Abstract

The invention relates to the field of product detecting, in particular to a through hole depth gauge. The through hole depth gauge can fast and accurately detect whether through hole depth accords to specification or not and comprises a benchmark block. A floatable measuring block is disposed inside the lower end of the benchmark block. The upper end of the measuring block is connected with a mechanical watch. A spring is disposed between the measuring block and the upper end inner wall of the benchmark block. A spherical measuring head matched with a pore at the bottom of a to-be-detected workpiece is disposed at the bottom of the measuring block. A detachable calibration member is disposed at the lower end of the benchmark block.

Description

A kind of via depth cubing
Technical field
The present invention relates to the product detection field, be specially a kind of via depth cubing.
Background technology
Some are with the workpiece of through hole, the step that the different-diameter size is generally arranged in its hole, sometimes need to detect the bottom surface, somewhere to the distance of step, it is the degree of depth of through hole, because on the workpiece is through hole, measurer can be stretched in the through hole when larger in the aperture and directly measure, when the bottom surface is an aperture, then can't deeply detect it.
Summary of the invention
In order to address the above problem, the invention provides a kind of via depth cubing, whether its degree of depth that can detect fast and accurately through hole is up to specification.
Its technical scheme is such: it is characterized in that, it comprises reference seat, inside, described reference seat lower end is provided with relocatable measurement piece, described measurement piece upper end connects stem-winder, be provided with spring between described measurement piece and described reference seat upper end inwall, described measurement piece bottom is provided with the spherical measuring head that cooperates with inspection workpiece small hole at bottom part, and described reference seat lower end is provided with dismountable calibrating device.
It is further characterized in that described stem-winder is installed on the described reference seat by gauge stand.
After adopting structure of the present invention, inside, reference seat lower end is provided with relocatable measurement piece, measure the piece upper end and connect stem-winder, measure between the inwall of piece and reference seat upper end and be provided with spring, measure the piece bottom and be provided with the spherical measuring head that cooperates with inspection workpiece small hole at bottom part, the reference seat lower end is provided with dismountable calibrating device, by whether up to specification by measuring spherical measuring head on the piece behind the reference seat location if detecting fast and accurately the degree of depth of through hole.
Description of drawings
Fig. 1 is structural front view of the present invention;
Fig. 2 is the calibrating device synoptic diagram.
Embodiment
See Fig. 1, shown in Figure 2, it comprises reference seat 1, inside, reference seat 1 lower end is provided with relocatable measurement piece 2, measure piece 2 upper ends and connect stem-winder 3, measure between piece 2 and reference seat 1 upper end inwall and be provided with spring 4, measure piece 2 bottoms and be provided with the spherical measuring head 5 that cooperates with inspection workpiece 8 small hole at bottom parts, reference seat 1 lower end is provided with dismountable calibrating device 6, and stem-winder 3 is installed on the reference seat 1 by gauge stand 7.
Its testing process is as described below: first calibrating device 6 is positioned over reference seat 1 lower end, stem-winder 3 is calibrated, then inspection workpiece 8 is positioned on the level table, again reference seat 1 after taking away, calibrating device 6 is positioned in the through hole of the workpiece of examining 8, after positioning benchmark by reference seat 1, the spherical measuring head 5 of measuring on the piece 2 stretches in the institute's workpiece of examining 8 small hole at bottom parts, contacts with level table, and the reading of stem-winder 3 is the degree of depth of through hole at this moment.

Claims (2)
