Description

[Brief explanation of drawings]

FIG. 1 is an enlarged sectional view of the main part of FIG. 2, and is a diagram showing an example of an inspection state of a bottomed hole of a member to be inspected. FIG. 2 is a circuit diagram showing an example of the hole position/depth inspection device of the present invention. Figure 3 is the second
It is a diagram showing an example of use of the inspection device shown in the figure. FIG. 4 is a diagram showing another example of the inspection state by the inspection apparatus of FIG. 2, and corresponds to FIG. 1. Fifth
This figure is a diagram showing still another example of the inspection state by the inspection apparatus of FIG. 2, and corresponds to FIG. 1. FIG. 6 is a diagram showing a state in which the detection rod of the inspection device of FIG. 2 is broken, and corresponds to FIG. 1. 7 and 8 are a time chart and a flow chart for explaining the operation of the inspection apparatus shown in FIG. 2. 20: Rod (movable member), 26: Air cylinder (drive device), 36: Nozzle (movable member), 3

Claims (1)

[Claim for Utility Model Registration] Inspecting at once whether the position of a bottomed hole formed in a member to be inspected is appropriate and whether the depth of the bottomed hole is at least a predetermined certain dimension. Hole position/
The depth inspection device has an air supply port for supplying air from an air supply source to the inside, and an air discharge port for discharging the air supplied to the interior from the air supply port, and has a pre-positioned air outlet. a movable member that is provided so as to be able to approach and separate from the prepared member to be inspected approximately along the axis of the bottomed hole; and a movable member that is provided inside the movable member and is constantly biased toward the member to be inspected. As a result, the air supply port and the air discharge port are normally positioned in the closed position to prevent communication between the air supply port and the air discharge port. a valve that communicates with the air outlet and causes the air supplied to the air supply port to be discharged from the air outlet; and a valve that drives the movable member in the direction of approaching and separating from the member to be inspected, and moving the movable member in the approaching direction. a drive device that brings the movable member into contact with the member to be inspected when the valve is driven; and a drive device that is integrally provided with the valve, and in the closed position of the valve, a contact surface of the movable member with the member to be inspected. The movable member is driven by the driving device toward the member to be inspected together with the movable member, and is abutted against the peripheral edge or bottom of the bottomed hole of the member to be inspected when inserted into the bottomed hole. a detection rod that relatively drives the valve element in a direction opposite to the moving direction of the movable member to discharge the air supplied to the air supply port from the air discharge port; and air discharge detection means for detecting whether or not the air discharged from the air discharge port is detected by the air discharge detection means when the movable member is driven toward the inspected member. 1. A hole position/depth inspection device, characterized in that the formation position and depth of a bottomed hole in the member to be inspected is inspected based on whether discharge of air is detected or not.
