Description

Technical Field

[0001] The invention relates to the field of welding equipment, in particular to an air source heat pump shell processing and welding device. Background Art

[0002] In modern industrial production, the market demand for air source heat pumps, as an efficient, energy-saving and environmentally friendly heating and cooling equipment, is continuing to grow. As a key component, the shell of the air source heat pump must not only provide reliable physical protection for the internal compressor, heat exchanger and other core components to resist erosion and mechanical damage from the external environment, but also have good sealing properties to maintain a stable pressure environment inside the heat pump system and ensure efficient operation of the equipment. This places extremely high demands on the processing and welding quality of the air source heat pump shell.

[0003] The traditional air source heat pump shell processing and welding process faces many challenges. In the workpiece positioning and clamping process, manual operation or simple fixtures were often used in the past. The positioning accuracy was heavily dependent on the workers' experience, and it was difficult to ensure the consistency of each batch of products. The accumulation of positioning deviations between different batches can easily lead to inaccurate weld positions, thereby reducing product quality and increasing scrap rates. Moreover, manual clamping is inefficient and cannot meet the needs of large-scale production, which seriously restricts the improvement of production efficiency.

[0004] In terms of welding operation, traditional welding equipment lacks flexibility. Common fixed welding heads are difficult to perform all-round welding on complex shell welds, especially when facing the dead corners of the shell connection, effective welding is often impossible, making it difficult to ensure welding quality. At the same time, during the welding process, because the equipment is difficult to accurately control the welding angle and position, welding defects such as cold welding and leaking welding often occur, which not only affects the appearance quality of the product, but may also cause safety hazards during long-term use.

[0005] In addition, welding protection and cooling measures are also insufficient. The welding process will produce a large amount of harmful gases. If they cannot be discharged in time and effectively, it will not only pollute the production environment and endanger the health of workers, but also may have a negative impact on the welding quality. At the same time, if the high heat generated during the welding process cannot be dissipated in time, it is easy to cause local overheating and deformation of the shell, affecting the dimensional accuracy and overall performance of the product. Traditional cooling methods mostly use air cooling or simple water cooling, which has low cooling efficiency and cannot meet the needs of efficient and high-quality welding. Summary of the invention

[0006] In view of the shortcomings of the prior art, the present invention provides an air source heat pump casing processing and welding device, which solves the problems of difficult workpiece positioning, low clamping efficiency, poor flexibility of welding equipment, insufficient welding protection and cooling in traditional air source heat pump casing processing and welding, improves product quality and production efficiency, and reduces scrap rate and cost.

