定扭矩電動(dòng)扳手也稱為力矩扳手,是一種電動(dòng)扳手,它的主要特點(diǎn)是可以設(shè)置扭矩,并且可以調(diào)節(jié)扭矩,主要用于鋼結(jié)構(gòu)安裝行業(yè),專門從事鋼結(jié)構(gòu)高強(qiáng)度螺栓的安裝。 高強(qiáng)度螺栓是用來(lái)連接鋼結(jié)構(gòu)接點(diǎn)的,通常以螺栓群的形式出現(xiàn)。
Constant torque electric wrench, also known as torque wrench, is a kind of electric wrench. Its main feature is that it can set the torque and adjust the torque. It is mainly used in steel structure installation industry, specializing in the installation of high-strength bolts in steel structure. High strength bolts are used to connect steel structure joints, usually in the form of bolt group.
定扭矩電動(dòng)扳手使用方法:
Usage of constant 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。
The electric wrench has a constant torque, so the use range of the wrench must be paid attention to when tightening 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(guò)5秒。
The constant torque electric wrench is generally equipped with a threaded part, and the impact time is 2 to 3 seconds, usually not more than 5 seconds.
定扭矩電動(dòng)扳手的電壓過(guò)高過(guò)低均不宜使用。 空轉(zhuǎn)時(shí),如果有任何異?,F(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)。
The constant torque electric wrench should not be used when the voltage is too high or too low. During idling, if there is any abnormal phenomenon, such as spark, noise, etc., it must be used after troubleshooting. When changing the direction, first use the power switch to cut off the power supply, and then pull the forward and reverse switch to protect the forward and reverse switch.
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)。
Features of constant torque electric wrench: easy to operate, time-saving and labor-saving, torque adjustable.
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 the constant torque electric wrench, we should first select a moderate range of torque wrench according to the requirements of the measured workpiece. The measured torque value should not be less than 20% of the range in use. Too large measuring range is not suitable for the reinforcement of small torque parts, and small measuring range can not exceed the measuring 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(méi)有問(wèn)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(guò)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 the constant torque electric wrench, first connect the square tenon of the wrench to the auxiliary accessories to ensure that there is no problem in the connection. Before reinforcing the torque, set the force value to be reinforced, lock the locking device, adjust the direction change button to the direction of force application, and then operate 5-6 times continuously in the process of use, so that the special lubricant on the internal components of the wrench can be fully lubricated, so as to make the torque wrench more accurate 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(guò)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(guò)10度。在水平方向上的上下偏差不應(yīng)超過(guò)3度,并且操作人員應(yīng)確保在使用過(guò)程中上下左右施力范圍不超過(guò)15度。
C. When measuring, the hand should hold the effective range of the handle, and slowly apply the force along the direction perpendicular to the shell of the torque wrench until the constant torque electric wrench makes a "tower" sound, and the torque wrench has reached the preset torque value. After the workpiece has been loaded, the force should be released in time to avoid damaging other parts. In the process of applying force, the deviation of perpendicularity should not exceed 10 degrees according to the national standard instrument operation specification. The up and down deviation in the horizontal direction should not exceed 3 degrees, and the operator should ensure that the range of up, down, left and right force application does not exceed 15 degrees.
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(guò)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 the deviation in the horizontal and vertical directions, in the measurement process, a vertical downward stable force value should be applied on the force control end, and then the force should be applied manually to make the results more accurate.
