[0025] Compared with the prior art, the advantages and positive effects of the present invention are:

[0026] 1. In the present invention, by setting a clamping structure, when the evaporator tube needs to be clamped and fixed, the evaporator tube is directly inserted into the threaded tube, and then the evaporator tube is pulled back and forth to adjust the position of the evaporator tube. When it is adjusted to a suitable position, the handle is rotated, and the handle drives the threaded ring to rotate, and the rotation of the threaded ring drives the buckle ring to rotate, and the rotation of the buckle ring drives the limit ring to move, and the limit ring drives the adjusting member to move. At this time, the adjusting member moves and starts to squeeze the three rollers, and the three rollers start to drive the three rotating plates to rotate, and the three rotating plates start to drive the pressing blocks to move. At this time, the three pressing blocks will shrink inward, and the pressing blocks will clamp and fix the evaporator tube. At this time, the spring A is in a stretched state, and the other evaporator tube is clamped in the same way. Fix it on another clamping structure, and then weld the two evaporator tubes. After the two evaporator tubes are welded, rotate the handle in the opposite direction, and the handle drives the threaded ring to rotate in the opposite direction. The threaded ring will move along the threaded tube in the direction away from the welding plate. At this time, the adjusting part will move in the direction away from the welding plate, and the spring A will give a pulling force to the rotating plate, and the slider will slide along the inner wall of the limiting groove of the welding plate. The rotating plate starts to drive the pressing block to rotate, and the pressing block will be out of contact with the arc surface of the evaporator tube. At this time, the welded evaporator tube can be directly pulled out from the two threaded tubes. By setting the clamping structure, the position of the evaporator tube can be adjusted quickly and conveniently, and the evaporator tube can be quickly fixed.

[0027] 2. In the present invention, by setting an adjusting member, the cross-section of the adjusting member is set to an isosceles trapezoid. When the adjusting member moves, the three round rollers can be squeezed at the same time, so that the three round rollers drive the rotating plate to rotate at the same time, and then the evaporator tube is clamped with the help of the pressing block. The round rollers have the effect of reducing the friction between the adjusting member and the round rollers, so that the evaporator tube can be fixed in the middle position of the threaded tube.

[0028] 3. In the present invention, by setting an adjustment structure, when it is necessary to weld the two evaporator tubes at a specific angle, the rectangular plate is first clamped in the clamping frame, and then the screw is rotated so that the screw is squeezed on the surface of the rectangular plate by means of the thread, so as to achieve the effect of quickly fixing the rectangular plate in the clamping frame, and then the pull rod is pushed to drive the tooth block to move out of the tooth groove on the surface of the fixed block, and then the rectangular plate is rotated to make the rectangular plate rotate to a suitable angle. When the rectangular plate is rotated to a suitable angle, the pull rod is released. At this time, the top plate and the spring B will give the pull rod a pulling force, so that the pull rod drives the tooth block to be clamped in the clamping groove of the fixed block again, so as to achieve the effect of fixing the position of the rectangular plate, and then the clamping structure is used to clamp and fix the evaporator tube, and finally welding is performed. By setting the adjustment structure, it is convenient for the welder to place the evaporator tube at a specific angle, and then the clamping structure is used to clamp and weld the evaporator tube, so that the entire welding tooling is more practical.

[0029] 4. In the present invention, by providing a collecting structure, before welding the evaporator tube, the handle is first pulled to slide the limit bar under the collection box along the slide rail of the pad. When welding the evaporator tube, the waste chips generated by the welding will directly splash onto the slide plate and slide along the slide plate into the collection box, thereby achieving the effect of collecting the waste chips generated in the welding process of the evaporator tube. When it is found that there are more waste chips on the arc surface of the slide plate, which affects the sliding of the waste chips, the scraper is pulled to make the scraper simply clean the inside of the slide plate. After the cleaning of the inside of the slide plate is completed, the scraper is released, and the elastic rope gives the scraper a pulling force to make the scraper return to its original position, thereby achieving the effect of temporarily storing and collecting the scraper. When the waste chips are collected, the handle is pulled to remove the collection box from the pad, and the waste chips are uniformly transferred. By providing a collecting structure, the effect of collecting the waste chips generated during the welding of the evaporator tube is achieved, thereby improving the cleanliness of the entire working environment.

However, the present invention may also be implemented in other ways than those described herein. Therefore, the present invention is not limited to the specific embodiments of the following disclosure.

