Description

Technical Field

[0001] This utility model relates to the field of laser welding technology, and in particular to a laser cutting and welding device. Background Technology

[0002] Laser cutting and welding equipment is a device that integrates laser cutting and laser welding functions, playing a vital role in industrial manufacturing. Laser cutting uses a high-energy-density laser beam to locally heat materials, melting or vaporizing them to achieve cutting. Precise control of the laser beam during this process results in smooth cutting edges, a small heat-affected zone, and high cutting speed. Laser welding also utilizes a high-energy-density laser beam to locally heat materials, melting them and joining them. Laser welding is characterized by high precision, a small heat-affected zone, high-speed welding, and strong adaptability.

[0003] Chinese Patent Publication No. CN218695165U discloses a laser cutting and welding device, including a worktable. Several support columns are fixedly connected to the bottom surface of the worktable. A welding frame is sleeved on the outside of the worktable. A transverse welding adjustment component is provided on the upper surface of the welding frame. A longitudinal welding adjustment component is provided on the inner bottom of the welding frame. A first frame is fixedly connected to the rear side of the upper surface of the worktable. A second frame is fixedly connected to the front side of the upper surface of the worktable. A support frame is fixedly connected inside the second frame. In use, the position of the laser head can be flexibly adjusted by cooperating with the transverse welding adjustment component and the longitudinal welding adjustment component.

[0004] Although the equipment described in the aforementioned literature can perform cutting or welding using a laser head, the laser head cannot be replaced, and the same device cannot complete both cutting and welding processes. Typically, in laser cutting and welding equipment, cutting and welding do not use the same laser head. The laser parameters required for cutting and welding, such as power, focal length, and spot size, differ significantly, making it difficult to meet these requirements simultaneously with a single laser head. Therefore, the functionality of the aforementioned device is limited. Furthermore, the aforementioned device can only move in horizontal and vertical directions and cannot cut along an arc trajectory, which limits the processing range and affects processing accuracy. Utility Model Content

[0005] The main purpose of this invention is to provide a laser cutting and welding device that can effectively solve the problems of not being able to replace the laser head and not being able to cut along an arc trajectory.

[0024] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0025] Example 1

[0026] like Figure 1 and Figure 2As shown, a laser cutting and welding device includes an operating table 1. Slide rails 2 are fixedly connected to both sides of the upper end of the operating table 1. A support 3 is slidably connected to the upper side of both slide rails 2. A slide rail 4 is fixedly connected to the lower end of the support 3. A slider 5 is slidably connected to the lower side of the slide rail 4. A rotating component 6 is fixedly connected to the lower end of the slider 5. A moving component 7 is fixedly connected to the lower side of the rotating component 6. A fixing component 8 is fixedly connected to the lower side of the moving component 7. A laser head 9 is movably connected to the lower side of the inner surface of the fixing component 8.

[0027] In the specific implementation process of this embodiment, the workpiece to be cut and welded is placed on the upper end of the operating table 1 and fixed by the fixing structure, and then the position of the laser head 9 is roughly adjusted by the slide rail 1 2 and the slide rail 2 4.

[0028] like Figure 3 As shown, the rotating assembly 6 includes a support 61 fixedly connected to the lower end of the slider 5. A rotating shaft 62 is rotatably connected to the middle of the support 61. A gear 63 is fixedly connected to the middle of the outer surface of the rotating shaft 62. A gear 64 is rotatably connected to one side of the lower end of the support 61. The gear 63 and the gear 64 mesh with each other. A gear 65 is rotatably connected to the lower side of the outer surface of the rotating shaft 62. A clutch gear set 66 is rotatably connected to the other side of the lower end of the support 61. Two motors 67 are fixedly connected to the upper side of the support 61. The output ends of the two motors 67 pass through the support 61 and are fixedly connected to the gear 64 and the clutch gear set 66 respectively through couplings.

[0029] like Figure 4 As shown, the moving component 7 includes a second support 71 fixedly connected to the lower end of the rotating shaft 62. Two guide rods 72 are fixedly connected to the lower side of the inner surface of the second support 71. A sliding plate 73 is slidably connected to the outer surface of the two guide rods 72. A threaded rod 74 is rotatably connected to the upper side of the sliding plate 73. A bevel gear set 75 is fixedly connected to the left end of the threaded rod 74. The upper end of the bevel gear set 75 passes through the second support 71 and is fixedly connected to a fourth gear 76.

[0030] The fourth gear 76 meshes with the third gear 65.

