Description

Technical Field

[0001] This utility model relates to the field of steel pipe welding technology, specifically to a steel pipe welding device for refrigerator cores. Background Technology

[0002] The core components of a refrigerator typically include the evaporator, absorber, and condenser. Among these, the condenser, as a crucial heat exchange unit in the refrigerator's refrigeration system, is responsible for cooling and heat dissipation; its manufacturing quality directly affects the overall performance and lifespan of the refrigerator. During condenser manufacturing, multiple steel pipes are usually installed and welded to one side of the condenser to form a condensation circulation loop.

[0003] As shown in the reference case "An Adjustable Welding Station for Welding Steel Pipes" (Announcement No. CN221560357U), the angle of the worktable can be tilted, thereby enabling the first clamping plate and the second clamping plate to tilt, which in turn enables the steel pipe to tilt, facilitating welding at tricky angles for steel pipe connections and improving the welding effect.

[0004] While existing fixtures or welding tables for welding condenser steel pipes have multi-angle adjustment capabilities, when welding multiple steel pipes sequentially, it is usually necessary to evenly arrange the pipes along the horizontal direction of the condenser body and ensure precise alignment of each welding point. After completing the welding of a single pipe, existing fixtures are prone to horizontal position deviations during movement or adjustment, affecting the positioning accuracy and consistency of the welding.

[0005] Based on this, the present invention designs a steel pipe welding device for refrigerator core to solve the above problems. Utility Model Content

[0006] In view of the above-mentioned shortcomings of the existing technology, the present invention provides a steel pipe welding device for refrigerator core.

[0007] To achieve the above objectives, this utility model provides the following technical solution:

[0008] A steel pipe welding device for refrigerator core includes a welding machine, on one side of which a welding torch is fixedly mounted; a control translation mechanism for controlling the horizontal movement of a clamp to weld two steel pipes to a refrigerator condenser is located on one side of the welding machine; wherein the control translation mechanism includes two clamps located on one side of the welding torch, an adjustment and movement assembly is provided on one side of the two clamps, and a placement assembly is provided on one side of the welding machine.

[0009] Furthermore, the adjusting moving component includes a movable frame disposed on one side of the welding machine, an electric telescopic plate fixedly mounted on the surface of the movable frame, two clamping plates disposed on one side of the electric telescopic plate, a fixed plate fixedly mounted on one side of the welding machine, the movable frame slidably mounted on the surface of the fixed plate, a drive rod rotatably mounted on one side of the fixed plate, a plurality of teeth fixedly mounted on the surface of the drive rod, a toothed plate fixedly mounted inside the movable frame, the toothed plate slidably connected to the fixed plate, and the toothed plate is located on one side of the plurality of teeth, the toothed plate meshing with adjacent teeth.

[0010] Furthermore, one side of the electric telescopic plate is provided with an electric slide rail, which has two output ends, and the two output ends are respectively fixedly connected to two clamping plates.

[0011] Furthermore, a rotary motor is fixedly installed on one side of the electric telescopic plate, and the output end of the rotary motor is fixedly connected to one side of the electric slide rail.

[0012] Furthermore, the placement assembly includes a tray rotatably mounted on top of the welding machine, on the surface of which two placement plates are slidably connected, and both placement plates have grooves on their surfaces.

[0013] Furthermore, an electric push rod is fixedly installed on the top of the welding machine, and a connecting block is rotatably installed on the output end of the electric push rod, the connecting block being slidably connected to the support plate.

[0014] Furthermore, a bidirectional screw is rotatably mounted on the surface of the tray, the bidirectional screw passing through one side of the two placement plates and threadedly connected to the two placement plates.

