With auxiliary mould, including access panel (1) and supporting construction (2)；The access panel (1) is horizontally disposed, and peep hole is provided with plate
(11), the access panel (1), which uses, to be supported on the observation by the magnetic material of magnet adsorption, the supporting construction (2)
The lower section of plate (1), the space between the supporting construction (2) and the access panel (1) can accommodate horizontal positioned bolt.
As the technical scheme of optimization, the supporting construction (2) includes the first supporting plate (21), two piece of first supporting plate
(21) upper end is connected to the both sides of the access panel (1), and lower end rolls to outside the both sides of the access panel (1) respectively
Tiltedly.
As the technical scheme of optimization, the supporting construction (2) also includes the second supporting plate (22), and two pieces horizontally disposed
One end of second supporting plate (22) connects the lower end of two piece of first supporting plate (21) respectively, and the other end is located at two pieces first respectively
The outside of fagging (21), the access panel (1), the first supporting plate (21) and the second supporting plate (22) collectively form " several " word
Shape.Stability Analysis of Structures, it is convenient to place bolt to be detected.
As the technical scheme of optimization, the access panel (1) and supporting construction (2) use rectangular slab, each rectangle
The width of plate is equal.
As the technical scheme of optimization, the access panel (1) and supporting construction (2) use steel plate.
Use and be welded and fixed as the technical scheme of optimization, between the access panel (1) and the supporting construction (2).
As the technical scheme of optimization, using welding between first supporting plate (21) and second supporting plate (22)
It is fixed.
As the technical scheme of optimization, two piece of first supporting plate (21) is identical with the angle between the access panel (1), folder
Angle is 120 °~160 °.
As the technical scheme of optimization, the auxiliary mould also includes some pieces of backing plates (3), and backing plate (3) pad is described
The lower section of supporting construction (2), to increase the space below the access panel (1).
As the technical scheme of optimization, the backing plate (3) uses rectangular slab.
The utility model has the advantage of：Metallographic microscope quickly, stably, can be adsorbed entirely on the auxiliary mould
Side, ensure that the imaging effect under metallographic microscope, avoid because microscope fixes shakiness, bolt caused by image is fuzzy shows
The judge error of micro-assembly robot, while substantially reduce and be used to fix the microscopical time in bolt metal lographic examination, improve detection
Efficiency.
Brief description of the drawings
Fig. 1 is the structural representation of the utility model bolt class material metal lographic examination auxiliary mould.
Embodiment
As shown in figure 1, a kind of bolt class material metal lographic examination auxiliary mould, including access panel 1, supporting construction 2 and pad
Plate 3.
Access panel 1 is using having magnetic rectangle steel plate, and size is 150mm × 150mm × 5mm, rectangle steel plate
Centre position is provided with the square peep hole 11 that size is 5cm × 5cm.
Supporting construction 2 includes the first supporting plate 21 and the second supporting plate 22, and the first supporting plate 21 and the second supporting plate 22 are equal
Use rectangle steel plate of the size for 150mm × 150mm × 5mm.
Access panel 1 is horizontally disposed；The upper end of two piece of first supporting plate 21 is connected to the both sides of access panel 1, lower end point
Not to inclination on the outside of the both sides of access panel 1；One end of two pieces of horizontally disposed second supporting plates 22 connects two pieces first respectively
The lower end of fagging 21, the other end is respectively positioned at the outside of two piece of first supporting plate 21；Access panel 1, the first supporting plate 21 and second
Supporting plate 22 collectively forms " several " font.
Angle between two piece of first supporting plate 21 and access panel 1 is 150 °.
Each junction length of side alignment of access panel 1, the first supporting plate 21 and the second supporting plate 22 is welded and fixed.
Backing plate 3 uses rectangular slab of the size for 300mm × 150mm, and the thickness of backing plate 3 can match somebody with somebody for the diameter of bolt
Plurality of specifications is put, backing plate 3 pads in the lower section of two piece of second supporting plate 22 respectively, to increase the space of the lower section of access panel 1.
In use, equivalent amount, the backing plate 3 of thickness of the same race are placed in the lower section of two piece of second supporting plate 22, by bolt water
Placing flat is in " several " figure space below access panel 1 so that access panel 1 does not contact with bolt and distance is less than 5mm；So
Peep hole 11 is directed at bolt face to be detected afterwards, promotes each piece of backing plate 3 to make its inner side and threaded bolt contacts, prevents bolt from rolling；Most
The magnetic force bearing absorption of metallographic microscope can be entered in the top of access panel 1, its object lens face peep hole 11, appropriate focusing afterwards
Row observation.
Preferred embodiment of the present utility model is the foregoing is only, it is all in this practicality not to limit the utility model
All any modification, equivalent and improvement made within new spirit and principle etc., should be included in guarantor of the present utility model
Within the scope of shield.
