Description
本發明係一種扭力扳手，詳而言之係一種電子式棘輪套筒扭力扳手，且該用以偵測扭力值變化之應變規係設置於套筒接頭，藉由應變規與套筒之間具有極近的偵測距離，得進行更精密、準確的扭力值測量。 The invention relates to a torque wrench, in particular to an electronic ratchet sleeve torque wrench, and the strain gauge for detecting the change of the torque value is arranged on the sleeve joint, and the strain gauge and the sleeve have Very close detection distance, more precise and accurate torque measurement.
按，扳手工具利用槓桿原理對螺固工件進行扳動，達到扭緊或旋鬆的效果，而得藉由螺固件裝配、組合各類產業的零組件，一般工業成品因結構差異而需要使用各式螺固件，施以強弱不同的扭力組裝固定，像是重工業如航空、造船與轎車，其零組件得施以相當強度的扭力組裝才能成就堅實結構，承受氣壓、動力的衝擊，而精密工業如電子機械，其零組件就不能以過大的扭力組裝，才能確保其能精確運作使用；但無論何種工業成品，在以螺因件組合時不足一分扭力或超過一分扭力，都極可能造成結構與螺固件失去效用或損壞，而扳手工具正是扮演控制扭力的關鍵。 Press, the wrench tool uses the principle of lever to pull the screw-solid workpiece to achieve the effect of tightening or loosening. It is necessary to assemble and combine the components of various industries by the screw firmware. The general industrial products need to use each due to structural differences. Screws are assembled and fixed with different torsion forces, such as heavy industry such as aviation, shipbuilding and cars. Their components can be assembled with considerable strength to achieve a solid structure, withstand the impact of air pressure and power, while precision industries such as Electronic machinery, its components can not be assembled with excessive torque to ensure its precise operation; but no matter what kind of industrial products, less than one point of torque or more than one point of torque when combined with screw components is likely to cause The structure and the screw are ineffective or damaged, and the wrench tool is the key to controlling the torque.
