Abstract
The invention provides a process for welding a stator punching sheet of a high-efficiency permanent magnet direct-current synchronous motor in an electric vehicle, which comprises the following processes of: sleeving the motor stator punching sheet in a punching sheet compressing tool; arranging the punching sheet compressing tool and the motor stator punching sheet on a laser welding tool; and arranging a welding head of a laser welder above a center line of the laser welding tool to perform laser welding on the peripheral wall of the motor stator punching sheet. In the motor stator punching sheet manufactured by the welding process, a yoke part of the stator punching sheet is not damaged basically, namely the yoke magnetic flux of a motor stator cannot be increased, so the loss of the motor is reduced, the efficiency of the motor is improved, and the weight of the motor is relieved. Simultaneously, due to the simple laser welding process, the damage degree to the stator is extremely low, the welding is quick, the surface of the stator punching sheet is smooth and the welding firmness is high. Therefore, the welding process is a new process for welding the stator punching sheet of the high-efficiency motor.
Description
Technical field

The specific embodiment
The embodiment that provides below in conjunction with accompanying drawing is described in further detail the welding procedure of electric motor car DC synchronous motor stator of the present invention punching.
Referring to Fig. 1,2,3,4, the welding procedure of electric motor car efficient permanent magnet direct current synchronous motor stator punching, its innovative point is: comprise following operation successively:
A, motor stator punching 1 is enclosed within a punching compresses being with on the externally threaded sleeve pipe 2-3 that the left clamping plate 2-1 of frock 2 is provided with, to have then internal thread, profile is polygonal right clamping plate 2-2 and is connected with the casing threads of left clamping plate 2-1, make motor stator punching 1 be held and be pressed between the left and right clamping plate, and the thrust of adjusting clamping by connecting thread makes the size of motor stator punching 1 reach designing requirement, and profile is the integral multiple of the weld seam quantity of required laser weld on polygonal its polygonal limit number of right clamping plate 2-2 and the motor stator punching 1;
B, punching is compressed frock 2 be placed on the laser weld frock 3 together with motor stator punching 1, it is rotating to be about to the endoporus with externally threaded sleeve pipe 2-3 that left clamping plate 2-1 that punching compresses frock 2 is provided with
Be sleeved on the back shaft 3-2 that laser weld frock 3 gripper shoe 3-1 are provided with, the locating piece 3-3 that then laser weld frock 3 is had locating platform 3-3-1 is supported on profile and is under the side plane of polygonal right clamping plate 2-2;
C, be placed on the back shaft 3-2 center line top of laser weld frock 3, finish the laser weld of carrying out article one weld seam at the periphery wall place of motor stator punching 1 with the soldering tip 4 of laser-beam welding machine;
