Embodiment Construction

[0029] Combine below figure 1 and figure 2 , the present invention is further described:

[0030] The flexible bearing inner diameter measuring jig of the present invention is specially used in cooperation with the pneumatic measuring instrument.

[0031] The pneumatic working method uses compressed air as the medium, and uses the characteristics of the flow or pressure of the air in the pipeline to change with the geometric size and shape of the pipeline to convert the size or displacement into the change of flow or pressure to achieve measurement. Pneumatic measuring instruments are divided into flow type, pressure type, flow rate type and so on according to the working principle. Among them, the pressure type pneumatic measuring instrument is often used for active measurement because it is easy to send out signals; the flow type and flow rate type are suitable for static measurement and are mostly used for inter-process detection.

[0032] Such as figure 1 As shown, a ...

Abstract

The invention relates to a flexible bearing bore diameter measuring clamp and a working method thereof. The flexible bearing bore diameter measuring clamp comprises a locating pillar (1), a base (2) and an air pipe (3); the locating pillar (1) is provided with an annular boss (5); a flexible bearing is put on the annular boss (5) in a sleeving manner and is supported and located by the annular boss (5); the side wall of the annular boss (5) is provided with a plurality of air holes (4) which right face the inner wall of the flexible bearing without contact with the flexible bearing; air outputby a pneumatic measuring instrument comes out from the multiple air holes (4) via the air pipe (3) and works on the bore diameter of the flexible bearing. The clamp has the advantages that the magnification times of the pneumatic measuring instrument are greater, human error is small, the measurement precision is not influenced, and there is no mechanical friction during work so that there is nohysteresis error.

Description

technical field [0001] The invention relates to a measuring fixture and a working method thereof, in particular to a measuring fixture and a working method thereof for detecting the inner diameter size and ellipse of thin-walled bearings and flexible bearings. Background technique [0002] Pneumatic measuring instrument is a new type of length measuring instrument used in the machinery manufacturing industry. Its principle is comparative measurement. The measurement method is to convert the length signal into an airflow signal, one is to indicate the value through the buoy in the glass tube with scale, which is called a buoy type pneumatic measuring instrument; the other is to convert the gas signal into an electrical signal through a gas-to-electric converter The light column indication value composed of luminous tubes is called an electronic column pneumatic measuring instrument. The pneumatic measuring instrument is used in conjunction with various pneumatic measuring h...
