Description

Technical Field

[0001] The present invention relates to the technical field of bomb hanging equipment, and in particular to a compact mechanism for realizing multi-degree-of-freedom posture adjustment. Background Art

[0002] Currently, the bomb-loading and positioning mechanisms of existing bomb-loading vehicles all utilize an external bomb-loading space design, making them less susceptible to the limitations of the loading bay. For certain main combat aircraft requiring internal bomb-loading, an external bomb-loading mechanism is susceptible to space constraints within the aircraft's internal bomb bay. This requires a lower profile and narrower width for the bomb-loading and positioning mechanism, while also requiring the operator to conveniently and flexibly manually adjust the six-degree-of-freedom posture. To accommodate smaller bomb bays or to conserve space and increase payload, the internal bomb-loading and positioning mechanism needs to be minimized while still maintaining six-degree-of-freedom positioning capabilities. Summary of the Invention

[0003] The present invention provides a compact mechanism for realizing multi-degree-of-freedom attitude adjustment, so as to solve the technical problems that when a fighter adopts an internal bomb hanging method, the bomb hanging mechanism is easily constrained by the space of the aircraft's built-in bomb bay and has a small bomb load capacity.

[0004] In order to solve the above problems, the technical solution adopted by the present invention is:

[0005] A compact mechanism for achieving multi-degree-of-freedom posture adjustment includes a supporting base plate, a gantry, a transverse support plate, a pitch plate, a slewing plate, and a bomb support rack. One end of the gantry is movably connected to the supporting base plate, and the other end is movably connected to the transverse support plate. The pitch plate is hinged above the transverse support plate. The pitch plate is movably connected to the slewing plate. The bomb support racks are installed at both ends of the slewing plate.

[0006] The supporting base plate is a rectangular frame, and four sets of linear guide rail pairs are installed inside the frame. The linear guide rail pairs are connected to the gantry.

[0007] A mounting seat 1 is installed at one end of the support base plate, and a worm drive shaft, a turbine and a trapezoidal screw 1 are installed in combination on the mounting seat 1. A nut seat 1 is screwed on the trapezoidal screw 1, and the nut seat 1 is connected to a linear guide pair 1. The nut seat 1 is internally clamped with a nut seat 2, and the nut seat 2 is screwed with the trapezoidal screw 2 and connected to the connecting rod. The connecting rod is connected to the connecting plate, and the connecting plate is connected to the transverse support plate.

[0008] A second linear guide pair is installed at both ends of the transverse support plate, the second linear guide pair is connected to the gantry, the transverse support plate is connected to the wide linear guide pair, the slider of the wide linear guide pair is connected to the second mounting seat, and a driving bevel gear and a driven bevel gear are installed in the second mounting seat.

[0009] A driving seat is provided on the transverse support plate, and a trapezoidal screw three and a double-row angular bearing are installed in the driving seat. The trapezoidal screw three is screwed with the driven bevel gear. The driving seat is hinged to the small bend connecting rod through a pin, and the small bend connecting rod is hinged to the pitch plate.

[0010] The middle position of the transverse support plate and the pitch plate is hinged through a pitch axis.

[0011] An end bearing is provided on the pitch plate, the outer ring of the end bearing is connected to the pitch plate, the inner ring of the end bearing is connected to the weighing sensor body, the upper end of the weighing sensor body is connected to the weighing sensor upper cover, and the weighing sensor upper cover is connected to the rotary plate.

[0012] The pitch plate is provided with an external tooth seat, the external tooth seat is engaged with the internal rack on the lock rod, the lock rod thread is screwed with the lock sleeve, and a quick release pin is inserted into the connection between the lock sleeve and the lock rod.

[0013] The bullet support frame is "V"-shaped, with rollers provided at both ends.

[0014] It also includes a hand crank that can be detachably connected to the worm drive shaft, the second trapezoidal lead screw and the active bevel gear.

[0015] Based on the above technical solution, the following technical effects can be produced:

[0016] 1. The present invention provides a six-degree-of-freedom attitude adjustment mechanism for the projectile, which can be manually and flexibly adjusted. This mechanism can adjust the projectile's six-degree-of-freedom attitude, including forward and backward heading, left and right heading, pitch heading, left and right heading roll, and rotation in the horizontal plane. Different bomb carriers can be flexibly switched on the mechanism to accommodate projectiles of different diameters.

[0017] 2. The functional modules of the present invention are centrally designed, and the overall structural rigidity is strong. The operator can quickly and flexibly drive the mechanism on both sides at the same time. The overall structural design improves the guarantee efficiency and versatility of bomb hanging work on different models.

[0018] 3. The overall volume of the present invention is smaller, and it is less constrained by the aircraft's ammunition bay space, while being able to increase the ammunition load accordingly. BRIEF DESCRIPTION OF THE DRAWINGS

[0032] Specifically, the support base plate 1 is a rectangular frame, and four sets of linear guide rail pairs 21 are installed inside the frame. The linear guide rail pairs 21 are connected to the gantry 2.

[0033] Specifically, a mounting seat 34 is installed on one end of the support base plate 1, and a worm drive shaft 9, a turbine 10 and a trapezoidal screw 11 are installed in combination on the mounting seat 34. A nut seat 12 is screwed on the trapezoidal screw 11, and the nut seat 12 is connected to the linear guide pair 21. The nut seat 12 is internally connected to the nut seat 2 14, and the nut seat 2 14 is screwed with the trapezoidal screw 2 13 and connected to the connecting rod 15. The connecting rod 15 is connected to the connecting plate 16, and the connecting plate 16 is connected to the transverse support plate 3.

