Description

Technical Field

[0001] The utility model relates to the technical field of welding, and in particular to a ship stern column welding device. Background Art

[0002] As we all know, welding refers to a processing method that combines welds by heating or pressurizing, or both. According to the different states of the metal during the welding process, welding methods can be divided into three categories: fusion welding, pressure welding and brazing. Among them, arc welding is the most commonly used in fusion welding. In the processing of ship stern columns, fusion welding is mostly used. In the large-scale processing process, repetitive welding work, if only done by manual welding, is not only time-consuming and labor-intensive, but also cannot guarantee the production quality of the product, and greatly increases the labor force of workers. With the development of industry, more and more companies have begun to introduce intelligent welding devices to replace manual welding. In order to ensure the normal processing of ship stern columns, intelligent welding devices are usually used.

[0034] In summary, when the ship stern column welding device is loading the ship stern column 44 to be processed, the ship stern column 44 to be processed is placed inside the rubber loading seat 43, and the motor 41 is started. The motor 41 is a stepping motor. The output end of the motor 41 drives the rotating shaft 40 to rotate, the rotating shaft 40 drives the conveyor belt 42 to rotate, the conveyor belt 42 drives the rubber loading seat 43 to move, and the rubber loading seat 43 drives the ship stern column 44 to be processed to move. Since the motor 41 is a stepping motor, each rotation of the motor 41 just moves the rubber loading seat 43 to the bottom of the clamping claw 23. When the ship stern column 44 to be processed is transported to the bottom of the clamping claw 23, the electric push rod 14 is started, and the output end of the electric push rod 14 drives the push rod box 16 to move. The push rod box 16 drives the clamping mechanism to move downward. When the clamping mechanism moves to the lower part of the stern column 44 to be processed, the electric push rod 17 is started.

The rotating rod 20 drives the adjusting block 21 to move backward. The adjusting block 21 drives the short block 22 to move. The short block 22 drives the clamping claw 23 to move. Due to the rotation restriction of the limit block 24 on the limit column 25, the other ends of the clamping claws 23 are made to move relative to each other. The clamping claws 23 move relative to each other to clamp the stern column 44 to be processed. Then the electric push rod 14 is started. The output end of the electric push rod 14 drives the push rod box 16 to move upward. The push rod box 16 The clamping mechanism is driven to move upward, and the clamping mechanism drives the stern column 44 of the ship to be processed to move upward and leave the rubber loading seat 43, so as to facilitate the automatic material collection of the stern column 44 of the ship to be processed. When the stern column 44 of the ship to be processed is transported, the motor 2 13 is started to make the output end of the motor 2 13 rotate forward, and the output end of the motor 2 13 drives the gear 2 15 to rotate. Since the gear 2 15 is meshed with the tooth plate 2 11, and the tooth plate 2 11 is in a fixed state, the gear 2 15 drives the motor 2 13 to move, and the motor 2 13 drives the conveying seat 12 to move. The movement of the conveying seat 12 drives the electric push rod 1 14, the push rod box 1 16, the clamping mechanism and the stern column 44 of the ship to be processed to move. During the conveying process, the clamping mechanism is in a state where the guide rod 27 is inside the guide groove 26. The position of the guide groove 26 limits the movement of the guide rod 27, so the guide rod 27 drives the turntable 18 to rotate, so that the turntable 18 rotates 90 degrees forward, and the turntable 18 drives the clamping plate 19, the rotating rod 20, the adjusting block 21, the short block 22, the clamping claw 23, the limit block 24, and the limit column 25 to move. The rotation of the clamping claw 23 drives the stern column 44 of the ship to be processed to rotate, and the stern column 44 of the ship to be processed is driven to move to the top of the bearing block 38 through the movement of the conveying plate 3 and the rotation of the turntable 18, and the electric push rod 5 37 is started. The output end of the electric push rod 5 37 drives the bearing block 38 to move upward, so that the bearing groove on the bearing block 38 fits with the bottom end of the stern column 44 of the ship to be processed, and then the electric push rod 2 17 is started to retract the output end of the electric push rod 2 17.The clamping claw 23 is separated from the stern column 44 to be processed, and then the motor 13 is started to reverse the motor 13, and the conveying seat 12 is moved to the state before conveying, so as to facilitate the automatic feeding of the stern column 44 to be processed.

[0035] When the anti-misalignment welding is performed on the stern column 44 of the ship to be processed, the electric push rod 3 29 is started, and the output end of the electric push rod 3 29 drives the anti-misalignment rod 30 to move upward, and the anti-misalignment rod 30 drives the anti-misalignment plate 31 to move, and the anti-misalignment plate 31 drives the electric push rod 4 35, the motor 33, the anti-misalignment block 36 and the like to move upward. When the anti-misalignment block 36 moves to correspond to the stern column 44 of the ship to be processed, the electric push rod 4 35 is started, and the output end of the electric push rod 4 35 drives the anti-misalignment block 36 to move. The anti-misalignment groove matching the stern column 44 of the ship to be processed is opened on the anti-misalignment block 36. The phase movement drives the two stern columns 44 to be processed to move toward each other and then fit and squeeze. Through the extended length of the output end of the electric push rod 4 35, the welding point where the two stern columns 44 to be processed fit together is just below the welding end of the electric welder 7, and then the electric push rod 5 37 is started, and the output end of the electric push rod 5 37 drives the bearing block 38 to move downward, so that the bearing block 38 leaves the stern column 44 to be processed, and the motor 19 is started to make the output end of the motor 19 rotate forward, and the output end of the motor 19 drives the gear 10 to rotate, and the gear 10 drives the tooth plate 18 to move downward, and the tooth plate 18 drives the welding The column 2 5 moves downward, the welding column 2 5 drives the welding plate 6 to move, and the welding plate 6 drives the electric welder 7 to move downward, so that the welding end of the electric welder 7 fits with the welding part of the stern column 44 of the ship to be processed, and the welding part of the stern column 44 of the ship to be processed is welded, and then the motor 33 is started, the output end of the motor 33 drives the gear 4 34 to rotate, the gear 4 34 drives the gear 3 32 to rotate, the gear 3 32 drives the electric push rod 4 35 on the gear 3 32 to rotate, the electric push rod 4 35 drives the anti-misalignment block 36 on the side to rotate, and the anti-misalignment block 36 drives the stern column 44 of the ship to be processed to rotate, It is convenient to use the electric welder 7 to perform comprehensive intelligent welding on the welding joint of the stern column 44 of the ship to be processed. After the welding of the stern column 44 of the ship to be processed is completed, start the motor 9 to reverse the motor 9, restore the electric welder 7 to the state before welding, then stop the motor 33, start the electric push rod 435, so that the output end of the electric push rod 435 drives the anti-dislocation block 36 to leave the stern column 44 of the ship to be processed, and the stern column 44 of the ship to be processed falls onto the receiving rod 45. The processed stern column 44 of the ship to be processed is moved to the inside of the storage box 46 for storage through the guidance of the receiving rod 45.
