Background

The spark machine is a mechanical processing device and is mainly used for electric spark processing. The special machining method is widely applied to the manufacture of various metal dies and mechanical equipment, and is a special machining method for corroding and removing a conductive material by utilizing the electric corrosion effect generated during pulse discharge between two electrodes immersed in working liquid, and is also called as electric discharge machining or electric corrosion machining. When the electric spark machining is carried out, a tool electrode and a workpiece are respectively connected with two poles of a pulse power supply and immersed into working liquid, or the working liquid is filled into a discharge gap, the tool electrode is controlled by a gap automatic control system to feed to the workpiece, when the gap between the two electrodes reaches a certain distance, pulse voltage applied to the two electrodes breaks down the working liquid to generate spark discharge, however, the spark machine in the prior art has certain defects, for example, because the equipment is large, the machine head often exceeds the stroke in the movement process and cannot be machined, particularly, the stroke is severely limited, and further improvement is needed.

and one end of the electrode rod is provided with an external thread connected with the second threaded hole, and the other end of the electrode rod is used for connecting an electrode.

Compared with the prior art, an extend tool for spark machine can adjust the length that extends the tool horizontal direction through removing the telescopic link according to the processing demand, adjust the height that extends the tool vertical direction through the rotating electrode pole to the problem of spark machine equipment processing stroke restriction has been solved. In addition, considering the processing problems of high difficulty, low processing precision and the like of directly processing the telescopic hole for sliding the telescopic hole on the extension bracket in actual processing, the extension bracket and the telescopic rod are connected through the connecting piece, the length of the connecting piece is short, and the processing problems can be effectively solved. In addition, the production efficiency can be greatly improved by producing the extension bracket with uniform length and the connecting pieces with different lengths, and the jig is favorable for batch production and production standardization. Meanwhile, the positioning shaft is matched with the positioning hole, so that the connecting piece is fixedly connected with the extension support conveniently.

Furthermore, a reinforcing rod is further arranged on the extension support, and the reinforcing rod and the extension support form a right-angled triangle. The included angle between the reinforcing rod and the extension support, which is far away from the main shaft of the spark machine, is 3-10 degrees. Adopt above-mentioned technical scheme, help preventing to extend the support and take place comparatively serious deformation.

Further, the end face of the connecting piece with the positioning hole extends to the outer side of the end face of the extending support with the positioning shaft. By adopting the technical scheme, the welding is convenient, and meanwhile, the manufacturing cost can be reduced. If the end face of the extension bracket is large, the overall volume of the extension bracket is large. Compared with the scheme that the end face of the connecting piece is larger, the scheme that the end face of the extension bracket is larger needs more materials, and the manufacturing cost is higher.

Further, the axis of the first threaded hole is perpendicularly intersected with the axis of the telescopic hole. Adopt above-mentioned technical scheme, help fixing the position of telescopic link.

Furthermore, one end of the telescopic rod, which is far away from the connecting piece, is provided with a mounting seat with a through hole, the mounting seat is provided with a nut, and a threaded hole of the nut corresponds to the through hole. Because the length of telescopic link is longer, so it is not very convenient to process the screw hole on the telescopic link. By adopting the technical scheme, the second threaded hole is conveniently processed at the extending end of the telescopic rod,

further, the other end of the electrode rod is connected with the electrode through threads. By adopting the technical scheme, the electrode is convenient to replace, and the jig is favorable for adapting to different application situations.

For a better understanding and an implementation, the present invention is described in detail below with reference to the accompanying drawings.

The extension bracket 100 is an L-shaped extension bracket 100, one end of which can be inserted into the main shaft of the spark machine, and the other end of which is fixedly connected with the connecting piece 200. The telescopic rod 300 is sleeved in the connecting piece 200, and the telescopic rod 300 slides in the connecting rod. One end of the electrode rod 400 is connected to the extension end of the telescopic rod 300, and the other end thereof is connected to the electrode 500.

Referring to fig. 1-4, the extension bracket 100 includes a short axis 110 and a long axis 120. One end of the short shaft 110 may be inserted into a main shaft of a spark machine, and the other end thereof is connected to the long shaft 120 to form an L-shape. Specifically, the axis of the stub shaft 110 is collinear with the axis of the main shaft of the spark machine, and the axis of the stub shaft 110 perpendicularly intersects the axis of the long shaft 120. In actual manufacturing, the short axis 110 and the long axis 120 are integrally formed in this embodiment. Because the stent extender 100 is integrally formed and has a long overall length, in order to prevent the stent extender 100 from being deformed seriously, a reinforcing rod 130 is further disposed between the short shaft 110 and the long shaft 120, one end of the reinforcing rod 130 is welded to the short shaft 110, the other end of the reinforcing rod 130 is welded to the long shaft 120, and the short shaft 110, the long shaft 120 and the reinforcing rod 130 form a right triangle together. The angle between the stiffener 130 and the long axis 120 is 3 to 10 degrees, and in the present embodiment, the angle between the stiffener 130 and the long axis 120 is 5 degrees. To facilitate the fixed connection of the connector 200 to the extension bracket 100, the end surface of the long shaft 120 away from the short shaft 110 is provided with a positioning shaft 121. The end face of the positioning shaft 121 is located in the region of this end face, and the axis of the positioning shaft 121 is perpendicular to this end face.
