Description

Technical Field

[0001] This utility model relates to the field of mechanical engineering technology, specifically to a flexible rotor vibration test bench balance disc assembly that is easy to assemble and disassemble. Background Technology

[0002] The balance disc assembly of a flexible rotor vibration test bench is a crucial component used to adjust the balance of the flexible rotor. In some dynamic balancing test benches, a compensation disc is chosen as the balancing plane. By adding a balancing mass to the compensation disc, the amount of balancing material to be added to the specimen's balancing surface can be calculated based on the force system equilibrium conditions. During operation, a trial mass is first added to the compensation disc and adjusted to minimize the vibration of the pendulum. Then, the balancing mass is transferred from the compensation disc to the specimen's balancing surface to achieve dynamic balance of the flexible rotor. In the field of flexible rotor vibration testing, the ease of assembly and disassembly of the balance disc assembly is crucial. In the existing technology, the common practice to make the balance disc assembly easy to assemble and disassemble is to set multiple elastic clamps on its outside for fixation. However, this method has obvious drawbacks. Since multiple elastic clamps are distributed in different positions, the operator needs to adjust the clamps one by one from each position during operation. The operation is cumbersome and time-consuming, which greatly reduces work efficiency and makes it difficult to meet the requirements of high-efficiency testing. Therefore, a flexible rotor vibration test bench balance disc assembly that is easy to disassemble and assemble is proposed to address the above problems. Utility Model Content

[0004] To achieve the above objectives, this utility model provides the following technical solution: A flexible rotor vibration test bench balance disk assembly for easy assembly and disassembly includes a balance disk body. A main limiting hole is provided on one side of the balance disk body, and auxiliary limiting holes are provided at both the top and bottom ends of the balance disk body. An active limiting mechanism is installed inside the main limiting hole, and an auxiliary limiting mechanism is installed inside the auxiliary limiting holes. A connecting sleeve is fixed at the center inside the balance disk body. The active limiting mechanism includes a threaded sleeve, one end of which is slidably connected to a sliding element. A return spring is fitted on the outer side of the threaded sleeve. Connecting arms are fixed on both sides of the sliding element, and a connecting wheel is fixed at one end of each connecting arm. The auxiliary limiting mechanism includes a support base, the top of which is fixedly mounted with a sliding seat. A sliding shaft is slidably connected to the inner side of the sliding seat, extending to the outside of the sliding seat. A limiting pin mechanism is fixedly connected to the outside of the sliding shaft, and a connecting arm is fixed to the side of the limiting pin mechanism near the connecting wheel. The connecting arm and the connecting wheel are in sliding engagement.

[0005] As a further optimization of this utility model, the connecting arm has an inclined structure, and the surface of the connecting arm has multiple linearly arranged oil injection grooves.

[0006] As a further optimization of this utility model, the limiting pin mechanism includes a limiting pin body, the top of which is provided with an anti-slip groove, the vertical projection shape of which is C-shaped, and the bottom of which is provided with an oil injection hole near the connecting arm, the interior of which is connected to the interior of the limiting pin body.

[0007] As a further optimization of this utility model, the limiting pin body is slidably disposed between the sliding seat and the support seat, the limiting pin body is located inside the auxiliary limiting hole, and the center of the limiting pin body and the center of the sliding seat are located on the same central axis.

[0008] As a further optimization of this utility model, the two support seats are symmetrically distributed from left to right, the outer side of the support seat is fixedly connected to the inner side of the balance disc body, and one end of the support seat is fixedly connected to the outer side of the connecting sleeve.

[0009] As a further optimization of this utility model, the sliding seat and the connecting sleeve are fixedly connected, and both sides of the sliding seat are provided with fitting grooves for fitting the sliding shaft. The fitting grooves are parallel to each other and the sliding seat is slidably engaged with the sliding shaft.

[0010] As a further optimization of this utility model, the following features are provided: the screw sleeve is fixedly disposed inside the main limiting hole; the interior of the sliding member is connected to the interior of the screw sleeve; one end of the return spring is fixedly connected to the front end of the sliding member; and the other end of the return spring is fixedly connected to the inner wall of the balance disc body.

[0011] Compared with the prior art, the beneficial effects of this utility model are: In this utility model, by linking the active limiting mechanism and the auxiliary limiting mechanism, only the screw at the main limiting hole needs to be turned to drive the limiting pin mechanism to limit in multiple directions synchronously, which greatly simplifies the operation steps, improves the disassembly and assembly efficiency, and meets the needs of high-efficiency testing. At the same time, the oil injection structure reduces component wear, and the anti-slip design enhances the limiting stability, ensuring the long-term reliable operation of the components, taking into account both convenience and practicality.

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.

