Description

Technical Field

[0001] The invention relates to the technical field of welding forming equipment, in particular to a rapid welding forming equipment for a fin tube radiator. Background Art

[0002] Fin tube radiators are welded parts and are often used in the cooling system of automobile engines as important structural parts of heat exchange equipment.

[0003] When the fin tube radiator works, it effectively transfers the heat generated by the engine to the surrounding air. Therefore, the welding quality of the fin tube radiator is crucial to maintaining the normal operation of the engine.

[0004] The fin tube radiator is mainly composed of multiple fin tubes and connecting elbows outside the end plate frames at both ends, which are fixed together by welding and then fixed to the end plate frames. The welding method often adopts a elbow and fin tube welding structure disclosed in the patent document with patent application number CN201922261304.4. The ends of the elbow joint and the fin tube joint are provided with welding slopes, so that a V-shaped groove is formed after the elbow and the fin tube are butt-jointed. After the elbow and the fin tube are butt-jointed, they are manually welded one by one in the V-shaped groove.

[0005] However, the above structure has the following problems when using the existing manual welding method:

[0006] First, since there are multiple fin tubes in the fin tube radiator, manual welding requires welding at multiple locations, resulting in low overall welding efficiency and greater difficulty in manual welding operations.

[0007] Second, before welding, the ends of the multiple fin tubes at both ends of the fin tube radiator need to be fixed to the end plate structures at both ends. When manual welding is used, it is necessary to cooperate with the clamp to complete the positioning to ensure the positioning accuracy during welding. In the process of welding one by one, it is easy to cause abnormal collision and displacement of the fin tubes, resulting in reduced welding quality and affecting the molding quality of the entire radiator.

[0008] Based on this, the present invention optimizes the welding equipment in the welding forming process of the fin tube components in the fin tube radiator, and specially designs a fin tube radiator rapid welding forming equipment to better solve the problems existing in the prior art.

[0048] The following is a detailed description of the embodiments of the technical solution of the present invention in conjunction with the accompanying drawings. The following embodiments are only used to more clearly illustrate the technical solution of the present invention, and are therefore only used as examples, and cannot be used to limit the scope of protection of the present invention. Figure 1-Figure 11 as shown in .

[0049] Embodiment 1: A fin tube radiator rapid welding forming equipment comprises a main body positioning unit 1 horizontally arranged on the ground, the upper part of the main body positioning unit 1 is used to position the vertical plates 201 on both sides of the radiator 2 to be welded, front and rear positioning units 3 are symmetrically installed on the ground on both sides of the main body positioning unit 1, and a lifting positioning unit 4 is respectively installed on the top of each of the front and rear positioning units 3, and a fin tube butt welding forming unit is respectively installed at the inner end of each of the lifting positioning units 4, and the fin tube butt welding forming unit is used to synchronously complete the annular welding of the two ends of the U-shaped bend 203 and the butt joints of the ends of the two adjacent fin tubes 202 at their corresponding positions, and each of the front and rear positioning units 3 is connected to the corresponding side of the main body positioning unit 1 through a translation component.

[0050] It should be noted that the radiator 2 is a fin tube radiator in the prior art, and its structure mainly includes two vertical plates 201 arranged at a relative interval, and a plurality of fin tubes 202 are horizontally spaced between the two vertical plates 201. Both ends of each fin tube 202 pass through the outside of the corresponding vertical plate 201, and the ends of two adjacent fin tubes 202 are connected by a U-shaped bend 203. The annular joints between the U-shaped bend 203 and the corresponding fin tube 202 are fixed and formed by annular welding.

