Description

Electromagnet winding process and device Technical Field The invention relates to the technical field of electromagnets, in particular to an electromagnet winding process method and device. Background The electromagnet is used in an aircraft electromagnetic valve and comprises a push rod, a framework, a stop block, an armature and a coil, wherein the coil is formed by winding an enameled wire in the framework, the push rod is made of a non-magnetic material (such as copper), the framework, the stop block and the armature are generally made of a soft magnetic material (electrical pure iron DT 4A), the coercive force is small, the magnetization is easy, the stop block is fixedly arranged, and the armature can flexibly move in an inner cavity of the framework under the action of a magnetic field. The stop block and the armature can be magnetized rapidly under the action of a magnetic field generated by coil current, and the stop block and the armature are magnetized into a magnetic field unit, wherein the magnetic pole sequence is N stop block S and N armature S according to the structural sequence. The magnetic field characteristics are opposite to each other, the armature is attracted to the stop block, and the ejector rod is pushed to open the front valve. The current direction is opposite, the magnetic pole sequence is opposite, namely an S stop block N and an S armature N, although the magnetic pole directions are opposite, are opposite and absorb, and the armature is absorbed to the stop block to push the ejector rod so as to open the front end valve. It appears that the electromagnetic thrust direction is unchanged. Therefore, the winding direction (left-handed or right-handed) of the electromagnet is not affected. Under the condition that the electromagnet coil is powered off, the current magnetic field disappears, the magnetic field of the soft magnetic material (with smaller coercive force and small remanence) almost disappears, the electromagnetic force between the stop block and the armature is also disappeared, and the initial position of the armature is restored under the action of the front valve spring. In the long-term use and disassembly repair process of the electromagnet, the faults of corrosion, uninstallation, damaged enameled wires, unqualified electromagnet performance and the like can not be used continuously, so that the electromagnet is scrapped. Therefore, the device and the method for repairing the electromagnet are designed, and have important significance in electromagnet maintenance operation. However, the original electromagnet is decomposed in real object, so that the enameled wires and the lead-out wire connectors are embedded into the coils, the winding turns of each layer of the coils are different, the layers are not distinct and regular, the enameled wires at the two ends are more disordered and have fewer turns, the middle turns are more and are more regularly arranged from the appearance, and the coils at the two ends of each layer are further decomposed, so that the winding turns are not reduced in an arithmetic progression, but are staggered, and the manual winding characteristic is obviously shown. Therefore, the problems of wire jumper and sparseness caused by accumulated errors of wire diameters of the enameled wires, controlling the tension of the enameled wires, expressing the servo relationship between the wire feeding function and the winding of the skeleton driven by the main shaft, and the like exist. Disclosure of Invention In order to solve the technical problems, the invention provides an electromagnet winding process method and device. The original electromagnet framework is utilized to wind the coil again to restore the original design state and continue to be used, so that the maintenance quality and the spare part utilization rate of the aircraft electromagnet are improved, and the method has important significance in electromagnet maintenance operation. The technical problems to be solved by the invention are realized by adopting the following technical scheme: an electromagnet winding device comprises a frame and a tensioner frame; The top of the frame is provided with a large bottom plate, the large bottom plate is correspondingly provided with a tail top mechanism, a main shaft box, a winding motor and a wire arranging mechanism, the tail top mechanism is arranged opposite to the main shaft box, the winding motor is connected with the main shaft box, the wire arranging mechanism is slidably provided with a wire feeding mechanism, the wire feeding mechanism is fixedly provided with a winding length detecting mechanism, and the wire arranging mechanism is positioned at the side edge position between the tail top mechanism and the main shaft box; The upper end part of the tensioner frame is fixedly provided with a servo motor active wire feeding tensioner, and the bottom of the tensioner frame is provided with an enameled wire; and after the enamelled
