It includes a processing platform, the top of which is equipped with a pipe fitting limiting mechanism. This invention controls the independent rotation of an outer rotating ring and an inner rotating ring. With several sets of connecting rods and mounting rods alternately connected, these sets of connecting rods and mounting rods can enter the pipe fitting from both ends.

Description

Technical Field

[0001] This invention belongs to the field of electrical connection pipe processing technology, and specifically relates to a laser cutting device for electrical connection metal pipes. Background Technology

[0002] Electrical connection pipes are used to prevent cables and wires from being damaged by mechanical factors (such as collisions and friction) and from environmental corrosion (such as moisture, acids and alkalis). The materials of the connection pipes used vary depending on the usage conditions. For example, metal connection pipes are mostly used for shielding external electromagnetic fields, resisting pressure and impact, and need to be cut according to the usage requirements.

[0003] A search revealed that Chinese Patent Publication No. CN118951393B, published on April 8, 2025, discloses a laser cutting device for bending metal tubes. The device includes a frame and a mounting base on the frame. A fixed plate is rotatably mounted on the top of the mounting base, and a mounting groove is formed on the top of the fixed plate. The bent metal tube is movably mounted in the mounting groove, with both ends protruding from the fixed plate. Two sets of mounting grooves are evenly spaced around the rotation axis of the fixed plate. A laser cutting head is raised and rotated on the frame, always facing the outer peripheral wall of the bent metal tube. The frame is equipped with an adjustment mechanism for driving the laser cutting head to rise and rotate. A preheating assembly for preheating the bent metal tube is also provided on the frame. A deburring assembly for the bent metal tube is also provided on the mounting base. This application facilitates simultaneous laser cutting and deburring, improving processing efficiency and grinding quality.

[0004] However, the device still has the following drawbacks:

[0005] When using metal pipes for electrical connections, it is usually necessary to select metal pipes with different degrees of bending according to the usage environment. However, existing laser cutting devices can only complete the limiting work of metal pipes with fixed bending degrees, which makes it impossible for the metal pipe to remain stable during the cutting process, thus reducing the cutting effect of the laser cutting device.

[0012] Furthermore, the laser generating mechanism includes a mounting base and a laser head; a connecting magnetic column is provided at the bottom center of the mounting base; a connecting magnetic plate is provided at the top of the laser head; the connecting magnetic plate is magnetically connected to the connecting magnetic column; and two sets of sliding grooves are symmetrically opened at the bottom of the mounting base.

[0013] Furthermore, each set of sliding grooves is provided with a set of sliding rods; each set of sliding rods is elastically hinged to a set of rotating rods at the end away from the mounting base; each set of rotating rods is damp-hinged to a set of protective plates at the end away from the corresponding set of sliding rods; the two sets of protective plates are combined to form a ring structure; each set of protective plates is elastically hinged to a set of bottom covers at the bottom; each set of protective plates is movably connected to a set of connecting fan plates at the top; each set of connecting fan plates is magnetically connected to a connecting magnetic plate.

[0014] Furthermore, the pipe support assembly includes a support disc; an installation slot is provided at the center of the support disc; two sets of brake plates are symmetrically and movably inserted through the inner walls on both sides of the installation slot; each set of brake plates is movably inserted into a corresponding set of storage slots.

[0015] Furthermore, several sets of second electric push rods are arranged in a circular array inside the support disk; each set of second electric push rods is connected to a set of abutting blocks at the end away from the support disk; the side wall of each set of abutting blocks away from the support disk is set as a curved surface and has a set of telescopic grooves.

[0016] Furthermore, each set of telescopic grooves has a set of universal balls that move through it; each set of universal balls has a set of return springs at one end near the support disc; and the other end of each set of return springs is connected to the inner wall of the telescopic groove on the side near the support disc.

