Abstract

The utility model provides an intermediate frequency generating set used for welding. A main body of the intermediate frequency generating set adopts a structure of double-rotor and double-stator, wherein, two stator assemblies are arranged inside a cylindrical shell, an output line of the stator is educed from the middle of the cylindrical shell and takes a left end closure and a right end closure as the support, two rotor assemblies are arranged on a rotor spindle and are supported inside the stator assemblies by a bearing arranged at the two ends of the rotor spindle. A carbon brush component and a brush holder component are arranged on the end part of the rotor spindle. The cylindrical shell is internally provided with a centrifugal fan, the top part of the right end closure is opened with a hole, the interstice of the internal and external circles inside the stator assemblies and a pylome at the middle of the rotor assembly as well as an opening on the circle of the left end closure together form a heat dissipation air channel to guarantee the good heat dissipation of an electric motor. The utility model takes two completely independent rotational magnetic fields generated by power at the structure of coaxial double-rotor and double-stator and two completely independent induced currents generated by cutting magnetic lines of force with two independent stator coils as a power supply to provide power for two welding rod holders, thereby solving the problem of robbing electricity between two welding rod holders.

Description

Welding intermediate frequency generator group

Technical field

The utility model relates to a kind of source of welding current equipment, relates to a kind of generator that is used for pipeline welding in particular.

Background technology

At present, the leading equipment that is used for the power-supply device of pipeline welding be by diesel engine directly drive two the arc generator group.Main employing is the power frequency generator for electricity generation in the world, structure is taked on the stator of same generator the mode around two bond pads windings and one group of power frequency power electricity winding, and this mode is difficult to solve effectively the interference problem of robbing between two electrode holders between electricity and two electrode holders and the power frequency power electricity.

Summary of the invention

The utility model is the above deficiency that overcomes prior art, a kind of welding intermediate frequency generator group is provided, fundamentally solved the two the problem of robbing electricity between two electrode holders of integrated welding equipment of pipeline welding, this generator also has special heat dissipation wind channel to guarantee that the generator heat radiation is good.

For solving the technical problem of above-mentioned existence, the utility model has adopted following technical proposals: this intermediate frequency generator agent structure adopts birotor, double-stator structure, also has special heat dissipation wind channel simultaneously.

Described birotor, double-stator structure are constructed as follows: two field frame assemblies are installed in the cylindrical shell; The stator output line is drawn in the middle of cylindrical shell, supports with left end cap and right end cap; Two rotor assemblies are installed on the armature spindle, and the bearings by the armature spindle two ends is among field frame assembly.Carbon brush component, brush handle assembly are installed in the end of armature spindle.The power of diesel engine reaches the intermediate frequency generator armature spindle after the speed changer conversion, two rotor assemblies rotate synchronously, exciting current arrives two rotor coils through carbon brush component, collector ring, thereby produce two fully independently rotating magnetic fields, two nail coil cutting magnetic lines and produce independently induced current of two-way safety incessantly independently are to supply with two electrode holders of welding machine part.

Centrifugal fan is installed in the cylindrical shell, and heat dissipation wind channel, described heat dissipation wind channel are arranged is the perforate by the right end cap top in design on the whole generating unit, the space at field frame assembly inside and outside circle place, and perforate forms jointly on the through hole at rotor assembly middle part and the left end cap circumference.When armature spindle rotated, under the effect of centrifugal fan, cold wind entered from right end cap, flowed along circle cylindrical and rotor assembly middle part through hole in the field frame assembly, absorbed the heat of rotor, stator, discharged from left end cap, thereby guaranteed that the generator heat radiation is good.

The utility model will be by producing two fully independently rotating magnetic fields through the power of speed changer conversion under the structure of coaxial birotor, two stators, two stator coil cutting magnetic lines and produce fully independently induced current of two-way incessantly independently, formed two independently power supply supplying with two electrode holders, thereby solve the problem of robbing electricity between two electrode holders.The generator good performance of heat dissipation has been guaranteed in special in addition air channel design.
