Description

Technical Field

[0001] The invention relates to the technical field of tooling equipment, and in particular to a gas shielded welding rapid positioning tool for an air conditioner liquid reservoir. Background Art

[0002] The air conditioning receiver is an important component in the air conditioning system. Its main function is to store refrigerant and provide it when the system needs it. In order to ensure the quality and performance of the receiver, the welding process in its manufacturing process is particularly important. Gas shielded arc welding (GMAW) is a common welding method suitable for high-quality welding of thin-sheet metal parts, including stainless steel, aluminum and other materials. For components such as air conditioning receivers that require good sealing and complex structures, the use of gas shielded arc welding technology can effectively improve the reliability and service life of the product.

[0003] According to the patent with the patent authorization announcement number CN218638951U, a welding device for the end cover of a gas storage tank is disclosed, including a base, a stop mechanism, an operating station and a welding mechanism. A mounting base plate is arranged above the base, and a rotating mechanism and a stop mechanism are arranged on the upper surface of the base. The rotating mechanism is used to drive the mounting base plate to rotate. The welding device positions the end cover bracket by the positioning column and the positioning protrusion on the push plate, and the positioning effect of the end cover bracket is achieved under the elastic action of the spring; however, the welding device still has certain limitations when used. Since an open baffle and a "V"-shaped support plate are used to position different types of liquid storage tanks, although the versatility is improved, the position of the baffle and the support plate needs to be adjusted each time the product model is changed, which increases the operation steps and reduces the production efficiency. In addition, during the welding process, the operator needs to hold the welding gun and manually turn the liquid storage tank to perform rotation welding, resulting in the welding effect relying on the skill level of the operator.

The inner wall of the mounting ring 85 is circumferentially fixed with electric slide rails 86 of the same number as the fixed rod 81. The mounting ring 85 is installed on the fixed rod 81 through the electric slide rails 86. The fixed rod 81 is respectively located inside the corresponding electric slide rails 86 and slides together. The driving member 9 is arranged between the feeding barrel 4 and the rotating ring 7. The driving member 9 is used to drive the rotating ring 7 to rotate, so that the rotating ring 7 and the liquid storage tank material clamped in the clamping mechanism 8 rotate, and cooperate with the gas shielded welding gun 100 to perform rotation welding operation on the liquid storage tank and the top cover material placed therein.

[0030] like Figure 3-Figure 5As shown, the clamping curved plate 83 is provided with slots, and the bottom of the slots of the clamping curved plate 83 is rotatably installed with a positioning plate 87, which is located on one side of the inner wall of the clamping curved plate 83, and a torsion spring 88 is provided between the rotating shafts of the clamping curved plate 83 and the positioning plate 87. The positioning plate 87 tilts upward under the action of the torsion spring 88, and the positioning plate 87 is used to upwardly support and support the tank material between the clamping curved plates 83. When the first multi-stage cylinder 61 lifts the tank material through the placement plate 62 and passes through the positioning plate 87 and detaches, the positioning plates 87 at multiple circumferential positions are reset and tilted upward to support and position the tank material under the action of the torsion spring 88, so as to avoid the tank material from sinking during the welding process and improve the stability of the tank material in the positioning welding between the clamping curved plates 83.

