Description
Technical field
The utility model relates to a kind of stress test platform, is specifically related to a kind of carrying jig stress test platform.
Background technology
In the experiment of indentation method, by the in advance to be measured point of ball pressure head in its experiment material adds certain load, make its surface in experiment material produce certain plastic yield, the shape impression of spherical crown can be formed, corresponding stress field will be produced around impression.Will cause in the surrounding of its impression the increment producing fixed amount and produce because of strain in the middle of the process producing stress field, the diameter D of the formation of stress field and the generation of its strain increment and steel ball, load p, this test point and the distance of load application point and the material property of test specimen itself relevant, and closely related with the size of unrelieved stress.So when the steel ball as pressure head is when its radius, interval, magnitude of load are fixed values, unrelieved stress can be created and have associating of demarcation with the increment produced because of strain, in the middle of the unrelieved stress process of the test of reality, obtaining for the unrelieved stress in experiment material certainly of the increment that the process that can cause through its indentation method produces because of strain, and test specimen can be made to be subject to correlationship etc. that horizontal tension and compression stress is used for detecting unrelieved stress and horizontal tension and compression.But existing stress test platform is higher to the shape need of workpiece when testing, need before test to process in advance, and it is comparatively large to take up room, and is unfavorable for effective utilization in space.
Utility model content
The purpose of this utility model is to provide a kind of compact conformation, requires lower and without the need to carrying out processing in advance carrying jig stress test platform to workpiece shapes.
For achieving the above object, the utility model provides following technical scheme:
A kind of carrying jig stress test platform, comprise frame, the mount pad be connected with frame by guide pole is provided with below frame, mount pad internal fixtion has two horizontal positioned and all outside horizontal hydraulic cylinder is held in effect, two horizontal hydraulic cylinder piston rod ends are connected with fixed cap, and be individually fixed on two clamping seats by fixed cap and bolt, clamping seats bottom is provided with through hole in guide pole position, clamping seats is connected on guide pole by through hole, two clamping seats tops have been bolted square clamping plate, square clamping plate are connected on crossbeam by chute, the platform for place work piece is provided with in the middle part of crossbeam, for being connected to the column in frame above platform, column lower end is provided with vertically to be placed and acts on the downward vertical hydraulic cylinder of end, vertical hydraulic cylinder piston rod end has been bolted pressure head web member, pressure head web member has been bolted pressure head.
As the further improvement of above-mentioned technology, described pressure head effect end is hemispherical.
Compared with prior art, the beneficial effects of the utility model are: only need ensure that workpiece can be able to be tested by clamping on fixture, require lower to workpiece shapes, without the need to processing in advance, and hydraulic cylinder occupy middle, save the space in horizontal direction, make test platform structure compacter.
Accompanying drawing explanation
Fig. 1 is the structural representation of carrying jig stress test platform.
Fig. 2 is the side sectional view of carrying jig stress test platform.
In figure: 1-frame, 2-guide pole, 3-fixed cap, 4-horizontal hydraulic cylinder, 5-mount pad, 6-clamping seats, the square clamping plate of 7-, 8-pressure head web member, 9-vertical hydraulic cylinder, 10-column.
Embodiment
Be described in more detail below in conjunction with the technical scheme of embodiment to this patent.
A kind of carrying jig stress test platform, comprise a kind of stress test platform of carrying jig, comprise frame 1, the mount pad 5 be connected with frame 1 by guide pole 2 is provided with below frame 1, mount pad 5 internal fixtion has two horizontal positioned and all outside horizontal hydraulic cylinder 4 is held in effect, two horizontal hydraulic cylinder 4 piston rod ends are connected with fixed cap 3, and be individually fixed on two clamping seats 6 by fixed cap 3 and bolt, clamping seats 6 bottom is provided with through hole in guide pole 2 position, clamping seats 6 is connected on guide pole 2 by through hole, then guide pole 2 play the guiding role and prevents clamping seats 6 moving direction from offseting, two clamping seats 6 tops have been bolted square clamping plate 7, square clamping plate 7 are connected on crossbeam by chute, the platform for place work piece is provided with in the middle part of crossbeam, for being connected to the column 10 in frame above platform, column 10 lower end is provided with vertically places and acts on the downward vertical hydraulic cylinder 9 of end, vertical hydraulic cylinder 9 piston rod end has been bolted pressure head web member 8, pressure head web member 8 being bolted effect end is hemispheric pressure head.
During utility model works, workpiece is positioned on the platform be located in the middle part of crossbeam, by the bolt turning square clamping plate 7 both sides, workpiece is clamped, foil gauge is sticked in the upper surface of workpiece, start two horizontal hydraulic cylinders 4 be located on mount pad 5, horizontal hydraulic cylinder 4 drives both sides clamping seats 6 to two lateral movements by piston rod, owing to clamping seats 6 being fixed with square clamping plate 7, then square clamping plate 7 under the effect of clamping seats 6 to two lateral movements, be fixed on the workpiece both sides under tension effect on square clamping plate 7, the correlationship of unrelieved stress and horizontal tension and compression can be detected, start vertical hydraulic cylinder 9, the pressure head web member 8 that vertical hydraulic cylinder 9 acts on end moves downward, pressure head web member 8 drives the pressure head be fixed on pressure head web member 8 to move downward, and push down workpiece, when being pressed onto certain position, vertical hydraulic cylinder 9 acts on end and moves upward, band dynamic head moves upward, read foil gauge reading on test specimen, the unrelieved stress of test specimen is calculated in conjunction with fixed load and pressure head hemisphere effect end diameter, the analog residue stress intensity that the unrelieved stress relatively calculated and hydraulic cylinder two apply, method indentation method being surveyed to unrelieved stress is assessed.
The foregoing is only preferred embodiment of the present invention; not thereby embodiments of the present invention and protection domain is limited; to those skilled in the art; should recognize and all should be included in the scheme that equivalent replacement done by all utilizations instructions of the present invention and diagramatic content and apparent change obtain in protection scope of the present invention.
