Description

Technical Field

[0001] The invention belongs to the technical field of welding, in particular to a ship bulkhead welding device. Background Art

[0002] Ship bulkhead welding equipment is a device used to weld bulkheads without relying on tracks for positioning and movement. It usually has a flexible movable mechanism, such as a wheeled or tracked walking device, which can move freely on the bulkhead surface or nearby supporting structures. It is also equipped with a high-precision welding head and an advanced control system, which can accurately control parameters such as welding position, speed and angle to meet the welding needs of bulkheads of different shapes and sizes.

[0003] In the existing technology, a welding gun is first mounted on a robotic arm or a welding carriage, and the welding path is determined by a preset program or manual teaching. The sensor equipped in the device monitors the weld position and gap in real time, automatically adjusts the welding parameters (such as current, voltage, and wire feeding speed), and uses metal arc welding (MIG / MAG) or plasma welding to form a continuous and dense weld at the joint of the bulkhead plate.

[0004] There are still some problems in the actual application of the above scheme. Although the existing technology can complete the welding work on the ship bulkhead, due to the cutting, welding, grinding and other processes in the construction process of the ship, a large amount of metal debris, welding slag, etc. will be generated. The height and distribution of these welding slags are uneven. When the welding trolley travels on it, the running wheels will shake due to contact with the uneven welding slag. When the welding trolley shakes, it will be transmitted to the welding gun through the mechanical structure, causing the welding arc position and posture to change continuously, which will cause the arc to become unstable. The unstable arc will cause the welding current and voltage to fluctuate, resulting in uneven weld depth and width, and easily produce defects such as pores and slag inclusions, which seriously affect the density and strength of the weld and reduce the quality of the welded joint.

[0010] Preferably, the guide groove consists of a transverse groove, a vertical groove and an oblique groove, and there is a height difference at the intersection of every two grooves. The provision of the second spring facilitates the device to adapt to the height difference between the grooves.

[0015] 1. In the ship bulkhead welding device described in the present invention, when the scraper moves toward the middle, the telescopic column slides in the transverse groove of the guide groove, so the scraper performs horizontal linear motion at this time. When the scraper moves to the intersection of the oblique groove and the transverse groove of the guide groove, since the height of the transverse groove increases from the vertical groove of the guide groove to the oblique groove, the second spring will reset when the telescopic column slides to the intersection of the oblique groove and the transverse groove. At the same time, since an oblique structure is provided at the intersection of the oblique groove and the transverse groove, when the driving motor rotates in the opposite direction, the telescopic column will gradually slide into the oblique groove of the guide groove. At the same time, since the telescopic column slides in the telescopic cylinder, and the telescopic cylinder is fixed at The scraper is on the side, so when the telescopic column moves along the oblique groove of the guide groove, the scraper will be gradually lifted upward by the second baffle. At this time, the bottom of the scraper will gradually move away from the ground, preventing the scraper from pushing debris onto the movement path of the ship welding device tire when resetting. Through the relative movement of the two scrapers, the debris on the driving path of the ship welding device tire can be pushed to the bottom of the smart car, maintaining the flatness of the driving path, thereby improving the stability of the smart car during driving, and then making the ship welding device walk more smoothly, reducing the shaking caused by debris, and ensuring that it travels in a straight line along the predetermined welding trajectory, thereby improving the straightness and accuracy of welding.

[0016] 2. A ship bulkhead welding device described in the present invention, when the telescopic column moves along the guide groove oblique groove to the intersection of the vertical groove, the first spring will be reset because it is not affected by external force, and at the same time, it will drive the scraper to move downward along the inner cavity of the moving block. At this time, the second baffle fixed on the side of the scraper will also move downward, and will resist the top of the sliding column during the movement. However, since the elastic force of the first spring is greater than the elastic force of the third spring, the third spring will be affected by the external force and shrink at this time, and the sliding column will move linearly downward along the limit groove opened on the side wall of the second fixed plate. Since the limit moving rod fixed in the inner cavity of the sliding column slides in the arc guide groove opened at the top of the vertical rod of the swing rod, when the sliding column moves downward, it will resist the arc guide groove through the limit moving rod, pushing the vertical rod of the swing rod to rotate around its axis, thereby driving its transverse rod to swing, and while swinging, it can push the debris at the contact position of the scraper with the ground to the outside of the ship welding device, thereby avoiding the direct contact between the scraper and the debris when the scraper moves downward, thereby increasing the service life of the scraper.

