Abstract
The utility model discloses a magnetic positioning device for a metallographic-phase indentation microscope lens, belonging to a lens bracket of an industrial detection instrument. A central sleeve of the magnetic positioning device is fixed at the outer part of an objective of the metallographic-phase indentation microscope lens; an annular magnet is arranged at the bottom end of the central sleeve; a ring slot component is formed in the central sleeve; the ring slot component is formed by combining a ring slot upper body and a ring slot lower body and can slide up and down; support balls at one ends of three support rods are positioned in a ring slot of the ring slot component; the other end of each support rod is connected with a support block; and columnar magnets are arranged on the support blocks. The device disclosed by the utility model has the advantages that the central sleeve is fixed at the outer part of the objective of the metallographic-phase indentation microscope lens, and the microscope lens can be adsorbed on the plane of a magnetic-conduction detected object through the annular magnet at the end part of the central sleeve; and for a tubular or special-shaped surface, the ring slot component slides as a whole, and the support rods are regulated to drive the support blocks to move to be adsorbed on the surface of the detected object so as to quickly position the microscope lens.
Description
Technical field
The utility model relates to a kind of lens bracket of industrial detection instrument, particularly a kind of metallographic, impression microlens magnetism positioning device.
Background technology
At present, carry out at the scene metallographic, impression and detect, normally direct hand-held metallographic, impression microlens or adopt conventional three-dimensional magnetic support to fix metallographic, impression microlens, the former operation easier is large, and the surface that is only applicable to be detected is plane; And the latter, operating process is loaded down with trivial details, and inefficiency can not meet the quick and precisely requirement reliably at present on-the-spot industrial detection proposed.
The utility model content
The purpose of this utility model is that a kind of metallographic, impression microlens magnetism positioning device will be provided, solve at present at the scene metallographic, impression detect in operating process loaded down with trivial details, the problem that work efficiency is low.
The purpose of this utility model is achieved in that this magnetism positioning device comprises: annular groove upper body, annular groove lower body, fulcrum ball, support bar, back-up block, cylindrical magnetic iron, ring-shaped magnet and cylindrical central sleeve; Cylindrical central sleeve is fixed on the object lens outside of metallographic, impression microlens, and the bottom of cylindrical central sleeve has ring-shaped magnet, and the annular groove assembly is housed on cylindrical central sleeve, and the annular groove assembly is combined by annular groove upper body and annular groove lower body, can slide up and down; Fulcrum ball on three support bar one ends is arranged in the annular groove of annular groove assembly, and the other end on each support bar is connected with back-up block, is with cylindrical magnetic iron on back-up block.
Beneficial effect: owing to having adopted such scheme, the bottom that is fixed on the cylindrical central sleeve of microlens object lens outside has ring-shaped magnet, but microlens can be adsorbed on the detected material body plane of magnetic conduction, the annular groove assembly be combined into by annular groove upper body and annular groove lower body can slide up and down on cylindrical central sleeve, fulcrum ball on each support bar can slide and rotate in the annular groove of annular groove assembly, each back-up block can be the center of circle take the center of fulcrum ball, it is movable arbitrarily that back-up block to the distance in the center of circle of fulcrum ball of take is approximately in the scope of hemisphere as radius is formed, surface for cast or abnormity, by integral body slip annular groove assembly, and adjusting support bar, the drive back-up block moves, back-up block is adsorbed on the detected material surface, thereby microlens is located fast.
But metallographic, impression microlens can be adsorbed on the detected material body plane of magnetic conduction, surface for cast or abnormity, by integral body slip annular groove assembly, and adjusting support bar, the drive back-up block moves, back-up block is adsorbed on the detected material surface, can meets the request for utilization of various occasions, realize the purpose of this utility model.
Advantage: cylindrical central sleeve is fixed on the object lens outside of metallographic, impression microlens, ring-shaped magnet by its end, but metallographic, impression microlens can be adsorbed on the detected material body plane of magnetic conduction, surface for cast or abnormity, by integral body slip annular groove assembly, and regulate support bar, drive back-up block and move, back-up block is adsorbed on the detected material surface, thereby microlens is located fast.
The accompanying drawing explanation
Fig. 1 is the utility model magnetism positioning device structural drawing.
Fig. 2 is the application drawing of the utility model in the column tube surface.
In figure: 1, annular groove upper body; 2, annular groove lower body; 3, fulcrum ball; 4, support bar; 5, back-up block; 6, ring-shaped magnet; 7, cylindrical central sleeve; 8, cylindrical magnetic iron; 9, microlens.
Embodiment
Embodiment 1: this magnetism positioning device comprises: annular groove upper body 1, annular groove lower body 2, fulcrum ball 3, support bar 4, back-up block 5, ring-shaped magnet 6, cylindrical central sleeve 7, cylindrical magnetic iron 8; Cylindrical central sleeve 7 is fixed on the object lens outside of metallographic, impression microlens 9, the bottom of cylindrical central sleeve 7 has ring-shaped magnet 6, the annular groove assembly is housed on cylindrical central sleeve 7, and the annular groove assembly is combined by annular groove upper body 1 and annular groove lower body 2, can slide up and down; Fulcrum ball 3 on three support bar 4 one ends is arranged in the annular groove of annular groove assembly, and the other end on each support bar 4 is connected with back-up block 5, band cylindrical magnetic iron 8 on back-up block 5.
Cylindrical central sleeve in device is fixed on the object lens outside of metallographic, impression microlens, ring-shaped magnet by its end, but metallographic, impression microlens can be adsorbed on the detected material body plane of magnetic conduction, surface for cast or abnormity, by integral body slip annular groove assembly, and regulate support bar, drive back-up block and move, back-up block is adsorbed on the detected material surface, thereby microlens is located fast.