[0041] Embodiment 1, as Figure 1-8 As shown, the present invention provides an evaporator tube welding tool, including two rectangular plates 1, a pad 408 and a clamping structure 3, the upper surfaces of the two rectangular plates 1 are fixedly connected with a support frame 2, the end of the support frame 2 away from the rectangular plate 1 is provided with a clamping structure 3, the side of the two rectangular plates 1 close to each other is provided with an adjustment structure 4, and the upper surface of the pad 408 is provided with a collecting structure 5.

[0042] The specific settings and functions of the clamping structure 3, the adjusting structure 4 and the collecting structure 5 are described in detail below.

[0043] like Figure 3 and Figure 4As shown, the clamping structure 3 includes a threaded tube 301, which is fixedly connected to the upper end of the support frame 2, and the arc surface of the threaded tube 301 is threadedly connected with a threaded ring 302, and the arc surface of the threaded tube 301 is sleeved with an adjusting piece 303. One end of the threaded tube 301 is evenly welded with three welding plates 304, and the arc surface of the welding plate 304 is provided with a rectangular hole 305. The corners of the two ends of the rectangular hole 305 of the welding plate 304 are rounded, and the inner wall of the rectangular hole 305 is rotatably connected with a rotating plate 306, and one end of the rotating plate 306 is rotatably connected with a pressing block 307, and the end of the rotating plate 306 away from the pressing block 307 is fixedly connected with a round roller 308. When welding the evaporator tube, the evaporator tube can be directly inserted into the threaded tube 301, and can be moved back and forth The evaporation tube is pulled to the position to locate the evaporation tube, and then the three rotating plates 306 are squeezed by means of the adjusting member 303, so that the pressing block 307 squeezes the evaporation tube to fix the evaporation tube, thereby realizing the rapid positioning of the evaporation tube and the fixing and auxiliary welding of the evaporation tube. The arc surface of the welding plate 304 is provided with a limiting groove 309, and the inner wall of the limiting groove 309 of the welding plate 304 is slidably connected with a slider 310, and the side of the slider 310 away from the inner wall of the limiting groove 309 is fixedly connected with a spring A311, and the end of the spring A311 away from the slider 310 is fixedly connected to the rotating plate 306. By adopting this preferred solution, after the evaporation tube is welded, the threaded ring 302 is rotated to make the adjusting member 303 move from the rotating plate 306 When the arc surface of the round roller 308 is disengaged, the spring A311 can apply a pulling force to the rotating plate 306, so that the rotating plate 306 drives the pressing block 307 to disengage from the arc surface of the evaporator tube, thereby facilitating and quickly removing the welded evaporator tube. The arc surface of the threaded ring 302 is fixedly connected with three grips 312, and the three grips 312 are evenly fixedly connected to the arc surface of the threaded ring 302. The end of the grip 312 away from the threaded ring 302 is fixedly connected with a ball. The preferred solution is adopted to facilitate the welding personnel to quickly rotate the threaded ring 302, and then adjust the position of the adjusting member 303 to adjust the rotation angle of the rotating plate 306. The side of the threaded ring 302 close to the adjusting member 303 is fixedly connected with a buckle ring 313, and the inner wall of the buckle ring 313 is rotatably connected to the adjusting member 303. There is a limit ring 314, and the side of the limit ring 314 away from the buckle ring 313 is fixedly connected to the adjusting member 303. By adopting this preferred solution, the threaded ring 302 and the adjusting member 303 can be connected, and then the adjusting member 303 can be pulled to move in a direction away from the welding plate 304 by rotating the threaded ring 302, so that the position of the adjusting member 303 can be adjusted more conveniently. The cross-section of the adjusting member 303 is an isosceles trapezoid, and the end of the adjusting member 303 close to the rotating plate 306 is a pointed end. By adopting this preferred solution, the rotating plates 306 can be squeezed at the same time by means of the adjusting member 303, so that the three rotating plates 306 drive the pressing block 307 to shrink inward at the same time, so that the evaporator tube can be fixed in the middle position of the threaded tube 301.

