Abstract

The invention discloses a measurement device for rotary work pieces. The device comprises a base. A high-precision rotary table is arranged on the base. A sector wheel is also arranged on the base. A laser sensor capable of moving along the sector wheel is arranged on the sector wheel. A manipulator device is arranged on the laser sensor. The device adopts a spherical coordinate system which has high precision and high flexibility and can realize non-contact measurement in a limited space. Measurement error is avoided. Moreover, the device is simple in measurement and easy to operate.

Description

technical field [0001] The invention belongs to the technical field of measuring instruments, and relates to a measuring device for rotary workpieces. Background technique [0002] Traditional workpiece measuring devices are mostly based on geometric coordinate systems, including Cartesian coordinate systems, cylindrical coordinate systems, etc. When measuring rotary workpieces, the existing measuring device does not have high flexibility because it is a non-orthogonal coordinate measurement system. Therefore, when testing rotary workpieces, the measurement error is large and the measurement is inconvenient. Contents of the invention [0003] The object of the present invention is to provide a measuring device for rotary workpieces; the device adopts a spherical coordinate system, which has high precision and high flexibility, realizes non-contact measurement in a limited space, avoids measurement errors, and is simple in measurement and easy to operate . [0004] The pu...
