Abstract
The utility model relates to a novel flexible pull head of a universal testing machine. The novel flexible pull head consists of a fixed pull head, a universal joint and clamping apparatuses, wherein the fixed pull head is fixedly arranged on a rack, the universal joint and the fixed pull head are in threaded connection, and the clamping apparatuses and the universal joint are in threaded connection. The flexible pull head is in use through vertical corresponding combination, in testing, a sample is adhered on the upper and lower clamping apparatuses, and then, tension tests are carried out. The universal joint is additionally arranged on the fixed pull head of the testing machine, so as to automatically compensate pressure from each side and reduce test errors effectively, and therefore, the test accuracy can be ensured.
Description
Technical field
The utility model relates to produces experiment apparatus technical field, specifically is the flexible pull head of novel universal testing machine.
Background technology
When using universal testing machine to measure the wood-based plate mechanical performance index; because what use on the omnipotent machine is fixing pull head; rusty stain or glue are attached to the first-class factor affecting of jig on component wear, the pull head; or the deviation of the location of packing into; make pull head and jig a small amount of inclination can occur; when this kind situation occurs; will cause the sample discontinuity; the destruction of sample is often at first from one side to the process of tearing of another side; resultant detected value can be less than actual value, and this has just caused the inaccuracy that detects.
Summary of the invention
The utility model overcomes defective and the random factor of fixedly pull head existence, to the influence of detection accuracy, provides a kind of universal testing machine flexible pull head.
The technical solution of the utility model is: the flexible pull head of novel universal testing machine, formed by fixedly pull head, universal joint, jig, and wherein, fixture splice is fixed on the frame, and universal joint is threaded with fixture splice, and jig is threaded with universal joint.Flexible joint is used in combination for correspondence up and down, during experiment, sample is bonded at up and down on the jig, begins to carry out pulling experiment.
The utility model is taked to install universal joint additional at the fixed pull head of testing machine, can compensate each side's pressure automatically, effectively reduces test error, thereby has guaranteed the accuracy that detects.
Description of drawings
Accompanying drawing is the utility model structural representation.
Wherein: 1, fixedly pull head 2, universal joint 3, jig
Embodiment
The utility model is described in further detail below in conjunction with accompanying drawing.
The flexible pull head of novel universal testing machine as shown in the figure, is made up of fixedly pull head 1, universal joint 2, jig 3, and wherein, fixture splice 1 is fixed on the frame, and universal joint 2 is threaded with fixture splice 1, and jig 3 is threaded with universal joint 2.Flexible joint is used in combination for correspondence up and down, during experiment, sample is bonded at up and down on the jig 3, begins to carry out pulling experiment.
