Description

Technical Field

[0001] The present invention specifically relates to the technical field of welding positioning of a draft tube, and more specifically, it is a welding positioning system for carbon dioxide gas shielded welding of a draft tube. Background Art

[0002] The draft tube for a ship propeller is an important component in a ship propulsion system; by guiding the water flow through the draft tube to the propeller, the draft tube can concentrate and rectify the water flow, enabling the water flow to impact the propeller blades at a more appropriate angle and speed. The propeller rotates to do work and push the water flow backward, and the draft tube helps to increase the axial velocity of the water flow, thereby improving the propulsion efficiency of the propeller. At the same time, the draft tube can also reduce the rotational energy loss of the propeller wake and convert more energy into the propulsion force of the ship.

[0003] In the processing of existing draft tube welding devices, the welding of the draft tube is achieved through a fixed positioning device. In this way, during welding, the welding device can only weld a draft tube of a certain length, and one positioning device can only achieve the effect of welding a draft tube of one size, resulting in low working efficiency of the positioning device. Moreover, during the welding process of the existing welding device, the weld on the draft tube may shift, which may cause unqualified welding quality, and the current welding positioning device cannot be effectively adjusted according to the size of the pipeline. Summary of the Invention

[0004] The purpose of the present invention is to provide a welding positioning system for carbon dioxide gas shielded welding of a draft tube. In this device, the steel plate is shaped into a circular shape by a shaping machine. After the shaping is completed, the steel plate is transmitted through the shaping machine and reaches between two positioning guide wheels. The arc surface of the positioning guide wheels contacts the outer wall of the draft tube to achieve the transmission of the draft tube. During the transmission of the draft tube, the unclosed notch on the draft tube passes through the hanging plate, effectively ensuring that the notch is always located at the top position of the draft tube during the transmission process. The electric push cylinder drives the bottom frame to move backward, and at the same time, the top frame is hinged with the telescopic rod to achieve upward adjustment, thereby making the two symmetric positioning guide wheels tend to be parallel, effectively adjusting the distance between the two positioning guide wheels, and facilitating the welding treatment of draft tubes of different sizes, so as to solve the problems in the above background art.

Detailed implementation manners

[0032] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments.

[0033] Please refer to Figures 1-9, in the embodiment of the present invention, a welding positioning system for carbon dioxide gas shielded welding of a diversion tube includes a frame body 1; a positioning component 4 is cooperatively installed on the workbench of the frame body 1; the positioning component 4 includes multiple groups of positioning guide wheels 41 arranged symmetrically, and the positioning guide wheels 41 are inclined; the axial directions of two positioning guide wheels 41 are in a V shape; both ends of the positioning guide wheel 41 are movably installed on a top frame 44 and a bottom frame 45 through rotating shafts; the positioning component 4 further includes a fixed rod 40; a telescopic rod 43 is cooperatively installed at the top of the fixed rod 40; one end of the telescopic rod 43 away from the fixed rod 40 is hingedly connected to the end of the top frame 44; the top frame 44 is hinged to the telescopic rod 43 to facilitate realizing the up-and-down adjustment effect of the telescopic rod 43 installed at the top of the fixed rod 40 during the adjustment of the inclination angle of the positioning guide wheel 41, so as to meet the welding positioning of diversion tubes 2 of different sizes through the adjustment of the inclination angle of the positioning guide wheel 41;

[0034] The bottom of the bottom frame 45 is movably installed on a U-shaped slider 46 through a rotating shaft; the bottom frame 45 is fixedly installed on the push rod of an electric push cylinder 42; one end of the electric push cylinder 42 away from the bottom frame 45 is movably connected to the fixed rod 40; grinding components 3 and hoisting components 7 are respectively arranged at both ends of the positioning component 4; among them, the hoisting component 7 is located at the feeding end of the positioning component 4; when the electric push cylinder 42 drives the bottom frame 45 to adjust, the U-shaped slider 46 ensures that the bottom frame 45 will not shift, thereby effectively ensuring the contact between the positioning guide wheel 41 and the surface of the diversion tube 2 during transmission and ensuring the positioning efficiency;

[0035] The hoisting component 7 includes a hanging plate 73; the hanging plate 73 is arc-shaped, and being arc-shaped facilitates fitting with the inner wall of the notch of the diversion tube 2, so as to ensure that the notch of the diversion tube 2 always faces upward, and the hanging plate 73 is fixedly installed at the end of a cross plate 71; the end of the cross plate 71 away from the hanging plate 73 is cooperatively installed with a second rodless cylinder 70; the second rodless cylinder 70 is fixedly installed on an adjustment slider 72; the adjustment slider 72 is slidably installed on a slide rail on the frame body 1; through the cooperation between the hanging plate 73 and the notch of the diversion tube 2, it effectively ensures that the notch of the diversion tube 2 will not shift during transmission, thereby effectively ensuring the welding efficiency;

