Abstract

The invention relates to a drilling die and clamp for an electro-hydraulic servo valve magnetizer, comprising a jig body (1), a drill sleeve (2), a horizontal positioning mechanism, and a compaction mechanism. The invention is characterized in that: the drill sleeve (2) is tightly matched in a mounting hole of the jig body; the horizontal positioning mechanism comprises an L-shape positioning plate (4) and two U-shape slide positioning plates (3); wherein, the L-shape positioning plate is arranged on an installation position on the jig body and is fixed on the jig body through a Straight pin (51) and a screw (62); a through hole is arranged at the bottom of the U-shape slot of the slide positioning plate, and a magnetizer is positioned through one end of the U-shape slot. The invention has the advantages of convenient magnetizer positioning, convenient manufacturing of locating holes on the magnetizer, assurance of consistency of positioning precision for repetitious installation of jigs, improvement of work efficiency, and less requirements to the technological levels of workers while assuring demands of manufacturing.

Description

technical field [0001] The invention relates to a machining fixture for precision small parts, in particular to a drilling mold fixture for a magnetic conductor of an electro-hydraulic servo valve. Background technique [0002] The electro-hydraulic servo valve is an electro-hydraulic servo control component with high precision and high dynamic response used in the electro-hydraulic control system, which can be used in the hydraulic control system of precise displacement, speed, force and acceleration. The magnetizer is an important part of the electro-hydraulic servo valve, and its physical properties are very demanding. It is a key part of the torque motor of the electro-hydraulic servo valve. Its structure is shown in Figure 1. [0003] If the machining accuracy cannot be accurately positioned, the performance of the torque motor will be reduced and the service life will be reduced. In addition, the fixtures in the prior art are inconvenient to use, and the technical req...
