Description
Technical field
The utility model relates to a kind of percent thermal shrinkage proving installation, can use simultaneously with pyrocondensation stress test mechanism.
Background technology
Thermal contraction performance comprises pyrocondensation stress and percent thermal shrinkage, needs to measure power and the displacement that produces when sample receives thermal shrinkage.The detection of past pyrocondensation stress and percent thermal shrinkage is carried out respectively, not only need use many checkout equipments, and test efficiency is low, automaticity is low, also can't analysis-by-synthesis pyrocondensation stress and percent thermal shrinkage between relation.To two tests be combined, must realize the robotization of test.
The robotization detection difficulty that realizes percent thermal shrinkage is bigger; Mainly contain following 2 reasons: contact method detects weight or the friction force that percent thermal shrinkage need overcome displacement transducer self; And weight or friction force more can't be ignored with respect to sample self pyrocondensation stress, therefore the accuracy of meeting disturbed test data; The noncontact method detects the influence receive temperature, displacement and sample self property (fast like contraction speed, shrinkage factor is high, shrinkage direction mutability etc.) and is difficult for realizing, and the noncontact method to detect cost expensive, be unfavorable for the popularization and application of checkout equipment.
The utility model content
The utility model is the deficiency that overcomes above-mentioned prior art, and a kind of reliable structure that has is provided, and is easy to use, can carry out the percent thermal shrinkage proving installation that the sample percent thermal shrinkage detects exactly.

Said test panel top is provided with a position-arresting disk, position-arresting disk and test panel axially parallel, and connecting link places between position-arresting disk and the test panel.
The percent thermal shrinkage proving installation of the utility model comprises a connecting link, and connecting link places in the guiding mechanism and with the contraction measurement mechanism and is connected, and any end of connecting link all can be connected with sample.Shrink measurement mechanism and comprise a test panel that is installed on the bracing frame, test panel is connected with a rotary encoder; Connecting link places on the circumference of test panel, makes that connecting link and test panel circumference are tangent, and connecting link and test panel are axially perpendicular; Test panel rotates with moving synchronously of connecting link.Test panel and rotary encoder are fixed together, and rotary encoder also is fixed on the bracing frame.The test panel top is provided with a position-arresting disk, and position-arresting disk and test panel axially parallel, connecting link place between position-arresting disk and the test panel, and the distance between position-arresting disk and the test panel center is position-arresting disk radius, test panel radius and connecting link diameter three sum.Connecting link is can be high temperature resistant, rigidity is big, the object of light weight.Should have suitable friction force between connecting link and the test panel, rely on this friction force can realize that test panel rotates with moving synchronously of connecting link.But the friction force between connecting link and the test panel should be much smaller than the pyrocondensation stress of sample, and should ignore with respect to this friction force of pyrocondensation stress of sample.Friction force between connecting link and position-arresting disk and the guiding mechanism also should be little of ignoring.The test before with connecting link place in the guiding mechanism and place position-arresting disk and test panel between, position-arresting disk and test panel all are fixed on the bracing frame, an end and sample one end with connecting link links together then.Test panel rotates with moving synchronously of connecting link, and test panel also is fixed together with the rotary encoder that is fixed on the bracing frame simultaneously.When sample receives thermal shrinkage; Connecting link will move along with the contraction of sample; Driving test panel rotates synchronously; And the rotary encoder that links to each other with test panel also can together rotate, and the rectilinear motion of sample has just changed into rotatablely moving of rotary encoder like this, can record the displacement (calculating can get the percent thermal shrinkage of sample) of sample through rotary encoder output according to the rotary coder shaft rotation and the relation of output umber of pulse.
The advantage of the utility model is:
1. measure accurately, shrink the interference that test does not receive the sample shrinkage direction, reflect that truly sample shrinks displacement.
2. clear principle, simple in structure, reliable and stable, cheap.
3. can use simultaneously with pyrocondensation stress test mechanism, show the relation of pyrocondensation stress and percent thermal shrinkage in real time.
