Abstract
The utility model relates to a testing machine for pulling-squeezing glass fiber and enhancing plastic bar stretching, which belongs to the technical field of testing machines. An upper collet and a lower collet are respectively arranged in an upper clamping apparatus and a lower clamping apparatus through rollaway nests, and a pair of jaw keep plates with the opposite sides being grain sides is respectively arranged between the upper collet and the lower collet. The testing machine special for test of pulling-squeezing glass fiber and enhancing plastic bar stretching accords to the requirement of standard GB/T13096.1, cannot damage the surface of the plastic bar for clamping, and can apply pretightening force simultaneously, tightly clamp a sample at the beginning of a test, and tightly clamp the sample without skidding during the plastic bar stretching test because of becoming thin after being pulled; in addition, the sample is not easy to crack.
Description
Technical field
The utility model relates to the testing machine technical field, particularly uses the test apparatus that extruding fiberglass-reinforced plastic lever is carried out tension test.
Background technology
Extruding fiberglass-reinforced plastic lever is a kind of proprietary material that is formed by the glass fibre extruding, and this material smooth in appearance ftractures easily, tests the tensile property of this material before with common puller system, owing to the damage of material retained part influences test accuracy.
The utility model content
The utility model purpose is to design a kind of suitable extruding fiberglass-reinforced plastic lever tension test usefulness, the tensile machine for stretching and extruding fiberglass-reinforced plastic lever that sample is not easy to crack, test accuracy is high.
In base of the present utility model, be furnished with servomotor, the horizontal middle base of fixed and arranged on the base, the outside in horizontal middle base fixedly installs vertical aiding support bar, upper end fixed lateral back timber at vertical aiding support bar, between back timber and middle base, arrange that by bearing an opposition is to ball screw, difference attaching nut on two ball screws, a fixedly connected crossbeam between two nuts; The lower end of described two ball screws is the big synchronous pulley of coaxial connection respectively, and two big synchronous pulleys and servomotor are in transmission connection; Connect the lower clamp seat on middle base, connect the lower clamp body on the lower clamp seat, arrange the lower chuck piece in the lower clamp body, described lower jaw pressing plate is supported on down on the mandrel, and following mandrel bottom is set in the lower clamp body, and the bottom connects the lower chuck set nut; Connecting clamping fixture seat on the crossbeam by sensor, connect on the last clamping fixture seat inboard be provided with the inclined-plane on clamp body, layout upper grip piece in last clamp body, described upper grip piece is supported on the mandrel, the middle part of last mandrel is set in the clamp body, and top connects the upper grip set nut; It is characterized in that described upper and lower chuck piece is arranged in the upper and lower clamp body by raceway respectively; Arrange respectively that between upper and lower chuck piece opposite face is a pair of jaw pressing plate of light face.
The utility model is the special-purpose testing machine of extruding fiberglass-reinforced plastic lever tension test, meet the GB/T13096.1 standard-required, on its principal feature is, the lower jaw pressing plate does not have internal tooth, can not crush the plastic bar surface, simultaneously can apply pretightning force, when beginning to test, can clamp sample, and on the inclined-plane between chuck piece and the clamp body, be equipped with raceway, be rolling friction so become the sliding friction of common puller system between the two, thereby in plastic bar tension test process, sample can tightly be clamped owing to attenuated by pulling force and non-slip, sample is not easy to crack, because the jaw pressing plate can be convenient for changing according to various sample, has improved test efficiency and precision.
Raceway described in the utility model is supported in the upper and lower clamp body by spring.
In addition, the utility model is also opened bolt hole respectively in upper and lower clamp body, support corresponding spring by bolt respectively in upper and lower clamp body.
The utility model also is provided with high strength rigidity liner plate respectively between raceway and upper and lower clamp body, detect test to improve high-precision maximum pull.
