Description

Technical Field

[0001] This utility model relates to the field of welding equipment technology, and in particular to a welding equipment for a compressor liquid receiver. Background Technology

[0002] The compressor receiver is a crucial component of a refrigeration system, its primary function being to store refrigerant and ensure a stable refrigerant supply during system operation. In compressor manufacturing, the welding process of the receiver is a critical step, directly impacting the compressor's quality and performance.

[0003] The welding of compressor receivers commonly employs flame brazing in the industry, using combustible gas as fuel and oxygen as an oxidizer. The welding wire is brought to its melting point before welding. However, flame brazing presents several challenges: First, temperature control is difficult, resulting in a large heat-affected zone. It relies heavily on the operator's control over flame size, distance, and timing, requiring a high level of skill. Second, the high temperatures during flame brazing easily oxidize the metal surface. Furthermore, if the brazing filler metal or base material contains oil, oxides, or other impurities, porosity or other defects can easily form in the weld, directly impacting weld strength. Finally, flame brazing is energy-intensive and causes some environmental pollution. Utility Model Content

[0004] Based on this, the purpose of this utility model is to overcome the shortcomings of the prior art and provide a compressor liquid receiver welding device that uses the resistance heating effect of electric current to heat the welding area, ensuring a stable welding process, high weld quality, and no pollution.

[0005] To achieve the above objectives, this utility model provides a compressor liquid receiver welding device, including a support base, a clamping mechanism, a hot wire feeding mechanism, and a welding wire heating mechanism.

[0006] The support base is used to support the compressor and the liquid receiver, and the clamping mechanism is used to clamp the liquid receiver supported on the support base; the hot wire feeding mechanism is used to feed the welding wire to the connection between the compressor and the liquid receiver and preheat the welding wire; the welding wire heating mechanism is used to heat the welding wire at high frequency so that the compressor and the liquid receiver are welded together.

[0007] As one implementation, it also includes a frame and a rotating table, the rotating table being rotatably mounted on the frame, the bearing base being fixedly mounted on the rotating table, and the pressing mechanism, the hot wire feeding mechanism, and the welding wire heating mechanism being respectively mounted on the frame.

[0008] In one embodiment, the top of the support base is provided with an arc-shaped support portion, which is used to support the compressor.

[0009] In one embodiment, the clamping mechanism includes a clamping lifting motor and a clamping part. The clamping part is disposed at the output end of the clamping lifting motor, and the bottom of the clamping part is provided with an arc-shaped clamping port. The clamping lifting motor is used to drive the clamping part to perform lifting and lowering movements, so that the clamping part can clamp or loosen the liquid reservoir supported on the support base.

[0010] In one embodiment, the hot wire feeding mechanism includes a wire feeding lifting motor, a wire feeding base, a preheating coil, a welding wire connecting tube, and a wire guide gun. The wire feeding base is disposed at the output end of the wire feeding lifting motor, the welding wire connecting tube is disposed on the wire feeding base, the preheating coil is disposed on the wire feeding base and preheats the welding wire connecting tube, and the wire guide gun is disposed on the wire feeding base and connected to the welding wire connecting tube.

[0011] In one embodiment, a servo motor is provided on the wire feeding base, and the wire guide gun is located at the output end of the servo motor.

[0012] In one embodiment, the welding wire heating mechanism includes a welding wire heating base, a high-frequency coil, and a coil drive motor. The coil drive motor is disposed on the welding wire heating base, and the high-frequency coil is disposed at the output end of the coil drive motor. The coil drive motor is used to drive the high-frequency coil to the connection between the compressor and the liquid receiver, and to heat the welding wire at high frequency through the high-frequency coil so that the compressor and the liquid receiver are welded together.

[0013] In one embodiment, a rotary motor is provided on the frame, and the rotary table is mounted on the rotary motor.

[0014] In one embodiment, a plurality of bearing bases are provided at intervals along the circumferential direction on the rotating platform.

