Abstract
Description
Technical Field
[0001] This utility model relates to an assembly and debugging device, and more particularly to an assembly and debugging device for a fixed-wing inertial navigation system component. Background Technology
[0002] The fixed-wing inertial navigation system component assembly and debugging device is a device used for assembling and debugging components of a fixed-wing inertial navigation system. Chinese utility model patent application number 201920778312.3 discloses an inertial navigation equipment installation and calibration device for aircraft. This device "adjusts the relative position of the inertial navigator and the aircraft mounting platform using four miniature hydraulic cylinders, achieving a high degree of automation and simple operation, overcoming the problem of high adjustment difficulty during the installation and debugging phase of inertial navigation equipment." However, controlling the position of the inertial navigator using four miniature hydraulic cylinders is not easy. Based on the principle of "three points determining a plane," using four miniature hydraulic cylinders for adjustment increases the control difficulty. Furthermore, this device has high requirements for the installation position of the aircraft mounting platform; if the placement or mounting surface is uneven, it will interfere with the debugging results, raising the usage requirements and highlighting the shortcomings of the existing technology. Utility Model Content
[0003] The purpose of this invention is to provide a fixed-wing inertial navigation system component assembly and debugging device to solve the technical problems of high control difficulty and high usage requirements.
[0004] To achieve the above objectives, the present invention adopts the following technical solution:
[0005] A fixed-wing inertial navigation system component assembly and debugging device includes a base, mounting ears, mounting holes, a guide cylinder, a ball joint rod, a first support base, a top plate, positioning holes, and a telescopic mechanism. The bottom of the base is horizontal and triangular in shape. Three mounting ears are fixed at equal angles around the circumference of the base, and each mounting ear has a mounting hole extending vertically. A vertical guide cylinder is fixed in the middle of the base, and a ball joint rod is slidably connected to the guide cylinder. The ball joint rod has a ball joint at its upper part that is rotatably connected to the first support base. A top plate is fixed at the top of the first support base, and multiple positioning holes for assembling inertial navigation system components extend vertically through the top of the top plate. Three vertical telescopic mechanisms are fixed at equal angles around the top of the base, and the bottom of the base is horizontal. The telescopic parts of the telescopic mechanisms can contact and separate from the bottom of the top plate.
[0006] Based on the above technical solution, the telescopic mechanism includes a support member, a second ball-head rod, a second support seat, and a first handwheel. Three vertical support members are installed at equal angles around the circumference of the base. Each support member is threadedly connected to a vertical second ball-head rod. The top ball head of each second ball-head rod is spherically rotatably connected to a second support seat, and a first handwheel is coaxially fixed to each. When the second ball-head rod rotates forward and backward, it can move up and down along the support member. Each second support seat is made of magnetic material, and the top plate is made of a material that can be magnetically attracted. The second support seat can fit and contact the bottom end of the top plate to achieve magnetic attraction.
[0007] Based on the above technical solution, the support component includes a first support cylinder, a second support cylinder, a screw cylinder, a second handwheel, and a guide ring. Three vertical first support cylinders are fixed at equal angles around the circumference of the base. A second support cylinder is coaxially rotatably connected to the outside of each first support cylinder. A screw cylinder is coaxially threaded inside each first support cylinder. The screw cylinder is coaxially threaded to a second ball joint rod. A second handwheel is coaxially fixed to the outside of each second support cylinder, and a guide ring is coaxially fixed to the upper part of each second support cylinder. Each guide ring is axially slidably connected to the screw cylinder. The telescopic mechanism also includes a locking mechanism, which can brake or de-brake the second support cylinder.
[0008] Based on the above technical solution, the locking mechanism includes a rubber cylinder, a third support cylinder, an adjusting disc, a protrusion, a sliding plate, a roller, a rubber block, a gear ring, a fourth support cylinder, a tightening screw, and a third handwheel. A rubber cylinder is coaxially fixed to the outside of the guide cylinder and rotatably connected to the third support cylinder. An adjusting disc is coaxially fixed to the outside of the third support cylinder. Three protrusions are fixed at equal angles on the outer circumference of each adjusting disc. Three sliding plates are horizontally slidably connected at equal angles on the circumference of the base. Each sliding plate is rotatably connected to a roller, and a roller is fixed to the end furthest from the guide cylinder. The rubber block and the roller can roll and rub against the outer circumference and protrusion of the adjustment disc. The bottom outer wall of each of the second support cylinders is coaxially fixed with a toothed ring. When the roller rolls and rubs against the protrusion, the rubber block can squeeze and contact the toothed ring to achieve braking. When the roller rolls and rubs against the outer circumference of the adjustment disc, the rubber block separates from the toothed ring to achieve non-braking. The outer wall of the third support cylinder is radially fixed with a fourth support cylinder. Each of the fourth support cylinders is coaxially threaded with a tightening screw. The tightening screw can press against the outer wall of the rubber cylinder and is coaxially fixed with a third handwheel.
