[0002] The laser-guided sawing device is a device that uses laser technology for precise guidance and cutting. Its product structure mainly includes a laser generator, an optical system, a control cabinet, and a mechanical system. The material is cut by a high-energy laser beam generated by the laser generator. The working principle of the device is to utilize the high-temperature characteristics of the laser beam and adjust and position the laser beam through the optical lens group and beam guiding components of the optical system to melt or vaporize the surface of the material to form a cutting groove, thereby achieving precise cutting of the material.

[0003] In the prior art, when laser cutting a metal pipe, the metal pipe needs to be fixed on an operating table, and then the surface of the metal pipe is laser sawed by a laser beam generated by a laser generator. However, in actual operation, there is a certain inconvenience in fixing the metal pipe on the operating table for laser sawing. In addition, due to the thickness of the metal pipe, when the fixed metal pipe is laser sawed, the cut surface of the metal pipe is prone to unevenness. In addition, if the metal pipe is completely cut off, the time consumption of laser sawing will change due to the thickness of the metal pipe, thereby affecting the accuracy of laser sawing of the metal pipe.

[0042] Embodiment 1:

[0043] See also Figure 1-10The present invention provides a laser-guided sawing device, comprising an operating table 1, a laser sawing device 2 is installed on the top surface of one end of the operating table 1, and a movable panel 3 is slidably installed on the bottom top surface of the operating table 1, a rotating ring 4 is rotatably connected at the center of the outer side of the movable panel 3, and a rotary cutting mechanism 5 for the rotating ring 4 to rotate is arranged on the outer surface of the movable panel 3;

[0044] It should be noted that the laser sawing device 2 mainly includes a laser generator and an optical system. Through the optical lens group and the beam guiding mechanism in the optical system, the laser generator generates a high-temperature laser beam to perform laser-guided sawing processing on the material. The operating table 1 is also provided with a laser controller for controlling the output power, frequency, pulse width and other parameters of the laser to achieve precise control of the cutting process. This is a conventional setting in the art, so it will not be described in detail here.

[0045] In addition, the laser saw 2 is provided with a lifting adjustment mechanism on the operating table 1, which mainly includes a rotating wheel, a threaded screw, a lifting plate and a guide rod. The specific operation is: the threaded screw is driven by the rotating wheel to rotate the thread, and the lifting plate is guided up and down by the guide rod, so that the laser saw 2 installed on the lifting plate is subjected to threaded lifting and lowering processing. In addition, the lifting plate is also provided with a displacement adjustment mechanism for horizontal displacement of the laser saw 2, and its displacement direction is the axial direction of the metal pipe to be laser sawed, which is used to perform displacement adjustment on the laser beam emitting tube in the laser saw 2, so as to achieve fine-tuning of the position of the laser beam emitting tube when laser sawing the metal pipe;

[0046] Positioning rods 6, three positioning rods 6 are provided and are rotatably installed on the outer surface of the rotating ring 4 at equal angles in a circle, and the outer surface of the rotating ring 4 is provided with an extrusion positioning mechanism 7 that cooperates with the three positioning rods 6, and one side of each positioning rod 6 is provided with a clamping rod 8 that slides through the rotating ring 4, and the proximal ends of the three clamping rods 8 are fixed with a mounting frame 9, and the inner wall of each mounting frame 9 is rotatably connected with a plurality of clamping rods 10 distributed at equal angles, and the interior of the rotating ring 4 is provided with a clamping mechanism 11 that cooperates with the extrusion positioning mechanism 7;

[0047] It should be noted that, by setting the extrusion positioning mechanism 7, when the metal tube to be laser sawed is in an uninstalled state, the ends of the three positioning rods 6 away from the rotating ring 4 are all distributed toward the central axis of the rotating ring 4, that is, the ends of the three positioning rods 6 away from the rotating ring 4 are arranged close to each other, and at this time, through the mutual cooperation of the extrusion positioning mechanism 7 and the clamping mechanism 11, the three clamping rods 8 are all distributed inside the rotating ring 4 toward the outside of the rotating ring 4, and at this time, the closed circle surrounded by the clamping rods 10 on each installation frame 9 is set to the maximum diameter, which is larger than the outer surface diameter of the metal tube;

[0048] When installing the metal tube to be laser sawed, one end of the metal tube is inserted from the side of the movable panel 3 close to the laser saw 2, so that the end of the metal tube passes through the center of the multiple clamping rods 10 until the outer surface of the metal tube contacts the surface of the positioning rod 6 and is squeezed. At this time, the extrusion positioning mechanism 7 is driven to move until the three positioning rods 6 form an extrusion clamping treatment on the outer surface of the end of the metal tube. At this time, the clamping mechanism 11 moves synchronously with the extrusion positioning mechanism 7, driving the three clamping rods 8 to move synchronously toward the center of the rotating ring 4, so that the multiple clamping rods 10 and the outer surface of the metal tube form a synchronous compression and positioning installation, thereby completing the dual positioning treatment of the inserted end extrusion positioning of the metal tube and the synchronous compression positioning of the outer surface of the metal tube. The operation is simple, time-saving and labor-saving.

