Description

Technical Field

[0001] This utility model relates to the field of aero-engine maintenance technology, specifically to an auxiliary repair device for compressor rotors. Background Technology

[0002] The compressor rotor of an APU (Auxiliary Power Unit) is a high-speed rotating component that performs work on airflow. The high speed of the compressor rotor allows the compressor to achieve the required performance within a small size and light weight, meeting the operational requirements of the APU. However, under high speed conditions, the rotor components and their connections must withstand enormous inertial forces, gas forces, torque, and complex vibration loads. Prolonged use can easily cause blade damage, and prolonged compression of airflow can also lead to metal buildup on the rotor blades. Even sudden incidents can cause blade damage. Fixing the compressor rotor's worktable during repairs makes it difficult to adjust the repair angle. Utility Model Content

[0003] The purpose of this invention is to provide an auxiliary repair device for compressor rotors, which can adjust the angle for repairing compressor rotors, thereby ensuring the repair accuracy of compressor rotors.

[0004] To solve the above-mentioned technical problems, the present invention adopts the following solution:

[0005] A compressor rotor auxiliary repair device includes a housing and a robotic arm housed within the housing. The robotic arm is equipped with a grinding head for grinding the compressor rotor. The housing contains a mounting platform for mounting the compressor rotor. Below the mounting platform is a turntable for rotating the mounting platform. Below the turntable is a horizontal moving mechanism for moving the turntable within a plane. The robotic arm can utilize any existing technology with rotation and oscillation capabilities, and will not be described in detail. The grinding head also utilizes existing technology, and will not be described in detail. The turntable includes a rotating layer and a fixed layer arranged sequentially from top to bottom. A motor is mounted on the fixed layer, and the output shaft of the motor on the fixed layer is connected to the rotating layer, thereby driving the rotating layer to rotate around the output shaft of the motor on the fixed layer. Its function is to drive the compressor rotor to the machining point of the mechanical arm in the horizontal plane through the turntable and the horizontal moving mechanism. After the compressor rotor reaches the machining point of the mechanical arm, it can rotate the compressor rotor so that all sides of the compressor rotor can be rotated to the machining point of the mechanical arm for machining. Therefore, it is not necessary to frequently adjust the machining point of the mechanical arm and the position of the compressor rotor during the repair process, thus ensuring the repair accuracy.

[0006] Furthermore, the mounting platform is provided with a fixing rod for the compressor rotor to pass through, and the fixing rod is threaded with a clamping bolt for pressing the compressor rotor onto the mounting platform.

[0007] Furthermore, the mounting platform is equipped with four clamping tracks evenly distributed in a ring around the fixed rod. Each clamping track contains a drive screw with its axis perpendicular to the fixed rod and a clamping block threadedly connected to the drive screw. Its function is to fix and clamp the compressor rotor by means of the clamping blocks and clamping tracks.

[0008] Furthermore, the clamping block has a clamping surface at one end facing the fixing rod for clamping the outer edge of the compressor rotor, and the clamping surface has anti-slip textures evenly distributed from top to bottom. Its function is to facilitate the clamping of the outer edge of the compressor rotor with a smaller outer diameter by moving each clamping block toward the fixing rod, thereby achieving the effect of fixing the compressor rotor.

[0009] Furthermore, the end of the clamping block facing away from the fixing rod is stepped, with its length gradually decreasing from top to bottom. Its function is to facilitate the movement of each clamping block away from the fixing rod to support the inner wall of the compressor rotor outwards, thereby achieving the effect of fixing the compressor rotor.

[0010] Furthermore, the horizontal moving mechanism includes a longitudinal moving mechanism and a lateral moving mechanism, with the longitudinal moving mechanism and the lateral moving mechanism arranged perpendicularly. Its function is to allow the compressor rotor on the mounting platform to be moved to any position on the horizontal plane through the combined arrangement of the longitudinal and lateral moving mechanisms.

[0011] Furthermore, the longitudinal moving mechanism is provided with a longitudinal slide rail, a longitudinal slider is provided on the longitudinal slide rail, a transverse moving mechanism is provided on the longitudinal slider, a transverse slide rail is provided on the transverse slide rail, a transverse slider is provided on the transverse slider, and a support platform for mounting the turntable is provided on the transverse slider. The longitudinal track and the transverse track are arranged perpendicularly.

[0012] Furthermore, a movable slide is provided below the robotic arm for moving the robotic arm. A movable slide rail is provided on the movable slide rail, and a movable sliding plate for mounting the robotic arm is provided on the movable slide rail. The extension direction of the movable sliding plate is parallel to the extension direction of the longitudinal slide rail. Its function is that, by setting up the movable slide, the position of the robotic arm can be adjusted according to the outer contour dimensions of the compressor rotor before repair processing, facilitating precise alignment for repair processing.

[0013] Furthermore, the movable slide, longitudinal moving mechanism, and lateral moving mechanism are driven by motor-screw mechanisms. The installation of the motor-screw mechanisms on the movable slide, longitudinal moving mechanism, and lateral moving mechanism utilizes existing technology and will not be described in detail.

[0014] Furthermore, the housing is equipped with a 3D scanner for scanning the compressor rotor. Its function is to scan for damage on the compressor rotor and perform precise repairs.

[0015] The beneficial effects of this utility model are:

[0016] 1. By setting up a turntable and a horizontal moving mechanism, the compressor rotor can be moved horizontally to the machining point of the mechanical arm of the motor. After the compressor rotor reaches the machining point of the mechanical arm, it can rotate the compressor rotor so that all sides of the compressor rotor can be rotated to the machining point of the mechanical arm for machining. Therefore, during the repair process, it is not necessary to frequently adjust the machining point of the mechanical arm and the position of the compressor rotor, thus ensuring the repair accuracy.

