Description

Technical Field

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

[0002] Finned tubes are needed in the production of radiators. In order to improve the heat exchange efficiency, fins are usually added to the surface of the heat dissipation tubes to increase the outer surface area (or inner surface area) of the heat exchange tubes, thereby achieving the purpose of improving the heat exchange efficiency. Finned tubes are one of the commonly used heat dissipation materials for radiators. When the finned tubes are assembled and processed, the ends of multiple finned tubes will first be limited by a frame plate, and then the two adjacent finned tubes will be connected. The connection method mainly adopts a U-shaped tube to weld the ends of the two adjacent finned tubes. The U-shaped tube has two ends whose axes are parallel to each other. Due to the shape limitation of the U-shaped tube, most of the existing welding equipment is inconvenient to operate. When welding, the U-shaped tube and the finned tube are mainly welded by manual handheld welding equipment. However, during positioning, it is limited by the special shape of the U-shaped tube and requires multiple people to operate simultaneously, which leads to inconsistent welding rates during welding operations, and there are cases of cold welding and transition welding. At the same time, the experience requirements of the staff are relatively high, which will affect the heat dissipation effect of the radiator. Chinese patent CN116511715B discloses a The fin assembly equipment for radiator processing includes an assembly table arranged at both sides of the conveyor belt, a processing seat is rotatably arranged on the assembly table, a plurality of conveying ports are opened on the processing seat, an electric push rod is arranged on the inner wall of the conveying port, a magnetic feed component is connected to the output end of the electric push rod, and a collecting table is connected to one side of the assembly table through a support frame. This invention connects the U-shaped tube with the fin tube by a magnetic clamping and pushing ring arranged in the conveying port, and carries the laser welder by designing a track ring and using a movable rail to realize the circular rotation of the laser welder through the structure on the movable rail. However, there are various types of U-shaped tubes on the radiator, and the straight-line distances between the two ends of different U-shaped tubes will be different. At the same time, the diameter of the U-shaped tube will also change. When the equipment is connected with the fin tube, the positions of the two fin tubes and the two laser welders need to be adjusted, which makes the adjustment of the equipment more complicated during the change of the model. At the same time, when the diameter of the U-shaped tube changes, the axis of the track ring and the end of the U-shaped tube also need to be set to be coaxial to achieve uniform circular welding, which further increases the difficulty of equipment adjustment during the change of the model.

DETAILED DESCRIPTION

[0030] In order to further understand the features, technical means, specific objectives and functions of the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0031] like Figures 1 to 5 , Figure 8 , Fig. 9 and Fig.11 As shown: A fin welding assembly equipment for radiator production, including a frame 1, on which is provided a bearing platform 2 which can slide along its height direction and is used to place a U-shaped tube 4, on which is provided two first support seats 21 which can slide relatively along the length direction of the bearing platform 2; on the frame 1, there are provided two positioning seats 3 which are respectively sleeved on the two first support seats 21, on which is provided an annular track 32 which is coaxial with the axis of the end of the U-shaped tube 4 and two first clamping claws 31 which can rotate relatively, on which is provided an annular track 32 which is coaxial with the axis of the end of the U-shaped tube 4 and two first clamping claws 31 which can rotate relatively, and on which is provided a welding assembly 321 which rotates around its axis, and the two first clamping claws 31 are both transmission connected to the first support seat 21.

[0032] First, the bending part of the U-shaped tube 4 is placed on the supporting platform 2, and the two ends of the U-shaped tube 4 are placed on the two first support seats 21 respectively. Before placement, the linear distance between the two ends of the U-shaped tube 4 is matched by relative sliding of the two first support seats 21, so that the equipment can be adjusted for different types of U-shaped tubes 4, thereby improving the adaptability of the equipment. When the diameter of the U-shaped tube 4 changes, if the first support seat 21 cannot be raised or lowered, the axis of the U-shaped tube 4 will change when the two first clamping claws 31 clamp it. Since the annular track 32 is set The first support seat 21 is mounted on the positioning seat 3, and the positioning seat 3 is sleeved on the first support seat 21, so that the annular track 32 can only slide along the length direction of the carrier 2, but cannot be lifted or lowered with the carrier 2, so that when the welding assembly 321 on the annular track 32 is welding the ends of the U-shaped tube 4 and the fin tube 5, the distance between the welding assembly 321 and the axis of the U-shaped tube 4 will be inconsistent, so that the welding assembly 321 needs to be able to slide along the radial direction of the annular track 32, but this method may cause inconsistent welds after welding and poor welding effect during welding. The two clamping claws are ensured to be coaxial with the annular track 32 when clamping the end of the U-shaped tube 4. The bearing platform 2 can slide along the height direction of the frame 1 to drive the two first clamping claws 31. The movement of the bearing platform 2 drives the two first support seats 21 to move along the height direction of the frame 1, thereby driving the U-shaped tube 4 located on the first support seat 21, so that the U-shaped tube 4 can be lifted. At the same time, the two clamping claws rotate relative to each other to clamp the two sides of the end of the U-shaped tube 4, so that the axis of the end of the U-shaped tube 4 after being clamped is aligned with the annular track. The axis of 32 is coaxially arranged, so that when the subsequent welding assembly 321 rotates along the annular track 32, there is no need to adjust the position of the welding assembly 321, so that the welding assembly 321 can evenly surround the end of the U-shaped tube 4 to weld the fin tube 5 thereto, and when the end of the U-shaped tube 4 is welded in the above manner, the first support seat 21 and the two clamping claws make the axis of the end of the U-shaped tube 4 always consistent with the axis of the annular track 32, thereby facilitating the improvement of the welding effect and welding efficiency after the U-shaped tube 4 and the fin tube 5 are butt-jointed.

