Abstract

The utility model relates to the technical field of polishing tools, and discloses a self-adaptive polishing sheet for solving the technical problems of self-adaptability of a polishing sheet to polishing force and easiness in automatic sheet replacement, wherein the self-adaptive polishing sheet comprises a substrate, wherein the substrate is made of a hard elastic high polymer material or an elastic metal material; and a grinding layer is arranged on the substrate. The marginal zone of self-adaptation piece of polishing is as work area, and when the power of polishing is great, the self-adaptation piece of polishing can avoid great and damage workpiece surface with the pressure that workpiece surface hard contact produced through taking place deformation, and the power of polishing keeps even, and deformation makes area of contact increase moreover, has still improved the efficiency of polishing. Self-adhesion grinds the layer, and the commutation is very convenient and fast, not only is applicable to manual operation of polishing but also is applicable to the automatic operation of polishing.

Description

Self-adaptive polishing sheet

Technical Field

The utility model relates to the technical field of polishing tools.

Background

Present polishing piece is mostly glass fiber polishing piece, and not only the fragility is great, when the dynamics of polishing is great moreover, harms workpiece surface easily and causes the workpiece surface unevenness of polishing, sees that figure 1 shows. In addition, because the existing polishing plate is pressed and fixed on the polishing machine by adopting a nut, the automatic plate replacement is difficult to realize, and the automatic polishing plate is difficult to apply in automatic polishing.

SUMMERY OF THE UTILITY MODEL

Aiming at the defects of the prior art, the utility model provides a polishing sheet, which solves the technical problems of self-adaptability of the polishing sheet to polishing force and realization of automatic sheet replacement.

In order to solve the technical problem, the utility model adopts the following technical scheme: a self-adaptive polishing plate comprises a substrate, wherein the substrate is made of a hard elastic high polymer material or an elastic metal material; and a grinding layer is arranged on the substrate.

Preferably, the substrate is pasted with a flocked abrasive paper sheet through a magic tape self-adhesive disc to form the abrasion layer.

Compared with the prior art, the utility model has the following beneficial effects:

1. because the substrate adopts and to make with elastic material, the marginal area of self-adaptation piece of polishing is as work area, and when the power of polishing is great, the self-adaptation piece of polishing can avoid the great and damage workpiece surface with the pressure that workpiece surface hard contact produced through taking place deformation, and the power of polishing keeps even, and deformation makes area of contact increase moreover, has still improved the efficiency of polishing.

2. The substrate combines the grinding layer through the mode of pasting, and after grinding the layer became invalid, tear the grinding layer after becoming invalid, paste new grinding layer interface again and accomplish the retooling, very convenient and fast is applicable to the automation operation of polishing.

FIG. 1 is a diagram of a prior art sanding block in operation;

FIG. 2 is a schematic structural diagram of an adaptive sanding sheet in accordance with the present embodiment;

fig. 3 is a diagram illustrating the operation of the adaptive sanding block in this embodiment.

Detailed Description

The present invention will be described in further detail with reference to the accompanying drawings and preferred embodiments.

Referring to fig. 2, an adaptive polishing pad includes a substrate 4, wherein the substrate 4 is made of a hard elastic polymer material (such as a hard elastic polypropylene material or a nylon material) or an elastic metal material (such as an elastic steel); and a grinding layer is arranged on the substrate.

The sharpening layer can be arranged on the substrate in two ways:

1) the substrate 4 is pasted with flocked abrasive paper sheets 1 through the magic tape self-adhesive disc 2 to form the grinding layer.

2) And diamond grains are sprayed on the substrate to form the grinding layer. Preferably, diamond grit is sprayed along the edge region of the substrate to form an annular abrasive layer.

The substrate passes through connection piece 5 to be connected on the power shaft of polisher, and 5 one sides of connection piece are equipped with the connecting seat, are equipped with the shaft hole in the connecting seat. In order to improve the coaxiality of the installed polishing piece and the power shaft: the other side of the connecting piece is provided with a positioning ring concentric with the shaft hole, and the positioning ring protrudes out of the connecting piece; the center of the substrate is provided with a positioning hole and is sleeved on the positioning ring through the positioning hole. The base plate 4 is detachably connected to the connecting piece 5 by means of screws 3 distributed around the positioning holes.

Referring to fig. 3, when the adaptive polishing pad of the present invention polishes a surface of a part, an edge region of the adaptive polishing pad serves as a working region, and when a polishing force is large, the adaptive polishing pad can deform to prevent the surface of the workpiece from being damaged due to a large pressure generated by hard contact with the surface of the workpiece, so that the polishing force is uniform, and the deformation increases a contact area, thereby improving polishing efficiency.

The substrate combines the grinding layer through the mode of pasting, and after grinding the layer became invalid, tear the grinding layer after becoming invalid, paste new grinding layer interface again and accomplish the retooling, very convenient and fast is applicable to the automation operation of polishing.
