Description

Technical Field

[0001] The invention belongs to the technical field of mechanical manufacturing, and more specifically, particularly relates to a laser multi-head automatic switching composite multi-axis processing equipment. Background Art

[0002] Laser welding is an advanced welding technology that uses a high-energy-density laser beam as a heat source to achieve material connection. Laser welding has many advantages. First, it has a fast welding speed and can significantly improve production efficiency. Secondly, due to the small spot size and concentrated energy of the laser beam, the welding heat-affected zone is small, which can reduce thermal damage to surrounding materials and maintain the good performance of the welded joint. Furthermore, it can achieve high-precision welding and is suitable for occasions with high requirements for welding accuracy.

[0003] However, the existing laser multi-head automatic switching composite multi-axis processing equipment still has the following shortcomings when used:

[0004] 1. Most existing welding equipment is fixed by external clamping. The fixing method is relatively simple and cannot be changed according to needs. For example, when fixing and welding aluminum alloy or copper round tubes, it is difficult to ensure the size and uniform distribution of the clamping force by applying pressure externally, which may cause large indentations or deformation of the round tube, thus causing damage;

[0005] 2. Most traditional welding equipment is not equipped with the function of automatically cleaning welding slag, which requires manual labor to spend a lot of time and energy to clean. Manual cleaning is not only inefficient and increases labor costs, but also if it is not cleaned in time, the accumulated welding slag may interfere with the normal operation of the equipment, have an adverse effect on the welding quality, and even shorten the service life of the equipment.

[0019] Compared with the prior art, the present invention has the following beneficial effects:

[0020] In the present invention, when laser beam welding is performed on two solid circular tubes, the two sections of solid circular tubes can be placed in two groups of clamping strips respectively, and then the third internal threaded ring is rotated on the driven rod. Since the two are threadedly connected, the two third internal threaded rings will move relatively when rotating, and the two groups of clamping strips will be squeezed by the movement of the two third internal threaded rings. At this time, the two groups of clamping strips will be forced to move toward the middle in the two groups of L-shaped grooves. The solid circular tube will be fixed under the movement of the two groups of clamping strips, and the two groups of second springs will be compressed accordingly. At this time, the two second driving motors can be started through the control panel, and the two second driving motors drive the two third screws to rotate at the same frequency, one clockwise and the other counterclockwise, so that the two solid circular tubes rotate synchronously and remain relatively still. At this time, the composite laser welding head can be controlled to switch through the control panel to weld the two solid circular tubes. When laser beam welding is required for hollow circular tubes, the two cylinders can be rotated left and right on the two cylinders. The two rotating rods are rotated in the right and left directions, and the two rotating rods and the two third screws are rotated from the horizontal state to the vertical state, and then the two rotating rods are fixed by the first internal threaded ring. At this time, the two hollow circular tubes are put on the two fixed cylinders, and then the two fourth screws can be rotated inside the two fixed cylinders. Since the two are threadedly connected, the three wedge blocks will be squeezed under the rotation of the fourth screw. At this time, the three wedge blocks will slide out of the three inner grooves to resist and fix the inner walls of the two solid circular tubes. Then the three groups of first springs will be stretched accordingly. At this time, the equipment can be controlled by the control panel to weld the two solid circular tubes. The equipment realizes efficient, accurate, convenient and stable fixing and welding operations of solid circular tubes and hollow circular tubes through ingenious mechanical structure design, reduces the difficulty and error of manual operation, and greatly improves welding efficiency and quality. At the same time, it has strong versatility, can meet the welding needs of different types of circular tubes, and adapt to diversified production scenarios.

[0021] In the present invention, the slag receiving plate can be placed on the second adjustment platform when in use. When one rotating rod is flipped to the left side of the equipment and is perpendicular to the third screw, the two second internal threaded rings can be rotated on the driven rod. The gear will move horizontally under the rotation of the two second internal threaded rings. At this time, the gear will slide to a state of meshing with the rack. At this time, when the second driving motor drives the third screw to rotate, the driven plate will shake with the third screw as the central axis. Under the influence of the driven plate, the driven rod and the connecting part thereof will swing, and the part away from it will swing like a clock inside the vertical rod. At this time, the gear will swing accordingly. Since the gear is meshing with the rack, Therefore, the rack will drive the limit block and the cleaning scraper to slide inside the limit groove and the guide groove respectively. The sliding of the cleaning scraper will scrape and clean the accumulated welding slag on the guide groove. The scraped welding slag will fall from the discharge chute to the slag receiving plate to complete the collection. The equipment realizes the automatic scraping, cleaning and collection of the accumulated welding slag on the equipment. This design not only greatly reduces the tedious work of manual cleaning of welding slag and improves the cleaning efficiency, but also avoids the adverse effects of welding slag accumulation on the normal operation of the equipment and the welding quality, ensuring the continuous and stable operation of the equipment, reducing maintenance costs, and improving the overall production efficiency and the continuity of welding work.

