MEASURING DEVICE

摘要

Measuring device for measuring a rotationally symmetrical cavity in a workpiece has a base body for supporting on the workpiece, and a measuring head with a sensor for scanning the inner wall of the cavity. The measuring device has a shaft connected to the base body. Measuring head is movable relative to base body in the axial direction of the shaft and is rotatable about a rotational axis defined by the shaft. The shaft is configured as a hollow shaft, and accommodates a drive shaft rotationally drivable by a rotary drive apparatus. A distal end of the drive shaft is connected to the measuring head in a rotationally fixed manner. The shaft is situated on the base body and movable in the axial direction of the shaft by a slide bearing system. An axial drive apparatus moves the shaft relative to the base body.

主权项

1. A measuring device for measuring a rotationally symmetrical cavity in a workpiece, the device comprising:
a) a base body provided for supporting on the workpiece; b) a measuring head provided and having at least one sensor for scanning an inner wall of the cavity; c) a shaft connected to the base body, the measuring head being movable relative to the base body in an axial direction of the shaft and rotatable about a rotational axis defined by the shaft; and d) the shaft being configured as a hollow shaft, and accommodates a drive shaft which is rotationally drivable by a rotary drive apparatus, a distal end of the drive shaft being connected to the measuring head in a rotationally fixed manner, and the shaft is situated on the base body so as to be movable in the axial direction of the shaft by means of a slide bearing system, and an axial drive apparatus being provided for moving the shaft relative to the base body.