[0017] 3. In the ship bulkhead welding device described in the present invention, when the two moving blocks perform linear motion towards each other, the moving block away from the driving motor will abut against the vertical rod of the piston rod during the movement, and will push the piston rod to move in the direction of the driving motor during the movement. At this time, the piston plate fixed at one end of the transverse rod of the piston rod will move synchronously and continuously squeeze the flux inside the piston cylinder during the movement. Since the nozzle at one end of the piston cylinder and the welding head of the welding gun are in the same horizontal plane, the flux squeezed in the piston cylinder will be sprayed to the weld area through the nozzle, thereby reducing the surface tension of the welding material, making it easier to spread and wet on the weld surface, improving the bonding strength between the welding material and the base material, and thus improving the quality of welding.

[0020] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods. Embodiment 1

[0021] like Figures 1 to 10 As shown, a ship bulkhead welding device according to an embodiment of the present invention comprises a ship welding device 1, wherein the ship welding device 1 comprises an intelligent trolley 101, a welding gun 102 is fixedly connected to the upper portion of the intelligent trolley 101, a reciprocating scraping mechanism 2 is arranged on the side of the ship welding device 1, and a spraying mechanism 3 is arranged on the upper portion of the reciprocating scraping mechanism 2; The reciprocating scraping mechanism 2 includes a bidirectional threaded rod 203 rotatably arranged on the side of the smart car 101, and two scrapers 207 are arranged at the lower part of the bidirectional threaded rod 203. The reciprocating motion of the two scrapers 207 can gather the broken iron filings on the running path of the device to the bottom of the device; A first fixed plate 208 is fixedly connected to the side of the smart car 101, a guide groove 209 is opened inside the first fixed plate 208, a telescopic column 210 is slidably connected inside the guide groove 209, one end of the telescopic column 210 is fixedly connected to a second spring 211, the other end of the second spring 211 is fixedly connected to a telescopic cylinder 212, the telescopic cylinder 212 is fixedly connected to the side wall of the scraper 207, and the telescopic column 210 is slidably connected inside the telescopic cylinder 212.

[0022] Specifically, although the existing technology can complete the welding work on the ship bulkhead, due to the cutting, welding, grinding and other processes in the construction process of the ship, a large amount of metal debris, welding slag, etc. will be generated. The height and distribution of these welding slags are uneven. When the welding trolley travels on it, the running wheels will shake due to contact with the uneven welding slag. When the welding trolley shakes, it will be transmitted to the welding gun 102 through the mechanical structure, causing the welding arc position and posture to change continuously, which will lead to unstable arc. The unstable arc will cause fluctuations in welding current and voltage, resulting in uneven weld penetration and width, and easily produce defects such as pores and slag inclusions, which will seriously affect the density and strength of the weld and reduce the quality of the weld joint.

[0023] Therefore, the present invention solves this problem by setting a corresponding structure. In the ship bulkhead welding device described in the present invention, when the ship welding device 1 is needed to complete the welding work on the ship bulkhead, the intelligent trolley 101 is started. At this time, the intelligent trolley 101 will drive the equipment to move along a predetermined route, and perform welding work on the weld area through the welding gun 102 while moving. However, during the construction of the ship, cutting, welding, grinding and other processes will generate a large amount of metal debris, welding slag, etc., and these welding slags are unevenly accumulated in height and distribution. When the welding trolley travels on it, the walking wheels will shake due to contact with the uneven welding slag. When the welding trolley shakes, it will be transmitted through the mechanical structure. When the welding gun 102 is passed to the welding gun 102, the welding arc position and posture are constantly changing, which will cause the arc to be unstable. The unstable arc will cause the welding current and voltage to fluctuate, resulting in uneven weld penetration and width, and easily produce defects such as pores and slag inclusions, which seriously affect the density and strength of the weld and reduce the quality of the weld joint. When it is necessary to use the ship welding device 1 for welding, the bidirectional threaded rod 203 in the reciprocating scraping mechanism 2 will rotate, and at the same time drive the two scrapers 207 at the bottom to move in opposite directions, so that the debris on the moving path of the welding trolley tire can be pushed to the middle, thereby maintaining the flatness of the moving path of the welding trolley tire, thereby improving the quality of equipment welding.

