Description

Technical Field

[0001] This application relates to the technical field of cross-flow fan processing equipment, and in particular to a synchronization mechanism for a multi-station cross-flow fan impeller dynamic balancing device. Background Technology

[0002] Cross-flow fan impellers, as a common aerodynamic component, are typically multi-bladed elongated cylindrical bodies with forward-curving multi-airfoil blades. When the impeller rotates, airflow enters from one end of the impeller's blade cascade, passes through the impeller's interior, and exits from the other end of the impeller's blade cascade into the volute, forming the working airflow. To ensure smooth fan operation and low noise, the cross-flow fan impeller needs dynamic balancing testing and correction.

[0003] In the existing technology, a dynamic balancing and deformation correction integrated machine is often used to process the impeller of the cross-flow fan. The machine body has multiple stations to complete the feeding, dynamic balancing detection, imbalance correction and unloading processes in sequence. In order to reduce mutual interference between stations during the detection and correction process, the existing equipment usually designs the stations as independent structures and can disconnect them during operation.

[0004] However, when it is necessary to adapt to impellers of different sizes of cross-flow fans, the independent station structure faces adjustment difficulties: in order to adapt to impellers of different lengths, the position of each station needs to be adjusted individually; after the adjustment is completed, the relative positional relationship between the stations also needs to be recalibrated to ensure the concentricity and straightness of the process. Therefore, the independent adjustment process is complicated, the calibration accuracy is difficult to maintain, and the adjustment efficiency is low. Utility Model Content

[0005] To address the issue of low adjustment efficiency in existing balancing equipment, this application provides a synchronization mechanism for a multi-station cross-flow fan impeller dynamic balancing device.

[0006] The synchronization mechanism of the multi-station cross-flow fan impeller dynamic balancing equipment provided in this application adopts the following technical solution: A synchronization mechanism for a multi-station cross-flow fan impeller dynamic balancing device includes: The drive assembly includes a motor and a synchronizing rod, wherein the output shaft of the motor is detachably connected to the synchronizing rod via a coupling, and the motor is used to drive the synchronizing rod to rotate about the shaft; The first track assembly includes a bearing housing, a gear, a rack, and a first slide rail. The bearing housing is fixedly connected to the motor, the bearing of the bearing housing is connected to the synchronizing rod, the gear is connected to the synchronizing rod, the rack meshes with the gear, the slider of the first slide rail is connected to the bearing housing, and the first slide rail is arranged parallel to the rack. The support assembly includes a connecting rod, a first clamp, and a support platform. The connecting rod is connected to the first clamp, the first clamp is connected to the synchronization rod, and the support platform is connected to the connecting rod. The second track assembly includes a second clamp and a second slide rail. The second clamp is connected to the synchronizing rod, the slider of the second slide rail is connected to the second clamp, and the track of the second slide rail is fixedly set.

[0007] By adopting the above technical solution, the motor in the drive assembly serves as the power source, transmitting torque to the synchronizer rod via a coupling, causing the synchronizer rod to rotate around its axis, thus providing rotational power for the entire system. The synchronizer rod, as the core transmission component, transmits the motor's motion to the gears and support assembly, ensuring the continuity and stability of power transmission. The bearing housing in the first track assembly fixes the motor and supports the synchronizer rod, reducing frictional resistance during rotation. The gears connect to and rotate with the synchronizer rod, converting rotational motion into linear motion through meshing with the rack. The slider of the first slide rail connects to the bearing housing, providing linear guidance for the first track assembly, ensuring the meshing accuracy of the gears and rack, and preventing misalignment. The support assembly... The connecting rod in the component is fixed to the synchronizing rod by the first clamp, transmitting the rotational power of the synchronizing rod to the support platform. The support platform is used to bear the external load, ensuring that the load moves smoothly with the movement of the synchronizing rod. The second clamp in the second track assembly is connected to the synchronizing rod, and the slider of the second slide rail is connected to the second clamp, providing support and guidance for the other end of the synchronizing rod, preventing the synchronizing rod from bending or shaking due to excessive length or excessive load, and improving the overall rigidity and stability of the system. The above-mentioned method eliminates the need to adjust each station individually when adjusting the station spacing, and avoids secondary calibration work after adjustment. It realizes one-time synchronous adjustment and positioning of the spacing between multiple stations, improving the problem of low adjustment efficiency of existing balancing equipment.

[0008] Preferably, there are two bearing seats, which are symmetrically arranged on both sides of the gear, and the two bearing seats are used to support the synchronizing rod.

