Abstract

The invention discloses a cylindrical surface fixed-phase pin hole wire cutting tool for a planetary lead screw. The tool comprises a workpiece fixing frame, a transition dividing plate and a fixing support, wherein the workpiece fixing frame is of a three-stage step shaft structure, a fixed phase wire penetrating hole is machined in a middle cylindrical section, the position of the wire penetrating hole is consistent with the position of the workpiece fixed phase pin hole, the workpiece is arranged on the outer side of the middle cylindrical section of the step shaft structure in a sleeving mode and is locked through a limiting gasket and a workpiece fixing nut, the workpiece fixing frame is fixedly connected with the transition dividing plate, the transition dividing plate is fixed on the fixing support, and dividing phase positioning is carried out on a fixed pin. The invention further discloses a cylindrical surface fixed-phase pin hole wire cutting method for the planetary lead screw. According to the tool and the method, the required phase rotation (such as 90 degrees) is realized through the dividing pin holes of the transition dividing plate, the locking mode is convenient,the alignment time can be shortened, and the processing efficiency is greatly improved.

Description

technical field

[0001] The invention relates to a wire-cutting tool and a wire-cutting method for a cylindrical surface phase-fixed pin hole for a planetary screw, belonging to the category of mechanical manufacturing. Background technique

[0002] The planetary screw is one of the main transmission mechanisms in the aerospace electromechanical servo transmission mechanism. During the movement of the planetary screw, the axial parallelism of the roller needs to be controlled by the gears on both sides of the nut. The parallelism of the screw rod and the ring gear fixed on both sides of the nut need to be kept in the same phase. Due to the maturity of the dual gear processing technology, but limited by the narrow space in the inner cavity of the nut, although the inner ring gear of the nut ring gear consolidation structure can be realized by using the gear shaping machine, the requirements for the function of the gear shaping machine are high, and there are currently existing...
