Description

Technical Field

[0001] The invention belongs to the technical field of welding equipment, and in particular relates to a plasma arc welding machine for producing ladle covers and a processing method thereof. Background Art

[0002] In the steel smelting industry, ladle capping is an important process. The welding quality directly affects the sealing performance, service life and safety of the ladle. Currently, the commonly used welding methods in ladle capping welding operations include manual arc welding and traditional gas shielded welding.

[0003] Manual arc welding relies on the welder to hold the welding gun to operate, which has many problems. First, the welding quality is highly dependent on the welder's personal skill level and experience. The welding quality varies greatly between different welders, making it difficult to ensure the consistency of welding quality. Second, manual operation is inefficient and cannot meet the needs of large-scale production. Moreover, during the welding process, welders are exposed to high temperatures, strong light and welding smoke for a long time. The working environment is harsh and poses a serious threat to the welder's health.

[0004] Authorization publication number "CN216227494U" records a fully automatic plasma arc welding machine, including a welding machine body, a connecting plate provided on the front side of the welding machine body, a structure for shielding strong light provided at the bottom of the connecting plate, the structure for shielding strong light including a fixed plate provided at the bottom of the connecting plate, an adjustment plate provided at the bottom of the fixing plate, a fixed block fixedly connected to the left side of the adjustment plate, a light shielding plate movably connected to the left side of the front and rear sides of the fixed block via hinges, a cross plate fixedly connected to the top of the light shielding plate, and a fixed sleeve fixedly connected to the left side of the light shielding plate. The present utility model solves the problem that plasma arc welding machines generate strong light during welding by providing a pull-out fixing pin, adjusting the height of the light shielding plate, and inserting the fixing pin into the adjustment hole, while existing plasma arc welding machines are unable to shield the strong light and require users to hold a protective mask for protection.

[0005] The above patent has certain limitations when used. During the welding process, due to the lack of effective steel positioning measures, it is difficult to accurately position the ladle and the cover parts to be welded, which can easily cause the steel to deform during welding, resulting in excessive gaps between parts, affecting the welding quality. In addition, the position adjustment range of the plasma arc welding machine is limited, and it is impossible to achieve flexible adjustment of the entire area. It is difficult to effectively weld some welds with tricky angles on the ladle cover. At the same time, during the welding operation, the angle of the ladle cover cannot be flexibly adjusted, which further increases the difficulty of the welding operation and makes the welding process extremely inconvenient. Summary of the Invention

[0058] The plasma arc welding machine for producing a ladle cover is used in any one of the above-mentioned methods, characterized in that it includes the following steps:

[0059] S1. Workpiece positioning and angle adjustment:

[0060] Place the ladle cover on the welding table, calibrate the position with the mounting plates at both ends of the support seat as the reference, start the fourth motor, and its power drives the four transmission rods to rotate through the fourth transmission gear and the second transmission belt. The first bevel gear is engaged with the second bevel gear, driving the third screw to rotate, causing the second nut to drive the second movable plate to slide, and the clamping plate is pushed through the connecting rod, so that the clamping block clamps the four corners of the ladle cover;

[0061] Rotate the adjustment bolt to fine-tune the clamping block pressure to ensure that the workpiece is fixed and deformed. At the same time, the clamping status is confirmed by the intelligent monitoring and recording device at the bottom of the mounting cover to ensure the clearance of corners.

[0062] According to the position of the weld, the first motor is started, which engages with the second transmission gear through the first transmission gear, drives the telescopic rod to move, and the telescopic rod pushes the semicircular ball, so that the support platform can achieve multi-dimensional angle adjustment through the cooperation of the universal ball and the universal joint ball sleeve;

[0063] The laser vision sensor scans the weld in real time, and the control system automatically calculates the optimal angle and locks it to keep the weld perpendicular to the ion arc;

[0064] S2. Welding machine positioning and welding:

[0065] The ion arc welding machine has a built-in laser vision sensor that scans the weld seam, generates three-dimensional trajectory data, and starts the second and third motors to respectively drive the second and first screw rods to rotate. The first nut drives the first movable plate to move along the horizontal X and Y axes, so that the sliding sleeve initially moves the ion arc welding machine body to the area near the weld seam.

