Description

Technical Field

[0001] The utility model relates to the technical field of rail vehicle structural component welding, in particular to a rail vehicle aluminum alloy structural component welding device. Background Art

[0002] In the rail vehicle manufacturing process, multiple aluminum alloy structural parts need to be connected into a whole. Through welding, aluminum alloy structural parts of different shapes and sizes can be firmly connected together to form a complete vehicle structure.

[0003] CN221435307U discloses a welding device for aluminum alloy structural parts with a corrective structure. The device uses a clamping cylinder installed on a mounting plate to drive a clamping mechanism to clamp and secure the aluminum alloy part, preventing it from shifting during welding. A rodless cylinder on the mounting block drives an adjustable electric cylinder for horizontal movement, facilitating welding at different positions. The adjustable electric cylinder drives a laser welding head for vertical movement, moving the laser welding head to the welding position of the aluminum alloy part, thereby welding the aluminum alloy part. The light generated during welding is relatively glaring and can easily cause damage to the eyes. The smoke generated during the laser process is also quite pungent and can cause certain damage to the human body. Utility Model Content

[0028] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings.

[0029] The embodiment of the utility model discloses a welding device for aluminum alloy structural parts of a rail vehicle.

[0030] Example 1

[0031] The utility model provides Figure 1-5 The illustrated welding device for aluminum alloy structural parts of rail vehicles comprises a welding base 1, a support plate 2 is fixedly provided on the top of the welding base 1, and a welding head assembly 3 is fixedly provided on the upper end of the support plate 2;

[0032] The upper end of the interior of the welding base 1 is rotatably penetrated by two symmetrically arranged rotating rods 4, and the two ends of the rod wall of the rotating rod 4 are fixedly sleeved with a light shield 5, which is a brown transparent plastic cover. The lower end of the light shield 5 is provided with a rotating groove 21 provided with the welding base 1, and the lower ends of the two light shields 5 are jointly provided with a welding light shielding mechanism for driving the light shield 5 to move;

[0033] A connecting pipe 6 is fixedly provided on the side of the light-blocking cover 5, and a filter tube 7 is sleeved on one end of the connecting pipe 6. An activated carbon purification layer 8 is fixedly embedded in the interior of the filter tube 7. The pipe mouth of the connecting pipe 6 is connected to a guide pipe 9, and the guide pipe 9 is a corrugated guide pipe. An air pump 10 is fixedly provided on the upper end of the outer wall of the welding base 1, and the lower end of the guide pipe 9 is connected to the air pump 10. An air collecting hood 16 is fixedly sleeved on the end of the connecting pipe 6 away from the guide pipe 9.

[0034] Before welding the aluminum alloy structural parts of rail vehicles, the structural parts are placed on the top of the welding base 1, and the two light shields 5 are rotated and closed to cover the top of the welding base 1 through the rotation support of the rotating rod 4. At this time, the welding head assembly 3 can be controlled to quickly weld the structural parts. Since the light shield 5 is a brown transparent plastic cover, it can absorb and block the glare generated during the welding process. At the same time, the air pump 10 is started before welding. The smoke generated during the welding process can be sucked out through the guide pipe 9 and the connecting pipe 6, and the pungent smoke can be purified through the activated carbon purification layer 8 inside the filter tube 7, thereby reducing the generation of pollutants and ensuring that the operator's body is not injured during the welding process.

[0035] Example 2

[0036] In order to enable the two light shields 5 to rotate and close at the same time, the embodiment 2 is based on the embodiment 1. Figure 1 and Figure 4 As shown, the welding light-blocking mechanism includes a bidirectional screw rod 11, a groove is provided at the lower end of the outer wall of the welding base 1, and the bidirectional screw rod 11 is rotatably arranged in the groove. Both ends of the rod wall of the bidirectional screw rod 11 are threadedly sleeved with sliders 12, and the outer walls of the slider 12 and the light-blocking cover 5 are fixed with connecting rods 13. The rod walls of two adjacent connecting rods 13 are rotatably sleeved with connecting plates 14, and the two adjacent connecting plates 14 are cross-arranged. A placement groove is provided on the outer wall of the welding base 1, and a motor 15 is fixed in the placement groove. The end of the bidirectional screw rod 11 passes through the placement groove and is fixedly connected to the output shaft of the motor 15.

[0037] After the structural part is placed on the top of the welding base 1, the motor 15 is started to rotate the bidirectional screw 11. At this time, the two sliders 12 move away from each other, and under the pull of the connecting plate 14, and in conjunction with the relative rotation of the connecting plate 14 and the connecting rod 13, the light shield 5 can rotate under the rotation support of the rotating rod 5, and finally the two light shields 5 are closed, thereby completing the blocking of light during the welding process.

[0038] Example 3

[0039] Example 3 is based on Example 1 in order to be able to regularly replace the activated carbon purification layer 8 inside the filter tube 7 to ensure timely and effective treatment of the smoke generated during the welding process, such as Figure 1-3 and Figure 5 As shown, the tube wall of the filter tube 7 is provided with a card slot 17, the tube wall of the connecting tube 6 is provided with a movable groove, a vertical rod 18 is fixedly provided inside the movable groove, the rod wall sliding sleeve of the vertical rod 18 is provided with a card block 19, the end of the card block 19 is card-connected in the card slot 17, the card block 19 is L-shaped, and the upper end of the side away from the movable groove is inclined, the rod wall sleeve of the vertical rod 18 is provided with a spring 20, and the two ends of the spring 20 are fixedly connected to the vertical rod 18 and the card block 19 respectively.

[0040] After the filter tube 7 has been used for a long time, the block 19 can be pressed to make the block 19 slide along the vertical rod 18 and stretch the spring 20. At this time, the block 19 is separated from the card slot 17, and the filter tube 7 can be removed and the internal activated carbon purification layer 8 can be taken out and replaced. After the internal components of the filter tube 7 are replaced, the filter tube 7 is directly sleeved on the outside of the connecting tube 6. By squeezing the inclined surface of the block 19, the block 19 can be moved and the elastic force of the spring 20 can be restored to quickly rebound and inserted into the card slot 17, thereby completing the position fixation of the filter tube 7 and ensuring the stable progress of the welding work.
