In addition, those skilled in the art may combine and combine the different embodiments or examples described in this specification and the features of the different embodiments or examples, without contradiction.

[0031] like Figures 1 to 8 As shown, a variable-boundary honeycomb panel positioning and cutting machine of the present invention comprises a machine frame 1 and a platform frame assembly installed on the top of the machine frame 1. In a preferred embodiment, a collecting hopper 8 is arranged at the bottom of the machine frame 1, and the honeycomb panels to be processed are laid on the top surface of the platform frame assembly. The honeycomb panels are edge cut and thickness milled by tool equipment, and waste materials can be directly discharged from the gap on the top surface of the platform frame assembly. The collecting hopper 8 is convenient for collecting waste materials.

[0032] Preferably, Figure 6 As shown, both side walls and the bottom surface of the collecting hopper 8 are sloped surfaces, and a discharge port 81 is provided at the low point of the bottom surface, and waste is discharged from the discharge port 81. The discharge port 81 is located on the back side of the collecting hopper 8, and an observation window 82 is provided on the front side of the collecting hopper 8. The bottom surface of the collecting hopper 8 is made into a sloped type, and the waste gathers toward the low point at the bottom of the collecting hopper 8, which is convenient for discharge.

[0033] The platform frame assembly includes supporting uprights 2 and movable uprights 3. The supporting uprights 2 are in the form of long plates, and the movable uprights 3 are in the form of short plates. The supporting uprights 2 are arranged in gaps and fixed on the machine frame 1 in at least three groups. In some embodiments, each supporting upright 2 is arranged longitudinally according to the processing shape, and adjacent supporting uprights 2 have gaps directly to facilitate the discharge of waste.

[0034] The top surface of the support plate 2 forms a support platform, which includes a positioning support portion 21 and a tool groove 22. After all the support plates 2 are arranged and installed, the tool grooves 22 correspond to each other. The tool grooves 22 can be a whole surface after corresponding to each other to meet the requirements of cutting any shape within the range of the support platform, and can also be set according to the limited tool trajectory to facilitate the tool trajectory of the cutting tool to give way and avoid interference between the support plate 2 and the tool and damage to the tool.

[0035] The movable vertical plate 3 is detachably mounted on the side of the supporting vertical plate 2 corresponding to the tool groove 22. When edge cutting is performed according to a certain tool path, the movable vertical plate 3 at the corresponding position of the tool groove 22 can be removed to make room for the tool. When the cutting shape is changed or thickness cutting is performed, the movable vertical plate 3 is installed on the supporting vertical plate 2 at the tool path or the entire surface is installed to form a support at the same height as the positioning support part 21, thereby avoiding deformation of the honeycomb sheet due to lack of support here.

[0036] In the embodiment, in order to realize the detachable installation of the movable vertical board 3, a connecting slot plate 24 is arranged on the side of the supporting vertical board 2 at the bottom of the tool feeding slot 22, and a limiting slot 241 is provided on the top surface of the connecting slot plate 24; at least one connecting slot 31 is provided on each movable vertical board 3, and the connecting slot 31 is a vertical long slot. The connecting slot 31 of the movable vertical board 3 is correspondingly installed on the connecting slot plate 24, and the movable vertical board 3 slides downward and is inserted into the limiting slot 241.

[0037] Further preferably, the connecting groove plate 24 is formed by cutting and bending the plate surface of the supporting upright plate 2 in one piece, which is convenient for processing. The connecting groove plate 24 is bent by 90 degrees, and the vertical connecting groove 31 of the movable upright plate 3 is inserted and connected thereto.

[0038] Further preferably, in order to achieve the positioning of the movable upright board 3, a positioning groove 25 is opened at a position corresponding to the corresponding tool feeding groove 22 on the side of the supporting upright board 2, and a positioning protrusion 32 is set on the movable upright board 3. After the movable upright board 3 is installed in place, the positioning protrusion 32 is installed corresponding to the positioning groove 25, thereby achieving accurate positioning of the movable upright board 3 on the side of the supporting upright board 2, ensuring that the connecting groove 31 of the movable upright board 3 is installed correspondingly on the connecting groove plate 24.

