Description

Technical Field

[0001] The invention relates to the technical field of welding equipment, and in particular to a laser welding machine. Background Art

[0002] With the development of industrial technology, laser welding machines are widely used in various welding operations due to their high efficiency and precision, especially in high-altitude operations, such as high-rise buildings and bridge construction. Laser welding machines use high-energy-density laser beams to weld materials, with the advantages of fast speed, small heat-affected zone, and small welding deformation, which greatly improves welding quality and production efficiency. However, existing small laser welding machines have some significant safety hazards when working at high altitudes.

[0003] During aerial work, operators need to frequently move the welding gun to perform welding operations. Due to the quality and design of the welding machine itself, the welding machine is easily pulled by the welding gun, causing the equipment to move during the operation. This movement not only affects the welding quality and efficiency, but also may cause the risk of the equipment falling from a height. Especially in aerial working environments such as high-rise buildings and bridge construction, unexpected movement of equipment may cause serious safety accidents and endanger the lives of operators and other workers.

[0004] The purpose of the present invention is to solve the problem that the existing small laser welding machine is easily pulled by the welding gun during high-altitude operation and thus falls from the high altitude, causing potential safety hazards. Summary of the invention

[0005] In order to solve the problem that the existing small laser welding machine is easily pulled by the welding gun and falls from the high altitude during high-altitude operation, causing safety hazards, the present invention adopts the following technical solutions: A laser welding machine comprises a welding machine and a warning mechanism installed at the bottom of the welding machine, wherein a first disc is installed at the bottom of the welding machine, the warning mechanism comprises a second disc, a sliding mechanism is installed in the second disc, the sliding mechanism comprises an outer cylinder, a second copper ring is sleeved in the outer cylinder, the second copper ring is fixedly connected to the inner wall of the outer cylinder, an inner cylinder is sleeved in the outer cylinder, a first copper ring is sleeved outside the inner cylinder, the first copper ring is fixedly connected to the inner cylinder, an upper cover is provided on the top of the inner cylinder, a speaker and a battery are installed in the upper cover, a wire is installed at one end electrode of the battery, one end of the wire is electrically connected to the second copper ring, the other end electrode of the battery is electrically connected to one end electrode of the speaker, and the other end electrode of the speaker is electrically connected to the first copper ring; At least one support block is installed on the top of the upper cover, a connecting plate is fixedly connected to the top of the support block, a connecting column is installed on the top surface of the connecting plate, a top plate is installed on the top of the connecting column, and the top plate is fixedly connected to the bottom of the welding machine; A circular ring is arranged on the top of the outer cylinder, the inner hole diameter of the circular ring is smaller than the diameter of the connecting plate, the connecting plate is arranged below the circular ring, and the top plate is arranged above the circular ring.

[0006] Preferably, a plurality of second balls are installed on the top of the circular ring, the second balls are rotatably connected to the circular ring, and the second balls are used to support the top plate.

[0007] Preferably, a bottom plate is provided at the bottom of the inner cylinder, and a plurality of first balls are installed at the bottom of the bottom plate, wherein the first balls are rotatably connected to the bottom plate, and the first balls are used to support the inner cylinder.

[0008] Preferably, at least one magnetic attraction mechanism is installed on the second disc, and the magnetic attraction mechanism includes a cylinder, a side wall of the cylinder is provided with a slide groove, a partition is provided in the cylinder, a screw rod is sleeved in the partition, the screw rod is threadedly connected to the partition, a handle is installed on one side of the screw rod, the height of the slide groove is higher than the height of the handle, and a magnet block is installed at the bottom end of the screw rod.

[0009] Preferably, a slot is provided at the bottom end of the screw rod, a rotating block is fixedly connected to the top of the magnet block, the rotating block is arranged in the slot, and the slot is rotatably connected to the rotating block.

[0010] Preferably, a plurality of support columns are installed on the top of the second disc, a third ball is installed on the top of the support column, the third ball is rotatably connected to the support column, and the third ball is used to support the first disc.

[0011] Preferably, the conductive wire is in a spiral shape.

[0012] Preferably, one end of the handle is provided with a rubber pad.

[0013] Preferably, the welding machine comprises an interface for connecting a welding gun.

[0014] Preferably, at least one handle is installed on the top of the welding machine.

