Description

Technical Field

[0001] The invention relates to the technical field of fire damper production, and in particular to a laser welding positioning device for fire damper production. Background Art

[0002] The fire damper is one of the important components in the fire protection system. Its working principle is to adjust the air circulation by controlling the rotation of the fan blades. The connection between the fan blades and the rotating shaft must be firm and reliable, otherwise it may cause the valve to fail in emergency situations such as fire, resulting in serious consequences. Therefore, in the production of fire dampers, the fixed connection between the fan blades and the rotating shaft is a key link to ensure product quality. The two existing welding methods between the fan blades and the rotating shaft have some problems. For example, the first method uses a manual handheld welding gun to spot weld the welding position, but the spot welding method cannot seal the weld between the fan blade and the rotating shaft, resulting in the fire damper being unable to be completely sealed in the closed state. The first method is to manually install a clip at the welding point between the fan blade and the rotating shaft and weld the clip, but in the production process, the clip is welded to the side wall of the fan blade, which can easily cause the fan blade to deform, causing friction against the inner wall of the outer frame when the fan blade is closed and opened, or the fan blade cannot be opened and closed, resulting in the problem that the fire damper cannot be used. The above two methods are both welded manually, and manual welding cannot guarantee the precision and accuracy of welding, so that during the use of the fire damper, the connection between the fan blade and the rotating shaft is poor and cannot meet the use of emergency situations.

[0013] Compared with the prior art, the advantages of the present invention are:

[0014] 1. The present invention cooperates between push plates 1 and 2. When installing the rotating shaft, the motor 3 is started and the bidirectional screw 1 is rotated, so that the push rod 1 and the push rod 2 move relative to each other. The push rod 1 and the push rod 2 drive the push plates 1 and the push rod 2 to squeeze the fan blades. During the squeezing process, the telescopic rod 2 contracts, so that the push plates 1 and the push plates 2 drive the fan blades to rotate. When the bidirectional screw 1 drives the push plates 1 and the push rods 2 to contract by rotating, the telescopic rod 2 contacts the side walls of the push plates 1 and the push plates 2, so that the push plates 1 and the push plates 2 drive the fan blades to return to their original positions. The push plates 1 and the push plates 2 drive the fan blades to swing back and forth, thereby improving the installation efficiency of the rotating shaft and avoiding the problem of damaging the inner walls of the fan blades when installing the rotating shaft.

[0015] 2. The present invention cooperates between the push rod 2 and the movable plate 1. When the rotating shaft is installed, the push rod 2 drives the push plate 2 to rotate, and the push rod 1 contacts the side wall of the movable plate 1, so that the movable plate 1 drives the welding frame to slide along the locking rod toward the push plate 2, and the locking block 1 contacts the locking block 2 and then contracts. When the push rod 1 moves away from the movable plate 1, the movable plate 1 stops moving, and the side wall of the locking block 1 312 contacts the side wall of the locking block 2 332. At this time, the movable plate 1 31 is locked, and the rotating shaft slides into the inner wall of the outer frame. The welding frame drives the welding gun 1 and the welding gun 2 to move between the fan blade and the rotating shaft. The welding gun 1 and the welding gun 2 are driven by the movable plate 1 to move between the fan blade and the rotating shaft, so that the welding gun 1 and the welding gun 2 are positioned on the welding range between the rotating shaft and the fan blade, thereby reducing manual intervention and improving production efficiency.

[0016] 3. The present invention cooperates between the rotating shaft and the roller. When the rotating shaft is installed, the movable plate 1 contacts the side wall of the push plate 2 through the push rod 1. After the rotating shaft slides above the welding gun 1 and the welding gun 2, the push plate 2 and the push plate 1 drive the fan blade to rotate, and the roller contacts the side wall of the rotating shaft and rolls. The roller drives the gear rod to rotate, and the gear rod drives the welding gun 1 and the welding gun 2 to move relatively, so that the rotating shaft enters the interior of the fan blade. At the same time, the welding gun 1 and the welding gun 2 move to the weld between the rotating shaft and the fan blade. At this time, the roller slides on the outside of the rotating shaft. When the rotating shaft is installed, the welding gun 1, the welding gun 2 and the motor 5 are started to weld the rotating shaft and the fan blade. The welding gun 1 and the welding gun 2 are driven to move by the rolling of the roller on the outside of the rotating shaft, so that the welding gun 1 and the welding gun 2 can position the weld between the rotating shaft and the fan blade, thereby reducing manual intervention and improving production efficiency.
