Embodiment Construction
[0023] In order to make the technical means, creative features, goals and effects achieved by the present invention easy to understand, the present invention will be further described below in conjunction with specific illustrations.
[0024] see figure 1 and figure 2 , a packing belt tensile test jig given in the figure includes a fixed seat 100 , a fixed compression plate 200 , a bracket plate 300 , a movable compression plate 400 and a wrench assembly 500 .
[0025] The fixing base 100 uses the pin hole 110 into which the pin is inserted and the corresponding preset pin hole on the fixing base to fix the fixing base 100 on the stretching equipment. One side of the fixed pressure plate 200 is fixed on the fixed base 100 by two bolts 210, and the bolts 210 are at least two and should be arranged symmetrically, so as to effectively prevent the relative rotation of the fixed pressure plate 200 relative to the fixed base 100. The other side of the plate 200 is provided with a...

The invention discloses a packing belt stretching test clamp. The packing belt stretching test clamp comprises a fixing seat, a fixed pressing plate, a supporting plate, a movable pressing plate, and a wrench assembly, wherein the fixing seat is fixedly mounted on a stretching device; one side of the fixed pressing plate is fixed on the fixing seat through at least two bolts; the two sides of the supporting plate are respectively supported above the fixed pressing plate through two supporting plate supporting pillars, and a threaded hole is formed in the center of the supporting plate; the movable pressing plate is positioned between the fixed pressing plate and the supporting plate; the wrench assembly is used for controlling the ascending and descending of the movable pressing plate. The invention further discloses an assembly method for the packing belt stretching test clamp. All parts are independently molded and then assembled through a simple technique. Therefore, the production technique is simple, and the strength of each part is guaranteed; the clamp after assembly has a firm and reliable overall structure, is convenient to use, and achieves good practical performance and remarkable clamping effect.
Description
technical field [0001] The invention relates to the technical field of tensile test fixtures, in particular to a packing belt tensile test fixture and an assembly method thereof. Background technique [0002] When packing CNG (compressed natural gas) cylinders, packing tape is usually used. In order to ensure the firm packing, it is necessary to carry out corresponding tensile tests on the packing tape. In the prior art, when carrying out the tensile test on the packing belt, the two ends of the packing belt are first fixed on the clamps on the tensile testing equipment and then tested. However, due to the defects of the clamp itself, as the tensile force gradually increases, the packing The tape can slip from or out of the grips, making inaccurate data obtained from the tensile test. [0003] At present, there are also some clamps for tensile testing in the prior art, for example, a steel wire tensile test testing clamp disclosed in Chinese patent application document No. ...
