In one embodiment, the plurality of first beds 110 are disposed at intervals along the length direction of the first beds 110, and the plurality of second beds 210 are disposed at intervals along the length direction of the second beds 210. The first connecting components 300 are provided with a plurality of first connecting components 300, and the first connecting components 300 are respectively arranged at the connecting positions of the adjacent first bed bodies 110 and the connecting positions of the adjacent second bed bodies 210 and used for respectively connecting the plurality of first bed bodies 110 and the plurality of second bed bodies 210, and the first adjusting components can also change the distance between the adjacent first bed bodies 110 and the distance between the adjacent second bed bodies 210 so as to adjust the position relation of the assembly surfaces on the adjacent first bed bodies 110 and the position relation of the assembly surfaces on the second bed bodies 210. The connecting plate 400 is disposed between the first lathe bed 100 and the second lathe bed 200, at least one end of the connecting plate 400 is provided with a gap with the first lathe bed 100 or the second lathe bed 200, and the second connecting assembly 500 can change the gap between the connecting plate 400 and the first lathe bed 100 or the second lathe bed 200.
In the machine tool 10 described above, the first bed 100 is formed by splicing the plurality of first beds 110, and the second bed 200 is formed by splicing the plurality of second beds 210, so that the size of the machine tool 10 is increased to be able to carry a larger-sized plate. The spliced machine tool 10 can ensure the parallelism of the first machine tool body 100 and the second machine tool body 200 through the first adjusting component, ensure the butt joint precision between the plurality of first machine tool bodies 110 and the butt joint precision between the plurality of second machine tool bodies 210 through the second adjusting component, avoid influencing the precision of large-size plates borne on the machine tool 10, and ensure the processing quality of the large-size plates in laser cutting.
Referring to fig. 2, in one embodiment, the first connecting assembly 300 includes first connecting members 310, the first bed body 110 and the second bed body 210 are respectively provided with first connecting members 310, two ends of the first bed body 110 are respectively provided with first connecting holes (not shown) which are matched with corresponding first connecting holes on the adjacent first bed bodies 110, so that the adjacent first bed bodies 110 are connected, a tool is used to rotate the first connecting members 310 to change the gap between the adjacent first bed bodies 110, a standard distance value is preset between the adjacent first bed bodies 110, the gap between the adjacent first bed bodies 110 is adjusted to a standard value through the first connecting members 310, and the synchronicity of the mounting hole intervals of the guide rails on the mounting surfaces of the adjacent first bed bodies 110 is ensured, so that the assembly accuracy is improved.

It should be noted that, the bottoms of the first bed 110 and the second bed 210 are respectively provided with a foot (not shown), and adjusting the foot can ensure that the adjacent first bed 110 and the adjacent second bed 210 are at the same height.
Further, since the mass of the first bed 110 or the second bed 210 is large, it is inconvenient to rotate the first connector 310 in adjustment. For easy adjustment, the first connector assembly 300 further includes a first abutment 320 spaced apart from the first connector 310. The first supporting member 320 is installed on each of the first bed body 110 and the second bed body 210, the right side of the first bed body 110 is further provided with a second connecting hole (not shown), the second connecting hole and the first connecting hole are arranged at intervals in the vertical direction, and it can be understood that when two first bed bodies 110 are connected, the first supporting member 320 will abut against the adjacent first bed bodies 110 after penetrating through the connecting holes on the right side of the first bed bodies 110, specifically, after penetrating through the end parts of the first bed bodies 110, the first supporting member 320 abuts against the end surfaces of the first bed bodies 110 which are oppositely arranged. Thus, when the distance between the adjacent first beds 110 is greater than the standard value, the first connecting member 310 pulls the adjacent first beds 110, and when the distance between the adjacent first beds 110 is less than the standard value, the first supporting member 320 is rotated to push out the first bed 100 on one side, thereby ensuring that the distance between the adjacent first beds 110 is equal to the standard value.
Further, a first operation opening 330 for operating the first connecting assembly 300 is formed on the side wall of the first bed body 110, and an operator can adjust the first connecting member 310 and the first supporting member 320 through the first operation opening 330. The first connectors 310 are disposed at intervals on the first bed 110, and the first supporting members are also disposed at intervals between the two first connectors 310. The adjustment of the first connector 310 mounted on the second bed 210 is the same and will not be described again.
Referring to fig. 3, in one embodiment, the second connection assembly 500 includes a second connection 510, and the second connection 510 is intended to mate with an adjacent first bed 110, connection plate 400 to connect the first bed 110, connection plate 400. In some embodiments, the connection plate 400 has only one end provided with the second connection member 510, and in other embodiments, both ends of the connection plate 400 are provided with the second connection member 510. In this embodiment, the second connecting members 510 are installed at both ends of the connecting plate 400, and the second connecting members 510 penetrate through one end of the connecting plate 400 and the side wall of the first bed 110, so as to be connected with the first bed 110. The second connecting member 510 penetrates through the other end of the connecting plate 400 and the sidewall of the second bed body 210 to be connected with the second bed body 210, and the gap between the first bed body 110 and the first connecting plate 400 and the gap between the second bed body 210 and the first connecting plate 400 can be changed by rotating the second connecting member 510 by using a tool, so that the gap between the first bed body 110 and the second bed body 210 is changed. A standard distance value is preset between the first bed 110 and the second bed 210, and after the gap between the first bed 110 and the second bed 210 is adjusted to a standard value through the second connection assembly 500, the levelness between the first bed 110 and the second bed 210 can be ensured.
