Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of laser cutting, in particular to a laser cutting machine bed body and a laser cutting machine. BACKGROUND

[0002] The laser cutting machine is a machine that emits laser from a laser, focuses into a high-power density laser beam through an optical system, and makes the laser beam irradiate to the workpiece surface, so that the workpiece reaches the melting point or boiling point to complete the cutting. The laser cutting machine replaces the traditional mechanical cutter with a high-energy light beam. Compared with the traditional mechanical cutting machine, it not only has high precision, smooth cutting edge without burr, and no need for further processing, but also cuts quickly, which is more than 100 times faster than traditional wire cutting.

[0003] The bed body of the existing laser cutting machine is generally provided with support bars arranged at uniform intervals, and there is a gap between the support bars. The metal slag generated during the cutting process is easy to adhere to the support bars, causing cleaning difficulty and affecting subsequent cutting precision.

[0004] The existing cleaning method is generally to clean the support bars installed on the bed body one by one by hand. This cleaning method is low in efficiency. If the support bars are disassembled for cleaning, it is not only time-consuming and laborious, but also easy to cause the positioning accuracy of the support bars to decrease due to frequent disassembly and assembly. When there is little residue, disassembling and cleaning reduces the efficiency (disassembly, assembly and cleaning all require a lot of time), and is easy to cause the support bars to bend and deform, affecting the overall structural stability and cutting precision. When there is a lot of residue, disassembly and cleaning are more difficult.

[0005] If the support bars are directly replaced, on the one hand, the cost is high, and on the other hand, in order to save cost, the support bars are generally used to the extent that they cannot be used any more before being replaced, which causes the cutting precision to gradually decrease in the early stage, affecting the processing quality. With the accumulation of residue, on the one hand, the precision is reduced, and on the other hand, scratches are generated on the cutting body with smoothness requirement, affecting the product quality.

[0015] Further, the first cross beam and the second cross beam are respectively connected with vertical sliding tables of vertical sliding assemblies at both ends, and the vertical sliding assemblies are installed on horizontal sliding tables of horizontal sliding assemblies.

[0016] Further, the vertical sliding assembly comprises a vertical guide rail, a vertical sliding table and a lifting driving mechanism, the vertical guide rail is vertically fixed on the horizontal sliding table, and the lifting driving mechanism drives the vertical sliding table to slide up and down along the guide rail.

[0017] Further, the horizontal sliding assembly comprises a horizontal guide rail, a horizontal sliding table and a horizontal driving mechanism, the guide rail is arranged along the length direction of the machine tool, and the horizontal driving mechanism drives the horizontal sliding table to move horizontally along the horizontal guide rail.

[0043] Embodiments

[0044] Reference Figures 1-3In one aspect, the application provides a laser cutting machine bed 7, comprising a first bed frame and a second bed frame, the first bed frame comprising first cross beams 9 arranged oppositely and parallel to each other, the first cross beams 9 being capable of adjusting vertical position and horizontal position, the first cross beams 9 being provided with a first turnover mechanism 14, and the output end of the first turnover mechanism 14 being provided with a first support bar 18;

[0045] The second bed frame comprises second cross beams 10 arranged oppositely and parallel to each other, the second cross beams 10 being capable of adjusting vertical position and horizontal position, the second cross beams 10 being provided with a second turnover mechanism 17, and the output end of the second turnover mechanism 17 being provided with a second support bar 20, the first support bar 18 and the second support bar 20 being in a vertical state when the first turnover mechanism 14 and the second turnover mechanism 17 are in a first state, and the first support bar 18 and the second support bar 20 being in a horizontal state when the first turnover mechanism 14 and the second turnover mechanism 17 are in a second state.

[0046] When working normally, the first cross beams 9 and the second cross beams 10 are in the same plane, the first support bars 18 and the second support bars 20 are in a vertical state, and adjacent first support bars 18 and second support bars 20 are closely attached to form a stable support structure, which jointly supports the plate to be processed, and a plurality of first support bars 18 and second support bars 20 are arranged equidistantly along the length direction of the cross beams, so as to ensure that the supporting surface is uniformly stressed;

