Abstract
Description

[0002] Currently, the FORM 2000 VHP CNC EDM machine, SE1 machine, and SA20 machine only have one electrode clamping mechanism. Due to the limitations of the electrode clamping structure, only one shape of electrode can be processed on a part at a time. For multi-variety, small-batch products, the EDM machine must stop and wait during the inspection and measurement process after one piece is debugged, resulting in low production efficiency. The FORM 2000 VHP CNC EDM machine is a high-end, precision machining equipment widely used in mold manufacturing and metal parts processing. The SE1 machine refers to the AgieCharmilles brand CNC precision EDM forming machine, and the SA20 machine is an EDM forming machine tool from the AgieCharmilles brand.
[0003] For the two types of machine tools mentioned above, the following problems exist when changing electrodes during the production process:
[0004] 1. Only one type of electrode can be armored at a time. Each time the electrode is changed, it needs to be aligned and the perpendicularity and angle of the electrode to the workpiece need to be adjusted, which affects the electrode changing efficiency.
[0005] 2. For electrical discharge machining of a single workpiece with multiple shapes, electrode measurement and inspection are required between multiple processes. The long waiting time for measurement and inspection affects the efficiency of electrode replacement.
[0006] 3. Frequent changes and adjustments to parameters such as electrode angles are cumbersome and affect the efficiency of electrode replacement.
[0007] In summary, the existing technology suffers from low electrode replacement efficiency. Summary of the Invention
[0008] The purpose of this invention is to provide a multi-directional adjustable electrode fixture and its method of use for easy electrode replacement, so as to solve the technical problem of low electrode replacement efficiency. This invention is easy to operate, convenient for electrode replacement, and can achieve precise electrode alignment. It eliminates the need for reciprocating alignment during multi-process machining, which is conducive to improving electrode replacement efficiency.
[0009] To achieve the above objectives, the present invention employs the following technical solution:
[0010] This invention discloses a multi-directional adjustable electrode clamp that facilitates electrode replacement, including a multi-directional adjustment mechanism. The multi-directional adjustment mechanism is provided with 3R locking pins. The multi-directional adjustment mechanism is detachably and fixedly connected to an electrode clamp, which is used to fix and connect the electrode.
[0011] Furthermore, the multi-directional adjustment mechanism includes an adjustment seat and a mounting seat. The adjustment seat is provided with a convex spherical surface and a 3R locking pin, and the mounting seat is provided with a ball socket, in which the convex spherical surface is movably embedded.
[0012] The adjusting seat has several bean-shaped slots located on the same circumference. The line connecting the center of the bean-shaped slots with the center of the convex spherical surface is perpendicular to the plane where the bean-shaped slots are located. A first adjusting pin is inserted into the bean-shaped slots and is connected to the mounting seat by a thread.
[0013] The adjusting seat is provided with at least one set of second adjusting pin mounting seats, each set of second adjusting pin mounting seats consists of two, and a second adjusting pin is respectively passed through the two second adjusting pin mounting seats. The second adjusting pin and the second adjusting pin mounting seat are connected by threads. A support pin is provided between the two second adjusting pins. The support pin contacts the second adjusting pin and is fixedly connected to the mounting seat.
[0014] Furthermore, the 3R locking rivet is detachably fixedly connected to the adjustment seat, and the 3R locking rivet has several annular grooves.
[0015] The centers of the plurality of bean-shaped grooves and the center of the convex spherical surface are located on the axis of the 3R locking stud.
[0016] Furthermore, the diameter of the convex spherical surface is the same as the diameter of the spherical socket.
[0017] Furthermore, a return spring is fitted onto the first adjusting pin. The return spring is located between the adjusting seat and the mounting seat, and the return spring is always in a compressed state.
[0018] Furthermore, there are four bean-shaped slots, which are arranged at equal intervals on the same circumference.
[0019] Furthermore, the second adjusting pin mounting base consists of two sets, which are symmetrically arranged about the center of the circumference of the several bean-shaped slots.
[0020] Furthermore, the mounting base has a detachable and fixed connection to the drill chuck, and the drill chuck can be detachably and fixedly connected to the electrode chuck.
[0021] Furthermore, the mounting base is provided with a Morse taper cam, the drill chuck is provided with a Morse taper groove, and the Morse taper cam is embedded in the Morse taper groove.
