Description
One, technical field
The utility model belongs to the intermediate frequency welding technology field.
Two, background technology
Rotor is generally mouse cage type structure, and many slivers that vertically are arranged in parallel on the rotor need to be one with the copper end ring weldering of rotor termination.Usually rotor adopts the welding of gas brazing technology, and this technology investment is little, and is simple.But owing to the submersible motor rotor is carefully grown, rotor thermal effectiveness that sweating heat has been interfered heavy damage causes the rigidity of armature spindle and comprehensive mechanical intensity to reduce greatly, has had a strong impact on the complete machine quality.
Three, summary of the invention
The purpose of this utility model provides a kind of rotor medium frequency inductive brazing machine, to improve the rigidity and the mechanical strength of armature spindle.
The utility model is achieved in that rotor medium frequency inductive brazing machine, intrinsic 4 root posts 4 between upper head plate 13 and base 1, oil cylinder 10 is installed on upper head plate 13, the below of oil cylinder 10 is equipped with induction hardening transformer 6, and the guide wheel of installing in the both sides of induction hardening transformer 67 is movably arranged on two pillars simultaneously; Side at induction hardening transformer 6 also is equipped with induction coil 12; Work-sheet pressing oil cylinder 11 is installed on upper head plate 13, and it is top 9 that the lower end of oil cylinder 11 is fixed with, and is provided with toply down 3 with oil cylinder 11 corresponding positions on base 1, and fixing motor 2 connects down top 3 by transmission device on the base 1.On the support of induction coil 12, be fixed with loading hopper 8.
Compare with background technology, the beneficial effects of the utility model are: utilize the kelvin effect of heating in medium frequency, make weld heating only limit to welding position, rotor top layer, armature spindle does not generate heat or few heating, can not make rotor produce heating annealing phenomenon.Adopt rotor medium frequency inductive brazing machine to improve the quality of product, greatly reduce cost, high efficiency.
Four, description of drawings
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the end view of Fig. 1.
Five, specific embodiment
The structure of workpiece is that the copper end ring at motor rotor core and two ends is fitted together by motor shaft, and many slivers pass the copper end ring and the core stamping at two ends successively.Welding procedure is to be one with sliver and the soldering of copper end ring, forms mouse cage.During welding, earlier workpiece 5 settings are fixed on down between top 3 and upward top 9, then mobile induction hardening transformer 6 makes induction coil 12 be enclosed within copper end ring periphery exactly.The guide wheel 7 that install the both sides of induction hardening transformer 6 rolls along two pillars surface and leads, and induction hardening transformer 6 is moved up and down.Then, starter motor 2 rotates workpiece 5, restarts intermediate frequency power supply, make workpiece 5 produce the vortex flow heating by induction coil 12, add welding powder in due course, welding powder adds to copper end ring surface by loading hopper 8, along with heating, melt, realized the soldering processes process of copper end ring and sliver.
Induction hardening transformer oil cylinder 10, Work-sheet pressing oil cylinder 11 are communicated with Hydraulic Station by pipeline; Intermediate frequency power supply is connected with induction hardening transformer 6 by private cable; Cooling water tank connects intermediate frequency power supply, induction hardening transformer 6, induction coil 12 by cooling water pipe, and by tank pressure, boiler water circulation realizes the purpose that total system cools.
