[0002] Condenser tubes are widely used in refrigerators, air conditioners, and other equipment that require condensation. Condenser tubes are typically made by bending Bondi tubing into the desired shape, and then using a condenser tube welding machine to weld steel wire onto the Bondi tubing, thus producing the finished condenser tube. Currently, the welding mechanism used to weld the steel wire onto the formed Bondi tubing is poorly designed, resulting in low welding efficiency. Utility Model Content

[0003] The purpose of this utility model is to overcome the above-mentioned shortcomings in the existing technology and to provide a welding mechanism for a condenser tube welding machine with reasonable structural design and high welding efficiency.

[0004] The technical solution adopted by this utility model to solve the above problems is as follows: The welding mechanism of the condenser tube welding machine includes two welding structures, characterized in that it further includes a servo motor, a reducer, a base plate, two base plate push-pull structures, an insulating plate, a transition copper plate, and a copper beam. The base plate, insulating plate, transition copper plate, and copper beam are fixed sequentially from bottom to top. Each welding structure includes several copper electrode rods, two copper columns, and an electrode rod fixing copper plate. The two copper columns are vertically fixed on the copper beam, and the electrode rod fixing copper plate is fixed on the top of the two copper columns. Several copper electrode rods are fixed on the electrode rod fixing copper plate. The servo motor, reducer, and two base plate push-pull structures are all fixed on the condenser tube welding machine frame. The servo motor is connected to the reducer, the reducer is connected to the two base plate push-pull structures, and the two base plate push-pull structures are connected to the base plate.

[0005] Preferably, the welding mechanism of this utility model further includes two limit beam push-pull structures, two Bondi tube lateral limit members, and one limit beam. Each limit beam push-pull structure includes a fixed plate, a limit beam push-pull cylinder, a limit beam slide rail, a limit beam slide groove, and a limit beam connecting plate. The fixed plate is fixed to the copper beam. The limit beam push-pull cylinder and the limit beam slide rail are both mounted on the fixed plate. The limit beam slide groove is mounted on the limit beam slide rail. The limit beam connecting plate is fixed on the limit beam slide groove. The piston end of the limit beam push-pull cylinder is connected to the limit beam connecting plate. Both ends of the limit beam are fixed to the two limit beam connecting plates respectively. The two Bondi tube lateral limit members are both fixed to the limit beam, and the two Bondi tube lateral limit members correspond to the two welding structures respectively.

[0006] Preferably, each base plate push-pull structure of this utility model includes a base plate push-pull base, a bearing seat, a rotating shaft, an eccentric wheel, a transmission pin, a connecting rod, a push-pull seat, a base plate base, a base plate slide rail, and a base plate slide groove. The base plate push-pull base and the base plate base are both fixed on the frame of the condenser pipe welding machine. The rotating shaft is mounted on the base plate push-pull base through the bearing seat. One end of the rotating shaft is connected to a reducer, and the other end of the rotating shaft is fixed with an eccentric wheel. The transmission pin is fixed on the eccentric wheel. The push-pull seat and the base plate are fixed. One end of the connecting rod is rotatably connected to the transmission pin, and the other end of the connecting rod is rotatably connected to the push-pull seat. The base plate slide rail is fixed on the base plate base, the base plate slide groove is installed on the base plate slide rail, and the bottom of the base plate is fixed on the two base plate slide grooves.

[0007] Preferably, each copper column of this invention is equipped with a copper column adjusting component. The copper beam has sliding grooves on both sides, and the lower part of the adjusting component is slidably connected to the grooves of the copper beam. The upper part of the adjusting component is connected to the copper column by screws. When it is necessary to move the position of the copper column on the copper beam, simply loosen the screws to allow the copper column to move on the copper beam; once the copper column has moved to the desired position, simply tighten the screws to position the copper column on the copper beam.

[0008] Preferably, the number of copper electrode rods in each welding structure of this invention is 6 to 16.

