Description

Technical Field

[0001] This utility model relates to a hinged universal electrode adjustment frame, belonging to the technical field of electrical discharge machining equipment. Background Technology

[0002] Before electrical discharge machining (EDM), the electrode mounting position generally needs to be corrected using a universal electrode adjustment frame (also known as an "electrode alignment head" or "adjustment frame"). A typical universal electrode adjustment frame includes a Z-axis rotary adjustment structure and an XY-axis horizontal adjustment structure. The XY-axis horizontal adjustment structure usually consists of a spherical hinge structure and four adjusting screws. Two of the screws, arranged opposite each other, are used to adjust the X-axis horizontal tilt angle, and the other two are used to adjust the Y-axis horizontal tilt angle. However, because all four screws lock the spherical hinge structure together, the Y-axis horizontal tilt angle may also change when adjusting the X-axis horizontal tilt angle, and vice versa. This often requires repeated adjustments and corrections, affecting electrode alignment efficiency and demanding a high level of skill from the operator.

[0003] For example, Chinese patent document CN221966963U discloses a chuck for mounting electrodes on an EDM machine tool, including a fixed plate and an adjusting part movably disposed below the fixed plate. The adjusting part includes a connecting shaft and a first bearing. The connecting shaft is disposed inside the fixed plate, and the first bearing is sleeved on the connecting shaft and located between the connecting shaft and the fixed plate. The inner and outer rings of the first bearing are respectively in contact with the connecting shaft and the fixed plate. The adjusting part also includes a second bearing for connecting the connecting shaft and the adjusting plate. The second bearing is a radial spherical bearing, wherein the second bearing includes a spherical inner ring with an outer spherical surface and a ball-hole outer ring with an inner spherical surface. The spherical inner ring and the ball-hole outer ring are used in conjunction, and the ball-hole outer ring is disposed on the adjusting part. Inside the disc, a spherical inner ring is fitted onto the connecting shaft and located within the outer ring of the spherical hole. Under the action of the outer ring of the spherical hole, the adjusting disc, chuck connecting block, and chuck can rotate around the spherical inner ring, allowing for easy adjustment of the adjusting disc, chuck connecting block, and chuck in various directions, thereby adjusting the position of the electrode. The adjusting disc is equipped with four second adjusting screws, connected from bottom to top, with one end abutting against the fixed plate. A first mounting hole is provided between two adjacent second adjusting screws, containing four springs. The angle adjusting plate has second mounting holes corresponding to the positions of the first mounting holes, with springs installed in both the first and second mounting holes. One end of each spring abuts against the first mounting hole of the adjusting disc, and the other end abuts against the second mounting hole of the angle adjusting plate. In this design, a spherical hinge structure is formed by the second bearing, and horizontal adjustment in the X and Y directions is achieved by adjusting the connection position of the four second adjusting screws.

[0004] Chinese patent document CN114289809A discloses a universal adjusting chuck for EDM electrodes, including a connecting assembly, a rotary adjusting assembly, a parallel adjusting assembly, and an electrode fixing seat. The rotary adjusting assembly includes a central shaft, a bushing, a washer spring, a hinged bearing, a rotary adjusting screw, a rotary adjusting rod, and an adjusting screw fixing seat. The parallel adjusting assembly includes a first parallel adjusting plate, a second parallel adjusting plate, and parallel adjusting steel balls. The first parallel adjusting plate is located below the bushing, the second parallel adjusting plate is located below the first parallel adjusting plate, and the parallel adjusting steel balls are located at the center between the first and second parallel adjusting plates. The electrode fixing seat is located below the second parallel adjusting plate. The parallel adjusting assembly in this design is used for horizontal adjustment in the XY directions. It consists of a spherical hinge structure formed by the parallel adjusting steel balls, and horizontal adjustment in the XY directions is achieved through the connection positions of four adjusting screws between the first and second parallel adjusting plates.

