Description

Technical Field

[0001] The utility model relates to the technical field of iron core welding, in particular to an iron core welding device which is convenient for fitting and positioning. Background Art

[0002] Laser welding of iron cores utilizes a high-energy-density laser beam as a heat source, a technique considered an application of laser welding technology. This technology offers advantages such as high efficiency, precision, environmental friendliness, strong applicability, significant potential for automation and intelligentization, and high cost-effectiveness, making it a key development direction in the motor manufacturing industry.

[0003] Compared with traditional welding processes, laser welding significantly improves productivity with its fast welding speed, shortens production cycle, and makes the manufacture of motor cores more efficient; laser welding technology, with its high energy density and precise control capabilities, can achieve precise welding of silicon steel sheets in an extremely small heat-affected zone, ensuring the mechanical properties of the welded joint, reducing welding deformation, and improving the overall accuracy and reliability of the motor core.

[0004] For example, the motor stator core laser welding device with application number 202221826004.1 has a rotating table driven by a stepper motor, with an adjustable rotation angle, and higher welding precision. The sliding cooperation between the guide block and the guide groove provides a guide for the rotation of the rotating table, which improves the smoothness of the rotating table. The welding part of the motor core is rotated between the two protective side plates, and the welding part of the motor core is protected by the two protective side plates, which improves its safety performance during use. The rodless cylinder pushes the transmission seat through the inside of the channel, driving the movement of the laser welding head. The laser welding head laser welds the welding part of the motor core from top to bottom, which has high welding efficiency and improves processing efficiency. However, the device still has certain defects;

[0005] During the welding process of the iron core, the iron core is not fixed and limited, so that the iron core is easily deflected under the action of external force, thereby affecting the welding quality of the iron core.

[0006] Therefore, we propose a core welding device that is easy to fit and position, so as to solve the above problems. Utility Model Content

The center line of the limiting threaded sleeve 8 coincides with the center line of the threaded shaft 7, and the limiting threaded sleeve 8 is threadedly connected to the threaded shaft 7. The position of the limiting threaded sleeve 8 can be adjusted by rotating the limiting threaded sleeve 8. When installing the iron core, the iron core is passed through the threaded shaft 7 and abutted against the limiting threaded sleeve 8. After the iron core is fixed, the limiting threaded sleeve 8 is rotated away from the iron core, so that when the iron core is welded, the limiting threaded sleeve 8 will not hinder it.

Blocks 22 are installed on the left and right sides of the threaded shaft 7. The movable rod 20 is located inside the telescopic spring 19, and when the first electromagnetic block 18 is energized, the movable rod 20 can be moved to close to the first electromagnetic block 18, completing the contraction and fixation of the movable rod 20, thereby completing the contraction and fixation of the second electromagnetic block 21. When the first electromagnetic block 18 is de-energized, the movable rod 20 can move outward under the action of the rebound force of the telescopic spring 19, driving the second electromagnetic block 21 on the movable rod 20 to move outward until it abuts against the inner wall of the iron core.

[0037] Working principle: When using the iron core welding device that is easy to fit and position, first, when installing the iron core, the iron core is passed through the threaded shaft 7 and abutted against the limiting threaded sleeve 8, and then the first electromagnetic block 18 is powered off, and the movable rod 20 can move outward under the action of the rebound force of the telescopic spring 19, driving the second electromagnetic block 21 on the movable rod 20 to move outward until it abuts against the inner wall of the iron core. When the second electromagnetic block 21 abuts against the inner wall of the iron core, the second electromagnetic block 21 is powered on, and the second electromagnetic block 21 is The iron core is adsorbed, and then the threaded rod 13 is rotated. The threaded rod 13 drives the movable plate 14 to move downward, and the movable plate 14 drives the connecting bar 15 and the positioning block 16 to move downward, so that the positioning block 16 fixes the movable rod 20 between the positioning block 16 and the stop block 22, completing the fixation of the movable rod 20, making the movable rod 20 unable to move, and thus making the second electromagnetic block 21 on the movable rod 20 unable to move, thereby completing the fixation of the iron core, so that the iron core will not be moved by force during welding, thereby improving the welding quality of the iron core.

[0038] After the core is secured, the limiting threaded sleeve 8 is rotated away from the core so that it does not obstruct the core during welding.
