Description

Technical Field

[0001] The present invention relates to the technical field of laser welding, and in particular to a cold-rolled steel plate laser welding processing system and method. Background Art

[0002] Centrifugal fans are widely used in industrial production, particularly in ventilation, exhaust, cooling, and heating systems. A centrifugal fan impeller typically consists of multiple blades and two front and rear discs. These components operate at high speeds, subjecting them to significant centrifugal forces and aerodynamic loads. The quality of their welding directly impacts the fan's performance and service life, and high-strength welding is often required between the blades and the front and rear discs.

[0003] When welding between the blades and the front and rear discs, due to the large number of blades that need to be welded and their special shapes, it is often only possible to effectively clamp the front and rear discs. Support blades must be installed manually in sequence, and then the joints between the blades and the front and rear discs must be welded in sequence. The inclination angle of the blades determines the flow path and flow rate of the airflow, which is a key factor affecting the efficiency of the fan. Manually installed support welding may result in inconsistent inclination angles of multiple blades. The welding efficiency and quality between the blades and the front and rear discs need to be improved. Summary of the Invention

[0046] See Figure 1 and Figure 4 The second wheel clamping part 43 includes a dual-axis motor 431 installed on the inner wall of the rectangular through hole 42 through a motor seat, and the front and rear output shafts of the dual-axis motor 431 are respectively fixedly connected with a second screw 432, and the front and rear rectangular slides 41 are both slidably installed with support vertical plates 433, and the front and rear two screws 432 are respectively threadedly connected to the corresponding support vertical plates 433, and the upper ends of the front and rear support vertical plates 433 are symmetrically installed with clamping plates 434, and the opposite sides of the inner walls of the bottom ends of the front and rear rectangular slides 41 are respectively installed with left and right bearing seats 435, and the opposite ends of the front and rear two screws 432 are respectively rotatably connected to the corresponding bearing seats 435, and a limiting slide rod 436 that slides through the corresponding support vertical plate 433 is installed on the left side of the inner wall of the rectangular slide 41, and the end of the limiting slide rod 436 away from the corresponding support vertical plate 433 is fixedly connected to the corresponding bearing seat 435.

[0047] First, the incomplete gear 1 542 is controlled to rotate intermittently by the No. 1 motor 541, and the incomplete gear 1 542 is transmitted with the transmission gear 536 to drive the circular column 52 to rotate intermittently. During this period, multiple storage troughs 531 will be connected with the rectangular feed port 51 in sequence. At the same time, the external loading equipment intermittently transports multiple blades into the rectangular feed port 51 and continues to push them inward to make them enter the corresponding storage troughs 531 until blades are transported into multiple storage troughs 531. At this time, multiple blades are respectively located on the corresponding top plate 549. Then, the external loading equipment pushes the front wheel disc from left to right to the upper side of the circular column 52, and the front and rear two screws 2 432 are controlled to rotate forward by the dual-axis motor 431. The front and rear two screws 2 432 respectively drive the corresponding clamping plates 43 4 approach each other until the front and rear clamping plates 434 approach each other to jointly clamp the front wheel disc. At this time, the front wheel disc is located directly above the circular column 52. Then, the front and rear lead screws 432 are controlled to reverse by the dual-axis motor 431. The front and rear lead screws 432 respectively drive the corresponding clamping plates 434 to move away from each other and return to their original positions. The feeding auxiliary mechanism 5 and the peripheral feeding equipment can sequentially convey multiple blades to the corresponding storage troughs 531, thereby completing the uniform feeding of the blades. The wheel disc clamping mechanism 4 can align and clamp the front wheel disc so that it is located directly above the circular column 52, which is convenient for the subsequent multiple blades to drive the front wheel disc to rise synchronously for feeding, thereby avoiding the time-consuming and labor-intensive problem of manually placing the blades in sequence during manual welding.

The upper ends of the two auxiliary sliding rods 322 slide through the rectangular plate 2 31 and are installed with a limiting circular plate.

[0049] After the current wheel is located directly above the circular column 52, the forward and reverse motor 3 543 is first used to control the screw 1 544 to rotate forward, and the screw 1 544 drives the annular mounting plate 547 to move upward through the mounting plate 545. The annular mounting plate 547 will drive multiple supporting slides 548 and multiple ejector rods 550 to move upward synchronously, and the multiple supporting slides 548 respectively drive the blades to move upward through the corresponding ejector plates 549 until the multiple blades all move upward to exit the storage trough 531. During this period, the multiple ejector rods 550 will drive the corresponding two supporting uprights 534 and two limit baffles 535 to move upward synchronously through the fan-shaped base 533. At this time, the multiple limit baffles 535 will exit the corresponding fan-shaped mounting grooves 532, and the multiple blades are respectively located at two adjacent The two hydraulic push rods 321 are then controlled to jointly drive the rectangular plate 2 31 to move downward. At this time, the circular plate 1 33, the blade clamping part 35 and the wheel disc clamping part 1 37 will all follow the rectangular plate 2 31 to move downward until the circular plate 2 355 moves downward to a position in contact with the upper end of the front wheel disc. The lifting clamping mechanism 3 and the feeding auxiliary mechanism 5 cooperate to drive multiple blades to move upward while driving multiple limit baffles 535 to move upward synchronously, thereby avoiding the problem of multiple blades tilting and collapsing. Multiple blades will drive the front wheel disc to move upward synchronously, and the circular plate 2 355 can be controlled to move downward to make it fit with the upper end of the front wheel disc, which is convenient for subsequent clamping of the blades and the front wheel disc.

