Description

Technical Field

[0002] Electrical discharge machining (EDM) is a method of machining a workpiece in a certain medium by means of electrical erosion through pulsed discharge between the tool electrode and the workpiece electrode.

[0003] In related technologies, during the processing of control valves, micro electrical discharge machining (EDM) machines are often used to drill holes in workpieces such as valve plates and fuel injectors. The micro EDM machine includes a worktable, a machining head, and a fixture. A column is set on the top surface of the worktable, the machining head is connected to the column, and the fixture is set below the machining head for drilling holes in the workpiece.

[0004] Because the valve plate and the fuel injector are drilled in different ways, the valve plate remains stationary during the drilling process, while the fuel injector needs to rotate on the B-axis and C-axis. Therefore, different micro-electrical discharge machining (EDM) machines need to be selected according to different workpieces, which increases the cost of machining the control valve. As a result, there is a problem that the types of workpieces that can be processed by micro-electrical discharge machining machines are limited. Utility Model Content

Detailed Implementation

[0028] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, the accompanying drawings show only the parts relevant to the present invention, not the entire structure.

[0029] In the description of this utility model, unless otherwise explicitly specified and limited, the terms "connected," "linked," and "fixed" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0030] In this invention, unless otherwise explicitly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0031] In the description of this embodiment, the terms "upper," "lower," "right," etc., refer to the orientation or positional relationship shown in the accompanying drawings. They are used only for ease of description and simplification of operation, and do not 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. In addition, the terms "first" and "second" are only used for distinction in description and have no special meaning.

[0032] See Figure 1 and Figure 2 This utility model provides a dual-station micro-electrical discharge machining (EDM) system, including a support assembly 1, two sets of Z-axis motion mechanisms 2, a first machining head 3, a second machining head 4, a first machining device 5, and a second machining device 6. The support assembly 1 includes a worktable 11 and a column 12, with the column 12 positioned on the top surface of the worktable 11. The two sets of Z-axis motion mechanisms 2 are respectively positioned on both sides of the column 12. The first machining head 3 and the second machining head 4 are respectively connected to the two sets of Z-axis motion mechanisms 2, enabling the first machining head 3 and the second machining head 4 to move along the Z-axis (e.g., ...). Figure 1 The first processing head 3 is connected to an X-axis motion mechanism and a Y-axis motion mechanism, enabling the first processing head 3 to move along the X-axis (as shown in the diagram). Figure 1 (as shown in the X axis) and Y axis (as shown in the Y axis) Figure 2 The first processing device 5 includes a first clamp 51 and a rotary swing mechanism. The first clamp 51 is located below the first processing head 3, and the rotary swing mechanism is connected to the first clamp 51. The second processing device 6 includes a second clamp 61 and an XY-axis moving assembly 63. The second clamp 61 is located below the second processing head 4, and the XY-axis moving assembly 63 is connected to the second clamp 61, enabling the second clamp 61 to move along the X-axis and Y-axis.

[0033] In this embodiment, the X-axis is parallel to the length direction of the worktable 11, the Y-axis is parallel to the width direction of the worktable 11, and the Z-axis is parallel to the height direction of the column 12. The first processing device 5 and the second processing device 6 are spaced apart along the X-axis on the top surface of the worktable 11. The X-axis motion mechanism includes an X-axis drive 31, and the Y-axis motion mechanism includes a Y-axis drive 32. Both the X-axis drive 31 and the Y-axis drive 32 are motors. The fixed end of the Y-axis drive 32 is fixedly connected to the column 12, and the output end of the Y-axis drive 32 is connected to a lead screw (not shown in the figure). The fixed end of the X-axis drive 31 is fixedly connected to a slider threaded on the lead screw. The X-axis drive 31 is connected to a lead screw (not shown in the figure), and the first processing head 3 is fixedly connected to the slider threaded on the lead screw, so that the first processing head 3 can slide along the X-axis and Y-axis directions.

[0034] Thus, the fuel injector is mounted on the first fixture 51 and the valve plate is mounted on the second fixture 61. The Z-axis motion mechanism 2 can drive the first machining head 3 and the second machining head 4 to move along the Z-axis, thereby adjusting the distance between the first machining head 3 and the second machining head 4 and the worktable 11. The X-axis motion mechanism and the Y-axis motion mechanism can drive the first machining head 3 to move along the X-axis and Y-axis. The XY-axis moving component 63 can drive the second fixture 61 to move along the X-axis and Y-axis, so that the first machining head 3 and the second machining head 4 are respectively positioned above the fuel injector and the valve plate. Manual adjustment can save energy and reduce costs, and quickly position the second fixture 61, achieving the effect of simultaneously machining the fuel injector and the valve plate on the worktable 11. This increases the types of workpieces that the micro EDM machine tool can process and improves processing efficiency.

[0035] It should be noted that the X-axis drive unit 31 and the Y-axis drive unit 32 can also be other linear drive structures, such as cylinders or linear motors. The specific structure of the X-axis drive unit 31 and the Y-axis drive unit 32 can be adjusted according to actual needs, and will not be listed in detail here.

