[0004] The traditional disassembly method of special-shaped shells is to fix one end first and then directly separate the shells. This disassembly method, on the one hand, the fixing structure cannot match various special-shaped shells well, resulting in unstable fixation and damage to the special-shaped shells during disassembly. Shell and its internal components; on the other hand, direct separation will cause destructive separation due to uneven force, and the huge impact force during separation is likely to cause damage to special-shaped shells and internal components or instruments

The invention discloses an expandable dismounting device for a special-shaped shell with interference fit, comprising a dismantling assembly (1), a fixing assembly (3) and a load-bearing assembly (4), and the fixing assembly (3) includes a special-shaped unloading block (303), fixed support (301) and fixed rod (302), load-bearing assembly (4) comprises dismounting support (401), threaded bolt (403) and dismounting rod (402), dismounting rod (402) is several one, uniformly distributed along the circumference, one end of which is fixed on the dismounting support (401), and the other end is threadedly connected with the threaded bolt (403). The dismounting assembly (1) includes an inner square wrench handle (101) and a ball screw (102), the ball screw (102) passes through the threaded hole of the fixing support (301), and engages with the light hole of the dismounting support (401). The invention also discloses an expandable method for disassembling the special-shaped casing with interference fit. The expandable interference fit dismounting device of the special-shaped shell of the present invention realizes uniform stress for fixing and dismounting.
Description
technical field [0001] The invention belongs to the technical field of interference fit disassembly, and more specifically relates to an expandable disassembly device and method for interference fit special-shaped housings. Background technique [0002] In the engineering practice of disassembling the special-shaped shells with interference fit, on the one hand, the two sections of special-shaped shells with interference fit must be separated non-destructively, otherwise it will cause damage to the special-shaped shells; The huge impact force at the moment of separation should be fully considered to avoid damage to components or instruments in the housing. Therefore, the disassembly of the special-shaped housing has extremely high requirements on the uniformity of the disassembly force around the disassembly housing. [0003] In addition, during the disassembly process, the disassembly device needs to fix the special-shaped shell first. Due to the diversity of the diameters...