[0066] The limiting plates on the rear and right sides guide the first movable plate to ensure horizontal positioning accuracy;

[0067] The six-axis linkage robot arm, according to the control system instructions, accurately aligns the ion arc welding machine body with the weld seam through fine movement of six degrees of freedom. The L-shaped limit rod limits the vertical position of the sliding sleeve to ensure three-dimensional movement stability.

[0068] During the welding process, the laser vision sensor monitors the weld deviation in real time, and the control system synchronously adjusts the movement of the six-axis linkage robot to ensure that the ion arc moves along the weld trajectory;

[0069] S3. Waste disposal and workpiece removal:

[0070] The slag and metal debris produced by welding fall into the collection trough at the top of the support base. Its semicircular concave structure facilitates the waste to converge to the center. The fifth motor drives the spiral transmission blade to rotate, pushing the waste along the collection trough to the outlet for centralized processing.

[0071] Intelligent monitoring and recording equipment collects welding current, voltage, gas flow and other parameters and welding video in real time, and stores the data in the control system for traceability;

[0072] After all welds are completed, the fourth motor reverses, driving the third screw to rotate in the opposite direction, so that the clamp releases the ladle cover, the operator removes the workpiece, and the welding operation is completed.

[0073] Compared with the prior art, the present invention has the following beneficial effects:

[0074] 1. In this solution, four sets of corner clamping assemblies are used to clamp and fix the four corners of the ladle cover. The fourth motor is started, and the power is transmitted to the third screw through the transmission component, so that the second nut drives the second movable plate to slide. The clamping plate is pushed by the connecting rod, so that the clamping block clamps the corners. The adjusting bolt can also be rotated to fine-tune the clamping block pressure to ensure that the workpiece is fixed and there is no deformation. At the same time, the clamping status is confirmed by the intelligent monitoring and recording equipment.

[0075] The welding mechanism consists of a second screw, a first screw, a first nut, a first movable plate, a sliding sleeve, and a six-axis linkage robotic arm. The second motor and the third motor drive the second screw and the first screw to rotate respectively, driving the first movable plate to move along the horizontal X and Y axes. The sliding sleeve initially moves the ion arc welding machine body to the vicinity of the weld seam. Then, through the six degrees of freedom of the six-axis linkage robotic arm, the ion arc welding machine body is precisely aligned with the weld seam to achieve full-area adjustment.

[0076] The adjustment mechanism consists of a universal sphere, a support table, a fixed plate, a first motor, a first transmission gear, a second transmission gear, a telescopic rod, a semi-circular ball, a universal joint ball sleeve, etc. When the first motor is started, the telescopic rod is driven to move through gear engagement, pushing the semi-circular ball, so that the support table can achieve multi-dimensional angle adjustment through the cooperation of the universal sphere and the universal joint ball sleeve. The laser vision sensor scans the weld in real time, and the control system automatically calculates the optimal angle and locks it to keep the weld perpendicular to the ion arc. The ion arc welding machine body has built-in laser vision sensors and image processing technology, which can scan the weld in real time, generate trajectories, monitor offsets and adjust them; the intelligent monitoring and recording equipment collects welding current, voltage, gas flow and other parameters and welding videos in real time, and stores the data for traceability; the automatic waste collection system realizes centralized waste processing through collection troughs and spiral transmission blades.

[0077] 2. In this solution, through the coordinated design of four sets of corner clamping components and transmission parts, the fourth motor drives the third screw to rotate, and the clamping blocks synchronously clamp the four corners of the ladle cover through the connecting rod mechanism. The pressure is fine-tuned with the adjusting bolts, and the clamping status is confirmed in real time with the intelligent monitoring and recording equipment. This effectively solves the deformation and gap problems caused by inaccurate steel positioning in traditional welding, ensures that there is no deformation when the workpiece is fixed, and provides a basic guarantee for welding quality. At the same time, the four sets of clamping components are synchronously driven by the transmission toothed belt and bevel gears, which ensures the uniformity and consistency of the clamping force and improves the positioning accuracy.

