A combined coaxial processing and assembly structure of left and right buoys

Abstract

The invention provides a combined coaxial processing and assembling structure for left and right buoys. The combined coaxial processing and assembling structure comprises a left buoy and a right buoy; the left buoy is internally provided with a connecting expanding mould, the front section of the connecting expanding mould is in a fixed disc shaped structure, the rear section of the connecting expanding mould is in a lateral telescopic elastic structure, a through hole is formed in the connecting expanding mould, a connecting expanding pin penetrates through the through hole in the connecting expanding mould, the rear end of the connecting expanding pin takes the shape of a cone, the front end of the connecting expanding pin is in threaded connection with a nut, the outer diameter of the nut is larger than the diameter of the through hole of the connecting expanding mould, a screw hole is formed in the bottom of the rear end of the right buoy, the front end of a connecting screw is in threaded connection with the screw hole in the right buoy, and the rear end of the connecting screw is placed in a hole of the disc shaped structure on the front section of the connecting expanding mould. According to the combined coaxial processing and assembling structure, the left buoy and the right buoy are connected without glue, the influences of the thickness of a glue layer on the combination state of the left buoy and the right buoy are avoided, so that the problem of out of tolerance of the excircle coaxiality in the combined processing of the left buoy and the right buoy is fundamentally solved, and the percent of pass is increased to 99% from 60%.

Description

technical field [0001] The invention relates to a combined coaxial processing and assembling structure of left and right buoys. Background technique [0002] The left buoy and the right buoy are important parts of the liquid floating gyroscope, such as figure 1 As shown, the two parts are aluminum alloy thin-walled parts. The design requires that the two parts be combined to process the outer circle of φ26h7mm. At the same time, it is required that the coaxiality of the outer circle and the reference holes at both ends should not exceed φ0.01mm. Previously, it was used on the left float Apply 502 glue to the joint with the right buoy. After the two parts are combined and tightened, use the top clamp to lift the outer circle. The coaxiality of the processed outer circle is completely qualified when the glue is not removed, but the glue is removed. After that, enter the assembly workshop for secondary assembly inspection, and the coaxiality between the outer circle and the re...

[0002] The left buoy and the right buoy are important parts of the liquid floating gyroscope, such as figure 1 As shown, the two parts are aluminum alloy thin-walled parts. The design requires that the two parts be combined to process the outer circle of φ26h7mm. At the same time, it is required that the coaxiality of the outer circle and the reference holes at both ends should not exceed φ0.01mm. Previously, it was used on the left float Apply 502 glue to the joint with the right buoy. After the two parts are combined and tightened, use the top clamp to lift the outer circle. The coaxiality of the processed outer circle is completely qualified when the glue is not removed, but the glue is removed. After entering the assembly workshop for secondary assembly inspection, the coaxiality of the outer circle and the reference holes at both ends is out of tolerance by 40%, which will bring a bottleneck to the assembly process
