Description
Technical field
Utility model device is related to metallographic specimen field of polishing, in particular to a kind of to use laboratory polishing machine polishing gold
The device of phase sample.
Background technique
In recent years, the emergence with NPD projects, new technology with the rapid development of science and technology, property of the people to material
Increasingly harshness, the quality of material property can be required to be related to a nation's security, be related to the happiness of the people, therefore more
Enter in material laboratory come more scientific talents, generally requires to see the microstructure of material in the research of material
Can the quality that examined, and prepare metallographic specimen is related to other equipment clearly express the microstructure of material, one in laboratory
As be manually to prepare metallographic specimen, not only wasted the time of experimenter in this way but also be difficult to prepare good sample, and utilized laboratory
In common polishing machine, design a kind of device used in the lab, which can replace experimenter prepare metallographic examination
Sample can obtain good metallographic specimen and save the time of experimenter.
Summary of the invention
In view of the above problems, the utility model designs a kind of device using laboratory polishing machine polishing metallographic specimen.
The utility model mainly includes rack, water pot, fixture a, fixture b, spring a, spring b, nut a, nut b, spring a
It covers on the axis of fixture a, the axis of fixture a passes through corresponding hole in rack, and nut a is fixed on the shaft end portion of fixture a, spring b set
On the axis of fixture b, the axis of fixture b passes through corresponding hole in rack, and nut b is fixed on the shaft end portion of fixture b, water pot welding
In the top in frame central hole, the hole of water pot bottom is connected to the centre bore of rack, and the water energy in water pot enough passes through water pot bottom
Hole and frame central hole flow to sand paper center.
Utility model device includes following technical solution: generally there are the sample of two kinds of shapes, a kind of samples in laboratory
It is the cylindrical specimens inlayed using pointing machine, the diameter of cylinder is certain, and another sample is rectangular-shape sample, sample
Side is vertical with face to be polished, and for the sample of two kinds of shapes, we devise fixture a and fixture b, and fixture a is for clamping
Cuboid sample, fixture b is for clamping the cylindrical specimens inlayed, when polishing machine polishes to sample, in water pot
The centre bore that water energy enough passes through rack flows into sand paper center, and under the action of the centrifugal force, water flow around, is passing through sample buffed surface
When sample can be cooled down, so the temperature of sample will not steeply rise, to influence the performance of buffed surface, obtain good
Sample.
The utility model advantage more next than existing device band and good effect:
1, the device replaces the sample of hand clamping processing using mechanical clamp, and the velocity of rotation of sand paper is stablized, so that polishing
Surface quality it is high.
2, the device uses mechanical grinding sample, instead of the manual operations of laboratory technician, to reduce process time, saves
Cost.
3, the apparatus structure is simple, easily operated, practical.
Detailed description of the invention
The present invention will be further described with reference to the accompanying drawing.
Fig. 1 is the preferred three-dimensional view of one preferred embodiment of this utility unit；
Fig. 2 is the working view of one preferred embodiment of this utility unit；
Fig. 3 is that the fixture a of one preferred embodiment of this utility unit clamps workpiece partial view.
Fig. 4 is that the fixture b of one preferred embodiment of this utility unit clamps workpiece partial view.
In figure: fixture a (1), spring a (2), nut a (3), water pot (4), rack (5), nut b (6), spring b (7), folder
Have b (8), sand paper (9), cuboid sample (10), cylindrical specimens (11), polishing machine (12).
Specific embodiment
As shown, spring a (2) covers on the axis of (1) fixture a, the axis of fixture a (1) passes through corresponding on rack (5)
Hole, the shaft end portion of nut a (3) stationary fixture a (1), spring b (7) cover on the axis of (8) fixture b, and the axis of fixture b (8) passes through machine
Corresponding hole on frame (5), the shaft end portion of nut b (6) stationary fixture b (8), water pot (4) are welded on the upper of rack (5) centre bore
Side, the hole of water pot (4) bottom are connected to the centre bore of rack (5), and the water energy in water pot (4) enough passes through the hole of water pot (4) bottom
Sand paper (9) center is flowed to rack (5) centre bore, side is mobile axially outward by fixture a (1), and spring a (2) is compressed, and loads
Cuboid sample (10) arrives between fixture a (1) and rack (5), the face protrusion fixture a for needing to polish on cuboid sample (10)
(1) end face, after unclamping fixture a (1), spring a (2) will push fixture a (1) axial movement, and cuboid sample (10) is pressed from both sides
Tightly, sample (1) needs the face polished tightly to be affixed on sand paper (9), and by fixture b (8), side is mobile axially outward, spring b (7)
It is compressed, loads cylindrical specimens (11) and arrive between fixture b (8) and rack (5), the face for needing to polish on cylindrical specimens (11)
The end face of fixture b (8) is protruded, after unclamping fixture b (8), spring b (7) will push fixture b (8) axial movement, cylindrical specimens
(11) it is clamped, cylindrical specimens (11) need the face polished tightly to be affixed on sand paper (9).
When the device is operated, polishing machine (12) drives sand paper (9) rotation with certain speed, at this time cuboid sample (10)
Need the face polished to be polished by sand paper (9) with cylindrical specimens (11), the water in water pot (4) by the hole of water pot (4) bottom and
The centre bore of rack (5) flows to sand paper (9) center, and the water at sand paper (9) center flows around under the influence of centrifugal force, when
When water is by the cuboid sample (10) being polished and cylindrical specimens (11), to cuboid sample (10) and cylindrical specimens
(11) it is cooled down, so the temperature in the face that cuboid sample (10) and cylindrical specimens (11) are polished will not steeply rise,
To obtain good cuboid sample (10) and cylindrical specimens (11).