[0017] Furthermore, the slag cleaning mechanism includes a mounting ring; the bottom of the mounting ring is provided with several sets of third electric push rods arranged in a circular array; the bottom of each set of third electric push rods is installed on the top of the pipe fitting limiting mechanism; a rotating mounting ring is provided on the inner wall of the mounting ring; two sets of fourth electric push rods are symmetrically arranged on the inner wall of the rotating mounting ring; a cleaning ring is connected to the output end of the two sets of fourth electric push rods.

[0019] The beneficial effects of this invention are:

[0020] 1. By controlling the independent rotation of the outer and inner rings, and with several sets of connecting rods and mounting rods alternately connected, the corresponding sets of connecting rods and mounting rods can enter the pipe from both ends. Subsequently, four sets of pipe support components reach the two ends and the cutting port of the pipe and abut against the inner wall of the pipe to complete the fixing of the pipe. This not only enables the fixing of pipes with different degrees of curvature, but also provides support for the cutting ports on both sides of the cutting area, preventing the high temperature of the laser from softening and collapsing the cutting ports of the pipe, thereby improving the cutting effect of the laser cutting device.

[0021] 2. By controlling several sets of second electric push rods to drive several sets of contact blocks to extend outward, several sets of universal balls will contact the inner wall of the pipe fitting for guidance. When the four sets of pipe fitting support components reach the corresponding positions, control several sets of second electric push rods to continue to extend, causing several sets of universal balls to retract into the corresponding telescopic grooves, and several sets of contact blocks will contact the inner wall of the pipe fitting to form a pipe fitting positioning effect. In addition, several sets of support discs are connected and fixed by two sets of brake plates and mounting rods, so that the positioning mechanism of the laser cutting device is not only easy to disassemble and assemble, but also can realize the positioning work of electrical connection metal pipes of different lengths.

[0022] 3. By controlling the rotating mounting ring, the two sets of cleaning plates can be adjusted to the corresponding angle. By controlling the two sets of fourth electric push rods, the two sets of cleaning plates can be adjusted to the horizontal position. This ensures that regardless of the fixing angle of the pipe fitting, the cleaning grooves at the bottom of the two sets of cleaning plates can reach both sides of the pipe fitting cutting area in conjunction with the internal fixing of the pipe fitting. As a result, when the pipe fitting is laser cut, the several sets of cleaning holes on the inner wall of the cleaning grooves on both sides can more accurately clean the slag in the pipe fitting cutting area, thus improving the slag cleaning effect of the laser cutting mechanism.

[0023] 4. When the laser cutting device is idle, the two sets of sliding rods can continue to move relative to each other by controlling the sliding rods, rotating rods and protective plates. With the corresponding connection method of the sliding rods, rotating rods and protective plates, the two sets of protective plates can be lowered against the outer wall of the laser head until the two sets of bottom covers are combined to complete the sealing of the laser head. At the same time, the connecting fan plate that moves through the top of the two sets of protective plates can be adsorbed onto the bottom of the connecting magnetic plate, so that the laser head can be fully wrapped. This not only improves the maintenance efficiency of the laser cutting device, but also extends the service life of the laser cutting device.

Detailed Implementation

[0036] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0037] This invention provides a laser cutting device for metal tubes used in electrical connections, including a processing platform 1. For example,... Figure 1As shown, two sets of support columns 2 are symmetrically arranged at the top two sides of the processing platform 1; a first electric slide 3 is provided at the top of the two sets of support columns 2; a second electric slide 4 is driven to the bottom of the first electric slide 3; a first electric push rod 5 is driven to the bottom of the second electric slide 4; the support columns 2, the first electric slide 3, the second electric slide 4 and the first electric push rod 5 are combined to form a spatial movement mechanism; a laser generating mechanism 6 is driven to the output end of the first electric push rod 5; a pipe fitting limiting mechanism 7 is provided at the top of the processing platform 1; a slag cleaning mechanism 8 is provided at the top of the pipe fitting limiting mechanism 7.

