Abstract
The invention relates to a drilling cutter automatic in chip removal. The drilling cutter comprises a handle and a cutting part; a cutter point is arranged at the tail end of the cutting part; spiral cutting edges are arranged on the cutting part; a spiral chip removal groove is formed between the adjacent spiral cutting edges; a chip removal cavity is arranged inside the drilling cutter in the axial direction; a chip removal hole communicated with the chip removal cavity is formed in the chip removal groove; chip outlets communicated with the tail end of the chip removal groove are formed in the sidewalls of the handle; a chip storage unit is arranged in a circle in the circumferential direction on the handle where the chip outlets are formed; a chip absorption unit is arranged in the chip storage device. According to the drilling cutter automatic in chip removal, chips that cannot be discharged timely in the hole machining process can be absorbed into the chip storage unit by use of the chip absorption unit, and therefore, hole blockage is avoided, the hole machining accuracy is improved and the service life of the cutter is prolonged.
Description
Technical field
The present invention relates to cutting element field, be specifically related to a kind of can the bore cutter of automatic chip-removal.
Background technology
The most general in machining is exactly the processing in hole, and in hole machined process, chip enters in processed hole with cutter or remains in the chip area of cutter, easily cause hole plug, improve hole machined difficulty, reduce hole machined precision, shorten cutting-tool's used life, increase production cost.
Summary of the invention
For the problems referred to above, the object of this invention is to provide a kind of can the bore cutter of automatic chip-removal.
Realize technical scheme of the present invention as follows:
A kind of can the bore cutter of automatic chip-removal, comprise shank and blade, the end of described blade is provided with point of a knife, blade is provided with helical edges, is provided with helical flute between adjoining spiral sword, and described bore cutter inside is provided with the chip removal chamber axially arranged, described chip area has the chip-removal hole communicated with chip removal chamber, the sidewall of described shank has the discharging opening be communicated with chip area end, described discharging opening place shank circumference one circle is provided with storage bits device, is provided with bits-suction device in described storage bits device.
Further, described storage bits device is connected with shank threads.
Further, described storage bits device adopts transparent material.
Have employed above-mentioned scheme, in hole machined process, the cutting that cannot discharge in time, sucks cutting in storage bits device by bits-suction device, avoids hole plug, improve hole machined precision, improve cutter life.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention;
In figure, 1 is blade, and 11 is helical flute, and 12 is chip-removal hole, and 2 is shank, and 3 is chip removal chamber, and 31 is discharging opening, and 4 is storage bits device, and 41 is bits-suction device.
Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the invention will be further described.
As Fig. 1, a kind of can the bore cutter of automatic chip-removal, comprise shank 2 and blade 1, the end of described blade is provided with point of a knife, blade is provided with helical edges, helical flute 11 is provided with between adjoining spiral sword, described bore cutter inside is provided with the chip removal chamber 3 axially arranged, described chip area has the chip-removal hole 12 communicated with chip removal chamber, the sidewall of described shank has the discharging opening 31 be communicated with chip area end, described discharging opening place shank circumference one circle is provided with storage bits device 4, is provided with bits-suction device 41 in described storage bits device.Blade cuts a large amount of cuttings produced and directly gets rid of from chip area, the cutting that cannot get rid of in time sucks in storage bits device by bits-suction device, to avoid in hole residual cutting and cause hole plug so causing hole machining accuracy low, the setting of storage bits device and bits-suction device substantially increases hole machined precision, improve cutting-tool's used life, reduce production cost.
For the cutting making storage consider to be worth doing in device can be discharged smoothly, storage bits device is connected with shank threads, cutting in storage bits device is when gathering much the same amount, storage considered to be worth doing device and pulls down and carry out clearing up, and hole to chip removal chamber carry out detritus cleaning by air blast or hair-dryer.
For ease of observing the storage bits situation in storage bits device, described storage bits device adopts transparent material.
The present invention is not limited to described embodiment, and those skilled in the art, not departing from spirit of the present invention namely openly in scope, still can do some and revise or change, therefore the scope that the scope of the present invention limits with claims is as the criterion.
Claims (3)