[0015] Furthermore, rubber plates are fixedly installed inside both of the placement plates, and multiple friction grooves are formed on the adjacent side of each of the two rubber plates. Beneficial effects

[0016] 1. During welding operations, adjusting the moving assembly not only allows for angle adjustment of the steel pipe, but also enables the two clamping plates to move horizontally after the first welding position is determined. When welding multiple horizontally arranged steel pipes, only the position of the first steel pipe needs to be confirmed initially. Subsequent welding processes only require opening and closing the clamping plates sequentially to clamp and position the next steel pipe, avoiding frequent clamping adjustments and improving welding efficiency and positioning accuracy. At the same time, the placement assembly supports the refrigerator condenser body and can be angled as needed, facilitating the positioning and stability of the condenser during welding and enhancing the overall convenience and reliability of the welding operation.

[0017] 2. The distance between the two placement plates can be adjusted by sliding according to the size of the condenser body to accommodate condensers of different specifications. The extension and retraction of the electric push rod can drive the connecting block to move up and down, thereby adjusting the angle or height of the support plate. Attached Figure Description

[0026] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0027] The present invention will be further described below with reference to the embodiments.

[0028] In some embodiments, please refer to the appendix to the instruction manual. Figure 1-5 A steel pipe welding device for refrigerator core includes a welding machine 1, a welding torch 2 fixedly mounted on one side of the welding machine 1; and a control translation mechanism 3, which is used to control the horizontal movement of the clamps to weld two steel pipes to the refrigerator condenser. The control translation mechanism 3 is located on one side of the welding machine 1. The control translation mechanism 3 includes two clamping plates 31 located on one side of the welding torch 2, an adjustment and movement component 32 located on one side of the two clamping plates 31, and a placement component 33 located on one side of the welding machine 1.

[0029] In this embodiment of the utility model, during welding operations, by adjusting the moving component 32, not only can the angle of the steel pipe be adjusted, but also after determining the first welding position, the two clamping plates 31 can be directly driven to move horizontally. When welding multiple horizontally arranged steel pipes, it is only necessary to confirm the position of the first steel pipe initially. In subsequent welding processes, it is only necessary to open and close the clamping plates 31 in sequence to complete the clamping and positioning of the next steel pipe, avoiding frequent clamp adjustment operations and improving welding efficiency and positioning accuracy. At the same time, the placement component 33 is used to support the refrigerator condenser body and can be adjusted in angle as needed, which facilitates the positioning and stability of the condenser during the welding process and improves the convenience and reliability of the overall welding operation.

[0030] Existing welding equipment typically includes a welding machine 1, a welding torch 2, a power supply system, a control system, and a cooling system. The structure of the adjusting and moving components 32 and the placement components 33 are rationally integrated with the main structure of the welding machine 1. The two operate through independent sliding and rotating control systems, without affecting the original welding work and function realization of the welding machine 1.

[0031] In some embodiments, such as Figure 2 , Figure 3 and Figure 4As shown, the adjusting moving component 32 includes a movable frame 321 disposed on one side of the welding machine 1. An electric telescopic plate 322 is fixedly installed on the surface of the movable frame 321. Two clamping plates 31 are disposed on one side of the electric telescopic plate 322. A fixed plate 325 is fixedly installed on one side of the welding machine 1. The movable frame 321 is slidably installed on the surface of the fixed plate 325. A drive rod 326 is rotatably installed on one side of the fixed plate 325. Multiple teeth 327 are fixedly installed on the surface of the drive rod 326. A toothed plate 328 is fixedly installed inside the movable frame 321. The toothed plate 328 is slidably connected to the fixed plate 325, and the toothed plate 328 is located on one side of the multiple teeth 327. The toothed plate 328 is meshed with adjacent teeth 327.

[0032] In this embodiment of the utility model, the steel pipe is fixed by clamping with two clamping plates 31. When it is necessary to move the two clamping plates 31 horizontally, the drive rod 326 can be rotated to drive multiple teeth 327 to mesh with the toothed plate 328, thereby driving the movable frame 321 to slide smoothly along the surface of the fixed plate 325, thus realizing the horizontal displacement of the fixture. This simplifies the positioning operation in the multi-station welding process, ensures the rapid welding of each steel pipe in a horizontal arrangement, and improves welding efficiency and accuracy.

