At present, a chinese patent net discloses a wood board cutting apparatus and a method for implementing the same [ application publication No.: CN110216740A, including a material conveying rack and a cutting device, the cutting device includes a frame, a mounting bottom plate is arranged at the bottom of the frame, a rotation angle driving servo motor is arranged on the mounting bottom plate, an output shaft of the rotation angle driving servo motor is connected with a rotary driving gear, a rotary mounting plate is also arranged on the top surface of the mounting bottom plate, teeth on the rotary mounting plate are meshed with the rotary driving gear, the rotary driving gear is driven by the rotation angle driving servo motor to rotate, the rotary driving gear drives the rotary mounting plate to rotate, the maximum rotation angle is 90 degrees, a saw rod lifting device and a saw blade cutting device are also arranged on the rotary mounting plate, the saw blade cutting device includes a saw blade, the saw rod lifting device is used for lifting and lowering a saw rod, the saw rod drives the saw blade to move up and down to cut a wood plate material, the cover plate is provided with a saw blade cutting hole at the corresponding position of the saw blade, the saw blade cutting hole corresponds to the cutting angle of the saw blade, and the saw blade cutting hole can be a strip-shaped hole with multiple angles or two symmetrically connected fan-shaped holes. When cutting timber, timber is placed on the apron, according to the angle needs of required cutting, for example cut 30 °, 60 ° or 90 °, under rotation angle drive servo motor's drive, rotary drive gear rotates, drives rotary mounting panel and rotates corresponding angle, and saw pole play pole device is used for the lift saw pole, and saw pole driving motor is for driving the saw pole to play the saw and provides power, and the saw pole drives the saw bit rebound, and the saw bit passes saw bit cutting hole and cuts the wooden plate material.

In order to cut cross sections with different angles on wood, the wood board cutting equipment adopts a complex rotating mechanism to drive a saw blade to rotate along the circumferential direction, so that the saw blade is aligned with different saw blade cutting holes in a cover plate as required, the saw blade cutting holes are strip-shaped holes, the width of each saw blade cutting hole is only slightly larger than the thickness of the saw blade, very high precision control is needed when the saw blade rotates, the rotating mechanism adopts a rotating angle to drive a servo motor to drive a rotating mounting plate to rotate through a gear transmission mechanism, the high precision control is difficult to achieve, and once the precision control is not good, the saw blade is abutted against the hole wall of the saw blade cutting hole or the lower surface of the cover plate in the process of ascending and cutting the wood, so that the saw blade is damaged.

Disclosure of Invention

The invention aims to provide a timber cutting machine aiming at the problems in the prior art, and the technical problems to be solved by the invention are as follows: how to solve the problem that the saw blade is easy to damage.

The purpose of the invention can be realized by the following technical scheme:

the utility model provides a timber cutting machine, includes cutting mechanism, cutting mechanism includes frame one, cutting platen and has the cutting aircraft nose of saw bit, the saw bit cutting hole has been seted up on the cutting platen, its characterized in that, cutting mechanism still includes can circumferential direction's rotating base and fixes the mounting bracket on rotating base, the cutting platen is fixed on the mounting bracket, be provided with the drive cutting aircraft nose on the mounting bracket and go up and down and can make the part of saw bit extend to the downthehole driving piece one of saw bit cutting for the cutting platen.

When the wood cutting machine works, wood is placed on the cutting table plate, the driving piece I drives the cutting machine head to move so that the saw blade is gradually close to the wood and cuts the wood, when the saw blade cuts the wood, part of the saw blade is located in the saw blade cutting hole, when the cutting angle needs to be adjusted, the rotating base rotates to drive the mounting frame to rotate, the mounting frame drives the cutting table plate and the cutting machine head to rotate together after rotating, namely, the saw blade and the saw blade cutting hole are always kept in a corresponding state, the relative positions of the saw blade and the saw blade cutting hole are unchanged, and the saw blade cutting hole are always in an aligned state in the wood cutting process, so that the problem that the saw blade and the saw blade cutting hole are difficult to align in the prior art is solved, the saw blade and the cutting table plate are prevented from; secondly, this structure is through adjusting the angle of saw bit and saw bit cutting hole simultaneously and cutting out the cross-section of different angles with timber, therefore only need set up a saw bit cutting hole on the cutting platen can, compare with prior art and reduced the setting number of saw bit cutting hole on the cutting platen, make things convenient for the manufacturing of cutting platen.

In one of the timber cutting machines described above, the cutting head is located above the cutting platen. Through the arrangement of the structure, the saw blade is positioned above the cutting hole of the saw blade due to the design that the cutting machine head is positioned above the cutting table plate, when the wood is cut, the saw blade moves downwards relative to the cutting table plate, the wood is placed on the cutting table plate, the saw blade is firstly contacted with the wood and cuts the wood, and when the wood is completely cut off, the saw blade moves downwards slightly for a very small stroke, so that the lower end part of the saw blade extends into the cutting hole of the saw blade, and the wood is completely cut off; and prior art's saw bit is located the below of saw bit cutting hole, and during the cutting timber, the saw bit will extend in the saw bit cutting hole earlier, makes the summit of saw bit upwards stretch out saw bit cutting hole again, and the saw bit contacts cutting timber with timber, because timber has certain thickness, and the saw bit will continue to go upward a section distance and just can cut off timber completely, and timber is cut off completely the in-process, and the stroke of saw bit rebound is longer.
