Description
本發明係有關於一種數位扭力扳手,特別是指一種在握把上任一點施力均能讀取出相同扭力值的數位扭力扳手結構及使其均力之方法。The invention relates to a digital torque wrench, in particular to a digital torque wrench structure capable of reading the same torque value at any point on the grip and a method for equalizing the force.
按,起子、套筒、扳手...等等手工具廣泛使用於機械組配或維修之場合中,對於機械或零件上之每一個螺鎖元件,例如:螺絲或螺栓,進行鎖合或拆卸之操作,然而,在某些高精密機械中,各個螺鎖元件卸除有一定的程序及適當扭力操作需求,如果操作不慎可能會造成螺鎖元件或螺孔崩牙損壞或損及機械本身之操作功能及精密度,但習知之手工具並無法於施力操作時具有偵測及顯示扭力功能,因此,無法讓使用者可以瞭解實際的施力扭力值,而必需憑經驗操作手工具,而可能產生人為扭力操作不當之問題。Press, screwdrivers, sleeves, wrenches, etc. are widely used in mechanical assembly or maintenance, for each screw-on component of a machine or part, such as screws or bolts, to be locked or disassembled. Operation, however, in some high-precision machines, each screw-locking component has a certain procedure and proper torque operation requirements. If the operation is inadvertent, the screw-locking component or the screw hole may be damaged or damage the machine itself. The operation function and precision, but the conventional hand tool can not detect and display the torque function when the force is applied. Therefore, the user cannot understand the actual torque value, and the hand tool must be operated by experience. There may be problems with improper manipulation of human torque.
另外,如考慮以各別手工具需求予以分別結合扭力偵測器,以設計與製造不同的扭力偵測手工具,則必需耗費更多的設計、製造成本,並且,不適用於所有的手工具操作場合,而不利於實際應用操作,無法提供給產業直接利用。In addition, if you want to combine the torque detector with the requirements of each hand tool, to design and manufacture different torque detection hand tools, you must spend more design and manufacturing costs, and it is not applicable to all hand tools.