Below the mounting platform 4 is a turntable 5 for rotating the mounting platform 4. Below the turntable 5 is a horizontal moving mechanism for moving the turntable 5 within a plane. The robotic arm 2 can utilize any existing technology with rotation and oscillation capabilities, and will not be described in detail. The grinding head 3 also utilizes existing technology and will not be described in detail. The turntable 5 includes a rotating layer and a fixed layer arranged sequentially from top to bottom. A motor is mounted on the fixed layer, and the output shaft of the motor on the fixed layer is connected to the rotating layer, thereby causing the rotating layer to rotate around the output shaft of the motor on the fixed layer. Its function is that, through the setting of the turntable 5 and the horizontal moving mechanism, it can not only drive the compressor rotor to move in the horizontal plane to the processing point of the mechanical arm 2 of the motor, but also rotate the compressor rotor after it reaches the processing point of the mechanical arm 2, so that all sides of the compressor rotor can be rotated to the processing point of the mechanical arm 2 for processing. Thus, during the repair process, it is not necessary to frequently adjust the processing point of the mechanical arm 2 and the position of the compressor rotor, ensuring the repair accuracy.

[0026] Specifically, such as Figure 2 As shown, the mounting platform 4 is provided with a fixing rod 6 for the compressor rotor to pass through, and a clamping bolt 7 for pressing the compressor rotor onto the mounting platform 4 is threadedly connected to the fixing rod 6.

[0027] Specifically, such as Figure 2 As shown, the mounting platform 4 is provided with four clamping tracks 8 evenly distributed in a ring around the fixing rod 6. Each clamping track 8 is provided with a drive screw whose axis is perpendicular to the fixing rod 6 and a clamping block 10 threadedly connected to the drive screw. Its function is to fix and clamp the compressor rotor through the arrangement of the clamping block 10 and the clamping track 8.

[0028] Specifically, such as Figure 2As shown, the clamping block 10 has a clamping surface at one end facing the fixing rod 6 for clamping the outer edge of the compressor rotor. The clamping surface has anti-slip textures evenly distributed from top to bottom. Its function is to facilitate the clamping of the outer edge of the compressor rotor with a smaller outer diameter by moving each clamping block 10 toward the fixing rod 6, thereby achieving the effect of fixing the compressor rotor.

[0029] Specifically, such as Figure 2 As shown, the clamping block 10 has a stepped shape with its length gradually decreasing from top to bottom at the end facing away from the fixing rod 6. Its function is to facilitate the movement of each clamping block 10 away from the fixing rod 6 to support the inner wall of the compressor rotor outward, thereby achieving the effect of fixing the compressor rotor.

[0030] Specifically, such as Figure 3 As shown, the horizontal moving mechanism includes a longitudinal moving mechanism and a lateral moving mechanism, with the longitudinal moving mechanism and the lateral moving mechanism arranged perpendicularly. Its function is to allow the compressor rotor on the mounting platform 4 to be moved to any position on the horizontal plane through the combined arrangement of the longitudinal and lateral moving mechanisms.

[0031] Specifically, such as Figure 3 As shown, the longitudinal moving mechanism is equipped with a longitudinal slide rail, a longitudinal slider is mounted on the longitudinal slide rail, a transverse moving mechanism is mounted on the longitudinal slider, a transverse slide rail is mounted on the transverse slide rail, a transverse slider is mounted on the transverse slider, and a support platform for mounting the turntable 5 is mounted on the transverse slider. The longitudinal track and the transverse track are arranged perpendicularly.

[0032] Specifically, such as Figure 1 As shown, a movable slide is provided below the robotic arm 2 for moving the robotic arm 2. A movable slide rail is provided on the movable slide rail, and a movable sliding plate for mounting the robotic arm 2 is provided on the movable slide rail. The extension direction of the movable sliding plate is parallel to the extension direction of the longitudinal slide rail. Its function is that, by setting up the movable slide, the position of the robotic arm 2 can be adjusted according to the outer contour dimensions of the compressor rotor before repair processing, facilitating precise alignment for repair processing.

[0033] Specifically, such as Figure 1 As shown, the movable slide, longitudinal moving mechanism, and lateral moving mechanism are driven by motor-screw mechanisms. The installation of the motor-screw mechanisms on the movable slide, longitudinal moving mechanism, and lateral moving mechanism adopts existing technology and will not be described in detail.

[0034] Specifically, the housing 1 is equipped with a 3D scanner for scanning the compressor rotor. Its function is to scan for damage on the compressor rotor and perform precise repairs.

[0035] The working principle of this embodiment is explained as follows: First, the compressor rotor is mounted on the fixed rod 6. The clamping bolt 7 is twisted to clamp the compressor rotor, and the drive bolt 9 is rotated to fix the compressor rotor. Then, the longitudinal and lateral moving mechanisms are driven to move the compressor rotor to the processing point of the robotic arm 2. Once the robotic arm 2 is moved to the processing point, the grinding head 3 can be started to grind and repair the compressor rotor. After the compressor rotor on the current side is repaired, the turntable 5 is rotated to rotate the other sides of the compressor rotor that need to be repaired to the processing point of the robotic arm 2, and processing can continue.

[0036] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any way. Any simple modifications, equivalent substitutions, and improvements made to the above embodiments based on the technical essence of the present utility model and within the spirit and principles of the present utility model shall still fall within the protection scope of the present utility model.
