Embodiment 1

[0041] refer to Figure 1-Figure 6 , the present invention includes a machine platform 1, the machine platform 1 is a metal cabinet structure, the side is provided with an observation window 11 and a heat dissipation window 12, and an industrial computer 41 and a laser generator 32 are provided inside. The top surface of the machine platform 1 is a welding work surface, and a welding table 13 is provided. The present invention also includes a positioning mechanism 2, a welding mechanism, a cooling mechanism, a power supply mechanism 6 and a control mechanism.

[0042] The positioning mechanism 2 is used for positioning the laser welding head 31, and is arranged on the top surface of the machine table 1, and adopts an XYZ three-axis linkage method. Such as image 3 As shown, the positioning mechanism 2 includes an X-axis device 21 , a Y-axis device 22 , a Z-axis device 23 and a C-axis rotating shaft 24 . The X-axis device 21 is a hollow columnar structure, placed horizontall...

Embodiment 2

[0053] refer to Figure 7 The four-axis fiber laser welding equipment provided in this embodiment has the following improvements on the basis of Embodiment 1: In order to increase the stability of the connection between the Z-axis device 23 and the X-axis device 21, the Z-axis device 23 and the Z-axis slide An L-shaped reinforcing block 234 is added to the joint of the rail 233; in order to prevent the Y-axis device 22 from falling too low to damage the CCD industrial camera 34 or the laser welding head 31, a limit block 235 is provided at the bottom of the Z-axis slide rail 233. Setting the reinforcement block 234 can prevent the positioning mechanism 2 from being deformed or damaged due to the offset of the center of gravity, and can improve the positioning accuracy during welding; setting the limit block 235 can prevent the stroke of the Y-axis device 22 from being too low, and prevent the laser welding head 31 or CCD industrial camera from being too low. 34 is damaged by b...

Embodiment 3

[0055] refer to Figure 8 , The four-axis fiber laser welding equipment provided in this embodiment has the following improvements on the basis of Embodiment 2: a document storage box 16 is provided on the side of the machine 1 for placing documents such as operating procedures and production records.

[0056] The applicant of the present invention requires the operator to record the welding workpiece and the working state of the welding machine during production. The file storage box 16 is provided in this embodiment, and the operator can easily take the production record file to carry out the production process during the production process. Record.

Abstract

The invention provides a four-axis optical fiber laser welding device and belongs to the technical field of welding equipment. The four-axis optical fiber laser welding device comprises a machine table, a welding mechanism, a locating mechanism, a cooling mechanism, a power supply mechanism and a control mechanism. The locating mechanism comprises an X-axis device horizontally and fixedly connected with the top surface of the machine table, a Z-axis device perpendicularly connected with the top surface of the X-axis device, a Y-axis device perpendicularly connected with the side face of the Z-axis device and a C-axis rotary shaft connected with one end of the Y-axis device. The welding mechanism comprises a laser welding head arranged on the C-axis rotary shaft, a laser generator arrangedinside the machine table and a gas shielding device. A control system comprises an industrial personal computer arranged inside the machine table, a displayer, a keyboard and a mouse, wherein the displayer, the keyboard and the mouse are arranged beside the machine table and matched with the industrial personal computer for use. The four-axis optical fiber laser welding device can realize automatic welding, substantially reduces the manual workload and the requirement for the special technical skills, reduces human errors and the manpower requirement and improves the production efficiency andproduct quality.

Description

technical field [0001] The invention belongs to the technical field of welding equipment, and in particular relates to a four-axis optical fiber laser welding equipment. Background technique [0002] With the continuous development and growth of the company, the demand for products in the market is increasing day by day, and the productivity is facing huge challenges, so it is particularly important to improve productivity. The middle frame of the electric heating table products produced by our company has always been manually welded, but with the growth of market demand, the disadvantages of low manual welding efficiency are highlighted, and manual welding also has difficulties in welding, thermal expansion stress deformation of workpiece welding, and welding The quality is uneven, not beautiful and many other problems. Therefore, in order to improve productivity, improve product quality, ensure the consistency of product specifications in the mass production process, and ...
