Abstract
The utility model relates to the field of production detection and particularly relates to a through hole depth detection tool which is capable of quickly and accurately detecting whether through hole depth meets specifications or not. The through hole depth detection tool comprises a reference seat. A measuring block capable of floating is arranged in the lower end of the reference seat, the upper end of the measuring block is connected with a mechanical meter, a spring is arranged between the measuring block and the upper end inner wall of the reference seat, a spherical measuring head matched with a small hole at the bottom of the work piece to be detected is arranged at the bottom of the measuring block, and a detachable correction piece is arranged at the lower end of the reference seat.
Description
Technical field
The utility model relates to the product detection field, is specially a kind of via depth cubing.
Background technology
Some are with the workpiece of through hole, the step of 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, owing to being through hole on workpiece, measurer can be stretched in through hole when larger in the aperture and directly measure, when the bottom surface is an aperture, can't deeply detect it.
Summary of the invention
In order to address the above problem, the utility model provides a kind of via depth cubing, and 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 coordinates 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 described reference seat by gauge stand.
After adopting structure of the present utility model, inside, reference seat lower end is provided with relocatable measurement piece, measure piece upper end connection stem-winder, measure between piece and reference seat upper end inwall and be provided with spring, measurement piece bottom is provided with the spherical measuring head that coordinates with inspection workpiece small hole at bottom part, the reference seat lower end is provided with dismountable calibrating device, by behind reference seat location, whether up to specification by measuring spherical measuring head on piece if detecting fast and accurately the degree of depth of through hole.
Description of drawings
Fig. 1 is the utility model structural front view;
Fig. 2 is the calibrating device schematic diagram.
Embodiment
See Fig. 1, shown in Figure 2, it comprises reference seat 1, reference seat 1 inside, lower end is provided with relocatable measurement piece 2, measure piece 2 upper ends and connect stem-winders 3, measure between piece 2 and reference seat 1 upper end inwall and be provided with spring 4, measurement piece 2 bottoms are provided with the spherical measuring head 5 that coordinates 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 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 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 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)