[0009] By adopting the above technical solution, two bearing seats are symmetrically arranged on the left and right sides of the gear, so that the synchronizing rod has double-point support in the section bearing the motor torque and gear meshing reaction force. The resulting simply supported beam structure reduces the deflection and bending stress of the synchronizing rod caused by excessive span or load eccentricity. The coaxial positioning effect of the two bearing seats keeps the rotation center line of the synchronizing rod parallel to the rack, ensuring that the gear and rack mesh within the stroke and improving the repeatability of linear motion positioning accuracy.

[0010] Preferably, the first clamp is a flat-jaw pliers, and the first clamp is provided with an inclined surface to match the surface of the synchronizing rod.

[0011] By adopting the above technical solution, the first clamp is designed as a flat-jaw vise with an inclined surface. The jaws can fit against the cylindrical surface of the synchronizing rod along the inclined surface. The adjustable opening distance of the flat-jaw vise is compatible with a certain diameter tolerance. During assembly, quick clamping and disassembly can be achieved without additional repairs, thus improving adjustment efficiency.

[0012] Preferably, the center of the support platform is a horizontal metal plate, and the two sides of the support platform extend outward and upward at an angle.

[0013] By adopting the above technical solution, the support platform adopts a configuration with a horizontal metal plate in the middle and two sides extending outward and upward, so that the horizontal metal plate directly bears the main load, while the inclined sections on both sides form self-stabilizing triangular reinforcing ribs when under force, which improves the support of the support platform for the impeller (cylindrical).

[0014] Preferably, the second clamp includes a base, a movable seat, and a cylinder. The base has a first through slot, and semi-circular grooves are symmetrically arranged on the two side walls of the base. The movable seat is movably inserted into the first through slot. The movable seat has a second through slot for accommodating the synchronizing rod. The movable end of the cylinder is fixedly connected to the movable seat, and the fixed end of the cylinder is fixedly connected to the base. The cylinder is used to drive the movable seat to move relative to the base.

[0015] By adopting the above technical solution, the second clamp consists of a base, a movable seat, and a cylinder, forming an openable clamp-like structure. The base provides a lower semi-circular positioning reference for the synchronizing rod through a semi-circular groove. The movable seat slides up and down along the first through groove under the drive of the cylinder. Its second through groove and the base groove can quickly clamp or release the synchronizing rod. The clamping or releasing can be completed by simply controlling the extension and retraction of the cylinder, without the need for manual tightening of bolts, which greatly shortens the adjustment time and improves the adjustment efficiency. In the clamped state, the synchronizing rod is wrapped by the upper and lower semi-circular surfaces. In the released state, it can reduce the vibration transmitted during the operation of other stations and reduce the mutual interference between various stations during the detection and correction process.

[0016] Preferably, the cross-sectional shape of the second through groove is an elongated hole with a variable diameter section, the variable diameter section including a lower clearance area and an upper locking area, the width of the clearance area being greater than the diameter of the synchronizing rod, and the width of the locking area matching the diameter of the synchronizing rod.

[0017] By adopting the above technical solution, the variable diameter elongated hole ensures that when the movable seat descends, the synchronizing rod is located in the avoidance zone, achieving separation from the workstation and isolating mutual interference between workstations; when the movable seat rises, the synchronizing rod enters the locking zone, achieving close cooperation and synchronous movement.

[0018] Preferably, there are multiple first track assemblies and multiple second track assemblies, and these multiple first track assemblies and multiple second track assemblies are spaced apart along the axial direction of the synchronizing rod.

[0019] By adopting the above technical solution, multiple first track components and second track components are arranged at axial intervals on the synchronizing rod, a multi-station synchronous adjustment structure can be constructed. Only one drive component is needed to control the synchronous movement of all stations. The spaced arrangement of the first track components and second track components provides multi-point support, ensuring rigidity and smooth movement throughout the entire stroke.

[0020] Preferably, the motor is a dual-axis motor.

[0021] By adopting the above technical solution, the dual-axis motor is fixed on the first track assembly of one of them, and the output shafts at both ends can be connected to the synchronizing rods respectively. This allows the workstations to be arranged to extend to both sides of the synchronizing rods, realizing the synchronous movement of all driven workstations on both sides by driving from a single point in the middle of the equipment. This avoids the torsional deformation problem caused by excessively long transmission chains in one direction, and is especially suitable for long-size, multi-workstation applications. Furthermore, the configuration method in this embodiment can also eliminate the need for each independent motor and its matching driver, cables, and synchronization program in traditional solutions. This significantly reduces hardware costs and wiring complexity, eliminates mechanical interference caused by signal delays or speed differences between multiple motors, and expands the control length and number of workstations. It also enables long-distance multi-workstation synchronous adjustment with a single motor, reducing hardware costs and wiring complexity, and improving operational reliability.

