DETAILED DESCRIPTION

[0030] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0031] Refer to the instruction manual Figure 1-Figure 10 An adjustable angle assembly platform for assembling an aircraft engine comprises a base 1, an adjustment seat 2 is arranged above the base 1, a support platform 3 is arranged above the adjustment seat 2, and shock absorbing devices 4 are rotatably connected on both sides between the adjustment seat 2 and the support platform 3.

[0032] like Figure 1-Figure 2 and Fig.10As shown, the shock absorbing device 4 includes two shock absorbing plates 41 , which are arranged opposite to each other one above and one below, and a steel wire rope 42 is spirally passed through the two shock absorbing plates 41 .

[0033] It should be noted that the upper damping plate 41 is rotatably connected to the support platform 3, and the lower damping plate 41 is rotatably connected to the adjustment seat 2, and through the spiral wire rope 42, it can play a damping role in all directions.

[0034] In this embodiment, an angle adjustment device 5 is provided on the inner side of the base 1, and the angle adjustment device 5 includes two parallel worm gears 51, both ends of the two worm gears 51 are rotatably connected to the base 1, and two rotating drive components 52 are installed at one end of the base 1, and the two rotating drive components 52 are respectively used to drive the two worm gears 51 to rotate; the angle adjustment device 5 also includes a moving frame 53, and the moving frame 53 is rotatably connected to a main shaft 54, and the main shaft 54 ​​is fixedly connected to a worm gear 55, and the worm gear 55 is arranged between the two worm gears 51 and meshes with the two worm gears 51.

[0035] Furthermore, if Figure 3 and Figure 6 As shown, a guide rod 511 is disposed on one side of each of the two worm gears 51 . The guide rod 511 is fixedly connected to the base 1 , and both ends of the movable frame 53 are slidably disposed on the two guide rods 511 .

[0036] It should be noted that the rotation drive component 52 is a servo motor, and the two rotation drive components 52 drive the two worms 51 to rotate separately. When the two worms 51 rotate in the same direction and at the same speed, the worm wheel 55, the moving frame 53 and the main shaft 54 ​​can be driven to move linearly along the axis direction of the worm 51. By controlling the rotation direction of the two worms 51, the moving direction of the worm wheel 55, the moving frame 53 and the main shaft 54 ​​can be controlled. When the two worms 51 rotate in opposite directions and at the same speed, the worm wheel 55 will stop moving and rotate. By controlling the rotation direction of the two worms 51, the rotation direction of the worm wheel 55 can be controlled.

[0037] In this embodiment, an angle adjustment component 56 is provided at one end of the movable frame 53, and the angle adjustment component 56 includes an adjustment arm 563 and a push plate 564. The push plate 564 is fixedly connected to one end of the movable frame 53, and one end of the adjustment arm 563 is hinged to the end of the adjustment seat 2; both sides of the movable frame 53 are provided with a posture adjustment mechanism, and the posture adjustment mechanism includes a clutch component 57, and the clutch component 57 includes a fixed frame 571, and a turntable 572 is rotatably connected to the fixed frame 571. The turntable 572 is used to separate or combine with the main shaft 54, and the posture adjustment mechanism also includes a rotating component 58; when the two worm gears 51 rotate in opposite directions, the turntable 572 is combined with the main shaft 54, and the turntable 572 drives the shock absorbing device 4 to rotate through the rotating component 58. When the two worm gears 51 rotate in the same direction, the turntable 572 is separated from the main shaft 54, and the push plate 564 pushes the adjustment arm 563 to lift the adjustment seat 2.

[0038] In the above technical solution, if Figure 3 and Figure 6 As shown, the angle adjustment assembly 56 includes a slide rail 561, one end of which is fixedly connected to the base 1, a slider 562 is slidably arranged inside the slide rail 561, an end of an adjustment arm 563 away from the adjustment seat 2 is hinged to the slider 562, and one end of a push plate 564 is aligned with the slider 562 and is used to push the slider 562 to slide inside the slide rail 561.

[0039] Furthermore, if Figure 3 As shown, one end of the adjustment seat 2 is fixedly connected to a long shaft 21 , and the adjustment seat 2 is rotatably connected to the base 1 through the long shaft 21 .

