Description

Technical Field

[0001] This utility model relates to a worm gear and worm shaft adjusting hinge type universal electrode adjusting bracket, 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. Utility Model Content

[0005] The technical problem to be solved by this utility model is to provide a worm gear and worm shaft adjusting hinge type universal electrode adjusting frame, which can more conveniently realize the horizontal adjustment during electrode calibration.

[0006] The technical solution adopted by this utility model to solve its technical problem is: a worm gear and worm shaft adjusting hinge type universal electrode adjusting frame, including an electrode clamp mounting plate, a first horizontal adjusting mounting block, and a rotary adjusting support seat arranged sequentially from bottom to top. The first horizontal adjusting mounting block and the rotary adjusting support seat are connected by a Z-axis rotary adjusting structure, which allows the first horizontal adjusting mounting block and the rotary adjusting support seat to rotate relative to each other around a vertical central axis and be fixed in a set position. A second horizontal adjusting mounting block is provided between the electrode clamp mounting plate and the first horizontal adjusting mounting block. The first horizontal adjusting mounting block and the second horizontal adjusting mounting block are connected by an X-axis horizontal adjusting mechanism, and the second horizontal adjusting mounting block is connected to the electrode clamp mounting plate by a Y-axis horizontal adjusting mechanism. The X-axis horizontal adjusting mechanism includes an X-axis horizontal adjusting hinge shaft, an X-axis horizontal adjusting gear and rack mechanism, and an X-axis horizontal adjusting worm gear and worm shaft mechanism. The X-axis horizontal adjusting gear and rack mechanism is used to drive the second horizontal adjusting mounting block and the first horizontal adjusting mounting block to rotate relative to each other around the X-axis horizontal adjusting hinge shaft. The hinge shaft's axis is horizontally arranged along the front-to-back direction. The X-axis horizontal adjustment gear and rack mechanism includes a mating X-axis horizontal adjustment gear and an X-axis horizontal adjustment rack. The X-axis horizontal adjustment worm gear mechanism includes a mating X-axis horizontal adjustment worm wheel and an X-axis horizontal adjustment worm. The X-axis horizontal adjustment gear and X-axis horizontal adjustment worm wheel are coaxially fixed. The X-axis horizontal adjustment worm is equipped with a rotating tool interface. The Y-axis horizontal adjustment mechanism is connected to the Y-axis horizontal adjustment hinge shaft, the Y-axis horizontal adjustment gear and rack mechanism, and the Y-axis horizontal adjustment worm gear mechanism. The adjusting gear and rack mechanism is used to drive the second horizontal adjusting mounting block and the electrode clamp mounting plate to rotate relative to each other around the Y-axis horizontal adjusting hinge axis. The axis of the Y-axis horizontal adjusting hinge axis is arranged horizontally in the left-right direction. The Y-axis horizontal adjusting gear and rack mechanism includes a mating Y-axis horizontal adjusting gear and a Y-axis horizontal adjusting rack. The Y-axis horizontal adjusting worm gear mechanism includes a mating Y-axis horizontal adjusting worm wheel and a Y-axis horizontal adjusting worm. The Y-axis horizontal adjusting gear and the Y-axis horizontal adjusting worm wheel are coaxially fixed. The Y-axis horizontal adjusting worm is equipped with a rotating tool interface.

[0007] In the above solution, this utility model achieves X-axis horizontal adjustment for electrode correction through independently configured X-axis horizontal adjustment hinge shaft, X-axis horizontal adjustment gear rack mechanism, and X-axis horizontal adjustment worm gear mechanism; and achieves Y-axis horizontal adjustment for electrode correction through independently configured Y-axis horizontal adjustment hinge shaft, Y-axis horizontal adjustment gear rack mechanism, and Y-axis horizontal adjustment worm gear mechanism. The X-axis and Y-axis horizontal adjustment mechanisms are independently configured and do not affect each other, making operation convenient, efficient, and requiring relatively low technical skills from operators during electrode correction. Both the X-axis and Y-axis horizontal adjustment worm gear mechanisms have self-locking functions, which effectively maintains the reliability of the adjustment structure. For X-axis horizontal adjustment, only a rotating tool (e.g., a wrench) is needed to rotate the X-axis horizontal adjustment worm; for Y-axis horizontal adjustment, only a rotating tool is needed to rotate the Y-axis horizontal adjustment worm. Typically, single-handed operation is sufficient, further enhancing the convenience of horizontal adjustment operations.