[0015] Therefore, the compressor receiver welding equipment according to this utility model embodiment can perform processes such as loading, preheating, wire feeding, heating welding, and unloading via a rotary table. Specifically, the compressor and receiver are placed on a support base, and the compressor housing is fixed on the support part of the support base. The receiver is located at the top of the compressor away from the support part. Then, the support base is rotated to below the clamping mechanism via the rotary table. The clamping lifting motor drives the clamping part to move up and down, so that the receiver is clamped. Then, the preheating coil of the hot wire feeding mechanism preheats the welding wire connecting tube, so that the welding... The welding wire in the connecting tube is preheated, and then the wire feeding lifting motor drives the wire guide gun to the connection between the compressor and the liquid receiver. A coil drive motor drives a high-frequency coil to the nozzle of the wire guide gun, subjecting the welding wire at the nozzle to high-frequency heating. This rapidly melts the metal welding wire, thus achieving welding and fixing between the compressor and the liquid receiver. During welding, a servo motor drives the wire guide gun, feeding the welding wire in an arc-shaped oscillating motion. This method, compared to direct wire feeding, results in a more uniform molten pool, directly improving the weld formation quality and reducing welding defects. In other words, the compressor-liquid receiver welding equipment according to this embodiment uses high-frequency welding to weld the connection between the compressor and the liquid receiver. This results in a small heat-affected zone, effectively reducing material deformation and stress concentration, improving weld strength and sealing performance. Furthermore, the welding speed is fast, the weld is uniform, and the welding process is stable. It also eliminates the need for flux or shielding gas, effectively reducing the emission of harmful gases and waste, making it more environmentally friendly, energy-efficient, and in line with the trend of green manufacturing.

[0024] In related technologies, flame brazing is commonly used in the industry for welding compressor receivers. This process uses combustible gas as fuel and oxygen as an oxidizer, allowing the welding wire to reach its melting point before welding. However, flame brazing presents several challenges: First, temperature control is difficult, resulting in a large heat-affected zone. It relies heavily on the operator's control over flame size, distance, and timing, requiring a high level of skill. Second, the high temperatures during flame brazing easily oxidize the metal surface. Furthermore, if the brazing filler metal or base material contains oil, oxides, or other impurities, these can create porosity or other defects in the weld, directly impacting weld strength. Finally, flame brazing is energy-intensive and causes some environmental pollution.

[0025] In view of this, the present invention provides a compressor receiver welding device. The compressor receiver welding device according to the present invention utilizes the resistance heating effect of electric current to heat the welding area, ensuring a stable welding process, high weld quality, and no pollution.

[0026] Please see Figures 1 to 2 This utility model provides a compressor receiver welding device, including a support base, a clamping mechanism 10, a hot wire feeding mechanism 20, and a welding wire heating mechanism. The support base supports the compressor and the receiver, and the clamping mechanism 10 clamps the receiver supported on the support base. The hot wire feeding mechanism 20 feeds the welding wire to the connection between the compressor and the receiver and preheats the welding wire. The welding wire heating mechanism heats the welding wire at high frequency so that the compressor and the receiver are welded together.

[0027] Furthermore, in this embodiment of the invention, the compressor receiver welding equipment also includes a frame and a rotary table. The rotary table is rotatably mounted on the frame, and the bearing base is fixedly mounted on the rotary table. The clamping mechanism 10, the hot wire feeding mechanism 20, and the welding wire heating mechanism are respectively mounted on the frame. A rotary motor is mounted on the frame, and the rotary table is mounted on the rotary motor. A plurality of bearing bases are spaced apart along the circumferential direction on the rotary table. This allows the rotary motor to drive the rotary table to rotate, and the spaced bearing bases on the rotary table separate the loading, observation, and unloading stations, making production and processing more convenient.