[0024] In addition, when the scraper 207 moves toward the middle, the telescopic column 210 slides in the transverse groove of the guide groove 209, so the scraper 207 performs horizontal linear motion at this time. When the scraper 207 moves to the intersection of the oblique groove and the transverse groove of the guide groove 209, since the height of the transverse groove is higher and higher from the vertical groove of the guide groove 209 to the oblique groove, the second spring 211 will reset when the telescopic column 210 slides to the intersection of the oblique groove and the transverse groove. At the same time, since an oblique structure is provided at the intersection of the oblique groove and the transverse groove, when the drive motor 202 rotates in the opposite direction, the telescopic column 210 will gradually slide into the oblique groove of the guide groove 209. At the same time, since the telescopic column 210 slides in the telescopic cylinder 212, and the telescopic cylinder 212 is fixed on the scraper 207 is on the side, so when the telescopic column 210 moves along the oblique groove of the guide groove 209, the scraper 207 will be gradually lifted upward by the second baffle 213. At this time, the bottom of the scraper 207 will gradually move away from the ground, preventing the scraper 207 from pushing debris onto the movement path of the tire of the ship welding device 1 when resetting. Through the relative movement of the two scrapers 207, the debris on the driving path of the tire of the ship welding device 1 can be pushed to the bottom of the smart car 101, maintaining the flatness of the driving path, thereby improving the stability of the smart car 101 during driving, and then making the ship welding device 1 walk more smoothly, reducing the shaking caused by debris, and ensuring that it travels in a straight line along the predetermined welding trajectory, thereby improving the straightness and accuracy of welding. Embodiment 2

[0025] like Figures 2 to 10 As shown in Comparative Example 1, another embodiment of the present invention is: like Figure 3 As shown, the reciprocating scraping mechanism 2 described in this embodiment also includes a first baffle 201, and the first baffle 201 is fixedly connected to the side of the intelligent vehicle 101. A driving motor 202 is fixedly connected to the side of the first baffle 201. The output shaft of the driving motor 202 passes through and is rotatably connected to the inside of the first baffle 201. The output shaft of the driving motor 202 is fixedly connected to a bidirectional threaded rod 203. The outer ring surface of the bidirectional threaded rod 203 is threadedly connected to a moving block 204. A guide rod 205 is arranged inside the moving block 204, and the moving block 204 is slidably connected to the outer ring surface of the guide rod 205.

[0026] like Figure 5 As shown, the moving block 204 of this embodiment has an inner cavity, a first spring 206 is fixedly connected to the top of the inner cavity of the moving block 204 , a scraper 207 is fixedly connected to the bottom of the first spring 206 , and the scraper 207 is slidably connected to the inside of the moving block 204 .

[0027] Specifically, when the ship welding device 1 moves to a predetermined position, the drive motor 202 on the side wall of the first baffle 201 is started. When the output shaft of the drive motor 202 rotates, it drives the bidirectional threaded rod 203 fixed thereto to rotate, and at the same time drives the moving block 204 threadedly connected to its outer ring surface to move synchronously. Since the moving block 204 slides on the outer ring surface of the guide rod 205, when the bidirectional threaded rod 203 rotates, the moving blocks 204 arranged at both ends of the bidirectional threaded rod 203 will move synchronously toward the middle, thereby driving the scraper 207 sliding inside the moving block 204 to move synchronously. Since the bottom of the scraper 207 is in contact with the ground, when the scraper 207 moves, it will synchronously push the deposited on the ground to the lower part of the ship welding device 1, thereby improving the flatness of the tire moving path of the smart car 101.

