Technical Field
[0001] The present invention relates to the technical field of welding, in particular to a curved beam welding device for shipbuilding. Background Art
[0002] In shipbuilding, curved beams are key structural components, and their welding quality directly affects the strength and stability of the hull. The curved beam welding device is a special equipment designed for the welding needs of curved beams, which achieves precise welding through mechanical structure and automated control.
[0003] When welding a curved beam, the welding equipment will apply a downward welding force to the curved beam, which will cause the welding point of the curved beam to be subjected to downward pressure, resulting in the side of the curved beam to warp. The side warping will cause the joint gap at the welding point of the curved beam to change, resulting in the welding position of the curved beam to shift, which will affect the normal use of the curved beam. In response to the above problems, the following solutions are proposed.
[0004] Based on this, the present invention discloses a curved beam welding device for shipbuilding. Summary of the Invention
[0005] In order to solve the problem proposed in the background technology that when welding a curved beam, the welding equipment will apply a downward welding force to the curved beam, which will cause the welding point of the curved beam to be subjected to downward pressure, thereby causing the side of the curved beam to warp, and the warping of the side will cause the joint gap of the curved beam welding point to change, the present invention provides a curved beam welding device for shipbuilding, which includes a base, and the base also includes a welding mechanism, the top of the base is fixedly connected to a bottom plate, the side of the bottom plate away from the base is fixedly connected to an electric telescopic rod, one end of the electric telescopic rod away from the bottom plate is fixedly connected to the welding equipment, the side of the welding equipment and the bottom plate close to each other is fixedly connected to an air collecting bag, the top of the base is fixedly connected to a telescopic tube, the outer wall of the telescopic tube is fixedly connected to a connecting tube, the end of the connecting tube away from the telescopic tube is fixedly connected to the outer wall of the air collecting bag, and the end of the telescopic tube away from the base is fixedly connected to a push rod; The top of the two support bars is fixedly connected to the base, and one end of the support bar is fixedly connected to the top of the two support bars. The top of the two support bars is fixedly connected to the top of the two support bars. The top of the two support bars is fixedly connected to the top of the two support bars. The top of the two support bars is fixedly connected to the top of the two support bars. As a further improvement of the present technical solution, when the device needs to be used to weld the curved beams, the two curved beams to be welded are first placed on the top of the two curved plates respectively. Under the action of the baffle, the curved beams placed on the top of the curved plates can be prevented from sliding. After the curved beams are placed, the electric telescopic rod is started, and the electric telescopic rod drives the welding equipment to move downward to weld the two curved beams. During the process of the electric telescopic rod driving the welding equipment to move downward, an extrusion force is applied to the air bag, thereby forcing the gas in the air bag to enter the telescopic tube through the connecting tube. The gas entering the telescopic tube causes the telescopic tube to expand, thereby causing the telescopic tube to drive The push rod moves upward, and during the upward movement of the push rod, it drives the connecting plate, strip plate and push plate to move upward synchronously. After the push plate moves upward, it drives the push rod upward, and the push rod moves upward and contacts the limit plate, forcing the limit plate to rotate with the rotating rod as the midpoint. The rotation of the limit plate can fix the top of the arc beam, which can prevent the downward welding force from lifting the arc beam when the welding equipment welds the arc beam, and fix the top of the arc beam. The stable clamping of the limit plate can prevent dimensional deviation caused by welding deformation, avoid waste of materials and working hours due to scrapping of workpieces, and can improve the stability and accuracy of the arc beam during welding.
[0006] On this basis, since the position of the curved beam will be inconsistent when it is placed on the top of the curved plate, the curved beam will not be in the center position. In order to avoid the situation where the position of the curved beam is not accurate and the welding position is offset when welding the curved beam; As a further improvement of the present technical solution, when the limit plate rotates with the rotating rod as the midpoint, the rotation of the rotating rod drives the gear to rotate, and the gear engages with the rack, so that the rotation of the gear drives the rack to move, and the rack drives the clamping plate to move toward the arc-shaped beam during the movement. The multiple clamping plates cooperate with each other and approach each other to clamp and fix the arc-shaped beam. Through the precise transmission of the gear and the rack, the rotational motion of the limit plate is converted into the horizontal linear motion of the clamping plate, forming a multi-point coordinated clamping fixing effect. By clamping multiple clamping plates from the side at the same time and fixing from the top with the limit plate, a three-dimensional constraint is formed, thereby further improving the accuracy of arc-shaped beam welding and improving the quality of arc-shaped beam welding.
