[0031] In a typical embodiment of the present application, a tooling for adjusting the distance and angle between a laser welding torch and a weld tracking sensor is provided. As shown in the figure, it includes a laser welding torch mounting plate 4 and a weld tracking mounting plate 5. A rotating L-shaped bracket 6 is mounted on the weld tracking mounting plate 5, and the other side of the rotating L-shaped bracket 6 is connected to a sensor mounting plate 7, and the sensor mounting plate 7 is used for mounting a weld tracking sensor 8; Figures 1-5 As shown in the figure, it includes a laser welding torch mounting plate 4 and a weld tracking mounting plate 5. A rotating L-shaped bracket 6 is mounted on the weld tracking mounting plate 5, and the other side of the rotating L-shaped bracket 6 is connected to a sensor mounting plate 7, and the sensor mounting plate 7 is used for mounting a weld tracking sensor 8;
[0032] An arc-shaped hole 62 is machined on the rotating L-shaped bracket 6, and the weld tracking mounting plate 5 is connected to the rotating L-shaped bracket 6 through the arc-shaped hole 62 and can be rotated along the arc-shaped hole to adjust the angle; a long strip-shaped waist hole 72 is machined on the sensor mounting plate 7, and the weld tracking sensor can slide along the long strip-shaped waist hole to adjust the position.
[0033] Specifically, as shown in FIGS. Figure 1 、 2 The laser welding torch 9 is fixedly mounted on the laser welding torch mounting plate. One end of the laser welding torch mounting plate 4 is fixedly connected to the weld tracking mounting plate 5 through a mounting plate connecting screw 51. A plurality of connecting holes 52 arranged in multiple rows and columns are evenly formed on the weld tracking mounting plate 5. A rotating L-shaped bracket 6 is mounted at one end of the weld tracking mounting plate away from the laser welding torch mounting plate. The weld tracking mounting plate 5 is connected to the rotating L-shaped bracket 6 through the connecting holes 52. An arc-shaped hole 62 is formed at one end of the rotating L-shaped bracket 6 close to the weld tracking mounting plate. A wing nut 61 is arranged in the arc-shaped hole 62, and the wing nut 61 can slide along the arc-shaped hole 62, so as to adjust the relative angle between the laser welding torch mounting plate and the sensor mounting plate. After the arc-shaped hole 62 is aligned with some of the connecting holes 52 through the wing nut 61 and the wing nut is tightened, the relative position between the laser welding torch mounting plate and the weld tracking mounting plate can be fixed. In this embodiment, in order to ensure stable installation, a three-point surface connection is adopted between the weld tracking mounting plate 5 and the rotating L-shaped bracket 6. Among them, the laser welding torch mounting plate 4 and the weld tracking mounting plate 5 are installed at a 90° angle.
[0034] Specifically, as shown in FIGS. Figure 1 、 2 As shown in FIG. 5, a sensor mounting plate 7 is mounted at one end of the rotating L-shaped bracket 6 perpendicular to the plane where the arc-shaped hole is located. The rotating L-shaped bracket 6 and the sensor mounting plate 7 are fixedly connected through a bracket connecting screw 71, and the sensor mounting plate 7 is used for fixedly mounting a weld tracking sensor 8. In this embodiment, as shown in FIG. Figure 5 Two longitudinally parallel long strip-shaped waist holes 72 are formed on the sensor mounting plate 7, and the weld tracking sensor 8 is fixedly mounted on the long strip-shaped waist holes 72 through screws, which is convenient for adjusting the installation position of the weld tracking sensor, so as to change the relative distance between the weld tracking sensor and the laser welding torch.
[0035] To achieve the angle adjustment between the laser welding torch and the welding robot, as Figure 1 , 3 shown, on one side of the laser welding torch mounting plate 4, a rotary hinge block 2 and a transition hinge block 3 are installed. A connecting flange 1 is fixedly installed on the rotary hinge block 2. The connecting flange 1 is used to connect the flange of the welding robot and is the component for installing the entire tooling on the welding robot.
[0036] Specifically, as Figure 3 shown, on the side of the rotary hinge block 2 away from the transition hinge block, a connecting flange 1 for connecting with the flange arm of the robot is installed. The connecting flange 1 and the rotary hinge block 2 are fixedly connected by connecting flange screws 11. The transition hinge block 3 is installed between the rotary hinge block 2 and the laser welding torch mounting plate 4. One end of the transition hinge block 3 is fixedly connected to the laser welding torch mounting plate 4 through a transition connecting screw 41. At the other end, both the transition hinge block 3 and the rotary hinge block 2 are provided with a central hole 23 and the transition hinge block 3 and the rotary hinge block 2 are coaxially arranged. The two are connected by a fixing shaft 21 passing through the central hole. The transition hinge block and the rotary hinge block can rotate relative to the fixing shaft, thereby driving the laser welding torch mounting plate to rotate relative to the connecting flange, and further enabling the entire laser welding torch and the weld tracking sensor to rotate relative to the welding robot to adjust the angle of the welding torch. A number of axial through holes 24 evenly distributed around the central hole are machined on the rotary hinge block 2 and the transition hinge block 3. In this embodiment, as Figure 3 shown, 8 φ5.5 axial through holes are evenly distributed around the central hole of the rotary hinge block, and the angle between the center connection lines of every two adjacent holes is approximately 45°. 12 M5 threaded holes are evenly distributed around the central hole of the transition hinge block, and the angle between the center connection lines of every two adjacent holes is approximately 30°. By rotating the rotary hinge block and the transition hinge block, a indexing adjustment of every 45° - 30° = 15° can be completed, that is: the laser welding torch can be installed at an angle with an indexing adjustment of 15° around the rotary hinge block. When the appropriate angle is adjusted, the hinge block connection screws are passed through the axial through holes of the rotary hinge block and the transition hinge block to be tightened, and the installation position can be fixed.
[0037] In a preferred embodiment, the axial through holes on the rotary hinge block are set as the arc-shaped long holes as Figure 4 shown. By correspondingly adjusting the distribution of the screw holes on the transition hinge block, a stepless angle adjustment of 360° of the laser welding torch relative to the welding robot can be achieved, and the precise adjustment of the welding torch angle can be further realized, improving the laser welding effect.

Those of ordinary skill in the art should understand that the present invention can have various changes and modifications. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