[0033] like Figures 1 to 5 , Figure 8 , Fig. 9 and Fig.11 As shown: the first clamping claw 31 is a semicircular arc structure, and an inclined first slide groove 311 is provided at the bottom of the first clamping claw 31, a driving rod 211 slidingly matched with the first slide groove 311 is provided on the first support seat 21, and a pulley 2111 is provided on the driving rod 211, and two first support rods 33 are provided on the positioning seat 3, and the two first clamping claws 31 are respectively mounted on the two first support rods 33 in a mirror-symmetrical state.

[0034] The movement of the first support seat 21 can drive the movement of the two driving rods 211, so that the driving rod 211 can slide along the first sliding groove 311, and the driving rod 211 can drive the first clamping claw 31 to rotate around the first support rod 33 with the first support seat 21 as the center, so that when the first support seat 21 rises, it can drive the two first clamping claws 31 to move closer to the U-shaped tube 4 relatively, and position the end of the U-shaped tube 4 through three points to improve its stability and facilitate the stability of subsequent welding. At the same time, in this way, the first support seat 21 and the two clamping claws make the axis of the end of the U-shaped tube 4 always consistent with the axis of the annular track 32, so as to facilitate the improvement of the welding effect and welding efficiency after the U-shaped tube 4 and the fin tube 5 are connected. The setting of the pulley 2111 can play a certain limiting role, further improving the stability of the transmission between the two.

[0035] like Figures 1 to 5 , Figure 8 , Fig. 9 and Fig.11 As shown: the positioning seat 3 is provided with a slide rail 34 extending along the width direction of the supporting platform 2, the slide rail 34 is provided with a support frame 341 that slides with it, and the support frame 341 is provided with two second support seats 3411 that respectively support the two ends of the fin tube 5, and the second support seat 3411 can be raised and lowered synchronously with the first support seat 21.

[0036] When the finned tube 5 is welded with the U-shaped tube 4, the two finned tubes 5 are respectively placed on the support frames 341 of the two positioning seats 3, and the two second support seats 3411 on the support frames 341 support the two ends of the finned tube 5, so that the finned tube 5 can remain in a horizontal state. Through the setting of the slide rail 34, the support frame 341 can slide on the slide rail 34, and the second support seat 3411 drives the finned tube 5 to move toward the end of the U-shaped tube 4, so as to facilitate the docking of the end of the finned tube 5 with the end of the U-shaped tube 4. Through the setting of the slide rail 34, the support frame 341 can move synchronously with the positioning seat 3. When the positioning seat 3 adjusts its position with the first support seat 21, the position of the support frame 341 can also be adjusted. Through the setting of the second support seat 3411 can be raised and lowered synchronously with the first support seat 21, the axis of the finned tube 5 can be kept coaxial with the axis of the U-shaped tube 4 when docking with the U-shaped tube 4, thereby improving the accuracy of the connection between the two.

[0037] like Figure 1 , Figures 4 to 10 As shown: two second support seats 3411 of the support frame 341 are each provided with two second clamping claws 3412 that can rotate relative to each other. The structure of the second clamping claws 3412 is completely consistent with the structure of the first clamping claws 31. The second clamping claws 3412 can clamp the fin tube 5 synchronously with the start-up of the first clamping claws 31.

[0038] By setting the second clamping claw 3412, the support frame 341 can clamp the two ends of the fin tube 5 while supporting the two ends of the fin tube 5, so as to more stably drive the fin tube 5 to move toward the U-shaped tube 4 along its axial direction, so that the end of the U-shaped tube 4 can dock with the end of the fin tube 5. The second clamping claw 3412 can clamp the fin tube 5 synchronously with the start of the first clamping claw 31, so that the fin tube 5 is also positioned when the U-shaped tube 4 is positioned, which is convenient for the subsequent support frame 341 to drive the fin tube 5 to move, so that the fin tube 5 and the end of the U-shaped tube 4 can dock.

