Abstract
The utility model discloses a motor rotor coil end end-to-end joint fixing device provided with an H-shaped connecting sleeve, wherein copper-phosphorus welding solder with the U-shaped section is placed in each of an upper groove and a lower groove of the H-shaped connecting sleeve; and the size of the copper-phosphorus welding solder is matched with the upper groove and the lower groove, the height thereof is slightly higher than that of the upper groove and the lower groove of the H-shaped connecting sleeve, and the shape thereof is similar to that of the motor rotor coil end. The fixing device leads the copper-phosphorus welding solder compression molded to be embedded between the motor rotor coil end end-to-end joint and the connecting sleeve, and conducts heating through high frequency induction until the solder is fully melt and fixed into a whole. In the motor operation situation, the current flowing through the motor rotor coil end end-to-end joint does not heat the part; and the fixing device can ensure the welding quality and improve the performance and reliability of a motor.
Description
Technical field
The utility model relates to an a kind of motor-spin-coil end and a fixture.
Background technology
The also head of the rotor structure rotor rotor coil end of motor rule formula fixedly is one critical process, the connection of motor-spin-coil end and head is all fixed by adapter sleeve, between rotor coil end electromagnetic wire and the adapter sleeve reliable contact-making surface to be arranged, and head place area is reasonable, could guarantee to flow through under electric motor starting, ruuning situation and the electric current at head place can not make this place heating, a rotor coil end also quality directly has influence on motor properties and reliability.An existing motor-spin-coil end and a fixture are to adopt the annular and the headgear of rectangular configuration, with motor-spin-coil end and head place parcel, also inlay and the wedge of coil electromagnetism line in the head place at upper coil and inner coil end with material, be somebody's turn to do and the head place in order to wedging, when adopting the high-frequency induction heating welding, the annular of rectangular configuration and headgear heating formerly reach (kelvin effect), and the exposed electromagnetic wire of end winding and head place is not heated to welding temperature, weld very difficult, heating time long this weld insulating material scaling loss that causes, and the annular and the headgear cost higher.Problem of faulty soldering is very serious when adopting oxygen-acetylene soldering, directly has influence on motor performance and reliability.
The utility model content
The utility model purpose is to provide an a kind of motor-spin-coil end and an adapter sleeve.Make an electric current that flows through motor-spin-coil end and head place under the motor ruuning situation can not make this place's heating with realization, and a reduction and an adapter sleeve cost.
The technical solution of the utility model is: be provided with a H shape adapter sleeve; The copper phosphorus welding filler metal that respectively to place a section in two grooves up and down of H shape adapter sleeve be U-shaped, the size of described copper phosphorus welding filler metal adapts with two grooves up and down; Its height is a little more than the height of the upper and lower groove of H shape adapter sleeve, and the shape of its shape and motor-spin-coil end is close.
During use, the welding filler metal of compression molding is embedded between a motor-spin-coil end and the adapter sleeve, heating by high-frequency induction, reach up to heating and solder is melted fully be fixed into one. an electric current that flows through motor-spin-coil end and head place under the motor ruuning situation can not make this place generate heat.
The size of described copper phosphorus welding filler metal is between 0.14-0.2mm.
The utility model effect: the welding filler metal of compression molding is embedded between a motor-spin-coil end and the adapter sleeve, heating by high-frequency induction, reach up to heating and solder is melted fully be fixed into one. an electric current that flows through motor-spin-coil end and head place under the motor ruuning situation can not make this place generate heat.Guarantee welding quality, improved motor properties and reliability.

Embodiment
The utility model is described in further detail below in conjunction with accompanying drawing.
Embodiment: with reference to accompanying drawing:
Be provided with a H shape adapter sleeve 1; Respectively placing one on H shape adapter sleeve in the low groove 2 is the copper phosphorus welding filler metal 3 of U-shaped with its section that adapts of H groove up and down, and what the copper phosphorus welding filler metal of present embodiment was selected for use is the thick copper phosphorus scolder of 0.15mm.The size of copper phosphorus welding filler metal adapts with two grooves up and down; Its height is a little more than the height of the upper and lower groove of H shape adapter sleeve, and the shape of its shape and motor-spin-coil end is close.
The naked electromagnetic wire 5 of naked electromagnetic wire 4 in lower floor rotor coil end and rotor coil end, upper strata is embedded H shape adapter sleeve 1 respectively to be placed with up and down in the upper and lower groove of U-shaped welding filler metal 3 in advance.During work, adopt high-frequency induction to heat, reach up to heating U-shaped welding filler metal 3 melt fully, treat that solder solidifies after, rotary rotor is to the adjacent adapter sleeve 1 of next adapter sleeve 1(), this step of photograph is finished the welding of adapter sleeve 1, finishes up to whole welding.Be welded to connect cover at 1 o'clock, and burnt out for preventing near the rotor coil insulating material this adapter sleeve 1, can water or compressed gas cooling, when use water cooling, welding is finished this rotor and must be advanced baker and heat water is evaporated.Adopt the adapter sleeve of this planform and the advantage that welding filler metal has suitable high-frequency induction heating, mother metal and rotor coil end and adapter sleeve are together heated, heating time is shorter, between U-shaped welding filler metal dislocation adapter sleeve 1 and rotor coil end, when adding thermal weld more in addition, only need to replenish a spot of solder of the same type.
Claims (2)
1. a motor-spin-coil end and a fixture is characterized in that, are provided with a H shape adapter sleeve; The copper phosphorus welding filler metal that respectively to place a section in two grooves up and down of H shape adapter sleeve be U-shaped, the size of described copper phosphorus welding filler metal adapts with two grooves up and down; Its height is a little more than the height of the upper and lower groove of H shape adapter sleeve, and the shape of its shape and motor-spin-coil end is close.
2. a motor-spin-coil according to claim 1 end and a fixture is characterized in that the size of described copper phosphorus welding filler metal is between the 0.14-0.2mm.
