The invention discloses an arm-variable articulated coordinate measuring machine and relates to the technical field of coordinate measuring machines. The arm-variable articulated coordinate measuring machine comprises a measuring arm, wherein two ends of the measuring arm are respectively in articulated connection with a measuring head and a base measuring arm; the base measuring arm is mounted on a base; the measuring arm comprises a first fixed arm, a movable arm and a second fixed arm which are sequentially connected with one another; one end of the movable arm sleeves the exterior of the first fixed arm; the movable arm is in threaded connection with the first fixed arm; the other end of the movable arm is connected with one end of the second fixed arm by virtue of a bolt. Compared with the prior art, the arm length of the measuring arm is adjustable; the application range of the measuring machine can be widened; when the arm-variable articulated coordinate measuring machine is used for measuring small-sized parts, the arm length is regulated and the size of the measuring space is reduced, so that the measurement accuracy of the small-sized parts can be improved.
Description
technical field [0001] The invention relates to the technical field of coordinate measuring machines, in particular to a variable-arm articulated coordinate measuring machine. Background technique [0002] The articulated coordinate measuring machine is a non-orthogonal coordinate measuring instrument. Compared with the traditional orthogonal coordinate measuring machine, it has a space series structure, so it has a large degree of freedom, a wide measurement space, flexible and convenient operation, and is suitable for on-site measurement. Features. However, the measuring arms of the existing articulated coordinate measuring machines are all fixed arm lengths. When the variable arm articulated coordinate measuring machine with this structure is used to measure small-sized parts, the measurement space is often much larger than the measured parts , which results in redundant measurement space and reduces the measurement accuracy; this structure of immutable arm length greatl...
