Background technology
Electrohydraulic servo valve has experienced 50 years in the development of international professional domain, and the occasion of application also more and more widely.Yet the research of servo valve also is in a relatively backward state at home, particularly the machining manufacture view of strength member is more outstanding, armature is had relatively high expectations in the part of electrohydraulic servo valve, and there is following defective in present domestic like product machining:
Mainly beat table line location by pincers worker, its characteristics: workload strengthens, inefficiency, and processing cost increases, output reduces, and precision is not high, and uniformity is poor, can not satisfy the existing market demand.
Summary of the invention
Technical problem to be solved by this invention provides armature centre of location anchor clamps in a kind of electrohydraulic servo valve, and it is low to have solved in the prior art working (machining) efficiency, the defective that precision is not high.
Technical scheme
The invention provides armature centre of location anchor clamps in a kind of electrohydraulic servo valve, comprise model drilling body, two locating pieces, cushion block and hold-down mechanisms, described model drilling body is " recessed " shape structure that both sides have the window that matches with locating piece, connecting between two windows is the cushion block installation position, and the model drilling body bottom is provided with support bracket fastened screwed hole; Described locating piece is installed in the window of offering the model drilling body both sides; Described cushion block is installed in the cushion block installation position that is provided with between model drilling body two windows, has two grooves of settling armature above it; Described armature is put into the cushion block groove, and locate with locating piece at two ends, has hold-down mechanism to compress above, thereby finishes the three-dimensional localization to armature.
Described hold-down mechanism comprises support, finger plate, support plate and eyelet bolt, and described support is fixed on the model drilling body, cooperates with finger plate, support plate, eyelet bolt to compress armature; Finger plate one end is fixed on the support, can be around its fixing point rotation, and the other end has the breach that cooperates with eyelet bolt, and the centre offers " one " word groove that cooperates with support plate; Support plate is fixed by bolts in " one " word groove of offering in the middle of the finger plate, and support plate can become level; Eyelet bolt one end is fixed on the support, can rotate around fixing point, and the breach of offering on the other end and the finger plate matches, and wing nut is housed on it.
Beneficial effect
Adopt in the electrohydraulic servo valve of the present invention armature to center and used anchor clamps, convenient mounting and clamping, simple wherein, resetting and rotating accuracy height, efficient height, cost are low.The centre bore position, armature two ends that is processed is correct, and high conformity has improved working (machining) efficiency greatly, has reduced the requirement to workman's technical merit.