[0039] like Figures 5 to 10 As shown: the support frame 341 includes two mounting frames 3413 that can slide along the slide rail 34, and the two second support seats 3411 are slidably set on the two mounting frames 3413 respectively. The opposite sides of the two mounting frames 3413 are respectively provided with coaxial sleeves 34131 and rotatable threaded rods 34132, and the threaded rods 34132 are sleeved in the sleeves 34131 and threadedly matched therewith.

[0040] When the fin tube 5 is placed on the second support seat 3411, since the length of the fin tube 5 will vary due to different models, by rotating the threaded rod 34132, the sleeve 34131 and the threaded rod 34132 are threadedly matched, so that the sleeve 34131 can slide along the axis of the threaded rod 34132, thereby extending the distance between the two mounting frames 3413, so that the distance between the second support seats 3411 on the two mounting frames 3413 can match the fin tubes 5 of different lengths, thereby supporting the two ends of the fin tube 5, making it more convenient for the fin tube 5 to be docked with the U-shaped tube 4, improving the stability during welding, and further improving the adaptability of the equipment.

[0041] like Figures 5 to 10 As shown: two second slide grooves 212 extending along the width direction of the supporting platform 2 are arranged at the bottom of the frame 1, a driving frame 2121 slidingly matched with the two second slide grooves 212 is arranged between the two second slide grooves 212, and a third slide groove 21211 perpendicular to the second slide groove 212 is arranged on the driving frame 2121, and driving blocks 34133 fixedly connected to the sleeves 34131 of the two supporting frames 341 are arranged, and the two driving blocks 34133 can be slidably arranged on the third slide groove 21211.

[0042] After the two fin tubes 5 are placed, the two fin tubes 5 can be synchronously moved toward the U-shaped tube 4 to better dock with the U-shaped tube 4, and at the same time, it is convenient to carry out synchronous welding, which improves the subsequent welding efficiency. Through the arrangement of the driving frame 2121 and the second slide groove 212, the driving frame 2121 can slide along the second slide groove 212. Through the arrangement of the third slide groove 21211 and the two driving blocks 34133, when the driving block 34133 is driven by the driving frame 2121 to slide along the second slide groove 212, the two driving blocks 34133 can also slide on the third slide groove 21211 to match the distance between the two ends of the U-shaped tube 4 of different models. The driving frame 2121 can synchronously drive the two fin tubes 5 to move toward the U-shaped tube 4. A first screw rod 2122 parallel to the two second slide grooves 212 can be arranged between the two second slide grooves 212. The first screw rod 2122 can be rotatably arranged on the frame 1. 1 is set on the first screw rod 2122 and cooperates with its thread. The frame 1 is also provided with a first rotation driving motor 2123 for driving the first screw rod 2122 to rotate. By starting the first rotation driving motor 2123, the first screw rod 2122 connected to it is driven to rotate. The rotation of the first screw rod 2122 drives the driving frame 2121 threadedly matched with it to slide along the second slide groove 212, thereby realizing that the two driving blocks 34133 can also slide along the second slide groove 212, and the driving block 34133 drives the movement of the sleeve 34131 fixedly connected to it, and the movement of the sleeve 34131 drives the movement of the mounting frame 3413, and the movement of the mounting frame 3413 drives the movement of the supporting frame 341, so that the fin tube 5 can be conveniently connected to the U-shaped tube 4. This method can reduce the problem of installing driving sources for the two separately, thereby reducing the cost of the equipment.

[0043] like Figures 5 to 10 As shown: the driving rod 211 on the first supporting seat 21 is a hollow structure, a retractable sliding rod 34121 is arranged between the first sliding grooves 311 of the two second clamping claws 3412, the sliding rod 34121 can be slidably mounted on the driving rod, and two second supporting rods 34134 which are coaxial with the two first supporting rods 33 on the positioning seat 3 are arranged on the mounting frame 3413, and the two second clamping claws 3412 are respectively mounted on the two second supporting rods 34134.

