Abstract
The utility model discloses a testing fixture for detecting the form and location tolerance of an axial-flow compressor stationary guide blade crank. The testing fixture comprises a connection mainboard, a flat hole plug gauge and a round hole plug gauge, wherein the connection mainboard is provided with a flat hole and a round hole; one end of the round hole plug gauge is provided with a form and location tolerance detection end; the flat hole plug gauge is assembled in the flat hole; and a form and location tolerance detection end of the round hole plug gauge is assembled in the round hole. The testing fixture for detecting the form and location tolerance of an axial-flow compressor stationary guide blade crank can effectively detect the form and location tolerance of a crank for various turbine machines, and also can determine the position with problems during the detection process, and the detection results are accurate and reliable.
Description
Technical field
The utility model relates to mechanical dimension's testing tool, is specifically related to a kind of cubing for detection of axial compressor stator blade crank form and position tolerance.
Background technology
Axial compressor stator blade crank is the mechanical appliance of adjusting and control the Compressor Blades angle.The structure of axial compressor stator blade crank is with reference to figure 1, which is provided with flat hole and circular hole, the line L of center, flat hole and center of circular hole and flat hole longitudinal axis L ' between angle α be defined as the crank form and position tolerance, the value of α is generally 0 °～7 °, when if α can not satisfy drawing requirement, can cause axial compressor usability (pressure and flow) not reach designing requirement.
Need adopt numerical control three-dimensional coordinates measurement equipment to detect to the crank the detecting of the shape and position tolerance in the prior art.Detect that used numerical control three-dimensional coordinates measurement equipment price is expensive, cost is high, volume is large, is not suitable for Site Detection, has greatly increased production cost.
Summary of the invention
For defective or the deficiency of prior art, the purpose of this utility model is to provide a kind of suitable on-the-spot use and measurement cubing easy to use.
For realizing above-mentioned technical assignment, the utility model is taked following technical solution:
A kind of cubing for detection of axial compressor stator blade crank form and position tolerance, it is characterized in that, comprise and connect mainboard, flat stopple rule and plug gauge for testing circular-holes, described connection mainboard is provided with flat hole and circular hole, one end of described plug gauge for testing circular-holes is provided with form and position tolerance check end, and described flat stopple rule are assemblied in the flat hole.
But the form and position tolerance of the crank of the various turbomachineries of cubing efficient detection of the present utility model also can be determined the position that goes wrong in testing process, its testing result accurately and reliably.
Description of drawings
Fig. 1 is for connecting the structural representation of mainboard;
Fig. 2 is cubing of the present utility model structural representation in use.
Below in conjunction with embodiment and accompanying drawing the utility model is described in further detail.
Embodiment
With reference to figure 1 and Fig. 2, cubing of the present utility model comprises connection mainboard 1, flat stopple rule 3 and plug gauge for testing circular-holes 2, described connection mainboard 1 is provided with flat hole 6 and circular hole 7, one end of described plug gauge for testing circular-holes 2 is provided with form and position tolerance check end 4, described flat stopple rule 3 are assemblied in the flat hole 6, the form and position tolerance of described plug gauge for testing circular-holes 2 check end 4 tolerances for detection of degree in crank angle α.
The outer contoured shape that connects mainboard 1, and on flat hole 6 and size and the position relationship of the two of circular hole 7 consistent with the design processing request of crank to be measured.
The major diameter of flat stopple rule and size and the crank to be measured of minor axis are measure-alike accordingly.
The diameter dimension of circular hole is identical on the diameter dimension of plug gauge for testing circular-holes form and position tolerance check end 4 and the crank to be measured.
To connect mainboard 1 during detection and stack with crank 5, and the flat hole 6 that connects on the mainboard 1 is relative with the flat hole on the crank 5, the circular hole 7 that connects simultaneously on the mainboard 1 is relative with circular hole on the crank 5;
Then try the form and position tolerance of circular feeler gauge 2 check end 4 is filled in the circular hole that connects mainboard 1 and crank 5, can pass simultaneously smoothly the circular hole that connects on the mainboard 1 and the circular hole on the crank 5 such as form and position tolerance check end 4, illustrate that then the form and position tolerance of crank 5 is qualified; As the circular hole of form and position tolerance check end 4 on passing crank 5 the time be obstructed and wear to pass by, illustrate that then the form and position tolerance of crank 5 is defective.
