Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.
[0032] Example 1: This example helps to solve the problem of weld slag adhering to the weld seam after welding. This slag accumulates in the annular connection seam between the end cap and the aluminum shell and is difficult to remove. If it is not removed in time, it can easily affect the precision of subsequent processing steps of the aluminum shell. Please refer to [link to relevant documentation]. Figure 1 - Figure 8A low-consumption, high-efficiency aluminum casing for a fan and its processing equipment are disclosed. The equipment includes a processing table 1, a fan casing 12 placed on the processing table 1, and a lifting rod 16. A fixed plate 17 is fixedly connected to the outer wall of the lifting rod 16. Multiple first contact blocks 19 are fixedly connected to the fixed plate 17. The first contact blocks 19 are hemispherical. Because there are multiple first contact blocks 19, when the rotating disk 20 rotates, the scraping shovel 40 intermittently moves up and down, performing intermittent tackling actions when scraping the weld slag at the circumferential seam of the fan casing 12 and the end cover 13, further and more evenly cleaning the weld slag with different degrees of adhesion within the weld. A first drive motor 18 is fixedly installed at one end of the lifting rod 16. The first drive motor 18... A rotating disk 20 is fixedly connected to the output end. When the rotating disk 20 rotates, it carries the laser welder 27 in a circular motion, allowing the laser welder 27 to perform circumferential welding on the joint between the fan housing 12 and the end cover 13. The outer wall of the rotating disk 20 has a groove 23, and a bidirectional lead screw 24 is rotatably installed on the inner wall of the groove 23. A first slider 25 and a second slider 26 are threaded onto the bidirectional lead screw 24. A sleeve 28 is fixedly connected to the outer wall of the first slider 25. When the sleeve 28 rotates in a circular motion, it carries a protruding scraper 40 in a synchronous circular motion, allowing the scraper 40 to scrape along the circumferential joint after welding the fan housing 12 and the end cover 13, removing the weld slag accumulated at the weld joint, and completing the initial cleaning operation of the weld slag. A second guide rod 34 is slidably mounted on the inner wall of the sleeve 28, and a scraper 40 is fixedly mounted on one end of the second guide rod 34; a second fixing plate 38 is fixedly connected to the outer wall of the second guide rod 34, and a second return spring 39 is sleeved on the second guide rod 34, with one end of the second return spring 39 fixedly connected to the outer wall of the second fixing plate 38 and the other end of the second return spring 39 fixedly connected to the inner wall of the sleeve 28; a first guide rod 31 is slidably connected to the inner wall of the first slider 25, with a first ball bearing 32 rotatably mounted on one end of the first guide rod 31 and a second ball bearing 33 rotatably mounted on the other end of the first guide rod 31; a first return spring 29 is sleeved on the first guide rod 31, and a first fixing plate 30 is fixedly connected to one end of the first return spring 29. A fixed plate 30 is fixedly connected to the first guide rod 31, and the other end of the first return spring 29 is fixedly connected to the outer wall of the first slider 25; a fixed frame 21 is fixedly connected to the outer wall of the rotating disk 20, and a second drive motor 22 is fixedly installed on the inner wall of the fixed frame 21. The output end of the second drive motor 22 is fixedly connected to one end of the bidirectional lead screw 24; a laser welder 27 for welding the fan housing 12 is fixedly installed on the outer wall of the second slider 26; a plurality of support columns 2 are fixedly connected to the outer wall of the processing table 1, a support canopy 3 is fixedly installed on one end of the support column 2, a hinge 5 is rotatably installed on the support canopy 3, a visible protective door 6 is fixedly connected to the movable end of the hinge 5, and a visible protective plate 4 is fixedly connected to the outer wall of the support canopy 3;An electric slide rail 8 is fixedly installed on the processing table 1. The moving end of the electric slide rail 8 is fixedly connected to a clamping plate 9 for holding the fan housing 12. An electric push rod 10 is fixedly installed on the processing table 1. The output end of the electric push rod 10 is fixedly connected to a push plate 11 for moving the fan housing 12. A hydraulic telescopic cylinder 7 is fixedly installed on the outer wall of the supporting canopy 3. The output end of the hydraulic telescopic cylinder 7 is fixedly connected to one end of the lifting rod 16. The fan housing 12 includes an end cover 13 and a motor mounting base 15. Multiple ventilation slots 14 are provided on the end cover 13. The motor mounting base 15 is fixedly connected to the end cover 13. Activating the hydraulic telescopic cylinder 7 causes the lifting rod 16 to move downwards as a whole. The lifting rod 16 moves downwards along with the rotating disk 20 and the laser welder 27. The fan housing 12 can be correctly positioned by activating the electric push rod 10, which uses the push plate 11 at its output end.
[0033] In this embodiment: When using the low-consumption and high-efficiency aluminum housing for the fan and its processing equipment, the fan housing 12 to be processed is first placed inside the visible protective plate 4 and placed between the two clamping plates 9 on the processing table 1. Then, the electric slide rail 8 is activated to move the two clamping plates 9 closer to each other to clamp and fix the fan housing 12. Then, the end cap 13 is placed on the fan housing 12. Then, the visible protective door 6 is closed by rotating the hinge 5. The visible protective plate 4 and the visible protective door 6 can be observed through the transparency of the visible protective plate 4 and the visible protective door 6.
