Abstract

The invention relates to a processing fixture for the through hole on the valve sleeve of an electro-hydraulic servo valve, which comprises a drill body (2) and a drill sleeve (6), and is characterized in that the drill body (2) is a hollow octahedron, There are placement holes for drill sleeves (6) on its eight faces, positioning pin placement holes (4) on one edge, positioning screw placement holes (1) on its symmetrical edges, and the drill sleeve (6) ) is arranged in the placement hole provided on the surface of the drill template body (2); the positioning pin and the positioning screw are arranged in the placement hole. The invention makes the processing and clamping of the through hole on the valve sleeve in the electro-hydraulic servo valve more convenient and simple, has high repeat positioning and rotation precision, high efficiency and low cost. The hole position of the processed valve sleeve is correct and the consistency is good, which greatly improves the processing efficiency and reduces the requirement for the technical level of workers.

Description

technical field [0001] The invention relates to a machining fixture for precision small parts of an electro-hydraulic servo valve, in particular to a machining fixture for a through hole on a valve sleeve in an electro-hydraulic servo valve. Background technique [0002] The development of electro-hydraulic servo valves in the international professional field has gone through more than 50 years, and the application occasions are becoming more and more extensive. However, the research on servo valves in China is still in a relatively backward state, especially the machining and manufacturing of important parts is more prominent. The mechanical processing of domestic similar products has the following defects: [0003] Mainly use the universal dividing head to index and position the processing of the through hole on the valve sleeve. Its characteristics: the increased workload will inevitably lead to low efficiency, increased processing costs, and reduced output, which cannot...
