Technical scheme of the present invention is achieved in the following ways: a kind of method for laser welding of automobile gearbox planet carrier, comprises the following steps:
A, firm banking is packed on the scroll chuck of driving mechanism and clamp;
B, planet carrier three-jaw support is arranged on firm banking through three alignment pins;
C, three isometry blocks are arranged on respectively on three alignment pins;
D, be installed together through three alignment pins and planet carrier three-jaw support corresponding three locating holes of hub in planet carrier;
E, first location briquetting is arranged in planet carrier on hub, then opening briquetting is arranged on the briquetting of location;
F, tighten locking nut, hub in planet carrier three-jaw support and planet carrier is fixed;
G, boss inductance loop is arranged on planet carrier firm banking, rotation regulates the position of boss inductance loop to make three boss original positions consistent with three sections of circular arc weld seam original positions of planet carrier respectively, tightens boss inductance loop locking nut;
The lug boss position of described boss inductance loop is 120 ° evenly divides on inductance loop, can be adjusted into many boss different angles and be distributed on inductance loop, realizes the welding of the circular arc weld seam that multistage is not isometric, multistage is isometric.
H, startup driving mechanism drive planet carrier rotation, start laser welder simultaneously, boss inductance loop is along with planet carrier rotates together, in the time that planet carrier rotates to first paragraph circular arc weld seam original position, the boss of corresponding boss inductance loop triggers approach switch with it, laser welder starts welding, and first paragraph circular arc weld seam has welded the rear laser weld that automatically stops; In the time that planet carrier rotates to second segment circular arc weld seam original position, the boss of corresponding boss inductance loop triggers approach switch again with it, and laser welder starts welding, and second segment circular arc weld seam has welded the rear laser weld that automatically stops; In the time that planet carrier rotates to the 3rd section of circular arc weld seam original position, the boss of corresponding boss inductance loop triggers approach switch for the third time with it, and laser welder starts welding, and the 3rd section of circular arc weld seam welded the rear laser weld that automatically stops, drives structure stops operating, and planet carrier has welded.
The laser instrument of described laser welder can be optical fiber laser, carbon dioxide laser, video disc laser instrument, semiconductor pumped all solid state laser, lamp pump laser.
Automobile gearbox planet carrier welding method of the present invention, owing to having adopted laser automatic welding, makes it compared with prior art, has the following advantages and feature: 1, laser automatic welding, and even weld, is shaped attractive in appearance, and welding deformation is little, and welding quality is high.2, Laser Welding Speed is fast, and production efficiency is high.3,, when laser weld, can not produce ultraviolet ray, X ray impact is healthy.
