[0002] The docking of the tube structure is a critical task in the final assembly process, and the docking quality is crucial for the transport and launch of the projectile. For products with significant differences in projectile diameter, the projectile inside the tube is in a cantilevered state during the docking operation. In this state, the projectile may jam upon entering the tube, or even damage the projectile's surface and structural components. To ensure that the projectile's axis is coaxial with the tube structure, and to guarantee smooth projectile entry and docking quality, it is essential to design an auxiliary support fixture to support the cantilevered end of the projectile. Summary of the Invention

Detailed Implementation

[0021] The purpose of this invention is to provide an auxiliary support fixture for use inside a cylinder during the docking process, ensuring that the projectile is coaxial with the cylinder structure when it enters the cylinder, and avoiding damage to the product due to jamming during the entry process.

[0022] An auxiliary support fixture for docking within a cylinder is characterized by comprising an upper moving platform 3, a lower support body 4, a connecting shaft 5, conical wheels 6 and 7, a bidirectional connecting shaft 8, a side support plate 9, and displacement blocks 11. The bidirectional connecting shaft 8 has bidirectional threads, each threaded into a displacement block 11. The bidirectional connecting shaft 8 passes through the front and rear ends of the lower support body 4 and is fixed by the side support plate 9. Symmetrical grooves are formed on the front and rear end faces of the lower support body 4, and the side support plate 9 is inserted into these grooves and fixed to the lower support body 4 by six screws 10. Two conical wheels 6 and two conical wheels 7 are fitted onto the connecting shaft 5, with the conical wheels 7 closer to the inner side of the connecting shaft and the conical wheels 6 closer to the outer side. Bushings 12 and 13 are installed between the conical wheels. The two connecting shafts fitted with the conical wheels 6 and 7 and the bushings 12 and 13 pass through the left and right sides of the lower support body 4, and the tail ends of the connecting shafts are fixed to the lower support body 4 by nuts 20 and washers 21. The upper surface of the lower support body 4 has a groove, and the upper moving platform 3 is embedded in the groove on the upper surface of the lower support body 4. The trapezoidal boss at the bottom of the upper moving platform 3 fits tightly against the displacement block 11.

[0023] Before docking, the auxiliary support fixture is moved to the opening of the cylinder structure 1. After the cantilever end of the projectile 2 has entered the cylinder a certain distance, the feed of the projectile 2 is paused. A tool socket wrench is used to connect and tighten the end of the bidirectional connecting shaft 8. As the two displacement blocks 11 on the bidirectional connecting shaft 8 gradually approach each other, the upper moving platform 3 is vertically raised until the arc surface of the upper moving platform 3 is in close contact with the outer surface of the projectile 2. The projectile 2 continues to feed horizontally, and the auxiliary support fixture moves along the cylinder structure 1 as the projectile 2 feeds, thus providing auxiliary support for the projectile 2 inside the cylinder.

[0024] The lower support body 4 is provided with lifting grooves 17 on the left and right sides.

[0025] The lower support body 4 is provided with connecting shaft mounting holes 18 that pass through both sides.

[0026] The lower support body 4 is provided with side support plate fixing threaded holes 19 at the front and rear ends.

[0027] The side support plate 9 is provided with screw mounting holes 14 and a bidirectional connecting shaft mounting hole.

[0028] Based on the process requirements of docking and the characteristics of operation in confined space, the invention provides a simple-to-operate, reliable projectile auxiliary support fixture that can adaptively travel in a straight line inside the cylinder. By converting the rotation of the thread into vertical lifting, the specific device scheme is as follows: A cylindrical auxiliary support fixture for docking includes an upper moving platform, a lower support body, a connecting shaft, a conical wheel, a bidirectional connecting shaft, a displacement block, and a side support plate.

[0029] The upper moving platform has a rounded top surface that can fit against the outer surface of the projectile; the trapezoidal boss at the bottom has two sloping surfaces on both sides that fit against the sloping surface of the displacement block.

[0030] The lower support body has a rectangular groove at the top, allowing the bottom boss of the upper moving platform to be inserted. The front and rear end faces have centrally located grooves containing six countersunk threaded holes and one through hole, used for mounting the side support plate and fixing the bidirectional connecting shaft, respectively. Two sets of connecting shaft mounting holes are symmetrically located on the two sides; a groove in the center of each side is used for lifting.

[0031] The connecting shaft has an internal hexagonal groove at one end for easy tool installation and fastening; the other end is threaded for threaded fastening after passing through the lower support body.