[0009] Based on the above technical solution, a ball head seat is fixed at the bottom of the screw cylinder, and the ball head part at the bottom of the ball head seat is spherically rotatably connected to a third support seat. The bottom of the third support seat is horizontal and made of magnetic material. The first support cylinder runs through the base vertically. The third support seat can be stored inside the first support cylinder and can extend from the bottom of the first support cylinder.
[0010] Compared with the prior art, the present invention has the following advantages: The present invention uses fasteners such as bolts to fix the base through the mounting holes, thereby limiting the position of the base. The fixed-wing inertial navigation system components are placed or installed using the positioning holes. Then, by controlling the three telescopic mechanisms to extend and retract at different times, the top plate can be lifted to different degrees, so that the top plate presents different angles. This enables the assembly and debugging of the fixed-wing inertial navigation system components, reducing the difficulty of control.
[0011] Before fixing the base, if the mounting surface or placement surface is uneven, first release the locking mechanism from locking the second support cylinder, and then manually rotate the second handwheel to raise and lower the screw cylinder, thereby raising and lowering the ball head seat and the third support seat. When the third support seat extends from the bottom of the first support cylinder, it can make contact with the mounting surface or placement surface, thus providing three-point support and reducing usage requirements.

[0017] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.
[0018] like Figures 1-4As shown, a fixed-wing inertial navigation system component assembly and debugging device includes a base 1, mounting ears 2, mounting holes 3, a guide cylinder 4, a ball joint rod 5, a first support seat 6, a top plate 7, positioning holes 8, and a telescopic mechanism. The bottom of the base 1 is horizontal and triangular. Three mounting ears 2 are fixed at equal angles around the circumference of the base 1. Each mounting ear 2 has mounting holes 3 penetrating vertically. A vertical guide cylinder 4 is fixed in the middle of the base 1. The ball joint rod 5 is slidably connected to the guide cylinder 4. The ball joint rod 5 is spherically rotatably connected to the first support seat 6 at its upper ball joint. The top plate 7 is fixed at the top of the first support seat 6. The top plate 7 has multiple positioning holes 8 penetrating vertically for assembling inertial navigation system components. Three vertical telescopic mechanisms are fixed at equal angles around the top circumference of the base 1, and the bottom is horizontal. The telescopic parts of the telescopic mechanisms can contact and separate from the bottom of the top plate 7.
[0019] The base 1 is fixed by fasteners such as bolts through the mounting holes 3, thereby limiting the position of the base 1. The components of the fixed-wing inertial navigation system are placed or installed using the positioning holes 8. Then, by controlling the three telescopic mechanisms to extend and retract at different times, the top plate 7 can be lifted to different degrees, so that the top plate 7 presents different angles, thereby realizing the assembly and debugging of the components of the fixed-wing inertial navigation system.
[0020] The telescopic mechanism includes a support member, a second ball-head rod 11, a second support seat 12, and a first handwheel 13. Three vertical support members are installed at equal angles around the circumference of the base 1. Each support member is threadedly connected to a vertical second ball-head rod 11. The top ball head of each second ball-head rod 11 is spherically rotatably connected to a second support seat 12, and a first handwheel 13 is coaxially fixed to each. When the second ball-head rod 11 rotates forward and backward, it can move up and down along the support member. Each second support seat 12 is made of magnetic material. The top plate 7 is made of a material that can be magnetically attracted. The second support seat 12 can fit and contact the bottom end of the top plate 7 to achieve magnetic attraction.
[0021] Manually rotating the first handwheel 13 allows the second ball joint 11 to rotate in both directions, enabling the second support base 12 to move up and down, thereby lifting the top plate 7 to varying degrees. The magnetic attraction between the second support base 12 and the top plate 7 prevents accidental circumferential rotation of the top plate 7 and the first support base 6, ensuring accurate assembly. Manually rotating the top plate 7 also allows for active adjustment of the position of the positioning hole 8, achieving the effect of assembly and debugging.