[0044] The effect achieved by the entire clamping structure 3 is that when the evaporating tube needs to be clamped and fixed, the evaporating tube is directly inserted into the threaded tube 301, and then the evaporating tube is pulled back and forth to adjust the position of the evaporating tube. When it is adjusted to a suitable position, the handle 312 is rotated, and the handle 312 drives the threaded ring 302 to rotate. The rotation of the threaded ring 302 drives the buckle ring 313 to rotate. The rotation of the buckle ring 313 drives the limit ring 314 to move. The limit ring 314 drives the adjusting member 303 to move. At this time, the adjusting member 303 moves to start squeezing the three rollers 308. , the three round rollers 308 start to drive the three rotating plates 306 to rotate, and the three rotating plates 306 start to drive the pressing block 307 to move. At this time, the three pressing blocks 307 will shrink inward, and the pressing block 307 will clamp and fix the evaporation tube. At this time, the spring A311 is in a stretched state. The other evaporation tube is fixed on another clamping structure 3 in the same way, and then the two evaporation tubes are welded. After the two evaporation tubes are welded, the handle 312 is rotated in the opposite direction, and the handle 312 drives the threaded ring 302 to rotate in the opposite direction, and the threaded ring 302 The evaporator tube 306 is moved along the threaded tube 301 in a direction away from the welding plate 304. At this time, the adjusting member 303 is moved in a direction away from the welding plate 304. The spring A311 gives a pulling force to the rotating plate 306. The slider 310 slides along the inner wall of the limit groove 309 of the welding plate 304. The rotating plate 306 starts to drive the pressing block 307 to rotate. The pressing block 307 is out of contact with the arc surface of the evaporator tube. At this time, the welded evaporator tube can be directly pulled out of the two threaded tubes 301. By setting the clamping structure 3, it is convenient and fast to evaporator tube 306. The position of the tube can be adjusted, and the evaporation tube can be quickly fixed. By setting the adjusting member 303, the cross-section of the adjusting member 303 is set to an isosceles trapezoid. When the adjusting member 303 moves, the three round rollers 308 can be squeezed at the same time, so that the three round rollers 308 drive the rotating plate 306 to rotate at the same time, and then the evaporation tube is clamped with the help of the pressing block 307. The round roller 308 reduces the friction between the adjusting member 303 and the round roller 308, so that the evaporation tube can be fixed in the middle position of the threaded tube 301.

[0045] like Figure 5 and Figure 6As shown, the adjustment structure 4 includes two clamping frames 401, and the two clamping frames 401 are respectively sleeved on the ends of the two rectangular plates 1 close to each other, and the side arms of the clamping frames 401 are threadedly inserted with screws 402, and the side of the clamping frame 401 away from the rectangular plate 1 is fixedly connected with a fixed block 403, and a pull rod 404 is slidably inserted in the fixed block 403, and one end of the pull rod 404 is fixedly connected with a tooth block 405, and the side of the fixed block 403 close to the tooth block 405 is provided with a tooth groove matched with the size of the tooth block 405, and the arc surface of the pull rod 404 is fixedly connected with an adjustment plate 406, and the lower end of the adjustment plate 406 is fixedly connected with a welding block 407, and the lower surfaces of the two welding blocks 407 are fixedly connected with pads 408. When it is necessary to weld the two evaporation tubes to a specific angle, the angle of the evaporation tube can be quickly adjusted and fixed, and then the two evaporation tubes can be welded. Welding is performed so that the entire welding tooling can adapt to more welding requirements and is more practical. The arc surface of the pull rod 404 is covered with a top plate, and the arc surface of the pull rod 404 is covered with a spring B412. The two ends of the spring B412 are respectively fixedly connected to the pull rod 404 and the top plate. By adopting this preferred solution, an elastic force can be given to the pull rod 404, so that the gear can be quickly stuck in the tooth groove of the fixed block 403, thereby improving the strength of the tooth block 405 to fix the rotation angle of the adjustment plate 406 to a certain extent. The surface of the adjustment plate 406 is fixedly connected with a circular plate 409, and the upper surface of the fixed block 403 is fixedly connected with a mounting plate 410. The mounting plate 410 has an internal thread inserted with a pressure rod 411. By adopting this preferred solution, the position of the fixed block 403 can be temporarily and simply fixed after the rectangular plate 1 is rotated to a suitable angle.

[0046] The effect achieved by the entire adjustment structure 4 is that, by setting the adjustment structure 4, when it is necessary to weld two evaporation tubes at a specific angle, the rectangular plate 1 is first clamped in the clamping frame 401, and then the screw 402 is rotated so that the screw 402 is squeezed on the surface of the rectangular plate 1 by means of the thread, so that the rectangular plate 1 can be quickly fixed in the clamping frame 401, and then the pull rod 404 is pushed so that the pull rod 404 drives the tooth block 405 to move out of the tooth groove on the surface of the fixing block 403, and then the rectangular plate 1 is rotated to make the rectangular plate 1 rotate to a suitable angle. After the rectangular plate 1 is rotated to a suitable angle, the pull rod 404 is released. At this time, the top plate and the spring B412 will give the pull rod 404 a pulling force, so that the pull rod 404 drives the tooth block 405 to be re-stuck in the slot of the fixed block 403, thereby achieving the effect of fixing the position of the rectangular plate 1, and then the evaporator tube is clamped and fixed by the clamping structure 3, and finally welded. By setting the adjustment structure 4, it is convenient for the welder to place the evaporator tube at a specific angle, and then use the clamping structure 3 to clamp and weld the evaporator tube, making the entire welding tooling more practical.