[0051] The fin tube radiator 2 is a conventional structure in an automobile, and its main body is formed by welding. The ends of the fin tubes 202, which are the core heat dissipation components, are connected in series by relying on the U-shaped bends 203 at the ends. Therefore, the welding of the butt joints between the ends of the fin tubes 202 and the U-shaped bends 203 is crucial. Therefore, the present invention quickly completes the annular welding at each butt joint to effectively ensure the welding quality of the fin tube 202 group of the entire radiator 2. Start the corresponding front and rear position control units 3 and lifting position control unit 4 of the equipment, so as to achieve the purpose of controlling the corresponding fin tube butt welding forming unit to move into position. When the center of the fin tube butt welding forming unit is coaxial with the center of the four fin tubes 202, the fin tube butt welding forming unit is driven to approach the ends of the four fin tubes 202 by means of the horizontal shifting cooperation of the counter-moving assembly, and at the same time, the corresponding straight tube sections of the two U-shaped bends 203 to be welded and installed are respectively inserted into the corresponding girth welding assemblies. At this time, the fin tube butt welding forming unit is continued to be translated until the corresponding straight tube sections of the U-shaped bends 203 are respectively coaxial with the ends of the corresponding fin tubes 202. The shafts are butt-jointed, and the displacement of the ring welding assembly is continued to be fine-tuned so that each electric welding gun 38 is facing the annular butt seam of the butt joint. The internal components of the ring welding assembly are started to drive the corresponding electric welding gun 38 to perform forward and reverse arc movements along the periphery of the annular butt seam. At the same time, annular welding of the annular butt seam is completed, and finally an annular weld 5 is formed at the end of each fin tube 202, thereby ensuring the welding quality of the U-shaped bend 203 and each fin tube 202 butt joint. During welding, each fin tube butt welding forming unit can simultaneously complete the synchronous forming of four annular welds 5, with high overall welding efficiency and consistent welding standards to ensure welding quality.

[0052] In any of the above schemes, preferably, the main body positioning unit 1 includes a ground seat 6 horizontally fixed on the ground, both sides of the ground seat 6 are bent upward to form side portions, the outer sides of each side portion are respectively connected to the translation assembly at the corresponding position, and two-way clamping mechanisms are respectively installed at intervals on the front and rear sides of the top of the ground seat 6, and the two ends of each of the two-way clamping mechanisms are respectively used to clamp and position the vertical plates 201 on both sides of the fin tube radiator 2.

[0053] When positioning the radiator 2, the main body positioning unit 1 relies on the bidirectional clamping mechanism at the bottom to position the bottom of the two vertical plates 201, thereby ensuring the stability of the positioning of the vertical plates 201. Controlling the horizontal extension and contraction of each bidirectional clamping mechanism can achieve control of the clamping force.

[0054] In any of the above schemes, it is preferred that the bidirectional clamping mechanism includes a supporting seat 7 horizontally fixed on the top of the ground-connecting seat 6, and a gear portion 701 is respectively provided on the left and right sides of the supporting seat 7, and a bidirectional telescopic cylinder 8 is fixedly installed on the top of the supporting seat 7 between the two gear portions 701, and abutment plates 9 are respectively fixedly installed on the ends of the piston rods on the left and right sides of the bidirectional telescopic cylinder 8, and the outer end surfaces of each abutment plate 9 are respectively used to abut the vertical plate 201 against the inner side wall of the corresponding gear portion 701 to complete the clamping and fixing.

[0055] When the bidirectional clamping mechanism is working, controlling the extension and retraction of the corresponding bidirectional telescopic cylinder 8 can drive the piston rods on its left and right sides to synchronously extend and retract in opposite directions or towards each other to drive the abutment plate 9 to move, and then the corresponding vertical plate 201 is clamped and positioned under the clamping action of the corresponding abutment plate 9 and the shifting part 701.

[0056] In any of the above schemes, it is preferred that the front and rear control position unit 3 includes a horizontal frame 10 arranged along the front and rear direction, and a horizontal screw 11 is installed inside the horizontal frame 10. Both ends of the horizontal screw 11 are movably extended to the outside of the horizontal frame 10, and the rear end of the horizontal screw 11 is fixedly connected to the motor shaft of a horizontal drive motor 12 fixedly installed on the rear end surface of the horizontal frame 10. A translation slide 13 is cooperatively installed on the outer side wall of the horizontal screw 11 inside the horizontal frame 10, and the lifting control position unit 4 is fixedly installed on the top of the translation slide 13.