[0036] By adopting the above technical solutions, first, the steel plate is shaped by a shaping machine, and the notch of the shaped diversion tube faces upward. Then, through the transmission of the shaping machine, the diversion tube 2 is transmitted into the welding positioning system. During transmission, the diversion tube 2 first passes through the hanging plate 73 at the bottom of the cross plate 71, and the hanging plate 73 is located inside the notch. In this way, during transmission, it is ensured that the notch of the diversion tube 2 will not shift, ensuring the welding quality;

[0037] Please refer to Figures 1-5; One end of the positioning component 4 away from the hoisting component 7 is fitted with a grinding component 3; the grinding component 3 includes a mounting plate 31; two runners facilitating the rotation of the grinding belt 33 are arranged on one side of the mounting plate 31; one of the runners is fixedly connected to a driving motor 34; the end of the mounting plate 31 away from the side where the grinding belt 33 is arranged is fitted with a first rodless cylinder 32; the first rodless cylinder 32 is fixedly mounted at the end of the workbench of the frame body 1 through an L-shaped vertical plate 30; when there is still welding slag at the welded joint of the notch of the conduit 2 after the welding of the conduit 2 is completed, the driving motor 34 drives the runner on the mounting plate 31 to rotate, thereby effectively realizing the grinding of the welding slag on the conduit 2 by the grinding belt 33, and the first rodless cylinder 32 drives the mounting plate 31 to move up and down, thereby effectively ensuring that the grinding belt 33 grinds conduits 2 of different sizes;

[0038] In this embodiment, a welding torch 5 is fitted on the top of the positioning component 4; the welding torch 5 is fixedly mounted on a moving plate 60 in an adjusting component 6; the moving plate 60 in the adjusting component 6 is slidably mounted on a longitudinal slide rail 64 arranged on an adjusting cylinder 67 through a slider 65; the welding of the conveyed conduit 2 is realized by the welding torch 5, and during the welding process, the position of the welding torch 5 is effectively adjusted through the adjusting component 6, thereby ensuring the welding quality;

[0039] By adopting the above technical solution, the conduit 2 is conveyed into the positioning component 4 again, and the conduit 2 passes between multiple groups of two symmetric positioning guide wheels 41. The arc surface of the positioning guide wheel 41 contacts the outer wall of the conduit 2 to realize the conveying effect. When conveying conduits 2 of different sizes, an electric push cylinder 42 movably mounted on a fixed rod 40 drives a chassis 45 to move backward, the chassis 45 pulls the bottom of the positioning guide wheel 41 to move backward, and at this time, the top of the positioning guide wheel 41 moves obliquely upward. The top frame 44 and the telescopic rod 43 ensure the stability of the positioning guide wheel 41 during the adjustment of the inclination angle, thereby realizing the adjustment of the inclination angle of the positioning guide wheel 41, and effectively adjusting the distance between two symmetric positioning guide wheels 41, so as to meet the welding requirements of conduits 2 of different sizes;

[0040] Please refer to Figures 1-8 ; In this embodiment, the adjusting cylinder 67 is slidably mounted on one side of a fixed frame 62; and is connected to a lead screw 66 in cooperation; one end of the lead screw 66 extends to the outside of the fixed frame 62 and is fixedly mounted with a stepping motor 61;

[0041] At one end of the frame body 1 away from the positioning assembly 4, two vertical rods are fixedly installed. A welding controller 63 is placed between the two vertical rods. The horizontal adjustment of the welding torch 5 is realized by driving the lead screw to rotate through the stepping motor 61. At the same time, when welding the diversion pipes 2 with different diameters, the longitudinal adjustment of the moving plate 60 is realized by adjusting the cylinder 67, so as to effectively adjust the distance between the welding torch 5 and the notch of the diversion pipe 2, thus effectively ensuring the welding quality.

[0042] By adopting the above technical solution, when adjusting the distance between the two positioning guide wheels 41, the electric push cylinder 42 drives the chassis 45 to slide backward through the U-shaped slider 46, and at the same time, the telescopic rod 43 at the top of the fixed rod 40 moves upward, so that the inclination angle of the positioning guide wheel 41 becomes smaller, thus effectively increasing the distance between the two symmetric positioning guide wheels 41, and effectively realizing the welding positioning of the diversion pipe 2 with a larger size.

[0043] Please refer to Figures 1-9 ; In this embodiment; the mounting plate 31 and the first rodless cylinder 32 are fixedly installed on the frame body 1 through the L-shaped vertical plate 30; the stability of the grinding belt 33 for grinding the diversion pipe 2 is effectively ensured through the L-shaped vertical plate 30.

[0044] Both the top frame 44 and the chassis 45 are bent, and the surfaces of the top frame 44 and the chassis 45 where the positioning guide wheels 41 are installed are parallel; this effectively ensures the stable welding positioning of the positioning guide wheels 41 for the diversion pipe 2 in transmission, thus ensuring the work efficiency and quality.

