Abstract
Specific pressure and temperature conditions of an engine being measured are achieved by a compressor and a coolant controller, and bore distortion is measured as a gap between a rotation unit and a cylinder wall, wherein the measuring position may be vertically and angularly varied.
Claims15
An apparatus for measuring bore distortion of a cylinder block, comprising:
- a compressor for applying pressure to a bore of the cylinder block;
- a coolant controller for controlling the temperature of a coolant supply to the cylinder block for temperature control of the cylinder block;
- a slider unit mounted in the cylinder block, the slider unit being movable along a longitudinal direction of the cylinder block;
- a first driving unit for moving the slider unit along the longitudinal direction of the cylinder block;
- a rotation unit rotatably mounted to an end of the slider unit;
- a second driving unit for rotating the rotation unit;
- at least one first sensor laterally mounted to the rotation unit, for detecting a clearance between the bore and the rotation unit;
- and
- a second sensor for detecting the longitudinal position of the slider unit.
