Embodiment Construction

[0018] combine figure 1 , figure 2 , a kind of laser welding method of automobile sunroof guide rail, the steps are as follows:

[0019] 1. Design the tool coordinate system: connect the laser 1 to the laser head 3 through the optical fiber 2, use the robot 4 tool coordinates to set a new coordinate system and coordinate origin, and set the focus position of the laser spot focused by the laser head 3 as the tool coordinates of the robot The origin, the 3 axis of the laser head is the Z axis, and the vertical plane of the laser head 3 is used as the XY plane. Set this coordinate system to solve the tracking problem of U-shaped welds. This method can also solve the problem of special welds whose weld surface is not on the horizontal plane. Welding problem; laser 1 is a fiber laser, carbon dioxide laser, disk laser, semiconductor-pumped all-solid-state laser or lamp-pumped laser.

[0020] 2. Fix the workpiece: fix the workpiece 5 on the base 7 with self-made tooling 6, support...

Abstract

A laser welding method for an automobile skylight guide rail comprises the following steps of (1), designing a tool coordinate system, (2), fixing workpieces, (3), starting mechanical arm demonstration, (4), placing a height standard block, (5), lowering power at corners of the workpieces, (6), setting parameters, and (7), carrying out welding. According to the method, the surface appearance of weld joint can be controlled precisely, the burning loss phenomenon at the corners of the workpieces can be reduced, the weld joint is even and attractive after welding, secondary machining is not needed, and the welding method is simple and easy to achieve.

Description

technical field [0001] The invention belongs to the field of welding technology, and in particular relates to a laser welding method for an automobile sunroof guide rail. Background technique [0002] The car sunroof guide rail is the key component of the car sunroof, and the car sunroof is an important part of the car. In the Chinese market, many automobile manufacturers have begun to introduce supporting projects for sunroofs. At present, the cars of many manufacturers have launched the sunroof version of the car. Due to the particularity of the welding of automotive sunroof guide rails, traditional welding methods have been difficult to meet its production needs. The U-shaped weld is a relatively difficult welding shape in the welding process, which virtually increases the difficulty of production. U-shaped welds are prone to weld surface defects during the welding process. How to solve the problem of U-shaped welds while improving welding speed and welding quality has...