A connecting slide rod 362 with a limiting circular plate on the upper end is installed on the upper end of the arc-shaped connecting plate 361. The connecting slide rod 362 is slidably connected to the corresponding arc-shaped waist hole 2 359 and the guide slide hole 1 358.

[0051] See Figure 1 、 Figure 8 、 Figure 9 and Figure 11 The blade clamping portion 35 also includes a second forward and reverse motor 363 installed on the second rectangular plate 31, and the output shaft of the second forward and reverse motor 363 is fixedly connected to the gear column 364. The cross-sections of the multiple arc-shaped support plates 34 are all L-shaped, and the multiple arc-shaped support plates 34 are commonly installed with an annular plate 365 at one end away from the second rectangular plate 31. The upper end of the annular plate 365 is rotatably installed with a transmission gear ring 366, which is engaged with the gear column 364. The annular plate 365 and the transmission gear ring 366 are also commonly provided with a blade clamping group. The difference is that the arc-shaped clamping plates 360 on the upper and lower sides are in opposite directions, and the upper arc-shaped clamping plate 360 is located at the lower side of the circular plate 355, and the lower arc-shaped clamping plate 360 is located at the upper side of the transmission gear ring 366.

[0052] See Figure 12-14The wheel clamping portion 1 37 includes a circular plate 371 fixedly mounted on the outer wall of the transmission shaft 354 at the upper side of the circular plate 1 33. The upper end of the circular plate 371 is provided with a plurality of arc-shaped waist holes 372 evenly distributed around the circumference. The upper end of the passive gear ring 352 is provided with a plurality of guide sliding holes 2 373 evenly distributed around the circumference. The upper end of the circular plate 371 is provided with a plurality of waist-shaped connecting rods 374 evenly distributed around the circumference. One end of the waist-shaped connecting rod 374 located on the circular plate 371 passes through A connecting slide rod 2 375 is installed, and the connecting slide rod 2 375 is slidably connected to the corresponding arc-shaped waist hole 372 and the guide slide hole 2 373. The lower end of the other end of the waist-shaped connecting rod 374 is installed with a support rod 2 376, and the lower end of the support rod 2 376 is installed with an arc-shaped splint 1 377. The upper end of the circular plate 371 is also symmetrically provided with an arc-shaped waist hole 1 356, and the front and rear support rods 1 357 are also slidably connected to the two arc-shaped waist holes 1 356 on the circular plate 371.

[0053] See Figure 1 、 Figure 3 and Figure 8 The lifting and clamping mechanism 3 also includes a forward and reverse motor 4 38 installed on the rectangular plate 2 31 , and the output shaft of the forward and reverse motor 4 38 is fixedly connected to an incomplete gear 2 39 , which is engaged with the passive gear ring 352 .

[0054] When the two hydraulic push rods 321 jointly drive the rectangular plate 2 31 to move downward, the circular plate 2 355, the annular plate 365 and the transmission gear ring 366 will all move downward with the rectangular plate 2 31. It should be noted that the multiple arc splints 1 360 are initially in a retracted state. First, the forward and reverse motor 1 353 is used to control the forward rotation of the transmission shaft 354, and the transmission shaft 354 drives the circular plate 1 33 to rotate. Under the cooperation of the arc waist hole 2 359 and the guide slide hole 1 358, the multiple connecting slide rods 1 362 will respectively drive the corresponding arc splints 1 360 to slide along the arc waist hole 2 359 until the multiple arc splints 1 360 corresponding to the connecting slide rods 1 362 all move to the end of the corresponding arc waist hole 2 359 away from the transmission shaft 354. At this time, the multiple arc splints corresponding to the connecting slide rods 1 362 One 360 becomes an extended state, and multiple blades are located between two adjacent arc-shaped clamping plates 1 360. During this period, the transmission shaft 354 will drive the circular plate three 371 to rotate. Under the cooperation of the arc-shaped waist hole three 372 and the guide slide hole two 373, multiple connecting slide rods 2 375 will drive the corresponding support rods 2 376 to slide along the corresponding guide slide hole 2 373 through the corresponding waist-shaped connecting rod 374 until the multiple connecting slide rods 2 375 all move to the end of the corresponding guide slide hole 2 373 close to the transmission shaft 354. At this time, the multiple support rods 2 376 respectively drive the corresponding arc-shaped clamping plates 2 377 to follow and move toward the transmission shaft 354, and jointly clamp the front wheel disc. It should be noted that during this period, the two support rods 1 357 will respectively perform adaptive sliding compensation along the corresponding arc-shaped waist hole 1 356.