[0013] To make the Z-axis rotary adjustment structure more reliable, easier to manufacture and assemble, and more convenient for adjustment, a further preferred solution is as follows: the vertical central shaft is a Z-axis adjustment locking bolt. The tail end of the Z-axis adjustment locking bolt passes through the mating holes on the Y-axis horizontal adjustment mounting plate and the electrode clamp mounting plate from top to bottom, and is then connected to a Z-axis adjustment locking nut.

[0015] To facilitate XY-axis center adjustment during electrode calibration, a further preferred embodiment is as follows: An XY-axis center adjustment mechanism is mounted on the upper surface of the X-axis horizontal adjustment mounting plate.

Detailed Implementation

[0019] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0020] like Figures 1 to 9As shown, this utility model includes an electrode clamp mounting plate 1, a Y-axis horizontal adjustment mounting plate 2, and a horizontal adjustment support 3 arranged sequentially from bottom to top. The electrode clamp mounting plate 1 and the Y-axis horizontal adjustment mounting plate 2 are connected by a Z-axis rotation adjustment structure. The Z-axis rotation adjustment structure allows the electrode clamp mounting plate 1 and the Y-axis horizontal adjustment mounting plate 2 to rotate relative to each other around a vertical central axis 5 and be fixed in a set position. The electrode clamp mounting plate 1 can be used directly to fix and install electrodes, or it can be used to set electrodes by fixing and installing other clamps, as can be seen from various existing conventional technologies. In addition to the preferred embodiment described below, the Z-axis rotation adjustment structure can also be implemented by referring to various existing conventional technologies, such as the solutions in the two Chinese patent documents (CN221966963U and CN114289809A) mentioned in the background section above. "Vertical center axis 5" refers to the fact that its central axis is set vertically. The positional relationship between the various components described below is described with reference to "vertical center axis 5", that is, corresponding to the electrode clamp mounting plate 1 and the Y-axis horizontal adjustment mounting plate 2 being in a horizontal installation state. It can be understood that using "vertical center axis 5" as a reference state is only for the purpose of understanding the positional relationship between the various components in this utility model, so as to understand the technical solution of this utility model.

[0021] The first key technical point of this utility model is that the Y-direction horizontal adjustment mounting plate 2 and the horizontal adjustment support 3 are connected by a Y-direction horizontal adjustment mechanism. The Y-direction horizontal adjustment mechanism includes a Y-direction horizontal adjustment hinge shaft 6 and a Y-direction horizontal adjustment screw 7. The Y-direction horizontal adjustment mounting plate 2 and the horizontal adjustment support 3 can rotate relative to each other around the Y-direction horizontal adjustment hinge shaft 6. The axis of the Y-direction horizontal adjustment hinge shaft 6 is arranged horizontally in the left-right direction. The Y-direction horizontal adjustment screw 7 is set on the front and rear sides of the Y-direction horizontal adjustment hinge shaft 6. The Y-direction horizontal adjustment screw 7 is used to restrict the relative rotation of the Y-direction horizontal adjustment mounting plate 2 and the horizontal adjustment support 3 around the Y-direction horizontal adjustment hinge shaft 6.

[0022] In practice, when the tail ends of both Y-direction horizontal adjusting screws 7 are locked in contact with their corresponding force-bearing surfaces, the Y-direction horizontal adjusting mounting plate 2 and the horizontal adjusting support 3 cannot rotate relative to each other around the Y-direction horizontal adjusting hinge axis 6. When either Y-direction horizontal adjusting screw 7 is loosened, the Y-direction horizontal adjusting mounting plate 2 and the horizontal adjusting support 3 can rotate relative to each other around the Y-direction horizontal adjusting hinge axis 6. During the adjustment operation, usually both hands are used simultaneously: one hand is used to loosen one Y-direction horizontal adjusting screw 7, and the other hand is used to tighten the other Y-direction horizontal adjusting screw 7, thereby achieving rapid electrode calibration.

