Once detect simultaneously the go side in hole and the feeler gauge of not-go-end
Technical field
The present invention relates to a kind of feeler gauge.
Background technology
The feeler gauge that detects at present the hole is mostly to form according to go side A, not-go-end B and bar C.Go side and not-go-end will manufacture two parts, and a hole will be detected respectively twice.Numerous and diverse owing to detecting, use inconvenient.Because feeler gauge easily weares and teares.Feeler gauge is difficult for long-term the use, is difficult for universal.Factory mostly just inspects by random samples with putting in storage before afterwards in parts batch processing.Can not detect by part.
Summary of the invention
The purpose of this invention is to provide a kind of go side in hole and feeler gauge of not-go-end of once detecting simultaneously, when detecting to solve present feeler gauge operation comparatively numerous and diverse, use the problem popularized of being unfavorable for inconvenient and easy to wear.
The present invention solves the problems of the technologies described above the technical scheme of taking to be: test section is provided with go side tapering transition section, go side, not-go-end tapering transition section and not-go-end successively, and go side tapering transition section, go side, not-go-end tapering transition section are connected with not-go-end makes one.
The present invention has following beneficial effect: the same position of closing on of testing tool of the present invention all was provided with end, mistake end tapering transitioning end and not-go-end, not-go-end tapering transition section, and cross end, mistake end tapering transitioning end, not-go-end and not-go-end tapering transition section, be made as one, cross end and not-go-end front end and increased the tapering transitioning end, large end is maximum limit of size, small end is the minimum limit of size, penetrate easily, easy to use.Be not easy wearing and tearing, the serviceable life of having improved feeler gauge.A hole is as long as detect once just passable.Use feeler gauge of the present invention can realize that mass detects.

Embodiment
Embodiment one: present embodiment is described in conjunction with Fig. 1, the test section of present embodiment is provided with go side tapering transition section 1-3, go side 1-1, not-go-end tapering transition section 1-4 and not-go-end 1-2 successively, and go side tapering transition section 1-3, go side 1-1, not-go-end tapering transition section 1-4 are connected with not-go-end 1-2 and make one.
Embodiment two: present embodiment is described in conjunction with Fig. 1, the go side tapering transition section 1-3 of present embodiment and not-go-end tapering transition section 1-4 are truncated cone-shaped, go side tapering transition section 1-3 is that larger diameter end and this end are identical with the diameter of go side 1-1 near the termination of go side 1-1, the smaller diameter end of not-go-end tapering transition section 1-4 is identical with the diameter of go side 1-1, the larger diameter end of not-go-end tapering transition section 1-4 is identical with the diameter of not-go-end 1-2, prevent the feeler gauge wearing and tearing, increase the service life.Other embodiment is identical with embodiment one.
Embodiment three: in conjunction with Fig. 1, present embodiment is described, is provided with the first undercut 1-5 between the go side tapering transition section 1-3 of present embodiment and go side 1-1, easily process and differentiate go side 1-1 and go side tapering transition section 1-3.Other embodiment is identical with embodiment one.
Embodiment four: in conjunction with Fig. 1, present embodiment is described, is provided with the second undercut 1-6 between the go side 1-1 of present embodiment and not-go-end tapering transition section 1-4.Easily process and differentiate go side 1-1 and not-go-end tapering transition section 1-4.Other embodiment is identical with embodiment one.
Embodiment five: in conjunction with Fig. 1, present embodiment is described, is provided with the 3rd undercut 1-7 between the not-go-end tapering transition section 1-4 of present embodiment and not-go-end 1-2.Easily process and differentiate not-go-end tapering transition section 1-4 and not-go-end 1-2.Other embodiment is identical with embodiment one.
Principle of work: when detecting the hole.Test section is passed processing later hole, and go side tapering transition section 1-3 and go side 1-1 pass, and stop at not-go-end tapering transition section 1-4 and not-go-end 1-2 place.Be qualified hole.This detection method and testing tool can detect respectively the hole that coordinates with axle.Qualified workpiece mostly contacts and rests on not-go-end tapering transition section 1-4, defective workpiece mostly contacts and rest on tapering transition section 1-3 place, go side, has reduced contacting and wearing and tearing of not-go-end 1-2 and go side 1-1 and workpiece, thus the serviceable life of having improved feeler gauge.