[0040] It should be noted that when the worm gear 55, the movable frame 53 and the main shaft 54 ​​move together, the push plate 564 can contact the slider 562 and push the slider 562 forward, the slider 562 slides inside the slide rail 561, and drives the end of the adjusting arm 563 to move, so that the adjusting arm 563 pushes the end of the adjusting seat 2 upward, and the adjusting seat 2 rotates upward around the long axis 21, thereby achieving the purpose of adjusting the angle of the adjusting seat 2.

[0041] In the above technical solution, if Figure 4-Figure 8 As shown, the turntable 572 is located directly above the main shaft 54 ​​, a coupling groove 573 is provided in the middle of the lower surface of the turntable 572 , and a coupling block 541 is fixedly connected to the upper end of the main shaft 54 ​​, and the coupling block 541 is used to be inserted into the coupling groove 573 .

[0042] Furthermore, the rotating assembly 58 includes a rotating shaft 580, which is rotatably connected to the adjustment seat 2 and fixedly installed at the bottom of the shock absorbing device 4. A small gear 581 is fixedly connected to the bottom of the rotating shaft 580, and a large gear 582 is rotatably connected to the bottom of the adjustment seat 2. The large gear 582 is meshed with the small gear 581. One side of the large gear 582 is fixedly connected to shaft one 583, and one side of the turntable 572 is fixedly connected to shaft two 584. The rotating assembly 58 also includes a connecting rod 1 585, and both ends of the connecting rod 1 585 are respectively hinged to shaft one 583 and shaft two 584.

[0043] Furthermore, the fixing frame 571 is fixedly connected to the two guide rods 511 .

[0044] It should be noted that when the worm gear 55 and the main shaft 54 ​​rotate, the main shaft 54 ​​can drive the turntable 572 to rotate, the turntable 572 pulls the large gear 582 to rotate through the connecting rod 585, and the large gear 582 drives the shock absorber 4 to rotate through the small gear 581 and the rotating shaft 580.

[0045] In this embodiment, the implementation method is as follows: when the platform is in use, a clamp is installed on the support platform 3, and the aircraft engine is clamped by the clamp. Then, the staff can assemble the aircraft engine on the platform. According to the requirements of the posture when assembling the aircraft engine, its angle needs to be adjusted. When adjusting, the adjustment seat 2 and the support platform 3 are tilted, that is, the adjustment seat 2 is rotated upward around the long axis 21 by a certain angle. Specifically, when the angle is not adjusted, that is, when the adjustment seat 2 is kept horizontal, as shown in FIG. Figure 1-Figure 3 As shown, the length direction of the shock absorbing device 4 is parallel to the length direction of the adjusting seat 2, that is, the axial direction of the steel wire rope 42 is parallel to the length direction of the adjusting seat 2 (the axial direction of the steel wire rope 42 is as shown in FIG. Fig.10 The engaging block 541 is also inserted into the engaging groove 573.

[0046] When adjusting the angle: First, the two worms 51 are driven to rotate by two rotating drive components 52, and the rotation directions are opposite and the rotation speeds are equal. At this time, the worm wheel 55 and the main shaft 54 ​​rotate at the same time, and the main shaft 54 ​​drives the turntable 572 to rotate through the engagement block 541 inserted into the engagement groove 573. The turntable 572 pulls the large gear 582 to rotate an angle through the shaft 2 584, the connecting rod 1 585 and the shaft 1 583, so that the large gear 582 drives the shock absorber 4 to rotate about 90° through the small gear 581 and the rotating shaft 580, so that the axial direction of the wire rope 42 can be rotated from parallel to the length direction of the adjustment seat 2 to basically vertical. When the shock absorber 4 rotates, the direction of the engagement groove 573 is exactly parallel to the axial direction of the worm 51. In this way, when the two rotating drive components 52 drive the two worms 51 to rotate in the same direction and at the same speed to drive the moving frame 53, the main shaft 54 ​​and the worm wheel 55 to move, the engagement block 541 can be moved out of the engagement groove 573.

[0047] Then, the two rotating drive components 52 drive the two worms 51 to rotate in the same direction at the same speed, driving the moving frame 53, the main shaft 54 ​​and the worm gear 55 to move, the moving frame 53 drives the push plate 564 to move, the push plate 564 pushes the slider 562, so that the slider 562 moves inside the slide rail 561, and the slider 562 drives the adjustment arm 563 to lift the end of the adjustment seat 2, so that the adjustment seat 2 rotates upward around the long axis 21, thereby achieving the purpose of adjusting the angle of the adjustment seat 2, and the support platform 3 rotates with the adjustment seat 2. By controlling the distance that the push plate 564 pushes the slider 562, the purpose of adjusting different angles can be achieved.

