[0053] Specifically, the first adjustment drive member can be a hydraulic cylinder, a linear motor, a motor-driven screw structure, or other devices capable of linear motion. A hydraulic cylinder is preferably used, the cylinder body of the hydraulic cylinder being fixedly connected to the surface of the pitch platform, and the end of the telescopic rod 602 of the hydraulic cylinder being fixedly connected to the first support member 101; Figure 1As shown, the bottom of the first support member 101 is provided with an inverted trapezoidal groove for sliding connection with the first trapezoidal slide rail on the side rolling base. The side rolling base is a flat plate. The side rolling base is used to be fixedly connected to the pitch platform in the engine pitch test device. By adopting the inverted trapezoidal groove and the inverted trapezoidal slide rail for sliding connection, the movement accuracy of the first support member 101 is improved. Figure 1 and Figure 2 As shown, the first support member 101 is provided with a circular groove, and a circular through-hole is provided at the bottom of the circular groove. The outer ring of the slewing support is inserted into the circular groove and fixedly connected to the bottom of the circular groove. The fixing method can be bolting, welding, or other fixing methods. The inner ring of the slewing support is rotatably connected to the outer ring. The inner ring of the slewing support is the first rolling member 102. The circular through-hole provides installation space for test equipment and aircraft engines. In an alternative embodiment, the first rolling member 102 can also be the inner ring of a bearing or a semi-arc roller table. The mounting seat 300 is elongated, and the bottom of the mounting seat 300 is slidably connected to the inner bottom wall of the first rolling member 102 via a trapezoidal slide rail 4022 and an inverted trapezoidal slide groove.

The engine bracket is then fixedly connected to the corresponding mounting portion, and the aircraft engine is then fixedly connected to the engine bracket to complete the assembly of the aircraft engine. For different types of aircraft engines, the distance between the first rolling member 102 and the roll drive member 201 is adjusted by the first adjusting drive member to meet the size requirement for installing the aircraft engine. In addition, different mounting portions are connected to corresponding engine mounting brackets to adapt to different types of aircraft engines. The engine roll test device provided in the present application can meet the roll test of different aircraft engines, thereby improving the versatility of the engine roll test device.

[0055] like Figure 1As shown, in the engine roll test device provided by this embodiment, any mounting portion includes two mounting surfaces 301, and the number of mounting surfaces 301 can be adjusted as needed. The two mounting surfaces 301 are flush to ensure that the heights of both sides of the aircraft engine are consistent after installation, thereby reducing the vibration generated by the aircraft engine during operation. The two mounting surfaces 301 are spaced apart along the width direction of the mounting seat 300, and a plurality of mounting holes 3011 are opened on any mounting surface 301. The plurality of mounting holes 3011 are evenly spaced along a first direction. The plurality of mounting holes 3011 can also be distributed proportionally or unequally. The first direction is the length direction of the mounting seat 300, which constitutes a row of mounting holes 3011 on the mounting surface 301. The mounting surface 301 can also be provided with multiple rows of mounting holes 3011. In this embodiment, two rows of mounting holes 3011 are provided, and the aircraft engine is fixedly connected to the engine mounting frame by high-strength bolts. The aircraft engine can be conveniently fixed through the mounting portion.

[0056] like Figure 2 As shown, the engine roll test device provided in this embodiment is provided with two mounting parts, the number of which can be adjusted as needed, and the two mounting parts are spaced apart along a second direction, which is a direction perpendicular to the upper surface of the mounting seat 300, that is, there is a height difference between the two mounting parts, and there is a spacing value between the two mounting surfaces 301 of any mounting part, and each spacing value decreases successively. Through this design, the number of different mounting parts on the mounting seat 300 is increased, thereby increasing the types of aircraft engines that can be installed on the mounting seat 300, and further improving the versatility of the engine roll test device.