[0016] 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 hole on the first horizontal adjustment mounting block and the mating hole on the rotary adjustment support from bottom to top, and then connects to the Z-axis adjustment locking nut. The mating hole on the rotary adjustment support through which the Z-axis adjustment locking bolt passes is a two-stage stepped hole, which includes a first-stage hole and a second-stage hole arranged coaxially.

[0021] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0022] like Figures 1 to 11As shown, this utility model includes an electrode clamp mounting plate 1, a first horizontal adjustment mounting block 2, and a rotary adjustment support 3 arranged sequentially from bottom to top. The first horizontal adjustment mounting block 2 and the rotary adjustment support 3 are connected by a Z-axis rotary adjustment structure, which allows the first horizontal adjustment mounting block 2 and the rotary adjustment support 3 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 fix and install other clamps to set electrodes. Refer to various existing conventional technologies. In the embodiment shown in the figure, the electrode clamp mounting plate 1 is provided with clamp mounting screw holes 70 for fixing and installing other clamps to set electrodes. In addition to the preferred embodiment described below, the Z-axis rotary adjustment structure can also be implemented by referring to various existing conventional technologies. For example, it can be implemented by the schemes in the two Chinese patent documents (CN221966963U, 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 first horizontal adjustment mounting block 2 and the rotary adjustment support 3 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.

[0023] The first key technical point of this utility model is that a second horizontal adjustment mounting block 4 is provided between the electrode clamp mounting plate 1 and the first horizontal adjustment mounting block 2. The first horizontal adjustment mounting block 2 and the second horizontal adjustment mounting block 4 are connected by an X-axis horizontal adjustment mechanism, and the second horizontal adjustment mounting block 4 is connected to the electrode clamp mounting plate 1 by a Y-axis horizontal adjustment mechanism. The X-axis horizontal adjustment mechanism includes an X-axis horizontal adjustment hinge shaft 6, an X-axis horizontal adjustment gear and rack mechanism, and an X-axis horizontal adjustment worm gear mechanism. The X-axis horizontal adjustment gear and rack mechanism is used to drive the second horizontal adjustment mounting block 4 and the first horizontal adjustment mounting block 2 to rotate relative to each other around the X-axis horizontal adjustment hinge shaft 6. The axis of the X-axis horizontal adjustment hinge shaft 6 is arranged horizontally in the front-back direction. The X-axis horizontal adjustment gear and rack mechanism includes a mating X-axis horizontal adjustment gear 7 and an X-axis horizontal adjustment rack 8. The X-axis horizontal adjustment worm gear mechanism includes a mating X-axis horizontal adjustment worm gear. The X-axis horizontal adjusting worm gear 10, X-axis horizontal adjusting gear 7, and X-axis horizontal adjusting worm wheel 9 are coaxially fixed. The X-axis horizontal adjusting worm gear 10 is equipped with a rotating tool interface. The Y-axis horizontal adjusting mechanism includes a Y-axis horizontal adjusting hinge shaft 11, a Y-axis horizontal adjusting gear and rack mechanism, and a Y-axis horizontal adjusting worm wheel and worm gear mechanism. The Y-axis horizontal adjusting gear and rack mechanism is used to drive the second horizontal adjusting mounting block 4 and the electrode clamp mounting plate 1 to rotate relative to each other around the Y-axis horizontal adjusting hinge shaft 11. The axis of the Y-axis horizontal adjusting hinge shaft 11 is arranged horizontally in the left-right direction. The Y-axis horizontal adjusting gear and rack mechanism includes a mating Y-axis horizontal adjusting gear 12 and a Y-axis horizontal adjusting rack 13. The Y-axis horizontal adjusting worm wheel and worm gear mechanism includes a mating Y-axis horizontal adjusting worm wheel 14 and a Y-axis horizontal adjusting worm 15. The Y-axis horizontal adjusting gear 12 and the Y-axis horizontal adjusting worm wheel 14 are coaxially fixed. The Y-axis horizontal adjusting worm 15 is equipped with a rotating tool interface.