[0009] Preferably, the limiting member beam connecting plate of this utility model has an L-shaped structure.

[0010] Compared with the prior art, this utility model has the following advantages and effects: The base plate is controlled to move forward and backward via a push-pull structure. When a steel wire needs to be welded onto a bent Bundy tube, the push-pull structure pushes the base plate forward, causing the welding structure to move forward synchronously. A steel wire is welded onto the bent Bundy tube via a copper electrode rod on the welding structure. After one wire is welded, the push-pull structure pulls the base plate backward, causing the welding structure to move backward synchronously. The bent Bundy tube is then lifted upward a short distance. The push-pull structure then pushes the base plate forward again, causing the welding structure to move forward synchronously again. A second steel wire is welded onto the corresponding position on the bent Bundy tube via a copper electrode rod on the welding structure. This push-pull structure repeats the process, gradually lifting the Bundy tube to be welded, ensuring that all corresponding positions on the entire Bundy tube are welded with steel wire, resulting in high welding efficiency.

Detailed Implementation

[0021] The present invention will be further described in detail below with reference to the accompanying drawings and through embodiments. The following embodiments are explanations of the present invention, but the present invention is not limited to the following embodiments.

[0022] Example

[0023] See Figures 1 to 8 The welding mechanism of the condenser tube welding machine in this embodiment includes a servo motor 1, a reducer 2, a base plate 3, two base plate push-pull structures 4, two welding structures 5, two limit member crossbeam push-pull structures 6, an insulating plate 7, a transition copper plate 8, a copper beam 9, two Bundy tube transverse limit members 10 and a limit member crossbeam 11.

[0024] In this embodiment, the base plate 3, insulating plate 7, transition copper plate 8, and copper beam 9 are fixed sequentially from bottom to top. The transition copper plate 8 can be connected to the transformer through a copper braided strip for energizing. The base plate 3 and the transition copper plate 8 are insulated from each other by the insulating plate 7. After the transition copper plate 8 is energized, it will conduct electricity to the copper beam 9.

[0025] Each welding structure 5 in this embodiment includes several copper electrode rods 51, two copper columns 52, and a copper electrode fixing plate 53. The number of copper electrode rods 51 in each welding structure 5 is typically 6 to 16. The two copper columns 52 are vertically fixed to the copper beam 9, the copper electrode fixing plate 53 is fixed to the top of the two copper columns 52, and the several copper electrode rods 51 are fixed to the copper electrode fixing plate 53. When the transition copper plate 8 is energized, the electricity on the copper beam 9 is sequentially conducted to the copper columns 52 and the copper electrode fixing plate 53, and then conducted to the copper electrode rods 51 through the copper electrode fixing plate 53, thereby enabling the copper electrode rods 51 to weld the steel wire 100 to the Bundy tube 200. The need to weld the steel wire 100 to the Bundy tube 200 is common knowledge to those skilled in the art.

[0026] In this embodiment, each copper column 52 can be equipped with a copper column adjusting component 54. Slide grooves can be formed on both sides of the copper beam 9. The lower part of the copper column adjusting component 54 is slidably connected to the slide groove of the copper beam 9, and the upper part of the copper column adjusting component 54 is connected to the copper column 52 by screws. When it is necessary to move the position of the copper column 52 on the copper beam 9, simply loosen the screws, and the copper column 52 can move on the copper beam 9. After the copper column 52 has moved to the desired position, simply tighten the screws to position the copper column 52 on the copper beam 9. Of course, in this invention, the copper column 52 may not have a copper column adjusting component 54, and the copper column 52 can be directly fixed to the copper beam 9 by screws or bolts.

[0027] In this embodiment, the servo motor 1, the reducer 2, and the two base plate push-pull structures 4 are all fixed on the frame of the condenser pipe welding machine. The servo motor 1 and the reducer 2 are connected, and the servo motor 1 can drive the reducer 2 to rotate. The reducer 2 is connected to the two base plate push-pull structures 4, and the two base plate push-pull structures 4 are connected to the base plate 3.

