Description

Technical Field

[0001] This invention relates to the field of welding technology, specifically to an aluminum alloy door and window welding platform. Background Technology

[0002] Aluminum alloy doors and windows are favored by many consumers due to their advantages such as environmental protection and energy saving, system composition, and intelligence, and have a significant market share in the door and window market. There are many welding methods, such as AC flame welding and AC argon arc welding. Among them, the welding platform plays a very important role and needs to ensure the stability of the doors and windows during the welding process to improve the welding quality.

[0003] Chinese Patent Publication No. CN216151508U discloses a precision welding device for aluminum alloy doors and windows. This solution involves turning a first lead screw, which drives a threaded rod and simultaneously moves a first limiting plate. This, in turn, causes a second lead screw to rotate, moving a second limiting plate. The rotation of the threaded rod then moves a threaded block, which in turn moves a fixing plate, thus clamping the door or window. Because the fixing plates on both sides move in opposite directions, while the first and second limiting plates move up and down, the door or window to be welded is clamped from all four sides, making the welding process more stable.

[0004] This solution only serves to fix the doors and windows. In actual production, the areas to be welded need to be cleaned before welding, and the surface oxide layer needs to be removed. This will result in higher quality welded products. Summary of the Invention

[0025] Please see Figures 1-8In this embodiment of the invention, an aluminum alloy door and window welding platform includes an operating table 1. Multiple fixed plates 2 are fixedly mounted on the operating table 1. Each fixed plate 2 has a lifting groove 21. A shelf 3 is slidably mounted within the lifting groove 21. A piston rod 4 is fixedly mounted between the bottom of the shelf 3 and the operating table 1. A support frame 5 is movably fitted onto the operating table 1 and is fixedly connected to the shelf 3. A cylinder 6 is axially symmetrically and movably connected to the support frame 5, and a grinding component 7 is mounted on the cylinder 6. The aluminum alloy door or window to be welded is placed on the shelf 3. Then, the piston rod 4 is activated, pushing the shelf 3 upwards along the lifting groove 21 on the fixed plate 2. The rising of the shelf 3 causes the support frame 5 and the cylinder 6 to move upwards. The rising of the cylinder 6 causes the grinding component 7 to move upwards. During the upward movement of the door or window, the area to be welded can be ground to remove the surface oxide layer, effectively improving the welding quality of the door or window. The operating table 1 provides an operating platform for welding doors and windows.

[0026] See Figure 1 and Figure 4 As shown, in this embodiment, preferably, a first fixing rod 8 and a second fixing rod 9 are fixedly connected to the outer side of the cylinder 6. The grinding assembly 7 includes a fixing frame 71, which is fixedly connected to the first fixing rod 8. The fixing frame 71 has a sliding groove 72, and a sliding plate 73 is slidably connected in the sliding groove 72. A steel brush 74 is fixedly connected to one side of the sliding plate 73. In the initial state, the steel brush 74 will not contact the door or window. The rising speed of the door or window to be welded is the same as the rising speed of the grinding assembly 7 on the first fixing rod 8. During the rising of the door or window, the sliding plate 73 moves along the sliding groove 72 of the fixing frame 71 towards the position of the door or window to be welded. The movement of the sliding plate 73 drives the steel brush 74 to move, thereby cleaning the surface of the position of the door or window to be welded and removing the oxide layer on the surface, which can improve the welding quality.

[0027] See Figure 4As shown, in this embodiment, preferably, the sliding plate 73 has an inclined groove 731, and a rotating rod 10 is movably connected in the inclined groove 731. A rotating shaft 11 is fixedly connected to the end of the rotating rod 10 away from the sliding plate 73. The rotating shaft 11 movably passes through the fixed frame 71, and a first gear 12 is movably engaged at the end of the rotating shaft 11 away from the rotating rod 10. During the process of the door and window rising, the first gear 12 rotates, and the rotation of the first gear 12 drives the rotating shaft 11 to rotate. The rotation of the rotating shaft 11 drives the rotating rod 10 to rotate. Since the sliding plate 73 has an inclined groove 731, the rotating rod 10, during its rotation, cooperates with the inclined groove 731 to drive the sliding plate 73 to move back and forth in the sliding groove 72, thereby enabling multiple cleaning of the welding position and further improving the welding quality.

[0028] See Figure 1 As shown, in this embodiment, preferably, a wiping pad 13 is provided at the bottom of the second fixing rod 9, and the height of the bottom surface of the wiping pad 13 is the same as the height of the upper surface of the shelf 3. After the steel brush 74 has cleaned the welding position multiple times, it returns to its initial position and will not contact the door or window. At this time, the cylinder 6 is rotated one revolution. The rotation of the cylinder 6 drives the first fixing rod 8 and the second fixing rod 9 to rotate. The rotation of the second fixing rod 9 drives the wiping pad 13 to rotate. During the rotation of the wiping pad 13, the welding position is wiped, which can remove the impurities left after the steel brush 74 cleans, making it convenient for subsequent welding operations on the welding position.

