Description

Technical Field

[0001] The present invention relates to the technical field of laser welding, and particularly to an intelligent automatic welding device for the processing of air coolers. Background Art

[0002] Among them, the square tube is a component used for connecting and supporting the housing of the air cooler. In addition, some air coolers are relatively large in size, so it is necessary to weld the square tubes to increase the supporting force for the air cooler.

[0003] For the existing intelligent automatic welding device for the processing of air coolers, there are the following problems: 1. When there are depressions or protrusions in the parts to be welded of two square tubes, if the size of the laser welding spot remains unchanged, it will lead to improper welding and over-welding of the weld seam; 2. Most of the existing spot adjustments control the beam by adjusting the area of the light outlet, but this will not only cause the beam to be blocked but also result in energy loss, and even damage the lens.

[0008] Preferably, socket discs are fixedly connected to both the upper and lower sides of the inner cavity of the end face table. Bearings are fixedly connected inside the socket discs, and the inside of the bearings is in press fit with the threaded rod; The thickness of the socket disc represents the minimum distance between the two square tubes.

[0009] Preferably, an adjusting handle is threadedly connected to the outside of the threaded rod. The number of adjusting handles is two, and they are symmetrically arranged on both sides of the socket disc respectively; The threaded holes inside the two adjusting handles are opened in opposite directions, so that when the threaded rod rotates, the two adjusting handles move in opposite directions.

[0010] Preferably, a telescopic rod is fixedly installed on the outside of the adjusting handle. One end of the telescopic rod away from the adjusting handle is fixedly connected to the end face table; A square sleeve is fixedly installed on the outside of the adjusting handle. Pipe fittings are slidably fitted inside both the adjusting handle and the square sleeve.

[0011] Preferably, the welding mechanism further includes a side rail, which is fixedly installed on the outside of the support table. A slide bar is slidably fitted inside the side rail; The slide bar is driven by an external power device to move inside the side rail, so that the laser welding assembly performs welding treatment on the two square tubes.

[0012] Preferably, a first partition plate is slidably fitted on the top of the pipe fitting. A second partition plate is nested and fitted on the outside of the first partition plate.

[0016] Compared with the prior art, the beneficial effects of the present invention are: 1. Since the thread patterns between the two adjusting handles and the threaded rod are opposite, when the two threaded rods rotate forward, the two adjusting handles will move synchronously in the opposite direction. At the same time, it also plays a role in adjusting the weld between two different pipe fittings.

[0017] 2. The central part of the threaded rod is connected to the socket disc through a bearing, and the socket disc is fixedly connected to the inner side of the end face table. The end face table plays a role in determining the minimum distance of the weld between the two pipe fittings, that is, the width of the end face table is the minimum distance of the weld.

[0018] 3. A first material separating plate is arranged on the top of the pipe fitting, and the first material separating plate is slidably fitted inside the second material separating plate. Therefore, the two play a role in protecting other parts of the pipe fitting that do not need to be welded to avoid damage caused by some molten solder falling on other parts of the pipe fitting.

[0019] 4. Since the contact surfaces between the hyperbolic block and the top inclined block are both inclined surfaces, as the top inclined block moves outwards, the extension plate connected to the hyperbolic block will drive the focusing lens to move downwards. At this time, the light spot of the light beam passing through the focusing lens will gradually become larger, so as to avoid the problem that the light spot is too small to cause improper welding of the sunken part when there is a sunken problem in the part where the pipe fitting needs to be welded.

[0020] 5. When there is a convexity problem at the welding part required for the pipe fitting, the top inclined block will move towards the center and exert an upward extrusion on the hyperbolic block, so that the focusing lens moves upward. At this time, the light spot of the light beam passing through the focusing lens will gradually become smaller, thus playing a role in avoiding over-welding of the convex part due to an overly large light spot when there is a convexity problem at the welding part required for the pipe fitting.

Detailed implementation manners

[0034] Next, in combination with the accompanying drawings and specific implementation manners, the present invention will be further described. It should be noted that, on the premise of no conflict, any combination of the following-described embodiments or technical features can form a new embodiment. It should be known that the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0035] Please refer to Figures 1 to 12 , the present invention provides a technical solution: as Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 shown, it includes a support table 7 for supporting the entire welding equipment. A slide rail 1 is fixedly installed on the top of the support table 7. A slide table 2 is slidably fitted on the top of the slide rail 1. A roller support 3 is fixedly installed on the top of the slide table 2. A toggle piece 4 is slidably fitted inside the roller support 3 through a roller body; By sliding and adjusting the toggle piece 4 on the roller body, the central part of the square tube of the air cooler can be limited; An adjusting mechanism 5 for limiting and distance-adjusting the square tube, and the adjusting mechanism 5 is arranged on the slide rail 1; A welding mechanism 6 for automatically welding the square tube and adjusting the laser beam, and the welding mechanism 6 is arranged on the slide rail 1.

