Description

Technical Field

[0001] This invention relates to the field of automated welding technology, and more specifically, to an auxiliary welding device for ship lashing bowls. Background Technology

[0002] In the deck sections of pure car and truck carriers, the welding of cloverleaf lashing bowls is a key process to ensure the stability of the vehicle lashing system. Before welding, the cloverleaf lashing bowls need to be positioned and marked on the ship's deck. According to the deck section drawings, the installation position of the cloverleaf lashing bowls is accurately located using a total station or laser projector to ensure that it meets the grid layout requirements of the lashing system.

[0003] While existing lashing bowl positioning fixtures can improve the efficiency of lashing bowl positioning and installation, they primarily focus on the positioning and installation efficiency of the lashing bowls and fail to address the problem of unevenness on the front of the deck during welding.

[0004] Furthermore, while the existing lashing bowl installation process effectively prevents damage to the internal coating of the lashing bowl during welding, it lacks technical measures to prevent deck deformation during welding, hindering further improvements in welding efficiency and quality. Welding the lashing bowls often requires flipping the deck over, with two workers operating from both sides to avoid unevenness on the deck surface. This not only increases operational complexity but also reduces welding efficiency. Summary of the Invention

[0005] To address the issues of insufficient deck deformation control and limited room for improvement in welding efficiency and quality in existing technologies, a new auxiliary welding device for ship lashing bowls is needed. This device is designed to fix the lashing bowls, ensure their perpendicularity to the deck, prevent displacement caused by welding thermal deformation, improve the welding efficiency of the lashing bowls, and prevent unevenness on the front of the deck. It also improves the welding efficiency and quality of the lashing bowls while ensuring the flatness of the deck.

[0006] This application provides an auxiliary welding device for ship lashing bowls, comprising: a gripping component including a palm rest and gripping fingers, wherein there are multiple gripping fingers evenly arranged around the palm rest, one end of each gripping finger is connected to the palm rest, the other end of each gripping finger is at the same horizontal plane, and each gripping finger is bent at a preset arc to cooperate with the lashing bowl; a limiting component, provided at least on some of the gripping fingers, capable of adjusting its own position in the height direction of the gripping component; and an adsorption component, disposed on the palm rest.

[0007] In some alternative embodiments, the ends of each grasping finger connected to the palm rest are on the same horizontal plane, and the center point of the palm rest is located on the horizontal plane.

[0008] In some optional embodiments, the grasping finger includes an arc segment, a first linear segment, and a second linear segment, the first linear segment and the second linear segment being tangent to the arc segment, the first linear segment being connected to the palm rest, and the end of the second linear segment away from the palm rest being on the same horizontal plane.

[0009] In some alternative embodiments, the first linear segment, the arc segment, and the second linear segment are integrally formed.

[0010] In some optional embodiments, the included angle between the centers of the arc segment and the center of the circle is 30° to 120°.

[0011] In some alternative embodiments, the limiting member is disposed on the second linear segment, and the limiting member adjusts its position in the extension direction of the second linear segment.

[0012] In some optional embodiments, the limiting component includes a limiting nut and a screw, the limiting nut being disposed on the second linear segment, and the screw being screwed to the limiting nut.

[0013] In some optional embodiments, the palm rest further includes a plurality of support plates, which are evenly arranged around the central hole of the palm rest. The support plates are opposite to the extension direction of the grasping fingers. The plurality of support plates and the palm rest enclose a limiting groove, and the adsorption component is disposed in the limiting groove.

[0014] In some alternative embodiments, each of the support plates is L-shaped.

[0015] In some alternative embodiments, the adsorption component includes a housing and a magnetic adsorption element, the housing being connected to a plurality of the support plates, the magnetic adsorption element being disposed within the housing, and the housing having an opening facing the grasping finger.

[0016] Compared with the prior art, the present invention has the following technical advantages:

[0017] This application provides an auxiliary welding device for ship lashing bowls, comprising: a gripping component, a limiting component, and an adsorption component. The gripping component includes a palm support and multiple gripping fingers evenly distributed around the palm support. One end of each gripping finger is connected to the palm support, and the other end of each gripping finger is on the same horizontal plane. Each gripping finger is bent at a preset arc to mate with the lashing bowl. The preset arc ensures a tight fit with the curved surface of the lashing bowl, ensuring uniform force during welding and avoiding uneven deformation of the deck surface caused by welding stress concentration. This also avoids the cumbersome process of deck flipping and double-sided operation required in traditional processes. The limiting component is provided at least on some of the gripping fingers to specifically enhance the limiting ability of key stress points, preventing excessive constraint that prevents welding stress from being released. The limiting component can adjust its position in the height direction of the gripping component. The limiting component can flexibly adjust its position according to the thickness of the deck section or the installation height of the lashing bowl to ensure that the relative position of the lashing bowl and the deck meets the requirements during welding. The adsorption component is mounted on the palm rest, fixing the entire device to the deck, replacing manual pressing or additional clamps, reducing deviations caused by vibration or displacement during welding, and freeing up the operator's hands, thus improving individual work efficiency. The ship lashing bowl auxiliary welding device, through uniform force and rigid support, avoids deck unevenness caused by welding thermal stress; welding can be completed by a single worker operating on one side of the deck, reducing personnel and time consumption.

