The utility model is a kind of to be used to test the electrochemical anchor clamps of sheet metal, includes set bolt, upper clamp formwork, sheet metal to be measured, sample bench, stressed spring, lower clamp formwork and metal conducting bar.It is characterized in that: the center of upper clamp formwork has a stepped appearance vestibule, and top is the cylindrical bore of larger aperture, and the middle part is for being shrunk to duct-like vestibule, and the bottom then is very little square square hole; The circular hole on top and vestibule are the inlet and storage place of pouring into medium solution; Middle part pipe-like vestibule is adorned salt bridge in order to fixed-piping; The small square hole of bottom is aimed at the sheet metal to be measured on sample bench when clamp; The central upper portion position of lower clamp formwork has a cylindrical bore, is provided with stressed spring in it, is provided with above the stressed spring to place sheet metal sample bench to be measured; The sample bench center is provided with small sircle hole, and corresponding also has small sircle hole in the lower clamp formwork bottom, and metal conducting bar passes through stressed spring intermediate space and is fixed in described two small sircle holes; The top of metal conducting bar maintains an equal level with the upper surface of sample bench and contacts at grade and with the lower surface of sheet metal to be measured; Between upper clamp formwork and lower clamp formwork, in the Qi Sijiao corresponding section, be provided with bolt hole and be inserted with 4 set bolts, regulate this bolt and can make length of spring compressed and make upper and lower clamping and sheet metal clamps in the same plane by this bolt hole.
A kind of anchor clamps of testing electrochemical properties of the utility model, its concrete operation is as described below:
(1), stressed spring is placed in the circular groove of lower clamp formwork, on lower clamp formwork, install and fix bolt.
(2), metal to be measured is positioned on the testing table, the lower surface square hole alignment of sheet metal workplace to be measured and upper clamp formwork is not tested the position at workplace and is stained with rubber cement or silica gel sheet, in case solution is revealed.
(3), upper clamp formwork is placed sample bench top, tight a bolt, make lower clamp formwork with sheet metal coincidence to be measured.
(4), electric pole is connected upper clamp formwork injected media solution, connection salt bridge with the lead of electrochemical workstation.
(5), carry out electro-chemical test.
(6), test after, unclamp upper clamp formwork, with the sheet metal to be measured lower surface square hole of test department bit alignment upper clamp formwork not, repeat above step.
The characteristics and the advantage of the utility model anchor clamps are as described below:
(1), omitted the process of traditional preparation sheet metal electrode, saved the test consumed time, and improved work efficiency.
(2), need not avoid causing back side plane out-of-flatness phenomenon at sheet metal back side soldering copper lead; Sheet metal to be measured when sample platform below has the fixing cord bar with last lower clamp formwork clamping in the utility model anchor clamps directly contacts, during test only need below lower clamp formwork, directly draw and connect lead and get final product.
(3), set up stressed spring in the utility model anchor clamps, more fitted tightly in the time of can making the upper and lower mould matched moulds, made sheet metal to be measured and upper and lower mould be in same plane.
(4), in the utility model anchor clamps, the workplace of sheet metal to be measured can repeat repeatedly multiple spot and test.
