Abstract
The invention relates to a tensile testing machine for a pultruded glass fiber reinforced plastic rod, which belongs to the technical field of the testing machine. An upper chuck block and a lower chuck block are respectively arranged in an upper fixture and a lower fixture through ball races, and a pair of jaw pressing plates with smooth opposite surfaces is respectively arranged between the upper chuck block and the lower chuck block. The tensile testing machine for the pultruded glass fiber reinforced plastic rod meets the requirements of GB/T13096.1 standard, the surface of the plastic rod can not be damaged, simultaneously a pretightening force can be provided, the specimen can be tightly clamped at the beginning of a test, the specimen can be tightly clamped without sliding when the tensile testing machine turns thinner under a pulling force in the tensile test process for the plastic rod, and the specimen is uneasy to crack.
Description
Technical field
The present invention relates to the testing machine technical field, particularly use 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.
Summary of the invention
The object of the invention 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 invention, 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 present invention 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 of the present invention is supported in the upper and lower clamp body by spring.
In addition, the present invention also opens bolt hole respectively in upper and lower clamp body, support corresponding spring by bolt respectively in upper and lower clamp body.
The present invention 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.