[0034] Specifically, a second linear guide pair 22 is installed at both ends of the transverse support plate 3, the second linear guide pair 22 is connected to the gantry 2, the transverse support plate 3 is connected to the wide linear guide pair 23, the slider of the wide linear guide pair 23 is connected to the second mounting seat 35, and the driving bevel gear 17 and the driven bevel gear 19 are installed in the second mounting seat 35.

[0035] Specifically, a drive seat 26 is provided on the transverse support plate 3, and a trapezoidal screw 3 18 and a double-row angular bearing 20 are installed in the drive seat 26. The trapezoidal screw 3 18 is screwed with the driven bevel gear 19. The drive seat 26 is hinged to the small curved connecting rod 25 through the pin 24, and the small curved connecting rod 25 is hinged to the pitch plate 4.

[0036] Specifically, the middle position of the transverse support plate 3 and the pitch plate 4 is hinged through the pitch axis 8.

[0037] Specifically, an end bearing 29 is provided on the pitch plate 4, the outer ring of the end bearing 29 is connected to the pitch plate 4, the inner ring of the end bearing 29 is connected to the weighing sensor body 28, the upper end of the weighing sensor body 28 is connected to the weighing sensor upper cover 27, and the weighing sensor upper cover 27 is connected to the rotating plate 5.

[0038] Specifically, an external tooth seat 33 is provided on the pitch plate 4, and the external tooth seat 33 is engaged with the internal rack on the lock rod 32. The lock rod 32 is screwed into the lock sleeve 31 through a thread, and a quick-release pin 30 is inserted into the connection between the lock sleeve 31 and the lock rod 32.

[0039] Specifically, the bullet support frame 6 is "V"-shaped, and rollers are provided at both ends thereof.

[0040] Specifically, it also includes a hand crank 7 that can be detachably connected to the worm drive shaft 9, the trapezoidal screw 13 and the active bevel gear 17.

[0041] The working principle of the compact mechanism for realizing multi-degree-of-freedom posture adjustment of the present invention is as follows:

[0042] The working principle of longitudinal forward and backward movement adjustment is: insert the hand crank 7 into the worm drive shaft 9 and manually rotate it in the clockwise and counterclockwise directions. This drives the turbine 10, which in turn drives the trapezoidal screw 11, which in turn drives the nut seat 12. At the same time, through the gantry 2, nut seat 2 14, connecting rod 15, and connecting plate 16, the transverse support plate 3 and the entire projectile body slide back and forth along the linear guide pair 21 in the forward and backward direction of the heading. (The heading is parallel to the length of the attitude adjustment mechanism.)

[0043] The working principle of the lateral forward and backward movement adjustment: insert the hand crank 7 into any one end of the trapezoidal screw 2 13 and rotate it manually in the clockwise and counterclockwise directions, driving the nut seat 2 14 to move linearly along the left and right directions of the heading, and drive the lateral support plate 3 and the entire projectile to slide back and forth linearly along the linear guide pair 22 along the left and right directions of the heading through the connecting rod 15 and the connecting plate 16.

[0044] The working principle of pitch adjustment: insert the hand crank 7 into the synchronization rod that fits with the active bevel gear 17 and rotate it manually in the clockwise and counterclockwise directions. The active bevel gear 17 synchronously drives the driven bevel gear 19 to rotate, and at the same time spirally drives the trapezoidal screw three 18. The two ends of the trapezoidal screw three 18 simultaneously drive the double-row angular bearings 20 and the drive seat 26 to slide linearly along the wide linear guide pair 23. The drive seat 26 simultaneously pulls and pushes in two opposite directions at both ends of the pitch plate 4 through the pin 24 and the small curved connecting rod 25, so that the pitch plate 4 rotates in the clockwise and counterclockwise directions around the hinge pitch axis 8, so that all the connecting parts above the pitch plate 4 and the projectile as a whole perform heading pitch motion around the pitch axis 8.

[0045] The working principle of the rotation adjustment: manually pull out the quick-release pin 30, manually rotate the lock sleeve 31, so that the inner rack on the lock rod 32 disengages the outer gear seat 33, unlocks the slewing plate 5 relative to the pitch plate 4, and manually rotates the slewing plate 5 so that it, together with the weighing sensor cover 27, the weighing sensor body 28 and the inner ring of the end face bearing 29, rotates around the outer ring of the end face bearing 29 in a horizontal plane within ±6°, while driving the bullet holder and the bullet placed therein. The rotation angle position can be locked at any angle within the range of ±6° through the engagement of the inner rack on the lock rod 32 and the outer gear seat 33.

[0046] The working principle of roll adjustment is: manually rotate the projectile placed on the bullet support rack 6 so that the projectile rotates in a vertical circle around the roller on the bullet support rack 6.

[0047] The present invention has been described in detail above with reference to the accompanying drawings and embodiments. However, the present invention is not limited to the above embodiments. Various modifications are possible within the scope of ordinary skill in the art without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed herein, and all embodiments falling within the scope of the claims of this application are intended to be protected by the present invention.
