Abstract

The invention belongs to the technical field of precision machinery, and discloses a coaxiality and gap measuring device for frame components, which includes a force applying unit, a workbench unit, a gap measuring unit and a coaxiality visual measuring unit. The coaxiality of the frame assembly of the frame assembly can be measured by the coaxiality visual measurement unit, and the force-applying probe is driven by the sliding table of the force-applying unit to move the force-applying probe within the specified force range to the frame assembly fixed on the workbench unit. Apply force, then measure the tiny displacement of the surface corresponding to the point of force application through the gap unit to determine the assembly gap, and check whether the coaxiality and gap meet the assembly requirements.

Description

technical field [0001] The invention belongs to the technical field of precision machinery and relates to the measurement of the coaxiality of frame components and the assembly gap, which can accurately measure the assembly gap, detect the assembly quality, and provide a basis for the assembly and adjustment of subsequent parts. Background technique [0002] The frame assembly involved in the present invention belongs to the field of precision machinery, and two circular ring parts of the frame assembly are assembled by connecting screws. Due to the fit gap between the thread pairs, the gap between the two ring parts of the frame assembly changes under the action of external force, which affects the coaxiality of the assembly. Therefore, when performing automatic assembly of frame components, it is necessary to ensure that the maximum displacement of the assembly gap meets the assembly requirements when a certain force is applied. Therefore, when assembling such components, ...
