Abstract
The utility model relates a cutting tool, in particular to a diamond stick-hollowing cutting tool with spiral lines. The diamond stick-hollowing cutting tool comprises a cutter body with a cavity, wherein a cutter holder is arranged on the upper part of the cutter body, a cooling liquid inlet groove is arranged in the cutter holder, the cooling liquid inlet groove is communicated with the cavity in the cutter body, diamond cutting edges distributed evenly are arranged at the bottom of the cutter body, and spiral lines in spiral and continuous distribution are arranged on the inner wall of the cavity of the cutter body. The diamond stick-hollowing cutting tool with spiral lines is simple in structure and is quick in discharging chips, so that the quality of workpieces is improved, and the service life of the cutting tool is prolonged.
Description
Technical field
The utility model patent relates to a kind of cutter, relates in particular to a kind of diamond with helix and draws excellent cutter.
Background technology
What the crystal in the tradition was drawn excellent usefulness at present is a kind of cutter that on the cylindrical metal body, welds diamond grains, because processing request, the diamond grains machined surface requires external diameter greater than outside diameter of cylinder, and the machined surface internal diameter is less than barrel bore.To pour in the cylinder with high-pressure coolant in the processing, go out from the cutting face again, thereby take smear metal out of and cool off cutter and workpiece.Since add man-hour tubular cutter inside and workpiece between formed an enclosure space; High-pressure coolant is difficult to discharge after getting into this space; And, influence Tool advance speed, even because the feeding motor will overcome this active force to reaction force of cutter direction of feed generation; When this active force was too big, system produced and reports to the police.
The utility model content
The utility model mainly is to solve the deficiency that exists in the prior art, provides a kind of simple in structure, can pass through a large amount of high-pressure coolants simultaneously, can reduce reaction force again, makes the cutting feeding draw excellent cutter with the diamond of helix smoothly.
The above-mentioned technical problem of the utility model mainly is able to solve through following technical proposals:
A kind of diamond with helix is drawn excellent cutter; Comprise the cutter hub that has cavity; The top of described cutter hub is provided with handle of a knife, is provided with the cooling fluid inlet slot in the described handle of a knife, and described cooling fluid inlet slot is connected with cavity in the cutter hub; The bottom of described cutter hub is provided with equally distributed diamond blade, and the inwall of described cutter hub cavity is provided with the helix of shape continuous distributed in the shape of a spiral.
Mainly comprise the cylindrical knife shank of forming cutter, cutter hub and diamond blade.Its clamping position cylindrical knife shank and working position diamond blade all are made on the cutter hub.In cylindrical knife shank, have the cooling fluid inlet slot, add man-hour, high-pressure coolant is poured the cutter hub cavity from the cooling fluid inlet, go out from the cutting face again, thereby take smear metal out of and cool off cutter and workpiece.Cut some helixes at the cutter hub inwall; Helix reaches between adjacent two cutting edges along the cutter hub inwall, and the smear metal of blade place generation is when the interstice coverage that is pressed against between the cutting edge like this, and the cooling fluid that just can be rushed out is taken away; High speed rotation along with cutter hub; Cooling fluid in the cutter hub is gone out the processing district along the helix rapid movement with the cooling fluid and the smear metal of front, takes away the heat that a large amount of processing produce simultaneously.Cooling fluid is discharged smoothly fast, and the feed motion of cutter is able to smooth and easy carrying out, and does not have big reaction force; The power of feeding motor also can more effectively be used in the cutting, and obvious like this raising drawn the excellent efficient of drawing of excellent machine, and cooling fluid eliminating speed is relevant with the cutter rotary speed; Speed is high more; Discharge fast more, so the feeding resistance keep basically one constant, can be with velocity variations than great fluctuation process.
As preferably, described helix extends between adjacent diamond blade, and described handle of a knife is cylindrical.
Therefore, the diamond of the band helix that the utility model provides is drawn excellent cutter, and simple in structure, chip removal is rapid, improves workpiece quality, prolongs cutter life.
Description of drawings
Fig. 1 is the structural representation of the utility model.
The specific embodiment
Pass through embodiment below, and combine accompanying drawing, do further bright specifically the technical scheme of the utility model.
Embodiment 1: as shown in Figure 1; A kind of diamond with helix is drawn excellent cutter, comprises the cutter hub 2 that has cavity 1, and the top of described cutter hub 2 is provided with handle of a knife 3; Be provided with cooling fluid inlet slot 4 in the described handle of a knife 3; Described cooling fluid inlet slot 4 is connected with cavity 1 in the cutter hub 2, and the bottom of described cutter hub 2 is provided with equally distributed diamond blade 5, and the inwall of described cutter hub 2 cavitys 1 is provided with the helix 6 of shape continuous distributed in the shape of a spiral; Described helix 6 extends to 5 of adjacent diamond blades, and described handle of a knife 3 is cylindrical.
Claims (2)
1. the diamond with helix is drawn excellent cutter; It is characterized in that: comprise the cutter hub (2) that has cavity (1); The top of described cutter hub (2) is provided with handle of a knife (3), is provided with cooling fluid inlet slot (4) in the described handle of a knife (3), and described cooling fluid inlet slot (4) is connected with cavity (1) in the cutter hub (2); The bottom of described cutter hub (2) is provided with equally distributed diamond blade (5), and the inwall of described cutter hub (2) cavity (1) is provided with the helix of shape continuous distributed (6) in the shape of a spiral.
2. the diamond of band helix according to claim 1 is drawn excellent cutter, it is characterized in that: described helix (6) extends between adjacent diamond blade (5), and described handle of a knife (3) is cylindrical.
