Technical Field
The utility model belongs to the field of inspection and measurement, and particularly relates to a device for measuring verticality of a part.
Background
When detecting verticality, the machined part or assembly needs to be measured by attaching a measured element of the verticality of the part to a standard square box relative to a reference and clamping, and then rotating for 90 degrees; or with a three-coordinate measuring machine.
When the standard square box is used for measurement, clamping and alignment are laborious, and the method is inconvenient especially for larger and heavier parts, and the risk of pressing hands or the risk of collision of the parts with the surface of the marble platform is caused in the measurement process; the clamping damage can be caused to the parts in the clamping process; the heavier parts are affected by gravity and have problems of clamping errors, accumulated errors and the like.
When the three-coordinate measuring machine is used for measuring, a large and heavy part is not easy to move to a platform of the three-coordinate measuring machine; the point taking can be limited in the measuring process, for example, the angle of a probe is limited or the relative position of a measured element of the part is small, and a dead angle exists.
