Description

Technical Field

[0001] This invention relates to the field of welding technology, specifically to an auxiliary device for welding thick plates. Background Technology

[0002] Welding is a manufacturing process that joins metals or other thermoplastic materials such as plastics by heating, high temperature, or high pressure. In marine engineering, the construction of large pressure vessels, and large container ships, thick steel plates are increasingly used for welding due to the need for thicker plates to construct outer layers and load-bearing components.

[0003] When welding thick plates, double-sided welding is required to increase the strength of the weld. Two thick plates are placed flat on the welding platform. After welding one side of the thick plates, they need to be flipped. However, the joint between the two thick plates is prone to breakage due to stress and other factors. In addition, the two thick plates are heavy and difficult to flip. If the two thick plates need to be welded at a specific angle, the welding operator needs to flip one of the thick plates upward and tilt it at a specific angle. The operation is relatively troublesome and the flipping angle is not easy to control. Summary of the Invention

[0004] The purpose of this invention is to provide a thick plate welding auxiliary device to solve the problems mentioned in the background art.

The two belt conveyor sections are used to transport the thick plate to be welded to the state adjustment mechanism. The state adjustment mechanism includes a side steering support assembly, an upper steering support assembly, a side fixing plate, a side steering motor, and an angle adjustment drive assembly. Two side fixing plates are respectively rotatably connected to both ends of the side steering support assembly. Each side fixing plate is connected to a corresponding auxiliary support section and is equipped with a side steering motor that drives the side steering support assembly to rotate. The rotation center line of the side steering support assembly is aligned with the area to be welded by the belt conveyor section. The thick plates move in parallel directions on the conveyor belt; there are two upper steering support assemblies, which are symmetrically arranged at both ends of the side steering support assembly.

The two adjusting slides are mounted on the side steering support assembly and slide in cooperation with the guide rod. The guide rod is mounted on the side steering support assembly along the left-right rotating adjusting screw.

Detailed Implementation

[0025] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. In the drawings or description, similar or identical parts are referred to by the same reference numerals, and in practical applications, the shape, thickness, or height of each component may be enlarged or reduced. The embodiments listed in this invention are merely illustrative and not intended to limit the scope of the invention. Any obvious modifications or changes made to this invention do not depart from the spirit and scope of the invention.

[0026] In one embodiment, such as Figure 1 and Figure 2 As shown, a thick plate welding auxiliary device includes an auxiliary support section 100, a belt conveyor section 200, and a state adjustment mechanism 300. Two belt conveyor sections 200 are respectively located on both sides of the state adjustment mechanism 300, which is mounted on the auxiliary support section 100. The two belt conveyor sections 200 are used to convey the thick plate to be welded to the state adjustment mechanism 300. The state adjustment mechanism 300 includes a side steering support assembly 400, an upper steering support assembly 500, a side fixing plate 600, a side steering motor 700, and an angle adjustment drive assembly 900. Two side fixing plates 600 are respectively rotatably connected to both ends of the side steering support assembly 400. Each side fixing plate 600 is connected to a corresponding auxiliary support section 100, and a side steering motor 700 is provided on the side fixing plate 600 to drive the side steering support assembly 400 to rotate. The rotation center of the side steering support assembly 400 is... The direction of movement of the thick plate to be welded on the conveyor belt 200 is parallel to the direction of movement of the conveyor belt 200; there are two upper steering support assemblies 500, and the two upper steering support assemblies 500 are symmetrically rotatably disposed at both ends of the side steering support assembly 400. The rotation center line of the upper steering support assembly 500 is parallel to the width direction of the conveyor belt 200, and the thick plate to be welded is conveyed to the corresponding upper steering support assembly 500 by the conveyor belt 200; the angle adjustment drive assembly 900 is disposed on the side steering support assembly 400 and is connected to both upper steering support assemblies 500. The angle adjustment drive assembly 900 can drive the two upper steering support assemblies 500 to rotate synchronously and in opposite directions. A side clamping part 550 is provided on the same side of both upper steering support assemblies 500. When the side steering support assembly 400 is tilted, the side clamping part 550 can lift the side of the thick plate to be welded and press the thick plate.

