Description

Technical Field

[0001] This utility model relates to the field of polishing tool technology, and in particular to a polishing disc for rapid polishing. Background Technology

[0002] A polishing disc is a disc-shaped tool mounted on polishing equipment (such as an angle grinder or polishing machine) to hold polishing materials (such as polishing wax or abrasive paste) and rub against the surface of a workpiece to remove scratches and improve its smoothness. It typically includes a base for connecting to the rotating shaft of the polishing equipment and a polishing layer disposed on the base.

[0003] Currently, the basic structure of polishing pads used for rapid polishing on the market typically includes a rigid plastic or metal base. A polishing pad made of sponge, wool, or composite fibers of a certain thickness and elasticity is fixed to the working surface of the base using adhesive or mechanical clips. The base has a threaded hole or quick-connect mechanism in the center for connecting to the polishing machine's spindle. This structure adapts to the contours of the workpiece surface through the elastic deformation of the polishing pad.

[0004] However, existing polishing pads used for rapid polishing have the problem that the heat and polishing debris generated during the polishing process are difficult to dissipate quickly, which will accelerate the clogging and aging of the polishing pad and shorten its service life. Utility Model Content

[0005] The purpose of this invention is to provide a polishing pad for rapid polishing, which solves the problem that existing polishing pads used for rapid polishing have difficulty in quickly dissipating the heat and polishing debris generated during the polishing process, which accelerates the clogging and aging of the polishing pad and shortens its service life.

[0006] To achieve the above objectives, this utility model provides a polishing disc for rapid polishing, comprising a base and a polishing pad. A connecting protrusion is provided at the center of one side of the base, and a connecting hole is provided on the connecting protrusion for connecting the rotating shaft of a polishing device. A mounting groove is provided on the other side of the base, and the polishing pad is disposed inside the mounting groove. The polishing pad is made of a breathable porous elastic material. An annular groove is provided at the bottom inner part of the mounting groove, and multiple raised reinforcing ribs are evenly arranged inside the annular groove, dividing the annular groove into multiple independent fan-shaped areas. A first through hole is provided at the center of each fan-shaped area, and each first through hole penetrates the base. The end face of the polishing pad extends to the outside of the mounting groove, and the outer wall of the mounting groove has a hollow structure.

[0007] The hollow structure of the outer wall of the mounting groove consists of multiple second through holes evenly distributed along the circumference, which connect the inside and outside of the mounting groove.

[0008] Each of the second through holes is an elongated hole, and the length direction of each second through hole is parallel to the axial direction of the base.

[0009] The top of each reinforcing rib is flush with the inner bottom surface of the mounting groove, and the polishing pad is attached and fixed to the inner bottom surface of the mounting groove and the top of the multiple reinforcing ribs by adhesive.

[0010] The polishing pad is made of porous polyurethane, porous rubber, or a porous polymer composite material reinforced with fibers.

[0011] The thickness of the portion of the polishing pad extending outside the mounting groove is 1 / 5 to 1 / 3 of the total thickness of the polishing pad.

[0012] Each of the first through holes has a first slot on the side away from the mounting groove, and each of the first slots has a first protective net.

[0013] Each of the second through holes has a second slot on the side away from the mounting groove, and a second protective net is provided at each of the second slots.

[0014] The first protective net and the first card slot, as well as the second protective net and the second card slot, are detachable snap-fit ​​connections.

[0015] The connecting protrusion is cylindrical or frustum-shaped, and its outer periphery is provided with multiple anti-slip ridges extending axially.

[0016] This invention discloses a rapid polishing disc, comprising a base and a polishing pad. The base has a mounting groove on its end face, and the polishing pad is disposed inside the mounting groove. The polishing pad, made of a breathable porous elastic material, serves as the first layer of channels, allowing heat and debris to be transferred vertically downwards. The annular groove at the bottom and the reinforcing ribs form multiple independent fan-shaped flow chambers, which, together with the first through-hole penetrating the base, efficiently remove accumulated debris under centrifugal force. Simultaneously, the hollowed-out sidewalls of the mounting groove constitute radial exhaust channels, allowing heat and debris from the edge areas to be directly discharged from the sides. This dual-path design, combining vertical and radial paths, significantly enhances airflow and debris removal efficiency, effectively preventing localized blockages and heat accumulation, thereby delaying the performance degradation of the polishing pad and extending its service life.

Detailed Implementation

[0023] The embodiments of the present invention are described in detail below. Examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, but should not be construed as limiting the present invention.