[0015] Compared with the prior art, the present invention has the following beneficial effects: 1. In the present invention, through the design of the warning mechanism, when the welding machine moves beyond the set safety distance, the speaker will sound an alarm to promptly remind the operator to stop moving, effectively preventing the welding machine from falling from a high altitude and avoiding the occurrence of safety accidents. Specifically, when the operator pulls the welding gun, the welding machine will drive the inner cylinder to slide. Since the warning mechanism has a large friction with the ground and remains relatively still, and does not move with the welding machine, the sliding of the inner cylinder causes the first copper ring and the second copper ring to gradually approach each other. When the inner cylinder slides to the set safety distance, the first copper ring and the second copper ring contact to form a closed circuit. After the circuit is closed, the battery supplies power to the speaker through the wire, and the speaker sounds an alarm to remind the operator that the welding machine has moved beyond the safety range. 2. In the present invention, the magnetic attraction mechanism is adsorbed on the metal surface by the magnet block, which increases the stability of the welding machine and prevents it from falling due to accidental movement, especially when working at heights, which significantly improves the safety of the operation. Specifically, the operator rotates the handle to move the screw rod downward along the thread of the partition. As the screw rod descends, the magnet block gradually extends out of the cylinder and eventually contacts the metal surface. When the magnet block contacts the metal surface, it immediately generates magnetic force, which firmly adsorbs the welding machine on the metal surface, increasing the stability of the welding machine. Especially when working at heights, this magnetic attraction design can effectively prevent the welding machine from falling from a height due to accidental movement, and avoid the risk of equipment damage and personal injury caused by the falling of the equipment; 3. In the present invention, the magnetic attraction can be activated or released by rotating the handle, which is simple and quick to operate without complicated tools or steps. The design of the rubber pad increases the friction during operation, making the operation more labor-saving and comfortable.

[0016] In summary, the present invention solves the problem that the existing small laser welding machine is easily pulled by the welding gun during high-altitude operation and thus falls from a high altitude, causing a safety hazard. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0019] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0020] Embodiment 1: This embodiment provides a laser welding machine, see Figure 1-10, comprising a welding machine 1, a warning mechanism 2 installed at the bottom of the welding machine 1, the welding machine 1 comprising an interface for connecting a welding gun, a first disc 11 being installed at the bottom of the welding machine 1, the warning mechanism 2 comprising a second disc 21, a sliding mechanism 22 being installed in the second disc 21, the sliding mechanism 22 comprising an outer cylinder 222, a second copper ring 2214 being sleeved in the outer cylinder 222, the second copper ring 2214 being fixedly connected to the inner wall of the outer cylinder 222, an inner cylinder 2211 being sleeved in the outer cylinder 222, the inner cylinder 22 The outer sleeve 11 is provided with a first copper ring 223, the first copper ring 223 is fixedly connected to the inner tube 2211, the top of the inner tube 2211 is provided with an upper cover 224, a speaker 225 and a battery 226 are installed in the upper cover 224, one end electrode of the battery 226 is installed with a wire 227, one end of the wire 227 is electrically connected to the second copper ring 2214, the other end electrode of the battery 226 is electrically connected to one end electrode of the speaker 225, and the other end electrode of the speaker 225 is electrically connected to the first copper ring 223; At least one support block 228 is installed on the top of the upper cover 224, and a connecting plate 2215 is fixedly connected to the top of the support block 228. A connecting column 2216 is installed on the top surface of the connecting plate 2215, and a top plate 221 is installed on the top of the connecting column 2216. The top plate 221 is fixedly connected to the bottom of the welding machine 1; A circular ring 2212 is disposed on the top of the outer cylinder 222 . The inner diameter of the circular ring 2212 is smaller than the diameter of the connecting plate 2215 . The connecting plate 2215 is disposed below the circular ring 2212 , and the top plate 221 is disposed above the circular ring 2212 .

[0021] In the specific implementation process, Figures 1 to 10 As shown, when in use, the welding gun is connected to the laser welding machine. When the operator pulls the welding gun, the welding gun will drive the laser welding machine to rotate or move. The warning mechanism 2 will not move due to the friction with the receiving platform. Once the welding machine 1 moves to the set distance, the speaker 225 will emit a warning sound, thereby reminding the operator not to continue moving the welding machine 1, and further avoiding the welding machine 1 from falling from a high height. Specifically, when the operator pulls the welding gun to cause the welding machine 1 to move, the warning mechanism 2 remains relatively still due to the large friction with the ground, and does not move with the welding machine 1. The welding machine 1 drives the inner cylinder 2211 to slide, and the movement of the inner cylinder 2211 causes the first copper ring 223 and the second copper ring 2214 to contact, thereby forming a closed circuit. After the circuit is closed, the battery 226 supplies power to the speaker 225, and the speaker 225 emits an alarm sound to remind the operator that the welding machine 1 has moved beyond a safe range.