[0029] See Figure 1 As shown, in this embodiment, preferably, a first rack 14 is provided on one side of the cylinder 6. One end of the first rack 14 is fixedly connected to the surface of the operating table 1. The height of the end of the first rack 14 away from the operating table 1 exceeds the height of the cylinder 6. The first rack 14 meshes with the first gear 12 for transmission. The shelf 3 moves upward under the action of the piston rod 4, which drives the grinding assembly 7 to move upward. During the upward movement, the first gear 12 meshes with the first rack 14, causing the first gear 12 to rotate. The rotation of the first gear 12 can enable the steel brush 74 to clean the welding position multiple times. After the first gear 12 and the first rack 14 are disengaged, the first rack 14 is located below the shelf 3. During the subsequent rotation of the cylinder 6, the first fixed rod 8 and the second fixed rod 9 will not come into contact with the first rack 14.

[0030] See Figure 5As shown, in this embodiment, preferably, the center of the first gear 12 is designed with a sawtooth shape, and a sawtooth block 15 is provided on the outer side of the rotating shaft 11. The sawtooth block 15 engages unidirectionally with the sawtooth part of the center of the first gear 12, and a spring 16 is fixedly connected between the sawtooth block 15 and the rotating shaft 11. During the upward movement of the shelf 3, the first gear 12 will mesh with the first rack 14 to drive the first gear 12 to rotate, thereby realizing the multiple cleaning of the position to be welded by the steel brush 74. During this directional movement, the sawtooth shape of the first gear 12 will engage with the sawtooth block 15 on the rotating shaft 11. At this time, the rotation of the first gear 12 will drive the rotating shaft 11 to rotate, and the rotation of the rotating shaft 11 will drive the rotating rod 10 to rotate, thereby realizing the reciprocating movement of the steel brush 74. When the position to be welded is cleaned by the steel brush 74... After the wiping pad 13 has been wiped, the door and window are welded using a welding torch. After the welding is completed, the cylinder 6 is rotated so that the second fixed rod 9 rotates again, allowing the wiping pad 13 to wipe and clean the welded area. Once all this is done, the welding is complete. The piston rod 4 moves downward, causing the shelf 3 to move downward, so that the first gear 12 and the first rack 14 mesh again. When moving in this direction, the serrated part inside the first gear 12 will not engage with the serrated block 15 on the rotating shaft 11. The rotation of the first gear 12 will press the serrated block 15 downward, thereby compressing the spring 16. At this time, the rotation of the first gear 12 will not drive the rotating shaft 11 to rotate, so the steel brush 74 will not come into contact with the door and window, thus avoiding the impact on the welding quality of the welded area caused by the steel brush 74 coming into contact with the door and window after welding.

[0031] See Figure 6As shown, in this embodiment, preferably, a groove 61 is provided on the outer side of the cylinder 6. The groove 61 is composed of a straight groove and a curved groove. A vertical plate 17 is provided on one side of the cylinder 6. The vertical plate 17 is fixedly connected to the operating table 1. A limit rod 18 is fixedly provided on the side of the vertical plate 17 near the cylinder 6. The limit rod 18 fits against the groove 61. When the shelf 3 moves upward under the action of the piston rod 4, the rise of the shelf 3 drives the support frame 5 to move upward, thereby driving the cylinder 6. As column 6 moves upward, the straight groove of slide 61 first contacts the limiting rod 18 of vertical plate 17 during the ascent. During this process, column 6 does not rotate. Within this distance, the first gear 12 will drive the first rack 14, thereby driving the steel brush 74 to clean the welding area of ​​the door and window and remove the oxide layer. When column 6 continues to rise until the curved groove of slide 61 contacts the limiting rod 18, the first rack 14 is located below the shelf 3. As the shelf 3 continues to move upward, column 6 also continues to rise. The curved groove on cylinder 6 contacts the limiting rod 18. Due to the action of the curved groove and the limiting rod 18, cylinder 6 will rotate as it rises, thereby driving the wiping pad 13 on the second fixed rod 9 to wipe and clean the welding position of the door and window. The length of the curved groove is just enough to make cylinder 6 rotate an integer number of times, that is, the first fixed rod 8 and the second fixed rod 9 will return to the initial position. At this time, piston rod 4 stops moving upward and welding gun is used to weld the door and window. After welding, piston rod 4 moves downward and drives shelf 3 to move downward. The curved groove on the slide 61 on cylinder 6 will cooperate with the limiting rod 18 to make cylinder 6 rotate, thereby driving the wiping pad 13 on the second fixed rod 9 to wipe and clean the welding position. As shelf 3 continues to descend, it will drive the straight groove on the slide 61 of cylinder 6 to contact the limiting rod 18. Due to the connection relationship between the first gear 12 and the sawtooth block 15, steel brush 74 will not contact the door and window, avoiding damage to the newly welded position. When piston rod 4 moves downward to the initial position, the entire welding process can be completed.

