Abstract
The utility model relates to the field of product detection, in particular to a bolt go-no go gauge. The bolt go-no go gauge can rapidly and accurately detect whether smooth length of a screw on a bolt meets specifications or not. The bolt go-no go gauge comprises a base and is characterized in that a movable standard seat is arranged on the base, a location hole matched with the screw with threads on the bolt to be detected is arranged on the standard seat, a go-no go detection seat is respectively arranged at two ends of the standard seat, and an upper surface of the go-no go detection seat is matched with the bottom end of the head of the detected bolt.
Description
Technical field
The utility model relates to the product detection field, is specially a kind of bolt go-no go gauge.
Background technology
Bolt is very common part in life, the general cooperation with nut of bolt played fixation, some bolts are comprised of one section threaded screw rod, one section smooth screw rod and bolt head, smooth screw rod generally has certain length specification, conventional survey instrument can't directly be measured its length, need to carry out areal survey, because bolt head is generally irregularly shapedly, easily produce larger measuring error in measuring process.
Summary of the invention
In order to address the above problem, the utility model provides a kind of bolt go-no go gauge, and whether its spiro rod length that can detect rapidly and accurately the bolt Smooth is up to specification.
Its technical scheme is such: it comprises base, it is characterized in that, be provided with movably reference seat on described base, be provided with the pilot hole that coordinates with threaded screw rod on tested bolt on described reference seat, described reference seat two ends are respectively arranged with the logical seat that only detects, and the described logical bottom of only detecting seat upper surface and the bolt head of examining coordinates.
It is further characterized in that, is provided with chute on described base, is provided with described reference seat in described chute.
After adopting structure of the present utility model, be provided with movably reference seat on base, be provided with the pilot hole that coordinates with threaded screw rod on tested bolt on reference seat, the reference seat two ends arrange respectively the logical seat that only detects, the logical bottom of only detecting seat upper surface and finding bolt head coordinates, tested bolt is positioned on reference seat, and whether the spiro rod length that can detect rapidly and accurately the bolt Smooth by the moving reference seat is up to specification.
Description of drawings
Fig. 1 is the utility model structural representation.
Embodiment
As shown in Figure 1, it comprises base 1, be provided with movably reference seat 2 on base 1, be provided with the pilot hole 3 that coordinates with threaded screw rod on tested bolt 7 on reference seat 2, reference seat 2 two ends are respectively arranged with the logical seat 4,5 that only detects, the logical bottom cooperation that only detects seat 4,5 upper surfaces and the institute's bolt of examining 7 heads is provided with chute 6 on base 1, be provided with reference seat 2 in chute 6.
Its testing process is as described below: threaded screw rod on institute's inspection bolt 7 is aimed at pilot hole 3 insert, by 2 pairs of reference seat the bolt of examining 7 positioning datums, then detect seat 4 to leading to respectively, stop and detect 5 a moving reference seat 2, if the bottom of bolt 7 heads can be detected seat 4 and can not detect seat 5 by stopping by logical, up to specification, if the bottom of bolt 7 heads can not be by the logical seat 4 that detects, illustrate that smooth spiro rod length is too short, if the bottom of bolt 7 heads can by only detecting seat 5, illustrate that smooth spiro rod length is long.
Claims (2)
1. bolt go-no go gauge, it comprises base, it is characterized in that, be provided with movably reference seat on described base, be provided with the pilot hole that coordinates with threaded screw rod on tested bolt on described reference seat, described reference seat two ends are respectively arranged with the logical seat that only detects, and the described logical bottom of only detecting seat upper surface and the bolt head of examining coordinates.
