Abstract

The utility model relates to an exchangeable measuring-rod type small-bore groove depth measuring tool which comprises a ruler body, a measuring rod, a spring, a rear cover and a measuring rod seat. The exchangeable measuring-rod type small-bore groove depth measuring tool is characterized in that a through hole is arranged at the center of the ruler body in the length direction; one end of the through hole is blocked by the use of the rear cover; the spring and the measuring rod seat are successively packaged in the through hole; the bottom end face of the measuring rod seat is contacted with the spring; the measuring rod is threadingly connected at the top of the measuring rod seat; the measuring rod extends out of the ruler body; an observation window which communicates with the through hole is arranged in the length direction of the ruler body; a scale is disposed at one side of the observation window on the ruler body; and the measuring rod seat is provided with a measuring rod seat scale which fits with the scale of the ruler body. The utility model has advantages as follows: as vernier principle is adopted to measure the groove depth of a small-bore groove part, the precision can reach 0.05mm; the exchangeable measuring-rod type small-bore groove depth measuring tool has strong versatility and has a simple structure; and the measuring rod has small diameter and has good interchangeability.

Description

A kind of interchangeable measuring staff formula osculum gash depth measurement measurer
Technical field
The utility model is related to a kind of interchangeable measuring staff formula osculum gash depth measurement measurer, belongs to measurer field.
Background technology
Among actual production, part structure has osculum groove, due to the characteristic of detection position during detection, and general general measurer can not be measured.
The content of the invention
The purpose of this utility model is to provide a kind of highly versatile, interchangeable measuring staff formula osculum gash depth measurement measurer simple in construction.
The purpose of this utility model is realized with the following methods:
The utility model includes:Blade, measuring staff, spring, bonnet, measuring rod seat, it is characterized in that:Blade center is provided with through hole along its length, one end of through hole is blocked with bonnet, spring, measuring rod seat are encapsulated in insertion dress hole successively, the bottom end face of measuring rod seat is contacted with spring, measuring staff is threaded in the top of measuring rod seat, and measuring staff stretches out the observation window being provided with along its length on blade, blade with through hole UNICOM, the side of observation window is provided with scale on blade, provided with the measuring rod seat scale matched with blade scale on measuring rod seat.
The utility model has the advantages that:The utility model measures the gash depth of osculum groove part using cursor principle, and precision can reach 0.05mm, highly versatile, simple in construction, and measuring staff diameter is small, interchangeability is good.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model;
Fig. 2 is Fig. 1 right view;
Fig. 3 is the structural representation of measuring rod seat.
Embodiment
Referring to the drawings, the utility model includes:Blade 2, measuring staff 1, spring 3, bonnet 4, measuring rod seat 5, blade center is provided with through hole 6 along its length, one end of through hole is blocked with bonnet, spring, measuring rod seat are encapsulated in insertion dress hole successively, the bottom end face of measuring rod seat is contacted with spring, measuring staff is threaded in the top of measuring rod seat, measuring staff stretches out blade, the observation window 9 with through hole UNICOM is provided with blade along its length, the side of observation window is provided with scale blade 7 on blade, provided with the measuring rod seat scale 8 matched with blade scale on measuring rod seat.The measuring staff that the utility model stretches out is interchangeable, and the different measuring staff of length, diameter can be changed according to different demands.During measurement, measuring staff top is goed deep into groove, channel bottom is withstood, blade is continued to push, until end face touches the top planes of tested groove at the top of blade, now read measuring rod seat and the scale on blade, scale uses cursor principle, and precision can reach 0.05mm.
