As used herein, unless the context clearly indicates otherwise, the singular form is also intended to include the plural form. In addition, it should be understood that when the terms "comprising" and / or "including" are used in this specification, they indicate the presence of features, steps, operations, devices, components and / or combinations thereof. Based on the embodiments in the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0035] Example 1

[0036] In a typical embodiment of the present application, an adjustable composite fixture for a laser welding gun and an arc welding gun is provided, such as Figure 1-6 As shown, it includes a laser welding gun fixture 2 and an arc welding gun fixture 4, and both the laser welding gun fixture 2 and the arc welding gun fixture 4 are equipped with a displacement slide 1 for adjusting the distance; an arc welding gun angle adjustment mechanism 5 is installed on one side of the arc welding gun fixture 4, and the arc welding gun angle adjustment mechanism 5 is connected to the laser welding gun fixture 2 through an arc plate connecting plate 3.

[0037] Specifically, if Figure 3 As shown, the displacement slide 1 includes a slide base plate 13, with a first end plate 12 and a second end plate 15 fixedly connected at both ends of the slide base plate 13. A module guide rail 18 and a mounting plate 17 are mounted on one side of the slide base plate, and the mounting plate 17 is slidably connected to the module guide rail 18. The first end plate 12, the second end plate 15, and the module guide rail 18 are all fixed to the slide base plate 13 by screws. Locking plates 14 are mounted on both sides of the slide base plate 13 by screws.

[0038] At the same time, a screw rod 16 parallel to the module guide rail is passed across the mounting plate 17. The screw rod 16 passes through the first end plate 12, the mounting plate 17, and the second end plate 15 in sequence, and is threadedly connected to the mounting plate 17. The rotation of the screw rod 16 drives the mounting plate 17 to move linearly along the module guide rail 18. A knurled handle 11 is installed at one end of the screw rod 16 passing through the first end plate. The knurled handle 11 is fixedly connected to the screw rod 16 by a screw. Manually rotating the knurled handle can drive the mounting plate to move linearly along the module guide rail. When the mounting plate is adjusted to the appropriate position, the position of the mounting plate can be fixed by tightening the slide base plate with a locking bolt passing through the threaded hole of the locking plate. In this embodiment, the module guide rail cooperates with the mounting plate to, on the one hand, limit the rotation of the mounting plate, so that the screw rod rotation drives the mounting plate to move linearly. On the other hand, it guides the movement of the mounting plate.

[0039] like Figure 1 As shown, two sets of displacement slides 1 are fixedly mounted on the laser welding gun fixture 2, wherein the first set of displacement slides is used to adjust linear motion in a first direction, and the second set of displacement slides is used to adjust linear motion in a second direction, the second direction being perpendicular to the first direction. The two sets of displacement slides are connected by a slide L-shaped connecting frame 6. In this embodiment, the slide base plate of the first set of displacement slides is fixedly connected to the laser welding gun fixture via screws, and the two perpendicular surfaces of the slide L-shaped connecting frame are fixedly connected to the mounting plate of the first set of displacement slides and the mounting plate of the second set of displacement slides, respectively, thereby achieving displacement adjustment of the laser welding gun fixture in the first and second directions, and further achieving adjustment of the relative distance between the laser welding gun fixture and the arc welding gun fixture in two directions.

[0040] Specifically, the laser welding gun fixture 2 includes a laser head connecting plate 22 for connecting to the laser welding gun and a plurality of slide connecting plates for limiting the position of the laser welding gun. The plurality of slide connecting plates are fixedly connected to the laser head connecting plate 22 to form a four-sided enclosed structure, and the laser welding fixture is installed inside the enclosed structure and fixedly connected to the laser head connecting plate. Figure 4 As shown, a robot flange 21 is fixedly connected to the outside of the laser head connecting plate 22, and the laser welding gun fixture 2 is installed on the welding robot through the robot flange 21. The robot flange can be connected to the robot flange arm or installed in combination with other forms of mounting parts.

[0041] In this embodiment, the plurality of slide connection plates are respectively a first slide connection plate 23 installed on one side of the laser head connection plate, a second slide connection plate 24 installed on the opposite side of the laser head connection plate, and a third slide connection plate A25 and a third slide connection plate B26 installed on the other side of the laser head connection plate. The third slide connection plate A25 is installed above the third slide connection plate B26. One end of the third slide connection plate A25 and the third slide connection plate B26 are fixedly connected to the laser head connection plate 22, and the other end are fixedly connected to the second slide connection plate 24. Figure 1 、 4 As shown, the laser head connecting plate 22 is fixedly connected to the robot flange 21, the first slide connecting plate 23, the third slide connecting plate A25, and the third slide connecting plate B26 by screws. The second slide connecting plate 24 is fixedly connected to the first slide connecting plate 23, the third slide connecting plate A25, and the third slide connecting plate B26 by screws. The laser welding gun fixture 2 is mounted on the slide base plate of the first displacement slide via the second slide connecting plate 24. In this embodiment, in order to avoid the camera connection module on the side of the laser head, the third slide connecting plate A and the third slide connecting plate B are arranged in an upper and lower manner. The two are respectively connected to the laser head connecting plate 22 and the second slide connecting plate 24 to ensure a tight connection.

