Description

Technical Field

[0001] This invention relates to the field of radiator welding technology, specifically to a radiator core and shell welding device and method. Background Technology

[0002] Radiators are an important and basic component of hot water (or steam) heating systems. Hot water is cooled inside the radiator (or steam condenses inside the radiator) to supply heat to the room, achieving the purpose of heating. The metal consumption and cost of radiators account for a considerable proportion of the heating system. Therefore, the correct selection of radiators affects the economic indicators and operating performance of the system. Radiators mainly consist of two parts: the core and the shell. The core includes pipes, heat dissipation fins, etc. The core and the shell are usually fixed by welding.

[0003] When welding the core and shell of a radiator, it is necessary to manually align the ends of the radiator core with the shell one by one, and manual assistance is required to fix the core during the welding process. This time-consuming operation reduces the processing efficiency of the radiator. Therefore, it does not meet the current requirements. To address this, we propose a welding device and method for radiator core and shell. Summary of the Invention

[0004] The purpose of this invention is to provide a welding device and method for a radiator core and a shell, in order to solve the problems mentioned in the background art, which require manual connection of the ends of the radiator core and the shell one by one, and manual assistance in fixing the core during the welding process, resulting in long operation time and reduced radiator processing efficiency.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a radiator core and shell welding device, comprising a fixed base, a robotic arm, and a brazing gun. The robotic arm is fixed to the surface of the fixed base, and the brazing gun is mounted on the top of the robotic arm. Two symmetrically distributed support plates are fixed to the surface of the fixed base. Core clamps are fixed to the inner sides of both ends of the fixed base. The core clamps include two movable electric telescopic rods. One end of the two movable electric telescopic rods is fixed to the fixed base, and the other end of the movable electric telescopic rods is fixed to a connecting block. A movable frame is fixed between the two connecting blocks. Multiple sets of first clamping plates and second clamping plates for clamping are installed on the inner side of the movable frame. The first clamping plates and second clamping plates are used to clamp and fix the end of the radiator core.

[0006] A radiator housing clamp is provided between the movable frame and the end of the fixed base. The radiator housing is clamped and fixed using the radiator housing clamp, and the radiator housing is assembled with the radiator core which is clamped and fixed by the first clamping plate and the second clamping plate using the radiator housing clamp.

[0007] Preferably, multiple fixed blocks with equal vertical spacing are fixed to the inner sides of both ends of the movable frame, and a double-headed adjustable electric telescopic rod is fixedly installed through the inside of each fixed block. The two ends of the double-headed adjustable electric telescopic rod are respectively fixed to the ends of the first clamping plate and the second clamping plate.

[0008] Preferably, the two ends of the first clamping plate and the second clamping plate are horizontal while the middle part is wavy and bent, and a connecting protrusion is provided on one side of the end of the first clamping plate and the second clamping plate.

[0009] Preferably, the connecting protrusion is semi-circular with a radius larger than the diameter of the movable end of the double-headed adjustable electric telescopic rod, and the end of the double-headed adjustable electric telescopic rod is fixed to the connecting protrusion.

[0010] Preferably, the radiator housing clamp includes an assembly electric telescopic rod, which is located between two movable electric telescopic rods and fixed to a fixed base, and a support frame is fixed to the movable end of the assembly electric telescopic rod.

[0011] Preferably, the support frame has four ends and is X-shaped, with connecting rods fixed to the surfaces of the support frame ends facing the movable frame, and electromagnets fixed to the ends of the connecting rods away from the support frame.

[0012] Preferably, the electromagnet has a right-angle slot on its inner side, and the depth of the right-angle slot is the same as the thickness of the radiator housing.

[0013] Preferably, a plurality of core placement bearing plates are fixed between two symmetrically distributed support plates, with equal vertical spacing between them, and the spacing between adjacent core placement bearing plates is greater than or equal to the spacing between the cores of two adjacent finished radiators.

[0014] Preferably, the core placement support plate includes a support layer plate, the surface of which is provided with a plurality of positioning grooves and fin snap-fit ​​grooves. The positioning grooves are distributed in a linear array along the length direction of the support layer plate, and the fin snap-fit ​​grooves are distributed in a linear array along the width direction of the support layer plate.

[0015] A method of using a welding device for a radiator core and a housing includes the following steps:

[0016] S1: First, place the radiator core inside the positioning groove on the surface of the support plate;

[0017] S2: Then, the four corners of the radiator housing are respectively snapped into the right-angle slots inside the four electromagnets, and the power supply of the electromagnets is turned on, so that the electromagnets electromagnetically attract the radiator housing.

[0018] S3: When the mobile electric telescopic rod is powered on, it drives the connecting block and the moving frame to move, so that the first clamping plate and the second clamping plate move with the moving frame and surround the end of the radiator core from the top and bottom.

[0019] S4: The double-headed adjustable electric telescopic rod is energized and its ends extend out. The first clamping plate and the second clamping plate move closer to the radiator core and clamp the radiator core.

[0020] S5: When the electric telescopic rod is powered on, it drives the support frame, connecting rod and electromagnet to move, so that the radiator shell contacts the radiator core, and the radiator core passes through the mounting hole on the surface of the radiator shell;

[0021] S6: Finally, the end of the radiator core that passes through the radiator housing is welded and fixed using the brazing gun at the top of the robotic arm.

[0022] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0023] 1. This invention uses a first clamping plate and a second clamping plate to clamp the end of the radiator core, then uses a radiator housing clamp to fix the radiator housing, and then assembles the fixed radiator housing with the clamped radiator core through the radiator housing clamp. Finally, the brazing gun at the top of the robotic arm is used to weld and fix the end of the radiator core that passes through the radiator housing, which shortens the assembly time of the core and the housing, and no manual assistance is required during the welding process, thus shortening the welding time and improving the welding efficiency.

[0024] 2. The present invention uses positioning grooves to position the heat sink core, ensuring uniform spacing between adjacent heat sink cores, while fin snap-fit ​​grooves are used to snap and fix the outer fins of the heat sink core, thereby ensuring that the heat sink core will not shift in the axial direction after placement.

[0025] 3. This invention utilizes four electromagnets to magnetically attract and fix the end corners of the radiator housing, thereby clamping the radiator housing. Subsequently, the movement of the radiator housing is controlled by assembling an electric telescopic rod, a support frame, and a connecting rod, thus completing the assembly of the radiator housing and the radiator core.