[0078] 3. In this solution, the staggered layout of the second and first screw rods in the welding mechanism, combined with the six-axis linkage robot arm and L-shaped limit support rod, realizes horizontal X and Y axis movement and vertical limitation through the second and third motor drives. Combined with laser vision sensors and image processing technology, it can generate a three-dimensional welding trajectory and adjust the welding gun position in real time; the adjustment mechanism uses a universal sphere and a telescopic rod combination to achieve multi-dimensional adjustment of the ladle cover from vertical tilt of 0° to 45° and horizontal rotation of 0° to 360°, so that the weld and the ion arc are always perpendicular, effectively solving the problems of limited position adjustment range of traditional equipment and difficulty in welding welds at tricky angles, realizing full-area precision welding and greatly improving welding efficiency and adaptability.

DETAILED DESCRIPTION

[0088] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0089] Example 1

[0090] See also Figure 1-Figure 7 , the present invention provides the following technical solutions:

[0091] A plasma arc welding machine for producing ladle covers, comprising:

[0092] Support base 1, the top of the support base 1 is fixedly connected to a welding platform 102, the top four corners of the welding platform 102 are fixedly connected to the first support plate 103, and the outer surfaces of the two first support plates 103 at the bottom are respectively fixedly connected to the third motor 309 and the second motor 308;

[0093] Two connecting plates 301, both of which are fixedly connected to one side end of two first support plates 103 on the left side;

[0094] The ion arc welding machine body 3011 is provided on the upper side of the welding table 102;

[0095] The machine also includes a welding mechanism 3, which is provided on the upper side of the first support plate 103 and is used for adjusting the position of the ion arc welding machine body 3011 in the entire area to weld the ladle cover;

[0096] The adjusting mechanism 2 is provided at the center of the welding platform 102 and is used to adjust the angle of the welding ladle cover.

[0097] In a specific embodiment of the present invention, the welding table 102 serves as a working platform for ladle cover welding, providing a stable support surface for the welding operation.

[0098] The first support plate 103 provides structural support for the welding mechanism 3 and the adjustment mechanism 2 to ensure that each component is firmly installed.

[0099] The third motor 309 and the second motor 308 respectively provide power for the different motion axes of the welding mechanism 3, driving the welding mechanism 3 to achieve multi-dimensional movement. Driven by the third motor 309 and the second motor 308, the ion arc welding machine body 3011 can move freely in three-dimensional space to cover various welding positions of the ladle cover, including welds at difficult angles. The welding mechanism 3 is responsible for adjusting the position of the ion arc welding machine body 3011, while the adjustment mechanism 2 is responsible for adjusting the angle of the ladle cover. Working together, the two can achieve high-quality welding of welds at any position and angle on the ladle cover.

[0100] For details, please refer to Figure 1-Figure 7 , the welding mechanism 3 includes:

[0101] A second screw rod 305 is rotatably connected to two of the first support plates 103 located at the lower side, and an output end of the second motor 308 is fixedly connected to one end of the second screw rod 305;

[0102] The first screw rod 302 is rotatably connected to the two first support plates 103. The output end of the third motor 309 is fixedly connected to one end of the first screw rod 302. The second screw rod 305 is higher than the horizontal line of the first screw rod 302 and is staggered therebetween.

[0103] Two first nuts 303 , the two first nuts 303 are respectively threadedly connected to the circumferential surfaces of the two first screw rods 302 ;

[0104] Two first movable plates 304 , the two first movable plates 304 are respectively fixedly connected to the circumferential surfaces of the two first nuts 303 , and the two first movable plates 304 are staggered in height;

[0105] A sliding sleeve rod 306 slidably connected to the two first movable plates 304 ;

[0106] A six-axis linkage robot arm 3010 is mounted on the bottom end of the sliding sleeve 306. An ion arc welding machine body 3011 is mounted on the end of the six-axis linkage robot arm 3010. The ion arc welding machine body 3011 is equipped with a built-in laser vision sensor and image processing technology. The ion arc welding machine body 3011 is connected to an external shielding gas supply device and a gas flow control device through a pipeline.