[0022] Based on the above structure, the present invention also discloses a method for using an electrode clamp that is multi-directionally adjustable and facilitates electrode replacement, comprising the following steps:
[0023] The electrode is fixed to the multi-directional adjustment mechanism using the corresponding electrode chuck. The multi-directional adjustment mechanism is then fixed to the machine tool spindle using 3R locking rivets. The position of the electrode is adjusted by adjusting the multi-directional adjustment mechanism.
[0024] In different processing steps of the same part, different electrode chucks can be replaced, and the corresponding electrodes can be installed on the replaced electrode chucks to achieve the installation of different types of electrodes.
[0025] Compared with the prior art, the present invention has the following beneficial effects:
[0026] 1. This invention includes an electrode chuck, a multi-directional adjustment mechanism, and a 3R locking rivet. The multi-directional adjustment mechanism is used for multi-directional adjustment of the electrode to achieve precise electrode alignment. The 3R locking rivet connects the entire fixture to the machine tool. The multi-directional adjustment mechanism is detachably and securely connected to the electrode chuck, which is used to securely connect the electrode. Since there are many types of electrodes, electrode chucks for various electrodes can be prepared in advance. By changing the electrode chuck, different types of electrodes can be quickly changed, making electrode replacement convenient. Furthermore, during multi-process machining, there is no need for reciprocating alignment; only the electrode chuck and the corresponding electrode need to be replaced, which improves electrode replacement efficiency. This invention is easy to operate, facilitates electrode replacement, achieves precise electrode alignment, and eliminates the need for reciprocating alignment during multi-process machining, thus improving electrode replacement efficiency.
[0027] 2. The present invention has a convex spherical surface on the adjustment seat and a ball socket on the mounting seat. The convex spherical surface is movably embedded in the ball socket, so that the adjustment seat can be tilted and rotated in multiple directions relative to the mounting seat, so that the electrode can be accurately positioned to the required angle and position, which is beneficial to the accurate alignment of the electrode.
[0028] 3. The adjusting base of the present invention has several bean-shaped slots. The design of the bean-shaped slots allows the first adjusting pin to have a certain range of movement in the slot, thereby allowing for fine adjustment of the position of the mounting base.
[0029] 4. In this invention, two second adjusting pins are respectively mounted on the two second adjusting pin mounting seats. The second adjusting pins are connected to the second adjusting pin mounting seats by threads. A support pin is provided between the two second adjusting pins, and the support pin contacts the second adjusting pins and is fixedly connected to the mounting seats. By rotating the second adjusting pins, the contact pressure between the support pin and the second adjusting pins is adjusted, thereby further fine-tuning the position of the mounting seats. At the same time, both sides of the support pin are in contact with the second adjusting pins, which is beneficial to the positioning of the mounting seats after adjustment.
[0030] 5. The mounting base of this invention is equipped with a Morse taper cam, and the drill chuck is equipped with a Morse taper groove, within which the Morse taper cam is embedded. The cooperation between the Morse taper cam and the groove ensures a tight connection between the drill chuck and the mounting base, thereby achieving high-precision positioning and fixation. During use, simply rotating the drill chuck allows for easy separation from the mounting base, facilitating quick electrode replacement and adjustment. Furthermore, the Morse taper fit has a high load-bearing capacity, capable of withstanding large axial and radial loads, ensuring the stability and reliability of the electrode during operation.
[0031] 6. The method of this invention fixes the electrode to a multi-directional adjustment mechanism using a corresponding electrode chuck. The multi-directional adjustment mechanism is then fixedly connected to the machine tool spindle using 3R locking rivets. By adjusting the multi-directional adjustment mechanism, the position of the electrode can be adjusted, achieving precise electrode alignment. In different machining processes of the same part, different electrode chucks can be used to install the corresponding electrodes, allowing for the installation of different electrode models. During multi-process machining, there is no need for repeated alignment; only the electrode chuck and the corresponding electrode need to be replaced, which improves electrode replacement efficiency.

[0038] The present invention will now be described in further detail with reference to the accompanying drawings:
[0039] See Figure 1 The present invention discloses an electrode clamp that is multi-directionally adjustable and easy to replace electrodes, including a multi-directional adjustment mechanism 6, which is used for multi-directional adjustment of the electrode 5 to achieve precise alignment of the electrode 5.

