[0002] CNC EDM small hole machine, also known as EDM drilling machine or EDM fine hole discharge machine, is a precision processing equipment, mainly used for processing fine holes in super-hard steel, cemented carbide, copper, aluminum and any conductive material. The guide is a mechanical device and electronic component used to adjust or control various parameters of the system to ensure the stability and accuracy of operation.

DETAILED DESCRIPTION

[0020] The technical solution of the present invention is further described below with reference to the accompanying drawings and embodiments.

[0021] like Figure 1-Figure 3 As shown, the embodiment of the utility model proposes a twisting tool for the electrode wire guide of a CNC electric spark small hole machine, comprising:

[0022] The cam 1 is provided with a two-way threaded rod 4 on the upper surface of the base 1, and the two-way threaded rod 4 is rotatably connected to the two side walls of the support plate 2 through a bearing. Two limiting slide grooves 5 are provided on the upper surface of the support plate 3, and the limiting sliders 6 are slidably connected in the two limiting slide grooves 5. The threaded sections of the two-way threaded rod 4 with opposite thread directions are threaded with nuts 7. The bottom ends of the two limiting sliders 6 are respectively fixedly connected to the side walls of the two nuts 7, and the side walls of the two limiting sliders 6 close to one side are fixedly connected with an arc splint 8. A knob is fixedly connected to either end of the two-way threaded rod 4 for easy operation by the staff. The side walls of the two limiting sliders 6 are respectively fitted with the inner walls of the two limiting slide grooves 5, so that the horizontal fixing assembly runs smoothly.

[0023] The vertical fixing assembly is arranged above the supporting plate 3. The vertical fixing assembly includes a fixing plate 9 fixedly connected to the upper surface of the supporting plate 3. The side wall of the fixing plate 9 is fixedly connected to the mounting plate 10. The upper surface of the mounting plate 10 is provided with a threaded through hole 11. The threaded through hole 11 is internally threaded with a fixing threaded rod 12. The bottom end of the fixing threaded rod 12 is rotatably connected to an arc pressure plate 13. The top end of the fixing threaded rod 12 is fixedly connected to a knob for convenience of operation by the staff. The mounting plate 10 and the fixing plate 9 are in a vertical positional relationship, and the fixing plate 9 and the supporting plate 3 are in a vertical positional relationship. The two arc clamping plates 8, nuts 7, limiting slide grooves 5 and limiting sliders 6 are symmetrically arranged about the fixed threaded rod 12, so that the horizontal fixing assembly can cooperate with the vertical fixing assembly.

[0024] The detailed working process of this utility model is as follows:

[0025] When in use, first complete the fixation of the guide to be twisted, place the workpiece to be processed between the two arc clamping plates 8, and rotate the two-way threaded rod 4 by the knob. When the two-way threaded rod 4 rotates, the two nuts 7 will be threadedly engaged with the two-way threaded rod 4 under the restriction of the two limiting slide grooves 5 and the limiting slider 6, and then the two nuts 7 will move toward each other. When fixation is required, the two nuts 7 move closer to each other, driving the two arc clamping plates 8 to move closer to each other to complete the horizontal fixation of the guide. The operation is convenient and can quickly fix guides of different sizes and models, which is conducive to improving subsequent processing efficiency;

[0026] After completion, the fixed threaded rod 12 is rotated by turning the knob. When the fixed threaded rod 12 rotates, it will engage with the threaded through hole 11, and then move up and down, driving the arc pressure plate 13 to move up and down. When it needs to be fixed, the arc pressure plate 13 moves downward until it is tightened, completing the vertical fixation of the guide, and cooperating with the horizontal fixing component to improve the stability after fixation and the subsequent processing effect.

[0027] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model and are not limiting. Although the utility model is described in detail with reference to the preferred embodiments, ordinary technicians in this field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the purpose and scope of the technical solution of the utility model, which should be included in the scope of the claims of the utility model.
