Description
本創作與夾頭有關,特別是指一種可提升防塵效果之夾頭。This creation is related to the chuck, especially a chuck that can improve the dustproof effect.
一般的夾頭主要包含有一個本體,本體具有一個軸孔與至少二條滑槽,其中的軸孔用來安裝一個傳動機構(如拉桿),至於各個滑槽則是用來安裝一個夾具。藉此,夾具可受傳動機構的傳動而沿著滑槽往復移動,用以夾持待加工工件。A general chuck mainly includes a body. The body has a shaft hole and at least two sliding grooves. The shaft hole is used to install a transmission mechanism (such as a pull rod), and each sliding groove is used to install a clamp. Thereby, the clamp can be driven by the transmission mechanism to move back and forth along the sliding groove to clamp the workpiece to be processed.
然而,工件在加工過程中會產生許多切削屑,這些切削屑很容易隨著切削液流入滑槽內並堆積在裡面慢慢生鏽,造成夾具與滑槽之間的摩擦力變大,如此一來,夾具於滑槽內移動時會受到摩擦力的影響而產生夾持力降低,亦可能會導致夾具的結構損壞。However, a lot of cutting chips will be generated during the processing of the workpiece. These cutting chips are easy to flow into the chute with the cutting fluid and accumulate in the chute slowly, causing the friction between the fixture and the chute to increase. In the future, when the clamp moves in the chute, it will be affected by friction, resulting in a reduction in the clamping force, which may also cause structural damage to the clamp.
為了解決切削屑的問題,請先參照圖1所示,目前的做法除了在軸孔處安裝一個防塵蓋2以外,另外在每個夾具1的前端安裝一個位於防塵蓋2上方之防塵板3,然後利用兩者之間的干涉配合來達到防塵效果。但是在實際操作中發現,夾具1在受到動力源的驅動之下對工件W進行夾持時,夾具1可能連同防塵板3一起發生上浮的情況(如圖1所示之假想線),導致防塵板3與防塵蓋2之間有間隙D產生,如此一來,工件W的切削屑便有機會經由此一間隙D跑到滑槽內,導致防塵效果下降。In order to solve the problem of cutting chips, please refer to Figure 1. The current practice is to install a
