Calibration device for runout, roundness and size of optical thin-walled long shaft sleeve

Abstract

The invention relates to a verifying device for jumping, roundness and dimension of an optical thin-wall long shaft sleeve. A vertical plate is vertically fixed on the base; an installation hole and two guide holes are formed in the vertical plate; an inner tension verifying core shaft structure comprises an inner tension core shaft and an adjustable taper screw; one end of the inner tension core shaft is arranged in the installation hole of the vertical plate; a cylinder with a tension cut is arranged at the other end of the inner tension core shaft; the adjustable taper screw penetrates through the cylinder in an axial direction and is screwed into an inner threaded hole of the inner tension core shaft; an outer contraction verifying regulating structure comprises a movable plastic spacer bush and a fine turning nut, wherein the movable plastic spacer bush sleeves each guide hole of the vertical plate; a threaded hole is formed in the vertical plate opposite to the guide hole in the radial direction; the fine turning nut is screwed into the threaded hole and propped against the outer edge surface of the movable plastic spacer bush. The verifying device can be used for performing manual fine-turning correcting repair on roundness / cylindrical degree / inner and outer dimensions of the optical thin-wall long shaft sleeve product, so that the optical thin-wall long shaft sleeve product meets the dimension and form and location tolerance needs of the components again.

Description

technical field [0001] The invention relates to a device for verifying the runout, roundness and size of an optical thin-walled long shaft sleeve. Background technique [0002] At present, after the processing of optical thin-walled parts, it will be found that the roundness and cylindricity are deformed and cannot meet the requirements of the drawings, and effective verification and repair cannot be carried out, so they can only be scrapped. A lot of financial and material resources were wasted, seriously restricting the smooth progress of the production schedule. Contents of the invention [0003] The purpose of the present invention is to overcome the deficiencies in the prior art and provide a calibration device for the runout, roundness and size of the optical thin-walled long shaft sleeve. [0004] The purpose of the present invention is achieved through the following technical solutions: [0005] The optical thin-walled long shaft sleeve runout, roundness and size...
