DETAILED DESCRIPTION

[0022] Embodiment 1

[0023] like Figure 1-Figure 7 As shown, a steel ring laser welding device proposed in this embodiment includes a belt drawing and ring forming device and a laser welding device.

[0024] The belt looping device includes two sets of clamping and flipping mechanisms distributed side by side and a driving mechanism for driving the two sets of clamping and flipping mechanisms to move horizontally. The two sets of clamping and flipping mechanisms are respectively clamped at the inner side of the two ends of the steel belt, and the two ends of the steel belt are butted together after flipping to obtain a steel ring. A welding channel is left between the two sets of clamping and flipping mechanisms. When it is desired to weld steel rings of different sizes, steel belts of different lengths are prepared in advance, and the two ends of the steel belt are exposed. The two ends are clamped by two sets of clamping and flipping mechanisms at the inner side. When the clamping and flipping mechanisms drive the clamped steel belt to flip, the strip-shaped steel belt can be bent. After the two ends of the steel belt are butted together, they can be welded by a laser welding device in the subsequent process. It can be suitable for welding steel rings of different specifications. The steel belt is thin, with a thickness of only a few tenths of a millimeter. When the two ends of the steel belt are butted together, most of the lower part of the steel belt is naturally bent.

[0025] The laser welding device includes a second support frame 27, a translation plate 281, a second telescopic device 28 disposed on the second support frame 27 and driving the translation plate 281 to move horizontally, a moving plate 33 distributed in parallel with the translation plate 281, a third telescopic device 32 disposed on the translation plate 281 and driving the moving plate 33 to move horizontally, a first connecting frame 34 and a second connecting frame 36 disposed relatively on the moving plate 33, a laser welding head 35 disposed at the outer end of the first connecting frame 34, a set of flattening components disposed on each of the first connecting frame 34 and the second connecting frame 36, and a guide component for guiding the flattening components to move vertically. The second telescopic device 28 and the third telescopic device 32 both use a cylinder, an oil cylinder, an electric push rod or other structures that can achieve linear drive.

[0026] After the two ends of the steel strip are butted, the second telescopic device 28 drives the translation plate 281 to move horizontally, and the translation plate 281 drives the third telescopic device 32 to move horizontally, and the laser welding head 35 is moved to the welding channel. At this time, the laser welding head 35 is located above one end of the butt joint at the two ends of the steel ring. The third telescopic device 32 drives the moving plate 33 to move horizontally, so that the laser welding head 35 moves horizontally from above the butt joint at the two ends of the steel strip to perform laser welding at the butt joint. After welding, the thickness of the molten joint at the two ends of the steel ring may be different. At this time, the two sets of flattening components move toward each other and flatten the welding part, thereby improving the regularity of the steel ring structure. After the steel ring is welded and flattened, the steel ring is put down, and other subsequent treatments are performed by other equipment, such as curling, stretching, and chamfering the steel ring, so as to obtain a regular circular steel ring.

[0027] like Figure 7As shown, the flattening assembly includes a second spring 40, a vertically distributed sliding column 37 and a guide column 41, a roller 39 arranged at an outer end of the sliding column 37, and a pressure plate 38 arranged at an inner end of the sliding column 37 and the guide column 41. The outer end of the second spring 40 abuts against the wheel frame of the roller 39. In the two sets of flattening assemblies, the inner ends of the two second springs 40 abut against the first connecting frame 34 and the second connecting frame 36 respectively, the two sliding columns 37 are slidably arranged on the first connecting frame 34 and the second connecting frame 36 respectively, and the two guide columns 41 are slidably arranged on the first connecting frame 34 and the second connecting frame 36 respectively. When the moving plate 33 moves horizontally and the laser welding head 35 has not completed welding, the pressure plate 38 does not contact the steel belt. After the laser welding head 35 completes welding, the third telescopic device 32 drives the moving plate 33 to continue to move, the roller 39 rolls on the guide assembly, the second spring 40 is gradually compressed, the slide column 37 drives the pressure plate 38 to move, and the two pressure plates 38 move toward each other along the inclined direction until they are clamped on both sides of the welding part respectively to flatten the welding part. After the flattening process is completed, the second telescopic device 28 and the third telescopic device 32 retract, and the laser welding head 35 and the pressure plate 38 are removed from the steel ring to facilitate the subsequent removal of the steel ring.

