In this section, the video introduces measuring tools used in automotive workshops and discusses the different types of measuring instruments.
Types of Measuring Instruments
- Mechanical measuring instruments are used to measure length, width, depth, outer diameter, or inner diameter of an object. Some examples include:
- Steel ruler: Used to measure various dimensions of an object.
- Feeler gauge: Used to measure small distances or gaps between two surfaces.
- Vernier caliper: Used to measure outer diameter, inner diameter, thickness, and depth of an object.
- Electrical measuring instruments are also used in the automotive field but are not discussed in this video.
- Pneumatic measuring instruments are another type of measuring instrument used in the automotive sector but are not covered in this video.
Measuring Tools for Automotive Repair Shops
This section focuses on specific mechanical measuring tools commonly used in automotive repair shops.
Mechanical Measuring Tools
- Steel ruler: Used to measure length, width, height, and depth of an object. It has a level of accuracy ranging from 0.5 mm to 1 mm.
- Feeler gauge: A thin slab with different thicknesses ranging from 0.01 mm to 1 mm. It is used to measure small distances or gaps between two surfaces.
- Vernier caliper (caliper): A mechanical measuring tool with several parts including lower jaw, upper jaw, main scale, locking screw, and vernier scale. It is used to measure outer diameter, inner diameter, thickness, and depth of an object. It has different levels of accuracy ranging from 0.01 mm to 1/1000 inch.
- Micrometer (screw micrometer): A type of mechanical measuring instrument used to measure length, thickness, and outer diameter of an object with a high level of accuracy (0.01 mm).
- Inside micrometer: Used to measure the inside diameter of an object with a higher level of accuracy compared to a caliper. It is available in different sizes and does not have a framework like a regular micrometer.
- Dial indicator (dayclick): A mechanical measuring tool used to check for deviations from flatness on round or curved surfaces.
Conclusion
This video provides an overview of various mechanical measuring tools used in automotive repair shops. The discussed tools include steel ruler, feeler gauge, vernier caliper, micrometer, inside micrometer, and dial indicator. Each tool serves specific purposes in measuring dimensions and checking for deviations in automotive parts.
New Section
This section provides an introduction to the dial indicator and its usage in measuring cylinder bores.
How to Use the Dial Indicator
- First, install the dial gauge on the support rod.
- Next, calibrate the dial gauge.
- Take measurements using the dial indicator.
- Read the measurement results of the dial indicator.
New Section
This section explains the components of a bore gauge cylinder and how to measure cylinder diameter using it.
Components of Bore Gauge Cylinder
- The bore gauge cylinder consists of a dial gauge for measurement readings.
- It also includes a part for holding or tying the dial.
- There is a replacement road to increase the touch area on the cylinder being measured.
- A replacement washer is used to increase length.
- The manshurin point is a measurement point.
Measuring Cylinder Diameter with Bore Gauge Cylinder
- Start by using a caliper to measure cylinder diameter.
- Select appropriate replacement rods and washers.
- Calibrate the bore gauge cylinder.
- Insert the cylinder bore gauge into the cylinder.
- Read and record any deviations indicated by the dial gauge.
New Section
This section discusses analyzing measurement results obtained from using a bore gauge cylinder.
