Description

Technical Field

[0001] The utility model relates to the technical field of condenser fin welding, in particular to a fin welding device for an automobile condenser. Background Art

[0002] In daily life, air conditioners are used in various places, and in air conditioner units, especially household air conditioners, finned heat exchangers are important components. Finned heat exchangers can be used as evaporators and condensers. Conventional finned condensers are mainly composed of fins and base tubes. The base tubes are inserted into the stacked fins, where the stacked fins are in contact with the air and the base tubes are in contact with the fins. When the refrigerant passes through the base tubes, the refrigerant exchanges heat with the fins through the base tubes and then acts on the air. The fins need to be welded to the outer end of the condenser by a welding device.

[0003] However, when the existing welding device is used to weld the condenser fins, there is a lack of a device for clamping and fixing the fins, so that the welding is unstable and the welding effect is affected.

[0004] For example, in the welding device disclosed in Chinese patent CN202963840U, a chuck is fixedly installed at the end of the rotating shaft. The workpiece to be clamped is clamped with the chuck, and then the workpiece is fixed and clamped with an adjusting bolt to prevent shaking. During welding, the operator rotates the handle at one end to drive the chuck at the right end of the rotating shaft to rotate and adjust it to a suitable welding position for welding. Such welding operation is quick and convenient.

[0005] However, the welding device cannot clamp and fix the condenser and the fins to be welded together before welding, which causes inconvenience in fin welding.

[0006] For this reason, we urgently need to provide a fin welding device for an automobile condenser which can clamp and fix the condenser and the fin together. Utility Model Content

[0007] The utility model aims to provide a fin welding device for an automobile condenser, so as to solve the problem that the welding device proposed in the above background technology cannot clamp and fix the condenser and the fins to be welded together before welding, thus causing inconvenience in fin welding.

[0008] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a fin welding device for a car condenser, comprising a base and a left support plate, the left support plate being fixedly connected to the upper left end of the base, the upper right end of the base being fixedly connected to the right support plate, the outer sides of the upper ends of the left and right support plates being connected to a welding mechanism, the welding mechanism comprising a clamping unit and a purification unit, the clamping unit being arranged at the upper ends of the left and right support plates, and the purification unit being arranged at the upper end of the left support plate.

[0009] The clamping unit includes a telescopic member, a connecting rod, a connecting plate, a top plate, a threaded rod, a handle, a pressure plate and a bottom plate. The telescopic member is fixedly connected to the inner upper end of the right support plate, the connecting rod is fixedly connected to the right upper end of the left support plate, the connecting plate is fixedly connected to the output shaft end of the telescopic member and the side of the connecting rod away from the left support plate, the top plate is fixedly connected to the upper end of the connecting plate away from the telescopic member or the connecting rod, the threaded rod is connected to the inside of the top plate, the handle is fixedly connected to the upper end of the threaded rod, the pressure plate is fixedly connected to the lower end of the threaded rod, and the bottom plate is fixedly connected to the lower end of the connecting plate away from the telescopic member or the connecting rod.

[0010] A further improvement is that a threaded hole is provided in the middle of the top plate, and the outer side of the threaded rod is threadedly connected to the inner side of the threaded hole, so that when the handle is turned to drive the threaded rod in the threaded hole to rotate, the threaded rod can move relative to the top plate.

[0011] A further improvement is that the lower side of the pressing plate and the upper side of the bottom plate abut against the outer sides of the condenser and fins to be welded. Therefore, after the condenser and fins to be welded are placed on the bottom plates at the left and right ends respectively, the handle is turned to drive the threaded rod to rotate and move downward until the pressing plate is driven to move to the upper side of the condenser and the fins, and the condenser and the fins are fixed. Then, the telescopic member is started and its output shaft is extended to drive the connecting plate at the right end to move to the left, and the condenser and the fins are driven to approach and contact the welding position, so that the condenser and the fins are kept fixed at the same time during welding.

[0012] A further improvement is that the purification unit includes a filter box, an activated carbon filter, a HEPA filter, an air intake pipe, an air intake scoop, an exhaust fan and an exhaust pipe, the filter box is fixedly connected to the left upper end of the left support plate, the activated carbon filter is fixedly connected to the inner rear end of the filter box, the HEPA filter is fixedly connected to the middle position of the inner side of the filter box, the air intake pipe is fixedly connected to the rear end of the filter box, the air intake scoop is fixedly connected to the end of the air intake pipe away from the filter box, the exhaust fan is fixedly connected to the upper front end of the left support plate, and the exhaust pipe is fixedly connected to the left end of the exhaust fan.

[0013] A further improvement is that the end of the exhaust pipe away from the exhaust fan is fixedly connected to the front of the inner upper end of the filter box, so that when the exhaust fan is started to exhaust air, air can be sucked from the air intake hopper into the air intake pipe, then into the filter box, and then into the exhaust fan through the exhaust pipe.

[0014] A further improvement is that the end of the air intake hopper away from the air intake pipe is located behind the connecting plate at the upper left end of the base. Therefore, during the welding process, starting the exhaust fan can make the fume generated during welding be sucked into the air intake pipe from the air intake hopper, then enter the filter box, be filtered and purified by the activated carbon filter and the HEPA filter, and then enter the exhaust fan through the exhaust pipe and be discharged, thereby purifying the fume generated during welding.

[0015] A further improvement is that a rubber pad is fixedly connected to the lower side of the pressing plate and the upper side of the bottom plate. Therefore, after the condenser and the fins are fixed between the pressing plate and the bottom plate, the rubber pads on the lower side of the pressing plate and the upper side of the bottom plate contact the outer sides of the condenser and the fins, so that the condenser and the fins can be clamped and fixed more firmly.

[0016] In summary, the present application discloses a fin welding device for an automobile condenser.

[0017] According to the technical solution, after placing the condenser and fins to be welded on the bottom plates at the left and right ends respectively, the handle is turned to drive the threaded rod to rotate and move downward at the same time, until the pressure plate is driven to move to the upper side of the condenser and the fins, the condenser and the fins are fixed, and then the telescopic part is started and its output shaft is extended to drive the connecting plate at the right end to move to the left, and the condenser and the fins are driven close to the welding point and contacted, so that the condenser and the fins can be kept fixed at the same time during welding.

[0018] Furthermore, during the welding process, starting the exhaust fan can allow the fume generated during welding to be sucked into the air intake pipe from the air intake hopper and then enter the filter box to be filtered and purified by the activated carbon filter and the HEPA filter, and then enter the exhaust fan through the exhaust pipe and be discharged, thereby purifying the fume generated during welding.
