Embodiment
[0030] This example is an improvement to the existing technology: the commutator structure of the traditional motor is as image 3 As shown, mica sheets 23 are used for insulation between the commutator segment and the commutator segments and at both ends. The two ends of the commutator are connected with a sheath 24, and a rubber gasket 25 is provided between the sheath and the mica sheets at both ends of the commutator. The commutator structure of the traditional motor has a troublesome manufacturing process and large volume, which has been gradually eliminated. Currently commonly used commutators such as Figure 4 As shown, mica sheet 23 is still used for insulation between the commutator segment and the commutator segment, and the bakelite powder is used to fill 27 between the commutator segment 22 and the sleeve 26 and both ends of the commutator. The existing commutator manufacturing process It is simple, small in size and reliable in performance. It has been widely used i...

The invention discloses a method and tool for welding flat type copper wire windings and commutators of a high-power motor. The method for welding the flat type copper wire windings and the commutators of the high-power motor comprises the steps that flat type copper wires at the two ends of each winding are welded into wire insertion grooves in the corresponding commutators through argon arc welding; axial movement of a rotor is limited through a rotor support during welding, and the rotor is allowed to rotate; an argon arc welding gun is fixed through a welding gun holder, so that it is guaranteed that the distances between a tungsten electrode on the argon arc welding gun and welding spots are kept within a permissible range all the time so as to improve the welding quality; and in the welding process, insulation between pieces of the commutators is prevented from being damaged through a high welding temperature in a water flushing cooling way. The difficulty in a commutator electrowelding technique is well overcome through the simple method and tool. By the adoption of the method and tool, the welding spots of the welded commutators are even and uniform, color changes are avoided, the surfaces of the welding spots are smooth, the defects such as bubbles are avoided, and adhesion between the welding spots is avoided. The colors of the surfaces of the commutators are normal.
Description
technical field [0001] The invention relates to a high-power motor flat copper wire winding and a commutator argon arc welding method and used tooling, belonging to the technical field of motor manufacturing. Background technique [0002] The commutator structure of the traditional motor uses mica sheets for insulation between the commutator and the commutator, and the two ends of the commutator are connected to the sheath, and rubber gaskets are installed between the sheath and the mica sheets at both ends of the commutator . The manufacturing process of the commutator structure of the traditional motor is cumbersome and bulky, and has been gradually eliminated. At present, the commonly used commutator structure still uses mica sheets to insulate between the commutator segments and the commutator segments, and bakelite powder is used to fill the gap between the commutator segment and the bushing and at both ends. Small, reliable performance, has been widely used in China....
