Abstract
The utility model relates to a clamp for preparing standard test samples which are used in GB/T6329-1996 and take metal round bars as a base material, in particular to the clamp for preparing the standard test samples in an adhesive butt-joint and extension test, comprising a bottom plate. The bottom plate is provided with at least one group of clamps; and each group of clamps consists of two opposite V-shaped blocks. In the clamp for preparing the standard test samples in the adhesive butt-joint and extension test, the structure is simple, the clamp utilization rate is high, and the bottom plate is provided with multiple V-shaped blocks, so that multiple groups of test samples can be prepared by one time, and further, the working efficiency of preparation is greatly improved; by the positioning of positioning pins, the thickness of an adhesive layer can be accurately controlled; since the adhesiveness of an adhesive sample is higher, the bottom plate is provided with grooves and is in an overhead design, and if an adhesive sample drops in the adhesion process, the clamp can not be polluted, so that the service life of the clamp is long; and the residual adhesive samples are easy to be removed when the test samples are adhered.
Description
Technical field
The utility model relates to the anchor clamps that a kind of GB/T6329-1996 of being used for is the standard sample sample preparation of base material with the round metal bars, especially a kind of adhesive butt joint extension test standard sample Sample chuck.
Background technology
Estimate a kind of quality of tackifier, a most important job is the mensuration of bonded joint being carried out bonding strength.For the bonding strength of metal, the main project of mensuration has: shear resistance, tensile strength, inhomogeneous pullout strength, shear fatigue intensity, impact strength etc.Also can be according to data and request for utilization, (temperature, humidity, temperature alternating, chemical mediator etc.) carry out the test of various bonding strengths under varying environment.Because the effect that the glue-line in the cementing structure was generally stretched, shears and peeled off three kinds of power.From in essence, peeling off in fact also is that a kind of uneven film micro area stretches.
Stipulated tackifier open joint glue-joint strength assay method under the tensile force effect at ISO 6922 " tackifier---the mensuration of open joint pulling strengrth " and GB/T6329-1996 " mensuration of tackifier open joint pulling strengrth ".At first want the preparation standard sample before the mensuration, the sample joint is made of two side or circle bar-shaped adherend butt joints, its splicing face is perpendicular to the longitudinal axis of sample, the sample for preparing is generally measured its shear resistance or is just being drawn intensity on common universal testing machine, usually impose tensile load, till joint destroys.
Accurately locate for the assurance coupon during standard sample sample preparation, should use anchor clamps.But there is following shortcoming in the anchor clamps of recommending in the standard (Fig. 1): the clamp structure complexity; Because glue sample viscosity is higher, if glue sample drippage can cause anchor clamps to pollute, anchor clamps are not long serviceable life in the bonding process; The anchor clamps utilization factor is low, can only carry out the bonding of a sample at every turn; Unnecessary glue sample is difficult to remove during bonding sample.
The utility model content
The technical problems to be solved in the utility model is: in order to overcome the above-mentioned middle problem that exists, provide the adhesive butt joint extension test standard sample that a kind of clamp structure is simple, the anchor clamps life-span is long and utilization factor is high Sample chuck.
The technical scheme that its technical matters that solves the utility model adopts is: a kind of adhesive butt joint extension test standard sample Sample chuck, comprise base plate, and at least one group of anchor clamps are installed on the base plate, each group anchor clamps is formed by two relative V-blocks.
For cylindrical base material is slided in " V " type groove, adhesive butt joint extension test standard sample Sample chuck also comprises base material and register pin, all offer the pilot hole that is used for the precision machining spacing on two V-blocks, pilot hole and base material are fastening fixing by register pin.
For unnecessary glue sample can be struck off by hand, be separated with spacing between between two relative V-blocks.
In order to make the adhesive butt joint time avoid glue sample drippage to pollute anchor clamps, base plate is the bracing frame hollow structure, offers notch on the base plate, and notch is arranged between two V-blocks.
In order to place more cylindrical base material, 12 groups of anchor clamps are installed on the described base plate.
The beneficial effects of the utility model are, adhesive butt joint extension test standard sample Sample chuck of the present utility model, and this clamp structure is simple, anchor clamps utilization factor height, a plurality of V-blocks are housed on the base plate, can once prepare many group samples, improved the work efficiency of preparation widely; By the location of register pin, can accurately control bondline thickness; Because glue sample viscosity is higher, on base plate, offers groove and, if the glue sample drips, can not cause anchor clamps to pollute the anchor clamps long service life in the bonding process the built on stilts design of base plate; Glue sample unnecessary during bonding sample is removed easily.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is the prior art constructions synoptic diagram;
Fig. 2 is a structural representation of the present utility model;
Fig. 3 is that the utility model is placed the structural representation after base material docks.
