电动扭剪扳手的维护管理和正确使用方法

由于电动扭剪扳手是高频应用工具,为了提高测量精度,有必要定期校准和检查工具,并配置满足使用要求的电动扭剪扳手设备。目前,电动扭剪扳手主要由检定仪对电动扭剪扳手进行校准,检定仪需要定期检查。由于校准环境是试验室环境,因此与现场操作环境有很大的不同。为了确保校准管理的有效性,有必要参考实际使用现场进行管理,并且要求误差不受使用场合的影响。使用前要注意检查电动扭剪扳手的准确性,并根据使用频率调整校准和维护的频率。通常每年不少于一次,利用维护管理手段保证电动扭剪扳手的准确性。

As the electric wrench is a high-frequency application tool, in order to improve the measurement accuracy, it is necessary to calibrate and inspect the tool regularly, and configure the electric wrench equipment to meet the use requirements. At present, the electric torque wrench is mainly calibrated by the calibrator, which needs to be checked regularly. Because the calibration environment is a laboratory environment, it is very different from the field operation environment. In order to ensure the effectiveness of calibration management, it is necessary to refer to the actual use site for management, and the error is not affected by the use of occasions. Before use, pay attention to check the accuracy of the electric wrench, and adjust the frequency of calibration and maintenance according to the frequency of use. Usually not less than once a year, the use of maintenance management means to ensure the accuracy of electric torque wrench.
电动扭剪扳手的正确使用方法:
The correct use of the electric wrench is as follows:
电动扭剪扳手
电动扭剪扳手主要用于安装紧固件,例如螺栓,螺钉和螺母。通过扭矩控制,确保了螺纹的拧紧,并且不会因扭矩过大而损坏螺纹。因此,有必要使用电动扭剪扳手进行扭矩值固定操作。
Electric wrench is mainly used to install fasteners, such as bolts, screws and nuts. Through torque control, the tightening of thread is ensured, and the thread will not be damaged due to excessive torque. Therefore, it is necessary to use the electric wrench to fix the torque value.
在施加过程中需要预先设置固定扭矩值。当达到设定值时,电动扭剪扳手将发出提醒信息,可以感觉到手部振动或听到“喀哒”声,即扭矩已完成。当扭矩值达到固定位置时,无需继续施加力。请勿使用冲击力,停止施加力后,各个零件复位。施加扭矩时,将手握在电动扭剪扳手手柄的中间刻度线上,并仅在电动扭剪扳手指示的方向上施加力,同时施力方向应在±15°以内(垂直方向和水平方向)。
In the process of application, the fixed torque value needs to be set in advance. When the set value is reached, the electric wrench will send out a reminder message, and you can feel the hand vibration or hear the "click" sound, that is, the torque has been completed. When the torque value reaches a fixed position, there is no need to continue to apply force. Do not use impact force. After the force is stopped, all parts will be reset. When applying torque, hold your hand on the middle scale line of the handle of the electric torsional shear wrench, and apply force only in the direction indicated by the electric torsional shear wrench. At the same time, the force application direction should be within ± 15 degrees (vertical direction and horizontal direction).
根据紧固件的强度和扭矩用以使用合适量程的扳手,并且不允许超过扳手的适用范围。扳手在使用前需要调零,无荷载时注意对扭矩扳手指针的检查,看指针是否在零标度值上,如果不是则需要对其进行调整。
According to the strength and torque of the fastener, the wrench with appropriate range shall be used, and the application scope of the wrench shall not be exceeded. The wrench needs to be adjusted to zero before use. When there is no load, pay attention to check the pointer of the torque wrench to see whether the pointer is on the zero scale value. If not, it needs to be adjusted.
为确保读数准确,在使用过程中需要用一只手握住扳手的手柄,使扭矩扳手和拉力保持直角,并稳定地施加力。当指针指向扭矩值时,禁止用力过大,否则会出现误差值。测量完成后,旋转旋钮将指针返回到零位,以便进行下一个应用。作为测量工具,必须注意保护电动扭剪扳手。禁止进行扔掷、震动以及敲击等。
In order to ensure accurate reading, it is necessary to hold the handle of the wrench with one hand in the process of use, so that the torque wrench and the tension are kept at right angles, and the force is applied stably. When the pointer points to the torque value, do not use too much force, otherwise the error value will appear. After the measurement, rotate the knob to return the pointer to the zero position for the next application. As a measuring tool, we must pay attention to protect the electric wrench. Throwing, shaking and knocking are prohibited.
