Abstract

The utility model discloses a steel wire size measurement device, the one end of steel wire is fixed in the left side of device, and the other end then lies in the slip end on device right side, and the end that slides can freely slide on the guide rail to apply the pretightning force through hanging spring -balance and weight to the steel wire. The upper portion installation micrometer sub -assembly of device can be followed the steel wire direction and slided to it is fixed to advance line location. It passes to follow the miking center of keeping silent during the steel wire installation. The upper and lower separation of keeping silent of micrometer is kept silent to the measuring junction on, keeps silent to rotatable end down, fixes respectively in same inner disc, and inner disc can wind the outer disc free rotation along the center. The level that sets up on inner disc and two perpendicular fixed pins to fix inner disc. This device can be fixed the steel wire, pretension and alignment, and its micrometer sub -assembly can carry out the precision measurement to gauge of wire and out -of -roundness.

Description

A kind of gage Size measurement apparatus

Technical field

This utility model is related to a kind of device, in particular, is related to a kind of gage Size measurement apparatus.

Background technology

At present, the common gage Size measuring instrument of laboratory is micrometer, and degree of accuracy is up to 0.01mm.Micrometer removes to be used Outer in steel wire measurement, it is also widely used for the measurement of other various products sizes.However, micrometer also has its limitation.For example, Due to the impact that steel wire is not fixing and itself bending brings, measurement diameter is often not accurate.In measuring steel wire out-of-roundness, from Level, vertical both direction are difficult to fix position, and translation-angle is forbidden, and leads to the measurement of out-of-roundness also inaccurate.Therefore, grind Make a kind of new gage Size measurement apparatus the size quality guaranteeing steel wire is necessary.

Utility model content

Can not fix during conventional miking steel wire diameter and straightening steel wire to overcome, and measurement out-of-roundness when pair The defect that steel wire positioning is forbidden with translation-angle, this utility model provides a kind of gage Size measurement apparatus simple to operation, Steel wire can be fixed, pretension straightening and being accurately positioned, and Accurate translation from level to vertical angle, thus accurately fast The prompt size detecting steel wire is it is ensured that wire quality is qualified.

This utility model solves its technical problem and be the technical scheme is that a kind of gage Size measurement apparatus.It is special Levy and be: one end of steel wire is fixed on the left side of device, the other end is then located at the sliding end on the right side of device, and sliding end can be in guide rail On slidably, and pretightning force is applied to steel wire by spring scale and counterweight, size is less than the 2% of steel wire nominal Fracture Force. The top of measurement apparatus is installed can be parallel with steel wire and permissible along the micrometer molectron of sliding bar, its glide direction It is fixed on the positioning, steel wire passes through from miking jaw center when installing.The upper and lower jaw of micrometer separates, and upper jaw is Measurement end, lower jaw is rotatable end, is separately fixed in same inner disk, and inner disk can along center around outer disc freely Rotate.Inner disk arranges steady pin at horizontal and vertical two, to be fixed to inner disk.

The beneficial effects of the utility model are, by fixation with steel wire and pretension straightening, and slidably with thousand rotating Divide chi molectron to be accurately positioned, can effectively eliminate the mistake brought when conventional miking steel wire diameter and out-of-roundness Difference, so that it is guaranteed that steel wire product quality.

Specific embodiment

The technical program is a kind of gage Size measurement apparatus: as Fig. 1,2, one end of steel wire 4 is fixed on the left side of device, The other end then be located at device on the right side of sliding end, sliding end can on guide rail 6 slidably, and by spring scale 3 and counterweight 7 right Steel wire 4 applies pretightning force, and size is less than the 2% of steel wire 4 nominal Fracture Force.The top of measurement apparatus is installed can be along slide bar 2 The micrometer molectron 1 slided, its glide direction is parallel with steel wire 4, and can be fixed on the positioning.Steel wire 4 install when from Miking jaw center passes through.The upper and lower jaw of micrometer separates, and upper jaw 9 is measurement end, and lower jaw 13 is rotatable End, is separately fixed in same inner disk 12, inner disk 12 can be freely rotatable around outer disc 10 along center.In inner disk 12 Steady pin 11 at upper setting horizontal and vertical two, to be fixed to inner disk 12, consequently facilitating carry out diameter and out-of-roundness Measurement.This apparatus structure is simple, is used conveniently and safely, testing staff easily operates, so that it is guaranteed that detection data is accurate.
