Description

Technical Field

[0001] The invention relates to the technical field of welding equipment, in particular to special equipment for welding a refrigeration evaporator for a ship. Background Art

[0002] The refrigeration evaporator generally consists of structures such as pipes and heat sinks. When in use, the liquid refrigerant is converted into gas here. In physics, this conversion process is called "evaporation", so it is called an evaporator. When the liquid refrigerant evaporates, it absorbs heat, thereby achieving a cooling effect.

[0003] When manufacturing the evaporator, the connection between its pipes is generally carried out by brazing. At present, when welding the evaporator, the brazing wire is wound around the welding part, and then the evaporator to be welded is placed on a conveyor belt, and multiple flame spray guns are set up on both sides of the conveyor belt. When the evaporator on the conveyor belt passes through the flame spray gun, the flame spray gun heats and melts the brazing wire, so that the molten brazing wire connects the pipe to complete the welding. This welding is not only labor-saving, but also efficient. However, when welding, the evaporator just after welding is overheated and requires a long conveyor belt for cooling. The staff can only unload the material after the evaporator after welding is cooled, otherwise the staff will be at risk of burns. Since a long conveyor belt is required for transportation, the current welding equipment requires a larger site for layout, thereby reducing the practicality of the welding equipment.

After the evaporator is conveyed to the position in contact with the clamping plate 17, another telescopic rod 16 is started, so that the other telescopic rod 16 moves with the other clamping plate 17 to the top of the conveyor belt 1, and then the cylinder 19 is started, so that the cylinder 19 pushes one of the telescopic rods 16 and the clamping plate 17 to move, so that the two clamping plates 17 are close to each other, so that the two clamping plates 17 can clamp the conveyed evaporator.

[0027] In the present invention, when in use, firstly, the pallet on which the evaporators are stacked is placed on one side of the track box 4, and then the telescopic rod 16 on the right side thereof is started, so that the telescopic rod 16 drives the clamping plate 17 to move, so that the clamping plate 17 moves to the top of the conveyor belt 1, so that after the welding of the welded evaporator is completed, the evaporator will be conveyed to the position in contact with the clamping plate 17, and after the evaporator is conveyed to the position in contact with the clamping plate 17, another telescopic rod 16 is started, so that the other telescopic rod 16 moves with the other clamping plate 17 to the top of the conveyor belt 1, and then the cylinder 19 is started, so that the cylinder 19 pushes one of the telescopic rods 16 and the clamping plate 17 to move, so as to clamp the conveyed evaporator; After the evaporator is clamped, the second motor 13 is started, so that the second motor 13 drives the screw rod 11 to rotate, and the rotating screw rod 11 drives the slider 12, the connecting block 15, the bottom plate 5, the mounting frame 6 and the clamped evaporator and other components to move. When the evaporator moves to one side of the pallet where the evaporator is stacked, the second motor 13 is stopped, and then the two telescopic rods 16 are started at the same time, so that the two telescopic rods 16 drive the clamping plate 17 and the clamped evaporator to move, so that the evaporator moves to the top of the pallet, and then the first motor 8 is started, so that the first motor 8 drives the threaded rod 9 to rotate, and the rotating threaded rod 9 drives the support plate 7, the clamping mechanism and the clamped evaporator to move downward, and then the evaporator is stacked on the pallet. At this time, the cylinder 19 can be started to reset to loosen the clamping of the evaporator, and then the telescopic rod 16 can be started to reset. After the telescopic rod 16 is reset, the first motor 8 and the second motor 13 can be started to reverse, so that the first motor 8 and the second motor 13 drive the device to reset, so that the device can carry out the unloading of the next evaporator; This unloading method is to unload materials automatically through a mechanical structure, so that the unloading can be carried out without waiting for the evaporator to cool down, and the staff will not be scalded. It not only saves manpower, but also is safe and reliable. At the same time, since there is no need for cooling, a longer conveyor belt 1 needs to be set for conveying and cooling, which reduces the overall length of the device, thereby reducing the space required for the use of the device, making the device more practical. When the two telescopic rods 16 are started at the same time, so that the two telescopic rods 16 drive the clamping plate 17 and the clamped evaporator to move, the moving clamping plate 17 will pull the pull rope 29, so that the pull rope 29 pulls the tray 22, and the moving tray 22 drives the counterweight block 23 to move, so that the counterweight block 23 moves in the opposite direction of the evaporator, and then the counterweight block 23 can automatically balance the uneven weight problem caused by the moving evaporator, so that the device is safer and more reliable when in use, and avoids the problem that the device may tip over due to unbalanced weight.