[0034] Then, the hydraulic telescopic cylinder 7 is activated, which moves the lifting rod 16 downwards. The lifting rod 16 moves the rotating disk 20 and the laser welder 27 downwards. The position of the fan housing 12 can be correctly positioned by activating the electric push rod 10, which drives the push plate 11 at the output end. Then, the hydraulic telescopic cylinder 7 is activated again to bring the weld seam of the laser welder 27, the end cover 13, and the fan housing 12 to the same horizontal position. Then, the second drive motor 22 is activated, which drives the bidirectional lead screw 24 at the output end to rotate. When the bidirectional lead screw 24 rotates, the first slider 25 and the second slider 26 slide closer to each other along the groove 23, so that the lateral position of the laser welder 27 can be adjusted until the position of the laser welder 27 is moved to a position where it can weld the joint between the fan housing 12 and the end cover 13. This operation allows the laser welder 27 to be adapted to weld fan housings 12 of different specifications.
[0035] The laser welder 27 is started for welding, and the first drive motor 18 is started during the welding process. The first drive motor 18 drives the rotating disk 20 to rotate. When the rotating disk 20 rotates, it moves the laser welder 27 in a circle, so that the laser welder 27 can perform circumferential welding on the joint between the fan housing 12 and the end cover 13. During the welding process, as the rotating disk 20 rotates, the rotating disk 20 also moves the sleeve 28 in a circle. When the sleeve 28 rotates in a circle, it moves the protruding scraper 40 in a circle, so that the scraper 40 scrapes along the circumferential joint after the welding of the fan housing 12 and the end cover 13, removing the welding slag accumulated at the weld joint, and completing the preliminary cleaning operation of the welding slag.
[0036] During the welding process, as the rotating disk 20 rotates, it moves the first guide rod 31 in a synchronous circumferential motion. This circumferential movement causes the first ball 32 at one end to intermittently contact the first contact block 19. This contact forces the first guide rod 31 downwards, causing it to slide down the inner wall of the first slider 25 along with the second ball 33. The second ball 33 then contacts the outer wall of the second contact block 35, causing the second contact block 35 to be under force, which in turn forces the second guide rod 34 to slide down the inner wall of the sleeve 28. The downward movement of the second guide rod 34... The second fixing plate 38 moves down synchronously and compresses the second return spring 39, so that the second return spring 39 is in a stored state. At this time, the scraper 40 at one end of the second guide rod 34 also moves down. The scraper 40 will scrape deeper into the weld seam to further remove the weld slag. After the first ball 32 releases contact with the single first contact block 19, the second return spring 39 rebounds from the stored state and moves up along the sleeve 28 with the second guide rod 34 to reset, so that the scraper 40 moves up to reset as well.
[0037] Since there are multiple first contact blocks 19, when the rotating disk 20 rotates, the scraper 40 will move up and down intermittently to scrape the welding slag at the circumferential seam of the fan housing 12 and the end cover 13, and perform intermittent tackling action to further and more evenly clean the welding slag with different degrees of adhesion in the weld.
[0038] Example 2: This example is an improvement upon Example 1. For details, please refer to [link / reference]. Figure 1 - Figure 8The outer wall of the sleeve 28 has a groove 41. The second guide rod 34 is slidably installed in the groove 41. The second guide rod 34 is a square rod, which limits its movement within the groove 41. The outer contour of the second guide rod 34 matches the inner contour of the groove 41, so the second guide rod 34 can only move under the guidance of the groove 41. Two third return springs 42 are fixedly connected to the inner wall of the groove 41. One end of the third return spring 42 abuts against the outer wall of the second guide rod 34; the other end of the second guide rod 34 is fixedly connected to the groove 41. A second contact block 35 is fixedly connected. The second contact block 35 is hemispherical in shape. The hemispherical shape of the second contact block 35 allows the second ball 33 to slide along the hemispherical surface of the second contact block 35 when it contacts the second ball 33. Two third balls 36 are rotatably mounted on the outer wall of the second guide rod 34. Multiple evenly distributed third contact blocks 37 are fixedly connected to the inner wall of the sleeve 28. The third contact blocks 37 are hemispherical in shape. The hemispherical shape of the third contact blocks 37 allows the third ball 36 to be moved by the second guide rod 34 when it contacts the third ball 36.
[0039] In this embodiment: when the rotating disk 20 rotates, when the first ball 32 abuts against the first abutting block 19, as the second guide rod 34 moves down, the second guide rod 34 will simultaneously move the third ball 36 on the outer wall down. When the third ball 36 moves down, it will abut against the third abutting block 37. The abutment causes the second guide rod 34 to move away from the third abutting block 37. When the second guide rod 34 moves, it is limited and guided by the inner wall of the slide groove 41, and when it moves, it compresses the third return spring 42 to store force. Since there are multiple first abutting blocks 19, during the reciprocating movement of the second guide rod 34, it will also intermittently swing left and right slightly. This allows the scraper 40 at one end of the second guide rod 34 to intermittently tug and swing back and forth while scraping along the circumferential seam, further cleaning the weld slag in the weld more evenly.
