Abstract
The utility model discloses a grinding tool, in particular to a grinding head which comprises a main shaft part and a grinding head part, wherein one end of the grinding head is fixedly connected with the main shaft part, cutting edges are arranged on the grinding head part, the section of the grinding head part is a circular, a scrap outlet groove is formed between each two cutting edges, and the depth of the scrap outlet groove is matched with the radius of the grinding head part. During the process of workpiece processing, under the driving of the high speed rotating grinding head, the workpiece scrap falls in the scrap outlet groove with the action of centrifugal force, as the depth of the scrap outlet groove is matched with the radius of the grinding head part, the grinding head discharges the processed workpiece scrap in the scrap outlet groove during high speed rotation, so as to avoid scrap pilling which affects cutting work of the cutting edges.
Description
Technical field
The utility model relates to a kind of milling drum instrument, and more particularly, it relates to a kind of bistrique that the chip of workpiece to be machined can be discharged.
Background technology
It is the minor diameter revolution bodily form grinding tool of blind mouthful that bistrique is generally the grinding machine components that grinding wheel spindle is housed and makes its rotation or centre bore, often coheres on metal handle and uses.Be contained on lathe or handheld tool when bistrique uses and make High Rotation Speed, be mainly used in the inside and outside contour of reconditioning profile, as the various punch dies of reconditioning etc.Bistrique is a kind of general name of mini zone handle grinding tool, is applied to electrical grinding machine, hangs grinding machine, electric hand drill.
The grinding tool of serving at present mechanical industry mainly is comprised of the main shaft part that is fixedly connected with and bistrique section, and bistrique section mostly is the emery wheel of rigidity.It is effective to ferrous metal, but non-ferrous metal and nonmetallic materials are just seemed helpless.Therefore, desirable grinding tool that is applicable to the non-ferrous metal products burr of searching is just particularly important.The general character of non-ferrous metal is that hardness is low, plasticity is good, as aluminium, magnesium, copper, lead, zinc etc.Take aluminium as example, when the emery wheel that rotates contacts with aluminium, because both intensity differ greatly, abrasive particle on emery wheel seldom is worn away, and the good aluminium of plasticity bits are embedded between the sand grains gap, after the gap was filled, emery wheel had just lost ablation, and Here it is, and emery wheel can not be for the reason of grinding soft metal.
The existing bistrique of making according to the operation principle of milling cutter, this kind bistrique can cut the burr on the soft metal, but because sawtooth is larger, will cause larger vibrations when work, and rough smooth after the part milling.
The utility model content
For the deficiency that prior art exists, the purpose of this utility model is to provide a kind of bistrique that can discharge the workpiece to be machined chip.
For achieving the above object, the utility model provides following technical scheme:
A kind of bistrique includes main shaft part and bistrique section, and bistrique section one end is fixedly connected with main shaft part, be provided with cutting blade in bistrique section, the cross section of described bistrique section is circular, is separated with flute between between described cutting edge, and the radius of the degree of depth of described flute and bistrique section is suitable.
By adopting technique scheme, when processing work, workpiece debris is under the bistrique that runs up drives, because the effect of centrifugal force drops in flute, because the degree of depth of flute equates with the radius of bistrique section, when bistrique runs up, the workpiece to be machined chip in flute is discharged, thereby avoided the work of talus accumulation impact cutting cutting edge.
As further improvement in the technical proposal:
Described bite arrangement mode is swirl shape.
The arrangement mode of described flute is consistent with the cutting edge arrangement mode.
By adopting technique scheme, add man-hour bite and flute all spiral yarn shaped being arranged in add man-hour, the characteristic of utilizing spiral with the workpiece debris on cutting edge in better discharge.
The utility model further is set to:
Described cutting edge is made of wolfram steel.
By adopting technique scheme, bite adopts the high and wolfram steel that be not afraid of wearing and tearing of hardness to consist of, and has strengthened the fastness of bistrique.
Description of drawings
Fig. 1 is the stereogram of the utility model bistrique;
Fig. 2 is the A section enlarged drawing of the utility model bistrique.
Reference numeral:
1, main shaft part; 2, bistrique section; 3, cutting edge; 4, flute.
The specific embodiment
Referring to figs. 1 through Fig. 2, the utility model bistrique embodiment is described further.
As extremely shown in Figure 2 in Fig. 1, the utility model bistrique, include main shaft part 1 and bistrique section 2, bistrique section 2 one ends are fixedly connected with main shaft part 1, be provided with cutting blade in bistrique section 2, the cross section of described bistrique section 2 is circular, is separated with flute 4 between between described cutting edge 3, and the radius of the degree of depth of described flute 4 and bistrique section 2 is suitable.
By adopting technique scheme, when processing work, workpiece debris is under the bistrique that runs up drives, because the effect of centrifugal force drops in flute 4, because the degree of depth of flute 4 radius with bistrique section 2 equates, when bistrique runs up, the workpiece to be machined chip in flute 4 is discharged, thereby avoided 3 work of talus accumulation impact cutting cutting edge.
As shown in Figure 2,3 one-tenth swirl shapes of described cutting edge are arranged.The arrangement mode of described flute 4 is consistent with cutting edge 3 arrangement modes.By adopting technique scheme, add man-hour bite and flute 4 all spiral yarn shaped being arranged in add man-hour, the characteristic of utilizing spiral with the workpiece debris on cutting edge 3 in better discharge.
Described cutting edge 3 is made of wolfram steel.Bite adopts the high and wolfram steel that be not afraid of wearing and tearing of hardness to consist of, and has strengthened the fastness of bistrique.
The above is only preferred embodiment of the present utility model, and protection domain of the present utility model also not only is confined to above-described embodiment, and all technical schemes that belongs under the utility model thinking all belong to protection domain of the present utility model.Should be pointed out that for those skilled in the art, in the some improvements and modifications that do not break away under the utility model principle prerequisite, these improvements and modifications also should be considered as protection domain of the present utility model.