[0057] like Figures 1 to 3 As shown, the engine roll test device provided in this embodiment also includes a second support member 401, a second rolling member 402 and a second adjustment drive member. The bottom of the second support member 401 is provided with an inverted trapezoidal groove for sliding connection with the second trapezoidal slide rail on the side roll base. The side roll base is used to be fixedly connected to the pitch platform in the engine pitch test device. By adopting the inverted trapezoidal groove and the inverted trapezoidal slide rail for sliding connection, the movement accuracy of the second support member 401 is improved. Figure 1 As shown, a circular groove is provided on the second support member 401, and a circular through hole is provided at the bottom of the circular groove. The inner ring of the slewing support is inserted into the center groove and fixedly connected to the bottom of the circular groove. The outer ring of the slewing support extends out of the circular groove. The outer edge of the slewing support is rotatably connected to the inner ring. The outer ring of the slewing support is the second rolling member 402. The circular through hole provides installation space for test equipment and aircraft engines. Figure 1Taking the perspective of as an example, the exhaust pipe 700 is fixedly connected to the outer ring of the slewing support through the fixed arm 4021. The exhaust pipe 700 is used to discharge the exhaust gas from the tail of the aircraft engine. The fixed arm 4021 includes a support arm and a mounting plate. The support arm is fixedly connected to the outer ring of the slewing support by bolts, and the support arm extends toward the center of the slewing support. The end of the support arm is hinged to the mounting plate, and the mounting plate is fixedly connected to the outer wall of the exhaust pipe 700 by bolts. In an alternative embodiment, the first rolling member 102 can also be a bearing inner ring or a semi-arc roller table, and the bottom of the mounting seat 300 is connected to the second rolling member 4 by a trapezoidal slide rail and an inverted trapezoidal slide groove. 02 is slidably connected to the inner bottom wall, the first rolling member 102 and the second rolling member 402 are spaced apart, the second adjustment drive member can be a hydraulic cylinder, a linear motor, a motor-driven screw structure, or other equipment that can perform linear motion. The second adjustment drive member is installed on the first rolling member 102 and connected to the mounting seat 300. The second adjustment drive member can drive the mounting seat 300 to move in the direction of movement of the first rolling member 102, thereby facilitating the position adjustment between the aircraft engine and other test equipment, thereby improving the assembly efficiency of the engine roll test device, the aircraft engine and other test equipment.

[0058] In an alternative embodiment, the shapes of the first support member 101 and the second support member 401 are adapted to the shapes of the first rolling member 102 and the second rolling member 402 , for example, the first support member 101 and the second support member 401 are both semi-arc-shaped plates.

[0059] like Figure 1 and Figure 2 As shown, the engine roll test device provided in this embodiment has a second adjustment drive member including a screw, a nut, and a handwheel 501. Support frames are provided at both ends of the screw, and the support frames are fixedly connected to the bottom of the mounting seat 300. Both ends of the screw are rotatably connected to the corresponding support frames. The handwheel 501 is fixedly connected to one end of the screw, and the nut is fixedly connected to the inner wall of the first rolling member 102. The nut is sleeved on the outer periphery of the screw and connected to the screw nut. By rotating the handwheel 501, the handwheel 501 drives the screw to rotate. Since the nut is fixed to the first rolling member 102 and the screw is threadedly connected to the nut, the screw is gradually screwed into the nut and drives the mounting seat 300 to move. The handwheel 501 can drive the mounting seat 300 to move through the cooperation of the screw and the nut, thereby accurately adjusting the position of the mounting seat 300.

[0060] The engine roll test device provided in this embodiment also includes a third adjustment drive component, which is a hydraulic cylinder, a linear motor, a motor-driven screw structure, or other equipment that can perform linear motion. A hydraulic cylinder is preferably used, and the cylinder body of the hydraulic cylinder is fixedly connected to the surface of the pitch platform. The end of the telescopic rod 602 of the hydraulic cylinder is fixedly connected to the second support member 401. The third adjustment drive component can drive the second rolling member 402 away from or close to the first rolling member 102. The third adjustment drive component can also change the distance between the second rolling member 402 and the first rolling member 102, thereby increasing the flexibility of adjusting the distance between the second rolling member 402 and the first rolling member 102.

