Description

Technical Field

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

[0002] The cylinder is an actuator widely used in mechanical equipment. Its main function is to convert hydraulic energy into mechanical energy to achieve linear reciprocating motion or swinging motion. The cylinder is composed of components such as cylinder barrel, cylinder head, piston, piston rod and sealing device.

[0003] With the continuous development of modern mechanical equipment, cylinders are used more and more widely in mechanical equipment. However, traditional cylinders do not have a guide mechanism, and the piston rod is easily subject to friction and interference from the inner wall of the cylinder during reciprocating motion, resulting in unstable piston rod movement. Therefore, in order to improve the performance and reliability of the cylinder, it is of great significance to study a cylinder with a guide mechanism. Utility Model Content

[0004] The purpose of the utility model is to provide an oil cylinder with a guide mechanism to solve the problems raised in the above background technology.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: an oil cylinder with a guide mechanism, comprising a cylinder body and a power rod, the left side of the cylinder body is clamped with a cylinder bottom, the right side of the cylinder body is clamped with a cylinder cover, the right side of the power rod is fixedly connected with a movable ring, the outer surface of the cylinder bottom is clamped with a first sealing sleeve, the inner wall of the cylinder cover is clamped with a first sealing ring, the inner wall of the cylinder cover is clamped with a second sealing ring, the left side wall of the cylinder cover is fixedly connected with a guide ring, the outer surface of the cylinder cover is clamped with a sealing gasket, the outer surface of the power rod is clamped with a piston, the outer surface of the piston is clamped with a buffer pad, the outer surface of the piston is clamped with a guide sleeve, the outer surface of the piston is clamped with a wear-resistant ring, and the outer surface of the piston is clamped with a second sealing sleeve.

[0006] Wherein, the outer surface of the power rod is threadedly connected with a fixing bolt.

[0007] Wherein, an oil outlet is provided on the outer surface of the cylinder body.

[0008] Wherein, a first oil inlet is opened on the outer surface of the cylinder bottom, and a second oil inlet is opened on the right side of the cylinder bottom.

[0009] Wherein, a first dust cover is clamped on the inner wall of the cylinder head, and a second dust cover is clamped on the outer surface of the cylinder head.

[0010] Wherein, a buffer pad is fixedly connected to the right side surface of the cylinder bottom.

[0011] Wherein, a fixing ring is welded on the left side of the cylinder bottom.

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

[0013] The utility model ensures that the power rod moves along a straight track inside the cylinder body through the action of the guide sleeve and the guide ring, avoids the power rod from being deflected due to the lateral force, thereby improving the guiding accuracy of the oil cylinder. The guide sleeve and the guide ring can reduce the friction between the power rod and the cylinder body, reduce wear, and extend the service life of the oil cylinder. The guide sleeve and the guide ring can ensure the stability of the power rod during the movement, avoid vibration and noise, and improve the movement performance. The guide sleeve and the guide ring can increase the load capacity of the oil cylinder, so that the oil cylinder can withstand a larger load, thereby realizing more complex mechanical movements. Since the return movement is restricted by the guide sleeve and the guide ring, the power rod can be prevented from accidentally moving due to external factors such as impact, vibration, etc., thereby ensuring the safety of operation.

[0021] The outer surface of the power rod 8 is threadedly connected with a fixing bolt 22, and the fixing bolt 22 can easily disassemble the piston 23, which is convenient for maintenance and overhaul and reduces maintenance costs.

[0022] The outer surface of the cylinder body 1 is provided with an oil outlet 5, and the oil outlet 5 can discharge the hydraulic oil in the cylinder to facilitate replacement of the hydraulic oil or maintenance and repair.

[0023] Among them, a first oil inlet 4 is opened on the outer surface of the cylinder bottom 2, and a second oil inlet 10 is opened on the right side of the cylinder bottom 2. The first oil inlet 4 and the second oil inlet 10 can transport hydraulic oil to the inside of the cylinder to provide power for the cylinder, so that the cylinder can complete various complex mechanical movements.

[0024] Among them, the inner wall of the cylinder head 6 is clamped with a first dust cover 11, and the outer surface of the cylinder head 6 is clamped with a second dust cover 15.

The power rod 8 moves along the straight track inside the cylinder body 1 through the guiding effect of the guide sleeve 17 and the guide ring 14. When the power rod 8 reaches one end of the cylinder body 1, the hydraulic oil continues to push the power rod 8 to overcome the friction between the piston 23 and the cylinder body 1 and perform a return motion. During the return motion, the guide sleeve 17 and the guide ring 14 continue to guide the power rod 8 to move along the straight track inside the cylinder body 1. The reciprocating motion of the power rod 8 drives the external load to move accordingly, realizing various complex mechanical actions. At the same time, the hydraulic oil will also be discharged from the oil cylinder through the oil outlet 5 and return to the hydraulic system.
