Technical Field

[0001] The invention relates to the technical field of air conditioner welding, in particular to automatic production welding equipment for air conditioners. Background Art

[0002] An air conditioner is a device used to adjust the temperature, humidity, cleanliness and other parameters of the ambient air in a building. An air conditioner is mainly composed of a compressor, condenser, evaporator, four-way valve, refrigerant pipe and other structures. The refrigerant pipe is mainly composed of copper pipes and is used to transport the refrigerant to the compressor, evaporator, four-way valve and other structural components.

[0003] The copper tube inside the air conditioner is composed of several tube bodies. When producing the air conditioner, the copper tube needs to be welded and connected to form a refrigerant pipeline.

[0004] There are two main ways to weld copper tubes in air conditioners. One is to wrap the connecting ends of the two sections of copper tubes manually and then weld them together. The other way is to use automated welding to butt the joints of the two sections of copper tubes together and then connect them together through welding. The advantages of manual welding are firm welding, good welding sealing effect at the copper tube joints, and not easy to separate.

[0048] A semicircular fixing ring 5 is fixedly installed at one end corresponding to the welding seat 1 2 and the welding seat 2 3 . A plurality of fixing plates 51 are distributed circumferentially inside the fixing ring 5 . The fixing plates 51 are radially sealed and slidably installed inside the fixing ring 5 .

[0049] A sealed air cavity 52 is provided on the inner side of the fixing plate 51, and an air pressure tube 53 is installed inside the fixing ring 5. The air pressure tube 53 is connected to the air pressure generating device, and the air pressure tube 53 is communicated with several air cavities 52. By increasing the air pressure in the air cavity 52, the copper tube inside the fixing ring 5 is clamped and fixed by the fixing plate 51.

[0050] The other ends corresponding to welding seat 1 2 and welding seat 2 3 are both axially slidably installed with a semicircular moving ring 6, and a number of unidirectional rotating fixed wheels 61 are distributed circumferentially inside the moving ring 6. The fixed wheel 61 is used to position and support the copper tube inside the moving ring 6. A ratchet and pawl assembly 612 composed of a ratchet and a pawl is provided inside the fixed wheel 61. The pawl is set in the inner ring wall of the fixed wheel 61, and the ratchet is fixedly installed in the moving ring 6. The unidirectional rotation of the fixed wheel 61 is realized by the cooperation of the ratchet and the pawl.

[0051] The surface of the fixed wheel 61 is provided with an extrusion ring 611 made of rubber material. When the copper tube moves toward another section of the copper tube inside the movable ring 6, the fixed wheel 61 can rotate. The unidirectional rotation of the fixed wheel 61 is used to prevent the copper tube inside the movable ring 6 from moving toward the outer ends of the welding seat 1 2 and the welding seat 2 3.

[0052] When the welding seat 1 2 and the welding seat 2 3 are combined into a cylindrical shape, circular channels are formed at both ends of the welding seat 1 2 and the welding seat 2 3, and two sections of copper pipes are placed using the circular channels at both ends.

[0053] When welding seat 1 2 and welding seat 2 3 are in a state of being separated from each other, two sections of copper tubes are placed between welding seat 1 2 and welding seat 2 3, and hydraulic rod 1 4 is used to drive welding seat 1 2 and welding seat 2 3 to rotate closer to each other until welding seat 1 2 and welding seat 2 3 are combined into a cylindrical shape. At this time, the two sections of copper tubes are respectively placed in the circular channels formed at both ends of welding seat 1 2 and welding seat 2 3.

[0054] The interior of welding seat 1 2 and welding seat 2 3 are both provided with semicircular slide rails 7 for axial sliding.

A semicircular gear cylinder 17 is fixedly installed inside the drive ring 8. A gear part meshing with the gear cylinder 17 is installed inside welding seat 1 2 and / or welding seat 2 3. The axial tooth length of the gear part is smaller than the axial tooth length of the gear cylinder 17. This design can enable the gear cylinder 17 to remain in meshing with the gear part when the drive ring 8 moves axially. The gear part is driven to rotate by a motor device installed inside welding seat 1 2 or welding seat 2 3.