[0061] The engine roll test device provided in this embodiment comprises a first rolling member 102 which is an inner ring of a rotary support, a second rolling member 402 which is an outer ring of a rotary support, and a first gear which is provided on the outer periphery of the second rolling member 402. The roll driving member comprises a motor, a reducer 202 and a coupling 203. The housings of the motor, the reducer 202 and the coupling 203 are all fixedly connected to the second support member 401. The output shaft of the motor is fixedly connected to the input shaft of the reducer 202. The output shaft of the reducer 202 is fixedly connected to the input shaft of the coupling 203. A second gear is sleeved on the output shaft of the reducer 202, and the second gear is meshed with the first gear. The number of teeth of the second gear is smaller than that of the first gear, so as to increase the driving force of the second gear. The torque of rolling element 402 is used by the motor to rotate reducer 202, which in turn drives coupling 203. Coupling 203, via the second gear and the first gear, drives second rolling element 402. Second rolling element 402 drives mounting base 300, which in turn drives the first rolling element. This allows the engine on mounting base 300 to roll. The first rolling element 102 can rotate 360° around the first support member, and the second rolling element 402 can also rotate 360° around the second support member. Driven by the motor, this allows the mounting base to rotate 360°, allowing the aircraft engine to roll from -180° to +180°, thus achieving full-angle roll. The motor can also drive mounting base 300 back to its initial position, a return-to-zero function that improves the safety of the engine roll test apparatus. A protective cover is installed above the motor, the reducer 202 and the coupling 203 to protect the motor, the reducer 202 and the coupling 203 from being contaminated by oil leaked during the engine test.

[0062] The engine roll test apparatus provided in this embodiment also includes a brake disc, a brake actuator, and a brake caliper. The brake disc is mounted on the outer periphery of the second rolling member 402. The brake actuator is a hydraulic cylinder or a motor. The forklift caliper is connected to the brake actuator. When the second rolling member 402 needs to stop rotating, the brake actuator drives the brake caliper to clamp the brake disc, increasing the friction between the caliper and the brake disc, thereby decelerating the second rolling member 402. When the second rolling member 402 needs to operate normally, the brake actuator drives the brake caliper to release the brake disc, allowing the second rolling member 402 to rotate normally. When the aircraft engine reaches the support roll angle, the brake actuator activates to stop the second rolling member 402 and maintain its position, thereby locking the aircraft engine's roll angle.

[0063] The engine roll test device provided in this embodiment also includes four telescopic parts, and any telescopic part includes a cylinder 601 and a telescopic rod 602. The cylinder 601 is sleeved on the outer circumference of a portion of the telescopic rod 602, and the telescopic rod 602 is slidably connected to the inner wall of the cylinder 601. The end of the cylinder 601 away from the telescopic rod 602 is hinged to the second rolling part 402, and the end of the telescopic rod 602 away from the cylinder 601 is connected to the first rolling part 102. The four telescopic parts are distributed between the first rolling part 102 and the second rolling part 402 at intervals around the axis of the first rolling part 102. The telescopic parts can adjust their own length to adapt to the distance between the first rolling part 102 and the second rolling part 402. The telescopic parts can improve the connection strength between the first rolling part 102 and the second rolling part 402, thereby improving the stability of the first rolling part 102 and the second rolling part 402, and then improving the stability of the entire engine roll test device.

[0064] In the engine roll test device provided in this embodiment, a plurality of wiring holes are provided on the first support member 101 and the second support member 401 for fixing the test cables of the aircraft engine.

[0065] Example 2

[0066] The engine full-attitude test device provided in this embodiment includes an engine pitch test device and the engine roll test device of Example 1. The engine pitch test device includes two servo electric cylinders, a pitch platform, and a base. The two servo electric cylinders are fixedly connected to the base and spaced apart. The extended ends of the two servo electric cylinders are respectively hinged to the two sides of the bottom of the pitch platform. The pitch angle of the pitch platform is controlled by the height difference between the extended ends of the two servo electric cylinders. The roll base is fixedly connected to the upper surface of the pitch platform. The pitch of the aircraft engine is achieved by the engine pitch test device, and the roll of the aircraft engine is achieved by the engine roll test device, thereby realizing full-attitude testing of the aircraft engine.