[0045] The surface of the positioning guide wheel 41 is arc-shaped, and the arc surfaces of the two symmetric positioning guide wheels 41 are in contact with the outer wall of the diversion pipe 2; in this way, during positioning, through the adjustment of the chassis 45 by the electric push cylinder 42, the extrusion of the diversion pipe 2 is effectively carried out. At the same time, during the extrusion process, the distance between the notches on the diversion pipe 2 is also effectively reduced, which is convenient for better welding treatment.

[0046] By adopting the above technical solution, when the diversion pipe 2 in transmission passes under the welding torch 5, the welding treatment of the notch at the top of the diversion pipe 2 is effectively realized through the welding torch 5. During the welding process, the welding controller 63 is used to precisely control the welding torch 5 to ensure the welding quality. During the welding process, the stepping motor 61 drives the lead screw 66 to rotate, so as to realize the horizontal sliding of the adjusting cylinder 67 along the fixed frame 62. Through the adjusting cylinder 67, the moving plate 60 can also be adjusted up and down along the longitudinal slide rail 64 through the slider 65, so as to effectively meet the welding requirements for diversion pipes 2 of different sizes.

[0047] Furthermore, after welding is completed, the diversion pipe 2 is transported to the bottom of the grinding assembly 3. The driving motor 34 installed on the mounting plate 31 drives the rotating wheel to rotate, so that the grinding belt 33 on the rotating wheel can grind the welding joint of the diversion pipe 2. The mounting plate 31 is movably mounted on the first rodless cylinder 32 at a position away from the end, and the first rodless cylinder 32 is used to adjust the mounting plate 31 up and down, so as to effectively make the grinding belt 33 contact and grind the welding joints of the diversion pipes 2 with different sizes, thus ensuring the quality of the diversion pipes 2;

[0048] The working principle of the present invention is as follows: First, the steel plate is shaped by a shaping machine. After shaping, the diversion pipe has its notch facing upward. Then, through the transmission of the shaping machine, the diversion pipe 2 is transported into the welding positioning system. During the transportation process, the diversion pipe 2 first passes through the hanging plate 73 at the bottom of the cross plate 71, and the hanging plate 73 is located inside the notch. In this way, during the transportation process, it is ensured that the notch of the diversion pipe 2 will not shift, thus ensuring the welding quality;

[0049] Then, the diversion pipe 2 is transported into the positioning assembly 4, and the diversion pipe 2 passes between multiple groups of two symmetric positioning guide wheels 41. The arc surface of the positioning guide wheel 41 contacts the outer wall of the diversion pipe 2 to achieve the transportation effect. When transporting diversion pipes 2 with different sizes, the electric push cylinder 42 movably installed on the fixed rod 40 drives the chassis 45 to move backward, and the chassis 45 pulls the bottom of the positioning guide wheel 41 to move backward. At this time, the top of the positioning guide wheel 41 moves obliquely upward. The top frame 44 and the telescopic rod 43 ensure the stability of the positioning guide wheel 41 during the inclination angle adjustment, so as to adjust the inclination angle of the positioning guide wheel 41, and thus effectively adjust the distance between the two symmetric positioning guide wheels 41, so as to meet the welding requirements of diversion pipes 2 with different sizes;

[0050] When adjusting the distance between the two positioning guide wheels 41, the electric push cylinder 42 drives the chassis 45 to slide backward through the U-shaped slider 46, and at the same time, the telescopic rod 43 at the top of the fixed rod 40 moves upward, so that the inclination angle of the positioning guide wheel 41 becomes smaller, thus effectively increasing the distance between the two symmetric positioning guide wheels 41, and effectively realizing the welding positioning of the diversion pipe 2 with a larger size;

[0051] When the diversion pipe 2 in transportation passes under the welding torch 5, the welding torch 5 effectively welds the notch at the top of the diversion pipe 2. During the welding process, the welding controller 63 is used to precisely control the welding torch 5 to ensure the welding quality. During the welding process, the stepping motor 61 drives the lead screw 66 to rotate, so as to adjust the cylinder 67 to slide horizontally along the fixed frame 62. The adjusting cylinder 67 can also be used to adjust the moving plate 60 to move up and down along the longitudinal slide rail 64 through the slider 65, so as to effectively meet the welding requirements of diversion pipes 2 with different sizes;

[0052] After welding is completed, the diversion pipe 2 is transported to the bottom of the grinding assembly 3. The driving motor 34 installed on the mounting plate 31 drives the rotating wheel to rotate, so that the grinding belt 33 on the rotating wheel can grind the welded joint of the diversion pipe 2. The mounting plate 31 is fitted to the first rodless cylinder 32 at a position away from the end, and the up-and-down adjustment of the mounting plate 31 is realized through the first rodless cylinder 32, so as to effectively make the grinding belt 33 contact and grind the welded joints of the diversion pipes 2 with different sizes, thus ensuring the quality of the diversion pipe 2.
