Manual inner wall holding device and method of thin wall cylindrical component

Abstract

The invention discloses a manual wall holding device and method of a thin wall (10-200 microns) cylindrical component. The device comprises a base 1, a left fixed seat 2, a silicone pad 3, a micro force sensor 4, a mobile holding end 5, a fixed holding end 6, a right fixed seat 7, a differential micrometer head fixed seat 8, a differential micrometer head 9, a support shaft A10, a support shaft B11 and a support pillar 12. The device and the method finish the holding action of component through the differential micrometer head based on a micro-vision image and holding feedback force information. A micro-vision camera is arranged above the mobile holding end and the fixed holding end in a holding process, the mobile holding end is controlled close to the component according to the micro-vision image; the acting force is sensed through the micro force sensor after the mobile holding end is contacted with the inner wall of a held component; and the mobile holding end is adjusted to move according to the acting force so as to realize the purpose of no-wear holding of the component.

Description

technical field [0001] The invention relates to the technical field of precision assembly, in particular to a device and method for manually clamping the inner wall of a thin-walled cylindrical part. Background technique [0002] There is a type of thin-walled cylindrical parts in the field of precision assembly. The outer wall of the part needs to be in contact with other parts during assembly, so a clamping device is required to clamp the part from the inner wall; after the parts are assembled, the clamping device should be able to be taken out of the part smoothly . Since such parts are thin-walled (usually with a wall thickness of 10-1000 microns), the traditional clamping device or method cannot meet the precision assembly requirements in terms of clamping displacement and clamping force control, and the parts are easily damaged during the clamping process. Therefore, there is an urgent need for a new type of clamping device and method based on microscopic vision and f...

Since such parts are thin-walled (usually with a wall thickness of 10-1000 microns), traditional clamping devices or methods cannot meet the precision assembly requirements in terms of clamping displacement and clamping force control, and the parts are easily damaged during the clamping process. Therefore, there is an urgent need for a new type of clamping device and method based on microscopic vision and force sense control to achieve non-destructive clamping of parts.
