Description

TECHNICAL FIELD

[0001] The application belongs to the technical field of tube-core plate processing, and particularly relates to a tube-core plate automatic welding production equipment with a comb-shaped base plate. BACKGROUND

[0002] In the field of tube-core plate (formed by welding a metal plate and a pipe) production, the welding of the metal plate and the pipe is a core process, and the machining precision and efficiency thereof directly determine the product quality and production capacity. At present, the mainstream tube-core plate welding operation in the industry relies on semi-automatic equipment and manual operation, that is, the metal plate is fixed on a simple tooling table by manual operation, and then the pipe is placed one by one at the preset insertion hole of the metal plate by manual or semi-automatic feeding device, and finally the welding gun is used to weld the connecting points of the pipe and the metal plate. Although some devices with higher automation degree can realize the preliminary linkage of feeding and welding, manual assistance is still needed to adjust the position of the metal plate or the pipe to ensure the precise welding alignment. The overall operation process has a high dependence on manual operation, and it is difficult to meet the production needs of large scale and high rhythm.

[0003] The existing technology has obvious positioning precision defects in the tube-core plate welding process. On the one hand, the traditional equipment lacks a special positioning structure for the pipe and the metal plate, and the pipe is easy to deviate when placed in the insertion hole of the metal plate due to insufficient tooling guidance, resulting in uneven gap between the pipe and the metal plate, and subsequent welding is prone to virtual welding and missed welding problems. On the other hand, most devices adopt the operation mode of "welding gun fixed, metal plate moved", and after completing the welding of one layer of pipe, the whole metal plate and pipe which are not completely fixed need to be lifted to create space for the next layer of welding. During this process, the pipe that is not firmly welded is easy to be displaced due to vibration or gravity, further aggravating the positioning deviation, and ultimately leading to the size precision of the finished product not meeting the standard and a high rework rate.

[0004] In addition, the existing technology also has problems of low operation efficiency and poor space utilization. In terms of efficiency, the feeding, pushing and welding processes of the traditional equipment are loosely connected, and are operated in single stations one after another, which cannot realize the synchronization of multiple processes, and there are many manual intervention links, so the welding capacity per hour is difficult to improve. In terms of space utilization, the existing equipment adopts a horizontal translation method for finished product taking and placing, and needs to reserve enough finished product conveying channels on both sides of the equipment, resulting in a large overall equipment area. Especially in the scene where the production layout of the workshop is compact, the installation and capacity expansion of the equipment are limited, and it is difficult to adapt to the efficient space planning needs of modern workshops.

The whole machine base 1 is a basic frame of the whole equipment and is mainly used for providing a stable mounting carrier for all components, a mounting groove 101 is formed in the center of the top of the whole machine base 1, a substrate base 201 of the substrate assembly 2 is directly fixed in the mounting groove 101, a cylinder fixing seat 305 of the pressing plate assembly 3, a sliding block mounting seat 302, a gantry lifting main body 401 of the gantry lifting assembly 4 and the hydraulic base 12 are all fixed on the top surface of the whole machine base 1. Through the mounting groove 101, the substrate assembly 2 can be initially positioned, and meanwhile, all components have a stable mounting basis, so that the components are prevented from being displaced due to instability of the base during the welding process, and the welding precision is ensured.

[0024] The substrate assembly 2, also called a comb-shaped substrate assembly, comprises the substrate base 201, a plurality of substrate stand columns 202, stand column guide columns 203, a substrate fixing plate A 204 and a substrate fixing plate B 205.