[0057] When the front and rear position control units 3 are working, they rely on the operation of the horizontal drive motor 12 to drive the corresponding horizontal screw 11 to rotate. During the rotation of the horizontal screw 11, it can drive the translation slide 13 to achieve horizontal linear motion, thereby driving the lifting and lowering position control unit 4 fixedly installed on its top to shift along the front and rear direction, and lock it in real time after moving into place.

[0058] In any of the above schemes, it is preferred that the lifting and lowering control unit 4 includes a vertical frame 14 vertically fixedly installed on the top of the translation slide 13, a vertical screw 15 is installed inside the vertical frame 14, guide columns 17 are symmetrically fixedly arranged on the front and rear sides of the vertical screw 15, a lifting seat 16 is cooperatively installed on the outer side wall of the vertical screw 15, and the front and rear sides of the lifting seat 16 are respectively cooperatively sleeved on the outer side walls of the corresponding guide columns 17, the upper and lower ends of the vertical screw 15 are movably inserted into the mounting holes at the corresponding positions of the vertical frame 14, and a lifting motor 18 is fixedly installed in the mounting cavity at the top of the vertical frame 14, the motor shaft of the lifting motor 18 is fixedly connected to the top of the vertical screw 15, and the fin tube butt welding forming unit is fixedly installed on the inner end of the lifting seat 16.

[0059] After the front and rear position control units 3 drive the lifting and lowering position control units 4 thereon to move into position, the lifting and lowering position control units 4 can rely on their own operation to enable the lifting motor 18 to drive the entire vertical screw 15 to rotate. During the rotation of the vertical screw 15, the lifting seat 16 can be prevented from rotating under the action of the guide columns 17 on both sides. Therefore, when the vertical screw 15 rotates, it can only drive the lifting seat 16 to be lifted and lowered in the vertical direction; the forward and reverse rotation of the lifting motor 18 is controlled to control the lifting seat 16 to be lifted and lowered into position, thereby driving the fin tube butt welding forming unit installed on the top of the lifting seat 16 to be lifted and lowered into position.

[0060] In any of the above schemes, it is preferred that the fin tube butt welding forming unit includes two horizontal telescopic cylinders 19 arranged at horizontal intervals, the cylinder barrels of the two horizontal telescopic cylinders 19 are fixed on the lifting seat 16 of the lifting control unit 4, the inner ends of the piston rods of the two horizontal telescopic cylinders 19 are respectively fixedly connected to the connecting frame 20, and an active two-way ring welding mechanism 21 and a driven two-way ring welding mechanism 22 are respectively fixedly installed on the inner upper and lower parts of the connecting frame 20, and the active two-way ring welding mechanism 21 and the driven two-way ring welding mechanism 22 are transmitted through two transmission belts 23.

[0061] It should be noted that: the fin tube butt welding forming unit is initially moved into position under the cooperation of the front and rear position control units 3 and the lifting position control unit 4. At this time, the fin tube butt welding forming unit is located horizontally outward from the corresponding welding position; when it is necessary to control the fin tube butt welding forming unit to be further horizontally close to the welding station, the horizontal telescopic cylinder 19 is controlled to extend to drive the active two-way ring welding mechanism 21 and the driven two-way ring welding mechanism 22 fixed at the end of the connecting frame 20 to move inward. Before the translation, the two U-shaped bends 203 to be welded are pre-installed in the corresponding working space 28 of the corresponding active two-way ring welding mechanism 21 and the driven two-way ring welding mechanism 22 by manual installation operation.