[0023] On the other hand, this utility model provides an X-direction horizontal adjustment mounting plate 4 above the horizontal adjustment support 3. The X-direction horizontal adjustment mounting plate 4 and the horizontal adjustment support 3 are connected by an X-direction horizontal adjustment mechanism. The X-direction horizontal adjustment mechanism includes an X-direction horizontal adjustment hinge shaft 8 and an X-direction horizontal adjustment screw 9. The X-direction horizontal adjustment mounting plate 4 and the horizontal adjustment support 3 can rotate relative to each other around the X-direction horizontal adjustment hinge shaft 8. The axis of the X-direction horizontal adjustment hinge shaft 8 is arranged horizontally in the front-back direction. The X-direction horizontal adjustment screw 9 is provided on the front and rear sides of the X-direction horizontal adjustment hinge shaft 8. The X-direction horizontal adjustment screw 9 is used to restrict the relative rotation of the X-direction horizontal adjustment mounting plate 4 and the horizontal adjustment support 3 around the X-direction horizontal adjustment hinge shaft 8.

[0024] Similarly, when the tail ends of both X-direction horizontal adjusting screws 9 are locked in contact with their corresponding force-bearing surfaces, the X-direction horizontal adjusting mounting plate 4 and the horizontal adjusting support 3 cannot rotate relative to each other around the X-direction horizontal adjusting hinge axis 8. When either X-direction horizontal adjusting screw 9 is loosened, the X-direction horizontal adjusting mounting plate 4 and the horizontal adjusting support 3 can rotate relative to each other around the Y-direction horizontal adjusting hinge axis 6. In specific adjustment operations, usually both hands are used simultaneously: one hand is used to loosen one X-direction horizontal adjusting screw 9, and the other hand is used to tighten the other X-direction horizontal adjusting screw 9, thereby achieving rapid electrode calibration.

[0025] This invention achieves X-axis horizontal adjustment for electrode calibration through independently set X-axis horizontal adjustment hinge shaft 8 and X-axis horizontal adjustment screw 9, and achieves Y-axis horizontal adjustment for electrode calibration through independently set Y-axis horizontal adjustment hinge shaft 6 and Y-axis horizontal adjustment screw 7. The X-axis and Y-axis horizontal adjustment mechanisms are set independently and do not affect each other. When performing electrode calibration, the operation is more convenient and efficient, and the technical requirements for the operator are relatively low.

[0026] In some preferred embodiments, the Y-axis horizontal adjustment hinge shaft 6 is fixedly disposed on the left and right sides of the Y-axis horizontal adjustment mounting plate 2. The lower surface of the horizontal adjustment support 3 is fixedly disposed with a Y-axis horizontal adjustment hinge support 10 corresponding to the Y-axis horizontal adjustment hinge shaft 6. The Y-axis horizontal adjustment hinge support 10 has a rotational fitting hole adapted to the Y-axis horizontal adjustment hinge shaft 6. The upper surface of the Y-axis horizontal adjustment mounting plate 2 has a first mounting groove. The lower end of the Y-axis horizontal adjustment hinge support 10 is embedded in the first mounting groove. The Y-axis horizontal adjustment hinge shaft 6 is connected to the side wall of the first mounting groove through a threaded connection structure. The upper surface of the Y-axis horizontal adjustment mounting plate 2 is fixedly disposed with a Y-axis horizontal adjustment force block 11 corresponding to the Y-axis horizontal adjustment screw 7. The lower surface of the horizontal adjustment support 3 is disposed with a first mounting cavity. The upper end of the Y-axis horizontal adjustment force block 11 is embedded in the first mounting cavity. The Y-axis horizontal adjustment screw 7 is connected to the side wall of the first mounting cavity. Both the Y-axis horizontal adjustment hinge support 10 and the Y-axis horizontal adjustment force-bearing block 11 adopt a partially embedded design, which can control the vertical height of the overall structure and make the spatial structure more compact. The Y-axis horizontal adjustment hinge shaft 6 is connected to the side wall of the first mounting groove through a threaded connection structure, that is, the outer peripheral surface of the Y-axis horizontal adjustment hinge shaft 6 is designed with an external thread structure, which corresponds to the internal thread structure on the Y-axis horizontal adjustment mounting plate 2. The outer peripheral surface of the Y-axis horizontal adjustment hinge shaft 6 is usually designed with a smooth rod part to form a rotational fit with the Y-axis horizontal adjustment hinge support 10. In some alternative embodiments, the two Y-axis horizontal adjustment hinge shafts 6 can also adopt an integral structure design. In other alternative embodiments, the Y-axis horizontal adjustment hinge shaft 6 and the Y-axis horizontal adjustment hinge support 10 can be interchanged, that is, the Y-axis horizontal adjustment hinge shaft 6 is fixed on the horizontal adjustment support 3, and the Y-axis horizontal adjustment hinge support 10 is fixed on the Y-axis horizontal adjustment mounting plate 2. Similarly, in some alternative embodiments, the Y-direction horizontal adjusting screw 7 and the Y-direction horizontal adjusting force block 11 can also be interchanged.

