Abstract
The invention discloses a clamp for a tension test of a glass reinforcement. The clamp is used for fixing the glass reinforcement on tension equipment, and comprises two clamping components, and two fastening belts corresponding to the two clamping components. Each clamping component is provided with a through hole and comprises two clamping parts for dividing the corresponding clamping component into two parts, the two clamping parts are symmetrically arranged relative to the hole axis of the through hole, and the through hole is internally provided with an internal thread screwed with an external thread of the glass reinforcement. A net-shaped accommodating groove is formed in the outer side of each clamping part, and each fastening belt is used for fixing the corresponding clamping component on the glass reinforcement screwed with the clamping component by winding in the net-shaped accommodating groove. The clamp greatly guarantees that the glass reinforcement and the clamp are on the same axis, so that the glass reinforcement in the tension test does not deviate from the center line of the stress, the test result is not affected, and the clamp can be repeatedly used.
Description
Technical field
The present invention relates to a kind of fixture of strength test, particularly a kind of fixture of glass muscle material strength test.
Background technology
The finished product of glass muscle material is the cylinder of threaded, its strength test is with being that two perforated pipe shape fixtures are enclosed within the two ends of glass muscle material respectively, and make it engage firmly at the cover junction injecting glue of these two parts, do experiment to clamp two tubuloses by experimental facilities and carry out tensile test, because glass muscle material is enclosed within tubular fixture, the right alignment of muscle material and tubular fixture can not be ensured, affect tensile test result, in addition, at the knot face injecting glue of muscle material and tubular fixture, glue in tubular fixture after test can not be removed, can not reuse, and after injecting glue, be not easy to parch, need to wait gelling solid, lose time, affect test efficiency.
Summary of the invention
For the deficiency of existing scheme, the present invention proposes a kind of fixture of glass muscle material strength test, can ensure that glass muscle material is coaxial with this fixture, improve the accuracy of glass muscle material tensile test, and fixture can reuse.
The present invention is achieved in that a kind of fixture of glass muscle material strength test, and it is for will for being fixed on tension equipment by glass muscle material, and described fixture comprises two clamp assemblies, two restraint zones corresponding with described two clamp assemblies; Each clamp assemblies offers through hole, each clamp assemblies comprises two clamping parts respective clamp assembly being divided into two halves, described two clamping parts are symmetrical arranged with the axially bored line of described through hole, are provided with the internal thread be screwed with the external thread of described glass muscle material in described through hole; The arranged outside of each clamping part has netted accepting groove, and every bar restraint zone is by being wound in netted accepting groove on the glass muscle material that is fixed on by respective clamp assembly and screws togather with this clamp assemblies.
As the further improvement of such scheme, each clamp assemblies is cylindrical shape.
The present invention is in advantage, the external thread of the internal thread in the through hole of clamp assemblies and glass muscle material screws togather in spiral, glass muscle material and this fixture can be ensured greatly on the same axis, make the glass muscle material in tensile test can not depart from center of effort's line, affect tensile test result; Adopt the threaded engagement with glass muscle material, do not need to bond with glue, make fixture no longer single use, improve the utilization rate of fixture, reduce the loss of glass muscle material and fixture.
Accompanying drawing explanation
The schematic diagram that the fixture of the coloured glaze muscle material strength test that Fig. 1 provides for better embodiment of the present invention coordinates with glass muscle material.
Fig. 2 is the structural representation of fixture in Fig. 1.
Embodiment
In order to make object of the present invention, technical scheme and advantage clearly understand, below in conjunction with drawings and Examples, the present invention is further elaborated.Should be appreciated that specific embodiment described herein only in order to explain the present invention, be not intended to limit the present invention.
Refer to Fig. 1 and Fig. 2, the fixture of glass muscle material strength test is for will for being fixed on tension equipment by glass muscle material 2.Described fixture comprises two clamp assemblies 3, two the restraint zone (not shown) corresponding with described two clamp assemblies 3.
Each clamp assemblies 3 offers through hole 4, and each clamp assemblies 3 comprises two clamping parts 5 respective clamp assembly being divided into two halves.Described two clamping parts 5 are symmetrical arranged with the axially bored line of described through hole 4, are provided with the internal thread be screwed with the external thread of described glass muscle material 2 in described through hole 4.Each clamp assemblies 3 can be cylindrical shape.
The arranged outside of each clamping part 5 has netted accepting groove 6, and every bar restraint zone is by being wound in netted accepting groove 6 on the glass muscle material 2 that is fixed on by respective clamp assembly 3 and screws togather with this clamp assemblies 3.The vestige direction of accepting groove 6 and the central axis of clamp assemblies 3.Accepting groove 6 makes clamp assemblies 3 large with the skin-friction force of measurer for pulling force and clamp assemblies 3, can well catch clamp assemblies 3.
The material of clamp assemblies 3 can for being harder material, can bear tension test machine to the surface pressing of clamp assemblies 3 and internal thread not easy-to-draw bad, be preferably steel, to carry reusing of clamp assemblies 3.
During tension test, two same round clamp assemblies 3 are located at respectively the two ends of glass muscle material 2, the catching plate then two same clamp assemblies 3 being placed on tension test machine carries out tensile test.
The foregoing is only preferred embodiment of the present invention, not in order to limit the present invention, all any amendments done within the spirit and principles in the present invention, equivalent replacement and improvement etc., all should be included within protection scope of the present invention.
Claims (2)
1. a fixture for glass muscle material strength test, it is for for glass muscle material is fixed on tension equipment, is characterized in that: described fixture comprises two clamp assemblies, two restraint zones corresponding with described two clamp assemblies; Each clamp assemblies offers through hole, each clamp assemblies comprises two clamping parts respective clamp assembly being divided into two halves, described two clamping parts are symmetrical arranged with the axially bored line of described through hole, are provided with the internal thread be screwed with the external thread of described glass muscle material in described through hole; The arranged outside of each clamping part has netted accepting groove, and every bar restraint zone is by being wound in netted accepting groove on the glass muscle material that is fixed on by respective clamp assembly and screws togather with this clamp assemblies.
2. the fixture of glass muscle material strength test as claimed in claim 1, is characterized in that: each clamp assemblies is cylindrical shape.
