How to use the torque wrench of Marshine The classification of the torque wrench and the torque presets

October 19, 2018

As we all know, the torque wrench is a special tool for tightly controlling the tightening torque of bolts and nuts, which consists of a controller and a tightening shaft. Dongri torque wrench is a type of torque wrench manufactured by Marshine. It is widely used in today's machinery manufacturing field. Torque wrench is an indispensable tool in measuring screw torque, breaking twisting force and fastening screws. . The following Steve lee will introduce the use of Dongri torque Wrenches, classification of torque wrenches, and torque presets.

East day torque wrench method of use


1. In the use of the torque wrench of Dongri, firstly, according to the requirements of measuring the workpiece, select the mid-range torque torque wrench, the measured torque value can not be less than 20 percent of the torque range in use, too large range Should not be used for the reinforcement of small torque parts, small-scale torque devices can not be over-range;

2. When using the Dongri torque wrench, first connect the wrench to the auxiliary parts (such as the sleeve, all kinds of mouthpieces) to ensure that the connection is no problem. Before strengthening the torsion force, set the required reinforcement value, and lock the locking device, adjust the direction change button to the direction of force, and then use it to operate 5-6 times in rapid succession, so that the internal components of the wrench The special lubricant can be fully lubricated, enabling the Dongri torque wrench to be more precise and durable.

3, when measuring, hand to grasp the effective range of the handle, along the direction perpendicular to the direction of the East Japan torque wrench shell, slowly increase the force until you hear the torque torque wrench issued a "tower" sound, at this time East Japan torque The wrench has reached the preset torque value. After the workpiece has been energized, the force should be released in time to avoid damaging other components. In the process of applying force, according to the national standard instrument operation specification, the verticality deviation should not exceed 10 degrees. The vertical deviation should not exceed 3 degrees in the horizontal direction. The operator should ensure that the range of up, down, left and right exertion does not exceed 15 degrees during use;

4. In order to prevent the measurement result from being affected by horizontal and vertical deviations, during the measurement, a vertical downward stable force value should be applied on the forcing grip end, and then manually add the point force so that the use value is more Accurate.

5, Marshine torque wrench readings: If it is with a table torque instrument, directly read the data indicated by the pointer for the measurement data value; if the sleeve plus sub-scale indicator, you should read the scale on the main scale, In addition, the sum of the scale values on the sub-scale or differential barrel is the measured data value.

6,  Marshine torque wrench is a measurement tool, should be gently, can not replace the hammer hit, when not in use, please note that the torque is set to the minimum, stored in a dry place. Torque wrenches have a wide range of applications. When tightening torque, it is relatively simple. You only need to set the required torque value to operate.


Classification of torque wrench


Torque instruments are divided into three categories according to the display mode and working principle of torque instruments.

1, torque table

According to the reactive force of the force, the torque is applied to the force point externally to drive the lever mechanism which has applied a certain load inside the instrument, and the mechanical gear is driven to make the pointer on the dial rotate regularly under the action of the externally applied force. Displays the existing torque value.

2, torque batch (also known as torque screwdriver)

According to the characteristics of the force, a negatively applied force is used. When the externally applied torsion reaches a preset value and is equal to the internal set value, the internal skip mechanism is actuated and a click sound can be heard. Indicates that the preset value has been reached.

3, torque wrench (also known as torque wrench)

The principle is similar to that of torque. The lever principle is used together with the skip mechanism. When the externally applied torque is greater than the internally set force value, the internal skip mechanism acts and releases the force, indicating that the preset force value has been reached and can be heard at the same time. To the sound produced by skipping.


Torque wrench torque presets


1. When presetting the torque value, pull down the locking ring on the handle of the board and turn the handle at the same time to adjust the main scale line and differential scale line data of the scale to the required torque value. After adjustment, loosen the lock ring and the handle locks automatically.

2. Install the corresponding size sleeve on the side of the board and cover the fasteners, then slowly apply force on the handle. When applying external force, it must be in the direction of the indicated arrow. When tightened until a signal "click" is heard (the preset torque value has been reached), stop the boost.

3, when the large-size torque board is used, the long-length sleeve can be added to facilitate the operation.

4. If it is not used for a long time, adjust the ruler marking line to the minimum torque data point.

The use of torque wrenches, the classification of torque wrenches, and torque presets are introduced here. Torque wrenches are bolts, screws, nuts, and other threaded retaining bolts or nuts. Firmware's hand tools. With the advantages of high precision, low failure rate, long life, programmable, torque control and angle control, and various torque options, it has been welcomed by many users.
