Detailed Implementation

[0019] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0020] Please see Figures 1 to 3 This embodiment provides a flip-type laser welding machine clamping mechanism, including a support plate 1, an annular track 2, a rotating plate 3, a clamping plate 4, a first magnet 5, and a second magnet 6. The support plate 1 is used to connect and support other components, the annular track 2 provides connection support for the rotating plate 3, the rotating plate 3 rotates to adjust the angle of the clamping plate 4, the clamping plate 4 is used to clamp the item to be laser welded, and the first magnet 5 and the second magnet 6 are used to magnetically connect the rotating plate 3 and the clamping plate 4.

[0021] One end of the support plate 1 forms a cylindrical connecting part 1a. The annular track 2 is arranged coaxially with the connecting part 1a and is fixedly connected to the support plate 1. Preferably, in this embodiment, the annular track 2 and the support plate 1 are riveted together.

[0022] Multiple rotating plates 3 are rotatably connected at one end to the connecting part 1a, and slidably disposed in the annular track 2 at the other end. Specifically, the clamping mechanism of this flip-type laser welding machine also includes a locking pin 7, which includes a threaded part 7a and an abutting part 7b. The threaded part 7a is disposed in the annular track 2 and threadedly connected to the rotating plate 3. The abutting part 7b is fixedly connected to the side of the threaded part 7a away from the rotating plate 3 and abuts against one end face of the annular track 2. Preferably, the locking pin 7 also includes a turning part 7c, which is fixed to the side of the threaded part 7a away from the abutting part 7b. The surface of the turning part 7c is knurled to increase the friction between the operator and the turning part 7c and prevent slippage. Turning the locking pin 7 causes the abutting part 7b to disengage from the support plate 1. At this time, the rotating plate 3 can rotate around the connecting part 1a. After adjusting the rotating part to a suitable angle, the locking pin 7 is turned again to make the abutting part 7b abut against the support plate 1. At this time, the rotating plate 3 is locked and cannot move.

[0023] One end of the clamping plate 4 is rotatably connected to the connecting part 1a. Preferably, the clamping mechanism of the flip-type laser welding machine further includes clamping bolts 8. The clamping plate 4 extends to one side to form two oppositely arranged clamping parts 4a, and a clamping opening is formed between the two oppositely arranged clamping parts 4a. The clamping bolts 8 are threadedly connected to one of the clamping parts 4a, and the clamping bolts 8 are used to clamp the object to be laser welded. More preferably, the two oppositely arranged clamping parts 4a are arranged in multiple groups along the length direction of the clamping plate 4, and multiple clamping bolts 8 are provided. Each group of clamping parts 4a is connected to at least one clamping bolt 8. Multiple groups of clamping parts 4a can clamp the object to be laser welded at multiple points, making the clamping more stable.

[0024] Multiple first magnets 5 are fixed one by one to the side of multiple rotating plates 3 near the clamping plate 4, and second magnets 6 are fixed to the side of the clamping plate 4 near the rotating plate 3. The first magnets 5 and second magnets 6 are positioned correspondingly and attract each other. The clamping plate 4 can be rotatably switched to correspond with different rotating plates 3 to change the position of the clamping plate 4. Therefore, when it is necessary to change the position of the clamping plate 4, simply rotate the clamping plate 4 with a little force to make it correspond with another rotating plate 3. The position of the rotating plates 3 can be adjusted in advance according to actual needs, and multiple rotating plates 3 can be set up according to the number of times the angle needs to be adjusted for the object to be laser welded. It should be noted that the welding laser beam of the laser head can generally move in a plane, so with the rotatable clamping plate 4, welding of more complex paths can be achieved. Preferably, the clamping plate 4 and multiple rotating plates 3 are respectively disposed on both sides of the support plate 1. Furthermore, the clamping mechanism of the flip-type laser welding machine also includes two fixing nuts 9, which are threadedly connected to the connecting part 1a. One fixing nut 9 is disposed on the side of the rotating plate 3 away from the support plate 1. This fixing nut 9 provides a limit for the rotating plate 3 to prevent the rotating plate 3 from disengaging from the connecting part 1a. The other fixing nut 9 is disposed on the side of the clamping plate 4 away from the support plate 1. This fixing nut 9 provides a limit for the clamping plate 4 to prevent the clamping plate 4 from disengaging from the connecting part 1a.

[0025] Preferably, the support plate 1, the annular track 2, the rotating plate 3, and the clamping plate 4 are arranged in two sets, which can clamp the items to be laser welded from both sides, making the clamping more stable. Furthermore, the clamping mechanism of the flip-type laser welding machine also includes a fixing plate 10, with two support plates 1 fixedly connected to both ends of the fixing plate 10.

[0026] In summary, the flip-type laser welding machine clamping mechanism provided by this utility model requires setting a corresponding number of rotating plates 3 according to the number of rotations of the object to be laser welded before use. The angle of each rotating plate 3 is adjusted according to the rotation position each time. The position of the rotating plate 3 remains unchanged during laser welding. After each laser welding is completed, only the clamping plate 4 needs to be rotated to the position of the next rotating plate 3 to perform the next laser welding. By performing the above steps one by one to rotate the clamping plate 4 and perform laser welding, a series of welding processes are completed. After that, when replacing the object that has not been laser welded, only the position of the rotating plate 3 needs to be adjusted before the first laser welding. After that, each adjustment only requires rotating the clamping plate 4, which greatly improves the efficiency of the laser welding process.