[0042] like Figure 2 As shown, the laser welding gun fixture is used to limit the laser welding gun 7 between the laser head connecting plate 22 and multiple slide connecting plates, and is connected to the laser head connecting plate 22 by screws, thereby achieving the positioning and installation of the laser welding gun 7.

[0043] In order to adjust the relative angle between the laser welding gun and the arc welding gun, in this embodiment, the arc welding gun angle adjustment mechanism 5 is fixedly connected to the laser welding gun clamp 2 on one hand, and to the arc welding gun clamp 4 on the other hand. Figure 1 、 2 As shown, an arc-shaped connecting plate 3 is fixedly installed on the outer side surface of the slide base plate of the second group of displacement slides. The arc-shaped connecting plate is an L-shaped bent plate. The two perpendicular sides of the arc-shaped connecting plate 3 are respectively fixedly connected to the second group of displacement slides and the arc welding gun angle adjustment mechanism by screws. The other end of the arc welding gun angle adjustment mechanism 5 is connected to the arc welding gun clamp 4.

[0044] Specifically, the arc welding gun angle adjustment mechanism 5 includes an arc welding plate 51, a welding gun rear connecting plate 52 and a gun pressing plate 53. The arc welding plate 51 is used to connect with the laser welding gun fixture, and the welding gun rear connecting plate is used to connect with the arc welding gun fixture. Figure 6 As shown, the rear connecting plate 52 of the welding gun has a groove on its side facing the gun pressure plate. The rear connecting plate 52 of the welding gun is butted against the gun pressure plate 53 and fixedly connected by screws at the upper and lower sides of the groove, forming a limit slot for the arc welding plate to pass through. The arc welding plate 51 passes through this limit slot and can slide along the limit slot to adjust the relative angle between the laser welding gun fixture and the arc welding gun fixture. The gun pressure plate 53 has several threaded holes in its center. After adjusting the angle, the arc welding plate 51 is tightened by tightening bolts through these threaded holes, thereby fixing the arc welding plate 51 between the gun pressure plate 53 and the rear connecting plate 52 of the welding gun, thereby clamping it.

[0045] Combine Figure 1 、 2As shown, the arc welding plate 51 is fixedly connected to the arc-shaped connecting plate 3 by screws, thereby realizing the connection and fixation of the arc welding gun angle adjustment mechanism and the laser welding gun fixture. A third set of displacement slides is provided on the back of the welding gun rear connecting plate 52. The slide base plate and mounting plate of the third set of displacement slides are respectively connected to the arc welding gun angle adjustment mechanism and the arc welding gun fixture, which can drive the arc welding gun fixture to move linearly in the third direction, thereby adjusting the relative distance between the laser welding gun fixture and the arc welding gun fixture in the third direction. The third direction has an angle with the first direction and the second direction mentioned above. Among them, the slide base plate 13 of the displacement slide is fixedly connected to the welding gun rear connecting plate 52 by screws, realizing the connection and fixation of the arc welding gun angle adjustment mechanism and the arc welding gun fixture.

[0046] Specifically, the arc welding gun fixture 4 includes a welding gun mounting top plate 42 for connecting the arc welding gun, a welding gun mounting bottom plate 41 is fixedly mounted on the bottom of the welding gun mounting top plate 42 by screws, and a first welding gun rib plate 43 and a second welding gun rib plate 44 are respectively mounted on the side and opposite side of the welding gun mounting bottom plate 41. Figure 5 As shown, both sides of the first welding gun rib 43 are screwed to the welding gun mounting bottom plate 41 and the second welding gun rib 44 respectively, and the tops of the first welding gun rib 43 and the second welding gun rib 44 are fixed to the welding gun mounting top plate 42 by screws.

[0047] like Figure 2 As shown, with the arc welding gun fixture, the arc welding gun 8 is installed on the welding gun mounting top plate 42 by screw connection, and the second welding gun rib plate 44 presses the arc welding gun 8 to limit its position, thereby realizing the positioning and installation of the arc welding gun 8.

[0048] Combine Figure 1 As shown, the welding gun mounting base plate and the mounting plate of the third displacement slide are fixedly connected by screws, thereby installing the arc welding gun fixture and the third displacement slide, and then connecting with the arc welding gun angle adjustment mechanism.

[0049] In this embodiment, the relative distance adjustment between the laser welding gun fixture and the arc welding gun fixture in the first, second and third directions is achieved by installing three sets of displacement slides, and the relative angle adjustment between the laser welding gun fixture and the arc welding gun fixture is achieved through the arc welding gun fixture, which can effectively improve the accuracy of positioning and adjustment between the laser welding gun and the arc welding gun, accurately control the distance and angle between the laser welding gun and the arc welding gun, thereby improving the welding quality.