[0024] The rotating tool interface is used to connect to wrenches, and an internal hexagonal interface is usually preferred. The X-axis horizontal adjustment gear and rack mechanism is used to drive the second horizontal adjustment mounting block 4 and the first horizontal adjustment mounting block 2 to rotate relative to each other around the X-axis horizontal adjustment hinge shaft 6. That is, one component of the second horizontal adjustment mounting block 4 and the first horizontal adjustment mounting block 2 is used to install the X-axis horizontal adjustment gear 7, and the other component is used to install the X-axis horizontal adjustment rack 8. The relative motion trajectory between the X-axis horizontal adjustment gear 7 and the X-axis horizontal adjustment rack 8 should be consistent with the relative rotation trajectory between the second horizontal adjustment mounting block 4 and the first horizontal adjustment mounting block 2. The extension direction of the tooth transmission surface of the X-axis horizontal adjustment rack 8 can be set to a corresponding arc shape. Similarly, the Y-axis horizontal adjustment gear and rack mechanism is used to drive the second horizontal adjustment mounting block 4 and the electrode clamp mounting plate 1 to rotate relative to each other around the Y-axis horizontal adjustment hinge axis 11. That is, one of the components of the second horizontal adjustment mounting block 4 and the electrode clamp mounting plate 1 is used to install the Y-axis horizontal adjustment gear 12, and the other component is used to install the Y-axis horizontal adjustment rack 13. The relative motion trajectory between the Y-axis horizontal adjustment gear 12 and the Y-axis horizontal adjustment rack 13 should be consistent with the relative rotation trajectory between the second horizontal adjustment mounting block 4 and the electrode clamp mounting plate 1. The extension direction of the tooth transmission surface of the Y-axis horizontal adjustment rack 13 can be set to the corresponding arc shape.

[0025] In practical implementation, when the X-axis horizontal adjusting worm 10 is driven to rotate by a wrench, the X-axis horizontal adjusting worm wheel 9 and the X-axis horizontal adjusting gear 7 rotate synchronously, thereby causing the X-axis horizontal adjusting gear 7 and the X-axis horizontal adjusting rack 8 to move relative to each other. This achieves rotational adjustment between the first horizontal adjusting mounting block 2 and the second horizontal adjusting mounting block 4, i.e., X-axis horizontal adjustment. When the Y-axis horizontal adjusting worm 15 is driven to rotate by a wrench, the Y-axis horizontal adjusting worm wheel 14 and the Y-axis horizontal adjusting gear 12 rotate synchronously, thereby causing the Y-axis horizontal adjusting gear 12 and the Y-axis horizontal adjusting rack 13 to move relative to each other. This achieves rotational adjustment between the second horizontal adjusting mounting block 4 and the electrode clamp mounting plate 1, i.e., Y-axis horizontal adjustment.

[0026] This invention achieves X-axis horizontal adjustment for electrode correction through independently configured X-axis horizontal adjustment hinge shaft 6, X-axis horizontal adjustment gear and rack mechanism, and X-axis horizontal adjustment worm gear mechanism. Similarly, it achieves Y-axis horizontal adjustment for electrode correction through independently configured Y-axis horizontal adjustment hinge shaft 11, Y-axis horizontal adjustment gear and rack mechanism, and Y-axis horizontal adjustment worm gear mechanism. The X-axis and Y-axis horizontal adjustment mechanisms are independently configured and do not interfere with each other, making operation convenient, efficient, and requiring relatively low operator skill during electrode correction. Both the X-axis and Y-axis horizontal adjustment worm gear mechanisms have self-locking functions, ensuring good reliability of the adjustment structure. X-axis horizontal adjustment requires only rotating the X-axis horizontal adjustment worm 10 using a rotating tool (e.g., a wrench), while Y-axis horizontal adjustment requires only rotating the Y-axis horizontal adjustment worm 15. This typically allows for single-handed operation, further enhancing the convenience of horizontal adjustment.

