Abstract

The utility model discloses an inner hole brush, which comprises clamping strips, bristles (2) and a brush handle (3); the clamping strips comprise four steel wires or stainless steel wires; the inner hole brush is characterized in that the bristles (2) are arranged in double layer, and are arranged in two parallel seams of the four clamping strips (1) in parallel, and the end surfaces of two ends of the bristles (2) are shaped like four spiral belts on the brush surface. The inner hole brush has the following advantages that the bristle density is large, the burr removing function and the rubbing and cleaning function are strong, and the service life is relatively long.

Description

A kind of endoporus brush

Technical field:

The utility model relates to a kind of industrial brushes, relates in particular to remove for the endoporus of metal works the brush that burr rubbing down is used, and is specifically a kind of endoporus brush.

Background technology:

So-called endoporus is brushed, and is mainly used in the endoporus in metal works to remove the brush of burr, rubbing down cleaning use, is called endoporus brush or tube brush in the industry.The endoporus brush of existing product, its brush holder support adopts four clamping strips, and in the time making, its bristle adopts right-angled intersection arrangement mode to be arranged in the right-angled intersection seam of four clamping strips, then by special equipment, brush holder is tightened and installed to clamping strip knot and forms.This endoporus brush, because its bristle is that right-angled intersection shape is arranged, in the right-angled intersection seam of four clamping strips, open ended bristle is relatively less, therefore, deficiency or the defect of its existence be, bristle density is more sparse, it is slightly poor to remove burr ability, and service life is relatively short.

Utility model content:

The technical problems to be solved in the utility model is, the defect or the deficiency that exist for above-mentioned prior art provide a kind of endoporus brush, and this endoporus brushing tool has bristle density large, removes burr, rubbing down cleaning function is strong, the feature of long service life.

Technical solution of the present utility model is:

A kind of endoporus brush, comprise clamping strip, bristle and brush holder, described clamping strip is made up of four steel wires or stainless steel wire, it is characterized in that, described bristle is set in double-deck parallel two parallel seams that are arranged in four clamping strips, and the end face of bristle two ends is four hurricane bands in brush finish.

A preparation method for above-mentioned endoporus brush, comprises the steps:

1., prepare four clamping strips,

2., bristle is implanted in clamping strip,

3., two ends of four clamping strips are tightened,

4., the clamping strip that is implanted with bristle carried out to knob tighten,

5., connect brush holder;

It is characterized in that the above-mentioned the 2. step is divided into bristle in two layers of two parallel seam up and down of implanting respectively four clamping strips.

Compared with prior art, the utlity model has following advantage: bristle density is large, remove burr, rubbing down cleaning function strong, service life is relatively long.

Brief description of the drawings:

Fig. 1 is a kind of endoporus brush configuration of the utility model schematic diagram;

Fig. 2 is that the bristle of a kind of endoporus brush of the utility model is implanted schematic diagram;

Fig. 3 is the cross-sectional structure schematic diagram of Fig. 2 A-A.

Shown in figure: 1, clamping strip, 2, bristle, 3, brush holder.

Detailed description of the invention:

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

As shown in Figure 1, Figure 2 and Figure 3, a kind of endoporus brush, comprise clamping strip 1, bristle 2 and brush holder 3, described clamping strip is made up of four steel wires or stainless steel wire, it is characterized in that, described bristle 2 is set in double-deck parallel two parallel seams that are arranged in four clamping strips 1, and the end face of bristle 2 two ends is four hurricane bands in brush finish.If two layers of bristle 2 adopt different colors, after clamping strip 1 knob is tightened, in brush finish, four hurricane bands very clearly display.

A preparation method for above-mentioned endoporus brush, comprises the steps:

1., prepare four clamping strips,

2., bristle is implanted in clamping strip,

3., two ends of four clamping strips are tightened,

5., connect brush holder;

It is characterized in that the above-mentioned the 2. step is divided into two layers by bristle 2 and implants respectively up and down or in the parallel seam in two of left and right (seeing shown in Fig. 2 and Fig. 3) of four clamping strips 1.

When use, this product is arranged on the chuck of electronic or pneumatic specific purpose tool and is clamped, then, endoporus brush of the present utility model is inserted in metal works endoporus, under the High Rotation Speed of electronic or pneumatic specific purpose tool, bristle is removed burr or is carried out rubbing down processing bore area.

After tested, of the present utility modelly a kind ofly remove for metal works endoporus the brush that burr rubbing down uses and compare with the brush of prior art, its advantage is:

1. the bristle density of the endoporus of the density ratio prior art of bristle brush is high more than 30%;

2. the ability of removing burr is strong, and efficiency is high, and be about 8 seconds the average time in a hole of endoporus brush processing of prior art, and endoporus brush of the present utility model is about 5 seconds;

The life-span of hairbrush long, left and right, 600 holes of the endoporus of prior art brush processing, just scrap, and endoporus of the present utility model brush can be processed left and right, 1100 holes.

Claims

1. an endoporus brush, comprise clamping strip (1), bristle (2) and brush holder (3), described clamping strip is made up of four steel wires or stainless steel wire, it is characterized in that, described bristle (2) is set in double-deck parallel two parallel seams that are arranged in four clamping strips (1), and the end face of described bristle (2) two ends is four hurricane bands in brush finish.
