Description

Technical Field

[0001] This invention relates to the field of laser cutting machine technology, and more specifically, to a multifunctional tube-shaped laser cutting machine. Background Technology

[0002] A laser cutting machine is a device that uses a high-energy laser beam focused by an optical system and combined with a CNC worktable to instantly melt, vaporize, or ablate metal and non-metal sheets, and then uses auxiliary gas to blow away the molten slag to complete the cutting. Its laser source is mostly fiber optic or CO2, with power ranging from hundreds of watts to tens of thousands of watts. It can process carbon steel, stainless steel, aluminum, copper, and titanium alloys, and can also cut acrylic, wood, ceramics, and composite materials. It produces narrow kerfs, small heat-affected zones, and bright edges, with a cut width of less than 0.1mm and dimensional accuracy of ±0.03mm. Its speed is several times faster than traditional punching and shearing, requires no molds, and allows for one-click switching of patterns, making it suitable for prototyping, mass production, and flexible manufacturing.

[0003] Laser cutting machines can cut steel profiles and pipes, but when faced with large steel profiles and pipes, most existing laser cutting machines are difficult to adapt to simultaneously. Conventionally, multiple machines are used to cut large steel profiles and pipes separately, which requires a lot of space and results in high site and equipment costs. Summary of the Invention

[0004] In view of the shortcomings of the existing technology, the purpose of this invention is to provide a multifunctional tube-shaped laser cutting machine.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a multifunctional tube-shaped laser cutting machine, comprising a cutting machine slide rail, a cantilever seat slidably connected to the cutting machine slide rail, one end of the cantilever seat away from the cutting machine slide rail being suspended, a robotic arm mounted on the cantilever seat, a laser head mounted on the end effector of the robotic arm, and a steel profile support frame and a tube support platform mounted on one side of the cutting machine slide rail, the steel profile support frame being used to support steel profile workpieces, and the tube support platform being used to support tube-shaped workpieces; The pipe support platform includes a base, a pneumatic chuck, a laser chuck, a feeding mechanism, a follow-up support mechanism, and a discharging mechanism. The base is mounted on one side of the cutting machine slide rail. Pneumatic chucks are slidably connected to both ends of the base. A laser chuck is installed on the base and is located between the two pneumatic chucks. The feeding mechanism, the follow-up support mechanism, and the unloading mechanism are all mounted on the base. The feeding mechanism is used to transport the workpiece to the base, the follow-up support mechanism is used to lift and position the workpiece on the base, and the unloading mechanism is used to provide support for the cut workpiece.

[0006] A further technical solution of this application: a protective plate is fixedly connected to the end of the cantilever seat away from the cutting machine slide rail.

[0007] A further technical solution of this application: The feeding mechanism includes legs, sprockets and chains. Multiple legs are provided and all are fixedly connected to the base. Each leg has a sprocket rotatably connected to both ends. The two sprockets on each leg are connected by chain drive.

[0008] A further technical solution of this application: the feeding mechanism also includes a motor and a horizontal shaft. The motor is mounted on the base, and the output shaft of the motor is connected to the horizontal shaft through a transmission mechanism. The sprocket at one end of each of the support legs is fixedly connected to the horizontal shaft.

[0009] A further technical solution of this application: multiple follow-up support mechanisms are provided and all are set on the base. Each follow-up support mechanism includes a lifting seat, a roller, a transverse seat and a clamping roller. The lifting seat is slidably connected to the base. A roller is rotatably connected to the lifting seat. Two transverse seats are slidably connected to the lifting seat. Clamping rollers are rotatably connected to the two transverse seats respectively.

[0010] A further technical solution of this application: each of the transverse shift seats is slidably connected with multiple guide rods, the upper ends of the multiple guide rods are fixedly connected to the top plate, and the clamping roller is rotatably connected to the top plate.

[0011] A further technical solution of this application: the feeding mechanism is provided in multiple ways and is all arranged on the base. Each feeding mechanism includes a pallet and a support roller. The pallet is hinged to the base and multiple support rollers are rotatably connected to the pallet.