[0038] When performing laser cutting of electrical connection metal tubes, the electrical connection metal is first fixed on the top of the tube limiting mechanism 7. At the same time, the vertical setting of the first electric slide 3 and the second electric slide 4, together with the first electric push rod 5, can drive the laser generating mechanism 6 to move in three-dimensional space. When controlling the laser generating mechanism 6 to cut the electrical connection metal tube, the slag cleaning mechanism 8 can be controlled to precisely clean the slag in the cutting area.

[0039] For example, such as Figure 2 and Figure 3 As shown, the laser generating mechanism 6 includes a mounting base 601 and a laser head 602; a connecting magnetic column 603 is provided at the center of the bottom of the mounting base 601; a connecting magnetic plate 604 is provided at the top of the laser head 602; the connecting magnetic plate 604 is magnetically connected to the connecting magnetic column 603; two sets of sliding grooves 605 are symmetrically opened at the bottom of the mounting base 601; a set of sliding rods 606 is provided in each set of sliding grooves 605; a set of rotating rods 607 is elastically hinged to the end of each set of sliding rods 606 away from the mounting base 601.

[0040] Specifically, each set of rotating rods 607 has a set of protective plates 608 damped and hinged at one end away from the corresponding set of sliding rods 606; the two sets of protective plates 608 are combined to form a ring structure; the bottom of each set of protective plates 608 is elastically hinged to a set of bottom covers; the top of each set of protective plates 608 has a set of connecting fan plates 610 that can be movably passed through; each set of connecting fan plates 610 is magnetically connected to a connecting magnetic plate 604; the mounting base 601 is provided with a transmission cavity 611;

[0041] Specifically, the transmission cavity 611 is provided with two sets of lead screws 612; one end of the two sets of lead screws 612 is fixedly connected, and the other end is rotatably connected to the inner walls on both sides of the transmission cavity 611; the thread directions of the two sets of lead screws 612 are opposite, and their central axes are on the same straight line; two sets of sliders 613 are slidably connected to the bottom inner wall of the transmission cavity 611; each set of sliders 613 is threadedly connected to a corresponding set of lead screws 612; each set of sliders 613 is drivenly connected to a corresponding set of sliding rods 606.

[0042] During the installation of the laser head 602, the laser head 602 is first attached to the bottom of the connecting magnetic post 603 at the bottom of the mounting base 601 by the connecting magnetic plate 604 at the top of the laser head 602. The connecting magnetic post 603 extends into the connecting magnetic plate 604. Then, the two sets of lead screws 612 are rotated. With the threaded connection between the two sets of lead screws 612 and the two sets of sliders 613, the two sets of sliders 613 drive the two sets of protective plates 608 to wrap around the outer wall of the laser head 602 through the two sets of sliding rods 606 and rotating rods 607. At the same time, the two sets of protective plates 608 abut against the bottom of the connecting magnetic plate 604.

[0043] Specifically, when the laser cutting device is idle, the two sets of sliding rods 606 can continue to move relative to each other by controlling the sliding rods 606, rotating rods 607 and protective plates 608 to descend and adhere to the outer wall of the laser head 602 until the two bottom covers 609 merge to complete the sealing of the laser head 602. At the same time, the connecting fan plate 610 that moves through the top of the two sets of protective plates 608 can be adsorbed onto the bottom of the connecting magnetic plate 604, so that the laser head 602 can be completely wrapped. This not only improves the maintenance efficiency of the laser cutting device, but also extends the service life of the laser cutting device.

[0044] For example, such as Figure 4 and Figure 5 The pipe fitting limiting mechanism 7 includes a limiting base 701; a rotating outer ring 702 is provided on the top of the limiting base 701; a rotating inner ring 703 is provided on the inner wall of the rotating outer ring 702; a set of mounting plates 704 are respectively provided on the top of the rotating outer ring 702 and the rotating inner ring 703; several sets of connecting rods 705 and mounting rods 706 are provided on one side wall of each set of mounting plates 704 near the central axis of the limiting base 701; the several sets of connecting rods 705 and mounting rods 706 are alternately connected; two sets of receiving grooves 708 are symmetrically opened on both sides of each set of mounting rods 706; each set of connecting rods 705 moves through the corresponding set of receiving grooves 708; two sets of pipe fitting support assemblies 707 are sleeved on the outer wall of the several sets of mounting rods 706 on the same side.

