What is the function of Caliper?

What is the function of Caliper? and how to use caliper when you measuring any things.

 Caliper is an indirect measuring tool that is used to measure the length, width, thickness, and diameter of a job or job with the help of steel rule. The calipers are often made of high carbon steel or soft steel. The seers are hardened and pined. High carbon steel calipers and surface hardened calipers with soft steel are rigged!

 
Working Principle of Measuring Tool Caliper

• The size of the caliper is revealed by their rivet pin or the second distance of the tip measuring from the center of the rebate. The caliper is used to measure and move the Reiti Mural and Outer Scale of various different objects.

Caliper type

You can measure the caliper as much as you want by measuring the calipers in inches or mm from the marks above the rule.

Try square and ruler

1 external caliper: -

 The outer caliper is used to measure the outer diameter and length and width of a round object. It is available in sizes from 100 to 150, 200, and 300 mm. The caliper capacity is the maximum measurement that can be taken and the side caliper is of two types. Consists of a simple caliper spring caliper.

2 inner calipers: -

Calipers useful for surface measurements are called in-side calipers. And they are mainly used to set the inner wiring wires, to move them on the object, or to check with the standards. These calipers are also available in 75 100 150 200 and 300 mm sizes. These calipers are also of two types There are sternal inner calipers, inner springing calipers.

Parts of Vernier caliper

Understand the parts of the Vernier caliper. Some models also have a depth gauge. The main scale is fixed to the place while the Vernier scale is named for the sliding scale that opens and closes the jaw.

Read the scales on your Vernier caliper.

 It reads your caliper scale like a simple ruler. Typically, a caliper is mainly marked with inches or centimeters, and there are small partitions between them. The sliding (vernier) scale should have a label that tells you what it represents.

• If the sliding scale does not have a label, you can assume that the numbered divisions represent 1/10 of the smallest divisions on the main scale.

• The main scale is life-size while the sliding scale is extended for easy reading. This system allows the Vernier caliper to be measured more accurately than a ruler.

Check the scale of your smallest divisions Before making the measurement, count the number of rows between the two numbers on your Vernier scale.

• If we exemplify numbers on a Vernier scale represent 0.1 inches, and there are five redundant lines between them. 0.1 "(inch) = 5 = 0.02 inch. So each of the redundant lines represents 0.02" (inch).

• Clean the item you are measuring. No grease should be on it and there is nothing in this way that would interfere with the static measurement.

• Screw unlock: If our vernier caliper has a locking screw, loosen it before starting.

• Rotating something to the right (clockwise) while rotating it to the left (counter-clockwise) will loosen it.

•

Close the jaws. Before anything is measured, the jaw and face are closed and the readings are reduced to zero so that you can get a better measurement. If you don't do this then you won't start with your scales queued at zero (0) when taking your measurements and you have to correct for zero error.

For example, if on a scale fixed with 1 mm on zero (0) sliding scale lines, you have a positive zero error of +1 mm (milli). Reduce 1 mm (milli) from all measurements to get the correct result.

• If the zero (0) on the sliding scale is to the left of the main scale zero, you have a negative zero (0) error. To see the size of the error, slide it to the zero lines while looking at another sign.

3 Jenny Calipers: -

They are also called Vishmapada coddling or hermaphrodite calipers. This soft steel is made of mild steel and its pavement has a hardened surface to prevent wear.

 
Jenny odd leg and adj. jenny calipers

 

It's one leg is straight and pointed like a divider, but the point of the other leg is turned inward about 3 to 6 centimeters, both legs are widened and the point is thinner with each other. Rivet is tightened by washer and washer The rivet is such that both the legs can be adjusted by light pressure. According to the texture of the straight point, the Jaini calipers are as follows: -

1 solid tip Jaini caliper:     Its work is made from straight leg.

2 Adjustable nozzle jenny caliper: 

Their working point is adjustable. This adjustable tip moves the screw in the straight leg screw so that the nut can be tightened tightly in the required position along the leg. This is also called middle tip jenny caliper goes.