[0027] In this embodiment of the invention, two thick plates to be welded are respectively placed on two conveyor belts 200 with their welding edges facing each other. The two conveyor belts 200 work synchronously and convey the two thick plates to two upper steering support assemblies 500. When the front ends of the thick plates are on the corresponding upper steering support assemblies 500 and the front ends of the two thick plates are in contact, the conveyor belts 200 stop working. If the two thick plates are to be welded horizontally, the welding operator welds the contacting front ends of the two thick plates together from the top. If the two thick plates need to be welded at an angle, the angle adjustment drive assembly 900 drives the two upper steering support assemblies 500 to rotate synchronously and in opposite directions, with the opposite ends of the two upper steering support assemblies 500 rotating downwards. As a result, the two thick plates rotate with the upper steering support assemblies 500 and form an angle. At this time, the welding operator welds the contacting front ends of the two thick plates together from the top surface. After the upper surface of the thick plates is welded, the side steering motor 700 drives the side steering support assembly 400 to rotate and the side steering support assembly 400 is to be welded together. The steering support assembly 400 rotates downward toward the side where the side clamping part 550 is located, causing the two welded thick plates to slide laterally along the upper steering support assembly 500 until the upper steering support assembly 500 and the thick plates are in a vertical position. The sides of the thick plates are supported by the side clamping part 550, and the side clamping part 550 presses the thick plates to prevent them from detaching from the upper steering support assembly 500. Then, the welding operator can weld the two thick plates from the unwelded side. Since the thick plates are in a vertical position, welding is easier. The welding process is carried out on both sides to ensure the strength of the weld. After welding, the side steering motor 700 drives the side steering support assembly 400 to rotate in the opposite direction, causing the side clamping part 550 to tilt upwards. As a result, the welded thick plate automatically slides out from the side of the upper steering support assembly 500 away from the side clamping part 550, allowing for automatic unloading. After unloading, the angle adjustment drive assembly 900 and the side steering motor 700 drive the side steering support assembly 400 and the upper steering support assembly 500 back to their initial horizontal state.

[0028] In one embodiment, such as Figures 1-5As shown, the upper steering support assembly 500 includes an upper support frame 510 and an upper steering shaft 530. The upper steering shaft 530 is mounted on the side steering support assembly 400 at both ends via rotating seats, and is connected to an angle adjustment drive assembly 900, which can drive the upper steering shaft 530 to rotate. The upper support frame 510 is fixed to the upper steering shaft 530 on both sides, and multiple support rollers 520 arranged side-by-side are provided inside the upper support frame 510. The end of the plate 20 is rotatably connected to the inner wall of the upper support frame 510, and the side clamping part 550 is provided on one side of the upper support frame 510. In this embodiment of the invention, the front end of the thick plate is on the upper support frame 510 and is rolled up by the support roller 520. When the angle adjustment drive assembly 900 drives the upper steering shaft 530 to rotate, the upper steering shaft 530 drives the upper support frame 510 to tilt. When the upper support frame 510 tilts, the thick plate moves to the tilted and downward end of the upper support frame 510 under its own gravity.

[0029] In one embodiment, such as Figures 1-5 As shown, when the upper steering support assembly 500 is in a horizontal state, the arc apex of the support roller 520 is on the same horizontal plane as the upper surface of the belt conveyor 200, so as to ensure that the thick plate moves from the belt conveyor 200 to the upper steering support assembly 500 without obstruction.

