Description

Technical Field

[0001] This invention relates to the field of servo drive technology, and in particular to a high-efficiency and energy-saving servo drive for an oil pump hydraulic system. Background Technology

[0002] The hydraulic pump system and servo drive are core components combining precision transmission and intelligent control. They achieve precise control of hydraulic energy by using a servo motor to drive the pump. In a servo hydraulic system, the servo drive acts as the control core, receiving position, speed, or torque commands to precisely adjust the speed and torque of the servo motor, thereby driving the pump (such as a gear pump or piston pump) to generate hydraulic energy. The pump then transmits this hydraulic energy to the hydraulic cylinder or motor, driving the actuator to complete linear or rotary motion. This combination achieves high precision, high response speed, and energy-saving control in hydraulic systems, and is widely used in CNC machine tools, industrial robots, injection molding machines, and other fields.

[0003] However, when the control module within an existing servo drive malfunctions and requires repair, maintenance personnel typically need to open the cabinet and reach inside to perform the repair work, increasing the complexity and time cost of maintenance. Furthermore, the installation and removal process of the control module is complex and inefficient, failing to meet the demands of modern industry for rapid repair.

[0004] To address the aforementioned issues, we propose a highly efficient and energy-saving servo drive for oil pump hydraulic systems. Summary of the Invention

[0005] The purpose of this invention is to solve the problems in the background art by proposing a high-efficiency and energy-saving servo drive for oil pump hydraulic systems.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a high-efficiency and energy-saving servo drive for an oil pump hydraulic system, comprising:

[0007] The upper part of the shell is open, and heat dissipation vents are provided on both sides of the shell; The top cover is movably installed on the top of the housing. A lifting plate is fixed to the lower side of the top cover via a component plate and is slidably connected to the housing. Multiple control modules are detachably installed on the surface of the component plate. The lifting assembly includes a drive motor fixed to the bottom of the housing, a lead screw fixed to the drive end of the drive motor, which passes through the bottom of the lifting plate, and a nut threaded onto the surface of the lead screw, which is fixedly inserted through the bottom of the lifting plate. The disassembly and assembly assembly is used to disassemble the control module and install it onto the surface of the component board; The dust filter assembly is detachably installed between the top cover and the lifting plate; The heat dissipation component is detachably installed between the top cover and the lifting plate.

[0008] In the aforementioned high-efficiency and energy-saving oil pump hydraulic system servo drive, the disassembly and assembly assembly includes a screw fixed between the top cover and the lifting plate. The screw has multiple threaded tubes threaded onto its surface. Each threaded tube has an assembly plate fixedly fitted onto its surface. Each assembly plate has multiple mounting slots on its upper and lower sides, which match the control module.

[0009] In the aforementioned high-efficiency and energy-saving oil pump hydraulic system servo drive, the dust filter assembly includes fixed frames respectively placed on both sides of the assembly plate, and filter screens are fixed in both fixed frames. The top cover and the lifting plate have insertion slots at both ends, which are interference fit with the fixed frames.

[0010] In the aforementioned high-efficiency and energy-saving servo drive for an oil pump hydraulic system, the heat dissipation component includes a connecting plate located on the side of the component board away from the control module. A cooling fan is mounted on the surface of the connecting plate, and the ends of the two plug slots are provided with connecting slots, which are located on the side of the component board away from the control module and are interference-fitted with the connecting plate.

[0011] In the aforementioned high-efficiency and energy-saving oil pump hydraulic system servo drive, the component plate is made of a thermally conductive material, and its surface has multiple heat dissipation holes.

[0012] In the aforementioned high-efficiency and energy-saving oil pump hydraulic system servo drive, each of the threaded tubes has two knobs fixedly fitted onto its surface, which are respectively attached to the upper and lower sides of the corresponding assembly plate.

[0013] In the aforementioned high-efficiency and energy-saving oil pump hydraulic system servo drive, the end of each assembly plate is slidably attached to the surface of the component plate.

