Description

Technical Field

[0001] The invention relates to the technical field of laser cutting and welding, and in particular to integrated laser cutting and welding equipment for stainless steel bars. Background Art

[0002] Stainless steel bars are made of stainless steel ingots through hot rolling or forging. According to their shapes, they can be roughly divided into: stainless steel round bars, stainless steel square bars, stainless steel hexagonal bars and stainless steel semi-round 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 special-shaped tubes, comprising: a base, a driving mechanism installed inside the base, and a moving mechanism installed on the top surface; a support assembly, a motor three is installed on the top of the support assembly, an output end of the motor three is connected to an adjustment plate, sleeves are installed on both sides of the adjustment plate, and a cutting head and a welding head are respectively arranged inside the sleeves on both sides, a clamping assembly is used to clamp the special-shaped tube, and the moving mechanism is used to drive the clamping assembly and the special-shaped tube to move close to the sleeve, which can clamp and rotate the special-shaped tube through the clamping assembly, use the moving mechanism or the driving mechanism to drive the special-shaped tube to move, and drive the adjusting plate by the motor three to move the cutting head or the welding head to just above the base, so that the cutting and welding of the special-shaped tube can be carried out on the same device, thereby reducing the space occupied by the equipment and reducing the use cost.

[0004] However, the above technical scheme still has certain defects. During the fixing process of the above technical scheme, three groups of pressure rods and pressure strips are arranged on the outer wall of the mounting tube. Although the round rod can be fixed, the semi-circular rod or square rod cannot be firmly fixed. Moreover, the number of turns of multiple groups of pressure rods cannot be consistent by manually rotating the pressure rods, resulting in that the two groups of rods cannot remain coaxial. Moreover, the pressure rod is only arranged at one end of the mounting tube.

[0033] The following will be combined with the accompanying drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

[0034] The following describes an embodiment of the present invention based on its overall structure.

[0035] An integrated laser cutting and welding device for stainless steel bars, such as Figures 1 to 10 As shown, it includes a base 1, and two sets of fixing mechanisms 2 are arranged on the top of the base 1, each set of fixing mechanisms 2 includes a set of fixing cylinders 201, and a set of clamping components 205 are arranged at both ends of each set of fixing cylinders 201, and each set of clamping components 205 includes a plurality of connecting arms 2051, and the connecting arms 2051 are rotatably connected to the side walls of the fixing cylinders 201, and a connecting hole 2052 is opened at one end of the connecting arm 2051 located outside the fixing cylinder 201, and 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, and the hydraulic assembly 206 includes a first ring 2061, and two groups of hydraulic rods 2062 are fixedly connected to the side wall of the first ring 2061, and the two groups of hydraulic rods 2062 are fixedly connected to the outer wall of the fixed cylinder 201. A second ring 2064 is slidably sleeved on the end of the fixed cylinder 201 away from the first ring 2061, and multiple groups of push-pull rods 2063 are fixedly connected between the second ring 2064 and the first ring 2061. Multiple groups of first connecting rods 2065 are hinged to the side wall of the first ring 2061, and multiple groups of second connecting rods 2066 are hinged to the side wall of the second ring 2064. The ends of the first connecting rods 2065 and the second connecting rods 2066 are respectively fixedly connected to the ends of multiple groups of connecting rods 2059.

[0037] At the welding place, the two groups of rods need to be respectively extended into the two groups of fixed tubes 201, so that the welding place of the two groups of rods is located inside the rotating ring 303, so that the welding place is aligned with the laser welding head. When cutting, the rods need to pass through the two groups of fixed tubes 201, so that the part to be cut is aligned with the laser cutting head. After the rods are inserted into the fixed tube 201, the hydraulic rod 2062 is contracted, so that the hydraulic rod 2062 drives the first ring 2061 to slide on the outer wall of the fixed tube 201. During the sliding process of the first ring 2061, the push-pull rod 2063 is pushed, so that the push-pull rod 2063 pushes the second ring 2064, so that the second ring 2064 slides. During the sliding process of the first ring 2061 and the second ring 2064, the first ring 2061 pulls multiple groups of first connecting rods 2065, and the second ring 2064 pushes multiple groups of second connecting rods 2066, so that the first connecting rod 2065 and the second connecting rod 2066 respectively push the multiple groups of connecting rods 205 9, so that multiple groups of connecting arms 2051 are flipped at the same time, and during the flipping process of the connecting arms 2051, the guide rod 2053 is driven to flip, so that the guide rod 2053 drives the sleeve 2054 to flip, and the sleeve 2054 drives the chuck 2057 to flip. In the above process, the distances between the multiple groups of chucks 2057 are gradually close, so that the rod is clamped, and the two groups of clamping assemblies 205 on the same fixed cylinder 201 clamp and fix the rod at the same time, which improves the stability of the rod after being clamped, and makes the rod coaxial with the central axis of the fixed cylinder 201 after being fixed. When the chuck 2057 contacts the square rod or the hexagonal rod, the clamping force makes the chuck 2057 drive the slider 2056 to slide, so that the chuck 2057 rotates at a certain angle, so that the chuck 2057 can fit the surface of the rod more firmly, so that the chuck 2057 can better adapt to the outer wall shape of the square rod or the hexagonal rod.

