Description

Technical Field

[0001] This invention relates to the field of laser cutting and welding technology, specifically to an integrated laser cutting and welding device for stainless steel bars. Background Technology

[0002] Stainless steel bars are made from stainless steel ingots through hot rolling or forging. According to shape, they can be roughly divided into: stainless steel round bars, stainless steel square bars, stainless steel hexagonal bars, and stainless steel semi-circular bars, etc. According to surface treatment, they can be divided into: stainless steel black bars, stainless steel acid white bars, stainless steel bright bars, and stainless steel ground bars.

[0003] An existing patent (publication number: CN119566585A) discloses an integrated three-dimensional laser cutting and welding device for irregularly shaped tubes, comprising: a base with a drive mechanism installed inside and a moving mechanism installed on the top surface; a support assembly with a motor three installed on the top of the support assembly, an adjustment plate connected to the output end of the motor three, sleeves installed on both sides of the adjustment plate, and a cutting head and a welding head respectively arranged inside the sleeves on both sides; a clamping assembly for clamping the irregularly shaped tube, and the moving mechanism for driving the clamping assembly and the irregularly shaped tube to move closer to the sleeves. The clamping assembly can clamp and rotate the irregularly shaped tube, and the moving mechanism or drive mechanism can drive the irregularly shaped tube to move. The motor three drives the adjustment plate to move the cutting head or welding head to directly above the base. Therefore, the cutting and welding of irregularly shaped tubes can be performed on the same device, thereby reducing the equipment's footprint and lowering the operating cost.

[0004] However, the above technical solution still has certain defects. During the fixing process, the outer wall of the mounting cylinder is equipped with three sets of pressure rods and pressure strips. Although it can fix the round bar, it cannot firmly fix the bar when fixing the semi-circular bar or square bar. Furthermore, manually rotating the pressure rods cannot make the number of rotations of the multiple sets of pressure rods consistent, resulting in the two sets of bars not being able to keep coaxial. Also, only one end of the mounting cylinder is equipped with a pressure rod. After the bar is fixed, the downward pressure generated by the weight of the bar away from the pressure rod end makes it impossible to fix the bar horizontally. Therefore, an integrated laser cutting and welding equipment for stainless steel bars is proposed. Summary of the Invention

[0005] Based on this, the purpose of the present invention is to provide an integrated laser cutting and welding device for stainless steel bars to solve the technical problems mentioned in the background above.

[0006] To achieve the above objectives, the present invention provides the following technical solution: an integrated laser cutting and welding device for stainless steel bars, comprising a base, two sets of fixing mechanisms at the top of the base, each set of fixing mechanisms comprising a set of fixing cylinders, a set of clamping assemblies at both ends of each set of fixing cylinders, each set of clamping assemblies comprising multiple sets of connecting arms, the connecting arms being rotatably connected to the side wall of the fixing cylinder, a connecting hole being provided at the end of the connecting arm located outside the fixing cylinder, and a connecting rod being slidably fitted onto the inner wall of the connecting hole;

[0007] The outer wall of the fixed cylinder is provided with a hydraulic assembly, which includes a first collar. Two sets of hydraulic rods are fixedly connected to the side wall of the first collar. The two sets of hydraulic rods are fixedly connected to the outer wall of the fixed cylinder. A second collar is slidably sleeved on the end of the fixed cylinder away from the first collar. Multiple sets of push-pull rods are fixedly connected between the second collar and the first collar. Multiple sets of first connecting rods are hinged to the side wall of the first collar. Multiple sets of second connecting rods are hinged to the side wall of the second collar. The ends of the first connecting rods and the second connecting rods are respectively fixedly connected to the ends of multiple sets of connecting rods.

[0008] As a preferred technical solution, a guide rod is fixedly connected to one end of the connecting arm inside the fixed cylinder. A sleeve is slidably fitted on the outer wall of the guide rod, and a support spring is fixedly fitted on the inner wall of the guide rod. The support spring is located inside the sleeve, and the end of the support spring is fixedly connected to the inner wall of the sleeve.

