Description

Technical Field

[0001] The invention belongs to the technical field of laser cutting, and in particular relates to a split interactive bed of a laser cutting machine. Background Art

[0002] Laser cutting machine is a device that uses a high-energy-density laser beam to cut materials. The laser generator in the laser cutting machine generates a high-energy-density laser beam, which is focused on the surface of the material to be cut through optical systems such as optical fibers or reflectors. The energy of the laser causes the material to melt, vaporize or burn rapidly, while the auxiliary gas system sprays high-pressure gas to blow the melted or vaporized material away from the cutting area, thereby forming a slit and achieving the purpose of cutting the material.

[0003] The existing laser cutting machine bed usually adopts an integrated welded structure, which basically has the following defects: due to its large bed size, it may be restricted by roads, bridges and other transportation facilities during transportation; the integral bed usually requires a lot of welding work to ensure its structural stability, but the welding process is prone to problems such as stress concentration and deformation, which places very high requirements on the welding process; the structure is relatively fixed, when the laser cutting machine needs to be expanded or redesigned, the structure of the bed may not meet the new requirements, which requires the entire bed to be redesigned and manufactured, increasing costs and time costs.

[0028] After adopting the above technical solution, the present invention has the following beneficial effects compared with the prior art:

[0029] (1) The present invention realizes the assembly of the bed of the laser cutting machine by disposing a cross beam between the fixed longitudinal beam and the movable longitudinal beam, wherein the two ends of the cross beam are respectively connected with the first connecting part through a clamping part and a plug-in part, and are plug-connected with the second connecting part, thereby improving the overall installation efficiency.

DETAILED DESCRIPTION

[0046] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. The following embodiments are used to illustrate the present invention but are not used to limit the scope of the present invention.

[0047] In the description of the present invention, it should be noted that the directions or positional relationships indicated by terms such as “upper”, “lower”, “front”, “back”, “left”, “right”, “vertical”, “inside” and “outside” are based on the directions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore cannot be understood as a limitation on the present invention.

[0048] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0049] like Figures 1 to 9 As shown, a split interactive bed of a laser cutting machine described in the present invention comprises a fixed longitudinal beam 1 and a movable longitudinal beam 2, which are arranged parallel to each other, a first connecting portion 11 is arranged on the side wall of the fixed longitudinal beam 1 relative to the movable longitudinal beam 2, and a second connecting portion is arranged on the side wall of the movable longitudinal beam 2 relative to the fixed longitudinal beam 1;

[0050] A plurality of cross beams 4 are arranged between the fixed longitudinal beam 1 and the movable longitudinal beam 2. A clamping portion 36 is provided at one end of each cross beam 4 to form a clamping connection with the first connecting portion 11. A plug-in portion 3 is provided at the other end of each cross beam 4 to form a plug-in connection with the second connecting portion, so as to fix the fixed longitudinal beam 1, the movable longitudinal beam 2 and the plurality of cross beams 4.

[0051] According to the present invention, the interactive bed of the laser cutting machine includes longitudinal beams that are symmetrically and parallelly arranged on the left and right sides. One of the longitudinal beams is fixedly arranged on the ground at the site, and the other can be relatively movable, and the two are spliced ​​by the crossbeams 4 arranged at intervals along the length direction of the two longitudinal beams. Specifically, the first connecting part 11 and the second connecting part are respectively arranged on the opposite side walls of the fixed longitudinal beam 1 and the movable longitudinal beam 2, and the clamping part 36 and the plug-in part 3 are respectively arranged at both ends of the crossbeam 4. The movable longitudinal beam 2 and the crossbeam 4 can be quickly assembled on the fixed longitudinal beam 1 by clamping and fixing the clamping part 36 with the first connecting part 11 and plug-in fixing the plug-in part 3 with the second connecting part. By assembling the bed of the laser cutting machine by a disassembled combination method, after arriving at the site of use, the disassembled crossbeam 4 and the movable longitudinal beam 2 can more easily enter the installation position through narrow passages, doorways, etc., and then be assembled. Compared with the integral bed, it does not require large lifting equipment and complicated installation processes, which greatly improves the installation efficiency, shortens the equipment installation and commissioning cycle, and enables the laser cutting machine to be put into production more quickly.