[0047] When the first support bar 18 and the second support bar 20 accumulate too much cutting residue or need to be replaced and maintained, the first support bar 18 and the second support bar 20 are turned to the horizontal state in turn. Taking the turning of the first support bar 18 as an example, first, the position of the first cross beam 9 is adjusted, the first cross beam 9 is raised to a certain height, then the first turning mechanism 14 is started, the first support bar 18 is smoothly rotated from the vertical state to the horizontal state, so that one side with residue faces upward and the other side faces downward, then the first cross beam 9 is driven to move horizontally, so that each first support bar 18 is located on the second support bar 20, then the first cross beam 9 is driven to move downward, so that the lower side of the first support bar 18 is attached to the top of the second support bar 20, at this time the second support bar 20 is still in the vertical state, forming a temporary support point to ensure that the plate remains stable during residue removal, then the first support bar 18 is cleaned or replaced, after completion, it is turned back to the vertical state and the first cross beam 9 is reset; similarly, the second support bar 20 is processed in turn, the entire process does not need to be disassembled, greatly shortening the maintenance time and improving the equipment operation efficiency; through the turning operation, in the first aspect, the residue on the surface of the support bar is in the same plane, which is convenient for centralized cleaning and improves the cleaning efficiency; in the second aspect, through the attachment, only one side of the support bar has residue and the other side is always clean, thereby providing the reliability and stability of the support surface and effectively avoiding the problem of uneven support or plate sliding caused by residue accumulation; in the third aspect, through the alternating turning, the other support bar is always in the vertical supporting state, thereby no additional support structure is needed to support the support bar to be removed, which guarantees the continuity and safety of the processing process; in the fourth aspect, the residue is not only in the same plane, but also only one side of the first support bar 18 or the second support bar 20 is processed each time, and the residue is always in the tooth part of the support bar, therefore, in the cleaning process, the residue forms evenly spaced strip-shaped residue, the extension direction of the strip-shaped residue is in the width direction of the machine tool, and in the length direction of the machine tool, the spacing distance of adjacent strip-shaped residues is relatively uniform, the cleaning path is more concentrated, which is convenient for the cleaning device to work efficiently along the fixed track, reduces the residual dead angle, improves the cleaning precision and speed, and in the fifth aspect, only one side of the support bar forms residue, which avoids double-sided pollution and reduces the cleaning difficulty.

[0048] In some embodiments, as shown in Figure 4 The first support bar 18 and the second support bar 20 are provided below with a plurality of support plates 8, the support plates 8 are perpendicular to the first support bar 18 and the second support bar 20, a limiting groove 19 is arranged on the support plate 8 in the middle, and the first support bar 18 and the second support bar 20 that are attached to each other are located in the same limiting groove 19.

[0049] When working normally, the top surface of the support plate 8 is in contact with the first support bar 18 and the second support bar 20 below to provide stable support for the first support bar 18 and the second support bar 20; when performing turnover maintenance, the first cross beam 9 and the second cross beam 10 are first driven to move synchronously and reciprocally horizontally, so that the first support bar 18 and the second support bar 20 are bent horizontally under the action of the limiting groove 19, thereby elastically deforming, so that a small gap is generated at the joint of the first support bar 18 and the second support bar 20, facilitating residue peeling and facilitating smooth turnover operation of the first support bar 18 and the second support bar 20, thereby avoiding structural jamming caused by residue adhesion.

[0050] In some embodiments, as shown in Figure 3 、 Figure 9 、 Figure 10 The first turnover mechanism 14 and the second turnover mechanism 17 are the same in structure, and each includes a mounting seat 1701, a mounting plate 1703 fixed on the mounting seat 1701, a half gear 1707 rotatably mounted on the mounting plate 1703, and a rack 1702 slidably mounted on the mounting seat 1701 and engaged with the half gear 1707. A fixed plate 1705 is mounted on one side of the half gear 1707. The rack 1702 is driven by the linear drive mechanism 16 to rotate the half gear 1707, thereby realizing turnover movement of the fixed plate 1705.

[0051] When working normally, the rack 1702 is in a first state driven by the linear drive mechanism 16, and at this time the half gear 1707 remains stationary and the fixed plate 1705 is in a vertical state, so that the fixed plate 1705 provides vertical support for the support bar, ensuring stable positioning of the plate during processing; when turnover is needed, the rack 1702 is moved to a second state under driving, pushing the half gear 1707 to rotate by 90 degrees and driving the fixed plate 1705 to change from vertical to horizontal, so that the support bar after turnover can be accurately dropped into the predetermined position in cooperation with the position movement of the cross beam.

[0052] Further, when working normally, a support seat (not shown in the figure) is arranged below the fixed plate 1705 and arranged along the length direction of the first bed frame and the second bed frame, for providing auxiliary support for the fixed plate 1705, enhancing the support rigidity and avoiding offset of the fixed plate 1705 caused by processing vibration; when the turnover operation is started, the first cross beam 9 and the second cross beam 10 are driven to move vertically, so that the fixed plate 1705 is out of contact with the support seat, reserving space for the rotation movement of the fixed plate 1705.

