Description
本創作與加工機有關,特別是有關於一種加工機之工件輔助夾持機構。This creation is related to the processing machine, in particular to the workpiece-assisted clamping mechanism of a processing machine.
一般在使用加工母機(例如車床或磨床)對長條型工件進行加工之前,必須另藉由一輔助之夾持機構將待加工工件之另端夾持固定住,以確保長條型工件在加工過程中具有足夠的穩定性,使工件能夠獲得良好的加工精度,此種工件之加工需求特別於磨床之精密加工更顯重要。Generally, before processing a long-length workpiece using a machining machine (such as a lathe or a grinder), the other end of the workpiece to be processed must be clamped and fixed by an auxiliary clamping mechanism to ensure that the long-shaped workpiece is processed. The process has sufficient stability to enable the workpiece to achieve good machining accuracy. The machining requirements of such workpieces are especially important for the precision machining of the grinding machine.
傳統的輔助夾持機構主要包含有一中心架,中心架具有供工件穿設之一中心孔,並於中心孔之周圍設置有至少三組夾座,各夾座能受到一調整螺栓之驅動而沿著中心孔之徑向相對工件靠近或遠離,用以夾持或釋放工件。然而在此習用設計中,各夾座係以調整螺栓螺合穿設於中心架之肉身螺孔中,所以只要有其中一組夾座因長期使用受到工件轉動之長期晃動反饋力量,將導致中心架之螺牙累積磨損,造成螺栓進給間隙變大影響工件之加工精度,且一旦螺牙累積磨損過大不堪使用時,此時無法僅維修單一夾座,通常需三夾座連同中心架整個一起更換,如此將會造成整組夾持機構之購置成本不符經濟效益。此外,上述輔助夾持機構之各夾座之調整螺栓僅能在中心架之螺孔內進行位移行程調整,因此調整螺栓可位移之距離為螺栓長度減掉中心架螺孔之長度,換言之,一旦待加工工件的 尺寸過大或過小時,前述各夾座所能提供的夾持伸縮距離就會受到不當限制而無法使用,此時除非更換另組不同尺寸之輔助夾持機構,否則將無法續行後續加工作業,如此不單會增加輔助夾持機構之拆換作業成本且需耗資成本囤積多個不同尺寸之輔助夾持機構。The conventional auxiliary clamping mechanism mainly comprises a center frame, the center frame has a central hole for the workpiece to be pierced, and at least three sets of clamping seats are arranged around the central hole, and each clamping seat can be driven by an adjusting bolt. The center hole is radially adjacent to or away from the workpiece for holding or releasing the workpiece. However, in this conventional design, each of the clamps is screwed into the screw hole of the body of the center frame by the adjusting bolt, so that as long as one of the clamps is subjected to the long-term swaying feedback force of the workpiece due to long-term use, the center will be caused. Accumulated wear of the screw of the frame causes the screw feed gap to become large, which affects the machining accuracy of the workpiece. Once the cumulative wear of the screw is too large, it is impossible to repair only a single holder at this time. Usually, the three clamps together with the central frame are required. Replacement, this will result in the acquisition cost of the entire group of clamping mechanisms is not economical. In addition, the adjusting bolts of the clamps of the auxiliary clamping mechanism can only adjust the displacement stroke in the screw holes of the center frame, so the distance that the adjusting bolt can be displaced is the length of the bolt minus the length of the screw hole of the center frame, in other words, once Workpiece to be machined If the size is too large or too small, the clamping and telescopic distance that each of the above-mentioned holders can provide will be improperly restricted and cannot be used. In this case, the subsequent processing operations cannot be continued unless another set of auxiliary clamping mechanisms of different sizes are replaced. This will not only increase the cost of the replacement work of the auxiliary clamping mechanism, but also cost a lot of auxiliary clamping mechanisms of different sizes.

若待加工工件42的尺寸有所改變時,如第4及6圖所示,必須先拆下各固定件35以解除夾座33與調整塊34之間的連接關係,使夾座33完全與滑座32分離,此時的調整塊34會藉由與第二滑槽323之間的T形斷面配合而保持在第二滑槽323內,接著將夾座33的位置直接移動到能夠抵住工件42表面之後再藉由本身之第二齒部332與滑座32之第一齒部322形成咬合,之後再將各固定件35鎖設於適當位置的穿孔336及固定孔346,使夾座33與調整塊34再度連接在一起,此時可以視實際狀況藉由調整塊34於第二滑槽323內之移動而調整夾座33的位置,用以對夾座33位置進行第一段微調之後再鎖緊各固定件35,接著再藉由轉動微調螺栓36對夾座33的位置進行第二段的微調,使夾座33確實緊抵住工件42表面,最後將定位螺栓37鎖緊之後即完成夾座33的定位。If the size of the workpiece 42 to be processed is changed, as shown in Figures 4 and 6, the fixing members 35 must be removed first to release the connection relationship between the holder 33 and the adjusting block 34, so that the holder 33 is completely The slider 32 is separated, and the adjusting block 34 is held in the second sliding slot 323 by the T-shaped cross-section between the second sliding slot 323, and then the position of the clamping seat 33 is directly moved to the position After the surface of the workpiece 42 is engaged, the second tooth portion 332 of the workpiece 42 is engaged with the first tooth portion 322 of the sliding seat 32, and then the fixing member 35 is locked in the appropriate position of the through hole 336 and the fixing hole 346 to make the clip. The seat 33 and the adjusting block 34 are connected again. At this time, the position of the clamping seat 33 can be adjusted by the movement of the adjusting block 34 in the second sliding slot 323 according to the actual situation, and the first segment of the clamping seat 33 can be positioned. After the fine adjustment, the fixing members 35 are locked, and then the second stage is finely adjusted by rotating the fine adjustment bolts 36, so that the clamping seat 33 is surely pressed against the surface of the workpiece 42, and finally the positioning bolts 37 are locked. The positioning of the holder 33 is then completed.
綜上所陳,本創作之工件輔助夾持機構10所提 供的夾具30可以藉由各固定件35鎖固在夾座33之不同穿孔336內,並且配合調整塊34於第二滑槽323內之移動,使夾座33之移動距離可以多段式的調整而對不同尺寸的工件40、42都能夠穩定地進行夾持,用以提供良好的加工穩定性及加工精度,同時也就不需要製作不同尺寸的工件輔助夾持機構10,以節省製造成本。另一方面,若其中一組或多組夾具30因長期使用受到工件40、42轉動之長期晃動反饋力量而發生損壞時,使用者可以輕易地將損壞的夾具30從中心架20上拆卸下來,以便進行部分零件的更換或維修,並不需要連同中心架20一起更換,用以提升維修便利性及有效降低維修成本。In summary, the workpiece assisted by the clamping mechanism 10 of the present invention The clamps 30 can be locked in the different through holes 336 of the clamping seat 33 by the fixing members 35, and the movement of the adjusting block 34 in the second sliding slot 323 can be adjusted, so that the moving distance of the clamping seat 33 can be adjusted in multiple stages. The workpieces 40 and 42 of different sizes can be stably clamped to provide good processing stability and processing precision, and at the same time, it is not necessary to manufacture workpiece auxiliary clamping mechanisms 10 of different sizes to save manufacturing costs. On the other hand, if one or more sets of jigs 30 are damaged by long-term use of the long-term sway feedback force of the rotation of the workpieces 40, 42, the user can easily detach the damaged jig 30 from the center frame 20, In order to replace or repair parts, it is not necessary to replace them with the center frame 20 to improve maintenance convenience and reduce maintenance costs.
