    Apparatus for soldering the wires of the coil on the armature of an electric machine to the commutator thereof. The apparatus has a device for clamping, shifting and fixing the armature, a monophase magnet-hydrodynamic pump with a charger and a pan with molten solder. The magnetic core of the pump has the shape of a hollow cylinder and is externally chamfered at its upper end. The armature to be soldered is disposed vertically with the lower portion of its commutator telescoped within the upper end of the core. Around the core within the pan there is an annular charger disposed coaxially of the core, the charger having its lower end above the bottom of the pan and its upper end on the level of the upper chamfered end of the core so as to form between the upper end of the charger and the upper chamfered end of the core an annular frusto-conical channel with a discharge end directed toward the upper portion of the commutator and the parts of the wires adjacent thereto to solder the wires to the commutator.

    专利说明:

    The invention relates to a device for soldering wires of a winding core to a collector of electric machines, comprising a device for creating a stream of molten iripo, connected with a device for mounting onto bearings and fixing rotors in the Space and a device for turning rotors about their axis. The collectors are soldered by immersing the collector feathers in a stream of molten solder, while at the same time, the collectors are given a rotational movement around their axis.
    The disadvantages indicated. Installations are the design complexity and complexity of the system for melting, heating and adjusting the temperature of the solder, a greater length of the liquid metal path and increased consumption of electrical energy.
    A known device for soldering a winding to an electric masking collector, comprising a device for creating a stream of molten solder, which is a single-phase magnetohydrodynamic pump consisting of a winding and a cylindrical magnetic conductor, connected to a bath and a two-hose supercharger; near its axis and a device for gripping, moving, and fixing the core with the collector relative to the supercharger and the hoses.
    Known installation is intended mainly for soldering the winding to the manifold end type. Working with it requires the rotational movement of the rotor of the electric maschine, a longer working cycle and is associated with a greater consumption (consumption) of electrical energy.
    The purpose of the invention is to create a unit for soldering a winding to the collector of electrical machines, which would have a simplified design in combination with high productivity and reduced energy costs.
    The goal is achieved by the fact that in a soldering unit for a winding to a collector of electrical masks containing a device for Capturing, moving and fixing the core with a collector, a single-phase magnetohydrodynamic pump with a supercharger and a bath with molten solder, the magnetic circuit of a single-phase magnetohydrodynamic pump has the shape of a hollow, glued the upper end of the cylinder, around which the compressor is concentrically located, the lower end of which is above the bottom of the bath, and the upper one is parallel to the velocity upper This is a part of the magnetic circuit, and an annular groove is formed between the upper part of the supercharger and the upper skanchennoy part of the magnetic circuit, inclined at a certain angle relative to the He, .j) CH collector.
    In the hole of the magnetic circuit is an adjustable reference centering element.
    FIG. 1 shows the installation in the working position, the cut; in fig. 2 - the same, with an adjustable support centering element located in the bore of the magnesium conductor.
    Under the bath 1 (Fig. 1) with molten solder 2, a single-phase magnetohydrodynamic pump 3 is located, the magnetic circuit of which has the shape of a hollow cylinder 5 in its upper end of the cylinder. A supercharger 5 is concentrically located around the magnetic core, the lower end of which is above the bottom of the bath 1, and the upper parallel to the high-speed upper part of the magnetic core 4. Between the upper part of the supercharger 5 and the upper velocity-shaped part of the magnetic core 4, an annular groove 6 is formed, which is inclined at a certain angle relative to the axis of the magnetic core 4.
    3 In the installation variant (FIG. 2), in the hole of the magnetic circuit 4, a fixedly adjustable centering element 10 is arranged.
    The installation operates as follows.
    0 Bath 1 is charged with liquid solder 2 at O1 at a certain temperature, which is maintained by the heat generated by the liquid metal as a result of the action of a single-phase magnetohydrodynamic pump 3 and blowers from electrical resistances placed around the cylindrical surface of bath 1 (not shown). With the help of a device for gripping, moving and fixing (not shown), the measles with the collector 7, on which the technological threshold 8 has previously been left (Fig. 1), are set vertically in the opening of the magnetic circuit 4 to occupy the working position. The technological threshold 8 tightly presses the upper part of the magnetic circuit 4. A single-phase magnetohydrodynamic pump 3 is turned on. Pressure is created in the annular groove 6, under the action of which the melted solder 2 flows out, pours all the collector's feathers 7 at the same time, heats and penetrates the channels of the collector plates and coils the windings the collector 7, and the solder will return to the bath 1. At the end of the soldering process, the single-phase magnetohydrodynamic pump 3 is switched off before the installation of the next collector, than chivaets rabo5 Chii cycle. Due to the technological threshold 8, the collector 7 is sealed to the upper opening of the magnetic circuit 4, and the penetration is molten
