Description
本發明係涉及一種分度裝置;特別是指一種滾子轉座連動齒盤形式之創新分度裝置結構型態揭示者。The present invention relates to an indexing device; in particular, it refers to the disclosure of the structural type of an innovative indexing device in the form of a roller swivel seat linked with a toothed disc.
本發明所指分度裝置,業界亦稱之為分度盤,是目前機器加工上被應用相當廣泛的裝置,因為一般三軸加工機器並無法滿足旋轉角度加工之需求,而分度盤即為補足三軸加工機器之不足所發展出來的產品,能夠將機器加工效能發揮到最大。The indexing device referred to in the present invention, also known as the indexing plate in the industry, is a device that is widely used in machine processing at present, because the general three-axis processing machine cannot meet the requirements of rotation angle processing, and the indexing plate is The products developed to make up for the shortage of three-axis processing machines can maximize the processing efficiency of the machine.
目前分度裝置的驅動型態主要分為蝸桿連動齒輪以及蝸桿連動滾子轉座兩種型態,若就傳動效率、耐久性及傳動背隙等面向而論,其中蝸桿連動滾子轉座型態表現相對較佳,尤其傳動背隙方面,幾乎能夠達到零背隙狀態,這也是其適用於高精度加工的原因之一。At present, the driving types of indexing devices are mainly divided into two types: worm-linked gear and worm-linked roller seat. In terms of transmission efficiency, durability and transmission backlash, the worm-linked roller seat type The state performance is relatively good, especially in the transmission backlash, which can almost reach the zero backlash state, which is one of the reasons why it is suitable for high-precision machining.
然而,蝸桿連動滾子轉座型態的習知分度裝置,於其實際應用經驗中仍舊有其未臻完善之處;概因,隨著相關業界對於加工精度的要求提高,習知分度裝置縱使採用蝸桿連動滾子轉座型態,亦可能無法達到要求,因蝸桿連動滾子轉座型態之分度定位精度約僅能達到20秒(角度單位),所以當業界之加工精度要求更高時,即不符合其需求,而目前面臨此種超高加工精度需求時,相關業界雖嘗試採用角度編碼器,以期達到加工要求,但此種作法因角度編碼器頗為昂貴,因此對於需要採用的業者而言,往往基於不符合較佳產業經濟效益而卻步;況且,加工最終結果是否如預期,分度裝置的轉盤定位狀態是否緊實牢固,也是重要原因之一。However, the conventional indexing device in the form of a worm-driven roller swivel seat still has some imperfections in its practical application experience; probably because, as the requirements of the related industries for machining accuracy increase, the conventional indexing device Even if the device adopts the worm-linked roller swivel type, it may not be able to meet the requirements, because the indexing and positioning accuracy of the worm-linked roller swivel type can only reach about 20 seconds (angle unit), so it meets the processing accuracy requirements of the industry When it is higher, it does not meet its needs. At present, when faced with such ultra-high processing precision requirements, the relevant industries try to use angle encoders in order to meet the processing requirements, but this method is quite expensive because of angle encoders, so for Those who need to adopt it are often discouraged because they do not meet the best industrial economic benefits; moreover, whether the final result of processing is as expected, and whether the positioning state of the turntable of the indexing device is tight and firm are also one of the important reasons.
是以,針對上述習知分度裝置所存在之問題點,如何研發出一種製造組裝成本相對降低,且定位狀態更加緊固而更具理想實用性之創新構造,實有待相關業界再加以思索突破之目標及方向者;有鑑於此,發明人本於多年從事相關產品之製造開發與設計經驗,針對上述之目標,詳加設計與審慎評估後,終得一確具實用性之本發明。Therefore, in view of the problems existing in the above-mentioned conventional indexing devices, how to develop an innovative structure with relatively lower manufacturing and assembly costs, a firmer positioning state and more ideal practicability, really needs further thinking and breakthroughs in the relevant industries. In view of this, the inventor has been engaged in the manufacturing, development and design of related products for many years. After careful design and careful evaluation for the above-mentioned goals, he finally obtained a practical invention.

如圖4及圖5所示,本例中,該活塞式齒盤53係更裝配有複數止密環襯531以與該環凹槽341之間達成滑動式密合關係,又該活塞式齒盤53與該環凹槽341之Y軸向相對應側之間形成有一流體容置部532,用以導入一流體60產生壓力驅使該活塞式齒盤53朝該嚙合位置作動(如圖6之箭號L1所示),又該活塞式齒盤53與該固定齒盤51之間裝配有複數彈力復位件70 (註:可為但不限於採用螺旋彈簧),該複數彈力復位件70於該活塞式齒盤53處於該嚙合位置時如圖6所示,係被壓縮而蓄積彈力,而當所述流體60產生之壓力解除時如圖5所示,能利用該複數彈力復位件70之彈力釋放(如圖5之箭號L2所示),從而驅使該活塞式齒盤53回復至該釋放位置。其中,該流體60為氣體或油液任其中一者。本例僅為該活塞式齒盤53能夠達成往復運動的較佳實施例,但就目前習知技術可見的驅動形式,相關業界當然能夠輕易瞭解其他等效的驅動方式亦可達成,例如令該活塞式齒盤53的往復動作均採用流體壓力來推動,也是可行的一種驅動方式,也應該包含於本發明的主要界定範圍內,即不一一詳述。

藉由上述結構組成型態與技術特徵,本發明所揭滾子轉座連動齒盤式分度裝置實際應用上,首先是透過驅動蝸桿20之轉動來帶動滾子轉座30產生順向或逆向旋轉,由於驅動蝸桿20與滾子轉座30之間相較於蝸桿帶動齒輪式型態而言,具有較佳的傳動緊密度,兩者之間能夠達到零背隙(Zero backlash)傳動狀態,故單就此優異特性,已經能夠讓分度裝置的定位精度達到約20秒,而本發明進一步整合該定位齒盤組50的用意,其作動上,當滾子轉座30轉動至預定角度位置時,活塞式齒盤53就會受控制位移至嚙合位置如圖6所示,此時活塞式齒盤53會同時與固定齒盤51、轉動齒盤52相嚙合,此過程中,因為固定齒盤51的齒面角度分佈精準度可高達5秒,且活塞式齒盤53與固定齒盤51、轉動齒盤52之間的嚙合為梯形齒配合型態,具有入齒時自動導引正位作用,所以當活塞式齒盤53與固定齒盤51相嚙合時,若活塞式齒盤53角度有偏差就會被導引正位,而因為活塞式齒盤53也同時與轉動齒盤52相嚙合,所以轉動齒盤52(連同滾子轉座30)角度若有偏差,也就會一併被導引正位(如圖7至圖9之變化所示),也就是說,本發明所揭滾子轉座連動齒盤式分度裝置實際應用上,其分度定位狀態之精準度可高達5秒;除此之外,本發明採用定位齒盤組50的另一優點,是工件鎖附盤33處於定位狀態時,能夠具備更高的定位鎖緊力,從而有效防止工件於加工過程中產生位移;再就製造組裝成本面向而論,雖然前文所提習知採用角度編碼器的方式也能達到高精度要求,但本發明採用定位齒盤組50的成本與習知採用角度編碼器的成本相較,本發明至少能夠降低設置成本約7至10倍之多,此經濟效益之顯著提升結果,顯非習知技術所能匹比;是以,本發明所揭滾子轉座連動齒盤式分度裝置確實能夠為相關技術領域帶來一大躍進。With the above-mentioned structural composition and technical features, in the actual application of the roller turret linked toothed disc indexing device disclosed in the present invention, firstly, the rotation of the driving
