Fully automatic CNC laser tube cutting machine

Abstract

This invention relates to the field of laser cutting technology and provides a fully automatic CNC laser tube cutting machine, including a front chuck mechanism. The front chuck mechanism includes a chuck body and an adaptive jaw assembly. The adaptive jaw assembly includes a front support jaw and a jaw adjustment support base. The front support jaw includes a front support jaw body, which is composed of multiple unit front support jaws. The multiple unit front support jaws are elastically interlocked. During the process of the front support jaws abutting against the tube, the multiple unit front support jaws elastically contract locally or in multiple locations according to the different shapes of the tube surface. After the front support jaws are attached to the tube, they are magnetically attracted and fixed by energizing. This eliminates the need for direct and forceful compression, avoiding damage to the tube when its strength is low, and preventing loosening due to incorrect force points when facing different tube surface shapes.

Description

Technical Field

[0001] This invention relates to the field of laser cutting technology, and more specifically, to a fully automatic CNC laser tube cutting machine. Background Technology

[0002] Laser cutting utilizes a focused, high-power-density laser beam to irradiate the workpiece, causing the irradiated material to rapidly melt, vaporize, or reach its ignition point. Simultaneously, a high-speed airflow coaxial with the laser beam blows away the molten material, thus cutting the workpiece. It is one of the thermal cutting methods for cutting workpieces. Specifically, when the focused laser beam shines on the workpiece, the irradiated area heats up rapidly, causing the material to melt or vaporize. Once the laser beam penetrates the workpiece, the cutting process begins; the laser beam moves along the contour line, melting the material along the way. Typically, a jet of air is used to blow the molten material away from the cut, leaving a narrow slit between the cut section and the workpiece, almost as wide as the focused laser beam.

[0003] With the progress of the times and the development of technology, laser cutting has gradually come into the view of toolmakers. Compared with traditional processes, laser cutting technology is more efficient, faster, safer and more practical.

[0004] Meanwhile, existing laser tube cutting machines typically require a chuck to position the tube during the cutting process. However, most existing chucks use rollers for positioning, which has poor adaptability when dealing with different shapes on the surface of different tubes. They generally rely on direct, forceful compression, which can easily loosen the tube and damage it if the tube is not strong enough. For example, the "claw assembly" described in Chinese Patent No. CN113199162B, which uses a "roller" for positioning, also suffers from poor adaptability and relies on direct, forceful compression, which can easily loosen the tube and damage it if the tube is not strong enough.

[0005] Therefore, in response to the problem that "existing chucks are mostly positioned by rollers, but their adaptability to different shapes of different pipe surfaces is poor. They are generally squeezed directly with great force, which is easy to loosen on the one hand, and easy to damage the pipe when the pipe strength is not high", a fully automatic CNC laser pipe cutting machine is proposed. Summary of the Invention

[0006] Technical problem: The purpose of this invention is to solve the shortcomings of the existing technology: existing chucks are mostly positioned by rollers, but their adaptability to different shapes of different pipe surfaces is poor. Generally, they are directly squeezed with great force, which is easy to loosen on the one hand, and easy to damage the pipe when the pipe strength is not high on the other hand. Therefore, the fully automatic CNC laser pipe cutting machine is proposed.

[0007] The specific technical solution is as follows: a fully automatic CNC laser tube cutting machine, including a laser tube cutting machine body, the laser tube cutting machine body including a laser tube cutting machine housing, a front chuck mechanism installed inside the laser tube cutting machine housing, the front chuck mechanism being used to position the tube; the front chuck mechanism including a chuck body and adaptive jaw components, multiple adaptive jaw components being arranged in a circular array on the chuck body; the adaptive jaw components including a front support jaw and a jaw adjustment support seat, the front support jaw being assembled on the jaw adjustment support seat, the jaw adjustment support seat being assembled on the chuck body; the front support jaw including a front support jaw body, the front support jaw body being composed of multiple unit front support jaws, the multiple unit front support jaws being arranged in multiple rows and columns in a parallel array; the multiple unit front support jaws are all elastically interlocked, the multiple unit front support jaws being attracted and limited after being energized and magnetically attracted; during the process of the front support jaws abutting against the tube, the multiple unit front support jaws, according to the different tube surface... For different shapes, multiple elastic contractions are performed in one or more locations to complete the front support claws' fit onto the pipe fitting. After the front support claws are energized and become magnetic, they are used for adsorption and positioning. The pipe fitting is placed on the main body of the laser pipe cutting machine and pushed into the machine housing. The front chuck mechanism positions the pipe fitting. During this process, multiple adaptive claws are pushed towards the pipe fitting from all sides. Multiple front support claws are used to perform elastic contractions in one or more locations according to the different shapes of the pipe fitting surface. After the front support claws are fitted onto the pipe fitting, they are energized and become magnetic, then used for adsorption and positioning. This allows the front support claws to create recesses that match the different shapes of the pipe fitting surface, ensuring a proper fit. This avoids direct, forceful compression, preventing damage to the pipe fitting when its strength is low, and also prevents loosening due to incorrect force points when dealing with different pipe fitting surface shapes.