[0033] An electric slide rail 324 is provided on one side of the electric telescopic plate 322. The electric slide rail 324 has two output ends, and the two output ends are fixedly connected to two clamping plates 31 respectively.

[0034] In this embodiment of the utility model, when controlling the two clamping plates 31, the opening and closing actions of the two clamping plates 31 can be controlled by the electric slide rail 324 to achieve rapid clamping and release of the steel pipe.

[0035] A rotary motor 323 is fixedly installed on one side of the electric telescopic plate 322, and the output end of the rotary motor 323 is fixedly connected to one side of the electric slide rail 324.

[0036] In this embodiment of the utility model, the angle of the electric slide rail 324 can be adjusted by the rotary motor 323, thereby synchronously adjusting the angles of the two clamping plates 31 and the steel pipe to meet the process requirements of different welding angles.

[0037] In some embodiments, such as Figure 2 and Figure 5 As shown, the placement assembly 33 includes a tray 331 rotatably mounted on the top of the welding machine 1. Two placement plates 332 are slidably connected to the surface of the tray 331, and grooves are provided on the surface of both placement plates 332.

[0038] In this embodiment of the utility model, the distance between the two placement plates 332 can be adjusted by sliding according to the size of the condenser body to adapt to the placement of condensers of different specifications. The surface of each placement plate 332 is provided with grooves to stabilize the bottom of the condenser and improve the stability of the condenser placement.

[0039] An electric push rod 334 is fixedly installed on the top of the welding machine 1. A connecting block 335 is rotatably installed on the output end of the electric push rod 334. The connecting block 335 is slidably connected to the support plate 331.

[0040] In this embodiment of the utility model, the connecting block 335 can be moved up and down by the extension and retraction of the electric push rod 334, thereby realizing the adjustment of the angle or height of the tray 331.

[0041] A bidirectional screw 333 is rotatably mounted on the surface of the tray 331. The bidirectional screw 333 passes through one side of the two placement plates 332 and is threadedly connected to the two placement plates 332.

[0042] In this embodiment of the invention, by rotating the bidirectional screw 333, the sliding distance of the two placement plates 332 along the surface of the support plate 331 can be adjusted synchronously, thereby precisely adjusting the distance between the two placement plates 332 according to the different size requirements of the refrigerator condenser.

[0043] Rubber plates 336 are fixedly installed inside both placement plates 332, and multiple friction grooves are opened on the adjacent side of the two rubber plates 336.

[0044] In this embodiment of the invention, when the spacing between the two placement plates 332 is adjusted, the condenser can be fixed and clamped by the rubber plate 336 and multiple friction grooves, thereby improving the placement stability of the condenser.

[0045] In this embodiment of the invention, the rotating drive rod 326 can synchronously drive multiple teeth 327 to mesh with the toothed plate 328, thereby driving the movable frame 321 to slide smoothly along the surface of the fixed plate 325, thus achieving horizontal displacement of the clamp. This simplifies the positioning operation in multi-station welding processes, ensures rapid welding of steel pipes in a horizontally arranged state, and improves welding efficiency and accuracy. When controlling the two clamping plates 31, the opening and closing actions of the two clamping plates 31 can be controlled by the electric slide rail 324 to achieve rapid clamping and release of the steel pipes. The angle of the electric slide rail 324 can be adjusted by the rotating motor 323, thereby synchronously adjusting... The angles of the two clamping plates 31 and the steel pipe can be adjusted by rotating the bidirectional screw 333, which can simultaneously adjust the sliding distance of the two placement plates 332 along the surface of the support plate 331. This allows for precise adjustment of the distance between the two placement plates 332 according to the different size requirements of the refrigerator condenser. The extension and retraction of the electric push rod 334 can drive the connecting block 335 to move up and down, thereby achieving adjustment of the angle or height of the support plate 331. The sliding distance of the two placement plates 332 along the surface of the support plate 331 can be adjusted by rotating the bidirectional screw 333, which allows for precise adjustment of the distance between the two placement plates 332 according to the different size requirements of the refrigerator condenser.
