Description

Technical Field

[0001] The utility model relates to the technical field of laser cutting machines, in particular to a welded steel crossbeam of a laser cutting machine. Background Art

[0002] The crossbeam is an important part of the laser cutting machine.

[0050] In order to better explain the present invention and facilitate understanding, the present invention is described in detail below through specific implementation modes in conjunction with the accompanying drawings.

[0051] It should be noted that all directional indications (such as up, down, left, right, front, back...) in the embodiments of the present invention are only used to explain the relative position relationship, movement status, etc. between the components under a certain specific posture (as shown in the accompanying drawings). If the specific posture changes, the directional indication will also change accordingly.

[0052] In addition, in the present invention, the descriptions of "first", "second", etc. are only used for descriptive purposes and cannot be understood as indicating or implying their relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "first" or "second" may explicitly or implicitly include at least one of the features. In the description of the present invention, the meaning of "plurality" is at least two, such as two, three, etc., unless otherwise clearly and specifically defined.

[0053] In the present invention, unless otherwise clearly specified and limited, the terms "connection", "fixation", etc. should be understood in a broad sense. For example, "fixation" can be a fixed connection, a detachable connection, or an integral connection; "connection" can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, and it can be the internal connection of two elements or the interaction relationship between two elements, unless otherwise clearly defined. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0054] See also Figure 1 The utility model provides a welded steel crossbeam of a laser cutting machine, which comprises a base 1, a first support plate 2, a second support plate 3, an inner support assembly and a plurality of vertical plates 4; the first support plate 2 and the second support plate 3 are mirror-welded to the top of the base 1; the first support plate 2 and the second support plate 3 form a cavity; the inner support assembly is arranged in the cavity, and the inner support assembly abuts against the wall of the cavity; the plurality of vertical plates 4 are arranged in parallel along a first direction, which is the length direction of the first support plate 2; the inner support assembly is clamped with the vertical plate 4; the first support plate 2 and the second support plate 3 are both welded to the vertical plate 4.

[0055] The first support plate 2 and the second support plate 3 are combined and spliced ​​into the beam body. The base 1 is reserved with holes for installing the reducer and fixing holes for the slider. In addition, the height of the beam increases with the z-axis stroke of the laser cutting machine to improve the adaptability to thick plate processing. The vertical plate 4 close to the free end of the beam body serves as a sealing plate to improve the sealing, aesthetics and flatness of the welded steel beam. Flatness means that it can effectively prevent operators from being injured by bumping the free end of the beam body.

[0056] The internal support assembly is set in the beam body to support the beam body from the inside. Compared with the traditional square-mouth beam and I-beam, the internal support assembly greatly enhances the overall rigidity of the welded steel beam, improves the adaptability of the laser cutting machine to cut large-format and thick plates, and thus improves the processing accuracy of the plate. The welded steel beam greatly reduces the manufacturing difficulty and processing cycle of the beam, creating the possibility for mass production of the equipment.

[0057] The inner support assembly is clamped with the vertical plate 4, and the first support plate 2 and the second support plate 3 are both welded to the vertical plate 4, so that the force acting on the beam body can be effectively distributed to the vertical plate 4, and then distributed to the inner support assembly, which can further enhance the overall rigidity of the welded steel beam and improve the adaptability of the laser cutting machine to process large plates.

[0058] The inner support assembly supports the beam body from the inside, which can reserve sufficient installation space for the mounting parts and their matching parts on the beam body, achieve reasonable mechanical assembly performance, and improve the operating stability of the whole equipment. Figure 2 As shown, in this embodiment, a guide rail mounting platform 22 and a gear mounting platform 23 are provided on the first support plate 2, and the guide rail mounting platform 22 and the gear mounting platform 23 are used to install the cutting head and enable the cutting head to move along the first direction. Since the inner support assembly is arranged inside the crossbeam body, it will not interfere with the installation of the guide rail mounting platform 22 and the gear mounting platform 23. Compared with the method of directly erecting a column at the bottom of the crossbeam, the welded steel crossbeam of the utility model will not interfere with the mounting parts and their matching parts on the crossbeam, which greatly facilitates the installation of the mounting parts and their matching parts and simplifies the installation process.

