Abstract
The utility model discloses a kind of electrical discharge machining positioning fixtures, including positioning plate, fixed plate, setting location hole in the positioning plate；Setting and the corresponding mounting hole of the location hole in the fixed plate；The fixed plate passes through screw lock with positioning plate.It in electric spark machining field, by the combination of fixed plate and positioning plate, solves the problems, such as that workpiece easily deviates in process, and can further realize the batch positioning of multiple workpiece, improve production efficiency.
Description
Technical field
The utility model relates to electric spark machining field, more particularly to a kind of electrical discharge machining positioning fixture.
Background technology
Electrical discharge machining is generated using the pulsed discharge of the conductive electrode being immersed in working solution and two interpolar of electrically conductive workpiece
Galvanic action, which carrys out ablation workpiece (being as shown in Figure 1 workpiece schematic diagram), needs the position processed.It is extremely important in electrical discharge machining
Link be to position workpiece, entire position fixing process is divided into three steps：The first step, the clamping of electrode and correction, electrode pass through screw
It is locked on spark machine main shaft, is then corrected using amesdial, it is ensured that electrode, electrode vertical with board surface when moving up and down
It is parallel with board surface in side-to-side movement.Workpiece bottom, then profit is sucked in second step, the clamping of workpiece and correction, magnetic platform
It is positioned with amesdial, but the base area of workpiece is smaller, it will usually a circle glue is coated in contact site to reinforce.The
Three steps, the positioning of electrode opposite piece, this step requires the center of electrode to be aligned with the center of workpiece, so can pass through electrode and work
The mode that part side is collided finds the central point of workpiece, adjusts electrode further according to physical size known to workpiece, it is ensured that electrode
Center be aligned with the center of workpiece.
The process of positioning decides the precision of workpiece, and each workpiece is required for individually processing, and if the workpiece in processing
It shifts, needs repositioning primary.The serious forgiveness of processing is low, and time cost is high, and enterprises production efficiency is low.
Therefore, it is necessary to a kind of locating clip that can position and can securely fix workpiece in batches is proposed regarding to the issue above
Tool.
Utility model content
The technical problem to be solved by the present invention is to provide a kind of electrical discharge machining positioning fixtures, can position work in batches
Part, and workpiece will not shift in process.
In order to solve the above-mentioned technical problem, the technical solution of the utility model is：
A kind of electrical discharge machining positioning fixture, including positioning plate, fixed plate, setting location hole in the positioning plate；It is described
Setting and the corresponding mounting hole of the location hole in fixed plate；The fixed plate passes through screw lock with positioning plate.
Further, the lower surface of the positioning plate and the upper surface plane-plane contact of the fixed plate.
Further, the cross section of the positioning plate is projected as circle；The cross section of the fixed plate is projected as circle；It is described
The lower surface of positioning plate is identical with the upper surface diameter of the fixed plate.
Further, the location hole runs through the positioning plate plate body, is processed by slow wire feeding.
Further, the mounting hole is set as counter sink, including workpiece mounting hole and clamp-securing bore.
Further, the location hole is evenly distributed on inside positioning plate plate body；The distribution mode of the clamp-securing bore with
The location hole is corresponding.
Compared with prior art, a kind of electrical discharge machining positioning fixture provided by the utility model, is set in positioning plate
Location hole；Setting and the corresponding mounting hole of location hole in fixed plate；Fixed plate passes through screw lock with positioning plate.Pass through positioning
Hole positions workpiece, and positioning plate is locked with fixed plate, and fixed plate is adsorbed on magnetic platform, and workpiece is made not occur in processing
Offset；Location hole can be needed according to production and actual conditions set several, and the batch of multiple workpiece is facilitated to position, is improved
Production efficiency.

Specific embodiment
Specific embodiment of the present utility model is described further below in conjunction with the accompanying drawings.It should be noted that
The explanation of these embodiments is used to help to understand the utility model, but do not form the restriction to the utility model.This
Outside, technical characteristic involved in the various embodiments of the present invention described below is as long as they do not conflict with each other
It can be combined with each other.
As shown in Figures 2 to 4：A kind of electrical discharge machining positioning fixture including positioning plate 1, fixed plate 2, is set in positioning plate 1
Location hole 11；Setting and 11 corresponding mounting hole of location hole in fixed plate 2；Fixed plate 2 passes through screw lock with positioning plate 1.
Workpiece bottom shown in Fig. 4 is inserted into location hole, screw is then locked by fixed plate bottom, fixture is placed on magnetic flat
On platform, will firmly it be adsorbed.
The lower surface of positioning plate 1 and the upper surface plane-plane contact of fixed plate 2 ensure that positioning plate 1 is put down with fixed plate 2 with magnetism
Platform keeping parallelism.Positioning plate is just high with the depth of parallelism of fixed plate in itself, and the fixture fixed is only needed with amesdial trimming precision.
The cross section of positioning plate 1 is projected as circle；The cross section of fixed plate 2 is projected as circle；The lower surface of positioning plate 1 with
The upper surface diameter of fixed plate 2 is identical.Fixed plate may be arranged as the gengon of rule, be on the one hand to be suitble to processing,
On the other hand it is to calibrate for convenience.
Location hole 11 runs through 1 plate body of positioning plate, is processed by slow wire feeding.Location hole is identical with the size of workpiece, so as to work
Location hole 11 is inserted into part bottom, and workpiece is positioned more secured.
Mounting hole is set as counter sink, including workpiece mounting hole 22 and clamp-securing bore 21.Adjoining clips location hole 21 it
Between radian for π/3, in order to easy to process, positioning plate 1 is also made to be connect with fixed plate 2 more secured.Location hole 11 uniformly divides
Cloth is inside positioning plate plate body；The distribution mode of clamp-securing bore 21 is corresponding with location hole 11.
The embodiment of the utility model is explained in detail, but the utility model is not limited to be retouched above in association with attached drawing
The embodiment stated.For a person skilled in the art, it is right in the case where not departing from the utility model principle and spirit
These embodiments carry out a variety of change, modification, replacement and modification, still fall in the scope of protection of the utility model.
