The quality accident of material matrix.There is presently no the determinator of special evaluation water-repellent paint flexible life.
Summary of the invention
The purpose of this utility model provides one to be used for for the weak point in the presence of above-mentioned prior art just
Evaluate the determinator of water-repellent paint flexible life.Determinator of the present utility model can preferably solve existing waterproof painting
Material can not simulate actually used in bear the test difficult problem of the fatigue behaviour after dynamic loading, it is achieved that water-repellent paint fatigue life
Completely, accurately, conveniently, safely, measure rapidly.
The purpose of this utility model can be realized by following technique measures:
Determinator for evaluating water-repellent paint flexible life of the present utility model includes lower connector, with vertically
The mode downwardly extended is arranged on the lower connecting rod of lower connector center position bottom surface, is separately mounted to lower connector two ends
The left and right clamp system being made up of upper movable block and lower fixed block, is clamped in the coating vehicles between described left and right clamp system
Steel plate, by latch, upper connector to be arranged on the perpendicular of coating vehicles steel plate middle position with lower connecting rod coaxial line mode
Straight upwardly extending upper connecting rod.
This utility model end that cooperates of movable block and lower fixed block on described is separately installed with and held painting
The bearing matched in material carrier steel plate two sides.Described upper movable block is arranged on lower connector by set screw and lock screw
Upper end, described lower fixed block by fixed screw to be arranged on the lower end of lower connector by the way of relative with upper movable block.When
During coating vehicles steel plate stress, by the slip fine setting effect of two pairs of bearings, enable coating vehicles steel plate freely the most curved
Bent deformation, is unlikely to steel plate stuck in fixture, it is ensured that acting on by stable alternating bending stress on coating.Coating vehicles
Steel plate is put between the sliding bar of bearing, then tightens the set screw at two ends, then the lock tightened on left and right two ends in movable block
Tight screw, prevents set screw during test from occurring to loosen, the accuracy of impact test.
Operation principle of the present utility model is as follows:
First water-repellent paint is sprayed on the positive and negative on coating vehicles steel plate before test, then coating vehicles steel plate is contained in
On flexural fatigue determinator, then it is connected with fatigue machine by upper and lower connecting rod, it is achieved water-repellent paint is born the most curved
The assessment of the destruction after bent times of fatigue.
The beneficial effects of the utility model are as follows:
This utility model solve existing can not simulate actually used in bear the test difficult problem of the fatigue behaviour after dynamic loading,
Water-repellent paint sample is sprayed on coating vehicles steel plate, fatigue machine connecting tooling device is loaded and realize indirect to sample
Load.The axial force that upper and lower connecting rod carrying fatigue machine is main, is realized connection by upper and lower connector and assembly thereof simultaneously
The axial force of bar transmission is converted to three-point bending stress, makes to receive between the coating of coating vehicles surface of steel plate upper and lower alternation
Bending load, the alternate stress that the centre that coating vehicles steel plate is coated is subject to is maximum, for main assessment position.
Utilize this utility model to measure, assess coating and bear alternating bending stress, measurement result accurately, reliable, operation
Conveniently, safely, manufacturer, user and testing agency for water-repellent paint provide the foundation manufacturing, using and detect, it is to avoid anti-
Water paint causes leakage accident and quality accident because of cracking after life-time service, destruction.

Detailed description of the invention
This utility model is further described below with reference to embodiment (accompanying drawing):
As it is shown in figure 1, the determinator for evaluating water-repellent paint flexible life of the present utility model includes lower company
Junctor 11, is arranged on the lower connecting rod 12 of lower connector center position bottom surface in the way of extending straight down, is respectively mounted
Lower connector two ends by the left and right clamp system that forms of movable block 6 and lower fixed block 9, be clamped in described left and right clamping
Coating vehicles steel plate 10 between mechanism, by latch 3, upper connector 2 to be arranged on painting with lower connecting rod 12 coaxial line mode
The upper connecting rod 1 extended straight up of material carrier steel plate middle position.
This utility model end that cooperates of movable block 6 and lower fixed block 9 on described is separately installed with held
The bearing 7 matched in coating vehicles steel plate two sides.Described upper movable block 6 is arranged on down by set screw 4 and lock screw 5
The upper end of connector, described lower fixed block 9 is arranged on lower connector by fixed screw 8 by the way of relative with upper movable block 6
Lower end.When coating vehicles steel plate 10 stress, by the slip fine setting effect of two pairs of bearings 7, make coating vehicles steel plate 10 energy
Enough flexural deformation up and down freely, is unlikely to steel plate stuck in fixture, it is ensured that by stable alternating bending stress on coating
Effect.Coating vehicles steel plate 10 is put between the sliding bar of bearing 7, then tightens the set screw 4 at two ends, then tighten a left side,
