Size inspection device

Abstract

A size inspection device includes a detecting platform, a positioning assembly, four first detecting assemblies, four second detecting assemblies, a third detecting assembly, and a controller. The detecting platform includes a mounting plate. The positioning assembly is detachably mounted on the mounting plate for holding the workpiece on the detecting platform. The controller is electronically connected to the first detecting assemblies, the second detecting assemblies, and the third detecting assembly. The four first detecting assemblies and the four second detecting assemblies are slidably mounted on the mounting plate and are capable of obtaining a first moving distance and a second moving distance respectively. The third detecting assembly is mounted on the mounting plate and is capable of obtaining a third moving distance. The controller obtains the moving distances and determines whether or not the workpiece is of passing or failing quality.
