Abstract
Description
Technical Field
[0001] The invention relates to a quick centering mechanism for carrying segmented modules and a manufacturing process thereof. Background Art
[0002] In processes such as shipbuilding, a mechanism is used to carry and transfer modular modules, a significant amount of daily transfer and storage work. This mechanism is lifted by a forklift and then supported by specialized tooling. Because the width of the mechanism is significantly greater than the tooling, the center of gravity of the mechanism must be aligned with the center of the shovel foot to prevent slippage. This process requires constant correction and is time-consuming. Furthermore, due to its length during fabrication, deformation must be prevented during welding, and currently no effective solution exists. The welding process utilizes heat energy, such as arc heat, physical heat, and chemical heat, to melt the base metal and weld material to form a molten weld pool. The molten pool solidifies, transforming from a liquid phase to a solid phase, resulting in crystallization. This is essentially a metallurgical process. While both welding and casting solidification involve crystallization nucleation and growth, solidification in welding differs significantly from solidification in casting, where the former is non-equilibrium solidification and the latter is equilibrium solidification. During the welding process, when a structural component is locally heated, it cannot fully stretch due to the constraints of surrounding components, generating compressive stress. As it cools, the weld shrinks, generating tensile stress, causing the weld to bend and deform. Therefore, after the welding process is completed, the weld is subject to both compressive and tensile stresses, as well as both elastic and plastic deformation. The weld shrinks and generates compressive stress, while the base metal surrounding the weld experiences tensile stress due to tension. It can be said that the generation of these stresses and strains is inevitable. Patent publication number CN104259674B: Pre-weld anti-deformation device and method for reducing angular deformation of T-joint welds. This invention relates to a welding device and method. The device comprises: a hinge shaft with two ends hinged to side brackets; two clamping rods disposed on the front and rear plates, respectively; a hydraulic cylinder with an upper end fixedly connected to the clamping rods; a hydraulic cylinder with a lower end hinged to a connecting pin; a lead screw with a lower end connected to a stepper motor; a lifting drive plate with a threaded connection to the lead screw; and a top plate support rod hinged to each side of the lifting drive plate. The upper end of one top plate support rod is hinged to the front plate, while the upper end of the other top plate support rod is hinged to the rear plate. A control box is connected to the stepper motor via a data cable, and a top plate angle sensor is disposed below the hinged anti-deformation top plate. The method comprises: 1. Setting an anti-deformation angle α; 2. Installing a card on one side of the skin; 3. Bend the skin; and 4. Double-sided laser welding of the anti-deformed skin and the stringer with continuous filler wire. This prior art is a similar technology in a similar field, but it is not suitable for the beam-type mechanism in this field that is long in length but not high in height. Summary of the Invention
[0003] The present invention aims to overcome the shortcomings of the prior art by providing a quick centering mechanism for supporting segmented modules. The centerline is marked at the center, and when used with the centerline of a corresponding tool, the centerline can be quickly aligned. When used with the corresponding tool, the mechanism is convenient and quick, reducing safety hazards.
[0004] To achieve the above objectives, the present invention proposes a rapid centering mechanism for supporting segmented modules. The mechanism comprises a channel-shaped main body, comprising a crossbeam and support legs fixedly connected to each end of the crossbeam. The legs are positioned below the crossbeam, and a marking layer is positioned in the middle of the crossbeam to indicate its center position. A centerline is marked at the center, which, when combined with the centerline of a corresponding tool, allows for rapid centerline alignment. Used in conjunction with the corresponding tool, the mechanism is convenient and quick, reducing safety hazards.
[0005] A further technical solution is a process for manufacturing a quick centering mechanism for carrying segmented modules, comprising the following manufacturing steps:
[0006] S1: The four plates of the beam are welded into a rectangular ring, and an anti-deformation welding mechanism is used to clamp them against the beam during welding;
[0007] S2: Weld the support legs to the bottom of the beam;
[0008] S3: Paint the beam to form a marking layer;
[0009] In step S1, the reinforcing baffles within the crossbeam are first welded to the left, right, and bottom crossbeam plates. Finally, the crossbeam faceplates are welded to the two rectangular ring-shaped ends. The anti-deformation mechanism effectively prevents welding deformation during long plate welding. After the left, right, and bottom crossbeam plates are welded to form (they form a channel steel shape after welding), the reinforcing baffles are welded on, which can reduce deformation to a certain extent.
[0010] A further technical solution is that the anti-deformation welding mechanism includes a base frame, two first actuating members hinged to two ends of the base frame, an actuating rod hinged to the first actuating member, an end of the actuating rod remote from the first actuating member hinged to a pressure rod, an end of the pressure rod remote from the actuating rod hinged to a piston rod of a cylinder, a cylinder body of the cylinder hinged to the base frame; the two cylinders are located between the two first actuating members;
[0011] The first actuating member is connected to a connecting rod at one end away from the actuating rod, and the connecting rod is connected to the piston rod of the second oil cylinder. After being provided with like this, the action of the oil cylinder and the second oil cylinder can achieve that the pressing rod is tightly against the plate surface of the plate to be welded.