[0053] Further, a stop block (not shown in the figure) for limiting the stroke of the rack 1702 is arranged on the mounting plate 1703, so as to ensure reciprocating movement of the rack 1702 within a preset range, prevent the half gear 1707 from disengaging or the structure from being damaged caused by excessive displacement, and improve the repeated positioning accuracy of the turnover action.

[0054] Furthermore, a tilting angle limiting block is provided on the mounting plate 1703 to limit the tilting angle of the fixing plate 1705, preventing the fixing plate 1705 from exceeding the set angle during rotation, ensuring that it stops accurately in the vertical or horizontal working position, and improving the reliability and safety of the operation. For example, the tilting angle limiting block is a protruding post 1704 fixed on the mounting plate 1703, the position of which corresponds to the position of the fixing plate 1705 when the half gear 1707 rotates to the initial position, and the extreme position of the fixing plate 1705 when the half gear 1707 rotates 90 degrees.

[0055] Furthermore, to ensure the smooth and precise rotation of the half gear 1707, the half gear 1707 is rotatably mounted on the mounting plate 1703 via the bearing 1706. The outer ring of the bearing 1706 is fixedly connected to the mounting plate 1703, and the inner ring is sleeved on the rotating shaft of the half gear 1707, thereby achieving low-friction and high-precision rotational support.

[0056] Furthermore, the tooth profile of the meshing section between the half gear 1707 and the rack 1702 has been modified to reduce transmission impact, improve meshing smoothness, and extend the service life of the mechanism. For example, the linear drive mechanism 16 uses a servo electric cylinder, combined with high-precision grating ruler feedback, to achieve closed-loop control of the rack 1702 displacement, ensuring accurate and stable tilting angle.

[0057] In some embodiments, such as Figures 4-8 As shown, when both the first support bar 18 and the second support bar 20 are in a vertical state, adjacent first support bars 18 and second support bars 20 are tightly fitted together. At this time, the first support bars 18 and the second support bars 20 together form a continuous vertical support surface, ensuring that only one side of each support bar 18 and the second support bar 20 will always have residue adhering to it, while the tightly fitted side remains clean. This allows for rotation maintenance of the support bars, where the previously exposed adhesive surface can be flipped to face the cleaning equipment, while the previously clean adhesive surface is pressed against the other support bar, achieving stable support for the support bar to be cleaned. This prevents the adhesive surface from deforming or shifting due to pressure or vibration during cleaning, and allows for stable support without disassembly, forming a continuous cleaning working surface, improving cleaning efficiency and quality. Simultaneously, this design avoids residue adhering to both sides of the support bar, preventing the increased cleaning difficulty caused by the superposition of adhesive forces.

[0058] In some embodiments, such as Figures 3-4 As shown, the racks 1702 located on the same crossbeam are synchronously driven by the same drive mechanism.

[0059] To ensure the same rack 1702 movement of the beam is fully synchronized, to avoid the structure of different drive synchronization caused by interference or uneven stress, to ensure the coordination and stability of the turnover action. For example, the use of connecting rod 12 will be connected to the same servo cylinder drive end of the plurality of rack 1702, through the rigid transmission of connecting rod 12 to achieve synchronous reciprocating motion.

[0060] In some embodiments, as shown in Figures 3-4 The first cross beam 9, the second cross beam 10 is provided with support frame 11, the first cross beam 9, the second cross beam 10 is in the same horizontal plane, support frame 11 to the beam forms a stable support.

[0061] The first cross beam 9, the second cross beam 10 is in the normal working state, the top of the support frame 11 and the bottom of the beam are closely combined, providing reliable support, preventing the beam from bending or vibrating under the action of load, ensuring the rigidity and stability of the overall structure.

[0062] Further, the two ends of the support plate 8 and the support seat can be fixed on the support frame 11, and the bottom of the support frame 11 is fixedly connected with the ground, so as to effectively share the load stress of the cross beam during the turnover process, and improve the rigidity and stability of the overall structure.

[0063] In some embodiments, as shown in Figure 3 , Figure 11 The first cross beam 9, the second cross beam 10 is provided with support frame 11, the first cross beam 9, the second cross beam 10 is in the same horizontal plane, support frame 11 to the beam forms a stable support.

