This utility model belongs to the field of virtual thickness measurement, specifically relating to a virtual thickness measuring device, including a measuring rod, a scale tube, a calibration sleeve, and two storage rods. The measuring rod passes through the scale tube, and the calibration sleeve is slidably connected to the scale tube. The length of the scale tube is greater than the length of the measuring rod. Multiple connecting through holes are provided on the measuring rod along its axial direction. A conical head is provided at the lower end of the measuring rod. A connecting ring is provided at the upper part of the scale tube, and two oppositely arranged storage holes are provided on the connecting ring. When the measuring rod is in the storage state, the two storage rods are respectively connected one-to-one in the two storage holes, and the two storage rods pass through the connecting through holes and cooperate. At this time, the conical head is located inside the scale tube. In the storage state, the conical head is located inside the scale tube to avoid safety hazards.

The application relates to the technical field of detection devices, and provides a fixed block automatic detection device which comprises a mounting frame, a carrier, a first detection mechanism, a first driving mechanism, a second detection mechanism and a second driving mechanism. The carrier is located at the side of the mounting frame, the first detection mechanism is located at the side of the carrier, the first driving mechanism drives the first detection mechanism to approach or move away from the carrier, the second detection mechanism is located above the carrier, and the second driving mechanism drives the second detection mechanism to approach or move away from the carrier. The fixed block automatic detection device provided by the application uses machinery to replace manual work to perform quality inspection on the fixed block. After manual work places the fixed block on the carrier, the first driving mechanism drives the first detection mechanism to approach the carrier, the first detection mechanism detects the holes in the side of the fixed block, the second driving mechanism drives the second detection mechanism to approach the carrier, and the second detection mechanism detects the holes in the upper end of the fixed block. The detection process is automatically completed by the equipment, and the quality inspection work efficiency and quality inspection quality of the fixed block are improved.

A method and a tool for performing a dimensional inspection on a vane ring, comprises referencing an inspection tool relative to a vane of the vane ring to aim a measuring tool, such as a caliper, at predetermined spanwise and chordwise coordinates along the vane. Once the inspection has been properly positioned on the vane, the measuring tool is used to measure a dimensional parameter, such as a vane thickness, at a location corresponding to the predetermined spanwise and chordwise coordinates. Then, the operator determines if the measured dimensional parameter is within acceptable tolerance limits.

This utility model discloses a simple device for measuring the thickness of precision mechanical parts, relating to the field of precision mechanical parts inspection. The device includes a caliper with an inner wall measuring unit on one side. The inner wall measuring unit includes a sleeve, a rotating post, and a threaded post. The sleeve is movably engaged with one side of the caliper; the rotating post is rotatably connected to the sleeve; and the threaded post is rotatably connected inside the rotating post, with the threaded post threadedly engaged with the rotating post. This device, by setting the inner wall measuring unit on one side of the caliper and using the sleeve to movably engage the inner wall measuring unit with the caliper, allows for position adjustment according to measurement needs. The rotating post can rotate relative to the sleeve, facilitating adjustment of the measuring angle to accommodate different internal structures of irregularly shaped parts. The threaded post is threadedly engaged with the rotating post; rotating the threaded post changes its extension length beyond the rotating post, allowing it to contact the inner top of irregularly shaped parts such as curved blocks, thus achieving accurate thickness measurement.