[0036] The adjusting mechanism 5 includes an end face table 51. The end face table 51 is fixedly installed on the outer end face of the slide rail 1. An outer connecting plate 52 is fixedly connected to the outside of the end face table 51. A rotating shaft 54 is rotatably installed on the outside of the outer connecting plate 52; The adjusting handle 53 is used to adjust the rotation of the rotating shaft 54 and the distance between the two square tubes, and is fixedly connected to the rotating shaft 54; One end of the rotating shaft 54 away from the adjusting handle 53 is connected to a gearbox 55. The gearbox 55 is used to transfer the rotational force of the rotating shaft 54 to different positions and heights. One end of the gearbox 55 away from the rotating shaft 54 is connected to a threaded rod 56; One end of the threaded rod 56 away from the gearbox 55 is rotatably installed inside the end face table 51; Both the upper and lower sides of the inner cavity of the end face table 51 are fixedly connected with socket discs 50. The inside of the socket discs 50 is fixedly connected with bearings 59. The inside of the bearings 59 is in press-fit with the threaded rod 56; The thickness of the socket disc 50 represents the minimum distance between the two square tubes; The outside of the threaded rod 56 is threadedly connected with adjusting handles 57. The number of the adjusting handles 57 is two, and they are symmetrically arranged on both sides of the socket disc 50 respectively. The central part of the threaded rod 56 is connected to the socket disc 50 through a bearing 59, and the socket disc 50 is fixedly connected to the inner side of the end face table 51. The end face table 51 is used to determine the minimum distance of the weld between the two pipe fittings 502. That is, the width of the end face table 51 is the minimum distance of the weld.

[0037] The threaded holes inside the two adjusting handles 57 are opened in the reverse direction, so that when the threaded rod 56 rotates, the two adjusting handles 57 move in the reverse direction; The outside of the adjusting handle 57 is fixedly installed with a telescopic rod 58. One end of the telescopic rod 58 away from the adjusting handle 57 is fixedly connected to the end face table 51. One end of the threaded rod 56 away from the gearbox 55 is rotatably installed inside the end face table 51. Therefore, the threaded rod 56 is positioned and rotates without being able to move. In addition, telescopic rods 58 are fixedly installed on the outside of both adjusting handles 57, and the telescopic rods 58 are used to support the adjusting handles 57.

[0038] A square sleeve 501 is fixedly installed on the outer side of the adjusting handle 57, and a pipe fitting 502 is slidably fitted inside both the adjusting handle 57 and the square sleeve 501. By passing the pipe fitting 502 through the adjusting handle 57 and the square sleeve 501 in sequence, and then placing the pipe fitting 502 passing through the former two on the roller body fixedly connected to the inner side of the roller support 3, and finally placing the front end of the pipe fitting 502 on one end of the slide rail 1 close to the welding mechanism 6. After the two pipe fittings 502 are placed, rotate the adjusting handle 53 clockwise, so that the rotating shaft 54 connected to its central part will deflect clockwise accordingly. One end of the rotating shaft 54 is connected to the gearbox 55, and the function of the gearbox 55 is to perform a commutation drive process on the rotational force of the rotating shaft 54. On the other side of the gearbox 55, it is connected to two threaded rods 56. Therefore, the two threaded rods 56 will rotate in the same direction, and the two threaded rods 56 are also threadedly connected to the two adjusting handles 57, but the thread patterns between the two adjusting handles 57 and the threaded rods 56 are opposite, so that when the two threaded rods 56 rotate forward, the two adjusting handles 57 will move synchronously in the opposite direction. At the same time, it also plays a role in adjusting the weld between the two different pipe fittings 502.

[0039] The pipe body 502 is a square pipe used for connecting and supporting the shell of the air cooler. Some air coolers are large in size, so it is necessary to weld the square pipes to increase the supporting force for the air cooler.

