[0030] In this embodiment, the triangular centering clamping mechanism includes a pressure sensor 5 fixedly embedded at the top center of the bearing positioning platform 4, a servo control component, three threaded rods 6 rotatably mounted on the connecting frame 2 and distributed in a ring shape, three transmission bevel gears 7 fixedly sleeved on opposite ends of the three threaded rods 6 in sequence, and three positioning rods 8 threadedly connected to the three threaded rods 6 in sequence;

[0031] Furthermore, the servo control assembly includes a servo motor 9 fixedly mounted on the outer wall of the bottom center of the bearing positioning platform 4 and a driving bevel gear 10 fixedly sleeved on the output shaft of the servo motor 9, and the three transmission bevel gears 7 are all meshed with the driving bevel gear 10;

[0032] Furthermore, three annularly distributed slideways 11 are provided on the top of the bearing positioning platform 4, and the outer walls of the three positioning rods 8 are slidably connected to the inner walls of the three slideways 11 respectively. A single-chip microcomputer 12 is fixedly installed on the top outer wall of the bearing positioning platform 4, and the pressure sensor 5 and the servo motor 9 are both electrically connected to the single-chip microcomputer 12;

[0033] During the specific implementation of this embodiment: when the bearing to be welded is placed on the bearing positioning platform 4, the pressure sensor 5 senses the pressure generated and transmits the positioning signal to the single-chip microcomputer 12, which controls the servo motor 9 to run. The servo motor 9 controls the driving bevel gear 10 to rotate, and then the three transmission bevel gears 7 meshing with the driving bevel gear 10 control the three threaded rods 6 to rotate synchronously. Then, under the limit of the three slideways 11, the three positioning rods 8 threadedly connected with the three threaded rods 6 will automatically move toward the center, so that bearings of different specifications can be centered and clamped, thereby achieving the effect of intelligent and automatic clamping, which can effectively avoid the movement of the bearings during welding and improve the welding stability and welding accuracy.

[0034] Example 2, reference Figure 1-2 and Figure 5 , This embodiment is optimized on the basis of embodiment 1, specifically: a stable welding device for a fan bearing, further comprising an angle-adjustable welding gun mechanism and a rotating mechanism;

[0035] In this embodiment, the angle-adjustable welding gun mechanism includes a self-locking driver, an angle adjustment shaft 13 rotatably mounted on the upper portion of the connecting frame 2, an angle adjustment seat 14 fixedly connected to the angle adjustment shaft 13, and a laser welding gun 15 fixedly mounted on the angle adjustment seat 14;

[0037] When the angle-adjustable welding gun mechanism is in use: the stepper motor 16 drives the worm 17 to rotate, and then the worm wheel 18 meshing with the worm 17 drives the angle adjustment seat 14 connected to the angle adjustment shaft 13 to rotate, so that the welding angle of the laser welding gun 15 can be flexibly adjusted to meet the diverse needs of multi-angle welding of different bearings;

[0040] In addition, in order to ensure that the electrical components installed on the bearing positioning platform 4 and the electric telescopic rod 19 are powered normally in the subsequent rotating state, a corresponding electric slip ring can be installed on the electric telescopic rod 19;

[0041] When the rotating mechanism is in use: the bearing processing height on the bearing positioning platform 4 can be flexibly adjusted through the electric telescopic rod 19, and the worm 17 is driven to rotate by the stepping motor 16, and then the worm wheel 18 engaged with the worm 17 will drive the rotating frame 3 connected to the top of the electric telescopic rod 19 to rotate, so that during the welding process, the bearing can be rotated, and then its surface can be evenly welded, thereby improving the welding quality and welding efficiency.

[0042] The use process of the present invention is as follows: first, when the bearing to be welded is placed on the bearing positioning platform 4, the pressure sensor 5 senses the pressure generated, and at this time, the positioning signal will be transmitted to the single-chip microcomputer 12, and the single-chip microcomputer 12 controls the servo motor 9 to run. At this time, the servo motor 9 controls the driving bevel gear 10 to rotate, and then the three transmission bevel gears 7 meshing with the driving bevel gear 10 will control the three threaded rods 6 to rotate synchronously, and then under the limit of the three slideways 11, the three positioning rods 8 threadedly connected with the three threaded rods 6 will automatically move toward the center, and bearings of different specifications can be centered and clamped, thus achieving the effect of intelligent automatic clamping, which can effectively avoid the movement of the bearing during welding, and improve the welding stability and welding accuracy;

[0043] Secondly, the worm 17 is driven to rotate by the stepper motor 16, and then the worm wheel 18 meshing with the worm 17 drives the angle adjustment seat 14 connected to the angle adjustment shaft 13 to rotate, so that the welding angle of the laser welding gun 15 can be flexibly adjusted to meet the diversified needs of multi-angle welding of different bearings, and the bearing processing height on the bearing positioning platform 4 can be flexibly adjusted by the electric telescopic rod 19;

[0044] Finally, after the adjustment is completed, the worm 17 is driven to rotate by the stepper motor 16, and then the worm wheel 18 engaged with the worm 17 drives the rotating frame 3 connected to the top of the electric telescopic rod 19 to rotate, so that during the welding process, the bearing can rotate, and then its surface can be evenly welded, thereby improving the welding quality and welding efficiency.
