Description

Testing arrangement of test aluminum zinc alloy template atress condition Technical Field The invention relates to the technical field of stress testing, in particular to a testing device for testing stress conditions of an aluminum zinc alloy template. Background The aluminum alloy is a common alloy material, has the advantages of light weight and the like, has wide application in the engineering field, is one of the aluminum-zinc alloys, and is necessary to test the stress condition of the aluminum alloy product in order to ensure the safety and reliability of the aluminum alloy product in the use process. For example, the patent with publication number CN118464592B discloses a test bench for testing stress condition of an aluminum zinc alloy template, in the device, two rolling type protective structures are arranged on two sides of an aluminum zinc alloy template workpiece and follow a traction clamping device to synchronously move for rolling or releasing, so that the problem that a tester is injured due to sputtering after the workpiece is broken is avoided. However, although the device can effectively protect the two sides of the aluminum zinc alloy template, obvious protection dead zones exist, and the upper part of the template is not covered at all, so that when the device is adopted to carry out stress test, once the aluminum zinc alloy template is broken, fragments generated by the breaking of the aluminum zinc alloy template can still splash upwards or upwards sideways, especially the two broken ends of the template, thereby causing safety threat to field testers, and the hidden danger of sputtering injury can not be fundamentally eliminated. Secondly, before the forced test is started formally, because the widths of the aluminum zinc alloy templates to be tested are different, the clamping process of the aluminum zinc alloy templates still needs to be finished by relying on manual operation. The traditional manual clamping mode not only needs a worker to manually adjust the clamping position and gradually apply the clamping force to ensure stability and is long in time consumption in the whole operation process, but also greatly occupies the whole period of the aluminum zinc alloy template test under the condition of batch test, so that the working efficiency of the test link is obviously reduced, and the actual requirement of high-efficiency test is difficult to meet. Disclosure of Invention Aiming at the problems in the prior art, the invention aims to solve the technical problems that when the existing testing device is used for carrying out stress testing on the aluminum zinc alloy template, the situation that the aluminum zinc alloy template breaks and sputters to cause injury to testers, particularly the two broken ends of the template, is caused, and because the aluminum zinc alloy templates to be tested are different in width, the aluminum zinc alloy templates need to be clamped by adopting the traditional manual mode, the whole process consumes longer time, and the working efficiency of a testing link is greatly reduced. In order to solve the technical problems, the invention adopts the following technical scheme that the testing device for testing the stress condition of the aluminum zinc alloy template comprises: The test bench, on the horizontal plane of the test bench, the stress direction of the aluminum zinc alloy template is a first direction, and the direction perpendicular to the stress direction is a second direction; The stress testing mechanism comprises a bottom plate, clamping pieces, suckers, telescopic pieces and first connecting plates, wherein the two bottom plates are arranged on the testing table in a sliding mode along the first direction, the two clamping pieces are arranged on each bottom plate in a sliding mode along the second direction, the suckers are arranged on one side, adjacent to the two clamping pieces, of each bottom plate, the two telescopic pieces are arranged in a one-to-one correspondence mode with the two clamping pieces on the same bottom plate, the two telescopic pieces are arranged on the testing table in a sliding mode along the second direction and are located between the two bottom plates, two ends of each telescopic piece are connected with the corresponding clamping pieces on the two bottom plates through the first connecting plates, one end of each first connecting plate is hinged to each telescopic piece, and the other end of each first connecting plate is hinged to each clamping piece so as to split thrust of each telescopic piece into component force towards the first direction and the second direction. An arc-shaped protective cover rotatably mounted on the test bench to enable the arc-shaped protective cover to rotate above or below the test bench, and And when the arc-shaped protective cover rotates from the lower part of the test bench to the upper part of the test bench, the arc-shaped protective cover controls the two clamping p
