Description

Technical Field

[0001] This utility model relates to the field of drilling machine equipment technology, and in particular to a multi-functional electrical discharge drilling machine. Background Technology

[0002] An electrical discharge drilling machine, also known as an electrical discharge punch or electrical discharge fine hole generator, works by using a continuously moving, hollow, thin metal tube (as an electrode) to perform pulsed spark discharge on the workpiece to remove metal and create holes. Electrical discharge drilling machines are generally used as auxiliary equipment for wire electrical discharge cutting machines, processing wire-threading holes, spinnerets, spinneret holes, filter plates, sieve plates, engine blades, cylinder cooling holes, and oil and air passages in hydraulic and pneumatic valve bodies. Unlike wire electrical discharge cutting machines and forming machines, its pulsed electrode is a hollow copper tube, with the medium passing through a fine hole in the center of the tube for cooling and chip removal.

[0003] Each existing EDM drilling machine can only process holes of the same specification and size. This requires companies to purchase multiple models of EDM drilling machines to meet the different workpiece requirements for drilling diameter, which increases the company's processing costs. In addition, each worker needs to manage multiple EDM drilling machines, which increases the labor intensity of the workers.

[0004] Therefore, there is a need to provide a multifunctional EDM drilling machine to solve the above problems. Utility Model Content

[0005] To overcome the above-mentioned shortcomings, the purpose of this utility model is to provide a multi-functional EDM drilling machine that is suitable for different workpieces with different hole diameter requirements, which can improve the processing efficiency of workpieces and reduce the processing cost of enterprises.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows: a multi-functional EDM drilling machine, including a machine base, a horizontal moving platform slidably mounted thereon, and a loading / unloading robot; multiple drilling machines and EDM machines capable of moving along a cross are vertically mounted on the machine base, and at least one set of product placement carriers are mounted on the horizontal moving platform, capable of driving the product placement carriers with workpieces mounted thereon to move toward or away from the drilling machines, and the loading / unloading robot is located on the side of the horizontal moving platform to move the workpieces with holes drilled on the product placement carriers to the unloading station.

[0007] Furthermore, multiple drilling machines and EDM machines are connected to a support frame vertically mounted on the machine base via a moving assembly. The moving assembly includes a sliding connecting frame and a displacement drive component that enables its horizontal movement. The back of the sliding connecting frame is slidably connected to a moving slide rail horizontally mounted on the support frame. The moving assembly provides driving force for the horizontal movement of the drilling machines and EDM machines, allowing drilling machines and EDM machines with different drilling diameters to move horizontally so that the workpiece can be matched with the corresponding drilling equipment.

[0008] Furthermore, it also includes a lifting drive component, with each of the drilling machines or EDM machines corresponding to one lifting drive component, and capable of moving up and down under the drive of the lifting drive component to perform drilling operations on the workpiece.

[0009] Furthermore, the bottom of the horizontal moving stage is connected to the machine surface via a second moving component. The second moving component includes a displacement drive and a second moving slide rail. The displacement drive drives the horizontal moving stage to move back and forth along the second moving slide rail. This adjusts the position of multiple workpieces on the horizontal moving stage relative to the drilling machine or EDM machine, moving each workpiece one by one below its corresponding drilling machine or EDM machine to ensure drilling accuracy.

[0010] Furthermore, the perforating machine includes a rotating head assembly and a wire guide assembly. The wire guide assembly includes a guide connecting plate located at the bottom of the lifting drive component. The guide connecting plate is provided with a guide component and a guide extension component from top to bottom along its height direction. Both the guide component and the guide extension component have interconnected guide holes.

[0011] The electrode wire is a slender component, which is prone to bending during the processing of the workpiece, affecting the processing quality and efficiency. A wire-supporting device is set at the bottom of the lifting drive component, corresponding to the position of the rotating head assembly of the drilling machine. This device will not affect the up and down movement of the rotating head assembly, but will also support and guide the electrode wire to stabilize it and ensure the processing effect of the hole on the workpiece.

[0012] Furthermore, the guide member is funnel-shaped, and the guide hole is coaxially arranged with the guide member. The funnel-shaped structure can guide the insertion of the electrode wire, making it easy for the electrode wire to pass through the guide member and the guide extension member in sequence. At this time, the guide member and the guide extension member can provide circumferential support for the electrode wire, and at the same time, it will not affect the drilling machine's drilling operation on the workpiece.

