Detailed Implementation

[0020] 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.

[0021] Please see Figures 1 to 4 This embodiment provides a laser welding machine welding head structure that is easy to disassemble and replace, including a fixing plate 1, a connecting plate 2, a laser head 3, and a connecting component 4. The fixing plate 1 is used to connect with other structures of the laser welding machine, the connecting plate 2 is used to connect the laser head 3, the laser head 3 generates laser to cut the material, and the connecting component 4 is used to connect the connecting plate 2 and the fixing plate 1.

[0022] One side of the connecting plate 2 connects to the laser head 3, and the other side abuts against the fixing plate 1. The connecting plate 2 and the laser head 3 are connected by multiple fixing bolts pressing against the periphery of the laser head 3. This facilitates adjustment of the laser head 3's position relative to the connecting plate 2. To ensure the laser beam position remains unchanged after replacing the laser head 3, the fixing bolts are generally adjusted to center the laser beam of the laser head 3 on the connecting plate 2. Afterward, each replacement only requires ensuring the connecting plate 2 remains in the same position relative to the fixing plate 1. Specifically, this easily disassembled and replaceable laser welding head structure also includes multiple positioning pins 5. The positioning pins 5 are fixedly connected to the side of the connecting plate 2 closest to the fixing plate 1, with the connection direction perpendicular to the surface of the connecting plate 2. The fixing plate 1 has mating holes 1a, and the positioning pins 5 are clearance-fitted into the mating holes 1a, ensuring the connection between the connecting plate 2 and the fixing plate 1 remains consistent after replacement. To ensure consistent relative positions, before use, each laser head 3 must be equipped with a corresponding connecting plate 2 to form a set. The relative positions of the laser head 3 and connecting plate 2 in different combinations of laser head 3 and connecting plate 2 should be adjusted so that the relative positions of the connecting plate 2 and laser head 3 are consistent in a set. More specifically, the relative positions of the laser head 3 and the positioning pin 5 should be consistent. Afterward, each time the laser head 3 is replaced, the original laser head 3 along with the connecting plate 2 is removed and replaced with a new laser head 3 with the connecting plate 2. Only one adjustment is needed when connecting the connecting plate 2 and the laser head 3. When replacing the laser head 3, the positioning pin 5 of the connecting plate 2 is directly engaged with the mating hole 1a. This is to adapt to different specifications of laser head 3 and provide a fixture with consistent interchangeability.

[0023] The connecting assembly 4 includes a rotating handle 4a and a connecting block 4b. The rotating handle 4a is rotatably connected to the connecting plate 2, and the connecting block 4b is fixedly connected to the fixing plate 1. The connecting block 4b has a fixing groove in a direction intersecting the surface of the fixing plate 1. The rotating handle 4a can rotatably switch between sliding into the fixing groove or separating from the fixing groove. Preferably, the connecting assembly 4 also includes a connecting post 4c, which is fixedly connected to the connecting plate 2. The rotating handle 4a includes a rotating part 4aa and an abutting part 4ab. The rotating part 4aa has a through hole and is slidably connected to the connecting post 4c. The abutting part 4ab is fixedly connected to the rotating part 4aa. The rotating part 4aa can rotate to drive the abutting part 4ab to rotate and slide into the fixing groove. At this time, the abutting part 4ab is pressured by the fixing groove to fix the connecting plate 2 to one side of the fixing plate 1. More specifically, the connecting post 4c is arranged in a direction perpendicular to the plane of the connecting plate 2. Preferably, the connecting assembly 4 further includes a compression spring 4d, which is sleeved on the connecting post 4c and abuts against the connecting plate 2 and the rotating part 4aa at both ends, respectively. The function of the compression spring 4d is to reduce the torque on the rotating handle 4a. Most of the force is absorbed by the compression spring 4d, thereby fixing the connecting plate 2 to one side of the fixing plate 1. The laser welding machine may vibrate during operation. In order to ensure that the laser head 3 does not wobble due to vibration during operation after assembly, the compression spring 4d is generally selected with high rigidity, depending on the working environment. Preferably, the rotating handle 4a also includes a gripping part 4ac, which is fixedly connected to the side of the rotating part 4aa away from the abutting part 4ab, making it convenient for the user to grip and rotate the rotating handle 4a. Preferably, multiple connecting assemblies 4 are arranged around the connecting plate 2, respectively fixing the connecting plate 2 around the perimeter of the connecting plate 2.

[0024] Specifically, the fixing slot has a first slot 4ba and a second slot 4bb. The first slot 4ba is parallel to the surface of the fixing plate 1. The second slot 4bb is trumpet-shaped, with one end connected to the first slot 4ba and the other end open. The width of the opening is greater than the width of the connection with the first slot 4ba. The rotating handle 4a can slide into the first slot 4ba along the second slot 4bb. The trumpet design is to facilitate the sliding of the abutment part 4ab into the second slot 4bb. During the process of the abutment part 4ab sliding into the first slot 4ba along the second slot 4bb, it will move closer to the fixing plate 1 due to the pressure of the edge of the second slot 4bb. The pressure spring 4d is compressed and the elastic force increases. After sliding into the first slot 4ba, the compression of the pressure spring 4d is at its maximum. At this time, the connecting plate 2 can be pressed tightly onto the fixing plate 1 to achieve fixation. Preferably, a limiting boss 4bc is formed at the connection between the first slot 4ba and the second slot 4bb. The limiting boss 4bc is formed along the direction close to the fixing plate 1. The function of the limiting boss 4bc is to prevent the abutment part 4ab from accidentally sliding out after sliding into the first slot 4ba.

[0025] In summary, this utility model provides a laser welding machine welding head structure that is easy to disassemble and replace. The laser head 3 is used in conjunction with the connecting plate 2. When replacing the laser head 3, it is only necessary to remove the connecting plate 2 from the fixing plate 1 and then replace the connecting plate 2 with the new laser head 3. The connecting plate 2 and the fixing plate 1 are fixed by a rotating handle 4a and a connecting block 4b. Rotating the rotating handle 4a can fix or separate the connecting plate 2. The entire disassembly and assembly process is very simple and time-saving.
