Description

Technical Field

[0001] The invention relates to the technical field of laser welding, in particular to an alloy antenna frame welding device. Background Art

[0002] The spatter in laser welding will have many effects on the welding process and weld quality. Spatter refers to the molten metal droplets ejected from the melting point during the welding process. These droplets will fall on the surface of the surrounding objects, resulting in a rough and uneven surface. The spatter in laser welding will cause many problems. For example, spatter will bring light pollution to the surrounding environment, making the working environment untidy and affecting the staff; spatter will fall on the welding instrument, which will corrode and damage the mechanism on the instrument in the long run; the high-temperature particles of spatter fall on the surrounding objects and may cause combustion. When laser welding the alloy antenna frame, a protective cover can be used to cover the spatter of laser welding, but the cover will cause the sealed welding environment to heat up, so effective ventilation and cooling are required. There are many branches on the frame. After welding each branch, it is necessary to wait for the welding part to cool and harden before moving the frame to prevent the vibration and loosening caused by moving the welding part without firm hardening. The welding part can be blown with cold air or ventilation to accelerate the cooling and hardening of the welding part. For this purpose, the present invention provides an alloy antenna frame welding device. Summary of the invention

The fixed pipe 14 and the L-shaped neck tube 23 are fixedly connected.

[0038] The air supply integration 6 includes a multi-control frame 24 fixed on the main board 1, a first shaft 26 supported on the multi-control frame 24, a first gear 27 fixed at one end of the first shaft 26, an adjustment group 28 with one end overlapped with the first gear 27 for transmission, a J-shaped spring 281 for compressing the adjustment group 28 to reset, a bellows 25 connected to the L-shaped neck tube 23, and a speed increase group 29 transmitted between the bellows 25 and the adjustment group 28. The C-type rail body 12 is meshed and connected with the first gear 27 through arc-shaped convex teeth. An elastic curved rod 30 is also provided on the adjustment group 28. The C-type rail body 12 is fixed with a convex arc plate 31 to compress and brake the elastic curved rod 30. The first shaft 26 is movably sleeved in a through hole opened on the multi-control frame 24.

[0039] The adjustment group 28 includes an L-shaped sub-frame 33 that slides through a square hole opened on the multi-control frame 24, a sub-shaft 34 supported on the L-shaped sub-frame 33, a branch gear 32 fixed at one end of the branch shaft 34, and an activating prism 35 fixed at the other end of the branch shaft 34.

The sub-shaft 34 is movably sleeved in the through hole opened on the L-shaped sub-frame 33.

[0040] The speed increasing group 29 includes a U-shaped frame 39 fixed on the multi-control frame 24, a prism tube 36 movably sleeved in a through hole opened at one end of the U-shaped frame 39, a one-way bearing 37 fixed on the outside of the prism tube 36, and a ring plate gear 38 fixed on the outside of the one-way bearing 37, which drives the prism 35 to slide and insert into the prism hole opened in the middle of the prism tube 36.

[0041] The bellows 25 includes a disk box 40 fixed on the multi-control frame 24, a fan 41 distributed in the disk box 40, and a fan shaft 42 fixed in the middle of the fan 41. The fan shaft 42 passes through a through hole opened on the shell of one side of the disk box 40. The fan shaft 42 is movably sleeved in the through hole opened on the U-shaped frame 39, and the end of the fan shaft 42 is meshed and connected with the ring plate gear 38 through a fixed gear. An air inlet is provided on the shell on the other side of the disk box 40, and the L-shaped neck tube 23 is fixedly connected to the disk box 40.

[0042] The first shaft 26 is externally connected to the motor drive mechanism in the prior art. The first shaft 26 drives the first gear 27 to rotate, thereby controlling the rotation of the C-type rail body 12, and then drives the T-plate 9 through the Z-type column 11, thereby controlling the overall rotation of the protective half shell 7 and the laser emitter 8. While rotating, the laser emitter 8 of the prior art emits laser, and the laser is shot at the contact position between the skeleton pillar 3 and the skeleton middle column 2, so that the skeleton middle column 2 and the skeleton pillar 3 are laser welded. The four laser emitters 8 move around the skeleton pillar 3 at the same time. Each laser emitter 8 only needs to circle a quarter of a circle to complete the welding between the skeleton middle column 2 and the skeleton pillar 3. When the laser emitter 8 rotates for welding, cold air cooling work occurs immediately thereafter. In this way, the cold air is blown to the welded part through the small tube 17 to accelerate local cooling and hardening.

[0043] Principle of cold air supply: After the C-shaped rail body 12 rotates a short distance, the convex arc plate 31 fixed on the C-shaped rail body 12 contacts and presses the elastic curved rod 30, and then the elastic curved rod 30 drives the L-shaped frame 33 to translate, and then the branch shaft 34 drives the branch gear 32 to move axially, and the branch gear 32 and the first gear 27 are in contact and meshing. In this way, the rotation of the first gear 27 will also transmit the branch gear 32, and then the branch shaft 34 drives the prism 35 to rotate, and then the prism 36 drives the one-way bearing 37, and then the ring plate gear 38 drives the fan shaft 42, and the fan 41 continues to rotate for ventilation. The air inlet on the disk box 40 is connected to the pipeline of the cold air supply mechanism, or it can be connected without the pipeline, and natural wind ventilation and cooling are adopted. The airflow in the disk box 40 is injected into the L-shaped neck tube 23, and then diffused to each fixed tube 14 through the C-shaped column pipeline 21, and then dispersed to the small tube 17 through the arc unit tube 16. The airflow blown out of the small tube 17 directly impacts the welded part.

[0044] After the frame middle column 2 and the frame support 3 are welded and cooled, the frame middle column 2 drives the frame support 3 to translate, and before that, the first shaft 26 is driven in the reverse direction, so that the welding equipment is restored to the initial state, that is, Figure 2 In the state shown, the two protective half shells 7 need to be separated so that the skeleton support 3 can move to the right and leave. Specifically, the concave frame 20 is externally connected to the push-pull mechanism in the prior art. The concave frame 20 translates to drive the worms 18 at both ends to rotate, thereby driving the T-plate 9 to move. The T-plate 9 drives the laser emitter 8 and the protective half shell 7, so that Figure 2 The two protective half shells 7 in the upper and lower parts are separated, and then the skeleton support 3 is translated to the right and away.

[0045] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
