Description

Technical Field

[0001] The invention relates to the technical field of welding equipment, and in particular to a robot workstation alternating welding device suitable for a large-span cable tray. Background Art

[0002] With the rapid development of industries such as power engineering and industrial construction, large-span cable trays are being used more and more widely. Large-span cable trays are usually made up of multiple cable tray segments. The welding workload is huge and there are strict requirements on welding quality and efficiency.

[0003] In the past, when welding cable trays, most of them used traditional welding methods, which are often highly dependent on manual work. Specifically, welders need to hold welding tools and perform welding work one by one along the welds of the cable tray. However, this traditional manual welding mode has many disadvantages. In terms of labor intensity, welders hold welding tools for a long time to perform repetitive and meticulous welding operations, which can easily cause fatigue and great labor intensity. Secondly, in terms of welding efficiency, the speed of manual welding of welds one by one is relatively slow, and it is impossible to complete a large number of welding tasks in a short time, which makes the efficiency of the entire welding work at a low level, and it is difficult to meet the needs of large-scale production and rapid construction.

[0004] More importantly, due to the inevitable instability of manual operation itself, it is difficult to ensure that the welding quality can always remain consistent. During the welding process, factors such as slight shaking of the welder's hands, slight deviations in operating angles and strength may cause uneven welds, such as different weld widths and heights. Moreover, these unstable factors can easily cause various welding defects, such as porosity, slag inclusions, incomplete penetration, etc., which will adversely affect the overall quality and subsequent performance of the cable tray and pose a safety hazard.

The micro motor 26 is powered on to drive the second gear 261 to rotate. Through the meshing transmission with the transmission gear 251, the annular plate 27 and the annular groove 231 are cooperated, so that the linkage disk 271 drives the linkage mechanism 3 and related components to make a circular motion to adjust the orientation. The external motor 34 is powered on to drive the threaded rod 321 to rotate. The threaded transmission with the threaded hole 412 and the cooperation of the second slide column 33 and the sliding groove 411 drive the lateral adjustment. The joint mechanism 4 and the welding mechanism 5 move laterally, and then the joints of the automated robotic arm 54 cooperate to make the laser welding head 55 contact the welding position to complete the welding. During the process, the self-locking motor 52 is energized to drive the disc 53 to rotate and adjust the direction of the automated robotic arm 54. The two sets of fixed mechanisms 1 of the equipment are arranged opposite to each other. When adjusting the adjustment plate 44 and the top welding mechanism 5, the two sets of linkage mechanisms 3 are first made parallel, and the two external motors 34 drive the lateral adjustment mechanism 4 to move and adjust the position, and then the two sets of lateral adjustment mechanisms 4 are aligned and the two sets of moving grooves 413 correspond. Then the micro cylinder 421 is energized to push the adjustment plate 44 to move, and the moving block 43 is swapped between the moving grooves 413 to achieve adjustment, and this adjustment can expand the welding area.

[0046] Embodiment 2, according to Figure 1-Figure 2 , Figure 5 as well as Figure 7-Figure 9 As shown, the lateral adjustment mechanism 4 includes two moving seats 41;

[0047] The bottom of the two moving seats 41 is provided with a sliding groove 411, one side of the outer wall of the two moving seats 41 is provided with a threaded hole 412, the top of the two moving seats 41 is provided with a group of moving grooves 413, the top of the two moving seats 41 is provided with a fixing groove 414, one side of the outer wall of the two moving seats 41 is fixedly installed with a side plate 42, the inside of the two side plates 42 is fixedly inserted with a micro cylinder 421, a moving block 43 is slidably embedded between the inner surface walls of the two groups of moving grooves 413, an adjusting plate 44 is fixedly installed between the tops of a group of moving blocks 43, and the telescopic ends of the two micro cylinders 421 are respectively Contacting one side of the outer wall of the two adjustment plates 44, the top of the adjustment plate 44 is provided with two engaging grooves 441, the inside of the two fixed grooves 414 are fixedly inserted with electric telescopic rods 45, the top of the telescopic ends of the two electric telescopic rods 45 are fixedly installed with engaging blocks 451, and the outer walls of the engaging blocks 451 are respectively engaged and limited in the inside of the engaging grooves 441, the top center of the two movable seats 41 are fixedly installed with conductive contact components 415, the bottom center of the adjustment plate 44 is fixedly installed with a conductive column 442, and the top of the conductive contact component 415 is electrically connected to the bottom of the conductive column 442;

