[0036] The utility model is further described in detail below in conjunction with the accompanying drawings and embodiments.

[0037] The utility model embodiment discloses a modular bed of a cantilevered three-dimensional five-axis cutting machine.

[0038] Reference Figure 1A cantilever three-dimensional five-axis cutting machine modular bed includes a bed body 1, and the bed body 1 includes a plurality of bed units 2. The bed unit 2 has a plurality of different lengths. By freely combining the bed units 2 of different lengths, a plurality of bed bodies 1 of different lengths can be formed to meet different processing requirements. Before installing the laser cutting machine, the bed units 2 are first combined so that adjacent bed units 2 are connected and fixed to ensure that the laser cutting machine runs stably and smoothly.

[0039] Reference Figure 2 After the multiple bed units 2 are assembled, they are detachably connected through the connecting assembly 3. The connecting assembly 3 includes a tie rod 31, an inner tension rod 32, a clamping cylinder 33, a clamping nut 34 and a connecting plate 35. The tie rod 31, the inner tension rod 32, the clamping cylinder 33 and the clamping nut 34 are applied to the upper end of the bed body 1 to clamp and connect the upper ends of all the bed units 2, and the connecting plate 35 is applied to the lower end of the bed body 1 to connect the lower ends of all the bed units 2.

[0040] The tie rod 31 is in the shape of a screw, with an external thread on the outside, and an abutment portion 311 at one end. The tie rod 31 is hollow inside, and has a sliding groove 312 along the length direction. The sliding groove 312 runs through the inner and outer surfaces of the tie rod 31, and there are multiple sliding grooves 312 distributed circumferentially.

[0041] The bed unit 2 has mounting holes 21 formed through the side walls on both sides, and the tie rod 31 is installed through the mounting hole 21 of the bed unit 2 on one side. When the tie rod 31 is installed on the bed unit 2, the abutment portion 311 abuts against the side wall of the bed unit 2.

[0042] The inner tension rod 32 is a solid rod with a threaded section 321 at one end. The diameter of the threaded section 321 is equal to the diameter of the external thread of the tension rod 31. A compression piece 322 is installed on the outer circumference of the other end of the inner tension rod 32 to be retracted and extended by a spring.

[0043] The inner tension rod 32 is telescopically installed in the inner cavity of the tension rod 31, and the compression piece 322 is driven by the spring to extend out of the sliding groove 312. In this embodiment, the number of compression pieces 322 corresponds to the number of sliding grooves 312. When the inner tension rod 32 is telescopically installed relative to the tension rod 31, the compression piece 322 can slide in the sliding groove 312.

[0044] Furthermore, the clamping piece 322 has a guiding slope 323, and the guiding slope 323 faces the direction in which the inner tension rod 32 exits the bed unit 2. When the inner tension rod 32 needs to be taken out of the bed unit 2, the guiding slope 323 of the clamping piece 322 can move relative to the edge of the mounting hole 21, so that the clamping piece 322 retracts into the inner tension rod 32, and the inner tension rod 32 can be taken out of the mounting hole 21.

[0045] The clamping cylinder 33 is a hollow cylinder with two ends open, and has threads inside and outside. The clamping cylinder 33 is installed on the bed unit 2 on the other side and is sleeved on the outside of the tie rod 31 and the inner tension rod 32. The clamping cylinder 33 can be threadedly matched with the tie rod 31 and the inner tension rod 32.

[0046] When installing the clamping cylinder 33, the clamping cylinder 33 first cooperates with the threaded section 321 of the inner tension rod 32. By rotating the clamping cylinder 33, the inner tension rod 32 can be horizontally extended and retracted, so that the clamping piece 322 is pressed against the inner wall of the bed unit 2. When the clamping piece 322 abuts against the inner wall of the bed unit 2, the clamping cylinder 33 is continuously rotated, and the clamping cylinder 33 can be threadedly matched with the tension rod 31, and finally the clamping cylinder 33 is pressed against the inner wall of the bed unit 2 on the other side.

[0047] The clamping nut 34 is threadedly mounted on the outer wall of the clamping tube 33 and can be clamped against the side wall of the bed unit 2 on the other side.

[0048] The combination of the clamping cylinder 33 and the clamping plate 322 can press the inner walls of the bed units 2 on both sides against each other, and the combination of the abutment portion 311 and the clamping nut 34 can press the outer walls of the bed units 2 on both sides against each other, thereby making the connection of all the bed units 2 more stable.

[0049] Reference Figure 1 The connecting plate 35 is installed on the lower end side wall of the bed unit 2, and connects two adjacent bed units 2 by screw fixing.

[0050] Reference Figure 3 Furthermore, in order to reduce the weight of the bed unit 2, the bed unit 2 is hollow inside and has a material-reducing cavity 22. The bed unit 2 includes a bed shell 23 and a rib plate assembly 24 disposed in the material-reducing cavity 22. The rib plate assembly 24 is used to improve the structural strength of the bed unit 2. The rib plate assembly 24 divides the material-reducing cavity 22 into a plurality of cavity units.

[0051] The rib plate assembly 24 includes a horizontal rib plate 241 and a vertical rib plate 242. The horizontal rib plate 241 is horizontally arranged and welded to the bed unit 2, and the horizontal rib plate 241 enables the bed unit 2 to resist horizontal pressure. The vertical rib plate 242 is arranged perpendicular to the horizontal rib plate 241, and the vertical rib plate 242 is welded to the horizontal rib plate 241 and the bed unit 2, and the vertical rib plate 242 enables the bed unit 2 to resist vertical pressure.

[0052] In order to further reduce the weight of the bed unit 2 and facilitate welding operations, the horizontal rib plate 241 and the vertical rib plate 242 are both provided with through holes 243, which can connect all the cavity units, and the back of the bed shell 23 is also provided with a back plate notch 244, which penetrates the cavity unit. When the operator performs welding operations, he can penetrate from the back plate notch 244 and perform welding through the through holes 243.

[0053] Reference Figure 1 and Figure 3 Furthermore, the cross-section of the bed unit 2 is trapezoidal, and is a structure that is narrow at the top and wide at the bottom. The bed unit 2 includes a lower bed 25 and an upper bed 26 connected to the top of the lower bed 25. The thickness of the upper bed 26 is less than the thickness of the lower bed 25. Both the upper bed 26 and the lower bed 25 have guide rail surfaces 27, and the guide rail surfaces 27 are used for guide rail installation. After the guide rail is installed on the bed unit 2, the laser cutting machine can be installed on the guide rail. Due to the structure that is narrow at the top and wide at the bottom, the span of the guide rail surface 27 is increased, thereby improving the stability of the cantilever beam of the laser cutting machine and improving the overall stability of the bed unit 2.

[0054] Reference Figure 1 and Figure 4 Further, in order to facilitate the handling and lifting of the bed unit 2, a lifting assembly 4 is provided on the bed unit 2. The lifting assembly 4 includes an upper lifting lug 41 and a lower lifting lug 42, wherein the upper lifting lug 41 is provided on the side wall of the upper bed 26, and the lower lifting lug 42 is provided on the side wall of the lower bed 25.

[0055] By using the upper lifting lug 41, it is possible to facilitate vertical lifting of the bed unit 2. By using a combination of the upper lifting lug 41 and the lower lifting lug 42, it is possible to facilitate turning of the bed during processing.

[0056] 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.