[0055] A semi-annular side slide groove 81 is provided on the side surface of the driving ring 8, and a hydraulic rod 2 18 is installed on the outer surfaces of the welding seat 1 2 and the welding seat 2 3. The hydraulic rod 2 18 is connected to the hydraulic control system, and a connecting block 181 is fixedly installed on the telescopic end of the hydraulic rod 2 18, and the connecting block 181 is adapted to the side slide groove 81.

[0056] A trimming block 9 and a welding block 21 are installed on the inner side of the driving ring 8. A flame nozzle and a welding fiber wire feeding port are provided on one side of the welding block 21 close to the axial direction of the welding seat 1 2 or the welding seat 2 3. The welding fiber wound on the reel is installed inside the welding block 21. By controlling the rotation of the reel, the welding fiber can be sent out from the welding fiber wire feeding port (the welding fiber wire feeding structure adopts the existing technology). An expansion portion 91 is provided on the side of the trimming block 9 close to the driving ring 8. The expansion portion 91 is an outer arc surface to avoid interference between the expansion portion 91 and the inner wall of the copper tube when expanding the copper tube. An extrusion portion 92 is provided on the other side. The two side surfaces of the extrusion portion 92 in the circumferential rotation direction and the extrusion portion 92 are transitional arc surfaces to avoid interference between the extrusion portion 92 and the outer surface of the copper tube when extruding the copper tube.

[0057] A support 12 is fixedly installed on the surface of the trimming block 9 close to the driving ring 8, and a U-shaped part 121 is fixedly installed on the surface of the support 12. An adjusting rod 10 is rotatably installed inside the support 12, and an adjusting rod 2 11 is axially sleeved inside the upper end of the adjusting rod 10; the adjusting rod 2 11 extends to one end of the adjusting rod 10 and is provided with an annular groove 1101 and an axially distributed linear groove 1102, and the linear groove 1102 is T-shaped and is connected to the annular groove 1101.

[0058] A rotating rod 13 is installed inside the adjusting rod 10 for rotation, and a motor for driving the rotating rod 13 to rotate is installed on the upper surface of the support 12. The upper end of the rotating rod 13 extends to the inside of the adjusting rod 2 11, and a limit block 132 is provided on the upper end of the adjusting rod 2 11. The limit block 132 is combined with the adjusting rod 2 11 to form a T-shaped rod. The limit block 132 can be adapted to the annular groove 1101 and the linear groove 1102. When the limit block 132 is located in the linear groove 1102, the adjusting rod 10 and the adjusting rod 2 11 are in an axially sliding state. When the limit block 132 is located in the annular groove 1101, the adjusting rod 10 and the adjusting rod 2 11 are in an axially fixed state.

[0059] A block 14 is radially slidably installed on the side wall of the adjusting rod 10, a return spring is provided between the block 14 and the inner wall of the adjusting rod 10, and a slot is provided at the connection between the driving ring 8 and the adjusting rod 10. When the block 14 slides toward the outside of the adjusting rod 10, the block 14 can cooperate with the slot.

[0060] A cam 131 is fixedly installed on the surface of the rotating rod 13, and the position of the cam 131 corresponds to that of the block 14. When the adjusting rod 10 and the adjusting rod 2 11 are in an axially sliding state, the block 14 cooperates with the slot, and when the adjusting rod 2 11 and the pressure rod 111 move radially, it is used to adjust the angle of the expansion portion 91. When the adjusting rod 10 and the adjusting rod 2 11 are in an axially fixed state, the block 14 is separated from the slot, and the movement of the adjusting rod 2 11 will drive the adjusting rod 10 to move together. At the same time, the trimming block 9 cannot rotate along the connection between the support 12 and the adjusting rod 10. This process is used to adjust the position of the extrusion portion 92.

