The outer frame 2 surrounds the main frame 1 and is equipped with protective wall panels. Correspondingly, a hydraulic system 4, an air source processing assembly 5, and a keyboard assembly 6 are installed on the rack to provide power to various devices and input control information.

[0031] During the testing process, the electrically adjustable string to be tested is placed on the lower fixture 300. The upper fixture 400 is driven downward by a lifting mechanism. The lower fixture 300 and upper fixture 400 clamp the electrically adjustable string to be tested, and the noise detection device performs an automatic noise test. Simulating the angle and operating conditions of the fully assembled electrically adjustable string, the equipment automatically tests functional parameters such as noise, operating current, operating stroke, and operating speed. This improves the stability and positioning accuracy of the equipment, and achieves high test repeatability, significantly enhancing the authenticity of the electrically adjustable string test results. Automatically performing noise testing under simulated operating conditions improves test accuracy and reliability while reducing workload.

[0032] Specifically, the turntable mechanism 100 includes a turntable frame 101 and a turntable 104 mounted on the turntable frame 101. The lower tooling 300 is mounted on the turntable 104 and is provided with a fixed bearing fixing seat 102. The turntable 104 is supported by a turntable bearing 103 so that the turntable 104 can rotate around a vertical axis. A balancing support device 105, a limit block 106, a non-return stop mechanism, a latch positioning mechanism and a proximity sensor 110 are provided below the turntable frame 101.

During operation, the servo motor 203 drives the lifting electric cylinder 201 to extend and retract, driving the sliding connecting plate 206 and the lifting connecting assembly 208 to move up and down.
