Description

Technical Field

[0001] The present invention relates to the technical field of condenser welding, and particularly relates to a welding device for aluminum condensers. Background Art

[0002] Aluminum materials are widely used in condenser manufacturing due to their excellent thermal conductivity and light weight. A condenser is a heat exchange device that cools and condenses high-temperature and high-pressure gaseous refrigerant discharged from a compressor into a liquid state. Its core function is to release heat to a cooling medium, which is a key link in completing the refrigeration cycle.

[0003] Welding processes are usually required during the manufacturing of condensers. Its structure consists of components such as pipes, fins, and a housing. Welding is used to connect metal components to ensure sealing performance and structural strength. During the welding process, precise alignment of components needs to be ensured through positioning. For example, when welding a small flange and a connecting pipe of an aluminum alloy condenser, the components need to be positioned first before welding to control deformation.

[0004] A patent document with the publication number CN118616837B discloses a welding device and a welding method for an automotive air conditioner condenser pipe joint, including a workbench, support leg rods, a partition board, and an adjustment mechanism. A long strip board is fixedly installed at the center of the top of the workbench. Strip-shaped openings are symmetrically formed along the length direction of the long strip board on the workbench. The two ends of the top of the adjustment mechanism penetrate through the two strip-shaped openings. Welding mechanisms are fixedly installed on the opposite sides of the two ends of the top of the adjustment mechanism. An adjustment cylinder is used to move and adjust one of the moving modules, and the other moving module is driven to move synchronously through a linkage module, thereby realizing synchronous adjustment of the distance between the welding mechanisms at the top of the support columns for welding operations on the pipe joint.

[0005] However, the following problems still exist in this solution. During welding, a clamping device is needed to clamp and position the components to be welded. However, the condenser is a special-shaped part with an irregular shape, and most of the components of the condenser are also special-shaped parts with irregular shapes. It is inconvenient to clamp and fix them using a conventional clamping device, resulting in incorrect dimensions of the condenser due to position deviation during the welding of special-shaped parts, affecting the welding quality of the condenser. In addition, it is rather troublesome to use clamping blocks of different shapes for clamping, resulting in low welding efficiency of the condenser. And during the welding process, a certain degree of thermal expansion will occur at the welding site, and the expansion thrust causes welding deformation of the welded components, affecting the welding effect. Also, there are small particle residues such as welding slag in the welding environment. If welding slag impurities adhere to the bottom surface of the workpiece, it will affect the clamping and welding accuracy due to uneven placement on the workbench. Summary of the Invention

[0006] The present invention provides a welding device for aluminum condensers, aiming to solve the problems in the related technology that it is inconvenient to clamp special-shaped components and the welding slag adhering to the condenser will affect the welding accuracy.

After the slider is separated from the workpiece, the rotating part drives the slider to rotate to a vertical state, and the pushing part cooperates with the push plate to drive the wiping layer to cooperate with the side of the workpiece. At the same time, the push plate drives multiple push rods to move toward the workpiece, clamping both sides of the workpiece through the wiping layer to fix the workpiece.

[0008] The effect is that when the workpiece is placed on the workbench, the slider is in a horizontal state, the wiping layer is in contact with the bottom of the workpiece, and the driving member drives the two sliders to move synchronously in opposite directions. The slider wipes and cleans the bottom of the workpiece through the wiping layer when moving. When the slider moves to separate from the workpiece, the slider rotates to a vertical state under the action of the rotating member, and then the push member drives the slider to move close to the side of the workpiece. At the same time, the push plate moves relative to the slider, so that the pressure of the hydraulic oil in the oil chamber increases, driving the push rod to move toward the workpiece. The push rod clamps the workpiece through the wiping layer, and the pressure of the hydraulic oil is evenly distributed to each push rod, so that the clamping force applied by the push rod to the workpiece is the same. On the one hand, special-shaped parts can be fixed, and on the other hand, the force at each location on the part is guaranteed to be the same during welding, so as to avoid the phenomenon that the parts are offset due to excessive local force or thermal expansion caused by welding during welding, prevent welding deformation, and thus improve welding accuracy.

