Abstract

The utility model relates to a spiral inner diameter micrometer which is invented for specially measuring the inner diameter of containers with various shapes. By utilizing the machining precision of threads, a measuring tool which is freely stretchable and can measure the inner diameter can be produced and can be used for measuring the inner dimension of the containers with various shapes more accurately.

Description

The spiral internal diameter micrometer
Technical field
The utility model spiral internal diameter micrometer relates to the precision measuringtoll in a kind of mechanical engineering field.
Background technology
In the field of Machine Design, processing and measurement, measure the measurer of length, ruler, tape measure, slide calliper rule, curved chi, internal diameter chi and spiral micrometer or the like are arranged.But when the internal diameter of the container that needs accurately to measure certain bulge shape, often will feel to be in a rush and muddle a little.(for example wanting to understand the accurate wall thickness of some container that is unearthed ancient times, when reaching which kind of level) with comment process technology in ancient times
Summary of the invention
The utility model spiral internal diameter micrometer, system is made into as existing, existing general spiral external diameter micrometer, the utensil that the accurate internal diameter tolerance of tangible exact scale and retractable is arranged: an end of core pipe (E) embeds a little steel ball (H), in fine thread on its external diameter, on the car, be carved with scale (F) on it; Outer tube (G) end also be carved with yardstick and the pipe in car the internal thread that cooperates with core pipe (E) is arranged, the other end of outer tube (G) also embeds a little steel ball (H).
Description of drawings
Fig. 1 is to use the synoptic diagram of this spiral internal diameter micrometer.(A) be certain part container; (B) be the inwall of this container; (C) be the schematic appearance of spiral internal diameter micrometer; (D) be slip gauge for guaranteeing when differing heights is measured, need fill up.
Fig. 2 is the structural map of spiral internal diameter micrometer.
(E) be the core pipe, its end embeds a little steel ball (H), to guarantee measuring accuracy; The other end is in fine thread on its external diameter, on the car, and (for example pitch is 1mm, or littler) is carved with scale (F) on it
G is an outer tube, its end also be carved with yardstick and the pipe in car the internal thread that cooperates with core pipe E is arranged, the other end also embeds a little steel ball (H).
Embodiment
During concrete operations, the slip gauge (D) of respective thickness is put in first position of certain height of surveying according to anticipation, can keep certain height in the container and is in horizontality to guarantee that the spiral internal diameter micrometer is put into.In order to prevent that the spiral internal diameter micrometer from placing out-of-levelly because of external diameter differs, it is identical with outer tube (G) to process an external diameter in advance, and the casing pipe sleeve that internal diameter equates with the external diameter of core pipe (E) again is in core pipe (E) outside.(this sleeve pipe is not drawn),
In order to adapt to the inside diameter of vessel of measuring different size, the spiral internal diameter micrometer can be made serial size as standby.

Claims (1)

1. the utility model spiral internal diameter micrometer relates to a spiral micrometer capable of expansion and contraction, as can to measure the different shape inside diameter of vessel; It comprises: an end of core pipe (E) embeds a little steel ball (H), in fine thread on its external diameter, on the car, is carved with scale (F) on it; One end of outer tube (G) also be carved with yardstick and the pipe in car the internal thread that cooperates with core pipe (E) is arranged, the other end of outer tube (G) also embeds a little steel ball (H).