[0027] Similar to the design principle of the Y-axis horizontal adjustment mechanism, in some preferred embodiments, the X-axis horizontal adjustment hinge shaft 8 is fixedly disposed on the front and rear sides of the X-axis horizontal adjustment mounting plate 4. The upper surface of the horizontal adjustment support 3 is fixedly disposed with X-axis horizontal adjustment hinge supports 12 corresponding to the X-axis horizontal adjustment hinge shaft 8. The X-axis horizontal adjustment hinge supports 12 have rotational fitting holes adapted to the X-axis horizontal adjustment hinge shaft 8. The upper surface of the X-axis horizontal adjustment mounting plate 4 has a second mounting groove. The upper end of the X-axis horizontal adjustment hinge support 12 is embedded in the second mounting groove. The X-axis horizontal adjustment hinge shaft 8 is connected to the side wall of the second mounting groove through a threaded connection structure. The lower surface of the X-axis horizontal adjustment mounting plate 4 is fixedly disposed with X-axis horizontal adjustment force blocks 13 corresponding to the X-axis horizontal adjustment screws 9. The upper surface of the horizontal adjustment support 3 is provided with a second mounting cavity. The lower end of the X-axis horizontal adjustment force blocks 13 is embedded in the second mounting cavity. The X-axis horizontal adjustment screws 9 are connected to the side wall of the second mounting cavity. Both the X-axis horizontal adjustment hinge support 12 and the X-axis horizontal adjustment force block 13 adopt a partially embedded design, which can control the vertical height of the overall structure and make the spatial structure more compact. The X-axis horizontal adjustment hinge shaft 8 is connected to the side wall of the second mounting groove through a threaded connection structure, that is, the outer peripheral surface of the X-axis horizontal adjustment hinge shaft 8 is designed with an external thread structure, which can be connected to the internal thread structure on the X-axis horizontal adjustment mounting plate 4. The outer peripheral surface of the X-axis horizontal adjustment hinge shaft 8 is usually designed with a smooth rod part to form a rotational fit with the X-axis horizontal adjustment hinge support 12. In addition, the X-axis horizontal adjustment screw 9 and the Y-axis horizontal adjustment screw 7 are integrated into the horizontal adjustment support 3, which not only facilitates processing and assembly, but also makes it convenient for operators to rotate and operate the X-axis horizontal adjustment screw 9 and the Y-axis horizontal adjustment screw 7.

[0028] Similar to the design principle of the Y-axis horizontal adjustment mechanism, in some alternative embodiments, the two X-axis horizontal adjustment hinge shafts 8 can also be designed as a single unit. In some alternative embodiments, the X-axis horizontal adjustment hinge shaft 8 and the X-axis horizontal adjustment hinge support 12 can be interchanged. In some alternative embodiments, the X-axis horizontal adjustment screw 9 and the X-axis horizontal adjustment force block 13 can also be interchanged.

