Abstract

The invention discloses a detection tool for an inner diameter of a thread. The detection tool comprises a left probe slide block body, a measuring extension rod, a measuring main body, an acting warping plate, a right push rod, a right probe slide block body, an upper push rod and a ranging dial indicator, wherein the left probe slide block body is fixedly connected with the measuring extension rod; the measuring extension rod is fixedly connected with the measuring main body; the acting warping plate, the right push rod, the right probe slide block body and the upper push rod are respectively mounted in the measuring main body; the right push rod is respectively in contact with the right probe slide block body and the acting warping plate; the ranging dial indicator is mounted at the top of the measuring main body; and the upper push rod is respectively in contact with the acting warping plate and the ranging dial indicator. The detection tool provided by the invention can be used for quickly and accurately finishing the measurement for the inner diameter of a large-size thread; the detection tool is simply used and operated; and an operator can easily detect the inner diameter of the thread in real time during a machining process.

Description

A kind of minor diameter of thread testing tool
Technical field
The present invention relates to a kind of minor diameter of thread testing tool.
Background technology
At present; Detection method for internal thread diameter in large-scale internal thread part production and processing industry is varied; But most method and testing tool all are according to production operation workman's protracted experience and several criteria measurer, in cover can be to the heavy parts process, can simply not detect and reach the testing tool of degree of precision fast through method simply and easily.
Summary of the invention
The object of the present invention is to provide a kind of minor diameter of thread testing tool, the present invention can accomplish the measurement to large-scale minor diameter of thread rapidly and accurately, and use simple to operate, the easy operating worker in process in real time the double thread internal diameter detect.
In order to achieve the above object, technical scheme of the present invention is:
A kind of minor diameter of thread testing tool comprises left probe slide body, measures extension rod, measures main body, acts on seesaw, right push rod, right probe slide body, upper push-rod, range finding dial gauge; Wherein said left probe slide body is connected with the measurement extension rod; Described measurement extension rod is connected with the measurement main body; Be separately installed with effect seesaw, right push rod, right probe slide body and upper push-rod in the described measurement main body, and right push rod contacts with right probe slide body and effect seesaw respectively; Described measurement main body top is equipped with the range finding dial gauge, and described upper push-rod contacts with effect seesaw and range finding dial gauge respectively.
Beneficial effect of the present invention is: the present invention has designed a cover and has used minor diameter of thread survey instrument simple and easy and that measuring accuracy is high, acts on the stroke that moves up and down that the effect seesaw drives upper push-rod and makes the range finding dial gauge show the respective accurate values thereby promote right push rod through right side probe slide body.The instrument that the operator is accurately detected the internal thread part of its processing fast; To eliminate the present situation that in large-scale screw thread processing industry, detects the numerous and diverse inefficiency of minor diameter of thread at present; This testing tool can be accomplished the measurement to large-scale internal thread part internal diameter apace; Can reach certain accuracy again, and have simple to operate, be easy to use and production and processing all comparatively convenient.
This mechanism.
Description of drawings
Fig. 1 is a structural representation of the present invention;
Fig. 2 is a fundamental diagram of the present invention.
Embodiment
A kind of minor diameter of thread testing tool, as shown in Figure 1; Comprise left probe slide body 1, measure extension rod 2, measure main body 3, effect seesaw 4, right push rod 5, right probe slide body 6, upper push-rod 7, range finding dial gauge 8; Offer 1 M6 threaded hole on the described measurement extension rod 2; Also offer 1 M6 threaded hole on the described measurement main body 3; Wherein said left probe slide body 1 passes through threaded hole with measurement extension rod 2, and utilizes bolt 10 to be connected; Described measurement extension rod 2 passes through threaded hole with measurement main body 3, and utilizes bolt 10 to be connected; Be provided with the space in the described measurement main body 3, be separately installed with effect seesaw 4, right push rod 5, right probe slide body 6 and upper push-rod 7, and right push rod 5 contacts with right probe slide body 6 and effect seesaw 4 respectively; Described measurement main body 3 tops are equipped with range finding dial gauge 8, and described upper push-rod 7 contacts with effect seesaw 4 and range finding dial gauge 8 respectively.Described left probe slide body 1 probe can be installed different model probe ball according to tested thread pitch.Described right probe slide body 6 probes can be installed different model probe ball according to tested thread pitch.
As shown in Figure 2; The minor diameter of thread testing tool is selected left probe slide body 1 and right probe slide body 6 probe ball diameter according to tested internal thread part 9 pitch; And according to the internal thread part roughly internal diameter regulate to measure extension rod 2 and the fastening bolt of measuring on the main body 3; And minor diameter of thread testing tool level inserted in the screw thread of the tested internal thread part 9 in same plane, according to measuring range finding dial gauge reading, read minimum value and be internal thread maximum inner diameter position dimension.
