Specific implementation mode

The utility model is described in detail below in conjunction with attached drawing.As shown in Figure 1 to Figure 3.

Embodiment：A kind of spark machine that machining accuracy is stablized, including main shaft 1,1 lower end of main shaft are connected with stationary fixture 2, institute It includes horizontal connection block 22 to state stationary fixture 2, and one end of horizontal connection block 22 is equipped with geometrical clamp 21, and 22 activity of horizontal connection block is even Be connected to adjusting folder 23, adjust folder 23 can relative level link blocks 22 move, adjust folder 23 and be connected with and adjust folder 23 for driving and move Dynamic driving structure is clamped with electrode block 3 between geometrical clamp 21 and adjusting folder 23, the upper end of the electrode block 3, which is equipped with, to be clamped Portion 41, the geometrical clamp 21 are equipped with n master positioning hole 212, and clamped portion 41 is equipped with close to the side of geometrical clamp 21 and master positioning 212 matched master positioning block 32 of hole adjusts folder 23 and is equipped with m secondary location hole, is clamped portion 41 close to the side for adjusting folder 23 Equipped with the matched secondary locating piece of secondary location hole, n, m>2.

The technical program is fixed electrode block 3 with fixture by the way of locating piece and location hole cooperation；Master positioning block 32 It is all higher than with secondary locating piece or equal to 3, n, m is natural number, since the precision of processing is relatively low, master positioning block 32, secondary locating piece The point projected on contact plane, will not point-blank, i.e., at least 3 points are not conllinear so that electrode block 3 with it is solid When clamp 21, adjusting 23 contact of folder, it is 3 points or more and contacts, and is not conllinear；Connect to effectively fix electrode block 3 and fixture It connects, avoids the problem that fixture because of flatness, cause bite less and the shaking of generation.

Preferably, the cross section of the master positioning block 32 or secondary locating piece is arranged in polygon.

After the cross section of master positioning block 32, secondary locating piece is arranged in polygon, electrode block 3 and master positioning block 32, pair are fixed Contact between the block of position is Multi-contact, is further limited electrode block 3.

Further, the clamping face of geometrical clamp 21 be equipped with plurality of guiding gutter 211, adjust folder 23 clamping face also be provided with it is a plurality of Diversion trench 211；Diversion trench 211 is in be vertically arranged.

It is closely acted in working solution for electrode block 3, avoids geometrical clamp 21, adjusts remaining working solution on folder 23, therefore set Diversion trench 211 has been set, working solution is facilitated to flow out.

Further, the lower end of the horizontal connection block 22 is equipped with guide groove 221, and guide groove 221 is dovetail-shape or T shapes, The upper end of the electrode block 3 be equipped with 221 matched guide pad of guide groove, the driving structure include be arranged in guide groove One end of leading screw in 221, lead screw 25 is flexibly connected with the end of guide groove 221, and lead screw 25 can 22 turns of relative level link block Dynamic, the guide pad is equipped with threaded hole and is threadedly coupled with lead screw 25.

Folder 23 is adjusted by the way that guide pad is arranged along 221 displacement of guide groove, and driven using lead screw 25, passed through Rotary screw 25 adjustment adjust folder 23 position, and then realize to adjust folder 23 adjusting, secondly guide groove 221 it is dovetail-shape or T shapes so that guide pad is limited in guide groove 221, and weight is born by horizontal connection block 22, bears to adjust folder without lead screw 25 23 weight.Lead screw 25 can be connect by bearing block with horizontal connection block 22.

Further, the end face of the horizontal connection block 22 is connected with for limiting the limited block for adjusting 23 movings range of folder 24, the limited block 24 includes the fixed part 241 being connect with the end face of horizontal connection block 22,241 company of having extended downwardly of fixed part Socket part 242, interconnecting piece 242 are connected with limiting section 243, and fixed part 241 is identical as the length direction of limiting section 243, and limiting section 243 length is more than the length of fixed part 241, and fixed part 241 is equipped with connection through-hole and passes through connector and horizontal connection block 22 It is fixedly connected, the axis shortest distance of limiting section 243 to connection through-hole is more than the distance of intersecting point under axis to end face.

Limited block 24 can be used screw or be bolted in the end face of horizontal connection block 22, and limited block 24 can be around screw, spiral shell Bolt rotates, since the axis shortest distance of limiting section 243 to connection through-hole is more than axis to the distance of end face intersecting point, limit It position portion 243 can be in the both sides of end face（Side and bottom side）It is mobile, when needing limit, connector is unclamped, limiting section 243 is rotated To lower section, it is located on the track for adjusting folder 23, then tightens connector；When that need not limit, connector is unclamped, limiting section 243 rotations leave the track for adjusting folder 23, then tighten connector to side.It can be with active process limited block 24.

Further, the end face of limiting section 243 be equipped with threaded hole, and limiting section 243 by threaded hole be threaded with to Socket part.

In specific setting, it is screw rod that one end of abutting part, which is equipped with, or ground socket part is screw rod, is connected with 243 screw thread of limiting section It connects, so as to adjust abutting part to the distance of interconnecting piece 242, distance is regulated and after electrode block 3 is clamped when adjusting folder 23, The rotation of limited block 24 to limiting section 243 is located at lower section, then adjusts abutting part so that abutting part is abutted with folder 23 is adjusted, and is prevented Folder 23 is adjusted to loosen.Preferably, folder 23 is adjusted to be provided with and the matched jack of abutting part.

The above content is only the preferred embodiment of the utility model, for those of ordinary skill in the art, according to this reality With novel thought, there will be changes in the specific implementation manner and application range, and the content of the present specification should not be construed as Limitations of the present invention.
