Description

Technical Field

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

[0002] Spatter during laser welding can have a multifaceted impact on the welding process and weld quality. Spatter refers to droplets of molten metal ejected from the melting point during welding. These droplets can land on surrounding surfaces, causing rough and uneven surfaces. Laser welding spatter can cause numerous problems, including light pollution, an untidy work environment, and a disruption to personnel. Spatter that lands on welding equipment can corrode and damage its mechanisms over time. High-heat particles that land on surrounding objects can cause burns. When laser welding alloy antenna frames, a protective shield can be used to contain laser welding spatter. However, this shielding causes the sealed welding environment to heat up, necessitating effective ventilation and cooling. The frame has many branches, and after welding each branch, the welded portion must cool and harden before the frame can be moved. This prevents vibration and loosening caused by moving the welded portion before it is firmly hardened. Cooling or ventilation can be applied to the welded portion to accelerate cooling and hardening. To this end, the present invention provides equipment for welding alloy antenna frames.

The C-type rail body 12 is meshed with the first gear 27 through arc-shaped convex teeth for transmission. 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.

[0062] 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 shunt gear 32 fixed at one end of the sub-shaft 34, and an activating prism 35 fixed at the other end of the sub-shaft 34.

One end of the J-shaped spring piece 281 is fixed to the multi-control frame 24, and the other end is pressed on the L-shaped sub-frame 33. The sub-shaft 34 is movably sleeved in the through hole opened in the L-shaped sub-frame 33.

[0063] The speed increasing group 29 includes a U-shaped frame 39 fixed on the multi-control frame 24, a prism 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 36, and a ring plate gear 38 fixed on the outside of the one-way bearing 37, which drives the prism 35 to slide into the prism hole opened in the middle of the prism 36.

[0064] 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 to 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.

[0065] 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 rotation of the entire protective half shell 7 and the laser emitter 8. While rotating, the laser emitter 8 of the prior art emits a laser, and the laser is shot at the contact part 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, accelerating local cooling and hardening.

[0066] The 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 compresses the elastic curved rod 30, and then the elastic curved rod 30 drives the L-shaped sub-frame 33 to translate, and then the sub-shaft 34 drives the branch gear 32 to move axially, and the branch gear 32 and the first gear 27 contact and mesh. In this way, the rotation of the first gear 27 will also transmit the branch gear 32, and then the sub-shaft 34 drives the prism 35 to rotate. Next, 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 hole on the disk box 40 is connected to the pipeline of the cold air supply mechanism, or it can be connected without a 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 pipe 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.

[0067] After the frame center column 2 and the frame support 3 are welded and cooled, the frame center column 2 drives the frame support 3 to move horizontally, and before that, the first shaft 26 is driven in the reverse direction, and 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 connected to the push-pull mechanism in the prior art. The concave frame 20 moves horizontally to drive the worm 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 moves away to the right.

[0068] While 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 these embodiments without departing from the principles and spirit of the invention, and that the scope of the invention is defined by the appended claims and their equivalents.