[0012] Compared with the prior art, the present invention has the following beneficial effects: 1. The steel profile support frame provides stable support for steel profile workpieces. A cantilever mount moves the robotic arm and laser head along the cutting machine's slide rail to one side of the steel profile support frame, allowing the laser head to cut the steel profile workpiece. Similarly, the pipe support platform provides stable support for pipe workpieces. A cantilever mount moves the robotic arm and laser head along the cutting machine's slide rail to one side of the pipe support platform, allowing the laser head to cut the pipe workpiece. This allows for the cutting of large-sized steel profiles and pipes on the same machine, requiring less space and resulting in lower site and equipment costs. 2. The laser, chiller, electrical box and other accessories required for the operation of the laser head are all installed on the cantilever base, which acts as a counterweight, so that the cantilever base with one end suspended can remain stable. The suspended end of the cantilever base is more convenient for loading and unloading materials.

[0019] Reference Figures 1 to 8 In one embodiment of this application, a multifunctional tube-shaped laser cutting machine includes a cutting machine slide rail 1, a cantilever seat 2 slidably connected to the cutting machine slide rail 1, one end of the cantilever seat 2 away from the cutting machine slide rail 1 being suspended, a robotic arm 3 mounted on the cantilever seat 2, a laser head mounted on the end effector of the robotic arm 3, and a steel support frame 4 and a tube support platform 5 mounted on one side of the cutting machine slide rail 1. The steel support frame 4 is used to support steel-shaped workpieces, and the tube support platform 5 is used to support tube-shaped workpieces. like Figure 1 and Figure 5 The laser, chiller, electrical box and other accessories required for the operation of the laser head all use existing technology, which will not be described in detail here. The robotic arm 3 can drive the laser head to move in multiple directions. Laser cutting replaces traditional plasma cutting and flame cutting. Laser cutting offers high precision, narrow kerf, and high speed. It requires no preheating or secondary processing, produces smooth cuts without slag, is applicable to a wide range of materials, has lower operating costs, is more environmentally friendly, and has superior overall performance compared to plasma and flame cutting. The cantilever 2 is driven by existing technology, such as using gears and racks to drive the cantilever 2 to slide along the cutting machine slide rail 1. This will not be elaborated here. The cantilever 2 can then drive the robotic arm 3 and the laser head to move along the cutting machine slide rail 1. Furthermore, the laser, chiller, electrical box and other accessories required for the operation of the laser head are all installed on the cantilever 2, which serves as a counterweight, so that the cantilever 2, which is suspended at one end, can also remain stable. The suspended end of the cantilever 2 is more convenient for loading and unloading materials. The steel support frame 4 is a fixed bracket welded from metal. It provides stable support for steel-type workpieces. The cantilever seat 2 drives the robotic arm 3 and laser head to move along the cutting machine slide rail 1 to one side of the steel support frame 4, whereby the laser head can cut the steel-type workpieces. The pipe support platform 5 provides stable support for pipe-type workpieces. The cantilever seat 2 drives the robotic arm 3 and laser head to move along the cutting machine slide rail 1 to one side of the pipe support platform 5, whereby the laser head can cut the pipe-type workpieces. Thus, large-sized steel-type and pipe-type workpieces can be cut on the same machine, requiring less space and resulting in lower site and equipment costs.

[0020] The pipe support platform 5 includes a base 6, a pneumatic chuck 7, a laser chuck 8, a feeding mechanism, a follow-up support mechanism, and a unloading mechanism. The base 6 is mounted on one side of the cutting machine slide rail 1. Pneumatic chucks 7 are slidably connected to both ends of the base 6. A laser chuck 8 is installed on the base 6 and is located between the two pneumatic chucks 7. The pneumatic chucks 7 and the laser chuck 8 are used to clamp and feed pipe-type workpieces. The feeding mechanism, the follow-up support mechanism, and the unloading mechanism are all mounted on the base 6. The feeding mechanism is used to transport the workpiece to the base 6, the follow-up support mechanism is used to lift and position the workpiece on the base 6, and the unloading mechanism is used to provide support for the cut workpiece.

[0021] In a preferred embodiment of this application, a protective plate 9 is fixedly connected to the end of the cantilever bracket 2 away from the cutting machine slide rail 1, such as... Figure 5 The guard plate 9 provides protection for workers and blocks the splash of cutting sparks.

[0022] As a preferred embodiment of this application, the feeding mechanism includes a support leg 10, a sprocket and a chain 11. Multiple support legs 10 are provided and are all fixedly connected to the base 6. Each support leg 10 has a sprocket rotatably connected to both ends. The two sprockets on each support leg 10 are connected by the chain 11.