[0045] When performing laser cutting of electrical connection metal tubes, the electrical connection metal tube is placed at the top center of the limiting base 701. Then, the outer rotating ring 702 and the inner rotating ring 703 are controlled to rotate independently, so that the corresponding sets of connecting rods 705 and mounting rods 706 are aligned with the two ends of the electrical connection metal tube. Subsequently, the connecting rods 705 and mounting rods 706 are alternately connected and driven, so that the corresponding sets of connecting rods 705 and mounting rods 706 enter from both ends of the tube. The corresponding two sets of tube support components 707 reach both sides of the cutting area, and the other two sets of tube support components 707 are located at the two ends of the tube. Then, the four sets of tube support components 707 are controlled to abut against the inner wall of the tube to complete the tube fixing work. This not only enables the fixing of tubes with different degrees of curvature, but also provides support for the cutting ends on both sides of the cutting area, preventing the tube cutting ends from softening and collapsing due to the high temperature of the laser, thereby improving the cutting effect of the laser cutting device.

[0046] For example, such as Figure 6 and Figure 7 As shown, the pipe support assembly 707 includes a support disc 7071; a mounting slot 7072 is provided at the center of the support disc 7071; two sets of brake plates 7073 are symmetrically and movably inserted through the inner walls on both sides of the mounting slot 7072; each set of brake plates 7073 is movably inserted into a corresponding set of receiving slots 708; several sets of second electric push rods 7074 are arranged in a circular array inside the support disc 7071; each set of second electric push rods 7074 is located away from the support disc 7071. Each end is connected to a set of abutment blocks 7075; the side wall of each set of abutment blocks 7075 away from the support disk 7071 is set as a curved surface and has a set of telescopic grooves 7076; a set of universal balls 7077 are movably inserted in each set of telescopic grooves 7076; a set of return springs 7078 is provided at the end of each set of universal balls 7077 near the support disk 7071; the other end of each set of return springs 7078 is connected to the inner wall of the telescopic groove 7076 near the support disk 7071.

[0047] During laser cutting of electrical connection metal pipes, several sets of connecting rods 705 and mounting rods 706 enter from both ends of the pipe. Then, several sets of second electric push rods 7074 are controlled to drive several sets of abutment blocks 7075 to extend outward, so that several sets of universal balls 7077 abut against the inner wall of the pipe for guidance. When the four sets of pipe support components 707 are respectively located at the two ends of the pipe and the cutting end, several sets of second electric push rods 7074 are controlled to continue to extend, so that several sets of universal balls 7077 retract into the corresponding telescopic grooves 7076, and several sets of abutment blocks 7075 abut against the inner wall of the pipe to form a pipe positioning effect. In addition, several sets of support discs 7071 are respectively connected and fixed to the mounting rods 706 by two sets of brake plates 7073. This makes the positioning mechanism of the laser cutting device not only easy to disassemble and assemble, but also able to achieve positioning of electrical connection metal pipes of different lengths.

[0048] For example, such as Figure 8 and Figure 9 As shown, the slag cleaning mechanism 8 includes a mounting ring 801; several sets of third electric push rods 802 are arranged in a circular array at the bottom of the mounting ring 801; the bottom of each set of third electric push rods 802 is mounted on the top of the pipe fitting limiting mechanism 7; a rotating mounting ring 803 is provided on the inner wall of the mounting ring 801; two sets of fourth electric push rods 804 are symmetrically arranged on the inner wall of the rotating mounting ring 803; a cleaning ring 805 is connected to the output end of the two sets of fourth electric push rods 804; two sets of cleaning plates 806 are symmetrically arranged at the bottom of the cleaning ring 805; the cross-section of each set of cleaning plates 806 is Z-shaped, and a set of cleaning grooves 808 is opened at the end away from the cleaning ring 805; several sets of cleaning holes are equally spaced on the inner wall of each set of cleaning grooves 808; two sets of dust suction structures 807 are provided on the top of the mounting ring 801; each set of dust suction structures 807 is connected to a corresponding set of cleaning plates 806 through the cleaning ring 805.

