Description
Technical field
The present invention relates to a kind of attrition process clamping tool, be specifically related to a kind of attrition process clamping tool that is used for armature component of electrohydraulic servo valve.
Technical background
Electrohydraulic servo valve has experienced 50 years in the development of international professional domain, and the occasion of application also more and more widely.It is more outstanding that yet the research of electrohydraulic servo valve also is in machining, the manufacture view of relatively backward a state, particularly strength member at home.The processing method that is used for the used electro-hydraulic servo valve part armature component of electrohydraulic control system at present is: after earlier armature, pipe spring, feedback rod being processed, be press-fitted by the interference fit between armature center hub and the pipe spring, whether the assembling of check armature reaches specification requirement, regulates each relative dimensions by the processing method of grinding again and reaches specification requirement.Because relative size, the depth of parallelism, perpendicularity between armature and pipe spring and the feedback rod are had relatively high expectations, there is not a plane to can be used as the measuring basis plane because of armature and pipe spring again, measurement between armature and the pipe spring simultaneously is difficulty relatively, if there is not clamping tool, be difficult to measure accurately, even if can accurately measure, also need very big workload, to having relatively high expectations of testing staff, so that inefficiency, processing cost increase, and needs to consume the great amount of manpower resource.
Summary of the invention
The objective of the invention is to overcome the defective of prior art and a kind of attrition process clamping tool that is used for armature component of electrohydraulic servo valve is provided, its operability is good, measures easily and fast, good reproducibility, long service life has significantly reduced the workload of processing, and has improved working (machining) efficiency greatly.
The technical scheme that realizes above-mentioned purpose is: a kind of attrition process clamping tool that is used for armature component of electrohydraulic servo valve, described armature component is made up of armature, pipe spring and feedback rod, described armature has a center hub and the both sides head is a flat horizontal surface, described pipe spring is inserted in the center hub of armature and the symmetry that has central through hole and be positioned at the bottom is located at the installing hole of central through hole both sides, described feedback rod is inserted in the central through hole of pipe spring, described attrition process clamping tool comprises a base and a fixed block, its kind:
The upper surface central authorities of described base are provided with one and are used to place the groove that supports armature component, and the cell wall upper surface of this groove is used for flatly supporting the flat horizontal surface of armature;
The cross sectional shape of described fixed block is one to fall
Font, its height is more than or equal to managing the spring lower surface to the length between the feedback rod lower end, its upper surface central authorities are provided with one and are used for the perforation that feedback rod passes through and are provided with two installing hole respective threads holes with the pipe spring, and the screw that it passes the installing hole of pipe spring by two and screws in screwed hole is connected the lower surface of pipe spring and is suspended in the groove of base with armature component.
Above-mentioned a kind of armature component that is used for electrohydraulic servo valve grinds clamping tool, and wherein: the groove of described base is the one-level stepped groove, the degree of depth of this groove greater than the armature lower surface to the length between the feedback rod lower end.
The beneficial effect that is used for the attrition process clamping tool of armature component of electrohydraulic servo valve of the present invention is: simple to operate, easy to process, can reduce the great amount of manpower work, and cut down finished cost, can guarantee machining accuracy simultaneously.
Description of drawings
Fig. 1 is the attrition process clamping tool user mode cutaway view that is used for armature component of electrohydraulic servo valve of the present invention;
Fig. 2 is the attrition process clamping tool user mode vertical view that is used for armature component of electrohydraulic servo valve of the present invention.
The specific embodiment
The invention will be further described below in conjunction with accompanying drawing.
See also Fig. 1, the armature component of electrohydraulic servo valve that illustrates 3 among Fig. 1 is made up of armature 31, pipe spring 32 and feedback rod 33, and wherein, armature 31 has a center hub 310 and the both sides head is a flat horizontal surface 311; Pipe spring 32 is inserted in the center hub 310 of armature 31 and the symmetry that has central through hole 320 and be positioned at the bottom is located at the installing hole 321 of central through hole 320 both sides; Feedback rod 33 is inserted in logical 320 holes, center of pipe spring 32.
The attrition process clamping tool that is used for armature component of electrohydraulic servo valve of invention comprises a base 1 and a fixed block 2, wherein:
The upper surface central authorities of base 1 are provided with one and are used to place the groove 10 that supports armature component 3, and this groove 10 be the one-level stepped groove, and the degree of depth of this groove 10 arrives length between feedback rod 33 lower ends greater than armature 31 lower surfaces.The upper surface of these groove 10 cell walls is used for flatly supporting the flat horizontal surface 311 of armature 31;
The cross sectional shape of fixed block 2 is one to fall
Font, its height is more than or equal to managing spring 32 lower surfaces to the length between feedback rod 33 lower ends, its upper surface central authorities are provided with one and are used for the perforation 20 that feedback rod 33 passes through and are provided with two installing hole 321 respective threads holes 21 with pipe spring 32, and it is connected the lower surface of pipe spring 32 by two screws 4 installing hole 321 and that screw in screwed hole 21 that pass pipe spring 32 and is suspended in the groove 10 of base 1 with armature component 3.Fixed block 2 be used for No. 3 clampings of armature component to reduce unnecessary error.
See also Fig. 2 again, the flat horizontal surface 311 of armature 31 both sides heads is the face of the attrition process of wanting among the figure, because the quality of these flat horizontal surface 311 crudies is the quality of the properties of product of the whole electrohydraulic servo valve of influence directly, the required precision that is exactly this flat horizontal surface 311 in addition is than higher, difficulty of processing is very big, and is therefore just very high to its processing method and the requirement of machining tool.After armature component 3 and fixed block 2 connect, when lying in base 1 upper surface pipe spring 32 and feedback do 3 and fixed block 2 just in time be placed in the groove 10 of base 1, can prevent to manage be damaged with contacting of other objects variation with the position of spring 32.The armature component 3 that fixes just can lie in and carry out attrition process on the base 1.After the flat horizontal surface 311 for the treatment of armature 31 1 side heads processes, base 1 is changeed an angle, can process the flat horizontal surface 311 of armature 31 opposite side heads.The effect of fixed block 2 is after treating that the both sides head flat horizontal surface of armature 31 311 is ground, to take the depth of parallelism that detection platform gets on to check two flat horizontal surface 311 of armature 31 together with armature component 3.
Above embodiment is only for the usefulness that the present invention is described, but not limiting the scope of the invention.Relevant those skilled in the art under the situation that does not break away from the spirit and scope of the present invention, can also make various conversion or modification, and the technical scheme that all are equal to also should belong within the category of the present invention's protection, is limited by each claim.
