Description of the Invention: [Technical Field] The present invention provides a ball screw cooling device, in particular, the β-suitable structure of the present invention is simple, and the forced spoiler effectively removes the ball screw heat source Improves cooling and improves the life and accuracy of the ball mast. [Prior Art] According to the continuous development and improvement of the precision feed system, the linear transmission technology and its products have become the most important part of many precision machines, and various linear mechanism products have entered human life extensively. Within the processing plant and equipment, such as linear sliding, ball screw, etc.; although the development of linear mechanism technology is very rapid, consumer users still need continuous improvement of technology, so there are still many problems still to be developed. The related technology industries are also actively researching and developing various new creations and new inventions that can effectively improve the linear mechanism, especially on many high-precision and high-precision manufacturing machines that need to be stable and quiet (for example, wafer processing equipment). , CNC equipment, and so on), so at present, a number of technical blind spots in linear institutions are extremely urgent for research and development. In order to improve the impact of the ball screw in the case of high speed and high load, the cooling device will be installed on the screw and the nut to reduce the temperature of the ball screw. However, different designs have Its defects exist, and how to develop and improve more competitive products for cooling devices has become the focus of the industry. 5 200827087 A more conventional cooling device, such as Japanese Patent Laid-Open No. 63-1956, is provided with a cooling circulation path around the periphery of the nut, and a cooling path communicating with each other is also provided on the nut seat to make the cooling path of the two. The cooling circulation path is formed, such a cooling circulation path is rather cumbersome, and the cooling circulation path must be processed on the nut seat, which relatively increases the processing difficulty and cost, and the cooling liquid convection effect is not good, so the cooling is uneven, and Direct shadowing to the effect of cooling.
另如日本專利特開平11-333666則係於螺帽前後端 加裝冷卻裝置，該冷卻裝置是一種利用空氣對流產生擾 流，而達到冷卻之目的，但於螺帽兩端採空氣對流的方 法，其能帶走的熱源有效，直接影響到其冷卻效果，且其 無法深入螺帽内部，容易造成冷卻不均勻的現象，有進— 步改善之必要。 再者如日本專利特許3721264號者，其係在螺桿幸由、 螺帽及馬達座上均設有冷卻通道，並設計成循環之冷卻迴 路，透過冷卻液溫度調節裝置做為冷熱交換，而達到〆卻 的效果，但由於係採冷卻液來降溫，一旦密封結構失六文 將導致冷卻液外溢的現象，而造成環境污染的問題。 而刖述專利前案的共同問題在於：由於其無法有六文的 接近熱源，再加上其冷卻液的流動速度完全由冷名 X. f 1衣置的 輸出力來決定，故其流動速度較慢，且僅有冷卻液外周 處可供吸熱，因此其整體的冷卻效果不彰，散熱逮声也 ，再者部份現有設計的結構較為複雜，同時製造不户 6 200827087 而造成組配的不便，無形間提高其加工製造的成本。 換言之，現有的螺帽的冷卻結構因其冷卻液的流動速 度慢，且僅有外緣部份能吸熱，而影響到其降溫速度與效 果，因此如能使冷卻液的速度加快，且令冷卻液呈擾流 狀，則可增加其吸熱面積與速度，進一步即可提升其冷卻 效果，而本發明即用於達成此一目的。 【發明内容】 基於上述習知滾珠螺桿冷卻裝置之缺點，本發明人經 過研究改良後，終有確能達成以下發明目的之本發明誕 生。 即，本發明之主要目的在於，使冷卻液受擾流元件之 螺旋葉片的作用，而產生螺旋狀的流動前進，能強制擾流 使冷卻液充份吸收熱源，有效將滾珠螺桿熱源帶離，以提 升冷卻效果，進而提升滾珠螺桿之壽命與精度。 本發明之次要目的在於，提供一種結構簡化之螺帽螺 旋冷卻裝置，其能易於製造、且便於組裝，而能節省成本。 為達上述之發明目的，本發明係利用設有螺旋葉片之 擾流元件，裝設於螺桿與嫘帽冷卻流道中，其擾流元件之 目的，使冷卻液受擾流元件螺旋流道的作用，而產生螺旋 狀的流動前進，則可增加其吸熱面積充分的帶走熱源，進 一步即可提升其冷卻效果；另外值得一提的是冷卻裝置構 造簡單，不需複雜之配件搭配，主要利用螺桿與螺帽所剩 7 200827087 空間，以不影響螺桿與螺帽之強度為原則，來加工冷卻流 道；其上述擾流元件材質為撓性材質，開模時可旋轉脫 模，易於製造量產，且在一定規格内的冷卻流道時可共 用，具有相當的通用性，故本發明不但改善習知冷卻裝置 之缺點、且又添加了高通用性與易於製造量產之優點。 接下來舉一較佳實施例，並配合圖式及圖號，針對本 發明做進一步之說明，期能使貴審查委員對本發明有更 詳細的瞭解，惟以下所述者僅為用來解釋本發明之較佳實 施例，並非企圖據以對本發明做任何形式上之限制，是 以，凡是在本發明之創作精神下，而為本發明任何型式的 修飾或變更，皆仍應屬於本發明意圖保護之範疇。 【實施方式】 本發明第一實施例請參閱第一圖至第四圖所示，本發 明第一實施例，係於螺桿（5)中心部位加工一貫穿軸向 流道（5 1 )，如圖二所示，該軸向流道（5 1 )與螺桿 螺紋溝槽（5 2)之距離可設為最接近之距離，但要以不 影響螺桿（5)之鋼性為考量，如圖四所示，以利於冷卻 液充分吸收熱源；再者，於軸向流道（5 1 )内安裝一擾 流元件（8 0)其擾流元件（8 0)上設有螺旋葉片（8 0 1 )，其擾流元件（8 0 )係由撓性材質製成，如圖一 所示，於加工軸向流道（5 1 )不需刻意要求其裝配公差； 8 200827087 且安裝擾流元件（8 0)後的抽向流道（5 1 )，内部係 形成一螺旋狀流道’其螺旋狀流道主要目的能擾動冷卻 液，讓冷卻液可充分吸收熱源，並使其流動更為順暢，· 以上所述，即為本發明第一實施例各相關元件的相互 關係位置及其概述。 