[0025] ​The pressure plate assembly 3 is used to provide clamping force from the outside of the metal plate 100. It consists of a pressure plate sliding base 301, a slider mounting base 302, a pressure plate cylinder A303, a pressure plate casting 304, a cylinder fixing base 305, a pressure plate drive connecting plate 306, a buffer pad A307, a linear guide rail A308, and a guide slider 309. It is located on both sides of the base plate assembly 2 and multiple sets are arranged to adapt to the width and height of the metal plate 100. The cylinder mounting base 305 and the slider mounting base 302 are fixed on the base 1 of the whole machine. The pressure plate cylinder A303 is fixed on the cylinder mounting base 305. Its piston rod end is connected to the pressure plate sliding base 301 through the pressure plate drive connecting plate 306. The buffer pad A307 is fixed on both sides of the pressure plate drive connecting plate 306. The linear guide rail A308 is fixed on the bottom of the pressure plate sliding base 301 and cooperates with the guide slider 309 on the top of the slider mounting base 302. The pressure plate casting 304 is fixed on the top of the pressure plate sliding base 301 and has a guide hole 310. During operation, the pressure plate cylinder A303 drives the pressure plate sliding base 301 to move along the linear guide rail A308, which in turn drives the pressure plate casting 304 to clamp the metal plate 100 from the outside. The buffer pad A307 can reduce the impact during clamping. The guide hole 310, together with the substrate column 202 and column guide column 203 of the substrate assembly 2, forms a tube 200 insertion and positioning system to ensure that the metal plate 100 is fixed and stable and the tube 200 is inserted accurately.

[0026] The gantry-type lifting assembly 4 is the core structure that drives the lifting of welding-related components. It is arranged in two rows on both sides of the base plate assembly 2, with three sets in each row. Adjacent sets are connected by an electrically controlled fixing bracket 11. It consists of a gantry-type lifting body 401, a vertical ball screw 402, a servo motor mounting base 403, a buffer pad B404, a vertical guide rail 405, a slider-type lifting platform 406, a linear guide rail B407, a pressure plate cylinder B408, and a buffer pressure plate 409. The gantry-type lifting body 401 is fixed to the top of the base 1. The vertical ball screw 402 is rotatably mounted on the gantry-type lifting body 401. The servo motor mounting base 403 is fixed to the top of the gantry-type lifting body 401 for mounting the servo motor. The slider-type lifting platform 406 is connected to the vertical ball screw 402 through a screw nut and slides along the vertical guide rail 405. The buffer pad B404 is fixed to the gantry-type lifting body 401. The linear guide rail B407 is fixed to the slider-type lifting platform 406. The pressure plate cylinder B408 is fixed to both sides of the bottom of the slider-type lifting platform 406. The buffer pressure plate 409 is connected to the piston rod end of the pressure plate cylinder B408. A servo motor drives a vertical ball screw 402 to rotate, which in turn drives a slider-type lifting platform 406 to rise and fall along a vertical guide rail 405. A buffer pad B404 limits the lifting range of the slider-type lifting platform 406 and reduces impact. A linear guide rail B407 provides a translation track for the welding gun assembly 14 and the material pushing mechanism 5. A pressure plate cylinder B408 drives a buffer pressure plate 409 to assist in fixing components, thereby achieving precise lifting and position adjustment of welding-related components.

[0027] The welding torch assembly 14 is used for the initial welding positioning of the pipe 200 and the metal plate 100, and operates using resistance welding. It is mounted on the sliding lifting platform 406 of the three sets of gantry-type lifting assemblies 4 in a row, and is connected to the linear guide rail B407 on the sliding lifting platform 406 via a motor moving module. When the gantry-type lifting assembly 4 raises the sliding lifting platform 406 to a suitable height, the motor moving module drives the welding torch assembly 14 to move along the linear guide rail B407, aligning it with the connection points of the pipe 200 and the metal plate 100 at different positions. Resistance welding is then used to initially fix the pipe 200 onto the two metal plates 100, providing a stable foundation for subsequent welding and preventing the pipe 200 from shifting during subsequent operations.

