[0002] With the rapid development of the machinery manufacturing industry, hydraulic cylinders, as devices that convert hydraulic oil pressure into push and pull force, are increasingly in demand across various manufacturing sectors and are an indispensable part of automated processing. To ensure the stable performance and long service life of hydraulic cylinders in the manufacturing process, an advanced hydraulic cylinder lifespan testing device is needed to test and sample manufactured cylinders. Currently, hydraulic cylinder lifespan testing equipment is inefficient and provides inaccurate data; therefore, a more efficient and accurate testing device is required. Utility Model Content

The piston of the oil cylinder is connected to the transmission shaft through the connecting sleeve. One end of the spherical bearing is connected to the transmission shaft, and the other end is connected to the eccentric shaft. The eccentric shaft is connected to the geared motor through the coupling. A signal ring is provided on the eccentric shaft, and the signal ring is electrically connected to the detection switch.

[0005] The geared motor is mounted on the base, the hydraulic cylinder is mounted on the connecting plate, the transmission shaft is located on the support plate, and the connecting plate, support plate, and base are mounted on the testing platform to form a support structure with the testing platform.

[0006] The drive shaft passes through the support plate, and a copper sleeve is provided between the drive shaft and the support plate.

One end of the spherical bearing 7 is connected to the transmission shaft 6, and the other end is connected to the eccentric shaft 14. The eccentric shaft 14 is connected to the geared motor 8 through the coupling 11. A signal ring 13 is provided on the eccentric shaft 14, and the signal ring 13 is electrically connected to the detection switch 12.

[0018] The geared motor 8 is mounted on the base 10, the oil cylinder is mounted on the connecting plate 3, and the transmission shaft 6 is located on the support plate 5. The connecting plate 3, the support plate 5, and the base 10 are mounted on the testing table 1, forming a support structure with the testing table 1.

[0019] The drive shaft 6 passes through the support plate 5, and a copper sleeve 15 is provided between the drive shaft 6 and the support plate 5.

[0021] The geared motor 8 is electrically connected to the control box 9, which is mounted on the testing platform 1.

[0022] The hydraulic cylinder 2 is connected to the connecting sleeve 4, the drive shaft 6, the spherical bearing 7, the eccentric shaft 14, and the coupling 11 to form a transmission chain. The control box 9 adjusts the rotation speed of the geared motor 8, and the speed can be adjusted remotely. The operating status can be monitored through the display screen. The detection switch 12 and the signal ring 13 are combined to record the number of reciprocating strokes of the hydraulic cylinder, and the recorded data is accurate.

[0023] The hydraulic cylinder lifespan testing equipment utilizes the reciprocating motion principle to achieve the reciprocating motion of the piston inside the hydraulic cylinder 2, accelerating the wear of the inner seal ring. It uses detection signals to detect the operating speed and number of cycles. The equipment consists of a geared motor 8 driving an eccentric shaft 14 via a coupling 11.
