Description

Technical Field

[0001] The present application relates to the field of rocket assembly equipment, and in particular to a rocket fairing frame docking tool and a rocket fairing frame. Background Art

[0002] During the assembly process of the rocket, the half-cover of the fairing needs to be fixed on the fairing jig first. In order to achieve the docking of the two half-covers in the fairing, it is necessary to use a variety of docking tools installed on the fairing jig to fine-tune the shape and posture of the half-cover so that the two half-covers can be assembled. In the prior art, when fine-tuning the shape and posture of the half-cover, it is necessary to push or pull the joint part of the half-cover, and after repeated pushing or pulling, the shape and posture of the half-cover can meet the requirements for assembly with the other half-cover. At present, the pushing and pulling of the joint part of the half-cover is completed by two different sets of docking tools. At the same time, the same part of the half-mask is either pulled or pushed. When pulling is needed, the outward pulling docking tooling is replaced, and when pushing is needed, the inward pushing docking tooling is replaced. However, the pushing and pulling operations are often performed alternately, and the outward pulling docking tooling and the inward pushing docking tooling need to be frequently replaced. This switching is time-consuming and laborious, which greatly affects the shape and posture adjustment efficiency of the half-mask.

[0003] In addition to the above-mentioned shortcomings, the docking tooling has some shortcomings that cannot be ignored. There is a docking hole on the half-hood. When the half-hood is pulled outward, the docking tooling needs to be connected to the docking hole. However, due to the positioning accuracy problem when processing the docking hole, the installation accuracy problem when installing the docking tooling, the large deformation of the half-hood caused by the large size of the half-hood, and the deformation of the fairing frame, the connection difficulty of the docking tooling and the docking hole is greatly increased, which seriously affects the docking efficiency of the docking tooling and the docking hole, and further affects the shape and attitude adjustment efficiency of the half-hood. Summary of the invention

[0004] In order to solve the above problems, the present application provides a rocket fairing frame docking tooling and a rocket fairing frame, which are cleverly designed and simple in structure. The present application has both push and pull functions, avoiding frequent switching between docking tools with push or pull functions, and greatly improving the efficiency of fine-tuning the half-cover. In addition, the docking joint can be universally rotated relative to the adjustment screw, reducing the difficulty of docking the docking tooling and the docking hole. In addition, the docking joint and the adjustment screw are detachably connected, which facilitates the removal of the docking joint from the half-cover. The technical solutions adopted by the present application are as follows:

The docking joint can adapt to larger position errors.

In addition, the detachable connection between the docking joint and the adjusting screw facilitates the installation of the docking joint into the docking hole, that is, the docking joint is first installed into the docking hole, and then connected to the adjusting screw.

[0047] In this embodiment, reference Figure 4-Figure 9 Specifically, the ball-socket-ball-head connection pair 4 includes a ball socket 5, a ball head 6, a ball 7 and a locking nut 8; the ball socket 5 is provided at one end of the butt joint 3 close to the adjusting screw 2, and the ball head 6 is provided at one end of the adjusting screw 2 close to the butt joint 3; a plurality of accommodating holes 9 are provided at intervals along the circumferential direction at one end of the butt joint 3 provided with the ball socket 5; a driving inclined surface 10 is provided in the locking nut 8, the aperture of the locking nut 8 is not smaller than the ball head 6, and the locking nut 8 will not directly hinder the movement of the ball head 6 relative to the locking nut 8, and the locking nut 8 is screwed to the end of the butt joint 3 provided with the ball socket 5. The ball 7 is arranged in the accommodating hole 9 and is located in the hole of the locking nut 8; when the locking nut 8 is screwed to make the driving inclined surface 10 squeeze the ball 7, the part of the ball 7 exposed in the accommodating hole 9 and located in the ball socket 5 will squeeze the ball head 6 in the ball socket 5 and restrict the ball head 6 in the ball socket 5 to realize the universal hinge between the docking joint 3 and the adjusting screw 2; when the locking nut 8 is screwed to make the driving inclined surface 10 move away from the ball 7, the ball 7 releases the restriction on the ball head 6, and the ball head 6 can be separated from the ball socket 5, so that the docking joint 3 and the adjusting screw 2 can be separated.

