Abstract
Description
Technical Field
[0001] The present disclosure relates to the technical field of electric spark machining equipment, and in particular to an electrode clamping fixture and an electric spark machine tool. Background Art
[0002] Sinking EDM (Electro-Discharge Machining) is a method of machining a workpiece through the electro-erosion effect of pulsed discharges between the tool electrode and the workpiece electrode in a specific medium. EDM is widely used in perforation and cavity machining, especially for machining densely distributed features with high positional accuracy and dimensional precision, which cannot be processed using conventional processes. Therefore, sinking EDM technology is required.
[0003] During EDM (Electrodischarge Machining), the relative position and angle between the electrode and the workpiece or mold often need to be changed to meet machining requirements. Currently, a sinusoidal magnetic table is often used to assist in changing the angle of the workpiece or mold. The angled workpiece or mold is fixed by the sinusoidal magnetic table, and then the workpiece or mold is machined using a vertical electrode on the machine tool. However, this method is relatively complex to operate, and the sinusoidal magnetic table has limited adjustment angles for the workpiece or mold, resulting in poor operability, reduced workpiece yield, and redundant device structure, increasing manufacturing costs.

It will be understood that if the illustrated device were flipped upside down, the component described as "upper" would become the component "lower." When a structure is referred to as "on" another structure, this may mean that the structure is integrally formed with the other structure, that the structure is "directly" disposed on the other structure, or that the structure is "indirectly" disposed on the other structure via the other structure.
[0035] The terms "a", "an", "the", "said" and "at least one" are used to indicate the presence of one or more elements / components / etc.; the terms "including" and "having" are used to express open-ended inclusion and mean that additional elements / components / etc. may be present in addition to the listed elements / components / etc.; the terms "first", "second" and "third" etc. are used only as labels and are not intended to limit the quantity of their objects.
[0036] In related technologies, EDM can be used in a variety of processing scenarios. Take EDM processing of submerged gate position as an example. Since the submerged gate may have a variety of angles and positions, the workpiece needs to be adjusted to the position of the corresponding electrode before processing.
[0037] Currently, the common method for adjusting the relative position of the electrode and workpiece is to use a sinusoidal magnetic table. First, the sinusoidal magnetic table is adjusted to the desired gate angle, and then the workpiece is fixed on the sinusoidal magnetic table for sub-gate processing. This process is cumbersome, and the angle of the sinusoidal magnetic table must be adjusted each time to adapt to the relative position of the workpiece and electrode. The sinusoidal magnetic table's angle adjustment is limited, making it impossible to achieve multiple angle adjustments. This can easily lead to angular errors, resulting in a decrease in yield. Furthermore, this device is relatively complex in structure, has poor reusability, and is inconvenient to install and manufacture.
[0038] Based on this, the embodiment of the present disclosure provides an electrode clamping fixture for clamping electrodes, such as Figure 1 As shown, the fixture includes: a clamping base 100 , a connecting member 200 , a first rotating shaft 300 , a first fastener 410 and a second rotating shaft 500 .
[0039] Among them, a first groove 101 is opened at one end of the clamping base 100; the connecting member 200 is a cylindrical structure, the connecting member 200 is passed through the clamping base 100, and the connecting member 200 is arranged on the side wall of the first groove 101, and the axis of the connecting member 200 is perpendicular to the axis of the clamping base 100; the first rotating shaft 300 includes a first end 301 and a second end 302, the first end 301 is installed in the first groove 101, and the first end 301 is provided with an annular groove 303, which cooperates with the connecting member 200 , so that the first rotating shaft 300 rotates in a first reference plane, the first reference plane is perpendicular to the axis of the clamping base 100; the first fastener 410 is passed between the connecting member 200 and the outer surface of the clamping base 100, the end of the first fastener 410 abuts against the outer surface of the connecting member 200, and the axis of the first fastener 410, the axis of the connecting member 200 and the axis of the clamping base 100 are perpendicular to each other; one end of the second rotating shaft 500 is rotatably connected to the second end 302, and the other end of the second rotating shaft 500 is installed with an electrode 600.
