Detailed Implementation

[0019] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are some embodiments of this utility model, but not all embodiments.

[0020] Example 1:

[0021] An electrical discharge drilling device, such as Figure 1 and Figure 2As shown, the device includes a base plate 1, a sliding support mechanism, an electrode drive mechanism, and an electrode head 10. Both the sliding support mechanism and the electrode drive mechanism are mounted on the base plate 1. The electrode drive mechanism is located on one edge of the base plate 1, and the sliding support mechanism is located on one side of the motor drive mechanism. The electrode head 10 is mounted on the electrode drive mechanism, and the sliding support mechanism is located directly below the electrode head 10. The electrode drive mechanism drives the electrode head 10 to move up and down. The sliding support mechanism includes a support assembly and a sliding assembly. The sliding assembly is mounted on the support assembly and slidably connected to it. The workpiece to be drilled is mounted on the sliding assembly, and the electrode head 10 is positioned above the sliding assembly. The system includes two spaced-apart support blocks 2, each with a rectangular structure. The bottom of each support block 2 is welded to a base plate 1. Each support block 2 has a trapezoidal groove 21 at its top, and a sliding assembly is slidably connected to the groove 21. The sliding assembly includes two spaced-apart sliding plates 3, each positioned above one of the support blocks 2. The ends of the two sliding plates 3 are welded together via connecting plates 4 to improve the support effect on the workpiece. Each sliding plate 3 has a sliding strip at its bottom, protruding from the bottom. The sliding strip includes a sliding part 32 and a connecting part 31. The sliding part 32 is inserted into the groove 21 and connected to the groove. 21. Sliding fit: The connecting part 31 is located between the sliding part 32 and the sliding plate 3 and abuts against the surface of the support block 2. The width of the connecting part 31 is greater than the width of the top of the slide groove 21. The slide bar slides against the support block 2 through friction. Lubricating oil or grease can be applied appropriately in the slide groove 21 to reduce friction and facilitate the sliding adjustment of the sliding part 32. An adjustment hole 22 is provided on the outer side of the support block 2 located away from the electrode driving mechanism in the support assembly. The adjustment hole 22 has a strip-shaped structure and is connected to the slide groove 21. The width of the adjustment hole 22 is less than the height of the slide groove 21. Two threaded holes 321 are provided on the side of the sliding part 32 of the slide bar. 1. Bolts 23 are installed near both ends of the slide bar. After passing through the adjustment hole 22, the bolts 23 are connected to the threaded hole 321 to fix the sliding assembly on the support assembly. When it is necessary to move the sliding plate 3 to the left, the bolts 23 are unscrewed and the sliding plate 3 is pushed to slide. At this time, part of the sliding plate 3 will protrude from one end of the support block 2. The sliding plate 3 can be fixed on the support block 2 through the threaded hole 321 at the other end. The length of the bolt 23 is less than the depth of the threaded hole 321, so that after it is tightened, it can be limited by the outer side of the adjustment hole 22, thereby tightening and fixing the sliding plate 3 and the support block 2. The workpiece to be processed can be fixed on the sliding plate 3 by external calipers or other means to prevent it from shifting during processing.

[0022] Example 2:

[0023] This embodiment, based on the above embodiment, further defines the electrode driving mechanism. The electrode driving mechanism includes two support frames 5, a support beam 6, a lead screw 8, a reduction motor 7, and a connecting arm 9. The two support frames 5 are spaced apart, and the bottom of the support frame 5 is welded to the base plate 1. The support beam 6 is located on the top of the support frame 5 and is welded to the support frame 5. The support beam 6 has a through hole, and the lead screw 8 passes through the through hole of the support beam 6, extends between the two support frames 5, and is connected to the connecting arm 9. The reduction motor 7 is connected to the lead screw 8 at the top of the support beam 6, and the reduction motor 7 is used to drive the lead screw 8. The rotation of rod 8 causes the connecting arm 9 to move up and down. Limiting grooves are provided on the side of each support frame 5 near the lead screw 8. Slider 91s are provided on both sides of the support arm, and the sliders 91 slide in the limiting grooves to prevent the connecting arm 9 from rotating left and right when the lead screw 8 drives it, allowing it to move up and down perpendicular to the base plate 1. A threaded rod 11 is provided at the top of the electrode head 10, and the electrode head 10 is threadedly connected to the end of the support arm via the threaded rod 11. Electrode heads 10 of different lengths or diameters can be replaced according to the processing requirements of the workpiece. Other parts of this embodiment are the same as those in the above embodiment and will not be repeated here.

[0024] In the description of this utility model, it should be noted that the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", and "outer" used to indicate the orientation or positional relationship are based on the orientation or positional relationship shown in the accompanying drawings, or the orientation or positional relationship that the utility model product is usually placed in during use. They are only used to facilitate the description of this utility model and to simplify the description, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0025] Furthermore, the use of terms such as "horizontal" or "vertical" in the description of this utility model does not imply that the component is required to be absolutely horizontal or suspended, but rather that it can be slightly tilted. For example, "horizontal" simply means that its direction is more horizontal relative to "vertical," and does not mean that the structure must be completely horizontal, but can be slightly tilted.

[0026] In the description of this utility model, it should also be noted that, unless otherwise explicitly specified and limited, the terms "set," "install," "connect," and "link" should be interpreted broadly.
