Description

TECHNICAL FIELD

[0001] The utility model relates to electric spark processing machine tool technical field, concretely is electric spark processing machine tool. BACKGROUND

[0002] Electric spark processing machine tool mainly produces the repeated electric pulse on tool electrode and metal workpiece, produces the electric spark of discharge and carries out the electric erosion to metal workpiece surface to process metal workpiece, it utilizes the local, instantaneous high temperature of pulse discharge to etch the metal material. Pulse voltage is applied between tool electrode and workpiece electrode, when the gap between two poles reaches certain small distance, pulse discharge will occur. The current density in discharge channel is extremely high, and a large amount of heat energy is released instantaneously, so that the metal material in the local area of electrode is rapidly melted, vaporized and etched. This processing method avoids the problems of workpiece deformation and tool wear caused by cutting force in traditional mechanical processing.

[0003] But the existing electric spark processing machine tool is directly placed to workpiece on the workbench and processed, leading to the workpiece displacement during processing, thereby causing the workpiece damage, and the workpiece will produce waste after processing, which falls on the workbench and needs to be cleaned manually, which is inconvenient, therefore, we provide electric spark processing machine tool.

[0020] The specific embodiments of this utility model will be further described below with reference to the accompanying drawings. It should be noted that these descriptions are for the purpose of aiding understanding of this utility model, but do not constitute a limitation thereof. Furthermore, the technical features involved in the various embodiments of this utility model described below can be combined with each other as long as they do not conflict with each other. Example 1

[0021] Please see Figures 1-5This utility model provides a technical solution: an electrical discharge machining (EDM) machine tool, including a support base 1, with a mounting base 2 and a mounting box 7 fixed to the upper end of the support base 1 respectively. A first sliding seat 3 is provided at the upper end of the mounting base 2, a second sliding seat 4 is provided at the upper end of the first sliding seat 3, a third sliding seat 5 is provided on one side of the second sliding seat 4, and an EDM head 6 is mounted at the lower end of the third sliding seat 5. A control box 8 is provided at one end of the mounting box 7, and a protective box 9 is installed inside the mounting box 7. A worktable 10 is fixed inside the protective box 9, and a rotating groove 11 is opened on one side of the protective box 9. A bidirectional screw 12 is rotatably mounted inside the rotating groove 11. A stepper motor 14 is fixed to one end of the protective box 9, and a stepper motor 14 is mounted on one side of the stepper motor 14. The gear 13 is installed, and the two sides of the bidirectional screw 12 are respectively provided with a first clamping plate 15 and a second clamping plate 16. A sliding column 17 is fixed inside one side of the protective box 9. Limiting plates 18 are fixed at both ends of the first clamping plate 15 and the second clamping plate 16. A drive motor 27 is fixed at the bottom inside the mounting box 7. A drive wheel 28 is installed on one side of the drive motor 27. A first driven wheel 29 and a second driven wheel 30 are respectively provided on both sides of one end of the mounting base 2. A third driven wheel 31 and a fourth driven wheel 32 are respectively provided on one side of the bottom inside the mounting box 7. A second transmission belt 34 is provided on the side wall of the first driven wheel 29 and the second driven wheel 30. A first transmission belt 33 is provided on the side wall of the drive wheel 28.

[0022] The bidirectional screw 12 passes through the first clamping plate 15 and the second clamping plate 16, and the bidirectional screw 12 is meshed with the gear 13.

[0023] The sliding column 17 passes through the first clamping plate 15 and the second clamping plate 16, and the sliding column 17 is slidably connected to both the first clamping plate 15 and the second clamping plate 16.

[0024] The first clamping plate 15 and the second clamping plate 16 are both located inside the protective box 9, and the first clamping plate 15 and the second clamping plate 16 are slidably connected to the protective box 9.

[0025] Specifically, the workpiece to be processed is placed in the middle position on the worktable 10, and then the stepper motor 14 is started to rotate forward via the control box 8. The stepper motor 14 then drives the gear 13 to rotate, which in turn drives the bidirectional screw 12 meshing with it to rotate. The bidirectional screw 12 rotates through the rotating groove 11 on the protective box 9. The bidirectional screw 12 then drives the first clamping plate 15 and the second clamping plate 16 on both sides to move closer together, and the first clamping plate 15 and the second clamping plate 16 slide on the sliding column 17. When the first clamping plate 15 and the second clamping plate 16 clamp the two sides of the workpiece, they stop, thus completing the fixation. Conversely, when the first clamping plate 15 and the second clamping plate 16 move away from each other, the first clamping plate 15 and the second clamping plate 16 will dispose of the waste material that falls onto the worktable 10. The workpiece is pushed into the mounting box 7 through the gap between the worktables 10. After the first clamping plate 15 and the second clamping plate 16 clamp the workpiece, the drive motor 27 is started by the control box 8 to drive the drive wheel 28 to rotate forward. At this time, the drive wheel 28 will drive the third driven wheel 31 and the fourth driven wheel 32 to rotate through the first transmission belt 33. Then, the drive wheel 28 and the third driven wheel 31 will drive the protective box 9 to rise through the second transmission belt 34, so that the workpiece in the worktable 10 is close to the EDM head for easy processing. After the workpiece is processed, the drive motor 27 is started by the control box 8 to drive the drive wheel 28 to rotate in reverse, so that the protective box 9 drives the worktable 10 and the workpiece to descend. Then the workpiece can be removed. This allows the EDM machine tool to quickly clamp the workpiece, prevent the workpiece from shifting, and clean up the waste on the worktable 10. Example 2

[0026] Please see Figures 1-5 This utility model provides a technical solution: an electrical discharge machining tool, a collection box 20 is slidably mounted on the other end of the mounting box 7 near the center, and clamping plates 19 are fixed on both sides of the other end of the mounting box 7. A filter box 21 is slidably mounted inside the collection box 20. A fixing box 22 is fixed to one end of the collection box 20. Slide plates 23 are mounted on both sides inside the fixing box 22. A first push plate 25 is fixed to one end of one slide plate 23, and a second push plate 26 is fixed to one end of the other slide plate 23. A spring 24 is provided on one side of the slide plate 23.

[0027] The slide plate 23 is slidably connected to the fixed box 22, and one end of the slide plate 23 passes through the fixed box 22 and is slidably connected to the card plate 19;

[0028] The fixed box 22 is slidably connected to the first push plate 25 and the second push plate 26, and the spring 24 is located inside the fixed box 22.

[0029] Specifically, by simultaneously pulling the first push plate 25 and the second push plate 26, the first push plate 25 and the second push plate 26 cause the sliding plate 23 inside the fixed box 22 to move closer to each other. At this time, the sliding plate 23 will compress the spring 24. When the collection box 20 is completely inserted into the installation box 7, the process stops. Then, the first push plate 25 and the second push plate 26 are released, allowing the sliding plate 23 to slide into the clamping plate 19 under the elasticity of the spring 24, thus completing the installation. Disassembly is similar. When the residual waste material after the surface processing of the workbench 10 is discharged into the installation box 7 by the used working fluid, the waste material and working fluid will fall into the filter box 21. At this time, the filter box 21 will block the waste in the working fluid, so that the waste remains in the filter box 21. Then the working fluid will continue to fall to the bottom of the collection box 20, so that the used working fluid and waste are separated. After the collection box 20 is pulled out from the installation box 7, the filter box 21 can be pulled to remove the filter box 21 from the collection box 20. This allows the waste in the filter box 21 and the working fluid in the collection box 20 to be processed. The EDM machine tool can quickly load and unload the collection box 20 and separate the used working fluid and waste, which is convenient for waste recycling.
