Detailed implementation manners

[0016] In order to further elaborate on the technical means and effects adopted by the present invention to achieve the predetermined invention purpose, the following will, in conjunction with the accompanying drawings and preferred embodiments, describe in detail the specific implementation manners, structures, features and their effects of the present invention as follows.

[0017] As Figures 1-6 shown, a foldable cutting machine includes a cutting platform 1 and legs 2. The cutting platform 1 includes two end plates 11. The two end plates 11 are parallel and symmetrically arranged. Two cross beams 12 are installed in parallel between the two end plates 11. The two end plates 11 and the two cross beams 12 enclose a rectangular structure. Preferably, the cross beam 12 is an aluminum alloy profile, and a groove 121 is provided on the side surface of the cross beam 12. A plurality of support rods (not shown) are installed between the two cross beams 12, and a support table 13 is installed on the support rods. A cutting groove 131 is provided in the middle of the support table 13. The length of the support table 13 is less than the length of the cross beam 12, so that a hollow part is left between the support table 13 and the left end plate 11, and a sewage collection tray 14 is installed at the hollow part.

[0018] As Figure 3 , Figure 5As shown, a horizontal guide rail 3 is installed between two end plates 11 through a flipping bracket 31. The horizontal guide rail 3 is parallel to the length direction of the cutting platform 1. The cutting mechanism 4 is slidably installed at the lower end of the horizontal guide rail 3 through a sliding table. A transverse movement mechanism 32 is installed on the horizontal guide rail 3, and the transverse movement mechanism 32 drives the cutting mechanism 4 to reciprocate along the horizontal guide rail 3. Among them, the transverse movement mechanism 32 can be a gear-rack drive module, a synchronous belt and synchronous pulley drive module, a lead screw linear module, a rope drive module or a cylinder linear module, which is not limited here.

[0019] During use, the transverse movement mechanism 32 drives the cutting mechanism 4 to move along the horizontal guide rail 3 to realize the cutting operation of the workpiece. The coolant after cutting flows into the sewage collection tray 14 to gather and is recycled after treatment. In addition, the cutting angle can be adjusted by adjusting the angle of the flipping bracket 31. The structure and principle of the cutting machine are both prior arts and will not be elaborated here.

[0020] As Figures 1-6 shown, two mutually parallel guide plates 15 are respectively installed at both ends of the cross beam 12. The two guide plates 15 are vertically installed on the side surface of the cross beam 12, and the two guide plates 15 and the side wall of the cross beam 12 enclose a guide groove with an open outside. Among them, the guide plate 15 located on the outside is integrally formed with the end plate 11.

[0021] Four legs 2 are respectively slidably installed in the guide groove, so that the cutting platform 1 can reciprocate vertically along the legs 2. A cross bar 21 is installed between the two legs 2 at both ends of the long side of the cutting platform 1.

[0022] As Figure 2 shown, the upper end surface of the guide plate 15 is an inclined surface, and a plugging hole 151 is opened at the lower end of the inclined surface. The plugging hole 151 is located on the side of the guide plate 15 away from the cutting platform 1. The plugging hole 151 is an oblong hole, and the upper end of the plugging hole 151 is inclined towards the side of the cutting platform 1. The minimum distance between the plugging hole 151 and the cutting platform 1 is equal to the thickness of the leg 2. A clamping hole 152 is opened at the upper end of the inclined surface. The shape of the clamping hole 152 is the same as that of the plugging hole 151, and a clamping inlet 153 is opened at the lower end of the clamping hole 152.

[0023] As Figure 4 、 Figure 6 shown, the locking mechanism 5 includes a shaft pin 51. Two connecting rods 52 are fixedly arranged in parallel at both ends of the shaft pin 51. The connecting rods 52 are perpendicular to the shaft pin 51. A plug pin 53 is fixedly arranged at the end of the connecting rod 52 away from the shaft pin 51. The plug pin 53 is parallel to the pin shaft 51, and the two plug pins 53 are arranged facing each other. The shaft pin 51, the connecting rod 52 and the plug pin 53 enclose a semi-open rectangular structure.

[0024] The plug pin 53 is plugged in the plugging hole 151, and the plug pin 53 extends into the space between the two guide plates 15. The shaft pin 51 can be flipped around the plug pin 53 to be clamped into or pulled out of the clamping hole 152.

