Embodiment
In order to facilitate the understanding of the purposes, features and advantages of the present invention, it is below in conjunction with the accompanying drawings and specific real
Applying mode, the present invention is further detailed explanation.
As shown in figure 1, in a specific embodiment, being detected provided by the present invention for flange shaft threaded hole position
Special gauge includes mounting bracket, and the mounting bracket includes the top plate 1 of horizontal bottom plate 7, vertical riser 2 and level, institute
The lower end for stating riser 2 is connected on the bottom plate 7, and the top plate 1 is connected to the upper end of the riser 2.
The top plate 1 is provided with the thimble 9 being connected with pressing tongs 8, the pressing tongs 8 through the top plate 1, the pressing tongs 8
The thimble 9 can be promoted to move up and down.
The middle part of the riser 2 is connected with horizontal supporting plate 4, the supporting plate 4 and is provided with positioning seat 3, convex
Mould 10 and lead 12.The positioning punch-pin 10 is embedded in the positioning seat 3, and the positioning punch-pin 10 can be in the positioning
Freely rotated in seat 3.The upper end of the positioning punch-pin 10 is formed with bulge-structure (not shown), and the shape of the bulge-structure is with treating
The shape of the petal-shaped inner chamber of the flange shaft 17 of detection matches.In the present embodiment, the lower surface of the positioning punch-pin 10 and institute
State and back-moving spring 11 is additionally provided between positioning seat 3, the positioning punch-pin 10 can fluctuate in the positioning seat 3.
The lead 12 is fixed to wear and is connected on the positioning punch-pin 10, and the lower end of the lead 12 extends downwardly out institute
Supporting plate 4 is stated, the lower end of the lead 12, which is connected with measurement plate 13, the measurement plate 13, is connected with the first meter connector 14.
When the positioning punch-pin 10 horizontally rotates, drive first meter connector 14 synchronous through the lead 12 and the measurement plate 13
Horizontally rotate.
In the present embodiment, the bottom of the riser 2 is also associated with vertically wearing on horizontal dial framework 5, the dial framework 5
Push rod 15 is connected to, the upper end of the push rod 15 and the lower end of the lead 12 are inconsistent, and the lower end of the push rod 15 is connected with
Second meter connector 6.When the lead 12, which is pressurized, to be moved down, it can drive the push rod 15 is synchronous to move down.
Please continue to refer to shown in Fig. 1, what the present embodiment was provided is used for the special gauge that flange shaft threaded hole position is detected
Application method and operation principle it is as follows:
(1) measuring head of the first dial gauge (not shown), is connected to first meter connector 14 first, by the second percentage
The measuring head of table (not shown) is connected to the second meter connector 6, then carries out normal place to the first dial gauge and the second dial gauge
Degree is compared with zero.
(2), then, three measuring sticks 16 are screwed in the screwed hole of flange shaft 17 to be detected, pull-up pressing tongs 8, through surveying
Flange shaft 17 to be detected is placed on the positioning seat 3 by length bar 16 so that the inner chamber of flange shaft 17 and the positioning punch-pin 10
Upper end it is at a fully engaged.Then, leave behind pressing tongs 8 so that thimble 9 withstands the upper surface of the axle portion of flange shaft 17 to be detected.
(3), then, rotate flange shaft 17 to be detected, drive the positioning synchronous axial system of punch-pin 10, turn of positioning punch-pin 10
Dynamic the first meter connector 14 driven to by guide rod 12 in measurement plate 13, measurement plate 13 stirs the measuring head of the first dial gauge,
So as to realize the position degree detection to the screwed hole of flange shaft 17 to be detected.In addition, flange shaft 17 to be detected is pushed up by thimble 9
While tight, positioning punch-pin 10, which is pressurized, to be moved down, and back-moving spring 11 shrinks, and guide rod 12 compresses downwards push rod 15, and push rod 15 drives
Second meter connector 6 moves down and stirs the measuring head of the second dial gauge, so as to realize segment length's detection to flange shaft 17 to be detected.
(4) after, test terminates, flange shaft 17 to be detected is removed, the decompression of back-moving spring 11 resets, and finally promotes convex
Mould 10, which floats, to be resetted.
It can be seen that, the present invention can be realized and the position degree of the screwed hole of flange shaft is entered by simple Design of Mechanical Structure
Row detection, it greatly lifts detection efficiency, reduces testing cost.
The description with certain particularity detailed enough has been carried out to the present invention above.Ordinary skill in art
Personnel are it should be understood that what the description in embodiment was merely exemplary, before without departing from true spirit and scope of the present invention
Put make it is all change should all belong to protection scope of the present invention.Scope of the present invention is by described power
What sharp claim was defined, rather than limited by the foregoing description in embodiment.
