TECHNICAL FIELD

[0001] The utility model relates to the technical field of oil cylinder especially relates to an oil cylinder synchronous number switching system. BACKGROUND

[0002] In the application scene of industrial hydraulic system, the oil cylinder synchronous control technology is crucial to guarantee the stability and accuracy of mechanical equipment operation. In many industrial operations, it is often necessary to flexibly adjust the number of synchronous oil cylinders according to the actual working condition. For example, in the scene of large-scale hydraulic forming equipment, shipbuilding hoisting device, and positioning tooling of automatic production line, the number of synchronous oil cylinders will change with the change of processing technology and load.

[0003] However, the existing oil cylinder synchronous technology has significant defects. At present, there is a lack of effective system that can realize the number conversion (switching) of multiple synchronous oil cylinders in the industry. When the actual operation demand is switched from one number of synchronous oil cylinders to another, for example, from 9 oil cylinder synchronous operation to 7 oil cylinder synchronous operation, the commonly used method is to replace the synchronous motor. Specifically, the synchronous motor with 9 oil outlets is replaced by the synchronous motor with 7 oil outlets. This solution not only causes great waste of resources, but also requires additional investment in the purchase of new synchronous motors, and the old motors replaced are often idle due to their inability to adapt to other scenarios. At the same time, frequent replacement of synchronous motors makes the structure of the entire hydraulic system increasingly bulky. Each replacement requires the layout and installation of the system's pipes, connectors, etc., which not only increases the floor area of the system, but also significantly increases the difficulty of system maintenance, increases the risk of failure, reduces the reliability of equipment operation, greatly limits the adaptability and efficiency of the hydraulic system under complex working conditions, and makes it difficult to meet the requirements of modern industrial production for equipment flexibility, economy, and reliability. In view of this, the utility model proposes an oil cylinder synchronous number switching system. SUMMARY

[0006] Optionally, the multiple groups of oil outlets evenly distribute the oil outlet amount of the synchronous motor.

[0007] Optionally, the first pipeline communicates with the second pipeline and the third pipeline through the three-way valve.

[0008] Optionally, the number of interfaces of the multi-way joint corresponds to the number of the second pipelines.

[0009] In summary, the present application includes at least one of the following beneficial technical effects:

[0010] The utility model discloses through the help of three -way valve carries out the oil circuit switching, and the system can flexibly reduce the number of oil cylinder participating in the work, and simultaneously avoids the flow and pressure imbalance caused by the blockage of oil outlet or the connection oil tank, guarantees the remaining working oil cylinder to obtain stable, accurate oil supply, maintains the stability and accuracy of equipment operation.

[0011] Further, by constructing the oil liquid return path composed of the third pipeline and the multi-way joint, the oil liquid can return to the synchronous motor for redistribution, avoiding the replacement of the synchronous motor, reducing resource waste, simplifying the system structure and reducing the maintenance difficulty.

[0022] Embodiment:

[0023] As shown in Figure 1 and Figure 2 The present application provides an oil cylinder synchronous number switching system, which comprises a synchronous motor 1. The synchronous motor 1 provides balanced oil driving for the whole system by virtue of its stable power output characteristics. An oil inlet pipe 2 is connected to the oil inlet of the synchronous motor 1, so as to facilitate the delivery of oil into the synchronous motor 1 through the oil inlet pipe 2.

[0024] Specifically, the switching system includes nine groups of oil outlets 3 arranged on the synchronous motor 1. The nine groups of oil outlets 3 are designed to be uniformly distributed, which can realize accurate distribution of the oil output of the synchronous motor 1. The first pipeline 4 is connected to each of the nine groups of oil outlets 3. The first pipeline 4 has stable oil transmission performance, which can accurately guide the oil output from the synchronous motor 1 to the subsequent components. The first pipeline 4 is provided with a three-way valve 5 at the end away from the oil outlet 3. The three-way valve 5 is the core component of the system oil line switching, which can flexibly change the flow direction of the oil by accurate control. One outlet of the three-way valve 5 is connected to the second pipeline 6. The second pipeline 6 is connected to the oil cylinder at the end away from the three-way valve 5. The second pipeline 6 has high transmission efficiency, which can stably transport the oil to the oil cylinder, providing power support for the synchronous extension and contraction of the oil cylinder. The nine groups of oil outlets 3 uniformly distribute the oil output of the synchronous motor 1, so that multiple oil cylinders can be synchronously extended and contracted, ensuring the stability and accuracy of the mechanical equipment operation. Finally, the third pipeline 7 connected to the other outlet of the three-way valve 5 is connected to the switching system. The first pipeline 4 is connected to the second pipeline 6 and the third pipeline 7 through the three-way valve 5. The three-way valve 5 is used to switch the input of the oil from the first pipeline 4 to the second pipeline 6 or the third pipeline 7, realizing accurate control of the system on the working number of the oil cylinder. The nine groups of third pipelines 7 are collectively connected to the multi-way joint 8 at the end away from the three-way valve 5. The multi-way joint 8 has excellent shunt and flow functions, ensuring efficient transmission of the oil. The multi-way joint 8 is installed on the oil inlet pipe 2. The number of interfaces of the multi-way joint 8 corresponds to the number of the second pipelines 6, which facilitates the return of the oil in the multiple third pipelines 7 to the oil inlet pipe 2 and then to the synchronous motor 1 for uniform distribution, maintaining the stability of the system oil circulation.

[0025] Further, when reducing the number of oil cylinders, the flow path of the oil is adjusted by the three-way valve 5 to be synchronous motor 1, oil outlet 3, first pipeline 4, three-way valve 5, third pipeline 7, multi-way joint 8, oil inlet pipe 2, so that the oil is returned to the synchronous motor 1. This not only avoids the imbalance of the flow distribution of other oil outlets 3 caused by directly blocking one group of oil outlets 3, but also avoids the pressure drop caused by connecting one group of oil outlets 3 to the oil tank (the diameter of the pipeline is small, and the inner diameter of the oil tank is large, resulting in a sudden pressure drop) affecting the flow distribution of other oil outlets 3, ensuring that each oil cylinder can still obtain stable and accurate oil supply during the switching process of the number of oil cylinders, maintaining the stability of the system operation.

[0026] In this embodiment, the oil enters the synchronous motor 1 through the oil inlet pipe 2. The synchronous motor 1 uniformly distributes the oil to the nine groups of oil outlets 3 by virtue of its own characteristics.

[0027] The oil flowing out of the oil outlet 3 is transmitted to the three-way valve 5 through the first pipeline 4. The three-way valve 5 guides the oil to the second pipeline 6, which in turn delivers the oil to the oil cylinder, driving multiple oil cylinders to synchronously extend and contract.

[0028] When the number of working cylinders needs to be reduced, the three-way valve 5 is adjusted to change the direction of the oil flow. At this time, the oil flows from the first pipeline 4 to the third pipeline 7 through the three-way valve 5.

[0029] The oil in the third pipeline 7 is gathered to the multi-way joint 8, and then enters the oil inlet pipeline 2 through the multi-way joint 8, so that the oil is returned to the synchronous motor 1. In this process, the oil is evenly distributed in the synchronous motor 1 again, and the stability of the oil supply of the remaining working cylinders is maintained.

[0030] The above specific embodiments are only optional embodiments of the present application, and based on the technical solutions of the present application and the related inspirations of the above embodiments, those skilled in the art can make various alternative improvements and combinations on the above specific embodiments.