[0027] In some preferred embodiments, to make the overall structure more compact and easier to process and assemble, the X-axis horizontal adjustment hinge shaft 6 is fixedly disposed on the front and rear sides of the second horizontal adjustment mounting block 4. The lower surface of the first horizontal adjustment mounting block 2 is fixedly provided with an X-axis horizontal adjustment hinge support 16 corresponding to the X-axis horizontal adjustment hinge shaft 6. The first horizontal adjustment mounting block 2 and the X-axis horizontal adjustment hinge support 16 are preferably designed as an integral structure (other fixed connection methods can also be used, such as screw connection). The X-axis horizontal adjustment hinge support 16 has a rotational fitting hole adapted to the X-axis horizontal adjustment hinge shaft 6. The upper surface of the second horizontal adjustment mounting block 4 has a first mounting groove. The lower end of the X-axis horizontal adjustment hinge support 16 is embedded in the first mounting groove, and the X-axis horizontal adjustment hinge shaft 6 is connected to the side wall of the first mounting groove through a threaded connection structure. The Y-axis horizontal adjustment hinge shaft 11 is fixedly set on the left and right sides of the second horizontal adjustment mounting block 4. The upper surface of the electrode clamp mounting plate 1 is fixedly set with Y-axis horizontal adjustment hinge supports 17 corresponding to the Y-axis horizontal adjustment hinge shaft 11. The electrode clamp mounting plate 1 and the Y-axis horizontal adjustment hinge support 17 are preferably designed as an integral structure (other fixed connection methods can also be used, such as screw connection). The Y-axis horizontal adjustment hinge support 17 has a rotation fit hole adapted to the Y-axis horizontal adjustment hinge shaft 11. The lower surface of the second horizontal adjustment mounting block 4 has a second mounting groove, and the upper end of the Y-axis horizontal adjustment hinge support 17 is embedded in the second mounting groove. The Y-axis horizontal adjustment hinge shaft 11 is connected to the side wall of the second mounting groove through a threaded connection structure. The X-axis horizontal adjustment hinge support 16 and the Y-axis horizontal adjustment hinge support 17 adopt a partially embedded design, which can control the vertical height of the overall structure and make the spatial structure more compact. The outer peripheral surface of the X-axis horizontal adjustment hinge shaft 6 is usually designed with a smooth rod portion to form a rotational engagement with the X-axis horizontal adjustment hinge support 16; the outer peripheral surface of the Y-axis horizontal adjustment hinge shaft 11 is usually designed with a smooth rod portion to form a rotational engagement with the Y-axis horizontal adjustment hinge support 17. In some alternative embodiments, the two X-axis horizontal adjustment hinge shafts 6 can also adopt an integral structure design. In other alternative embodiments, the X-axis horizontal adjustment hinge shaft 6 and the X-axis horizontal adjustment hinge support 16 can be interchanged, that is, the X-axis horizontal adjustment hinge shaft 6 is fixed on the first horizontal adjustment mounting block 2, and the X-axis horizontal adjustment hinge support 16 is fixed on the second horizontal adjustment mounting block 4. Similarly, in other alternative embodiments, the two Y-axis horizontal adjustment hinge shafts 11 can also adopt an integral structure design, and the Y-axis horizontal adjustment hinge shaft 11 and the Y-axis horizontal adjustment hinge support 17 can also be interchanged.

[0028] In some preferred embodiments, to make the overall structure more compact and easier to process and assemble, the X-axis horizontal adjusting gear 7 and the X-axis horizontal adjusting worm 10 are both rotatably mounted on the second horizontal adjusting mounting block 4, the X-axis horizontal adjusting rack 8 is fixedly mounted on the lower end of the first horizontal adjusting mounting block 2, the Y-axis horizontal adjusting gear 12 and the Y-axis horizontal adjusting worm 15 are both rotatably mounted on the second horizontal adjusting mounting block 4, and the Y-axis horizontal adjusting rack 13 is fixedly mounted on the upper end of the electrode clamp mounting plate 1. Integrating the X-axis horizontal adjusting gear 7, the X-axis horizontal adjusting worm 10, the Y-axis horizontal adjusting gear 12, and the Y-axis horizontal adjusting worm 15 into the second horizontal adjusting mounting block 4 not only facilitates processing and assembly but also allows operators to easily rotate and operate the X-axis horizontal adjusting worm 10 and the Y-axis horizontal adjusting worm 15. To further facilitate assembly, in some preferred embodiments, the lower surface of the first horizontal adjustment mounting block 2 is provided with a positioning groove corresponding to the upper end of the X-direction horizontal adjustment rack 8, and the first horizontal adjustment mounting block 2 and the X-direction horizontal adjustment rack 8 are connected and fixed by a first vertical screw 26; the upper surface of the electrode clamp mounting plate 1 is provided with a positioning groove corresponding to the lower end of the Y-direction horizontal adjustment rack 13, and the electrode clamp mounting plate 1 and the Y-direction horizontal adjustment rack 13 are connected and fixed by a second vertical screw 27.

