Description

Technical Field

[0001] This utility model relates to the field of electromechanical maintenance technology, and in particular to an electromechanical positioning fixture for electromechanical maintenance. Background Technology

[0002] Electromechanical equipment refers to a general term for equipment that combines mechanical structures with electrical control systems to achieve specific functions. It encompasses industrial robots, CNC machine tools, automated production line components, motor equipment, etc., and is widely used in manufacturing, energy, transportation, and many other fields. In industrial production, the stable operation of electromechanical equipment is directly related to production efficiency and product quality; therefore, when equipment malfunctions or its performance deteriorates, timely repairs are necessary. Currently, the maintenance of electromechanical equipment is increasingly reliant on fully automated tooling. Besides the processing equipment used to perform maintenance operations, a positioning device is a core component of fully automated tooling. This positioning device not only securely locks the electromechanical equipment in place through clamping and fixing, preventing displacement during maintenance, but also moves the equipment via its own drive structure, precisely positioning the part to be repaired under the processing equipment. This allows the processing equipment to perform grinding, welding, and inspection processes, significantly improving the automation and efficiency of maintenance. However, while existing positioning devices can achieve stable clamping of electromechanical equipment, they still have shortcomings in actual maintenance processes. Positioning devices require moving equipment (such as guide rails, sliders, lead screws, and nuts) to adjust the position of the equipment. After long-term use, these moving equipment components develop tiny gaps due to wear. Simultaneously, vibrations from the processing equipment, changes in the weight distribution of the electromechanical equipment itself, and minor control errors in the drive system (such as servo motors) all contribute to unavoidable slight movements of the moving equipment during maintenance. While these slight movements may have a minor impact on the maintenance of ordinary electromechanical equipment, for high-precision equipment (such as precision instruments and sensors), they often cause the relative position of the maintenance area to deviate from the preset accuracy range, leading to maintenance failure and increased maintenance costs and time.

[0003] Based on the above viewpoints, those skilled in the art have proposed an electromechanical positioning fixture for electromechanical maintenance. Utility Model Content

[0004] The purpose of this utility model is to address the shortcomings of existing technologies by proposing an electromechanical positioning fixture for electromechanical maintenance. This fixture utilizes the characteristic of magnetorheological fluid to rapidly transform from a liquid to a near-solid state under the action of a directional magnetic field, which can form a high-strength lock on the moving platform. This effectively solves the problem that traditional positioning devices cannot simultaneously achieve both movement adjustment and stable fixation, and is suitable for the position requirements of different maintenance scenarios.

[0005] To achieve the above objectives, the present invention provides the following technical solution: An electromechanical positioning fixture for electromechanical maintenance includes a top fixing component for fixing electromechanical equipment, comprising: A vibration damping sleeve, wherein the vibration damping sleeve is annular and has an internal groove; The movable platform has an I-shaped cross-section. The lower half of the movable platform is slidably connected to the groove of the anti-vibration sleeve. A sliding sealing kit is provided on the contact surface between the lower half of the movable platform and the anti-vibration sleeve to seal the anti-vibration sleeve and the movable platform. The top fixing component is located on the top of the movable platform. A magnetic field generating device is fixedly connected to the outer peripheral surface of the vibration damping sleeve to generate a directional magnetic field on the outside of the vibration damping sleeve; A connecting bend is provided, which is connected to the interlayer between the vibration damping sleeve and the movable platform. The connecting bend is also connected to an external pump to fill the interlayer between the vibration damping sleeve and the movable platform with magnetorheological fluid.

[0006] Preferably, the magnetic field generating device includes an excitation coil wound in a ring around the outer periphery of the vibration damping sleeve and a magnetic conductive component made of a high magnetic permeability material. The excitation coil is spaced on the outer periphery of the vibration damping sleeve, and the magnetic conductive component is attached to the side of the excitation coil away from the vibration damping sleeve and at the gap of the excitation coil.

[0007] Preferably, at least two sets of driving components are installed on the lower side wall of the vibration damping sleeve, one set of driving components is arranged in the transverse direction along the bottom surface of the vibration damping sleeve, and the other set of driving components is arranged in the longitudinal direction along the ground surface of the vibration damping sleeve.

[0008] Preferably, the driving component includes a drive motor fixed to the bottom of the vibration damping sleeve and a friction ball fixed to the movable end of the drive motor, the friction ball being attached to the lower end face of the movable platform.

[0009] Preferably, a base is fixedly connected to the outer side of the lower end face of the vibration damping sleeve, and a storage pipe is fixedly connected to the center of the base. The connecting bend penetrates the outer wall of the vibration damping sleeve and communicates with the storage pipe. Several flow channel grooves communicating with the storage pipe are opened on the movable platform.