[0008] In the technical solution of the present invention, the main body of the laser tube cutting machine also includes a material guide base, one end of which is installed on the housing of the laser tube cutting machine, and multiple support feet are added to the bottom of the material guide base; a rear chuck mechanism is slidably installed on the material guide base; a cutting cavity is opened inside the housing of the laser tube cutting machine, and a front chuck mechanism is installed inside the cutting cavity; an operation panel is installed on the surface of the housing of the laser tube cutting machine.

[0009] In the technical solution of the present invention, the chuck body includes a positioning drive body and a rotating body, and a plurality of adaptive jaw components are arranged in a ring array on the rotating body; the positioning drive body is used to drive the rotating body to rotate and drive the plurality of adaptive jaw components to rotate.

[0010] Furthermore, the rotating body is a rotating disk, and an installation cavity is provided inside the rotating disk, with multiple adaptive claw components arranged in a ring array inside the installation cavity.

[0011] The optimized positioning drive includes a drive ring, which is rotatably mounted on a positioning ring. The positioning ring is fixed on a support base, which is fixed on a mounting plate. Multiple mounting bolts are threaded through the mounting plate and are used to install the mounting plate inside the housing of the laser tube cutting machine. The drive ring is fixed on a rotating disk, and a rack ring is sleeved on the outside of the drive ring. The rack ring meshes with a gear, and the gear is fixed on the output shaft of the drive motor.

[0012] Start the drive motor, which drives the gears, which transmit power to the rack ring. This causes the rack ring to rotate, thus rotating the positioning drive body and multiple adaptive chuck components.

[0013] In the technical solution of the present invention, the front support claw further includes a storage seat, which is installed on the claw adjustment support seat, and multiple unit front support claws are elastically inserted into the storage seat; a cable terminal block is installed on the storage seat, and the cable terminal block is connected to the multiple unit front support claws one by one through multiple conductive wires; the cable terminal block is externally connected to the power supply through the installed cable.

[0014] Furthermore, the unit's front support claw includes a support column, with an elastic telescopic rod installed at one end of the support column. The end of the elastic telescopic rod away from the support column is fixed to the storage base. A hinged ball 2 is movably mounted at the end of the support column away from the elastic telescopic rod. Installation grooves are respectively opened on the four walls of the support column, and magnetic adsorption plates are installed inside the installation grooves. The support column is a quadrangular prism and is made of iron. Electromagnetic coils are laid inside the ball hinge cavities of the magnetic adsorption plate and the support column for movably mounting the hinged ball 2.

[0015] The optimized elastic telescopic rod includes a telescopic rod and a spring. The telescopic rod is fixed inside an installation cavity opened on the support column; the spring is sleeved on the telescopic rod.

[0016] During the process of the front support claws abutting against the pipe fitting, multiple front support claws are used in one or more places according to the different shapes of the pipe fitting surface. They are elastically retracted into the storage seat using elastic telescopic rods. After the front support claws are attached to the pipe fitting, the magnetic adsorption plate and the ball joint cavity are energized so that the magnetic adsorption plate and the ball joint cavity become magnetic and are adsorbed and limited.

[0017] In the technical solution of the present invention, the claw adjustment support includes a motor and a lifting rod, and a turntable is fixed on the output shaft of the motor, and the turntable is fixed on the front support claw;

[0018] A reinforcing support frame is installed between the motor and the lifting rod. A base plate is fixed to the end of the lifting rod away from the reinforcing support frame, and multiple mounting holes are opened on the base plate.

[0019] The motor drives the front support claw to rotate at an angle so that the front support claw can fit onto the different shapes of different pipe fittings at the most suitable point of force.

[0020] Furthermore, the reinforcing support frame includes a fixed plate, which is fixed between the motor and the lifting rod; a horizontal plate is fixed on each side of the fixed plate, and a support column is vertically fixed on the horizontal plate, with a hinged ball movably disposed at the end of the support column.