[0013] Furthermore, the product placement carrier includes a carrier support and a plurality of support tubes arranged vertically along its length. Each support tube has a support insertion hole extending through both ends along its axial direction in the middle. A locking groove communicating with the support insertion hole is opened perpendicularly to the axial direction on the support tube. The workpiece located inside the support tube can be pressed against the inner wall of the support tube by locking screws.

[0014] Furthermore, it also includes a loading platform with several workpiece slots along its height. The loading / unloading robot can vertically insert the processed workpieces into the corresponding workpiece slots. A protective cover is provided on the machine platform. The loading platform facilitates the loading / unloading robot to grasp the processed workpieces and arrange them neatly, eliminating the need for workers to collect them as a whole and effectively reducing the labor intensity of workers.

[0015] The beneficial effects of this utility model are:

[0016] In this invention, multiple drilling machines and EDM machines are integrated on the same machine platform, making the drilling equipment suitable for different workpieces with varying hole diameter requirements. This effectively improves workpiece processing efficiency and reduces processing costs for enterprises. Attached Figure Description

[0023] The preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings, so that the advantages and features of the present invention can be more easily understood by those skilled in the art, thereby making a clearer and more definite definition of the scope of protection of the present invention.

[0024] See appendix Figures 1 to 5 As shown, in the prior art, the hole punched by the drilling machine 3 on the workpiece 18 has a horizontal surface, while the hole punched by the EDM machine 4 on the workpiece has a curved surface. The corresponding processing machine is selected according to the different workpiece requirements for hole diameter and hole shape.

[0025] However, each EDM drilling machine 3 is equipped with only one drilling machine 3 or EDM machine 4. When processing workpieces, only one size of hole can be processed on the same machine. This requires enterprises to purchase different models and types of EDM drilling machines 3 to meet the processing needs of different workpieces, which leads to an increase in the enterprise's processing costs.

[0026] Therefore, this embodiment provides a multi-functional EDM drilling machine, including a machine base 1, a horizontal moving table 7 slidably mounted thereon, and a loading and unloading robot 16; the machine base 1 is vertically equipped with multiple drilling machines 3 and EDM machines 4 that can move along a cross, and multiple drilling machines 3 and EDM machines 4 with different drilling diameters are integrated on the equipment, so that a single machine can meet the drilling requirements of multiple workpieces with different drilling diameters and drilling shapes, thereby effectively reducing the processing and production costs of enterprises.

[0027] In some embodiments, see Appendix Figure 1 The drilling machine 3 and the EDM machine 4 are arranged vertically side by side on the sliding connecting frame 51. Specifically, there are 3 drilling machines 3 and 1 EDM machine 4. The hole diameters of the three drilling machines 3 are evenly distributed to adapt to the drilling hole diameter requirements of different workpieces. The cooperation between the EDM machine 4 and the drilling machine 3 can adapt to the requirements of different hole types.

[0028] The horizontal moving table 7 is equipped with at least one set of product placement carriers, which can drive the product placement carriers with workpieces installed to move toward or away from the drilling machine 3. The product placement carriers are used to place and position the workpieces that need to be drilled, so as to ensure that the workpieces will not be shifted in position during subsequent drilling, resulting in misalignment of the drilling.

[0029] The loading / unloading robot 16 is located on the side of the horizontal moving table 7 to move the workpieces with holes punched on the product placement carrier to the unloading station. The loading of workpieces into the product placement carrier to wait for drilling and the unloading of workpieces after drilling can both be completed automatically by the loading / unloading robot 16, which can effectively reduce the labor intensity of workers and improve the speed of loading / unloading workpieces compared with manual labor.

[0030] Multiple drilling machines 3 and EDM machines 4 are connected to a support frame 2 vertically mounted on a machine base 1 via a moving assembly 5. The moving assembly 5 includes a sliding connecting frame 51 and a displacement drive component that can drive its horizontal movement. The back of the sliding connecting frame 51 is slidably connected to a moving slide rail 52 horizontally mounted on the support frame 2. The moving assembly 5 provides driving force for the horizontal movement of the drilling machines 3 and EDM machines 4. Drilling machines 3 and EDM machines 4 with different drilling diameters move horizontally so that the workpiece can be matched with the corresponding drilling equipment.

[0031] Specifically, the displacement drive can be a drive cylinder or a drive module, and its drive end is connected to the sliding connecting frame 51. The moving slide rail 52 can provide guidance for the overall horizontal movement of the drilling machine 3 and the EDM machine 4, making them more stable during movement. The displacement drive can precisely adjust the position of the drilling machine 3 and the EDM machine 4.