[0049] During laser cutting of metal pipes for electrical connections, the rotating mounting ring 803 can be controlled to adjust the two sets of cleaning plates 806 to the corresponding angles. The two sets of fourth electric push rods 804 can be controlled to adjust the two sets of cleaning plates 806 to the horizontal position. This ensures that regardless of the fixing angle of the pipe, the cleaning grooves 808 at the bottom of the two sets of cleaning plates 806 can reach both sides of the pipe cutting area, thus allowing the cleaning holes on the inner walls of the cleaning grooves 808 on both sides to more accurately clean the slag in the pipe cutting area during laser cutting, improving the slag cleaning effect of the laser cutting mechanism.

[0050] By controlling the outer rotating ring 702 and the inner rotating ring 703 to rotate independently, and with the alternating transmission connection of several sets of connecting rods 705 and mounting rods 706, the corresponding sets of connecting rods 705 and mounting rods 706 can enter the interior of the pipe from both ends of the pipe. Subsequently, four sets of pipe support components 707 reach the two ends of the pipe and the cutting port respectively and abut against the inner wall of the pipe to complete the fixing work of the pipe. This not only enables the fixing of pipes with different degrees of curvature, but also provides support for the cutting ports on both sides of the cutting area, preventing the cutting ports of the pipe from softening and collapsing due to the high temperature of the laser, thereby improving the cutting effect of the laser cutting device.

[0051] By controlling several sets of second electric push rods 7074 to drive several sets of abutment blocks 7075 to extend outward, several sets of universal balls 7077 abut against the inner wall of the pipe fitting for guidance. When the four sets of pipe fitting support components 707 reach their respective positions, the control of several sets of second electric push rods 7074 continues to extend, causing several sets of universal balls 7077 to retract into the corresponding telescopic grooves 7076, and several sets of abutment blocks 7075 abut against the inner wall of the pipe fitting to form a pipe fitting positioning effect. In addition, several sets of support discs 7071 are respectively connected and fixed by two sets of brake plates 7073 and mounting rods 706, so that the positioning mechanism of the laser cutting device is not only easy to disassemble and assemble, but also can realize the positioning work of electrical connection metal pipes of different lengths.

[0052] By controlling the rotating mounting ring 803, the two sets of cleaning plates 806 can be adjusted to the corresponding angle. By controlling the two sets of fourth electric push rods 804, the two sets of cleaning plates 806 can be adjusted to the horizontal position. This ensures that regardless of the fixing angle of the pipe fitting, the cleaning grooves 808 at the bottom of the two sets of cleaning plates 806 can reach both sides of the pipe fitting cutting area in conjunction with the internal fixing of the pipe fitting. As a result, during the laser cutting of the pipe fitting, the several sets of cleaning holes on the inner wall of the cleaning grooves 808 on both sides can more accurately clean the slag in the pipe fitting cutting area, thus improving the slag cleaning effect of the laser cutting mechanism.

[0053] When the laser cutting device is idle, the two sets of sliding rods 606 can continue to move relative to each other by controlling the sliding rods 606, rotating rods 607 and protective plates 608. With the corresponding connection of the sliding rods 606, rotating rods 607 and protective plates 608, the two sets of protective plates 608 can be attached to the outer wall of the laser head 602 and descend until the two sets of bottom covers 609 merge to complete the sealing of the laser head 602. At the same time, the connecting fan plate 610 that moves through the top of the two sets of protective plates 608 can be attracted to the bottom of the connecting magnetic plate 604, so that the laser head 602 can be completely wrapped. This not only improves the maintenance efficiency of the laser cutting device, but also extends the service life of the laser cutting device.