[0052] Furthermore, the first connection portion 11 extends from the fixed longitudinal beam 1 toward the direction close to the movable longitudinal beam 2, and the upper and lower side walls of the first connection portion 11 are provided with connection grooves 41 recessed inwardly;

[0053] The clamping portion 36 is recessed inward from the end of the cross beam 4 to form a clamping groove. The upper and lower side walls of the clamping groove are provided with protrusions. The two protrusions extend toward the middle and are clamped with the connecting groove 41 .

[0054] In the present invention, the first connecting part 11 extends transversely on the side wall of the relatively movable longitudinal beam 2 and is in a block shape. The upper and lower side walls of the first connecting part 11 are concave to each other to form a connecting groove 41. One end of the crossbeam 4 is concave inward to form a clamping groove, and the concave depth of the clamping groove is consistent with the transverse extension length of the first connecting part 11, so that when the first connecting part 11 extends into the clamping groove, the side wall of the first connecting part 11 abuts against the groove bottom of the clamping groove. And the two sides of the clamping groove completely penetrate the front and rear side walls of the crossbeam 4, so that the clamping groove is hole-shaped. In addition, the upper and lower side walls of the clamping groove are raised upward to form a protrusion, wherein the size of the protrusion matches the connecting groove 41. In the specific assembly process, the transverse end with the connecting groove 41 is made to correspond to the first connecting part 11, and the front and rear sliding are matched, and the clamping is achieved by the matching of the protrusion and the connecting groove 41, thereby ensuring that one end of the crossbeam 4 is limitedly connected in the horizontal direction.

[0055] Furthermore, the second connecting portion at least includes a support member that can slide relative to the movable longitudinal beam 2, and a plug hole 34 is provided on the support member;

[0056] The plug-in portion 3 at least includes a plug-in block 12 that can reciprocate vertically, and the plug-in block 12 is matched with the plug-in hole 34 .

[0057] In the present invention, the support member on the second connecting part of the movable longitudinal beam 2 extends perpendicularly to the direction of the movable longitudinal beam 2, and the support member can move in a direction perpendicular to the movable longitudinal beam 2 in accordance with the movable longitudinal beam 2. A plug hole 34 is provided on the support member, and the position relative to the movable longitudinal beam 2 is changed by the movement of the support member. A plug part 3 is provided at the end of the cross beam 4 that is relatively far from the clamping part 36, and the moving direction of the plug block 12 on the plug part 3 is perpendicular to the support member and contacts the side wall of the support member. Specifically, a limit claw is provided on the support member, which is provided on the side away from the fixed longitudinal beam 1 and extends upward. In the process of the support member moving relative to the movable longitudinal beam 2, the limit claw can resist the movable longitudinal beam 2 and drive it to move toward the side close to the fixed longitudinal beam 1. The plug block 12 is constantly approaching the plug hole 34 until the plug block 12 is connected to the plug hole 34, so that the support member pushes the movable longitudinal beam 2 to move until it reaches the matching position (the fixed longitudinal beam 1 and the movable longitudinal beam 2 are parallel to each other).

[0058] Furthermore, the second connecting portion further comprises a support plate 31, the longitudinal section of which is U-shaped, and a slide rail is arranged on the side wall of the support plate 31, and both ends of the slide rail extend along a length direction perpendicular to the movable longitudinal beam 2;

[0059] The bottom of the support member is slidably connected to the slide rail, and the upper end of the support member is disposed against the bottom of the movable longitudinal beam 2 .

[0060] In the present invention, the movable longitudinal beam 2 is supported by a support plate 31, and the support plate 31 is U-shaped in the longitudinal section along the movable longitudinal beam 2. The bottom of each support plate 31 is fixed to the ground by bolts, and the preliminary positioning of the cross beam 4 is preliminarily completed. A slide rail is arranged on the U-shaped groove wall of the support plate 31 along the length direction of the movable longitudinal beam 2, and the support member is slidably connected on the slide rail so that the support member can move horizontally along the extension direction of the slide rail. Specifically, the top of the support member is arranged in contact with the bottom side wall of the movable longitudinal beam 2. A hydraulic cylinder is arranged on one side wall of the support plate 31, and the driving end of the hydraulic cylinder is connected to the side wall of the support member. By starting the hydraulic cylinder, the limiting claw of the support member is gradually abutted against the side wall of the movable longitudinal beam 2 and drives the movable longitudinal beam 2 to move to the side close to the fixed longitudinal beam 1. During the movement, the plug-in block 12 is plugged into the plug-in hole 34 on the support member, so that the movable longitudinal beam 2 is assembled to the specified position.

