Description

Technical Field

[0001] This utility model relates to the field of flexible wheel machining technology, and in particular to a flexible wheel machining fixing fixture. Background Technology

[0002] Harmonic reducers are widely used in precision positioning fields such as mechanisms and instruments in aerospace vehicle control systems. They are a transmission technology developed based on the elastic deformation of thin shells. The flexible wheel is a key component of the harmonic reducer. The flexible wheel is generally a thin-walled part, and it needs to be fixed by a fixture during the processing. Traditional flexible wheel fixing fixtures are difficult to use for flexible wheels of different specifications, and may cause deformation of the flexible wheel during fixing, affecting the processing. This paper proposes a flexible wheel processing fixing fixture. The rotating disk driven by the motor controls the movement of the clamping block, so that the clamping block fits against the inner wall of the flexible wheel. The large contact area can reduce the possibility of deformation during the fixing and clamping of the flexible wheel. Utility Model Content

A rotating disk is provided on one side of the fixing plate, and a fixing box is sleeved on the outside of the rotating disk. A fixing box cover is provided on one side of the fixing box, and a guide groove is opened inside the rotating disk. A moving rod is connected inside the guide groove, and a clamping block is connected to one end of the moving rod. A fixing flange is provided on one side of the fixing box, and a fixing connecting rod is connected to one side of the fixing flange. The other end of the fixing connecting rod is fixedly connected to the support column.

[0006] Preferably, the fixed box body has a turntable groove inside, and the shape and size of the turntable groove match the rotating disk.
