TORQUE WRENCH
Q1:Definition and Overview
A torque wrench is a handheld tool used to apply a specific amount of rotational force, or
torque, to an object, such as a bolt or nut. It is designed to ensure that the correct
amount of torque is applied to avoid over-tightening or under-tightening, which can
damage the object or surrounding material.
Q2: What is its primary purpose or function?
The primary purpose or function of a torque wrench is to:
Apply a precise amount of rotational force (torque) to:
1. Tighten or loosen bolts and nuts
2. Ensure proper tightening or loosening of fasteners
3. Prevent over-tightening or under-tightening
4. Maintain accuracy and consistency in torque application
By providing a precise and controlled amount of torque, a torque wrench helps to:
- Prevent damage to fasteners, surrounding material, or equipment
- Ensure safety and reliability in various industries, such as automotive, aerospace, and
construction.
Q3: Types or Models
Here are some common types or models of torque wrenches:
1. Click-Type Torque Wrench
- Provides a audible click when set torque is reached
- Commonly used in automotive and industrial applications
2. Slip-Type Torque Wrench
- Slips or releases when set torque is reached
- Often used in applications where over-tightening is a concern
3. Digital Torque Wrench
- Displays torque value on an LCD screen
- Often features memory storage, units conversion, and accuracy calibration
4. Hydraulic Torque Wrench
- Uses hydraulic pressure to generate torque
- Commonly used in heavy industry, such as construction and oil & gas
5. Pneumatic Torque Wrench
- Uses compressed air to generate torque
- Often used in applications where high torque output is required
6. Electric Torque Wrench
- Uses an electric motor to generate torque
- Commonly used in applications where high torque output and precision are required
7. Manual Torque Wrench
- Requires manual effort to generate torque
- Often used in applications where low to moderate torque output is required
8. Torque Multiplier
- A device that amplifies the torque output of a torque wrench
- Often used in applications where extremely high torque output is required
Q4: Assembly of Parts
Here’s a breakdown of the assembly of parts for a typical torque wrench:
1. Handle
- Material: Metal, plastic, or composite
- Function: Provides grip and control for the user
2. Shaft
- Material: Metal (e.g., steel or aluminum)
- Function: Connects the handle to the gear box
2
3. Gear Box
- Material: Metal (e.g., steel or aluminum)
- Function: Houses the gear mechanism that multiplies the torque
4. Gear Mechanism
- Material: Metal (e.g., steel or brass)
- Function: Multiplies the torque applied by the user
5. Torque Sensor
- Material: Electronic components (e.g., strain gauges or piezoelectric sensors)
- Function: Measures the torque applied to the wrench
6. Display Unit (optional)
- Material: Electronic components (e.g., LCD screen or LED display)
- Function: Displays the torque value, units, and other relevant information
7. Ratchet Mechanism (optional)
- Material: Metal (e.g., steel or aluminum)
- Function: Allows for easy tightening or loosening of fasteners
8. Socket or Drive
- Material: Metal (e.g., steel or aluminum)
- Function: Attaches to the wrench and engages with the fastener
9. Calibration Mechanism (optional)
- Material: Electronic components (e.g., potentiometers or calibration switches)
- Function: Allows for calibration of the torque wrench to ensure accuracy
Q5: Complete Working Process
Here’s a step-by-step explanation of the complete working process of a torque wrench:
Preparation
1. *Selecting the correct torque wrench*: Choose a torque wrench that matches the
required torque specification and drive size.
2. *Calibrating the torque wrench (if necessary)*: Ensure the torque wrench is calibrated
to the correct torque value.
3
3. *Attaching the socket or drive*: Attach the correct socket or drive to the torque
wrench.
Setting the Torque Value
1. *Determine the required torque value*: Check the manufacturer’s specifications or
consult with a supervisor to determine the required torque value.
2. *Set the torque value on the wrench*: Use the torque wrench’s adjustment mechanism
to set the desired torque value.
Applying Torque
1. *Place the socket or drive on the fastener*: Position the socket or drive on the fastener,
ensuring proper engagement.
2. *Apply force to the handle*: Hold the torque wrench firmly and apply force to the
handle in a smooth, consistent motion.
3. *Reach the set torque value*: Continue applying force until the torque wrench reaches
the set torque value, indicated by a click, beep, or other signal.
Verifying Torque
1. *Check the torque value*: Verify that the torque wrench has reached the set torque
value.
2. *Confirm the fastener is secure*: Ensure the fastener is properly secured and not loose.
Safety Precautions
1. *Use proper technique*: Avoid using excessive force or jerky motions, which can
damage the torque wrench or surrounding components.
2. *Wear protective gear*: Wear safety glasses, gloves, and other protective gear as
necessary.
3. *Regularly inspect and maintain the torque wrench*: Ensure the torque wrench is
properly calibrated, stored, and maintained to prevent damage or inaccurate readings.