[0029] In some preferred embodiments, the axis of the Y-direction horizontal adjusting screw 7 is arranged at an angle relative to the horizontal plane, with the inner end of the axis higher than the outer end; similarly, the axis of the X-direction horizontal adjusting screw 9 is also arranged at an angle relative to the horizontal plane, with the inner end lower than the outer end. The angle between the X-direction horizontal adjusting screw 9 and the Y-direction horizontal adjusting screw 7 relative to the horizontal plane is typically designed to be around 10°. This structural layout not only results in a simple and reliable overall structure, but also minimizes the vertical space occupied by the outer ends of the X-direction horizontal adjusting screw 9 and the Y-direction horizontal adjusting screw 7, facilitating the overall layout design of the components and reducing spatial collisions and interference.

[0030] In some preferred embodiments, the inner end face of the Y-direction horizontal adjusting screw 7 is a spherical arc surface; the inner end face of the X-direction horizontal adjusting screw 9 is a spherical arc surface. The spherical arc surface structure design of the inner ends of both the X-direction horizontal adjusting screw 9 and the Y-direction horizontal adjusting screw 7 can reduce the risk of damage to the force-bearing contact surface and improve the reliability of the limiting and locking structure.

[0031] In some preferred embodiments, the lower surface of the horizontal adjustment support 3 is provided with positioning grooves that correspond one-to-one with the upper end of the Y-direction horizontal adjustment hinge support 10. The horizontal adjustment support 3 and the Y-direction horizontal adjustment hinge support 10 are connected and fixed by the first vertical screw 38. This structural design facilitates processing and assembly, and is beneficial for achieving rapid and accurate positioning and installation of the Y-direction horizontal adjustment hinge support 10. In some alternative embodiments, the horizontal adjustment support 3 and the Y-direction horizontal adjustment hinge support 10 can also be integrally formed.

[0032] Similar to the fixed installation structure of the Y-direction horizontal adjustment hinge support 10, in some preferred embodiments, the upper surface of the Y-direction horizontal adjustment mounting plate 2 is provided with positioning grooves corresponding to the lower ends of the Y-direction horizontal adjustment force-bearing blocks 11, and the Y-direction horizontal adjustment mounting plate 2 and the Y-direction horizontal adjustment force-bearing blocks 11 are connected and fixed by the second vertical screw 39; the upper surface of the horizontal adjustment support 3 is provided with positioning grooves corresponding to the lower ends of the X-direction horizontal adjustment hinge support 12, and the horizontal adjustment support 3 and the X-direction horizontal adjustment hinge support 12 are connected and fixed by the third vertical screw 40; the lower surface of the X-direction horizontal adjustment mounting plate 4 is provided with positioning grooves corresponding to the upper ends of the X-direction horizontal adjustment force-bearing blocks 13, and the X-direction horizontal adjustment mounting plate 4 and the X-direction horizontal adjustment force-bearing blocks 13 are connected and fixed by the fourth vertical screw 41.

