Description
Technical Field
The utility model relates to a fixed auxiliary device of sheet metal metallographic specimen belongs to metal metallographic system appearance technical field.
Background
Metallography system appearance has important meaning to the organizational structure of technical staff research metal material, needs to cut into the sample of 20 millimeters square before the metallography system appearance of sheet product, for the convenience of later stage grinds the operation, needs to carry out the inlaying machine to the sample after the cutting and inlays the operation, makes the sample inlay the sample section of being convenient for and polishes the operation, and the sample of inlaying is ground on emery wheel is polished or abrasive paper and is ground the appearance. The mosaic machine has high purchase and use cost, and the mosaic operation can be completed within a certain time.
Some tests require specificity on metallographic sample preparation, for example, the corrosion resistance of the galvanized sheet is influenced by different scratch depths of the surface of the galvanized sheet. At this time, it is necessary to observe the degree of damage of the plated region of the galvanized sheet section. The traditional metallographic sample preparation method is adopted, the blade cuts a zinc layer, the inlaying machine inlays a sample, grinds the sample and observes a metallographic microscope, and because the thickness of the zinc layer is very thin, the thickness of the zinc layer of the galvanized sheet of hot-base automobiles and household electrical appliances in a steel mill is generally less than 25 mu m, and in addition, the zinc layer of the galvanized sheet is very easy to fall off in the sample grinding process, so that the cutting position of the initial coating cannot be found.
When the requirements on the metallographic sample preparation of the material are very high, for example, the thickness, distribution and the like of the iron-aluminum alloy phase of a hot-base galvanized product in a continuously-produced steel mill have important significance on the corrosion resistance of the galvanized plate, and the requirements on the metallographic sample preparation of the galvanized plate are strict. Because the iron-aluminum alloy phase is very thin and about 1-2 mu m, substances which can corrode the iron-aluminum alloy phase, such as emulsion, water and the like, cannot be contacted in the metallographic sample grinding process, and the method is not suitable for inlaying operation of an inlaying machine, so that the galvanized plate is required to shear a metallographic sample by using a plate shearing machine and grind the sample directly by hand, and great trouble is brought to grinding the sample by directly holding the sample by hand manually.
To above-mentioned drawback, need to develop a fixed auxiliary device of sheet metal metallographic specimen urgently, convenient to use, and can solve the sheet metal metallographic specimen preparation difficult problem when being not suitable for the inlaying machine to inlay the operation.
SUMMERY OF THE UTILITY MODEL
An object of the utility model is to provide a fixed auxiliary device of metallography system appearance sample to the drawback of prior art to improve the not enough of laboratory metallography system appearance condition, improved efficiency and the convenience that the metallography ground the appearance.
The technical scheme of the utility model is that:
the utility model provides a fixed auxiliary device of sheet metal metallographic specimen, its characterized in that includes clip, gasket, handle, clamp bolt, cushion, bolt, the clip is for the tetragonal body that has trapezoidal breach, and trapezoidal breach is the narrow setting in outer wide, the shape of gasket and the trapezoidal breach shape phase-match of clip assemble in the trapezoidal breach of clip, the cushion is the cuboid shape, assembles in the gasket, the terminal surface of gasket, cushion and the terminal surface parallel and level of clip, clamp bolt runs through the assembly in the both sides of clip through the screw, the handle sets up in the top of clip, and the bottom center of handle is provided with the bolt, through bolt and clip, gasket fastening connection.
As the auxiliary device for fixing the sheet metallographic specimen, the handle is in a hemispherical shape with a flattened top.
As the thin plate metallographic specimen fixing auxiliary device, the trapezoid angle of the trapezoid notch of the clamp is 2-4 degrees.
As the thin plate metallographic sample fixing auxiliary device, the thickness of the cushion block is 8-12 mm.
According to the auxiliary device for fixing the sheet metallographic specimen, the distance between the cushion block and the gasket is 1.5-2.5 mm.
The utility model has the advantages that: when the clamp is used, the grip is held by hand to grind the sample. The method has the advantages of convenient operation, safety, reliability, low manufacture cost of the clamp, test cost saving, convenient sample preparation, great improvement of the efficiency of the prepared metallographic specimen and quality improvement.

Detailed Description
The invention will be further explained by way of example with reference to the accompanying drawings.
Referring to fig. 1-2, the utility model discloses a handle 3, clip 1, gasket 2, cushion 5, clamp bolt 4, plasticine 6 is jammed in gasket 2 and cushion 5 centre, and handle 3 sets up in the top of clip 1, and the bottom of handle 3 is provided with bolt 8, through bolt 8 and clip 1, cushion 5, gasket 2 fastening connection. When the clamping bolt 4 is rotated, the gasket 2 can move, so that the test piece 7 is clamped. The trapezoidal angle of the trapezoidal notch of the clip 1 is 3 degrees. The spacer 5 has a thickness of 10 mm. The distance between the cushion block 5 and the gasket 2 is 2 mm.
The working process of the positioning tool comprises the following steps: the clamp 1 is turned over, the handle 3 faces downwards, a certain amount of plasticine 6 is filled between the gasket 2 and the cushion block 5 according to the size of the sample 7, two sides of the cushion block 5 can be simultaneously provided with one sample 7 respectively, and after the samples are flattened by the sample presser, the sample 7 is fixed by the gasket 2 and the cushion block 5 by rotating the clamping bolt 4. When the sample pressing machine is not used, the handle 3 can be held by hand, so that the sample 7 is contacted with the platform, and the sample 7 is horizontal to the horizontal plane. The clamping bolt 4 is turned to fix the sample 7 more firmly. When grinding the sample, only the handle 3 is needed to be held by hand to grind the sample 7 on the grinding wheel, the abrasive paper and the polishing cloth according to the requirement. Because the handle 3 is above flat, the sample after polishing can directly invert whole anchor clamps on the metallographic microscope platform, uses the metallographic microscope directly to carry out the cross-section observation to metallographic specimen 7, need not to take off the sample.
When the clamp is used, the grip 7 is held by hand to grind the sample. The method has the advantages of convenient operation, safety, reliability, low manufacture cost of the clamp, test cost saving, convenient sample preparation, great improvement of the efficiency of the prepared metallographic specimen and quality improvement.
