Abstract
The eccentric wheel type metallographical cutter fixture of the utility model, including base portion, adjustment limit part and eccentric wheel clamping part, pass through the double eccentric wheel in rotating eccentricity wheel clamping part, push the clamping plate in adjustment limit part, card is driven to have the trough of belt limiting plate and moving jaw of limited block, regular jaw movement into base portion, is clamped metallographic specimen using the dead-centre position of double eccentric wheel.The utility model has the beneficial effects that the dead-centre position using double eccentric wheel is clamped, it is ensured that uniform force when cutting metallographic specimen improves the cut quality of metallographic specimen, and adjustment is convenient, easy to maintain.
Description
Technical field
The utility model is related to it is a kind of metallic gold phase constitution is detected when use, folder for cutting metallographic specimen
Tool, belongs to technical field of measurement and test.
Background technology
Metallographic specimen cutting is the first working procedure that metallographic specimen prepares sampling, not with the Metal Cutting in standard machinery industry
Together, the requirement for being cut with own of metallographic specimen and feature.When preparing metallographic specimen, it is necessary to assure the metallographic of intercepted sample
Tissue is consistent with former component metallographic structure, and this requires require sample heated, all most by outer force effect in intercepting specimen
It measures small, avoids causing tissue change.
Metallographical cutter, since sample is by the radial load and frictional force of grinding wheel, easily causes in cutting specimen
When cutting, sample force unbalance is led to since clamping is improper, or only clamping side generates burr after leading to cut-out, influences metallographic
The cut quality of sample, and grinding wheel is fragile causes danger.
Invention content
The purpose of this utility model is that for the drawback of the prior art, a kind of eccentric wheel type metallographical cutter folder is provided
Tool, cutting efficiency and cut quality when improving metallographic specimen cutting, and simple in structure, easy to operate, reliable clamping.
The utility model technical scheme applied to solve the technical problem is：Pass through mobile trough of belt limiting plate and moving jaw
It will be positioned between regular jaw and moving jaw by cutting sample, be stuck in the limiting slot on trough of belt limiting plate with limited block,
Rotational handle band movable eccentric wheel rotates, and pushes clamping plate to move forward, sample is clamped between regular jaw and moving jaw,
In order to cut metallographic specimen.
The utility model has the beneficial effects that the dead-centre position using double eccentric wheel is clamped, it is ensured that cutting gold
Uniform force when phase sample improves the cut quality of metallographic specimen, and adjustment is convenient, easy to maintain.

Specific implementation mode
The utility model is further illustrated with reference to the accompanying drawings and examples.
The utility model is the fixture cut to metallographic specimen when a kind of preparation for metallographic specimen, by base portion, is adjusted
Whole limit part and eccentric wheel clamping part composition.
Fig. 1, Fig. 2 are referred to, base portion includes pedestal 101, regular jaw 102, trough of belt limiting plate 103, bearing block
104, bearing 105, middle (center) bearing 105 is mounted in bearing block 104, and pedestal 101 is provided with countersunk screw hole, regular jaw 102, band
Slot limiting plate 103 and bearing block 104 are provided with threaded hole, can be by regular jaw 102, trough of belt limiting plate 103 by soket head cap screw
It is separately fixed on pedestal 101 with bearing block 104.
Fig. 1, Fig. 3 are referred to, adjustment limit part includes moving jaw 201, clamping plate 202, trough of belt gag lever post 203, limit
Position block 204, wherein moving jaw 201 are fixed together by screw and trough of belt gag lever post 203, and pass through trough of belt limiting plate 103
With clamping plate 202, clamping plate 202 can be moved along trough of belt gag lever post 203, and limited block 204 is inserted into the limit of trough of belt gag lever post 203
In the slot of position.
Fig. 1, Fig. 4 are referred to, eccentric wheel clamping part includes shaft 301, eccentric wheel 302, handle 303, wherein eccentric wheel
302 are linked together with shaft 301 by general flat key, and shaft 301 can be rotated by bearing 105 around bearing block 104, shaft
301 both ends are rectangular, and one end of handle 303 is provided with square groove, can be sleeved in shaft 301.
Refer to Fig. 1~Fig. 4, before cutting metallographic specimen, by sample be put in regular jaw 102 and moving jaw 201 it
Between, it pushes trough of belt gag lever post 203 to be moved in trough of belt limiting plate 103 and clamping plate 202, drives moving jaw 201 to grips pincers
Mouth 102 moves, and so that sample is positioned between regular jaw 102 and moving jaw 201,303 one end of handle is sleeved on shaft 301
One end, rotational handle 303 drive shaft 301 and eccentric wheel 302 to rotate, and make the smaller side of 302 eccentricity of eccentric wheel towards activity
Jaw 201, mobile clamping plate 202, makes the side of clamping plate 202 close to eccentric wheel 302, limited block 204 is inserted into from clamping
In the limiting slot of the nearlyr trough of belt gag lever post in 202 other side of plate 203, rotational handle 303 is rotated with movable eccentric wheel 302, is pushed and is clamped
Plate 202 drives limited block 204, trough of belt gag lever post 203 and moving jaw 201 to be moved to regular jaw 102, clamps and is tried by cutting
Sample rotates backward handle 303 after sample is cut, and band movable eccentric wheel 302 rotates backward, and loosens clamping plate 202, takes out
Limited block 204 pulls trough of belt gag lever post 203 that moving jaw 201 is driven to move backward, can loosen clamped workpiece.