[0040] The electrode clamping fixture provided by the present invention can realize rotation of the first rotating shaft 300 within a first reference plane by arranging the connecting member 200 between the annular groove 303 of the first rotating shaft 300 and the clamping base 100. The connecting member 200 can fix the rotated first rotating shaft 300 through the first fastener 410. The second rotating shaft 500 is rotatably connected to the first rotating shaft 300 to realize multi-angle adjustment of the electrode 600. The fixture has a large number of adjustment angles for the electrode 600, is easy to operate, and has a simple connection structure, which is easy to install and manufacture.
[0041] The following is a detailed description of the various parts of the electrode clamping fixture provided by the embodiment of the present disclosure with reference to the accompanying drawings:
[0042] In the embodiments provided in the present disclosure, Figures 1 to 6 As shown, the fixture includes a clamping base 100, one end of which is provided with a first groove 101. The clamping base 100 is a bridge connecting the machine tool body and the electrode 600. The clamping base 100 can be in a cube, rectangular parallelepiped or other external structure to meet the matching requirements of the machine tool body.
[0043] The fixture includes a first rotating shaft 300, such as Figure 1 As shown, the first rotating shaft 300 includes a first end 301 and a second end 302, and the first end 301 is installed in the first groove 101. The first groove 101 matches the shape of the first end 301. If the first end 301 is cylindrical or quasi-cylindrical, the first groove 101 is a cylindrical groove or a quasi-cylindrical groove, and the outer diameter of the first end 301 is the same or substantially the same as the inner diameter of the first groove 101, so that the first end 301 can be inserted into the first groove 101, realizing the connection between the first rotating shaft 300 and the clamping base 100, and at the same time, the first end 301 can rotate in the first groove 101.
[0044] In order to prevent the first rotating shaft 300 from falling out of the first groove 101, Figure 1 、 Figure 2 、 Figure 5 and Figure 6As shown, the fixture further includes a connector 200, which is a cylindrical structure. The connector 200 is inserted into the clamping base 100 and is disposed on the sidewall of the first groove 101. The axis of the connector 200 is perpendicular to the axis of the clamping base 100. In addition, an annular groove 303 is provided on the outer surface of the first end 301. The connector 200 cooperates with the annular groove 303. On the one hand, the connector 200 can confine the first rotation axis 300 within the first groove 101. On the other hand, due to the cooperation between the annular groove 303 and the outer surface of the connector 200, the connector 200 does not restrict the rotation of the first rotation axis 300 within the first reference plane. This ensures the connection between the first rotation axis 300 and the clamping base 100 and enables the rotation of the first rotation axis 300 within the first reference plane. The first reference plane is perpendicular to the axis of the clamping base 100.
[0045] The number of connectors 200 is at least one, but to ensure the limiting function of the connector 200 and the connection between the connector 200 and the annular groove 303, the number of connectors 200 generally needs to be greater than or equal to two. The following embodiment uses two connectors 200 as an example for description, but the number of connectors 200 in the fixture structure provided by the present disclosure is not limited to two. When the number of connectors 200 is greater than two, the layout and connection of multiple connectors 200 on the clamping base 100 can be adaptively deformed and adjusted, all within the scope of protection of the present disclosure.
[0046] The connector 200 includes a first sub-connector 201 and a second sub-connector 202 arranged in parallel, with a first end 301 disposed between the first sub-connector 201 and the second sub-connector 202. The outer surfaces of the first and second sub-connectors 201, 202 that contact the annular groove 303 may be smooth to facilitate rotation of the first end 301 within the first groove 101. The first and second sub-connectors 201, 202 may be structural components such as pins, inserted into the clamping base 100, arranged parallel to each other, and the distance between them may be equal to or slightly greater than the inner diameter of the annular groove 303, so that both the first and second sub-connectors 201, 202 can mate with the annular groove 303.
[0047] When the first rotating shaft 300 rotates to a preset position or a preset angle, the position or the preset angle of the first rotating shaft 300 needs to be fixed. Figures 1 to 3 As shown, combined Figure 5 and Figure 6The fixture also includes a first fastener 410, which is inserted between the connecting member 200 and the outer surface of the clamping base 100. The end of the first fastener 410 abuts against the outer surface of the connecting member 200. The axis of the first fastener 410, the axis of the connecting member 200 and the axis of the clamping base 100 are perpendicular to each other.