Further, since the mass of the first bed 110, the second bed 210, and the connection plate 400 is large, it is inconvenient to rotate the second connection member 510. For easy adjustment, the second connection assembly 500 further includes a second abutment 520 spaced apart from the second connection member 510. The second supporting members 520 are installed at both ends of the connection plate 400, and the second supporting members 520 are abutted against the side walls of the second bed body 110 after penetrating the connection plate 400 from the connection plate 400 along the direction close to the second bed body 110, so that when the distance between the first bed body 110 and the second bed body 210 is greater than a standard value, the second adjusting members are rotated to pull the adjacent first bed body 110, and when the distance between the first bed body 110 and the second bed body 210 is smaller than the standard value, the second supporting members 520 are rotated to support the first bed body 110 so as to push the connection plate 400 away from the first bed body 110, and the distance between the first bed body 110 and the second bed body 210 is guaranteed to be equal to the standard value. The other end of the connection plate 400 is identical to the adjustment of the second bed body 210, and the second connection assemblies 500 are disposed at both ends of the connection plate 400, so that the adjustment range can be enlarged and the applicability can be improved. Further, referring to fig. 1, a second operation opening 530 for operating the second connection assembly 500 is further formed on the side wall of the first bed body 110, and an operator can adjust the second connection member 510 and the second supporting member 520 through the second operation opening 530. After the distance between the first lathe bed 100 and the second lathe bed 200 is adjusted to the standard value, a mating pad may be prepared and placed between the first lathe bed 100 and the connecting plate 400, between the second lathe bed 200 and the connecting plate 400, where the volume of the mating pad is equal to the volume between the first lathe bed 100 and the connecting plate 400 or between the second lathe bed 200 and the connecting plate 400, so that the contact area between the first lathe bed 100 and the connecting plate 400 or between the second lathe bed 200 and the connecting plate 400 can be increased, and the stability of connection is improved.
Referring to fig. 4, in an embodiment, the first bed 100 further extends with a first mount 340 along a direction approaching the second bed 200. A second mount (not shown) also extends on the second bed 200 in a direction approaching the first bed 100. The machine tool 10 further comprises a base 350 for carrying the plate, the first mounting seat 340 and the second mounting seat are both provided with the base 350, the base 350 arranged on the first mounting seat 340 is arranged at intervals with the side wall of the first machine body 100, and the base 350 arranged on the second mounting seat is arranged at intervals with the side wall of the second machine body 200. Because the mass of the plate material with larger size is larger, the base 350 is arranged at intervals with the side walls of the first lathe bed 100 and the second lathe bed 200, so that the side walls of the first lathe bed 100 and the second lathe bed 200 can be prevented from being inclined due to bearing larger gravity.
Referring to FIG. 5, in one embodiment, machine tool 10 further includes a reference bar 360, reference bar 360 being used to locate when the guide rail is installed. The reference bar 360 is detachably connected to the first lathe bed 100 and the second lathe bed 200, respectively, and extends along the length direction of the first lathe bed 100. Before the reference bar 360 is installed, the levelness of the reference bar 360 needs to be ensured by a tool such as a micrometer, and then the reference bar is installed on the first lathe bed 100 or the second lathe bed 200 and fixedly connected by a fastener, and the fastener can be selected from a connecting pad 370, a mating pad 380, and the like. When the guide rail is attached to the first bed 100 or the second bed 200, the parallelism between the guide rail and the first bed 100 or the second bed 200 can be ensured with reference to the reference bar 360.
Referring to FIG. 6, in conjunction with FIG. 1, in one embodiment, machine tool 10 also includes a drive mechanism 600. The drive mechanism 600 includes a drive member 610, a drive shaft 620, a first sprocket assembly 630, and a second sprocket assembly 640. The driving member 610 is mounted on the first bed 100 or the second bed 200, the first sprocket assembly 630 is mounted on the first bed 100, and the second sprocket assembly 640 is mounted on the second bed 200.

Specifically, the first sprocket assembly 630 includes gears 631 and chains 632, and the gears 631 are disposed at both ends of the reference bar 360 in the length direction. The chain 632 is disposed around the base 350 and is simultaneously mounted on the gear 631, the gear 631 is in driving connection with the transmission shaft 620 to provide driving force for the chain 632, the structure of the second sprocket assembly 640 is identical to that of the first sprocket assembly 630, which will not be described herein, and the plate is simultaneously supported by the chain 632 when being placed on the base 350, the chain 632 moves to drive the plate to move, and cooperates with a hydraulic lifting mechanism at the bottom of the plate, which can adopt the existing structure to realize the exchange of the plate.
