The utility model discloses a having overcome the not enough of on the unable gaging spindle class part of ordinary measuring tool narrow deep trouth, having had simple structure, low cost, processing preparation are convenient, operation simple accurate, and advantages such as check -out time weak point, degree of accuracy height have very strong practicality.
Description
Technical field
This utility model relates to a kind of machine components instruments of inspection, particularly relates to a kind of axial workpiece narrow deep trouth groove
Deep measuring instrument.
Background technology
In the shaft element course of processing, the most domestic machining class is competed, it is often necessary to process narrow deeply
Groove (such as escape, jump-ring slot etc.)；On such axle, groove is the narrowest deep again, is greatly increased dimensional measurement difficulty.Often
Rule groover rot diameter survey tool (micrometer, slide gauge) cannot accurately measure narrow deep trouth size.
Summary of the invention
The purpose of this utility model is to provide a kind of axial workpiece narrow deep trouth groove depth measuring apparatus, it is possible to fully meet
Narrow deep trouth measurement requirement, provides a kind of special effective survey tool for processing narrow deep trouth.
In order to achieve the above object, this utility model be the technical scheme is that a kind of axial workpiece is narrow deeply
Groove deep measuring instrument, including: measure pin, V-type locating piece, amesdial and trip bolt；Wherein, described
Amesdial is connected with measuring pin；V-type locating piece top has boss, has through hole at boss geometric center；
Measure pin through the through hole on V-type locating piece；V-type locating piece side has screwed hole, and trip bolt passes
Amesdial is fixedly mounted on V-type locating piece by screwed hole；Measure axis and the V-type locating piece upper surface of pin
Vertically, and with the plane of symmetry of V-type locating piece overlap.
Further, square groove is opened bottom described V-type locating piece；Described measurement pin exceeds V-type locating piece
Bottom.
Further, angle formed by two inclined-planes of described V-type locating piece is 120 degree.
This utility model has the beneficial effect that this utility model patent overcomes ordinary measring tool and cannot measure
The deficiency of narrow deep trouth on axial workpiece, has simple in construction, with low cost, processing and fabricating convenience, operation letter
Easy row, the time is short in detection, accuracy advantages of higher, has the strongest practicality.

Detailed description of the invention
The utility model is described in further detail with embodiment below in conjunction with the accompanying drawings.
As it is shown in figure 1, a kind of axial workpiece narrow deep trouth groove depth measuring apparatus, including: measure pin 1, V-type location
Block 2, amesdial 3 and trip bolt 4；Wherein, described amesdial 3 is connected with measuring pin 1, amesdial 3
It is fixedly connected on V-type locating piece 2 by fastening bolt 4；Measure axis and the V-type locating piece 2 of pin 1
Upper surface is vertical；Described measurement pin 1 is through the through hole 2-3 of V-type locating piece, and exceeds V-type locating piece 2
Bottom, measure pin 1 axis overlap with the plane of symmetry of V-type locating piece 2.
As in figure 2 it is shown, the V-block that V-type locating piece 2 is made by one piece of 45 steel, its two V-type positions
Angle formed by the inclined-plane 2-1 of block is 120 degree, line cutting or milling machine milling can be used to form by blank material.
V-type locating piece 2 top design boss, is used for installing amesdial 3, and boss geometric center has an a diameter of 6mm
Through hole, for measure pin 1 pass；Open square groove bottom V-type locating piece 2, be used for accommodating measurement pin 1；
V-type locating piece 2 side has a screwed hole, trip bolt 4 to be fixedly mounted by amesdial 3 through this screwed hole
On V-type locating piece 2.
Embodiment:
Before using, measure the big footpath of part outer 5 with general measure instrument (micrometer, slide gauge),
Adjust amesdial 3, carry out school zero；
In using, first the V-type face of V-type locating piece 2 is adjacent to cylindrical 5, and makes measurement pin 1 be adjacent to part
The big footpath of cylindrical 5, rotates and ajusts measuring instrument, rotates amesdial 3, makes the scale 0 on dial plate align with pointer,
Take reading A1, then measurement pin 1 is shifted to narrow deep trouth, makes measurement pin 1 be adjacent to circle 6 at the bottom of narrow deep trouth, rotation
The flat measuring instrument of switch, take reading A again2；Finally give the narrow deep trouth diameter=big footpath of cylindrical-(A2-A1)·2。
