Description

Technical Field

[0001] The present invention relates to the field of welding equipment, and more particularly to a stainless steel evaporator welding device. Background Art

[0002] An evaporator, also known as a heat exchanger, is a device that transfers some of the heat from a hot fluid to a room-temperature fluid being exchanged. Heat exchangers are widely used, such as radiators used for heating in daily life, condensers in steam turbines, and oil coolers on space rockets. They are also widely used in the chemical, petroleum, power, and atomic energy industries.

[0003] Deficiencies of existing technology: Currently, in the manufacturing process of high-temperature evaporator tubes, metal sheets need to be cut and rolled, and the preliminarily formed tubes need to be welded after rolling. If the sheet itself has a certain elasticity during welding, a larger weld will be produced after rolling, making welding more difficult.

[0004] To solve the above problems, a Chinese patent with authorization announcement number CN213497470U discloses a welding device for the production of air-conditioning evaporators. The device is provided with an installation box to conveniently fix the evaporator, and the operation is simple and convenient. The fixing mechanism makes the turning and flipping of the evaporator easier and faster, greatly reducing the labor intensity of the staff and improving work efficiency to a certain extent. However, the evaporator tube needs to be manually repositioned. During the position change process, cracks may appear at the weld under the action of external force, resulting in reduced welding quality. Summary of the Invention

[0037] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention; it is obvious that the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0038] See also Figures 1 to 7A stainless steel evaporator welding device includes a base 1, a support roller 2 is fixedly connected to the middle of the top of the base 1, a second electric slide rail 8 is provided in the middle of both sides of the upper surface of the base 1, a mounting frame 3 is slidably connected to the inside of the second electric slide rail 8, a first hydraulic rod 4 is fixedly connected to the top of the mounting frame 3, a welding gun 5 is fixedly connected to the output end of the first hydraulic rod 4, and a rotating component 6 for rotating the evaporator is provided at one end of both sides of the upper surface of the base 1.

[0039] like Figure 2 As shown, the rotating assembly 6 includes a first electric slide rail 61 fixed at one end on both sides of the upper surface of the base 1 and an impact assembly 68 arranged inside the mounting frame 3. The internal sliding connection side plate 62 of the first electric slide rail 61 is fixedly connected to a fixed plate 63 between the two side plates 62. One side of the fixed plate 63 is fixedly connected to a first drive motor 64. The output end of the first drive motor 64 is fixedly connected to a rotating plate 66. Two slots 610 are provided inside the rotating plate 66. One side of the rotating plate 66 is fixedly connected to a second hydraulic rod 67. The output end of the second hydraulic rod 67 is fixedly connected to an arc-shaped clamping plate 65.

[0040] One side of the arc-shaped clamping plate 65 is located inside the slot 610 and slides therein. An anti-slip pad is provided on the inner side of the arc-shaped clamping plate 65 . The arc-shaped clamping plate 65 is in an arc shape.

[0041] The evaporator tube to be welded is placed between the two arc-shaped clamping plates 65, and the two second hydraulic rods 67 are started to drive the arc-shaped clamping plates 65 to move. The two arc-shaped clamping plates 65 clamp and fix the evaporator tube. The two side plates 62 are driven to move by starting the first electric slide rail 61. The two side plates 62 drive the evaporator tube to move below the welding gun 5 until the welding point of the evaporator tube is directly below the welding gun 5. The first hydraulic rod 4 drives the welding gun 5 to weld. At this time, the first drive motor 64 is started to drive the rotating plate 66 to rotate as a whole, thereby driving the evaporator tube to rotate and changing the welding position. Therefore, the position can be changed without disassembling the fixed evaporator, reducing the disassembly time and avoiding external force from tearing the weld that is not tightly connected, thereby improving the efficiency and quality of welding.

[0042] like Figure 3 As shown, the impact assembly 68 includes a second drive motor 681 fixed on one side of the mounting frame 3 and two vibration rods 684 sliding inside the mounting frame 3, one side of the vibration rod 684 is fixedly connected to a rubber ball 686, one side of the two vibration rods 684 is fixedly connected to a transmission rod 682, the outer surface of the vibration rod 684 is sleeved with a first spring 683, the outer surface of the vibration rod 684 is fixedly connected to a drive rod 685, the output end of the second drive motor 681 is fixedly connected to a rotating shaft 688, and the outer surface of the rotating shaft 688 is fixedly connected to two triangular blocks 687.

