Preferably, the inner edge of the circular ring-shaped sheet structure is fixed on the quick-wire-changing hole mandrel through an adhesive mandrel.

More preferably, two ends of the quick-change thread hole mandrel are flush with the end face of the grinding wheel.

Preferably, both ends of the quick-change thread hole mandrel are opened.

Preferably, the compressed nonwoven fibrous material is compressed from a nonwoven fibrous material.

Preferably, the abrasive particles are alumina abrasive particles, zirconia abrasive particles, ceramic alumina abrasive particles, or silicon carbide abrasive particles.

Preferably, the wool and nylon composite material is formed by compressing wool and nylon fiber materials.

Through the technical scheme, the beneficial effects of the utility model are that:

1. the utility model discloses circle ring shape sheet structure adopts wool and nylon fiber composite, has three-dimensional open space's non-woven fabrics material or the integrative structure that compressed non-woven fabrics material that is stained with abrasive grain made, and circle ring shape sheet structure density is even, and elasticity and flexibility are high, and during the use, the emery wheel outer fringe that forms directly participates in and grinds or polishes the work piece, makes abrasive grain fully participate in grinding or polishing in succession, and is efficient.

2. Compared with the original chuck type grinding wheel of the straight grinding machine, the special fastening flange for dismounting and mounting is not needed when the grinding wheel is replaced; the change of the new grinding wheel and the old grinding wheel can be conveniently and rapidly carried out by an operator in the construction operation process, the time is saved, and the working efficiency is improved.

Detailed Description

The invention will be further explained with reference to the drawings and the detailed description below:

example 1

The embodiment provides a special grinding wheel for a fast-assembly angle grinder, which comprises an embedded quick-change thread hole mandrel 1, an adhesive mandrel 3 and a circular sheet-shaped structure 2 fixed on the outer side of the adhesive mandrel 3. The quick-change thread hole mandrel 1 is provided with openings at two ends and is a metric M14-20 or English 5/8 "-11 quick-change thread hole mandrel 2 made of aluminum alloy or nylon plastic. The quick-change thread hole mandrel 1 is embedded in a grinding wheel and is flush with the end face of the grinding wheel, and is used for connecting various handheld electric or pneumatic angular grinders, electric or pneumatic angular grinders special for various automatic manipulators and handheld electric or pneumatic straight grinders with thread shafts.

The inner edge of the circular sheet-shaped structure 2 is fixed on the quick-wire-changing hole mandrel 1 through an adhesive mandrel 3, and the adhesive is resin adhesive. The inner circle axis of the circular sheet-shaped structure 2 coincides with the axis of the embedded quick-change thread hole mandrel 1, and is the central axis of the grinding wheel.

The circular ring-shaped sheet structure 2 is an integrated structure made of a wool and nylon fiber composite material, a non-woven fiber material with a three-dimensional open space, or a compressed non-woven fiber material adhered with abrasive particles. The circular sheet structure made of the composite material has no grinding function and is mainly used for polishing the surface of a workpiece.

In use, the grinding wheel of the present embodiment is connected to a straight grinder or an angle grinder, and then subjected to polishing work. The outer edge of the grinding wheel directly participates in polishing the workpiece, the annular sheet structure 2 can contact with the polishing part of the workpiece in a large area, and continuously and fully participates in polishing, so that the efficiency is high.

The present embodiment differs from embodiment 1 in that the circular ring-shaped sheet-like structure 2 in this embodiment is a one-piece structure made of a nonwoven fibrous material having three-dimensional open spaces. As shown in FIGS. 1-3. The nonwoven fibrous material having three-dimensional open spaces is prepared from a nonwoven fibrous material impregnated with abrasive particles, which has irregular three-dimensional open spaces. The three-dimensional open space refers to the gaps formed by the mutual staggering of the non-woven fiber materials. The material has high strength and gaps, can efficiently grind the surface of a workpiece, and cannot cause overheating of the surface of the workpiece.

Example 3

As shown in fig. 4, this embodiment is different from embodiment 1 in that the circular ring-shaped sheet structure 2 in this embodiment is made of a compressed nonwoven fiber material adhered with abrasive particles, which is a circular ring-shaped sheet structure made of a compressed nylon nonwoven fiber material, which is a high-density nylon nonwoven fiber material. In this example the abrasive particles are silicon carbide.

The compressed non-woven fiber material is prepared by compressing a nylon non-woven fiber material, has high strength, high density and strong toughness, and abrasive grains adhered on the compressed non-woven fiber material are uniform, so that the compressed non-woven fiber material meets the requirements of grinding operation.

The above-mentioned embodiments are merely preferred embodiments of the present invention, and not intended to limit the scope of the present invention, so that equivalent changes or modifications made by the structure, features and principles of the present invention should be included in the claims of the present invention.