[0040] like Figures 1 to 10 As shown, the aluminum condenser welding device of the present invention includes a workbench 1, on which are arranged: a slider 2, a driving member 3, and a push member 4. There are two sliders 2, and the two sliders 2 are arranged to slide left and right on the workbench 1. The driving member 3 is connected to the slider 2 to drive the slider 2 to slide left and right. At the same time, the slider 2 is rotatably connected to the driving member 3. A rotating member 21 is arranged at the connection between the slider 2 and the driving member 3. The rotating member 21 is arranged as a torsion spring. The rotating member 21 is respectively connected to the slider 2 and the driving member 3. The rotating member 21 is used to drive the slider 2 to rotate to a vertical state. A wiping layer 5 is arranged on the slider 2. There are two push members 4, and the two push members 4 are respectively arranged on both sides of the workpiece 01 and arranged in the horizontal direction. The push member 4 is arranged as a cylinder.

[0041] After the workpiece 01 is placed on the workbench 1, the workpiece 01 is located above the slider 2, at which time the slider 2 is in a horizontal state, the wiping layer 5 is located above the slider 2, and the wiping layer 5 abuts against the bottom of the workpiece 01, and then the driving member 3 drives the slider 2 to move, and the movement of the slider 2 drives the wiping layer 5 to move, and the bottom of the workpiece 01 is wiped and cleaned. After the slider 2 moves to separate from the workpiece 01, the rotating member 21 drives the slider 2 to rotate to a vertical state, at which time the wiping layer 5 corresponds to the side of the workpiece 01, and then the output end of the push member 4 cooperates with the side of the slider 2 away from the wiping layer 5, and pushes the slider 2 to move toward the workpiece 01 until the slider 2 abuts against the workpiece 01 through the wiping layer 5, and the two sliders 2 cooperate with the two sides of the workpiece 01 respectively to clamp and fix the workpiece 01.

[0042] Reference Figure 4 , Figure 6, Figure 7 , a plurality of push rods 6 are slidably arranged on the slider 2, and the push rods 6 are arranged in a direction perpendicular to the slider 2, and the push rods 6 are in contact with the inner side of the wiping layer 5. An oil chamber 22 is provided in the slider 2, and the oil chamber 22 is filled with hydraulic oil. The end of the push rod 6 away from the wiping layer 5 extends into the oil chamber 22, and the position of the push rod 6 can be adjusted by adjusting the pressure of the hydraulic oil in the oil chamber 22. A push plate 23 is provided on the side of the slider 2 away from the wiping layer 5, and the push plate 23 is slidably assembled on the slider 2, and the sliding direction of the push plate 23 is the same as the sliding direction of the push rod 6. The side of the push plate 23 close to the slider 2 is the oil chamber 22, that is, the push plate 23 is in contact with the hydraulic oil in the oil chamber 22. The oil pressure of the hydraulic oil can be adjusted by moving the push plate 23, and then the position of the push rod 6 can be adjusted. The wiping layer 5 is set as a sponge or a metal rubber with a cleaning function.