[0059] like Figure 3 and Figure 4 As shown, the inner support assembly includes a middle plate 5, a pair of top plates 6 and a pair of bottom plates; the pair of top plates 6 are connected to the top sides of the vertical plate 4 in a one-to-one manner; the middle plate 5 is connected to the middle of the vertical plate 4; the pair of bottom plates are connected to the bottom sides of the vertical plate 4 in a one-to-one manner; the two sides of the middle plate 5, the top plate 6 and the bottom plate are all connected to the two sides of the cavity in a one-to-one manner; the top surface of the top plate 6 and the bottom surface of the bottom plate are connected to the top surface and the bottom surface of the cavity in a corresponding manner. In this embodiment, the middle plate 5, the top plate 6 and the bottom plate are all formed by bending sheet metal parts, and the pair of top plates 6 are arranged at the same height. When connected to the vertical plate 4, the splicing of the pair of top plates 6 is also completed, which can effectively ensure the force balance on both sides of the vertical plate 4 and improve the overall stiffness of the welded steel beam. The pair of bottom plates are set in analogy with the pair of top plates 6, and will not be repeated. Optionally, after the middle plate 5, the top plate 6 or the bottom plate is connected to the vertical plate 4, it can be welded again to further improve the structural strength. All three layers of plates can abut against the side surfaces of the cavity, facilitating the transmission of the internal forces of the welded steel beam; at the same time, the top surface of the middle plate 5 and the bottom surface of the bottom plate correspond to abut against the top and bottom surfaces of the cavity, so that the internal support assembly can be firmly engaged in the beam body, further enhancing the convenience of the transmission of the internal forces of the welded steel beam.

[0060] Further, the middle plate 5, the top plate 6 and the bottom plate are all provided with side flange plates 9 on the side facing the side of the cavity; the side flange plates 9 abut against the side of the cavity; the top of the top plate 6 is provided with a first L-shaped plate 63; the first L-shaped plate 63 abuts against the top surface of the cavity; the bottom of the bottom plate is provided with a second L-shaped plate; the second L-shaped plate abuts against the bottom surface of the cavity. The side flange plates 9, the first L-shaped plate 63 and the second L-shaped plate can increase the contact area between the inner support assembly and the cavity wall, and further improve the support strength of the inner support assembly to the beam body. Alternatively, the side flange plates 9 are provided on both sides of the top plate 6, and the connection of a pair of top plates 6 is fixedly connected by a first connecting plate, and the first connecting plate abuts against the top surface of the cavity. The side flange plates 9 are provided on both sides of the bottom plate, and the connection of a pair of bottom plates is fixedly connected by a second connecting plate, and the second connecting plate abuts against the bottom surface of the cavity. The first connecting plate and the second connecting plate are plate bodies, which are used to connect and support the inner support assembly.

[0061] Secondly, a plurality of half-M-shaped beams 62 are provided on the top plate 6 and the bottom plate; a plurality of M-shaped beams 52 are provided on the middle plate 5. The half-M-shaped beams 62 on the bottom plate are similar and will not be described in detail. Optionally, a through hole can be provided at the beam center of the M-shaped beam 52 as a weight-reducing hole.

[0062] like Figure 5 As shown, the vertical plate 4 includes a vertical plate body 41, a pair of upper flange plates 42 and a pair of lower flange plates 43; the pair of upper flange plates 42 are vertically arranged on both sides of the top of the vertical plate body 41 in a one-to-one correspondence; the upper flange plates 42 are welded to the top surface of the cavity; the pair of lower flange plates 43 are vertically arranged on both sides of the bottom end of the vertical plate body 41 in a one-to-one correspondence; the lower flange plates 43 are welded to the bottom surface of the cavity; the middle plate 5, the top plate 6 and the bottom plate are all clamped with the vertical plate body 41. Welding the upper flange plate 42 to the top surface of the cavity and welding the lower flange to the bottom surface of the cavity, in conjunction with the side flange plates 9, the first L-shaped plate 63 and the second L-shaped plate of the inner support assembly, can further enhance the firmness of the inner support assembly installed in the cavity, thereby further enhancing the transmission of the force and improving the rigidity of the welded steel beam.

