Abstract
A kind of tool locating concentric shafts, comprise positioning shaft, non-locating axle and boss, described positioning shaft is 3 sections, and be non-locating axle between every two sections of positioning shafts, described boss is positioned at the two ends of concentric shafts.The utility model structure is simple, effectively can reduce the surface friction drag that axle is suffered when inserting and take out, easy to use, and the design of boss can avoid concentric shafts direct stress deformation of positioning shaft when inserting and take out, and therefore can effectively extend its working life.
Description
Technical field
The utility model relates to mechanical structure technical field, is specifically related to a kind of tool locating concentric shafts.
Background technique
Along with the development of assembly technology, people more and more recognize assembly technology significance aborning.The revolving structure required for there being coaxality, if the validity of its coaxality effectively can not be ensured, that can bring its usability and working life and have a strong impact on, so tool locating concentric shafts application aborning is now more and more extensive, but existing tool locating concentric shafts suffered surface friction drag when inserting and take out is larger, be not easy to use, and yielding, working life is short.
Model utility content
The purpose of this utility model is for above-mentioned deficiency of the prior art, provides a kind of tool locating concentric shafts.
The technical solution of the utility model is:
A kind of tool locating concentric shafts, this concentric shafts comprises positioning shaft, non-locating axle and boss, and described positioning shaft is 3 sections, and be non-locating axle between every two sections of positioning shafts, described boss is positioned at the two ends of concentric shafts.
The beneficial effects of the utility model are: the utility model structure is simple, effectively can reduce the surface friction drag that axle is suffered when inserting and take out, easy to use, and the design of boss can avoid concentric shafts direct stress deformation of positioning shaft when inserting and take out, and therefore can effectively extend its working life.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Embodiment
Do to disclose further to the utility model below in conjunction with accompanying drawing.
Embodiment
As Fig. 1 shows, a kind of tool locating concentric shafts, this concentric shafts comprises positioning shaft 1, non-locating axle 2 and boss 3, and described positioning shaft 1 is 3 sections, and be non-locating axle 2 between every two sections of positioning shafts 1, described boss 3 is positioned at the two ends of concentric shafts.
During use, first concentric shafts one end is inserted in tool locating seat, knock outside boss 3 gently, allow the forefront localization part of concentric shafts slowly enter in workpiece hole; Workpiece is welded in frock well, knock boss 3 from inner side, allow concentric shafts slowly take out, then workpiece is carried out turning sequence.
Claims (1)
