Flanging opening device for maintaining civil aviation stepping motor

Abstract

The invention discloses a flanging opening device for maintaining a civil aviation stepping motor. The flanging opening device comprises a punch shank with the lower end connected with a bottle-shaped flanging opening barrel which has a small upper end and a large lower end, the step at the bottle beck part of the flanging opening barrel is downwards in clearance fit with a suspension type limit sleeve, a circle of arc-shaped punch plates capable of elastically expanding outwards are uniformly distributed on the periphery of the lower part of the flanging opening barrel, a wedge-shaped expansion punch pin with a bottom surface forming an angle of 45 degrees with the lower side of the outside and with outer side surfaces tilting inwards at 10-15 degrees is arranged at the lower end of each arc-shaped punch plate, a window is formed in the limit sleeve corresponding to the punch pin, a motor fixing base is composed of two semi-circular motor clamping plates upwards installed around a central boss on a substrate, a fastening bolt is installed between the two motor clamping plates, motor fixing slots are formed in the tops between the motor clamping plates, and a semicircular clamping platform is arranged on the inner wall of each motor fixing slot. The flanging opening device has the advantages of being convenient to operate, safe, reliable and capable of effectively maintaining the civil aviation stepping motor and avoiding waste.

Description

Technical field: [0001] The invention is a side-opening device for maintenance of the stepping motor, which is suitable for opening the end cover when the interior of the civil aviation stepping motor is overhauled. Background technique: [0002] At present, the stepper motor installed on civil aviation aircraft is a multifunctional special stepper motor, and its main components are all located in the casing. Pressing at 45° to the outside of the central axis, the general tool cannot meet the positioning guide to open the flange. Once the general tool is used to open it, it is easy to cause damage to the casing and cannot guarantee the safety of the components. There is no special tool for opening. The stepper motor end cap implements. After the motor fails, it is directly scrapped, and a new stepping motor is reinstalled, causing unnecessary waste. Invention content: [0003] The purpose of the present invention is to provide a civil aviation stepping motor maintenance ...