[0030] In one embodiment, such as Figures 1-5 As shown, a lower steering gear 540 is provided on the upper steering shaft 530, and at least one adjusting motor 950 is provided on the side steering support assembly 400. The angle adjustment drive assembly 900 includes a left-right rotating adjusting screw 910, a guide rod 940, and two adjusting slides 920. The left-right rotating adjusting screw 910 is rotatably mounted on the side steering support assembly 400, and its axis is parallel to the length direction of the side steering support assembly 400. One end of the left-right rotating adjusting screw 910 is connected to the output end of the adjusting motor 950. The two adjusting slides 920 are provided on the side steering support assembly 400, and the adjusting slides 920 are slidably engaged with the guide rod 940. A left-right rotating adjusting screw 910 is mounted on the side steering support assembly 400. The two ends of the left-right rotating adjusting screw 910 spirally pass through the adjusting slide 920, and each adjusting slide 920 is provided with an upper rack 930. The two upper racks 930 mesh with the two lower steering gears 540 respectively. In this embodiment of the invention, the adjusting motor 950 drives the left-right rotating adjusting screw 910 to rotate, and the rotating left-right rotating adjusting screw 910 drives the two adjusting slides 920 to move towards or away from each other. The two upper racks 930 move with the corresponding adjusting slides 920 respectively. The upper racks 930 rotate by meshing with the corresponding lower steering gears 540.

[0031] In one embodiment, such as Figures 1-5 As shown, the side clamping part 550 includes a clamping shaft 551, a lower support plate 552, and an upper clamping frame 553. Both ends of the clamping shaft 551 are rotatably connected to the side of the upper support frame 510 via supports. The lower support plate 552 is located between the clamping shaft 551 and the upper support frame 510, with its end away from the upper support frame 510 extending to the upper side of the support roller 520. The upper clamping frame 553 is located on the side wall of the clamping shaft 551 away from the upper support frame 510, with its end away from the clamping shaft 551... A clamping roller 554 is provided and rotatably connected thereto. In this embodiment of the invention, when the upper support frame 510 tilts to one side of the side clamping part 550, the thick plate slides to one side of the side clamping part 550, and the lower support plate 552 contacts the side of the thick plate. Due to the gravity of the thick plate, the thick plate pushes the lower support plate 552 to rotate, and the lower support plate 552 drives the clamping shaft 551 and the upper clamping frame 553 to rotate. As a result, the clamping roller 554 rotates towards the surface of the thick plate and the clamping roller 554 presses against the surface of the thick plate, preventing the thick plate from detaching from the upper support frame 510 due to tilting.

[0032] In one embodiment, such as Figure 2 and Figure 3 As shown, the side fixing plate 600 is slidably engaged with the auxiliary support portion 100. A lower limit block 110 is provided on the auxiliary support portion 100 located below the side fixing plate 600. The side steering support assembly 400 includes a lower steering bracket 410, a lower steering shaft 420, and a lower inclined lifting portion 430. Both ends of the lower steering shaft 420 are rotatably connected to the two side fixing plates 600, and one end of the lower steering shaft 420 is connected to the output end of the side steering motor 700. The lower steering bracket 410 is mounted on the lower steering shaft 420 and supports the upper steering support assembly 500. There are two lower inclined lifting portions 430, each located at one end of the lower steering shaft 420. The lower end of 0 rolls into contact with the bottom of the auxiliary support portion 100; in this embodiment of the invention, the side steering motor 700 drives the lower steering shaft 420 to rotate, and the lower steering shaft 420 drives the lower steering bracket 410 and the lower inclined lifting portion 430 to rotate; when the lower inclined lifting portion 430 rotates from the inclined state to the vertical state, the lower inclined lifting portion 430 can push the lower steering bracket 410 and the lower steering shaft 420 to move upward, thereby moving the upper steering support assembly 500 and the thick plate upward, thereby avoiding interference with the belt conveyor portion 200 when the thick plate rotates to the vertical state; when the lower inclined lifting portion 430 rotates from the vertical state to the inclined state, the lower steering shaft 420 and the lower steering bracket 410 move downward and the upper steering support assembly 500 moves downward to the initial position.