[0025] As shown Figure 1 , Figure 4 , Figure 5 In the figure, a first connection hole 23 is provided at the upper end of the outrigger 2. The first connection hole 23 coincides with the cutting platform 1 at the highest position. A first locking member 24 is detachably installed at the first connection hole 23. Among them, the first connection hole 23 is a threaded hole, and the first locking member 24 is a screw rod. The first locking member 24 passes through the first connection hole 23 and abuts against the cutting platform 1 to assist in fixing the cutting platform 1 during the working state and ensure the stability of the cutting platform 1.

[0026] As shown Figure 2 , Figure 3 , Figure 4 In the figure, when changing to the working state, first lift the cutting platform 1 so that the outrigger 2 is lower than the clamping hole 152, then insert the shaft pin 51 into the clamping hole 152 from the card entrance 153, and lower the cutting platform 1. The outrigger 2 rises relative to the cutting platform 1, pushing the shaft pin 51 to the upper end of the clamping hole 152. At this time, the shaft pin 51 realizes the vertical fixation of the outrigger 2. When the shaft pin 51 rises, the plug pin 53 synchronously moves up to the upper end of the insertion hole 151, and the plug pin 53 abuts against the side surface of the outrigger 2 to press the outrigger 2 from the side. Finally, insert the first locking member 24 into the first connection hole 23 to realize the auxiliary fixation of the cutting platform 1.

[0027] As shown Figure 3 , Figure 5 , Figure 6 In the figure, a second connection hole 25 is provided at the lower end of the outrigger 2. The second connection hole 25 coincides with the cutting platform 1 at the lowest position. A second locking member 26 is detachably installed at the second connection hole 25. Among them, the second connection hole 25 is a threaded hole, and the second locking member 26 is a screw rod. The second locking member 26 passes through the second connection hole 25 and abuts against the cutting platform 1 to assist in fixing the cutting platform 1 in the folded state and ensure the stability during transportation.

[0028] When folding, first lift the cutting platform 1 so that the outrigger 2 is lower than the clamping hole 152. Under the action of gravity, the shaft pin 51 moves down along the clamping hole 152 to the card entrance 153, and the plug pin 53 synchronously moves down along the insertion hole 151, separating the plug pin 53 from the outrigger 2 to facilitate the relative sliding of the cutting platform 1 and the outrigger 2. Then, flip the shaft pin 51 to remove it from the clamping hole 152, and lower the cutting platform 1 until the cutting platform 1 overlaps on the cross bar 21. Insert the second locking member 26 into the second connection hole 25 to realize the auxiliary fixation of the cutting platform 1. At this time, the cutting platform 1, the horizontal guide rail 3, and the cutting mechanism 4 are all located within the rectangular space surrounded by the four outriggers 2, and the cutting machine can be packaged by packing outside the outriggers 2.

[0029] Among them, the first connecting hole 23 and the second connecting hole 25 can also be through holes. In this case, both the first locking member 24 and the second locking member 26 are fixed pins. The first connecting hole 23 coincides with the groove 121 of the cutting platform 1 at the highest position, and the second connecting hole 25 coincides with the groove 121 of the cutting platform 1 at the lowest position. During use, the first locking member 24 (or the second locking member 26) is passed through the first connecting hole 23 (or the second connecting hole 25) and extended into the groove 121 to achieve auxiliary fixation.

[0030] As Figure 3 , Figure 5 shown, a handle 22 is installed at the cross bar 21 on the left side, and rollers 6 are installed on the right side surfaces of the two legs 2 on the right side. The lowest point of the roller 6 is tangent to the ground. At this time, by lifting the handle 22 from the left side to lift the legs 2 off the ground, the cutting machine can be carried through the rollers 6.

[0031] The technical solution provided by the embodiment of the present application has at least the following technical effects or advantages: 1. By slidably installing the cutting platform on the legs with cross bars, the folded cutting platform and the cutting mechanism can be accommodated in the rectangular space surrounded by the four legs, and the legs are used to protect the cutting machine, so that the long-distance transportation of the cutting machine can be satisfied without using an additional wooden box, saving transportation costs; 2. The locking and fixation between the legs and the cutting platform are realized through the flipable shaft pin, improving the convenience of folding the cutting machine; the working state of the cutting platform is assisted and fixed by the first locking member, ensuring the safety of using the cutting machine; 3. The folded cutting platform is fixed by the second locking member, which can improve the stability of the cutting machine and ensure the safety of the cutting machine during transportation; 4. By installing a handle and rollers on both sides of the cutting machine respectively, lifting the handle can make the rollers contact the ground, facilitating the transfer of the cutting machine within the work site.

Although the present invention has been disclosed above with the preferred embodiment, it is not intended to limit the present invention. Any person skilled in the art can make some changes or modifications to the equivalent embodiments by using the disclosed technical content within the scope of the technical solution of the present invention.
