Embodiment Construction
[0023] The orientation words such as "transverse direction", "axial direction" and "vertical direction" involved in this application are described in the directions shown in the drawings. It can be understood that the description of the above orientation words is to clearly indicate the relative positional relationship of the technical solution of the present application, and the placement and arrangement of the products carrying the technical solution of the present application may not be limited to the orientation relationship shown in the drawings of this application , so the above orientation words do not limit the protection scope of the present application.
[0024] When measuring the dimensional parameters of shaft parts, the traditional manual measurement method is inefficient, and due to the instability of manual operation, the measurement accuracy is limited; while automatic measurement has high measurement efficiency, but the same shaft The measurement of different ...

The present application discloses a diameter measuring device, which comprises: a frame on which a support rod is installed, and the support rod is used for positioning and supporting the surface of the workpiece to be measured in the measurement state; at least two first elastic The measuring unit is installed on the frame and arranged symmetrically on both sides of the support rod at intervals. The first elastic measuring unit includes a first measuring end, which is used to elastically interfere with the target section of the workpiece to be measured in the measuring state, so as to measure the Dimensional parameters of the target section; the second elastic measuring unit is fixed on the first measuring end, the second elastic measuring unit includes a second measuring end, and the second measuring end is spaced apart from the first measuring end in the axial direction of the workpiece to be measured , which is used to measure the difference in size parameters between other sections of the workpiece to be tested and the target section. According to the technical solution of the present application, a measuring device for shaft workpieces is provided which is simple in operation, high in applicability and high in measuring efficiency.
Description
technical field [0001] The present application relates to the field of measurement, and more specifically, relates to a diameter measuring device for shaft workpieces. Background technique [0002] Shaft workpieces are widely used in the industrial field. In order to ensure the good performance of shaft parts in practical applications, it is usually necessary to measure the diameter, roundness, cylindricity, taper and other parameters of shaft workpieces before equipment assembly. [0003] The measurement methods traditionally used for shaft workpieces mainly include manual measurement and automatic measurement. Among them, on the one hand, the manual measurement performed by traditional measurement tools has low measurement efficiency, and on the other hand, errors are prone to occur during manual operation, resulting in a decrease in measurement accuracy. The automated measurement method is usually suitable for the measurement of a large number of parts. Often only a cert...
