Description
本新型係關於機床軸承鎖緊元件,特別是指一種用於拆裝鎖緊螺帽的工具。 The present invention relates to a machine tool bearing locking element, and more particularly to a tool for disassembling a locking nut.
鎖緊螺帽是機械常用的緊固元件,廣泛用於各機器設備中零件的連接和定位。如圖1所示,鎖緊螺帽10的周側具有等間隔設置的凹槽11,用以配合如圖2所示的C形扳手20進行拆裝作業,其操作方式是將C形扳手20的兩個卡爪21容置卡勾在該C形扳手20的二相對應的凹槽11內,藉此旋轉C形扳手20而帶動該鎖緊螺帽10轉動。 The lock nut is a commonly used fastening component for machinery and is widely used for the connection and positioning of parts in various machines. As shown in FIG. 1 , the circumferential side of the locking nut 10 has equally spaced grooves 11 for engaging and disassembling the C-wrench 20 as shown in FIG. 2 , and the operation mode is to use the C-wrench 20 . The two claws 21 receive the hooks in the corresponding recesses 11 of the C-wrench 20, thereby rotating the C-wrench 20 to drive the lock nut 10 to rotate.
值得注意的是,當鎖緊螺帽10組裝處的周側空間有限時,C形扳手20的操作將顯得相當不順暢而困難;又,一支C形扳手20只能用於單一規格的鎖緊螺帽10,因此必須配備有多種規格的C形扳手20將增加組裝成本。此外,當鎖緊螺帽用於例如螺桿的軸承預壓組裝時,直接將鎖緊螺帽10鎖到最緊或使用量表測定鎖進距離,實際操作上並無法準確地掌握預壓軸承時所施予的力,因而容易導致鎖緊螺帽鎖附力過大使軸承擦增加而壽命降低,或者鎖附力過小造成進給軸的剛性不足、容易鬆脫等問題。 It is worth noting that when the circumferential side space of the assembly of the lock nut 10 is limited, the operation of the C-wrench 20 will appear rather unsmooth and difficult; in addition, a C-wrench 20 can only be used for a single-size lock. Tightening the nut 10, therefore having to be equipped with a variety of C-wrench 20 will increase assembly costs. In addition, when the lock nut is used for preload assembly of a bearing such as a screw, the lock nut 10 is directly locked to the tightest or the lock distance is measured by using a gauge, and the actual operation cannot accurately grasp the preload bearing. The force applied is therefore likely to cause the locking nut to be too strong to increase the bearing friction and the life is lowered, or the locking force is too small, resulting in insufficient rigidity of the feed shaft and easy loosening.