[0014] In the aforementioned high-efficiency and energy-saving oil pump hydraulic system servo drive, the connecting plate has limit plates fixed at both ends on the side away from the component plate, and its other end is in contact with the corresponding fixing frame. Both fixing frames are slidably attached to the inner surface of the housing and correspond to the two heat dissipation ports respectively.

[0015] Compared with existing technologies, the advantages of this high-efficiency and energy-saving servo drive for oil pump hydraulic systems are as follows: 1. The lifting components enable rapid lifting of the control module, facilitating maintenance personnel to perform maintenance work outside the casing. This significantly reduces the complexity and time cost of maintenance, greatly improves maintenance efficiency, and also reduces potential safety risks during the maintenance process.

[0016] 2. The design of the disassembly and assembly components allows maintenance personnel to simply rotate the control module to fix or release it without the need for additional tools, greatly simplifying the operation process. Especially in emergency situations, it enables a quick response and problem-solving.

[0017] 3. The combination of heat dissipation and dust filtration components not only effectively improves the heat dissipation performance of the servo drive but also prevents dust from entering the housing, extending the equipment's lifespan. The cooling fan features a low-noise design, ensuring effective heat dissipation while reducing noise pollution during operation, thus improving the comfort of the working environment. The filter uses a high-density material to effectively filter fine particles in the air, preventing dust from adhering to electronic components and avoiding equipment malfunctions caused by poor heat dissipation.

[0018] 4. The sliding fit design between the fixed frame and the inner surface of the housing ensures the stability of the dust filter and heat dissipation components, while facilitating disassembly and replacement, thus improving overall maintainability.

[0019] In summary, this invention, through the collaborative design of multiple components, successfully solves the shortcomings of traditional servo drives in terms of maintenance complexity, heat dissipation performance, and dustproof capability, providing a more reliable guarantee for the efficient operation of oil pump hydraulic systems.

[0022] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0023] Reference Figures 1 to 6 A high-efficiency and energy-saving servo drive for an oil pump hydraulic system, comprising: The upper part of the shell 1 is open, and heat dissipation vents 3 are provided on both sides of the shell 1; The top cover 2 is movably installed on the top of the housing 1. The lower side of the top cover 2 is fixed with a lifting plate 5 through the component plate 4, which is slidably connected to the housing 1. Multiple control modules 6 are detachably installed on the surface of the component plate 4. The component plate 4 is made of thermally conductive material and has multiple heat dissipation holes 22 on its surface, which can effectively increase air circulation and thus improve heat dissipation efficiency. In addition, the thermally conductive material of the component plate 4 further ensures that heat can be quickly transferred from the inside to the external environment to avoid overheating of the equipment.

[0024] The lifting assembly includes a drive motor 7 fixed to the bottom of the housing 1. A lead screw 8 is fixed to the drive end of the drive motor 7 and passes through the bottom of the lifting plate 5. A nut 9 is threaded onto the surface of the lead screw 8 and is fixedly passed through the bottom of the lifting plate 5. When the drive motor 7 is running, it drives the lead screw 8 to rotate. Since the nut 9 is fixed on the lifting plate 5, the rotation of the lead screw 8 is converted into the up and down movement of the lifting plate 5.

[0025] The disassembly and assembly assembly is used to disassemble and install the control module 6 onto the surface of the component plate 4. The disassembly and assembly assembly includes a screw 10 fixed between the top cover 2 and the lifting plate 5. The surface of the screw 10 is threaded with multiple threaded tubes 11. Each threaded tube 11 is fixedly fitted with an assembly plate 12. Each assembly plate 12 has multiple mounting slots 14 on its upper and lower sides, which match the control module 6. The design of the mounting slots 14 allows the control module 6 to be firmly embedded in them, ensuring that it will not loosen or shift during use. The assembly plate 12 achieves a flexible height adjustment function through the cooperation of the threaded tubes 11 and the screw 10, thereby adapting to component plates 4 of different thicknesses.