[0027] To better understand the above-mentioned objectives, features, and advantages of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0028] Many specific details are set forth in the following description in order to provide a full understanding of the invention. However, the invention may also be practiced in other ways different from those described herein, and therefore the scope of protection of the invention is not limited to the specific embodiments disclosed below.

[0029] In the deck sections of pure car and truck carriers, the welding of cloverleaf lashing bowls is a key process to ensure the stability of the vehicle lashing system. Before welding, the cloverleaf lashing bowls need to be positioned and marked on the ship's deck. According to the deck section drawings, the installation position of the cloverleaf lashing bowls is accurately located using a total station or laser projector to ensure that it meets the grid layout requirements of the lashing system.

[0030] While existing lashing bowl positioning fixtures can improve the efficiency of lashing bowl positioning and installation, they primarily focus on the positioning and installation efficiency of the lashing bowls and fail to address the problem of unevenness on the front of the deck during welding.

[0031] Furthermore, while the existing lashing bowl installation process effectively prevents damage to the internal coating of the lashing bowl during welding, it lacks technical measures to prevent deck deformation during welding, hindering further improvements in welding efficiency and quality. Welding the lashing bowls often requires flipping the deck over, with two workers operating from both sides to avoid unevenness on the deck surface. This not only increases operational complexity but also reduces welding efficiency.

[0032] To address the issues of insufficient deck deformation control and limited room for improvement in welding efficiency and quality in existing technologies, a new auxiliary welding device for ship lashing bowls is needed. This device is designed to fix the lashing bowls, ensure their perpendicularity to the deck, prevent displacement caused by welding thermal deformation, improve the welding efficiency of the lashing bowls, and prevent unevenness on the front of the deck. It also improves the welding efficiency and quality of the lashing bowls while ensuring the flatness of the deck.

[0033] The following is in conjunction with the accompanying drawings in the instruction manual. Figures 1-6 A detailed description is provided of the auxiliary welding device for ship lashing bowls.

[0034] This application provides an auxiliary welding device for ship lashing bowls. The auxiliary welding device for ship lashing bowls includes: a gripping component 1, including a palm support 11 and gripping fingers 12. There are multiple gripping fingers 12, which are evenly arranged around the palm support 11. One end of each gripping finger 12 is connected to the palm support 11, and the other end of each gripping finger 12 is on the same horizontal plane. Each gripping finger 12 is bent at a preset arc to cooperate with the lashing bowl; a limiting component 2, which is provided at least on some of the gripping fingers 12, and can adjust its own position in the height direction of the gripping component 1; and an adsorption component 3, which is provided on the palm support 11.

[0035] Specifically, the auxiliary welding device for ship lashing bowls includes: a gripping component 1, a limiting component 2, and an adsorption component 3. The gripping component 1 includes a palm support 11 and gripping fingers 12. There are multiple gripping fingers 12, which are evenly arranged around the palm support 11. One end of each gripping finger 12 is connected to the palm support 11, and the other end of each gripping finger 12 is on the same horizontal plane. Each gripping finger 12 is bent at a preset arc to cooperate with the lashing bowl. By closely fitting the curved surface of the lashing bowl with the preset arc, it ensures uniform force during welding, avoids the problem of uneven deformation on the front of the deck due to welding stress concentration, and avoids the cumbersome process of deck flipping and double-sided operation required in traditional processes. Limiting components 2 are installed at least on some of the gripping fingers 12 to specifically enhance the limiting ability of key stress points, avoiding excessive constraint that prevents the release of welding stress. Limiting components 2 can adjust their position in the height direction of the gripping components 1. The position of limiting components 2 can be flexibly adjusted according to the thickness of the deck sections or the installation height of the lashing bowls, ensuring that the relative position of the lashing bowls and the deck meets requirements during welding. Adsorption components 3 are installed on the palm support 11, fixing the entire device to the deck, replacing manual pressing or additional clamps, reducing deviations caused by vibration or displacement during welding, and freeing up the operator's hands, improving individual work efficiency. The ship lashing bowl auxiliary welding device, through uniform force and rigid support, avoids deck unevenness caused by welding thermal stress; welding can be completed by a single worker operating on one side of the deck, reducing personnel and time consumption.

[0036] In some alternative embodiments, the ends of each grasping finger 12 connected to the palm rest 11 are on the same horizontal plane, and the center point of the palm rest 11 is located on the horizontal plane.

