Abstract
The utility model relates to an automatic tensioning abrasive belt wheel used for grinding. A rubber wheel is arranged on a metallic frame work of the utility model; the middle part of the rubber wheel is provided with more than one slotted holes which can be inclined along the center line of a wheel shaft; the periphery of the rubber wheel is provided with more than one skew tooth; an abrasive belt is installed on a cylinder surface which is composed of the skew teeth. The utility model has the advantages of small size, simple structure, convenient installation, low cost and capability of grinding hard materials and flexible materials.
Description
The utility model relates to a kind of abrasive belt grinding and polishing tool, and it is particularly related to a kind of abrasive belt wheel that can auto-tensioning.
Before the utility model proposes, generally use as grinding tool in the abrasive band, generally is that the abrasive band is enclosed within on contact wheel and the regulating wheel, makes its tensioning with strainer, and entire mechanism is comparatively complicated, and cost is higher, and is bulky.In the use, ground effect is undesirable.
The purpose of this utility model is to provide a kind of simple in structure, easy for installation, cheap abrasive belt wheel that can auto-tensioning.
The purpose of this utility model can realize by following technical measures.
This abrasive belt wheel, its metallic framework is provided with rubber wheel, is provided with the more than one slotted eye that tilts along axle centre at the middle part of rubber wheel, in the periphery of rubber wheel more than one helical teeth is arranged.The abrasive band is installed on the face of cylinder of being made up of helical teeth.
The slotted eye of above-mentioned abrasive belt wheel evenly is arranged in the middle part of rubber wheel obliquely.Its number and size are determined according to the diameter of abrasive belt wheel.Helical teeth (4) is arranged in the periphery of rubber wheel equably, its helical angle be 8 degree to 45 degree, helical teeth be shaped as a kind of or its combination in rectangle, zigzag, spoon shape, the X zigzag.Its number and size are also determined according to the diameter of abrasive belt wheel.
Operation principle of the present utility model is, abrasive belt wheel is along certain direction rotation, and centrifugal force makes rubber produce bigger tension, thereby the external diameter when making abrasive belt wheel work becomes big, makes the abrasive band swelling that is enclosed within on the cylindrical.When workpiece carried out grinding or polishing on the abrasive band, active force made the slotted eye that favours axle centre produce deformation, and the abrasive belt wheel radius increases, and active force is also bigger, and the abrasive band is expanded tightly more.The helical tooth on surface, abrasive band can improve the tractive force to the abrasive band.Simultaneously, according to the mechanism of sbrasive belt grinding, the effect of helical tooth can strengthen the cutting effect in abrasive band, reduces the obstruction of grinding, improves the service life in abrasive band, realizes the purpose of this utility model.
The utility model has following advantage compared with the prior art:
1. volume is little, and is simple in structure, easy for installation, cheap.
Since rubber from flexible, not only can grinding hard material such as metal, can also grinding soft material such as timber, leather etc.
Description of drawings of the present utility model:
Fig. 1: front view of the present utility model.
Fig. 2: cutaway view of the present utility model.
Fig. 3: the partial view of helical teeth of the present utility model.
Embodiment of the present utility model.
Referring to specification book accompanying drawing 1-3.The abrasive belt wheel of this auto-tensioning, its metallic framework (1) is provided with rubber wheel (2), is provided with the more than one slotted eye (3) that tilts along axle centre at the middle part of rubber wheel, in the periphery of rubber wheel more than one helical teeth (4) is arranged.Slotted eye (3) evenly is arranged in the middle part of rubber wheel obliquely.Helical teeth (4) is arranged in the periphery of rubber wheel equably, its helical angle be 8 degree to 45 degree, helical teeth be shaped as a kind of or its combination in rectangle, zigzag, spoon shape, the X zigzag.The direction of arrow indication is the direction of rotation of abrasive belt wheel among Fig. 1.
Wherein, metallic framework (1) can adopt the aluminium alloy manufacturing, and rubber wheel can be by the model manufacturing.The number of slotted eye, helical teeth and size can be determined according to the diameter of abrasive belt wheel.This product is directly installed on the motor rotary shaft, and the surface is installed the abrasive band and can be used.
Claims (4)
- The abrasive belt wheel of 1 one kinds of auto-tensionings, its metallic framework (1) is provided with rubber wheel (2), it is characterized in that being provided with the more than one slotted eye (3) that tilts along axle centre, more than one helical teeth (4) is arranged in the periphery of rubber wheel at the middle part of rubber wheel.
- The abrasive belt wheel of 2 a kind of auto-tensionings according to claim 1 is characterized in that wherein said slotted eye (3) evenly is arranged in the middle part of rubber wheel obliquely.
