Abstract
Description
Technical Field
[0001] The utility model relates to a bed structure, more specifically, it relates to an extendable integral bed structure. Background Art
[0002] The length of common integral bed is mostly affected by the processing width of the processing machine tool. The longer the bed length, the more difficult it is to guarantee the front and rear accuracy of the integral bed. Therefore, it is more common in rough processing laser cutting operations with low precision requirements. However, rough processing operations are mostly used for rapid processing of large workpieces. The laser cutting head has a long back and forth distance, the bed is continuously impacted, and the joints are prone to breakage. Most of the splicing components in the prior art adopt an integrated structure connected to the bed. After damage, the entire bed can only be replaced, which is not only time-consuming and labor-intensive, but also very costly. Therefore, there is a need for an extendable integral bed structure that can replace splicing components individually.
[0003] In view of the above reasons, how to replace the splicing components individually is exactly the problem considered in this application. Utility Model Content
[0004] In view of the shortcomings of the prior art, an extendable integral bed structure is provided, and the device can replace the splicing components separately.
[0005] To achieve the above-mentioned purpose, the following technical solutions are provided: an extendable integral bed structure, comprising a bed, the bed being connected with a guide rail assembly and a splicing assembly, the guide rail assembly being connected with a mobile platform for mounting a laser cutting head, the splicing assembly comprising a connecting shell, the connecting shell being threadedly connected with a first screw threadedly connected with the bed, and the connecting shell being slidably connected with a first connecting member;
[0006] When in use, the connecting shells on the two bed frames are symmetrically arranged and connected to the same first connecting piece.
[0007] In summary, the above technical solution has the following beneficial effects: since the integrated splicing structure connecting the bed is easily damaged at the connection, which may lead to the need to replace the entire bed, the splicing structure is separately set as a detachable component, so that even if the connection is damaged, the integrity of the integral bed structure can be guaranteed, and only the splicing component needs to be replaced in time;
[0008] When in use, the connection shells on the two bed frames need to be aligned and symmetrically arranged, and the two ends of the same first connecting member are respectively inserted into the two connection shells, so that when the bed frame moves in a non-set direction, the first connecting member will contact the inner wall of the connection shell, thereby preventing the bed frame from moving. The left and right sides of the bed frame will not need to worry about movement because other structures, such as motors, are installed;
[0009] The connection strength between the connecting shell and the bed body depends on the strength of the first screw used for connection. Compared with the method of welding the connecting shell to the bed body, the first screw itself is a replaceable object, and when the two bed bodies move relative to each other, the stress will impact on the first screw, and its blocking effect is similar to welding and other methods. Therefore, if damage occurs, the first thing to be damaged is the first screw, followed by the connecting shell. The components of these splicing components are replaceable parts with simple structures. Therefore, when damage occurs, the splicing components can be replaced separately, and there is no need to replace the entire bed body. BRIEF DESCRIPTION OF THE DRAWINGS

[0020] The present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. The same parts are represented by the same reference numerals. It should be noted that the words "front", "rear", "left", "right", "upper" and "lower" used in the following description refer to directions in the accompanying drawings, and the words "bottom surface" and "top surface", "inside" and "outside" refer to directions toward or away from the geometric center of a specific component, respectively.
[0021] Reference Figure 1-5As shown, an extendable integral bed structure includes a bed 1, the bed 1 is connected to a guide rail assembly 2 and a splicing assembly 3, the guide rail assembly 2 is connected to a moving platform 4 for mounting a laser cutting head, the splicing assembly 3 includes a connecting shell 31, the connecting shell 31 is threadedly connected to a first screw 32 threadedly connected to the bed 1, and the connecting shell 31 is slidably connected to a first connecting member 33;
[0022] When in use, the connection shells 31 on the two bed bodies 1 are symmetrically arranged and connected to the same first connection member 33;
[0023] Since the integrated splicing structure connecting the bed 1 is easily damaged at the connection, which may lead to the need to replace the entire bed 1, the splicing structure is separately set as a detachable component, so that even if the connection is damaged, the integrity of the structure of the integral bed 1 can be guaranteed, and only the splicing component 3 needs to be replaced in time;
[0024] When in use, the connection shells 31 on the two bed frames 1 need to be aligned and symmetrically arranged, and the two ends of the same first connection member 33 are respectively inserted into the two connection shells 31, so that when the bed frame 1 moves in a non-set direction, the first connection member 33 will contact the inner wall of the connection shell 31, thereby preventing the bed frame 1 from moving. The left and right sides of the bed frame 1 will not move because other structures, such as motors, are installed;
[0025] The connection strength between the connecting shell 31 and the bed 1 depends on the strength of the first screw 32 used for connection. Compared with the method of welding the connecting shell 31 to the bed 1, the first screw 32 itself is a replaceable object, and when the two bed frames 1 move relative to each other, the stress will impact on the first screw 32, and its blocking effect is similar to that of welding and other methods. Therefore, if damage occurs, the first thing to be damaged is the first screw 32, followed by the connecting shell 31. The components of these splicing components 3 are replaceable parts with simple structures. Therefore, when damage occurs, the splicing components 3 can be replaced separately, and there is no need to replace the entire bed 1.
