What is RenhotecIC dial gauge, and how to use it?

 

The dial indicator is a length measuring tool, and is widely used to measure the geometric shape error and position error of the workpiece. The dial indicator has an anti-shock mechanism, long service life and reliable accuracy. Dial gauge is a high-precision length measuring tool, which is widely used to measure the geometric shape error and mutual position error of the workpiece.

 

Depth dial indicator is used to measure the depth of the workpiece, steps and other dimensions. It has the characteristics of reliable measurement and high precision.

 

The dial indicator is a kind of comparative measuring tool with high precision. It can only measure the relative value, not the absolute value. It is mainly used to detect the shape and position error of the workpiece (such as roundness, flatness, verticality, runout, etc. ), and can also be used to align the installation of the workpiece on the machine tool.

 

The dial indicator is often installed on a commonly used ordinary meter stand or a magnetic meter stand. When measuring, it should be noted that the measuring rod of the dial indicator should be perpendicular to the surface to be measured. Application of measurement: a) It is to check the circular runout of the outer circle to the hole and the circular runout of the end to the hole. b) is to check the parallelism of the two planes of the workpiece. c) Align the outer circle when installing the workpiece on the four-jaw chuck on the internal grinding machine.

 

Structural principle of dial indicator:

 

When the measuring rod moves up or down by 1mm, the gear transmission system drives the large pointer to make one revolution, and at the same time the small pointer to make one division. The large pointer reads 0.01mm per revolution, and the small pointer reads 1mm per revolution. The scale range at the small pointer is the measuring range of the dial indicator. The sum of the measured size pointer readings is the variation of the measured size. The dial can be rotated for the big pointer to zero when measuring. . The measurement accuracy of the dial indicator is 0.01mm.

 

How to read the dial indicator:

 

The reading method of the dial indicator is: first read the scale line that the small pointer turns (that is, the millimeter integer), then read the scale line that the big pointer turns (that is, the decimal part), and multiply by 0.01, and then add the two together, that is Get the measured value.

 

The difference between the dial gauge and the dial gauge:

 

It can be distinguished from two aspects: 1. Look at the accuracy: the accuracy of the dial indicator is 0.01mm, and the accuracy of the dial indicator is 0.001mm. These two dials are marked with accuracy, the standard accuracy is: 0.01mm is a dial indicator, and the standard accuracy is 0.001mm is a dial indicator. 2. Look at the range: the larger range of the dial indicator is generally 5-15mm. The smaller range of the dial indicator is generally 1-3mm.