[0032] See Figures 7-8 As shown in this embodiment, preferably, multiple positioning components 19 are axially symmetrically arranged on both sides of the shelf 3. A second rack 20 is connected to one side of the positioning component 19, and the second rack 20 is fixedly connected to the surface of the operating table 1. When the shelf 3 moves upward, the positioning component 19 and the second rack 20 will be driven, and the positioning component 19 will limit and fix the doors and windows placed in the shelf 3, ensuring the stability of the doors and windows during the welding process and improving the welding quality.

[0033] In this embodiment, preferably, the positioning component 19 includes a fixing block 191, which is fixedly connected to the shelf 3. A round rod 192 is movably disposed through the center of the fixing block 191. A slot 193 is formed in the center of the fixing block 191, and a positioning rod 194 is movably connected in the slot 193. The positioning rod 194 is threadedly connected to the round rod 192. A second gear 195 is fixedly connected to one end of the positioning rod 194. The second gear 195 meshes with the second rack 20 for transmission. When the shelf 3 rises, it causes the fixing block 191 to move upward. The movement of the fixing block 191 drives the second gear 195 to move upward. The wheel 195 moves upward, thereby driving the second rack 20 and causing the second gear 195 to rotate. The rotation of the second gear 195 drives the round rod 192 to rotate. Since the round rod 192 and the positioning rod 194 are connected by a threaded fit, the rotation of the round rod 192 drives the positioning rod 194 to move along the slot 193 towards the door and window until it contacts the door and window, thereby limiting and fixing the door and window. The slot 193 prevents the positioning rod 194 from rotating with the rotation of the round rod 192. Some soft pads can be placed at the end of the positioning rod 194 to prevent damage to the appearance of the door and window when the positioning rod 194 comes into contact with the door and window.

[0034] The working principle of this invention is as follows: The aluminum alloy door / window to be welded is placed on the shelf 3. Then, the piston rod 4 is activated, pushing the shelf 3 upwards along the lifting groove 21 opened in the fixed plate 2. The rise of the shelf 3 drives the support frame 5 and the cylinder 6 upwards. During the rise of the cylinder 6, the straight groove portion of the slide 61 first contacts the limiting rod 18 of the vertical plate 17. During this process, the cylinder 6 does not rotate. During the rise, the first gear 12 meshes with the first rack 14, causing the first gear 12 to rotate. During this directional movement, the sawtooth shape of the first gear 12 engages with the sawtooth block 15 on the rotating shaft 11. At this time, the rotation of the first gear 12 drives the rotating shaft 11 to rotate. The rotation of rod 10 causes the rotating rod 10 to rotate. Since the sliding plate 73 has a groove 731, the rotating rod 10 rotates and cooperates with the groove 731 to drive the sliding plate 73 to move back and forth in the sliding groove 72, thereby achieving multiple cleaning of the welding position. When the cylinder 6 continues to rise until the curved groove part of the sliding groove 61 contacts the limiting rod 18, the first rack 14 is located below the shelf 3. As the shelf 3 continues to move upward, the cylinder 6 also continues to rise. The curved groove part on the cylinder 6 contacts the limiting rod 18. Due to the action of the curved groove and the limiting rod 18, the cylinder 6 also rotates during the rising process, thereby driving the wiping pad 13 on the second fixed rod 9 to wipe and clean the welding position of the door and window. The length of the curved groove is just enough to allow the cylinder 6 to rotate an integer number of revolutions, meaning the first fixed rod 8 and the second fixed rod 9 will return to their initial positions. At this point, the piston rod 4 stops moving upwards, and the welding torch is used to weld the door and window. After welding, the piston rod 4 moves downwards, causing the shelf 3 to move downwards. The curved groove portion of the slide 61 on the cylinder 6 will engage with the limit rod 18, causing the cylinder 6 to rotate and thus driving the wiping pad 13 on the second fixed rod 9 to wipe and clean the welded area. As the shelf 3 continues to descend, it will cause the straight groove portion of the slide 61 on the cylinder 6 to contact the limit rod 18. Due to the connection relationship between the first gear 12 and the sawtooth block 15, the steel brush 74 will not contact the door and window, avoiding damage to the newly welded area. At the same time, the shelf 3 will rise... The fixed block 191 moves upward, and the movement of the fixed block 191 drives the second gear 195 to move upward, thereby transmitting power to the second rack 20 and causing the second gear 195 to rotate. The rotation of the second gear 195 drives the round rod 192 to rotate. Since the round rod 192 and the positioning rod 194 are connected by a threaded fit, the rotation of the round rod 192 drives the positioning rod 194 to move along the slot 193 towards the door and window until it contacts the door and window, thereby limiting and fixing the door and window. The slot 193 can prevent the positioning rod 194 from rotating with the rotation of the round rod 192. Some soft pads can be placed at the end of the positioning rod 194 to prevent damage to the appearance of the door and window when the positioning rod 194 abuts against it.
