Scale torque tightening wrench - tightening bolt torque wrench

SGTG modeltorque wrenchAdjustable torque, when the torque reaches the preset amount, it automatically falls off and sends a signal to ensure that all fastening nuts of the anchor rod are under the same force. It is used in conjunction with a socket wrench socket to tighten hexagonal bolts and nuts. High precision and good stability, especially suitable for torque measurement of fasteners with high requirements. It can be rotated left and right, with a torque accuracy of ± 3%.Scale type torque tightening wrenchIt is a mechanical torque wrench,Dual scale display,Equipped with two main and auxiliary scales, the torque value can be adjusted freely within the specified torque range, making the operation simple and convenient.atWhen tightened, it can indicate the torque value.It can reduce the operator's effort and easily disassemble threaded fasteners. When the tightening torque of the fastener reaches the preset value, it can automatically emit a 'click' signal accompanied by obvious tactile vibration,No need to read them one by one,

The usage method of the scale torque tightening wrench

1. Choose a torque wrench with appropriate range

In the use of preset torque wrenches, the first step is to select a torque wrench with a moderate range according to the requirements of the measured workpiece. The measured torque value should not be less than 20% of the range of the torque tester in use. A too large range should not be used for reinforcing small torque components, and a small range torque tester should not be used beyond the range;

2. Determine the preset torque value based on the required torque value of the workpiece.

When setting the torque value, pull down the locking ring on the wrench handle and rotate the handle to adjust the values of the main and differential scale lines of the ruler to the desired torque value. After adjustment, release the locking ring and the handle will automatically lock.

3. Confirm that the torque wrench is securely connected to the fixing component and has been locked

When using a torque wrench, first connect the square tenon of the wrench to the auxiliary accessories (such as sockets, various types of nozzles) to ensure that the connection is correct. Before reinforcing the torque, set the force value that needs to be reinforced, lock the sub locking device, and adjust the direction switch knob to the direction of the applied force Then, when using, quickly and continuously operate 5-6 times to ensure that the special lubricant on the internal components of the wrench can be fully lubricated, making the torque wrench more durable and long-lasting.

4. Method of applying force with torque wrench

Install the corresponding socket on the square tenon of the wrench and secure it with the fastener, then slowly apply force on the handle. When applying external force, it must be in the direction indicated by the arrow.

Grasp the effective range of the handle with your hand, slowly apply force in a direction perpendicular to the torque wrench housing, until you hear the torque wrench make a 'tower' sound. When tightened to a signal of 'click' (reaching the preset torque value), stop applying force. Completed one assignment.

At this point, the torque wrench has reached the preset torque value, and the workpiece has completed the force application. Then, the force should be released in a timely manner to avoid damaging other components.

During the force application process, according to the national standard instrument operation specifications, the vertical deviation should not exceed 10 degrees on both sides. The horizontal deviation should not exceed 3 degrees, and the operator should ensure that the range of force applied in all directions does not exceed 15 degrees during use.

5. When using a large-sized torque wrench, an additional extension rod can be added for easy operation.

6. The measurement results may be affected by deviations in the horizontal and vertical directions. When measuring, a stable vertical downward force should be applied to the gripping end, and then additional force should be added to achieve more accurate results.

7. A wrench is a measuring tool and should be handled with care. It cannot replace a hammer for striking. When not in use, please set the torque to the minimum value and store it in a dry place. The range of torque is relatively wide, and when reinforcing torque, it is relatively simple. Only the required torque value needs to be set for operation.

8. If not in use for a long time, adjust the scale markings to the minimum torque value. Beneficial for ensuring the accuracy of torque.

TipsAdd a sleeve at the end to extend the force arm to prevent damage to the torque wrench.

（1）Adjust the required torque as needed and confirm that the adjustment mechanism is in a locked state before use.

（2）When using a torque wrench, the load should be balanced and slowly applied. Do not pull or press forcefully to avoid overloading and inaccurate output torque. After reaching the preset torque, the loading should be stopped.

（3）Sliding torque installation wrench After use, it should be adjusted to torque to fully relax the force measuring spring and extend its lifespan.

（4）Water should be avoided from entering the sliding torque installation wrench To prevent parts from rusting.

（5）The opening size of the selected torque wrench must match the size of the bolt or nut. If the opening of the wrench is too large, it is easy to slip and damage the hexagon of the screw. In car maintenance, attention should be paid to the selection of wrench metric and imperial systems;The selection principles for various types of wrenches generally prioritize socket wrenches, followed by ring wrenches, open-end wrenches, and then adjustable wrenches.

（6）To prevent damage and slippage of the wrench, the tension should be applied to the thicker side of the opening. This is especially important for adjustable wrenches that are subjected to high stress to prevent the opening from appearing'eighty percent'Character shape, damaged nut and wrench.

（7）A torque wrench is designed based on the strength of human hands. When encountering tight threaded parts, the wrench cannot be hit with a hammer;Except for socket wrenches, other wrenches cannot be equipped with a force rod to prevent damage to the wrench or threaded connection

（8）When using a torque wrench, when hearing'snap'At this moment, it is appropriate to make a sound.

Verification certificate for preset torque wrench

presetA torque wrench is a specialized tool for precisely controlling the locking torque of bolts and nuts. It should be used correctly according to the following requirements. The following is an introduction to torque adjustment and torque wrench readings

1、 Torque regulation

1.Double sided scale: The front scale isN- mCow rice, with a reverse scale ofFt-L bFoot pound.

2.When setting the torque value, push down the knob at the end of the handle to unlock it, and then rotate the handle to adjust the ruler to the desired value. After setting the torque, push it up to lock the torque value and start the operation.

3.Torque adjustment: such as setting the torque value to192N. MRotate the dial of the secondary scale until the main scale points190Flat position. The main scale is190Afterwards, align the secondary scale2Adjust to192N. MThe value of the main scale will be linked to the secondary scale like the short and long hands of a clock

2、 Reading of wrench

If it is a torque instrument with a meter, directly reading the data indicated by the pointer is the measured data value; If it is a sleeve with a secondary scale indicator, the scale value on the main scale should be read first, and then the sum of the scale values on the secondary scale or differential cylinder should be added to obtain the measurement data value.

Torque magnitude=The reading size of the torque main scale indicator line+Secondary scale (differential scale) reading size