[0028] Specifically, in this embodiment of the invention, the top of the support base is provided with an arc-shaped support portion, which is used to support the compressor. Since the compressor housing is a cylindrical structure, the arc-shaped support portion can be designed to fit snugly against the compressor housing, allowing the compressor housing to be placed securely on the support portion. Furthermore, the clamping mechanism 10 includes a clamping lifting motor 11 and a clamping part 12. The clamping part 12 is located at the output end of the clamping lifting motor 11, and its bottom has an arc-shaped clamping opening. The clamping lifting motor 11 drives the clamping part 12 to move up and down, allowing the clamping part 12 to clamp or release the liquid reservoir supported on the support base. In other words, when the rotary table rotates the compressor and liquid reservoir on the support base to below the clamping mechanism 10, the clamping lifting motor 11 drives the clamping part 12 to press against the liquid reservoir, temporarily fixing the liquid reservoir and compressor in place to facilitate welding operations between them.

[0029] In this embodiment of the invention, the hot wire feeding mechanism 20 includes a wire feeding lifting motor, a wire feeding base 21, a preheating coil 24, a welding wire connecting tube, and a wire guide gun 22. The wire feeding base 21 is disposed at the output end of the wire feeding lifting motor, the welding wire connecting tube is disposed on the wire feeding base 21, the preheating coil 24 is disposed on the wire feeding base 21 and preheats the welding wire connecting tube, and the wire guide gun 22 is disposed on the wire feeding base 21 and connected to the welding wire connecting tube. A servo motor 23 is disposed on the wire feeding base 21, and the wire guide gun 22 is disposed at the output end of the servo motor 23. In addition, the welding wire heating mechanism includes a welding wire heating base, a high-frequency coil, and a coil drive motor. The coil drive motor is disposed on the welding wire heating base, and the high-frequency coil is disposed at the output end of the coil drive motor. The coil drive motor is used to drive the high-frequency coil to the connection between the compressor and the liquid receiver, and to heat the welding wire at high frequency through the high-frequency coil so that the compressor and the liquid receiver are welded together.

[0030] Therefore, according to the compressor receiver welding equipment of this utility model embodiment, the rotary table can perform processes such as feeding, preheating, wire feeding, heating welding, and unloading. Specifically, the compressor and receiver are placed on the support base, and the compressor housing is fixed on the support part of the support base. The receiver is located on the top of the compressor away from the support part. Then, the rotary table rotates the support base to below the clamping mechanism 10. The clamping lifting motor 11 drives the clamping part 12 to move up and down, so that the receiver is clamped by the clamping part 12. Then, the preheating coil 24 of the hot wire feeding mechanism 20 preheats the welding wire connecting tube, so that... The welding wire in the welding wire connecting tube is preheated, and then the wire feeding lifting motor drives the wire guide gun 22 to the connection between the compressor and the liquid receiver. A coil drive motor drives a high-frequency coil to the nozzle of the wire guide gun 22, subjecting the welding wire at the nozzle to high-frequency heating. This causes the metal welding wire to melt rapidly, thus achieving welding and fixing between the compressor and the liquid receiver. During welding, a servo motor 23 drives the wire guide gun 22 to move, feeding the welding wire in an arc-shaped oscillating manner. This method, compared to direct wire feeding, results in a more uniform molten pool, directly improving the weld formation quality and reducing welding defects. In other words, the compressor-liquid receiver welding equipment according to this embodiment uses high-frequency welding to weld the connection between the compressor and the liquid receiver. This results in a small heat-affected zone, effectively reducing material deformation and stress concentration, improving welding strength and sealing performance. Furthermore, the welding speed is fast, the weld is uniform, and the welding process is stable. It also eliminates the need for flux or shielding gas, effectively reducing the emission of harmful gases and waste, making it more environmentally friendly, energy-efficient, and in line with the trend of green manufacturing.

[0031] The above-described embodiments are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the welding equipment for the compressor receiver of this utility model. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these modifications and improvements all fall within the protection scope of this utility model.