[0022] In the present invention, by designing the gears into two groups, only one gear can be used to drive the rack to slide, and the other gear can be in an idle state for standby. When the working gear fails or is damaged, the idle gear can be quickly activated to ensure that the welding slag scraping work can be carried out uninterruptedly, reduce production stagnation caused by equipment failure, and improve the reliability of the entire system. The idle gear is used as a spare part and can replace the working gear during regular maintenance for maintenance and repair, which helps to extend the overall service life of the gear.

[0023] In the present invention, when in use, the second hydraulic oil cylinder can be controlled to start through the control panel, and the second hydraulic oil cylinder will drive the second electric telescopic rod to extend and retract, thereby driving the first adjusting platform to slide on the adjusting frame to adjust the front and rear positions of processing. The first driving motor can also be controlled to start through the control panel, and the first screw rod will be driven to rotate under the action of the first driving motor, and the U-shaped connecting frame threadedly connected thereto will be driven to slide inside the first slide groove under the action of the first screw, thereby adjusting the left and right positions of processing. The first hydraulic oil cylinder can also be controlled to start through the control panel, and the first electric telescopic rod will be driven to extend and retract under the action of the first hydraulic oil cylinder. At this time, the first electric telescopic rod will push the third adjusting platform to move upward, and the movement of the third adjusting platform will drive the inner sliding column to slide inside the outer sliding cylinder, thereby adjusting the processing height. Through composite multi-axis adjustment, the equipment can accurately adjust the position of the processing parts in the front and rear, left and right and height directions. This multi-dimensional flexible adjustment function greatly improves the processing precision and accuracy.

[0024] In the present invention, when the round tube needs to be disassembled, the fourth screw rod or the third internal threaded ring can be rotated on the equipment to loosen the two ends of the round tube, and then the two second screw rods can be rotated on the third adjusting platform. Since the two second screw rods are rotatably connected to the two sliders respectively, the rotation of the two second screw rods will drive the two sliders to slide to the two ends, and the two sliders will drive the two discs to slide to the two ends, thereby completing the disassembly of the round tube, making it more convenient to disassemble and take out the round tube after welding is completed.

By designing the gears 58 into two groups, only one gear 58 can drive the rack 37 to slide, and the other can be in an idle state for standby. When the working gear 58 fails or is damaged, the idle gear 58 can be quickly activated to ensure that the welding slag scraping work can be carried out uninterruptedly, reduce production stagnation caused by equipment failure, and improve the reliability of the entire system.

[0041] Working principle:

[0042] In the first step, when laser beam welding is performed on two solid round tubes, the two sections of solid round tubes can be placed in two groups of clamping strips 64 respectively, and then the third internal thread ring 61 is rotated on the driven rod 56. Since the two are threadedly connected, the two third internal thread rings 61 will move relative to each other during rotation. Under the movement of the two third internal thread rings 61, the two groups of clamping strips 64 will be squeezed. At this time, the two groups of clamping strips 64 will be forced to move toward the middle in the two groups of L-shaped grooves 63. Under the movement of the two groups of clamping strips 64, the solid round tube will be welded. The two sets of second springs 65 are fixed and compressed at the same time. At this time, the two second drive motors 45 can be started through the control panel 13. The two second drive motors 45 drive the two third screws 46 to rotate clockwise and counterclockwise at the same frequency, so that the two solid circular tubes rotate synchronously and remain relatively still. At this time, the composite laser welding head 14 can be switched through the control panel 13 to weld the two solid circular tubes. When the hollow circular tube needs to be laser beam welded, the composite laser welding head 14 can be switched on the two cylinders 42. The two rotating rods 54 are rotated in the left and right directions, and the two rotating rods 54 and the two third screw rods 46 are rotated from the horizontal state to the vertical state, and then the two rotating rods 54 are fixed by the first internal threaded ring 43. At this time, the two hollow circular tubes are sleeved on the two fixed cylinders 48, and then the two fourth screw rods 51 can be rotated inside the two fixed cylinders 48. Since the two are threadedly connected, the three wedge blocks 52 will be squeezed under the rotation of the fourth screw rod 51. At this time, the three wedge blocks 52 will slide out inside the three inner grooves 49 to resist and fix the inner walls of the two solid circular tubes. Then the three groups of first springs 53 will be stretched accordingly. At this time, the control panel 13 can be used to control the equipment to weld the two solid circular tubes. The equipment realizes efficient, accurate, convenient and stable fixing and welding operations of solid circular tubes and hollow circular tubes through ingenious mechanical structure design, reduces the difficulty and error of manual operation, and greatly improves welding efficiency and quality. At the same time, it has strong versatility, can meet the welding needs of different types of circular tubes, and adapt to diversified production scenarios.

