藉由上述結構組成型態與技術特徵，本發明所揭線性導動構件A其實際應用上並不侷限裝設於何種裝置結構上，例如第1至6圖所揭目標物05為精密滑台，而第7、8圖所揭目標物05B則為夾爪；本發明線性導動構件A結構型態設計上，主要藉由該二線性軌道30係呈構件彼此獨立分別裝設狀態分設於螺帽導動座20二導動側壁22相對位置處之分離式型態特徵，以捨棄習知ㄩ字形軌道座部位，令線性導動構件A所需設置厚度大幅縮減(註：縮減幅度依產品規格大小而有所不同)，如此一來可更利於相關產品的輕量化與小型化設計；另一方面，本發明所揭各線性軌道30分別透過可調整抵靠部31與鎖固定位構件32各自調整定位之型態特徵，俾可讓線性軌道30之安裝與調整更加靈活，而能因應不同業者之裝設組立需求。 With the above-mentioned structural composition and technical features, the linear guide member A disclosed in the present invention is not limited to what device structure is installed in the practical application. For example, the object 05 disclosed in Figures 1 to 6 is a precision slide. The object 05B disclosed in Figures 7 and 8 is a jaw; in the structural design of the linear guide member A of the present invention, the two linear rails 30 are mainly arranged separately from each other. The separate type feature of the two guiding side walls 22 of the nut guide base 20 is to discard the conventional U-shaped rail seat portion, so that the required thickness of the linear guiding member A is greatly reduced (Note: the reduction range is The size and size of the product are different. In this way, the lightweight and miniaturized design of the related products can be more favorable; on the other hand, the linear rails 30 of the present invention respectively pass through the adjustable abutting portion 31 and the lock fixing member. Each of the 32 types of positioning features can be adjusted to make the installation and adjustment of the linear track 30 more flexible, and can meet the needs of different manufacturers.
如第7圖所示，本例中，所述鎖固定位構件32B，係於該線性軌道30B的二端向對應處分別裝設有一鎖迫塊326，各該鎖迫塊326係藉由複數根定位螺栓327之鎖固加以定位，藉由各該鎖迫塊326抵迫於該線性軌道30B的端向壁，以使該線性軌道30B調整確定後的狀態獲得定位。此外，本例中亦揭示供該線性軌道30B抵靠裝設之目標物05B係為一夾爪結構，以使其滾珠螺桿10B結構上設有間隔配置的二螺帽導動座20B可沿著該滾珠螺桿10B作相對開合位移運動，且該二螺帽導動座20B於圖中之頂側分別凸設有一夾持部23。 As shown in FIG. 7, in the present embodiment, the lock fixing member 32B is respectively provided with a locking block 326 at the two ends of the linear rail 30B, and each of the locking blocks 326 is composed of a plurality of locking blocks 326. The locking of the root positioning bolt 327 is positioned, and each of the locking blocks 326 is pressed against the end wall of the linear rail 30B to adjust the determined state of the linear rail 30B to obtain the positioning. In addition, in this example, it is also disclosed that the target object 05B for the linear track 30B is a jaw structure, so that the ball screw 10B is provided with a spacer arrangement of the second nut guide seat 20B along the ball screw 10B. The ball screw 10B is moved relative to the opening and closing movement, and the two nut guides 20B are respectively provided with a clamping portion 23 on the top side of the figure.
如第9圖所示，本例中，該螺帽導動座20的二導動側壁22相對位置處，於該二線性軌道30的上方間隔位置處更裝設有二附加線性軌道50，所述二附加線性軌道50係供裝設一滑動件60，令該滑動件60係以該螺帽導動座20為承載座進行滑動；本例之型態設計，係可使單一螺帽導動座螺帽共用多個滑軌而能產生附加功能，從而達到滿足多元使用需求之優點與實用進步性，此外本例中所提到的滑動件60，可為另外透過其它驅動源加以單獨驅動之型態，亦即該滑動件60僅是以該螺帽導動座20為承載座而具有一導動介面，但該滑動件60的驅動可以是另外單獨控制的狀態。As shown in FIG. 9 , in the present example, the two guide rails 22 of the nut guide seat 20 are oppositely disposed at two positions, and two additional linear rails 50 are further disposed at intervals above the two linear rails 30. The additional linear track 50 is provided with a sliding member 60 for sliding the sliding member 60 as a bearing seat; the design of the present embodiment enables a single nut to be guided. The seat nut shares a plurality of slide rails to create additional functions, thereby achieving the advantages and practical advancement of meeting multiple use requirements. In addition, the slide member 60 mentioned in this example can be separately driven by other drive sources. The type, that is, the slider 60 has only a guiding interface with the nut guide 20 as a carrier, but the driving of the slider 60 can be separately controlled.
如第10圖所示，本例中，該螺帽導動座20於該二導動側壁22的相異側，係更裝設有間隔相對配置的二附加線性軌道50B，所述二附加線性軌道50B供裝設一滑動件60B，令該滑動件60B係以該螺帽導動座20為承載座進行滑動；針對本例實施型態須說明的一點是：因為該滑動件60B用以供二附加線性軌道50B裝設的二支架部61會呈交錯向延伸跨越其中一側線性軌道30，所以該二附加線性軌道50B的設置長度須小於該線性軌道30的設置長度，以免影響該線性軌道30兩端的裝設定位結構；本例實施型態係提供一種多線軌共構整合型態，以滿足相關業界之多元化線性導動功能需求。As shown in FIG. 10, in this example, the nut guide seat 20 is disposed on the opposite side of the two guiding side walls 22, and is further provided with two additional linear orbits 50B spaced apart from each other. The rail 50B is provided with a sliding member 60B, so that the sliding member 60B is slid with the nut guiding seat 20 as a bearing seat; for the embodiment of the present invention, it should be noted that the sliding member 60B is used for The two bracket portions 61 of the additional linear track 50B are arranged to extend across the one side of the linear track 30 in a staggered manner, so the set length of the two additional linear tracks 50B must be smaller than the set length of the linear track 30 so as not to affect the linear track. The configuration of the set position at both ends of the 30; the embodiment of this example provides a multi-track rail co-conformity integration type to meet the diversified linear steering function requirements of the relevant industry.
