Description

Technical Field

[0001] This invention relates to the field of welding equipment technology, and in particular to a track-moving multi-angle rotating welding device. Background Technology

[0002] Welding, also known as fusion welding or melting, is a manufacturing process and technology that joins metals or other thermoplastic materials such as plastics by heating, high temperature or high pressure. Welding achieves the purpose of joining through three methods: fusion welding, pressure welding and brazing. Welding equipment is the equipment required to realize the welding process. Welding equipment includes welding machines, welding process equipment and welding auxiliary tools. Various metal parts generally need to be welded during processing.

[0003] Existing welding equipment generates welding slag during the welding process. The welding slag accumulates on the welding table and the parts. If the welding slag is not cleaned in time, it will affect the welding quality of the parts. Generally, manual cleaning is used to deal with the welding slag. However, because the welding head is at a high temperature, manual cleaning is dangerous, slow, and ineffective. Summary of the Invention

[0004] This invention discloses a track-moving multi-angle rotating welding device, which aims to solve the technical problems of welding slag accumulation on the welding table and parts, which affects the welding quality of the parts, and the use of manual cleaning to deal with welding slag, which is dangerous, slow and ineffective.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A track-moving multi-angle rotating welding device includes a welding table track, which is longitudinally arranged, and a welding arm track is transversely arranged on the side of the welding table track. A slide block is slidably arranged on the welding table track, and a support platform is fixedly connected to the top surface of the slide block. A servo motor is fixedly connected to one outer wall of the support platform. The power output shaft of the servo motor is driven to a longitudinal bogie via a coupling. A second servo motor is fixedly connected to the middle of the bottom surface of the longitudinal bogie. The power output shaft of the second servo motor is driven to a horizontal turntable via a coupling. A welding table is fixedly connected to the top surface of the horizontal turntable. Mounting frames are fixedly connected to both ends of the outer wall of the welding table. A cleaning component is arranged on the mounting frame, and a protective component is arranged on the welding table.

[0007] The system is equipped with a welding table track, welding arm track, slide block, support platform, servo motor one, longitudinal bogie, servo motor two, horizontal turntable, welding table, mounting frame, cleaning components, and protective components. Adjusting the protective components prevents welding slag from splattering due to various factors during welding. The slide block moves the workpiece along the welding table track, and the welding arm moves along the welding arm track. Adjusting servo motor one allows the workpiece to rotate 180° longitudinally, and adjusting servo motor two allows it to rotate 360° horizontally, ensuring the workpiece and welding head are at the optimal angle for welding, thus improving welding quality. The cleaning components remove welding slag adhering to the workpiece and welding table, achieving automatic slag removal, preventing slag accumulation, eliminating the need for manual operation, saving time and effort, ensuring high safety, and providing high slag removal efficiency.

[0008] In a preferred embodiment, the cleaning assembly includes a drive motor 1, which is fixedly mounted on the outer wall of one of the mounting brackets. The power output shaft of the drive motor 1 is connected to a lead screw via a coupling. A movable seat 2 is threaded onto the surface of the lead screw. Two movable seats 1 are threaded onto the surface of the lead screw, symmetrically arranged about the movable seats 2. Guide rods are fixedly connected to the outer walls of the two mounting brackets on their adjacent sides. Both movable seats 1 and 2 are slidably mounted on the surface of the guide rods. The drive motor 2 is fixedly mounted on the outer wall of the movable seat 1 away from the lead screw. The power output shaft of the drive motor 2 is connected to a rotating seat via a coupling.

The power output shaft of the drive motor three is connected to a rotating disk via a coupling. An eccentric rod is fixedly connected to one end of the top surface of the rotating disk, and a steering plate is rotatably mounted on the surface of the eccentric rod. A connecting frame two is fixedly connected to the outer wall of the movable base two at the side away from the lead screw. A guide frame is fixedly connected to the outer wall of the connecting frame two at the side away from the lead screw. A positioning seat is slidably positioned inside the guide frame. A connecting rod is fixedly connected to the top surface of the positioning seat.

A fan is fixedly mounted on the inner wall of the air inlet seat, and an air outlet pipe is fixedly connected to the outer wall of the air inlet seat. The air outlet pipe is located on the side of the output end of the fan and faces the welding table.

[0009] With the cleaning components in place, during welding gaps, drive motor one is started, and drive motor two is adjusted to make the cleaning claws contact the outer wall of the weldment. The cleaning claws move along the surface of the weldment to scrape off the welding slag adhering to the weldment. Drive motor three is started to make the air duct reciprocate along the top of the welding table to blow away the welding slag on the weldment and the welding table, thus achieving rapid cleaning of the welding slag.