[0021] Compared with existing technologies, the fully automatic CNC laser tube cutting machine of this invention can achieve the following:

[0022] 1. Place the tube on the main body of the laser tube cutting machine and push it into the machine housing. Use the front chuck mechanism to position the tube. During this process, multiple adaptive claws push the tube from all sides. Multiple unit front support claws are used to perform elastic contraction in one or more places according to the different shapes of the tube surface. After the front support claws are attached to the tube, the unit front support claws are energized and become magnetic to attract and limit the tube. This allows the front support claws to make concave shapes that match the different shapes of the tube surface and adapt to fit. This avoids the need for direct and strong squeezing, which can easily damage the tube when its strength is not high. It also prevents the tube from loosening due to incorrect force points when facing different shapes of different tube surfaces.

[0023] 2. The motor drives the front support claw to rotate at an angle so that the front support claw can fit onto the different shapes of different pipe fittings at the most suitable point of force. Attached Figure Description

[0047] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to specific embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the invention. All other embodiments obtained by those skilled in the art based on the embodiments of this invention without inventive effort are within the scope of protection of this invention.

[0048] In embodiments of the present invention, such as Figure 1-3 As shown in Figures 5, 6, and 8: A fully automatic CNC laser tube cutting machine includes a laser tube cutting machine body, which includes a laser tube cutting machine housing 100. A front chuck mechanism 300 is installed inside the laser tube cutting machine housing 100. The front chuck mechanism 300 is used to position the tube 700.

[0049] Therefore, summarizing the above, it can be concluded that: the pipe fitting 700 is placed on the main body of the laser pipe cutting machine and pushed into the machine housing 100 (for details, please refer to...). Figure 2 (Demonstration diagram of fully automatic CNC laser tube cutting machine) The front chuck mechanism 300 is used to position the tube 700, and finally the laser cutting head is used for fully automatic CNC laser cutting.

[0050] The description of the "laser cutting head" is as follows: The laser cutting head is mounted on a robotic arm. Both the robotic arm and the laser cutting head are existing technologies. Their detailed structures can be found in existing literature and journals. They can also be purchased directly from the market or assembled from parts purchased from the market. They are not protected by this invention and will not be described in detail here, nor are they shown in the accompanying drawings.

[0051] The front chuck mechanism 300 includes a chuck body 310 and an adaptive jaw 320. Multiple adaptive jaws 320 are provided and distributed in a circular array on the chuck body 310.

[0052] The adaptive jaw assembly 320 includes a front support jaw 321 and a jaw adjustment support 322. The front support jaw 321 is mounted on the jaw adjustment support 322, and the jaw adjustment support 322 is mounted on the chuck body 310.

[0053] Therefore, summarizing the above, it can be concluded that: when the tube 700 is placed on the main body of the laser tube cutting machine and pushed into the machine housing 100, the front chuck mechanism 300 positions the tube 700. During this process, multiple adaptive jaws 320 push the tube 700 from all sides, and the front support jaws 321 create recesses (e.g., ) that match different shapes on the surface of the tube 700 (here, "shape" specifically refers to the surface shape 800 of the tube, and will be referred to as "shape" hereinafter) on the same surface. Figure 12 The demonstration diagram of the arc-shaped concave mentioned in the text and Figure 13 (The diagram of the inclined concave surface mentioned in the text) and adapts to the fit, so that there is no need to directly squeeze with great force, avoiding the situation that the pipe is easily damaged when the pipe strength is not high, and there is no problem of the force point being incorrect and easy to loosen when facing different shapes of different pipe surfaces. Finally, a laser cutting head is used for fully automatic CNC laser cutting.

[0054] The front support claw 321 includes a front support claw body 3211, which is composed of multiple unit front support claws 3212. The multiple unit front support claws 3212 are arranged in multiple rows and columns in a parallel array. The multiple unit front support claws 3212 are all elastically interlocked. The multiple unit front support claws 3212 are attracted and limited after being energized and made magnetic.

[0055] During the process of the front support claws 321 abutting against the pipe fitting 700, multiple unit front support claws 3212, according to the different shapes of the surface of different pipe fittings 700, perform elastic contraction in one local area or multiple local areas, to complete the front support claws 321 fitting onto the pipe fitting 700 (see details for reference). Figure 11The adaptive claw component 320 uses the front support claw body 321 to adapt to different shapes of different pipe fitting surfaces. (AF is a demonstration of the adaptive deformation of the front support claw body 321 to adapt to different shapes of different pipe fitting surfaces.) The unit front support claw 3212 is attracted and limited after being energized and becoming magnetic.