[0012] A further technical solution is that, in step S1, a circle drawing method is used during welding;
[0013] Place the vertical plate in the crossbeam above the horizontal plate, and then place the vertical plate at the edge of the horizontal plate to form a right angle. Spot weld the outer corners of the two plates first, and then use the circular method to weld the inner corners of the two plates. Spot welding the outer corners first, then welding the inner corners. Welding on both sides can reduce deformation to a certain extent. When spot welding the outer corners, the main pressure of the anti-deformation mechanism plays a role of abutment and pressure. Because the vertical and horizontal plates are not yet connected at this time, if the pressure is inward (referring to the direction inside the right angle), it will be difficult to weld. After spot welding the outer corners, the horizontal and vertical plates are connected. When welding the inner corners, the anti-deformation mechanism presses outward to form an anti-deformation to counteract the deformation of the vertical plate in the direction of the angle after welding. (Because the outer corners are only spot welded, while the inner corners are welded along an entire side, the inner corners require more welding. During welding, the side with more welding will shrink more during cooling after welding. Therefore, the anti-deformation mechanism is activated when welding the inner corners.)
[0014] A further technical solution is to use the anti-deformation welding mechanism to successively clamp the upper end of the vertical plate, the surface away from the horizontal plate, and the surface closer to the horizontal plate, when spot welding the outer corner of the right-angled plates and welding the inner corner of the right-angled plates. The abutment area is the upper end of the vertical plate, which is sufficiently far away from the welding area to reduce the impact of the anti-deformation mechanism on the welding process.
[0015] A further technical solution is that the second oil cylinder is fixedly connected to the outer wall of the bottom frame through a connecting plate; a support column is fixedly connected to the connecting plate, and the support column is vertically arranged;
[0016] In the step S1, after the support columns are placed on the horizontal plate, the welder enters the area between the two support columns to weld the inner corners of the two right-angled plates formed by the horizontal plate and the vertical plate.
[0017] A further technical solution is that the lower end of the support column is fixedly connected to a connecting block, the connecting block is provided with a through thread, and a fastening stud is provided to match the thread;
[0018] In step S1, after placing the support columns on the horizontal plate and tightening the fastening studs until the ends of the fastening studs are firmly against the horizontal plate, the welder then enters the area between the two support columns and welds the inner corner of the right angle formed by the horizontal and vertical plates. The provision of the fastening studs ensures a secure connection between the support columns and the horizontal plate, preventing the instability of the anti-deformation mechanism due to the pressure and abutment.
[0019] A further technical solution is that, in step S1, a vertical plate is first welded to a horizontal plate, and then another vertical plate is welded to the horizontal plate to form a plate assembly in the shape of a channel steel, and then the reinforcing partition is welded to the left, right, and bottom plates of the crossbeam;
[0020] The reinforced partition is perpendicular to the left, right and bottom plates of the beam.
[0021] The advantages and benefits of this invention include: The anti-deformation mechanism effectively prevents welding deformation during long plate welding. The centerline is marked at the center of the device, enabling rapid alignment of the centerline when used with the corresponding tooling. Used in conjunction with the corresponding tooling, the device is convenient and efficient, reducing safety hazards.
[0022] After the left, right and lower plates of the beam are welded into shape (the left, right and lower plates are in the shape of channel steel after welding), the reinforcing partitions are welded on to reduce deformation to a certain extent.
[0023] First spot weld the outer corners, then weld the inner corners. Welding on both sides can reduce deformation to a certain extent. When spot welding the outer corners, the main pressure of the anti-deformation mechanism plays a role of abutment and pressure, because the vertical plate and the horizontal plate are not connected at this time. If they are pressed inward (referring to the direction inside the right angle), it will be difficult to weld. After spot welding the outer corners, the horizontal plate and the vertical plate are connected. When welding the inner corners, the anti-deformation mechanism presses outward to form an anti-deformation to resist the deformation of the vertical plate in the direction inside the angle after welding (because the outer corners are only spot welded, and the inner corners are welded on an entire side, so the inner corners have a large amount of welding. When welding, whichever side has a large amount of welding, then the shrinkage of this side will be relatively large during cooling after welding. Therefore, the anti-deformation mechanism works when welding the inner corners).
[0024] The abutting part is the upper end of the vertical plate, which is sufficiently far away from the welding area, thereby reducing the influence of the anti-deformation mechanism on welding.
[0025] The fastening studs are provided to ensure that the support column is securely connected to the horizontal plate, thereby avoiding the problem of instability caused by the pressing and abutting of the anti-deformation mechanism. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION
[0033] The following embodiments are further described in conjunction with the accompanying drawings and examples. The following embodiments are only used to more clearly illustrate the technical solutions of the present invention and are not intended to limit the scope of protection of the present invention.
