Description

Technical Field

[0001] The utility model relates to the technical field of tooling inspection, in particular to an inspection tooling for iron casting products. Background Art

[0002] Iron casting products are made by dewaxing casting process, and then mechanically processed to obtain the required shape and size. The size is generally inspected by tools or equipment, which requires the operation of equipment or tools. Multiple size inspections are time-consuming and cumbersome to operate. For nail gun castings, such as the shell of the nail gun, the shell has two parallel holes. It is necessary to check whether the spacing between the two holes and the spacing with the bottom of the casting are within the design range. At present, manual inspection is used, which is to first check the spacing between the two holes and then check the height of the two holes. Because it is a distributed inspection, it leads to large errors, and the inspection is divided into two steps, resulting in low inspection efficiency. Utility Model Content
