Abstract

The utility model discloses a narrow groove measuring micrometer which comprises a fixed measuring head (1), a micrometer rod (2), a micrometric screw (3), a fixed sleeve (4), a microdrum (5), a locking screw rod (6), and a force measuring device (7), wherein one end of the micrometer rod (2) is provided with the fixed measuring head (1), the other end of the micrometer rod (2) is provided with the fixed sleeve (4) and the micrometric screw (3), and the fixed sleeve (4) is provided with the microdrum (5), the locking screw rod (6), and the force measuring device (7). The utility model has simple structure and convenient measurement, and can directly measure the bottom diameter of a narrow groove.

Description

Narrow groove is measured milscale
Affiliated technical field
The utility model relates to milscale, is specifically related to a kind of narrow groove and measures milscale.
Background technology
The surface that conventional milscale can only detect workpiece is the broad bottom land very, narrow groove for workpiece can't detect, and only uses external callipers in conjunction with measurement, after elder generation has surveyed the diameter of bottom land with external callipers, measure clamp two with slide calliper rule again and survey size between pin, or with the degree of depth that fetches between dial gauge at the bottom of the measuring flume.Adopt above-mentioned two kinds of methods, exist defective and be: the one, efficiency of measurement and accuracy are lower, and the tightness of clamp is grasped inaccurate; The 2nd, dial gauge is indirectly measured and is had accumulated error, the accurate minimum point at the bottom of the alignment slot of gauge outfit simultaneously, and it is serious to form the phenomenon that groove gives up.
Summary of the invention
The purpose of this utility model is: provide a kind of narrow groove to measure milscale, the narrow groove of workpiece is detected accurately, guaranteed product quality effectively.
Technical solution of the present utility model is: this narrow groove is measured milscale, on the basis of original milscale, makes two terminal circle cylindricality gauge head into conical gauge head, and the top circular arc R can directly be measured the diameter of narrow bottom land less than 1 millimeter.This narrow groove is measured milscale and is comprised fixedly gauge head, chi bar, micrometric screw, fixed muffle, microdrum, locking screw handle, device for measuring force, end at the chi bar installs and fixes gauge head, the other end at the chi bar installs and fixes sleeve and micrometric screw, and microdrum and locking screw handle and device for measuring force are installed on fixed muffle.
Narrow groove of the present utility model is measured milscale, on original basis at original milscale, makes two terminal circle cylindricality gauge head into conical gauge head, and the top circular arc R is less than 1 millimeter.
Narrow groove of the present utility model is measured milscale, installs and fixes gauge head at an end of chi bar.
Narrow groove of the present utility model is measured milscale, installs and fixes sleeve and micrometric screw at the other end of chi bar.
Narrow groove of the present utility model is measured milscale, and microdrum and locking screw handle and device for measuring force are installed on fixed muffle.
The utility model is simple in structure, and it is convenient to measure, and can directly measure the footpath, the end of narrow groove.
Description of drawings
Fig. 1 is the utility model structural representation.
Among the figure: 1. fixedly gauge head, 2. chi bar, 3. micrometric screw, 4. fixed muffle, 5. microdrum, 6. locking screw handle, 7. device for measuring force.
Embodiment
As shown in FIG., this narrow groove is measured milscale and is comprised fixedly gauge head 1, chi bar 2, micrometric screw 3, fixed muffle 4, microdrum 5, locking screw handle 6, device for measuring force 7, end at chi bar 2 installs and fixes gauge head 1, the other end at chi bar 2 installs and fixes sleeve 4 and micrometric screw 3, and microdrum 5 and locking screw handle 6 and device for measuring force 7 are installed on fixed muffle 4.
Narrow groove of the present utility model is measured in the milscale, on original basis at original milscale, makes two terminal circle cylindricality gauge head into conical gauge head, and the top circular arc R is less than 1 millimeter.
Narrow groove of the present utility model is measured in the milscale, installs and fixes gauge head 1 at an end of chi bar 2.
Narrow groove of the present utility model is measured in the milscale, installs and fixes sleeve 4 and micrometric screw 3 at the other end of chi bar 2.
Narrow groove of the present utility model is measured in the milscale, and microdrum 5 and locking screw handle 6 and device for measuring force 7 are installed on fixed muffle 4.
During work,, screw the footpath, the end of the narrow groove that device for measuring force promptly surveys with the maximum in footpath at the bottom of fixedly gauge head 1 and micrometric screw 3 standing grooves.
