Usage of fixed torque electric wrench:

電動(dòng)扳手是定扭矩的，因此在擰緊扳手時(shí)必須注意扳手的使用范圍，以防止螺栓被檸斷。

Electric wrenches are fixed torque, so when tightening the wrench, it is necessary to pay attention to the range of use of the wrench to prevent the bolt from being broken.

定扭矩電動(dòng)扳手一般裝配一個(gè)螺紋件，沖擊時(shí)間為2到3秒，通常不應(yīng)超過5秒。

A fixed torque electric wrench is usually equipped with a threaded component, and the impact time is 2 to 3 seconds, usually not exceeding 5 seconds.

定扭矩電動(dòng)扳手的電壓過高過低均不宜使用。 空轉(zhuǎn)時(shí)，如果有任何異常現(xiàn)象，例如火花，噪音等，必須在故障排除后使用。 變換轉(zhuǎn)向時(shí)先用電源開關(guān)切斷電源，然后扳動(dòng)正反轉(zhuǎn)開關(guān)以保護(hù)正反轉(zhuǎn)開關(guān)。

Fixed torque electric wrenches should not be used if their voltage is too high or too low. When idling, if there are any abnormal phenomena, such as sparks, noise, etc., it must be used after troubleshooting. When changing direction, first cut off the power supply with the power switch, and then pull the forward and reverse switches to protect the forward and reverse switches.

定扭矩電動(dòng)扳手的特點(diǎn)：操作方便，省時(shí)省力，扭矩可調(diào)。

The characteristics of a fixed torque electric wrench: easy to operate, time-saving and labor-saving, and adjustable torque.

A.在使用定扭矩電動(dòng)扳手時(shí)，要根據(jù)被測(cè)工件的要求選擇一個(gè)適中量程的扭矩扳手。 測(cè)得的扭矩值不應(yīng)小于使用中量程的20％。 太大的量程不適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。

A. When using a fixed torque electric wrench, the first step is to select a torque wrench with a moderate range according to the requirements of the tested workpiece. The measured torque value should not be less than 20% of the mid range used. Too large a range is not suitable for reinforcing small torque components, and small range torque devices cannot be used beyond the range.

B.使用定扭矩電動(dòng)扳手時(shí)，將扳手的方榫連接到輔助配件，確保連接沒有問題。 在加固扭力之前設(shè)置需要加固的力值，鎖好緊鎖裝置，調(diào)整好方向轉(zhuǎn)換鈕到加力的方向，然后在使用過程中快速連續(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，從而使扭矩扳手更加精確和耐用。

B. When using a fixed torque electric wrench, first connect the square tenon of the wrench to the auxiliary accessory to ensure that there are no problems with the connection. Before tightening the torque, set the force value that needs to be tightened, lock the locking device, adjust the direction switch button to the direction of the applied force, and then quickly and continuously operate it 5-6 times during use to ensure that the special lubricant on the internal components of the wrench can be fully lubricated, making the torque wrench more precise and durable.

C.測(cè)量時(shí)，手應(yīng)握住手柄的有效范圍，并沿垂直于扭矩扳手殼體方向緩慢施加力，直到定扭矩電動(dòng)扳手發(fā)出“塔”聲，此時(shí)扭矩扳手已達(dá)到 預(yù)置扭力值。 工件已加力完畢，應(yīng)及時(shí)解除作用力，以免損壞其他零件。 在施加力的過程中，按照標(biāo)準(zhǔn)的儀器操作規(guī)范，垂直度的偏差不應(yīng)超過10度。 在水平方向上的上下偏差不應(yīng)超過3度，并且操作人員應(yīng)確保在使用過程中上下左右施力范圍不超過15度。

C. When measuring, the hand should hold the effective range of the handle and slowly apply force in the direction perpendicular to the torque wrench housing until the fixed torque electric wrench emits a "tower" sound, at which point the torque wrench has reached the preset torque value. The workpiece has been applied with force, and the force should be released in a timely manner to avoid damaging other parts. During the process of applying force, the deviation from perpendicularity should not exceed 10 degrees according to the national standard instrument operation specifications. The deviation in the horizontal direction should not exceed 3 degrees, and the operator should ensure that the range of force application from top to bottom, left to right, does not exceed 15 degrees during use.

D.為了防止測(cè)量結(jié)果受到水平和垂直方向上的偏差的影響，在測(cè)量過程中，應(yīng)在加力把持端上施加一個(gè)垂直向下的穩(wěn)定力值，然后手動(dòng)施加力，以便結(jié)果更精確。

D. In order to prevent the measurement results from being affected by deviations in the horizontal and vertical directions, a vertically downward stable force value should be applied to the force application control end during the measurement process, and then the force should be manually applied to make the results more accurate.