[0107] An L-shaped limiting support rod 307 is rotatably connected to the top of the welding table 102, and a sliding sleeve rod 306 is slidably connected to the outer surface of the L-shaped limiting support rod 307;

[0108] Four third support plates 7, which are respectively fixedly connected to both ends of the support base 1;

[0109] A fourth motor 407, the fourth motor 407 is fixedly connected to the bottom end of one of the third support plates 7;

[0110] Four sets of edge and corner clamping assemblies 4 are provided at both ends of the support seat 1 and are used for clamping the ladle and covering it.

[0111] In this embodiment, before welding the ladle lid, the fourth motor 407 is activated to drive the four sets of corner clamping assemblies 4 to clamp the corners of the ladle lid and stabilize the workpiece. The operator sets the welding parameters through the external control system and places the ladle lid in the appropriate position on the welding table 102.

[0112] When welding starts, the laser vision sensor built into the ion arc welding machine body 3011 starts working, scanning the weld, collecting image information and transmitting it to the control system. The control system uses image processing technology to analyze the weld position, shape and size and generate a welding trajectory.

[0113] At the same time, the second motor 308 drives the second screw rod 305 to rotate, driving the first movable plate 304, sliding sleeve rod 306 and other components connected thereto to move in a horizontal direction; the third motor 309 drives the first screw rod 302 to rotate, so that the first movable plate 304 moves in another horizontal direction. The two cooperate to realize the two-dimensional movement of the welding mechanism 3 in the horizontal plane, and preliminarily adjust the ion arc welding machine body 3011 to a rough position close to the weld.

[0114] Subsequently, the six-axis robotic arm 3010 performs multi-dimensional precision movements according to the welding trajectory generated by the control system, driving the ion arc welding machine body 3011 for precise positioning, accurately aligning the ion arc with the weld seam. During the welding process, the ion arc welding machine body 3011 continuously monitors the changes in the weld seam position using a laser vision sensor and feeds this data back to the control system, which adjusts the movement of the six-axis robotic arm 3010 in real time to ensure that the ion arc always moves along the weld seam. Simultaneously, an external shielding gas supply device and a gas flow control device deliver shielding gas to the ion arc welding machine body 3011 via a pipeline.

[0115] After completing one weld, the welding mechanism 3 moves to the next weld location through the coordinated movement of the second screw 305, the first screw 302, and the six-axis linkage robot arm 3010. The welding process is repeated until the entire ladle cover is welded. After welding is completed, the motors and equipment are turned off, the corner clamping assembly 4 is released, and the welded ladle cover is removed.

[0116] For details, please refer to Figure 6 , wherein a set of corner clamping components 4 includes:

[0117] A second support plate 4013, the second support plate 4013 is fixedly connected to the top of one of the mounting covers 9;

[0118] A protective cover 8 is fixedly connected to the top of one of the mounting covers 9;

[0119] A third screw rod 405 is rotatably connected to the second support plate 4013 and the protective cover 8;

[0120] A second nut 4011 , the second nut 4011 being threadedly connected to a circumferential surface of the third screw rod 405 ;

[0121] A second movable plate 4010, the second movable plate 4010 is fixedly connected to the circumferential surface of the second nut 4011, and the second movable plate 4010 is slidably connected to the top end of one of the mounting covers 9;

[0122] A support block 406, the support block 406 is fixedly connected to the circumferential surface of the protective cover 8;

[0123] Two connecting rods 408, both connecting rods 408 are rotatably connected to both ends of the support block 406;

[0124] Clamping plate 409, which is rotatably connected to the second movable plate 4010 and the two connecting rods 408;

[0125] An adjusting bolt 4012 is rotatably connected to the clamping plate 409 and is threadedly connected to an external hexagonal nut;

[0126] A clamping block 402, the clamping block 402 being fixedly connected to the circumferential surface of the adjusting bolt 4012;

[0127] The transmission component 5 is arranged on the upper side of the four third support plates 7, and the transmission component 5 is used to drive the four groups of edge and corner clamping components 4 to operate simultaneously.