[0028] like Figure 7 As shown, in this embodiment, the scraper 207 side wall is fixedly connected to the second baffle 213, the first fixed plate 208 is fixedly connected to the second fixed plate 214 at the bottom, the second fixed plate 214 side wall is slidably connected to the sliding column 215, the inner ring surface of the sliding column 215 is fixedly connected to the limited movement rod 216, the bottom of the second fixed plate 214 is rotatably connected with a swing rod 219, the top outer ring surface of the swing rod 219 is provided with an arc guide groove 217, the limited movement rod 216 is slidably connected inside the arc guide groove 217, the bottom of the sliding column 215 is fixedly connected to the third spring 218, and the other end of the third spring 218 is fixedly connected to the bottom of the second fixed plate 214.

[0029] Specifically, when the telescopic column 210 moves obliquely along the guide groove 209 to the junction with the vertical groove, the first spring 206 will reset due to the absence of external force. While resetting, it will drive the scraper 207 to move downward along the inner cavity of the moving block 204. At this time, the second baffle 213 fixed to the side of the scraper 207 will also move downward and will abut against the top of the sliding column 215 during the movement. However, since the elastic force of the first spring 206 is greater than that of the third spring 218, the third spring 218 will be affected by the external force and contract at this time, and the sliding column 215 will move downward in a straight line under the influence of the limit groove opened on the side wall of the second fixing plate 214. Since the limit moving rod 216 fixed inside the sliding column 215 slides in the arc-shaped guide groove 217 opened at the top of the vertical rod of the swing rod 219, when the sliding column 215 moves downward, it will abut against the arc-shaped guide groove 217 through the limit moving rod 216, pushing the vertical rod of the swing rod 219 to rotate around its central axis, and then being able to drive its horizontal rod to swing. While swinging, it can push the debris at the contact position between the scraper 207 and the ground to the outside of the ship welding device 1, thus being able to avoid the situation where the scraper 207 directly contacts the debris when moving downward, and further being able to improve the service life of the scraper 207.

[0030] As Fig. 9 and Fig.10 shown, the spraying mechanism 3 in this embodiment further includes a fixed block 301. The fixed block 301 is fixedly connected to the upper part of the first baffle 201. A piston cylinder 302 is fixedly connected inside the fixed block 301. A piston piece 303 is slidably connected inside the piston cylinder 302. One side of the piston piece 303 is fixedly connected to a piston rod 305. The piston rod 305 is composed of a horizontal rod and a vertical rod.

[0031] As Fig. 9 and Fig.10 shown, one side of the piston piece 303 in this embodiment is fixedly connected to a fourth spring 304. The other end of the fourth spring 304 is fixedly connected to the side wall of the piston cylinder 302. The fourth spring 304 is sleeved on the horizontal rod of the piston rod 305. A diversion pipe 306 is fixedly connected through the outer ring surface of the piston cylinder 302. One end of the diversion pipe 306 is fixedly connected through to a liquid storage tank 307. The liquid storage tank 307 is fixedly connected to the top of the fixed block 301.

[0032] Specifically, when the two moving blocks 204 perform linear motion towards each other, the moving block 204 away from the driving motor 202 will abut against the vertical rod of the piston rod 305 during the movement, and will push the piston rod 305 to move in the direction of the driving motor 202 during the movement. At this time, the piston plate 303 fixed at one end of the transverse rod of the piston rod 305 will move synchronously and continuously squeeze the flux inside the piston cylinder 302 during the movement. Since the nozzle at one end of the piston cylinder 302 and the welding head of the welding gun 102 are at the same horizontal plane, the flux squeezed in the piston cylinder 302 will be sprayed to the weld area through the nozzle, thereby reducing the surface tension of the welding material, making it easier to spread and wet on the weld surface, improving the bonding strength between the welding material and the base material, and thus improving the quality of welding.