[0022] In summary, this application includes at least one of the following beneficial technical effects: 1. The motor in the drive assembly serves as the power source, transmitting torque to the synchronizer via a coupling, causing the synchronizer to rotate around its axis, thus providing rotational power for the entire system. The synchronizer, as the core transmission component, transmits the motor's rotational motion to the gears and support assembly, ensuring the continuity and stability of power transmission. The bearing housing in the first track assembly fixes the motor and supports the synchronizer, reducing frictional resistance during rotation. The gear connects to the synchronizer and rotates with it, converting rotational motion into linear motion through meshing with the rack. The slider of the first slide rail connects to the bearing housing, providing linear guidance for the first track assembly, ensuring the meshing accuracy of the gear and rack, and preventing misalignment. The support assembly... The connecting rod is fixed to the synchronizing rod via the first clamp, transmitting the rotational power of the synchronizing rod to the support platform. The support platform bears the external load, ensuring that the load moves smoothly with the movement of the synchronizing rod. The second clamp in the second track assembly is connected to the synchronizing rod, and the slider of the second slide rail is connected to the second clamp, providing support and guidance for the other end of the synchronizing rod. This prevents the synchronizing rod from bending or swaying due to excessive length or heavy load, improving the overall rigidity and stability of the system. Furthermore, adjusting the station spacing eliminates the need to adjust each station individually, avoiding secondary calibration after adjustment. This achieves simultaneous adjustment and positioning of multiple station spacings in one go, improving the low adjustment efficiency of existing balancing equipment. 2. The variable diameter elongated hole ensures that when the movable seat descends, the synchronizing rod is located in the clearance zone, achieving separation from the workstation and isolating mutual interference between workstations; when the movable seat rises, the synchronizing rod enters the locking zone, achieving tight fit and synchronous movement. 3. The dual-axis motor is fixed on the first track assembly of one of them, and the output shafts at both ends can be connected to the synchronizing rods respectively. This allows the workstations to be arranged to extend to both sides of the synchronizing rods, realizing the synchronous movement of all driven workstations on both sides by driving from a single point in the middle of the equipment. This avoids the torsional deformation problem caused by excessively long transmission chains in one direction, and is especially suitable for long-size, multi-workstation applications. Furthermore, the arrangement in this embodiment can also eliminate the need for each independent motor and its matching driver, cables, and synchronization program in traditional solutions. This significantly reduces hardware costs and wiring complexity, and eliminates mechanical interference caused by signal delays or speed differences between multiple motors. While expanding the control length and the number of workstations, it achieves long-distance multi-workstation synchronous adjustment with a single motor, reducing hardware costs and wiring complexity, and improving operational reliability.

[0025] The following is in conjunction with the appendix Figure 1-7 This application will be described in further detail.

[0026] This application discloses a dynamic balancing device for a multi-station cross-flow fan impeller. (Refer to...) Figure 1 The multi-station cross-flow fan impeller dynamic balancing equipment includes a drive assembly 1, a first track assembly 2, a support assembly 3, and a second track assembly 4.

[0027] like Figure 2 and Figure 3 As shown, the drive assembly 1 includes a motor 11 and a synchronizing rod 12. The output shaft of the motor 11 is detachably connected to the synchronizing rod 12 via a coupling. The motor 11 is used to drive the synchronizing rod 12 to rotate around the shaft. The motor 11 in the drive assembly 1 serves as a power source, transmitting torque to the synchronizing rod 12 through the coupling, causing the synchronizing rod 12 to rotate around the shaft. The synchronizing rod 12 serves as the core transmission component, transmitting the motion of the motor 11 to the gear 22 and the support assembly 3, ensuring the continuity and stability of power transmission, thereby providing power for the entire system.