[0128] In this embodiment, when the ladle cover needs to be welded, the control system first starts the fourth motor 407. The power of the fourth motor 407 is synchronously transmitted to the third screw rods 405 of the four sets of corner clamping assemblies 4 through the transmission component 5, so that the four third screw rods 405 start to rotate simultaneously.

[0129] As the third screw 405 rotates, the second nut 4011, which is threadedly engaged with the screw, moves along the screw axis, driving the second movable plate 4010 fixed to the second nut 4011 to slide on the top of the mounting cover 9. The movement of the second movable plate 4010 is transmitted to the clamping plate 409 via the connecting rod 408. Due to the fixed fulcrum of the support block 406, the clamping plate 409 swings around the connection point with the connecting rod 408, thereby causing the clamping block 402 fixed to the clamping plate 409 to move closer to the corner of the ladle cover.

[0130] Once the clamping block 402 contacts the corner of the ladle cover, the third screw 405 is rotated continuously, gradually tightening the clamping block 402 and applying a clamping force to the corner of the ladle cover. At this point, the position of the clamping block 402 can be fine-tuned by rotating the adjusting bolt 4012 to ensure full contact with the corner of the ladle cover and apply appropriate pressure, ensuring that the ladle cover does not shift or deform during the welding process.

[0131] The four sets of corner clamping assemblies 4 operate synchronously to clamp the corners of the ladle cover from four directions, so that it is firmly fixed on the welding table 102. During the welding process, this stable clamping state can effectively prevent deformation and excessive gaps between the steel materials, thereby ensuring welding quality.

[0132] After welding is completed, the fourth motor 407 rotates in the reverse direction, driving the third screw rod 405 to rotate in the opposite direction, so that the clamping block 402 gradually loosens the corners of the ladle cover. The operator can then remove the welded ladle cover from the welding table 102.

[0133] For details, please refer to Figure 1-Figure 7 , the transmission component 5 includes:

[0134] Four transmission rods 401, the four transmission rods 401 are rotatably connected to the four mounting covers 9 respectively;

[0135] Four first bevel gears 403, the four first bevel gears 403 are respectively fixedly connected to the circumferential surfaces of the four transmission rods 401;

[0136] Four second bevel gears 404 are fixedly connected to the circumferential surfaces of four third screw rods 405 respectively. The first bevel gear 403 of the screw rod and the second bevel gear 404 are meshed with each other, wherein the four second bevel gears 404 on the left and right sides have opposite angles;

[0137] Four fourth transmission gears 503 are fixedly connected to the circumferential surfaces of the four transmission rods 401, and one of the fourth transmission gears 503 is fixedly connected to the output end of the fourth motor 407.

[0138] Two second transmission toothed belts 504 , the second transmission toothed belts 504 are respectively engaged with the circumferential surfaces of the four fourth transmission gears 503 ;

[0139] The cavity opening is opened at one side end of the support base 1;

[0140] A first transmission toothed belt 501 is provided in the cavity;

[0141] The third transmission gear 502 is fixedly connected to the circumferential surfaces of two of the first transmission toothed belts 501 located on the front side, and the first transmission toothed belts 501 are transmission-engaged with the circumferential surfaces of the two third transmission gears 502 .

[0142] In this embodiment, when the ladle lid needs to be clamped, the operator starts the fourth motor 407. The output shaft of the fourth motor 407 drives the fourth transmission gear 503 fixedly connected thereto to rotate. The fourth transmission gear 503 transmits power to the other three fourth transmission gears 503 via the second transmission belt 504, causing the four transmission rods 401 to rotate simultaneously.

[0143] The rotation of the transmission rod 401 rotates the first bevel gear 403 fixed thereto. The first bevel gear 403 meshes with the second bevel gear 404, converting horizontal rotational motion into vertical rotational motion, thereby driving the third screw rod 405. Because the left and right second bevel gears 404 are at opposite angles, the left and right third screw rods 405 rotate in opposite directions, but both can move the second nut 4011 inward, thereby driving the clamping plate 409 and the clamping block 402 toward the corner of the ladle cover, achieving a clamping action.