[0048] When the adjustment seat 2 needs to be adjusted from a tilted state to a horizontal state: First, the two rotating drive components 52 drive the two worm gears 51 to rotate in the same direction at the same speed, driving the movable frame 53, the main shaft 54 ​​and the worm gear 55 to move in the direction away from the slider 562, and the push plate 564 gradually separates from the slider 562. Under the pressure of the adjustment seat 2 and the support platform 3, the slider 562 slides in the direction of the movable frame 53, so that the adjustment seat 2 and the support platform 3 can be rotated downward to a horizontal state.

[0049] Then, the moving frame 53, the main shaft 54 ​​and the worm gear 55 move toward the direction of the clutch assembly 57. When the engagement block 541 is inserted into the engagement groove 573, the two worms 51 are driven to rotate by the rotating driving component 52, and the rotation directions are opposite and the rotation speeds are equal. In this way, the worm gear 55 and the main shaft 54 ​​can be driven to rotate. The turntable 572 drives the large gear 582 to rotate an angle through the second shaft 584, the connecting rod 1 585 and the first shaft 583, so that the large gear 582 drives the shock absorber 4 to rotate in the opposite direction by about 90 degrees through the small gear 581 and the rotating shaft 580. In this way, the axial direction of the wire rope 42 can be rotated from perpendicular to the length direction of the adjustment seat 2 to parallel. In this way, it is restored to the state when the angle is not adjusted.

[0050] The above technical solution can rotate the axial direction of the steel wire rope 42 from parallel to the length direction of the adjustment seat 2 to perpendicular to it before adjusting the angle by setting the angle adjustment device 5 and controlling the rotation of the main shaft 54 ​​and the worm gear 55. By controlling the movement of the moving frame 53, the main shaft 54 ​​and the worm gear 55, the adjustment arm 563 can push the adjustment seat 2 upward to achieve the purpose of adjusting the angle. Since the axial direction of the steel wire rope 42 is perpendicular to the length direction of the adjustment seat 2 after the angle is adjusted, the force on the steel wire rope 42 in the axial direction is small. Therefore, in the axial direction, the steel wire rope 42 will not be significantly tilted and deformed, that is, it can be ensured that its shock absorption performance will not be reduced.

[0051] Refer to the instruction manual Figure 6-Figure 8 There are two groups of shock absorbing devices 4 on both sides of the adjustment seat 2. One side of the large gear 582 corresponding to the two groups of shock absorbing devices 4 is fixedly connected with the shaft three 586. The rotating component 58 also includes a connecting rod 2 587, and the two ends of the connecting rod 2 587 are respectively hinged with the two shafts 3 586.

[0052] It should be noted that two sets of shock absorbing devices 4 are arranged on each side, and the supporting and shock absorbing performances are good. Figure 7 and Figure 8 As shown, when the large gear 582 on the left rotates, the large gear 582 can drive the large gear 582 on the right to rotate synchronously through the second connecting rod 587, thereby achieving the purpose of all the shock absorbing devices 4 being able to rotate simultaneously.

[0053] Refer to the instruction manual Figure 3 and Fig. 9 A positioning hole 5621 is formed at one end of the slider 562 close to the push plate 564 , and a positioning pin 5641 is fixedly connected to one end of the push plate 564 close to the slider 562 . When the push plate 564 pushes the slider 562 , the positioning pin 5641 is inserted into the positioning hole 5621 .

[0054] It should be noted that when the push plate 564 pushes the slider 562 , the positioning pin 5641 is inserted into the interior of the positioning hole 5621 , which can improve the stability during pushing.

[0055] Refer to the instruction manual Figure 1 One end of the adjustment seat 2 away from the long axis 21 is fixedly connected to the support shaft 22 , and one end of the base 1 is fixedly connected to the support 11 , and the support 11 is used to support the support shaft 22 .

[0056] It should be noted that when the adjustment seat 2 is in a horizontal state, the support shaft 22 is supported on the support 11 .

[0057] Finally: The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
