Abstract

The invention provides a measuring tool, which relates to the general technical field of machinery, and includes at least two measuring modules. The measuring module includes a first measuring unit and a second measuring unit, and the second measuring unit is attached to the first measuring unit. The measuring tool provided by the embodiment of the present invention can conveniently and quickly measure the coaxiality error and parallelism error of the inner hole of the workpiece under the premise of ensuring the accuracy.

Description

technical field [0001] The invention relates to the general technical field of machinery, in particular to a measuring tool. Background technique [0002] Coaxiality error and parallelism error are important parameters for evaluating workpieces in industrial manufacturing. There are many methods for measuring coaxiality error and parallelism error in the prior art, but they are all used for outer circle coaxiality error and parallelism. There are not many measurement tools for the coaxiality error and parallelism error of the inner hole, and it is not easy to use. Contents of the invention [0003] The invention solves the problem that the measuring tool for measuring the coaxiality error and parallelism error of the inner hole is inconvenient to use. [0004] In order to solve the above problems, an embodiment of the present invention provides a measuring tool, which includes at least two measuring modules; the measuring module includes a first measuring unit and a secon...