[0064] When the first cross beam 9, the second cross beam 10 needs to adjust the vertical position, the vertical sliding assembly 13 drives the vertical sliding table 1303 on it to move in the vertical direction, so as to realize the accurate adjustment of the overall height of the cross beam and the support bar, when the first cross beam 9, the second cross beam 10 needs to adjust the horizontal position, the horizontal sliding assembly 15 drives the vertical sliding assembly 13 to move in the horizontal direction, so as to realize the horizontal position adjustment of the overall cross beam and the support bar, and then complete the smooth switching between the first support bar 18 and the second support bar 20 in the state of close contact and the turnover cleaning state.

[0065] In some embodiments, as shown in Figure 3 , Figure 11 The vertical sliding assembly 13 includes vertical guide rail 1302, vertical sliding table 1303 and lifting drive mechanism 1301, the vertical guide rail 1302 is vertically fixed on the horizontal sliding table 1503, and the lifting drive mechanism 1301 drives the vertical sliding table 1303 to slide up and down along the guide rail.

[0066] The aforementioned lifting drive mechanism 1301 drives the vertical sliding table 1303 to reciprocate along the vertical guide rail 1302, thereby achieving precise lifting and lowering of the crossbeam. This enables dynamic adjustment of the overall height of the crossbeam and the support bar, ensuring the smoothness of the first support bar 18 and the second support bar 20 in contact and the smoothness of the support state switching. For example, the lifting drive mechanism 1301 can adopt a servo motor combined with a ball screw structure, and the vertical guide rail 1302 can adopt a high-precision linear guide rail to ensure smooth lifting and accurate positioning.

[0067] In some embodiments, such as Figure 3 , Figure 11 As shown, the transverse sliding assembly 15 includes a transverse guide rail 1502, a transverse sliding table 1503, and a horizontal drive mechanism 1501. The transverse guide rail 1502 is arranged along the length of the machine tool, and the horizontal drive mechanism 1501 drives the transverse sliding table 1503 to move laterally along the transverse guide rail 1502.

[0068] The aforementioned horizontal drive mechanism 1501 drives the transverse sliding table 1503 to reciprocate along the transverse guide rail 1502, thereby achieving precise transverse movement of the entire beam and support bar, ensuring the smoothness of the first support bar 18 and the second support bar 20 in the contact state and the switching of the support state. For example, the horizontal drive mechanism 1501 can be a servo electric cylinder, and the transverse guide rail 1502 can be a single or double row of high-rigidity linear guide rails to ensure smooth transverse operation and accurate positioning.

A gantry frame 2 slides on the processing body 1, a first sliding table 3 is installed on the gantry frame 2, a laser cutting head 5 is installed on the first sliding table 3, and a slag removal head 6 is installed on the second sliding table 4.

[0070] The machining main body 1 is arranged around the bed body 7, the gantry 2 slides along the length direction of the bed body 7, drives the first sliding table 3 and the second sliding table 4 to move synchronously, realizes the accurate positioning of the laser cutting head 5 and the slag removal head 6 above the workpiece, the mechanism cutting head can independently slide along the length direction of the first sliding table 3, completes the multi-angle cutting operation of the workpiece, the slag removal head 6 can independently slide along the length direction of the second sliding table 4, completes the automatic cleaning operation of the residual slag after cutting, and improves the machining efficiency and surface quality. When the cutting operation is performed, the first supporting strip 18 and the second supporting strip 20 are in the adhering state, and the workpiece is supported together, so that the material is stable and does not deviate in the cutting process; when the cutting is completed and enters the cleaning stage, the first supporting strip 18 and the second supporting strip 20 are separated and sequentially switched to the turnover cleaning state, when the first supporting strip 18 is switched to the cleaning state, the first supporting strip 18 is in the horizontal state and is pressed on the second supporting strip 20, the second supporting strip 20 is in the vertical state to support the first supporting strip 18, at this time, the first supporting strip 18 is located in the same plane, and the side with the residual slag faces the slag removal head 6, then when the slag removal head 6 moves along the second sliding table 4, the surface of the first supporting strip 18 is cleaned efficiently; similarly, when the second supporting strip 20 is switched to the cleaning state, the second supporting strip 20 is horizontally pressed on the first supporting strip 18, and the first supporting strip 18 is vertically supported, so that the residual slag of the second supporting strip 20 faces the slag removal head 6, and the complete cleaning is completed one by one, the whole process does not need manual intervention, realizes the automatic collaborative operation of cutting and slag removal, and effectively improves the equipment integration and operation reliability.