[0033] Working principle: When the ship welding device 1 moves to a predetermined position, the drive motor 202 on the side wall of the first baffle 201 is started. When the output shaft of the drive motor 202 rotates, it will drive the two-way threaded rod 203 fixed thereto to rotate, and at the same time drive the moving block 204 threadedly connected to its outer ring surface to move synchronously. Since the moving block 204 slides on the outer ring surface of the guide rod 205, when the two-way threaded rod 203 rotates, the moving blocks 204 arranged at both ends of the two-way threaded rod 203 will move synchronously toward the middle, and then can drive the scraper 207 sliding inside the moving block 204 to move synchronously. Since the bottom of the scraper 207 is in contact with the ground, when the scraper 207 moves, it will synchronously push the deposited on the ground to the lower part of the ship welding device 1, thereby improving the flatness of the tire moving path of the smart car 101.

[0034] When the scraper 207 moves toward the middle, the telescopic column 210 slides in the transverse groove of the guide groove 209, so the scraper 207 performs horizontal linear motion at this time. When the scraper 207 moves to the intersection of the oblique groove and the transverse groove of the guide groove 209, since the height of the transverse groove is higher and higher from the vertical groove of the guide groove 209 to the oblique groove, the second spring 211 will reset when the telescopic column 210 slides to the intersection of the oblique groove and the transverse groove. At the same time, since an oblique structure is provided at the intersection of the oblique groove and the transverse groove, when the drive motor 202 rotates in the opposite direction, the telescopic column 210 will gradually slide into the oblique groove of the guide groove 209. At the same time, since the telescopic column 210 slides in the telescopic cylinder 212, and the telescopic cylinder 212 is fixed on the scraper 2 07 side, so when the telescopic column 210 moves along the oblique groove of the guide groove 209, the scraper 207 will be gradually lifted upward by the second baffle 213. At this time, the bottom of the scraper 207 will gradually move away from the ground, preventing the scraper 207 from pushing debris onto the movement path of the tire of the ship welding device 1 when resetting. The relative movement of the two scrapers 207 can push the debris on the driving path of the tire of the ship welding device 1 to the bottom of the smart car 101, maintaining the flatness of the driving path, thereby improving the stability of the smart car 101 during driving, and then making the ship welding device 1 walk more smoothly, reducing the shaking caused by debris, and ensuring that it travels in a straight line along the predetermined welding trajectory, thereby improving the straightness and accuracy of welding.

[0035] When the telescopic column 210 moves along the oblique groove of the guide groove 209 to the intersection of the vertical groove, the first spring 206 will reset due to no influence of external force, and at the same time, it will drive the scraper 207 to move downward along the inner cavity of the moving block 204. At this time, the second baffle 213 fixed on the side of the scraper 207 will also move downward, and will resist the top of the sliding column 215 during the movement. However, since the elastic force of the first spring 206 is greater than the elastic force of the third spring 218, the third spring 218 will shrink under the influence of external force at this time, and the sliding column 215 will be affected by the limiting groove opened on the side wall of the second fixed plate 214. It performs linear motion downward. Since the limiting movable rod 216 fixed in the inner cavity of the sliding column 215 slides in the arc guide groove 217 opened at the top of the vertical rod of the swing rod 219, when the sliding column 215 moves downward, the limiting movable rod 216 will resist the arc guide groove 217, pushing the vertical rod of the swing rod 219 to rotate around its axis, thereby driving its transverse rod to swing, and at the same time, it can push the debris at the contact position of the scraper 207 with the ground to the outside of the ship welding device 1, thereby avoiding the direct contact of the scraper 207 with the debris when moving downward, thereby increasing the service life of the scraper 207.

[0036] When the two moving blocks 204 perform linear motion towards each other, the moving block 204 away from the driving motor 202 will collide with the vertical rod of the piston rod 305 during the movement, and will push the piston rod 305 to move in the direction of the driving motor 202 during the movement. At this time, the piston plate 303 fixed at one end of the transverse rod of the piston rod 305 will move synchronously and continuously squeeze the flux inside the piston cylinder 302 during the movement. Since the nozzle at one end of the piston cylinder 302 and the welding head of the welding gun 102 are at the same horizontal plane, the flux squeezed in the piston cylinder 302 will be sprayed to the weld area through the nozzle, thereby reducing the surface tension of the welding material, making it easier to spread and wet on the weld surface, improving the bonding strength between the welding material and the base material, and thus improving the quality of welding.
