Description
Technical field
This utility model is related to in-process measurement field, the more particularly, to survey of the blade processing groove of CFM Engine Series 52
Amount device.
Background technology
The end face of the blade of CFM Engine Series 52 is provided with small groove, and flight crew is typically by judging the groove
Depth judging the wear extent of blade, the method for traditional measurement groove depth is, using slide calliper rule direct measurement, to be likely to result in groove depth
Measurement is inaccurate, so as to affect judgement of the flight crew to the wear extent of blade.
Utility model content
The purpose of this utility model is that and provide to solve the above problems and add for the blade of CFM Engine Series 52
The measurement apparatus of work groove..
This utility model is achieved through the following technical solutions above-mentioned purpose：
A kind of measurement apparatus for the blade processing groove of CFM Engine Series 52, including dial gauge, locating piece and probe,
The dial gauge includes table body, sleeve and measurement bar, and the probe is fixedly connected with the tip of the measurement bar, the locating piece
Through hole is inside provided with, the upper end of the through hole is connected with the lower end of the sleeve, the tip of the measurement bar is arranged on described leading to
In hole, and the probe is projected to outside the locating piece.
Specifically, with the locating piece near the table body end face as inner face, with described in the locating piece principle
The end face of table body is outer face, and the outer face is vertically arranged with the measurement bar, the sophisticated and outer end of the probe
Depth capacity of the distance between the face not less than the processing groove of 52 blade.
Preferably, the locating piece is T-shaped piece, and the area of the outer face of the locating piece is more than the end face of 52 blade
Area, the lateral surface of the lower end of the sleeve is provided with external screw thread, and the upper end of the through hole is provided with suitable with the external screw thread
The female thread matched somebody with somebody.
Specifically, the diameter with diameter greater than the measurement bar of the through hole.
The beneficial effects of the utility model are：
This utility model is used for the measurement apparatus of the blade processing groove of CFM Engine Series 52 and passes through locating piece, probe and hundred
Divide the cooperation of table, flexible by probe carries out accurate measurement, and not injuring part, easy to operate, manufacturing cost to groove depth
It is low.
Description of the drawings
Fig. 1 is the structural representation of the measurement apparatus for the blade processing groove of CFM Engine Series 52 described in the utility model
Figure.
Specific embodiment
Below in conjunction with the accompanying drawings the utility model is described in further detail：
As shown in figure 1, a kind of measurement apparatus for the blade processing groove of CFM Engine Series 52 of this utility model, including
Dial gauge, locating piece 4 and probe 5, dial gauge includes table body 1, sleeve 2 and measurement bar 3, and probe 5 is fixed with the tip of measurement bar 3
Connection, is provided with through hole 6 in locating piece 4, and the upper end of through hole 6 is connected with the lower end of sleeve 2, and the tip of measurement bar 3 is arranged on logical
In hole 6, and probe 5 is projected to outside locating piece 4, with locating piece 4 near table body 1 end face as inner face, with the principle of locating piece 4
The end face of table body 1 is outer face, and outer face is vertically arranged with measurement bar 3, and the distance between tip and outer face of probe 5 are no
Less than the depth capacity of the processing groove of 52 blades, locating piece 4 is T-shaped piece, and the area of the outer face of locating piece 4 is more than 52 blades
The area of end face, the lateral surface of the lower end of sleeve 2 is provided with external screw thread, in the upper end of through hole 6 is provided with and be adapted to external screw thread
Screw thread, the diameter with diameter greater than measurement bar 3 of through hole 6.
The operation principle that this utility model is used for the measurement apparatus of the blade processing groove of CFM Engine Series 52 is as follows：
Using front, locating piece 4 is connected on the sleeve pipe of dial gauge, and makes probe 5 project to the outer end of locating piece 4
Face；When using, first the outer face of locating piece 4 is conformed to into a horizontal plane, and registration is read from dial gauge, as base
Quasi- registration,
When in use, probe 5 is goed deep into groove, and the outer face of locating piece 4 is conformed to into the outer face of 52 blades, then
It is secondary to read the registration of dial gauge, and it is subtracted each other with benchmark registration, that is, draw groove depth.
For the ease of measurement, can by benchmark registration when be zeroed, then directly groove depth can be read by reading.
The technical solution of the utility model is not limited to the restriction of above-mentioned specific embodiment, every according to skill of the present utility model
The technology deformation that art scheme is made, each falls within protection domain of the present utility model.
