Description

Technical Field

[0001] This utility model relates to the field of electrical discharge drilling machine technology, specifically to an electrical discharge drilling machine that can suction debris under negative pressure. Background Technology

[0002] In the field of electrical discharge machining, debris is usually generated during the machining process. This debris is often mixed with the sprayed cutting fluid. If it is not removed in time, it will have an adverse effect on machining quality, efficiency and equipment operation.

[0003] In the current EDM drilling process, the method of cleaning debris from the cutting fluid is usually natural sedimentation. This method is inefficient and makes it difficult to remove debris quickly and thoroughly. On the one hand, debris that is not removed in time is prone to accumulate in the processing area, which affects the processing. On the other hand, it is difficult to remove debris from the cutting fluid, which affects the secondary use of the cutting fluid, resulting in waste of cutting fluid and increased processing costs. Utility Model Content

[0004] In view of the problems existing in the current EDM drilling machine, this utility model is proposed.

[0005] Therefore, the purpose of this utility model is to provide an EDM drilling machine that can suction debris under negative pressure, which solves the problem that existing EDM drilling machines usually use natural sedimentation to clean debris from the cutting fluid during the processing, which is inefficient and makes it difficult to remove debris quickly and thoroughly.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] An EDM drilling machine capable of negative pressure suction of debris includes a drilling machine worktable. A workpiece placement platform is fixedly connected to the upper surface of the drilling machine worktable. A drilling machine body is fixedly connected to the upper surface of the drilling machine worktable. An annular groove is formed around the outer surface of the workpiece placement platform on the drilling machine worktable. A liquid outlet pipe is formed between the lower surface of the workpiece placement platform and the annular groove and the liquid outlet pipe. A guide groove is formed between the annular groove and the liquid outlet pipe. A fixing block is provided on the lower surface of the liquid outlet pipe. A sliding groove is formed on one side of the fixing block. A collection filter frame is slidably arranged inside the sliding groove. A fixing mechanism is provided at one end of the collection filter frame. The collection filter frame is fixedly connected to the inside of the sliding groove through the fixing mechanism. Mounting holes are fixedly connected to both the upper and lower ends of the sliding groove. The lower end of the liquid outlet pipe is fixedly connected to the inside of the upper mounting hole. A conical frame is fixedly connected to the inside of the lower mounting hole. A negative pressure water pump is fixedly connected to the lower surface of the drilling machine worktable. A first connecting pipe is fixedly connected between the negative pressure water pump and the conical frame.

[0008] Preferably, the fixing mechanism includes two fixing frames, two lead screws, two insert blocks, two knobs, a pressure plate, and insert strips. The fixing frames are fixedly connected to the upper surface of the fixing blocks. The two lead screws are rotatably connected to the interior of their respective fixing frames. The two insert blocks are threaded onto the walls of the lead screws. The upper ends of the two lead screws penetrate the upper surface of the interior of their respective fixing frames and are fixedly connected to their respective knobs. The pressure plate is fixedly connected to one end of the collection filter frame. Two slots are symmetrically opened on one side of the fixing block. The two insert strips are slidably disposed inside their respective slots and symmetrically fixedly connected to one side of the pressure plate.

[0009] Preferably, the inner walls of the two fixed frames are symmetrically provided with two limiting grooves, and each limiting groove is slidably provided with a limiting block inside, and each limiting block is symmetrically fixedly connected to one side of the corresponding insertion block.

[0010] Preferably, the pressure plate and the fixing block are provided with annular sealing gaskets.

[0011] Preferably, each of the two inserts has a fixing groove on one side, and the two fixing grooves are respectively connected to the interior of the corresponding slot.

[0012] Preferably, one end of the negative pressure water pump is fixedly connected to a second connecting pipe.

[0013] The technical effects and advantages provided by this utility model in the above technical solution are as follows:

[0014] 1. This utility model utilizes a negative pressure water pump to create a negative pressure environment within the outlet pipe, rapidly drawing in a mixture of cutting fluid and debris. The mixture is collected in an annular trough and then flows into the outlet pipe through a guide channel. A collection filter frame intercepts debris, while the cutting fluid is discharged through a conical frame and recovered via a second connecting pipe. This achieves highly efficient separation of debris and cutting fluid, significantly improving cleaning efficiency compared to traditional natural sedimentation methods. It prevents debris accumulation from affecting machining quality and simultaneously enables the recycling of cutting fluid, reducing processing costs.

