Problems solved by technology

The oil cylinder of the current hydraulic buffer circuit cannot keep shrinking after being retracted, and has a tendency to move forward, or the structure is complicated and difficult to control
[0003] The traditional buffer structure generally uses a one-way valve, which has a better buffer effect, but the cost is high

Embodiment Construction

[0016] The present invention will be described in further detail below with reference to the drawings and specific embodiments. The following embodiments are only descriptive and not restrictive, and the protection scope of the present invention cannot be limited by this.

[0017] A hydraulic cylinder with buffer function, such as figure 1 As shown, the cylinder body 6 is included. The cylinder head 3 and the cylinder bottom 13 are respectively sealed and installed at both ends of the cylinder body. A piston rod 7 is slid and inserted coaxially in the cylinder head. A piston 8 is fixedly mounted on one end of the piston rod. The other end of the piston rod is located outside the cylinder and a lifting ring 1 is fixed. The lifting ring is fixed with the piston rod by a nut 2 and the oil inlet 5 and the oil outlet 11 are respectively installed on both ends of the cylinder.

[0018] In this embodiment, an elastic rubber pad 10 is fixedly installed at the end of the piston, and the thi...

Abstract

The invention relates to a hydraulic cylinder with a buffering function. The hydraulic cylinder with the buffering function comprises a cylinder body, and both ends of the cylinder body are provided with a cylinder cover and a cylinder bottom respectively in a sealed mode; the inside of the cylinder cover is coaxially and slidingly provided with a piston rod in a penetrating mode, and one end of the piston rod is fixedly provided with a piston; both end walls of the cylinder body are provided with an oil inlet and an oil outlet respectively. The hydraulic cylinder with the buffering function is characterized in that one end portion of the piston, which corresponds to the cylinder bottom, is fixedly provided with an elastic member. The hydraulic cylinder effectively buffer the impact force of the piston onto the cylinder bottom through an elastic rubber cushion fixedly mounted on the end surface of the piston, and meanwhile, is simple in structure and low in cost. The hydraulic cylinder with the buffering function is simple in structure, easy to implement and scientific and reasonable in design, and can achieve good buffering effects without increasing existing costs.

Description

Technical field [0001] The invention belongs to the technical field of hydraulic cylinders, and specifically, is a hydraulic cylinder with a buffer function. Background technique [0002] In the transmission system of construction machinery, hydraulic cylinders play a very important role as the actuating mechanism. In some cases, the hydraulic cylinder serves as a buffer. For example, in assembly line operation, a buffer mechanism is required to transfer the workpiece from the previous station to the next station. Especially in the case of high speed and heavy weight, the effect of using oil cylinders to buffer the impact of the equipment forward is obvious and the action Smooth and effective. The oil cylinder of the current hydraulic buffer circuit cannot be kept in a retracted position after being retracted, has a tendency to move forward, or has a complicated structure that is not easy to control. [0003] The traditional buffer structure generally uses a one-way valve, which...