[0062] In any of the above schemes, preferably, in the working state, a U-shaped bend pipe 203 to be welded is respectively installed in the working space 28 of the active two-way ring welding mechanism 21 and the driven two-way ring welding mechanism 22, and under the action of external force, the inner ends of the horizontal sections of each of the U-shaped bend pipes 203 are coaxially butted against the corresponding ends of each fin tube 202 on the radiator 2 to form an annular butt joint;

[0063] The active bidirectional ring welding mechanism 21 and the driven bidirectional ring welding mechanism 22 in the working state respectively drive the miniature electric welding gun 38 installed thereon to perform ring welding on the corresponding ring-shaped butt joints through forward and reverse rotation; after the ring welding process, the U-shaped bend pipe 203 and the two fin tubes 202 form an integrated welding structure.

[0064] When the active two-way ring welding mechanism 21 and the driven two-way ring welding mechanism 22 move into place together with the two U-shaped bends 203, the end faces of the U-shaped bends 203 are coaxially connected with the ends of the corresponding fin tubes 202 to form a pair of annular seams; the active two-way ring welding mechanism 21 is controlled to work, and the corresponding driven two-way ring welding mechanism 22 can be driven to follow the movement under the transmission action of the transmission belt 23, and finally the annular welding positioning of the annular seams of the four butt joints of the four fin tubes 202 and the two U-shaped bends 203 is synchronously completed, and finally the purpose of rapid welding forming positioning is achieved, which effectively improves the welding efficiency and ensures the welding quality.

[0065] In any of the above schemes, it is preferred that the translation assembly includes a translation electric cylinder 24 fixedly arranged at horizontal intervals on the outside of the shifting portion 701, the two translation electric cylinders 24 are in a synchronous telescopic state, the outer ends of the piston rods of the two translation electric cylinders 24 are fixed on the side walls of the horizontal frame 10 of the front and rear control units 3 at their corresponding positions, and the two translation electric cylinders 24 drive the front and rear control units 3 and the components thereon to complete left and right movement through synchronous telescopic movement.

[0066] When the translation assembly is working, it mainly drives the front and rear control units 3 at the outer ends and the lifting control unit 4 on the upper fin tube welding forming unit to follow and achieve translation through the extension and contraction of the corresponding two translation electric cylinders 24, so as to achieve the purpose of approaching or leaving the current radiator 2.

[0067] In any of the above schemes, it is preferred that the movement states of the two fin tube butt welding forming units in the working state do not affect each other.

[0068] The fin tube butt welding forming units on both sides can use independent running tracks when welding and positioning the two ends of each fin tube 202, and the welding processes on both sides do not affect each other, which effectively ensures the relative independence of the welding operations on both sides.

[0069] Embodiment 2: In any of the above schemes, it is preferred that the active bidirectional ring welding mechanism 21 and the driven bidirectional ring welding mechanism 22 use a ring welding component with the same structure, and the power input end of the ring welding component on the active bidirectional ring welding mechanism 21 is powered by a servo driver, and the servo driver includes an angle steel motor seat 25 fixedly mounted on the ring welding component of the active bidirectional ring welding mechanism 21, and a servo motor 26 is mounted on the angle steel motor seat 25, and the output end of the servo motor 26 is connected to the power input end of the ring welding component at its corresponding position.

[0070] When the active two-way ring welding mechanism 21 and the driven two-way ring welding mechanism 22 are working, their structures both adopt ring welding components. The difference is that the active two-way ring welding mechanism 21 is also equipped with a servo motor 26. Therefore, the active two-way ring welding mechanism 21 serves as a driving structure with a power part. When the active two-way ring welding mechanism 21 and the driven two-way ring welding mechanism 22 cooperate, they rely on two annular transmission belts 23 to achieve belt transmission cooperation. Therefore, the operation of a single servo motor 26 can synchronously drive the two ring welding components to complete the operation. Therefore, the four annular butt joints can be synchronously welded and shaped by adjusting the forward and reverse rotation to ensure the welding effect of the butt joint between the end of the fin tube 202 and the U-shaped bend 203.

