Example Embodiment

[0037] Example 1:

[0038] This embodiment provides a laser welding workload, such as figure 1 As shown, it includes: the tooling bottom plate 1, the positioning pin assembly 2, the positioning clamp assembly 3, and the weld positioning clamping assembly 4; and the positioning pin assembly 2, positioning clamping assembly 3 and weld positioning clamping assembly 4 Both are connected to the workplate 1;

[0039] Wherein, the positioning pin assembly 2 is used in conjunction with the positioning hole 5 on the workpiece 6, the positioning clamp assembly 3 for clamping the surface of the workpiece 6, by positioning pin assembly 2, positioning clamping assembly 3 to perform the workpiece 6 The clamping fixation; and the weld positioning clamp assembly 4 for fixing the weld of the workpiece 6.

[0040] In this embodiment, the positioning pin assembly 2, the positioning clamping assembly 3, and the weld positioning clamping assembly 4 may have a plurality of, which can be attached to the...

Example Embodiment

[0050] Example 2:

[0051] This embodiment differs from the embodiment 1 only, such as Figures 3A-3B As shown, the positioning clamp assembly 3 also includes:

[0052] The first clamping position block 31 is connected to the lower surface of the other end of the workpiece clamping arm 35;

[0053] The second clamping positioning block 32 is connected to the workpiece positioning the upper surface of the adapter plate 33, and corresponds to the first clamping position block 31, the first clamping positioning block 31 and the second clamping A clamping space for clamping the workpiece 6 is formed between the positioning block 32; when the power output shaft of the clamping air cylinder 38 is rotated by the rotating arm 39, the first clamping position block 31, the second clip The tight block 32 is in contact with the surface of the workpiece 6 to achieve clamping for the workpiece 6; at the same time, the first clamping position block 31 is connected to the workpiece clamp arm 35, a...

Example Embodiment

[0059] Example 3:

[0060] This example is only in the different embodiments of the first or 2, such as Figures 5A-5B As shown, in the weld positioning clamping assembly 4, the upper weld clamping block 41 is provided with a receiving cavity 411 for receiving the weld, and the upper and lower housing 411, 4111. The aperture is greater than the lower opening 4112 pore size, and the integral is a flared structure inclined with respect to the horizontal plane. Preferably, the angle alpha formed by the outer peripheral surface of the receiving chamber 411 is satisfied: 60 ° ≤ α ≤ 85 ° (preferably α is 75 °), thereby, even if the laser acts at the weld, there is a certain angle, since the upper opening 4111 of the receiving chamber 411 is relatively large, the upper space is relatively large, and the laser is not covered by the upper weld. The upper portion of 41 occlusion, which can still be irradiated on the weld at the bottom of the receiving chamber 411 to complete the welding.

Abstract

The invention discloses a laser welding tool. The laser welding tool comprises a tool bottom plate, a positioning pin assembly, a positioning and clamping assembly and a welding seam positioning and clamping assembly, wherein the positioning pin assembly, the positioning and clamping assembly and the welding seam positioning and clamping assembly are all connected with the tool bottom plate, the positioning pin assembly is used for being matched with a positioning hole in a workpiece, the positioning and clamping assembly is used for clamping the surface of the workpiece, the workpiece is clamped and fixed through the positioning pin assembly and the positioning and clamping assembly, and the welding seam positioning and clamping assembly is used for fixing a welding seam of the workpiece. According to the laser welding tool, movement of the welding seam can be avoided by fixing the position of the welding seam, so that the gap at the welding seam is controlled, it is ensured that a laser beam only works at the welding position, and the requirements for the laser self-fusion welding process and quality are met.

Description

technical field [0001] The invention relates to the technical field of laser welding, in particular, the invention relates to a laser welding tool. Background technique [0002] Traditionally, the resistance welding process and resistance welding tooling are mainly used in the welding position of the inner door panel and the door frame reinforcement plate of the body-in-white. After the development of industry and the progress of science and technology, the traditional resistance welding process is gradually replaced by the laser flight welding process. . Among them, the white body refers to the original state of the body that has not been processed and painted. Traditional resistance spot welding compresses the weldment between two electrodes, applies current, and uses the resistance heating effect generated by the current flowing through the contact surface of the workpiece and the adjacent area to heat it to a molten or plastic state, thereby achieving metal bonding and ...