[0047] like Figure 7 and Figure 8As shown, the collecting structure 5 includes a slide rail 51, which is fixedly connected to the upper surface of the pad 408. The inner wall of the slide rail 51 is slidably connected to a limit strip 52. A side of the limit strip 52 away from the inner wall of the slide rail 51 is fixedly connected to a collecting box 53, and a handle 58 is fixedly connected to one side of the collecting box 53. A slide plate 54 is connected to the side of the collecting box 53 away from the handle 58. Slide holes 55 are provided on both sides of the slide plate 54. A scraper 56 is slidably connected to the inner wall of the slide hole 55 of the slide plate 54. When welding two evaporation tubes, the waste chips generated by welding can be shielded and collected, and the collected waste chips can also be quickly transferred. Elastic ropes 57 are fixedly connected to both ends of the scraper 56, and one end of the elastic rope 57 away from the scraper 56 is fixedly connected to the slide plate 54. By adopting this preferred solution, a pulling force can be applied to the scraper 56. After the scraper 56 is used to scrape and clean the waste chips on the slide plate 54, the scraper 56 can be temporarily stored and fixed.

[0048] The effect achieved by the entire collecting structure 5 is that, by setting the collecting structure 5, before welding the evaporating tube, the handle 58 is pulled first to slide the limit bar 52 below the collecting box 53 along the slide rail 51 of the pad 408. When welding the evaporating tube, the waste generated by welding will directly splash onto the slide plate 54 and slide along the slide plate 54 into the collecting box 53, thereby achieving the effect of collecting the waste generated during the welding of the evaporating tube. When it is found that there are a lot of waste chips on the arc surface of the slide plate 54, which affects the sliding of the waste chips, the scraper 56 is pulled to scrape the waste chips. The scraper 56 performs a simple cleaning of the inside of the slide plate 54. After the cleaning of the inside of the slide plate 54 is completed, the scraper 56 is loosened, and the elastic rope 57 will give the scraper 56 a pulling force to return the scraper 56 to its original position, thereby achieving the effect of temporarily storing the scraper 56. After the waste chips are collected, the handle 58 is pulled to remove the collection box 53 from the pad 408, and the waste chips are uniformly transferred. By setting the collection structure 5, the waste chips generated during the welding of the evaporator tube can be collected, thereby improving the cleanliness of the entire working environment.

[0049] Embodiment 2, on the basis of embodiment 1, the collecting structure 5 comprises a slide rail 51, the slide rail 51 is fixedly connected to the upper surface of the pad 408, the inner wall of the slide rail 51 is slidably connected to a limit strip 52, a side of the limit strip 52 away from the inner wall of the slide rail 51 is fixedly connected to a collecting box 53, a side of the collecting box 53 is fixedly connected to a handle 58, a side of the collecting box 53 away from the handle 58 is connected to a slide plate 54, both sides of the slide plate 54 are provided with slide holes 55, and the inner wall of the slide hole 55 of the slide plate 54 is slidably connected to a scraper 5 6. When welding two evaporation tubes, the waste generated by welding can be shielded and collected. The collected waste can also be quickly transferred. Both ends of the scraper 56 are fixedly connected with elastic ropes 57. The end of the elastic rope 57 away from the scraper 56 is fixedly connected to the slide plate 54. By adopting this preferred solution, a pulling force can be applied to the scraper 56. After the scraper 56 is used to scrape and clean the waste on the slide plate 54, the scraper 56 can be temporarily stored and fixed. Before welding the evaporation tube, first pull the handle 58 to slide the limit bar 52 under the collection box 53 along the slide rail 51 of the pad 408. When welding the evaporation tube, the waste generated by welding will directly splash onto the slide plate 54 and slide along the slide plate 54 into the collection box 53, so as to achieve the effect of collecting the waste generated during the welding of the evaporation tube. When it is found that there are a lot of waste on the arc surface of the slide plate 54, which affects the sliding of the waste, pull the scraper 56 to make the scraper 56 simplifies the inside of the slide plate 54. Single cleaning, after cleaning the inside of the slide plate 54, loosen the scraper 56, the elastic rope 57 will give the scraper 56 a pulling force, so that the scraper 56 returns to the original position, achieving the effect of temporarily storing the scraper 56, when the waste chips are collected, pull the handle 58, remove the collection box 53 from the pad 408, and transfer the waste chips in a unified manner. By setting up the collection structure 5, the waste chips generated during the welding of the evaporator tube can be collected, thereby improving the cleanliness of the entire working environment.