[0028] The function of the pushing mechanism 5 is to push the pipe 200 into the insertion hole of the metal plate 100. It is installed on the slider lifting platform 406 of the three sets of gantry lifting components 4 in another row. It is connected to the linear guide rail B407 through the motor moving module. It consists of a moving platform 501, a pipe inlet groove 502 and an electric push rod 503. In terms of connection, the moving platform 501 is connected to the motor moving module, the pipe inlet groove 502 is fixed on the moving platform 501, and the electric push rod 503 is fixed on the pipe inlet groove 502. During operation, the gantry lifting assembly 4 drives the pushing mechanism 5 to rise and fall, and the motor moving module drives the moving platform 501 to move horizontally along the linear guide rail B407, so that the pipe inlet 502 is aligned with the discharge port of the feeding mechanism 6 to receive the pipe 200. Then the electric push rod 503 moves to push the pipe 200 in the pipe inlet 502 into the insertion hole of the metal plate 100, realizing the automatic pushing of the pipe 200, ensuring accurate pushing position and high efficiency.

[0029] The feeding mechanism 6 is used to feed the pipe 200 to the pushing mechanism 5. It is located above the pushing mechanism 5 and fixed on the slider lifting platform 406 of the gantry lifting assembly 4. The positional relationship between the feeding mechanism 6 and the pushing mechanism 5 is such that the discharge port of the feeding mechanism 6 is directly opposite the pipe inlet of the pipe inlet groove 502 of the pushing mechanism 5. During operation, the feeding mechanism 6 feeds the pipe 200 into the pipe inlet groove 502 in an orderly manner, providing the pushing mechanism 5 with the pipe 200 to be pushed, realizing the automatic feeding of the pipe 200, avoiding the problems of low efficiency and inaccurate positioning of manual feeding, and ensuring the continuity of the entire welding process.

[0030] The feeding box girder assembly 7 is a structure for installing and driving the metal plate 100 to be welded to move horizontally or vertically. It works in conjunction with the box girder column assembly 9, the digital cylinder 10, and the traveling positioning beam 8. The feeding box girder assembly 7 moves up and down along the three sets of box girder column assemblies 9. The digital cylinders 10, fixed on the box girder column assemblies 9 on both sides, are connected to the feeding box girder assembly 7. The traveling positioning beam 8 is located on the feeding box girder assembly 7 and can move along it. The digital cylinders 10 drive the feeding box girder assembly 7 to move up and down along the box girder column assemblies 9, and the traveling positioning beam 8 drives the metal plate 100 to move horizontally on the feeding box girder assembly 7, thereby realizing the lifting, lowering, and horizontal adjustment of the metal plate 100. This facilitates the precise delivery of the metal plate 100 to the welding position and the removal of the finished product after welding.

[0031] The traveling positioning beam 8 is used to install and precisely position the metal plate 100 to be welded. It consists of a sliding positioning beam 801, several traveling trolleys 802, a rotary clamping cylinder 803, a pressing plate 804, and inserts 805. Several traveling trolleys 802 are arranged at equal intervals and fixed on the sliding positioning beam 801 and cooperate with the feed box beam assembly 7. The rotary clamping cylinder 803 is located on the top of the sliding positioning beam 801, and its piston rod end is connected to the pressing plate 804. The inserts 805 are embedded in the bottom of the sliding positioning beam 801 and are aligned and inserted with the column guide post 203 of the base plate assembly 2. When installing the metal plate 100, the rotary clamping cylinder 803 drives the pressing plate 804 to clamp the metal plate 100 from both sides. The traveling trolley 802 drives the sliding positioning beam 801 to move along the feeding box beam assembly 7. The insert 805 and the column guide column 203 are inserted to achieve precise positioning of the metal plate 100 and the base plate assembly 2. After welding, it can also drive the finished product to move away with the feeding box beam assembly 7, ensuring that the metal plate 100 is installed stably, positioned accurately, and the finished product is transported conveniently.

