Embodiment Construction
[0010] The tensile fixture of the electronic universal testing machine includes a fixture joint 1 connected with a movable beam or a base. The fixture joint 1 is connected with a fixture base 2. The fixture base 2 is fixedly installed with a semicircular fixed clamp block 4 through a number of screws 3, and the fixture base 2 A semicircular sliding clamp block 5 is provided to cooperate with the semicircular fixed clamp block 4, a pin shaft 6 is provided on the clamp base 2, and a sliding groove is provided on the semicircular sliding clamp block 5 to sleeve the pin shaft 6.
[0011] The semicircular sliding clamp block 5 of the present invention is located between the semicircular fixed clamp block 4 and the clamp joint 1, and the contact surface between the semicircular sliding clamp block 5 and the semicircular fixed clamp block 4 is sawtooth.
[0012] When installing sample 7, move the semicircular sliding clamp block 5 along the pin axis to separate from the semicircular fixed ...

The invention relates to a stretching clamp of an electronic universal tester. The stretching clamp comprises clamp joints connected with movable beams or bases, wherein each clamp joint is connected with a clamp holder; a semicircular fixed clamp splice is fixedly mounted on each clamp holder through a plurality of screws; a semicircular sliding clamp splice is also arranged on each clamp holder and matched with the semicircular fixed clamp splice; a pin shaft is arranged on each clamp holder; a chute is formed in each semicircular sliding clamp splice and sleeved with the pin shaft. The stretching clamp has a simple structure, is safe and reliable, and can be used conveniently and quickly; and after a sample is wound around the clamp and stressed, the clamp can automatically clamp to reflect the true bearing value of the sample.
Description
Technical field [0001] The invention relates to a tensile clamp of an electronic universal testing machine. Background technique [0002] The electronic universal testing machine controls the rotation of the servo motor through the controller and the speed control system. After the deceleration system is decelerated, the moving beam is driven up and down by the precision screw pair to complete the tensile, compression, bending, and shearing of the sample. Performance test. The electronic universal testing machine has the advantages of no pollution, low noise, high efficiency, etc., and has a very broad application prospect in the mechanical performance test of metals, non-metals, composite materials and products. [0003] The structure of the tensile fixture of the existing electronic universal testing machine is basically a claw structure. The sample is clamped during the test. However, when the clamping force of the fixture is insufficient during the ascent of the moving beam, t...