[0009] As a preferred technical solution, the bottom end of the sleeve is slidably connected to two sets of sliders, and the bottom end of each set of sliders is fixedly connected to a set of clamps, and the bottom end of the clamps is slidably connected to multiple sets of rubber strips.

[0010] As a preferred technical solution, the bottom end of the fixed cylinder is fixedly connected to a rotating shaft, the rotating shaft is rotatably connected to the inner wall of the base, the two ends of the rotating shaft pass through the top and bottom ends of the base respectively, the bottom end of the rotating shaft is fixedly connected to a synchronous pulley, and the outer walls of the two sets of synchronous pulleys are fitted with synchronous belts.

[0011] As a preferred technical solution, a welding and cutting mechanism is fixedly connected to the top of the base. The welding and cutting mechanism is located between two sets of fixed mechanisms. The welding and cutting mechanism includes an outer frame, which is fixedly connected to the top of the base. Multiple sets of guide wheels are fixedly connected to the inner wall of the outer frame.

[0012] As a preferred technical solution, a rotating ring abuts between multiple sets of guide wheels, a motor is fixedly connected to the side wall of the outer frame, a rubber wheel is fixedly connected to the output end of the motor, and the rubber wheel is attached to the outer wall of the rotating ring.

[0013] As a preferred technical solution, the inner wall of the rotating ring is provided with multiple sets of limiting grooves, and the inner wall of the rotating ring is slidably connected with multiple sets of sliding seats. Each set of sliding seats has a set of limiting strips slidably connected to its inner wall, and the limiting strips extend into the limiting grooves.

[0014] As a preferred technical solution, each set of sliding seats is hinged to a set of adjusting arms on its side wall, and pistons are slidably sleeved on the inner walls of the two sets of adjusting arms on the same side. The side wall of the piston is fixedly connected to an abutment rod extending to the outside of the adjusting arm.

[0015] As a preferred technical solution, the ends of the two sets of abutment rods located on the same side are hinged to a connecting seat. The connecting seat is provided with a torsion spring at the connection point with the abutment rod. A set of rollers is rotatably connected to each side of the connecting seat. A laser welding head and a laser cutting head are fixedly connected to the side walls of the two sets of connecting seats respectively.

[0016] As a preferred technical solution, the adjusting arm has a cavity at the contact position with the piston, the cavity is filled with damping oil, the inner wall of the piston has a through hole, the side wall of the piston is fixedly connected to a buffer spring, and the end of the buffer spring is fixedly connected to the inner wall of the adjusting arm.

[0017] In summary, the present invention has the following main beneficial effects:

[0018] 1. This invention uses a hydraulic rod to drive the first and second rings, so that the two sets of clamping components at both ends of the fixed cylinder can simultaneously clamp and fix the rod. There are four sets of connecting arms and four sets of chucks in the non-clamping components. The four sets of chucks move synchronously towards the center under the drive of the hydraulic rod, so that after the four sets of chucks clamp the rod, the rod is located at the center of the fixed cylinder. This makes the two sets of rods to be welded coaxial after being fixed inside the two sets of fixed cylinders. Since there is a set of clamping components at each end of the fixed cylinder, the rod is fixed more stably, thereby avoiding the rod from tilting after being fixed and keeping the rod in a horizontal state, making subsequent welding more convenient.

[0019] 2. This invention uses a hydraulic rod to rotate the connecting arm, causing the clamps to fit against the outer wall of the bar. When clamping square or hexagonal bars, the slider can slide at the end of the sleeve, allowing the two sets of clamps at the end of each sleeve to fit more closely against the surface of the bar. After the clamps fit against the surface of the bar, as the hydraulic rod continues to contract, the clamps in the two sets of fixing mechanisms can push the two sets of bars against each other, preventing gaps at the weld joints between the bars during welding and avoiding welding problems. During cutting, by rotating the two sets of fixing cylinders, the clamps in the two sets of fixing cylinders can apply a push to both ends of the bar after fitting against the surface of the bar, preventing slag from sticking to the cut part of the bar during cutting.