[0043] Initially, the workpiece 01 is placed on the workbench 1, the slider 2 is located below the workpiece 01, the two sliders 2 are located in the middle of the workpiece 01, and the sliders 2 are in a horizontal state. The wiping layer 5 is located above the sliders 2 and contacts with the bottom of the workpiece 01. The driving member 3 drives the two sliders 2 to move synchronously, and the two sliders 2 move toward the two sides of the workpiece 01 respectively. When moving, the sliders 2 wipe and clean the bottom of the workpiece 01 through the wiping layer 5. When the slider 2 moves to separate from the workpiece 01, the rotating member 21 drives the slider 2 to rotate to a vertical state, and drives the wiping layer 5 to rotate to correspond to the side of the workpiece 01. At this time, the slider 2 is located at the output end of the push member 4, and the output end of the push member 4 cooperates with the push plate 23, and drives the slider 2 to move close to the workpiece 01, and drives the wiping layer 5 to abut against the side of the workpiece 01. At the same time, when the push member 4 drives the slider 2 to move through the push plate 23, the push plate 23 moves relative to the slider 2, squeezes the hydraulic oil in the oil chamber 22, and drives multiple push rods 6 to move toward the direction of the workpiece 01. The push rods 6 apply a clamping force to the workpiece 01 through the wiping layer 5 to fix the workpiece 01. The push rods 6 move under the pressure of the hydraulic oil, and each push rod 6 bears the same pressure. When it comes to special-shaped parts, multiple push rods 6 can be used to cooperate with various positions on the parts respectively, and each push rod 6 applies the same force on the parts to improve the stability when clamping the workpiece 01.

[0044] Reference Figure 6 , Figure 7 A plurality of sliding sleeves 24 are arranged on the slider 2. The plurality of sliding sleeves 24 are arranged one by one with the plurality of ejector rods 6. The end of the sliding sleeve 24 is arranged in the oil chamber 22. The ejector rod 6 is slidably assembled in the sliding sleeve 24. The end of the ejector rod 6 close to the oil chamber 22 is arranged at intervals from the end of the sliding sleeve 24. When the push plate 23 moves to increase the oil pressure in the oil chamber 22, the oil pressure of the hydraulic oil in the sliding sleeve 24 increases at the same time, so as to drive the ejector rod 6 in the sliding sleeve 24 to move, and adjust the position of the ejector rod 6.

[0045] Reference Figure 6 , Figure 7 The two ends of the push rod 6 are respectively provided with a sealing part 61 and a contact part 62. The sealing part 61 is provided at one end of the push rod 6 close to the oil chamber 22. The sealing part 61 is slidably provided in the sliding sleeve 24, and the sealing part 61 is slidably contacted with the inner wall of the sliding sleeve 24. The contact part 62 is provided on the side of the push rod 6 close to the wiping layer 5, and the contact part 62 is matched with the inner side of the wiping layer 5. When the oil pressure in the oil chamber 22 increases, the sealing part 61 is driven to move in the sliding sleeve 24, and the sealing part 61 drives the push rod 6 and the contact part 62 to move, thereby fixing the workpiece 01.

[0046] Reference Figure 2 , Figure 5 , Figure 7 A plurality of protrusions 7 are arranged on the workbench 1, and the plurality of protrusions 7 are arranged along the sliding direction of the slider 2, and the protrusions of the protrusions 7 are arranged toward the slider 2. A mounting frame 8 and a push rod 81 are slidably arranged on the slider 2, and the mounting frame 8 is arranged on the side of the slider 2 close to the wiping layer 5. The mounting frame 8 is slidably arranged on the slider 2, and the sliding direction of the mounting frame 8 is perpendicular to the sliding direction of the slider 2. The wiping layer 5 is arranged on the mounting frame 8, and one end of the push rod 81 is connected to the mounting frame 8, and the other end extends to the side of the slider 2, and the push rod 81 corresponds to the protrusion 7. An elastic member 82 is arranged on the mounting frame 8, and the elastic member 82 is arranged as a spring. The elastic member 82 is respectively connected to the mounting frame 8 and the slider 2, and the elastic member 82 is used to drive the push rod 81 to move in the direction toward the protrusion 7.

[0047] When the slider 2 is in a horizontal state, the end of the push rod 81 away from the slider 2 is in the same straight line as the plurality of protrusions 7. When the slider 2 moves, the push rod 81 is driven to pass through the plurality of protrusions 7 in sequence. At the same time, under the action of the elastic member 82, the push rod 81 and the protrusion 7 are always kept in contact. Under the action of the push rod 81 and the elastic member 82, the mounting frame 8 is driven to move back and forth, thereby driving the wiping layer 5 to move back and forth with the slider 2 while wiping the workpiece 01, thereby improving the wiping effect on the workpiece 01.

