Description

A kind of polishing sand cotton piece buff suitable for complicated face

Technical field

The present invention relates to sanding and polishing technical field more particularly to a kind of polishing sand cotton piece buffs suitable for complicated face.

Background technique

With the extensive use of built-up welding, consequent is that have many complex-curved built-up welding product sanding and polishings very tired Difficulty, due to hardness of complicated resurfacing welding material of curved surface etc., this work can only be manually completed.The polishing of hand-held sanding and polishing Piece is usually harder, cannot polish with the shape when bent general work, and it is low to cause grinding efficiency, and dead angle of polishing.

Summary of the invention

The present invention provides a kind of polishing sand cotton piece buff suitable for complicated face, and technical solution is as follows:

A kind of polishing sand cotton piece buff suitable for complicated face, including support plate, fitting ring segment, annular gland and ring-shaped sand Round boss is arranged in cloth, support plate centre, and through-hole I is arranged in the center of round boss, and support plate is in the outside of round boss Several internal thread holes are set, and fitting ring segment is made of toughness material, is bonded the internal diameter of ring segment and the outer diameter one of round boss It causes, is bonded the thickness of ring segment and the consistency of thickness of round boss, if the cooperation of several and internal thread hole is arranged in fitting ring segment The internal diameter of dry through-hole II, annular gland is consistent with the internal diameter of through-hole I, and the internal diameter of annular emery cloth is consistent with the internal diameter of through-hole I.

Support plate be bonded ring segment and be fixedly connected by screw, through-hole II and internal thread hole, the cloth cover of annular emery cloth is tight It is affixed on fitting ring segment, annular gland is tightly attached to the sand face of annular emery cloth.Flap wheel is assemblied in using the fastener of angle grinder Sanding and polishing work can be carried out in angle grinder.

Further, annular gland includes annular metal sheet and the annular friction gasket with annular metal sheet adhesion.

Further, fitting ring segment uses hard rubber or hard silica gel material.

Emery cloth, is tightly attached to the fitting ring with toughness by a kind of polishing sand cotton piece buff suitable for complicated face provided by the invention Shape on piece makes flap wheel have toughness, can be in the complex-curved profile-followed polishing of workpiece, and structure is simple, has preferable Application prospect.

Detailed description of the invention

In order to more clearly explain the embodiment of the invention or the technical proposal in the existing technology, to embodiment or will show below There is attached drawing needed in technical description to be briefly described, it should be apparent that, the accompanying drawings in the following description is this hair Bright some embodiments for those of ordinary skill in the art without any creative labor, can be with It obtains other drawings based on these drawings.

Fig. 1 is overall structure diagrammatic cross-section of the invention；

Fig. 2 is the diagrammatic cross-section of support plate of the invention；

Fig. 3 is the diagrammatic cross-section of fitting ring segment of the invention；

Fig. 4 be support plate of the invention be bonded ring segment connection relationship schematic elevation view.

The label of each component in attached drawing are as follows: 1- support plate, 2- are bonded ring segment, 3- annular gland, 4- annular emery cloth, 11- Round boss, 12- through-hole I, 13- internal thread hole, 21- through-hole II, annular metal sheet, 32- annular friction gasket.

Specific embodiment

In order to make the object, technical scheme and advantages of the embodiment of the invention clearer, below in conjunction with the embodiment of the present invention In attached drawing, technical scheme in the embodiment of the invention is clearly and completely described, it is clear that described embodiment is A part of the embodiment of the present invention, instead of all the embodiments.Based on the embodiments of the present invention, those of ordinary skill in the art Every other embodiment obtained without creative efforts, shall fall within the protection scope of the present invention.

As shown in Figure 1, a kind of polishing sand cotton piece buff suitable for complicated face, including support plate 1, fitting ring segment 2, annular pressure Round boss 11 is arranged in lid 3 and annular emery cloth 4, the centre of support plate 1, and through-hole I 12, branch is arranged in the center of round boss 11 Several internal thread holes 13 are arranged in the outside of round boss 11 in fagging 1, and fitting ring segment 2 is made of toughness material, fitting annular The internal diameter of piece 2 is consistent with the outer diameter of round boss 11, is bonded the thickness of ring segment 2 and the consistency of thickness of round boss 11, fitting Several several through-holes II 21 cooperated with internal thread hole 13, the internal diameter of annular gland 3 and the internal diameter of through-hole I 12 is arranged in ring segment 2 Unanimously, the internal diameter of annular emery cloth 4 is consistent with the internal diameter of through-hole I 12.

Support plate 1 be bonded ring segment 2 and be fixedly connected by screw, through-hole II 21 and internal thread hole 13, annular emery cloth 4 Cloth cover is tightly attached to fitting ring segment 2, and annular gland 3 is tightly attached to the sand face of annular emery cloth 4, using the fastener of angle grinder by emery cloth Wheel, which is assemblied in angle grinder, can carry out sanding and polishing work.
