The inner surface shape deviation of the spherical head has an important influence on the sealing, safety and service life of the boiler. Therefore, accurate inspection of the inner surface shape deviation of the spherical head is a key link to ensure the quality of the boiler.

[0003] After searching, the utility model with the patent announcement number CN216385444U discloses a container head shape deviation inspection device, which has a long main ruler. The main ruler is a horizontal scale ruler. A moving claw is sleeved on one end of the main ruler. The top edge of the moving claw is provided with a moving claw upper jackscrew.