[0056] Therefore, summarizing the above, it can be concluded that: when the tube 700 is placed on the main body of the laser tube cutting machine and pushed into the machine housing 100, the front chuck mechanism 300 is used to position the tube 700. During this process, multiple adaptive jaws 320 are pushed towards the tube 700 from all sides, and multiple unit front support jaws 3212 are used to elastically contract in one or more places according to the different shapes of the surface of different tubes 700. After the front support jaws 321 are attached to the tube 700, the unit front support jaws 3212 are energized and become magnetic to attract and limit their position. This ensures that the front support jaws 321 make concave depressions that match the different shapes of the surface of the tube 700 and adapt to fit, thus avoiding direct and forceful compression. This avoids damage to the tube when its strength is not high, and also prevents loosening due to incorrect force points when facing different shapes of the surface of different tubes 700.

[0057] In embodiments of the present invention, such as Figure 1 and Figure 2 As shown: The main body of the laser tube cutting machine also includes a guide base 400, one end of which is mounted on the machine housing 100 of the laser tube cutting machine, and multiple support feet are added to the bottom of the guide base 400; a rear chuck mechanism 500 is slidably mounted on the guide base 400.

[0058] The laser tube cutting machine housing 100 has a cutting cavity 600 inside, and a front chuck mechanism 300 is installed inside the cutting cavity 600; an operation panel 200 is installed on the surface of the laser tube cutting machine housing 100.

[0059] The description of the "rear chuck mechanism 500" is as follows: The rear chuck mechanism 500 is prior art, and its detailed structure can be found in existing literature and journals. It can also be purchased directly on the market, or its components can be purchased on the market and assembled, etc. It is not protected by this invention, and will not be described in detail here.

[0060] In embodiments of the present invention, such as Figure 3 and Figure 4 As shown: The chuck body 310 includes a positioning drive body and a rotating body, and multiple adaptive jaw pieces 320 are arranged in a ring array on the rotating body;

[0061] The positioning drive is used to drive the rotating body to rotate and drive multiple adaptive chuck parts 320 to rotate.

[0062] In embodiments of the present invention, such as Figure 3 and Figure 4 As shown: The rotating body is a rotating disk 313, and the rotating disk 313 has an installation cavity inside, and multiple adaptive claw parts 320 are distributed in a ring array inside the installation cavity.

[0063] like Figure 4 As shown: The positioning drive body includes a drive ring 312, which is rotatably mounted on a positioning ring 311. The positioning ring 311 is fixed on a support base 314, and the support base 314 is fixed on a mounting plate 315. Multiple mounting bolts 316 are threaded through the mounting plate 315. The mounting bolts 316 are used to install the mounting plate 315 inside the housing 100 of the laser tube cutting machine.

[0064] The drive ring 312 is fixed on the rotating disk 313. A rack ring is sleeved on the outside of the drive ring 312. The rack ring meshes with a gear. The gear is fixed on the output shaft of the drive motor.

[0065] Therefore, summarizing the above, we can conclude that: starting the drive motor drives the gear, which in turn transmits power to the rack ring, thereby causing the rack ring to rotate and the drive ring 312 to rotate, thus completing the rotation of the positioning drive body and driving multiple adaptive chuck parts 320 to rotate.

[0066] In embodiments of the present invention, such as Figure 6 As shown: The front support claw 321 also includes a storage seat 3213, which is mounted on the claw adjustment support seat 322, and multiple unit front support claws 3212 are elastically inserted into the storage seat 3213.

[0067] The storage base 3213 is equipped with a cable terminal block 3214, which is connected to multiple front support claws 3212 of the unit through multiple conductive wires; the cable terminal block 3214 is connected to the power supply through the installed cable 3215.

[0068] It should be noted that the conductive wire has sufficient length to be flexibly inserted with the unit's front support claw 3212. The power supply is existing technology, and its detailed structure can be found in existing literature and journals. It can also be purchased directly on the market, or components can be purchased on the market to assemble it, etc. It is not protected by this invention, so it will not be described in detail here, nor is it shown in the accompanying drawings.

[0069] In embodiments of the present invention, such as Figure 8-10 As shown: The unit front support claw 3212 includes a support column 32122, one end of which is equipped with an elastic telescopic rod, and the end of the elastic telescopic rod away from the support column 32122 is fixed to the storage base 3213.

[0070] The support column 32122 has a movable hinge ball 32121 at the end away from the elastic telescopic rod; the support column 32122 has mounting grooves 32124 on its four sides, and a magnetic adsorption plate 32123 is installed inside the mounting grooves 32124.

