Going out, but affected by thread pitch, angle-measurement accuracy is the highest, and reading is the most inconvenient, and repeatability is unstable, and this can be straight
Connect and have influence on the accuracy that pressurized strut voltage is demarcated.
Summary of the invention
The problem existed for prior art, the present invention provides a kind of Middle casing air bleed valve angle continuous measuring device, breaks through
Middle casing inner flow passage narrow space and the restriction of air bleed valve installation site, it is possible to steady and continuous carry out angular surveying, and
Angle-measurement accuracy is high, and accuracy that pressurized strut voltage demarcate has been effectively ensured.
To achieve these goals, the present invention adopts the following technical scheme that a kind of Middle casing air bleed valve angle measures dress continuously
Putting, including bearing, pole, driving crank, connecting rod, driven crank and Digit Display Angle Ruler, described pole one end is connected to bearing
On, the pole other end is connected with driving crank one end by hollow hinge pin, and the driving crank other end is hinged with connecting rod one end, even
The bar other end is hinged with driven crank one end, and the driven crank other end is hinged on pole；Described Digit Display Angle Ruler passes through dial framework
Being packed on driven crank, wherein connecting rod is the measurement ruler of Digit Display Angle Ruler；Described driving crank is provided with push rod.
Described push rod is vertically mounted on driving crank, and push rod head is corresponding with air bleed valve, and driving crank and push rod pass through spiral shell
Stricture of vagina is connected, and by the stroke of threaded adjusting push rod, is additionally provided with locking nut on push rod.
Described pole, driving crank, connecting rod and driven crank constitute parallel-crank mechanism, and pole becomes with the angle of driving crank
Change amount is equal to the variable angle amount of connecting rod with driven crank.
The endoporus of described hollow hinge pin is set to interior hexagonal structure, and the outer-hexagonal of the endoporus of hollow hinge pin and air bleed valve installs bolt
Match.
The casing of described bearing connects end and uses warp architecture, bearing by the casing of bending connect end walk around Middle casing outer wall and
Middle casing is installed limit and is connected.
Beneficial effects of the present invention:
The present invention compared with prior art, breaches Middle casing inner flow passage narrow space and the restriction of air bleed valve installation site,
Apply the diagonal angle properties equivalent of parallel-crank mechanism simultaneously, and directly read angular values by Digit Display Angle Ruler, it is achieved that
The angular surveying of steady and continuous, and angle-measurement accuracy is high, and accuracy that pressurized strut voltage demarcate has been effectively ensured.

Detailed description of the invention
The present invention is described in further detail with specific embodiment below in conjunction with the accompanying drawings.
As shown in Figure 1, 2, a kind of Middle casing air bleed valve angle continuous measuring device, including bearing 1, pole 2, actively
Crank 3, connecting rod 4, driven crank 5 and Digit Display Angle Ruler 6, described pole 2 one end is connected on bearing 1, pole 2 another
End is connected with driving crank 3 one end by hollow hinge pin 7, and driving crank 3 other end is hinged with connecting rod 4 one end, connecting rod 4
The other end is hinged with driven crank 5 one end, and driven crank 5 other end is hinged on pole 2；Described Digit Display Angle Ruler 6 leads to
Crossing dial framework 8 to be packed on driven crank 5, wherein connecting rod 4 is the measurement ruler of Digit Display Angle Ruler 6；At described driving crank 3
On be provided with push rod 9.
Described push rod 9 is vertically mounted on driving crank 3, and push rod 9 head is corresponding with air bleed valve 11, driving crank 3 with
Push rod 9 is connected by screw thread, and by the stroke of threaded adjusting push rod 9, is additionally provided with locking nut 10 on push rod 9.
Described pole 2, driving crank 3, connecting rod 4 and driven crank 5 constitute parallel-crank mechanism, pole 2 and driving crank
The variable angle amount of 3 is equal to the variable angle amount of connecting rod 4 with driven crank 5.
The endoporus of described hollow hinge pin 7 is set to the outer-hexagonal peace of interior hexagonal structure, the endoporus of hollow hinge pin 7 and air bleed valve 11
Dress bolt 12 matches.
The casing of described bearing 1 connects end and uses warp architecture, and bearing 1 connects end by the casing of bending and walks around Middle casing 13
Outer wall is installed limit with Middle casing 13 and is connected.
The first use process of the present invention is described below in conjunction with the accompanying drawings:
First the measurement apparatus of the present invention is sent into the air bleed valve angular surveying position of Middle casing 13, the machine bent by bearing 1
Casket connects end and walks around the outer wall of Middle casing 13 and be connected to Middle casing 13 and install on limit, then hollow hinge pin 7 is enclosed within venting
The outer-hexagonal of valve 11 is installed on bolt 12, then adjusts the initial angle of pole 2 and driving crank 3, when pole 2 and active
After the initial angle of crank 3 puts in place, precession push rod 9 adjusts its stroke forward, until push rod 9 head acts against air bleed valve
11 surfaces, now screw locking nut 10 by locked for push rod 9 position, are finally reset by Digit Display Angle Ruler 6, final effect figure
As shown in Figure 3.
Starting angular surveying, open air bleed valve 11, air bleed valve 11 drives driving crank 3 by push rod 9 in opening process
Rotation, now the angle changing value of air bleed valve 11 is equal to the variable angle amount between pole 2 and driving crank 3, by parallel four
Shape diagonal angle, limit properties equivalent understands, and the variable angle amount between pole 2 and driving crank 3 is equal to connecting rod 4 and driven crank 5
Variable angle amount, and the variable angle amount of connecting rod 4 and driven crank 5 can directly be read by Digit Display Angle Ruler 6, it is achieved thereby that
The purpose that air bleed valve angle is measured continuously, and the Stability and veracity of angular surveying is the highest.
Scheme in embodiment is also not used to limit the scope of patent protection of the present invention, all equivalence enforcement done without departing from the present invention
Or change, it is both contained in the scope of the claims of this case.