[0010] Preferably, several of the flow channels are interconnected, and their connection points extend through the bottom of the movable platform and are interconnected with the storage pipe. The difference between the inner diameter of the storage pipe and the connection point of the flow channel is greater than the difference between the outer diameter of the movable platform and the inner diameter of the anti-vibration sleeve groove.

[0011] This utility model has the following beneficial effects: 1. In this utility model, the position of the movable platform is adjusted by driving the friction ball through the driving component, which can conveniently adjust the electromechanical equipment to the target maintenance position; by utilizing the characteristic of magnetorheological fluid to quickly change from liquid to near solid under the action of a directional magnetic field, a high-strength lock can be formed on the movable platform, which effectively solves the problem that the traditional positioning device is difficult to balance movement adjustment and stable fixation, and is suitable for the position requirements of different maintenance scenarios.

[0012] 2. In this utility model, after the magnetorheological fluid is cured, it can tightly fill the gap between the anti-vibration sleeve and the moving platform, which can effectively resist the displacement of the moving platform caused by external forces during maintenance. At the same time, the properties of the magnetorheological fluid can be quickly switched by switching the magnetic field on and off, avoiding the slight displacement caused by gaps, vibrations, etc. in traditional mobile equipment, and reducing the risk of maintenance failure caused by position deviation of high-precision electromechanical equipment.

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0016] Example, refer to Figures 1-2This utility model provides an embodiment of an electromechanical positioning fixture for electromechanical maintenance, including a top fixing component 3 for fixing electromechanical equipment, comprising: a vibration damping sleeve 1, which is annular and has an internal groove; a movable platform 4, the cross-section of which is I-shaped, the lower half of which is slidably connected to the groove of the vibration damping sleeve 1, and a sliding sealing kit provided on the contact surface between the lower half of the movable platform 4 and the vibration damping sleeve 1 for sealing the vibration damping sleeve 1 and the movable platform 4; the top fixing component 3 being disposed on the top of the movable platform 4; a magnetic field generating device 2, which is fixedly connected to the outer circumferential surface of the vibration damping sleeve 1 for generating a directional magnetic field outside the vibration damping sleeve 1; and a connecting bend 8, which is connected to the interlayer between the vibration damping sleeve 1 and the movable platform 4, and is connected to an external pump for filling the interlayer between the vibration damping sleeve 1 and the movable platform 4 with magnetorheological fluid. This device utilizes the property of magnetorheological fluids to change their properties in a strong magnetic field to achieve strong fixation of the tooling. After the electromechanical equipment is fixed on the top fixing component 3, the relative position of the movable platform 4 is adjusted so that the part of the electromechanical equipment that needs maintenance is directly below the machining tooling. Then, an external pump fills the gap between the anti-vibration sleeve 1 and the movable platform 4 with magnetorheological fluid. Subsequently, the magnetic field generator 2 is activated. The directional magnetic field generated by the magnetic field generator 2 penetrates the anti-vibration sleeve 1 and acts on the magnetorheological fluid in the gap. Under the action of the strong magnetic field, the magnetic particles in the magnetorheological fluid will rapidly align themselves in an orderly manner along the direction of the magnetic field, causing it to quickly transform from its original liquid state into a solid-like state with high shear yield strength. This solid-like magnetorheological fluid... The magnetorheological fluid tightly fills the space between the anti-vibration sleeve 1 and the lower half of the movable platform 4, thereby restricting the sliding of the movable platform 4 and achieving a stable lock on the movable platform 4. This prevents the force acting on the equipment during the maintenance of the electromechanical equipment from causing displacement. When it is necessary to adjust the position of the electromechanical equipment, the magnetic field generating device is turned off, the directional strong magnetic field disappears, and the magnetic particles in the magnetorheological fluid return to a disordered state, and its properties change back to liquid. The lower half of the movable platform 4 can slide flexibly in the empty groove of the anti-vibration sleeve 1, which facilitates the adjustment of the position of the electromechanical equipment according to maintenance needs. After adjusting to the appropriate position, the magnetic field generating device 2 is restarted to re-fix it, thereby achieving flexible positioning and stable fixation of the electromechanical equipment.

[0017] Reference Figure 1 The magnetic field generating device 2 includes an excitation coil wound in a ring around the outer periphery of the vibration damping sleeve 1 and a magnetic conductive component made of a high magnetic permeability material. The gap of the excitation coil is arranged on the outer periphery of the vibration damping sleeve 1, while the magnetic conductive component is attached to the side of the excitation coil away from the vibration damping sleeve 1 and at the gap of the excitation coil.

