Abstract
The invention relates to a drilling tool for the processing of an annular groove, which comprises a tool handle and a tool bit, wherein the tool bit is arranged at the lower end of the tool handle, a chip discharging groove is formed in the side wall of the tool bit, an outer tool blade is arranged on the edge of the chip discharging groove, a cutting groove is formed in the end part of the tool bit, an inner tool blade is arranged on the side wall of the cutting groove, the outer tool blade is used for processing the outer sidewall of the annular groove, the inner tool blade is used for processing the inner sidewall of the annular groove, the outer tool blade and the inner tool blade cut a workpiece in the rotation direction of the drilling tool, and chips generated in cutting is discharged through the chip discharging groove. Compared with the prior art, the drilling tool has the advantages of high processing precision, stable processing, low cost and the like.
Description
Technical field
The present invention relates to a kind of drill, especially relate to a kind of drill for processing annular groove.
Background technology
Step cutting pattern microwave pcb plate adopts lbg or the positive and negative milling of milling machine mostly at present, and the lbg used time compares
Grow and cost is larger, batch production is difficult to.The positive and negative milling of milling machine is time-consuming longer, and is subject to milling machine flatness, main shaft rotation essence
It is also difficult to realize volume production, quality also can be affected for the impact such as degree.
Content of the invention
The purpose of the present invention is exactly to overcome the defect of above-mentioned prior art presence to provide one kind to be used for processing annular
The drill of groove.
The purpose of the present invention can be achieved through the following technical solutions:
A kind of drill for processing annular groove, including handle of a knife and cutter head, described cutter head is located at handle of a knife lower end, described
The side wall of cutter head offer chip area, this chip removal groove edge is provided with outer blade, and the lower end of described cutter head offers cutting slot,
The side wall of this cutting slot is provided with interior blade, and described outer blade is used for processing the lateral wall of annular groove, and described interior blade is used
In the madial wall of processing annular groove, outer blade and interior blade, along the direction of rotation cutting workpiece of drill, cut the chip producing
Discharged by chip area.
Described cutting slot is u connected in star.
Described chip area is circular groove.
Described cutter head is the cutter head being provided with 30 °～70 ° of anglecs of rotation.
The length of described outer blade is 6～14mm, and the length of interior blade is 2～4mm.
Compared with prior art, the invention has the advantages that
1st, machining accuracy is high: very high using this kind of drill produced circular arc type step pcb plate impulse- free robustness, precision.
2nd, cost-effective: can to repeatedly use in use.Reduce Material Cost.
3rd, process and stablize: due to using hard alloy, material hardness and height.Controllability is produced using rig good.
4th, be widely used: can Machining Arc, annulus to pcb stepped plate, Rigid Flex all can make.
Brief description
Fig. 1 is the perspective view of the present invention；
Fig. 2 is the main structure diagram of the present invention；
In figure, 1, handle of a knife, 2, outer blade, 3, chip area, 4, cutting slot, 5, interior blade.
Specific embodiment
The present invention is described in detail with specific embodiment below in conjunction with the accompanying drawings.
Embodiment
As shown in figure 1, a kind of drill for processing annular groove, including handle of a knife 1 and the knife being provided with 65 ° of anglecs of rotation
Head, cutter head is located at the lower end of handle of a knife 1, and the side wall of cutter head offers chip area 3, and this chip area 3 is in circular arc, and its edge is provided with outer
Blade 2, the lower end of cutter head offers cutting slot 4, and this cutting slot 4 is in u shape, and its side wall is provided with interior blade 5, and outer blade 2 is used for adding
The lateral wall of work annular groove, interior blade 5 is used for processing the madial wall of annular groove, and outer blade 2 and interior blade 5 are along the rotation of drill
Turn direction cutting workpiece, get out the annular groove of different depth according to thickness of workpiece, and cut the chip of generation by chip area 3 row
Go out.
Cutter head is processed into particulate casting using hard alloy and forms, and has very high hardness and accuracy, can process difference
The pcb plate of material, can Continuous maching more than 3000 times, and counter can grind recycling.The length of whole drill is 38mm, blade
Length is 10mm, and the length of interior blade is 2mm, has good cutting power and chip removal ability.
