Abstract

The invention relates to a clamp for armature centre positioning in electrohydraulic servo valve, comprising a drill jig body (1), two positioning blocks (2), a cushion block (3) and a compaction mechanism; the drill jig body (1) is a concave structure with windows arranged on both sides to coordinate with the positioning blocks(2); the transfixion between the two windows is the installation position of the cushion block (3); the bottom of the drill jig body (1) is equipped with a screwed hole for fixing bracket; the positioning blocks (2) are installed in the window arranged on both sides ofthe drill jig body (1); the cushion block (3) is arranged in installation position of the cushion block (3) arranged between the two windows of the drill jig body (1), and two grooves that contain the armature(11) are arranged above the cushion block (3). The invention has the advantages of convenient and simple clamping, high accuracy in repetitive positioning and rotating, high efficiency and low cost. The processed valve housing has accurate hole position and good consistency; thus the processing efficiency is greatly improved, and the technical level requirement of the workers is reduced.

Description

technical field [0001] The invention relates to a machining fixture for precision small parts, in particular to a fixture for positioning the center of an armature 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 armature has higher requirements in the parts of electro-hydraulic servo valves. At present, there are the following problems in the machining of similar domestic products. defect: [0003] The positioning is mainly done by fitters, and its characteristics are: increased workload, low efficiency, increased processing costs, reduced output, low precision, poor consistency, and cannot mee...