[0144] At the same time, the front transmission rod 401 transmits power to the rear transmission rod 401 through the meshing of the third transmission gear 502 fixed thereto and the first transmission belt 501, causing the rear corner clamping assembly 4 to also operate synchronously. In this way, the four sets of corner clamping assemblies 4 can simultaneously clamp the four corners of the ladle cover, ensuring that the ladle cover remains stable during the welding process.

[0145] For details, please refer to Figure 1-Figure 5 , the regulating mechanism 2 includes:

[0146] Universal ball 209, which is fixedly connected to the central depression of the support platform 201;

[0147] Support platform 201, support platform 201 is provided on the upper side of fixed plate 202;

[0148] A fixed plate 202, the fixed plate 202 is fixedly connected to the top of the universal sphere 209;

[0149] A first motor 204 is mounted on the bottom end of the fixing plate 202;

[0150] A first transmission gear 203 , the first transmission gear 203 is fixedly connected to the output end of the first motor 204 ;

[0151] The second transmission gear 205 is rotatably connected to the top of the fixed plate 202. The second transmission gear 205 is meshed with the first transmission gear 203. The support platform 201 and the fixed plate 202 are respectively fixedly connected to the adjacent ends thereof with a universal ball 209 and a universal joint ball sleeve 208. The universal ball 209 and the universal joint ball sleeve 208 match each other, and the universal ball 209 is slidably connected to the universal joint ball sleeve 208.

[0152] Two telescopic rods 206 are fixedly connected to the top of the second transmission gear 205 , and the tops of the two telescopic rods 206 are fixedly connected with a semicircular ball 207 .

[0153] In this embodiment, before welding the ladle cover, the operator starts the first motor 204 through the control system according to the weld position and welding process requirements. The first motor 204 starts to run, and its output end drives the first transmission gear 203 to rotate.

[0154] Since the first transmission gear 203 is meshed with the second transmission gear 205 , the rotation of the first transmission gear 203 is transmitted to the second transmission gear 205 , causing the second transmission gear 205 to rotate on the top of the fixing plate 202 .

[0155] Along with the rotation of the second transmission gear 205, the two telescopic rods 206 fixed on its top start to move. The telescopic rods 206 push the semicircular balls 207 connected thereto by telescoping or swinging, and the semicircular balls 207 then act on the support platform 201.

[0156] Because the support platform 201 and the fixed plate 202 are connected by the universal ball 209 and the universal joint ball sleeve 208, under the push of the telescopic rod 206, the support platform 201 can achieve angle adjustment in multiple directions within the limit range of the universal joint ball sleeve 208 with the universal ball 209 as the center.

[0157] For example, when the two telescopic rods 206 extend to different lengths, the support platform 201 will tilt; when the telescopic rods 206 swing, the support platform 201 will rotate a certain angle in the horizontal direction. In this way, the ladle cover is adjusted to the appropriate welding angle, so that the welding robot arm drives the ion arc welding machine body 3011 to perform precise welding.

[0158] When the welding angle adjustment is completed, the first motor 204 stops running. At this time, the telescopic rod 206 remains fixed, and relies on the cooperation of the universal ball 209 and the universal joint ball sleeve 208 to maintain the current angle of the support platform 201, providing a stable workpiece placement platform for the welding operation.

[0159] For details, please refer to Figure 1-Figure 7 The outside of the four first support plates 103 is movably connected to a mounting cover 9 , and the bottom of the mounting cover 9 is installed with an intelligent monitoring and recording device 10 .

[0160] In this embodiment, a mounting cover 9, which is movably attached to the four first support plates 103, protects the internal components of the welding mechanism 3. An intelligent monitoring and recording device 10, mounted at the bottom of the mounting cover 9, monitors various welding parameters, such as welding current, voltage, and speed, in real time, while simultaneously recording video images of the entire welding process. During welding, the intelligent monitoring and recording device 10 transmits the collected data and images to the control system, allowing the operator to view the welding status in real time through the control system's human-machine interface.

