The two connecting rods An adjusting mechanism is provided above the connecting rod 9. By providing the adjusting mechanism, the structure for clamping the workpiece can be made to work when an independent power source is provided. The upper surfaces of the first carrier plate 2 and the second carrier plate 3 are symmetrically connected to two connecting blocks 14 front and back, and the connecting blocks 14 are U-shaped. A clamping mechanism is provided between the two connecting blocks 14. By providing the clamping mechanism, the workpiece can be stably clamped, and both flat and curved workpieces can be stably fixed. A pressure measuring mechanism is provided on the top left end of the base 1. The height of the pressure measuring mechanism is the same as that of the first carrier plate 2 and the second carrier plate 3. The pressure measuring mechanism can be used to monitor in real time whether the clamping of the workpiece is loose when the workpiece is clamped.

[0030] Specifically, the moving mechanism includes a connecting seat 4, a roller 5 and a screw 6. The connecting seat 4 is connected to the lower surfaces of the first carrier plate 2 and the second carrier plate 3. Rollers 5 are installed at the bottom of the two connecting seats 4. The connecting seat 4 at the right end of the base 1 is inserted and connected with a screw 6. The right end of the screw 6 is connected to a first motor 7. A channel with a diameter larger than the diameter of the screw 6 is reserved inside the connecting seat 4 at the left end of the base 1, so that the screw 6 can pass through the connecting seat 4 at the left end of the base 1 and is not connected to it. The model of the first motor 7 is selected according to actual needs. It controls the screw 6 to rotate, thereby driving the connecting seat 4 at the right end of the base 1 to move horizontally through the screw 6.

[0032] Furthermore, the adjustment mechanism includes a first serrated plate 12, a first rotating rod 13, a second serrated plate 15, a third serrated plate 16, a second rotating rod 17, a first connecting rod 18 and a second connecting rod 19, the first serrated plate 12 is located on the top front side of the connecting block 14, and the bottom end of the first serrated plate 12 is meshed with the screw 10, the top end of the first serrated plate 12 is connected to the first rotating rod 13, and the other end of the first rotating rod 13 passes through the connecting block 14, the outer surface of the first rotating rod 13 is connected to the second serrated plate 15, the bottom end of the second serrated plate 15 is meshed with the third serrated plate 16, and the bottom end of the third serrated plate 16 is connected to the second rotating rod 17, and the front and rear ends of the second rotating rod 17 are connected to the connecting block 14, and the outer surfaces of the first rotating rod 13 and the second rotating rod 17 are respectively movably connected with the first connecting rod 18 and the second connecting rod 19. When the second motor 11 controls the connecting rod 9 to rotate, the two screws 10 rotate synchronously. At this time, the screw 10 will drive the first serrated plate 12 to rotate. At the same time, under the transmission of the first rotating rod 13, the second serrated plate 15 and the first connecting rod 18 start to rotate, and the second serrated plate 15 will drive the third serrated plate 16 meshed at its bottom end to rotate. At this time, through the transmission of the second rotating rod 17, the second connecting rod 19 rotates synchronously.

[0033] Furthermore, the clamping mechanism includes a first clamping plate 20 and a second clamping plate 21, the first clamping plate 20 is connected to the inner ends of the first connecting rod 18 and the second connecting rod 19, the other end surface of the first clamping plate 20 is connected to the second clamping plate 21, and an arc groove is provided on the end surface of the first clamping plate 20 close to the second clamping plate 21. After the first connecting rod 18 and the second connecting rod 19 rotate, the first clamping plate 20 will be pushed to slide, and synchronously drive the second clamping plate 21 to slide, so as to clamp the workpiece that needs to be fixed. At the same time, by setting an arc groove on one end surface of the first clamping plate 20, the first clamping plate 20 or the second clamping plate 21 can be selected according to actual needs to clamp the workpiece with a flat surface or an arc shape.

[0034] Furthermore, the surface of one end of the first clamping plate 20 away from the second clamping plate 21 is connected to a mounting plate 24, the other end of the mounting plate 24 is connected to a rotating shaft 25, the outer surface of the rotating shaft 25 is connected to a side plate 26, and the front end of the side plate 26 is connected to the second clamping plate 21, so that the second clamping plate 21 can rotate relative to the first clamping plate 20 through the rotating shaft 25, thereby opening the combined structure of the first clamping plate 20 and the second clamping plate 21, making it convenient for the staff to choose the first clamping plate 20 or the second clamping plate 21 to clamp the workpiece.

[0035] Furthermore, the upper surfaces of the first clamping plate 20 and the second clamping plate 21 are both connected with a protruding plate 22, and fixing bolts 23 are inserted into the inside of the protruding plate 22. When the first clamping plate 20 and the second clamping plate 21 are in contact, the first clamping plate 20 and the second clamping plate 21 can be fixed by connecting the fixing bolts 23 to the protruding plate 22.

[0036] The method of using this embodiment is as follows: first, two workpieces that need to be laser welded are placed on the first carrier plate 2 and the second carrier plate 3 respectively, and then the second motor 11 is started to rotate the connecting rod 9. When the connecting rod 9 rotates, the adjusting mechanism is controlled by the screw 10 to start working, thereby pushing the combined structure of the first clamping plate 20 and the second clamping plate 21 to slide, thereby clamping the workpiece. When clamping the workpiece, the first clamping plate 20 or the second clamping plate 21 can be selected to clamp the workpiece according to the actual shape of the workpiece. After the workpiece is clamped, the first motor 7 is started to control the screw rod 6 to rotate, thereby sliding the connecting seat 4 at the right end of the base 1 to drive the second carrier plate 3 to slide toward the direction of the first carrier plate 2, thereby controlling the two workpieces to approach and making the welding surfaces fit together. After the welding surfaces fit together, the screw rod 6 continues to rotate, so that the second carrier plate 3 pushes the first carrier plate 2 to move until both move to the left end of the base 1.

[0037] Example 2

[0038] The structure of the clamping auxiliary device for laser welding of this embodiment is basically the same as that of the clamping auxiliary device for laser welding of embodiment 1, except that the pressure measuring mechanism includes a pressure sensor 27 and a mounting rod 28, the mounting rod 28 is threadedly connected to the top of the left end of the base 1, and the other end of the mounting rod 28 is connected to the pressure sensor 27, the height of the pressure sensor 27 is the same as the height of the first carrier plate 2 and the second carrier plate 3, the model of the pressure sensor 27 is selected according to actual needs, and a display screen for displaying the pressure value is provided on the surface of the pressure sensor 27, so that the clamping condition of the workpiece can be monitored in real time during welding, so as to remind when it becomes loose (see Figure 6 ).

[0039] The method of using this embodiment is as follows: when the first carrier plate 2 and the second carrier plate 3 move to the left end of the base 1, the first carrier plate 2 will squeeze the pressure sensor 27. At this time, the display screen on the surface of the pressure sensor 27 displays the pressure value. When a pressure signal appears, the first motor 7 automatically turns off and stops the rotation of the screw rod 6 through the built-in controller, so that the surface pressure value of the pressure sensor 27 remains constant. When the clamped workpiece becomes loose, the surface pressure of the pressure sensor 27 will change, and the staff can observe and adjust it in time through the display screen.
