[0002] An existing patent (publication number: CN222134761U) discloses a tooling for aerospace irregular-shaped shells, including a platform. A disk is located on the top of the platform, and multiple rods (i) are distributed around the top circumference of the disk. A rod (ii) extends through one end of each rod (i). A connecting rod (i) is fixedly installed on the top of the disk, extending through the disk into the platform. A gear (i) is fixedly sleeved on the surface of the connecting rod (i), and a gear (ii) meshes with the surface of the gear (i). A screw is rotatably connected to the inside of the platform via a bearing. A movable component is located on the top of the screw. A base is located at the bottom of the platform, and a support rod extending into the base is fixedly installed inside the platform. A worm gear is fixedly sleeved on the surface of the support rod, and a worm meshes with the surface of the worm gear. A rotary motor (ii) is fixedly installed inside the base, and its output end is fixedly sleeved with a worm meshing with the worm gear via a coupling. However, this tooling lacks telescopic extension, cannot adapt to the processing of shells of different sizes, and cannot clamp and fix workpieces with different hole diameters. Summary of the Invention

[0003] To address the aforementioned shortcomings of existing technologies, this invention provides an aerospace-grade irregular shell tooling that can adapt to a certain degree of irregularity, enabling the positioning of at least two points inside the shell. This structure can clamp irregularly shaped shells with different apertures.

[0004] The objective of this utility model is achieved through the following technical solution:

[0005] A special-shaped aerospace housing tooling includes a circular base plate, a fixed telescopic tube, a sliding telescopic sleeve, a conical support base, a rotating top plate, a sliding pressure plate, a sliding guide rod, a spring, and an arc-shaped buckle plate. The lower part of the fixed telescopic tube is connected to the circular base plate, and the upper part of the fixed telescopic tube is adapted to the sliding telescopic sleeve. The upper part of the fixed telescopic tube is inserted into the sliding telescopic sleeve and slides within the sliding telescopic sleeve. The side of the fixed telescopic tube has multiple arc-shaped positioning slots, and the sliding telescopic sleeve has arc-shaped clearance holes. The arc-shaped positioning slots correspond to the arc-shaped clearance holes. An arc-shaped handle is connected to the outer side of the arc-shaped buckle plate, and an arc-shaped limiting plate is located inside the arc-shaped buckle plate. The arc-shaped limiting plate is adapted to the arc-shaped positioning slots and passes through the arc-shaped clearance holes to insert into the arc-shaped positioning slots. The inner side of the arc-shaped buckle plate fits against the outer side of the sliding telescopic sleeve.

[0006] The upper part of the sliding telescopic sleeve has a slide rod insertion hole. The sliding pressure plate is adapted to the sliding telescopic sleeve. The sliding pressure plate is inserted into the sliding telescopic sleeve and slides inside the sliding telescopic sleeve. The upper part of the sliding pressure plate is connected to a sliding guide rod. The sliding guide rod is adapted to the slide rod insertion hole and is inserted into the slide rod insertion hole. The sliding guide rod slides inside the slide rod insertion hole.

[0007] The spring is sleeved on the sliding guide rod, with the lower part of the spring abutting against the sliding pressure plate and the upper part of the spring abutting against the top of the sliding telescopic sleeve. The sliding telescopic sleeve has strip-shaped relief holes, and multiple strip-shaped relief holes are evenly distributed on the sliding telescopic sleeve. The side of the strip-shaped relief hole has a side connecting ear, and the side connecting ears are symmetrically arranged on both sides of the strip-shaped relief hole. Beneficial effects

[0008] 1. This utility model features a fixed telescopic tube mounted on a circular base plate. The circular base plate is installed on a workbench during use, with the fixed telescopic tube centrally fixed on it. During the processing of irregularly shaped shells, the fixed telescopic tube secures the shell to the center of the circular base plate. This prevents uneven stress on the entire device due to center-of-gravity shift during processing of irregularly shaped shells in aerospace applications, facilitating symmetrical processing and reducing load deviations in the tooling. The fixed telescopic tube is inserted into a sliding telescopic sleeve, and the telescopic length between them is fixed by an arc-shaped limiting plate. This design is suitable for processing various sizes of irregularly shaped shells. When not in use, it can be retracted to a smaller volume, saving space. During the processing of irregularly shaped shells, the telescopic length can be flexibly adjusted according to process requirements. The top plate's central sleeve is connected to symmetrical side connecting ears via a rotating shaft, allowing the rotating top plate to be mounted on the sliding telescopic sleeve and to rotate.