本發明第二實施例請參閱第一圖、第五圖及第四圖所 • 示，本發明之冷卻裝置也可應用於螺帽（1 〇)上，其冷 卻裝置應用於螺帽（i 0)的裝配方式為，係於螺帽（工 0 )端面加工數個軸向流道（^ 〇 2 )，其軸向流道（工 0 2)之排列方式主要環繞螺帽螺紋溝槽（丄〇 3 )排列， 如圖五所示，此排列方式主要使軸向流道（1 〇 2)能盡 里接近發熱源，使冷卻液可充分吸收熱源，加速散熱；另 外螺巾目（1 Q )冷卻裝置別於螺桿（5 )冷卻裝置之部分， Φ在於螺巾目（1 0 )徑向設有數個徑向迴流孔（1 〇 1 )如 ‘圖輯示，其徑向迴流孔（10 1)目的在於，係使相互 2行之軸向飢運（工〇 2 )形成一循環迴路；而後，將擾 肌70件（8 0 )裝設於轴向流道（1 0 2 )中，其擾流元 件（8 0)功用與優點第一實施例相同，在此不再多作贊 述； ' 在此必須說明本發明之冷卻褒置必要元件冷卻機（2 9 200827087 〇)，其與螺桿（5)、螺帽（1之壯 (2 0)為習知常見冷卻裝置 ：配關係’冷部機 (2〇1)與螺桿⑴、螺帽（1〇7"，其利用導流管 接合，形成一封二〇)之軸向流道（5 狀邴方4孫於 、于閉之冷卻迴路，其螺桿（5 ) 衣式係於’螺桿（5)之轴向流道（51)—端安裝 冷部液之輸入端（丨N)，相 n 輯螺杯（5)之軸向流道（5 二=卻液之輸出端(〇υτ);再者，螺帽 : 螺帽（1〇)之循環路徑之-端 女衣冷部液之輸入端（IN)，相對螺帽（1〇)之循環Another example is Japanese Patent Laid-Open No. 11-333666, which is equipped with a cooling device at the front and rear ends of the nut. The cooling device is a method for generating a convection by using air convection to achieve cooling, but adopting air convection at both ends of the nut. The heat source that can be taken away is effective, directly affecting its cooling effect, and it can not penetrate into the inside of the nut, which is likely to cause uneven cooling, and there is a need for further improvement. In addition, as in Japanese Patent No. 3721264, it is provided with a cooling passage on the screw, the nut and the motor seat, and is designed as a circulating cooling circuit, which is cooled and exchanged by the coolant temperature adjusting device. However, due to the cooling effect of the cooling liquid, if the sealing structure loses six words, the phenomenon of coolant overflow will occur, which will cause environmental pollution. The common problem with the patent case is that the flow rate of the cooling liquid is completely determined by the output force of the cold name X. f 1 because it cannot be close to the heat source of the six texts. It is slower and only has heat absorption at the outer periphery of the coolant. Therefore, the overall cooling effect is not good, and the heat dissipation is also heard. In addition, the structure of some existing designs is complicated, and the manufacturing is not complicated. Inconvenient, the invisible increases the cost of its manufacturing. In other words, the cooling structure of the existing nut is slow due to the slow flow rate of the coolant, and only the outer edge portion can absorb heat, which affects the speed and effect of the cooling, so that the speed of the coolant can be accelerated and the cooling can be performed. When the liquid is turbulent, the heat absorption area and speed can be increased, and the cooling effect can be further improved, and the present invention is used for achieving this purpose. SUMMARY OF THE INVENTION Based on the above-described drawbacks of the conventional ball screw cooling device, the inventors have succeeded in research and improvement, and it is finally possible to achieve the invention of the present invention. That is, the main object of the present invention is to cause the coolant to be subjected to the action of the spiral vanes of the spoiler element to generate a spiral flow forward, which can force the spoiler to fully absorb the heat source, thereby effectively removing the ball screw heat source. In order to improve the cooling effect, the life and accuracy of the ball screw can be improved. A secondary object of the present invention is to provide a nut runner cooling device which is simplified in structure, which can be easily manufactured and assembled, and can save cost. In order to achieve the above object, the present invention utilizes a spoiler element provided with a spiral blade, which is installed in a cooling passage of a screw and a cap, and the purpose of the spoiler element is to make the coolant flow through the spiral flow path of the spoiler element. When the spiral flow is advanced, the heat absorption area can be increased to take away the heat source, and the cooling effect can be further improved. In addition, it is worth mentioning that the cooling device has a simple structure and does not require complicated fittings, and mainly uses a screw. With the remaining 7200827087 space of the nut, the cooling flow channel is processed on the principle of not affecting the strength of the screw and the nut; the above-mentioned spoiler element is made of a flexible material, and can be rotated and demolded when the mold is opened, which is easy to manufacture and mass-produce. Moreover, it can be shared in a cooling flow passage within a certain specification, and has considerable versatility. Therefore, the present invention not only improves the disadvantages of the conventional cooling device, but also adds the advantages of high versatility and easy mass production. Next, a preferred embodiment will be described with reference to the drawings and the drawings, and the present invention will be further described, so that the reviewer can have a more detailed understanding of the present invention, but the following is only for explaining the present invention.
