Abstract
The utility model discloses a deep hole internal step length measuring device. The deep hole internal step length measuring device comprises a dial gauge (1), a gauge seat (2) and a screw (3), wherein the dial gauge (1) is fixedly arranged at the upper end of the gauge seat (2) through the screw (3. The deep hole internal step length measuring device is characterized in that a small hole seat (4) is arranged at the lower end of the gauge seat (2), an extension bar (5) is arranged in the gauge seat (2), the upper end of the extension bar (5) is contacted with a gauge head of the dial gauge (1), the lower end of the extension bar (5) is provided with a measuring head (6), and a spherical crown part of the measuring head (6) is inserted into a center hole (8) in the upper surface of a big hole seat (7). Compared with the traditional measuring method using a vernier caliper, the deep hole internal step length measuring device disclosed by the utility model has the advantages that the measuring is convenient and accurate, the time and the labor are saved, the working efficiency is high, and the requirement on the product quality is ensured.
Description
Technical field
The utility model relates to a kind of measuring appliance, and length of bench measuring appliance in specifically a kind of deep hole is applicable to the less workpiece of measuring between the big aperture of step on every side.
Background technology
At present, vernier caliper is generally used in the measurement in the deep hole after the step turning processing; With the method for vernier caliper measurement, though existing widespread usage also has weak point; When particularly measuring the less workpiece of circumferential step between the big aperture, the one, with vernier caliper depth measurement degree, reference field is little; Measure inaccurately, error is big, influences product quality; The 2nd, measure trouble, waste time and energy inefficiency.
Summary of the invention
The purpose of the utility model is to provide a kind of convenient measurement accurate, time saving and energy saving, and high efficiency guarantees the interior length of bench measuring appliance of deep hole that product quality requires.
For reaching above purpose; The technical scheme that the utility model is taked is: length of bench measuring appliance in this deep hole, constitute by dial gauge, gauge stand, screw, and dial gauge is screwed the upper end at gauge stand; The aperture seat is established in the lower end that it is characterized in that gauge stand; Extension rod is located in the gauge stand, and the upper end contacts the lower end with the gauge outfit of dial gauge and establishes gauge head, and the spherical crown of gauge head partly inserts in the top center pit of macropore seat.The utility model is also implemented through following measure: the overall diameter of described aperture seat and macropore seat is complementary with the interior diameter of the processing workpiece of surveying.When using the utility model, according to measured workpiece step length dimension, with slip gauge dial gauge to zero, then with gauge stand with after the aperture seat is connected, be enclosed within workpiece on the macropore seat, indicated numerical value is exactly the size of the workpiece length of bench of surveying on the dial gauge at this moment.
The beneficial effect of the utility model is: compare with present method with vernier caliper measurement, it is accurate to have convenient measurement, time saving and energy saving, high efficiency, guarantee that product quality requires advantage.
