AI Technical Summary

Problems solved by technology

The conventional disassembly operation is to hang the casing 12 with a crane, and smash the outer wall of the casing 11 obliquely with a rubber hammer to realize the decomposition of the casing 12. This decomposition mode is easy to cause damage to the casing 11.

Embodiment Construction

[0035]Embodiments or embodiments of a variety of different implementation techniques disclosed will be disclosed. In order to simplify the disclosure, specific examples of each component and arrangement are described below. Of course, these are only examples, which are not limited to the scope of the invention. For example, the first feature described in the specification is formed above or above or above, and may include the first and second features to be formed by direct contact, or may be formed between the first and second features. Additional features of the additional feature thus can be contacted directly between the first and second features. Additionally, these disclosures may repeat the reference numerals and / or letters in different examples. This repetition is for the sake of brief and clear, it does not represent the relationship between the embodiments and / or structures to be discussed. Further, when the first element is described in connection with the second elem...

Abstract

The invention provides casing disassembling tools and a casing disassembling method, which are used for disassembling casings and preventing the casings from being damaged by hammering in the process of disassembling the casings. Threads with different rotating directions are arranged at the two ends of a lead screw of each disassembling tool respectively, each lead screw is further provided with a torsion applying part, and the torsion applying part of each disassembling tool is arranged to be not shielded by a supporting frame of each disassembling tool; each upper top base is provided with upper guide holes matched with guide shafts of the corresponding disassembling tool, and is provided with an upper threaded hole matched with the thread at the upper end of the lead screw of the corresponding disassembling tool, and upper positioning pins are arranged on the upper top surface of each upper top base and used for being matched with holes in a rear mounting edge of the second casing; each lower top base is provided with lower guide holes matched with the guide shafts of the corresponding disassembling tool, and is provided with a lower threaded hole matched with the thread at the lower end of the lead screw of the corresponding disassembling tool, the lower top surface of each lower top base is provided with lower positioning pins matched with holes in a rear mounting edge of the disassembling tool first casing, and each lower top base is provided with bosses; and the height of the disassembling tool bosses is larger than the thickness of the front mounting edge of the second casing, and the bosses correspond to notch grooves in the front mounting edge of the second casing.

Description

Technical field[0001]The present invention relates to a disassembly tool, in particular a decomposition tool between two partial macies connected by a stop.Background technique[0002]The machine is the main component of the engine stator, and partial cartridge is the main support force frame of the engine. In order to ensure the coaxial degree of the mash assembly, the casing 11 and the cartridge 12 are generally passed through the short-length stop 13 Connection, such asfigure 1 Indicated. Lessing ratio is an important indicator of the engine, the machine needs to minimize the thickness of the casing to mitigate the weight of the cassette under the premise of ensuring sufficient stiffness.figure 1 ,figure 2 The mating degree of the two mounting edges 111, 121 shown is about 0.1-0.15mm, and the mounting edge 121 thickness of the casing 2 is less than 5mm, such as setting a top wire hole, removing the edge of the mounting hole, effective If the thickness is less than 3mm, the decompos...