[0036] See Figure 1 and Figure 3 In some embodiments, the second processing device 6 includes a processing base 62, which is fixedly mounted on the worktable 11, and an XY axis moving component 63 is disposed between the second clamp 61 and the processing base 62.

[0037] It is understood that the processing base 62 can be fixedly mounted on the worktable 11 by welding or other means, or it can be detachably mounted on the worktable 11 by bolts. In this embodiment, the processing base 62 is connected to the worktable 11 by bolts.

[0038] Thus, the machining base 62 can provide stable support for the XY axis moving assembly 63, enabling the second fixture 61 to move along the X and Y axes under the action of the XY axis moving assembly 63, thereby adjusting the relative position of the valve plate and the second machining head 4 and improving the stability of the micro-electric spark drilling of the valve plate.

[0039] It should be noted that the connection method between the worktable 11 and the processing base 62 can be adjusted according to actual needs, and will not be listed in detail here.

[0040] See Figure 1 and Figure 3 In some embodiments, the XY-axis moving assembly 63 includes an X-axis slide 631 and a Y-axis slide 632. The X-axis slide 631 is slidably connected to the machining base 62 along the X-axis, and the Y-axis slide 632 is slidably connected to the X-axis slide 631 along the Y-axis. The second clamp 61 moves synchronously with the Y-axis slide 632. The X-axis slide 631 is located between the Y-axis slide 632 and the machining base 62.

[0041] Thus, by moving the X-axis slide 631 and the Y-axis slide 632, the second clamp 61 can be moved synchronously, thereby quickly positioning the valve plate held by the second clamp 61 and improving processing efficiency.

[0042] Furthermore, both the X-axis slide 631 and the Y-axis slide 632 are fitted with protective shells 633 to prevent wastewater and residue from contacting the X-axis slide 631 and the Y-axis slide 632.

[0043] See Figure 1 , Figure 3 and Figure 4 In some embodiments, the XY axis moving assembly 63 includes two dial indicators 636, which are respectively connected to the X-axis slide 631 and the Y-axis slide 632 for measuring the moving distance of the X-axis slide 631 and the Y-axis slide 632.

[0044] In this embodiment, the dial indicator 636 is connected to a reading base 6361 and a fixed base 6362. There are two corresponding reading bases 6361, and the two dial indicator 636 bases are fixedly connected to the X-axis slide 631 and the Y-axis slide 632 respectively. The measuring end of the dial indicator 636 abuts against the reading base 6361. There are two corresponding fixed bases 6362, and the two fixed bases 6362 of the dial indicator 636 are fixedly connected to the machining base 62 and the X-axis slide 631 respectively, for fixing the position of the dial indicator 636.

[0045] Thus, the dial indicator 636 can measure the moving distance of the X-axis slide 631 and the Y-axis slide 632, which makes it easier for the operator to adjust the position of the second clamp 61, thereby adjusting the valve plate held by the second clamp 61 to a suitable position and improving positioning efficiency.

[0046] See Figure 1 and Figure 3 In some embodiments, a water receiving platform 64 is provided on the top surface of the Y-axis slide 632, and a second clamp 61 is disposed inside the water receiving platform 64. The water receiving platform 64 is connected to a drain pipe 641. In this embodiment, the projections of the X-axis slide 631 and the Y-axis slide 632 on the worktable 11 are both located within the projection of the water receiving platform 64 on the worktable 11.

[0047] In this way, when the valve plate surface is drilled by micro-electro-electric spark, the wastewater and residue generated can fall into the water receiving platform 64 and be discharged to the outside through the drain pipe 641, avoiding contact with the X-axis slide 631 and Y-axis slide 632, thus affecting the sliding of the second clamp 61 on the X-axis and Y-axis.

[0048] See Figure 3 and Figure 4 In some embodiments, the X-axis slide 631 is slidably connected to a first slide rail 6311, which is fixedly connected to the processing base 62. The Y-axis slide 632 is slidably connected to a second slide rail 6321, which is fixedly connected to the X-axis slide 631. The XY-axis moving assembly 63 also includes two limiting members 637. The two limiting members 637 are respectively connected to the first slide rail 6311 and the second slide rail 6321 to limit the position of the X-axis slide 631 and the Y-axis slide 632.

[0049] In this embodiment, two first slide rails 6311 and two second slide rails 6321 are provided. The length direction of the first slide rail 6311 is parallel to the X-axis, and the length direction of the second slide rail 6321 is parallel to the Y-axis. The bottom surfaces of the X-axis slide 631 and the Y-axis slide 632 are respectively fixedly connected to sliders (not shown in the figure) adapted to the first slide rail 6311 and the second slide rail 6321, so that the X-axis slide 631 slides on the first slide rail 6311 and the Y-axis slide 632 slides on the second slide rail. The limiting member 637 is a track limiter, and two limiting members 637 are provided. The two limiting members 637 are respectively connected to one of the first slide rails 6311 and one of the second slide rails 6321.