[0038] Please refer to Figures 1 to 4, one end of the connecting arm 2051 located inside the fixed cylinder 201 is fixedly connected to a guide rod 2053, the outer wall of the guide rod 2053 is slidably sleeved with a sleeve 2054, the inner wall of the guide rod 2053 is fixedly sleeved with a support spring 2055, the support spring 2055 is located inside the sleeve 2054, the end of the support spring 2055 is fixedly connected to the inner wall of the sleeve 2054, the bottom end of the sleeve 2054 is slidably connected to two groups of sliders 2056, the bottom end of each group of sliders 2056 is respectively fixedly connected to a group of chucks 2057, and the bottom end of the chuck 2057 is slidably connected to multiple groups of rubber strips 2058, the bottom end of the fixed cylinder 201 is fixedly connected to a rotating shaft 202, the rotating shaft 202 is rotatably connected to the inner wall of the base 1, the two ends of the rotating shaft 202 respectively pass through the top and bottom ends of the base 1, the bottom end of the rotating shaft 202 is fixedly connected to a synchronous wheel 203, and the outer walls of the two groups of synchronous wheels 203 are sleeved with synchronous belts 204.

[0039] During welding, the multiple sets of chucks 2057 are flipped in the direction toward the welding point of the two sets of bars. After the chucks 2057 are attached to the surface of the bars, the hydraulic rod 2062 continues to drive the chucks 2057 to flip. At this time, the spacing between the multiple sets of chucks 2057 cannot be further reduced, so that the sleeve 2054 is pushed, thereby compressing the support spring 2055, and in this process, the chucks 2057 produce a horizontal driving force on the bars, so that the two sets of bars are pushed to fit each other during welding, avoiding the occurrence of a gap in 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, so that the fixed cylinders 201 drive the rotating shaft 202, so that the rotating shaft 202 drives a set of synchronous wheels 203 to rotate. During the rotation of one set of synchronous wheels 203, the synchronous belt 204 causes another set of synchronous wheels 203 to rotate, thereby causing another set of rotating shafts 202 to rotate, driving another set of fixed cylinders 2 01 rotates, thereby making the two sets of fixed cylinders 201 rotate at the same time, and then the rod passes through the two sets of fixed cylinders 201, and then the hydraulic rod 2062 is used to pull the first ring 2061, so that the multiple sets of chucks 2057 are attached to the outer wall of the rod to clamp the rod, but at this time the multiple sets of chucks 2057 are flipped towards the two ends of the rod respectively. After the chucks 2057 are attached to the surface of the rod, a horizontal thrust toward the two ends of the rod is applied to the rod, so that during the cutting process, the slag at the cutting point adheres to the cutting point, and after the cutting is completed, the horizontal thrust toward the two ends on the rod makes the cut rod completely separated from the cutting point to the two ends, eliminating the step of manually knocking the cutting point after cutting to promote the separation of the rod, and the rubber strip 2058 at the bottom end of the chuck 2057 can increase the friction between the chuck 2057 and the rod, and can also prevent the chuck 2057 from scratching the outer wall of the rod.