[0048] Reference Figure 5 , two sets of mounting frames 8 and elastic members 82 are provided on each slider 2, the two sets of mounting frames 8 are arranged in parallel and spaced apart, and each mounting frame 8 is provided with a wiping layer 5. An intermediate wheel 83 is provided between the two sets of mounting frames 8, the intermediate wheel 83 is rotatably matched with the slider 2, and the side of the intermediate wheel 83 abuts against the side of the two sets of mounting frames 8 at the same time. A push rod 81 is connected to one of the mounting frames 8.

[0049] When the installation frame 8 moves, due to the static friction between the intermediate wheel 83 and the installation frame 8, the two installation frames 8 are driven to move synchronously in opposite directions, thereby realizing the adjustment of the positions of the two installation frames 8 at the same time. In other embodiments, the intermediate wheel 83 can be set as a gear, and a tooth groove can be opened on the side surface of the installation frame 8. The tooth groove is arranged along the sliding direction of the installation frame 8, and the gear meshes with the tooth groove. When the installation frame 8 moves, the gear drives the two installation frames 8 to move synchronously through the tooth groove, and the positions of the two installation frames 8 are adjusted at the same time.

[0050] Referring to Figure 6 、 Figure 7 , a through hole 84 is opened on the installation frame 8. The through hole 84 is arranged along the sliding direction of the installation frame 8. The top block penetrates through the through hole 84, that is, both ends of the ejector rod 6 are respectively arranged on both sides of the through hole 84. A relief groove 51 is opened on the inner side of the wiping layer 5, and the abutting portion 62 is located in the relief groove 51.

[0051] When the installation frame 8 moves relative to the slider 2, the installation frame 8 moves relative to the ejector rod 6 through the through hole 84. At the same time, the abutting portion 62 moves in the relief groove 51, reducing the phenomenon that the ejector rod 6 interferes with the movement of the installation frame 8.

[0052] Referring to Figure 2 、 Figure 3 、 Figure 4 , the driving member 3 is arranged below the slider 2. The driving member 3 includes: a motor 31, a telescopic rod 32, and a gear 33. The lower end of the telescopic rod 32 is rotatably arranged on the workbench 1. There are two groups of telescopic rods 32 and gears 33. The gear 33 is arranged at the lower end of the telescopic rod 32. The gears 33 on the two telescopic rods 32 mesh with each other. The telescopic rod 32 is rotatably connected to the slider 2. The telescopic rod 32 is set as a rod-shaped structure that can be telescopically adjusted to its own length. The motor 31 is arranged on the workbench 1, and the output shaft of the motor 31 is coaxially connected to one of the gears 33.

[0053] The motor 31 drives the gear 33 to rotate. The rotation of the gear 33 drives the telescopic rod 32 to rotate. And under the action of the two gears 33, the two telescopic rods 32 are driven to rotate in opposite directions. When the telescopic rod 32 rotates, it drives the two sliders 2 to slide in opposite directions. When the slider 2 slides, the telescopic rod 32 expands and contracts accordingly, so as to reduce the phenomenon that the telescopic rod 32 interferes with the movement of the slider 2.

[0054] After the slider 2 rotates to the vertical state, the motor 31 stops working. The output end of the pusher 4 cooperates with the push plate 23 to drive the slider 2 to move closer to the workpiece 01 and clamp the workpiece 01.

The first guide groove 111 communicates with the chute 11. The first guide groove 111 is located above the chute 11 and is arranged at one end of the chute 11 close to the pushing member 4.

