Description

Burr removes cutter

Technical field

Basis is practical newly relates to a kind of burr remover, particularly relates to burr and removes cutter.

Background technology

Because numerical control machining center can be processed by the high efficiency workpiece high to complex structure, required precision, numerical control machining center can adapt to various different part and changes simultaneously, and the writing of procedure also can complete in conjunction with relevant Numerical Control Simulation software.Normally treat the processing that machined surface carries out little cutting output at high speeds in digital control processing for this reason, but it is few for this chip surplus, the combination of machined surface and non-machined surface goes out can exist burr, if do not cleared up, in use procedure, burr can affect the use of machined surface, is difficult to meet the assembly precision in use procedure and easy scratch operating personnel.

The mode of common deburring adopts file to carry out grinding process to burr, inefficiency like this, and cost of labor is high, and precision also can be difficult to control because of artificial adjustment.

The patent No. is that the Chinese patent literature of CN203449113U discloses a kind of deburring hairbrush, comprise fixed axis, described fixed axis lower end is provided with woollen brush base, and described woollen brush base lower end is provided with the hairbrush disk that can dismantle, and described hairbrush disk lower end is provided with multiple abrasive filaments bristle stretched out.

Not pointing out the material of hairbrush in above-mentioned patent document, do not point out the annexation of hairbrush and machine tool chief axis, simultaneously because the length of hairbrush is non-adjustable, needing the hairbrush of the deburring under different condition to formulate plurality of specifications hairbrush, cost seeming too high.

Utility model content

The purpose of this utility model is that solving current burr removes the problem that on cutter, abrasive brush staple length is adjustable.

In order to solve the problem, the utility model proposes a kind of burr and remove cutter, comprise handle of a knife, one end of handle of a knife is fixedly connected with woollen brush base, woollen brush base end protrudes from some abrasive material bristles, also comprise handle of a knife, brush plate, described handle of a knife comprises handle of a knife axle, clamping part, connecting portion, woollen brush base is axially connected with connecting portion in turn, clamping part, handle of a knife axle, the periphery of handle of a knife axle is the Morse's taper periphery matched with machine tool mount pad, brush plate offers the hole corresponding with abrasive material bristle, what brush plate can move axially is fixedly connected on woollen brush base.

In such scheme, handle is adopted to be waste and old tool handle, be connected on woollen brush base, Morse's taper periphery on tool handle can complete and coordinate with the installation of lathe, clamping part between Handle axis and connecting portion can be convenient to completing of the automatic switchover cutter of Digit Control Machine Tool, connecting portion can be convenient to the processing of clamping part, brush plate offers the hole corresponding with abrasive material bristle, brush plate can axial spacing regulate be fixedly connected on woollen brush base, brush plate can regulate according to different processing situations the length protruded from, improve stressed in deburring process of abrasive material bristle, and adjust according to the difference in hole to be gone and face the length that abrasive material bristle protrudes from the abrasive material bristle of brush plate, to realize the length adjustment of different processing conditions, woollen brush base also can remove the burr chip be mingled with between hairbrush in the moving process of axis simultaneously.

Further optimization, abrasive material bristle comprises rubber hairbrush and hard particles, hard particles is attached to rubber hairbrush outer surface, the hardness of particle is greater than 55HRC, utilize rubber hairbrush for matrix, abrasive material bristle has certain toughness, can regulate distortion voluntarily with different arch area territories, reduce because bristle core scratch machined surface really up to the mark, the hard particles only utilizing hardness to be greater than 55HRC carries out friction treatment to burr, burr.

Further optimization, spacing between adjacent grits bristle is for being greater than 4mm, and the burr length of the cutting remnants of common cutter is less than 4mm, and the spacing being greater than 4mm can reduce burr and be stuck between abrasive material bristle, the automatically cleaning ability of abrasive material bristle can be improved, reduce and think that removing iron is cut, the amount of labour of burr.

Further optimization, be fixedly connected as some bolts to connect, bolt connects circle distribution on woollen brush base, be fixedly connected as bolt and connect the spacing can be convenient between dismounting adjustment woollen brush base and brush plate, bolt connects circle distribution on woollen brush base simultaneously, and woollen brush base, in the process of High Rotation Speed, can restrict between some bolts mutually, prevent bolt falling, improve stability.

Further optimization, clamping part is annular groove, annular groove can coordinate the capstan head of numer centre to coordinate the replacing realizing cutter, to realize the NC postprocessing of cutter, deburring program burr being removed cutter is listed in nc program, carries out one-time positioning and completes processing, and utilize nc program to complete deburring to workpiece, process velocity is fast, estimates one's own ability and can control.

Accompanying drawing explanation

Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail:

Fig. 1 is structural representation of the present utility model;

Fig. 2 is the structural representation after the utility model brush plate regulates;

Fig. 3 is the partial enlarged drawing at the A place of Fig. 1;