[0022] The support components include a first support cylinder 14, a second support cylinder 15, a screw cylinder 16, a second handwheel 17, and a guide ring 18. Three vertical first support cylinders 14 are fixed at equal angles around the circumference of the base 1. A second support cylinder 15 is coaxially rotatably connected to the outside of each first support cylinder 14. A screw cylinder 16 is coaxially threaded into the inside of each first support cylinder 14. The screw cylinder 16 is coaxially threaded to a second ball joint rod 11. A second handwheel 17 is coaxially fixed to the outside of each second support cylinder 15, and a guide ring 18 is coaxially fixed to the upper part of each. Each guide ring 18 is axially slidably connected to a screw cylinder 16. The telescopic mechanism also includes a locking mechanism, which can brake or de-brake the second support cylinder 15.
[0023] When the locking mechanism brakes the second support cylinder 15, the second ball joint rod 11 can be adjusted by manually rotating the first handwheel 13. When the locking mechanism does not brake the second support cylinder 15, the second handwheel 17 can be manually rotated to drive the screw cylinder 16 to rotate through the guide ring 18, thereby adjusting the height of the second ball joint rod 11 relative to the base 1, so that the top plate 7 can present different heights and angles.
[0024] The locking mechanism includes a rubber cylinder 20, a third support cylinder 21, an adjusting disc 22, a protrusion 23, a sliding plate 24, a roller 25, a rubber block 26, a gear ring 27, a fourth support cylinder 28, a tightening screw 29, and a third handwheel 30. The rubber cylinder 20 is coaxially fixed to the outside of the guide cylinder 4 and rotatably connected to the third support cylinder 21. An adjusting disc 22 is coaxially fixed to the outside of the third support cylinder 21. Three protrusions 23 are fixed at equal angles on the outer circumference of each adjusting disc 22. Three sliding plates 24 are horizontally slidably connected at equal angles on the circumference of the base 1. Each sliding plate 24 is rotatably connected to a roller 25, and a rubber block 26 is fixed to the end furthest from the guide cylinder 4. The roller 25 can roll and rub against the outer circumference of the adjusting disc 22 and the protrusion 23. The bottom outer wall of each of the second support cylinders 15 is coaxially fixed with a toothed ring 27. When the roller 25 rolls and rubs against the protrusion 23, the rubber block 26 can press and contact the toothed ring 27 to achieve braking. When the roller 25 rolls and rubs against the outer circumferential wall of the adjusting disc 22, the rubber block 26 separates from the toothed ring 27 to achieve non-braking. The outer wall of the third support cylinder 21 is radially fixed with a fourth support cylinder 28. Each of the fourth support cylinders 28 is coaxially threaded with a tightening screw 29. The tightening screw 29 can press against the outer wall of the rubber cylinder 20 and is coaxially fixed with a third handwheel 30.
[0025] When the tightening screw 29 is not pressed against the outer wall of the rubber cylinder 20, manually turning the tightening screw 29 will cause the third support cylinder 21 and the adjusting plate 22 to rotate, thereby causing the adjusting plate 22 or the protrusion 23 to contact the roller 25, thus controlling whether the rubber block 26 and the toothed ring 27 are pressed together, and thus controlling whether the third support cylinder 21 is braked. After adjustment, rotating the third handwheel 30 will tighten the tightening screw 29 against the rubber cylinder 20, thereby achieving limit control of the third support cylinder 21, the adjusting plate 22 and the protrusion 23, that is, ensuring the braking of the second support cylinder 15.
[0026] The bottom of the screw cylinder 16 is fixed with a ball head seat 31. The ball head part at the bottom of the ball head seat 31 is spherically rotatably connected to a third support seat 32. The bottom of the third support seat 32 is horizontal and made of magnetic material. The first support cylinder 14 runs vertically through the base 1. The third support seat 32 can be stored inside the first support cylinder 14 and can extend from the bottom of the first support cylinder 14.
[0027] Before fixing the base 1, if the mounting surface or placement surface is uneven, first release the locking mechanism from locking the second support cylinder 15, and then manually rotate the second handwheel 17 to raise and lower the screw cylinder 16, thereby raising and lowering the ball head seat 31 and the third support seat 32. When the third support seat 32 extends from the bottom of the first support cylinder 14, it can contact the mounting surface or placement surface, thus providing three-point support and reducing usage requirements.
[0028] The above description is a preferred embodiment of the present utility model. For those skilled in the art, any changes, modifications, substitutions and variations made to the implementation methods without departing from the principles and spirit of the present utility model, based on the teachings of the present utility model, still fall within the protection scope of the present utility model.
