Description
本發明係有關一種研磨件,尤指一種可有效散熱的研磨件。The invention relates to an abrasive member, in particular to an abrasive member which can effectively dissipate heat.
有鑑於目前研磨件在使用時會因高速旋轉而使得研磨片產生溫度過高的問題,各家廠商無不研發有降低研磨片溫度的技術。如中華民國專利公告號第M531405號專利案揭露了一種打磨轉接盤,該打磨轉接盤可受一電動驅動工具帶動旋轉以對一物體進行研磨。該打磨轉接盤包含有一盤體、一結合件、一軸承組件以及一帶動單元。該盤體具有複數逃氣孔,該結合件裝設於該盤體表面且具有複數分別與其中一該逃氣孔連通的通氣孔,該軸承組件裝設於該盤體且可帶動該盤體轉動,該帶動單元連接於該軸承組件與該電動驅動工具之間。當該打磨轉接盤於實際使用時,一研磨片可藉由一配合結合件而連接於該結合件,使得該研磨片在隨該盤體旋轉時可透過該些逃氣孔進行散熱。In view of the fact that the abrasive pieces are currently subjected to high-speed rotation during use, the temperature of the abrasive sheets is too high, and various manufacturers have developed techniques for lowering the temperature of the polishing sheets. For example, the Republic of China Patent Publication No. M531405 discloses a sanding adapter disk that can be rotated by an electric drive tool to grind an object. The sanding adapter disk comprises a disk body, a coupling member, a bearing assembly and a driving unit. The disk body has a plurality of air venting holes, and the coupling member is mounted on the surface of the disk body and has a plurality of vent holes respectively communicating with one of the air venting holes. The bearing assembly is mounted on the disk body and can drive the disk body to rotate. The driving unit is coupled between the bearing assembly and the electric drive tool. When the sanding adapter is in actual use, an abrasive sheet can be coupled to the joint by a mating joint such that the abrasive sheet can dissipate heat through the escape holes as the disc rotates.
然而,從上述M531405所揭可以發現,由於該結合件與該配合結合件之間是緊密結合(於一實施例中,該結合件與該配合結合件是由魔鬼氈的鉤狀結構及環狀結構所構成),故使得該研磨片受該配合結合件、該結合件以及該盤體覆蓋的表面將難以進行散熱,進而造成該研磨片會有溫度過高而不利使用的問題。However, it can be found from the above M531405 that since the coupling member and the mating coupling member are tightly coupled (in one embodiment, the coupling member and the mating coupling member are hook-shaped structures and loops of the devil felt). The structure is such that the surface of the polishing sheet that is covered by the mating joint, the joint, and the disc body is difficult to dissipate, thereby causing the problem that the abrasive sheet may be too hot to be used.
本發明之主要目的,在於解決習用實施中研磨片因表面受覆蓋而難以進行散熱的問題。The main object of the present invention is to solve the problem that the polishing sheet is difficult to dissipate due to the surface being covered by the conventional embodiment.
為達上述目的,本發明提供一種研磨件,選擇性裝配於一研磨手工具上,其包含有一研磨片以及一連接座。該連接座連接於該研磨片與該研磨手工具之間。其中,該研磨件具有一形成於該連接座與該研磨片之間且連通至外部的間隙,該連接座貫穿形成有複數與該間隙連通的導氣通孔,該些導氣通孔於該研磨件的旋轉過程中形成一得對該研磨片進行熱交換的氣流。To achieve the above object, the present invention provides an abrasive member selectively assembled to an abrasive hand tool comprising an abrasive sheet and a connector. The connector is coupled between the abrasive sheet and the abrasive hand tool. The abrasive member has a gap formed between the connecting seat and the polishing sheet and communicated to the outside. The connecting seat is formed with a plurality of air guiding through holes communicating with the gap, and the air guiding holes are formed therein. During the rotation of the abrasive member, a gas stream is formed which heat exchanges the abrasive sheet.
於一實施例中,該些導氣通孔環繞設置於該連接座。其中,該些導氣通孔設置於該連接座的外緣。進一步地,任二該導氣通孔之間的距離彼此相同。In an embodiment, the air guiding through holes are disposed around the connecting base. Wherein, the air guiding through holes are disposed at an outer edge of the connecting seat. Further, the distance between any of the air guiding through holes is the same as each other.
於一實施例中,該些導氣通孔的形狀均為圓形。In an embodiment, the air guiding through holes have a circular shape.
於一實施例中,該連接座具有一面對該間隙的凹面。In one embodiment, the connector has a concave surface for the gap.
於一實施例中,該研磨片具有一設置於該研磨片表面中央的第一裝配部,該連接座具有一設置於該連接座中央且供該第一裝配部組裝固定的第二裝配部。In one embodiment, the polishing sheet has a first fitting portion disposed at a center of the surface of the polishing sheet, and the connecting seat has a second fitting portion disposed at a center of the connecting seat and assembled and fixed by the first fitting portion.