[0022] like Figure 1-10As shown, a plurality of second rolling balls 2213 are installed on the top of the circular ring 2212 , and the second rolling balls 2213 are rotatably connected to the circular ring 2212 , and the second rolling balls 2213 are used to support the top plate 221 .

[0023] In the specific implementation process, the second ball 2213 can roll freely on the ring 2212, greatly reducing the friction between the top plate 221 and the ring 2212. This design makes the inner cylinder 2211 smoother when sliding, reducing the jamming or resistance caused by excessive friction. Due to the reduction of friction, the sliding of the inner cylinder 2211 is more sensitive, and it can respond to the movement of the welding machine 1 more quickly, thereby triggering the alarm more timely. The design of the ball reduces the direct contact between the components, thereby reducing wear. This not only extends the service life of the top plate 221 and the ring 2212, but also reduces the maintenance cost. Multiple balls are evenly distributed on the top of the ring 2212, which can better disperse the pressure of the top plate 221 and avoid deformation or damage caused by excessive local force.

[0024] like Figure 1-10 As shown, a bottom plate 229 is provided at the bottom of the inner cylinder 2211 , and a plurality of first balls 2210 are installed at the bottom of the bottom plate 229 , and the first balls 2210 are rotatably connected to the bottom plate 229 , and the first balls 2210 are used to support the inner cylinder 2211 .

[0025] In the specific implementation process, the first ball 2210 can roll freely at the bottom of the bottom plate 229, greatly reducing the friction between the inner cylinder 2211 and the ground or other supporting platforms. This design makes the inner cylinder 2211 smoother when sliding, reducing the jamming or resistance caused by excessive friction. Due to the reduction of friction, the sliding of the inner cylinder 2211 is more sensitive, and it can respond to the movement of the welding machine 1 more quickly, thereby triggering the alarm more timely. The rolling of the ball makes the movement of the inner cylinder 2211 more stable, reduces vibration and shaking, and improves the stability of the entire system.

[0026] like Figure 1-10 As shown, at least one magnetic attraction mechanism 23 is installed on the second disk 21, and the magnetic attraction mechanism 23 includes a cylinder 231, and a slide groove 232 is opened on the side wall of the cylinder 231. A partition 234 is arranged in the cylinder 231, and a screw rod 236 is sleeved in the partition 234. The screw rod 236 is threadedly connected to the partition 234, and a handle 233 is installed on one side of the screw rod 236. A rubber pad 235 is sleeved on one end of the handle 233. The height of the slide groove 232 is higher than the height of the handle 233, and a magnet block 238 is installed at the bottom end of the screw rod 236.

[0027] In the specific implementation process, when the magnetic attraction mechanism 23 is in a non-working state, the magnet block 238 is located in the cylinder 231 and does not contact the ground. The operator rotates the handle 233 to move the screw rod 236 downward along the thread of the partition 234 until the magnet block 238 extends out of the cylinder 231 and contacts the ground. When the magnet block 238 contacts the metal surface, a magnetic force is immediately generated, and the welding machine 1 is firmly adsorbed on the metal surface to increase stability. When the welding machine 1 needs to be moved, the handle 233 is rotated in the opposite direction to move the screw rod 236 upward, and the magnet block 238 is retracted into the cylinder 231 and no longer adsorbs the metal surface. The magnet block 238 can be firmly adsorbed on the metal surface to prevent the welding machine 1 from moving due to the operator pulling the welding gun, thereby improving the stability of the equipment. When working at high altitude, the magnetic attraction mechanism can effectively prevent the welding machine 1 from falling from a height due to accidental movement, thereby improving the safety of the operation. The magnetic attraction can be started or released by rotating the handle 233, and the operation is simple and quick.

[0028] like Figure 1-10 As shown, a slot 239 is provided at the bottom end of the screw rod 236 , and a rotating block 237 is fixedly connected to the top of the magnet block 238 . The rotating block 237 is disposed in the slot 239 , and the slot 239 is rotatably connected to the rotating block 237 .

[0029] In the specific implementation process, the design of the slot 239 and the rotating block 237 allows the magnet block 238 to rotate freely at the bottom end of the screw rod 236. When the handle 233 is turned, the magnet block 238 will not rotate with the rotation of the screw rod 236. The independent rotation design of the magnet block 238 reduces the friction between the magnet block and the metal surface, and prolongs the service life of the magnet block.

[0030] like Figure 1-10 As shown, a plurality of support columns 24 are installed on the top of the second disc 21 , and a third ball 25 is installed on the top of the support column 24 . The third ball 25 is rotatably connected to the support column 24 , and the third ball 25 is used to support the first disc 11 .