[0049] Further Figure 1 , Figure 2 , Figure 5 and Fig. 9 As shown, it is worth to explain in detail that the peeling mechanism 5 includes a rotating gear ring 51, which is rotatably embedded in the center of the inner wall of the movable panel 3, and three connecting rods 52 with equal angles are fixed between the rotating gear ring 51 and the rotating ring 4;

[0050] A rotating motor 53, which is mounted on the outer surface of the movable panel 3, wherein the output end of the rotating motor 53 is coaxially connected with a rotating gear 54, and the rotating gear 54 is meshedly connected with the rotating gear ring 51;

[0051] It should be noted that after the metal tube is doubly positioned and installed by the extrusion positioning mechanism 7 and the clamping mechanism 11, that is, the metal tube is doubly positioned and installed at the inner center of the rotating ring 4 by three positioning rods 6 and multiple clamping rods 10, the moving panel 3 is moved on the operating table 1, so that the cutting position of the metal tube is aligned with the laser beam emitting tube of the laser sawing device 2. At this time, by starting the laser sawing device 2 and the rotating motor 53, when the laser sawing device 2 generates a high-temperature laser beam to guide the sawing of the metal tube, the rotating motor 53 drives the rotating gear 54 to rotate synchronously, and the meshing transmission between the rotating gear 54 and the rotating gear ring 51 is realized. At this time, the rotating gear ring 51 rotates inside the movable panel 3. At the same time, due to the connecting effect of the connecting rod 52, the rotating ring 4 drives the metal tube that has been double-positioned to rotate, so that the laser beam generated by high temperature is rotated and guided from the outer surface of the metal tube for sawing. Compared with the mobile laser-guided sawing of the laser beam, the flatness of the cutting surface of the metal tube during laser-guided sawing is effectively improved. In addition, due to the mobile laser-guided sawing method, when the laser beam is displaced, the thickness of the laser-cut metal tube is inconsistent. The laser cutting method of the metal tube is used for laser cutting, which can effectively improve the accuracy of the cutting surface of the metal tube.

[0052] Further Figure 3 , Figure 4 , Figure 7 and Fig.10 As shown, it is worth to explain in detail that the extrusion positioning mechanism 7 includes a T-shaped rod 71, three T-shaped rods 71 ​​are provided and fixed to the outer surface of the rotating ring 4 at equal angles, a sliding block 72 is slidably sleeved on the top outer surface of each T-shaped rod 71, and a compression spring 73 is provided on the outer surface of the T-shaped rod 71 and fixed to the opposite surface of the sliding block 72 and the T-shaped rod 71;

[0053] Extrusion rack rods 74, six extrusion rack rods 74 are provided and every two are symmetrically fixed to the bottom surface of the sliding block 72, one side of each extrusion rack rod 74 is meshedly connected with a positioning gear 75, and two adjacent positioning gears 75 are coaxially fixedly arranged at the rotating shaft of the positioning rod 6;

[0054] It should be noted that when the metal tube is not positioned and installed, the three sliding blocks 72 are all located at the outermost periphery of the rotating ring 4 due to the elastic force of the compression spring 73, that is, the end of the extrusion rack rod 74 is farthest from the rotating ring 4, and the end of the three positioning rods 6 away from the rotating ring 4 is moved closer to the central axis of the rotating ring 4 through the meshing action of the extrusion rack rod 74 and the positioning gear 75;

[0055] When the metal tube is positioned and installed, one end of the metal tube is inserted from the center of the movable panel 3 until the outer surface of the metal tube contacts and squeezes the surface of the positioning rod 6. At this time, the three positioning rods 6 all rotate toward the periphery of the rotating ring 4, and the positioning gear 75 rotates accordingly. Through the meshing transmission between the positioning gear 75 and the extrusion rack rod 74, the sliding block 72 moves on the T-bar 71 toward the outer surface of the rotating ring 4, and drives the compression spring 73 to be compressed. At this time, through the reverse elastic force of the compression spring 73, the metal tube can be stably positioned and installed between the three positioning rods 6 in an extruded manner.

