Description

Technical Field

[0001] This utility model relates to the field of aero-engine test bench technology, specifically to an attitude adjustment test bench. Background Technology

[0002] Aero-engine bench technology is a core component of aero-engine research, development, testing, and certification, involving complex engineering systems and multidisciplinary technologies.

[0003] Most test benches currently on the market are non-standard and custom-made, lacking versatility. In specific tests, test benches undergo extensive non-standard structural and functional designs to meet experimental requirements. The following are common test bench types: Servo electric cylinder technology: While conventional electric cylinders can drive the lifting and lowering of heavy-load workpieces, servo electric cylinders can precisely control the lifting and lowering displacement of the electric cylinder; Heavy-load linear guide technology: By constraining a certain degree of freedom through guide rails, the workpiece can achieve unidirectional reciprocating motion; Fixed test bench: Utilizing a frame structure connected to fixed mounting sections and workpieces of fixed dimensions, it serves to fix the workpiece. The workpiece fixing fixture is connected via guide rails, enabling simple translation adjustment. Combined with electric cylinder-driven lifting of the entire workpiece, it achieves upward and downward adjustment.

[0004] The existing aero-engine attitude adjustment test bench suffers from the following drawbacks: During workpiece attitude adjustment, the offset readings cannot be quantified and controlled during angular deflection and pitch, and significant displacement of the center point occurs during angular deflection, leading to difficulties in alignment when connecting flanges. The test bench occupies a large space, making operation around the workpiece inconvenient during related tests, and in severe cases, it may interfere with the workpiece's piping and other components. It also has limited adaptability to workpieces of different sizes. Therefore, to address these issues, we have proposed an attitude adjustment test bench. Utility Model Content

Sliding sleeves 5 are fitted around the outside of the guide rails 3. A movable plate 4 is connected to the top of the sliding sleeves 5. A toothed plate 6 and a support base 8 are connected to one end of the top of the base plates 1. A rotating handle 7 is located on one side of the support base 8. The rotating end of the rotating handle 7 passes through the support base 8 and is fixedly fitted with a gear that meshes with the toothed plate 6. Guide rails 9 are connected to both ends of the top of the movable plate 4. Sliding sleeves 10 are fitted on both sides of the top of the guide rails 9. Each of the tops of the 10 is connected to a support assembly 2. Both sides of the top of the movable plate 4 are connected to support seats 2 13. One side of one of the support seats 2 13 is provided with a rotating handle 2 12. The rotating end of the rotating handle 2 12 passes through the support seat 2 13 and is connected to a drive screw 15. One side of the drive screw 15 is movably fitted with a support seat 3 16 through a bearing. The external thread of the drive screw 15 is fitted with a movable sleeve 11. One side of the movable sleeve 11 is connected to a drive plate 14. The support assembly 2 includes a base 21. The other side of the top of the movable plate 4 is also provided with a drive plate 14.

[0023] As a technical optimization of this utility model, the top of one side of the support base 8 is connected to the movable plate 4, and the bottom of the support base 3 16 is connected to the top of the movable plate 4; the drive screw 15 can be supported by the support base 3 16.

[0024] As a technical optimization of this utility model, a rotating notch is provided through the drive plate 14 to cooperate with the drive screw 15, and the bottom of the drive plate 14 slides in contact with the top of the moving plate 4; the rotating notch facilitates the left and right movement of the drive plate 14.

[0025] As a technical optimization of this utility model, each of the two bases 21 has a column 26 connected to the side of the top of the bases 21 that is far apart from each other, and each of the two columns 26 has a guide rail 29 connected to the side of the opposite base. The guide rail 29 is fitted with a sliding sleeve 28, and each of the two drive plates 14 is connected to the column 26 on the side of the opposite base.

[0026] As a technical optimization of this utility model, an electric cylinder 22 is connected to the top of the base 21, and a protective cover 27 is connected to the top of the base 21 and outside the electric cylinder 22. The telescopic end of the electric cylinder 22 passes through the protective cover 27 and is movably connected to a fixed seat 25 through a rotating shaft. One side of the fixed seat 25 is connected to a sliding sleeve 28.

[0027] As a technical optimization of this utility model, a tapered bearing 23 is installed through the interior of the fixed seat 25, and a pin-type connecting seat 24 is connected to one side of the tapered bearing 23. The fixed seat 25, the tapered bearing 23 and the pin-type connecting seat 24 are combined to form an installation section structure. The tapered bearing 23 serves as a joint structure to ensure a certain degree of freedom under load. The electric cylinder 22 provides driving force in the Z-axis direction. The installation section is connected to the workpiece in a two-joint manner to ensure that the workpiece has a degree of freedom to release its pitch and deflection stroke.

[0028] In use, the entire platform is fixed at the base plate 1, with guide rail 2 9, sliding sleeve 2 10, and base 21 forming the X-axis platform for movement in the X-axis direction. The moving plate 4, guide rail 1 3, and sliding sleeve 1 5 form the Y-axis platform for movement in the Y-axis direction. Because there are two base plates 1, the entire platform is divided into two parts, allowing for relative movement and expanding the workpiece's adaptability. The electric cylinder 22 provides driving force in the Z-axis direction. The mounting section is connected to the workpiece using a two-joint design, ensuring freedom of movement for workpiece pitch and deflection. For left-right movement in the X-axis direction, rotating handle 2 12 clockwise or counterclockwise drives the drive screw 15 clockwise or counterclockwise, causing the moving sleeve 11 to move left or right. The right-side drive plate 14 then drives the right-side support assembly 2 to move left or right. For forward-backward movement in the Y-axis direction, rotating handle 1 7 clockwise or counterclockwise, with the cooperation of gears and gear plates 6, moves the moving plate 4 forward or backward.

[0029] The test bench is operated interactively via PLC and uses a host computer. Before adjusting the posture, the test parameters are input into the host computer through the PLC-controlled electric cylinders 22. The PLC algorithm calculates the required lifting distance for the four support components 4 corresponding to the adjusted posture. When the workpiece is hoisted to the target position, the four electric cylinders 22 extend to the corresponding length, moving the four pin-type connecting seats 24 to their corresponding positions. The workpiece is supported by the four pin-type connecting seats 24, and finally, the workpiece is connected to the pin-type connecting seats 24 using pins.