[0043] One side of the rotating shaft 688 passes through the interior of the mounting frame 3, and the two sides of the first spring 683 are fixed to the mounting frame 3 and the transmission rod 682 respectively. The two triangular blocks 687 are symmetrically fixed on the outer surface of the rotating shaft 688 about the center of the circle. The driving rod 685 and the hypotenuse of the triangular block 687 slide with each other. A polishing component 69 for polishing the welding joint is provided inside the rotating shaft 688.

[0044] When all the evaporator tubes are welded, there will be some welding slag at the welding point, which needs to be removed in time. After welding, the second drive motor 681 is turned on in time to drive the rotating shaft 688 to rotate. The rotating shaft 688 also drives the two triangular blocks 687 to rotate. The triangular blocks 687 rotate in a circle. The hypotenuse of the triangular blocks 687 contacts the driving rod 685. The hypotenuse of the triangular blocks 687 pushes the driving rod 685 toward the mounting bracket 3, driving the rubber ball 686 away from the evaporator. The transmission rod 682 pulls the first spring 683 to stretch. When the triangular block 687 passes the driving rod 685, the rubber ball 686 quickly returns to its original position under the elastic force of the first spring 683, impacting the welding point to knock the welding slag off the evaporator. The rotating shaft 688 rotates continuously, causing the rubber ball 686 to continuously impact. While the rubber ball 686 is knocking out, the first drive motor 64 drives the evaporator to rotate, thereby completely knocking out the welding slag.

[0045] like Figure 3-4 As shown, the polishing assembly 69 includes a receiving groove 694 opened inside the rotating shaft 688, one side of the receiving groove 694 is fixedly connected to the second spring 693, one side of the second spring 693 is fixedly connected to the rectangular rod 691, and one side of the rectangular rod 691 is fixedly connected to the polishing grinding wheel 692.

[0046] The rectangular rod 691 slides inside the receiving groove 694, and the polishing wheel 692 is located between the two rubber balls 686.

[0047] While the rubber ball 686 is knocking off the welding slag, the rotating shaft 688 is rotating synchronously. The rotating shaft 688 drives the polishing wheel 692 to rotate at high speed through the rectangular rod 691. Because the rectangular rod 691 is slidably sleeved inside the rotating shaft 688, when the polishing wheel 692 contacts the evaporator, under the action of the second spring 693, the polishing wheel 692 is always tightly fitted to the welding point, so that the polishing wheel 692 has a better polishing effect and can be operated synchronously with the knocking off operation, which greatly reduces the operating steps after welding, shortens the time for post-weld processing, and improves the practicality of the device.

[0048] like Figure 5 and Figure 7As shown, a cooling component 7 is provided on the side of the upper surface of the base 1 away from the first electric slide rail 61. The cooling component 7 includes a water tank 71 fixed on one side of the upper surface of the base 1. The top of the water tank 71 is fixedly connected to a top plate 72. The top of the top plate 72 is fixedly connected to a water pump 73. The output end of the water pump 73 is fixedly connected to a water pipe 74. The outer surface of the water pipe 74 is evenly fixedly connected to a first connecting pipe 75. The inside of the first connecting pipe 75 is slidably connected to a second connecting pipe 76. The top of the second connecting pipe 76 is fixedly connected to an arc tube 77. The outer surface of the arc tube 77 is provided with an adjustment component 78.

[0049] The interior of the first connecting pipe 75 is interconnected with the interior of the water pipe 74, and the interior of the second connecting pipe 76 is interconnected with the interior of the arc pipe 77. A sealing sleeve is provided on the outer surface of the second connecting pipe 76, and the second connecting pipe 76 and the first connecting pipe 75 slide with each other. The input end of the water pump 73 extends to the interior of the water tank 71, and the outer surface of the water pipe 74 is provided with an adjustment component 78 for adjusting the position of the arc pipe 77.

[0050] like Figure 6 As shown, the adjustment component 78 includes a threaded groove 781 arranged on the outer surface of the water pipe 74, the outer surface of the threaded groove 781 is threadedly connected to an internal threaded tube 782, one side of the internal threaded tube 782 is rotatably connected to a ring 783, and the outer surface of the ring 783 is hinged to a hinged rod 784.

[0051] The other end of the hinged rod 784 is hinged to the arc tube 77 , and the hinged rod 784 is evenly hinged to the outer surface of the ring 783 . The internal threaded tube 782 is threadedly connected to the thread groove 781 , and the internal threaded tubes 782 are connected to each other through the bearing ring 783 .