[0061] A slide groove is provided on the inner side wall of the U-shaped member 121, a pressure rod 111 is provided on the side of the adjusting rod 11, a slider matching the slide groove is provided at the lower end of the pressure rod 111, and the upper end of the pressure rod 111 is fixedly connected to the upper end of the adjusting rod 11 through a block.

[0062] An adjusting ring 15 is rotatably installed inside the driving ring 8, and an adjusting groove 151 is provided on the inner wall of the adjusting ring 15. The distance between the two ends of the adjusting groove 151 and the axis of the welding seat 1 2 or the welding seat 2 3 is smaller than the distance between the middle position of the adjusting groove 151 and the axis of the welding seat 1 2 or the welding seat 2 3. A guide column 112 cooperating with the adjusting groove 151 is provided on the surface of the block.

[0063] A semicircular gear ring 16 is rotatably installed inside the driving ring 8, and the gear ring 16 is fixedly connected to the adjusting ring 15. A gear meshing with the gear ring 16 is installed inside the driving ring 8, and the gear is driven to rotate by a motor. The rotation of the adjusting ring 15 drives the adjusting rod 2 11 and the pressure rod 111 to move toward or away from the axis of the welding seat 1 2 or the welding seat 2 3.

[0064] When the angle of the expansion portion 91 is adjusted by radial movement of the pressure rod 111 in cooperation with the U-shaped piece 121, the adjusting rod 10 and the driving ring 8 are in a fixed state. When the radial position of the extrusion portion 92 is adjusted by cooperation of the adjusting rod 11 and the adjusting rod 10, the adjusting rod 10 and the support 12 are in a relatively fixed state. At this time, the angle of the expansion portion 91 no longer changes. The position of the trimming block 9 can be adjusted by radial movement of the adjusting rod 11.

[0065] The axial position of the drive ring 8 is adjusted by hydraulic rod 18, thereby adjusting the axial position of the expansion part 91, the extrusion part 92 and the welding block 21, so that the expansion part 91, the extrusion part 92 or the welding block 21 can correspond to the welding end of the copper tube, and the side slide grooves 81 corresponding to the side surfaces of the drive ring 8 inside the welding seat 1 2 and the welding seat 2 3 are combined to form an annular groove, so as to realize the continuous rotation of the drive ring 8 in the welding seat 1 2 and the welding seat 2 3. After welding is completed, the drive ring 8 is reset to the corresponding welding seat 1 2 or the welding seat 2 3 under the action of the gear cylinder 17.

[0066] A magnetic rod 19 is fixedly installed on the surface of the driving ring 8 close to the movable ring 6. The magnetic rod 19 is made of magnetic material. An electromagnetic ring 20 is provided on the surface of the movable ring 6 corresponding to the driving ring 8. The electromagnetic ring 20 is connected to a power supply. The position of the magnetic rod 19 is adjusted by using the driving ring 8 so that the magnetic rod 19 can correspond to the electromagnetic ring 20.

[0067] After the expansion is completed by using the welding end of the expansion part 91, the hydraulic rod 18 is used to control the drive ring 8 to move in the direction of the movable ring 6, so that the expansion part 91 is moved out of the copper tube, and then the reset trimming block 9 is adjusted to reversely control the movement of the drive ring 8. At this time, the electromagnetic ring 20 generates an adsorption force with the magnetic rod 19 in the energized state. While the axial position of the extrusion part 92 is adjusted by using the movement of the drive ring 8, the magnetic rod 19 cooperates with the electromagnetic ring 20 to drive the movable ring 6 to move together, and the movable ring 6 drives the copper tube inside it to move together until the copper tube is inserted into the expansion end of another section of the copper tube.

[0068] The U-shaped piece 121 is used to adjust the angle between the expansion part 91 and the axis of the welding seat 2 or the welding seat 3, so that the expansion part 91 can squeeze and expand the inner wall of the welding end of the copper tube, and the radial movement of the adjusting rod 10 is used to adjust the position of the extrusion part 92, and the extrusion part 92 is used to extrude the connection between the two sections of the copper tube, so that the expanded copper tube is wrapped on the surface of the other section of the copper tube.