[0020] 3. This invention pushes the sliding seat to slide inside the rotating ring, causing the two sets of sliding seats on the same side to push the adjusting arm to flip, thereby bringing the connecting seat closer to the bar and causing the roller to fit against the outer wall of the bar. This also compresses the buffer spring, and the rebound force of the buffer spring ensures that the roller always fits against the outer wall of the bar during the rotation of the rotating ring, and that the distance between the connecting seat and the bar remains consistent. This ensures that the distance between the laser welding head or laser cutting head and the bar remains consistent, thereby guaranteeing the efficiency and quality of the bar during welding or cutting.

[0033] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0034] The embodiments of the present invention will now be described.

[0035] A laser cutting and welding integrated device for stainless steel bars, such as Figures 1 to 10 As shown, the device includes a base 1, and two sets of fixing mechanisms 2 are provided at the top of the base 1. Each set of fixing mechanisms 2 includes a set of fixing cylinders 201. Each set of fixing cylinders 201 has a set of clamping components 205 at both ends. Each set of clamping components 205 includes multiple sets of connecting arms 2051. The connecting arms 2051 are rotatably connected to the side wall of the fixing cylinder 201. A connecting hole 2052 is opened at one end of the connecting arm 2051 located outside the fixing cylinder 201. A connecting rod 2059 is slidably sleeved on the inner wall of the connecting hole 2052.

[0036] A hydraulic assembly 206 is provided on the outer wall of the fixed cylinder 201. The hydraulic assembly 206 includes a first collar 2061. Two sets of hydraulic rods 2062 are fixedly connected to the side wall of the first collar 2061. The two sets of hydraulic rods 2062 are fixedly connected to the outer wall of the fixed cylinder 201. A second collar 2064 is slidably sleeved on the end of the fixed cylinder 201 away from the first collar 2061. Multiple sets of push-pull rods 2063 are fixedly connected between the second collar 2064 and the first collar 2061. Multiple sets of first connecting rods 2065 are hinged to the side wall of the first collar 2061. Multiple sets of second connecting rods 2066 are hinged to the side wall of the second collar 2064. The ends of the first connecting rods 2065 and the second connecting rods 2066 are respectively fixedly connected to the ends of multiple sets of connecting rods 2059.

[0037] At the welding point, two sets of rods need to be inserted into the two sets of fixed cylinders 201 respectively, so that the welding point of the two sets of rods is located inside the rotating ring 303, and the welding point is aligned with the laser welding head. During cutting, the rods need to be passed through the two sets of fixed cylinders 201, so that the cutting point is aligned with the laser cutting head. After the rods are inserted into the fixed cylinders 201, the hydraulic rod 2062 retracts, causing the hydraulic rod 2062 to drive the first collar 2061 to slide on the outer wall of the fixed cylinder 201. During the sliding of the first collar 2061, it pushes the push-pull rod 2063, which in turn pushes the second collar 2064, causing the second collar 2064 to slide. During the sliding of the first collar 2061 and the second collar 2064, the first collar 2061 pulls multiple sets of first connecting rods 2065, and the second collar 2064 pushes multiple sets of second connecting rods 2066, so that the first connecting rods 2065 and the second connecting rods 2066 respectively push multiple sets of connecting rods 205. 9. This causes multiple sets of connecting arms 2051 to rotate simultaneously. During the rotation of the connecting arms 2051, the guide rod 2053 rotates, causing the sleeve 2054 to rotate, and the sleeve 2054 to rotate the chuck 2057. During the above process, the distance between the multiple sets of chucks 2057 gradually approaches, thereby clamping the bar. The two sets of clamping components 205 on the same fixed cylinder 201 simultaneously clamp and fix the bar, improving the stability of the bar after it is clamped. After the bar is fixed, it is coaxial with the central axis of the fixed cylinder 201. When the chuck 2057 contacts the square bar or hexagonal bar, the clamping force causes the chuck 2057 to drive the slider 2056 to slide, causing the chuck 2057 to rotate at a certain angle. This allows the chuck 2057 to fit more firmly against the surface of the bar, thus allowing the chuck 2057 to better adapt to the outer wall shape of the square bar or hexagonal bar.