[0026] Furthermore, the guide rail assembly 2 includes a plurality of toothed guide rails 21, and a first connecting hole 22 is provided on the toothed guide rails 21;
[0027] When multiple bed frames 1 are spliced together, multiple toothed guide rails 21 are spliced together in sequence and the splicing locations are offset from the splicing locations of the bed frames 1;
[0028] The guide rail assembly 2 also includes a plurality of first guide rails 23 for guiding the movement of the mobile platform 4, and a second connecting hole 24 is provided on the first guide rails 23;
[0029] When multiple bed frames 1 are spliced, multiple first guide rails 23 are spliced in sequence and the splicing locations are offset from the splicing locations of the bed frames 1 , and the splicing locations of the multiple first guide rails 23 are also offset from the splicing locations of the multiple toothed guide rails 21 ;
[0030] The guide rail assembly 2 also includes a plurality of second guide rails 25 for guiding the movement of the mobile platform 4. The first guide rail 23 and the second guide rail 25 are respectively arranged on two mutually perpendicular planes of the bed 1. The second guide rail 25 is provided with a third connecting hole 26.
[0031] When multiple bed frames 1 are spliced, multiple second guide rails 25 are spliced in sequence and the splicing locations are misaligned with the splicing locations of the bed frames 1. The splicing locations of the multiple second guide rails 25 are also misaligned with the splicing locations of the multiple toothed guide rails 21. The splicing locations of the multiple second guide rails 25 are also misaligned with the splicing locations of the multiple first guide rails 23.
[0032] The first guide rail 23 and the second guide rail 25 are respectively arranged on two mutually perpendicular planes of the bed 1, so as to ensure the stability of the mobile platform 4 when moving;
[0033] By staggering the joints of the toothed guide rail 21, the first guide rail 23 and the second guide rail 25, the strength of the bed 1 at the joints can be increased to prevent the movement of the mobile platform 4 from being obstructed due to position differences among the joints of the toothed guide rail 21, the first guide rail 23 and the second guide rail 25 when the bed 1 moves slightly due to an impact.
[0034] Furthermore, a positioning hole 331 is provided on the first connecting member 33, and the connecting shell 31 is also detachably connected to a connecting cover 311, and the connecting cover 311 is fixedly connected to a positioning column 312 for inserting into the positioning hole 331;
[0035] When connecting two bed frames 1, after removing the connecting cover 311, move the first connecting member 33 to adjust the positioning hole 331 to a predetermined position, and finally close the connecting cover 311 again and insert the positioning column 312 on the connecting cover 311 into the positioning hole 331. By positioning and resisting the inner wall of the positioning hole 331, the two bed frames 1 can be effectively prevented from having a large relative movement.
[0036] Furthermore, both ends of the first connecting member 33 are fixedly connected with auxiliary members 332 protruding toward the direction away from the first connecting member 33. The surface of the auxiliary member 332 is arc-shaped, which can increase the force-bearing area in all directions. At the same time, the arc shape can reduce the problem of corner jamming when the first connecting member 33 is inserted into the connecting shell 31. When the bed 1 moves upward, the auxiliary member 332 can resist the connecting shell 31, thereby preventing the bed 1 from continuing to move.
[0037] Furthermore, the first connecting member 33 is also fixed with a second connecting member 34 having a trapezoidal cross-section, and the side surface of the second connecting member 34 and the auxiliary member 332 form a recessed shape, so that a part of the connecting cover 311 can be clamped by the side surface of the second connecting member 34 and the auxiliary member 332, thereby further strengthening the connection strength between the first connecting member 33, the second connecting member 34 and the connecting shell 31.
[0038] Furthermore, the connecting cover 311 is also threadedly connected to a second screw 313 threadedly connected to the connecting shell 31, and the moving direction of the first screw 32 and the moving direction of the second screw 313 are staggered, so that the installation positions of the first screw 32 and the second screw 313 can be independent of each other, preventing the occurrence of a screw breaking or stripping, which makes it impossible to remove other screws.
[0039] Furthermore, the bed 1 is connected with a plurality of groups of splicing components 3 arranged on different surfaces, which can further enhance the stability of the connection.
[0040] Furthermore, the connecting shell 31 can also be detachably connected to a protective shell 35 for blocking the side of the connecting shell 31. Due to the harsh environment of the assembly line, in order to prevent debris from entering the connecting shell 31 and causing the first connecting member 33 and the second connecting member 34 to be unable to be inserted into the connecting shell 31, a protective cover is provided to block the side of the connecting shell 31.
[0041] The above is only a preferred embodiment of the present invention. The protection scope of the present invention is not limited to the above embodiments. All technical solutions under the concept of the present invention belong to the protection scope of the present invention. It should be pointed out that for ordinary technicians in this technical field, some improvements and modifications without departing from the principle of the present invention should also be regarded as the protection scope of the present invention.
