Description
Technical field
This utility model belongs to micro EDM field, is specifically related to a kind of microsphere spark machined clamping device.
Background technology
In inertial confinement fusion is studied, needing at metallic hollow microsphere Surface Machining micropore, spark machined is micropore
The common method of processing, and the clamping of microsphere is a very difficult problems, to be fixed, ensure that surface quality is not broken
Bad, guarantee electric conductivity and want easy centering.The method using conductive adhesive before, this method degumming is the most difficult,
Easily injuring part, microsphere and base are point cantact, and work in-process part is susceptible to displacement or disengaging, and electric conductivity
Poor, centering is the most difficult, have impact on crudy and the working (machining) efficiency of workpiece.
Summary of the invention
In order to overcome in prior art, microsphere part electrical spark machining clamping is difficult, be not easy the deficiency of centering.This practicality
Novel offer one microsphere is used for spark machined clamping device, changes past point cantact into present linear contact lay, improves micro-
The electric conductivity of ball.Microsphere part can not only be fixed and by easy centering, clamping easily, meet electric spark fine by this device
The requirement of processing.It is particularly well-suited to the clamping of diameter 0.5mm to 3mm conductive micro-balloons.
The technical solution of the utility model is as follows:
Of the present utility model a kind of clamp the microsphere device for spark machined, be characterized in, described clamping dress
Putting containing base, pressure cap, described pressure cap is hollow cylinder, and the end face axis of pressure cap is provided with trapezoid through hole, pressure cap
Bottom is provided with female thread.Described base is cylinder, and the axis, upper surface of base is provided with inverted trapezoidal blind hole, base
Stage casing is provided with external screw thread.Microsphere to be processed is placed in the inverted trapezoidal blind hole of base；Described base rotates through at the bottom of pressure cap
Portion, the external screw thread of base cooperates with the female thread of pressure cap.Described microsphere is by the inverted trapezoidal blind hole of base and pressure cap
Trapezoidal hole clamps.
The diameter of described pressure cap female thread is less than the internal diameter of pressure cap.
The externally threaded diameter of described base is more than the diameter of base.
Described base and pressure cap are that concentric is arranged；Trapezoid through hole and inverted trapezoidal blind hole are that concentric is arranged.
When pressure cap clamping microsphere part, owing to microsphere XY direction degree of freedom is limited by base center inverted trapezoidal blind hole
System, the inverted trapezoidal blind hole of center when pressure cap rotates, microsphere Z-direction degree of freedom is limited, owing to being trapezoidal hole, can clamp
The microsphere of different-diameter.
Microsphere spark machined clamping device simple in construction of the present utility model, easy and simple to handle, cost of manufacture is low, it is adaptable to
The clamping of various different-diameter microspheres, is particularly well-suited to the clamping of diameter 0.5mm to 3mm conductive micro-balloons.

Detailed description of the invention
Below in conjunction with the accompanying drawings this utility model is described specifically:
Embodiment 1
Fig. 1 is microsphere spark machined clamping device structural representation of the present utility model, and Fig. 2 is in this utility model
Pressure cap structural representation, Fig. 3 is the understructure schematic diagram in this utility model.In Fig. 1 ~ Fig. 3, one of the present utility model
Microsphere spark machined clamping device, containing base 1, pressure cap 2, described pressure cap 2 is hollow cylinder, in the end face of pressure cap 2
Axis is provided with trapezoid through hole 4, is provided with female thread bottom pressure cap 2.Described base 1 is cylinder, the upper surface of base 1
Axis is provided with inverted trapezoidal blind hole 5, and the stage casing of base 1 is provided with external screw thread.Microsphere to be processed is placed in the inverted trapezoidal of base 1
In blind hole 5.Described base 1 rotates through bottom pressure cap 2, and the external screw thread of base 1 cooperates with the female thread of pressure cap 2.Institute
The microsphere 3 stated is clamped by the trapezoid through hole 4 of the inverted trapezoidal blind hole 5 of base 1 with pressure cap 2.
The diameter of described pressure cap 2 female thread is less than the internal diameter of pressure cap 2.
The externally threaded diameter of described base 1 is more than the diameter of base 1.
Described base 1 is arranged for concentric with pressure cap 2；Trapezoid through hole 4 is arranged for concentric with inverted trapezoidal blind hole 5.
In the present embodiment, a diameter of 1 mm of microsphere 3, base 1 is made up of the plastics that hardness is relatively low, and pressure cap 2 uses electric conductivity
Can make by metal material good, that hardness is low.
In this utility model, microsphere 3 being put into the inverted trapezoidal blind hole 5 of base 1, rotating metallic pressure cap 2 is fixed；Utilize
Trapezoid through hole 4 in the inverted trapezoidal blind hole 5 of base and pressure cap, is fixed on microsphere 3 on clamping device, makes microsphere 3 in processing
In be not subjected to displacement and be in conduction state with lathe.Then it is loaded into spark-erosion machine tool is processed.
When pressure cap clamping microsphere part, owing to microsphere XY direction degree of freedom is limited by base center inverted trapezoidal blind hole
System, the inverted trapezoidal blind hole of center when pressure cap rotates, microsphere Z-direction degree of freedom is limited, owing to being trapezoidal hole, can clamp
The microsphere of different-diameter.
