Abstract

This invention relates to a corner cutting machine, comprising: a machine base; a cutting mechanism including a first cutting unit, the first cutting unit including two first blades, the two first blades being oscillating relative to each other on the machine base; and at least one adjustment mechanism, the at least one adjustment mechanism being disposed on the machine base, the at least one adjustment mechanism being capable of driving one of the first blades to move relative to the other first blade to adjust the relative angle; thereby adjusting the angle between the first blades.

Claims

1. A corner-cutting machine, comprising: One machine; A cutting mechanism includes a first cutting unit, the first cutting unit including two first blades, the two first blades being oscillating relative to each other on the machine base; and at least one adjusting mechanism, the at least one adjusting mechanism being disposed on the machine base, the at least one adjusting mechanism being able to drive one of the first blades to move relative to the other first blade to adjust the relative angle.

2. The corner cutting machine as claimed in claim 1, wherein the two first cutter bodies oscillate relative to the machine table along the same first rotation axis.

3. The corner cutting machine as claimed in claim 2, wherein the machine base is provided with a first guide portion extending about the first rotation axis, each of the first blades includes a blade holder, a cutting blade and a second guide portion, the cutting blade and the second guide portion are respectively disposed on the blade holder, and the second guide portion is disposed on the first guide portion in cooperation with the first guide portion and is movable relative to the first guide portion along the extension path of the first guide portion.

4. The corner cutting machine as claimed in claim 3, wherein one of the first guide portion and the second guide portion is a guide groove and the other is a guide member that slides into the guide groove, the guide member being arc-shaped.

5. The corner cutting machine as claimed in claim 1, wherein each of the adjustment mechanisms includes a control member, a screw, and an adjustment member, the control member being connected to the screw and capable of driving the screw to rotate, the adjustment member being movably disposed on the screw relative to the screw, and the adjustment member being connected to one of the first cutter bodies.

6. The corner cutting machine as claimed in claim 1, comprising two adjustment mechanisms, the two adjustment mechanisms being respectively disposed on the machine base and capable of driving one of the first cutter bodies respectively.

7. The corner cutting machine according to any one of claims 1 to 6, further comprising a lifting base, the lifting base being movably disposed on the machine platform, the cutting mechanism further comprising a second cutting blade unit, the second cutting blade unit comprising two second blades, the two second blades being angularly adjustable relative to each other disposed on the lifting base, the lifting base being provided with a first guide portion, each of the second blades being provided with a second guide portion, the second guide portion being movably disposed relative to the first guide portion.

8. The corner-cutting machine as described in claim 7, further comprising at least one lifting drive unit, the first guide portion including a rotary slide rail and a guide groove, the guide groove being formed between the rotary slide rail and the lifting seat, the second guide portion including a locking block that can slide into the guide groove, each of the lifting drive units being disposed on the lifting seat and capable of driving the rotary slide rail to move up and down between a clamping position and a releasing position; wherein... When the rotary slide rail is in the clamping position, it can clamp the locking block, preventing the locking block from moving relative to the guide groove; when the rotary slide rail is in the releasing position, it can release the locking block, allowing the locking block to move relative to the guide groove.

9. The corner cutting machine as claimed in claim 7, wherein the cutting mechanism further includes two linkage mechanisms, each linkage mechanism connecting one of the first blades and a corresponding second blade, such that one of the first blades can be linked to one of the second blades.

10. The corner-cutting machine as claimed in claim 4, wherein each of the adjustment mechanisms includes a control member, a screw, and an adjustment member; the control member is connected to the screw and can drive the screw to rotate; the adjustment member is movably disposed on the screw relative to the screw; the adjustment member is connected to one of the first blades; the corner-cutting machine includes two adjustment mechanisms, which are respectively disposed on the machine base and can respectively drive one of the first blades; the corner-cutting machine further includes a lifting seat, which is movably disposed on the machine base; the cutting mechanism further includes a second cutting unit, which includes two second blades. Two second blades are angularly adjustable on the lifting base. The lifting base has a first guide portion, and each second blade has a second guide portion. The second guide portions are movably positioned on the first guide portions. The corner cutting machine further includes at least one lifting drive unit. The first guide portion includes a rotary slide rail and a guide groove, with the guide groove formed between the rotary slide rail and the lifting base. The second guide portion includes a locking block that can slide into the guide groove. Each lifting drive unit is located on the lifting base and can drive the rotary slide rail to move up and down between a clamping position and a releasing position. When the rotary slide rail is in the clamping position, it can clamp the locking block, preventing the locking block from moving relative to the guide groove. When the rotary slide rail is in the releasing position, it can release the locking block, allowing the locking block to move relative to the guide groove. The cutting mechanism further includes two linkage mechanisms, each linkage mechanism connecting one of the first blades and the other of the second blades, so that one of the first blades can be linked to one of the second blades. The corner cutting machine further includes a drive unit, which is located on the machine base and can drive the lifting seat to rise and fall. The two second blades can swing relative to the lifting seat along a second rotation axis as a rotation center. The rotary slide rail and the guide groove extend around the second rotation axis. The machine base is further provided with a plurality of guide posts, and the lifting seat is further provided with a plurality of guide holes, each guide hole fitting one of the guide posts and being able to move relative to one of the guide posts along the extension direction of the guide post.
