Description
Technical Field
The utility model relates to the technical field of test target bases, in particular to an adjustable test target base support of a Hopkinson system.
Background
The Hopkinson pressure bar technical system is a test device for researching dynamic mechanical properties of materials under high strain rate loading, target bases in a system test target chamber have the requirements of adjusting and recalibrating the target bases along with the impact effect of system tests and different diameters of selected samples, wherein a test target base support device is an adjusting device for ensuring the coincidence of the axial central line of the test samples in the Hopkinson pressure bar test system target chamber and the axial central line of a system emission pipe orifice, and the problem that the adjustment reliability is influenced due to unbalanced support adjustment of a support plate in the existing support device structure is solved.
Disclosure of Invention
In order to overcome the defects of the prior art, the utility model aims to provide an adjustable test target base support of a Hopkinson system.
In order to achieve the purpose, the utility model adopts the technical scheme that:
an adjustable test target base support of a Hopkinson system, comprising: the box, box opening upper end sets up the symmetry bracket, and the symmetry bracket comprises first bracket and second bracket, and the crossing side of first bracket and second bracket is fixed at the central point of box opening upper end both ends through the articulated shaft, and first bracket and second bracket opposite side are connected with lift supports and are constituteed.
The utility model provides a hopkinson system adjustment formula test target base support, lifting support frame is connected with telescoping device by the support frame and forms, and the support frame is U type structure, both ends respectively with the slide bar that sets up on the first bracket and the slide bar sliding connection that sets up on the second bracket on the U type structure support frame.
Due to the adoption of the technical scheme, the utility model has the following beneficial effects:
according to the utility model, the U-shaped structure supporting frame is pushed to rise through the work of the telescopic device in the box body, and the two ends of the U-shaped structure supporting frame respectively push the sliding rod on the first bracket and the sliding rod on the second bracket to slide, so that a proper V-shaped included angle is achieved, and the adjustability and the test application of the test target base of the system target chamber are realized. The utility model has simple structure and convenient installation, adjustment and assembly, reduces the adjustment efficiency of the target base for testing in the target chamber, solves the problems of complexity and replacement process of the whole adjustment of the base of the test target base, and can meet the experimental requirements of the target chamber of the conventional system in the testing effect.
Drawings
Fig. 1 is a schematic structural diagram of a Hopkinson system adjustable test target base support.
FIG. 2 is a schematic view of the lifting structure of the adjustable test target base support.
In the figure: the box body 1, a support frame 2, a telescopic device 3, a first bracket 4, a slide bar 4.1/4.2, a second bracket 5, a slide bar 5.1 and a hinge shaft 6.
Detailed Description
As shown in fig. 1 and 2, an adjustable test target base support of a hopkinson system comprises: the box 1, 1 opening upper end of box sets up the symmetry bracket, and the symmetry bracket comprises first bracket 4 and second bracket 5, and the crossing side of first bracket 4 and second bracket passes through articulated shaft 6 to be fixed at the central point of 1 opening of box upper end, and first bracket 4 and second bracket opposite side are connected with lift support frame and are constituteed.
The lifting support frame is formed by connecting a support frame 2 and a telescopic device 3, the support frame 2 is of a U-shaped structure, and two ends of the support frame 2 of the U-shaped structure are respectively in sliding connection with a sliding rod 4.1 arranged on a first bracket 4 and a sliding rod 5.1 arranged on a second bracket 5. The telescopic device 3 is a hydraulic cylinder.
During the use, promote U type structure support frame 2 through the work of telescoping device 3 in the box 1 and rise, both ends promote slide bar 4.1 on the first bracket 4 and the slide bar 5.1 on the second bracket 5 respectively on U type structure support frame 2 and slide, reach suitable V type contained angle, for example 120 degrees, 90 degrees, 60 degrees.
And then the auxiliary supporting plates which are screwed in by using the bolt group array after the rectangular array group thread through holes are symmetrically arranged on the two supporting plates of the assembly, so that the adjustability and the test application of the test target base of the system target chamber are realized.
After use, the expansion device 3 drives the first bracket 4 and the second bracket 5 to descend to the end face of the opening of the box body 1 through the support frame 2 with the U-shaped structure.
