Abstract
The present invention relates to a kind of clamp mechanism, more particularly to a kind of mechanical performance test fixture of composite.Including test specimen, bolt, horizontal clamping plate, mounting hole, it is characterized in that, also include vertical baffle and stop screw, the vertical baffle is arranged on the both sides between two horizontal clamping plates up and down, and one side is provided with blind hole, and opposite side is contacted with the test specimen, the lower plate of the horizontal clamping plate is U-shape structure, two sides are provided with screwed hole, and the lower plate that the stop screw passes through the horizontal clamping plate is the screwed hole of U-shape structure, and the other end is touched in the blind hole on the vertical baffle.The object of the invention is exactly by way of being clamped to coupon level and vertical direction, test specimen is not produced sliding under high temperature or experimental conditions, it is ensured that the accuracy of experiment material.
Description
Technical field
The present invention relates to a kind of clamp mechanism, more particularly to a kind of mechanical performance test fixture of composite.
Background technology
When carrying out creep or tension test, an improved clamping device has been designed to reliably clamp one end of composite material test piece.Fixture is required to use in the higher scope of big active force and temperature, during experiment, required for clamp applies to test specimen at high temperature, the tensile force of sliding will not be caused, so being produced without error, the phenomenon of suction occurs in some old-fashioned flat board clamps by contrast, the clamp of old-fashioned hydraulic-driven does not also allow to be placed in stove, and stove gradually transmits temperature to test specimen, and the increase in the rise and deformation in temperature can be produced to test specimen.
The content of the invention
In order to solve the above technical problems, the present invention is achieved by the following technical solutions：
A kind of mechanical performance test fixture of composite, including test specimen, bolt, horizontal clamping plate, mounting hole, it is characterized in that, also include vertical baffle and stop screw, the vertical baffle is arranged on the both sides between two horizontal clamping plates up and down, and one side is provided with blind hole, opposite side is contacted with the test specimen, the lower plate of the horizontal clamping plate is U-shape structure, two sides are provided with screwed hole, the lower plate that the stop screw passes through the horizontal clamping plate is the screwed hole of U-shape structure, and the other end is touched in the blind hole on the vertical baffle.
Further, the horizontal clamping plate top is a slab construction, and the uniform screw in both sides, one end is provided with the mounting hole, and bottom is a U-shape structure.
Further, the stop screw tightly locks the test specimen by the screwed hole on the horizontal clamping plate in vertical direction, and the test specimen is simultaneously by the pretightning force on horizontally and vertically direction.
The good effect that the present invention has is：
The object of the invention is exactly by way of being clamped to coupon level and vertical direction, test specimen is not produced sliding under high temperature or experimental conditions, it is ensured that the accuracy of experiment material.
Brief description of the drawings
The present invention is described in further detail for embodiment in below in conjunction with the accompanying drawings, but does not constitute any limitation of the invention.
Fig. 1 is a kind of mechanical performance test clamp structure schematic diagram of composite of the invention；
Fig. 2 is a kind of overlooking the structure diagram of the mechanical performance test fixture of composite of the present invention.
Wherein, 1, test specimen, 2, vertical baffle, 3, bolt, 4, horizontal clamping plate, 5, stop screw, 6, mounting hole.
Embodiment
In order that the object of the invention, technical scheme and advantage are more clearly understood, below in conjunction with drawings and Examples, the present invention will be described in further detail.It should be appreciated that the specific embodiments described herein are merely illustrative of the present invention, it is not intended to limit the present invention.
Fig. 1 is a kind of mechanical performance test clamp structure schematic diagram of composite of the invention.
A kind of mechanical performance test fixture of composite, including test specimen（1）, bolt（3）, horizontal clamping plate（4）, mounting hole（6）, it is characterised in that also including vertical baffle（2）And stop screw（5）, the vertical baffle（2）Installed in two horizontal clamping plates up and down（4）Between both sides, and one side is provided with blind hole, opposite side and the test specimen（1）Contact, the horizontal clamping plate（4）Lower plate be U-shape structure, two sides be provided with screwed hole, the stop screw（5）Pass through the horizontal clamping plate（4）Lower plate be U-shape structure screwed hole, the other end touches the vertical baffle（2）On blind hole in.
Wherein, horizontal clamping plate（4）Top is a slab construction, and the uniform screw in both sides, one end is provided with the mounting hole（6）, bottom is a U-shape structure.
Wherein, stop screw（5）Pass through the horizontal clamping plate（4）On screwed hole tightly lock the test specimen in vertical direction（1）, the test specimen（1）Simultaneously by the pretightning force on horizontally and vertically direction.
In use, first test specimen 1 is put on the bottom plate of horizontal clamping plate 4, then vertical baffle 2 is placed on to the both sides of test specimen 1, stop screw 5 is adjusted simultaneously, vertical baffle 2 is had certain pretightning force to test specimen 1, and adjust the center of test specimen 1, then put the top of horizontal clamping plate 4, bolt is loaded onto again, and bolt is locked, then stop screw 5 is locked, hole 6 is then fixedly mounted and arrives experiment porch, this device ensure that test specimen 1 does not produce sliding at high temperature, there is higher accuracy guarantee.
The foregoing is merely illustrative of the preferred embodiments of the present invention, is not intended to limit the invention, any modifications, equivalent substitutions and improvements made within the spirit and principles of the invention etc., should be included in the scope of the protection.