[0010] In a preferred embodiment, both side walls of the welding station are fixedly connected to horizontally arranged protective plates 1, and both ends of the top surface of the welding station are provided with longitudinally arranged slag discharge ports. The protective assembly includes two protective plates 2 symmetrically arranged about the welding station, with the two protective plates 1 and 2 arranged in a U-shape. Connecting frames 3 are fixedly connected to both ends of the outer walls of the two protective plates 2 that are close to each other. Fixed plates are fixedly connected to the inner walls of both sides of the slag discharge ports. The connecting frames 3 are movably arranged on the outer walls of the two fixed plates that are close to each other. A guide groove is provided inside the fixed plate, consisting of a vertical groove and an arc-shaped inclined groove. The bottom of the arc-shaped inclined groove is connected to the middle of the vertical groove. A positioning rod 1 is slidably arranged inside the vertical groove, and positioning rods 2 are slidably arranged inside the vertical groove and the arc-shaped inclined groove. Both positioning rods 1 and 2 are fixedly connected to the connecting frames 3. The outer wall of the two connecting frames is fixedly connected to the outer wall of the two connecting frames that are close to each other. The welding table has an installation groove inside.

The linkage gear one and linkage gear two on both sides are meshed with the same synchronous belt. The linkage gear two is rotatably set on the outer wall of one of the fixed plates. The outer wall of the linkage gear two away from the fixed plate is rotatably set with a rotating plate. The end of the rotating plate away from the linkage gear two is rotatably set with a steering plate two. The end of the steering plate two away from the rotating plate is rotatably set on the surface of the connecting rod.

[0011] The system includes a protective plate, a slag discharge port, and protective components. After the workpiece is fixed, the drive motor is activated to move the protective plate upwards and outwards until it rotates to a vertical position. This creates a U-shaped structure between the protective plates, forming a protective structure that prevents slag from splashing everywhere during welding and causing injury to workers. It also facilitates the collection of slag. After welding is completed, the drive motor is reversed to rotate the protective plate to a horizontal position and seal the slag discharge port. The protective plate is now flush with the welding table, making it easy to remove the welded workpiece.

[0012] As can be seen from the above, the track-moving multi-angle rotating welding device provided by the present invention has a protective function. The protective plate one and the protective plate two prevent welding slag from splashing outwards in all directions, realize the automatic treatment of welding slag, avoid welding slag accumulation, improve welding quality, eliminate the need for manual operation, save time and effort, and have high welding slag cleaning efficiency and high safety.

[0021] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0022] The track-moving multi-angle rotating welding device disclosed in this invention is mainly used in scenarios where welding slag accumulates on the welding table and parts, affecting the welding quality of the parts. Manual cleaning of welding slag is dangerous, slow, and ineffective.

[0023] Reference Figures 1-7A multi-angle rotating welding device with track movement includes a welding table track 1, which is longitudinally arranged, and a welding arm track 2 is arranged laterally on the side of the welding table track 1. A slide block 3 is slidably arranged on the welding table track 1. A support platform 4 is fixedly connected to the top surface of the slide block 3. A servo motor 5 is fixedly connected to one side of the outer wall of the support platform 4. The power output shaft of the servo motor 5 is driven to a longitudinal bogie 6 through a coupling. A servo motor 7 is fixedly connected to the middle of the bottom surface of the longitudinal bogie 6. The power output shaft of the servo motor 7 is driven to a horizontal turntable 8 through a coupling. A welding table 9 is fixedly connected to the top surface of the horizontal turntable 8. Mounting brackets 12 are fixedly connected to both ends of the outer wall of the welding table 9. A cleaning component 13 is arranged on the mounting bracket 12. A protective component 14 is arranged on the welding table 9.

[0024] Specifically, before welding, the workpiece to be welded is fixed on the welding table 9, and the protective component 14 is adjusted. During welding, to prevent welding slag from splashing everywhere due to various factors, the workpiece to be welded is moved along the welding table track 1 by the slide block 3, and the welding arm moves along the welding arm track 2. The workpiece to be welded is rotated 180° longitudinally by adjusting the servo motor 5, and rotated 360° horizontally by adjusting the servo motor 7, so that the workpiece to be welded and the welding head are kept at the optimal angle for welding, thus improving the welding quality. The welding slag adhering to the workpiece and the welding table 9 is cleaned by the cleaning component 13, realizing the automatic treatment of welding slag, avoiding welding slag accumulation, improving the welding quality, eliminating the need for manual operation, saving time and effort, and ensuring high safety and high welding slag cleaning efficiency.

