Electric flaring device and method

Abstract

The invention provides an electric flaring device and method. Uniform force application is achieved, the mounting part of a part needing flaring is flatly attached to the part, the mounting efficiency is improved, and mechanical damage to the part is reduced. The electric flaring device comprises a tip, a C-shaped body, a screw and a constant-torque motor; the screw comprises a ball head rod and a threaded rod, the ball head rod and the threaded rod are connected in a sleeved mode through a key, the middle of the ball head rod is rotationally connected with the C-shaped body through threads, and the tail of the threaded rod is fixedly connected with the constant-torque motor through threads; the tail part of the tip is fixedly connected with the head part of the ball head rod through threads; the outer side of one end of the C-shaped main body is connected with a mounting device through fixing screws, and the inner side of the other end is used for supporting the part; the constant-torque motor comprises a motor main shaft and a motor main body, the motor main body is fixedly arranged between the C-shaped main body and the mounting device through fixing screws; and the motor body is sequentially connected with a control box and a plug through control power lines.

Description

technical field [0001] The invention belongs to the technical field of flaring tools, and relates to an electric flaring device and method. Background technique [0002] At present, due to the advantages of high reliability, convenient replacement, low replacement cost, and low requirements for the working environment, the flared parts in aero-engine components are more and more applied to various connection structures. [0003] However, when installing the parts that need to be flared, it is necessary to use a specific and suitable device, and generally by manual operation, the edge of the mounting hole of the part that needs to be flared is deformed to achieve a locked state, and the installation position of the part that needs to be flared Flatten with the part of the parts to prevent the installation of other parts from being affected, so as to meet the requirements of subsequent engine assembly of other parts. Regarding the installation and locking of parts that need t...

Problems solved by technology

Regarding the installation and locking of parts that need to be flared, various mechanical processing journals, etc. have related articles. For example, the application number is CN2018114978 29.1, and the publication number is CN109530572A. It is used for the closing of parts and cannot be used as a flaring device; there are also a small number of designs for specific part structures, such as the application number CN201810541905.8 and the publication number CN108789260A mentioned "A kind of nut for installing the bracket The hole reamer and method of ", has great limitations, and cannot be applied to the structure of parts that generally need to be reamed

[0004] The existing installation method of the parts that need to be flared is operated by manually holding the locking fixture. The labor intensity of the workers is high, the installation efficiency is low, and mistakes are prone to occur during the manual operation process, resulting in mechanical damage to the parts, or due to manual force. Unevenness causes the installation part to not be completely flattened, which affects the requirements for subsequent engine assembly of other parts