[0048] In other embodiments, the ball-socket-ball-head connection pair 4 includes a ball socket 5, a ball head 6, a ball 7 and a locking nut 8; the ball head 6 is provided at one end of the docking joint 3 close to the adjusting screw 2, and the ball socket 5 is provided at one end of the adjusting screw 2 close to the docking joint 3; the end of the adjusting screw 2 provided with the ball socket 5 is provided with a plurality of accommodating holes 9 at intervals along the circumferential direction; a driving inclined surface 10 is provided in the locking nut 8, the aperture of the locking nut 8 is not smaller than the ball head 6, the locking nut 8 will not directly hinder the movement of the ball head 6 relative to the locking nut 8, the locking nut 8 can be separated from the ball head 6, and the locking nut 8 is threadedly connected to the adjusting screw 2 One end of the ball socket 5 is provided, and the ball 7 is arranged in the accommodating hole 9 and is located in the hole of the locking nut 8; when the locking nut 8 is screwed to make the driving inclined surface 10 squeeze the ball 7, the part of the ball 7 exposed in the accommodating hole 9 and located in the ball socket 5 will squeeze the ball head 6 in the ball socket 5 and restrict the ball head 6 in the ball socket 5, so as to realize the universal hinge of the docking joint 3 and the adjusting screw 2; when the locking nut 8 is screwed to make the driving inclined surface 10 away from the ball 7, the ball 7 releases the restriction on the ball head 6, and at this time the ball head 6 can be separated from the ball socket 5, so that the docking joint 3 and the adjusting screw 2 can be separated.

[0049] It is worth noting that, in one embodiment, the ball-socket-ball-head connection pair 4 includes a ball socket 5, a ball head 6, and a locking nut 8. Compared with the aforementioned embodiment, this embodiment saves the ball 7 and does not need to set the accommodating hole 9; one of the ball socket 5 and the ball head 6 is arranged at the end of the docking joint 3 close to the adjusting screw 2, and the other is arranged at the end of the adjusting screw 2 close to the docking joint 3; a spherical surface adapted to the ball head 6 is arranged in the locking nut 8, and the aperture of the locking nut 8 is smaller than the ball head 6, that is, the locking nut 8 is sleeved on the end of the docking joint 3 or the adjusting screw 2 where the ball head 6 is arranged, and the locking nut 8 cannot be separated from the ball head 6; the locking nut 8 is threadedly connected to the end of the docking joint 3 or the adjusting screw 2 where the ball socket 5 is arranged. By screwing the locking nut 8, the spherical surface can abut against the ball head 6 in the ball socket 5 and can confine the ball head 6 in the ball socket 5, so as to realize the universal hinge between the docking joint 3 and the adjusting screw 2; by screwing the locking nut 8 in the opposite direction, the locking nut 8 and the docking joint 3 or the end of the adjusting screw 2 provided with the ball socket 5 can be released from the threaded connection, and the docking joint 3 and the adjusting screw 2 can be separated.

[0050] It is easy to understand that the docking tooling 18 of the rocket fairing frame has both push and pull functions, which avoids frequent switching between docking tools with push or pull functions, and greatly improves the efficiency of fine-tuning the half-cover. In addition, the ball-socket ball head connection pair 4 is used to connect the docking joint 3 and the adjusting screw 2, so that the docking joint 3 can be universally rotated relative to the adjusting screw 2. On the one hand, it reduces the difficulty of docking between the docking tooling and the docking hole, and on the other hand, it avoids the rotation of the docking joint 3 driven by the screwing of the adjusting screw 2, so that the connection between the docking joint 3 and the docking hole on the fairing will not be affected when the adjusting screw 2 is screwed. In addition, the detachable connection between the docking joint 3 and the adjusting screw 2 facilitates the installation of the docking joint 3 into the docking hole, that is, the docking joint 3 is first installed in the docking hole, and then connected to the adjusting screw 2, and it is also convenient for the docking joint 3 to be removed from the docking hole, that is, the docking joint 3 is first separated from the adjusting screw 2, and then the docking joint 3 is separated from the docking hole.

[0051] refer to Figure 2-Figure 5 For the embodiment in which the aperture of the locking nut 8 is not smaller than the ball head 6, in one embodiment, one of the ball socket 5 and the ball head 6 is provided at one end of the docking joint 3 close to the adjusting screw 2, and the other is provided at one end of the adjusting screw 2 close to the docking joint 3. A limiting member 11 is provided at the end of the docking joint 3 or the adjusting screw 2 where the ball socket 5 is provided. The limiting member 11 is used to limit the locking nut 8 to the end of the docking joint 3 or the adjusting screw 2 where the ball socket 5 is provided, so as to prevent the locking nut 8 from falling off from the end of the docking joint 3 or the adjusting screw 2 where the ball socket 5 is provided.

[0052] Specifically, the stopper 11 may be a screw, which is inserted into the end of the butt joint 3 or the adjusting screw 2 provided with the ball socket 5, and the insertion direction of the screw is preferably perpendicular to the butt joint 3 or the adjusting screw 2. It should be noted that the screw should not enter or exit the ball socket 5, so as not to affect the fit between the ball head 6 and the ball socket 5. In other embodiments, the stopper 11 may also be a pin.

[0053] refer to Figure 2-Figure 5 In one embodiment, the limiting member 11 is a retaining spring, and one end of the joint 3 or the adjusting screw 2 having the ball socket 5 is provided with a retaining groove, and the retaining spring is clamped in the retaining groove.