本發明透過上述實施方式,相較於習用具有以下特點:Through the above embodiments, the present invention has the following characteristics as compared with the conventional ones:
本發明透過該研磨片與該連接座之間形成有該間隙以及該連接座具有與連通至該間隙連通的該些導氣通孔,使得該氣流會因該研磨件的旋轉而由該間隙流入以將該研磨件運作所產生的熱能帶出至該些導氣通孔外,藉此解決習用實施中研磨片因表面受覆蓋而難以進行散熱的問題。According to the present invention, the gap is formed between the polishing sheet and the connecting seat, and the connecting seat has the air guiding through holes communicating with the gap, so that the airflow flows in from the gap due to the rotation of the grinding member. The heat energy generated by the operation of the polishing member is carried out to the outside of the gas guiding holes, thereby solving the problem that the polishing sheet is difficult to dissipate due to the surface being covered by the conventional embodiment.

請參閱圖1至圖4,本發明提供一種研磨件1,該研磨件1可裝設於一研磨手工具2,使該研磨手工具2在驅動該研磨件1旋轉後得以對一物體(圖中未示出)表面進行研磨作業。該研磨件1包含有一研磨片11以及一連接座12,該研磨片11裝設於該連接座12一側,該研磨片11與該連接座12之間形成有一連通至外部的間隙13。具體來說,該研磨片11表面可具有研磨顆粒(例:金屬或石粒等),該連接座12可由彈性材質(例:橡膠)製成。其中,該連接座12貫穿形成有複數導氣通孔121,該些導氣通孔121分別與該間隙13連通。於一實施例中,該些導氣通孔121為環繞設置於該連接座12,如圖4所示,且任二該導氣通孔121之間的距離可彼此相同。若從該研磨片11與該連接座12的組裝結構觀之,該研磨片11具有一第一裝配部111,該連接座12具有一第二裝配部122,該第一裝配部111可裝設於該第二裝配部122以使該研磨片11固定於該連接座12一側,如圖3所示。於一實施例中,該第一裝配部111為一螺柱,該第二裝配部122為一供該螺柱(即,該第一裝配部111)螺合固定的螺孔;於另一實施例中,該第一裝配部111為複數扣片,該第二裝配部122為複數分別供其中一該扣片扣合的扣孔。Referring to FIG. 1 to FIG. 4, the present invention provides an abrasive member 1 which can be mounted on a grinding hand tool 2, so that the grinding hand tool 2 can be used to move an object after driving the polishing member 1. The surface is not subjected to a grinding operation. The polishing member 1 includes an abrasive sheet 11 and a connecting seat 12. The polishing sheet 11 is mounted on the side of the connecting seat 12, and a gap 13 is formed between the polishing sheet 11 and the connecting seat 12 to communicate with the outside. Specifically, the surface of the polishing sheet 11 may have abrasive particles (for example, metal or stone particles, etc.), and the connecting seat 12 may be made of an elastic material (for example, rubber). The connecting seat 12 is formed with a plurality of air guiding through holes 121 , and the air guiding through holes 121 are respectively connected to the gap 13 . In one embodiment, the air guiding through holes 121 are circumferentially disposed on the connecting base 12, as shown in FIG. 4, and the distance between any two of the air guiding through holes 121 may be the same as each other. The polishing sheet 11 has a first fitting portion 111 having a second fitting portion 122, and the first fitting portion 111 is mountable from the assembly structure of the polishing sheet 11 and the connecting seat 12. The second fitting portion 122 is configured to fix the polishing sheet 11 to the side of the connecting seat 12 as shown in FIG. In one embodiment, the first mounting portion 111 is a stud, and the second mounting portion 122 is a screw hole for the stud (ie, the first mounting portion 111) to be screwed and fixed; In the example, the first mounting portion 111 is a plurality of buckles, and the second mounting portion 122 is a plurality of fastening holes for fastening the one of the fastening pieces.