[0056] When the slider 2 is in a horizontal state, both the first guide block 25 and the second guide block 26 are located in the chute 11. As the slider 2 moves, both the first guide block 25 and the second guide block 26 move in the chute 11. After the slider 2 moves to be separated from the workpiece 01, the second guide block 26 moves to the first guide groove 111. The rotating member 21 drives the slider 2 to rotate, so that the second guide block 26 rotates through the first guide groove 111 to be separated from the chute 11 until the slider 2 rotates to a vertical state.

[0057] Refer to Figure 10 , a second guide groove 112 is also provided on the workbench 1. The second guide groove 112 has the same structure as the first guide groove 111. The second guide groove 112 is also located above the chute 11 and communicates with the chute 11. The second guide groove 112 is arranged at one end of the chute 11 away from the pushing member 4.

[0058] After the workpiece 01 is processed, the motor 31 drives the slider 2 to move to the initial position through the telescopic rod 32. At this time, the slider 2 is in a vertical state. The slider 2 can be rotated to drive the second guide block 26 to rotate through the second guide groove 112 and back into the chute 11 again, so that the slider 2 is in a horizontal state for cleaning the workpiece 01 again.

The levers 92 are rotatably installed on the workbench 1. The rotation axis of the lever 92 corresponds to the middle of the support rod 93. A torsion spring is provided at the connection between the lever 92 and the workbench 1. The torsion spring drives the two levers 92 to rotate in the direction towards each other. The support rod 93 is arranged perpendicular to the rotation plane of the lever 92. A pressing plate 931 is provided on the support rod 93. The pressing plate 931 is arranged between the two levers 92. Under the action of the torsion spring, the lever 92 and the pressing plate 931 are kept in a butting state.

[0060] In the initial state, both sliders 2 are arranged close to the lever 92, and the sliders 2 are in a vertical state. When placing the workpiece 01, the workpiece 01 is placed on the support rod 93, driving the support rod 93 to move downward, and the support rod 93 drives the pressure plate 931 to move downward and press the lever 92. The two levers 92 rotate in a direction away from each other, and the lever 92 abuts against the guide block 26 to drive the slider 2 to rotate to the inclined state. After the slider 2 rotates to the inclined state, the workpiece 01 continues to be placed, and the bottom of the workpiece 01 abuts against the inclined slider 2. When the support rod 93 abuts against the workbench 1, the workpiece 01 is placed on the workbench 1, and the workpiece 01 is supported by the support rod 93. At the same time, the workpiece 01 drives the slider 2 to rotate to the horizontal state, and the slider 2 drives the guide block 26 to rotate into the slide groove 11 through the guide groove 2 112 during the process of rotating to the horizontal state.

[0061] Reference Figure 2 The workbench 1 includes a fixed part 12 and a movable part 13. The movable part 13 is slidably assembled on the fixed part 12. The push piece 4, the slider 2, the support rod 93, and the lever 92 are all installed on the movable part 13. An adjusting member 121 is provided on the fixed part 12. The adjusting member 121 is set as a cylinder. The adjusting member 121 is set on the fixed part 12. The output end of the adjusting member 121 is connected to the movable part 13 to drive the movable part 13 to move up and down. Initially, the movable part 13 is flush with the fixed part 12. When the rest of the workpiece 01 needs to be welded, the adjusting member 121 drives the movable part 13 to move upward, so that the workpiece 01 is away from the fixed part 12, so as to leave a space for welding below the workpiece 01 for subsequent welding.

[0062] Reference Figure 1 A plurality of clamping assemblies 14 are arranged on the workbench 1, and the plurality of clamping assemblies 14 are arranged around the workpiece 01. The clamping assemblies 14 include a mounting rod 141, a pushing member 142, and a clamping plate 143. The mounting rod 141 is connected to the workbench 1, and the pushing member 142 is arranged at the end of the mounting rod 141 away from the workbench 1. The pushing member 142 is arranged as a cylinder, and the clamping plate 143 is arranged at the output end of the pushing member 142. The pushing members 142 in the plurality of clamping assemblies 14 are all arranged in the direction of the workpiece 01. After the workpiece 01 is placed on the workbench 1, the pushing member 142 drives the clamping plate 143 to move to abut against different positions on the workpiece 01, so as to assist in clamping and fixing the workpiece 01.

