A Chinese patent discloses a "camshaft axial dimension measuring device", and its application number is "CN201720317026.8", which includes a base, a grating scale, and a head frame mechanism, a tail frame mechanism and a measuring mechanism arranged on the base. The camshaft is installed and fixed by the head frame mechanism and the tail frame mechanism. The measuring mechanism includes an axial moving seat, a radial moving seat, a probe assembly, and a measuring mechanism. The camshaft axial dimension measuring device provided by the utility model has a simple structure. The dimensional deviation of each part of the camshaft relative to the theoretical dimension can be accurately determined by the probe, the on-off indicator module and the grating ruler. The workpiece can be replaced conveniently and quickly, and the camshaft can be tested in batches, which greatly improves the work efficiency. However, when the device clamps and fixes the camshaft, dislocation will occur, which is not conducive to the stable measurement of the device.