[0038] Please refer to this carefully. Figures 1 to 4One end of the connecting arm 2051, located inside the fixed cylinder 201, is fixedly connected to a guide rod 2053. A sleeve 2054 is slidably fitted on the outer wall of the guide rod 2053. A support spring 2055 is fixedly fitted on the inner wall of the guide rod 2053. The support spring 2055 is located inside the sleeve 2054, and its end is fixedly connected to the inner wall of the sleeve 2054. Two sets of sliders 2056 are slidably connected to the bottom end of the sleeve 2054. A set of clamps 2057 is fixedly connected to the bottom end of each set of sliders 2056. Multiple sets of rubber strips 2058 are slidably connected to the bottom end of the clamps 2057. A rotating shaft 202 is fixedly connected to the bottom end of the fixed cylinder 201. The rotating shaft 202 is rotatably connected to the inner wall of the base 1. The two ends of the rotating shaft 202 pass through the top and bottom ends of the base 1, respectively. A synchronous wheel 203 is fixedly connected to the bottom end of the rotating shaft 202. A synchronous belt 204 is fitted on the outer wall of the two sets of synchronous wheels 203.

[0039] During welding, the multiple sets of chucks 2057 rotate towards the welding point of the two sets of bars. After the chucks 2057 are in contact with the surface of the bars, the hydraulic rod 2062 continues to rotate the chucks 2057. At this time, the distance between the multiple sets of chucks 2057 cannot be reduced further, causing the sleeve 2054 to be pushed, thereby compressing the support spring 2055. In this process, the chucks 2057 generate a horizontal pushing force on the bars, causing the two sets of bars to be pushed together during welding, avoiding gaps at the welding point of the two sets of bars. When it is necessary to cut the bars, one set of fixed cylinders 201 is rotated 180 degrees, causing the fixed cylinders 201 to drive the rotating shaft 202, which in turn drives a set of synchronous pulleys 203 to rotate. During the rotation of one set of synchronous pulleys 203, the synchronous belt 204 causes another set of synchronous pulleys 203 to rotate, thereby causing another set of rotating shafts 202 to rotate, driving another set of fixed cylinders 2054 to rotate. 01 rotates, causing both sets of fixed cylinders 201 to rotate simultaneously. The bar is then passed through the two sets of fixed cylinders 201. The first ring 2061 is pulled by the hydraulic rod 2062, causing multiple sets of chucks 2057 to adhere to the outer wall of the bar and clamp it. At this time, the multiple sets of chucks 2057 are rotated in the opposite direction to the two ends of the bar. After the chucks 2057 adhere to the surface of the bar, they will apply a horizontal thrust to the two ends of the bar. This causes the slag at the cutting point to adhere to the cutting point during the cutting process. After the cutting is completed, the horizontal thrust on the bar towards both ends causes the cut bar to completely separate from the cutting point to both ends. This eliminates the need for manual tapping of the cutting point after cutting to promote the separation of the bar. In addition, the rubber strip 2058 at the bottom of the chuck 2057 can increase the friction between the chuck 2057 and the bar and can also prevent the chuck 2057 from scratching the outer wall of the bar.

[0040] Please refer to this carefully. Figures 7 to 10A welding and cutting mechanism 3 is fixedly connected to the top of the base 1. The welding and cutting mechanism 3 is located between two sets of fixed mechanisms 2. The welding and cutting mechanism 3 includes an outer frame 301, which is fixedly connected to the top of the base 1. Multiple sets of guide wheels 302 are fixedly connected to the inner wall of the outer frame 301. A rotating ring 303 abuts between the multiple sets of guide wheels 302. A motor 4 is fixedly connected to the side wall of the outer frame 301. A rubber wheel 5 is fixedly connected to the output end of the motor 4. The rubber wheel 5 is in contact with the outer wall of the rotating ring 303. Multiple sets of limiting grooves 304 are opened on the inner wall of the rotating ring 303. Multiple sets of sliding seats 305 are slidably connected to the inner wall of each set of sliding seats 305. A set of limiting strips 306 are slidably connected to the inner wall of each set of sliding seats 305. The limiting strips 306 extend into the limiting grooves 304. An adjusting arm 3 is hinged to the side wall of each set of sliding seats 305. 07. Pistons 308 are slidably sleeved on the inner walls of two sets of adjusting arms 307 located on the same side. Abutment rod 309 extending to the outside of the adjusting arm 307 is fixedly connected to the side wall of the piston 308. Connecting seats 310 are hinged to the ends of the two sets of abutment rods 309 located on the same side. A torsion spring is provided at the connection between the connecting seat 310 and the abutment rod 309. A set of rollers 311 are rotatably connected to both sides of the connecting seat 310. A laser welding head and a laser cutting head are fixedly connected to the side walls of the two sets of connecting seats 310 respectively. A cavity 312 is opened at the contact position between the adjusting arm 307 and the piston 308. Damping oil is provided inside the cavity 312. A through hole 314 is opened through the inner wall of the piston 308. A buffer spring 313 is fixedly connected to the side wall of the piston 308. The end of the buffer spring 313 is fixedly connected to the inner wall of the adjusting arm 307.

