Detailed Implementation

[0020] This utility model provides a pipe cutting machine base frame. To make the purpose, technical solution, and effects of this utility model clearer and more explicit, the following describes this utility model in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain this utility model and are not intended to limit the scope of protection of this utility model.

[0021] Please see Figure 1 and Figure 2This utility model provides a pipe cutting machine base frame, including a side-mounted bed, multiple mounting side seats 13 disposed on the left side of the side-mounted bed, multiple reinforcing side seats 14 disposed on the right side of the side-mounted bed, a support seat 15 disposed between adjacent mounting side seats 13 and reinforcing side seats 14, and a gantry frame 2 spanning the side-mounted bed and the support seat 15; the side-mounted bed has multiple first cable routing ports 111 and second cable routing ports 121 disposed along its length; the side-mounted bed also has a first exhaust dust removal port 122 penetrating its front and rear side walls, and the support seat 15 has a first exhaust dust removal port 122 penetrating its front and rear side walls. The second exhaust dust removal port 151 on the left and right side walls is connected to the first exhaust dust removal port 122 by an exhaust dust removal pipe (not shown in the figure); the mounting side seat 13 is used to install the centering follow-up mechanism, and multiple first wiring ports 111 correspond to the centering follow-up mechanism and are used to collect the lines of the corresponding centering follow-up mechanism to the rear side of the side hanging bed; the adjacent reinforced side seats 14 are used to set up the unloading mechanism, and multiple second wiring ports 121 correspond to the unloading mechanism and are used to collect the lines of the corresponding unloading mechanism to the rear side of the side hanging bed.

[0022] In practical applications, after the centering follow-up mechanism is installed on the right side wall of the corresponding mounting side seat 13, the cable of the centering follow-up mechanism can be guided to the rear of the side hanging bed through the nearest first cable routing port 111 on the side hanging bed; similarly, after the unloading mechanism is assembled, the cable of the unloading mechanism can be guided to the rear of the side hanging bed through the nearest second cable routing port 121. In this embodiment, an electrical control cabinet is also set at the rear of the gantry 2, so the cable through the rear of the side hanging bed can be guided to the electrical control cabinet for centralized management.

[0023] Specifically, the laser cutting assembly is mounted on the gantry 2. A second exhaust dust removal port 151 is opened on the support base 15 below the gantry 2, making the second exhaust dust removal port 151 as close as possible to the laser cutting assembly. The exhaust dust removal pipe works in conjunction with the exhaust dust removal mechanism to directly suck up the metal dust generated during the laser cutting process, effectively reducing the spread of dust in the workshop, improving the working environment, and protecting the health of operators. In addition, in this embodiment, the second exhaust dust removal port 151 serves as an air inlet, and the first exhaust dust removal port 122 serves as an air outlet. The exhaust dust removal mechanism can be designed to be located at the rear of the equipment, or led out of the workshop through a pipe, with only the exhaust pipe exposed, which optimizes the dust removal path and improves the aesthetics of the equipment.

[0024] The aforementioned base frame, by opening multiple first wiring ports 111 and second wiring ports 121 at corresponding positions on the side-mounted bed, coordinates with the positions of the centering follow-up mechanism and the unloading mechanism, facilitating centralized processing of the wiring of the aforementioned mechanisms; in addition, the provided first exhaust dust port 122, second exhaust dust port 151, and exhaust dust pipe can effectively capture metal dust generated during laser cutting, reduce the spread of dust in the workshop, improve the working environment, and ensure the health and safety of operators.

[0025] In some embodiments, the side-mounted machine bed includes a first sub-frame 11 and a second sub-frame 12 disposed on one side of the first sub-frame 11 and spliced ​​together; a plurality of mounting side seats 13 are disposed on the front side of the first sub-frame 11, a plurality of reinforcing side seats 14 are disposed on the front side of the second sub-frame 12, a support seat 15 is disposed on the front side of the second sub-frame 12, and the lower surface of the front side of the gantry 2 is fixedly connected to the upper surface of the support seat 15; the first exhaust dust removal port 122 is disposed away from the cutting area of ​​the gantry 2. Specifically, the first sub-frame 11 and the second sub-frame 12 are mounted together by a precision mounting surface and fixed by fastening bolts. The splicing design of the first sub-frame 11 and the second sub-frame 12 is used to shorten the length of the side-mounted machine bed, providing convenience for subsequent large gantry milling operations. More specifically, the gantry 2 and the laser cutting assembly are surrounded by sheet metal to form a protective box. The inside of the protective box is the cutting area. Therefore, the first exhaust dust removal port 122 is set on the left side of the protective box, that is, the first exhaust dust removal port 122 is led out of the protective box.

[0026] In some embodiments, both the first subframe 11 and the second subframe 12 include a horizontal tube assembly 3 consisting of multiple horizontal tubes stacked and fixed together, and a reinforcing frame 4 disposed behind the horizontal tube assembly 3. The horizontal tube assembly 3 is composed of multiple horizontal tubes stacked together, and horizontal tubes of different heights can be selected for stacking according to the height of the side-mounted bed. The manufacturing process is simple and can be completed without cutting large-format panels, which helps to reduce manufacturing costs. The reinforcing frame 4 is provided to improve the structural rigidity of the side-mounted bed and to provide cable routing space, making full and reasonable use of the space layout of the base frame.

