Description

Technical Field

[0001] The utility model relates to the technical field of hydraulic oil cylinders, in particular to a hydraulic oil cylinder with a guide mechanism. Background Art

[0002] Hydraulic cylinder is a common hydraulic actuator, usually used to convert hydraulic energy into mechanical energy. It is composed of cylinder barrel, piston, piston rod, seal, inlet and outlet oil ports and other components. The principle is to use liquid to transmit pressure in a closed container and control the flow direction and flow rate of the liquid to achieve the movement of the piston. When the hydraulic cylinder receives the hydraulic energy provided by the hydraulic system, the piston in the hydraulic cylinder will be pushed by the pressure, thereby generating linear motion or rotational motion to complete the corresponding work task.

[0003] Most of the existing hydraulic cylinders currently lack a guiding mechanism, which makes them easily affected by external factors during operation, resulting in operation deviations, thereby affecting their accuracy and stability.

[0004] Patent document CN217233970U discloses a buffer hydraulic cylinder, "including a hydraulic cylinder body, a fixing plate and a hydraulic lifting plug, wherein a guide rod is installed inside the hydraulic cylinder body, a mounting plate is provided on one side of the hydraulic cylinder body, and a sealing plug matching the inner wall of the hydraulic cylinder body is installed on the inner side of the mounting plate, a fixing plate is provided inside the mounting plate, and a hydraulic lifting plug matching the inner wall of the hydraulic cylinder body is provided on the outer wall of the fixing plate, the inner side of the hydraulic lifting plug matches the outer wall of the guide rod, and the inner side of the hydraulic cylinder body is provided with a fixing plate. The inner wall is provided with a fixed groove. The buffer hydraulic cylinder squeezes the arc buffer plate and the shock absorbing spring through the hydraulic lifting plug, so that the arc buffer plate and the shock absorbing spring are tightened in the guide rod, and the arc buffer plate and the shock absorbing spring drive the hydraulic lifting plug to reset under the action of their own elastic force, thereby facilitating the position of the hydraulic lifting plug to have a shock absorbing and buffering effect. However, the buffer hydraulic cylinder in the above-mentioned public document mainly considers shock absorbing and buffering, but does not consider the problem of guiding the hydraulic cylinder. Therefore, it is necessary to develop a hydraulic cylinder with a guiding mechanism. Utility Model Content

[0005] The purpose of the utility model is to provide a hydraulic oil cylinder with a guiding mechanism to solve the technical problem of guiding the operation of the hydraulic oil cylinder proposed in the above background technology.

[0012] Compared with the prior art, the beneficial effects of the utility model are:

[0013] 1. The utility model facilitates guiding the operation of the hydraulic cylinder with a guide mechanism by installing a guide rod and a guide cylinder. When the hydraulic cylinder with a guide mechanism is used, the cylinder body drives the piston rod to move, and the movement of the piston rod drives the object to move. When the piston rod moves, the positioning ring is driven to move. The movement of the positioning ring drives the guide rod to move inside the guide cylinder through the connecting block. When the guide rod moves inside the guide cylinder, the guide cylinder limits and guides the guide rod, so that the guide rod moves smoothly, which in turn makes the piston rod move smoothly, thereby achieving the purpose of guiding and improving the running stability.

[0014] 2. The utility model improves the heat dissipation efficiency of the hydraulic cylinder with a guide mechanism by installing a fan. The fan will generate wind when it is working. The wind will flow through the through hole to the surface of the cylinder body, thereby dissipating heat and cooling the cylinder body. When the guide rod moves, it will drive the frame to move. When the frame moves, it will dissipate heat and cool different positions of the cylinder body, thereby achieving the purpose of improving the heat dissipation efficiency.