[0061] Furthermore, the support member comprises,

[0062] The slide plate 32 is slidably connected to the slide rail, and a first telescopic assembly 33 is provided between the slide plate 32 and the cross beam 4;

[0063] The movable plate 35 is vertically and parallelly arranged with the slide plate 32 , and a second telescopic assembly 7 is arranged between the movable plate 35 and the slide plate 32 .

[0064] In the present invention, a second telescopic assembly 7 is provided between the slide plate 32 and the movable plate 35, which can ensure that the movable plate 35 can abut against the bottom side wall of the movable longitudinal beam 2. The plug-in hole 34 is provided on the movable plate 35, thereby ensuring that the plug-in block 12 and the plug-in hole 34 can be stably plugged in, and avoiding the plug-in hole 34 being too far away from the plug-in block 12 and failing to meet the plug-in condition.

[0065] In addition, the arrangement of the first telescopic assembly 33 between the slide plate 32 and the cross beam 4, which is slidably connected to the slide rail, can enable the slide plate 32 to adjust the spacing relative to the fixed longitudinal beam 1. Specifically, the first telescopic assembly 33 and the second telescopic assembly 7 include a telescopic rod, a telescopic sleeve and a telescopic spring. The telescopic rod is slidably inserted in the telescopic sleeve, and a telescopic spring is sleeved on the outside of the two. On the one hand, it can further ensure that the sliding track of the slide plate 32 is more stable. On the other hand, the resilience of the telescopic spring can assist the resetting action of the first connecting part 11.

[0066] Furthermore, the plug-in portion 3 further includes a vertically arranged sliding rod, which penetrates the side wall of the crossbeam 4 and is slidably connected thereto;

[0067] The upper end of the sliding rod is connected to an identification block 13 , and a laser sensor 14 is arranged on one side of the crossbeam 4 , and its irradiation light is arranged perpendicular to the identification block 13 .

[0068] In the present invention, a through hole is provided on the side wall of the crossbeam 4, and the sliding rod extends through the hole to the upper end of the crossbeam 4. A shoulder is provided at the upper end of the sliding rod to prevent the sliding rod from falling directly through the hole. The plug-in block 12 is connected to the sliding rod, and can be downward by its own gravity, so that the plug-in block 12 is plugged and connected with the plug-in hole 34. Preferably, the upper end of the sliding rod has an identification block 13, and a laser sensor 14 is provided at the height of the identification block 13 at the initial moment, and the direction of its outgoing line is perpendicular to the identification block 13. After the crossbeam 4 is assembled to the above connection, the corresponding identification block 13 is detected at this height by the laser sensor 14. If the identification block 13 is not detected, it means that the entire crossbeam 4 and the movable longitudinal beam 2 are installed in place and the assembly is completed; if the laser sensor 14 can detect a certain identification block 13, it means that the crossbeam 4 and the movable longitudinal beam 2 at that location are not assembled in place, and the crossbeam 4 and the movable longitudinal beam 2 at the corresponding position are checked and repaired.

[0069] Furthermore, a third telescopic assembly 9 is provided between the sliding rod and the plug-in block 12 , and a slope is provided on one side of the plug-in block 12 close to the movable longitudinal beam 2 , which is inclined from bottom to top toward the side gradually close to the movable longitudinal beam 2 .

[0070] In the present invention, a third telescopic assembly 9 is connected to the lower end of the sliding rod, wherein the third telescopic assembly 9 has the same structural composition as the first telescopic assembly 33 or the second telescopic assembly 7. Specifically, the sliding rod is connected to the bottom of the telescopic sleeve, the plug-in block 12 is connected to the telescopic rod, and the two ends of the telescopic spring are respectively connected to the plug-in block 12 and the side wall of the crossbeam 4. Therefore, when the plug-in block 12 is aligned with the plug-in hole 34, the plug-in block 12 can move downward more stably and be plugged into the plug-in hole 34 through the rebound effect of the telescopic spring.