[0023] As a preferred embodiment of this application, the feeding mechanism further includes a motor 12 and a horizontal shaft 13. The motor 12 is mounted on the base 6, and the output shaft of the motor 12 is connected to the horizontal shaft 13 through a transmission mechanism. The sprocket at one end of each of the support legs 10 is fixedly connected to the horizontal shaft 13. like Figure 3 and Figure 4The motor 12 can drive the horizontal shaft 13 to rotate through the transmission mechanism. The transmission mechanism adopts existing technology, such as synchronous pulleys, synchronous belts, or sprockets and chains, which will not be described in detail here. The horizontal shaft 13 can drive the sprocket at one end of the support leg 10 to rotate. With the support of the sprockets at both ends of the support leg 10, the chain 11 on the support leg 10 can be driven to rotate. During loading, the tubular workpieces are simply placed on multiple chains 11, which then transport the workpieces to the top of multiple follow-up support mechanisms.

[0024] As a preferred embodiment of this application, multiple follower support mechanisms are provided and are all arranged on the base 6. Each follower support mechanism includes a lifting seat 14, a roller 15, a transverse seat 16 and a clamping roller 17. The lifting seat 14 is slidably connected to the base 6. The roller 15 is rotatably connected to the lifting seat 14. Two transverse seats 16 are slidably connected to the lifting seat 14. Clamping rollers 17 are rotatably connected to the two transverse seats 16 respectively. like Figure 7 The lifting seat 14 can be slidably connected to the base 6 via a slide rail, and the transverse seat 16 can also be slidably connected to the lifting seat 14 via a slide rail. The movement of both the lifting seat 14 and the transverse seat 16 can be driven by an electric cylinder. The driving methods all adopt existing technologies, which will not be described in detail here.

[0025] In a preferred embodiment of this application, each of the transverse shift seats 16 is slidably connected with a plurality of guide rods 18, the upper ends of the plurality of guide rods 18 are fixedly connected to the top plate 19, and the clamping roller 17 is rotatably connected to the top plate 19. like Figure 7 Multiple guide rods 18 can be raised and lowered by an electric cylinder, thereby driving the clamping rollers 17 to rise and fall through the top plate 19; like Figure 6 and Figure 7 Before the feeding mechanism conveys the workpiece above the multiple follower support mechanisms, all components of the follower support mechanisms are below the height of the chain 11. After the workpiece is conveyed above the multiple follower support mechanisms, the lifting seat 14 rises, causing the roller 15 to lift the workpiece, and the two clamping rollers 17 on the lifting seat 14 also rise, so that the workpiece is located between the two clamping rollers 17. Then the two transverse seats 16 move closer to each other, and the workpiece can be clamped and positioned by the two clamping rollers 17. At this time, the workpiece is located between the pneumatic chuck 7 of the laser chuck 8. The pneumatic chuck 7 and the laser chuck 8 can clamp and feed the tubular workpiece for cutting. After the pneumatic chuck 7 and laser chuck 8 clamp the workpiece, the follow-up support mechanism descends and resets.

[0026] As a preferred embodiment of this application, the feeding mechanism is provided in multiple ways and is all provided on the base 6. Each feeding mechanism includes a pallet 20 and a support roller 21. The pallet 20 is hinged to the base 6, and multiple support rollers 21 are rotatably connected to the pallet 20. Figure 6 and Figure 8 An electric cylinder is installed at the bottom of the pallet 20. The electric cylinder supports the pallet 20 and can drive the pallet 20 to rotate around its hinge axis, thereby changing the tilt angle of the pallet 20. The cut workpiece will fall onto multiple pallets 20, allowing the workpiece to slide down along multiple tilted pallets 20 to complete the unloading. Multiple support rollers 21 can reduce the wear of the workpiece on the pallet 20.

[0027] Working principle: The steel support frame 4 is a fixed bracket welded from metal. The steel support frame 4 can provide stable support for steel workpieces. The cantilever seat 2 drives the robotic arm 3 and the laser head to move along the cutting machine slide rail 1 to one side of the steel support frame 4, and the laser head can then cut the steel workpieces. The pipe support platform 5 can provide stable support for pipe workpieces. The cantilever seat 2 drives the robotic arm 3 and the laser head to move along the cutting machine slide rail 1 to one side of the pipe support platform 5, and the laser head can then cut the pipe workpieces.