[0029] To ensure greater overall reliability after the X-axis horizontal position is adjusted, in some preferred embodiments, the movable end of the X-axis horizontal adjustment rack 8 is equipped with a first lateral locking mechanism. The first lateral locking mechanism is used to apply a clamping force in the left and right directions to the X-axis horizontal adjustment rack 8. The first lateral locking mechanism includes a first lateral locking block 18 and a first limiting steel ball 19 respectively disposed on both sides of the movable end of the X-axis horizontal adjustment rack 8. The first lateral locking block 18 is installed on the second horizontal adjustment mounting block 4 by a first lateral locking adjusting bolt 20. The first lateral locking block 18 is slidably disposed in the locking block mounting groove at the upper end of the second horizontal adjustment mounting block 4 in the left and right directions. The axis of the first lateral locking adjusting bolt 20 extends in the left and right directions. The tail end of the first lateral locking adjusting bolt 20 passes through the mating hole on the second horizontal adjustment mounting block 4 and forms a threaded connection with the first lateral locking block 18. In practice, to make the layout more compact, the X-axis horizontal adjustment hinge shaft 6 and the X-axis horizontal adjustment gear rack mechanism are usually arranged in a relative manner. For example, in the preferred embodiment shown in the figure, the X-axis horizontal adjustment hinge shaft 6 is designed on the front and rear sides of the left end of the second horizontal adjustment mounting block 4, while the X-axis horizontal adjustment gear rack mechanism is designed in the right end area of ​​the second horizontal adjustment mounting block 4 (and is set as centrally as possible in the front and rear direction). For ease of assembly, in the preferred embodiment described above, the first limiting steel ball 19 is positioned on the right side of the X-axis horizontal adjusting rack 8, and the first lateral locking block 18 is positioned on the left side of the X-axis horizontal adjusting rack 8 (the local structure where the pressing working surface is located can be located on the left side of the X-axis horizontal adjusting rack 8). When the first lateral locking adjusting bolt 20 is rotated, the first lateral locking block 18 can slide in the locking block mounting groove in the left and right directions. When the first lateral locking block 18 moves to the right, it can press and fix the X-axis horizontal adjusting rack 8 (at this time, X-axis horizontal adjustment cannot be performed by rotating the X-axis horizontal adjusting worm 10). When the first lateral locking block 18 moves to the left, it releases the X-axis horizontal adjusting rack 8 without affecting the normal operation of the X-axis horizontal adjusting gear rack structure. That is, when X-axis horizontal position adjustment is required, the first lateral locking adjusting bolt 20 should be loosened in advance; after the X-axis horizontal position adjustment is completed, the first lateral locking adjusting bolt 20 should be tightened again.

[0030] To facilitate assembly and make the locking structure more reliable, in some preferred embodiments, the second horizontal adjustment mounting block 4 is provided with a first limiting steel ball mounting hole for mounting the first limiting steel ball 19. The inner end of the first limiting steel ball mounting hole is provided with a first limiting flange that limits the side of the first limiting steel ball 19 facing the X-direction horizontal adjustment rack 8. A first steel ball limiting adjustment bolt 21 is provided on the side of the first limiting steel ball 19 away from the X-direction horizontal adjustment rack 8. The axis of the first steel ball limiting adjustment bolt 21 extends in the left and right direction. The first steel ball limiting adjustment bolt 21 is threadedly connected to the first limiting steel ball mounting hole. The inner end of the first steel ball limiting adjustment bolt 21 is used to limit the first limiting steel ball 19. By adjusting the connection position of the first steel ball limiting adjusting bolt 21 within the mounting hole of the first limiting steel ball, the clearance between the first limiting steel ball 19 and the X-direction horizontal adjusting rack 8 can also be adjusted. This ensures that when the first lateral locking adjusting bolt 20 is tightened, both the first lateral locking block 18 and the first limiting steel ball 19 can make tight contact with the mating surface on the X-direction horizontal adjusting rack 8, thereby pressing and fixing the X-direction horizontal adjusting rack 8. To further improve structural reliability, multiple first limiting steel balls 19 are preferably arranged at vertical intervals, with each first steel ball limiting adjusting bolt 21 corresponding to a different first limiting steel ball 19. In the preferred embodiment shown in the figure, two first limiting steel balls 19 arranged at vertical intervals are used.