[0071] The support column 32122 is a quadrangular prism and is made of iron; the magnetic adsorption plate 32123 and the support column 32122 are used to movably install the hinge ball 32121. The ball hinge cavity is filled with electromagnetic coils (it should be noted that the electromagnetic coils are laid inside the surface and do not exist on the surface).

[0072] It should be noted that the support column 32122 can be in the shape of a triangular prism, a pentagonal prism, or a hexagonal prism, etc., in addition to being a quadrangular prism. These are all existing technologies, and there is no limitation on its specific structure, as long as multiple front support claws 3212 are arranged in multiple rows and columns in a parallel array. At the same time, its shape has been described in relevant journal literature and is not what this invention is intended to protect, so it will not be described in detail here.

[0073] In embodiments of the present invention, such as Figure 8-10 As shown: The elastic telescopic rod includes a telescopic rod 32125 and a spring 32126. The telescopic rod 32125 is fixed inside the mounting cavity 32127 opened on the support column 32122; the spring 32126 is sleeved on the telescopic rod 32125.

[0074] Therefore, summarizing the above, it can be concluded that during the process of the front support claw 321 abutting against the pipe fitting 700, multiple unit front support claws 3212, according to the different shapes of the surface of different pipe fittings 700, are partially multiple in one place or multiple partially multiple in multiple places, and are elastically retracted into the storage seat 3213 using elastic telescopic rods. After the front support claws 321 are attached to the pipe fitting 700, the magnetic adsorption plate 32123 and the ball joint cavity are energized, so that the magnetic adsorption plate 32123 and the ball joint cavity have magnetism and are adsorbed and limited.

[0075] It should be noted that the magnetic adsorption plate 32123 and the ball joint cavity can be energized independently.

[0076] In embodiments of the present invention, such as Figure 5 and Figure 7 As shown: The claw adjustment support 322 includes a motor 3222 and a lifting rod 3224. The motor 3222 has a turntable 3221 fixed on its output shaft. The turntable 3221 is fixed on the front support claw 321.

[0077] A reinforcing support frame 3223 is installed between the motor 3222 and the lifting rod 3224. A base plate 3225 is fixed to the end of the lifting rod 3224 away from the reinforcing support frame 3223. Multiple mounting holes 3226 are provided on the base plate 3225.

[0078] Therefore, summarizing the above, we can conclude that: when the motor 3222 is started, the motor 3222 drives the front support claw 321 to rotate at an angle so that the front support claw 321 can fit onto the different shapes on the surface of different pipe fittings 700 with the most suitable force point.

[0079] In embodiments of the present invention, such as Figure 5 and Figure 7 As shown: The reinforcing support frame 3223 includes a fixed plate 32234, which is fixed between the motor 3222 and the lifting rod 3224; a horizontal plate 32233 is fixed on each side of the fixed plate 32234, and a support column 32232 is vertically fixed on the horizontal plate 32233. A hinge ball 32231 is movably arranged at the end of the support column 32232.

[0080] It should be noted that the lifting rod 3224 can be a hydraulic telescopic rod, a pneumatic telescopic rod, or an electric telescopic rod, etc., all of which are existing technologies. There is no limitation on its specific structure, as long as it can drive the front support claw 321 to adjust its position. At the same time, its shape has been described in relevant journal literature and is not what this invention is intended to protect, so it will not be described in detail here.

[0081] Existing chucks mostly use rollers for positioning, but their adaptability to different tube surface shapes is poor. They generally rely on direct, high-pressure compression, which can easily lead to loosening and damage to tubes with low strength. This invention, a fully automatic CNC laser tube cutting machine, can achieve the following:

[0082] The tube 700 is placed on the main body of the laser tube cutting machine and pushed into the machine housing 100. The front chuck mechanism 300 positions the tube 700. During this process, multiple adaptive jaws 320 push the tube 700 from all sides, and multiple unit front support jaws 3212 elastically contract according to the different shapes of the tube 700 surface, either in one area or in multiple areas. After the front support jaws 321 are attached to the tube 700, the unit front support jaws 3212 are energized to become magnetic. After adsorption and positioning, the front support claw 321 is used to create recesses that match the different shapes of the pipe fitting 700 surface, and adapts to fit. This eliminates the need for direct and forceful compression, avoiding damage to the pipe fitting when its strength is low, and preventing loosening due to incorrect force points when facing different shapes of the pipe fitting 700 surface. The motor 3222 drives the front support claw 321 to rotate at an angle so that the front support claw 321 can fit the different shapes of the different pipe fitting 700 surface with the most suitable force point.