[0037] Working principle: First, start the first motor 12, and drive the rotating disk 13 to rotate through the first motor 12, driving one end of the two connecting rods 14 to move, and the other end of the connecting rod 14 will simultaneously push the abutment block 15 outward, and then the abutment block 15 will push the movable seat 3 outward, thereby driving the positioning plate 19 above the wedge-shaped connecting block 18 to move outward at the same time, and then place the two shell workpieces to be welded between the two positioning plates 19 of the discharge table 16 respectively, and then rotate the threaded adjustment shaft 21 to drive the clamping plate 20 to move inward to clamp the shell, thereby improving the stability of the subsequent welding. After completion, the first motor 12 drives the rotating disk 13 to reverse, and drives the two abutment blocks 15 to move inward at the same time through the connecting rod 14, while the movable seat 3 was previously pushed outward. The connecting frame 7 will be pushed outward through the push-pull rod 8 and the rotating frame 5 will rotate. The rotating rotating frame 5 will bend the spring plate 6 through the internal pressure roller 9, and the spring plate 6 will accumulate elastic potential energy when being bent. At the same time, during the bending process of the rotating frame 5 and the spring plate 6, the position of the pressure roller 9 will continue to change, so that the force arm of the bent spring plate 6 is also increasing, thereby compensating for the elastic force of the spring plate 6 that is constantly increasing with the increasing degree of bending. Similarly, when the spring plate 6 releases the elastic force and returns to the center, it will drive the rotating frame 5 to return to the center, and during the process of the spring plate 6 returning to the center, the force arm will continue to decrease, compensating for the elastic force of the spring plate 6 that is constantly decreasing with the decreasing degree of bending, so that the force applied to the push-pull rod 8 by the rotating frame 5 through the connecting frame 7 is maintained throughout the whole process. Maintain a certain uniformity. When the resistance block 15 releases the resistance and blocking effect on the movable seat 3, the pushing effect of the push-pull rod 8 is utilized to drive the two clamped shell workpieces to move inward at the same time, so that the two workpieces complete the butt joint of the weld. The force applied to the push-pull rod 8 by the connecting frame 7 is maintained at a certain uniformity throughout the process, so that the welds of the two workpieces always maintain a uniform butt joint force. While ensuring the stable butt joint of the weld, the shell will not be deformed due to excessive butt joint force, thereby improving the later welding quality. In addition, the positions of the two positioning tables 10 can be controlled to change by the two-way cylinder 11, thereby changing the support point positions of the two spring plates 6. When the support point positions are changed, the elastic force generated when rotating at the same angle will also change accordingly, It is convenient to adjust different welding joint forces and improve the scope of application. After the welding joint is completed, the X-axis motion module 24, the Y-axis motion module 25, the Z-axis motion module 23 and the laser welding gun 30 are started. The movable block 26 and the laser welding gun 30 are controlled by the three motion modules to move in three directions to achieve the welding of the workpiece. At the same time, the second motor 31 can also drive the driving gear 32 to rotate, drive the driven gear 33 and the cylinder 27 to rotate, thereby driving the welding angle of the laser welding gun 30 at the bottom to change, so as to achieve the welding of the dead angle at the connection of the workpiece and improve the welding quality. Finally, the third motor 47 is started, and the rotating drum 42 is driven to rotate by the third motor 47, which drives the bidirectional spiral groove 45 on the inner wall of the rotating drum 42 to rotate.The rotating bidirectional spiral groove 45 causes the round pin 46 to move inside it, thereby driving the piston rod 44 and the rubber piston 43 to perform linear motion in the air transfer chamber 34. The bidirectional spiral groove 45 is composed of two spiral grooves with opposite spiral directions and connected end to end. When the round pin 46 moves along the path of one of the spiral grooves to the end, it enters the initial position of the other spiral groove. This cycle is repeated, and the round pin 46 can perform reciprocating linear motion, thereby driving the piston rod 44 and the rubber piston 43 in the air transfer chamber 34. 4, and when the rubber piston 43 moves to the left, the air pressure in the left space of the air transfer chamber 34 increases, and the air pressure in the right space decreases. At this time, the external atmospheric pressure will open the one-way rubber valves 41 of the third air delivery pipe 39 and the fourth air delivery pipe 40, and the inert gas in the inert gas storage chamber 36 will be sucked into the right space of the air transfer chamber 34, and the gas in the left space will be discharged into the waste gas collection chamber 35. Similarly, when the rubber piston 43 moves to the right, the one-way rubber valves of the first air delivery pipe 37 and the second air delivery pipe 38 will be opened. The glue valve 41 will be opened, and the harmful gas generated by welding will be sucked into the left space of the gas transfer chamber 34 through the hollow bent air inlet pipe 28 and the first air delivery pipe 37, and the inert gas will be discharged to the periphery of the laser welding gun 30 through the second air delivery pipe 38 and the hollow bent exhaust pipe 29, so as to achieve protection during welding. At the same time, when the rotating drum 42 rotates, it will also drive the driving wheel 51 to rotate, and through the transmission of the transmission belt 53, it will drive the driven wheel 52 and the short shaft 49 to rotate, and the short shaft 49 will drive the cross brush plate 50 to rotate at high speed. At this time, clean water is introduced into the water tank 48 through the water inlet pipe 54, and the high-speed rotating cross brush plate 50 breaks the clean water into small water droplets. These small water droplets will enter the second gas pipe 38, mix with the inert gas to form a high-speed water vapor fluid, and be discharged to the surrounding of the laser welding gun 30 together with the inert gas. When the water vapor fluid is discharged, it will evaporate rapidly after being heated. The principle of evaporation and heat absorption is used to achieve rapid cooling and cooling during the welding process. After welding is completed, the clamping plate 20 and the positioning plate 19 are loosened, and the workpiece can be removed.
