The invention belongs to the technical field of testing, and particularly relates to an electrical automation automatic adjustment test board which comprises a cabinet body, the top of the cabinet body is connected with a supporting table through bolts, one side of the top of the supporting table is connected with a test frame through bolts, and one side of the test frame is provided with a plurality of testers. A clamping mechanism is arranged at the top of the supporting table, base plates are arranged on the two sides of the top of the clamping mechanism, fixing clamps are connected to the tops of the two base plates through bolts, through openings are formed in the two sides of the tops of the two fixing clamps in a penetrating mode, and fixing mechanisms are arranged between the two through openings and the fixing clamps. Through cooperation between the clamping mechanism and the fixing mechanism, the to-be-tested piece can be effectively fixed, so that the test stability of the to-be-tested piece is improved, and the situation that the position of the to-be-tested piece deviates due to vibration in the test process is prevented; therefore, the lead between the to-be-tested piece and the tester falls off to influence the test of the to-be-tested piece.

This invention relates to the field of film shrinkage measurement technology, encompassing clamping plates, a fixture for preventing sample strip detachment, and a device for measuring the heat shrinkage properties of films. The fixture includes fastening bolts and two symmetrically arranged clamping plate bodies. The fastening bolts pass through and connect the two clamping plate bodies, clamping the sample strip between them. A first arc-shaped groove is formed on one side of each clamping plate body, and a second groove extending perpendicular to the length of the sample strip is formed on the opposite side. A rubber pad is placed within the second groove, and the rubber pad has several protrusions arranged in an array to compress the end of the sample strip. This clamping plate structure increases the friction between the clamping plate and the sample strip, making it less likely for the sample strip to detach. Simultaneously, the clamping force is evenly distributed, avoiding localized damage to the sample strip and reducing the risk of detachment. The control system of the film heat shrinkage performance measuring device combines the detected pressure data to control the device's operating status in real time, reducing wasted time and improving testing reliability.