[0034] like Figures 1 to 6 As shown, the present invention is a quick centering mechanism for carrying segmented modules, including a mechanism body in the shape of a channel steel, the mechanism body including a beam 1 and support legs 2 fixedly connected to both ends of the beam 1, the support legs 2 are located below the beam 1, and an identification layer 3 for identifying the center position of the beam 1 is provided in the middle position of the beam 1.
[0035] The manufacturing process of a quick centering mechanism for carrying segmented modules includes the following steps:
[0036] S1: Weld the four plates of the beam 1 into a rectangular ring, and use an anti-deformation welding mechanism to clamp them against the beam 1 during welding;
[0037] S2: Weld support leg 2 to the bottom of beam 1;
[0038] S3: applying paint on the beam 1 to form a marking layer 3;
[0039] In the step S1, the reinforcing partition 4 inside the beam 1 is first welded to the left, right and bottom plates of the beam 1, and finally the panel 5 of the beam 1 is welded to the two ends of the rectangular ring.
[0040] The anti-deformation welding mechanism includes a base frame 6, two first actuators 7 hinged to the two ends of the base frame 6, an actuator rod 8 hinged to the first actuator 7, an end of the actuator rod 8 away from the first actuator 7 is hinged to a pressure rod 9, and the end of the pressure rod 9 away from the actuator rod 8 is hinged to the piston rod 11 of the oil cylinder 10, and the cylinder body of the oil cylinder 10 is hinged to the base frame 6; the two oil cylinders 10 are located between the two first actuators 7; the end of the first actuator 7 away from the actuator rod 8 is connected to the connecting rod 12, and the connecting rod 12 is connected to the piston rod of the second oil cylinder 13. In step S1, the circular method is used for welding; the vertical plate 14 in the crossbeam 1 is placed above the horizontal plate 15, and the vertical plate 14 is placed at the edge of the horizontal plate 15 to form a right angle. Spot welding is first performed at the outer corners of the two right-angled plates, and then the circular method is used for welding at the inner corners of the two right-angled plates. During spot welding at the outer corner of the right-angled plates and welding at the inner corner of the right-angled plates, the anti-deformation welding mechanism is used to successively clamp the upper end of the vertical plate 14, the surface away from the horizontal plate 15, and the surface close to the horizontal plate 15. The second oil cylinder 13 is fixedly connected to the outer wall of the bottom frame 6 via a connecting plate 16; a support column 17 is fixedly connected to the connecting plate 16, and the support column 17 is arranged vertically. In step S1, after the support column 17 is placed on the horizontal plate 15, the welder enters the area between the two support columns 17 to weld the inner corner of the right-angled plates formed by the horizontal plate 15 and the vertical plate 14. The lower end of the support column 17 is fixedly connected to a connecting block 18, which is provided with a through-thread and a fastening stud 19 adapted to the thread. In step S1, after the support column 17 is placed on the horizontal plate 15 and the fastening stud 19 is tightened so that the end of the fastening stud 19 is tightly against the horizontal plate 15, the welder enters the area between the two support columns 17 and welds the inner corner of the right angle formed by the horizontal plate 15 and the vertical plate 14. In step S1, one vertical plate 14 is first welded to the horizontal plate 15, and then the other vertical plate 14 is welded to the horizontal plate 15 to form a plate assembly in the shape of a channel steel. Then, the reinforcing partition 4 is welded to the left, right, and bottom plates of the crossbeam 1. The reinforcing partition 4 is perpendicular to the left, right, and bottom plates of the crossbeam 1.
[0041] Here’s how it works:
[0042] The center line is marked in the center, and when combined with the center line of the corresponding tooling, the center line can be quickly aligned. When used in conjunction with the corresponding tooling, it is convenient and fast, reducing safety hazards.
[0043] There is one or more anti-deformation welding mechanisms. If one is set, after each welding of the part of the weld within the length direction dimension of the anti-deformation welding mechanism, the anti-deformation welding mechanism is released, the position is adjusted, and then the vertical plate is clamped against the next section to be welded, and the welder continues welding.
[0044] If multiple anti-deformation welding mechanisms are installed, after the welder completes the portion of the weld within the length of the anti-deformation welding mechanism in the current position, the welder exits the anti-deformation welding mechanism and enters the next anti-deformation welding mechanism to weld the inner corners of two plates at a right angle. For the unwelded areas at the ends of the anti-deformation welding mechanism, the positions of the anti-deformation welding mechanisms are finally adjusted to weld the areas previously blocked by the anti-deformation welding mechanisms.
[0045] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the technical principles of the present invention. These improvements and modifications should also be regarded as within the scope of protection of the present invention.