[0025] Reference Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5In a preferred embodiment, the cleaning assembly 13 includes a drive motor 1301, which is fixedly mounted on the outer wall of one of the mounting brackets 12. The power output shaft of the drive motor 1301 is connected to a lead screw 1302 via a coupling. A movable seat 1312 is threaded onto the surface of the lead screw 1302. Two movable seats 1303 are threaded onto the surface of the lead screw 1302. The two movable seats 1303 are symmetrically arranged about the movable seats 1312. A guide rod 1324 is fixedly connected to the outer wall of the two mounting brackets 12 on the side closest to each other. Both the movable seats 1303 and the movable seats 1312 are slidably arranged. On the surface of guide rod 1324; a drive motor 1304 is fixedly mounted on the outer wall of the end of movable seat 1303 away from lead screw 1302. The power output shaft of drive motor 1304 is connected to a rotating seat 1305 via a coupling. A rotating seat 1306 is fixedly connected to the outer wall of rotating seat 1305 away from drive motor 1304. A connecting frame 1307 is fixedly connected to the bottom surface of rotating seat 1306. A fixing rod 1308 is fixedly connected to the outer wall of connecting frame 1307 away from rotating seat 1305. Several elastic rods 1309 are fixedly connected to the bottom surface of fixing rod 1308. The bottom surface of elastic rods 1309 is fixedly connected to... There is a mounting base 1310, and a cleaning claw 1311 is fixedly connected to the outer wall of the mounting base 1310. The cleaning claw 1311 is slidably positioned above the welding table 9. A drive motor 1313 is fixedly mounted on the top surface of the end of the movable base 1312 away from the lead screw 1302. The power output shaft of the drive motor 1313 is connected to a rotating disk 1314 via a coupling. An eccentric rod 1315 is fixedly connected to one end of the top surface of the rotating disk 1314. A steering plate 1316 is rotatably mounted on the surface of the eccentric rod 1315. A connecting frame 1317 is fixedly connected to the outer wall of the movable base 1312 on the side away from the lead screw 1302. The connecting frame 1317 is located away from the lead screw 1302. A guide frame 1318 is fixedly connected to one outer wall of the rod 1302. A positioning seat 1319 is slidably arranged inside the guide frame 1318. A connecting rod 1320 is fixedly connected to the top surface of the positioning seat 1319. The end of the steering plate 1316 away from the eccentric rod 1315 is rotatably arranged on the surface of the connecting rod 1320. An air inlet seat 1321 is fixedly connected to both outer walls of the positioning seat 1319. A fan 1322 is fixedly installed on the inner wall of the air inlet seat 1321. An air outlet pipe 1323 is fixedly connected to the outer wall of the air inlet seat 1321. The air outlet pipe 1323 is located on the side of the output end of the fan 1322 and faces the welding table 9.

[0026] Specifically, during the welding gap, the drive motor 1301 is started to rotate the lead screw 1302, causing the moving seats 1303 and 1312 to slide along the surface of the lead screw 1302. The drive motor 1304 is adjusted to rotate the rotating seat 1305, causing the cleaning claw 1311 to change position, so that the cleaning claw 1311 contacts the outer wall of the weldment. The cleaning claw 1311 moves along the surface of the weldment, and with the elastic action of the elastic rod 1309, the adhesive on the weldment is removed. As the welding slag is scraped off, the second movable seat 1312 moves the air outlet 1323. The third drive motor 1313 is started to rotate the rotating disk 1314. The eccentric rod 1315 moves and drives the first steering plate 1316 to rotate. Through the connecting rod 1320, the positioning seat 1319 slides along the inside of the guide frame 1318, so that the air outlet 1323 moves back and forth above the welding table 9, blowing away the welding slag on the workpiece and the welding table 9, thus achieving rapid cleaning of the welding slag.

[0027] Reference Figure 1 , Figure 2 , Figure 6 and Figure 7In a preferred embodiment, both side walls of the welding station 9 are fixedly connected with horizontally arranged protective plates 10, and both ends of the top surface of the welding station 9 are provided with longitudinally arranged slag discharge ports 11. The protective assembly 14 includes two protective plates 1401 symmetrically arranged about the welding station 9, with the two protective plates 10 and 1401 arranged in a U-shape. Both ends of the outer wall of the two protective plates 1401 that are close to each other are fixedly connected with connecting brackets 1403, and both inner walls of the slag discharge ports 11 are fixedly connected with fixing plates 140. 2. Connecting frame three 1403 is movably mounted on the outer wall of one side of the two fixed plates 1402 that are close to each other. The fixed plate 1402 has a guide groove 1404 inside, which consists of a vertical groove and an arc-shaped inclined groove. The bottom of the arc-shaped inclined groove is connected to the middle of the vertical groove. A positioning rod one 1405 is slidably mounted inside the vertical groove, and a positioning rod two 1406 is slidably mounted inside both the vertical groove and the arc-shaped inclined groove. Both positioning rod one 1405 and positioning rod two 1406 are fixedly connected to the outer wall of connecting frame three 1403. The two connecting frames three 1403... A connecting rod 1407 is fixedly connected to the outer wall of the two adjacent sides; the welding table 9 has an installation groove inside, and a drive motor 1408 is fixedly installed in the middle of the inner wall of the installation groove. The power output shaft of the drive motor 1408 is connected to a drive gear 1409 through a coupling. Two symmetrically arranged driven gears 1410 mesh on the surface of the drive gear 1409. A linkage gear 1411 is fixedly connected to the outer wall of the driven gear 1410. A linkage gear 2 is provided on the side of the two linkage gears 1411 that are far apart from each other. 412, the first linkage gear 1411 and the second linkage gear 1412 on both sides are meshed with the same synchronous belt 1413. The second linkage gear 1412 is rotatably mounted on the outer wall of one of the fixed plates 1402. A rotating plate 1414 is rotatably mounted on the outer wall of the side of the second linkage gear 1412 away from the fixed plate 1402. A second steering plate 1415 is rotatably mounted on the end of the rotating plate 1414 away from the second linkage gear 1412. The end of the second steering plate 1415 away from the rotating plate 1414 is rotatably mounted on the surface of the connecting rod 1407.

