Abstract
The invention relates to the field of product inspection, and in particular relates to a gauge for measuring a distance from the outer end surface of a workpiece to the bottom of an inner hole. The gauge is capable of rapidly and accurately measuring the distance from the outer end surface of the workpiece to the bottom of the inner hole. The gauge comprises a reference sleeve, wherein a reference block which is matched with the outer end surface of the measured workpiece is arranged at the outer end of the reference sleeve; a through groove is formed inside the reference sleeve; a slidable measuring rod is arranged inside the through groove; a spring is arranged between the measuring rod and the inner wall of the reference sleeve; the lower end of the measuring rod is connected with a measuring block which is matched with the hole of the measured workpiece; and the upper end of the measuring rod is connected with a mechanical watch.
Description
Technical field
The present invention relates to the product detection field, be 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 the 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 invention provides a kind of outside end face to endoporus distance from bottom cubing, 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 cooperates with inspection outer workpiece end face, described standard sleeve inside has groove, be provided with slidably sounding rod in the described groove, be provided with spring between described sounding rod and described standard sleeve inwall, described sounding rod lower end connects the measurement piece that cooperates with the inspection workpiece hole, and described sounding rod upper end connects stem-winder.
It is further characterized in that described stem-winder is installed on the described standard sleeve by the table cover.
After adopting structure of the present invention, the standard sleeve outer end is provided with the reference block that cooperates with inspection outer workpiece end face, standard sleeve inside has groove, be provided with slidably sounding rod in the groove, be provided with spring between sounding rod and standard sleeve inwall, the sounding rod lower end connects the measurement piece that cooperates with the inspection workpiece hole, the sounding rod upper end connects stem-winder, after positioning benchmark by the reference block that cooperates with inspection outer workpiece end face, can detect rapidly and accurately the distance of outer workpiece end face bottom the endoporus by measuring piece.
Description of drawings
Fig. 1 is structural representation of the present invention.
Embodiment
As shown in Figure 1, it comprises standard sleeve 1, standard sleeve 1 outer end is provided with the reference block 2 that cooperates with inspection workpiece 9 outside end faces, standard sleeve 1 inside has groove 3, be provided with slidably sounding rod 4 in the 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 cooperates with inspection workpiece 9 holes, sounding rod 4 upper ends connect stem-winder 7, and stem-winder 7 is installed on the standard sleeve 1 by table cover 8.
Its testing process is as described below: will measure the inside that piece 6 stretches into workpiece 9 holes, measuring piece 6 bottoms contacts with the bottom, hole, the reference block 2 of standard sleeve 1 outer end is behind positioning datum on the workpiece 9 outside end faces, make sounding rod 4 in groove 3 interior movements by spring 5 effects, change stem-winder 7 readings, stem-winder 7 readings are the distance of examining.
Claims (2)
1. an outside end face is to endoporus distance from bottom cubing, it is characterized in that, it comprises standard sleeve, described standard sleeve outer end is provided with the reference block that cooperates with inspection outer workpiece end face, described standard sleeve inside has groove, is provided with slidably sounding rod in the described groove, is provided with spring between described sounding rod and described standard sleeve inwall, described sounding rod lower end connects the measurement piece that cooperates with the inspection workpiece hole, and described sounding rod upper end connects stem-winder.