[0044] By setting the retractable sliding rod 34121, when the distance between the two mounting frames 3413 changes, the sliding rod 34121 can match it, and the transmission between the two will not be affected after the extension and retraction. By setting the driving rod 211 as a hollow structure, and the end of the sliding rod 34121 is sleeved on the driving rod 211, when the fin tube 5 is driven to move toward the U-shaped tube 4, the sliding rod 34121 can match the change in the distance between the end of the fin tube 5 and the U-shaped tube 4 by sliding, so that the first support seat 21 can drive the sliding rod 34121 to move when the driving rod 211 is moved. The movement of 121 drives the two second clamping claws 3412 to rotate with the second support rod 34134 as the center, so that the second clamping claws 3412 can move synchronously with the first clamping claw 31, thereby clamping the end of the U-shaped tube 4 and the end of the fin tube 5 respectively. The clamping of the end of the U-shaped tube 4 is used to position the U-shaped tube 4 and improve the stability of welding. The clamping of the end of the fin tube 5 facilitates to improve the stability of the fin tube 5 when sliding toward the U-shaped tube 4. At the same time, it can reduce the installation of the driving source, so that the movement of the first support seat 21 can drive the first clamping claw 31 and the second clamping claw 3412 to reduce the cost of the equipment.

[0045] like Figures 5 to 7 As shown: a fourth slide groove 34135 extending along the height direction of the frame 1 is provided on the mounting frame 3413, the second support seat 3411 is slidably arranged on the fourth slide groove 34135, and the bottom of the second support seat 3411 is sleeved on two sliding rods 34121.

[0046] By setting the fourth slide groove 34135, the second support seat 3411 can slide stably on the mounting frame 3413. In order to ensure that the second support seat 3411 can be raised and lowered synchronously with the first support seat 21, the bottom of the second support seat 3411 is sleeved on the two sliding rods 34121. When the first support seat 21 moves, it will drive the movement of the driving rod 211. The movement of the driving rod 211 drives the movement of the sliding rod 34121. The movement of the sliding rod 34121 drives the movement of the second support seat 3411, so that the second support seat 3411 can slide along the fourth slide groove 34135. In this way, the problem of needing to install an independent driving source for the second support seat 3411 can be reduced, thereby reducing the cost of the equipment. This method has a higher degree of synchronization and avoids debugging between multiple driving sources.

[0047] like Figures 6 to 9 and Fig.11 As shown, the tops of the first clamping claw 31 and the second clamping claw 3412 are both provided with abutment wheels 312, and the tops of the first support seat 21 and the second support seat 3411 are both semicircular arc structures.

[0048] By setting the abutment wheel 312, the first clamping claw 31 and the second clamping claw 3412 are not likely to scratch the surface of the U-shaped tube 4 and the fin tube 5 when positioning them respectively. By setting the tops of the first support seat 21 and the second support seat 3411 to be semi-circular arc structures, the ends of the U-shaped tube 4 and the ends of the fin tube 5 can be placed on the first support seat 21 and the second support seat 3411 more stably, avoiding the problem of shaking of the U-shaped tube 4 and the fin tube 5 on the first support seat 21 and the second support seat 3411.

[0049] like Figures 1 to 5 and Fig.10 As shown: a linear drive 11 is arranged at the bottom of the frame 1, two guide rods 12 are arranged on the frame 1, the bearing platform 2 is sleeved on the two guide rods 12 and slidably cooperates with them, and the bearing platform 2 is transmission-connected with the linear drive 11.

[0050] The linear drive 11 is preferably a cylinder, which drives the movement of the supporting platform 2 connected thereto through the output shaft of the cylinder, so that the supporting platform 2 slides along the axial direction of the two guide rods 12, thereby enabling the supporting platform 2 to slide along the height direction of the frame 1. At the same time, the movement of the supporting platform 2 can also drive the two first support seats 21 connected thereto, so that the two first support seats 21 can also slide along the height direction of the frame 1.

[0051] The supporting platform 2 is also provided with a second screw rod 23 and a fifth slide groove 31124 extending along its length direction, and a second rotation driving motor 22 that can drive the second screw rod 23 to rotate is provided on the side wall of the supporting platform 2. The two first support seats 21 are respectively sleeved on the second screw rod 23 and matched with its thread. The two ends of the second screw rod 23 have mutually opposite threads, and the two first support seats 21 can be slidably set on the fifth slide groove 31124. By starting the second rotation driving motor 22, the second screw rod 23 connected to it is driven to rotate, and the rotation of the second screw rod 23 drives the movement of the two first support seats 21 matched with its thread. Since the two ends of the second screw rod 23 have mutually opposite threads, the two first support seats 21 slide relatively along the fifth slide groove 31124, thereby realizing the adjustment of the distance between the two first support seats 21, so that when replacing the U-shaped tube 4, the type can be changed quickly, reducing the debugging time.

[0052] The above embodiments only express one or several implementation modes of the present invention, and the description thereof is relatively specific and detailed, but it cannot be understood as limiting the scope of the present invention. It should be pointed out that, for those of ordinary skill in the art, several variations and improvements can be made without departing from the concept of the present invention, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the present invention shall be subject to the attached claims.
