Description
Technical field
The utility model relates to employed anchor clamps in a kind of measuring technique, particularly a kind of anchor clamps of nonmetal tension test.
Background technology
Along with the widespread use of various nonmetallic materials in space flight, the energy, field such as electric, the mechanical property of research nonmetallic materials just seems extremely important.
Material mechanical performance test is carried out being furnished with on the cryomechanics test macro system controlled by computer electronics universal testing machine of normal temperature mechanical meaurement system and independent development, and data are connected on the computing machine control by the high-sensitive instrument of high precision and gather.Stretching clamp then is an one of critical component of measuring the tensile mechanical properties of material, in the process of test, the two ends of test specimen should be fixed on the anchor clamps, and anchor clamps are fixedlyed connected with cupping machine, testing machine is by the anchor clamps tensile sample, concrete test condition reference standard is carried out, and the shape and size of sample meet GB or ASTM standard usually.Mechanical properties such as the pulling strengrth of final acquisition sample, elastic modulus, extensibility.
At present both at home and abroad the tensile test fixture that provides of sample machine factory adopts the anchor clamps of spring auto-locking suspension usually, its mainly the friction force that produces of the sawtooth by self-lock force and clamping surface the both ends of sample are stepped up, carry out tension test thereby be connected with testing machine.The shortcoming of this anchor clamps is: anchor clamps are difficult for installing at low temperatures, and sample is had certain destructiveness; The general complex structure of these anchor clamps, volume are big, the expense height, and poor with the sample regulating power, anchor clamps are the fixation test sample effectively.
Summary of the invention
The purpose of this utility model is to overcome the shortcoming of existing anchor clamps, provides a kind of stretching clamp according to the architectural feature of standard sample, effectively reduces cost, and can regulate according to the feature of sample.
To achieve these goals, the utility model provides a kind of nonmetal tensile test fixture, is used for the nonmetallic materials stretching mechanical property testing; These anchor clamps comprise main body, jig main body, clamp body; Body shape is a left side notched square type cell body, and there are two counter sinks the main body front, and there are two top wire holes the main body back, and the main body side has an openend, so that in the process of test standard sample is embedded in this zone; In the notched square type cell body of jig main body and the clamp body left side in main body, height is consistent with main body, and width is consistent with notched square type zone, the left side, so that jig main body and clamp body take out from main body where necessary; Two counter sinks are arranged on the clamp body, two threaded holes are arranged on the jig main body, indentation is all arranged on clamp body and the jig main body, be used for evenly clamping sample.Link to each other with main body with screw by jackscrew; The jig main body upper end is provided with the coupling shaft that is connected with cupping machine, and coupling shaft is provided with a through hole, and the hole is radially vertical with coupling shaft.Main body inner wall is a chamfering or circular-arc, and clamp body and anchor clamps master edge are chamfering or circular-arc.
Following advantage is arranged specifically:
The beneficial effects of the utility model are: compare with the anchor clamps of existing use both at home and abroad, reduced spring auto lock part, structure is simpler, thereby volume reduces, and weight is low weight, the structure clamping is more convenient, only need tighten with spanner, just assembly and disassembly easily accomplish effectively to clamp sample, anti-slide mark on clamp body and the jig main body can prevent effectively that sample from skidding, and steps up sample uniformly.Clamp body in the anchor clamps and jig main body, its processing and fabricating simply can be adjusted width according to sample, has saved cost greatly.Be applicable to the Mechanics Performance Testing of nonmetallic materials such as various macromolecular materials, compound substance, have higher use value.

Embodiment
These anchor clamps comprise main body 1, jig main body 5, clamp body 7 among the embodiment; Main body 1 is shaped as the left side notched square type cell body, and there are two counter sinks 2 main body 1 front, and there are two top wire holes 8 main body 1 back, and main body 1 side has an openend 6; In the notched square type of the jig main body 5 and the left side of clamp body 7 in main body 1 cell body, height is consistent with main body 1, width is consistent with notched square type zone, the left side, two counter sinks 10 are arranged on the clamp body 7, two threaded holes 4 are arranged on the jig main body 5, on clamp body 7 and the jig main body 5 indentation is arranged all, link to each other with main body 1 with screw by jackscrew; Jig main body 5 upper ends are provided with the coupling shaft 3 that is connected with cupping machine, and coupling shaft 3 is provided with a through hole 9.
Principle of work:
With reference to accompanying drawing 1-2, at first clamp body and jig main body are placed in the notched square type zone, the main body left side, the counter sink that passes on the main body with screw is connected with threaded hole on the jig main body, and tighten, pass the main body threaded hole with jackscrew and withstand counter sink on the clamp body, this moment is gapped between jig main body and clamp body.Secondly, the coupling shaft on the jig main body directly is connected with register pin by through hole with testing machine, sample is put between clamp body and the jig main body from the openend of main body side, tighten top wire hole with spanner and clamp sample, can test.
The results showed that stretching clamp volume of the present utility model is little, in light weight, simple in structure, convenient mounting and clamping has effectively overcome the phenomenon of skidding, and has saved cost greatly.The utility model is applicable to the Mechanics Performance Testing of nonmetallic materials such as various macromolecular materials, compound substance, and to the sample not damaged, fracture location all in the gauge length scope of standard code, can clamp sample uniformly, has higher use value.