[0007] In another solution, when the welding equipment moves downward to weld the two curved beams, the welding part of the two curved beams will be subjected to downward pressure, and the two curved beams will bend at the welding part due to the pressure. In order to avoid the influence of the downward pressure of the welding equipment on the welding of the curved beams, As a further improvement of the present technical solution, during the upward movement of the push rod, the push rod drives the connecting bar to move upward, and during the upward movement of the connecting bar, the arc-shaped top plate is driven to move upward. When the welding equipment moves downward to weld the two arc-shaped beams, the welding points of the two arc-shaped beams are subjected to downward pressure. By supporting the welding points of the two arc-shaped beams by the upward movement of the arc-shaped top plate, the pressure on the two arc-shaped beams can be reduced, and an upward supporting force can be provided for the welding points of the two arc-shaped beams. The upward supporting force provided by the arc-shaped top plate can directly offset the downward pressure stress of the welding equipment, thereby reducing the error in welding the arc-shaped beams, ensuring the dimensional accuracy of the welded parts, and meeting high-precision welding requirements.
[0008] Compared with the prior art, the present invention has the following beneficial effects: 1. In the arc beam welding device for shipbuilding, when the device needs to be used to weld the arc beam, first, the two arc beams to be welded are placed on the top of the two arc plates respectively. Under the action of the baffle, the arc beams placed on the top of the arc plates can be prevented from sliding. After the arc beams are placed, the electric telescopic rod is started, and the electric telescopic rod drives the welding equipment to move downward to weld the two arc beams. During the process of the electric telescopic rod driving the welding equipment downward, an extrusion force is applied to the air bag, thereby forcing the gas in the air bag to enter the telescopic tube through the connecting tube. The gas entering the telescopic tube causes the telescopic tube to expand, thereby making the telescopic tube The tube drives the push rod to move upward, and in the process of the push rod moving upward, it drives the connecting plate, strip plate and push plate to move upward synchronously. After the push plate moves upward, it drives the push rod to move upward, and the push rod moves upward and contacts the limit plate, forcing the limit plate to rotate with the rotating rod as the midpoint. The rotation of the limit plate can fix the top of the arc beam, which can prevent the downward welding force from lifting the arc beam when the welding equipment welds the arc beam, and fix the top of the arc beam. The stable clamping of the limit plate can prevent dimensional deviation caused by welding deformation, avoid waste of materials and working hours due to scrapping of workpieces, and can improve the stability and accuracy of the arc beam during welding.
[0009] 2. In the arc-beam welding device for shipbuilding, when the limit plate rotates with the rotating rod as the midpoint, the rotation of the rotating rod drives the gear to rotate, and the gear is engaged with the rack, so that the rotation of the gear drives the rack to move, and the rack drives the clamping plate to move toward the arc-beam during the movement. The multiple clamping plates cooperate with each other and approach each other to clamp and fix the arc-beam. Through the precise transmission of the gear and the rack, the rotational motion of the limit plate is converted into the horizontal linear motion of the clamping plate, forming a multi-point coordinated clamping fixing effect. By clamping the multiple clamping plates from the side at the same time and fixing from the top with the limit plate, a three-dimensional constraint is formed, thereby further improving the accuracy of arc-beam welding and improving the quality of arc-beam welding.
[0010] 3. In the arc-beam welding device for shipbuilding, during the upward movement of the push rod, the push rod drives the connecting bar to move upward, and during the upward movement of the connecting bar, the arc-shaped top plate is driven to move upward. When the welding equipment moves downward to weld the two arc-beams, the welding points of the two arc-beams are subjected to downward pressure. The arc-shaped top plate moves upward to support the welding points of the two arc-beams, which can reduce the pressure on the two arc-beams and provide an upward supporting force for the welding points of the two arc-beams. The upward supporting force provided by the arc-shaped top plate can directly offset the downward pressure stress of the welding equipment, thereby reducing the error in welding the arc-beams, ensuring the dimensional accuracy of the welded parts, and meeting the requirements of high-precision welding.

[0013] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.
[0014] Currently, when welding the curved beam 115, the welding equipment applies a downward welding force to the curved beam 115, which causes the welding point of the curved beam 115 to be subjected to downward pressure, thereby causing the side of the curved beam to warp. The warping of the side will cause the joint gap of the welding point of the curved beam 115 to change.