[0063] Reference Figure 1, the mounting rod 141 includes two rotatably engaged connecting portions 144. The two connecting portions 144 are rotatably connected by a hinge, and a bolt is provided between the two connecting portions 144. The bolt passes through the two connecting portions 144 and cooperates with a nut to fix the two connecting portions 144 in a vertical state. One of the connecting portions 144 is fixedly connected to the workbench 1, and the other connecting portion 144 is connected to the pushing member 142. Before placing the workpiece 01, the bolt is removed and the connecting portion 144 is rotated. After the workpiece 01 is placed at the designated position, the connecting portion 144 is rotated to the vertical state, driving the pushing member 142 that cooperates with the top of the workpiece 01 to rotate above the workpiece 01, and then it is fixed again by the bolt and nut. By providing that the mounting rod 141 includes two rotatably engaged connecting portions 144, the phenomenon that the pushing member 142 that cooperates with the top of the workpiece 01 interferes with the placement of the workpiece 01 is reduced, and the welding efficiency is improved.

[0064] The implementation principle of the present invention is as follows: The workpiece 01 is placed on the support rod 93 until the support rod 93 is driven to abut against the workbench 1. At the same time, under the action of the support rod 93, the workpiece 01 and the dial rod 92, the slider 2 is driven to rotate to the horizontal state, and both the guide block one 25 and the guide block two 26 are located in the chute 11. At this time, the wiping layer 5 abuts against the bottom of the workpiece 01.

[0065] The motor 31 drives the two sliders 2 to move simultaneously in opposite directions through the gear 33 and the telescopic rod 32. The movement of the slider 2 drives the wiping layer 5 to move to clean the workpiece 01. At the same time, the wiping layer 5 reciprocates under the action of the convex block 7 and the push rod 81 to wipe and clean the bottom of the workpiece 01.

[0066] After the slider 2 moves away from the workpiece 01, the cleaning of the bottom of the workpiece 01 is completed. At this time, the guide block two 26 moves to the guide groove one 111, and the rotating member 21 drives the slider 2 to rotate to the vertical state. The push plate 23 corresponds to the output end of the pushing member 4. The pushing member 4 drives the slider 2 to move towards the workpiece 01 through the push plate 23. After the wiping layer 5 abuts against the workpiece 01, the push plate 23 moves relative to the slider 2, squeezing the hydraulic oil in the oil cavity 22, driving the plurality of ejector rods 6 to move synchronously towards the workpiece 01. The ejector rods 6 clamp the workpiece 01 through the wiping layer 5, and the changing oil pressure in the oil cavity 22 is evenly distributed on each ejector rod 6. The plurality of ejector rods 6 can abut against various positions on the special-shaped component, and the force exerted by the ejector rods 6 on the component is the same, improving the clamping stability of the component.

[0067] When the slider 2 moves, it cleans the bottom of the workpiece 01 through the wiping layer 5. After moving to the side of the workpiece 01, it clamps the components through multiple ejector rods 6 to fix the special-shaped components, and at the same time can clean the bottom of the workpiece 01. In addition, the forces applied by the multiple ejector rods 6 on the components are the same, which can avoid the phenomenon that local components are overstressed or the components are displaced due to thermal expansion caused by welding during welding, prevent welding deformation, and improve welding accuracy.

[0068] Although the embodiments of the present invention have been shown and described above, it can be understood that the above embodiments are exemplary and should not be construed as limiting the present invention. Those of ordinary skill in the art can make changes, modifications, substitutions, and variations to the above embodiments within the scope of the present invention.