[0031] Similarly, to ensure greater reliability of the overall structure after the Y-axis horizontal position is adjusted, in some preferred embodiments, the movable end of the Y-axis horizontal adjustment rack 13 is equipped with a second lateral locking mechanism. The second lateral locking mechanism is used to apply a clamping force in the front-back direction to the Y-axis horizontal adjustment rack 13. The second lateral locking mechanism includes a second lateral locking block 22 and a second limiting steel ball 23 respectively disposed on both sides of the movable end of the Y-axis horizontal adjustment rack 13. The second lateral locking block 22 is installed on the second horizontal adjustment mounting block 4 by a second lateral locking adjusting bolt 24. The second lateral locking block 22 is slidably disposed in the locking block mounting groove at the lower end of the second horizontal adjustment mounting block 4 in the front-back direction. The axis of the second lateral locking adjusting bolt 24 extends in the front-back direction. The tail end of the second lateral locking adjusting bolt 24 passes through the mating hole on the second horizontal adjustment mounting block 4 and forms a threaded connection with the second lateral locking block 22. In practice, to make the layout more compact, the Y-axis horizontal adjustment hinge shaft 11 and the Y-axis horizontal adjustment gear rack mechanism are usually arranged in a relative manner. For example, in the preferred embodiment shown in the figure, the Y-axis horizontal adjustment hinge shaft 11 is designed on the left and right sides of the rear end of the second horizontal adjustment mounting block 4, while the Y-axis horizontal adjustment gear rack mechanism is designed in the front end area of ​​the second horizontal adjustment mounting block 4 (and is set as centrally as possible in the left and right direction). For ease of assembly, in the preferred embodiment described above, the second limiting steel ball 23 is positioned on the front side of the Y-axis horizontal adjusting rack 13, and the second lateral locking block 22 is positioned on the rear side of the Y-axis horizontal adjusting rack 13 (the local structure where the pressing working surface is located can be positioned on the rear side of the Y-axis horizontal adjusting rack 13). When the second lateral locking adjusting bolt 24 is rotated, the second lateral locking block 22 can slide in the locking block mounting groove along the front-back direction. When the second lateral locking block 22 moves forward, it can press and fix the Y-axis horizontal adjusting rack 13 (at this time, Y-axis horizontal adjustment cannot be performed by rotating the Y-axis horizontal adjusting worm 15). When the second lateral locking block 22 moves backward, it releases the Y-axis horizontal adjusting rack 13, without affecting the normal operation of the Y-axis horizontal adjusting gear rack structure. In other words, when Y-axis horizontal position adjustment is required, the second lateral locking adjusting bolt 24 must be loosened beforehand; after Y-axis horizontal position adjustment is completed, the second lateral locking adjusting bolt 24 can be retightened.

[0032] To facilitate assembly and make the locking structure more reliable, in some preferred embodiments, the second horizontal adjustment mounting block 4 is provided with a second limiting steel ball mounting hole for mounting the second limiting steel ball 23. The inner end of the second limiting steel ball mounting hole is provided with a second limiting flange that limits the side of the second limiting steel ball 23 facing the Y-direction horizontal adjustment rack 13. A second steel ball limiting adjustment bolt 25 is provided on the side of the second limiting steel ball 23 away from the Y-direction horizontal adjustment rack 13. The axis of the second steel ball limiting adjustment bolt 25 extends along the front-back direction. The second steel ball limiting adjustment bolt 25 is threadedly connected to the second limiting steel ball mounting hole. The inner end of the second steel ball limiting adjustment bolt 25 is used to limit the second limiting steel ball 23. By adjusting the connection position of the second steel ball limiting adjusting bolt 25 within the mounting hole of the second limiting steel ball, the clearance between the second limiting steel ball 23 and the Y-direction horizontal adjusting rack 13 can also be adjusted. This ensures that when the second lateral locking adjusting bolt 24 is tightened, both the second lateral locking block 22 and the second limiting steel ball 23 can make tight contact with the mating surface on the Y-direction horizontal adjusting rack 13, thereby pressing and fixing the Y-direction horizontal adjusting rack 13. To further improve structural reliability, multiple second limiting steel balls 23 are preferably arranged at vertical intervals, with each second steel ball limiting adjusting bolt 25 corresponding to a different second limiting steel ball 23. In the preferred embodiment shown in the figure, two second limiting steel balls 23 arranged at vertical intervals are used.

