扭矩电动扳手的使用有8个要点

There are 8 key points in the use of torque electric wrench
所有的固定力矩扳手都要按照说明书操作,要点如下:
All fixed torque wrenches shall be operated according to the instructions, and the key points are as follows:
1. 根据需要的转矩值,选择相应的已通过校准的转矩扳手,不允许使用未通过校准的转矩扳手;
1. Select the corresponding calibrated torque wrench according to the required torque value, and it is not allowed to use the torque wrench that fails to pass the calibration;
2. 扳手应该以平衡而缓慢的力量拧动,而不是急剧的拧动。用手握住固定力矩扳手手柄的中点,将手柄垂直于扳手线方向拉动,直至达到要求的力矩。
2. The wrench should be screwed with a balanced and slow force rather than a sharp one. Hold the midpoint of the handle of the fixed torque wrench by hand and pull the handle perpendicular to the wrench line until the required torque is reached.
3.不得施加大于固定扭矩扳手额定扭矩的扭矩。不要用固定扭矩扳手拆卸螺栓或螺母。
3. Do not apply a torque greater than the rated torque of the fixed torque wrench. Do not use a fixed torque wrench to remove bolts or nuts.

4、使用固定力矩扳手拧紧螺栓时,不应使用转接头,不得使用,必须符合下列要求:转接头有多种不同形状,可以合理选用;为减小拧紧力矩误差,适配器长度应小于固定力矩扳手长度;当连接适配器时,其线路应与扳手线在一条直线上。如果需要,可以使用带有偏移轴的适配器,但角度不应超过15°。
4. When using the fixed torque wrench to tighten the bolt, the adapter shall not be used and must meet the following requirements: the adapter has a variety of different shapes and can be reasonably selected; In order to reduce the error of tightening torque, the length of adapter shall be less than the length of fixed torque wrench; When connecting the adapter, its line should be in line with the wrench line. If necessary, an adapter with an offset shaft can be used, but the angle should not exceed 15 °.
5. 固定力矩扳手不得作为普通扳手使用,如用于松开螺母、螺栓等;
5. The fixed torque wrench shall not be used as an ordinary wrench, such as for loosening nuts and bolts;
6、右转力矩固定力矩扳手不能左转,而左转力矩固定力矩扳手不能右转;
6. Right turn torque fixed torque wrench cannot turn left, while left turn torque fixed torque wrench cannot turn right;
7. 不要使用镀铬固定力矩扳手和转移扳手来接触钛和合金螺栓或产品结构;
7. Do not use chrome plated fixed torque wrench and transfer wrench to contact titanium and alloy bolts or product structure;
8. 固定扭矩扳手施加的扭矩不得超过该固定扭矩扳手的额定扭矩值。
8. The torque applied by the fixed torque wrench shall not exceed the rated torque value of the fixed torque wrench.