[0032] The conical wheels, comprising two different diameters, are symmetrically mounted on the connecting shaft. A large conical wheel is installed in the middle of the connecting shaft, and small conical wheels are installed at both ends, with the conical wheels separated by bushings. The conical surface of the conical wheels fits tightly against the inner surface of the cylindrical structure, allowing them to travel in a straight line within the cylindrical structure.

[0033] The bidirectional connecting shaft has hexagonal ends for use with socket wrenches; the middle section is symmetrically machined into two sections with forward and reverse threads for installing displacement blocks.

[0034] The displacement block has a trapezoidal structure and a threaded through hole for connecting with the forward and reverse threads on the bidirectional connecting shaft. The two displacement blocks are installed head to head.

[0035] The side support plate has a convex shape on its side, allowing it to be embedded in the grooves on the front and rear ends of the lower support body. Six countersunk holes are symmetrically distributed on the front of the side support plate for fastening it to the lower support body; a through hole is located slightly lower on the front of the side support plate for a bidirectional connecting shaft to pass through and be fixed thereto.

[0036] Specifically, before docking, the auxiliary support fixture should be moved to the opening of the cylindrical structure. Since the upper moving platform is directly embedded in the lower support body without being fixed, when moving it to the opening of the cylindrical structure, the symmetrical grooves on the side of the lower support body must be manually lifted; do not directly lift the upper moving platform by hand to avoid the auxiliary support fixture falling and damaging the product. After the projectile's cantilever end enters the cylinder a certain distance, pause the projectile's feed. Use a socket wrench to engage and tighten the end of the bidirectional connecting shaft. As the two displacement blocks on the bidirectional connecting shaft gradually approach each other, the upper moving platform will be vertically raised until its curved surface is in close contact with the outer surface of the projectile. Continue tightening the bidirectional connecting shaft to adjust the gap between the projectile and the inner wall of the cylinder to be consistent. The projectile continues to feed horizontally, and the auxiliary support fixture moves along the cylinder while supporting the projectile, thus providing auxiliary support for the projectile inside the cylinder.

[0037] An auxiliary support fixture for docking inside a cylinder (with attachment) Figure 2 ), including mobile platforms (attached) Figure 6 7) Lower support body (attached) Figure 8 ), connecting shaft (with) Figure 4 ), conical wheel (with) Figure 4 ), bidirectional connecting shaft (with) Figure 3 ), displacement block (attached) Figure 3 ), side support plate (attached) Figure 8 ), bushings, screws, washers and nuts.

[0038] First, align the center holes of bushing 12, conical wheel 6, conical wheel 7, and bushing 13 with the mounting hole 18 of the connecting shaft 5 of the lower support body 4. Pass the connecting shaft 5 through the mounting hole on the side of the lower support body 4 and through the mounting hole at the other end. Screw the washer 21 and nut 20 into the tail of the connecting shaft 5 and tighten them. Conical wheel 7 is closer to the inner side of the connecting shaft, and conical wheel 6 is closer to the outer side of the connecting shaft. The two conical wheels 7 are separated by bushing 13, and conical wheel 6 is separated from conical wheel 7 by bushing 12. Screw the two displacement blocks 11 into the bidirectional connecting shaft respectively, and assemble the small ends of the two displacement blocks opposite each other. Pass both ends of the bidirectional connecting shaft 8 through the bidirectional connecting shaft mounting holes of the side support plate 9 respectively, and align the screw mounting holes 14 of the side support plate 9 with the fixing threaded holes 19 of the side support plate of the lower support body 4. Fix the side support plate 9 to the lower support body 4 with 6 screws 10. The bottom trapezoidal protrusion 16 of the upper moving platform 3 is embedded into the top groove of the lower support body 4, so that the inclined surfaces on both sides of the bottom trapezoidal protrusion 16 are in contact with the inclined surfaces of the displacement blocks. By using a tool socket wrench to connect and screw the end of the bidirectional connecting shaft 8, as the two displacement blocks 11 on the bidirectional connecting shaft 8 gradually approach each other, the upper moving platform 3 is vertically raised until the arc surface of the upper moving platform 3 is in close contact with the outer surface of the cantilever end of the projectile 2, thereby achieving auxiliary support for the projectile 2.

[0039] Note 1: The cylindrical structure 1 and the projectile 2 are docking objects and are not part of the invention content;

[0040] Note 2: Screw 10, nut 20, and washer 21 are standard parts.