[0015] It should be noted that the terminology used herein is for the purpose of describing particular embodiments only and is not intended to limit the exemplary embodiments according to this application. As used herein, the singular form is intended to include the plural form as well, unless the context clearly indicates otherwise. Furthermore, it should be understood that when the terms "comprising" and / or "including" are used in this specification, they indicate the presence of features, steps, operations, devices, components, and / or combinations thereof.

[0016] Please see Figures 1-6 This utility model provides a technical solution: The flexible rotor vibration test bench balance plate assembly, which is easy to assemble and disassemble, includes a balance plate body 1. A main limiting hole 2 is provided on one side of the balance plate body 1, and auxiliary limiting holes 3 are provided at both the top and bottom ends of the balance plate body 1. An active limiting mechanism 4 is installed inside the main limiting hole 2, and an auxiliary limiting mechanism 5 is installed inside the auxiliary limiting holes 3. A connecting sleeve 6 is fixed at the center inside the balance plate body 1, and a bearing that cooperates with the rotation of the flexible rotor is installed inside the connecting sleeve 6. The active limiting mechanism 4 includes a threaded sleeve 41, one end of which is slidably connected to a sliding element 42. A return spring 43 is sleeved on the outer side of the sliding member 42. Connecting arms 44 are fixed on both sides of the sliding member 42, and a connecting wheel 45 is fixed at one end of the connecting arm 44. The auxiliary limiting mechanism 5 includes a support base 51. A sliding base 52 is fixedly installed on the top of the support base 51. A sliding shaft 53 is slidably connected to the inner side of the sliding base 52. The sliding shaft 53 extends to the outside of the sliding base 52. A limiting pin mechanism 55 is fixedly connected to the outside of the sliding shaft 53. A connecting arm 56 is fixed on the side of the limiting pin mechanism 55 near the connecting wheel 45. The connecting arm 56 and the connecting wheel 45 are in sliding engagement.

