is directly placed on the metal object, be unfavorable for placing, also be unfavorable for seeking arbitrarily required visual field.
Therefore, the purpose of this utility model is: design a kind of portable metaloscope, be beneficial to adjust effectively the focal length of eyepiece and object, and be beneficial to placement and seek required visual field.
The method of the novel realization purpose of this reality is: eyepiece stalk is positioned on the eyepiece stalk axostylus axostyle, the eyepiece stalk axostylus axostyle is provided with external thread, lifting fine setting button is coupling on the top of shank, be provided with internal thread in it, the internal thread of external thread on the eyepiece stalk axostylus axostyle and lifting fine setting button is spirally connected, be provided with halogen tungsten lamp in the lamp house, be provided with condenser between itself and the half-reflecting half mirror, the bottom of shank is positioned on the seat of honour, the seat of honour is the matrix seat of honour, which is provided with seat of honour dovetail slide rail, lower end, the seat of honour is provided with down seat, which is provided with dovetail tube groove, following seat is positioned on the base, base is provided with the dovetail slideway, nut is positioned at following dovetail tube groove and is fixed on the seat of honour dovetail slide rail at the seat of honour, and screw rod is positioned at nut, and screw rod one end is coupling on following, base is provided with tooth bar, there is the cylinder base frame base lower end, and the seat of honour can be along x-y to translation with following, and said structure has been realized the purpose of this utility model.
The utility model has the advantages that: adopt the screw thread lifting structure to replace the rack pinion lifting, change rough focusing apart from being the fine tuning focal length, for example: in 10 millimeters, be provided with 10 circle screw threads, so button is finely tuned in lifting and revolve three-sixth turn, then eyepiece just moves 1 millimeter, when rotation and lifting fine setting button 36 was spent, then eyepiece just moved 0.1 millimeter, thereby had improved the precision of adjusting focal length.Shank is positioned on the base and can moves freely along the x-y plane, seeks required visual field arbitrarily, has improved the convenience of using.
Below in conjunction with Figure of description and embodiment the utility model is further described.
