A kind of measurer for measuring guide vane viewport position degree
The utility model belongs to measures equipment technical field, is specifically related to a kind of measurer for measuring guide vane viewport position degree.
The viewport of guide vane is positioned on the installing plate on blade, for installing professional measuring sensor, is the viewport of the device of monitoring aircraft engine internal temperature and pressure size.The positional precision of viewport is very high, and its position degree directly affects the collection of related data.Because the tolerance of measured hole is larger, and in design drawing, there is no maximum solid mark, the method of grouping mea-sure is carried out in aperture by many employings, adopted in the past and checked pin interblock interference, namely the inspection pin that employing one is corresponding with standard sight hole size and shape inserts viewport to be detected, judges that whether the position degree of viewport to be detected is qualified with its fitness.This detection method can not read the actual value of the position degree of viewport to be detected, and needs operator to have higher operating experience.
Utility model content:
For solving prior art Problems existing, the utility model proposes a kind ofly to measure accurately, easily operation and the measurer for measuring guide vane viewport position degree of the position degree of viewport to be detected can be read accurately.
For realizing above object, the utility model by the following technical solutions: a kind of measurer for measuring guide vane viewport position degree, comprises base, base is provided with measuring appliance, some groups of fixtures, some locating pieces and several register pins; Described measuring appliance comprises measurer pedestal and measures axle, measure axle to be arranged in measurer pedestal and can to rotate freely, measure axle outer upper and be provided with dial gauge, measure in axle and be provided with measurement lever, the middle part measuring lever is arranged on by pivot pin to be measured in axle, the inner measuring lever is provided with measures pin, and outer end contacts with the measuring head of dial gauge, measures between the front portion of lever and measurement axle and is provided with spring.
Between described measurement axle and measurer pedestal, be provided with lining, measure axle and be arranged in lining, lining matches with measurer pedestal.
Described measurement pin is consistent with the distance of the measuring head of dial gauge and pivot pin with the distance of pivot pin.
Described fixture comprises the first fixture, the second fixture and the 3rd fixture, and the first fixture and the second fixture are separately positioned on front end and the rear end of tested part, and the 3rd fixture is arranged on the side of tested part.
The beneficial effects of the utility model: measurement result is accurate, processing ease, and the actual value that can read each viewport position degree easily.
Accompanying drawing illustrates:

Fig. 2 is the vertical view of the Fig. 1 after removing tested part;
Fig. 3 is the rear view of the Fig. 1 after removing tested part;
Fig. 4 is the cut-open view of Fig. 1 measuring appliance;
Wherein: 1-base, 2-measurer pedestal, 3-measures axle, 4-dial gauge, 5-lining, and 6-measures lever, 7-measures pin, 8-spring, 9-pivot pin, 10-tested part, 11-first register pin, 12-first fixture, 13-second fixture, 14-the 3rd fixture, 15-second register pin, 16-locating piece.
Below in conjunction with the drawings and specific embodiments, the utility model is described in further details, as shown in Figure 1 to 4, a kind of measurer for measuring guide vane viewport position degree, comprise base 1, base 1 is provided with measuring appliance, some groups of fixtures and the first register pin 11, second register pin 15, locating piece 16; Described measuring appliance comprises measurer pedestal 2 and measures axle 3, measures axle 3 and to be arranged in measurer pedestal 2 by lining 5 and can to rotate freely, lining and measure between axle 3 and keep gap 0.005 ~ 0.01mm.Measure axle 3 outer upper and be provided with dial gauge 4, measure axle 3 inside and be provided with measurement lever 6, the middle part measuring lever 6 is arranged on by pivot pin 9 to be measured in axle 3, the inner measuring lever 6 is provided with measures pin 7, the outer end measuring lever 6 contacts with the measuring head of dial gauge 5, measures between the front portion of lever 6 and measurement axle 3 and is provided with spring 8.
Described base is provided with the first fixture 12, second fixture 13 and the 3rd fixture 14, first fixture 12 and the second fixture 13 are separately positioned on front end and the rear end of tested part 10, 3rd fixture 14 is arranged on the side of tested part 10, base plate is respectively arranged with three the first register pins 11, two the second register pins 15 and a locating piece 16, when tested part 10 establish be placed on base 1 time, positioned by the end face of three the first register pins, 11 pairs of tested parts 10, the axis of two the second register pins, 15 pairs of tested parts 10 positions, positioned by the angle of locating piece 16 pairs of tested parts 10, and first fixture 12, second fixture 13, 3rd fixture 14 pairs tested part 10 clamps.The measurement pin 7 of measuring appliance contacts the inwall of the viewport of tested part 10.
Manually wheel measuring axle 3 measures the position degree of viewport, and in the rotation process measuring axle 3, the change of viewport position degree can be conducted to dial gauge by measuring pin 7 and measuring lever 6.Measure two torque arm length of lever 6 than being 1:1, thus dial gauge 4 dial reading reacting condition be the real position degree deviation of viewport.
