Description

Technical Field

[0001] The utility model relates to the technical field of air conditioner radiator welding, in particular to a welding device for an air conditioner radiator with a clamping and fixing structure. Background Art

[0002] The air conditioner radiator is a very important component in the air conditioner. Its main function is to effectively dissipate the heat generated inside the air conditioner to the external environment, thereby ensuring the normal operation of the air conditioner and the regulation of indoor temperature. The air conditioner radiator is usually called a condenser. Its working principle is to transfer heat from the heat source through conduction, convection and radiation. The radiator is generally made of heat-conducting materials, such as aluminum, copper and other metals. These metals have good thermal conductivity and can quickly transfer heat from the heat source to the radiator surface. In the production and assembly process of the air conditioner radiator, a welding device is required to weld the air conditioner radiator, and the clamping and fixing structure is an important component structure in the welding device.

[0003] For example, the Chinese patent "A welding device for a radiator" with announcement number CN206105206U includes a support frame, a cantilever beam is fixedly connected to the upper end of the support frame, a slider is slidably connected to the cantilever beam, a first motor is fixedly connected to one end of the cantilever beam, the first motor is connected to the slider through a ball screw, and the first motor can drive the slider to slide along the cantilever beam through the ball screw, an adjustment mechanism is connected to the slider, a welding gun is connected to the adjustment mechanism, and the adjustment mechanism can drive the welding gun to move along the X-axis and Z-axis, the adjustment mechanism includes an X-axis fixed frame, an X-axis screw rod is connected to the X-axis fixed frame, the upper thread of the X-axis screw rod is connected to the X-axis slider, and the end of the X-axis screw rod is fixedly connected to the X-axis manual wheel, and the welding device also includes a welding frame for placing workpieces to be welded, the welding frame includes a turntable, and two brackets are fixedly connected to the turntable.

[0004] Although the above-mentioned prior art can realize the welding of air-conditioning radiators, in actual use, on the one hand, the adjustment of the clamping and fixing structure is not flexible enough. When welding air-conditioning radiators of different sizes, different clamping structures need to be replaced, resulting in the need to replace the clamping structure every time a different air-conditioning radiator is welded, thereby reducing the adaptability of the clamping structure. On the other hand, the movement of the welding head is not convenient enough. When the welding head welds different positions of the air-conditioning radiator, the operator needs to assist and participate, thereby increasing the workload of the operator. Therefore, it does not meet the existing needs. In this regard, we propose a welding device for an air-conditioning radiator with a clamping and fixing structure. Utility Model Content

[0015] Compared with the prior art, the beneficial effects of the utility model are:

[0016] 1. The utility model can clamp and fix air-conditioning radiators of different sizes through the clamping strips and the extrusion plate. Before the welding operation, the air-conditioning radiator is first placed on the upper end of the fixing seat. At this time, the second bolt is rotated to make the second bolt move through the thread and drive the clamping strip to move together through the second bolt, so that the distance between the clamping strips is reduced until the clamping strip moves to a suitable position and the extrusion plate is above the air-conditioning radiator. Then the first bolt is rotated to make the first bolt move downward through the thread. The first bolt moves and drives the extrusion plate to move downward, and one end of the extrusion plate slides and limits with the limiting groove until the rubber pad at the lower end of the extrusion plate contacts and squeezes the air-conditioning radiator, so that the air-conditioning radiator is fixed to the upper end of the fixing seat, so that the clamping structure can adapt to air-conditioning radiators of different sizes, thereby improving the adaptability of the clamping structure.

[0017] 2. The utility model can flexibly adjust the position of the welding head through the hydraulic telescopic device and the screw rod. When performing welding operations, the air conditioner radiator has been placed and fixed on the fixed seat. At this time, the first motor is turned on, so that the output shaft of the first motor drives the first rotating rod together with the welding head to rotate clockwise. After the first rotating rod is rotated to a suitable position, the hydraulic telescopic device is turned on again, so that the telescopic end of the hydraulic telescopic device extends and drives the second mounting ear plate together with the welding head to move until the welding head moves to a suitable position. Finally, the second motor is turned on, so that the output shaft of the second motor drives the second rotating rod to rotate, and the inclination angle of the welding head is adjusted by the second rotating rod. The welding head is moved in the X-axis direction through the hydraulic telescopic device, and the moving block is moved in the Y-axis direction together with the welding device through the thread on the outside of the screw rod, so that the movement of the welding head is more convenient and flexible, thereby reducing the workload of the operator.

[0018] 3. The utility model can flexibly adjust the position of the air-conditioning radiator through the electric push rod and the third motor. When the welding head is adjusted to a suitable position, the electric push rod is turned on at this time, so that the electric push rod drives the mounting seat to move in the vertical direction, so that the air-conditioning radiator fixed on the fixing seat is moved to contact with the welding head. When the air-conditioning radiator completes a welding operation, the third motor is turned on at this time, so that the output shaft of the third motor drives the fixing seat together with the air-conditioning radiator to rotate until the air-conditioning radiator rotates to the position where the welding operation is required, so that the position adjustment of the air-conditioning radiator is more flexible, thereby avoiding the situation where the air-conditioning radiator needs to be removed and then the position is adjusted.