[0026] The dust filter assembly is detachably installed between the top cover 2 and the lifting plate 5. The dust filter assembly includes fixed frames 15 placed on both sides of the assembly plate 4. Each fixed frame 15 has a filter screen 16 fixed inside. The top cover 2 and the lifting plate 5 have insertion slots 17 on opposite sides, which are interference fit with the fixed frames 15. The fixed frames 15 are tightly connected to the top cover 2 and the lifting plate 5 through the insertion slots 17, ensuring that the filter screen 16 can effectively block dust from entering the housing 1. In addition, the sliding fit structure of the fixed frames 15 makes it more convenient to install and disassemble, and the operation can be completed without additional tools. This design not only improves the dustproof performance of the equipment, but also further enhances the overall maintainability, providing a guarantee for the long-term stable operation of the equipment.

[0027] The heat dissipation component is detachably installed between the top cover 2 and the lifting plate 5. The heat dissipation component includes a connecting plate 18 located on the side of the component plate 4 away from the control module 6. A cooling fan 19 is installed on the surface of the connecting plate 18. The ends of the two plug slots 17 are provided with connecting slots 20, which are located on the side of the component plate 4 away from the control module 6 and are interference-fitted with the connecting plate 18. The connecting plate 18 is tightly connected to the top cover 2 and the lifting plate 5 through the connecting slots 20 to ensure that the cooling fan 19 remains stable during operation. The cooling fan 19 is driven by a high-efficiency motor and can provide strong airflow with low power consumption, further improving the heat dissipation effect.

[0028] Specifically, each threaded tube 11 has two knobs 13 fixedly fitted onto its surface, which are respectively attached to the upper and lower sides of the corresponding assembly plate 12. The design of the knobs 13 makes it easy for users to manually adjust the position of the assembly plate 4, thereby realizing the installation and disassembly of the control module 6.

[0029] Specifically, the end of each assembly plate 12 is slidably attached to the surface of the component plate 4, which serves to limit the assembly plate 4 and ensure its axial movement.

[0030] Specifically, the connecting plate 18 has two fixed limiting plates 21 on the side away from the component plate 4, and the other end of the connecting plate 18 is in contact with the corresponding fixing frame 15. Both fixing frames 15 are slidably attached to the inner surface of the housing 1 and correspond to the two heat dissipation ports 3 respectively. The limiting plates 21 are used to fix the position of the cooling fan 19 to prevent it from shifting or loosening during the operation of the equipment, thereby improving the reliability of the overall structure.

[0031] The working principle of this invention is as follows: When in use, when it is necessary to repair the control module 6 inside the housing 1, first start the drive motor 7 to drive the lead screw 8 to rotate. The nut 9 threaded on the surface of the lead screw 8 will then push the lifting plate 5 to move up and down until the component board 4 and each control module 6 are moved out of the housing 1. Next, pull out the fixing frame 15 in front of the control module 6 to expose the control module 6, so that the maintenance personnel can perform maintenance. When it is necessary to disassemble the corresponding control module 6, simply rotate the corresponding knob 13 manually to separate the threaded tube 11 from the screw 10, and then remove the assembly plate 12 from the surface of the component plate 4 to easily complete the disassembly operation of the control module 6. During reinstallation, align the assembly plate 12 with the mounting slot 14 on the component plate 4, and fix the position using the knob 13 to ensure that the control module 6 is securely embedded in the slot and avoids loosening. In addition, after the equipment has been running for a long time, the dust filter assembly may accumulate a lot of dust. At this time, the fixing frame 15 can be directly pulled out from the insertion slot 17, the filter screen 16 can be replaced or cleaned, and then reinserted. The operation is simple and quick and does not require any tools. After the equipment is started, the cooling fan 19 begins to run, creating air convection through the heat dissipation holes 22 on the component plate 4 and the heat dissipation vents 3 on both sides of the housing 1, effectively reducing the internal temperature. At the same time, the filter 16 prevents external dust from entering, ensuring the cleanliness of the equipment's interior.

[0032] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention in any way. Those skilled in the art can readily implement the present invention based on the accompanying drawings and the above description. However, any modifications, alterations, or variations made by those skilled in the art without departing from the scope of the present invention, utilizing the disclosed technical content, are equivalent embodiments of the present invention. Furthermore, any modifications, alterations, or variations made to the above embodiments based on the essential technology of the present invention are still within the protection scope of the present invention.