[0018] Reference Figures 3-4At least two sets of driving components 6 are installed on the lower side wall of the vibration damping sleeve 1. One set of driving components 6 is arranged in the transverse direction along the bottom surface of the vibration damping sleeve 1, while the other set of driving components 6 is arranged in the longitudinal direction along the ground surface of the vibration damping sleeve 1. The two sets of driving components 6 enable adjustment of the vibration damping sleeve 1 in the transverse and longitudinal directions, thereby ensuring that the electromechanical equipment fixed on the top fixing assembly 3 can be accurately moved to the bottom of the processing equipment. The driving component 6 includes a drive motor 61 fixed to the bottom of the vibration damping sleeve 1 and a friction ball 62 fixed to the movable end of the drive motor 61. The friction ball 62 is in contact with the lower end surface of the movable platform 4. The driving component 6 adjusts the overall position of the movable platform 4 through the friction between the friction ball 62 and the bottom surface of the movable platform 4. When the drive motor 61 drives the friction ball 62 to rotate, the friction ball 62 drives the movable platform 4 to make relevant adjustments through friction. When the equipment moves to the bottom of the processing equipment, the drive motor 61 can be stopped. It should be noted that the processing equipment is usually equipped with a vision system, which is used to capture the processing equipment and ensure that the position of the electromechanical equipment that needs maintenance falls within the processing range of the processing equipment.

[0019] Reference Figures 2-3 and Figure 5 A base 5 is fixedly connected to the outer side of the lower end face of the vibration damping sleeve 1. A storage pipe 7 is fixedly connected to the center of the base 5. A connecting bend 8 penetrates the outer wall of the vibration damping sleeve 1 and communicates with the storage pipe 7. Several flow channels 9 connected to the storage pipe 7 are opened on the movable platform 4. Magnetorheological fluid is poured into the storage pipe 7 through the connecting bend 8. The magnetorheological fluid eventually flows into the interlayer between the vibration damping sleeve 1 and the movable platform 4 through the flow channels 9. The several flow channels 9 are interconnected, and their connection points penetrate the bottom of the movable platform 4 and communicate with the storage pipe 7. The difference between the inner diameter of the storage pipe 7 and the connection point of the flow channel 9 is greater than the difference between the outer diameter of the movable platform 4 and the inner diameter of the empty groove of the vibration damping sleeve 1. This prevents the groove at the bottom of the movable platform 4 from exceeding the range of the storage pipe 7 when the movable platform 4 moves, thus preventing the magnetorheological fluid from leaking.

[0020] Working Principle: This device utilizes the property of magnetorheological fluid to change its properties in a strong magnetic field to achieve strong fixation of the tooling. After the electromechanical equipment is fixed on the top fixing component 3, the drive component 6 adjusts the overall position of the movable platform 4 through the friction between the friction ball 62 and the bottom surface of the movable platform 4. When the drive motor 61 drives the friction ball 62 to rotate, the friction ball 62 drives the movable platform 4 to make relevant adjustments through friction. When the equipment moves to the bottom of the processing equipment, the drive motor 61 can be stopped. Subsequently, the external pump fills the gap between the vibration damping sleeve 1 and the movable platform 4 with magnetorheological fluid, and the magnetic field generator 2 is activated. The directional magnetic field generated by the magnetic field generator 2 penetrates the vibration damping sleeve 1 and acts on the magnetorheological fluid in the gap. Under the action of the strong magnetic field, the magnetic particles in the magnetorheological fluid will rapidly move along the direction of the magnetic field. The magnetorheological fluid is arranged in a specific order, rapidly transforming it from a liquid state into a solid-like state with high shear yield strength. This solid-like magnetorheological fluid tightly fills the space between the vibration-damping sleeve 1 and the lower half of the movable platform 4, thereby restricting the sliding of the movable platform 4 and achieving a stable lock on the movable platform 4. This prevents the force acting on the equipment during maintenance from causing displacement. When the position of the equipment needs to be adjusted, the magnetic field generator is turned off, the directional strong magnetic field disappears, and the magnetic particles in the magnetorheological fluid return to a disordered state, reverting to a liquid state. The lower half of the movable platform 4 can then slide flexibly within the empty groove of the vibration-damping sleeve 1, facilitating the adjustment of the equipment's position according to maintenance needs. Once adjusted to the appropriate position, the magnetic field generator 2 is restarted to re-fix the equipment, thus achieving flexible positioning and stable fixation of the equipment.

[0021] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
