[0002] For the gear shifting process of automatic gearbox of automobile, the switching of oil circuit inside the gearbox and oil pressure adjustment are adjusted by adjusting the opening and closing and opening degree of valve body, and then the gear position is adjusted, different valve bodies control different clutches or brakes and play a role in different gear positions. Because the oil pressure inside the gearbox is high, the slight opening degree fluctuation of valve body will affect the smoothness of gearbox shifting, causing shifting impact, and then the clutch plate and brake band inside the gearbox will be worn out, causing more serious faults. Therefore, the valve body has high requirements in the design and development and production process, so the valve body needs to be disassembled in the design stage and the later production line mass production stage to analyze the performance of the valve body. However, there is no equipment specially used for disassembling this kind of micro valve body. Mostly, the disassembly is carried out by violent means, which will seriously damage the state of the micro valve body and cause secondary damage, interfere with the analysis of the real state of the micro valve body, and the disassembly efficiency is low.

[0003] The invention patent with the authorized announcement number CN 110052996 B discloses a dismounting device for derailment valve, which comprises a base, a rotating dismounting assembly, a support, a first wrench and a second wrench. The rotating dismounting assembly is arranged on the base and connected with a sleeve for fixing the valve body of the derailment valve, the axis of the sleeve is collinear with the axis of the rotating dismounting assembly. The support is arranged on the base and located on the two sides of the sleeve in the radial direction, used for supporting the top beam of the derailment valve. The first wrench is detachably connected with the sleeve and used for fastening the action rod locking nut of the derailment valve. The second wrench is overlapped on the support and used for fastening the action rod locking nut of the derailment valve and / or the top beam locking nut of the derailment valve. The dismounting device for derailment valve rotates the valve body by the sleeve and dismounts the derailment valve by the mode that the action rod locking nut of the derailment valve and / or the top beam locking nut of the derailment valve does not rotate. Although the device can also be used for mechanically dismounting the valve body, it is only suitable for the derailment valve of large structure of railway train, and cannot be directly applied to the dismounting of micro valve body for automobile.