[0054] refer to Figure 2-Figure 5 In one embodiment, the fixing assembly further includes a fixing seat 12, the fixing block 1 is rotatably disposed on the fixing seat 12, the rotating shaft of the fixing block 1 is coplanar and perpendicular to the axis of the adjusting screw 2, and the fixing seat 12 is suitable for being installed on the fairing frame.

[0055] It is understandable that there are many ways to achieve the rotational connection between the fixed block 1 and the fixed seat 12, and one of them is listed below: the fixed block 1 is provided with a first pin shaft hole on two opposite sides, the fixed seat 12 is provided with a clearance groove, and the second pin shaft hole is provided with a second pin shaft hole on two opposite sides of the clearance groove. The fixed block 1 is arranged in the clearance groove, and the second pin shaft hole corresponds to the position of the first pin shaft hole, and a pin shaft is inserted in the first pin shaft hole and the corresponding second pin shaft hole.

[0056] It is easy to understand that by rotatably setting the fixed block 1 on the fixed seat 12, the adjusting screw 2 can rotate with the fixed block 1. In addition, combined with the universal rotation between the adjusting screw 2 and the docking joint 3, the spatial range that the docking joint 3 can reach is further increased, and the adaptability of the docking joint 3 to the position error between the docking hole and the docking joint 3 is improved, and the docking joint 3 can adapt to larger position errors. On the basis of the above, the rotating shaft of the fixed block 1 is coplanar and perpendicular to the axis of the adjusting screw 2, which can improve the convenience and accuracy of adjusting the position of the docking joint 3 through the adjusting screw 2.

[0057] refer to Figure 2-Figure 5 In one embodiment, a waist-shaped hole 13 is provided on the fixing seat 12, and the fixing seat 12 is suitable for being installed on the fairing frame through the cooperation of the connecting piece and the waist-shaped hole 13. By providing the waist-shaped hole 13 on the fixing seat 12, the position of the fixing seat 12 on the fairing frame can be adjusted, which further increases the spatial range that the docking joint 3 can reach, and enhances the adaptability of the docking joint 3 to the position error between the docking hole and the docking joint 3, so that the docking joint 3 can adapt to a larger position error.

[0058] It is understandable that the connection between the docking joint 3 and the docking hole on the fairing is mainly to realize the joint seam part of the fairing being pulled outward. In order to realize the connection between the docking joint 3 and the docking hole, the specific form of the docking joint 3 should be compatible with the specific form of the docking hole. For example, if the docking hole is a threaded hole, the end of the docking joint 3 away from the adjusting screw 2 should be provided with an external thread. When the end of the docking joint 3 away from the adjusting screw 2 is provided with an external thread, that is, when the docking joint 3 and the docking hole are threaded, it is preferred to set a screwing position 15 on the docking joint 3. The screwing position 15 can specifically be two mutually parallel planes arranged on opposite sides of the docking joint 3, or it can be the cylindrical surface of a regular hexagonal prism. By setting the screwing position 15, a force point is provided for screwing the docking joint 3, which is convenient for disassembling and assembling the docking joint 3 with the help of tools (fixed wrench, movable wrench).

[0059] refer to Figure 2-Figure 5 In one embodiment, a screwing handle 14 is provided at one end of the adjusting screw 2 away from the docking head 3. By providing the screwing handle 14, the convenience of screwing the adjusting screw 2 is improved.

[0060] refer to Figure 2-Figure 5 In one embodiment, a top screw 16 is provided on the fixing block 1, and the head of the top screw 16 can penetrate into the first through hole and cooperate with the thread groove of the adjusting screw 2. By providing the top screw 16 on the fixing block 1, on the one hand, the top screw 16 can play the role of an internal thread, and there is no need to provide an internal thread in the first through hole. On the other hand, by adjusting the depth of the top screw 16, the adjusting screw 2 can be locked to prevent the adjusting screw 2 from being accidentally screwed. In other embodiments, the top screw 16 may not be provided, but an internal thread may be provided in the first through hole, and the adjusting screw 2 is adapted to the internal thread of the first through hole.

[0061] refer to Figure 1-Figure 5 The present application also provides a rocket fairing jig, including a jig frame body 17 and the aforementioned rocket fairing jig docking tool 18, wherein the rocket fairing jig docking tool 18 is installed on the jig frame body 17. The specific structure of the rocket fairing jig docking tool 18 refers to the aforementioned embodiment. Since the present rocket fairing jig adopts the technical solution of the aforementioned embodiment, it at least has the beneficial effects brought by the technical solution of the aforementioned embodiment, which will not be described one by one here.

[0062] It should be noted that the above embodiments can be freely combined as needed. The above are only preferred implementations of the present application. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles of the present application, and these improvements and modifications should also be regarded as the protection scope of the present application.