[0069] The expansion part 91 is used to expand the welding end of one section of the copper tube as the driving ring 8 rotates, and the extrusion part 92 is used to insert and fix the welding end of the other section of the copper tube on the welding end of the expanded copper tube as the driving ring 8 rotates. The two copper tubes are welded together using the welding block 21. First, the flame nozzle in the welding block 21 is used to heat the connection between the two sections of the copper tubes, and then the heat on the surface of the copper tube is used to melt the welding fiber and weld it to the connection between the two sections of the copper tubes.

[0070] Working principle of air conditioner automated production welding equipment:

[0071] First, place the two sections of copper pipe fittings of the air conditioner between welding seat 1 2 and welding seat 2 3, and use hydraulic rod 1 4 to drive welding seat 1 2 and welding seat 2 3 to rotate closer to each other. The fixed ring 5 and movable ring 6 at both ends of the cylinder formed by the combination of welding seat 1 2 and welding seat 2 3 respectively support the two sections of copper pipes, use the fixing plate 51 inside the fixing ring 5 to fix one section of the copper pipe, and use the fixed wheel 61 inside the movable ring 6 to position and support the other section of the copper pipe.

[0072] At this time, a gap is reserved between the welding ends of the two sections of copper tubes. The hydraulic rod 2 18 is used to axially control the movement of the drive ring 8, and the drive ring 8 drives the trimming block 9 to move, so as to move the expansion part 91 to the welding end of the copper tube on one side of the fixed ring 5, and the gear ring 16 is used to drive the adjustment ring 15 to rotate, and the adjustment groove 151 and the guide column 112 are used to cooperate to drive the pressure rod 111 to move radially. At this time, the adjustment rod 2 11 and the adjustment rod 1 10 are in a relative sliding state. The movement of the pressure rod 111 is used to adjust the angle of the expansion part 91 so that the expansion part 91 can move axially to the inside of the welding end of the copper tube.

[0073] Through the axial movement of the driving ring 8, the expansion part 91 with the adjusted angle is entered into the welding end of the copper tube, and then the motor equipment is used to drive the gear part to rotate, and the driving ring 8 is driven to rotate through the meshing of the gear part and the gear cylinder 17, and the driving ring 8 drives the trimming block 9 to rotate together, and the trimming block 9 expands the welding end of the copper tube by driving the expansion part 91 to rotate, and the welding end is expanded into a V shape, and then through the axial movement of the driving ring 8, the expansion part 91 is moved out of the copper tube, and the adjustment ring 15 is continued to be rotated, and the rotation of the rotating rod 13 is coordinated to reset the angle of the trimming block 9, and the extrusion part 92 is axially adjusted to the position corresponding to the welding end of the copper tube. At this time, the axial movement of the driving ring 8 will cooperate with the electromagnetic ring 20 through the magnetic rod 19, and will drive the moving ring 6 to move, and the moving ring 6 drives the copper tube inside it to move toward another section of the copper tube, so that the welding end of the copper tube is inserted into the inside of the welding end of the above-mentioned expanded copper tube.

[0074] Then, the radial position of the extrusion part 92 is adjusted by rotating the adjustment ring 15, so that the extrusion part 92 squeezes the outer wall of the welding end of the expanded copper tube, and the gear cylinder 17 is used to drive the driving ring 8 to rotate, and the driving ring 8 is used to drive the extrusion part 92 to rotate. The extrusion part 92 squeezes the welding end of the above-mentioned copper tube by rotating, and wraps the expanded welding end of the copper tube around the outer surface of the welding end of another copper tube.

[0075] Then, the position of the welding block 21 is adjusted by axial movement of the driving ring 8 so that the welding block 21 corresponds to the welding point of the two sections of copper tubes. The welding point of the copper tube is first heated by the flame sprayed from the flame nozzle of the welding block 21, and then the welding fiber is fed into the welding point of the copper tube by the welding fiber feeding port. The heat on the surface of the copper tube is used to melt the welding fiber, and the melted welding fiber is welded to the connection of the copper tube, thus completing the welding of the copper tube.
