[0027] like Figures 1-4 As shown, the rocket shell section positioning fixture of this utility model embodiment may include...

[0028] Fixed fixture 1, there are two sets of fixed fixture 1, which include ring block 2, fixing part 3, multiple sets of adjusting blocks 4 and multiple sets of adjusting rods 5, wherein...

[0029] The ring block 2 includes a first half-ring block 211 and a second half-ring block 222. One end of the first half-ring block 21 is hinged to one end of the second half-ring block 22, and the other end of the first half-ring block 21 is connected to the other end of the second half-ring block 22 through a fastener 3. The first half-ring block 21 and the second half-ring block 22 open and close to place the rocket shell section into the tooling. The other end of the first half-ring block 21 is connected to the other end of the second half-ring block 22 through a fastener 3. When it is necessary to fix the rocket shell section, the first half-ring block 21 and the second half-ring block 22 are tightly connected through the fastener 3 to form a complete ring structure to hold the rocket shell section.

[0030] Multiple sets of adjusting blocks 4 are arranged in a ring array inside the ring block 2. The two ends of the adjusting blocks 4 extend to the two sides of the ring block 2, and each end of the adjusting blocks 4 is threadedly connected to a set of adjusting rods 5. By rotating the adjusting rods 5, the adjusting blocks 4 can be pushed to move radially within the ring block 2, thereby achieving fine adjustment of the position of the rocket shell section within the ring block 2 to accommodate rocket shell sections of different sizes and achieve higher positioning accuracy requirements.

[0031] Both ends of the adjusting block 4 are threadedly connected to a set of adjusting rods 5.

[0037] In this embodiment, the longitudinal alignment mechanism is located at the moving end of the transverse alignment mechanism. One set of fixed fixtures 1 is fixed to the surface of the transverse alignment mechanism, and another set of fixed fixtures 1 is connected to the moving end of the longitudinal alignment mechanism. Through the coordinated work of the transverse and longitudinal alignment mechanisms, the positions of the two sets of fixed fixtures 1 can be adjusted in the horizontal and vertical directions, thereby accurately positioning the rocket shell section and ensuring the positional accuracy of the rocket shell section during the assembly process.

[0038] In one embodiment of this utility model, the lateral alignment mechanism includes a movable seat 81, a lead screw bearing seat 82, a ball screw 83, and a drive motor 84. A set of fixing fixtures 1 is fixed to the surface of the movable seat 81.

[0039] The lead screw bearing housing 82 is located inside the movable seat 81. The ball screw 83 is rotatably connected to the center of the lead screw bearing housing 82. The output end of the drive motor 84 is connected to one end of the ball screw 83. The moving end of the ball screw 83 is slidably connected to the inner wall of the movable seat 81.

[0040] The longitudinal alignment mechanism includes a lifting pump 85, the cylinder of the lifting pump 85 is connected to the moving end of the ball screw 83, and another set of fixed fixtures 1 is connected to the moving end of the lifting pump 85.

[0041] In this embodiment, a set of fixed fixtures 1 is fixed to the surface of the movable seat 81. A lead screw bearing seat 82 is disposed inside the movable seat 81. A ball screw 83 is rotatably connected to the center of the lead screw bearing seat 82. The output end of the drive motor 84 is connected to one end of the ball screw 83, and the moving end of the ball screw 83 is slidably connected to the inner wall of the movable seat 81. When the drive motor 84 starts, it drives the ball screw 83 to rotate, causing the moving end of the ball screw 83 to slide on the inner wall of the movable seat 81, thereby achieving horizontal position adjustment of the fixed fixtures 1. The cylinder of the lifting pump 85 is connected to the moving end of the ball screw 83, and another set of fixed fixtures 1 is connected to the moving end of the lifting pump 85. By controlling the operation of the lifting pump 85, the vertical position adjustment of the other set of fixed fixtures 1 can be achieved. In conjunction with the lateral alignment mechanism, this completes the all-around precise positioning of the rocket shell section.

[0042] Specifically, in the actual execution process, the installation and preparation are as follows: First, install the two sets of fixed fixtures 1 on the transverse alignment mechanism and the longitudinal alignment mechanism respectively. Ensure that the fixed fixtures 1 are firmly installed and that the connections are tight and without looseness. Install the lead screw bearing seat 82 inside the movable seat 81, and then install the ball screw 83 to the lead screw bearing seat 82, ensuring that the ball screw 83 can rotate smoothly. Connect the drive motor 84 to one end of the ball screw 83, and debug the drive motor 84 to ensure that it can drive the ball screw 83 to rotate normally. Connect the cylinder of the lifting pump 85 to the movable end of the ball screw 83, and connect the other set of fixed fixtures 1 to the movable end of the lifting pump 85.

[0043] Rocket shell section positioning operation: Open the ring block 2 of the fixing fixture 1, place one end of the rocket shell section into the fixing fixture 1 on the transverse alignment mechanism, then close the ring block 2 and secure it with the fastener 3. According to the actual dimensions of the rocket shell section, use a tool to rotate the adjusting rod 5, pushing the adjusting block 4 to move within the ring block 2, so that the end piece 6 of the adjusting block 4 tightly fits the surface of the rocket shell section, making a preliminary adjustment to the position of the rocket shell section within the ring block 2. Start the drive motor 84 of the transverse alignment mechanism, and adjust the position of the fixing fixture 1 in the horizontal direction according to the positioning requirements of the rocket shell section. Then start the lifting pump 85 of the longitudinal alignment mechanism, and adjust the position of the other set of fixing fixtures 1 in the vertical direction, so that the other end of the rocket shell section accurately enters the fixing fixture 1 on the longitudinal alignment mechanism. Again, use the adjusting rod 5 to fine-tune the position of the rocket shell section within the fixing fixture 1 on the longitudinal alignment mechanism, ensuring that the rocket shell section is in a precise positioning state. After the rocket shell section is positioned, subsequent assembly operations can be performed.

[0044] In summary, the rocket shell section positioning fixture of this utility model, through the design of the fixed fixture 1 and the precise alignment device 8, can achieve high-precision positioning and flexible adjustment of the rocket shell section, meet the strict requirements for shell section positioning in the rocket manufacturing process, and improve the quality and efficiency of rocket assembly.