[0041] The multi-directional adjustment mechanism 6 is detachably and fixedly connected to the electrode chuck 4-1, which is used to fix the electrode 5. Since there are many types of electrodes 5, various electrode chucks 4-1 can be prepared in advance. By changing the electrode chuck 4-1, different types of electrodes 5 can be quickly replaced. Electrode 5 replacement is convenient, and no reciprocating alignment is required during multi-process processing, simplifying secondary clamping. Only the electrode chuck 4-1 and the corresponding electrode 5 need to be replaced, which is conducive to improving electrode replacement efficiency. Operators can make full use of the idle time of metrology and testing to perform continuous adjustment, programming, and preparation work for multiple processes, thereby improving efficiency.
[0042] In summary, this invention is easy to operate, the electrode 5 is easy to replace, and the electrode 5 can be accurately aligned. It eliminates the need for repeated alignment during multi-process machining, which is beneficial to improving the efficiency of electrode replacement.
[0043] Example 1:
[0044] See Figure 1 The present invention discloses an electrode clamp that is multi-directionally adjustable and easy to replace electrodes, including a multi-directional adjustment mechanism 6, wherein the multi-directional adjustment mechanism 6 is provided with a 3R locking pull pin 1, and the multi-directional adjustment mechanism 6 is detachably and fixedly connected to an electrode clamp 4-1, which is used to fix and connect an electrode 5.
[0045] Preferably, the multi-directional adjustment mechanism 6 includes an adjustment seat 2 and a mounting seat 3. The adjustment seat 2 is provided with a convex spherical surface 2-2 and a 3R locking pin 1. The mounting seat 3 is provided with a ball socket 3-1. The convex spherical surface 2-2 is movably embedded in the ball socket 3-1, so that the adjustment seat 2 can be tilted and rotated relative to the mounting seat 3 in multiple directions, so that the electrode can be accurately positioned to the required angle and position, which is beneficial to the accurate alignment of the electrode 5.
[0046] See Figure 2 The adjusting seat 2 has several bean-shaped slots 2-3 located on the same circumference. The line connecting the center of each bean-shaped slot 2-3 to the center of the convex spherical surface 2-2 is perpendicular to the plane containing the bean-shaped slots 2-3. A first adjusting pin 2-4 passes through each bean-shaped slot 2-3 and is threaded to the mounting seat 3. The design of the bean-shaped slots 2-3 allows the first adjusting pin 2-4 to have a certain range of movement within the slots, thereby enabling fine-tuning of the position of the mounting seat 3.
[0047] See Figure 1 and Figure 2 The adjusting seat 2 is provided with at least one set of second adjusting pin mounting seats 2-6, each set consisting of two seats. A second adjusting pin 2-5 is threaded through each of the two mounting seats 2-6, and the second adjusting pin 2-5 is connected to the mounting seat 2-6 by threads. A support pin 3-2 is provided between the two second adjusting pins 2-5, contacting the second adjusting pin 2-5 and being fixedly connected to the mounting seat 3. The contact pressure between the support pin 3-2 and the second adjusting pin is adjusted by rotating the second adjusting pin, thereby further fine-tuning the position of the mounting seat 3. Simultaneously, both sides of the support pin 3-2 contact the second adjusting pin 2-5, facilitating the positioning of the mounting seat 3 after adjustment.
[0048] Preferred, see Figure 1 The 3R locking rivet 1 is detachably and fixedly connected to the adjusting seat 2, and the 3R locking rivet 1 has several annular grooves.
[0049] The centers of the plurality of bean-shaped grooves 2-3 and the center of the convex spherical surface 2-2 are located on the axis of the 3R locking pin 1.
[0050] Preferably, the adjusting seat 2 is fixedly connected to the fixing seat 2-1 by bolts, and the 3R locking rivet 1 is provided with a top cap 1-1, which is located between the fixing seat 2-1 and the adjusting seat 2.
[0051] Preferably, the diameter of the convex spherical surface 2-2 is the same as the diameter of the spherical socket 3-1.

[0053] Preferred, see Figure 2 There are four bean-shaped slots 2-3, and the four bean-shaped slots 2-3 are arranged at equal intervals on the same circumference.
