Background technology
Metallographic test be metal material industry be commonly used to observation microstructure of metals test method, the purpose is to by
Microstructure observation's result of metallographic test judges its physical properties and mechanical performance.It puts into production in material the advance of line
The metallographic experiment of row material timely finds and judges the defects of material internal microstructure is with the presence or absence of slight crack, impurity, to enterprise
The reasonable arrangement and plan of industry manpower and materials and production cost have a very important significance.
Metallographic test contains sample preparation and metallographic observation two parts, and wherein metallographic specimen preparation is the base of metallographic observation
Plinth.The preparation of metallographic specimen at present, especially thin plate class metalloid sample, usually press several samples in sample pointing machine
It is inlayed according to certain putting in order, sample preparation more specification, sample mass is higher.However, such sample system
Standby process needs special sample to inlay instrument and auxiliary equipment, and what need to be made adequate preparation inlays the accessories such as powder, cost
It is higher.In addition, this sample preparation generally requires waiting 3~7 minutes or so, and some are more than edge specimen chamber diameter dimension
Sample can not inlay.The working efficiency and means of metallographic test need to be further improved.
Invention content
The purpose of this utility model is to provide a kind of simple metallographic sample preparation fixtures, solve current over dimensioning sample and are inlayed
The problem of embedding instrument and auxiliary equipment limitation can not inlay preparation.
A kind of simple metallographic sample preparation fixture, is made of fixing device and clamping device, including left fixed block 1, right fixed block
2nd, inner screw 3, external screw rod 4, inner screw nut 5 and outboard nut 6.Left fixed block 1 passes through inner screw 3 and external screw rod 4 and right fixation
Block 2 is connected, and inner screw 3 is connected with inner screw nut 5, external screw rod 4 is connected with outboard nut 6, inner screw 3, external screw rod 4,
Inner screw nut 5 and outboard nut 6 form clamping device；Left fixed block 1 and right fixed block 2 form fixing device；
Left fixed block 1 multiplies roomy area in face of neat and parallel with the length of right fixed block 2, and left fixed block 1 and right fixed block 2 are each
There is the 1 long face for multiplying thickness to grind face to be smooth；
The size of left fixed block 1 and right fixed block 2 is 30~60mm long * 15~25mm wide * 2~10mm thick；
Left fixed block 1 and right fixed block 2 respectively have 2 screw holes, and 4 screw holes are opposite two-by-two；Screw hole on 2 fixed block length axis
Position is placed in the middle, pitch-row d1For 28~58mm, screw hole is located at both sides, pitch-row d on wide axis2For the half of≤fixed block width, pitch-row
d2For 7.5~12.5mm；
Inner screw 3 and 4 length of external screw rod are 20~60mm, a diameter of 3~5mm；
Fixing device and clamping device material are steel, hardness HRC ＞ 30.
The utility model has the advantage of：Clamp structure is simple, use and simple operation, suitable for different-thickness size
Steel plate and thin plate.The process that the process of pointing machine edge sample is omitted and the big sample of size is cut into small sample, is carrying
The cost of metallographic test is reduced while high working efficiency.