[0049] In this embodiment, the device arranges two sets of fixing mechanisms 1 in an opposing manner. When it is necessary to move the adjustment plate 44 and the welding mechanism 5 on the top thereof, it is necessary to first ensure that the two sets of linkage mechanisms 3 are in a parallel state. Then, when the two external motors 34 are powered on, their output ends drive the two threaded rods 321 to drive the lateral adjustment mechanism 4 to move back and forth through threaded rotation to adjust their own positions.

[0050] Embodiment 3, according to Figure 1-Figure 6As shown, the rotating mechanism 2 includes two fixed disks 21, a group of slide seats 22 are fixedly installed at the bottom of the two fixed disks 21, annular beams 23 are fixedly installed at the tops of the two fixed disks 21, annular grooves 231 are opened at the tops of the two annular beams 23, built-in motors 24 are fixedly inserted inside the two fixed disks 21, and the rotating ends of the two built-in motors 24 are fixedly installed with first gears 241, bearing seats 25 are fixedly installed on the tops of the two fixed disks 21, and the interiors of the two bearing seats 25 are rotatably connected with transmission gears 251, micro motors 26 are fixedly installed on the tops of the two fixed disks 21, and the rotating ends of the two micro motors 26 are fixedly connected with second gears 261, and the outer walls of the second gears 261 are respectively meshed with the inside of the transmission gears 251 for transmission, and a group of annular plates 27 are slidably embedded in the inner walls of the two annular grooves 231, and a linkage disk 271 is fixedly installed between the tops of the two groups of annular plates 27, and the bottom of the linkage disk 271 is fixedly connected to the top of the transmission gear 251;

[0051] The linkage mechanism 3 includes two mounting seats 31, and the tops of the two linkage plates 271 are fixedly installed with the bottoms of the two mounting seats 31 respectively, and a group of bearing bodies 32 are fixedly connected to the tops of the two mounting seats 31, and threaded rods 321 are fixedly connected between the inner surface walls of the two groups of bearing bodies 32, and the two threaded rods 321 are respectively threadedly connected to the inside of the threaded holes 412, and the tops of the two mounting seats 31 are fixedly installed with second slide posts 33, and the outer surfaces of the two second slide posts 33 are respectively slidably embedded in the inside of the sliding groove 411, and one side of the outer wall of the two threaded rods 321 is fixedly installed with an external motor 34, and the bottom of the external motor 34 is fixedly installed with the top of the mounting seat 31;

[0052] The fixing mechanism 1 includes two mounting and fixing frames 11, a group of first slide columns 12 are fixedly installed on the top of the two mounting and fixing frames 11, and two groups of slide seats 22 are respectively slidably embedded between the outer walls of the two groups of first slide columns 12, a tooth plate 13 is fixedly installed on one side of the inner wall of one of the two mounting and fixing frames 11, and the outer walls of the two first gears 241 are respectively meshed and transmitted inside the tooth plate 13.

[0053] In this embodiment, two fixing mechanisms 1 are respectively placed on designated sites. When the device is put into use, the operation process is as follows:

[0054] First, start the built-in motor 24. When powered on, the built-in motor 24 can drive the first gear 241 at its rotating end to rotate at a corresponding frequency. Since the first gear 241 is in meshing connection with the inside of the toothed plate 13, and the toothed plate 13 itself is in a fixed state, and the two slide seats 22 are slidably embedded in the outer wall of the first slide column 12 to cooperate with it, under the synergistic effect between each other, the rotating mechanism 2 and the components fixed thereto can be driven to adjust the longitudinal position. At the same time, after power is turned on, the micro motor 26 will drive the second gear 261 to perform an effective rotation movement, and the second gear 261 and the transmission gear 251 transmit power through meshing transmission, and the linkage disk 271 is fixed on the top of the transmission gear 251. Under the cooperation of a group of annular plates 27 slidably embedded in the annular groove 231, the direction of the related components fixed on the top of the linkage disk 271 can be adjusted. When the linkage disk 271 is based on the transmission gear 251, the rotation of the gear 261 is controlled by the gear 261. When the point rotates, ensure that the linkage mechanism 3 and the components fixed thereto make circular motion, thereby further adjusting their own orientation. In this process, when the external motor 34 is powered on, its output end can drive the threaded rod 321 to rotate inside the two bearing bodies 32. When the threaded rod 321 rotates, it will generate threaded transmission with the inside of the threaded hole 412, and with the cooperation of the second slide column 33 limited in the sliding groove 411, it can drive the lateral adjustment mechanism 4 and the welding mechanism 5 installed on the top to move laterally on the top of the linkage mechanism 3, so as to adjust its own lateral position. When the positions of various components are adjusted, through the mutual cooperation between the various joints of the automated robotic arm 54, the front end laser welding head 55 can be brought into contact with the position to be welded, thereby generating a laser beam and completing the welding process. In this process, the internal self-locking motor 52 will also drive the disc 53 to rotate after being powered on, thereby realizing the directional adjustment of the automated robotic arm 54.

