Description

Woodworking lockhole milling cutter

Technical Field

The utility model relates to a numerical control cutter technical field, concretely relates to carpenter's lockhole milling cutter.

Background

A milling cutter is a rotating tool with one or more cutter teeth for milling. When in work, each cutter tooth cuts off the allowance of the workpiece in sequence and intermittently. The milling cutter is mainly used for processing planes, steps, grooves, formed surfaces, cut-off workpieces and the like on a milling machine. The prior milling cutter has the problems that when the prior milling cutter is used for drilling, drilling and milling a wood door, the hole is not easy to drill, a cutter body is easy to break, chip removal is not smooth, and the wood is easy to explode.

SUMMERY OF THE UTILITY MODEL

The utility model discloses an it is not enough to overcome above-mentioned condition, aims at providing the technical scheme that can solve above-mentioned at least one kind of problem.

The utility model provides a carpenter's lockhole milling cutter, its includes the handle of a knife and establishes the cutter body in the handle of a knife upper end, the top of cutter body is equipped with a plurality of knife tips that are the spiral and arrange, the side shaping of cutter body has a plurality of cutting portions, and is a plurality of cutting portion is the spiral setting along the length direction of cutter body, cutting portion is including being the chip groove that is the spiral setting along cutter body length direction, the left side of chip groove is equipped with the cutting edge.

Preferably, the number of the knifepoints is three.

Preferably, three cutting parts are arranged, the cutting parts are respectively and correspondingly arranged between the adjacent tool tips, and the upper ends of the cutting blades in the cutting parts are connected to the tool tips corresponding to the cutting parts.

Preferably, a multi-section transverse groove is arranged between the right side of the chip groove and the cutting blade.

Preferably, the right side of the bottom of the cutter tip is provided with a groove arranged along the length direction of the cutter tip.

Preferably, the groove is inclined outward.

Compared with the prior art, the beneficial effects of the utility model are that: the utility model relates to a carpenter's lockhole milling cutter sets the radian and the chip groove of cutting blade to the spiral, can make the cutting more light, and the chip removal is quick more, clean, sets up the cross slot on the cutter body and can be convenient for press the piece of cutting absolutely, the discharge of being convenient for.

Additional aspects and advantages of the invention will be set forth in part in the description which follows and, in part, will be obvious from the description, or may be learned by practice of the invention.

Fig. 1 is a schematic structural diagram of the present invention.

In the figure: 1. a knife handle; 2. a cutter body; 3. a nose; 4. a cutting portion; 5. a chip groove; 6. a cutting blade; 7. A transverse groove; 8. and (4) a groove.

Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely below, and it should be understood that the described embodiments are only some embodiments of the present invention, but not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

Referring to fig. 1, in an embodiment of the present invention, a woodworking lockhole milling cutter includes a cutter handle 1 and a cutter body 2 disposed at an upper end of the cutter handle 1, a plurality of cutter points 3 arranged spirally are disposed at a top of the cutter body 2, a plurality of cutting portions 4 are formed at a side edge of the cutter body 2, the plurality of cutting portions 4 are spirally disposed along a length direction of the cutter body 2, each cutting portion includes a chip groove 5 spirally disposed along the length direction of the cutter body 2, and a cutting blade 6 is disposed at a left side of the chip groove 5; the cutting blade 6 and the chip removal groove 5 are arranged to be spiral, so that the cutting is easier, and the chip removal is quicker.

Further, three tool noses 3 are arranged.

Furthermore, three cutting parts 4 are arranged, the cutting parts 4 are respectively and correspondingly arranged between the adjacent tool noses 3, and the upper ends of the cutting blades 6 in the cutting parts 4 are connected to the tool noses 3 corresponding to the cutting blades; the cutting part 4 is arranged to be spiral, so that the cutting is easier and the chip removal is quicker.

Furthermore, be equipped with multistage cross slot 7 between the right side of chip groove 5 and cutting blade 6, set up cross slot 7 and can be convenient for press the piece of cutting absolutely, be convenient for discharge.

Furthermore, the right side of the bottom of the tool nose 3 is provided with a groove 8 arranged along the length direction of the tool nose 3, and the groove 8 is arranged to facilitate chip removal.

Further, the groove 8 is arranged obliquely outwards, and the oblique arrangement of the groove 8 is favorable for accelerating the removal of the cut chips.

It is obvious to a person skilled in the art that the invention is not restricted to details of the above-described exemplary embodiments, but that it can be implemented in other specific forms without departing from the spirit or essential characteristics of the invention.