[0032] It should be noted that the displacement drive component is not limited to a drive cylinder or drive module; it can also be other known mechanical structures that can drive the sliding connecting frame 51 to move back and forth. These will not be elaborated on here.

[0033] It also includes a lifting drive component 6, with each of the drilling machines 3 or EDM machines 4 corresponding to one lifting drive component 6, and capable of moving up and down under the drive of the lifting drive component 6, so as to perform drilling operations on the workpiece.

[0034] The bottom of the horizontal moving table 7 is connected to the surface of the machine base 1 via a second moving component 8. The second moving component 8 includes a displacement drive and a second moving slide rail 81. The displacement drive can drive the horizontal moving table 7 to move back and forth along the second moving slide rail 81. This adjusts the position of multiple workpieces located on the horizontal moving table 7 relative to the drilling machine 3 or EDM machine 4, moving each workpiece one by one below the corresponding drilling machine 3 or EDM machine 4 to ensure drilling accuracy.

[0035] The perforating machine 3 includes a rotating head assembly 31 and a wire guide assembly 32. The wire guide assembly 32 includes a guide connecting plate 321 located at the bottom of the lifting drive component 6. The guide connecting plate 321 is provided with a guide component 322 and a guide extension component 324 arranged sequentially from top to bottom along its height direction. Both the guide component 322 and the guide extension component 324 are provided with interconnected guide holes 323.

[0036] The electrode wire is a slender part, which is prone to bending during the processing of the workpiece, affecting the processing quality and efficiency. A wire-supporting device is set at the bottom of the lifting drive 6, which corresponds to the position of the rotating head assembly 31 of the drilling machine 3. This device will not affect the up and down movement of the rotating head assembly 31, but can also support and guide the electrode wire to stabilize it and ensure the processing effect of the hole on the workpiece.

[0037] The guide member 322 is funnel-shaped, and the guide hole 323 is coaxially arranged with the guide member 322. The funnel-shaped structure can guide the insertion of the electrode wire, making it easy for the electrode wire to pass through the guide member 322 and the guide extension member 324 in sequence. At this time, the guide member 322 and the guide extension member 324 can provide circumferential support for the electrode wire, and at the same time, it will not affect the drilling machine 3 from performing the drilling operation on the workpiece.

[0038] The product placement carrier includes a carrier support 10 and multiple support tubes 11 arranged vertically along its length. Each support tube 11 has a support insertion hole 12 extending through both ends along its axial direction in the middle. A locking groove 13 communicating with the support insertion hole 12 is formed perpendicularly to the axial direction of each support tube 11. The workpiece located inside the support tube 11 can be pressed against the inner wall of the support tube 11 by tightening the screws. The carrier support 10 provides support for the fixed arrangement of the multiple support tubes 11. A workpiece can be inserted into each support tube 11. By turning the screws in both directions, the workpiece can be pressed against the tube wall of the support tube 11, avoiding the phenomenon of the workpiece shifting and the hole size being reduced during subsequent drilling; or it can remove the workpiece from the tube wall of the support tube 11, making it easier to remove and unload the drilled workpiece.

[0039] In some embodiments, the horizontal moving table 7 is further provided with a flipping assembly 9, which includes a flipping motor 91 and a flipping support 92 supporting it. One end of the carrier support 10 in the length direction is fixedly connected to the drive end of the flipping motor 91. After one end of the workpiece is processed, the drive motor drives the carrier support 10 to rotate 180 degrees as a whole, so as to rotate the other end of the workpiece without drilling to a position below the drilling machine 3 or the EDM machine 4 for drilling, effectively improving the processing efficiency of the workpiece.

[0040] It also includes a loading platform 14, on which several workpiece slots 15 are formed along its height. The loading / unloading robot 16 can vertically insert the processed workpieces into the corresponding workpiece slots 15. A protective cover 17 is provided on the machine base 1. The loading platform 14 facilitates the loading / unloading robot 16 in picking up the processed workpieces and arranging them neatly, eliminating the need for workers to collect them as a whole, and effectively reducing the labor intensity of workers.

[0041] The above embodiments are only for illustrating the technical concept and features of this utility model. Their purpose is to enable those skilled in the art to understand the content of this utility model and implement it. They cannot be used to limit the protection scope of this utility model. All equivalent changes or modifications made in accordance with the spirit and essence of this utility model should be covered within the protection scope of this utility model.