[0031] The clutch gear set 66 adopts existing technology and its working principle is based on the motion principle of gear teeth engaging and disengaging. In the initial state, the teeth of the driving gear and the driven gear are in contact and fully engaged. At this time, the driving gear and the driven gear share the same speed and direction, and force can be transmitted through the gears. When it is necessary to cut off or change the force transmission, the clutch gear will separate the teeth of the driving gear and the driven gear from the engaged state. This is usually achieved through a clutch mechanism. When the clutch gear needs to transmit force again, the teeth of the driving gear and the driven gear will re-engage and gradually engage together.

[0032] The clutch gear set 66 is separated from the third gear 65. A motor 67 fixedly connected to the clutch gear set 66 drives the clutch gear set 66 to rotate. The clutch gear set 66 drives the third gear 65 to rotate, which in turn drives the fourth gear 76 to rotate. The fourth gear 76 drives the bevel gear set 75 and the threaded rod 74 to rotate, thereby moving the sliding plate 73. The sliding plate 73 can drive the fixed component 8 and the laser head 9, thereby achieving precise adjustment of the position of the laser head 9.

[0033] Then, the clutch gear set 66 is separated from the gear three 65. After that, a motor 67 fixedly connected to the gear two 64 drives the gear two 64 to rotate. The gear two 64 drives the gear one 63, the rotating shaft 62 and the moving component 7 to rotate, thereby adjusting the position of the laser head 9 or cutting along an arc trajectory.

[0034] Example 2

[0035] The only difference between this embodiment and Embodiment 1 is that the laser cutting and welding device further includes a fixing component 8, which is used to fix the laser head 9, thereby enabling the rapid replacement of the laser head 9.

[0036] like Figure 5 As shown, the fixing component 8 includes a fixing cover 81 fixedly connected to the lower end of the sliding plate 73. A fixing ring 82 is fixedly connected to the lower end of the fixing cover 81. A plurality of adjustment holes 83 arranged in a ring array are opened on the outer side of the fixing ring 82. A rotating ring 84 is threadedly connected to the lower side of the outer surface of the fixing cover 81. The lower side of the inner surface of the rotating ring 84 is adapted to the shape of the fixing ring 82.

[0037] The fixing ring 82 is a cone that is larger at the top and smaller at the bottom, and the laser head 9 is movably connected to the inner surface of the fixing ring 82.

[0038] In the specific implementation process of this embodiment, after the cutting process is completed, the rotating ring 84 can be rotated to move the rotating ring 84 downward and gradually away from the fixed ring 82, so that the laser head 9 can be taken out from the fixed ring 82. Then, the laser head 9 used for welding is put into the fixed ring 82, and the rotating ring 84 is rotated in the opposite direction to move the rotating ring 84 upward and tighten the fixed ring 82, thereby fixing the laser head 9 used for welding and welding the workpiece.

[0039] The laser parameters required for cutting and welding, such as power, focal length, and spot size, vary greatly, making it difficult to meet these requirements simultaneously with a single laser head. By using the fixed component 8, the cutting head or welding head can be quickly changed according to processing needs, improving the flexibility and applicability of the equipment.

[0040] It should be noted that the specific installation methods, circuit connection methods, and control methods of the slide rail 1 2, slide rail 2 4, and motor 67 used in this utility model are all conventional designs, and will not be described in detail in this utility model.

[0041] The working principle of this utility model is as follows: First, the workpiece to be cut and welded is placed on the upper end of the operating table 1 and fixed by the fixing structure. Then, the position of the laser head 9 is roughly adjusted by the slide rail 1 2 and slide rail 2 4. First, the clutch gear set 66 is separated from the gear 3 65. A motor 67 fixedly connected to the clutch gear set 66 drives the clutch gear set 66 to rotate. The clutch gear set 66 drives the gear 3 65 to rotate, which in turn drives the gear 4 76 to rotate. The gear 4 76 drives the bevel gear set 75 and the threaded rod 74 to rotate, thereby moving the sliding plate 73. The sliding plate 73 can drive the fixing component 8 and the laser head 9, thereby achieving precise adjustment of the position of the laser head 9.

[0042] Then, the clutch gear set 66 is separated from the gear three 65. After that, a motor 67 fixedly connected to the gear two 64 drives the gear two 64 to rotate. The gear two 64 drives the gear one 63, the rotating shaft 62 and the moving component 7 to rotate, thereby adjusting the position of the laser head 9 or cutting along an arc trajectory. After the cutting process is completed, the rotating ring 84 can be rotated to move the rotating ring 84 downward and gradually away from the fixed ring 82, so that the laser head 9 can be removed from the fixed ring 82. Then, the laser head 9 used for welding is put into the fixed ring 82. The rotating ring 84 is rotated in the opposite direction to move the rotating ring 84 upward and tighten the fixed ring 82, thereby fixing the laser head 9 used for welding and welding the workpiece.

[0043] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claims. The scope of protection of this utility model is defined by the appended claims and their equivalents.
