And said upward transverse frame plate and lower cross frame plate middle part laterally all are shaped on and the homoaxial chute of frame plate, and it is identical with last pull head upper end and following pull head bottom shape that this chute is separated cross sectional shape, and the pull head end embeds in the chute.
And; Said pulling experiment machine also comprises industrial computer; Industrial computer comprises data acquisition module, data disaply moudle and data processing module, and data acquisition module connects industrial camera; Data disaply moudle connects display and/or printer, and data processing module connects and is used to drive the tension tester motor reducer group of pull head up and down.
And the said transverse frame plate of going up is connected with column through two slide blocks respectively with the lower cross frame plate.
And, draw anchor clamps or drop-down anchor clamps that pulling force sensor all is installed on said, and anchor clamps are according to the fit shapes of different cables or other wire determinands adjustment retaining parts and determinand.
And pull head, following pull head are connected with the motor reducer group respectively on each.
The utility model advantage and good effect are:
1, this tension tester is through camera support mounting industrial camera; Satisfied the test overall process through camera system with the dynamic tensile process reaction on computer screen, can capture a certain node change procedure on the sample at any time, make this tension tester running program easy; Can realize man-machine conversation; The contents of a project of needs are directly imported in screen, very convenient through computer system, obtain required data fast
2, this tension tester is saved test period and is alleviated operation labour intensity; 5 times process of the test becomes process of the test 1 time; 1 test can be provided the test figure of 5 samples simultaneously; Can accurately calculate the tensile strength and breaking elongation technical indicator of material of sample through computer system after, provide the check raw readings by print system, the inspection record form can be worked out voluntarily.
3, this tension tester is through changing the pulling force checkout equipment that stretching clamp also can be used as other materials; For example may be used on the material that inertia such as nonferrous materials, plastic material change; So the utility model both can be used as stand-alone application on existing tension tester; Can repack the test type into introducing this test puller system on the existing structure basis of other type again, application market is wide.