[0039] like Figure 1 and Figure 3 As shown, the top surface of the movable vertical plate 3 and the top surface of the positioning support part 21 are flush and evenly distributed with positioning protrusions 6. The positioning protrusions 6 are an integral structure with the movable vertical plate 3 and the supporting vertical plate 2. The positioning protrusions 6 on the top surface are used to penetrate and position the honeycomb holes of the honeycomb plate.

[0040] Preferably, Figure 3 and 8 As shown, the cross section of the positioning protrusion 6 is a symmetrical pentagon, with a piercing portion 61 at the top and a limiting portion 62 at the bottom. The piercing portion 61 is sharp at the top and wide at the bottom, and the limiting portion 62 is integrated with the piercing portion 61, wide at the top and narrow at the bottom. Thus, the side of the middle part of the positioning protrusion 6 as a whole forms a pointed tip, which facilitates the side of the positioning protrusion 6 to be fixed by acupuncture in the honeycomb hole.

[0041] Traditional triangular tooth tip Figure 7As shown, the product will be subjected to force along with the cutter head during cutting, and the product will deviate along the inclination direction of the tooth tip itself, which is not stable. Compared with the traditional triangular tooth tip, the positioning protrusion 6 used in the present invention has a concentrated force point on the side, no plane contact, no sliding, and better stability.

[0042] In some preferred embodiments, the platform frame assembly also includes an ejector plate 4 and an ejector drive mechanism 5. The ejector plate 4 is arranged on the side of the supporting plate 2 and is arranged parallel to the supporting plate 2. The ejector drive mechanism 5 is installed at both ends of the machine frame 1 and is connected to the ejector plate 4 through a transmission assembly 7. Initially, the top surface of the ejector plate 4 is arranged flush with the top surface of the supporting plate 2. When the honeycomb panel is processed and needs to be removed, the ejector drive mechanism 5 is actuated to lift the ejector plate 4 horizontally upward, and eject the honeycomb panel from the positioning protrusion 6, so as to facilitate the removal of the processed honeycomb panel.

[0043] In a specific embodiment, an ejection limit column 23 is provided on the side of the support vertical plate 2, and an oblique ejection limit groove 41 is provided on the ejection vertical plate 4. The ejection limit groove 41 is movably connected to the ejection limit column 23. Under the drive of the ejection drive mechanism 5, the ejection limit column 23 moves in the ejection limit groove 41 to realize an oblique ejection action.

[0044] Preferably, Figure 4 and Figure 5 As shown, the transmission assembly 7 includes a fork plate 71 and a connecting plate 72, the fork plate 71 is connected to the ejection drive mechanism 5, the bottom edge of the fork plate 71 is hinged on the machine frame 1, one end of the connecting plate 72 is mounted on the fork plate, and the other end is connected to the ejection vertical plate 4. Further preferably, the ejection drive mechanism 5 is a linear motor or a cylinder.

[0045] The ejection drive mechanism 5 can be installed obliquely, pushing the fork plate 71 to flip a certain angle along the hinge axis, driving the connecting plate 72 to push forward, and then driving the ejection vertical plate 4 connected to the connecting plate 72 to operate. With the cooperation of the ejection limit column 23 and the ejection limit groove 41, the forward thrust of the ejection vertical plate is converted into an ejection action obliquely upward along the ejection limit groove 41, thereby ejecting the honeycomb panel from the top surface of the supporting vertical plate 2.

[0046] The specific embodiments of the present invention are merely explanations of the present invention and are not limitations of the present invention. After reading this specification, those skilled in the art may make modifications to the embodiments without any creative contribution as needed. However, such modifications are protected by the patent law as long as they are within the scope of the claims of the present invention.
