Description

Technical Field

[0001] This utility model relates to the field of tensile testing technology for materials, and more specifically, to a multifunctional clamp for tensile specimens. Background Technology

[0002] Currently, in the mechanical property testing of materials, there are strict standards for the requirements of the specimens. However, the raw materials used to process the specimens may not meet these requirements. During the tensile testing process, the specimen is fixed at both ends using a tensile testing machine, and a load is applied. Various mechanical properties are usually measured according to different tensile conditions. Tensile testing and measurement need to be performed simultaneously. However, measuring instruments vary in size and installation conditions. Tensile testing may not meet the installation requirements of the measuring instruments. When the measuring instruments cannot be directly fixed to the specimen, they are often bound with tape. This method is not only inconvenient to operate, but the position is also prone to slight changes during the test, thus affecting the test results. In addition, when the specimen length is small, after the tensile testing machine fixes the specimen from both sides, there is not enough space for the measuring instruments to be fixed to the specimen.

[0003] Therefore, how to solve the above-mentioned technical problems has become the subject of this utility model. Utility Model Content

[0004] In view of the problems existing in the prior art, the purpose of this utility model is to provide a multifunctional clamp for tensile specimens that is easy to use, highly applicable, and convenient for tensile testing.

[0005] The technical solution adopted by this utility model to solve its technical problem is as follows: This utility model provides a multi-functional clamp for tensile specimens, characterized in that it includes a clamping plate, a base is fixedly connected to the end of the clamping plate, a cover plate is connected above the base, a slide is connected to the side of the cover plate away from the clamping plate, and a clamping component is slidably fitted on the slide.

[0006] The base has a rectangular groove at the top, and the cover plate has a top groove of the same size at the bottom corresponding to the groove.

[0007] The base is fixedly connected to the lower side of the end of the clamping plate. A T-shaped slot is provided at the center of the upper side of the end of the clamping plate. A T-shaped clip that engages with the slot is fixedly connected to the center of the end of the cover plate facing the clamping plate.

[0008] The base has several through-holes evenly distributed at the bottom, and the cover plate has several through-holes corresponding to the first threaded holes at the top. A first bolt assembly is threadedly connected between the first threaded hole and its corresponding second threaded hole.

[0009] The base has a pair of lower half-slide grooves symmetrically opened on both sides of the top near its edge, and the cover plate has a pair of upper half-slide grooves corresponding to the lower half-slide grooves on both sides of the bottom. The lower half-slide grooves have at least two third threaded holes, and the upper half-slide grooves have a fourth threaded hole corresponding to the third threaded holes.

[0010] There are two slideways. One side of the slideway is slidably engaged with the upper half slideway and the lower half slideway located on the same side. The slideway has a fifth threaded hole corresponding to the third threaded hole and the fourth threaded hole. The fifth threaded hole, the fourth threaded hole, and the third threaded hole are directly threadedly connected to a second bolt assembly.

[0011] The clamping component includes sliding sleeves symmetrically slidably connected to the two slide rails, and a U-shaped connecting plate with its opening facing downward is fixedly connected between the tops of the two sliding sleeves. A pair of clamping plates are symmetrically arranged on both sides of the connecting plate.

[0012] The outer wall of the sliding sleeve is threaded with a fixing bolt that mates with the outer wall of the slide.

[0013] The top of the connecting plate is provided with a through sliding groove, and two sliding blocks are symmetrically slidably connected to both sides of the sliding groove. Each sliding block is connected to a clamping plate at its bottom.

[0014] A pair of upper ear plates are symmetrically fixedly connected to the top two sides of the connecting plate. A bidirectional lead screw is rotatably connected between the two upper ear plates. The bidirectional lead screw passes through the two sliding blocks and is threadedly connected to the sliding blocks.

[0015] One end of the bidirectional lead screw passes through the outer side of the upper ear plate and is coaxially fixedly connected to a worm gear. A worm is engaged on the lower side of the worm gear. The two ends of the worm are rotatably connected between a pair of side ear plates. The side ear plates are fixedly connected to one side of the connecting plate. One end of the worm passes through the outer side of the side ear plate and is coaxially fixedly connected to a rotating wheel.

[0016] Both the bottom groove and the top groove are provided with gaskets on their inner sides, and the gaskets have a number of openings corresponding to the first bolt assembly.

[0017] The two clamps are evenly provided with a number of rubber anti-slip particles on opposite sides.

[0018] In actual use, the present invention is as follows: the sample is drilled, and the drilled sample is placed between two gaskets. One side of the sample is fixed between the base and the cover plate by the first bolt assembly. At the same time, the slide is fixed between the upper half slide and the lower half slide by the second bolt assembly. The other side of the sample is fixed in the same way. The slide can be selectively installed as needed. After adjusting the clamping components to clamp and fix the testing instrument, the clamping plates on both sides are installed on the tensile testing machine to carry out the test.

[0019] The beneficial effects of this utility model are as follows:

[0020] 1. This utility model can connect samples that are not long enough to the tensile machine through a clamping plate, thereby leaving room for the installation of testing instruments;

[0021] 2. This utility model uses clamping components on the guide rail to fix the testing instrument in the testing position. When the testing instrument and the sample cannot be directly attached and fixed, it is convenient to adjust the position of the testing instrument for measurement, and at the same time, it ensures that the position will not shift during measurement and affect the testing data.

[0022] 3. The clamping component of this utility model achieves the clamping function of the clamping plate through the cooperation of the worm gear and worm, and the self-locking structure of the worm gear and worm ensures the stability of the clamping. Attached Figure Description
