扭力扳手的使用方法及注意事項(xiàng)
Usage and precautions of torque wrench
使用預(yù)設(shè)扭矩扳手的注意事項(xiàng):扭矩扳手是精確控制螺栓螺母鎖緊扭矩的專用工具，應(yīng)按照以下要求正確使用:
Precautions for using preset torque wrench: torque wrench is a special tool to accurately control the locking torque of bolts and nuts, which should be used correctly according to the following requirements:
(1)不要使用預(yù)設(shè)扭矩扳手拆卸螺栓或螺母。
(1) Do not use a preset torque wrench to remove bolts or nuts.
(2)嚴(yán)禁在扭矩扳手末端增加套筒延長臂，以防損壞扭矩扳手。
(2) It is strictly forbidden to add a socket extension arm at the end of the torque wrench to prevent damage to the torque wrench.
(3)根據(jù)需要調(diào)整所需扭矩，確認(rèn)調(diào)整機(jī)構(gòu)處于鎖定狀態(tài)后方可使用。
(3) Adjust the required torque as required, and confirm that the adjustment mechanism is in the locked state before use.
(4)使用扭矩扳手時(shí)，要平衡緩慢加載，切勿猛拉猛壓，以免造成過載和輸出扭矩不對中。達(dá)到預(yù)設(shè)扭矩后，應(yīng)停止加載力。
(4) When using the torque wrench, it is necessary to balance and load slowly, and do not pull and press violently, so as to avoid overload and misaligned output torque. When the preset torque is reached, the loading force shall be stopped.
(5)使用預(yù)設(shè)的扭矩扳手后，應(yīng)將其調(diào)整到更小扭矩，使施力彈簧充分放松，以延長其使用壽命。
(5) After using the preset torque wrench, it should be adjusted to the minimum torque to fully relax the force spring, so as to extend its service life.
(6)避免水侵入預(yù)設(shè)扭矩扳手，防止零件生銹。所選扭矩扳手的開口尺寸必須與螺栓或螺母的尺寸一致。如果扳手的開口太大，很容易滑落，損壞螺釘?shù)牧?。根?jù)各種扳手的選擇原則，一般套筒扳手，其次是環(huán)形扳手，再次是開口扳手，是活動扳手。為防止扳手損壞和滑脫，應(yīng)將拉力施加在開口較厚的一側(cè)，特別注意受力較大的活動扳手，防止開口呈“八”字形，損壞螺母和扳手。
(6) Avoid water intrusion into the preset torque wrench to prevent parts from rusting. The opening size of the selected torque wrench must be consistent with the size of the bolt or nut. If the opening of the wrench is too large, it is easy to slip and damage the hexagon of the screw. According to the selection principles of various wrenches, socket wrenches are generally preferred, followed by ring wrenches, open-end wrenches, and finally adjustable wrenches. In order to prevent the wrench from being damaged and slipping, the tension should be applied to the side with thick opening, and special attention should be paid to the spanner with large force to prevent the opening from being "eight" shaped and damaging the nut and wrench.