[0028] Each base plate push-pull structure 4 in this embodiment includes a base plate push-pull base 41, a bearing seat 42, a rotating shaft 43, an eccentric wheel 44, a transmission pin 45, a connecting rod 46, a push-pull seat 47, a base plate base 48, a base plate slide rail 49, and a base plate slide groove 50. The base plate push-pull base 41 and the base plate base 48 are both fixed to the frame of the condenser pipe welding machine. The rotating shaft 43 is mounted on the base plate push-pull base 41 via the bearing seat 42, and can rotate on the bearing seat 42. One end of the rotating shaft 43 is connected to the reducer 2, which drives the rotating shaft 43 to rotate. The other end of the rotating shaft 43 is fixed to the eccentric wheel 44, which can rotate with the eccentric wheel 44. The transmission pin 45 is fixed to the eccentric wheel 44 and can rotate with the eccentric wheel 44. The push-pull seat 47 and the base plate 3 are fixed. One end of the connecting rod 46 is rotatably connected to the transmission pin 45, and the other end of the connecting rod 46 is rotatably connected to the push-pull seat 47. When the transmission pin 45 rotates with the eccentric wheel 44, the transmission pin 45 will reciprocate to push and pull the connecting rod 46. At the same time, the connecting rod 46 will transmit the reciprocating pushing and pulling force to the push-pull seat 47, so that the push-pull seat 47 can reciprocate to push and pull the base plate 3. The base plate slide rail 49 is fixed on the base plate base 48, and the base plate slide groove 50 is installed on the base plate slide rail 49. The bottom of the base plate 3 is fixed on the two base plate slide grooves 50. When the base plate 3 is subjected to the pushing or pulling force of the push-pull seat 47, the base plate 3 can move forward or backward along the slide rail 49. If the force exerted by the push-pull seat 47 on the base plate 3 is reciprocating, the base plate 3 will reciprocate back and forth along the slide rail 49.

[0029] Each limiting member beam push-pull structure 6 in this embodiment includes a fixed plate 61, a limiting member beam push-pull cylinder 62, a limiting member beam slide rail 63, a limiting member beam slide groove 64, and a limiting member beam connecting plate 65, wherein the limiting member beam connecting plate 65 has an L-shaped structure. The fixed plate 61 is fixed to the copper beam 9. The limiting member beam push-pull cylinder 62 and the limiting member beam slide rail 63 are both installed on the fixed plate 61. The limiting member beam slide groove 64 is installed on the limiting member beam slide rail 63 and can slide along the limiting member beam slide rail 63. The limiting member beam connecting plate 65 is fixed on the limiting member beam slide groove 64. The piston end of the limiting member beam push-pull cylinder 62 is connected to the limiting member beam connecting plate 65. The limiting member beam push-pull cylinder 62 can drive the limiting member beam connecting plate 65 to move along the limiting member beam slide rail 63 through the piston. Both ends of the limiting beam 11 are fixed to the two limiting beam connecting plates 65. Two Bondi tube lateral limiting components 10 are fixed to the limiting beam 11. The Bondi tube lateral limiting components 10 restrict the lateral movement of the Bondi tube 200. When steel wires 100 need to be welded onto the Bondi tube 200, the Bondi tube 200 will rise step by step, thereby welding the steel wires 100 one by one onto the Bondi tube 200. The two Bondi tube lateral limiting components 10 correspond to two welding structures 5, that is, each welding structure 5 corresponds to one Bondi tube lateral limiting component 10.

[0030] Furthermore, it should be noted that the specific embodiments described in this specification may differ in the shape and name of their components. The above description is merely illustrative of the structure of this utility model. All equivalent or simple variations made based on the structure, features, and principles described in this utility model patent concept are included within the protection scope of this utility model patent.