[0015] 2. This utility model allows for quick locking or disassembly of the collection filter frame via a screw, lead screw, and insert block. The limiting block and limiting groove ensure linear movement of the insert block, preventing offset; the annular sealing gasket enhances the seal between the pressure plate and the fixing block, preventing cutting fluid leakage. When debris needs to be removed, simply rotate the knob to remove the collection filter frame. This simple operation reduces downtime for maintenance and improves the practicality and ease of use of the equipment. Attached Figure Description

[0022] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0023] This utility model discloses an electrical discharge drilling machine that can suction debris under negative pressure.

[0024] Reference Figure 1-3An EDM drilling machine capable of negative pressure suction of debris includes a drilling machine workbench 1, a workpiece placement platform 2 fixedly connected to the upper surface of the drilling machine workbench 1, a drilling machine body 3 fixedly connected to the upper surface of the drilling machine workbench 1, an annular groove surrounding the outer surface of the workpiece placement platform 2, a liquid outlet pipe 4 between the lower surface of the workpiece placement platform 2, a guide groove between the annular groove and the liquid outlet pipe 4, a fixing block 5 on the lower surface of the liquid outlet pipe 4, a sliding groove on one side of the fixing block 5, a collection filter frame 6 slidably arranged inside the sliding groove, a fixing mechanism at one end of the collection filter frame 6, the collection filter frame 6 being fixedly connected to the inside of the sliding groove by the fixing mechanism, mounting holes fixedly connected to both the upper and lower ends of the sliding groove, the lower end of the liquid outlet pipe 4 being fixedly connected to the inside of the upper mounting hole, a conical frame 7 being fixedly connected to the inside of the lower mounting hole, a negative pressure water pump 8 fixedly connected to the lower surface of the drilling machine workbench 1, and a first connecting pipe 9 fixedly connected between the negative pressure water pump 8 and the conical frame 7.

[0025] The negative pressure water pump 8 is connected to the conical frame 7 through the first connecting pipe 9. After starting, it forms a negative pressure environment in the outlet pipe 4. The cutting fluid and debris mixture generated during the processing is collected by the annular groove around the workpiece placement platform 2 and flows into the outlet pipe 4 through the guide groove. Under the action of negative pressure, it flows downward quickly. Then the debris passes through the inside of the collection filter frame 6, while the cutting fluid is discharged from the conical frame 7.

[0026] To facilitate the disassembly of the collection filter frame 6, such as Figure 1-3 As shown, the fixing mechanism includes two fixing frames 10, two lead screws 11, two insert blocks 12, two knobs 13, a pressure plate 14, and insert strips 15. The fixing frames 10 are fixedly connected to the upper surface of the fixing block 5. The two lead screws 11 are rotatably connected to the interior of the corresponding fixing frames 10. The two insert blocks 12 are threaded onto the rod wall of the lead screws 11. The upper ends of the two lead screws 11 pass through the upper surface of the interior of the corresponding fixing frames 10 and are fixedly connected to the corresponding knobs 13. The pressure plate 14 is fixedly connected to one end of the collection filter frame 6. Two slots are symmetrically opened on one side of the fixing block 5. The two insert strips 15 are slidably set in the interior of the corresponding slots and are symmetrically fixedly connected to one side of the pressure plate 14. A fixing groove is opened on one side of each of the two insert strips 15, and the two fixing grooves are respectively connected to the interior of the corresponding slots.

[0027] Rotating the knob 13 drives the lead screw 11 to rotate, and the threaded insert 12 moves along the limiting groove on the inner wall of the fixed frame 10. Then each insert 12 slides out from the inside of the corresponding fixed groove, so that the collection filter frame 6 can be pulled out for easy cleaning. After cleaning, insert the two inserts 15 into the inside of the corresponding slots, and then rotate the knob 13 in the opposite direction to fix the collection filter frame 6.

[0028] To ensure stable movement of the insert block 12, such as Figure 1-2As shown, two limiting grooves are symmetrically opened on the inner walls of the two fixed frames 10. Each limiting groove has a limiting block 16 slidably arranged inside it. Each limiting block 16 is symmetrically fixedly connected to one side of the corresponding insert block 12.

[0029] The limiting block 16, in conjunction with the limiting groove, ensures that the insert block 12 moves linearly.

[0030] To prevent coolant leakage, such as Figure 1-2 As shown, the pressure plate 14 and the fixing block 5 are provided with annular sealing gaskets 17.

[0031] When the collection filter frame 6 is fixed, the pressure plate 14 can squeeze the annular sealing gasket 17, thereby increasing the sealing of the device to prevent cutting fluid leakage.

[0032] To facilitate the collection of cutting fluid, such as Figure 1-2 As shown, a second connecting pipe 18 is fixedly connected to one end of the negative pressure water pump 8.

[0033] The second connecting pipe 18 allows for easy recovery of the cutting fluid to the cutting fluid storage device, enabling the cutting fluid to be recycled.

[0034] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
