What is the method of detecting mechanical parts processing?

During the processing of mechanical parts , it is normal to have fault problems, but they must be solved in time. However, sometimes some faults cannot be discovered, so they are discovered later in use, so many users must learn how to make a choice when making a choice. It is very important to inspect the product. If you find a problem after buying it and some merchants are not responsible, then let’s learn about what inspection methods are used for mechanical parts processing?

1. Outer diameter measurement method

When measuring the outer diameter, two parts need to be measured every week and recorded. When the workpiece is of the same diameter as the diameter is greater than 50 mm, straightness check should be performed, the blade ruler and the outer diameter busbar should be contacted by the blade ruler, the width of the floor is observed, and then the standard light gap should be judged;

2. Inner diameter measurement method

When measuring the inner diameter of the part, only three times a week are required and keep records. For lengths of the same diameter greater than 40 mm, cylindricality checks should be performed, and two larger positional spacings should be obtained within the direction range of the same diameter length. Calculation of cylindrical error;

3. External thread measurement method

The outer diameter is measured by a spiral rangefinder or a three-pin rangefinder, and the small diameter is detected by a spiral rangefinder (general gauge);

4. Method for measuring internal threads

Inner diameter and outer diameter thread plug gauge (general gauge) inspection, inner diameter and outer diameter and inner diameter inspection;

5. Surface roughness inspection

Comparison and judgment are made through sample block comparison method;

6. Flatness test

The present invention provides an adjustable bearing on a flat plate, the part measuring surface facing up, and the support point is adjusted so that the heights of the three points are equal, and the measured peak and valley value is the plane plane error.

The above points are our inspection methods for mechanical parts processing . Today we will explain it here. If you want to know more information, please follow the Dongguan Ruibang Technology website to view detailed information.
