Abstract
The utility model discloses a depth detector for a counter bore, comprising two sections, an upper section and a lower section, wherein the lower section is cylindrical; the designed diameter of the counter bore is the same as the external diameter; the height of the lower section is the same as the designed depth of the counter bore; the upper section is also cylindrical; the external diameter of the upper section is greater than the designed depth of the counter bore; the upper and lower sections are coaxially arranged; and a through hole passes through the upper and lower sections. The depth detector for a counter bore can quickly and accurately detect whether the size parameter is qualified and is low in cost.
Description
Technical field
The utility model belongs to the machine tool technical field, relates in particular to a kind of counterbore depth detection apparatus.
Background technology
Counterbore processing is the common step in the machinery production process, and whether the dimensional parameters of counterbore reaches the quality that designing requirement has directly determined engineering goods, and size how to measure counterbore has quickly and accurately then become a focal issue.Mostly present most of machinery production enterprise is to rely on the measurement of conventional tool such as visual observation and vernier caliper to judge whether tested counterbore is qualified by the skilled labor; This mode measuring speed is very slow; Improved the cost of enterprise thereby need a large amount of skilled workmans to finish the work, and this mode still there is the not enough phenomenon of accuracy.
Summary of the invention
The utility model aims to provide a kind of counterbore depth detection apparatus, and whether can detect the dimensional parameters that draws tested counterbore quickly and accurately qualified.
For this reason, the technical scheme of the utility model is such: the counterbore depth detection apparatus, and described counterbore depth detection apparatus is divided into two sections, and hypomere is a cylindrical shape, and external diameter is identical with the intended diameter of counterbore, and the height of hypomere is identical with the projected depth of counterbore; Epimere also is a cylindrical shape, and the external diameter of epimere is greater than the projected depth of counterbore; Two sections are coaxial; Other has a through hole to run through two sections.
When detecting counterbore, attempt the hypomere of counterbore depth detection apparatus is inserted tested counterbore, explain that then this counterbore is defective if can't the hypomere of counterbore depth detection apparatus be inserted tested counterbore.After the hypomere of counterbore depth detection apparatus inserted tested counterbore; The counterbore depth detection apparatus is shaken in trial; And through the through hole on the counterbore depth detection apparatus with visual observation or with instrument, finger touch; Whether hypomere and the tested counterbore of judging the counterbore depth detection apparatus fits tight, if the amplitude that the counterbore depth detection apparatus can shake is excessive or counterbore depth detection apparatus and counterbore between excesssive gap, then this counterbore is defective.
Whether the utility model can detect the dimensional parameters that draws tested counterbore quickly and accurately qualified, and cost is very low, alleviated the cost pressure of flat machine manufacturing enterprise, can improve economic benefit of enterprises greatly.

Fig. 2 uses synoptic diagram for the utility model.
Embodiment
Referring to accompanying drawing, counterbore depth detection apparatus 1 is divided into epimere 2 and hypomere 3, and hypomere 3 is a cylindrical shape, and external diameter is identical with the intended diameter of tested counterbore 4, and the height of hypomere 3 is identical with the projected depth of tested counterbore 4.Epimere 2 also is a cylindrical shape, and the external diameter of epimere 2 is greater than the projected depth of tested counterbore 4.Counterbore depth detection apparatus 1 also has through hole 5.
When detecting counterbore; Hypomere 3 is inserted tested counterbore 4; Counterbore depth detection apparatus 1 is shaken in trial, and through through hole 5 usefulness visual observation or with instrument, finger touch, judges whether tight hypomere 3 and tested counterbore 4 fit; If the amplitude that can shake of counterbore depth detection apparatus 1 is excessive or the excesssive gap of 4 of counterbore depth detection apparatus 1 and tested counterbores, then this tested counterbore 4 is defective.