[0054] Preferred, see Figure 2 The second adjusting pin mounting base 2-6 consists of two sets, which are symmetrically arranged about the center of the circumference of the several bean-shaped slots 2-3, which is beneficial to the stability of the connection between the adjusting base 2 and the mounting base 3.

The Morse taper cam 3-3 is embedded in the Morse taper groove 4-2. The Morse taper is an internationally standardized taper with high precision and reliable positioning performance. The cooperation between the Morse taper cam and the groove ensures a tight connection between the drill chuck and the mounting base, achieving high-precision positioning and fixation. Furthermore, the Morse taper fit is easy to disassemble; simply rotating the drill chuck 4 allows for separation from the mounting base, facilitating quick electrode replacement and adjustment. Secondly, the Morse taper fit has a high load-bearing capacity, capable of withstanding large axial and radial loads, ensuring the stability and reliability of the electrode during operation.
[0057] In summary, the present invention has the following advantages:
[0058] 1. Multiple electrode clamps of various shapes can be prepared simultaneously for easy and quick replacement;
[0059] 2. Operators only need to adjust the electrode position and shape once, and the position is accurate and consistent with repeated clamping.

[0061] 4. It requires low operator skills, is easy to re-clamp, and has high positioning accuracy.
[0062] 5. This invention transforms the traditional single-spindle electrode head into a modular quick-change electrode assembly through a systematic management approach. That is, each type of electrode 5 corresponds to a matching electrode chuck 4-1, which significantly improves the replacement efficiency of electrode 5 and is conducive to improving processing efficiency.
[0063] This invention can achieve flexible conversion between two or more types of multi-form electrical discharge machining, with strong versatility, low cost, and high efficiency.
[0064] This invention expands the functionality of machine tools, truly realizing multi-electrode quick-change functionality, allowing for appropriate adjustments in both horizontal and vertical directions based on the actual state of the cutting tool. In numerous practical applications, due to its multi-tool capability, it can complete both roughing and finishing processes, and allows for immediate debugging of another part while metrology, inspection, and technical issues are being addressed. Machine tool utilization has increased from less than 35% to 90%, significantly improving production efficiency and greatly shortening the processing cycle.
[0065] Example 2:
[0066] See Figure 1 and Figure 2 This invention discloses a multi-directional adjustable electrode clamp that facilitates electrode replacement, comprising:
[0067] 3R Locking Pull Screw 1: The 3R Locking Pull Screw 1 connects to the spindle of the machine tool, enabling quick connection and disassembly between the machine tool and the fixture, and serves to ensure physical accuracy.
[0068] Multi-directional adjustment mechanism 6: Enables connection with 3R locking pin 1. Four sets of adjusting pins adjust the perpendicularity and angle between the electrode and the workpiece, ensuring the machining shape and position on the part.
[0069] Drill chuck: Used to hold the electrode rod.
[0070] The fixture installation steps in this embodiment are as follows:
[0071] S1. Connect the mounting base 3 and the adjusting base 2, and align the center of the ball socket 3-1 of the positioning base with the center of the φ30 ball of the adjusting base 2 within 0.005mm to ensure its positional accuracy. Secure it tightly with four first adjusting screws 2-4.
[0072] S2, adjusting seat 2 and mounting seat 3 are connected by a convex spherical surface and a ball socket of Sφ30 and four second adjusting pins 2-5. At the same time, two support pins 3-2 are installed between adjusting seat 2 and mounting seat 3.

[0074] S4. Cylindrical electrode rods, strip-shaped or square-handled electrodes can be clamped with various electrode chucks 4-1.
[0075] S5. Secure the assembled device to the EDM spindle manually or pneumatically using the 3R locking pin 1.
[0076] Based on the above structure, the present invention also discloses a method for using an electrode clamp that is multi-directionally adjustable and facilitates electrode replacement, see [link to relevant documentation]. Figure 3 This includes the following steps:
[0077] S1. Fix electrode 5 to multi-directional adjustment mechanism 6 via corresponding electrode chuck 4-1. Fix multi-directional adjustment mechanism 6 to machine tool spindle via 3R locking tie 1. Adjust multi-directional adjustment mechanism 6 to adjust the position of electrode 5, thereby achieving precise alignment of electrode 5.
