Description
Technical field
The utility model relates to metallographic specimen preparation technical fields, and in particular to a kind of more function for metallographic specimen preparation
It can fixture.
Background technique
During metal lographic examination, the too small such as steel wire of specimen size, tiny spring, thin plate or detection project are special such as
Then thickness of coating, surface gross decarburization thickness degree, gear surface tissue etc., which need inlay to sample, carries out grind away, polishing
Deng.Common there are two types of sample method for embedding: cast setting method and resin inlaying process.The method of cast setting is due to easy to operate
It does not waste inlay again and does not need to buy inlaying equipment, be always the selection in many laboratories.The card of laboratory cast setting at present
Have use situation: laboratory cast setting fixture mostly uses b type in GB/T13298-2015 " the metal microstructure method of inspection "
It is as illustrated in fig. 1 and 2 with the fixture of c type.Such fixture is current laboratory needle two kinds of sample fixtures common to small sample, b type
The main application method of fixture is through a bolt presses on the inner wall of small round tube by tiny circular specimen, and C-shaped fixture is
Thin plate sample is clamped between two pieces of plates, subsequent grinding → polishing → corrosion → observation is then carried out.But exist with
Lower deficiency: 1, b type fixture only leans on a bolt presses due to sample, may be due to fixed sample in subsequent process of lapping
Fastening force is not enough or uneven, causes sample that can tilt, and generates sample chamfering situation, and the metallographic observation that will affect the later period is especially
Thickness of coating, surface gross decarburization thickness degree, gear surface tissue etc..2, sample is ground in tiny round test block and thin plate test block
When, need two sets of fixtures, using trouble, process is cumbersome.
Utility model content
The purpose of this utility model is deficiency to solve above-mentioned technical problem, provide it is a kind of for metallographic specimen preparation
Multifunctional clamp, Multifunctional clamp can be stablized with grabbing thin plates sample and tiny circular specimen, clamping effect, and sample can be more preferable
Ground is fixed, and is not easy to tilt.
The deficiency of the utility model to solve above-mentioned technical problem, used technical solution is: one kind is tried for metallographic
The Multifunctional clamp of sample preparation, including jig body and puller bolt, the upper surface of jig body are provided with for placing sample
Clamp groove, the Multifunctional clamp further includes the pressing plate that can be placed between sample and puller bolt, clamp groove inner wall tool
There are the first clamping station and the second clamping station, the first clamping station is vertical plane, and the second clamping station is vertical arc
Face, and side wall opposite with the first clamping station and the second clamping station in jig body is respectively arranged with tapped through hole, holds out against
Bolt can screw in tapped through hole and hold out against sample by pressing plate.
As a kind of advanced optimizing for Multifunctional clamp for metallographic specimen preparation of the utility model: first folder
It holds between station and the second clamping station in 90 ° of angle settings.
Beneficial effect
One, the fixture of the utility model increases sample pressing plate, improves the chucking power to sample, keeps sample preferably solid
It is fixed, it is not easy to tilt, chamfering after capable of preventing sample from tilting guarantees that sample making course is gone on smoothly, and has preferably when examining
Observing effect；
Two, there are two clamping station, the first clamping station is in clamp groove inner wall machine for the fixture setting of the utility model
The plane of machine-shaping can then be used to clamp by the plane and pressing plate with grabbing thin plates and rectangular test block, the second clamping station
Tiny circular specimen achievees the effect that a fixture is applicable in multiple types sample；
Three, the fixture of the utility model is easy to operate, and sample is fitted closely with fixture inner wall, be easy to observe sample end face and
Whether fixture end face is concordant.

Specific embodiment
Further the technical solution of the utility model is illustrated below in conjunction with specific embodiment.
A kind of Multifunctional clamp and metallographic specimen preparation method for metallographic specimen preparation, as shown in Figures 3 and 4: card
Tool includes jig body 1 and puller bolt 2, and the upper surface of jig body 1 is provided with the clamp groove 3 for placing sample 6.It is more
Function fixture further includes the pressing plate 4 that can be placed between sample 6 and puller bolt 2, and 3 inner wall of clamp groove has the first clamping station
301 and second clamping station 302, the first clamping station 301 be vertical plane, the second clamping station 302 is vertical cambered surface,
In 90 ° of angle settings between first clamping station 301 and the second clamping station 302.And in jig body 1 with the first clamping station
301 and second the opposite side wall of clamping station 302 be respectively arranged with tapped through hole 5, puller bolt 2 can screw in tapped through hole 5
And sample 6 is held out against by pressing plate 4.
The method for carrying out metallographic specimen preparation using above-mentioned fixture, comprising the following steps:
S1: wire cutting sampling size is carried out to sample according to GB/T10561-2005 are as follows: 25mm*25mm*25mm uses pre-grinding
Machine polishes wire cutting trace and adds water to prevent from overheating simultaneously；
S2: puller bolt is screwed in the corresponding tapped through hole of the first clamping station, and sample is then close to the first clamping
Station, and pressing plate is placed between sample and puller bolt head, platen clamp sample is made by turn bolt, carries out subsequent metallographic
Sample preparation；
S3: carrying out fine grinding processing to sample, often changes primary particle size thinner sand paper sample is rotated by 90 ° and carry out essence again
Mill, until last scratch covering is complete；
S4: polishing the sample after fine grinding, is rinsed with water while specimen surface is remained with absorbent cotton dirty after polishing
Object (mainly polishing mud and other dirts) scrubs, then uses alcohol rinse specimen surface (evaporation rate for accelerating water),
Sample is finally tilted (to note when inclination: along the top corner angle of sample when being rinsed with alcohol dropper, making the dirt on each surface will not
Other surface is influenced, especially will not influence detected surface), and (air port of hair dryer is protected with surface is observed with hair dryer
Hold certain angle acceleration of alcohol evaporation rate) sample is dried up；
S5: the sample after drying is subjected to corrosion treatment, etch will not generate corrosion unevenly, cause " microstructure segregation "
Illusion.With sample is tilted after corrosion, successively with water and alcohol, corner angle are rinsed sample above sample, finally with blowing
Machine dries up sample.
