Embodiment 1

[0029] Such as figure 1 As shown, this embodiment includes: a five-axis machine tool platform 1, a welding spindle 2, a laser system 3, a mechanical sensor 4, a displacement sensor 5 and a control system, wherein the mechanical sensor 4 is installed on the welding spindle 2, and the displacement sensor 5 is installed on the Near the guide rail on the five-axis machine platform 1, the laser system 3 is installed on the five-axis machine platform 1, and the control system is respectively connected with the five-axis machine platform 1, the laser system 3, the force sensor 4, and the displacement sensor 5, and is used to control the Adjustment of axis machine tool platform 1, laser system 3, force sensor 4 and displacement sensor 5.

[0030] The five-axis machine tool platform 1 is a double-swing head mechanism with five-axis linkage in series, including X-axis, Y-axis, Z-axis, C-axis and S-axis. Among them, the X-axis, Y-axis, and Z-axis are moving axes, and the C-axis is rotati...

Embodiment 2

[0036] Embodiment 2 is a welding method using the micro-stirred welding system integrated with laser and mechanical dual sensors provided in Embodiment 1.

[0037] This embodiment includes the following steps:

[0038] The first step is to place the device to be welded on the five-axis machine tool platform, and after installation and fixation, control the movement of the X and Y axes through the control system to allow the laser sensor in the laser system to identify the starting point of the weld of the device to be welded;

[0039] In the second step, the laser system automatically identifies the welding seam of the device, and then saves the parameters of the welding seam track point into the corresponding database file;

[0040] In the third step, the staff writes the processing program in the control system and sets the welding process parameters;

[0041] The fourth step, after the above three steps are completed, press the welding start button in the control system, t...

Abstract

The invention discloses a micro stirring welding system integrating laser and mechanical sensors and a welding method. The micro stirring welding system integrating laser comprises a five-axis machine tool platform, a welding spindle, a laser system, the mechanical sensor, a displacement sensor and a control system, wherein the mechanical sensor is arranged on the welding spindle; the displacement sensor is arranged near a guide rail on the five-axis machine tool platform; the laser system is arranged on the five-axis machine tool platform; the control system is respectively connected with the five-axis machine tool platform, the laser system, the mechanical sensor and the displacement sensor and is used for controlling regulation on the five-axis machine tool platform, the laser system, the mechanical sensor and the displacement sensor. The micro stirring welding system completes butt and overlapping welding of an ultrathin aluminium sheet with a thickness of 0.2 to 1mm, a copper plate and other metals suitable for stirring welding, implements a mechanical and displacement dual-control motion system and functions of laser positioning, parameter fine adjustment and the like and can be used for welding a pin of a microchip and an ultrathin part.

Description

technical field [0001] The patent of the present invention relates to a micro-stirring welding system that can realize friction stir welding of ultra-thin light alloy metals, copper, etc., specifically a micro-stirring welding system and welding method that integrates laser and mechanical dual sensors. Background technique [0002] Aluminum alloy materials are favored by many industrial manufacturers due to the advantages of light weight, corrosion resistance, and easy forming. With the continuous improvement of the performance of this material, such as the emergence of new types of duralumin and super duralumin, it is widely used in aerospace, aerospace, Industrial manufacturing fields such as high-speed trains and high-speed ships have been more and more widely used. However, the large welding deformation of the traditional welding method is an important problem that plagues its development. Friction stir welding currently has two directions, one is the welding of super l...
