Edge opening device for maintenance of stepping motor

Abstract

The invention discloses an edge opening device for maintenance of a stepping motor. The edge opening device comprises a first fixing frame, a second fixing frame, a sliding block, an electric hydraulic rod and an edge opening mechanism. a crank is adopted to control a clamping plate to move, the reinforcing tightness is easy to control while labor is saved, a rubber pad is further installed on the surface of the clamping plate, the stepping motor shell can be protected against scraping damage while skid resistance is achieved, after the upper portion and the lower portion of a stepping motor shell are fixed, the stepping motor shell is slowly separated through a hydraulic electric rod, operation is easy, and the edge opening efficiency is high. According to the edge opening device, the clamping plate or a hammer block can be replaced according to different types of stepping motors, the hammer block is controlled and pulled through the crank, so that a fixing block slowly deviates to open a machine shell, the control force and the moving distance are easy to grasp, and the shell of the stepping motor cannot be damaged; a special maintenance tool box and a lighting device are arranged on the device, needed edge opening tools can be placed in the tool box, the lighting device is matched with a strong magnet and a gooseneck pipe, and the lighting requirement of an operator is met.

Description

technical field [0001] The invention relates to the technical field of stepping motor maintenance, in particular to a side opening device for stepping motor maintenance. Background technique [0002] Stepping motor is also called pulse motor. Based on the most basic principle of electromagnet, it is an electromagnet that can rotate freely. Its action principle is to rely on the change of air gap permeance to generate electromagnetic torque. , the rotor rotates an angle or advances one step, its output angular displacement or linear displacement is proportional to the number of input pulses, the speed is proportional to the pulse frequency, and the angular displacement of the stepping motor is strictly proportional to the number of input pulses. And it is synchronized with the pulse in time, so as long as the number, frequency and phase sequence of the motor winding are controlled, the required rotation angle, speed and direction can be obtained. When a stepper motor fails, i...

Problems solved by technology

However, this device uses the impact method to offset the fixed block on the special type stepping motor to achieve the effect of opening the edge. Since the impact is artificially controlled, it is very easy to damage the shell and internal components of the stepping motor, and it is not easy to remove the stepping motor. Maintenance; the base is fixed by bolts, and the bolts need to be reinforced with external tools. Frequent use will wear out, and the bolts may be damaged and slip and cannot be opened; in addition, there are many types of existing stepper motors, and many devices The connection between the shell and the inside is tight, and the shape and size are different. However, this device is only suitable for special stepping motors in civil aviation, and it is difficult to meet the open side requirements of most stepping motors.