[0027] In some embodiments, the upper surface of the uppermost horizontal tube of the horizontal tube assembly 3 is provided with a first guide rail mounting strip 31 and a first rack mounting strip 32 extending along its length, and a second guide rail mounting strip 33 provided on its side and extending along its length. After the first sub-frame 11 and the second sub-frame 12 are spliced ​​into a side-mounted bed, the mounting surfaces of the first guide rail mounting strip 31, the first rack mounting strip 32, and the second guide rail mounting strip 33 are precision machined to ensure that the mounting surfaces of the first guide rail mounting strip 31, the first rack mounting strip 32, and the second guide rail mounting strip 33 on each of the first sub-frames 11 and the second sub-frames 12 are on the same plane, so that the first guide rail, the first rack, and the second guide rail are installed accurately, and the chuck assembly forms a side-mounted sliding connection with the first guide rail and the second guide rail, and the gear on the chuck assembly meshes with the first rack. The large gantry milling machine performs high-precision machining on the mounting surfaces of the first guide rail mounting strip 31, the first rack mounting strip 32, and the second guide rail mounting strip 33 on the first sub-carrier 11 and the second sub-carrier 12 in one operation. This improves the stability of the chuck assembly installation, making the chuck more stable during movement. Furthermore, the machine bed structure features a lightweight design. The side-mounted machine bed adopts a splicing design of the first sub-carrier 11 and the second sub-carrier 12. The large gantry milling machine performs high-precision machining on the guide rail and rack mounting surfaces on the first sub-carrier 11 and the second sub-carrier 12 in one operation, ensuring that all mounting surfaces are on the same plane. This improves the stability and accuracy of the chuck assembly installation, thereby guaranteeing the smoothness of the pipe cutting machine during operation.

[0028] Please see Figure 2 In some embodiments, the reinforcing frame 4 includes a reinforcing upper crossbeam 41, a reinforcing lower crossbeam 42 disposed below the reinforcing upper crossbeam 41, and multiple connecting vertical beams 43 for connecting the reinforcing upper crossbeam 41 and the reinforcing lower crossbeam 42; the bottom of the connecting vertical beams 43 has a wiring notch 44 near the horizontal tube assembly 3. The reinforcing upper crossbeam 41, the reinforcing lower crossbeam 42, and the connecting vertical beams 43 together form a more stable frame structure, significantly enhancing the rigidity and deformation resistance of the entire side-mounted bed. The wiring notch 44, designed to cooperate with the first wiring port 111 and the second wiring port 121, provides a more convenient wiring channel, standardizes the wiring route, is both aesthetically pleasing and improves safety, and also simplifies the maintenance and repair process.

[0029] Please see Figure 2 In some embodiments, the height of the reinforcing upper crossbeam 41 is lower than the height of the uppermost crossbeam in the crossbeam assembly 3; the upper surface of the reinforcing upper crossbeam 41 is used to support the Y-axis cable chain. The upper surface of the reinforcing upper crossbeam 41 serves as a support surface for the Y-axis cable chain, supporting its movement.

[0030] In the above-mentioned components, the horizontal pipes, the reinforcing upper horizontal beam 41, the reinforcing lower horizontal beam 42, and the connecting vertical beam 43 on the horizontal pipe assembly 3 are all made of rectangular or square steel pipes, which have sufficient structural strength and rigidity. All components within the first subframe 11 and the second subframe 12 are fixed by welding, resulting in good overall structural strength.

[0031] Please see Figure 2 In some embodiments, the reinforcing upper crossbeam 41 is further provided with a third cable routing port 411 that runs through its upper and lower side walls. The number of the third cable routing ports 411 is the same as the number of Y-axis cable chains. Similarly, the cables of the Y-axis cable chains are guided into the interior of the reinforcing frame 4 through the third cable routing ports 411, which further facilitates centralized management of the lines.

[0032] In some embodiments, the lower surfaces of the reinforcing lower crossbeam 42, the mounting side seat 13, the reinforced side seat 14, and the support seat 15 are all provided with adjusting feet 5 (the figure indicates the adjusting feet 5 mounting plate); the number of adjusting feet 5 provided on the reinforcing lower crossbeam 42 is the same as the number of connecting vertical beams 43, and they correspond one-to-one with each connecting vertical beam 43. Specifically, the height of each adjusting foot 5 can be finely adjusted to ensure that all positions of the long side-mounted bed are on the same horizontal plane. More specifically, there are twenty-four adjusting feet 5, with pre-drilled holes for ground stake connection. After the machine is debugged, expansion bolts need to be driven to connect it to the ground to ensure the stability of the machine during long-term operation.

[0033] In some embodiments, the gantry 2 includes a first vertical beam 21 fixedly connected to the upper surface of the horizontal tube assembly 3, a second vertical beam 22 fixedly connected to the upper surface of the support base 15, and a top beam 23 connecting the upper parts of the first vertical beam 21 and the second vertical beam 22. The gantry 2 is welded from several rectangular tubes and plates, and is mainly used to provide a high-precision mounting surface for the guide rail mounting strip and rack mounting strip. It cooperates with the drive source of the laser cutting assembly to realize the reciprocating movement of the laser cutting assembly along the X-axis and Z-axis directions.

[0034] In summary, this utility model, by opening multiple first wiring ports 111 and second wiring ports 121 at corresponding positions on the side-mounted bed, coordinates with the positions of the centering follow-up mechanism and the unloading mechanism, facilitating centralized processing of the wiring of the aforementioned mechanisms. In addition, the provided first exhaust dust port 122, second exhaust dust port 151, and exhaust dust pipe can effectively capture metal dust generated during laser cutting, reduce the spread of dust in the workshop, improve the working environment, and ensure the health and safety of operators.
