Description
本發明係有關一種研磨工具機，尤指一種研磨工具機的擺動緩衝元件。 The invention relates to a grinding machine, in particular to a oscillating cushioning element of a grinding machine.
研磨工具機主要是透過高壓氣體或電力的驅動來研磨物體的表面。一般該研磨工具機包括有接收該高壓氣體或電力作為驅動力來源的驅動馬達，以及一連動於該驅動馬達的研磨盤。當欲進行研磨加工時，該研磨盤上貼附一層可替換的砂紙。該研磨盤受該驅動馬達驅動而以一研磨運行軌道高速擺動(oscillation)，透過該砂紙上的研磨顆粒與物體接觸而平整該接觸表面或者除去該表面的附著物。 The grinding machine is mainly used to grind the surface of an object by driving with high pressure gas or electricity. Generally, the abrasive machine includes a drive motor that receives the high-pressure gas or electric power as a source of driving force, and a grinding disc that is coupled to the drive motor. When grinding is to be performed, a layer of replaceable sandpaper is attached to the grinding disc. The grinding disc is driven by the drive motor to oscillate at a high speed in a grinding running track, and the abrasive particles on the sandpaper are in contact with the object to flatten the contact surface or remove the attachment of the surface.
該研磨盤進行高速擺動時，所產生的擺動力會透過該驅動馬達的驅動軸傳達到工具機本體上，操作者需額外施加力道來穩定該研磨工具機的運作。傳統研磨工具機上設有至少一分別連接工具機本體以及研磨盤的圓柱結構。如美國專利US8231437、US7056199、US3862520、US3815292、US3345784等，該研磨盤透過設置於該工具機本體四個角落的彈性柱體固定於該工具機本體上，設置於四個角落的彈性柱體，可為單一較粗的柱狀結構，或者可為多個彈性柱體的集合結構，如美國專利US6705931。另一方面，如美國專利US7771253、US6979254、US6855040、US5626510等，該研磨盤上設置有前後兩排的垂直柱體集合，每一排具有複數垂直彈性柱體。當該研磨盤進行擺動時，該些彈性柱體可以分攤該研磨盤所產生的擺動力而減少回饋給操作者的震動，使操作者更容易操作該研磨工具機。 When the grinding disc is oscillated at a high speed, the generated oscillating force is transmitted to the machine tool body through the driving shaft of the driving motor, and the operator needs to additionally apply a force to stabilize the operation of the grinding machine. The conventional grinding machine tool is provided with at least one cylindrical structure that connects the machine tool body and the grinding disc, respectively. The grinding disc is fixed to the machine tool body through an elastic cylinder disposed at four corners of the machine tool body, and is provided with elastic columns disposed at four corners, such as US Pat. No. 8,231,437, US Pat. No. 7,066, 199, US Pat. No. 3,862, 520, US Pat. It is a single thicker columnar structure, or may be a collection of a plurality of elastic cylinders, such as US Pat. No. 6,759,931. On the other hand, as shown in U.S. Patent No. 7,777,253, U.S. Patent No. 6,977, 254, U.S. Patent No. 6, 850, 050, U.S. Patent No. 5,265, 510, etc., the grinding disc is provided with a front and rear two rows of vertical columns, each row having a plurality of vertical elastic cylinders. When the grinding disc is oscillated, the elastic cylinders can share the oscillating force generated by the grinding disc to reduce the vibration feedback to the operator, making it easier for the operator to operate the grinding machine.
如圖1-1所示，以美國專利US7771253、US6979254、US6855040、US5626510等所揭示設置成平行一列的垂直彈性柱體11、11a為例，當該研磨工具機10開始運作時，如圖1-2，該研磨盤12受到一驅動馬達驅動而擺動，該些垂直彈性柱體11、11a會牽引該研磨盤12的位移，由於每一垂直彈性柱體11、11a為直線結構，且該些垂直彈性柱體11、11a的結構強度相等，實際上該研磨盤12擺動時朝向偏擺方向的垂直彈性柱體11的形變量會小於遠離偏擺方向的垂直彈性柱體11a的形變量，而導致該研磨盤12在運行時邊緣部分有一抬升高度R，也就是說該研磨盤12的運行軌道無法在同一平面上。甚者，該些垂直彈性柱體11、11a的形變位置主要在中央部分111。當該研磨工具機10長時間運作，最容易發生斷裂的位置是在該些垂直彈性柱體11、11a的中央部分111。由於每一垂直彈性柱體11、11a為個別獨立的直線結構，在該研磨工具機10運作時僅能依賴本身的結構強度來決定使用壽命。 As shown in FIG. 1-1, the vertical elastic cylinders 11, 11a arranged in parallel are disclosed as an example, as shown in US Pat. No. 7,777,253, US Pat. No. 6,977, 254, US Pat. 2, the grinding disc 12 is driven to swing by a driving motor, the vertical elastic cylinders 11, 11a will pull the displacement of the grinding disc 12, since each vertical elastic cylinder 11, 11a is a linear structure, and the vertical The structural strengths of the elastic cylinders 11 and 11a are equal. In fact, the shape of the vertical elastic cylinder 11 toward the yaw direction when the grinding disc 12 is swung is smaller than the deformation amount of the vertical elastic cylinder 11a away from the yaw direction, resulting in The grinding disc 12 has a lifting height R at the edge portion during operation, that is to say, the running track of the grinding disc 12 cannot be in the same plane. Moreover, the deformation positions of the vertical elastic cylinders 11, 11a are mainly at the central portion 111. When the abrasive power tool 10 is operated for a long time, the most prone to breakage is at the central portion 111 of the vertical elastic cylinders 11, 11a. Since each vertical elastic cylinder 11, 11a is an individual independent linear structure, the grinding machine 10 can only depend on its own structural strength to determine the service life.