[0048] There is at least one first fastener 410, and the number of first fasteners 410 may correspond to the number of connectors 200, with the connectors 200 and the first fasteners 410 being in a one-to-one correspondence. The end of each first fastener 410 abuts against the outer surface of the corresponding connector 200. The first fastener 410 and the clamping base 100 may be connected by a thread. For example, the first fastener 410 may be a screw and a nut assembly, wherein a thread is provided on the surface of the clamping base 100 that abuts against the first fastener 410. The screw may be inserted into the clamping base 100, and the end of the screw abuts against the connector 200. When the position of the first rotating shaft 300 needs to be fixed, the nut may be rotated in a direction close to the connector 200, so that the first fastener 410 presses the connector 200, causing the connector 200 to move toward the axis of the first rotating shaft 300, thereby clamping and fixing the first rotating shaft 300. When the position or angle of the first rotating shaft 300 needs to be adjusted again, the nut can be rotated in a direction away from the connecting member 200 to adjust the position and angle of the first rotating shaft 300 .
[0049] In order to make the first rotating shaft 300 bear the force evenly and increase the service life of the fastener, the first fastener 410 includes a first sub-fastener 411 and a second sub-fastener 412. The end of the first sub-fastener 411 abuts against the outer surface of the first sub-connector 201, and the end of the second sub-fastener 412 abuts against the outer surface of the second sub-connector 202, so that the first fasteners 410 are evenly distributed in the clamping base 100, thereby increasing the service life of each first fastener 410.
[0050] In the embodiments provided in the present disclosure, Figure 2 As shown in Figure 4, the fixture also includes a graduated member 310, which is disposed on the outer surface of the first rotating shaft 300 and is located between the first end 301 and the second end 302. To improve the accuracy of the angle adjustment of the first rotating shaft 300, the graduated member 310 can be disposed in the outer axis direction of the first rotating shaft 300. The graduated member 310 can be annular in structure and have a scale on its outer surface to facilitate precise angle adjustment and visualize the adjusted angle. The scale values on the graduated member 310 can range from 0° to 360°, or different scale values can be selected based on the actual design requirements of the structure.
[0051] The indexing member 310 can be mounted on the outside of the first rotating center, with one end of the indexing member 310 abutting against the surface of the clamping base 100. To secure the indexing member 310 in the fixture and prevent it from falling off, a stepped structure can be provided at the end of the first groove 101. A step that matches the stepped structure can also be provided at the end of the indexing member 310. The stepped structure and the step cooperate to secure the position of the indexing member 310.
[0052] In the embodiments provided in the present disclosure, Figures 1 to 6 As shown, the fixture further includes a second rotating shaft 500, one end of which is rotatably connected to the second end portion 302, and the other end of the second rotating shaft 500 is mounted with an electrode 600. Figure 2 and Figure 4 As shown, the second end 302 of the first rotating shaft 300 can be a dividing head 320. Along the axis of the first rotating shaft 300, a second groove 321 is formed on the dividing head 320. The second rotating shaft 500 is inserted into the second groove 321. The second rotating shaft 500 can rotate along the second reference plane within the second groove 321. The second reference plane is perpendicular to the first reference plane and is the plane where the axis of the clamping base 100 lies.
[0053] The dividing head 320 may have two parallel planes. To improve the accuracy of the angle adjustment of the first rotation axis 300 within the second reference plane and to visualize the adjusted angle, a scale may be provided on at least one outer surface of the dividing head 320. The scale values provided on the outer surface of the dividing head 320 may range from 0° to 180°, from -90° to 90°, or other scale values selected based on structural design requirements.
[0054] Among them, such as Figures 1 to 3 As shown, combined Figure 5 and Figure 6 The fixture also includes a second fastener 420. A first connecting through hole is opened on the dividing head 320, and a second connecting through hole is opened on the second rotating shaft 500. The second fastener 420 is inserted into the first connecting through hole and the second connecting through hole to connect the dividing head 320 and the second rotating shaft 500.