[0033] In some preferred embodiments, the vertical central shaft 5 is a Z-axis adjusting locking bolt. The tail end of the Z-axis adjusting locking bolt passes through the mating holes on the Y-axis horizontal adjusting mounting plate 2 and the electrode clamp mounting plate 1 from top to bottom, and is connected to a Z-axis adjusting locking nut 14. The mating hole on the electrode clamp mounting plate 1 through which the Z-axis adjusting locking bolt passes is a two-stage stepped hole, which includes a first stepped hole and a second stepped hole arranged coaxially. The first stepped hole intersects with the lower surface of the electrode clamp mounting plate 1, and the inner diameter of the first stepped hole is larger than the inner diameter of the second stepped hole. A Z-axis adjusting bearing 15 is coaxially fixedly installed in the second stepped hole. The inner peripheral wall of the second stepped hole and the outer wall of the Z-axis adjusting locking bolt are rotated together by the Z-axis adjusting bearing 15. The Z-axis adjusting locking nut 14 is disposed in the first stepped hole, and the upper end face of the Z-axis adjusting locking nut 14 and the first stepped hole are connected. The inner top walls are rotated together by the Z-axis adjusting first support ball 16, and the lower surface of the Y-axis horizontal adjusting mounting plate 2 and the upper surface of the electrode clamp mounting plate 1 are rotated together by the Z-axis adjusting second support ball 17. The Z-axis adjusting first support ball 16 and the Z-axis adjusting second support ball 17 are arranged in a ring around the vertical central axis 5. The Z-axis rotation adjustment structure also includes a Z-axis adjusting screw 18 and a Z-axis adjusting force column 19. The Z-axis adjusting force column 19 is located on one side of the vertical central axis 5, and the axes of the two are parallel. The upper surface of the electrode clamp mounting plate 1 is provided with a force column movable hole 20. The upper end of the Z-axis adjusting force column 19 is fixedly connected to the Y-axis horizontal adjusting mounting plate 2, and the lower end of the Z-axis adjusting force column 19 is inserted into the force column movable hole 20. The Z-axis adjusting screw 18 is threadedly connected to the two oppositely arranged side walls of the force column movable hole 20. In some preferred embodiments, the Z-axis adjusting force-bearing column 19 and the screw head of one of the second vertical screws 39 can be designed as an integral structure. The inner end of the Z-axis adjusting screw 18 is also preferably designed with a spherical arc surface structure.

[0034] The function of the movable hole 20 in the force-bearing column is to allow the Y-axis horizontal adjustment mounting plate 2 and the electrode clamp mounting plate 1 to rotate relative to each other within a certain angle range around the vertical central axis 5. Specifically, when the inner ends of both Z-axis adjusting screws 18 are locked against the outer circumference of the Z-axis adjusting force-bearing column 19, the Y-axis horizontal adjustment mounting plate 2 and the electrode clamp mounting plate 1 cannot rotate relative to each other around the vertical central axis 5. When either Z-axis adjusting screw 18 is loosened, the Y-axis horizontal adjustment mounting plate 2 and the electrode clamp mounting plate 1 can rotate relative to each other around the vertical central axis 5. In actual adjustment operations, usually both hands are used simultaneously: one hand is used to loosen one Z-axis adjusting screw 18, and the other hand is used to tighten the other Z-axis adjusting screw 18, thereby achieving rapid electrode calibration.

[0035] In some preferred embodiments, the outer peripheral surfaces of the Y-axis horizontal adjustment mounting plate 2 and the electrode clamp mounting plate 1 are provided with mutually cooperating angle indicator marks and angle scales at their contact points. This means that, of the two parts, the Y-axis horizontal adjustment mounting plate 2 and the electrode clamp mounting plate 1, one part is used to set the angle indicator marks, and the other part is used to set the angle scales. By observing the relative positions of the angle indicator marks on the angle scales, the adjustment angle of the Z-axis rotation adjustment structure can be visually observed.

