Description

Technical Field

[0001] The utility model relates to the technical field of spark machine electrode guides, in particular to an electrode guide device for precision electric spark machine processing. Background Art

[0002] The spark machine electrode guide device refers to a device used to guide the relative position between the electrode and the workpiece during the spark machine processing. Its main function is to ensure that the gap between the electrode and the workpiece is uniform and the discharge position is accurate, thereby improving processing accuracy and efficiency.

[0003] As disclosed in the authorization announcement number CN219881493U, an electrode guide device for precision electrospark machining is disclosed, which belongs to the technical field of mechanical processing equipment. The device includes a mounting assembly and a guide mechanism, and the guide mechanism is slidably connected to the mounting assembly. The guide mechanism includes an adjusting device and a fixing device, and the fixing device is rotatably connected to one side of the adjusting device. When in use, the electrode is fixed between the semi-arc plate and the extension block. When in use, by loosening the first adjusting bolt, the vertical plate and the extension block can slide inside the through groove and the slide groove. After adjusting the position, tightening the first adjusting bolt can fix the adjusting device on the mounting plate. When inclined drilling is required, rotating a second adjusting bolt can make the extension block on one side move outward, so that the rotating shafts on both sides rotate and make the extension blocks on both sides tilted, thereby enabling inclined drilling. When the placement block moves outward, the sliding rods on both sides can increase the stability of the equipment.

[0004] However, the electrode guide device mentioned in the patent has a relatively simple overall guide adjustment and cannot be adjusted in a diversified manner, so that the guide accuracy cannot reach the best. At the same time, the existing guide device has a complex guide structure, and the maintenance time is long and the cost is high when it is damaged. Utility Model Content