[0028] Specifically, after the workpiece is fixed, the drive motor 1408 is started to rotate the drive gear 1409. The drive gear 1409 meshes with the two driven gears 1410, causing the driven gears 1410 to drive the linkage gear 1411 to rotate. Both linkage gear 1411 and linkage gear 2 1412 mesh with the synchronous belt 1413, causing the rotating plate 1414 to rotate, which in turn causes the steering plate 2 1415 to rotate. This causes the positioning rod 2 1406 to slide along the vertical groove into the arc-shaped inclined groove, and the positioning rod 1 1405 to slide upward along the vertical groove. The protective plate 1401 moves upward and then unfolds outward until it rotates to a vertical position, forming a U-shaped structure with the protective plate 10 and the protective plate 1401. This creates a protective structure to prevent welding slag from splashing everywhere and injuring workers during welding, while also facilitating the collection of welding slag. After welding is completed, the drive motor 1408 is reversed to rotate the protective plate 1401 to a horizontal position and seal the slag discharge port 11. The protective plate 1401 is then flush with the welding table 9, making it easy to remove the welded workpiece.

[0029] Working principle: Before welding, the workpiece to be welded is fixed on the welding table 9. After the workpiece is fixed, the drive motor 1408 is started to rotate the drive gear 1409. The drive gear 1409 meshes with the two driven gears 1410, causing the driven gears 1410 to drive the linkage gear 1411 to rotate. Both linkage gear 1411 and linkage gear 1412 mesh with the synchronous belt 1413, causing the rotating plate 1414 to rotate, which in turn causes the steering plate 1415 to rotate. This causes the positioning rod 1406 to slide along the vertical groove into the arc-shaped inclined groove. The positioning rod 1405 then slides upward along the vertical groove, causing the protective plate 1401 to move upward. The protective plate 10 is extended outwards until it rotates to a vertical position, forming a U-shaped structure with the protective plate 10, thus creating a protective structure to prevent welding slag from splashing everywhere and injuring workers during welding. This also facilitates slag collection. The slide block 3 moves the workpiece to be welded along the welding table track 1, and the welding arm moves along the welding arm track 2. The servo motor 5 is adjusted to rotate the workpiece 180° longitudinally, and the servo motor 7 is adjusted to rotate the workpiece 360° horizontally, ensuring the workpiece and welding head are at the optimal angle for welding, improving welding quality and reducing welding friction. During the interval, drive motor 1301 is started to rotate the lead screw 1302, causing the moving seat 1303 and moving seat 2 1312 to slide along the surface of the lead screw 1302. Drive motor 2 1304 is adjusted to rotate the rotating seat 1305, causing the cleaning claw 1311 to change position and contact the outer wall of the weldment. The cleaning claw 1311 moves along the surface of the weldment, and with the elastic action of the elastic rod 1309, the welding slag adhering to the weldment is scraped off. Moving seat 2 1312 then moves the air outlet pipe 1323. Drive motor 3 1313 is started to rotate the rotating disk 1314, and the eccentric rod 1315 moves accordingly. The steering plate 1316 is rotated, and the positioning seat 1319 slides along the inside of the guide frame 1318 through the connecting rod 1320. This causes the air outlet pipe 1323 to reciprocate above the welding table 9, blowing away the welding slag on the workpiece and the welding table 9. This achieves rapid cleaning of the welding slag, avoids slag accumulation, improves welding quality, eliminates the need for manual operation, saves time and effort, and ensures high safety and high efficiency in cleaning welding slag. After welding is completed, the drive motor 1408 is reversed to rotate the protective plate 1401 to a horizontal position and seal the slag discharge port 11. The protective plate 1401 is flush with the welding table 9, making it easy to remove the welded workpiece.
