Abstract:
1. A size inspection device for detecting and inspecting sizes of a workpiece with a receiving groove automatically, comprising: a detecting platform comprising a mounting plate; a positioning assembly detachably mounted on the mounting plate for holding the workpiece on the detecting platform; at least one first detecting assembly; at least one second detecting assembly; at least one third detecting assembly; and a controller electrically connected to the at least one first detecting assembly, the at least one second detecting assembly, and the at least one third detecting assembly; wherein the at least one first detecting assembly, and the at least one second detecting assembly are slidably mounted on the mounting plate surrounding the positioning assembly, a sliding direction of the at least one first detecting assembly is perpendicular to a sliding direction of the at least one second detecting assembly, the at least one first detecting assembly and the at least one second detecting assembly are capable of moving toward the positioning assembly and resisting corresponding sidewalls of the workpiece, thereby obtaining a first moving distance and a second moving distance, respectively, the at least one first detecting assembly and the at least one second detecting assembly send the first and the second moving distances to the controller, the at least one third detecting assembly is mounted on the mounting plate opposite to the positioning assembly, and capable of moving through the mounting plate and resisting a bottom of the workpiece and a bottom of the receiving groove, thereby obtaining a third moving distance between the bottom wall and the bottom of the receiving groove, the at least one third detecting assembly sends the third moving distance to the controller, the controller compares the first, the second, and the third moving distances to preset standard value ranges, to determine whether the size measurements of the workpiece have passed or failed size inspection.