[0036] In some preferred embodiments, an XY center adjustment mechanism is mounted on the upper surface of the X-direction horizontal adjustment mounting plate 4. The XY center adjustment mechanism includes a center adjustment support ring 21, an X-direction center adjustment slider 22, a Y-direction center adjustment slider 23, a center adjustment fixing plate 24, a positioning plate mounting plate 25, and a center adjustment locking bolt 26. With the upper surface of the X-direction horizontal adjustment mounting plate 4 horizontally positioned as a reference state, the lower surface of the center adjustment support ring 21 is in contact with the upper surface of the X-direction horizontal adjustment mounting plate 4, and the lower surface of the Y-direction center adjustment slider 23 is in contact with the upper surface of the center adjustment support ring 21. The Y-direction center adjustment slider 23, the center adjustment support ring 21, and the X-direction center adjustment support ring 22 are all connected. The horizontal adjustment mounting plate 4 is fixedly connected as a whole. The Y-direction center adjustment slider 23 is sleeved in the inner cavity of the X-direction center adjustment slider 22, and the Y-direction center adjustment slider 23 and the X-direction center adjustment slider 22 are connected by a Y-direction screw and nut sliding pair, so that the Y-direction center adjustment slider 23 can move relative to the X-direction center adjustment slider 22 in the front-back direction. The Y-direction screw and nut sliding pair includes a Y-direction center adjustment screw 29, a Y-direction center adjustment nut 30, and a Y-direction sliding pair. The Y-direction center adjustment screw 29 is rotatably mounted on the inner cavity side wall of the X-direction center adjustment slider 22, and the Y-direction center adjustment nut 30 is fixedly set on the Y-direction center adjustment slider 23. The inner cavity sidewall of the fixed plate 24 has a clearance hole that matches the outer end of the Y-direction center adjusting screw 29 (the outer end of the Y-direction center adjusting screw 29 can move left and right within the clearance hole, and the Y-direction center adjusting screw 29 can be rotated using a wrench in the area of ​​the clearance hole). The Y-direction sliding pair is composed of the left and right sidewalls of the Y-direction center adjusting slider 23 and the left and right sidewalls of the inner cavity of the X-direction center adjusting slider 22. The left and right sidewalls of the Y-direction center adjusting slider 23 are symmetrical inclined surfaces with a left-right distance at the upper end smaller than the left-right distance at the lower end. The X-direction center adjusting slider 22 is sleeved in the inner cavity of the center adjusting fixed plate 24, and the X-direction center adjusting slider 22 and the center adjusting fixed plate 24 are connected by an X-direction screw. The screw and nut sliding joint is connected to allow the X-direction center adjustment slider 22 to move relative to the center adjustment fixed plate 24 in the front-back direction. The X-direction screw and nut sliding joint includes an X-direction center adjustment screw 31, an X-direction center adjustment nut 32, and an X-direction sliding joint. The X-direction center adjustment screw 31 is rotatably mounted on the inner cavity side wall of the center adjustment fixed plate 24. The X-direction center adjustment nut 32 is fixedly mounted on the Y-direction center adjustment slider 23. The X-direction sliding joint is composed of the front and rear side walls of the X-direction center adjustment slider 22 and the front and rear side walls of the inner cavity of the center adjustment fixed plate 24. The front and rear side walls of the X-direction center adjustment slider 22 are symmetrical inclined surfaces with a front-back distance at the upper end smaller than the front-back distance at the lower end.The center adjustment fixing plate 24 and the positioning plate mounting plate 25 are fixedly connected as a whole. The upper surface of the X-direction center adjustment slider 22 and the lower surface of the positioning plate mounting plate 25 form rolling contact through the X-direction center adjustment support ball 27. The upper surface of the Y-direction center adjustment slider 23 and the lower surface of the positioning plate mounting plate 25 form rolling contact through the Y-direction center adjustment support ball 28. The tail end of the center adjustment locking bolt 26 passes through the mating hole of the Y-direction center adjustment slider 23 and the mating hole of the positioning plate mounting plate 25 from bottom to top and is connected to the center adjustment locking nut 33. A non-rotatable sliding fit is formed between the center adjustment locking bolt 26 and the mating hole of the Y-direction center adjustment slider 23. A bolt preload disc spring 34 is provided between the lower end face of the locking nut 33 and the positioning plate mounting plate 25. The bolt preload disc spring 34 is sleeved on the outer periphery of the center adjusting locking bolt 26. A center adjusting locking worm gear 35 is fixedly sleeved on the outer periphery of the center adjusting locking nut 33. A center adjusting locking worm 36 with a horizontally oriented axis is rotatably mounted on the positioning plate mounting plate 25. The center adjusting locking worm gear 35 and the center adjusting locking worm 36 cooperate to form a worm gear transmission mechanism. Rotating tool interfaces are respectively provided at the outer ends of the Y-direction center adjusting screw 29, the X-direction center adjusting screw 31, and the center adjusting locking worm 36. The rotating tool interfaces are used to connect wrenches, and are usually preferably in the form of internal hexagonal sockets.

