Description

A kind of fluted drill grinding tool

Technical field

The utility model is related to process equipment field, more particularly to a kind of fluted drill abrasive article structures.

Background technology

At present, grinding tool sharpening means are inclined to the two poles of the earth, big for sharpening demand, it typically can all use tool sharpening machine Bed, it is multiple functional, but price ten thousand yuan to hundreds of thousands member between, if sharpening tool category it is single, buy one sharpening Lathe can also highlight that cost performance is not high, the superfluous shortcoming of function；Small for sharpening demand, one lathe of purchase is substantially more It is remaining, so ground by hand using angle grinder as most common selection, but hand grinding needs the skill and experience by people, not only Efficiency is low, and reliability can not be guaranteed.

The content of the invention

The technical problems to be solved in the utility model, is to provide a kind of new fluted drill grinding tool, solves prior art Sharpen cost it is high, it is inconvenient for use the problem of.

What the utility model was realized in：

A kind of fluted drill grinding tool, including cutter head and knife bar, the cutter head include blade, blade；The bottom surface of the blade It is connected with knife bar, the bottom surface connection of upper bottom surface and blade, the blade also includes the institute a little position on cut surface, the cut surface In the same conical surface, the distance of the bottom surface at cut surface center to blade is less than distance of remaining point to the bottom surface of blade on cut surface.

Further, the blade is multiple, and blade Central Symmetry on blade is arranged.

Further, in addition to hole, the bottom surface and upper bottom surface of hole UNICOM blade, hole is in blade bottom surface Opening positioned at multiple blades interstitial site.

Specifically, in addition to spring, the periphery of knife bar also includes locating part, and the spring is socketed in outside knife bar, the bullet One end of spring and blade against, the other end and locating part against.

Further, the upper bottom surface of the blade also includes groove, and the side wall of blade is provided with the through hole with groove UNICOM, knife Bar is also provided with knife bar hole, in addition to bolt, nut, and the bolt is passed after passing through through hole, knife bar hole from the opposite side of blade, with Nut is fixed.

Preferably, the diameter in the knife bar hole is equal with bolt, the through hole it is tall and big in the diameter of bolt, width and bolt Diameter is equal.

The utility model has the following advantages that：Make simple, it is easy to use, tear open with preferable grinding function and conveniently Unload.

Embodiment

To describe technology contents of the present utility model, construction feature, the objects and the effects in detail, below in conjunction with implementation Mode simultaneously coordinates accompanying drawing to be explained in detail.

Refer to Fig. 1 and Fig. 2, a kind of schematic diagram of fluted drill grinding tool of the utility model, including cutter head 5 and knife bar 1, institute Stating cutter head includes blade, blade；The bottom surface of the blade is connected with knife bar, the bottom surface connection of upper bottom surface and blade, the knife Sword also includes being located at the same conical surface, the distance of the bottom surface at cut surface center to blade a little on cut surface, the cut surface Less than distance of remaining point to the bottom surface of blade on cut surface.Blade is the thick structure in intermediate thin both sides, can well with fiber crops The structure that flower is bored is adapted, when grinding tool works, and fluted drill is fixed on into workbench, starts drilling machine, and operation drilling machine makes mill Tool is slowly fitted, and completes the grinding of fluted drill cutting edge.

Further, in order to ensure drilling machine operationally uniform force, the blade is multiple, and the blade is on blade Central Symmetry is arranged.Have gap between multiple blades, can relative to one blade save some materials, multiple drilling machines are symmetrically arranged Row enable to grinding tool to be unlikely to eccentric when rotated, preferably drill bit can be cut, preferably solve fluted drill The problem of tool design.

In some further embodiments, in addition to hole, as shown in figure 1, the bottom surface of hole UNICOM blade With upper bottom surface, hole is located at the interstitial site of multiple blades in the opening of blade bottom surface.The effect of hole can for drainage, Specifically, the state of grinding tool rotate at high speed is contacted with fluted drill, while larger heat can be produced, can now be worked in grinding tool Coolant is drained at grinding tool cutter head high temperature from hole simultaneously, unnecessary drainage-fluid can be then thrown out of in knife-edge gap.Only need Coolant is slowly injected in the upper bottom surface of blade, preferably reach the problem of fluted drill grinding tool is cut.

In specific embodiment as shown in Figure 2, in addition to spring 2, the periphery of knife bar also includes locating part, the bullet Spring is socketed in outside knife bar, one end of the spring and blade against, the other end and locating part against.The spring is compression bullet Spring, by spring against blade, knife bar, spring provides an outside thrust to cutter head, in actual use can be by mould With fluted drill automatic aligning, the working time is saved, operating efficiency is improved.

In a further embodiment, as shown in Fig. 2 the upper bottom surface of the blade also includes groove, the side wall of blade is opened There is the through hole with groove UNICOM, knife bar 1 is also provided with knife bar hole, in addition to bolt 4, nut 3, and the bolt 4 passes through through hole, knife bar The opposite side of Kong Houcong blades is passed, and is fixed with nut 3.Fig. 2 it can be clearly seen that, bolts and nuts are by knife bar hole by knife Bar is fixed up, when bistrique is disassembled, it is only necessary to which screw bolt and nut is opened, the just automatic release of spring 2, knife bar 1, cutter head 5 , it is such to design the effect for having reached and being convenient for people to assemble, install.

In the preferred embodiment shown in Fig. 2, the diameter in the knife bar hole is equal with bolt, the through hole it is tall and big in The diameter of bolt, width is equal with the diameter of bolt.Knife bar bore dia is equal with bolt so that knife bar can be clamped securely to bolt On, through hole can be designed as slotted hole, and its height is more than the diameter of bolt so that bolt has up and down freedom in through-holes Degree, in some specific embodiments, compression spring 2 in its natural state ejects forward cutter head 5, now bolt, knife bar hole with The lower end alignment of through hole, now drilling machine drive grinding tool starts to rotate at a high speed, and operation drilling machine makes it slowly close to fluted drill, complete Start the grinding of blade when touching fluted drill；Grinding tool cutter head in work is slow and fluted drill is contacted, mutual power after contact Cutter head displacement is caused further to compress spring, bolt and nut is moved to slotted hole upper end, and cushion stroke is provided for cutter head, this When cutter head at drainage trough drainage coolant to be ground high temperature at cool；After work, by grinding tool slowly away from fluted drill, now grinding tool State before work is returned to, the grinding of fluted drill blade is completed.Formed by designing buffering, the utility model can preferably protect fiber crops Flower brill will not fracture because of external force, preferably reach the effect of spiral bit skiving.

Embodiment of the present utility model is the foregoing is only, scope of patent protection of the present utility model is not thereby limited, Equivalent structure or equivalent flow conversion that every utilization the utility model specification and accompanying drawing content are made, or directly or indirectly fortune Used in other related technical fields, similarly it is included in scope of patent protection of the present utility model.