[0041] By pushing the limiting strip 306 to slide on the inner wall of the sliding seat 305, the sliding seat 305 slides out from inside the limiting groove 304. At this time, pushing the sliding seat 305 to slide on the inner wall of the rotating ring 303, and controlling the distance between the two sets of sliding seats 305 on the same side, the two sets of sliding seats 305 push the adjusting arm 307, thereby causing the connecting seat 310 to move closer to the welding or cutting point of the bar, thereby causing the laser welding head or laser cutting head to move closer to the bar, and the connecting seat 310 is connected by the abutment rod 309. The torsion spring's rotational force on the adjusting arms 307 causes the limiting strip 306 inside the sliding seat 305 to fit tightly against the inner wall of the limiting groove 304, thus preventing the limiting strip 306 from sliding out of the limiting groove 304 without manual pushing. As the connecting seat 310 approaches the bar, it drives the roller 311 to fit against the surface of the bar. As the motor 4 drives the rubber wheel 5 to rotate, the rubber wheel 5 pushes the rotating ring 303 to rotate, causing the rotating ring 303 to drive the connecting seat 310 to rotate, thereby causing the two sets of connecting seats 310 to rotate. 10 rotates around the outside of the bar, causing roller 311 to roll against the outer wall of the bar. When roller 311 rolls to a protrusion on the outside of the bar, it is pushed, causing connecting seat 310 to push abutment rod 309. This causes piston 308 to slide inside adjusting arm 307, thereby compressing buffer spring 313. When roller 311 slides past the protrusion on the outside of the bar, buffer spring 313 rebounds, pushing piston 308 back to its original position. This ensures that roller 311 always stays against the outer wall of the bar, allowing laser cutting to proceed smoothly. The distance between the cutting head or laser welding head and the outer wall of the bar remains constant. During the sliding process of the piston 308, the damping oil is squeezed and flows through the through hole 314, which causes the piston 308 to be resisted during the sliding process. This buffers the rebound force of the buffer spring 313, reduces the impact force generated by the rebound of the buffer spring 313, and ensures that the rebound force of the buffer spring 313 is applied to the outer wall of the bar through the roller 311 without excessive jumping of the roller 311, thereby improving the stability during welding or cutting.

[0042] In use, the hydraulic rod 2062 drives the first ring 2061 and the second ring 2064, so that the two sets of clamping components 205 at both ends of the fixed cylinder 201 simultaneously clamp and fix the rod. There are four sets of connecting arms 2051 and four sets of chucks 2057 in the part without clamping components 205. The four sets of chucks 2057 move synchronously towards the center under the drive of the hydraulic rod 2062, so that after the four sets of chucks 2057 clamp the rod, the rod is located at the center of the fixed cylinder 201. This makes the two sets of rods to be welded coaxial after being fixed inside the two sets of fixed cylinders 201. Since there is a set of clamping components 205 at each end of the fixed cylinder 201, the rod is fixed more stably, thus avoiding tilting after the rod is fixed and keeping the rod in a horizontal state, making subsequent welding more convenient. The parts of this device not mentioned are the same as or can be implemented using existing technology.