[0071] In any of the above schemes, it is preferred that the two ring welding components arranged opposite to each other from top to bottom are connected by the two transmission belts 23; in the working state, the two straight pipe sections of the U-shaped bend pipe 203 are both connected in a fitting manner inside the ring welding component.

[0072] In any of the above schemes, it is preferred that the ring welding assembly includes a limit frame 27, the outer side of the limit frame is fixedly connected to the connecting frame 20 on the fin tube butt welding forming unit, and the interior of the limit frame 27 is provided with a working space 28 for the two straight pipe sections of the U-shaped bend 203 to pass through, and both ends of the working space 28 are semicircular surfaces, and arc channels 29 connected to the interior of the working space 28 are provided in the middle of both ends of the limit frame 27, and ring welding components are installed in each of the arc channels 29, and guides are respectively installed on both sides of the middle of the ring welding components, and the ends of each guide are respectively matched with the corresponding limit frames 27 The arc groove 30 is provided with a friction rope drum 31 at the top and bottom of the limit frame 27, and coaxial pulleys 33 are fixed on the outer walls on both sides of the drum shaft 32 of the friction rope drum 31, respectively. The two coaxial pulleys 33 are respectively connected with the coaxial pulleys 33 on the adjacent ring welding components through the transmission belt 23, and the two ends of the drum shaft 32 are respectively movably inserted into the shaft holes of the shaft seats 34 at the corresponding positions, and each of the shaft seats 34 is fixedly connected to the limit frame 27, and friction pull ropes 35 are respectively wound around the two friction rope drums 31, and the two ends of each friction pull rope 35 are fixed on the ring welding components at their corresponding positions.

[0073] It should be noted that the working principle of the ring welding component is as follows: the friction rope drum 31 receives the power of the external servo motor 26 to achieve fixed-axis rotation. When one of the friction rope drums 31 rotates along the fixed axis, it can rely on the friction rope 35 fixedly installed thereon to follow the pulling movement. During the pulling process of the rubber rope, the ring welding component can be driven by the tension to achieve arc displacement along the corresponding arc channel 29 on a certain arc. During the arc displacement of the ring welding component, the guides on both sides play a role in restraining and limiting and reducing the friction resistance of movement. During the arc movement of the ring welding component, the two electric welding guns 38 installed thereon can move around the corresponding annular butt joint. During the movement, controlling the speed of movement can enable the electric welding guns 38 on the ring welding component in the working state to complete the welding of the annular butt joint parts one by one and form a weld. By controlling the sum of the overall movement angles of the two electric welding guns 38 of the ring welding component in the forward and reverse directions to be greater than 360°, the welding process of the entire current annular butt joint can be completed, that is, the angle of each welding gun when it is arc-shifted in sequence is greater than 90°. It should be noted that the arc of each arc-shaped channel 29 is greater than 180°.

[0074] In any of the above schemes, it is preferred that when the friction rope drum 31 rotates, it drives the two ring welding components to perform arc motion inside their respective arc channels 29, and the friction rope drum 31 can realize forward and reverse rotation.

[0075] In any of the above schemes, it is preferred that the annular welding component includes an arc-shaped bin 36 that fits in the arc-shaped channel 29, the guides are fixedly installed on both sides of the middle of the arc-shaped bin 36, the inner arc surface of the arc-shaped bin 36 faces the annular joint between the U-shaped elbow 203 and the fin tube 202 at the corresponding position, and built-in telescopic cylinders 37 are fixedly installed at the upper and lower ends of the arc-shaped inner cavity 3601 of the arc-shaped bin 36, and a miniature electric welding gun 38 is fixedly installed at the inner end of the piston rod of each built-in telescopic cylinder 37. Each electric The working end of the welding gun 38 is movably extended out of the arc-shaped inner cavity 3601 and faces the annular butt joint; a connecting wheel 39 is arranged in the middle of the rear side of the arc-shaped warehouse 36, and the two ends of the wheel axle 40 of the connecting wheel 39 are respectively movably inserted into the rotating holes of the rib plate 41 fixedly connected to the arc-shaped warehouse 36, and the upper and lower parts of the outer side wall of the connecting wheel 39 are respectively fixedly connected to the ends of the friction rope 35 at the corresponding positions. When the friction rope 35 is pulled, it can drive the connecting wheel 39 and the entire arc-shaped warehouse 36 to move along the arc direction of the arc channel 29.