[0056] Further Figure 1 , Figure 2 , Figure 3 , Figure 5 , Figure 7 , Fig. 9 and Fig.10 As shown, it is worth to explain in detail that the clamping mechanism 11 includes a rotating ring 111, the rotating ring 111 is provided with two inner walls which are symmetrically mounted on the rotating ring 4, the outer surface of the rotating ring 111 is provided with three symmetrically distributed extrusion grooves 112, and the inner wall of each extrusion groove 112 is provided with an extrusion column 113 fixed to the outer surface of the clamping rod 8;

[0057] Push rods 114, three push rods 114 are provided and are respectively fixed to the outer surface of the sliding block 72, two symmetrically distributed clamping rods 115 are fixed to the end of each push rod 114, a push ring 116 is fixed to the end of the clamping rod 115, and a rotating column 117 fixed to the outer surface of the rotating ring 111 is provided inside the push ring 116;

[0058] It should be noted that when the metal tube is installed by center insertion extrusion positioning, the sliding block 72 drives the push rod 114 to move synchronously toward the outer surface of the rotating ring 4, and drives the clamping rod 115 and the push ring 116 to move synchronously. At this time, the pushing ring 116 pushes the rotating column 117, so that the rotating ring 111 rotates at a small angle on the inner wall of the rotating ring 4. At this time, the extrusion groove 112 squeezes the extrusion column 113, so that the clamping rod 8 moves toward the center of the rotating ring 4 at the inner wall of the rotating ring 4, that is, drives the installation frame 9 and the clamping rod 10 inside the installation frame 9 to move synchronously toward the center, so that multiple clamping rods 10 synchronously perform compression and positioning processing on the surface of the metal tube, and cooperate with the extrusion positioning effect of the three positioning rods 6, thereby effectively improving the convenience of stable installation of the metal tube at the center of the inner wall of the rotating ring 4.

[0059] Further Figure 1 , Figure 2 and Figure 4 As shown, it is worth to explain in detail that the bottom top surface of the movable panel 3 is provided with a travel mechanism 12, the travel mechanism 12 comprises a fixed rail 121, two fixed rails 121 are provided and symmetrically fixed to the bottom top surface of the operating table 1, the movable panel 3 is slidably mounted on the inner walls of the two fixed rails 121, and the bottom top surface of the movable panel 3 is installed with a servo motor 122;

[0060] A traveling gear 123, which is disposed above one of the fixed rails 121 and is coaxially connected to the output end of the servo motor 122, and the top surface of the fixed rail 121 is provided with teeth meshing with the traveling gear 123;

[0061] It should be noted that, driven by the servo motor 122, the traveling gear 123 rotates synchronously, and through the meshing transmission between the traveling gear 123 and the teeth, the movable panel 3 moves smoothly within the two fixed rails 121, so as to accurately move the cutting position of the double-positioned metal pipe to below the laser beam emitting tube of the laser saw 2, thereby effectively improving the cutting accuracy during subsequent laser-guided sawing.

[0062] Further Figure 1 , Figure 3 and Figure 8As shown, it is worth to explain in detail that the inner walls of the two fixed rails 121 are slidably connected with the material receiving panel 13, and the outer surface of the material receiving panel 13 close to the movable panel 3 is fixed with a fan-shaped material receiving ring 14;

[0063] It should be noted that a pull ring is provided on the outer surface of the receiving panel 13 away from the fan-shaped receiving ring 14, which is used to improve the convenience of sliding the receiving panel 13 in the two fixed rails 121, so that the fan-shaped receiving ring 14 can be smoothly moved to the laser beam emitting tube, and the metal pipe material cut by the laser-guided saw can be received and processed, thereby avoiding the metal pipe from falling and being damaged after cutting, thereby improving the safety of the metal pipe during falling to a certain extent.

[0064] This embodiment has the following working process: when laser-guided sawing is performed on the metal tube, the metal tube to be processed is first inserted from the center of the rotating ring 4 until the outer surface of the metal tube is squeezed with the three positioning rods 6 and the ends of the three positioning rods 6 are tangent to the surface of the metal tube. At this time, the end of the metal tube is positioned and installed on the central axis of the rotating ring 4 in an extruded manner through the setting of the extrusion positioning mechanism 7. At the same time, through the mutual cooperation of the extrusion positioning mechanism 7 and the clamping mechanism 11, the multiple clamping rods 10 move synchronously toward the center of the rotating ring 4, thereby performing a clamping treatment on the circumferential outer surface of the metal tube, forming a double positioning treatment of the metal tube, namely, the extrusion positioning of the three positioning rods 6 and the clamping positioning of the multiple clamping rods 10, thereby effectively improving the convenience of positioning and installation and the positioning stability of the metal tube before laser-guided sawing;

[0065] After the metal pipe is double-positioned and installed, the moving panel 3 is then driven by the traveling mechanism 12 to move on the top surface of the operating table 1, so that the cutting position of the metal pipe is accurately moved to below the laser beam emitting tube of the laser sawing device 2, thereby effectively improving the cutting accuracy during the subsequent laser-guided sawing;

[0066] By starting the laser saw 2 and the rotating motor 53 in the rotary cutting mechanism 5, the laser saw 2 generates a high-temperature laser beam, and at the same time the rotating ring 4 drives the metal tube that has been double-positioned to rotate, so that the high-temperature laser beam is subjected to a rotationally guided sawing process from the outer surface of the metal tube. The laser cutting process of the metal tube by rotary cutting can effectively improve the accuracy of the cutting surface of the metal tube.

