[0019] It should be noted that the tow line 82 is a conductive flexible metal line.

[0020] In actual use, the electric cylinder to be tested is placed on the jig 3, and the jig 3 is conveyed along the conveyor line 2. When the jig 3 is laser marked, the electric cylinder to be tested is marked by the laser marking mechanism 4, and the stroke of the electric cylinder is measured by the stroke testing mechanism 5. Then, when the electric cylinder follows the jig 3 into the silencer entrance 62, it contacts the outer shell of the electric cylinder to be tested through the tow line 82 for electrical conduction. When the electric cylinder leaks electricity, the current and voltage signals are transmitted along the tow line 82 to the withstand voltage tester 81, and then the withstand voltage tester 81 displays the value. Then, the operator listens to whether there is any abnormal sound when the electric cylinder to be tested is working in the silent room 61. The load condition of the electric cylinder is detected by the load testing mechanism 7. Then, according to the jig 3, it flows out of the silent room 61 along the silencer outlet 63 and is unloaded by the unloading mechanism.

Specifically, the No. 1 cylinder 531 drives the positioning block 532 to move downward, so that the positioning block 532 fixes the cylinder body of the electric cylinder. Then the output end of the electric cylinder starts to work, and the No. 1 CCD camera 563 is used to take pictures of the starting and ending positions of the output end of the electric cylinder to test the starting and ending distances of the output end of the electric cylinder.
