Problems solved by technology

However, in the application practice of multi-cylinder synchronous loading, it is often difficult to realize multi-cylinder synchronous loading due to factors such as the accuracy and error of control components, resulting in unbalanced loads, unbalanced forces, and even mechanical structural parts being stuck and damaged.

Abstract

The invention relates to a rigid high-precision hydraulic synchronous device. The lower portions of a left cavity and a right cavity of a first synchronous cylinder are connected with one end of a first control valve group. The other end of the first control valve group is connected with a pressure gauge and the output end of the high-pressure oil tank. The output end of the high-pressure oil tankis provided with an electromagnetic reversing valve. The lower portions of a left cavity and a right cavity of a second synchronous cylinder are both connected with one end of a second control valvegroup. The other end of the second control valve group is connected with the pressure gauge and the output end of the high-pressure oil tank. The upper portions of the left cavity and the right cavityof the first synchronous cylinder are both connected with one end of the third control valve group. The other end of the third control valve group is connected with the left cavity of a first hydraulic cylinder through a hydraulic pipeline. The upper portions of the left cavity and the right cavity of the second synchronous cylinder are connected with one end of a fourth control valve group. Theother end of the fourth control valve group is connected with the left cavity of a second hydraulic cylinder through a hydraulic pipeline. The right cavity of the first hydraulic cylinder and the right cavity of the second hydraulic cylinder are connected in parallel through a hydraulic pipeline and then are connected with the output end of the high-pressure oil tank through an electromagnetic reversing valve. The rigid high-precision hydraulic synchronous device can rigidly guarantee that the hydraulic cylinders needing adjustment synchronously act.

Description

technical field [0001] The invention relates to the field of synchronous control of hydraulic oil cylinders, in particular to a rigid and high-precision hydraulic synchronous device. Background technique [0002] Hydraulic cylinders are hydraulic components widely used in industrial and agricultural industries. They are often used in hydraulic pressure loading, platform lifting and other occasions. They have the obvious advantages of simple operation, economical and practical, and high reliability. With the large-scale and heavy-duty mechanical products, there are more and more requirements for the working resistance of hydraulic cylinders. As we all know, the working resistance of a hydraulic cylinder is directly proportional to the cylinder diameter. Under the same pressure conditions, the larger the cylinder diameter, the greater the working resistance. However, due to the larger bore of the hydraulic cylinder, its processing difficulty and cost have increased significan...