[0015] To this end, the present invention provides a curved beam welding device for shipbuilding. Figure 9 and Figure 10 As shown, it includes a base 101, and the base 101 also includes a welding mechanism 1. The top of the base 101 is fixedly connected to a bottom plate 102, and the side of the bottom plate 102 away from the base 101 is fixedly connected to an electric telescopic rod 103, and the end of the electric telescopic rod 103 away from the bottom plate 102 is fixedly connected to a welding device 104, and the side of the welding device 104 and the bottom plate 102 close to each other is fixedly connected to an air collecting bag 105, and the top of the base 101 is fixedly connected to a telescopic tube 106, and the outer wall of the telescopic tube 106 is fixedly connected to a connecting tube 107, and the end of the connecting tube 107 away from the telescopic tube 106 is fixedly connected to the outer wall of the air collecting bag 105, and the end of the telescopic tube 106 away from the base 101 is fixedly connected to a push rod 108.
[0016] For details, see Figure 2 、 Figure 3 、 Figure 5 and Figure 6 As shown, a connecting plate 109 is fixedly connected to the outer wall of the push rod 108, and a plurality of strip plates 110 are fixedly connected to the outer wall of the connecting plate 109. The sides of the plurality of strip plates 110 away from each other are respectively fixedly connected to push plates 111, and the tops of the plurality of push plates 111 are respectively fixedly connected to two top rods 112. The top of the base 101 is fixedly connected to two support rods 113, and the ends of the two support rods 113 away from the base 101 are respectively fixedly connected to arc plates 114. The tops of the two arc plates 114 are respectively provided with arc beams 115. The top of 114 is fixedly connected with a baffle 116, and the top of the arc plate 114 is fixedly connected with several fixed blocks 117. A movable groove 118 is provided on the fixed block 117. A rotating rod 119 is rotatably connected in the movable groove 118. The rotating rod 119 extends to the outside of the fixed block 117 and is rotatably connected to the fixed block 117. The outer wall of the rotating rod 119 is fixedly connected to a limit plate 120. The top of the limit plate 120 is fixedly connected with two return springs 121, and the ends of the two return springs 121 away from the limit plate 120 are fixedly connected to the outer wall of the fixed block 117.
[0017] During operation, the electric telescopic rod 103 is started, and the electric telescopic rod 103 drives the welding device 104 to move downward to weld the two arc beams 115. During the process of driving the welding device 104 downward, the electric telescopic rod 103 applies an extrusion force to the air bag 105, thereby forcing the gas in the air bag 105 to enter the telescopic tube 106 through the connecting tube 107. The gas entering the telescopic tube 106 causes the telescopic tube 106 to expand, thereby causing the telescopic tube 106 to drive the push rod 108 to move upward. During the process of the push rod 108 moving upward, the connecting plate 109, the strip plate 110 and the push plate 111 are driven to move upward synchronously. The push plate 111 After moving upward, the push rod 112 is driven to move upward. The push rod 112 moves upward and contacts the limit plate 120, forcing the limit plate 120 to rotate with the rotating rod 119 as the midpoint. The rotation of the limit plate 120 can fix the top of the arc beam 115, thereby preventing the arc beam 115 from tilting due to the downward welding force when the welding equipment 104 welds the arc beam 115. The top of the arc beam 115 is fixed and limited. The stable clamping of the limit plate 120 can prevent dimensional deviation caused by welding deformation, avoid waste of materials and work time due to scrapping of workpieces, and improve the stability and accuracy of the arc beam 115 during welding.
[0018] For further information, see Figure 5 and Figure 6 As shown, the extended end of the rotating rod 119 is fixedly connected to the gear 122, the top of the fixed block 117 is fixedly connected to the connecting rod 123, the end of the connecting rod 123 away from the fixed block 117 is fixedly connected to the slide rail 124, the side of the slide rail 124 away from the connecting rod 123 is slidably connected to the rack 125, the rack 125 is meshed with the gear 122, and the side of the rack 125 away from the slide rail 124 is fixedly connected to the clamping plate 126, and the side wall of the clamping plate 126 is in contact with the arc beam 115.
