[0024] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0025] Reference Figure 1-5 The utility model provides an embodiment: a laser welding head that is easy to replace, including a mounting seat 1, which is installed on the work station through the threaded holes on the mounting plates on both sides of the mounting seat 1 and the bolts, and then the equipment circuit is connected to enable the laser welding head 3 to operate normally. The left side of the inner wall of the mounting seat 1 is rotatably connected to the rotating rod 8 and passes through the upper and lower sides. The lower side of the outer wall of the rotating rod 8 is fixedly connected to a transfer block 7. The top of the mounting seat 1 is fixedly connected to the right side of the rotating rod 8, and the bottom end of the worm gear 9 is fixedly connected to the top of the rotating rod 8, and the bottom end of the rotating rod 8 is rotatably connected to the inner wall of the mounting seat 1.

[0026] The inner wall at the rear end of the concave frame 4 is rotatably connected to a worm 6 and a first motor 5 fixedly connected at the front end of the concave frame 4. The front end of the worm 6 penetrates the inner wall of the concave frame 4 and is fixedly connected to the driving end of the first motor 5. The left side of the outer wall of the worm 6 is meshed and connected to the right end of the outer diameter of the worm wheel 9. Starting the first motor 5 rotates the worm 6, and under the transmission of the worm 6, the worm wheel 9 drives the rotating rod 8 to rotate, and then the rotating rod 8 drives the adapter block 7 to adjust the angular position of the laser welding head 3 in the opening range of the mounting seat 1 together with the movable seat 2, thereby expanding the position activity range of the laser welding head 3 for easy operation.

[0027] The right end of the adapter block 7 is fixedly connected to the movable seat 2, and the bottom of the inner wall of the movable seat 2 is fixedly connected to the second motor 10. The left side of the inner wall of the movable seat 2 is rotatably connected to the threaded rod 11, the bottom end of the threaded rod 11 is fixedly connected to the driving end of the second motor 10, and the outer wall of the threaded rod 11 is threadedly connected to the lifting seat 12. The outer wall of the lifting seat 12 is slidably connected to the inner wall of the movable seat 2. Starting the second motor 10 makes the threaded rod 11 rotate and then makes the lifting seat 12 slide up and down in the movable seat 2, thereby making a certain adjustment to the relative height of the laser welding head 3.

[0028] One end of the electric push rod 15 is fixedly connected to the inner walls of the front and rear sides of the right end of the lifting seat 12, and the output ends of the electric push rod 15 are fixedly connected with positioning blocks 16. A T-shaped block 13 is embedded in the inner wall of the left side of the lifting seat 12. The inner walls of the front and rear sides of the left end of the T-shaped block 13 are provided with limiting grooves 14. The other end of the T-shaped block 13 is fixedly connected with the laser welding head 3. The shape of the left end of the positioning block 16 is consistent with the shape of the inner wall of the limiting groove 14. When disassembling the laser welding head 3, it is only necessary to start the electric push rods 15 on both sides to drive the positioning block 16 to move to the right and disengage from the limiting groove 14, so that the T-shaped block 13 loses its restriction, and then the T-shaped block 13 is taken out from the lifting seat 12 together with the laser welding head 3, so as to facilitate the replacement of the laser welding head 3.

[0029] Working principle: First, the mounting base 1 is mounted on the workstation through the threaded holes on the mounting plates on both sides of the mounting base 1 with the bolts, and then the equipment circuit is connected to enable the laser welding head 3 to operate normally. During use, the second motor 10 and the first motor 5 can be started respectively to adjust the position of the laser welding head 3. Starting the second motor 10 makes the threaded rod 11 rotate, thereby making the lifting base 12 slide up and down in the movable base 2, so as to make a certain adjustment to the relative height of the laser welding head 3. Starting the first motor 5 makes the worm 6 rotate, and under the transmission of the worm 6, the worm 6 is driven to move. The wheel 9 drives the rotating rod 8 to rotate, and then the rotating rod 8 drives the adapter block 7 to adjust the angle position of the laser welding head 3 together with the movable seat 2 in the opening range of the mounting seat 1, thereby expanding the position activity range of the laser welding head 3 for easy operation. Later, when disassembling the laser welding head 3, it is only necessary to start the electric push rods 15 on both sides to drive the positioning block 16 to move to the right and disengage from the limit groove 14, so that the T-shaped block 13 loses its restriction, and then the T-shaped block 13 is taken out from the lifting seat 12 together with the laser welding head 3, so as to facilitate the replacement of the laser welding head 3.
