Abstract
The utility model relates to the field of product detection, in particular to a tool for detecting a distance from external end face to inner hole bottom. The tool can quickly and accurately detect the distance from the external end face to the inner hole bottom of a workpiece and comprises a reference sleeve. The outer end of the reference sleeve is provided with a reference block matched with the external end face of the workpiece, a through groove is arranged inside the reference sleeve, and a slidable measuring rod is arranged in the through groove. A spring is arranged between the measuring rod and an inner wall of the reference sleeve, the lower end of the measuring rod is connected with a measuring block matched with a workpiece hole to be detected, and the upper end of the measuring rod is connected with a mechanical watch.
Description
Technical field
The utility model relates to the product detection field, is specially a kind of outside end face to endoporus distance from bottom cubing.
Background technology
The workpiece that some are with holes, generally need to detect the degree of depth in its hole, all need to find positioning reference plane before measurement, and then measure, generally take the end face of hole opening part as reference field, some workpiece hole opening part outer end face is irregular, can't carry out origin reference location, also have some workpiece need to detect outside other end faces in hole to the distance of bottom, hole, workpiece 9 as shown in Figure 1, it need to detect other end faces of hole opening to the distance of bottom, hole, general cubing detection difficult.
Summary of the invention
In order to address the above problem, the utility model provides a kind of outside end face to endoporus distance from bottom cubing, and it can detect the outer workpiece end face rapidly and accurately to the distance of endoporus bottom.
Its technical scheme is such: it is characterized in that, it comprises standard sleeve, described standard sleeve outer end is provided with the reference block that coordinates with inspection outer workpiece end face, described standard sleeve inside has groove, be provided with slidably sounding rod in described groove, be provided with spring between described sounding rod and described standard sleeve inwall, the measurement piece that the lower end connection of described sounding rod coordinates with the inspection workpiece hole, described sounding rod upper end connection stem-winder.
It is further characterized in that, described stem-winder overlaps by table and is installed on described standard sleeve.
After adopting structure of the present utility model, the standard sleeve outer end is provided with the reference block that coordinates with inspection outer workpiece end face, standard sleeve inside has groove, be provided with slidably sounding rod in groove, be provided with spring between sounding rod and standard sleeve inwall, the sounding rod lower end connects the measurement piece that coordinates with the inspection workpiece hole, the sounding rod upper end connects stem-winder, after positioning benchmark by the reference block that coordinates with inspection outer workpiece end face, can detect rapidly and accurately the outer workpiece end face to the distance of endoporus bottom by measuring piece.
Description of drawings
Fig. 1 is the utility model structural representation.
Embodiment
As shown in Figure 1, it comprises standard sleeve 1, standard sleeve 1 outer end is provided with the reference block 2 that coordinates with the outside end face of inspection workpiece 9, standard sleeve 1 inside has groove 3, be provided with slidably sounding rod 4 in groove 3, be provided with spring 5 between sounding rod 4 and standard sleeve 1 inwall, sounding rod 4 lower ends connect the measurement piece 6 that coordinates with inspection workpiece 9 holes, sounding rod 4 upper ends connect stem-winder 7, and stem-winder 7 overlaps 8 by table and is installed on standard sleeve 1.
Its testing process is as described below: will measure the inside that piece 6 stretches into workpiece 9 holes, measurement piece 6 bottoms contact with the bottom, hole, the reference block 2 of standard sleeve 1 outer end is after positioning datum on the outside end face of workpiece 9, make sounding rod 4 in the interior movement of groove 3 by spring 5 effects, change stem-winder 7 readings, stem-winder 7 readings are the distance of examining.