[0040] Such as Figure 6 、 Figure 7 、 Figure 8 、 Figure 9 、 Figure 10 、 Figure 11 and Figure 12 As shown in Drive the slide bar 62 to move inside the side rail 61 through an external power device, so that the laser welding assembly 63 performs welding treatment on the two square pipes; The top of the pipe fitting 502 is slidably fitted with a first material separating plate 64. The outside of the first material separating plate 64 is nested and fitted with a second material separating plate 65. One end of the second material separating plate 65 away from the first material separating plate 64 is fixedly connected to the end face table 51. After the distance between two pipe fittings 502 is adjusted, an external power device is used to drive the slide rod 62 to move forward in the side rail 61. The top of the slide rod 62 is connected to the laser welding assembly 63. Therefore, the laser welding assembly 63 will move forward and perform laser welding on the gap between the two pipe fittings 502. The top of the pipe fitting 502 is provided with a first material separating plate 64, and the first material separating plate 64 is slidably fitted in the second material separating plate 65. Therefore, the two play a role in protecting other parts of the pipe fitting 502 that do not need to be welded, so as to avoid damage caused by some molten solder falling on other parts of the pipe fitting 502.

[0041] The first material separating plate 64 and the second material separating plate 65 are used to isolate and protect other parts of the pipe fitting 502 except the welded part; A bent rod 66 is fixedly connected to the outside of the laser welding assembly 63. The bottom of the bent rod 66 is fixedly connected to a partition plate 67. A straight rod 68 is fixedly connected to the outside of the partition plate 67. One end of the straight rod 68 away from the partition plate 67 is fixedly connected to an arc groove frame 69. A deflecting rod 60 is slidably fitted inside the arc groove frame 69. A bent rod 66 is fixedly connected to the outside of the laser welding assembly 63, and the bottom end of the bent rod 66 is connected to the partition plate 67. The partition plate 67 plays a role in separating the welding head of the laser welding assembly 63 to avoid high heat generated by the laser from affecting the other components in the welding mechanism 6 and causing high-temperature damage. In addition, the partition plate 67 is made of an alumina ceramic plate.

[0042] The partition plate 67 is used to separate the laser welding assembly 63 from the other side thereof to achieve heat insulation treatment; The bottom end of the deflecting rod 60 is fixedly connected to a frame body 601. A wheel body 603 is rotatably installed on the outside of the frame body 601 through a support. The wheel body 603 rolls on one side of the pipe fitting 502 that needs to be welded. A resilient scraping piece 604 is fixedly connected to the outer end face of the frame body 601; Among them, the resilient scraper 604 is used to clean the impurities on the side of the pipe fitting 502 that needs to be welded; the other side of the partition plate 67 is connected to the frame body 601 through an elastic member, and the frame body 601 is rotatably installed with a wheel body 603 through a support, and the wheel body 603 rolls at the part of the pipe fitting 502 that needs to be welded. In addition, the other end of the frame body 601 far from the partition plate 67 is connected to the resilient scraper 604. Therefore, when the laser welding assembly 63 moves forward, the partition plate 67 will drive the frame body 601 to move forward. At this time, the resilient scraper 604 plays a role in cleaning some impurities and oxides adhering to the welding surface of the pipe fitting 502 that needs to be welded.

[0043] One end of the frame body 601 far from the resilient scraper 604 is fixedly connected to the partition plate 67 through an elastic member.

[0044] An extension plate 71 is slidably fitted outside the laser welding assembly 63. Both the upper and lower sides of the extension plate 71 are fixedly connected with folding pieces 73, and one end of the folding piece 73 far from the extension plate 71 is fixedly connected to the laser welding assembly 63; when there is a partial depression on the surface of the pipe fitting 502 that needs to be welded, at this time, the wheel body 603 and part of the frame body 601 will "sink" into the depression. At this time, when observing the frame body 601 from a top-down perspective, it will move to the right or deflect counterclockwise, and the deflection rod 60 connected to its top will move to the right or deflect counterclockwise along the arc groove frame 69. At the same time, the top inclined block 75 connected to the top of the deflection rod 60 will also move outward and away from the hyperbolic block 74. The contacting surfaces of the hyperbolic block 74 and the top inclined block 75 are both inclined surfaces. Therefore, as the top inclined block 75 moves outward, the extension plate 71 connected to the hyperbolic block 74 will drive the focusing lens 72 to move downward. At this time, the light spot of the light beam passing through the focusing lens 72 will gradually become larger, so as to play a role in avoiding improper welding of the depressed part due to too small a light spot when there is a depression problem at the part of the pipe fitting 502 that needs to be welded.

[0045] The inner end of the extension plate 71 is fixedly connected with a focusing lens 72, and the end of the extension plate 71 far from the focusing lens 72 is fixedly connected with a hyperbolic block 74. Both sides of the hyperbolic block 74 are extrusion-fitted with top inclined blocks 75, and the bottom end of the top inclined block 75 is fixedly connected to the deflection rod 60; similarly, when there is a convex problem at the part of the pipe fitting 502 that needs to be welded, the top inclined block 75 will move towards the center and squeeze the hyperbolic block 74 upward, so that the focusing lens 72 moves upward. At this time, the light spot of the light beam passing through the focusing lens 72 will gradually become smaller, so as to play a role in avoiding overwelding of the convex part due to too large a light spot when there is a convex problem at the part of the pipe fitting 502 that needs to be welded.

