DETAILED DESCRIPTION
[0024] The following collection is attached Figure 1 -Attached Figure 4 , further details of this application are given.
[0025] The embodiment of the present application is: a laser welding device for processing a bearing seat, referring to Figure 1 and Figure 2, including a welding machine body 1. In this embodiment, the welding machine body 1 is a laser welding machine in the prior art. A numerical control manipulator 2 is provided on one side of the welding machine body 1 for driving a welding gun 11 in the welding machine body 1 to move. In this embodiment, four welding guns 11 are provided. The numerical control manipulator 2 is a numerical control manipulator 2 in the prior art. A mounting block 3 is installed at the end of the movable end of the numerical control manipulator 2, and the mounting block 3 is set in a rectangular parallelepiped shape.
[0026] Reference Figure 2 , Figure 3 and Figure 4 , an adjustment assembly 4 for adjusting the position of the welding gun 11 is provided between the welding gun 11 and the mounting block 3. The adjustment assembly 4 includes a rotating motor 41, which is fixedly connected to the mounting block 3, and a plurality of connecting blocks 42 are fixedly connected to the end face of the output shaft of the rotating motor 41. In this embodiment, the connecting blocks 42 are provided in four numbers and are arranged around the axis of the output shaft of the rotating motor 41. An adjusting gear 43 is rotatably connected to the connecting block 42, and a placing rod 44 is fixedly connected to the end face of the adjusting gear 43. The welding gun 11 corresponds to the placing rod 44 one by one, and the welding gun 11 is fixedly connected to one end of the placing rod 44 away from the adjusting gear 43. A rotating motor 46 is fixedly connected to the end face of the output shaft of the rotating motor 41, and a screw 45 is fixedly connected to the output shaft of the rotating motor 46, and the screw 45 is meshed with the four adjusting gears 43. The screw 45 is coaxially arranged with the output shaft of the rotating motor 46, and the screw 45 is coaxially arranged with the output shaft of the rotating motor 41.
[0027] Therefore, the rotating motor 41 can be controlled to rotate, so that the rotating motor 41 drives the four mounting blocks 3 to rotate around the axis of the rotating motor 41, thereby driving the placement rod 44 to rotate, and then the multiple welding guns 11 perform rotational welding along with the placement rod 44.
[0028] At the same time, when it is necessary to change the welding trajectories of multiple welding guns 11 synchronously so that multiple welding guns 11 can weld the patch in multiple circular trajectories, the rotating motor 46 can be controlled to rotate, so that the rotating motor 46 drives the screw 45 to rotate. Since the screw 45 is engaged with the adjusting gear 43, the screw 45 can drive the multiple adjusting gears 43 to rotate, so that the multiple placement rods 44 rotate toward the axis of the screw 45 or away from the axis of the screw 45, thereby synchronously changing the welding position of the welding gun 11.
[0029] A mounting plate 5 is provided on one side of the mounting block 3. The mounting plate 5 is set as an arc-shaped plate, and the inner arc surface of the arc-shaped plate faces one side of the mounting block 3. A welding hole 51 for welding is opened on the mounting plate 5. A supporting foot 6 is fixedly connected to the mounting plate 5. The supporting foot 6 is an elastic supporting foot 6 with a certain deformation ability in the prior art. Two supporting feet are set and located on the outer arc surface of the arc-shaped plate.
[0030] The mounting plate 5 is provided with a plurality of abutting feet 7, and in this embodiment, four abutting feet 7 are provided. The abutting feet 7 are used to press the patch block tightly against the patching location, and the side of the abutting feet 7 away from the mounting block 3 is rotatably connected to an abutting wheel 71. A connecting mechanism 8 is provided between the abutting feet 7 and the mounting plate 5 for connecting the two.
[0031] The connecting mechanism 8 includes a mounting ring 81 fixedly connected to the mounting plate 5, a rotating ring 82 is rotatably connected inside the mounting ring 81, and the rotating ring 82 is coaxially arranged with the mounting ring 81. The rotating ring 82 is coaxially arranged with the mounting ring 81, a cross rod 83 is fixedly connected inside the mounting ring 81, and the center of the cross rod 83 coincides with the axis of the mounting ring 81. The abutting foot 7 is fixedly connected to the cross rod 83, and a rotating assembly 84 for driving the rotating ring 82 to rotate is provided on the mounting ring 81.
[0032] The rotating assembly 84 includes a driving motor 841 fixedly connected to the mounting plate 5, and the driving motor 841 is located on the side of the mounting ring 81 close to the mounting block 3. The output shaft of the driving motor 841 passes through the mounting ring 81 and is fixedly connected to a driving gear 842, and the driving gear 842 is coaxially arranged with the output shaft of the driving motor 841. The driving gear 842 is rotatably connected in the mounting plate 5, and a tooth groove 821 arranged around the circumference of the rotating ring 82 is opened on the outer wall of the rotating ring 82, and the driving gear 842 meshes with the tooth groove 821.
[0033] In this way, the driving motor 841 can be started, so that the driving motor 841 drives the driving gear 842 to rotate, and the driving gear 842 drives the rotating ring 82 to rotate in the mounting ring 81 through the tooth groove 821, thereby driving the cross rod 83 to rotate. At the same time, the rotating motor 41 can be controlled so that the rotating motor 41 drives the welding gun 11 and the cross rod 83 to rotate synchronously, so that the laser emitted by the welding gun 11 remains in the gap of the cross rod 83, so that each welding gun 11 can complete uninterrupted and continuous welding on the four sides of the patch through the gap on the cross rod 83.
[0034] At the same time, in order to reduce the influence of the mounting plate 5 on the subsequent welding during the welding process, a moving member 9 is provided on the mounting block 3 for driving the mounting plate 5 to move. The moving member 9 is set as a positioning motor, the positioning motor is fixedly connected to the mounting block 3, and the output shaft of the positioning motor is fixedly connected to the corner of the mounting plate 5.
[0035] The implementation principle of the embodiment of the present application is: the manipulator can be controlled so that the manipulator presses the patch block against the repaired part of the bearing seat through the mounting block 3 and the abutment wheel 71 on the abutment foot 7, and limits the abutment force of the abutment foot 7 on the patch block through the support rod.
[0036] Then, by adjusting the rotating motor 46, the welding gun 11 is aligned with the edge of the patch, and then the welding gun 11 and the rotating motor 41 are started to perform welding. At the same time, by controlling the driving motor 841, the driving motor 841 drives the cross bar 83 to rotate, so that the cross bar 83 and the rotating motor 41 rotate synchronously, and then the laser emitted by the welding gun 11 is kept in the gap of the cross bar 83, so that each welding gun 11 can complete uninterrupted continuous welding around the patch through the gap on the cross bar 83, and finally the edge of the patch is initially adhered to the notch of the bearing seat. The patch is initially fixed at the notch, and then the welding and the rotation of the cross bar 83 and the rotating motor 41 are stopped.
[0037] Then, the positioning motor is controlled to move the mounting plate 5 out of the welding range of the welding gun 11, and then the rotating motor 46 is started to repeatedly change the welding position of the welding gun 11, and the rotating motor 41 is started again, thereby causing the welding gun 11 to melt and repair the entire patch.