[0052] After welding is completed, stainless steel has poor thermal conductivity, and the accumulation of welding heat can easily lead to warping. It is necessary to cool the weld in time, otherwise it will cause quality problems at the weld. When the evaporator tube moves toward the bottom of the welding gun 5, it will also approach the cooling component 7, so that the cooling component 7 gradually moves to the inside of the evaporator tube. After welding is completed, start the water pump 73 to transport the water inside the water tank 71 to the inside of the water pipe 74, and then to the inside of the arc tube 77 under the action of the first connecting pipe 75 and the second connecting pipe 76, and finally spray it in the form of atomization by the regulating component 78. While spraying water, the evaporator will rotate under the drive of the first drive motor 64, and the sprayed small water droplets will fully contact the weld, effectively cooling the weld to avoid the high temperature affecting the welding quality and the stainless steel evaporator. At the same time, when the water flow converges at the bottom of the evaporator tube, it can be detected whether there is any water leakage at the weld.

[0053] At the same time, the positions of multiple arc tubes 77 are adjusted according to the diameter of the evaporator tube. When the diameter is too large, the position of the arc tube 77 can be changed so that the arc tube 77 is closer to the welding point. The internal threaded tube 782 is rotated under the action of the thread groove 781, so that the internal threaded tube 782 pushes the ring 783 closer to the arc tube 77. The ring 783 pushes one end of the hinged rod 784 to move, and the hinged rod 784 pushes the arc tube 77 to move, so that the second connecting tube 76 moves inside the first connecting tube 75, so that the arc tube 77 is closer to the welding point, avoiding the arc tube 77 being too far away from the welding point, causing the water mist to be unable to contact the welding point.

[0054] Instructions for use: Place the evaporator tube to be welded between the two arc-shaped clamping plates 65, start the two second hydraulic rods 67 to drive the arc-shaped clamping plates 65 to move, and the two arc-shaped clamping plates 65 clamp and fix the evaporator tube. Start the first electric slide rail 61 to drive the two side plates 62 to move. The two side plates 62 drive the evaporator tube to move below the welding gun 5 until the welding position of the evaporator tube is directly below the welding gun 5. The first hydraulic rod 4 drives the welding gun 5 to weld. At this time, the first drive motor 64 starts to drive the rotating plate 66 to rotate as a whole, thereby driving the evaporator tube to rotate and changing the welding position.

[0055] The second drive motor 681 is turned on to work, driving the rotating shaft 688 to rotate. The rotating shaft 688 also drives the two triangular blocks 687 to rotate. The triangular blocks 687 rotate in a circle. The hypotenuse of the triangular block 687 contacts the driving rod 685. The hypotenuse of the triangular block 687 pushes the driving rod 685 toward the mounting bracket 3, driving the rubber ball 686 away from the evaporator. The transmission rod 682 pulls the first spring 683 to stretch. When the triangular block 687 passes the driving rod 685, the rubber ball 686 quickly returns to its original position under the elastic force of the first spring 683, and strikes the welding part to knock out the welding slag from the evaporator. The rotating shaft 688 rotates continuously, so that the rubber ball 686 strikes continuously. While the rubber ball 686 knocks out the welding slag, the first drive motor 64 drives the evaporator to rotate, so that the welding slag can be completely knocked out.

[0056] When the rotating shaft 688 rotates synchronously, the rotating shaft 688 drives the polishing wheel 692 to rotate at high speed through the rectangular rod 691. Because the rectangular rod 691 is slidably sleeved inside the rotating shaft 688, when the polishing wheel 692 contacts the evaporator, the second spring 693 acts to keep the polishing wheel 692 and the weld tightly together, so that the polishing wheel 692 has a better polishing effect.

[0057] Start the water pump 73 to transport the water inside the water tank 71 to the inside of the water pipe 74, and then transport it to the inside of the arc tube 77 through the action of the first connecting pipe 75 and the second connecting pipe 76. Finally, it is sprayed out in the form of atomization by the adjustment component 78 to cool the welding point. By rotating the internal threaded pipe 782, the position of multiple arc tubes 77 is changed through transmission, so that the water mist can fully contact the welding point.

[0058] The above description is merely a preferred embodiment of the present invention; however, the scope of protection of the present invention is not limited thereto. Any person skilled in the art who, within the technical scope disclosed by the present invention, makes equivalent substitutions or modifications based on the technical solutions and improved concepts of the present invention shall be covered by the scope of protection of the present invention.