[0028] like Figure 7 As shown, the guide assembly includes two vibration-inducing plates 30 symmetrically arranged on the translation plate 281, a first guide plate 29 arranged on the upper vibration-inducing plate 30, and a second guide plate 31 arranged on the lower vibration-inducing plate 30. The first guide plate 29 has a first guide slope 291 inclined downward, and the second guide plate 31 has a second guide slope inclined upward. The first guide slope 291 and the second guide slope respectively guide the rolling direction of the two rollers 39 in the two groups of flattening assemblies. When the laser welding head 35 completes welding and continues to move, the two rollers 39 roll on the first guide slope 291 and the second guide slope respectively, the second spring 40 is compressed, and the two pressure plates 38 move toward each other and are respectively pressed on both sides of the welding position for flattening.

[0029] The surface of the vibration-inducing plate 30 facing the flattening assembly has a plurality of bosses 301 distributed at equal distances. When the pressing plate 38 moves away from the welding part, welding slag may be attached. When the roller 39 rolls to the boss 301 on the vibration-inducing plate 30, it will vibrate up and down, thereby driving the pressing plate 38 to vibrate and shake off the welding slag. A support box 42 is provided at the bottom of the translation plate 281. The length and width of the support box 42 are larger than the corresponding dimensions of the pressing plate 38, the second connecting frame 36 and the vibration-inducing plate 30. The shaken welding slag will fall into the support box 42 for collection. In order to limit the range of welding slag falling, protruding side plates 381 are provided at both ends of the length direction of the pressing plate 38. The side plates 381 on the two pressing plates 38 are staggered, and the distance between the two side plates 381 on the lower pressing plate 38 is larger, so that the welding slag is easier to accurately fall into the support box 42. In addition, the two ends of the pressing plate 38 in the width direction can also be chamfered to facilitate the falling of welding slag.

[0030] This embodiment can connect steel strips of different lengths into steel rings of different sizes for welding, has a wide range of applications, and can ensure welding quality and efficiency. According to the size of the steel ring to be welded, a steel strip of corresponding length is prepared in advance, and two sets of clamping and flipping mechanisms are used to clamp the two parts of the steel strip near the two ends respectively, and then move towards each other and flip, and finally connect the two ends of the steel strip to obtain a ring-shaped steel ring. The laser welding head 35 performs laser welding on the joint of the steel strip during the movement, and after the welding is completed, the welding part is flattened by the pressing plate 38 to improve the regularity of the steel ring structure.

[0031] Embodiment 2

[0032] like Figure 1-Figure 7 As shown, a steel ring laser welding device proposed in this embodiment, compared with the first embodiment, in this embodiment, the clamping and flipping mechanism includes a third motor 11, a turntable 12 connected to the output end of the third motor 11, a fourth motor 14 arranged on the turntable 12, a gear 15 connected to the output end of the fourth motor 14, two groups of linkage components distributed on both sides of the gear 15, a first crossbar 20 and a second crossbar 22 respectively connected to the two groups of linkage components, a clamping platform 21 arranged on the first crossbar 20, and a crimping component arranged on the second crossbar 22. The fourth motor 14 can drive the gear 15 to rotate, and the gear 15 drives the two groups of linkage components to move in opposite directions, so as to achieve the purpose of the first crossbar 20 and the second crossbar 22 moving in opposite directions, and then the clamping platform 21 and the crimping component are moved toward or away from each other, and the steel strip can be clamped when moving toward each other. The output end of the third motor 11 can rotate forward and reverse, and can drive the turntable 12 to rotate, and the turntable 12 drives the fourth motor 14 to rotate, so as to flip the end of the steel strip, bend the steel strip into a steel ring and dock the two ends.

[0033] like Figure 3As shown, the linkage assembly includes a connecting column 17 disposed on the rotating disk 12, a sliding rod 18 slidably disposed on the connecting column 17, an end plate 19 connected to the end of the sliding rod 18, and a rack 16 disposed on the end plate 19 and meshingly connected with the gear 15. In the two sets of linkage assemblies, the two racks 16 are respectively connected to the first crossbar 20 and the second crossbar 22, and the other ends of the two sliding rods 18 are respectively connected to the first crossbar 20 and the second crossbar 22. The gear 15 drives the two racks 16 to move simultaneously, and the two racks 16 are parallel but move in opposite directions. The sliding rod 18 slides on the connecting column 17 to guide the rack 16 and enables the first crossbar 20 and the second crossbar 22 to move in opposite directions.