[0031] In the specific implementation process, the second disc 21 is fixed on the ground, the support column 24 is vertically installed on the top of the second disc 21, the third ball 25 is installed on the top of the support column 24, and the first disc 11 is placed on the third ball 25 and supported by the third ball 25. When the operator pulls the welding gun, the welding machine 1 will drive the first disc 11 to move. Since the third ball 25 is rotatably connected to the support column 24, when the first disc 11 moves, the third ball 25 will roll freely on the support column 24, reducing the friction between the first disc 11 and the support column 24. This design makes the movement of the first disc 11 smoother and reduces the jamming or resistance caused by excessive friction.

[0032] like Figure 1-10 As shown, the shape of the wire 227 is spiral.

[0033] In the specific implementation process, the spiral wire 227 has good elasticity and can be freely extended or shortened when the inner cylinder 2211 slides, without restricting the movement of the inner cylinder 2211, so that the wire 227 can adapt to the changes of different lengths and ensure the continuity and reliability of the circuit. The spiral wire 227 can effectively reduce the tensile stress caused by the movement of the welding machine 1 and avoid wire breakage or short circuit. Reducing stress can extend the service life of the wire 227 and reduce the maintenance and replacement frequency.

[0034] like Figure 1-10 As shown, at least one handle is installed on the top of the welding machine 1.

[0035] In the specific implementation process, the design of the handle allows the welding machine 1 to be easily lifted and carried, especially when the equipment needs to be frequently moved, the handle provides great convenience. The design of the handle allows the operator to hold the welding machine 1 more stably, reducing the risk of the equipment falling due to improper handling. The shape and material design of the handle can increase the friction of the grip to prevent the equipment from falling due to hand slippage.

[0036] Embodiment 2: In embodiment 1, there is still a problem that the inner cylinder 2211 cannot slide easily. Therefore, unlike embodiment 1, this embodiment includes: the bottom of the inner cylinder 2211 does not contact the second disc 21.

[0037] In the specific implementation process, a certain air gap is left between the bottom of the inner cylinder 2211 and the second disc 21, which can significantly reduce the friction between the two. This design makes the inner cylinder 2211 smoother when sliding, reducing the jamming or resistance caused by excessive friction. Due to the reduction of friction, the sliding of the inner cylinder 2211 is more sensitive, and it can respond to the movement of the welding machine 1 more quickly, thereby triggering the alarm more promptly. The absence of the bottom plate 229 and the first ball 2210 reduces potential failure points and improves the overall reliability of the system. The simplified design makes maintenance more convenient, and even if there is a problem, it can be repaired or replaced more easily.

[0038] Specifically, the working principle of the present invention is as follows: In the initial state, the welding machine 1 is fixed to the ground by the sliding mechanism 22 on the first disc 11 and the second disc 21 at the bottom. The inner cylinder 2211 in the warning mechanism 2 is supported by the third ball 25 and the first ball 2210. The design of these balls greatly reduces the friction between the inner cylinder 2211 and the ground or other supporting platforms, making the inner cylinder 2211 smoother when sliding. When the operator pulls the welding gun, the welding machine 1 will drive the inner cylinder 2211 to slide. Due to the large friction between the warning mechanism 2 and the ground, it remains relatively still and does not move with the welding machine 1. The sliding of the inner cylinder 2211 causes the first copper ring 223 and the second copper ring 2214 to contact, forming a closed circuit.

[0039] After the circuit is closed, the battery 226 supplies power to the speaker 225 through the wire 227, and the speaker 225 emits an alarm to remind the operator that the welding machine 1 has moved beyond the safe range. The spiral wire 227 has good elasticity and can be freely extended or shortened when the inner cylinder 2211 slides, ensuring the continuity and reliability of the circuit and avoiding breakage or short circuit caused by pulling. This design not only improves the response speed of the system, but also extends the service life of the wire 227 and reduces the maintenance and replacement frequency.

[0040] The magnetic attraction mechanism 23 extends the magnet block 238 by rotating the handle 233, and adsorbs it on the metal surface, thereby increasing the stability of the welding machine 1 and preventing it from falling due to accidental movement. The design of the handle allows the welding machine 1 to be easily lifted and carried, improving the convenience and safety of operation. The design of the third ball 25 and the first ball 2210 reduces friction, ensures smooth sliding of the inner cylinder 2211 and the first disc 11, and improves the overall performance and reliability of the system.

[0041] In summary, the present invention solves the problem that the existing small laser welding machine is easily pulled by the welding gun during high-altitude operation and thus falls from a high altitude, causing a safety hazard.

[0042] The above are only preferred specific implementation modes of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical solutions and inventive concepts of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
