扭力扳手使用方法：
Usage of torque wrench:
1、選用合適量程的扭力扳手。力扳手的使用中，要根據(jù)測(cè)量工件的要求，選取適中量程扭力扳手，所測(cè)扭力值不可小于扭力器在使用中量程的百分之二十，太大的量程不宜用于小扭力部品的加固，小量程的扭力器更不可以超量程使用。
1. Select the appropriate range of torque wrench. In the use of the torque wrench, first of all, according to the requirements of the measuring workpiece, select a torque wrench with moderate range. The measured torque value shall not be less than 20% of the range of the torque device in use. Too large range shall not be used for the reinforcement of small torque parts, and the small range torque device shall not be used beyond the range.
2、根據(jù)工件所需扭矩值要求，確定預(yù)設(shè)扭矩值。預(yù)設(shè)扭矩值時(shí)，將扳手手柄上的鎖定環(huán)下拉，同時(shí)轉(zhuǎn)動(dòng)手柄，調(diào)節(jié)標(biāo)尺主刻度線和微分刻度線數(shù)值所需扭矩值。調(diào)節(jié)好后，松開鎖定環(huán)，手柄自動(dòng)鎖定。
2. Determine the preset torque value according to the required torque value of the workpiece. When preset the torque value, pull down the locking ring on the wrench handle, turn the handle at the same time, and adjust the main scale line and differential scale line of the scale to the required torque value. After adjustment, release the locking ring and the handle will lock automatically.
3、確認(rèn)扭力扳手與固定件連接可靠并已鎖定、用扭力扳手時(shí)，先將扳手方榫連接好輔助配件(如套筒，各類批嘴)，確保連接已經(jīng)沒問題。在加固扭力之前，設(shè)定好需要加固的力值，并鎖好緊鎖裝置，調(diào)整好方向轉(zhuǎn)換鈕到加力的方向，然后在使用時(shí)先快速連續(xù)操作5-6次，使扳手內(nèi)部組件上特殊潤(rùn)滑劑能充分潤(rùn)滑，使扭力扳手更精確，持久使用。
3. Confirm that the connection between the torque wrench and the fixed parts is reliable and locked. When using the torque wrench, first connect the square tenon of the wrench to the auxiliary accessories (such as socket and various nozzles) to ensure that the connection is no problem. Before strengthening the torque, set the force value to be strengthened, lock the locking device, adjust the direction change button to the direction of the force application, and then operate the torque wrench for 5-6 times in a quick and continuous manner, so that the special lubricant on the internal components of the wrench can be fully lubricated, making the torque wrench more accurate and durable.