[0028] like Figure 3As shown, the first track assembly 2 includes a bearing housing 21, a gear 22, a rack 23, and a first slide rail 24. The bearing housing 21 is fixedly connected to the motor 11. The bearing of the bearing housing 21 is connected to the synchronizing rod 12. The gear 22 is connected to the synchronizing rod 12. The rack 23 meshes with the gear 22. The slider of the first slide rail 24 is connected to the bearing housing 21. The first slide rail 24 and the rack 23 are arranged parallel to each other. The bearing housing 21 in the first track assembly 2 fixes the motor 11 and supports the synchronizing rod 12, reducing the frictional resistance when the synchronizing rod 12 rotates. The gear 22 is connected to the synchronizing rod 12 and rotates with it. Through meshing with the rack 23, the rotational motion is converted into linear motion. The slider of the first slide rail 24 is connected to the bearing housing 21, providing linear guidance for the first track assembly 2, ensuring the meshing accuracy of the gear 22 and the rack 23, and avoiding deviation.

[0029] In this embodiment, two bearing seats 21 are provided, symmetrically arranged on both sides of the gear 22, and used to support the synchronizing rod 12. The symmetrical arrangement of the two bearing seats 21 on the left and right sides of the gear 22 provides double-point support for the synchronizing rod 12 in the section bearing the torque of the motor 11 and the meshing reaction force of the gear 22. The resulting simply supported beam structure reduces the deflection and bending stress of the synchronizing rod 12 caused by excessive span or load eccentricity. The coaxial positioning effect of the two bearing seats 21 keeps the rotation center line of the synchronizing rod 12 parallel to the rack 23, ensuring that the gear 22 and the rack 23 mesh within the stroke, and improving the repeatability positioning accuracy of linear motion.

[0030] like Figure 4 and Figure 5 As shown, the support assembly 3 includes a connecting rod 31, a first clamp 32, and a support platform 33. The connecting rod 31 is connected to the first clamp 32, the first clamp 32 is connected to the synchronizing rod 12, and the support platform 33 is connected to the connecting rod 31. The connecting rod 31 in the support assembly 3 is fixed to the synchronizing rod 12 through the first clamp 32, which transmits the rotational power of the synchronizing rod 12 to the support platform 33. The support platform 33 is used to bear the external load and ensure that the load moves smoothly with the movement of the synchronizing rod 12.

[0031] In this embodiment, the first clamp 32 is a flat-jaw pliers. The first clamp 32 is provided with an inclined surface to match the surface of the synchronizing rod 12. The first clamp 32 is designed as a flat-jaw pliers with an inclined surface. The jaws can fit against the cylindrical surface of the synchronizing rod 12 along the inclined surface. The adjustable opening distance of the flat-jaw pliers is compatible with a certain diameter tolerance. During assembly, quick clamping and disassembly can be achieved without additional fitting, which improves the adjustment efficiency.

[0032] In this embodiment, several support platforms 33 are provided. The middle part of the support platform 33 is a horizontal metal plate, and the two sides of the support platform 33 extend outward and upward at an angle. The support platform 33 adopts a configuration with a horizontal metal plate in the middle and two sides extending outward and upward at an angle, so that the horizontal metal plate directly bears the main load, while the inclined sections on both sides form self-stabilizing triangular reinforcing ribs when subjected to force, which improves the support of the support platform 33 for the impeller (cylindrical).

[0033] like Figure 6 and Figure 7 As shown, the second track assembly 4 includes a second clamp 41 and a second slide rail 42. The second clamp 41 is connected to the synchronizing rod 12, and the slider of the second slide rail 42 is connected to the second clamp 41. The track of the second slide rail 42 is fixedly set. The second clamp 41 in the second track assembly 4 is connected to the synchronizing rod 12, and the slider of the second slide rail 42 is connected to the second clamp 41, providing support and guidance for the other end of the synchronizing rod 12, preventing the synchronizing rod 12 from bending or shaking due to excessive length or excessive load, and improving the overall rigidity and stability of the system.

[0034] In this embodiment, the second clamp 41 includes a base 411, a movable seat 412, and a cylinder 413. The base 411 has a first through slot, and semi-circular grooves are symmetrically arranged on its two side walls. The movable seat 412 is movably inserted into the first through slot. The movable seat 412 has a second through slot for accommodating the synchronizing rod 12. The movable end of the cylinder 413 is fixedly connected to the movable seat 412, and the fixed end of the cylinder 413 is fixedly connected to the base 411. The cylinder 413 is used to drive the movable seat 412 to move relative to the base 411. The second clamp 41 is composed of the base 411, the movable seat 412, and the cylinder 413. The system forms an openable clamp-like structure. The base 411 provides a lower semi-circular positioning reference for the synchronizing rod 12 through a semi-circular groove. The movable seat 412 slides up and down along the first through groove under the drive of the cylinder 413. Its second through groove can be matched with the groove of the base 411 to quickly clamp or release the synchronizing rod 12. The clamping or releasing can be completed by simply controlling the extension and retraction of the cylinder 413. There is no need to manually tighten the bolts, which greatly shortens the adjustment time and improves the adjustment efficiency. In the clamped state, the synchronizing rod 12 is wrapped by the upper and lower semi-circular surfaces. In the released state, it can reduce the vibration transmitted when other stations are working and reduce the mutual interference between various stations in the detection and correction process.