由上述技術說明可清楚了解該研磨件1的詳細組成,於此,本發明將進一步說明該研磨件1的使用過程及隨使用過程所產生的實施態樣。在該研磨件1的使用過程中,該連接座12連接於該研磨片11與該研磨手工具2之間,令該研磨手工具2得透過該連接座12而帶動該研磨片11轉動。於一實施例中,該連接座12具有一軸孔123,該研磨手工具2具有一傳動軸21,該傳動軸21可裝設於該軸孔123內,且該研磨手工具2可藉由氣動驅動方式或電動驅動方式來連動該傳動軸21帶動該研磨件1旋轉。當旋轉中的該研磨件1在接觸一物體表面(圖中未示出)以進行研磨作業時,由於該研磨片11與該連接座12之間形成有該間隙13以及該連接座12具有與該間隙13連通的該些導氣通孔121,故使得該些導氣通孔121在該研磨件1的旋轉過程中會形成有一氣流。其中,該氣流會因該研磨件1的旋轉而由該間隙13流入至該研磨片11與該連接座12之間,接著再從該研磨片11與該連接座12之間將該研磨件1運作所產生的熱能帶出至該些導氣通孔121外。此外,若該研磨片11因擠壓該物體表面而產生形變時,該氣流則會由該間隙13空間較小的一側朝該間隙13空間較大的一側流動而由部分該些導氣通孔121排出。據此,該研磨件1即可透過在該些導氣通孔121所產生的該氣流對該研磨片11進行熱交換動作以進行散熱,藉此解決習用實施中研磨片因表面受覆蓋而難以進行散熱的問題。The detailed composition of the abrasive member 1 can be clearly understood from the above technical description. Here, the present invention will further explain the use process of the abrasive member 1 and the embodiment produced by the use process. During the use of the abrasive member 1, the connecting seat 12 is connected between the polishing sheet 11 and the polishing hand tool 2, so that the polishing hand tool 2 can drive the polishing sheet 11 to rotate through the connecting seat 12. In one embodiment, the connecting seat 12 has a shaft hole 123. The grinding hand tool 2 has a driving shaft 21, and the driving shaft 21 can be installed in the shaft hole 123, and the grinding hand tool 2 can be pneumatically The driving mode or the electric driving mode interlocks the driving shaft 21 to drive the grinding member 1 to rotate. When the rotating grinding member 1 is in contact with an object surface (not shown) for performing a grinding operation, the gap 13 is formed between the polishing sheet 11 and the connecting seat 12, and the connecting seat 12 has a The air guiding holes 121 communicate with the gaps 13 such that the air guiding holes 121 form an air flow during the rotation of the grinding member 1. The airflow flows from the gap 13 between the polishing sheet 11 and the connecting seat 12 due to the rotation of the polishing member 1, and then the abrasive member 1 is further separated from the polishing sheet 11 and the connecting seat 12. The heat generated by the operation is carried out to the outside of the gas guiding holes 121. In addition, if the polishing sheet 11 is deformed by pressing the surface of the object, the air flow flows from the side where the space of the gap 13 is small toward the side where the space of the gap 13 is large, and some of the air is guided by the air. The through hole 121 is discharged. Accordingly, the polishing member 1 can perform heat exchange operation on the polishing sheet 11 through the air flow generated by the gas guiding holes 121 to dissipate heat, thereby solving the problem that the polishing sheet is difficult to be covered by the surface in the conventional practice. The problem of heat dissipation.
承上,為了使該研磨件1在旋轉時能夠具有更好的散熱效果,於一實施例中,如圖4所示,該些導氣通孔121的形狀均為圓形,以令該氣流得將熱能而順暢地由該些導氣通孔121排出。此外,該些導氣通孔121可設置於該連接座12的邊緣(意即,該些導氣通孔121為設置於該連接座12的近外側處),使得該氣流在由該間隙13進入該研磨片11與該連接座12之間後能快速地流至該些導氣通孔121以排出熱能。除了前述二實施例之外,該連接座12具有一面對該間隙13的凹面124,如圖3所示,該凹面124會延長該研磨片11與該連接座12之間的該間隙13,藉此加大該氣流的散熱空間。In order to enable the polishing member 1 to have a better heat dissipation effect when rotating, in an embodiment, as shown in FIG. 4, the air guiding holes 121 have a circular shape to make the airflow. Heat energy is smoothly discharged from the gas guiding holes 121. In addition, the air guiding through holes 121 may be disposed at the edge of the connecting seat 12 (that is, the air guiding through holes 121 are disposed at the outer side of the connecting seat 12), so that the air flow is in the gap 13 After entering between the polishing sheet 11 and the connecting seat 12, the air can be quickly flowed to the air guiding holes 121 to discharge heat energy. In addition to the foregoing two embodiments, the connector 12 has a concave surface 124 opposite to the gap 13, as shown in FIG. 3, the concave surface 124 extends the gap 13 between the abrasive sheet 11 and the connector 12, Thereby increasing the heat dissipation space of the airflow.
以上已將本發明做一詳細說明,惟以上所述者,僅爲本發明之一較佳實施例而已,當不能以此限定本發明實施之範圍,即凡依本發明申請專利範圍所作之均等變化與修飾,皆應仍屬本發明之專利涵蓋範圍內。The present invention has been described in detail above, but the foregoing is only a preferred embodiment of the present invention, and is not intended to limit the scope of the present invention. Variations and modifications are still within the scope of the patents of the present invention.