[0076] When the annular welding component moves, it relies on the end of the friction rope 35 to be tensioned, and when the friction rope 35 is subjected to tension, it drives the connecting wheel 39 connected to the corresponding end to drive the entire arc bin 36 to slide in the arc channel 29 with a gap, thereby achieving the purpose of arc movement; considering the smoothness of operation, a guide is provided as a structural member to reduce the movement resistance of the arc bin 36 and constrain the limit. When the arc bin 36 performs a fixed-axis arc movement, the two electric welding guns 38 installed thereon can approach or avoid the current annular butt joint under the small-amplitude telescopic action of the built-in telescopic cylinder 37 inside it, thereby achieving the purpose of quickly adjusting the welding effect. At the same time, after the later welding is completed, the working end of the electric welding gun 38 can be kept separated from the annular weld 5 by retracting the built-in telescopic cylinder 37, ensuring that no motion interference occurs during subsequent outward movement.

[0077] In addition, it should be noted that when welding the U-shaped bend 203, in order to ensure its stability, the bending part of the U-shaped bend 203 can be manually held to ensure the stability of the entire U-shaped bend 203 until the welding is completed.

[0078] In any of the above schemes, it is preferred that the two electric welding guns 38 achieve annular welding of the annular butt joint by shifting forward and backward around the annular butt joint and form an annular weld 5 after welding.

[0079] In any of the above schemes, it is preferred that the guide includes two guide shafts 42 which are arranged at intervals and moveably pass through the middle of the arc-shaped bin 36, and the two ends of the two guide shafts 42 respectively cooperate to pass through the outside of the arc-shaped groove 30 on both sides and are fixedly connected with a limit ring 43 respectively.

[0080] When the arc bin 36 is pulled and moved by the friction rope 35, the guide shaft 42 that can rotate around a fixed axis is inserted into the corresponding arc groove 30 to rotate and move at the same time, which can effectively reduce the resistance of the entire arc bin 36 during displacement and ensure its fluidity and stability during movement.

[0081] In any of the above solutions, preferably, a limiting arc plate 44 is installed on the outer side walls of the two guide shafts 42 between the arc channels 29 on the left and right sides of the arc bin 36.

[0082] In order to further reduce the lateral swing of the arc-shaped bin 36 during the arc-shaped movement, a limiting arc plate 44 is provided to realize the restraint and limit during the lateral swing.

[0083] Specific working principle: first, the bottom of the vertical plates 201 on both sides of the fin tube radiator 2 are clamped and fixed on the main positioning unit 1 respectively; after the positioning is completed, the relative stability of the two vertical plates 201 can be guaranteed. When the vertical plates 201 are installed, each fin tube 202 is installed one by one; the two ends of each fin tube 202 are movable through the through holes on the vertical plates 201 on both sides, and the fin tube 202 is initially installed.

[0084] When the fin tubes 202 are installed each time, four adjacent fin tubes 202 are installed continuously and the central axes of the four fin tubes 202 are connected to form a square.

[0085] Start the corresponding front and rear position control units 3 and lifting position control unit 4 of the equipment, so as to achieve the purpose of controlling the corresponding fin tube butt welding forming unit to move into position. When the center of the fin tube butt welding forming unit is coaxial with the center of the four fin tubes 202, the fin tube butt welding forming unit is driven to approach the ends of the four fin tubes 202 by means of the horizontal displacement of the displacement assembly. At the same time, the corresponding straight tube sections of the two U-shaped bends 203 to be welded and installed are respectively inserted into the corresponding ring welding assemblies. At this time, the fin tube butt welding forming unit is continued to be translated until the corresponding straight tube sections of the U-shaped bends 203 are coaxially docked with the ends of the corresponding fin tubes 202, and the displacement of the ring welding assembly is continued to be fine-tuned to control the rotation so that each electric welding gun 38 is directly facing the annular butt seam of the docking position.

