Abstract

The utility model discloses a measuring tool used for measuring depth of a blade seal groove. The measuring tool comprises a vernier universal bevel protractor and a measuring dial indicator. The vernier universal bevel protractor is used for measuring an angle between the blade seal groove and a plane. A spring is disposed below the measuring head of the measuring dial indicator. A measuring pin is connected with the lower part of the spring. The bottom part of the measuring pin is abutted against a horizontal surface of a depth plate. When a sheet disposed below the depth plate is inserted into the blade seal groove, the measuring pin moves toward the depth direction of the blade seal groove by using the elastic force of the spring, so that measuring data is achieved on the measuring dial indicator, and then the depth of the blade seal groove is measured. The measuring tool is simple in structure and rapid and accurate in measurement, and is suitable for depth measurement of various small-size components.

A kind of for measuring the blade measurer of groove depth of obturaging

Technical field

The utility model relates to a kind of measurer, particularly a kind of for measuring the blade measurer of groove depth of obturaging.

Background technology

The basin of the guide vane installing plate in aeromotor gas turbine to side and dorsad side have four grooves of obturaging, its groove width narrow dimension of obturaging is narrower, generally only has 0.8mm left and right, groove depth size is generally 2-4mm, the groove of obturaging of a blade is to be mutually connected with the groove of obturaging of next blade, the blade groove of obturaging is mainly used for placing the sheet of obturaging, but narrower due to the groove of obturaging, during measurement, measurer used is difficult to be deep into the groove inside of obturaging, and measure and obturage groove not in same direction, so measure the groove of obturaging, need multiple degree of depth measurer, measurer is complicated and changeable, be not easy to grasp and use.

Because the guide vane groove depth direction of obturaging becomes space angle with its outside surface, make the guide vane groove depth of obturaging measure and mostly all have several angles and a degree of depth difference, needed special depth gauge of each size design, each do not possess interchangeability and repeatability in the past.

Utility model content

The problem existing for prior art, the utility model disclose a kind of for measuring the blade measurer of groove depth of obturaging, can angle, the degree of depth is adjustable, can to the degree of depth, measure along with the space angle change of the groove of obturaging simultaneously.

To achieve these goals, the utility model adopts following technical scheme, a kind of for measuring the blade measurer of groove depth of obturaging, comprise vernier universal bevel protractor 8, described vernier universal bevel protractor 8 is by main scale 81, vernier 82, fixture block 83, brake head 84 forms, it is characterized in that: the degree of depth plate 1 that penetrates a L-type in the middle of fixture block 83, described degree of depth plate 1 transverse plane below arranges a thin slice, measuring pin 2 bottoms withstands on the transverse plane of degree of depth plate 1, the upright plane of degree of depth plate 1 passes from the top board of cover plate 7, described measurement is sold 2 tops and is connected with spring 9 bottoms, the top of spring 9 is connected with the measuring head 10 of measuring dial gauge 15, measuring the outer cover fitted lining cover 3 of pin 2 and spring 9, measure pin 2 is free to slide in lining 3, the bottom diameter of axle of lining 3 is connected with the bracket holes interference fit of support 4, at lining 3, the outer cover of measuring head 10 is equipped with table folder 12, described table presss from both sides 12 top cover loading nuts 11, measuring dial gauge 15 is placed in table folder 12, the top of support 4 and cover plate 7 are fixedly linked, and vernier 82, between support 4 and cover plate 7, and is connected with cover plate 7 with support 4 by screw 5, screw 6.

Preferably, the top of support 4 is fixedly connected with cover plate 7 by screw 14, pin 13.

The beneficial effects of the utility model:

Of the present utility model a kind of for measuring the blade measurer of groove depth of obturaging, not only solved in prior art because the inconvenient problem of the narrow measurement of notch that blade is obturaged groove, also solve problem how to measure notch and plane angulation simultaneously, can measure the degree of depth that multiple blade is obturaged groove with a kind of measuring tool simultaneously, simple in structure, measure quick and precisely, improved measuring accuracy.