[0032] The box girder column assembly 9 provides lifting guidance and support for the feeding box girder assembly 7. Three sets are provided, each fixed to a corresponding hydraulic base 12. The box girder column assembly 9 is fixed to the hydraulic base 12, and the feeding box girder assembly 7 is fitted onto it and can slide along it. Digital cylinders 10 are fixed to the box girder column assemblies 9 on both sides. Simultaneously, the two sets of box girder column assemblies 9 on both sides of the machine base 1 are connected to the gantry-type lifting assembly 4 via gantry frame connecting fixing seats 13. This design provides stable guidance for the lifting of the feeding box girder assembly 7, ensuring smooth lifting; and enhances the overall structural stability of the equipment by connecting it to the gantry-type lifting assembly 4 via the gantry frame connecting fixing seats 13, preventing component shaking during welding from affecting accuracy.

[0033] The digital cylinder 10 is the power component that drives the feeding box girder assembly 7 to rise and fall. It is fixed to the two box girder column assemblies 9 on both sides, and its output end is connected to the feeding box girder assembly 7. During operation, the extension and retraction of the digital cylinder 10 drives the feeding box girder assembly 7 to rise and fall along the box girder column assemblies 9, thereby driving the traveling positioning beam 8 and the metal plate 100 or finished product to rise and fall. Compared with traditional drive methods, the digital cylinder 10 can achieve precise lifting and falling control, ensuring that the lifting and falling position of the feeding box girder assembly 7 is accurate and meets the height requirements for positioning the metal plate 100 and lifting the finished product away.

[0034] The electrically controlled fixing bracket 11 is used to connect adjacent gantry lifting assemblies 4, fixing the three sets of gantry lifting assemblies 4 in each row together in series. This design allows the gantry lifting assemblies 4 in the same row to form a whole, avoiding the deviation or shaking of a single gantry lifting assembly 4 during the lifting process, ensuring that the three sets of gantry lifting assemblies 4 move synchronously, thereby ensuring the consistency of the lifting and translation of the welding torch assembly 14 or the pusher mechanism 5, and improving the welding accuracy.

[0035] The hydraulic base 12 serves as the mounting foundation for the box girder column assembly 9. Three bases are provided, each corresponding to one of the three sets of box girder column assemblies 9. Simultaneously, the hydraulic base 12 is fixed to the machine base 1. It provides stable support for the box girder column assembly 9, preventing it from tilting due to uneven stress. Furthermore, its fixation to the machine base 1 enhances the overall stability of the equipment, ensuring the smooth lifting and lowering of the feeding box girder assembly 7.

[0036] The gantry frame connecting and fixing seat 13 is used to connect the box girder column assembly 9 and the gantry lifting assembly 4. It fixes the two sets of box girder column assemblies 9 on both sides of the machine base 1 together with the corresponding gantry lifting assemblies 4. This structure allows the box girder column assembly 9 and the gantry lifting assembly 4 to form a mutually supporting whole, reducing the relative swaying between the two during operation. This ensures that when the gantry lifting assembly 4 drives the welding gun assembly 14 and the material pushing mechanism 5 to rise and fall, it maintains a relatively stable positional relationship with the feeding box girder assembly 7 on the box girder column assembly 9, avoiding the impact of component swaying on the pushing of the pipe 200 and the welding accuracy.

[0037] Metal plate 100 is the base plate for welding and needs to cooperate with multiple components. It is installed on the sliding positioning beam 801 of the walking positioning beam 8 and is clamped and fixed by a rotating clamping cylinder 803 and a pressing plate 804. Two metal plates 100 are located on both sides of the base plate assembly 2. The base plate column 202 of the base plate assembly 2 is inserted into the gap between the two metal plates 100. The pressing plate assembly 3 clamps the metal plate 100 from the outside. The pipe 200 is inserted into the insertion hole of the metal plate 100 and welded and fixed by the welding gun assembly 14. As the installation carrier of the pipe 200, the stability of the metal plate 100 and the accuracy of its positioning directly affect the welding quality of the pipe 200. Through the cooperation of multiple components for fixing and positioning, it can be ensured that the metal plate 100 does not shift during the welding process, thus ensuring welding accuracy.

