Technical Field
[0001] This utility model belongs to the field of electro-hydraulic servo technology, and in particular relates to an electro-hydraulic servo multi-channel coordinated loading system. Background Technology
[0002] An electro-hydraulic servo system is an application example of an electro-hydraulic servo actuator. It is a hydraulic actuator that converts hydraulic energy from a hydraulic source into mechanical energy. It can also be servo controlled by the product's built-in displacement sensor or limit switch as needed. The electro-hydraulic servo actuator is used to execute commands from the main controller to control the speed, direction, displacement, and force of the load, while simultaneously feeding back signals to the main controller. It features high output force, accurate operating position, and small size, and has been widely used in industries such as aviation, power generation, steelmaking, automobiles, shipbuilding, and materials testing.
[0003] Common electro-hydraulic servo actuators require external hoisting equipment for mechanical testing. This hoisting process can easily cause significant bending and torsional deformation, affecting their operation. Furthermore, during oil supply, mutual interference can occur, further impacting the accuracy of the actuators. To address these issues, we provide an electro-hydraulic servo multi-channel coordinated loading system. Utility Model Content

Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.
[0023] For a specific implementation example, please refer to Implementation Example 1. Figure 1-8 This utility model is an electro-hydraulic servo multi-channel coordinated loading system, including a support base mechanism 1. The support base mechanism 1 includes several metal splicing bases 11. A splicing locking component 12 is fixedly connected to one side of each metal splicing base 11. The metal splicing bases 11 are connected to each other through the splicing locking component 12 to form a metal operating base. Two electro-hydraulic servo components 2 are symmetrically clamped on the upper part of the support base mechanism 1. The electro-hydraulic servo components 2 are clamped and engaged with the metal splicing bases 11. The electro-hydraulic servo components 2 include several fixedly arranged servo actuators 201. The movement of the servo actuators 201 is controlled by an external control system. A channel oil distribution structure 3 is fixedly arranged on one side of the support base mechanism 1. The channel oil distribution structure 3 includes four sets of fixedly arranged channel oil distribution components 31. The channel oil distribution components 31 include a fixedly arranged one-to-two oil distributor 311.
[0024] The operation process of this embodiment is as follows: Before use, select an appropriate number of metal splicing bases 11 according to the operation requirements, and use the splicing locking assembly 12 to splice the metal splicing bases 11 to form a metal operating base. The electro-hydraulic servo assembly 2 is snapped and fixedly installed on the upper surface of the metal operating base to limit the position of the servo actuator 201. At the same time, the external control system controls the servo actuator 201. The servo actuator 201 moves and performs mechanical testing on the equipment to be tested. During the mechanical testing, the one-to-two oil distributor 311 is used to supply oil to the two servo actuators 201 respectively. The one-to-two oil distributor 311 is an isolation type to ensure that the servo actuators 201 do not interfere with each other.
[0025] For a specific embodiment two, please refer to Figure 1-8 Based on the specific embodiment 1, specifically, the upper surface of the metal splicing base 11 is provided with several adjustable mounting grooves, and the splicing locking assembly 12 includes a splicing control seat 121 fixedly connected to one side of the metal splicing base 11. One side of the splicing control seat 121 is provided with an adjustable slide, which is connected to the interior of the splicing control seat 121. A splicing locking ring 122 is rotatably provided inside the splicing control seat 121. The splicing locking ring 122 is rotatably connected to the metal splicing base 11, and a splicing adjustment rod 123 is fixedly connected to the periphery of the splicing locking ring 122. The splicing adjustment rod 123 is located inside the adjustable slide.
[0026] Furthermore, the electro-hydraulic servo assembly 2 also includes two longitudinal support frames 202 symmetrically engaged above the metal splicing base 11 and an adjustment support platform 203 engaged above the metal splicing base 11. A transverse support frame 204 is fixedly connected between the two longitudinal support frames 202, and two adjustment support seats 205 are symmetrically slidably arranged on the surface of the transverse support frame 204. Two servo actuator cylinders 201 are fixedly installed on the lower surface of the adjustment support seat 205, one servo actuator cylinder 201 is fixedly installed on an inner side of the longitudinal support frame 202, and the other servo actuator cylinder 201 is fixedly installed on a side of the adjustment support platform 203 near the longitudinal support frame 202.
[0027] Furthermore, the channel oil distribution assembly 31 also includes a fixedly installed channel support frame 312. A channel support seat 313 is fixedly installed at the bottom of the channel support frame 312. One side of the channel support seat 313 is connected to the servo actuator cylinder 201 through a pipeline system. A one-to-two oil distributor 311 is fixedly installed on the upper surface of the channel support seat 313. The one-to-two oil distributor 311 has a one-inlet and two-outlet structure, which can supply oil to two sets of actuators respectively. The one-to-two oil distributor 311 is an isolation type, which can ensure that the oil circuits of each actuator do not interfere with each other. The one-to-two oil distributor 311 has its own high pressure, low pressure and cut-off functions, is electrically operated, and can completely isolate the oil circuits of the controlled actuators through the control system to avoid pressure interference between channels.
[0028] The operation process of this embodiment is as follows: Before use, select an appropriate number of metal splicing bases 11 according to operational needs. Use the splicing locking assembly 12 to splice the metal splicing bases 11. During splicing, manually rotate the splicing adjustment rods 123 on the sides of the two metal splicing bases 11 simultaneously. The splicing adjustment rods 123 drive the splicing locking ring 122 to rotate until the splicing locking ring 122 rotates into the interior of the adjacent splicing control seat 121. This realizes the splicing operation between two adjacent metal splicing bases 11. The splicing between the metal splicing bases 11 is achieved through the mutual cooperation between the splicing locking assemblies 12. The metal splicing bases 11 are spliced together to form a shape. A metal operating base is formed, and the longitudinal support frame 202 and the adjustment support platform 203 are respectively inserted into the adjustment and installation groove on the upper surface of the metal splicing base 11. This enables the electro-hydraulic servo component 2 to be locked and fixed on the upper surface of the metal operating base, thereby limiting the position of the servo actuator 201. At the same time, the servo actuator 201 is controlled by an external control system. The servo actuator 201 moves and performs mechanical testing on the equipment to be tested. During the mechanical testing, a one-to-two oil distributor 311 is used to supply oil to the two servo actuators 201 respectively. The one-to-two oil distributor 311 is an isolation type to ensure that the servo actuators 201 do not interfere with each other.