[0024] Please see Figures 1 to 4 This utility model provides a rapid polishing disc, which includes a base 101 and a polishing pad 102. A connecting protrusion 103 is provided at the center of one side of the base 101, and a connecting hole 104 is provided on the connecting protrusion 103 for connecting the rotating shaft of a polishing device. A mounting groove 105 is provided on the other side of the base 101, and the polishing pad 102 is disposed inside the mounting groove 105. The polishing pad 102 is made of a porous elastic material with breathability. An annular groove 106 is provided at the bottom of the mounting groove 105. Multiple raised reinforcing ribs 107 are evenly arranged inside the annular groove 106. The multiple reinforcing ribs 107 divide the annular groove 106 into multiple independent fan-shaped areas 108. A first through hole 109 is provided at the center of each fan-shaped area 108. Each first through hole 109 penetrates the base 101. The end face of the polishing pad 102 extends to the outside of the mounting groove 105. The outer wall of the mounting groove 105 is provided with a hollow structure.

[0025] In this embodiment, the polishing pad 102, made of a breathable porous elastic material, serves as the first layer of channels, allowing heat and debris to be transferred vertically downwards. The annular groove 106 at the bottom and the reinforcing rib 107 form multiple independent fan-shaped flow chambers, which, together with the first through hole 109 penetrating the base 101, efficiently remove accumulated debris under centrifugal force. Simultaneously, the hollowed-out sidewalls of the mounting groove 105 constitute radial exhaust channels, allowing heat and debris from the edge area to be directly discharged from the side. This dual-path design, combining vertical and radial paths, significantly enhances airflow and debris removal efficiency, effectively preventing localized blockages and heat accumulation, thereby delaying performance degradation of the polishing pad 102 and extending its service life.

[0026] The hollow structure of the outer wall of the mounting groove 105 is a plurality of second through holes 110 evenly distributed along the circumferential direction. The second through holes 110 connect the inside and outside of the mounting groove 105. Each second through hole 110 is an elongated hole, and the length direction of each second through hole 110 is parallel to the axial direction of the base 101.

[0027] In this embodiment, by providing an elongated second through hole 110 parallel to the axial direction of the base 101 on the outer wall of the mounting groove 105, a radial heat dissipation channel evenly distributed along the circumference is formed. The second through hole 110 not only significantly increases the side ventilation area, but also utilizes the airflow direction generated during rotation to efficiently guide the heat and debris accumulated at the edge of the polishing pad 102 to dissipate rapidly into the external space, effectively preventing blockage and localized overheating in the edge area.

[0028] Secondly, the top of each of the reinforcing ribs 107 is flush with the inner bottom surface of the mounting groove 105. The polishing pad 102 is attached and fixed to the inner bottom surface of the mounting groove 105 and the top of the multiple reinforcing ribs 107 by an adhesive. The polishing pad 102 is made of porous polyurethane, porous rubber or porous polymer composite material containing fiber reinforcement.

[0029] In this embodiment, the top of the reinforcing rib 107 is flush with the bottom surface of the mounting groove 105, forming a stable and continuous support plane. This allows the polishing pad 102 to adhere evenly and firmly to the surface of the base 101 using adhesive, ensuring stability and reliability during high-speed polishing operations. Furthermore, the use of porous polyurethane, porous rubber, or fiber-reinforced porous polymer composite materials not only provides excellent breathability and elasticity but also enhances the material's durability and tear resistance. This allows the polishing pad 102 to withstand greater pressure and mechanical loads while maintaining efficient heat dissipation and chip removal performance, thereby significantly extending its service life.

[0030] Meanwhile, the thickness of the portion of the polishing pad 102 extending to the outside of the mounting groove 105 is 1 / 5 to 1 / 3 of the total thickness of the polishing pad 102.

[0031] In addition, each of the first through holes 109 has a first slot 111 on the side away from the mounting groove 105, and a first protective net 112 is provided at each of the first slots 111. Each of the second through holes 110 has a second slot 113 on the side away from the mounting groove 105, and a second protective net 114 is provided at each of the second slots 113. The first protective net 112 and the first slot 111, as well as the second protective net 114 and the second slot 113, are detachably snap-fit ​​connected.

[0032] In this embodiment, the first protective net 112 and the second protective net 114 can effectively block larger foreign objects from entering, preventing blockage of the internal channels, while maintaining normal airflow and debris discharge. The detachable snap-fit ​​connection method makes cleaning and replacement of the first protective net 112 and the second protective net 114 extremely convenient, allowing users to clean up accumulated debris or replace worn parts at any time.

[0033] Furthermore, the connecting protrusion 103 is a cylindrical or frustum-shaped structure, and the outer periphery of the connecting protrusion 103 is provided with multiple anti-slip ridges extending along the axial direction.

[0034] In this embodiment, the connecting protrusion 103 adopts a cylindrical or frustum-shaped structure to ensure the matching degree and centering with the rotating shaft interface of the polishing equipment.

[0035] The above-disclosed embodiments are merely one or more preferred embodiments of this application and should not be construed as limiting the scope of this application. Those skilled in the art can understand that implementing all or part of the above embodiments and making equivalent changes in accordance with the claims of this application still fall within the scope of this application.