[0037] During assembly, the inner axial end of the X-axis center adjusting screw 31 can be positioned and limited by the positioning groove on the center adjusting fixed plate 24, and the outer axial end of the X-axis center adjusting screw 31 can be positioned and limited by the X-axis screw limiting sleeve 44 fixedly installed on the center adjusting fixed plate 24, so that the X-axis center adjusting screw 31 can only rotate relative to the center adjusting fixed plate 24 and will not move axially. The positioning and limiting structure of the Y-axis center adjusting screw 29 can be realized by combining the Y-axis screw positioning sleeve 45 and the Y-axis screw limiting sleeve 46. Both the Y-axis screw positioning sleeve 45 and the Y-axis screw limiting sleeve 46 are fixedly installed relative to the X-axis center adjusting slider 22, so that the Y-axis center adjusting screw 29 can only rotate relative to the X-axis center adjusting slider 22 and will not move axially.

[0038] During the adjustment operation, after inserting a wrench into the rotating tool interface at the outer end of the center adjusting locking worm 36, the center adjusting locking worm 36 can be rotated. This, in turn, drives the center adjusting locking nut 33 to rotate via the worm gear transmission mechanism. Because a non-rotating sliding fit is formed between the center adjusting locking bolt 26 and the Y-axis center adjusting slider 23, the center adjusting locking bolt 26 cannot rotate with the center adjusting locking nut 33 and can only move axially, thus achieving the tightening and loosening of the center adjusting locking bolt 26. When the center adjusting locking bolt 26 is loosened, depending on the actual state of the electrode and the workpiece to be processed, rotating the Y-axis center adjusting screw 29 will drive the Y-axis center adjusting slider 23 to move in the front-back direction. Rotating the X-axis center adjusting screw 31 will drive the X-axis center adjusting slider 22 and the Y-axis center adjusting slider 23 to move together in the left-right direction. Since the Y-axis center adjustment slider 23, the center adjustment support ring 21, and the X-axis horizontal adjustment mounting plate 4 are fixedly connected as a whole, during the above adjustment process, the electrode and the entire X-axis horizontal adjustment mounting plate 4 will move synchronously with the Y-axis center adjustment slider 23, thereby adjusting the center position of the electrode. This ensures that the clamping center of the electrode and the workpiece to be processed is aligned with the spindle of the equipment being used (EDM machine, lathe, five-axis rotary table) in any state. After completing the electrode center adjustment, the center adjustment locking worm 36 can be rotated in the reverse direction to lock the center adjustment locking nut 33 and the center adjustment locking bolt 26. Because the worm gear transmission mechanism has a self-locking function, the overall structure can maintain good stability after the electrode center adjustment is completed.

[0039] In some preferred embodiments, the Y-axis center adjustment slider 23 and the center adjustment support ring 21 are connected by a positioning pin 37, and the Y-axis center adjustment slider 23 and the X-axis horizontal adjustment mounting plate 4 are connected by a fifth vertical screw 42; the center adjustment fixing plate 24 and the positioning plate mounting plate 25 are connected by a sixth vertical screw 43. This structural design facilitates processing and assembly.

For example, after electrode wear, it can be overhauled on a CNC machine tool along with the aforementioned hinged universal electrode adjustment frame. This utility model can be used in fields such as slow wire EDM, medium-speed wire EDM, EDM, machining centers, and engraving machines.