[0161] For details, please refer to Figure 1-Figure 5 A collecting groove 101 is provided at the top of the support seat 1. The center of the collecting groove 101 is concave semicircular. The spiral transmission blade 801 is rotatably connected to the front and rear inner walls of the collecting groove 101. The front end of the support seat 1 is fixedly connected to the fifth motor 6, and the output end of the fifth motor 6 is fixedly connected to one end of the spiral transmission blade 801.

[0162] In this embodiment: the slag, metal debris and other waste materials generated during the welding process fall into the semicircular concave groove of the collection trough 101 due to gravity. The semicircular structure facilitates the waste to gather toward the center; the fifth motor 6 drives the spiral transmission blade 801 to rotate, and through the pushing action of the spiral blade, the waste is transmitted along the collection trough 101 to one end, realizing the automatic collection and centralized treatment of the waste.

[0163] For details, please refer to Figure 1-Figure 7, located at the rear and right sides, one end of the two first support plates 103 are fixedly connected to the limiting plate 11, and the two first movable plates 304 are slidably connected to one end of the two limiting plates 11 respectively.

[0164] In this embodiment, the limiting plate 11, fixedly connected at one end to the two first support plates 103 on the rear and right sides, forms a precise sliding guide structure with the two first movable plates 304. When the second motor 308 and the third motor 309 drive the first screw rod 302 and the second screw rod 305 to rotate, the first nut 303 drives the first movable plate 304 to move. At this time, the limiting plate 11 acts as a limiter and guide for the first movable plate 304, restricting it to slide in a specific direction, preventing the first movable plate 304 from deflecting or shaking during movement, and ensuring the horizontal positioning accuracy of the ion arc welding machine body 3011.

[0165] For details, please refer to Figure 1-Figure 2 , both ends of the support base 1 are fixedly connected with a mounting plate 12.

[0166] In this embodiment, the mounting plate 12 is primarily used to define the overall position of the ladle cover. When placing the ladle cover on the welding table 102, the mounting plate 12 serves as a reference boundary, helping the operator quickly position the ladle cover in the proper position and avoiding significant positioning deviations that could affect subsequent welding operations.

[0167] The working principle and use process of the present invention are as follows: after the ladle cover is placed on the welding table 102 and initially positioned using the mounting plates 12 at both ends of the support seat 1, the fourth motor 407 is started, and its power drives the transmission rod 401 to rotate through the fourth transmission gear 503 and the second transmission toothed belt 504, and the first bevel gear 403 is engaged with the second bevel gear 404 to make the third screw rod 405 rotate, driving the second nut 4011 to drive the second movable plate 4010 to slide, and the clamping plate 409 drives the clamping block 402 to clamp the corners of the ladle cover through the connecting rod 408, and at the same time, the adjusting bolt 4012 is rotated to fine-tune the pressure, and the intelligent monitoring and recording device 10 at the bottom end of the installation cover 9 is cooperated to confirm the clamping state; then the first motor 204 is started according to the position of the weld, and the telescopic rod 206 is driven to move through the engagement of the first transmission gear 203 and the second transmission gear 205, and the universal ball 209 is cooperated with the universal joint ball sleeve 208 to make The support platform 201 is tilted or rotated, and the ladle cover is adjusted to an angle perpendicular to the weld and the ion arc and locked; then the built-in laser vision sensor of the ion arc welding machine body 3011 scans the weld to generate a trajectory, starts the second motor 308 and the third motor 309 to drive the second screw 305 and the first screw 302 to rotate, and drives the first movable plate 304 to make the sliding sleeve 306 move the ion arc welding machine body 3011 initially to the vicinity of the weld, and then finely positions it through the six-axis linkage robot arm 3010. During welding, the laser vision sensor tracks the weld offset in real time and adjusts the robot arm movement, while the external protective gas supply device delivers protective gas; during the welding process, the intelligent monitoring and recording equipment 10 collects parameters and videos, and the fifth motor 6 drives the spiral transmission blade 801 to push the waste in the collection tank 101 to the outlet; after welding is completed, the fourth motor 407 reverses to release the clamp 402, and removes the ladle cover.