[0063] Furthermore, the vertical plate body 41 is provided with a middle slot 411, a pair of upper slots 412 and a pair of lower slots 413; the middle plate 5 is provided with a notch 51; the middle slot 411 is engaged with the notch 51 of the middle plate 5; the top plate 6 is provided with a first avoidance slot 61; the upper flange plate 42 can pass through the first avoidance slot 61 so that the upper slot 412 is engaged with the top plate 6; the bottom plate is provided with a second avoidance slot; the lower flange plate 43 can pass through the second avoidance slot so that the lower slot 413 is engaged with the bottom plate. In this embodiment, the middle slot 411, the upper slot 412, the lower slot 413 and the notch 51 are all straight slots. The middle slot 411 is arranged in the middle of the vertical board 4. Since the structural strength of the middle of the vertical board 4 is higher than that of the edge, the length dimension of the middle slot 411 can be set larger, so that the middle board 5 can be inserted into the middle slot 411 as a complete board. Since the upper slot 412 and the lower slot 413 are located at the edge of the vertical board body 41, the structural strength of the edge is relatively low. The utility model adopts a splicing method to insert a pair of top boards 6 from both sides of the vertical board body 41, which can effectively shorten the length dimension of the pair of upper slots 412, thereby ensuring the support strength of the vertical board body 41. The lower slot 413 is arranged in the same way as the upper slot 412, and will not be described in detail.

[0064] In this embodiment, the first avoidance groove 61 is a rectangular groove, and the length and width of the first avoidance groove 61 are correspondingly larger than the length and width of the upper flange plate 42, so that a pair of top panels 6 can pass through the vertical plate 4 and be embedded in the vertical plate 4, thereby ensuring the stability of the structure. The first avoidance groove 61 is used to avoid the upper flange plate 42. The principle of the second avoidance groove is the same as that of the first avoidance groove 61, and will not be repeated.

[0065] Secondly, a plurality of threading holes 414 are provided on the vertical plate body 41. The oil circuit of the laser cutting machine can be routed in the threading holes 414, which improves the flexibility of the laser cutting machine wiring, and the threading holes 414 further reduce the weight of the welded steel beam.

[0066] See again Figure 2 , along the first direction, a plurality of plug welding holes 21 are opened on the first support plate 2; the plug welding holes 21 are welded to the vertical plate 4. The positions of the plurality of plug welding holes 21 correspond to the positions of the plurality of vertical plates 4 one by one, and the connection strength between the first support plate 2 and the vertical plate 4 is further strengthened by the plug welding holes 21.

[0067] See again Figure 1 In the cross section perpendicular to the first direction, the first support plate 2 and the second support plate 3 are in a bow shape; the vertical plate 4 is in an I-shaped shape. The shape and size of the cavity after the first support plate 2 and the second support plate 3 are spliced ​​are compatible with the shape and size of the vertical plate 4.

[0068] In addition, the welded steel cross beam also includes a reinforcing rib plate 8; the base 1 and the first support plate 2 are vertically welded to the reinforcing rib plate 8. The reinforcing rib plate 8 can enhance the transmission of the force between the base 1 and the first support plate 2, thereby enhancing the supporting strength of the welded steel cross beam and extending its service life.

[0069] It should be understood that the above description of the specific embodiments of the utility model is only for illustrating the technical route and features of the utility model, and its purpose is to enable those skilled in the art to understand the content of the utility model and implement it accordingly, but the utility model is not limited to the above specific implementation methods.
