Abstract
The invention discloses an adjustable test fixture device, which comprises an H beam base, two support bases arranged on the H beam base and clamped pressure sheets arranged on the tops of the support bases; two pairs of support base guide grooves are arranged on an upper wing plate of the H beam base; and one support base is movably connected to each pair of support base guide grooves. The device disclosed by the invention is simple for operation and high in precision; the positions of the support bases can be adjusted through the guide grooves on the upper wing plate of an H beam, so that the distance between the support bases can be adjusted, thus, the purpose of applying to test pieces with different geometrical sizes can be achieved; different boundary types can be realized by replacing the types of the support bases on the upper wing plate of the H beam; and the H beam base can move, thus, the adjustable test fixture is convenient to experiment and test in different places and has a certain portability.
Description
Technical field:
The present invention relates to the test unit field, particularly a kind of static state and dynamic impact test grip device.
Background technology:
Standard static and dynamic test are used for the key property of test material or structure, and boundary condition is the freely-supported form, and the size of the test specimen of getting compares less, and relevant criterion is generally with reference to ASTM material test standard.And in practical engineering application; Except the basic static state and dynamic property of test material or structure; Also need, and the size of structure is bigger in the engineering, and boundary condition is not quite similar according to actual engineering demand research structure static state and dynamic property; Thereby must design the test fixture that is applicable to different operating modes with processing and manufacturing, will cause a large amount of wastes of material.
On supporting with the relevant experimental machine of present standard freely-supported test fixture, and for the pilot project of other type, the code test anchor clamps can not satisfy relevant testing requirements, and test fixture needs design in addition and processing.For the fixing test fixture in two ends, there not be the test standard of being correlated with yet, need be according to different test design different test fixtures does not possess certain versatility, is difficult to satisfy the test demand of various working in the engineering.
Summary of the invention:
The object of the present invention is to provide a kind of new type of adjustable joint formula test fixture device; This device is through the guiding of I-beam upper flange upper rail; Move left and right is simultaneously vertically through bearing; Realize the adjusting of standoff distance, thereby reach the purpose that is suitable for different geometrical size test test specimen, realize the controllability of test fixture.And, through changing the I-beam upper seat, realize the different boundary condition type, I-beam can move, and convenience makes an experiment in different places and tests, thereby realizes the versatility and the portability of test fixture.
In order to achieve the above object, the present invention adopts following technical scheme to be achieved.
A kind of adjustable test fixture device, what comprise the I-beam pedestal, be arranged on two bearings on the I-beam pedestal and be arranged on the bearing top props up compressing tablet admittedly.
The upper flange of said I-beam pedestal is provided with two pairs of bearing guide grooves or two pairs of rounds, is connected with a bearing on every pair of bearing guide groove or every pair of round.Said round is made up of 4-8 hole alinement.
In said bearing guide groove or the round bearing set bolt is installed, this bearing set bolt is connected with bearing.
Said bearing top is connected with through the compressing tablet bolt and props up compressing tablet admittedly.
The said compressing tablet top of propping up admittedly is provided with the freely-supported roll shaft.
The lower wing plate of said I-beam pedestal is provided with the pedestal set bolt.
Compare with existing test fixture device; Adjustable test fixture apparatus structure of the present invention is reasonable in design; Have the material of suitable different geometrical size and the test test specimen of structure; Not only can accomplish the material and the stryctyrak test test of standard, can also accomplish the material of two fixed ends and the experimental test of structure, have certain versatility.Apparatus of the present invention are simple to operate, and precision is high.Through the position of the adjusting of the guide groove on I-beam upper flange bearing, realize the adjusting of standoff distance, thereby reach the purpose that is suitable for different geometrical size test test specimen; Through changing the type of support on the I-beam upper flange, realize the Different Boundary type; The I-beam pedestal can move, and convenience makes an experiment in different places and tests, and has certain portability.
Description of drawings:
Gu Fig. 1 is an a kind of new type of adjustable joint formula test fixture of the present invention-assembling synoptic diagram.
