Abstract
The invention discloses a clamp used for linearly cutting and processing a working air gap of a moment motor of a servo valve; wherein, the gag bit component of the moment motor is fixed on a first grade seat; an alnico is supported between an upper magnetizer and a lower magnetizer; a pressure pad is pressed on the outer ends of the magnetizers and is closely connected the pressure pad, the upper magnetizer, the lower magnetizer and the alnico in a whole to form an incomplete moment motor; the clamp consists of a cushion block and a limitation block; wherein, the cushion block of the clamp is fixed on the bottom surface of the first grade seat of the moment motor; the limitation block used for adjusting the radial position and the axial direction of the moment motor is connected at the back end surface of the cushion block and one side surface of the limitation block closely clings to the side surface of the first grade seat of the moment motor; the air gaps of four moment motors can be uniformly obtained by adopting the clamp of the invention and by the processing method of linearly cutting without reducing the property of the moment motors; besides, the invention has higher efficiency than other processing modes and ensures the consistency of a product.
Description
Technical field
The present invention relates to a kind of clamping tool for machine work of accurate finding, relate in particular 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 the precision and the symmetry of 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 very under, 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
The objective of the invention is to solve the problems referred to above that prior art exists, 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 are provided.
The objective of the invention is to be achieved by following technical scheme: a kind of anchor clamps that are used for line cutting processing servo valve torque-motor working gas gap, described torque-motor contains armature component, magnet steel, upper and lower magnetic conductor, one-level seat, screw and pressing plate.Described anchor clamps are made up of cushion block and limited block.Wherein, the armature component of described torque-motor is fixed on the one-level seat, described magnet steel is supported between the upper and lower magnetic conductor, and described pressing plate is pressed in the magnetic conductor outer end and by screw pressing plate, upper and lower magnetic conductor and magnet steel is linked into an integrated entity tightly forms 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.
The anchor clamps that are used for line cutting processing servo valve torque-motor working gas gap of the present invention 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.
Description of drawings
Provide the specific embodiment of the present invention below in conjunction with accompanying drawing:
Fig. 1 is the structural representation that is used for the anchor clamps of line cutting processing servo valve torque-motor working gas gap of the present invention.
The specific embodiment
See also Fig. 1, the anchor clamps that are used for line cutting processing servo valve torque-motor working gas gap of the present invention, torque-motor wherein contains armature component 6, magnet steel 8, upper and lower magnetic conductor 7, one-level seat 2, screw 10 and pressing plate 9.Wherein, the armature component 8 of torque-motor is fixed on the one-level seat 2; Magnet steel 8 is supported between the upper and lower magnetic conductor 7; Pressing plate 9 is pressed in down magnetic conductor 7 outer ends and by screw 10 pressing plate 9, upper and lower magnetic conductor 7 and magnet steel 8 is linked into an integrated entity tightly forms incomplete torque-motor; Working gas gap to be processed is the gap between the composition surface, armature 60 two ends in upper and lower magnetic conductor 7 and the armature component 6.
Anchor clamps are made up of cushion block 1 and limited block 3.Wherein the cushion block 1 of anchor clamps is fixed on one-level seat 2 bottom surfaces of torque-motor;
Be placed in wire cutting machine tool with installing the anchor clamps integral body that is used for line cutting processing servo valve torque-motor working gas gap of the present invention, by the datum level location benchmark processing of cushion block 1.The air gap value δ that requires according to torque-motor processes this air gap with the method for line cutting.
Those of ordinary skill in the art will be appreciated that, above embodiment is used for illustrating the present invention, and be not to be used as limitation of the invention, the present invention can also change and more mode, as long as in connotation scope of the present invention, all will drop in claims scope of the present invention variation, the modification of the above embodiment.