[0009] 2. The conical support base of this utility model is installed and fixed inside the sliding telescopic sleeve. The conical support base supports the part of the rotating top plate that extends into the sliding telescopic sleeve, limiting the maximum rotation angle of the rotating top plate. The sliding pressure plate is placed inside the sliding telescopic sleeve. The spring is guided by the sliding guide rod and supported by the sliding telescopic sleeve, applying a downward thrust to the sliding pressure plate. The sliding pressure plate pushes the part of the rotating top plate inserted into the sliding telescopic sleeve downward, causing the rotating top plate to rotate and open. The three rotating top plates rotate to support the irregular shell fitted on them. This elastic rotation structure has a large spring constant, which makes the three rotating top plates provide greater support force for the irregular shell and fix the shell. In the processing of irregular shells, this device can adapt to a certain degree of irregularity, so that at least two points inside the shell can be positioned. This structure can clamp irregular shells with different apertures. Attached Figure Description

The upper part of the fixed telescopic tube 02 is adapted to the sliding telescopic sleeve 03, and the upper part of the fixed telescopic tube 02 is inserted into the sliding telescopic sleeve 03. The sleeve 03 slides within the sleeve and the telescopic length between the two is fixed by the arc-shaped limiting plate 18. It can be used to process various sizes of irregular shells. At the same time, it can be retracted to a smaller volume when not in use, saving space. During the processing of irregular shells, the telescopic length can be flexibly adjusted according to the process requirements. The side of the fixed telescopic tube 02 has multiple arc-shaped positioning slots 04. The sliding telescopic sleeve 03 has an arc-shaped clearance hole 05.

The inside of the arc-shaped buckle 16 has an arc-shaped limiting plate 18. The arc-shaped limiting plate 18 is adapted to the arc-shaped positioning slot 04. The arc-shaped limiting plate 18 passes through the arc-shaped clearance hole 05 and is inserted into the arc-shaped positioning slot 04. The inner side of the arc-shaped buckle 16 fits against the outer side of the sliding telescopic sleeve 03. The middle sleeve 11 of the top plate is connected to symmetrical side connecting ears 09 through the rotating shaft 15, so that the rotating top plate 10 is installed on the sliding telescopic sleeve 03 and the rotating top plate 10 can rotate.

[0020] Example 2:

[0021] The sliding telescopic sleeve 03 of this utility model has a sliding rod insertion hole 07 on its upper part. The sliding pressure plate 12 is adapted to the sliding telescopic sleeve 03. The sliding pressure plate 12 is inserted into the sliding telescopic sleeve 03 and slides inside the sliding telescopic sleeve 03. The upper part of the sliding pressure plate 12 is connected to a sliding guide rod 13. The sliding guide rod 13 is adapted to the sliding rod insertion hole 07 and is inserted into the sliding rod insertion hole 07. The sliding guide rod 13 slides inside the sliding rod insertion hole 07.

[0022] Example 3:

[0023] The spring 14 described in this utility model is sleeved on the sliding guide rod 13. The lower part of the spring 14 abuts against the sliding pressure plate 12, and the upper part of the spring 14 abuts against the top of the sliding telescopic sleeve 03. The sliding telescopic sleeve 03 has a strip-shaped relief hole 08. Multiple strip-shaped relief holes 08 are evenly distributed on the sliding telescopic sleeve 03. The side of the strip-shaped relief hole 08 has a side connecting ear 09, and the side connecting ear 09 is symmetrically arranged on both sides of the strip-shaped relief hole 08.

[0024] Example 4:

[0025] The rotating top plate 10 of this invention is adapted to the strip-shaped clearance hole 08.

The conical support seat 06 is adapted to the sliding telescopic sleeve 03 and is inserted into the sliding telescopic sleeve 03. The conical support seat 06 is connected to the sliding telescopic sleeve 03 and is installed and fixed inside the sliding telescopic sleeve 03. The conical support seat 06 supports the part of the rotating top plate 10 that extends into the sliding telescopic sleeve 03 and limits the maximum rotation angle of the rotating top plate 10. The rotating top plate 10 has a top plate middle sleeve 11, and both ends of the top plate middle sleeve 11 are fitted with symmetrical side connecting ears 09. The top plate middle sleeve 11 is connected to the symmetrical side connecting ears 09 through a rotating shaft 15.

The spring 14 is guided by the sliding guide rod 13 and supported by the sliding telescopic sleeve 03. The spring 14 applies a downward pushing force to the sliding pressure plate 12. The sliding pressure plate 12 pushes the part of the rotating top plate 10 inserted into the sliding telescopic sleeve 03 downward, causing the rotating top plate 10 to rotate and open. The three rotating top plates 10 rotate to support the irregular shell fitted on them. In this elastic rotation structure, the spring 14 has a large stiffness coefficient, which makes the three rotating top plates 10 have a large supporting force on the irregular shell and fixes the shell. In the processing of irregular shells, this device can adapt to a certain degree of irregularity, so that at least two points inside the shell can be positioned.
