Description

Technical Field

[0001] The utility model belongs to the technical field of welding auxiliary equipment, and in particular relates to a laser welding auxiliary tool. Background Art

[0002] Laser welding uses a high-energy-density laser beam as a heat source. The beam is focused on the surface or interior of the material to be welded through a focusing lens, forming a small heat source area, causing the material to melt or vaporize rapidly, thereby forming a molten pool or keyhole. Laser welding can be applied to the welding of a variety of materials, including metals and non-metals. When workers use laser welding equipment to weld parts, they often need to use auxiliary tooling to clamp and fix the parts to be welded, so as to ensure stability during welding and improve welding quality.

[0003] However, there are some problems with the existing technology: although the existing auxiliary tooling can achieve the effect of clamping and fixing parts, in actual use, workers often need to weld at multiple positions where two parts are connected, so they need to flip the parts over and continue welding. However, the existing auxiliary tooling is inconvenient to flip the parts over, and the workers need to release the clamping of the parts, manually flip the parts over, and then re-clamp and fix them, which reduces work efficiency. Therefore, we propose a laser welding auxiliary tooling. Utility Model Content

[0008] Optionally, an electric push rod is fixedly installed in the middle of the top of the base, and a cross plate is fixedly connected to the top of the electric push rod.

[0009] Optionally, a through hole is provided on the top of the transverse plate, and movable blocks are slidably connected to both sides of the top of the transverse plate, and the movable blocks are connected to the transverse plate via a driving assembly.

[0021] In order to further understand the content, features and effects of the present invention, the following embodiments are given as examples and described in detail with reference to the accompanying drawings.

[0022] like Figures 1 to 5 As shown, an embodiment of the present invention provides a laser welding auxiliary tooling, comprising a base 1, with frames 2 fixedly mounted on both sides of the top of the base 1, a clamping plate 3 fixedly mounted on the frame 2, a circular ring 4 rotatably connected to the clamping plate 3, a clamping assembly provided inside the circular ring 4, and the circular ring 4 and the base 1 are connected via a flipping mechanism.

[0023] Furthermore, the clamping assembly includes a cylinder 9, which is fixedly mounted on the top of the inner wall of the ring 4. The telescopic end of the cylinder 9 is fixedly connected to a pressure plate 10, and the bottom of the inner wall of the ring 4 is fixedly mounted with a support 11.

[0024] By activating the cylinder 9, the pressing plate 10 can be moved close to the pillar 11, so that the components placed on the pillar 11 can be clamped and fixed, thereby ensuring the stability of the components during welding.

[0025] Furthermore, the flipping mechanism includes a brake motor 5, which is fixedly installed on the left side of the top of the base 1. The output shaft of the brake motor 5 is fixedly sleeved with a rotating shaft 6, and gears 7 are fixedly sleeved on both sides of the outer surface of the rotating shaft 6. The outer surface of the ring 4 is fixedly sleeved with a gear ring 8, and the gear ring 8 is meshingly connected with the gear 7.

[0026] By starting the brake motor 5, the rotating shaft 6 can drive the gear 7 to rotate, which can make the gear ring 8 drive the ring 4 to rotate, and then drive the parts clamped inside the ring 4 to rotate, so that the parts can be flipped to a suitable angle and then continue welding work, which is convenient for continuous welding of different surfaces of the parts, thereby improving work efficiency.

[0027] Furthermore, an electric push rod 12 is fixedly installed in the middle of the top of the base 1, and a horizontal plate 13 is fixedly connected to the top of the electric push rod 12.

[0028] The design of the horizontal plate 13 can support the welding ends of the components, thereby making it easier for workers to place and connect the two components before welding them.

[0029] Furthermore, a through hole 14 is provided on the top of the transverse plate 13 , and movable blocks 15 are slidably connected to both sides of the top of the transverse plate 13 , and the movable blocks 15 are connected to the transverse plate 13 via a driving assembly.

[0030] Furthermore, the drive assembly includes a drive motor 16, which is fixedly mounted on the bottom of the horizontal plate 13. The output shaft of the drive motor 16 is fixedly sleeved with a bidirectional screw rod 17, and both sides of the outer surface of the bidirectional screw rod 17 are threadedly sleeved with sliders 18. The top of the slider 18 passes through the through hole 14 and is fixedly connected to the bottom of the movable block 15.

[0031] By starting the drive motor 16 to rotate the bidirectional screw rod 17, the two sliders 18 can drive the two movable blocks 15 to move toward each other, thereby aligning the two parts to be welded, thereby improving the welding quality.

[0032] Furthermore, there are two electric push rods 12 , and the two electric push rods 12 are symmetrically arranged.

[0033] Working principle: When in use, the staff places the two parts to be welded on the two pillars 11 respectively, so that the positions of the two parts to be welded are docked, and then starts the drive motor 16 to rotate the bidirectional screw 17, so that the two movable blocks 15 can move toward each other to align the two parts to be welded. After alignment, start the cylinder 9 to move the pressure plate 10 downward to clamp the parts, and then start the drive motor 16 to make the two movable blocks 15 move away from each other, and then start the electric push rod 12 to move the cross plate 13 downward, and then the laser welding equipment can be used for welding. When it is necessary to weld other surface positions of the connection between the two parts, the staff can start the brake motor 5 to make the rotating shaft 6 drive the gear 7 to rotate, so that the gear ring 8 can drive the ring 4 to rotate, and then drive the clamped parts to rotate, and the parts can be rotated to the appropriate angle to continue welding work without the need to re-fix the parts, thereby improving work efficiency.
