[0023] A device for detecting arc diameter using a pneumatic measuring instrument comprises a pneumatic electronic column 1, a control panel 2 is arranged on the surface of the pneumatic electronic column 1, a numerical observation column 3 is arranged on the surface of the pneumatic electronic column 1, a gas supply joint 4 is fixedly installed on the surface of the pneumatic electronic column 1, a gas supply pipeline 5 is fixedly connected to the surface of the gas supply joint 4, a measuring bracket 7 is fixedly connected to the surface of the gas supply pipeline 5, a handle 6 is fixedly connected to the measuring bracket 7 at the bottom, a diameter measuring body 8 is fixedly installed at the bottom of the measuring bracket 7, a threaded groove 9 is provided on the surface of the diameter measuring body 8, a locking screw 10 is threadedly connected to the threaded groove 9, a gas supply groove 11 is provided on the surface of the diameter measuring body 8, and an air outlet 12 is provided on the surface of the diameter measuring body 8. The device for measuring the diameter of the arc is convenient for measuring the semicircular arc diameter of a part, and can be directly measured at a work station, thereby reducing the measurement of the three coordinates of the part and improving the measurement efficiency.

[0024] Furthermore, the pneumatic electronic column 1 transports gas to the inside of the gas pipeline 5 through the gas connector 4. A circular hole is opened on the surface of the handle 6. The gas pipeline 5 is fixedly connected to the circular hole of the handle 6. The gas pipeline 5 runs through the handle 6 as a whole. The handle 6 facilitates the operator to hold one end of the gas pipeline 5.

[0025] Furthermore, two groups of circular holes are opened on the surface of the measuring bracket 7, and the locking screw 10 passes through the circular holes of the measuring bracket 7 and is threadedly connected to the thread groove 9. The circular hole of the measuring bracket 7 is aligned with the thread groove 9 on the diameter measuring body 8, so that the locking screw 10 passes through the circular hole of the measuring bracket 7 and rotates on the thread groove 9. During the rotation of the locking screw 10 on the thread groove 9, the measuring bracket 7 and the diameter measuring body 8 are installed together.

[0026] Furthermore, two groups of thread grooves 9 and locking screws 10 are provided, and the locking screws 10 install the diameter measuring body 8 on the bottom of the measuring bracket 7 through the thread grooves 9. The position of the fixed connection between the measuring bracket 7 and the diameter measuring body 8 is determined. After the fixing of the measuring bracket 7 and the diameter measuring body 8 is completed, the gas pipeline 5 at the bottom of the measuring bracket 7 will be engaged on the gas groove 11.

[0027] Furthermore, a semicircular groove is provided at the bottom of the measuring bracket 7, and the diameter measuring body 8 is installed on the semicircular groove of the measuring bracket 7. The diameter measuring body 8 is cylindrical as a whole. When detecting the diameter of a part, the diameter measuring body 8 needs to be placed on the semicircular end face of the part.

[0028] Furthermore, one end of the gas pipeline 5 away from the gas connector 4 passes through the measuring bracket 7 and is snap-connected to the gas groove 11. The gas inside the gas pipeline 5 is transported to the gas groove 11 through the handle 6 and the measuring bracket 7, so that the pneumatic electronic column 1 transports the gas to the inside of the diameter measuring body 8 through the gas pipeline 5. The diameter measuring body 8 uses the gas as the detection medium to detect the arc end face diameter of the part.

[0029] Furthermore, the gas delivery groove 11 and the gas outlet 12 are interconnected, the gas delivery groove 11 and the gas outlet 12 are perpendicular to each other, and the gas delivery groove 11 is located at the center of the gas outlet 12. The gas delivery groove 11 delivers gas to both sides of the diameter measuring body 8 through the gas outlet 12, and the diameter measuring body 8 then delivers the gas to the arc end face of the part.

[0030] Working principle: The inspector places the diameter measuring body 8 on the arc end face of the part to be inspected through the handle 6, and the pneumatic electronic column 1 delivers gas to the inside of the gas pipeline 5 through the gas supply connector 4. The gas passes through the handle 6 and the measuring bracket 7 and enters the gas supply groove 11. The gas supply groove 11 delivers the gas to both sides of the diameter measuring body 8 through the air outlet 12. The gas on both sides of the diameter measuring body 8 will act on the arc of the part. Since the arc diameters of the parts are different, different changes in air pressure will be generated. By observing the pressure of the air outlet displayed by the numerical observation column 3, the arc diameter of the part can be measured.

[0031] Place the diameter measuring body 8 on the semicircular groove at the bottom of the measuring bracket 7, and then pass two sets of locking screws 10 through the circular holes of the measuring bracket 7 so that the locking screws 10 can rotate in the threaded groove 9 on the diameter measuring body 8. The diameter measuring body 8 can then be installed on the bottom of the measuring bracket 7, making it easy to replace and maintain the diameter measuring body 8.