[0033] In one embodiment, such as Figure 2 and Figure 3As shown, the lower inclined lifting part 430 includes a connecting sleeve 431 and two inclined support arms 432. The connecting sleeve 431 is fixedly sleeved on the lower steering shaft 420, and the two inclined support arms 432 are respectively fixed on the two side walls of the connecting sleeve 431. The end of the inclined support arm 432 away from the connecting sleeve 431 is provided with a support roller 433, and the support roller 433 rolls in contact with the bottom of the auxiliary support part 100. In the embodiment of the present invention, when the lower steering bracket 410 is in a horizontal state, both support rollers 433 roll in contact with the bottom of the auxiliary support part 100. When the lower steering shaft 420 rotates under the drive of the side steering motor 700, one of the support rollers 433 rolls relative to the bottom of the auxiliary support part 100, and then one of the inclined support arms 432 rotates from the inclined state to the vertical state, thereby lifting the lower steering shaft 420 and the lower steering bracket 410 upward, and the lower steering bracket 410 and the upper steering support assembly 500 move upward.

[0034] In one embodiment, such as Figure 2 and Figure 3 As shown, a positioning component 800 is also provided in the middle of the lower steering bracket 410. The positioning component 800 includes a positioning slide 810 and a positioning baffle 820. The positioning slide 810 is fixed in the middle of the lower steering bracket 410 and is arranged along the width direction of the lower steering bracket 410. The positioning baffle 820 is slidably disposed on the positioning slide 810 and can be pulled out from both ends of the positioning slide 810. A pull rod 830 is provided at both ends of the positioning baffle 820. In this embodiment of the invention, when the two upper steering support components 500 are tilted toward each other, the thick plate slides along the upper steering support component 500 toward the middle position. After the welding edges of the two thick plates come into contact with the side of the positioning baffle 820, the pull rod 830 is held and the positioning baffle 820 is pulled out from the positioning slide rail 810, so that the welding edges of the two thick plates can be joined together at the middle position of the lower steering bracket 410. Moreover, when the positioning baffle 820 is pulled out, the welding edges of the thick plates can be ground to facilitate subsequent welding operations.

[0035] The above embodiment provides a thick plate welding auxiliary device, wherein two conveyor belts 200 operate synchronously and convey two thick plates to two upper steering support assemblies 500; when the front ends of the thick plates are on the corresponding upper steering support assemblies 500 and the front ends of the two thick plates are in contact, the conveyor belts 200 stop operating; if the two thick plates are to be welded face-to-face, the welding operator welds the contact portions of the front ends of the two thick plates together from the top; if the two thick plates need to be welded at an angle, the angle adjustment drive assembly 900 drives the two upper steering support assemblies 500 to rotate synchronously and in opposite directions, with the opposite ends of the two upper steering support assemblies 500 rotating downwards, and thus the two thick plates rotate with the upper steering support assemblies 500 and form an angle, at which point the welding operator welds the contact portions of the front ends of the two thick plates together from the top surface; after the upper surface of the thick plates is welded, the side steering motor 700 drives the side steering support assembly 400 to rotate and the side steering support assembly 400 faces the side clamp. The side where the holding part 550 is located rotates downward, and the two welded thick plates slide laterally along the upper steering support assembly 500 until the upper steering support assembly 500 and the thick plates are in a vertical state. The sides of the thick plates are lifted by the side clamping part 550 and the side clamping part 550 presses the thick plates to prevent them from detaching from the upper steering support assembly 500. Then, the welding operator can weld the two thick plates from the unwelded side of the thick plates. Since the thick plates are in a vertical state, the welding operation is convenient and double-sided welding is possible, ensuring the strength of the weld. After the welding is completed, the side steering motor 700 drives the side steering support assembly 400 to rotate in the opposite direction, causing the side where the side clamping part 550 is located to tilt upward. Then, the welded thick plates automatically slide out from the side of the upper steering support assembly 500 away from the side clamping part 550, which can automatically unload the material. After unloading is completed, the angle adjustment drive assembly 900 and the side steering motor 700 drive the side steering support assembly 400 and the upper steering support assembly 500 back to the initial horizontal state.

Any variations or substitutions that can be easily conceived by those skilled in the art within the scope of the technology disclosed in this disclosure should be included within the scope of protection of this disclosure.
