Abstract
The invention relates to a laser welding jig for an electro-hydraulic servo valve armature component (assembly), comprising a revolving block (2) and two components for a movable fixed support (1). The revolving block is provided with an upper surface and a lower surface which are parallel, a vertical through hole in the center, and a column-shaped lug on the lower surface. The movable fixed support (1) is provided with a hole in the center matched with the cylindrical lug clearance of the lower surface of the revolving block (2). The upper surface of the movable fixed support is smoother than that of the lower surface. The invention has the advantages of simple structure, low cost, adjustability, high positioning precision, strong operability and practicability and convenient clamping of the iron components (assembly) on the jig, convenient operation for workers, improved processing efficiency, reduced processing time, capability of processing components which exceed the tolerance, and saved processing cost.
Description
Technical field
The invention belongs to the clamping tool for machine work field, particularly relate to a kind of laser welding clipper of electro-hydraulic servo valve armature iron component.
Background technology
Electrohydraulic servo valve is a kind of high accuracy that is used for electrohydraulic control system, the electro-hydraulic servo control assembly with very high dynamic response, and it can be used for the hydraulic control system of accurate displacement, speed, power and acceleration.Armature component is the core Control Component of electrohydraulic servo valve, and whole assembly all is an exotic material through high-accuracy processing repeatedly.Whether the assembly welding successfully is directly connected to electrohydraulic servo valve precision, every important parameters index, impact resistance and service life.Strict positioning and clamping, rotation that past adopts have a lot of shortcomings with motor control method, and clamping complexity, weld assembly position point required precision height, welding back assembly are easy to generate distortion, laser and workpiece complexity, the narrow shortcomings such as (frock can only be welded a kind of workpiece) of use face.
Summary of the invention
Technical problem to be solved by this invention provides a kind of laser welding clipper of electro-hydraulic servo valve armature iron component, has solved clamping complexity in the prior art, the high defective of weld assembly position point required precision.
Technical scheme
The invention provides a kind of laser welding clipper of electro-hydraulic servo valve armature iron component, comprise spill spin block, two parts of movable fixed bearing, described spill spin block is that upper and lower faces has vertical through hole for the parallel surface center, lower surface has cylindrical projection, there is the little matched in clearance of cylindrical projection of a hole and described spill spin block lower surface at described movable fixed bearing center, and described movable fixed upper surface of support fineness will be higher than lower surface.
Described movable fixed upper surface of support fineness is 0.5～1, and lower surface fineness is 3～3.5.
Spill spin block is connected by the little matched in clearance of axle with the hole with workpiece, in not constraint of direction of rotation, leans on the frictional force of workpiece and spill spin block upper surface to guarantee to rotate.
The movable fixed bearing can move and be bigger with the frictional force of whole welding bench, no matter the time be to weld in batch in welding, still single welds and all can easily use, and has greatly reduced the difficulty of laser and workpiece alignment.
It is to owe the location that workpiece is placed, and places easily easily, for the workpiece that has processing itself that error arranged also light clamping and do not influence machining accuracy.
Beneficial effect
Adopted the laser welding clipper of electro-hydraulic servo valve armature iron component that is used for of the present invention, make things convenient for clamping workpiece to improve working (machining) efficiency, and anchor clamps do not apply active force to workpiece in welding process, and welding is not easy to produce distortion, guarantees that simultaneously the multiple clamping positioning accuracy is in the scope that requires.The frame for movement of whole anchor clamps and machining accuracy all adopt fairly simple mode, we can say and have used the simplest method and ingenious structure thereof to accomplish the requirement that high-accuracy clamp just can reach.

Fig. 1 armature component of electrohydraulic servo valve structural representation;
The front view of the structural representation that Fig. 2 the present invention and armature component assemble;
The vertical view of the structural representation that Fig. 3 the present invention and armature component assemble.
The specific embodiment
Below in conjunction with specific embodiment, further set forth the present invention.Should be understood that these embodiment only to be used to the present invention is described and be not used in and limit the scope of the invention.Should be understood that in addition those skilled in the art can make various changes or modifications the present invention after the content of having read the present invention's instruction, these equivalent form of values fall within the application's appended claims institute restricted portion equally.
As shown in Figure 1, a kind of armature component of electrohydraulic servo valve comprises baffle feedback lever 11, armature 12 and pipe spring 13, and fixture for laser welding comprises spill spin block 2 and movable fixed bearing 1 wherein:
It is the 45# steel that movable fixed is propped up seat material, and it is good through modified wearability, and upper surface fineness reaches Ra0.5, lower surface fineness reaches Ra3.0, make spill spin block can easily rotate in the above and whole anchor clamps can not move, the axle of endoporus and spill spin block expenditure is connected horizontal direction quality of fit height, but rotation is wanted easily mutually.
The spill spin block material is QSn6.5-0.1 (tin bronze), and hardness ratio is lower, the workpiece of can not damaging, wear-resistant, friction, lubrication good.Workpiece is played the centralized positioning effect, the movable fixed bearing is played the connection effect.
Because welding is shaped as a circle, and welding requirements does not have distortion and internal stress is little, and the actual conditions (front is just carried out interference to workpiece and is press-fitted, and slight deformation is arranged) be convenient to each part of these anchor clamps are adjusted the location of workpiece like this.
It is the 45# steel that movable fixed is propped up seat material, and it is good through modified wearability, and upper surface fineness reaches Ra1, lower surface fineness reaches Ra3.5, make spill spin block can easily rotate in the above and whole anchor clamps can not move, the axle of endoporus and spill spin block expenditure is connected horizontal direction quality of fit height, but rotation is wanted easily mutually.
It is the 45# steel that movable fixed is propped up seat material, and it is good through modified wearability, and upper surface fineness reaches Ra0.8, lower surface fineness reaches Ra3.2, make spill spin block can easily rotate in the above and whole anchor clamps can not move, the axle of endoporus and spill spin block expenditure is connected horizontal direction quality of fit height, but rotation is wanted easily mutually.
