Abstract

The utility model discloses the design scheme of an elastic grinding head; an existing grinding tool is not suitable for grinding an arced surface, a concave surface, or a convex surface, the work efficiency is low, and the grinding quality is bad. The elastic grinding head is composed of an elastic basal body, a connecting head, an elastic sand cloth, elastic velour pieces, etc.; the elastic grinding head can be connected with various power heads to grind and polish various flat surfaces, especially the arced concave surfaces and the convex surfaces; the utility model has the advantages of flexible operation, small vibration, low noise, high work efficiency, and good grinding quality; the utility model can be widely used for the industries of automobiles, motorcycles, tractors, machine manufacturing, architecture construction materials, furniture, etc.

Description

Spring grinding head

The utility model belongs to the machinery of grinding or polishing, a kind of grinding, polishing metal, nonmetal arcwall face and plane Spring grinding head.

Existing grinding facility, as incompatibility grinding arc, concave surface, convex surfaces such as abrasive machine, belt sanders, and noise is big, power consumption is high, and then labour intensity is big, work efficiency is low and of poor quality for hand grinding.The inventor has obtained patent " multi-functional mantle air cushion Grinding and polishing machine " though can be suitable for the grinding arcwall face, and making to use has certain limitation.

The purpose of this utility model is a kind of grinding-polishing machinery of design, makes its energy high-quality and high-efficiency ground grinding arc, concave surface, convex surface and plane, and easy to manufacture easy to use.

The purpose of this utility model reaches by the design of following Spring grinding head.It is made up of matrix, coupling head, abrasive disc, suede sheet.Matrix is the elastomer with solid or hollow inflation that certain elasticity, intensity and wear heat-resistant material make.Be equipped with the elasticity emery cloth on the matrix and can be used for grinding, be equipped with the suede sheet and can be used for polishing.The elasticity emery cloth is done basic unit by the material with certain elasticity and intensity, and is multiple more above with many little sand lumps compositions, also little sand lump directly can be bonded on the matrix.Be provided with the gap between little sand lump; Elasticity suede sheet is made of basic unit with certain elasticity and intensity, wear heat-resistant material making and the waste pad of answering in basic unit.As required, elasticity emery cloth and elasticity suede sheet can be made into garden shape, band shape and tubular, also can be processed into cone-shaped or other is special-shaped.

Select Fig. 1, Fig. 2 to be the utility model summary figure.

Fig. 1～Figure 10 is several embodiment of the present utility model.

Below in conjunction with accompanying drawing, be described further.

Fig. 1 is the solid elastomeric bistrique.Form by elastic matrix 1, coupling head 2, cancave cambered surface 3, matrix velcro 4, elasticity sand sheet basic unit 5, grinding layer 6, clearance gap 7, sand sheet velcro 8 etc.Elastic Circular sand sheet is bonding by velcro and elastic matrix, and elastic matrix is assembled on the unit head with coupling head 2, and the head that turns on the power, elasticity sand sheet promptly rotate with matrix, to the work grinding of fitting.If need polishing, take off the sand sheet and change the suede sheet, coat antiscuffing paste and can polish workpiece.

Fig. 2 is the inflatable elastic bistrique, is made up of bell-type steel ring 9, valve 10, hoop skin ring 11, coupling head 2, elasticity moccasin 12, air cavity 13 etc.After the air cavity inflation, the elasticity moccasin can reach needed inflatable elastic matrix cambered surface within the specific limits.Elasticity emery cloth and elasticity suede sheet are bonding with velcro and elastic matrix.

The convex arc bistrique is used for polishing polishing concave arc workpiece, and the concave arc bistrique is used for the convex arc workpiece.Concave arc and convex arc colyliform matrix can be assembled into the elasticity belt sander respectively, or are assembled on the lathe with single concave arc or convex arc colyliform matrix, make the Spring grinding head lathe.

The utility model has the advantages that compact conformation, mounting or dismounting conveniently, can polish high-quality, efficiently the various arc-shaped concaves of polishing, convex surface, and can be assembled into respectively the elasticity belt sander with concave arc or convex arc colyliform matrix, and be assembled on the lathe with single concave arc colyliform matrix, can be made into the Spring grinding head lathe.

Claims