[0055] The working principle of the whole mechanism is as follows: the two fixing mechanisms 1 are respectively designated at the sites, and then when the device is used, the built-in motor 24 is first started. When the built-in motor 24 is powered on, it can drive the first gear 241 at its rotating end to rotate at the same frequency, because the first gear 241 is meshed and connected inside the toothed plate 13, and under the cooperation of the two slide seats 22 slidably embedded in the outer wall of the first slide column 12, it can drive the rotating mechanism 2 and the components fixed thereto to adjust the longitudinal position;

[0056] At the same time, when the micro motor 26 is powered on, it can drive the second gear 261 to rotate effectively, and the second gear 261 and the transmission gear 251 are meshed and transmitted with each other, and the linkage disk 271 is fixed to the top of the transmission gear 251. With the cooperation of a group of annular plates 27 slidingly embedded in the annular groove 231, the components fixed on the top of the linkage disk 271 can be adjusted in one direction. When the linkage disk 271 rotates with the transmission gear 251 as the base point, the linkage mechanism 3 and the components fixed thereto are effectively kept to make circular motion, and their own orientation is further adjusted. In this process, when the external motor 34 is powered on, its output end can drive the threaded rod 321 on two axes. The inside of the bearing body 32 rotates by itself, and when the threaded rod 321 is in the process of self-rotation, it can generate threaded transmission with the inside of the threaded hole 412, and with the cooperation of the second slide column 33 being limited in the sliding groove 411, it can drive the lateral adjustment mechanism 4 and the top-mounted welding mechanism 5 to move laterally on the top of the linkage mechanism 3, and adjust its own lateral position movement. After its own position is adjusted, through the cooperation of various joints of the automatic mechanical arm 54, the front end laser welding head 55 is brought into contact with the position to be welded, and a laser beam is generated to complete the welding process. In this process, the internal self-locking motor 52 is energized to drive the disc 53 to rotate, thereby adjusting the direction of the automatic mechanical arm 54;

[0057] The device sets two sets of fixing mechanisms 1 opposite to each other, and needs to move the adjustment plate 44 and its top welding mechanism 5. First, keep the two sets of linkage mechanisms 3 in a parallel state, and the two external motors 34 are powered on, and their output ends drive the two threaded rods 321 to rotate and drive the lateral adjustment mechanism 4 to move back and forth to adjust its own position, and then keep the two sets of lateral adjustment mechanisms 4 in an aligned state, and the two sets of moving grooves 413 are also corresponding. Then, when the micro cylinder 421 on one side is powered on, its output end generates elasticity, pushes the adjustment plate 44 to move to one side, and moves the moving block 43 from one set of moving grooves 413 to the other set. The inner surface wall of the movable groove 413 is adjusted to realize the adjustment of the adjustment plate 44 and the welding mechanism 5 installed on the top thereof. Such adjustment can better expand the welding area. Finally, when the adjustment plate 44 is moved to the top of another movable seat 41, the adjustment plate 44 and the movable seat 41 are in a completely aligned state, and the conductive column 442 and the conductive contact component 415 are in contact and energized, and the electricity is connected to the electric telescopic rod 45, generating telescopicity to push the locking block 451 to move upward, and the locking block 451 can be firmly stuck in the locking groove 441, thereby maintaining the stability between the adjustment plate 44 and the movable seat 41.