[0046] A limiting plate 76 is fixedly connected to the outer side of the laser welding assembly 63 and is symmetrically arranged on both sides of the top inclined block 75. The folding pieces 73 fixedly connected to the upper and lower sides of the hyperbolic block 74 are foldable, and the limiting plates 76 arranged on both sides of the top inclined block 75 play a role in limiting it.

[0047] When the present invention is in use: First, the pipe fitting 502 is sequentially passed through the adjusting handle 57 and the square sleeve 501. Then, the pipe fitting 502 passing through the former two is placed on the roller body fixedly connected to the inside of the roller support 3. Finally, the front end of the pipe fitting 502 is placed on one end of the slide rail 1 close to the welding mechanism 6. After the two pipe fittings 502 are placed, the adjusting handle 53 is rotated clockwise, so that the rotating shaft 54 connected to its central part will deflect clockwise accordingly. The other end of the rotating shaft 54 is connected to the gearbox 55, and the other side of the gearbox 55 is connected to two threaded rods 56. Therefore, the two threaded rods 56 will rotate in the same direction, and the two threaded rods 56 are also threadedly connected to the two adjusting handles 57. However, the thread patterns between the two adjusting handles 57 and the threaded rods 56 are opposite, so that the two adjusting handles 57 will move synchronously and in opposite directions. One end of the threaded rod 56 away from the gearbox 55 is rotatably installed inside the end face table 51. Therefore, the threaded rod 56 is positioned and rotated and cannot move. The central part of the threaded rod 56 is connected to the socket disc 50 through a bearing 59, and the socket disc 50 is fixedly connected to the inner side of the end face table 51, and the end face table 51 is used for distance determination of the minimum distance between the welds of the two pipe fittings 502.

[0048] After the distance between the two pipe fittings 502 is adjusted, an external power device is used to drive the sliding rod 62 to move forward in the side rail 61. The top of the sliding rod 62 is connected to the laser welding assembly 63. Therefore, the laser welding assembly 63 will move forward and perform laser welding on the gap between the two pipe fittings 502. A first baffle 64 is provided at the top of the pipe fitting 502, and the first baffle 64 is slidably fitted in the second baffle 65. Therefore, the two will protect other parts of the pipe fitting 502 that do not need to be welded. A bent rod 66 is fixedly connected to the outside of the laser welding assembly 63, and the bottom end of the bent rod 66 is connected to the partition plate 67. The other side of the partition plate 67 is connected to the frame 601 through an elastic member. The frame 601 is rotatably installed with a wheel body 603 through a support, and the wheel body 603 rolls on the part of the pipe fitting 502 that needs to be welded. In addition, the other end of the frame 601 away from the partition plate 67 is connected to the resilient scraper 604. Therefore, with the forward movement of the laser welding assembly 63, the partition plate 67 will drive the frame 601 to move forward. At this time, the resilient scraper 604 will clean some impurities and oxides adhering to the surface of the pipe fitting 502 that needs to be welded. When there are some depressions on the surface of the pipe fitting 502 that needs to be welded, at this time, the wheel body 603 and part of the frame 601 will "sink" into the depression. At this time, when observing the frame 601 from a top-down perspective, it will move to the right or deflect counterclockwise. The deflection rod 60 connected to its top will move to the right or deflect counterclockwise along the arc groove frame 69. At the same time, the top inclined block 75 connected to the top end of the deflection rod 60 will also move outward and away from the hyperbolic block 74. The surfaces of contact between the hyperbolic block 74 and the top inclined block 75 are both inclined surfaces. Therefore, with the outward movement of the top inclined block 75, the extension plate 71 connected to the hyperbolic block 74 will drive the focusing lens 72 to move downward. At this time, the light spot of the light beam passing through the focusing lens 72 will gradually become larger. Similarly, when there is a protrusion problem at the part of the pipe fitting 502 that needs to be welded, the top inclined block 75 will move towards the center and squeeze the hyperbolic block 74 upward, so that the focusing lens 72 moves upward. At this time, the light spot of the light beam passing through the focusing lens 72 will gradually become smaller.

[0049] The above embodiments are only the preferred embodiments of the present invention and cannot be used to limit the scope of protection of the present invention. Those of ordinary skill in the art, starting from the above concepts, without creative labor, make various transformations, which all fall within the scope of protection of the present invention.
