Detailed Implementation

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] like Figure 1-5 As shown, this utility model provides a technical solution: a laser welding device with a clamping structure, including a processing table 1. Two fixing plates 2 are fixedly connected to the upper end of the processing table 1. Two electric push rods 4 are fixedly connected to the relatively close ends of the two fixing plates 2. The relatively close ends of the four electric push rods 4 are respectively fixedly connected to two clamping adjustment mechanisms 6. The two clamping adjustment mechanisms 6 can respectively achieve the clamping and fixing effect on two parts to be welded. Activating the electric push rods 4 can drive the two clamping adjustment mechanisms 6 to move relative to each other, thereby causing the welding ends of the two parts to be welded to overlap. The welding position of the parts to be welded can be adjusted to be directly below the laser welding head 10. The lower ends of the two clamping adjustment mechanisms 6 are slidably connected to two rotating rods 7, each with two guide sliders. The front and rear sides of the two clamping adjustment mechanisms 6 are slidably connected to two fixing rods 5. The upper ends of the two fixing plates 2 are fixedly connected to a fixing frame 3. Rod 5 increases the stability of the clamping adjustment mechanism 6 during movement. The rotation of the two rotating rods 7, under the action of the two clamping adjustment mechanisms 6, can drive the two clamped parts to be welded to rotate together, thereby facilitating the adjustment of the welding position of the two parts to be welded. This eliminates the need to remove the parts to be welded from the device, flip them over, and then re-clamp them, improving welding efficiency. The fixing frame 3 is movably connected to the front and rear sides of the threaded rod 11 through circular holes at both ends. The threaded rod 11 is threadedly connected to the sliding table 12, which has threaded holes inside. An electric telescopic cylinder 9 is fixedly connected to the lower end of the sliding table 12. A laser welding head 10 is set at the lower end of the electric telescopic cylinder 9. By rotating the threaded rod 11, the sliding table 12 moves in the front and rear direction, and with the cooperation of the electric telescopic cylinder 9, the position of the laser welding head 10 can be adjusted, making it convenient to adjust the position of the laser welding head 10 according to the welding position.

[0026] The relatively close ends of the two rotating rods 7 are fixedly connected to the two output shafts of the dual-axis motor 8, respectively. The relatively far ends of the two rotating rods 7 are movably connected to the two fixed plates 2, each with a circular hole inside. The left and right ends of the two fixed rods 5 are fixedly connected to the relatively close ends of the two fixed plates 2, respectively. The lower end of the dual-axis motor 8 is fixedly connected to the processing table 1. The sliding table 12 is slidably connected to the two fixed rods 13 through the two circular holes inside. The front and rear ends of the two fixed rods 13 are fixedly connected to the front and rear sides inside the fixed frame 3, respectively. The fixed rods 13 can restrict the movement direction of the sliding table 12. The rotation of the output shaft of the dual-axis motor 8 can drive the two rotating rods 7 to rotate.

[0027] Both clamping and adjusting mechanisms 6 include T-shaped plates 61. The relatively distant ends of the two T-shaped plates 61 are fixedly connected to four electric push rods 4. Both T-shaped plates 61 are slidably connected to two fixed rods 5 through two circular holes opened inside their lower ends. Both T-shaped plates 61 are movably connected to two rotating sleeves 62 through connecting holes opened inside their lower ends. Both rotating sleeves 62 are slidably connected to two rotating rods 7, each with two guide slides, through two guide grooves opened inside them. Both rotating sleeves 62 are fixedly connected to bevel gears 63. The two bevel gears 63 mesh with two bevel gears 64, and the two bevel gears 64 mesh with two... Worm gears 65 are fixedly connected, and each worm gear 65 meshes with a worm wheel 68. Each worm wheel 68 is fixedly connected to one end of a shaft 69. The rotation of the two rotating rods 7, under the action of the two rotating sleeves 62, drives the two bevel gears 63 to rotate. The two bevel gears 63 mesh with two bevel gears 64, which, in turn, drive the two shafts 69 to rotate under the action of the worm gears 65 and worm wheels 68. Activating the electric push rod 4 moves the two T-shaped plates 61 closer together, and the T-shaped clamp 610 moves the two parts to be welded closer together until welding begins. The two shafts 69 are joined together and located on the lower side of the laser welding head 10. The other ends of both shafts 69 are fixedly connected to concave frames 67. Each concave frame 67 is movably connected to the upper and lower sides of two threaded rods 611 through two circular holes. Each threaded rod 611 has two T-shaped clamps 610 threadedly connected to it. The four T-shaped clamps 610 are arranged in pairs and movably connected to two fixed rods 612 through circular holes. The upper and lower ends of the two fixed rods 612 are fixedly connected to the upper and lower sides of the two concave frames 67. The two shafts 69 are movably connected to two T-shaped plates 61, each with another connecting hole at its upper end. The two worm gears... L-shaped plates 66 are movably connected to each of the two L-shaped plates 66. The relatively close ends of the two L-shaped plates 66 are respectively fixedly connected to two T-shaped plates 61. By rotating the threaded rod 611, under the action of the fixed rod 612, the corresponding two T-shaped clamping plates 610 can be driven to move closer to each other, thereby achieving the clamping and fixing effect of the two parts to be welded. By rotating the two rotating shafts 69, the two concave frames 67 can be driven to rotate, and under the action of the T-shaped clamping plates 610, the two clamped parts to be welded can be driven to rotate together, thereby achieving the adjustment of the welding position of the two parts to be welded, facilitating the welding treatment of different surfaces of the two parts to be welded, and improving the welding efficiency.

[0028] The operation steps of this utility model are as follows:

[0029] Two parts to be welded are placed between corresponding T-shaped clamps 610. Then, by rotating the two threaded rods 611, the two T-shaped clamps 610 are brought closer together, thus clamping and fixing the two parts. After clamping and fixing, four electric push rods 4 are activated to bring the two T-shaped plates 610 closer together, thereby bringing the two parts to be welded closer together until their welding ends overlap and are located at the lower end of the laser welding head 10. Then, by activating the electric telescopic cylinder 9, the laser welding head 10 is moved downwards to a suitable position, thus achieving the desired welding effect. During the welding process, when it is necessary to flip the two parts to be welded, the dual-axis motor 8 is started to drive the two rotating rods 7 to rotate. Then, under the action of the set rotating sleeve 62, bevel gear 1 63, bevel gear 2 64, worm 65 and worm wheel 68, the two rotating shafts 69 are driven to rotate. Through the rotation of the two rotating shafts 69, under the action of the set concave frame 67, threaded rod 2 611 and T-shaped clamp 610, the two clamped parts to be welded can be driven to rotate together, thereby achieving the flipping process of the two parts to be welded, which facilitates welding at different positions of the two parts to be welded.
