Background technology
Metal material can form residual stress, also can produce residual stress within the service life phase of material in the machine-building processes such as casting, forging, welding.Residual stress in metallic material components in most of the cases can make the intensity of component reduce, and residual stress reduces workpiece fatigue limit, causes component stress to corrode and brittle fracture, affects the dimensional accuracy of component.Therefore, the measurement of residual stress is for guaranteeing that the safety and reliability of workpiece has very important meaning.
The measuring method of residual stress has multiple, engineering uses more general mainly Blind Hole Method, the drilling equipment application of current blind hole measuring residual stress is more is the form that support platform adds centered cover, its locate mode mainly contains two kinds: a kind of adopt the bonding feet cushion block location of glue, and this mode glue curing time is long, measured and need clear up feet cushion block and residual glue.The method complex operation, efficiency is low; Another kind of locate mode adopts permanent magnet to make platform foot rest, and the method, compared with glue fixing means, simplifies operating process, but exists due to feet magnetic force always, causes moving positioning device difficulty in operating process.
Current blind hole measuring residual stress is mainly by centering method that central cross line overlaps, monocular tube microscope is adopted to put into adapter sleeve, microscopical height is regulated to guarantee to observe strain rosette, then monocular tube microscope position is fixed with ring lock collar, again to put into microscopes observing strain rosette.Regulate the fine adjustment screw on rig floor, the central cross line of monocular tube microscope is overlapped with the central cross line of strain rosette.The method adopts monocular tube microscope, and observer need bow eyes to be attached on eyepiece and observe, and search alignment central cross line is comparatively difficult, and efficiency is low, simultaneously because visual field illumination is comparatively dark fuzzy, needs to be equipped with special lighting apparatus in addition.
Utility model content
The purpose of this utility model is for the deficiencies in the prior art, and provides a kind of boring centralising device for residual stress measurement.This device is easy and simple to handle, be easy to mobile, centering is easy to adjust, positioning time can be shortened, improve measure efficiency and measuring accuracy, cost is low.
The technical scheme realizing the object of the invention is:
For a boring centralising device for residual stress measurement, comprise supporting seat and digit microscope, also comprise
