Abstract
The utility model relates to a fixture for processing working air gaps of a torque motor of a servo valve in a linear cutting manner. An armature component (6) of the motor is fixed on a primary seat (2), magnetic steel (8) is supported between upper and lower magnetizers (7), a press plate (9) is pressed at the outer ends of the magnetizers (7), the press plate (9), the upper and lower magnetizers (7) and the magnetic steel (8) are tightly connected integrally via screws (10) so as to form an incomplete torque motor, a cushion block (1) of the fixture is fixed on the bottom surface of the primary seat (2) of the torque motor, a limiting block (3) used for adjusting the radial position and the axial position of the torque motor is connected onto the rear end surface of the cushion block (1), and a side surface of the limiting block (3) clings to a side surface of the primary seat (2) of the torque motor. By the aid of the fixture, air gaps of four motors can be obtained uniformly without reducing performances of the torque motor, the fixture has higher efficiency compared with other processing modes, and uniformity of products is guaranteed.
Description
Technical field
The utility model belongs to the clamping tool for machine work that relates to a kind of accurate finding, particularly relates to a kind of anchor clamps that are used for line cutting processing servo valve torque-motor working gas gap.
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.Torque-motor as electrohydraulic servo valve is the prestage of servo valve, is the most important parts that influence the static state and the dynamic property of servo valve.
Torque-motor provides servo valve by the power resources of control elements valve core movement and control, directly influences the static state and the dynamic property of big servo valve.Wherein the performance of torque-motor depends on precision and the symmetry with armature and magnetic conductor working gas gap to a great extent again.
For a long time, because the working gas gap of servo valve torque-motor is to the importance of properties of product influence, processing this air gap all realizes by precise finiss, but grinding efficiency is very low, and be difficult to guarantee consistency of product, so the working gas gap of processing torque-motor becomes a bottleneck of servo valve production efficient.
Summary of the invention
Technical problem to be solved in the utility model provides a kind of anchor clamps that can improve the air gap that is used for line cutting processing torque-motor of servo valve production efficiency.
The technical scheme that its technical problem that solves the utility model adopts is: a kind of anchor clamps that are used for line cutting processing servo valve torque-motor working gas gap are provided, described torque-motor contains armature component, magnet steel, on, following magnetic conductor, the one-level seat, screw and pressing plate, described anchor clamps are made up of cushion block and limited block, the armature component of described torque-motor is fixed on the one-level seat, described magnet steel is supported on, between the following magnetic conductor, described pressing plate be pressed in the magnetic conductor outer end and by screw with pressing plate, on, following magnetic conductor and magnet steel link into an integrated entity tightly and form incomplete torque-motor; The cushion block of described anchor clamps is fixed on the one-level seat bottom surface of torque-motor; The described limited block that is used to adjust torque-motor radial position and axial location is connected on the cushion block rear end face and the one side is close to the side of the one-level seat of torque-motor.
Beneficial effect:
The anchor clamps that are used for line cutting processing servo valve torque-motor working gas gap of the present utility model have been adopted, make servo valve torque-motor working gas gap can adopt the processing method of line cutting, and processing method by the line cutting, can obtain the air gap of four torque-motors equably and do not reduce the performance of torque-motor, and the processing mode than other has had higher efficient, has guaranteed consistency of product again.
