Description
Technical field
The utility model belongs to Analysis of Metallic Materials equipment technical field, and in particular to a kind of for grinding metallographic specimen
Fixture.
Background technique
Metallographic Analysis refers to the microscopic structure that metal is observed under the higher optical metallographic microscope of amplification factor, i.e. material
Form, size and the content of each constituent are that the testing of materials is studied with the relationship between research material ingredient, tissue and performance
One of important means.To observe that material is true, clearly microscopic structure, first has to prepare metallographic specimen, observe
Face must it is smooth, and as mirror surface no marking, without spot.The preparation of metallographic specimen includes sampling, inlaying, grinding, polishing, soaking
Several steps such as erosion.Wherein grinding need to be by corase grinding, fine grinding and fine grinding.Corase grinding needs to spend in metallographic specimen whole preparation process
Take a large amount of time and manpower, corase grinding effect is bad, will increase fine grinding, fine grinding and polishing time, will appear after notably polishing recessed
Hole, scratch etc., will cause illusion when serious.Thus it is guaranteed that it is to improve sample preparation efficiency and guarantee that metallographic specimen, which quickly polishes,
The key of quality.Presently, there are main problem metallographic specimen it is more, sample needs polish on abrasive machine one by one by hand,
First not can guarantee the flatness of sample, and the second sample preparation inefficiency, there are biggish security risks for third.
Utility model content
For above-mentioned problems of the prior art and deficiency, the utility model, which provides, is used for quick grinding metallographic specimen
Fixture, to solve the problems, such as sample preparation inefficiency and not can guarantee sample flatness.
To achieve the above object, the utility model provides the following technical solutions:
A kind of fixture for grinding metallographic specimen, including plate, screw rod, snap-gauge and cushion block, two sides are put in parallel on plate
One group of cushion block is set, places snap-gauge on cushion block, multiple groups round tube hole is offered on the snap-gauge between cushion block, the snap-gauge is by two pieces
Splicing offers screw hole into plate in snap-gauge long side, and the screw hole of two boards corresponds to each other, and is tightened with the screw rod across screw hole
Or it unclamps.
Further, the length of the plate is 500mm*200mm*20mm.
Further, the round tube hole diameter is 30mm.
Further, the length of the cushion block is 80mm*15mm*3mm.
Further, the plate is made of carbon constructional steel plate.
Compared with prior art, the utility model has the beneficial effects that
The plate and multiple round tube holes of the utility model setting, plate can ensure that multiple samples are maintained at same level
On, multiple round tube holes are once placed multiple samples and are ground on grinding machine, and metallographic sample is substantially improved and grinds efficiency, and guarantees
The flatness of sample, two pieces of snap-gauges docking are convenient for placing and sample of taking, using two screw rods for adjusting between two pieces of snap-gauges
It is shorter to grind sample time using the utility model, sample preparation efficiency can be improved for gap and fixed sample.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model；
Fig. 2 is the schematic cross-sectional view in Fig. 1.
In figure: 1. plates, 2. screw rods, 3. snap-gauges, 4. round tube holes, 5. cushion blocks, 6. screw holes.
Specific embodiment
The utility model is described in detail with reference to the accompanying drawings and detailed description.
As shown in Figs. 1-2, a kind of fixture for grinding metallographic specimen, including the plate 1 made of carbon constructional steel plate,
Screw rod 2, snap-gauge 3 and cushion block 5, length be 500mm*200mm*20mm plate 1 on two sides be placed in parallel one group of length and width,
The cushion block 5 of a height of 80mm*15mm*3mm, snap-gauge 3 is placed on cushion block 5, and it is straight to offer multiple groups on the snap-gauge 3 between cushion block 5
Diameter is the round tube hole 4 of 30mm, and snap-gauge 3 is spliced by two pieces, and screw hole 6, the screw hole of two boards are offered into plate in 3 long side of snap-gauge
6 correspond to each other, and are tightened or unclamped with the screw rod 2 across screw hole 6.
The utility model is placed on 1 liang of plate survey when specifically used, by two cushion blocks 5, and two pieces of snap-gauges 3 are placed in cushion block 5
On, the flour milling of multiple samples is successively put upside down and is contacted the sample on plate 1 in round tube hole 4, two pieces of snap-gauges 3, which are aligned, simultaneously to be tightened
Screw rod 2 makes sample firm grip, is placed on grinding machine and is ground after overturning, and multiple samples just polish after five minutes, then unclamps
Screw rod 2, next procedure can be carried out by taking out sample.