[0040] Please refer to Figures 7 to 10The top of the base 1 is fixedly connected with a welding and cutting mechanism 3, which is located between the two sets of fixing mechanisms 2. The welding and cutting mechanism 3 includes an outer frame 301, which is fixedly connected to the top of the base 1, and the inner wall of the outer frame 301 is fixedly connected with multiple sets of guide wheels 302, and a rotating ring 303 is abutted between the multiple sets of guide wheels 302. The side wall of the outer frame 301 is fixedly connected with a motor 4, and the output end of the motor 4 is fixedly connected with a rubber wheel 5, which is attached to the outer wall of the rotating ring 303. The inner wall of the rotating ring 303 is provided with multiple sets of limiting grooves 304, and the inner wall of the rotating ring 303 is slidably connected with multiple sets of sliding seats 305, and the inner wall of each set of sliding seats 305 is respectively slidably connected with a set of limiting strips 306, and the limiting strips 306 extend into the limiting grooves 304. The side walls of each set of sliding seats 305 are respectively hinged with a set of adjusting arms 3 07. The inner wall sliding sleeves of the two groups of regulating arms 307 located on the same side are provided with pistons 308. The side walls of the pistons 308 are fixedly connected with abutment rods 309 extending to the outside of the regulating arms 307. The ends of the two groups of abutment rods 309 located on the same side are hinged with connecting seats 310. The connecting seats 310 are provided with torsion springs at the connection with the abutment rods 309. A group of rollers 311 are rotatably connected to the two sides of the connecting seats 310. The side walls of the two groups of connecting seats 310 are fixedly connected with laser welding heads and laser cutting heads respectively. The regulating arms 307 are provided with cavities 312 at the contact positions with the pistons 308. Damping oil is provided inside the cavities 312. A through hole 314 is penetrated through the inner wall of the piston 308. The side walls of the pistons 308 are fixedly connected with buffer springs 313. The ends of the buffer springs 313 are fixedly connected to the inner wall of the regulating arms 307.

[0041] By pushing the limit bar 306 to slide on the inner wall of the sliding seat 305, the sliding seat 305 slides out from the inside of the limit groove 304. At this time, the sliding seat 305 is pushed to slide on the inner wall of the rotating ring 303. By controlling the distance between the two groups of sliding seats 305 on the same side, the two groups of sliding seats 305 push the adjustment arm 307, so that the connecting seat 310 is close to the welding or cutting part of the rod, so that the laser welding head or laser cutting head is close to the rod, and the connection between the abutment rod 309 and the connecting seat 310 is The turning force between the torsion spring and the adjusting arm 307 makes the limiting strip 306 inside the sliding seat 305 fit tightly against the inner wall of the limiting groove 304, so that the limiting strip 306 will not slide out of the limiting groove 304 without human push. When the connecting seat 310 approaches the rod, the roller 311 is driven to fit against the surface of the rod. When the motor 4 drives the rubber wheel 5 to rotate, the rubber wheel 5 drives the rotating ring 303 to rotate, so that the rotating ring 303 drives the connecting seat 310 to rotate, so that the two sets of connecting seats 310 are connected. 10 rotates around the outside of the rod, so that the roller 311 is in contact with the outer wall of the rod and rolls. When the roller 311 rolls to the protrusion on the outside of the rod, the roller 311 is pushed, so that the connecting seat 310 pushes the abutment rod 309, so that the piston 308 slides inside the adjustment arm 307, thereby compressing the buffer spring 313. When the roller 311 slides over the protrusion on the outside of the rod, the buffer spring 313 rebounds and pushes the piston 308 to reset, so that the roller 311 is always in contact with the outer wall of the rod, so that the laser cutting The distance between the cutting head or laser welding head and the outer wall of the rod is always consistent. During the sliding process of the piston 308, the damping oil is squeezed to flow through the through hole 314, so that the piston 308 is subjected to resistance during the sliding process, so that the rebound force of the buffer spring 313 is buffered to a certain extent, and the impact force generated by the rebound of the buffer spring 313 is reduced. After the rebound force of the buffer spring 313 is applied to the outer wall of the rod through the roller 311, the roller 311 will not have unnecessary jumping, thereby improving the stability during welding or cutting.

[0042] When in use, the first ring 2061 and the second ring 2064 are driven by the hydraulic rod 2062, so that the two groups of clamping assemblies 205 at both ends of the fixed cylinder 201 clamp and fix the rod at the same time, and there are four groups of connecting arms 2051 and four groups of chucks 2057 in the clamping assembly 205, and the four groups of chucks 2057 move synchronously to the middle under the drive of the hydraulic rod 2062, so that after the four groups of chucks 2057 clamp the rod, the rod is located at the center of the fixed cylinder 201, so that after the two groups of rods to be welded are fixed inside the two groups of fixed cylinders 201, they are in a coaxial state, and because there is a group of clamping assemblies 205 at each end of the fixed cylinder 201, the rod is fixed more firmly, thereby avoiding tilting of the rod after being fixed, making the rod in a horizontal state, making subsequent welding more convenient, and the parts not involved in the device are the same as the prior art or can be implemented by the prior art.
