Cad drawing of threaded hole

The Cad drawings of threaded holes are as follows:

Material preparation: computer, running system Windows7 and above, software CAD.

Operating steps:

1. First, open a part of the drawing with CAD software on the computer, and you can see that the drawing in the drawing lacks threads.

2. Then draw a diagonal of 45 and a diagonal of 120 respectively, as shown in the figure.

3. Draw a line segment with a length of 26.944 upward from the center line. Here is the American 12# thread, and 26.944 is the major diameter of the thread, which can be drawn according to the actual thread size source.

4. Then draw a straight line to the right from the midpoint of the 26.944 line segment.

5. Then trim and delete the redundant line segments according to the shape shown below.

6. Then draw a diagonal line with an angle of 60, as shown in the figure.

7. Then extend the short line on the right to make it oblique to 60.

8. Then prune in CAD to achieve the effect in the last hundred pictures.

9. Then mirror the short line to form a V-shape.

10. Continue to mirror the V line segment composed of two short lines to the right until it is the same as the figure.

1 1, execute the trim command again to delete unnecessary lines, and the thread will be half finished.

12, and then mirror the image with the center line as the axis, as shown in the figure.

13. Finally, stagger the V-shape with straight lines. After completing the above settings, you can draw screws and threads in cad software.

Other functions of learning CAD well:

1, improve work efficiency

Learning and mastering CAD software can significantly improve work efficiency. Compared with traditional manual drawing, CAD software can complete drawing quickly and accurately, and it is convenient to modify and correct. At the same time, CAD has rich graphic libraries and functional modules, which can simplify complex design steps, save a lot of time and improve work efficiency.

2. Improve professional ability

Learning CAD well plays an important role in improving personal professional ability in the fields of architecture, engineering and design. After mastering CAD skills, you can better carry out graphic design, elevation design and structural design, and deepen your understanding and application of professional knowledge. CAD skill is also a necessary condition for many enterprises to recruit, and mastering it is conducive to improving competitiveness.

3. Broaden the career development path

Mastering CAD skills can broaden personal career development. CAD is widely used in architecture, engineering, manufacturing, interior design and other fields, and has become one of the indispensable skills in these industries. People with CAD skills have more advantages in job hunting and career promotion, and can play a role in a wider range of industries and fields.
