DETAILED DESCRIPTION

[0021] The purpose of the present invention is to provide an auxiliary support tooling for use in a barrel during a docking process, to ensure that the projectile is coaxial with the barrel structure when entering the barrel, and to avoid damage to the product due to jamming during the barrel entering process.

[0022] An auxiliary support tool for docking in a cylinder, characterized in that it includes an upper moving platform 3, a lower support body 4, a connecting shaft 5, a conical wheel 6, a conical wheel 7, a bidirectional connecting shaft 8, a side support plate 9, and a displacement block 11. The bidirectional connecting shaft 8 has a bidirectional thread, and each displacement block 11 is screwed into it; 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 opened on the front and rear end surfaces of the lower support body 4, and the side support plate 9 is installed in the grooves and fixed to the lower support body 4 by 6 screws 10. Two conical wheels 6 and two conical wheels 7 are sleeved on the connecting shaft 5, the conical wheel 7 is close to the inner side of the connecting shaft, and the conical wheel 6 is close to the outer side of the connecting shaft, and a sleeve 12 and a sleeve 13 are installed between the conical wheels. Two connecting shafts sleeved with the conical wheel 6, the conical wheel 7 and the sleeve 12 and the sleeve 13 pass through the left and right sides of the lower support body 4, and the tail end of the connecting shaft is fixed to the lower support body 4 by a nut 20 and a washer 21. A groove is formed on the upper end surface of the lower support body 4, and the upper moving platform 3 is embedded in the groove on the upper end surface of the lower support body 4. The trapezoidal boss at the bottom of the upper moving platform 3 is tightly fitted with the displacement block 11.

[0023] Before docking, lift the auxiliary support tooling to the mouth of the barrel structure 1. After the cantilever end of the projectile 2 enters a certain distance into the barrel, stop feeding the projectile 2, use a tool socket wrench to connect and screw with the end of the two-way connecting shaft 8, and as the two displacement blocks 11 on the two-way connecting shaft 8 gradually approach, the upper moving platform 3 is lifted vertically 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 tooling moves along the barrel structure 1 as the projectile 2 feeds, realizing auxiliary support for the projectile 2 in the barrel.

[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 penetrating through both sides.

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

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

[0028] According to the process requirements of docking and the characteristics of limited space operations, the invention provides a projectile auxiliary support tooling that is simple to operate and can adaptively move reliably in a straight line in a barrel. The specific device scheme is as follows: an in-barrel auxiliary support tooling for docking, comprising an upper moving platform, a lower supporting body, a connecting shaft, a conical wheel, a bidirectional connecting shaft, a displacement block, and a side support plate.

[0029] The upper movable platform has an arc surface at the top, which can fit with the outer surface of the projectile; the inclined surfaces on both sides of the trapezoidal boss at the bottom are used to fit with the inclined surfaces of the displacement block.

[0030] The lower support body has a rectangular groove on the top to fit the boss at the bottom of the upper moving platform. The front and rear end surfaces have a groove in the middle, and the groove has six countersunk threaded holes and a through hole, which are used to install the side support plate and fix the two-way connecting shaft. Two sets of connecting shaft mounting holes are symmetrically opened on the two sides; a groove is opened in the center of the side for lifting.

[0031] One end of the connecting shaft is processed into a hexagonal groove to facilitate tool installation and tightening; the other end is provided with a thread for thread tightening after passing through the lower support body.

[0032] The conical wheels include two different diameters and are symmetrically mounted on the connecting shaft. A large conical wheel is mounted in the middle of the connecting shaft, and small conical wheels are mounted at both ends. The conical wheels are separated by shaft sleeves. The conical surface of the conical wheel fits tightly with the inner surface of the cylindrical structure, and can move in a straight line in the cylindrical structure.

[0033] The two ends of the bidirectional connecting shaft are external hexagonal and are used for screwing with a socket wrench; the middle part is symmetrically processed into two sections of forward and reverse threads for installing the displacement block.

[0034] The displacement block is a trapezoidal structure, and a threaded through hole is opened on the trapezoidal block 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 is convex and can 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 with the lower support body; a through hole is provided at the lower front of the side support plate for a two-way connecting shaft to pass through for support and fixation.

[0036] Specifically, before docking, first lift the auxiliary support tooling to the mouth of the cylinder structure. Since the upper moving platform is directly embedded in the lower support body and is not fixed, when lifting it to the mouth of the cylinder structure, you must lift the symmetrical grooves on the side of the lower support body by hand, and do not directly lift the upper moving platform by hand to avoid the auxiliary support tooling from falling and damaging the product. After the cantilever end of the projectile enters the cylinder for a certain distance, stop feeding the projectile, use a tool socket wrench to connect the end of the two-way connecting shaft and screw it. As the two displacement blocks on the two-way connecting shaft gradually approach, lift the upper moving platform vertically until the arc surface of the upper moving platform is in close contact with the outer surface of the projectile. By continuing to screw the two-way connecting shaft, adjust until the gap between the projectile and the inner wall of the cylinder is consistent. The projectile continues to feed horizontally, and the auxiliary support tooling moves along the cylinder while supporting the projectile as it feeds, thereby realizing auxiliary support of the projectile in the cylinder.

[0037] An auxiliary support tool for butt joint in a cylinder (attached Figure 2 ), including the upper mobile platform (with Figure 6 , 7) Lower support body (attached Figure 8 )、Connecting shaft (attached 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 the sleeve 12, the conical wheel 6, the conical wheel 7, and the sleeve 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 of the connecting shaft 5 on the side of the lower support body 4, and screw the washer 21 and the nut 20 into the tail of the connecting shaft 5 and tighten. The conical wheel 7 is close to the inside of the connecting shaft, and the conical wheel 6 is close to the outside of the connecting shaft. The two conical wheels 7 are separated by the sleeve 13, and the conical wheels 6 and 7 are separated by the sleeve 12. Screw the two displacement blocks 11 into the two-way connecting shaft respectively, and assemble the small ends of the two displacement blocks relative to the small ends. Pass the two ends of the two-way connecting shaft 8 through the two-way 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 side support plate fixing threaded holes 19 of the lower support body 4, and fix the side support plate 9 to the lower support body 4 with 6 screws 10. The trapezoidal boss 16 at the bottom of the upper moving platform 3 is inserted into the top groove of the lower supporting body 4, so that the inclined surfaces on both sides of the trapezoidal boss 16 fit with the inclined surfaces of the displacement block. By using a socket wrench to sleeve and screw with the end of the two-way connecting shaft 8, as the two displacement blocks 11 on the two-way connecting shaft 8 gradually approach, the upper moving platform 3 is vertically lifted 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 realizing auxiliary support for the projectile 2.

[0039] Note 1: The cylinder structure 1 and the projectile 2 are docking objects and do not belong to the content of the invention;

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