[0037] Specifically, the connecting ends of the gripping fingers 12 and the palm support 11 are on the same horizontal plane, and the center point of the palm support 11 is located on this horizontal plane. This makes the connecting ends of the gripping fingers 12 coplanar and symmetrical about the center of the palm support 11. This allows the pressure applied to the lashing bowl during welding to be evenly transmitted to the deck through the gripping fingers 12, eliminating local stress concentration and fundamentally preventing unevenness of the deck after welding. The design that the ends of each gripping finger 12 connected to the palm support 11 are on the same horizontal plane provides a stable installation reference for the gripping component 1, ensuring that its axis is perpendicular to the deck every time the lashing bowl is gripped. This avoids positioning deviations caused by tooling errors and allows the palm support 11 and gripping fingers 12 to form a stable planar frame structure, resisting thermal deformation during welding and preventing tooling deformation from affecting welding quality. By keeping the ends of the gripping fingers 12 coplanar, various sizes of lashing bowls can be adapted simply by adjusting the curvature or length of the gripping finger ends.

[0038] In some alternative embodiments, the grasping finger 12 includes an arc segment, a first linear segment and a second linear segment, the first linear segment and the second linear segment being tangent to the arc segment, the first linear segment being connected to the palm rest 11, and the end of the second linear segment away from the palm rest 11 being on the same horizontal plane.

[0039] Specifically, the gripping finger 12 consists of an arc-shaped segment, a first linear segment, and a second linear segment, with the two linear segments tangent to the arc-shaped segment. This eliminates stress concentration points in traditional bending structures, allowing welding pressure to be transferred from the palm support 11 to the binding bowl through a smooth force flow path, significantly reducing the risk of root fracture of the gripping finger 12. The first linear segment provides rigid support to resist axial pressure during welding. The second linear segment ensures the horizontal positioning of the binding bowl through its coplanar ends, avoiding uneven welding caused by tilting. The curvature of the gripping finger 12 matches the outer contour of the four-leaf clover binding bowl, increasing the contact area and preventing relative sliding between the gripping finger 12 and the bowl body during welding. The ends of the second linear segments of all gripping fingers 12 are on the same horizontal plane, forcing the welding surface of the binding bowl to be parallel to the deck, eliminating angular deviations caused by tooling errors. Under welding thermal stress, the arc-shaped segment can undergo slight elastic deformation to absorb local stress, preventing stress from being directly transmitted to the deck.

[0040] In some alternative embodiments, the first linear segment, the arc segment, and the second linear segment are integrally formed.

[0041] In some optional embodiments, the included angle between the centers of the arc segment and the center of the circle is 30° to 120°.

[0042] Specifically, the minimum boundary of the included angle between the centers of the arc segment and the circle is 30°. The arc segment tightly wraps around the blades on one side of the bowl body, providing high rigidity clamping force and preventing micro-displacement caused by welding vibration. The maximum boundary of the included angle between the centers of the arc segment and the circle is 120°, forming multi-point pressure-equalizing contact, dispersing welding stress, and enhancing the ability to resist eccentric loads.

[0043] In some alternative embodiments, the limiting member 2 is disposed on the second linear segment, and the limiting member 2 adjusts its position in the extension direction of the second linear segment.

[0044] Specifically, the limiting component 2 adjusts its position in the extension direction of the second linear segment, which can adjust the constraint position in real time for decks of different thicknesses, thereby improving the fixing force on the lashing bowl. In addition, during the welding heat shrinkage stage, the limiting component 2 provides reverse mechanical resistance, controlling the deck deformation to within 0.1 mm / m.

[0045] In some optional embodiments, the limiting component 2 includes a limiting nut 21 and a screw 22, the limiting nut 21 being disposed on the second linear segment, and the screw 22 being screwed to the limiting nut 21.

[0046] Specifically, the screw 22 is screwed to the limiting nut 21, thereby adjusting the length of the screw 22 in the second linear segment direction.

[0047] In some optional embodiments, the palm rest 11 further includes a plurality of support plates 112, which are evenly arranged around the central hole of the palm rest 11. The support plates 112 extend in the opposite direction to the grasping fingers 12. The plurality of support plates 112 and the palm rest 11 enclose a limiting groove, and the adsorption component 3 is disposed in the limiting groove.

[0048] In some alternative embodiments, each support plate 112 is L-shaped.

[0049] In some alternative embodiments, the adsorption component 3 includes a housing and a magnetic adsorption element. The housing is connected to a plurality of support plates 112, and the magnetic adsorption element is disposed inside the housing. The housing has an opening facing the grasping finger 12.

[0050] Specifically, the magnetic adsorption element is an electromagnetic chuck or a vacuum chuck. The magnetic adsorption element fixes the binding bowl to the deck, replacing manual pressing or additional clamps, reducing deviations caused by vibration or displacement during welding, while freeing up the operator's hands and improving individual work efficiency.