[0055] Then, the incomplete gear 2 39 and the passive gear ring 352 are controlled by the forward and reverse motor 4 38 to drive the passive gear ring 352 to rotate at a suitable angle. The passive gear ring 352 drives the transmission shaft 354 to rotate synchronously through the barrel-shaped mounting seat 351. The transmission shaft 354 drives the corresponding multiple arc splints 1 360 to rotate synchronously through the circular plate 2 355. At this time, the corresponding multiple arc splints 1 360 will jointly push the multiple blades to make the multiple blades follow the swing. During this period, the multiple blades will push the adjacent limit baffles 535 to make them also follow the swing. At the same time, through the forward and reverse motor 4 The reversing motor 2 363 controls the gear column 364 to rotate forward, and the gear column 364 transmits the transmission gear ring 366, driving the transmission gear ring 366 to rotate. Under the cooperation of the arc-shaped waist hole 2 359 and the guide slide hole 1 358, the multiple connecting slide rods 1 362 will respectively drive the corresponding arc-shaped splint 1 360 to slide along the arc-shaped waist hole 2 359 until the arc-shaped splint 1 360 corresponding to the connecting slide rods 1 362 are all moved to the end of the corresponding arc-shaped waist hole 2 359 close to the axis of the transmission gear ring 366. At this time, the arc-shaped splint 1 corresponding to the connecting slide rods 1 362 360 becomes extended state, and the multiple arc-shaped clamping plates 360 corresponding to the circular plate 1 33 and the multiple arc-shaped clamping plates 360 corresponding to the transmission gear ring 366 will clamp the multiple blades together and further adjust the swing angle of the blades. When the multiple blades and the front wheel disc are clamped, the two hydraulic push rods 321 are controlled to jointly drive the rectangular plate 2 31 to move upward and return to the original position. At this time, the multiple blades and the front wheel disc will move upward accordingly. At this time, the upper end surfaces of the multiple limit baffles 535 will be lower than the height of the lower end surfaces of the multiple blades. Under the action of the torsion spring, the multiple limit baffles 535 will return to its original position, and then the forward and reverse motor three 543 will control the screw one 544 to reverse, and the screw one 544 will drive the annular mounting plate 547 to move downward through the mounting plate 545. The annular mounting plate 547 will drive multiple supporting slides 548 and multiple push rods 550 to move downward synchronously until they return to the corresponding fan-shaped mounting grooves 532 and storage troughs 531 and return to their original positions. During this period, under the action of the tension spring, the fan-shaped base 533 will drive the corresponding two supporting vertical rods 534 and two limit baffles 535 to move downward synchronously and return to their original positions.

[0056] The rear wheel disc is then pushed from left to right by the external loading equipment to the upper position of the circular column 52, and the front and rear two lead screws 2 432 are controlled to rotate forward by the dual-axis motor 431, and the front and rear two lead screws 2 432 respectively drive the corresponding clamping plates 434 to approach each other until the front and rear clamping plates 434 approach each other and clamp the rear wheel disc together. At this time, the front wheel disc is located at the position just above the circular column 52, and then the two hydraulic push rods 321 are controlled to jointly drive the rectangular plate 2 31 to move downward until the lower end faces of the multiple blades are tightly fitted with the upper end faces of the rear wheel disc, and the two external automatic welding robots can simultaneously weld the blades and the connection positions of the front and rear wheel discs. After welding is completed, the transmission shaft 354 is controlled to reverse by the forward and reverse motor 1 353. At this time, the multiple arc splints 1 360 corresponding to the disc 1 will become retracted and return to their original positions, and the multiple arc splints 1 360 will also release the front wheel disc and return to their original positions, and then the forward and reverse motor 2 363 controls the gear column 364 to reverse, at this time the multiple arc-shaped clamping plates 360 corresponding to the transmission gear ring 366 will become retracted and return to their original positions, and continue to control the front and rear two lead screws 2 432 to reverse through the dual-axis motor 431, and the front and rear two lead screws 2 432 respectively drive the corresponding clamping plates 434 to move away from each other and return to their original positions, and the welded fan impeller can be taken out by the external material-taking equipment, and the lifting clamping mechanism 3, the wheel clamping mechanism 4 and the feeding auxiliary mechanism 5 can cooperate to first drive the multiple blades to swing to a suitable angle, and then use the multiple arc-shaped clamping plates 360 on the upper and lower sides to clamp the multiple blades together, avoiding the problem of inconsistent inclination angles of the blades manually placed in sequence during manual welding, and can clamp the front and rear two wheel discs at the same time, and weld multiple blades and multiple welding positions of the front and rear two wheel discs at the same time, without the need for manual welding in sequence, effectively improving the welding efficiency and welding quality of multiple blades and the front and rear two wheel discs.
