Description

Technical Field

[0001] The utility model relates to the technical field of hydraulic cylinders, in particular to a hydraulic cylinder installation structure. Background Art

[0002] The hydraulic cylinder is a hydraulic actuator that converts hydraulic energy into mechanical energy and performs linear reciprocating motion. It has a simple structure and reliable operation. When using it to achieve reciprocating motion, the deceleration device can be eliminated, and there is no transmission gap and the movement is smooth. Therefore, it is widely used in the hydraulic systems of various machines. When assembling the hydraulic cylinder, a hydraulic cylinder mounting structure is required to fix it.

[0003] The utility model patent with the announcement number CN212079819U discloses a hydraulic cylinder installation structure on a press, including: a hydraulic cylinder barrel, a hydraulic cylinder fixing seat on the press, and a locking nut assembled on the barrel, wherein the barrel has a radial shoulder at one end of the piston rod and an external thread for assembling the locking nut at the other end, and the fixing seat has a through hole for assembling the barrel. The improvements made are: increasing the diameter of the locking nut, distributing axial threaded holes circumferentially on the locking nut, and installing the locking nut's top screws in each threaded hole. The positive effect of the utility model is that the tightening pressure between the locking nut and the fixing seat is not formed by rotating the nut, and there is no need to weld a support on the circumference of the nut and use a jack to push the nut. The required tightening pressure of the nut on the fixing seat is distributed to multiple top screws, which simplifies the installation process and facilitates the installation and disassembly of the hydraulic cylinder on the press. There is an elastic buffering effect between the locking nut and the fixing seat, which has a significant effect in preventing the locking nut from loosening.

Manual oiling may cause uneven oil distribution. When installing the hydraulic lever, the internal lubricating oil is insufficient, resulting in more laborious installation. In this regard, we propose a hydraulic cylinder installation structure to solve the above problems. Utility Model Content