[0019] During operation, when the limit plate 120 rotates with the rotating rod 119 as the midpoint, the rotating rod 119 rotates to drive the gear 122 to rotate, and the gear 122 engages with the rack 125, so that the gear 122 rotates to drive the rack 125 to move, and the rack 125 drives the clamping plate 126 to move toward the arc beam 115 during the movement. Multiple clamping plates 126 cooperate with each other and approach each other to clamp and fix the arc beam 115. Through the precise transmission of the gear 122 and the rack 125, the rotational movement of the limit plate 120 is converted into horizontal linear movement of the clamping plate 126, forming a multi-point coordinated clamping fixing effect. By clamping multiple clamping plates 126 from the side at the same time and cooperating with the limit plate 120 to be fixed from the top, a three-dimensional constraint is formed, thereby further improving the accuracy of welding the arc beam 115 and improving the quality of welding the arc beam 115.
[0020] Among them, see Figure 7 and Figure 8As shown, the bottom of the arc-shaped plate 114 is fixedly connected to a support plate 127, the support plate 127 is slidably connected to the push rod 108, the top of the push rod 108 is fixed with a connecting strip 128, and the side of the connecting strip 128 away from the push rod 108 is fixedly connected to an arc-shaped top plate 129.
[0021] During operation, as the push rod 108 moves upward, the push rod 108 drives the connecting bar 128 to move upward, and as the connecting bar 128 moves upward, it drives the arc-shaped top plate 129 to move upward. When the welding equipment 104 moves downward to weld the two arc beams 115, the welding points of the two arc beams 115 are subjected to downward pressure. By supporting the welding points of the two arc beams 115 by moving the arc-shaped top plate 129 upward, the pressure on the two arc beams 115 can be reduced, and an upward supporting force can be provided for the welding points of the two arc beams 115. The upward supporting force provided by the arc-shaped top plate 129 can directly offset the downward pressure stress of the welding equipment 104, thereby reducing the error in welding the arc beams 115, ensuring the dimensional accuracy of the welded parts, and meeting high-precision welding requirements.
[0022] In summary, the present invention effectively solves the problem that when welding the arc beam 115, the welding equipment will apply a downward welding force to the arc beam, which will cause the welding point of the arc beam 115 to be subjected to downward pressure, thereby causing the side of the arc beam 115 to warp, and the warping of the side will cause the joint gap of the arc beam 115 to change.
[0023] Working principle: When the device is needed to weld the curved beam 115, first place the two curved beams 115 to be welded on top of the two curved plates 114 respectively. Under the action of the baffle 116, the curved beam 115 placed on top of the curved plate 114 can be prevented from sliding. After the curved beam 115 is placed, the electric telescopic rod 103 is started. The electric telescopic rod 103 drives the welding device 104 to move downward to weld the two curved beams 115. During the process of the electric telescopic rod 103 driving the welding device 104 to move downward, an extrusion force is applied to the air bag 105, thereby forcing The gas in the air bag 105 enters the telescopic tube 106 through the connecting tube 107. The gas entering the telescopic tube 106 causes the telescopic tube 106 to expand, thereby causing the telescopic tube 106 to drive the push rod 108 to move upward. During the upward movement of the push rod 108, the connecting plate 109, the strip plate 110 and the push plate 111 are driven to move upward synchronously. After the push plate 111 moves upward, it drives the push rod 112 to move upward. The push rod 112 moves upward and contacts the limit plate 120, forcing the limit plate 120 to rotate with the rotating rod 119 as the midpoint. The rotation of the limit plate 120 can fix the top of the curved beam 115. When the limit plate 120 rotates with the rotating rod 119 as the midpoint, the rotating rod 119 rotates and drives the gear 122 to rotate. The gear 122 meshes with the rack 125, so that the gear 122 rotates and drives the rack 125 to move. During the movement, the rack 125 drives the clamping plate 126 to move toward the arc beam 115. The multiple clamping plates 126 cooperate with each other and approach each other to clamp and fix the arc beam 115. Through the precise transmission of the gear 122 and the rack 125, the rotational motion of the limit plate 120 is converted into the horizontal linear motion of the clamping plate 126, forming a multi-point coordinated clamping fixed clamping; During the upward movement of the push rod 108, the push rod 108 drives the connecting bar 128 to move upward, and during the upward movement of the connecting bar 128, the arc-shaped top plate 129 is driven to move upward. When the welding equipment 104 moves downward to weld the two arc-shaped beams 115, the welding points of the two arc-shaped beams 115 are subjected to downward pressure. By supporting the welding points of the two arc-shaped beams 115 through the upward movement of the arc-shaped top plate 129, the pressure on the two arc-shaped beams 115 can be reduced, and an upward supporting force can be provided for the welding points of the two arc-shaped beams 115. The upward supporting force provided by the arc-shaped top plate 129 can directly offset the downward pressure stress of the welding equipment 104.