[0078] S2. In different processing steps of the same part, different electrode chucks 4-1 can be replaced, and the corresponding electrode 5 can be installed on the replaced electrode chuck 4-1, thus enabling the installation of different types of electrodes 5. In multi-process processing, there is no need for repeated alignment; only the electrode chuck 4-1 and the corresponding electrode 5 need to be replaced, which improves electrode replacement efficiency.
[0079] Example 3:
[0080] This embodiment discloses a method for using a multi-directional adjustable electrode clamp that facilitates electrode replacement. See [link to documentation]. Figure 3 This includes the following steps:
[0081] S1. Fix electrode 5 to drill chuck 4 via corresponding electrode chuck 4-1 and place it on image tool setter;
[0082] S2. When the second adjusting pin 2-5 is rotated, the second adjusting pin 2-5 pushes the support pin 3-2, the support pin 3-2 drives the mounting seat 3 to rotate, and the mounting seat 3 rotates relative to the adjusting seat 2 through the convex spherical surface 2-2 and the ball socket 3-1. During the rotation, the adjusting seat 2 drives the first adjusting pin 2-4 to slide in the bean-shaped groove 2-3.
[0083] By tightening or loosening several first adjusting pins 2-4, the mounting base 3 rotates relative to the adjusting base 2 via the convex spherical surface 2-2 and the ball socket 3-1;
[0084] By adjusting the first adjusting pin 2-4 and the second adjusting pin 2-5, the adjusting seat 2 and the mounting seat 3 are rotated relative to each other. Then, the position of the electrode 5 is corrected by combining the image tool setting device, and the corrected electrode fixture is obtained.
[0085] S3. Install the calibrated electrode fixture on the machine tool spindle using the 3R locking pull pin 1. Adjust the first adjusting pin 2-4 and the second adjusting pin 2-5 to make the adjusting seat 2 rotate relative to the mounting seat 3, thereby adjusting the position of the electrode.
[0086] S4. In different processing steps of the same part, different types of electrodes 5 can be installed by changing different electrode chucks 4-1.
[0087] Example 4:
[0088] This embodiment discloses a method for using a multi-directional adjustable electrode clamp that facilitates electrode replacement, including the following steps:
[0089] S1. First, fix the 3R locking pin 1 onto the adjusting seat 2 manually using the clamp.
[0090] S2. Next, clamp the electrode 5 required for electrical discharge machining onto the drill chuck 4, visually check and correct the direction of the electrode machining, and then lock it.
[0091] S3. Place the fixture with electrode 5 mounted on the image tool setter and adjust the angular position of the electrode. Adjust the displacement in the X and Y directions by turning the first adjusting screws 2-4 at four points, i.e., adjust the tilt of the mounting base 3. Point 3 is a positioning adjusting screw, and point 1 is a locking screw. Rotation in the Z direction is adjusted by the second adjusting screws 2-6 at two points, i.e., adjust the rotation of the mounting base 3. Point 1 is a limit adjusting screw, and point 1 is a locking screw. By installing and adjusting the three degrees of freedom in the X, Y, and Z directions, the correct position of the electrode in space is ensured.
[0092] S4. Remove the calibrated fixture with electrodes from the 3R positioning base and install it on the EDM spindle manually or pneumatically. Calibrate the X, Y, and Z coordinates on the machine tool and store them in the machine tool coordinate system for processing.
[0093] S5. During use, the drill chuck 4 with the electrode installed is adjusted by turning the first adjusting pin 2-4 at point 4 to adjust the displacement in the X and Y directions. Point 3 is a positioning adjusting pin, and point 1 is a locking pin. Rotation in the Z direction is adjusted via the two second adjusting pin mounting seats 2-6, one of which is a limit adjusting pin, and the other is a locking pin. By installing and adjusting the three degrees of freedom in the X, Y, and Z directions, the correct spatial position of the electrode is ensured.
[0094] This invention enables multi-tool machining and allows for the simultaneous debugging and machining of two or more parts. That is, while part A is being measured and inspected, part B can be immediately debugged and machined through a quick-change device, which greatly reduces downtime, improves machine tool utilization, and shortens the production cycle.

Any modifications made to the technical solution based on the technical concept proposed in this invention shall fall within the scope of protection of the claims of this invention.