[0034] like Figure 3 As shown, the crimping assembly includes a connecting platform 23 arranged on the second crossbar 22, a clamping plate 24 arranged on the connecting platform 23 by rotating the shaft, a first spring 25 connected between the connecting platform 23 and the clamping plate 24, and a torsion spring 26 sleeved on the outer circumference of the shaft and with both ends respectively abutting against the connecting platform 23 and the clamping plate 24. In the initial state where the two sets of clamping and flipping mechanisms clamp the two ends of the steel strip respectively, the clamping platform 21 clamps the lower surface of the steel strip, and the clamping plate 24 clamps the upper surface of the steel strip. When the two sets of clamping and flipping mechanisms flip the two ends of the steel strip and connect them into a steel ring, as shown in FIG. Figure 6 As shown, the clamping platform 21 is located outside the steel ring, and the clamping plate 24 is located inside the steel ring. When the steel strip is clamped by the clamping and flipping mechanism, the clamping plate 24 compresses the first spring 25 and twists the torsion spring 26. Further, an arc guide cylinder can be provided on the connecting platform 23, and an arc rod slidably connected to the arc guide cylinder can be provided on the clamping plate 24. The arc guide cylinder and the arc rod are both centered on the central axis of the rotation connection between the connecting platform 23 and the clamping plate 24. The first spring 25 is sleeved on the outer peripheral side of the arc guide cylinder and the arc rod, and can be stably extended and retracted without falling off.

[0035] After the laser welding head 35 has finished welding the steel ring and removed, the clamping plate 24 and the clamping platform 21 in the clamping flipping mechanism release the clamping of the steel ring, the first spring 25 pushes the clamping plate 24 to rotate upward, and the torsion spring 26 drives the clamping plate 24 to rotate upward. The clamping plate 24 rotates to an inclined state, and the steel ring will slide from the upper surface of the inclined clamping plate 24 under the action of its own gravity, realizing automatic unloading. A horizontally distributed receiving platform 43 is set at the bottom of the first support frame 1 and the second support frame 27 to receive the automatically unloaded steel ring.

[0036] The driving mechanism includes a first support frame 1, a first screw rod 911 and a second screw rod 921 which are parallelly distributed and both rotatably arranged on the first support frame 1, a first motor 91 and a second motor 92 which are arranged on the first support frame 1 and are used to drive the first screw rod 911 and the second screw rod 921 respectively, a first moving platform 81 and a second moving platform 82 which are respectively threadedly connected to the first screw rod 911 and the second screw rod 921, a first moving platform 71 and a second moving platform 72 which are respectively arranged on the first moving platform 81 and the second moving platform 82, and a guide rod 10 which is arranged on the first support frame 1. The first moving platform 81 and the second moving platform 82 are both slidably arranged on the guide rod 10, and the two third motors 11 in the two groups of clamping and flipping mechanisms are respectively arranged on the first moving platform 71 and the second moving platform 72. The first motor 91 can drive the first screw rod 911 to rotate forward and reversely, the first screw rod 911 drives the first moving platform 81 to move, the guide rod 10 guides the moving process, the first moving platform 81 drives the first moving platform 71 to move, and the first moving platform 71 drives the third motor 11 to move, thereby adjusting the position of a group of clamping and flipping mechanisms. Similarly, the position of another set of clamping and flipping mechanisms can be adjusted by driving the second motor 92. The first moving frame 71 and the second moving frame 72 are both provided with a fixing ring 13 rotatably connected to the rotating disk 12, thereby improving the stability of the rotating disk 12 during rotation.