[0086] Start the internal components of the ring welding assembly to drive the corresponding electric welding gun 38 to perform forward and reverse arc movements along the periphery of the ring butt joint, and at the same time complete the ring welding of the ring butt joint, and finally form a ring weld 5 at the end of each fin tube 202, thereby ensuring the welding quality of the U-shaped bend 203 and the butt joint of each fin tube 202.

[0087] During welding, each fin tube butt welding forming unit can simultaneously complete the synchronous forming of four annular welds 5, the overall welding efficiency is high, and the consistent welding standards can ensure the welding quality.

[0088] Specifically, the active bidirectional ring welding mechanism 21 and the driven bidirectional ring welding mechanism 22 cooperate with each other by relying on two annular transmission belts 23 to realize belt transmission cooperation. Therefore, the operation of a single servo motor 26 can synchronously drive the two ring welding components to complete the operation. Therefore, the four annular butt joints can be synchronously welded and shaped by adjusting the forward and reverse rotation to ensure the welding effect of the butt joint between the end of the fin tube 202 and the U-shaped bend tube 203.

[0089] In summary, it can be seen that the present device can quickly complete the welding of the U-shaped bend 203 that matches the end of the installed fin tube 202 during the manufacturing process of the fin tube radiator 2. At the same time, during the welding process, no manual hand-held welding gun operation is required. During welding, only manual assistance is required to install the U-shaped bend 203 in place and complete the circular welding of the current U-shaped bend 203 and the docking parts of the two adjacent fin tubes 202 under remote control, thereby effectively ensuring the welding efficiency. The present device avoids the tedious operation of manual hand-held welding, and can quickly complete the circular weld 5 welding of the ends of two adjacent fin tubes 202 with a narrow spacing, thereby improving the welding efficiency while ensuring the welding quality. When the fin tube radiator 2 rapid welding forming equipment is used for welding, the accuracy of the fin tube welding forming unit moving into position can be ensured by controlling the corresponding front and rear position control units 3, lifting position control units 4 and the linkage displacement of the translation assembly, so that the ends of the fin tubes 202 at different positions on the outside of the vertical plates 201 on both sides of the radiator 2 can be quickly butt-welded with the corresponding U-shaped bends 203 one by one, and the accuracy of the movement into position can be ensured by human observation and the preset position sensors. After each U-shaped bend 203 is welded and positioned, the fin tube welding forming unit can be separated from the current U-shaped bend 203 by quickly translating the fin tube welding forming unit outward, so as to facilitate the displacement to the next welding station. There is no motion interference in the overall welding process before and after, which can ensure the smoothness of displacement and welding; thus, the U-shaped bends 203 can be welded to the ends of all the fin tubes 202 on the entire fin tube radiator 2.

[0090] When installing and positioning the two vertical plates 201 and each fin tube 202 of the radiator 2, the main structure of the radiator 2 can be stably positioned by relying on the clamping positioning and bottom support of the main positioning unit 1, thereby ensuring the reliability and stability of the relative positioning of the entire main structure of the radiator 2 during subsequent welding; the active two-way ring welding mechanism 21 and the driven two-way ring welding mechanism 22 of the fin tube butt welding forming unit are linked by belt drive, so that the butt joints of the two U-shaped bends 203 at the ends of the four fin tubes 202 can be quickly and synchronously welded each time a welding operation is performed, thereby effectively improving the efficiency of butt welding, and the synchronous butt positioning effectively ensures the uniformity of the positioning standards and ensures the welding quality.
