Description
Technical field
The utility model relates to a kind of multifunctional stretching test fixture, can be used for common puller system, not only can realize the test of sample pulling strengrth, and can realize the test of sample shear intensity.
Background technology
Tension test is that the research material mechanical property is the most basic, application experiment the most widely.Because test method is simple and be easy to obtain comparatively reliable experimental, widespread use tension test mechanical property of coming test material all in engineering and laboratory.
Anchor clamps are essential important component on the various tension testers; But mostly being two clamping plates, the anchor clamps on the common puller system have one to fix; Another one can move freely, and can only can not accomplish like the test of tackifier to the shear resistance of metallic bone to the pulling strengrth test of single straight line sample; Need special anchor clamps if accomplish the test of shear resistance; And the clamping mode of these anchor clamps mostly is pneumatic pinch or hydraulic clamp, and design cost is higher, can not be accepted extensively by middle-size and small-size laboratory.
The applicant adopts two fishbolts to be connected with clamping plate through slide block to the clamping part of the shortcoming proposition anchor clamps of existing tensile test fixture; So both can realize rotatablely moving of fishbolt changed into the rectilinear motion of clamping plate; Can realize moving freely of two clamping plates again, go for the clamping of different-thickness sample like this.Because the clamping mode that anchor clamps adopt manually clamping and mechanical grip to combine has greatly been practiced thrift cost, has obtained good actual effect.
The utility model content
Can only accomplish the monistic deficiency of straight line sample pulling strengrth test in order to overcome existing tensile test fixture; The utility model provides a kind of multifunctional stretching test fixture; These anchor clamps can not only be realized the test of sample pulling strengrth, and can accurately accomplish such as the test of tackifier to the shear resistance at metallic bone interface.
The utility model solves the technical scheme that its technical matters adopted: a kind of multifunctional stretching test fixture; Form by clamp body 1, first fishbolt 2, slide block 3, first clamping plate 4, second fishbolt 5, slide block 6, second clamping plate 7 and 8 on rule; It is characterized in that: clamp body adopts the U-shaped structure; First fishbolt 2 and second fishbolt 5 and clamp body 1 are connected through acme thread; The right cylinder of fishbolt end and the fluting socket on the slide block, clamping plate is connected through pin with slide block, the rule 8 of the location easy for installation, top of clamp body.The clamping plate of anchor clamps drives with two fishbolts that can move freely.The end of fishbolt is useful on the cylindrical cap and the outer-hexagonal cap that is used for mechanical grip of manual clamping.
Because last lower clamp adopts the U-shaped design of symmetry fully, so only above anchor clamps are the example explanation.The clamping part of anchor clamps mainly is made up of first fishbolt 2 and second fishbolt 5, slide block 3 and 6 and first clamping plate 4 and second clamping plate 7, adopts the design of two bolt types, the position of the different-thickness flexible clamping plate that they can be per sample.Design through slide block; Realization changes rotatablely moving of fishbolt into the pure rectilinear motion of clamping plate; Can guarantee in the process that clamps, can not cause the rotation of clamping plate like this, and the power in the drawing process passes to puller system by the surface of contact of slide block and clamp body, and can not pass to puller system by screw thread; Can avoid causing the destruction of screw thread like this, prolong the serviceable life of anchor clamps.Being used of last lower clamp high scale chi can be confirmed the position of sample exactly, should sample be clipped to the centre position of clamp body during clamped sample as far as possible, to guarantee the accuracy of measurement result.The end of fishbolt is made up of cylindrical cap and outer-hexagonal cap.Cylindrical cap is used for manual operation, and the position of the thickness manual positioning clamping plate that it can be per sample is flexible to operation.The outer-hexagonal cap is mainly used in the mechanically actuated behind the manual positioning, guarantees that sample can finally clamp.
The design's last lower clamp adopts the symmetrical expression design, and above anchor clamps are example explanation now, and it mainly is made up of clamp body 1, first fishbolt 2, slide block 3, first clamping plate 4, second fishbolt 5, slide block 6, second clamping plate 7 and rule 8.
Concrete assembling process is: at first with the polished rod part of first fishbolt 2 and second fishbolt, 5 thread heads and the slotted section socket of slide block 3 and 6.The polished rod of fishbolt thread head mainly contains big column and small column two parts; The diameter of small column is less than the size of the opening portion on the slide block circular hole; During small column pack into circular hole along the opening portion on the slide block circular hole, in the groove of big column this moment along with the slide block of packing into.The diameter of small column guarantees that less than the diameter of circular hole on the slide block small column can rotate freely on the fishbolt polished rod in the slide block circular hole.The diameter of big column guarantees that greater than the diameter of circular hole on the slide block slide block and fishbolt can not break away from the horizontal direction on the fishbolt.After accomplishing the assembling of first fishbolt 2 and second fishbolt 5 and slide block 3 and 6; They are packed into from the manufactured threaded hole in the clamp body outside; And threaded portion screwed in clamp body, treat that pin-and-hole on the slide block exposes clamp body fully after, again first clamping plate 4 and second clamping plate 7 are connected on slide block 3 and 6 through pin respectively; At last rule is riveted on the clamp body, accomplishes the complete assembling process of anchor clamps.
The design's major advantage is the range of application that has enlarged anchor clamps, and it not only can accomplish the pulling strengrth test of same straight line sample, and can accomplish such as tackifier the shear resistance of non-same straight line samples such as metallic bone is measured.Last lower clamp adopts complete symmetric design, and the part manufacturing is simple, and is easy for installation, and cost is low.Through the rule on the clamp body up and down, can accomplish accurate clamping to sample, the destruction of avoiding sample to receive additional force guarantees precision of test result.Adopt the zigzag design on the clamping plate face, prevent that sample from skidding in the tension test process.
Thereby the utility model has overcome the anchor clamps of existing puller system has only single clamping surface can move the deficiency that can only accomplish single strength test, and the improvement design through anchor clamps can be moved two clamping surfaces of anchor clamps, has enlarged the range of application of anchor clamps.Through the composite design of fishbolt and slide block, change rotatablely moving of fishbolt the rectilinear motion of slide block into, realized that the flexible straight line of clamping plate moves.According to different sample thickness; Cooperate rule on the anchor clamps to confirm the position of clamping plate, make anchor clamps have the function that pulling strengrth and shear resistance are tested concurrently, greatly improved the multifunctionality of anchor clamps; Practiced thrift cost, centering small test chamber has great practical value.
The beneficial effect of the utility model is, anchor clamps can be accomplished the test of pulling strengrth on common puller system, also can accomplish the test of shear resistance, and anchor clamps just can be accomplished multinomial test, have enlarged the range of application of anchor clamps.