[0037] like Figure 1 and Figure 2 As shown, the laser welding equipment also includes two steel strip rollers 4 rotatably arranged on the first support frame 1 and used for rolling and clamping the steel strip, a support table 2 having a plurality of through-channels 201 penetrating from top to bottom and a cutting groove 202 located on the top surface, a cutter 5 facing the cutting groove 202, and a first telescopic device 6 for driving the cutter 5 to rise and fall. The first telescopic device 6 can be an air cylinder or an oil cylinder, which can drive the cutter 5 to rise and fall vertically. When the cutter 5 is lowered, the bottom end of the cutter 5 can extend into the cutting groove 202 to cut the steel strip on the support table 2. The support table 2 and the first telescopic device 6 are both arranged on the first support frame 1. The clamping table 21 has a plurality of bosses that can pass through the through-channels 201, so that the clamping table 21 in the clamping and flipping mechanism can pass through the through-channels 201 through the bosses, and use the top of the bosses to clamp the steel strip.

[0038] If you want to make a steel ring of the required size, you need to make a steel strip of the corresponding length first. The steel strip is unwound from the steel coil raw material, passes between the two steel strip rollers 4, and is placed on the top surface of the support 2. The outer end of the steel strip is clamped by the clamping and flipping mechanism on the second mobile frame 72, and the steel strip is pulled to the desired position at a distance. Before cutting the steel strip, the clamping and flipping mechanism on the first mobile frame 71 is adjusted to the support 2 in advance, and the steel strip is clamped by the clamping and flipping mechanism. The cutting position of the steel strip by the cutter 5 is located between the steel strip roller 4 and the clamping and flipping mechanism. There is rotational damping between the steel strip roller 4 and the first support frame 1, and the cutter 5 can cut the steel strip regularly. The cutting groove 202 is located in the upper area of ​​the through channel 201. After the steel strip is cut, the two sets of clamping and flipping mechanisms move to a distance at the same time, and then move toward each other. During the movement toward each other, the ends of the steel strip are flipped, and finally the two ends of the steel strip are butt-jointed.

[0039] When the clamping and flipping mechanism is used to clamp the steel strip at the support platform 2, the clamping platform 21 moves up, the connecting platform 23 moves down, and the boss portion of the clamping platform 21 moves up through the through channel 201. The clamping plate 24, which is tensioned by the first spring 25 and the torsion spring 26, is in an inclined state. As the connecting platform 23 continues to move down, the clamping plate 24 slides on the edge of the support platform 2, and the clamping plate 24 gradually rotates to a horizontal state. The first spring 25 is gradually compressed, and the torsion spring 26 is gradually twisted. The boss portion of the clamping platform 21 and the clamping plate 24 are clamped on the lower surface and the upper surface of the steel strip respectively to achieve a stable clamping. In addition, a raised side strip 3 can be set at the edge of the top surface of the support platform 2, and the clamping plate 24 slides on the side strip 3 instead of sliding on the support platform 2. The thickness of the side strip 3 is slightly smaller than the thickness of the steel strip, which prevents the clamping plate 24 from crimping and dragging the steel strip too far during the rotation of the clamping plate 24 to the horizontal state, and can also ensure that the clamping platform 21 and the clamping plate 24 can effectively pull the steel strip outward after clamping the steel strip.

[0040] After welding a steel ring, the steel ring is removed. The inner-distributed clamping and flipping mechanism moves toward the pallet 2. The clamping and flipping mechanism first clamps the outer end of the steel coil material, then drags it toward the end of the pallet 2, then releases the steel strip and moves in the opposite direction. Another set of clamping and flipping mechanisms is moved to the pallet 2 to clamp the steel strip on the pallet 2. The clamping position is located in the area slightly inward of the end of the steel strip. Then, the outer clamping and flipping mechanism pulls the steel strip outward to the desired position, clamps the steel strip through the inner clamping and flipping mechanism, and cuts the steel strip through the cutter 5.

[0041] This embodiment can clamp the steel strip, and after clamping the two ends of the steel strip, the steel strip can be flipped into a steel ring for docking, so that laser welding can be performed at the docking point using the laser welding head 35. After welding, the clamping and flipping mechanism releases the clamping of the steel ring, and the steel ring automatically slides down along the inclined clamping plate 24, realizing automatic unloading.

[0042] The embodiments of the present invention are described in detail above with reference to the accompanying drawings, but the present invention is not limited thereto, and various changes can be made within the knowledge scope of technicians in the relevant technical field without departing from the purpose of the present invention.