[0017] Specifically, the main limiting hole 2 and the auxiliary limiting hole 3 on the balance disc body 1 are respectively installed with the active limiting mechanism 4 and the auxiliary limiting mechanism 5, providing a structural basis for convenient disassembly and assembly. The active limiting mechanism 4 has a screw sleeve 41, a sliding part 42, a return spring 43, etc. working together to achieve initial limiting drive through screw drive. The auxiliary limiting mechanism 5 has a support seat 51, a sliding seat 52, etc. working with the connecting wheel 45 and the connecting arm 56 of the active limiting mechanism 4 to transmit and convert the driving force of active limiting, creating conditions for multi-directional limiting fixation and convenient disassembly and assembly, solving the problem of cumbersome disassembly and assembly of traditional multi-elastic clamps, and improving work efficiency. As a further implementation of this solution, the connecting arm 56 has an inclined structure, and the surface of the connecting arm 56 is provided with multiple linearly arranged oil injection grooves 57. Specifically, when the connecting wheel 45 pushes the connecting arm 56, the inclined structure can more efficiently convert the horizontal driving force into a force that moves the limiting pin mechanism 55 toward the auxiliary limiting hole 3, allowing the limiting pin mechanism 55 to extend more smoothly out of the auxiliary limiting hole 3 to achieve limiting. At the same time, the multiple linearly arranged oil grooves 57 on the surface facilitate the retention of lubricating oil and its flow into the contact surface between the connecting wheel 45 and the connecting arm 56, reducing friction and wear between the two, extending the service life of the components, ensuring the long-term stability of the components, and achieving convenient disassembly and assembly functions. As a further implementation of this solution, the limiting pin mechanism 55 includes a limiting pin body 551. The top of the limiting pin body 551 is provided with an anti-slip groove 552. The vertical projection shape of the limiting pin body 551 is C-shaped. The bottom of the limiting pin body 551 near the connecting arm 56 is provided with an oil injection hole 553. The interior of the oil injection hole 553 is connected to the interior of the limiting pin body 551. The limiting pin body 551 is slidably disposed between the sliding seat 52 and the support seat 51. The limiting pin body 551 is located inside the auxiliary limiting hole 3. The center of the limiting pin body 551 and the center of the sliding seat 52 are located on the same central axis. Specifically, this structural design ensures the stability of the movement trajectory of the limit pin body 551 during the sliding process, enabling it to accurately extend into or out of the auxiliary limit hole 3, ensuring the accuracy and reliability of the bearing seat limit, and also allowing the driving force transmitted by the active limit mechanism 4 to more effectively drive the movement of the limit pin body 551, improving the smoothness and efficiency of the disassembly and assembly process. As a further implementation of this solution, the two support seats 51 are symmetrically distributed from left to right. The outer side of the support seat 51 is fixedly connected to the inner side of the balance disc body 1, and one end of the support seat 51 is fixedly connected to the outer side of the connecting sleeve 6. This layout allows the support seats 51 to provide stable support for components such as the sliding seat 52 from both sides, enhancing the overall structural stability of the auxiliary limiting mechanism 5. This makes the cooperation between the active limiting mechanism 4 and the auxiliary limiting mechanism 5 more stable. During disassembly and assembly, it can transmit force and achieve limiting more reliably, ensuring the convenience and stability of disassembly and assembly of the balance disc assembly, and avoiding disassembly and assembly difficulties or limiting failure due to unstable support. As a further implementation of this solution, the sliding seat 52 is fixedly connected to the connecting sleeve 6. Both sides of the sliding seat 52 are provided with matching grooves 58 for matching the sliding shaft 53. The matching grooves 58 and the sliding seat 52 are parallel to each other, and the matching grooves 58 and the sliding shaft 53 are slidably engaged, providing a precise track for the sliding of the sliding shaft 53. This makes the sliding shaft 53 drive the limiting pin mechanism 55 to move more smoothly and accurately, ensuring that the limiting pin mechanism 55 can accurately respond to the driving force of the active limiting mechanism 4 and smoothly realize the action of extending into or out of the auxiliary limiting hole 3. This improves the working accuracy and stability of the auxiliary limiting mechanism 5 and further ensures the convenience of disassembly and assembly of the balance disc assembly. As a further implementation of this solution, the screw sleeve 41 is fixedly installed inside the main limiting hole 2, the interior of the sliding member 42 is connected to the interior of the screw sleeve 41, one end of the return spring 43 is fixedly connected to the front end of the sliding member 42, and the other end of the return spring 43 is fixedly connected to the inner wall of the balance disc body 1. This structure allows the screw to be screwed into the screw sleeve 41, which can smoothly squeeze the sliding member 42 to move, thereby driving the connecting wheel 45 and other components to move, realizing active limiting drive; when the screw is screwed out, the return spring 43 can pull the sliding member 42 to automatically reset, preparing for the next disassembly and assembly, making the driving and reset process of the active limiting mechanism 4 smoother and more automated, greatly improving the convenience of disassembly and assembly of the balance disc assembly, and solving the trouble of manual reset required for traditional disassembly and assembly; Work process: Place the balance disc body 1 in a suitable position, ensuring that the connecting sleeve 6 corresponds to the installation position of the flexible rotor, and at the same time ensure that the main limiting hole 2 and the auxiliary limiting hole 3 are in an operable state. Screw the bearing seat screw into the screw sleeve 41 through the main limiting hole 2. As the screw goes deeper, one end of the screw extends into the sliding member 42 and squeezes the sliding member 42 to move away from the screw sleeve 41. At this time, the return spring 43 sleeved on the outside of the screw sleeve 41 is stretched. When the sliding member 42 moves, it drives the connecting arms 44 on both sides to move synchronously. The connecting arms 44 then drive the connecting wheel 45 to move. During the movement of the connecting wheel 45, it slides into contact with the inclined connecting arm 56. As the sliding member 42 continues to penetrate deeper, the connecting wheel 45 pushes the connecting arm 56 closer to the auxiliary limiting hole 3. The movement of the connecting arm 56 drives the limiting pin body 551 of the limiting pin mechanism 55 to move along the path between the sliding seat 52 and the support seat 51, and finally extends into the outside of the auxiliary limiting hole 3. Through the anti-slip groove 552 at the top of the limiting pin body 551, it makes close contact with the mounting cavity of the bearing seat, achieving a multi-directional limiting and fixing effect. During this process, the support seat 51 plays the role of stabilizing and supporting the sliding seat 52 and improving the internal support force of the balance disc body 1. To reduce wear between the connecting wheel 45 and the connecting arm 56 and extend their service life, lubricating oil can be added to the inside of the limiting pin body 551 through the auxiliary limiting hole 3. The lubricating oil is discharged from the oil injection hole 553 through the inner side of the limiting pin body 551 and flows into the oil injection groove 57 of the connecting arm 56 through the oil injection hole 553. The lubricating oil then flows into the contact surface between the connecting wheel 45 and the connecting arm 56 through the oil injection groove 57 to achieve lubrication and maintenance. During disassembly, the screw is turned in the opposite direction, causing it to gradually move away from the inside of the sleeve 41 and the sliding member 42. Since the sliding member 42 is no longer limited by the screw, it automatically resets under the tension of the return spring 43. At the same time, the connecting wheel 45 no longer applies pressure to the connecting arm 56. At this time, under the action of the retraction spring 54, the limiting pin mechanism 55 is driven away from the auxiliary limiting hole 3 through the sliding shaft 53 connected to the limiting pin mechanism 55, thus releasing the limitation on the bearing seat and allowing the balance disc assembly to be disassembled.

[0018] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