[0067] Embodiment 2:

[0068] Based on the first embodiment, Figure 6 , Figure 7 , Fig. 9 and Fig.10As shown, it is worth to explain in detail that the clamping rod 8 includes a clamping sleeve 81 and a clamping sleeve rod 82, the clamping sleeve rod 82 is slidably mounted on the inner wall of the clamping sleeve 81, the extrusion column 113 is fixed to the outer surface of the clamping sleeve 81, the end of the clamping sleeve rod 82 is fixed to the surface of the mounting frame 9, and the clamping sleeve 81 is provided with a compression spring 15 fixed to the opposite surfaces of the clamping sleeve rod 82 and the clamping sleeve 81;

[0069] It should be noted that the clamping rod 8 is arranged in two sections, and is kept in a tensioned state by a compression spring 15. When the compression mechanism 11 drives the clamping rod 8 to move toward the center of the rotating ring 4 in the rotating ring 4, the clamping sleeve 81 drives the clamping sleeve rod 82 to move synchronously. At this time, multiple clamping rods 10 can be clamped by the clamping sleeve 81 and the clamping sleeve rod 82 in a synchronous movement manner, and the clamping sleeve rod 82 can reversely compress the compression spring 15 in the clamping sleeve 81 to form a reverse compression, and the surface of the metal tube is compressed by the compression rod 10 to perform a certain degree of balance compensation. In addition, the two sections of the clamping rod 8 are retractable, and can also be used for double positioning installation of variable-diameter metal tubes, thereby improving the convenience of laser-guided sawing of variable-diameter metal tubes.

[0070] Further Figure 4 , Figure 7 , Fig. 9 and Fig.10 As shown, it is worth to explain in detail that the end of the clamping sleeve 82 away from the mounting frame 9 is fixed with a balancing rod 16 penetrating the clamping sleeve 81 and the sliding block 72, the outer surface of the clamping sleeve 81 is provided with an abutment block 17 which is slidably sleeved on the outer surface of the balancing rod 16, and the outer surface of the balancing rod 16 is provided with a clamping spring 18 which is fixed to the opposite surface of the abutment block 17 and the sliding block 72;

[0071] It should be noted that, through the elastic force of the clamping spring 18, the abutment block 17 is ensured to be in a state of constant abutment when the clamping sleeve 81 moves in the rotating ring 4. The setting of the balance rod 16 can not only effectively guide the abutment block 17 for sliding, but also guide the clamping sleeve rod 82 for sliding when it moves in the reverse direction, thereby improving the stability of the movement of the clamping sleeve rod 82.

[0072] In summary, it can be known from the two embodiments that: through the cooperation between the extrusion positioning mechanism 7 and the clamping mechanism 11, the three positioning rods 6 perform extrusion positioning on the end surface of the metal tube, and at the same time, the multiple clamping rods 10 synchronously move toward the center of the rotating ring 4, thereby performing a compression process on the circumferential outer surface of the metal tube, forming a compression positioning of the metal tube, that is, completing the double positioning and installation process of the metal tube, thereby effectively improving the convenience of positioning and installation and the positioning stability of the metal tube before laser-guided sawing;

[0073] The moving panel 3 is driven by the traveling mechanism 12 to move on the top surface of the operating table 1, so that the cutting position of the metal pipe is accurately moved to below the laser beam emitting tube of the laser sawing device 2, thereby effectively improving the cutting accuracy during the subsequent laser guided sawing. By starting the laser sawing device 2 and the rotating motor 53 in the rotary cutting mechanism 5, the laser sawing device 2 generates a high-temperature laser beam, and at the same time, the rotating ring 4 drives the metal pipe that has been double-positioned to rotate, so that the laser beam generated by the high temperature performs a rotary guided sawing process from the outer surface of the metal pipe. The laser cutting process of the metal pipe by rotary cutting can effectively improve the flatness of the cutting surface of the metal pipe.

[0074] The clamping rod 8 is arranged in two sections, and can be clamped by the clamping sleeve 81 and the clamping sleeve rod 82 in a synchronous motion, and the clamping sleeve rod 82 can reversely compress the clamping spring 15 in the clamping sleeve 81 to form reverse compression, and the surface of the metal tube is clamped by the clamping rod 10 to perform a certain degree of balance compensation. In addition, the two sections of the clamping rod 8 are retractable, and can also be used for double positioning installation of variable-diameter metal tubes, thereby improving the convenience of laser-guided sawing of variable-diameter metal tubes.
