Description
Technical field
The utility model belongs to the Electrochemical Measurement Technology field, particularly a kind of galvanochemistry test piece anchor clamps.Be used in particular for the electrochemical property test of metal material under different temperatures.The electrochemical property test that is used for metal material reduces the loaded down with trivial details operation in the electrode fabrication process, reduces working strength, and environmental contamination reduction is eliminated the defective that produces in the traditional electrode encapsulation process, directly the chemical property of metal testing plate is tested.
Background technology
When carrying out the electro-chemical test of sheet metal, sheet metal need to be encapsulated, be made into electrode.At first need to process the test piece in 10 * 10mm cross section, one of them face is as tested, and one side is polished with sand paper in addition, removes oxidation products, exposes the metallic matrix of conduction, then copper conductor is welded on the parent metal.Tested face is sticked adhesive tape, in order to avoid damage tested in the electrode fabrication process.Tested the facing down of sample is placed on the glass plate, with epoxy resin or silica gel tested all surfaces in addition encapsulated, behind resin drying, remove adhesive tape, clean tested of test piece with absolute ethyl alcohol, and use the acetone degrease, then carry out electrochemical measurement.This process operation is loaded down with trivial details, and the material that needs is complicated, and harmful to environment, and the electrode fabrication time is longer, inefficiency.And when the test piece of preparation coated layer, easily destroy the coated layer surface, thereby have influence on test result.
A lot of electro-chemical test process times are longer, electric current is larger, surface state with the havoc sample, even sheet metal specimens punctured, substantially scrap through the sample after this test, can not be used as again other measurements, need a plurality of samples of preparation to satisfy test request, further increase so again workload, reduced test efficiency.In addition, traditional packaging technology also easily produces bubble etc. in the edge of test piece, affects the sealing of encapsulation, causes the deviation of test findings.
Therefore, make a kind of galvanochemistry test piece encapsulation stationary installation of convenient operation, reduce processing step and material consumption in the electrode package process, significantly improve the work efficiency of electro-chemical test.
Summary of the invention
The purpose of this utility model is to provide a kind of galvanochemistry test piece anchor clamps.
The utility model comprises: lower clamp formwork 1, fastening bolt holes 2, O type circle draw-in groove 3, test piece platform 4, O type circle 5, upper clamp formwork 6, test piece packing ring 7 and fastening bolt 8.4 jiaos of places of lower clamp formwork 1 are provided with fastening bolt holes 2, have cylindric table top, cylindric mesa edge to be provided with O type circle draw-in groove 3 on the lower clamp formwork 1, and O type circle 5 is fixed on the lower clamp formwork 1 by O type circle draw-in groove 3, and the afterbody of test piece platform 4 passes the center of lower clamp formwork 1 and exposes 3mm.4 jiaos of places of upper clamp formwork 6 are provided with fastening bolt holes 2, the center of upper clamp formwork 6 is provided with 1 circular port, and test piece packing ring 7 is placed with circular port is concentric, is positioned at the bottom of upper clamp formwork 6 central round orifice, fastening bolt 8 is positioned at fastening bolt holes 2, and lower clamp formwork 1 is connected with upper clamp formwork by fastening bolt 8 connections.
Test piece platform 4 is T-shaped, and afterbody connects external wire.
Test piece platform 4 is conductive material, such as stainless steel or copper etc.
After upper clamp formwork and lower clamp formwork compressed, test piece platform 4 and test piece close contact were pressed in it on test piece packing ring 7.O type circle 5 and the cylindrical outer surface of lower clamp formwork 1 and the internal surface of column close contact of upper clamp formwork 6 play sealing function; Test piece packing ring 7 and test piece 9 and upper clamp formwork 6 close contacts also play sealing function; Test piece 9 all parts except test area will be closed in the cavity like this, with solution isolation, reach the packaging effect identical with the material such as epoxy resin.The internal diameter control of the test area of test piece by test piece packing ring 7, the size of test piece can increase, can in the cylinder of upper clamp formwork, move, so as behind one-shot measurement the test position of conversion test piece, carry out different electrochemical property tests.
The utility model has the advantage of, this apparatus structure is simple, and convenient operation can be changed test piece or conversion test position easily, has reduced the complicated processes of electrode package, has improved work efficiency.And be in sealed environment because this device compresses rear test piece, can directly immerse and carry out heating water bath in the solution.