[0055] The outer surface of the second fastener 420 in contact with the second rotating shaft 500 is a smooth surface, so that the second rotating shaft 500 can rotate within the second reference plane to adjust the angle of the electrode 600. In order to improve the clamping effect of the second fastener 420, the second fastener 420 can be a combination of a screw and a nut, wherein the screw can be passed through the first connection hole 421 and the second connection hole 501, and the outer surface of the screw in contact with the second rotating shaft 500 must be a smooth surface. After the second rotating shaft 500 is adjusted to a preset position or a preset angle, the position or angle of the second rotating shaft 500 needs to be fixed. At this time, the nut can be rotated in a direction close to the screw cap so that the second fastener 420 provides a clamping force for the indexing head 320 and the second rotating shaft 500 to fix the position or angle of the second rotating shaft 500. When the position or angle of the second rotating shaft 500 needs to be readjusted, the nut can be rotated in a direction away from the screw cap to adjust the position or angle of the second rotating shaft 500 again.
[0056] In the embodiments provided in the present disclosure, Figure 1 and Figure 5 As shown, the end of the second rotating shaft 500 connected to the electrode 600 is provided with a third groove 611, and the electrode 600 is installed in the third groove 611. In order to connect the electrode 600 and the second rotating shaft 500 and avoid damage to the electrode 600, as shown in FIG. Figure 1 and Figure 5 As shown, the fixture further includes an elastic collet 610, which is located between the third groove 611 and the electrode 600. The elastic collet 610 can be a circular elastic structure that can cooperate with the inner surface of the third groove 611. When installing the electrode 600, one end of the electrode 600 can be inserted into the elastic collet 610, and the connection between the second rotating shaft 500 and the electrode 600 is achieved through the elastic collet 610.
[0057] In order to prevent the electrode 600 from falling out of the third groove 611 and improve the fixation of the electrode 600 on the fixture, the fixture further includes a third fastener 430, such as Figures 1 to 3 As shown, combined Figure 5 and Figure 6The third fastener 430 is inserted between the elastic collet 610 and the outer surface of the second rotating shaft 500, and the axis of the third fastener 430 is perpendicular to the axis of the electrode 600. The third fastener 430 can be a structure such as a screw, and a thread can be provided at the position where the second rotating shaft 500 and the third fastener 430 are matched. By screwing the screw into the thread, the third fastener 430 and the second rotating shaft 500 form a threaded connection relationship. By tightening the third fastener 430, an external force can be provided to the elastic collet 610, so that the elastic collet 610 clamps the end of the electrode 600. By rotating the third fastener 430, the electrode 600 can be removed from the second rotating shaft 500 to replace an electrode 600 of a different model.
[0058] After the electrode 600 is fixed to the second rotating shaft 500, if the angle of the electrode 600 within the first reference plane needs to be adjusted, the first fastener 410 can be loosened. After adjusting to an appropriate position or angle, the first fastener 410 can be tightened to fix the angle of the electrode 600 within the first reference plane. If the angle of the electrode 600 within the second reference plane needs to be adjusted, the second fastener 420 can be loosened. After adjusting to an appropriate position or angle, the second fastener 420 can be tightened to fix the angle of the electrode 600 within the second reference plane. The angle and position of the electrode 600 can be adaptively adjusted according to processing requirements.
[0059] The electrode 600 clamping fixture provided by the present invention can realize rotation of the first rotating shaft 300 within a first reference plane by arranging the connecting member 200 between the annular groove 303 of the first rotating shaft 300 and the clamping base 100. The connecting member 200 can fix the rotated first rotating shaft 300 through the first fastener 410. The second rotating shaft 500 is rotatably connected to the first rotating shaft 300, so that the electrode 600 can be adjusted at multiple angles. The fixture has a large number of adjustment angles for the electrode 600, is easy to operate, and has a simple connection structure, which is easy to install and manufacture.
[0060] The disclosed embodiments provide an electric spark machine tool including the electrode clamping fixture. The machine tool can achieve multi-angle adjustment of the electrode, has strong operability, and has a high yield rate for manufactured products.