[0043] In the second step, the slag receiving plate can be placed on the second adjustment platform 22. When one rotating rod 54 is flipped to the left side of the equipment and is perpendicular to the third screw rod 46, the two second internal threaded rings 59 can be rotated on the driven rod 56. Under the rotation of the two second internal threaded rings 59, the gear 58 will move horizontally. At this time, the gear 58 will slide to a state of meshing with the rack 37. At this time, when the second driving motor 45 drives the third screw rod 46 to rotate, the driven plate 47 will shake with the third screw rod 46 as the central axis. Under the influence of the driven plate 47, the driven rod 56 and the connecting part thereof will swing, and the part away from it will swing like a clock inside the vertical rod 55. At this time, the gear 58 will swing accordingly. Since the gear 58 is meshed with the rack 37, the rack 37 will drive the limit block 3 6 and the cleaning scraper rod 35 slide in the limiting groove 34 and the guide groove 31 respectively. The sliding of the cleaning scraper rod 35 will scrape and clean the accumulated welding slag dropped on the guide groove 31. The scraped welding slag will fall from the discharge chute 29 to the slag receiving plate to complete the collection. When welding a solid circular tube, the welding slag can be automatically cleaned after welding, and when welding a hollow circular tube, the welding can be automatically cleaned while welding. The device can be selected arbitrarily. The device realizes the automatic scraping, cleaning and collection of the accumulated welding slag on the equipment. This design not only greatly reduces the tedious work of manually cleaning welding slag, improves the cleaning efficiency, but also avoids the adverse effects of welding slag accumulation on the normal operation of the equipment and the welding quality, ensures the continuous and stable operation of the equipment, reduces the maintenance cost, and improves the overall production efficiency and the continuity of the welding work.

[0044] The third step is to design the gear 58 into two groups, so that only one gear 58 can drive the rack 37 to slide, and the other gear can be in an idle state for standby. When the working gear 58 fails or is damaged, the idle gear 58 can be quickly activated to ensure that the welding slag scraping work can be carried out uninterruptedly, reduce production stagnation caused by equipment failure, and improve the reliability of the entire system. The idle gear 58, as a spare part, can replace the working gear 58 during regular maintenance for maintenance and repair, which helps to extend the overall service life of the gear 58;

[0045] The fourth step is to control the second hydraulic cylinder 71 to start through the control panel 13 during use. The second hydraulic cylinder 71 will drive the second electric telescopic rod 72 to extend and retract, thereby driving the first adjustment platform 16 to slide on the adjustment frame 15 to adjust the front and rear positions of the processing. The first driving motor 19 can also be controlled to start through the control panel 13. Under the action of the first driving motor 19, the first screw 21 will be driven to rotate. Under the action of the first screw 21, the U-shaped connecting frame 23 threadedly connected thereto will be driven to slide inside the first slide groove 17 to adjust the left and right positions of the processing. The first hydraulic cylinder 24 can also be controlled to start through the control panel 13. Under the action of the first hydraulic cylinder 24, the first electric telescopic rod 25 will be driven to extend and retract. At this time, the first electric telescopic rod 25 will push the third adjustment platform 27 to move upward. Under the movement of the third adjustment platform 27, the inner slide column 28 will be driven to slide inside the outer slide cylinder 26, thereby adjusting the processing height. Through composite multi-axis adjustment, the equipment can accurately adjust the position of the processing parts in the front and rear, left and right and height directions. This multi-dimensional flexible adjustment function greatly improves the processing precision and accuracy.

[0046] In the fifth step, when the round tube needs to be disassembled, the fourth screw rod 51 or the third internal threaded ring 61 can be rotated on the equipment to loosen the two ends of the round tube, and then the two second screw rods 32 can be rotated on the third adjusting platform 27. Since the two second screw rods 32 are rotatably connected to the two sliders 38 respectively, the rotation of the two second screw rods 32 will drive the two sliders 38 to slide to the two ends, and the two sliders 38 will drive the two discs 41 to slide to the two ends, thereby completing the disassembly of the round tube, making it more convenient to disassemble and take out the round tube after welding is completed.