[0071] In addition, the specific structure of the plug-in block 12 is as follows: a slope is provided on the side wall close to the movable longitudinal beam 2, wherein the slope is inclined upward, so that the plug-in block 12 has a smaller contact area with the side wall of the movable plate 35, thereby reducing friction and enabling the movable plate 35 to move smoothly.

[0072] Furthermore, a baffle 15 is provided on one side of the cross beam 4 close to the movable longitudinal beam 2 , and the connection between the baffle 15 and the movable longitudinal beam 2 is in the same plane as the end surface of the fixed longitudinal beam 1 , and the baffle 15 is gradually inclined away from the fixed longitudinal beam 1 .

[0073] In the present invention, an inclined baffle 15 is further provided on the side wall of the cross beam 4, wherein the baffle 15 is connected from the front end side wall of the cross beam 4 and is inclined in a direction away from the fixed longitudinal beam 1, so that an enclosed area with an angle is formed between the cross beam 4 and the baffle 15. In the specific assembly process, when the movable longitudinal beam 2 is driven to approach the fixed longitudinal beam 1 by the movable plate 35, the end of the movable longitudinal beam 2 will gradually be flush with the end face of the fixed longitudinal beam 1, thereby ensuring that the assembly between the fixed longitudinal beam 1, the movable longitudinal beam 2 and the cross beam 4 in the entire laser cutting machine can achieve the required accuracy.

[0074] Furthermore, it also includes a positioning component 8, which at least includes:

[0075] A fixing plate 81 is arranged on the upper side wall of the cross beam 4;

[0076] A positioning rod 83 is connected to the fixing plate 81 through the fourth telescopic assembly 82, and the positioning rod 83 is arranged perpendicular to the side wall of the fixing plate 81;

[0077] A plurality of positioning holes are arranged at intervals on the fixed longitudinal beam 1 , and the positioning rods 83 are slidably connected to the positioning holes.

[0078] In the present invention, in order to ensure that the installation position of each cross beam 4 on the fixed longitudinal beam 1 is determined, positioning holes are opened at equal intervals on the fixed longitudinal beam 1. A fixing plate 81 is arranged on the upper side of the cross beam 4, wherein the fixing plate 81 is connected with a fourth telescopic assembly 82 arranged transversely. The precise positioning of the cross beam 4 and the fixed longitudinal beam 1 is achieved by plugging the positioning rod 83 into the positioning hole. Among them, the structural composition of the fourth telescopic assembly 82 is consistent with that of the above-mentioned telescopic assembly. After the first connecting portion 11 is connected to the clamping portion 36, the degree of freedom of the cross beam 4 relative to the fixed longitudinal beam 1 in the length direction can be limited by the positioning assembly 8.

[0079] The present invention also provides a laser cutting machine having a detachable interactive bed of any of the above-mentioned embodiments. The laser cutting machine has the above-mentioned detachable bed. In actual application, each component can be disassembled and installed anytime and anywhere, and when the function is expanded or the design is modified, the structure of the bed can be adjusted and replaced at any time, which is more practical.

[0080] Furthermore, the laser cutting machine is provided with a detachable sawtooth platen 5, and each sawtooth platen 5 is connected between the movable longitudinal beam 2 and the fixed longitudinal beam 1 through a connecting assembly. The connecting assembly includes a T-shaped plug block 51, and a connecting block 52 is provided on the opposite side walls of the movable longitudinal beam 2 and the fixed longitudinal beam 1. The connecting block 52 is provided with a T-shaped slot 53, and the T-shaped plug block 51 is inserted into the T-shaped slot 53, thereby ensuring that each sawtooth platen 5 can be quickly assembled or disassembled on the bed.

[0081] In addition, the laser cutting machine includes a cutting head 6 and a control system, which drives the cutting head 6 to move in three-dimensional space so that the cutting head 6 can accurately reach a designated position.

[0082] The above description is only a preferred embodiment of the present invention, and does not limit the present invention in any form. Although the present invention has been disclosed as a preferred embodiment as above, it is not used to limit the present invention. Any technician familiar with this patent can make some changes or modifications to equivalent embodiments of equivalent changes by using the technical content suggested above without departing from the scope of the technical solution of the present invention.