[0032] When the positioning fixture is used to perform positioning welding on the air conditioner reservoir, the baffle 41 at the feed port of the feed barrel 4 is opened, and the conveying module 300 is controlled by the program timing to automatically feed the reservoir tank material to be welded, so that the conveying module 300 intermittently transfers the reservoir tank material to be welded to the mounting plate 3 in a flush manner. When the tank material is transmitted to the push plate aligned with the first electric push rod 5, the conveying module 300 is closed, and the first electric push rod 5 is enabled. The first electric push rod 5 pushes the tank material smoothly into the feed barrel 4 through the push plate at the end of the push rod. When the tank material slides onto the placement plate 62 supported by the first multi-stage cylinder 61, the first electric push rod 5 is reset and retracted to prepare to push the next tank material of the conveying module 300, and then the first multi-stage cylinder 61 is activated, and the first multi-stage cylinder 61 pushes the tank material on the placement plate 62 to move upward in the feed barrel 4. As the telescopic rod of the first multi-stage cylinder 61 continues to extend, the placement plate 62 and the tank material thereon are lifted to a position equal to the top of the rotating ring 7. At this time, the clamping mechanism 8 on the rotating ring 7 begins to work, and the ring is installed. The plurality of electric slide rails 86 in the circumferential direction 85 synchronously drive the corresponding fixing rods 81 and the clamping curved plates 83 to open outwards, and the tank material placed on the placing plate 62 is lifted upward to between the clamping curved plates 83 under the guidance of the guide curved plates 84. When the first multi-stage cylinder 61 continues to lift the tank material between the clamping curved plates 83 through the placing plate 62, the tank material will contact and squeeze the positioning plate 87 during the upward movement, and the positioning plate 87 rotates and compresses the torsion spring 88 until the first multi-stage cylinder 61 moves the welding position of the tank material upward and aligns it with the gas shielded welding gun 100. When the tank material is positioned, the upwardly moved tank material is separated from the positioning plate 87, and the positioning plate 87 is reset and positioned and supported at the bottom of the tank material under the action of the torsion spring 88, so that the tank material is supported and positioned in the vertical direction, and at the same time, the circumferential multiple electric slide rails 86 synchronously drive the corresponding fixed rods 81 and the clamping curved plates 83 to retract inwardly, and the circumferential multiple clamping curved plates 83 synchronously apply clamping force inwardly to the outer wall of the tank material, so that the tank material is clamped and positioned in the horizontal direction, thereby realizing stable and rapid positioning of the tank material, and preparing for subsequent welding.

The arc plate 132 is connected to the connecting frame 131 through the second screw rod 133. The second screw rod 133 and the corresponding connecting frame 131 are threadedly adapted. The center of the two arc plates 132 is consistent with the center of the clamping curved plate 83. The second screw rod 133 is turned to adjust the positioning position of the arc plate 132, so that the arc plate 132 can align with the tank material and accurately position the top cover material, thereby avoiding the top cover material and the tank material from offsetting in the pushing direction.

[0038] Before welding the air conditioner reservoir, first open the door panel 106 of the side wall of the storage cover barrel 101, and stack the top cover material that is suitable for the tank material in the storage cover barrel 101 in advance, and then screw the first screw rod 103 to make the limiting arc plate 102 adapt to and limit the top cover material of the current size to avoid the top cover material stacked in the storage cover barrel 101 from shifting or tipping over. When the top cover material needs to be taken for welding, the second multi-stage cylinder 104 is activated. The push plate on the telescopic rod of the second multi-stage cylinder 104 will push the bottom top cover material upward, and make the top cover materials stacked in the storage cover barrel 101 rise in turn and emerge from the outlet of the top plate 105 of the storage cover barrel 101. When a top cover material on the top layer contacts the electric suction cup 113, the second multi-stage cylinder 104 is activated. The cylinder 104 is closed, and the electric suction cup 113 is activated to absorb the top cover material in contact.

As the top cover material adsorbed by the electric suction cup 113 slides in from the top of the stably clamped tank material, when the top cover material contacts the arc plate 132, the welding ends of the top cover material and the tank material are completely aligned, and then the second electric push rod 111 is closed, and then the first motor 92 and the second motor 114 are synchronously enabled. The first motor 92 drives the rotating ring 7 to rotate through the engagement of the gear 93 and the gear ring 91, and then drives the tank material in the clamping mechanism 8 to rotate synchronously through the rotating ring 7. At the same time, the second motor 114 also synchronously drives the top cover material to rotate at the same angular velocity to maintain the relative static state between the top cover material and the tank material. Finally, the gas shielded welding gun 100 on the support plate 200 continuously welds the welding surfaces of the top cover material and the tank body material according to the preset path, thereby completing the firm combination of the liquid reservoir tank body and the top cover. After the top cover material and the tank body material of the liquid reservoir are welded and stabilized, the electric suction cup 113 is closed and detached from the top cover material, and then the electric suction cup 113 on the mounting frame 112 is driven by the second electric push rod 111 to reset to the storage cover tube 101 and prepare to absorb the next top cover material, and the first multi-stage cylinder 61 is activated again to drive the placement plate 62 to move upward. When the placement plate 62 supports the welded liquid reservoir product again, the clamping mechanism 8 releases the clamping limit of the liquid reservoir, and the first multi-stage cylinder 61 continues to drive the welded liquid reservoir product to complete the discharge.