[0050] Thus, the limiting component 637 can restrict the movement of the X-axis slide 631 and the Y-axis slide 632, so that when the valve plate moves to the machining position, the X-axis slide 631 and the Y-axis slide 632 can be prevented from shifting during operation, thereby affecting the machining effect.

[0051] It should be noted that the types of limit components 637 can be adjusted according to actual needs, and will not be listed in detail here.

[0052] See Figure 1 and Figure 4In some embodiments, the XY axis moving assembly 63 includes two micrometers 634, one micrometer 634 is connected to a connecting block 6341, the two connecting blocks 6341 are fixedly connected to the bottom surface of the X-axis slide 631 and the bottom surface of the Y-axis slide 632 respectively, and the moving end of the micrometer 634 abuts against the connecting block 6341.

[0053] In this embodiment, the micrometer 634 is also connected to a connecting base 6342. The two connecting bases 6342 are fixedly connected to the processing base 62 and the X-axis slide 631 respectively. The fixed end of the micrometer 634 passes through the connecting base 6342 and is fixedly connected to the connecting base 6342.

[0054] Thus, turning the micrometer 634 causes its moving end to extend and push the connecting block 6341 to slide, which in turn allows the connecting block 6341 to drive the X-axis slide 631 or the Y-axis slide 632 to slide. At the same time, by reading the micrometer 634, the moving distance of the X-axis slide 631 or the Y-axis slide 632 can be read, making it convenient for the operator to adjust the position of the X-axis slide 631 and the Y-axis slide 632, thereby quickly positioning the valve plate.

[0055] See Figure 5 In some embodiments, the XY axis moving assembly 63 further includes a spring 635. Two springs 635 are provided corresponding to the connecting block 6341. One end of the spring 635 abuts against the connecting block 6341, and the other end is fixedly connected to a fixing plate 6351. The two fixing plates 6351 are respectively fixedly mounted on the X-axis slide 631 and the Y-axis slide 632.

[0056] Thus, when the micrometer 634 extends forward and pushes the connecting block 6341 to move, the spring 635 is compressed; when the micrometer 634 retracts backward, the spring 635 releases its elastic force, pushing the connecting block 6341 to always be in contact with the micrometer 634, making it convenient for the operator to control the movement of the X-axis slide 631 and the Y-axis slide 632.

[0057] See Figure 1 and Figure 6 In some embodiments, each Z-axis motion mechanism 2 includes a positioning drive 21 and a machining drive 22. The two positioning drive 21 are connected to the column 12, and the two machining drive 22 are connected to the first machining head 3 and the second machining head 4, respectively.

[0058] In this embodiment, the positioning drive 21 is a motor, with its output end facing the worktable 11. The fixed end of the positioning drive 21 is fixedly connected to the column 12, and a lead screw (not shown in the figure) is connected to the positioning drive 21. The fixed end of the machining drive 22 is fixedly connected to the slider on the lead screw. The machining drive 22 is also a motor, connected to a lead screw, and the first machining head 3 and the second machining head 4 are respectively fixedly connected to the slider on the lead screw. The support assembly 1 also includes a connecting plate 13, one end of which is fixedly connected to the side wall of the fixed end of the positioning drive 21, and the other end of which is fixedly connected to the side wall of the fixed end of the positioning drive 21.

[0059] Thus, the positioning drive 21 can drive the machining drive 22 to move along the Z-axis. The distance between the machining drive 22 and the worktable 11 is adjusted according to the type and specifications of the workpiece being processed. The machining drive 22 can drive the first machining head 3 or the second machining head 4 to move and drill holes in the workpiece.

[0060] It should be noted that the positioning drive component 21 and the machining drive component 22 can also be other linear drive components, such as lead screws, linear motors, etc. The specific structure of the positioning drive component 21 and the machining drive component 22 can be adjusted according to actual needs, and will not be listed in detail here.

[0061] See Figure 1 In some embodiments, the rotary swing mechanism (not shown in the figure) includes a B-axis swing mechanism (not shown in the figure) and a C-axis rotation mechanism (not shown in the figure), both of which are connected to the first clamp 51.

[0062] In this embodiment, the first clamp 51 is connected to the frame 52, the frame 52 is set on the worktable 11, the B-axis swing mechanism includes a B-axis drive 53, which is a motor, and the fixed end of the B-axis drive 53 is fixedly connected to the frame 52. The C-axis rotation mechanism includes a C-axis drive, which is a motor, the C-axis drive is located inside the frame 52, and the output end of the C-axis drive is fixedly connected to the second clamp 61.

[0063] Thus, by having the second clamp 61 drive the fuel injector to swing on the B-axis and rotate on the C-axis, it is convenient to perform micro-electrical discharge drilling on the fuel injector.

[0064] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present utility model, and are not intended to limit the implementation of the present utility model. Those skilled in the art can make various obvious changes, readjustments, and substitutions without departing from the protection scope of this utility model. It is neither necessary nor possible to exhaustively describe all embodiments here.
