Embodiment Construction

[0019] The specific implementation manners of the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0020] Such as Figure 1-7 As shown, the present invention comprises a cylinder body 2 and a cylinder head 3 and a cylinder bottom 1 positioned at two ends of the cylinder body. The cylinder body 2, the cylinder head 3 and the cylinder bottom 1 are fixedly mounted together with nuts and bolts, and the piston 5 is slidably mounted on the cylinder body 2. Inside, both sides of the piston are respectively connected to the piston rod 4 and protrude from the cylinder head 3 and the cylinder bottom 1. The cylinder body 2 is provided with a first oil hole 201 connected to the front of the inner cavity of the cylinder body 2, and the cylinder body 2 is provided with a communication The second oil hole 202 in the middle of the inner cavity of the cylinder body 2, the third oil hole 203 and the fourth oil hole 204 connected to the...

Abstract

The invention relates to a steerable and differential hydraulic damping cylinder, which is characterized in that: a first oil hole which is communicated with the front part of the cavity of a cylinder body is formed in the cylinder body; a second oil hole which is communicated with the middle part of the cavity of the cylinder body is formed in the cylinder body; a third oil hole and a fourth oilhole which are communicated with the back part of the cavity of the cylinder body are formed in the cylinder body; the first oil hole, the second oil hole, the third oil hole and the fourth oil hole are axially formed in a cylinder body wall; the middle of the side face of a cylinder bottom is provided with an oil inlet hole which is communicated with the third oil hole or the fourth oil hole; and both sides of the cylinder bottom are provided with a first oil outlet hole and a second oil outlet hole which are communicated with the third oil hole and the fourth oil hole respectively. The damping cylinder has a simple and compact structure and low manufacturing cost, is convenient to use and maintain and lowers equipment manufacturing cost; a quick propelling travel and a slow propelling travel are realized in an entire travel by using two oil holes which are connected with different positions of the cavity of the cylinder body and the speed in the slow propelling travel is adjustable;moreover, a second use state can be realized by changing the installation position of the cylinder body.

Description

technical field [0001] The invention relates to a hydraulic oil cylinder, in particular to a steering and split-speed hydraulic damping cylinder. Background technique [0002] In some automatic equipment, the hydraulic cylinder is used to push the workpiece forward. When it is empty, it needs to be pushed quickly, and when it enters the working stroke, it needs to be pushed slowly. In the prior art, two hydraulic oil cylinders or a more complicated hydraulic system are usually required to realize the control of two strokes, which not only results in complex structure of the automatic equipment, high manufacturing cost, but also difficulty in use and maintenance. Contents of the invention [0003] In view of the above problems, the applicant has made researches and improvements to provide a steerable and split-speed hydraulic damping cylinder, which has a simple and compact structure, low manufacturing cost, and is easy to use and maintain. [0004] In order to solve the p...