[0035] Please refer to Figure 7The cross-sectional shape of the second through slot is an elongated hole with a variable diameter section. The variable diameter section includes a lower clearance area and an upper locking area. The width of the clearance area is greater than the diameter of the synchronizing rod 12, and the width of the locking area matches the diameter of the synchronizing rod 12. The variable diameter elongated hole allows the synchronizing rod 12 to be located in the clearance area when the movable seat 412 descends, thus achieving separation from the workstation and isolating mutual interference between workstations. When the movable seat 412 rises, the synchronizing rod 12 enters the locking area, achieving tight fit and synchronous movement.

[0036] For example, in the embodiments of this application, the first slide rail 24 and the second slide rail 42 are both linear guide rails. A plurality of first track components 2 and second track components 4 are provided. The plurality of first track components 2 and the plurality of second track components 4 are spaced apart along the axial direction of the synchronization rod 12. The arrangement of multiple first track components 2 and second track components 4 at axial intervals on the synchronization rod 12 can construct a structure for synchronous adjustment of multiple workstations. Only one drive component 1 is needed to control the synchronous movement of all workstations. The spaced arrangement of the first track components 2 and the second track components 4 provides multi-point support, ensuring rigidity and smooth movement throughout the entire stroke.

[0037] For example, in this embodiment, the motor 11 is a dual-axis motor 11, with the two output shafts of the dual-axis motor 11 rotating in the same direction. The dual-axis motor 11 is fixed on the first track assembly 2 of one of them, and the output shafts at both ends can be connected to the synchronization rod 12 respectively. This allows the workstations to be arranged on both sides of the synchronization rod 12, realizing the synchronous movement of all driven workstations on both sides by driving from a single point in the middle of the equipment. This avoids the torsional deformation problem caused by the excessive length of the transmission chain in one direction, and is especially suitable for long-size, multi-workstation application scenarios. Furthermore, the arrangement in this embodiment can also eliminate the need for each independent motor 11 and its matching driver, cable and synchronization program in the traditional solution, which greatly reduces hardware costs and wiring complexity, and eliminates mechanical interference caused by signal delay or speed difference between multiple motors 11. While expanding the control length and the number of workstations, a single motor 11 can achieve long-distance multi-workstation synchronous adjustment, reducing hardware costs and wiring complexity, and improving operational reliability.

[0038] Specifically, the motor 11 starts as the sole power source, and its output shaft transmits torque to the synchronizing rod 12 via a coupling, driving the synchronizing rod 12 to rotate around its axis. The gear 22 fixed on the synchronizing rod 12 rotates accordingly, converting the rotational motion of the synchronizing rod 12 into linear motion through meshing with the rack 23. This linear motion is transmitted to the slider of the first slide rail 24 via the bearing seat 21, thereby driving the entire first track assembly 2 and its fixed support assembly 3 to produce precise displacement. The support assembly 3 is connected to the synchronizing rod 12 via the first clamp 32, enabling its support platform 33 to carry the workpiece and move synchronously with the system. Simultaneously, the second track assembly 4 is connected to the synchronizing rod 12 via the second clamp 41. The rod 12 is connected, and the second slide rail 42 provides auxiliary support and guidance. The second clamp 41 drives the movable seat 412 through the cylinder 413. Utilizing the variable diameter design of its second through slot, it achieves rigid connection and synchronous movement with the synchronous rod 12 in the locking area, and disengages in the avoidance area to isolate interference. By setting several first and second track components 4 at intervals along the axial direction of the synchronous rod 12 and controlling them with a single drive component 1, the one-time synchronous adjustment and precise positioning of all workstation spacing is finally achieved. When a dual-axis motor 11 is used, it is fixed on the first track component 2 in the middle of the equipment and can output power synchronously to both sides of the synchronous rod 12, further optimizing the transmission chain and improving the system rigidity.

[0039] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