[0038] The tube 200 is a component welded to the metal plate 100. It is fed into the tube inlet slot 502 of the pusher mechanism 5 by the feeding mechanism 6, and then pushed into the insertion hole of the metal plate 100 by the electric push rod 503. Subsequently, it is initially fixed to the two metal plates 100 by resistance welding by the welding gun assembly 14. The base plate posts 202 of the base plate assembly 2 space the adjacent tubes 200. The pushing and welding process of the tubes 200 is completed by automated components. Compared with manual operation, it can ensure that the tubes 200 are inserted accurately and welded firmly. The spacing of the base plate posts 202 can avoid mutual interference between the tubes 200, ensuring that each tube 200 is accurately welded.

[0039] From the overall operation flow, firstly, the rotating clamping cylinder 803 of the traveling positioning beam 8 clamps and fixes the two metal plates 100 onto the sliding positioning beam 801. The traveling trolley 802 drives the metal plates 100 to move horizontally along the feeding box beam assembly 7. At the same time, the digital cylinder 10 drives the feeding box beam assembly 7 to rise and fall along the box beam column assembly 9, so that the insert 805 at the bottom of the sliding positioning beam 801 is aligned and inserted with the column guide post 203 of the base plate assembly 2, achieving the initial positioning of the metal plates 100. The purpose of this step is to accurately transport the metal plates 100 to the initial welding position through the coordination of multiple components, preparing for the subsequent insertion and welding of the pipes 200.

[0040] After the metal plate 100 is initially positioned, the pressure plate cylinder A303 of the pressure plate assembly 3 is activated, driving the pressure plate sliding base 301 to move along the linear guide rail A308, causing the pressure plate casting 304 to clamp from the outside of the metal plate 100. At this time, the guide hole 310 of the pressure plate casting 304 is aligned with the substrate pillar 202 and pillar guide pillar 203 of the substrate assembly 2, forming a tube 200 insertion positioning channel. This step can further fix the metal plate 100 and at the same time construct a precise tube 200 insertion path, avoiding deviations during subsequent tube 200 pushing.

[0041] Next, the feeding mechanism 6 places the pipe 200 into the inlet slot 502 of the pushing mechanism 5. The servo motor of the gantry lifting assembly 4 drives the vertical ball screw 402 to rotate, causing the slider lifting platform 406 to rise and fall along the vertical guide rail 405. At the same time, the motor moving module drives the pushing mechanism 5 to translate along the linear guide rail B407, so that the inlet slot 502 is aligned with the insertion hole of the metal plate 100. Then, the electric push rod 503 pushes the pipe 200 into the insertion hole. This process realizes automatic feeding, precise alignment and pushing of the pipe 200 without manual intervention, improving welding efficiency and pushing accuracy.

[0042] After the pipe 200 is pushed into the insertion hole of the metal plate 100, the gantry lifting assembly 4, which is equipped with the welding gun assembly 14, moves and moves the welding gun assembly 14 up, down and horizontally, so that the welding gun is aligned with the connection point between the pipe 200 and the metal plate 100, and the pipe 200 is initially welded and fixed by resistance welding. During the initial welding and feeding process, the pressure plate cylinder B408 pushes the buffer pressure plate 409 through the guide hole to perform secondary clamping and positioning of the metal plate. After all the pipes 200 are welded, the clamping structure of the pressure plate assembly 3 and the traveling positioning beam 8 is released. The digital cylinder 10 drives the feeding box beam assembly 7 to rise, and the traveling positioning beam 8 moves the finished product horizontally along the feeding box beam assembly 7 and leaves the equipment. This step completes the welding of the pipes 200 and the metal plate 100 and the delivery of the finished product. The whole process is highly automated, and the cooperation of various components ensures the welding quality and the convenience of finished product delivery.