[0050] The working principle of the whole device is as follows: when it is necessary to weld two evaporation tubes at a specific angle, first clamp the rectangular plate 1 in the clamping frame 401, then rotate the screw 402 so that the screw 402 is pressed on the surface of the rectangular plate 1 by means of the thread, so as to achieve the effect of quickly fixing the rectangular plate 1 in the clamping frame 401, then push the pull rod 404 so that the pull rod 404 drives the tooth block 405 to move out of the tooth groove on the surface of the fixing block 403, then rotate the rectangular plate 1 so that the rectangular plate 1 is rotated to a suitable angle, and when the rectangular plate 1 is rotated to a suitable angle, release the pull rod 404, at this time the top plate and the spring B412 will give the pull rod 404 a pulling force, so that the pull rod 404 drives the tooth block 405 to be clamped in the clamping groove of the fixing block 403 again, so as to achieve the effect of fixing the position of the rectangular plate 1, and then use the clamping structure 3 to clamp and fix the evaporation tube, and finally perform welding;

[0051] When the evaporator tube needs to be clamped and fixed, the evaporator tube is directly inserted into the threaded tube 301, and then the evaporator tube is pulled back and forth to adjust the position of the evaporator tube. When it is adjusted to the appropriate position, the handle 312 is rotated, and the handle 312 drives the threaded ring 302 to rotate. The rotation of the threaded ring 302 will drive the buckle ring 313 to rotate. The rotation of the buckle ring 313 will drive the limit ring 314 to move. The limit ring 314 drives the adjusting member 303 to move. At this time, the adjusting member 303 moves and begins to squeeze the three rollers 308. The three rollers 308 begin to drive the three rotating plates 306 to rotate. The three rotating plates 306 begin to drive the pressing blocks 307 to move. At this time, the three pressing blocks 307 will shrink inward, and the pressing blocks 307 will clamp and fix the evaporator tube. At this time, the spring A311 is in a stretched state. Use the same method to fix another evaporator tube on another clamping structure 3, and then weld the two evaporator tubes. After the two evaporator tubes are welded, rotate the handle 312 in the opposite direction. 12 drives the threaded ring 302 to rotate in the opposite direction, and the threaded ring 302 will move along the threaded tube 301 in the direction away from the welding plate 304. At this time, the adjusting member 303 will move in the direction away from the welding plate 304, and the spring A311 will give a pulling force to the rotating plate 306, and the slider 310 will slide along the inner wall of the limiting groove 309 of the welding plate 304. The rotating plate 306 begins to drive the pressing block 307 to rotate, and the pressing block 307 will be out of contact with the arc surface of the evaporator tube. At this time, the welded evaporator tube can be directly extracted from the two threaded tubes 301. The cross section of the adjusting member 303 is set to be an isosceles trapezoid. When the adjusting member 303 moves, it can realize the simultaneous extrusion of the three rollers 308, so that the three rollers 308 drive the rotating plate 306 to rotate at the same time, and then the evaporator tube is clamped by the pressing block 307. The roller 308 has the effect of reducing the friction between the adjusting member 303 and the roller 308, so that the evaporator tube can be fixed in the middle position of the threaded tube 301.

[0052] Before welding the evaporator tube, the handle is pulled first to slide the limit bar 52 under the collection box 53 along the slide rail 51 of the pad 408. When welding the evaporator tube, the waste generated by welding will directly splash onto the slide plate 54 and slide along the slide plate 54 into the collection box 53, thereby achieving the effect of collecting the waste generated in the process of welding the evaporator tube. When it is found that there are a lot of waste chips on the arc surface of the slide plate 54, which affects the sliding of the waste chips, the scraper 56 is pulled to make the scraper 56 simply clean the inside of the slide plate 54. After the cleaning of the inside of the slide plate 54 is completed, the scraper 56 is released, and the elastic rope 57 will give the scraper 56 a pulling force to make the scraper 56 return to its original position, thereby achieving the effect of temporarily storing and collecting the scraper 56. When the waste chips are collected, the handle is pulled to remove the collection box 53 from the pad 408, and the waste chips are uniformly transferred.