本發明之主要目的，在於解決傳統研磨工具機運作時，其研磨盤擺動至邊緣時無法與接觸物體貼合，且連接工具機本體與研磨盤的垂直彈性柱體容易從中央部分斷裂，無法長時間連續使用的問題。 The main purpose of the invention is to solve the problem that the conventional grinding machine can not be attached to the contact object when the grinding disc is swung to the edge, and the vertical elastic cylinder connecting the machine tool body and the grinding disc is easily broken from the central portion, and cannot be long. The problem of continuous use of time.

In another embodiment, the first connecting ends 431 of each of the buffer portions 43 are separated from each other, and the second connecting ends 432 of the buffer portions 43 are separated from each other, as shown in FIG. 5, so that the swinging is performed. Each of the buffer portions 43 of the cushioning member 40 is disposed separately.
就該擺動緩衝元件40上複數該緩衝部43的排列而言，於一實施例中，請參『圖3』所示，該擺動緩衝元件40包含有複數以一對稱軸X2結構鏡像對應的彈性緩衝段433。或者，請參『圖6』所示，該擺動緩衝元件40包含有複數組分別以複數對稱軸X2結構鏡像對應的一第一彈性緩衝段433a與一第二彈性緩衝段433b。 For the arrangement of the plurality of buffer portions 43 on the swing buffer member 40, in an embodiment, as shown in FIG. 3, the swing buffer member 40 includes a plurality of elastic images corresponding to a mirror image of the axis of symmetry X2. Buffer section 433. Alternatively, as shown in FIG. 6 , the wobble buffer component 40 includes a first elastic buffer segment 433 a and a second elastic buffer segment 433 b corresponding to the complex array of mirror images X 2 .
在研磨工具機運作的過程中，該擺動緩衝元件40下半部的形變量往往大於上半部的形變量，為了能提升本發明擺動緩衝元件40的結構強度，請參『圖7』所示，該第一連接端431的寬度W1小於該彈性緩衝段433的寬度，該彈性緩衝段433的寬度W2小於該第二連接端432的寬度W3。甚者，該彈性緩衝段433的寬度沿著該第一連接端431至該第二連接端432的方向增加。另一方面，該擺動緩衝元件40的外側緩衝部43a的寬度大於中央緩衝部43b的寬度。 During the operation of the grinding machine tool, the shape of the lower half of the swinging cushioning member 40 is often larger than the shape of the upper half. In order to improve the structural strength of the swinging cushioning member 40 of the present invention, please refer to FIG. 7 The width W1 of the first connecting end 431 is smaller than the width of the elastic buffering section 433, and the width W2 of the elastic buffering section 433 is smaller than the width W3 of the second connecting end 432. Moreover, the width of the elastic buffer segment 433 increases along the direction from the first connecting end 431 to the second connecting end 432. On the other hand, the width of the outer buffer portion 43a of the swing cushioning member 40 is larger than the width of the center buffer portion 43b.
本發明耐用研磨工具機的特點在於在一研磨工具機的本體與研磨盤之間設置有至少一擺動緩衝元件。該擺動緩衝元件具有一當該研磨工具機運作時產生形變的彈性緩衝段，該彈性緩衝段的結構呈現彎曲形狀。在進行形變時，可以提供較佳的延展性以穩定研磨盤的擺動， 使該研磨盤可以平穩的於同一平面上水平擺動，維持研磨的品質。在長時間運作時，因該彈性緩衝段具備有較長的形變區域，相較於傳統直線形的垂直彈性柱體，有效減少各局部結構所受的形變壓力，延長整體研磨工具機的使用壽命。 The durable abrasive working machine of the invention is characterized in that at least one oscillating cushioning element is arranged between the body of the grinding machine and the grinding disc. The oscillating cushioning member has an elastic buffering section that deforms when the abrasive power tool is in operation, and the structure of the elastic buffering section exhibits a curved shape. When deforming, better ductility can be provided to stabilize the oscillation of the grinding disc. The grinding disc can be horizontally oscillated smoothly on the same plane to maintain the quality of the grinding. In the long-term operation, because the elastic buffer section has a long deformation zone, compared with the conventional linear vertical elastic cylinder, the deformation pressure of each partial structure is effectively reduced, and the service life of the whole grinding machine tool is prolonged. .
