Description

Technical Field

[0001] The utility model relates to the technical field of optical fiber laser welding, in particular to an optical fiber laser welding machine with workpiece clamping. Background Art

[0002] Fiber-optic transmission laser welding machine is a kind of laser welding equipment that couples high-energy laser beam into optical fiber, transmits it over a long distance, collimates it into parallel light through a collimator, and then focuses it on the workpiece for welding. For parts that are difficult to access for welding, flexible transmission non-contact welding is performed, which has greater flexibility. The laser beam of the fiber-optic transmission laser welding machine can achieve time and energy splitting, and can perform multi-beam processing simultaneously, providing conditions for more precise welding.

[0003] The workbench of the traditional fiber laser welding machine is not equipped with a workpiece clamping device, which can easily cause problems in workpiece welding and affect the quality of welding.

[0004] For example, Chinese patent CN213888743U discloses a fiber laser welding machine with a workpiece clamp. The fiber laser welding machine with a workpiece clamp can stably clamp the workpiece on the workbench, and can clamp workpieces of different heights. The height of the workbench can also be adjusted as needed, and the height adjustment and workpiece clamping are very convenient, making it more convenient for users to perform welding operations.

[0005] However, the outer end of the welding machine is not provided with a protective mechanism, so that during the welding process, sparks fly everywhere and easily cause harm to nearby workers.

[0006] For this reason, we urgently need to provide a fiber laser welding machine with a protective structure and workpiece clamping. Utility Model Content

[0010] A further improvement is that limiting holes are provided at the front and rear ends of the moving block, and the outer side of the limiting rod is slidably connected to the inner side of the limiting hole, so that when the moving block moves, it can only slide along the outer side of the limiting rod.

[0011] A further improvement is that a first threaded hole is opened in the middle position inside the moving block, the outer side of the first threaded rod is threadedly connected to the inner side of the first threaded hole, and the right end of the first threaded rod is fixedly connected to the left end of the output shaft of the motor, so that when the motor is started and its output shaft rotates to drive the first threaded rod to rotate, the outer moving block can be driven to move along the outer side of the limit rod.

[0015] A further improvement is that the middle position of the left and right ends of the lower side of the support plate is fixedly connected to the upper end of the output shaft of the cylinder, so that when the cylinder is started and its output shaft moves, the upper support plate can be driven to move, so that workpieces at different heights above the support plate can be moved to the lower end of the welding head for welding.

[0016] In summary, the present application discloses a fiber laser welding machine with workpiece clamping.

[0017] According to the technical solution, during welding, due to gravity, the sealing plate will rotate around the circular axis to be vertically downward and contact the front side of the shell, thereby sealing the front end of the shell and preventing sparks flying during welding from harming the workers, thereby playing a protective role.