[0033] To facilitate assembly and ensure a simple and reliable structure, in some preferred embodiments, the outer end of the X-direction horizontal adjusting worm 10 is detachably connected and coaxially provided with an X-direction horizontal adjusting worm drive rod 28. The inner end of the integral component consisting of the X-direction horizontal adjusting worm 10 and the X-direction horizontal adjusting worm drive rod 28 is axially limited by the inner wall of the mounting hole on the second horizontal adjusting mounting block 4, and the outer end is axially limited by the first limiting sleeve 29 provided on the second horizontal adjusting mounting block 4. The outer end of the Y-direction horizontal adjusting worm 15 is detachably connected and coaxially provided with a Y-direction horizontal adjusting worm drive rod 30. The inner end of the integral component consisting of the Y-direction horizontal adjusting worm 15 and the Y-direction horizontal adjusting worm drive rod 30 is axially limited by the inner wall of the mounting hole on the second horizontal adjusting mounting block 4, and the outer end is axially limited by the second limiting sleeve 31 provided on the second horizontal adjusting mounting block 4. Rotation tool interfaces are respectively provided at the outer ends of the X-direction horizontal adjusting worm drive rod 28 and the Y-direction horizontal adjusting worm drive rod 30. The first limiting sleeve 29 and the second limiting sleeve 31 can generally be fixed in the designed position using a threaded connection structure. This means that the first limiting sleeve 29 and the second limiting sleeve 31 each have an external thread structure, and the inner wall of the mounting hole on the second horizontal adjustment mounting block 4 has a corresponding internal thread structure. Since detachable X-axis horizontal adjustment worm gear drive rod 28 and Y-axis horizontal adjustment worm gear drive rod 30 are provided, when the rotating tool interface is damaged, only the X-axis horizontal adjustment worm gear drive rod 28 and the Y-axis horizontal adjustment worm gear drive rod 30 need to be replaced. The X-axis horizontal adjustment worm 10 and the X-axis horizontal adjustment worm gear drive rod 28 are typically connected by a non-circular connecting shaft (e.g., a regular hexagonal or square connecting shaft) engaging with the positioning hole; the Y-axis horizontal adjustment worm 15 and the Y-axis horizontal adjustment worm gear drive rod 30 are typically connected by a non-circular connecting shaft (e.g., a regular hexagonal or square connecting shaft) engaging with the positioning hole.

[0034] To make the Z-axis rotation adjustment structure more reliable, easier to process and assemble, and more convenient for adjustment, in some preferred embodiments, the vertical central shaft 5 is a Z-axis adjustment locking bolt. The tail end of the Z-axis adjustment locking bolt passes through the mating hole on the first horizontal adjustment mounting block 2 and the mating hole on the rotation adjustment support 3 from bottom to top, and is then connected to the Z-axis adjustment locking nut 32. The mating hole on the rotation adjustment support 3 through which the Z-axis adjustment 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 upper surface of the rotation adjustment support 3, and the inner diameter of the first stepped hole is larger than the inner diameter of the second stepped hole. The second stepped hole is coaxially fixedly installed. The system includes a Z-axis adjusting bearing 33, which forms a rotational fit between the inner circumferential wall of the second stepped hole and the outer wall of the Z-axis adjusting locking bolt. A Z-axis adjusting locking nut 32 is disposed within the first stepped hole, and its lower end face forms a rotational fit between the lower end face of the Z-axis adjusting locking nut 32 and the inner bottom wall of the first stepped hole via a Z-axis adjusting first support ball 34. A rotational fit between the lower surface of the rotary adjusting support seat 3 and the upper surface of the first horizontal adjusting mounting block 2 is formed by a Z-axis adjusting second support ball 35. Both the Z-axis adjusting first support ball 34 and the Z-axis adjusting second support ball 35 are arranged in a ring around the vertical central axis 5. The Z-axis rotary adjusting structure also includes a Z-axis adjusting limit screw 36. Z-axis adjusting limit post 37, Z-axis adjusting force post 38, and Z-axis adjusting screw nut moving pair are provided. Z-axis adjusting limit post 37 and Z-axis adjusting force post 38 are located on one side of the vertical central axis 5, and the axes of the three are parallel. The upper surface of the first horizontal adjusting mounting block 2 is provided with a Z-axis adjusting component movable hole 39. The upper ends of Z-axis adjusting limit post 37 and Z-axis adjusting force post 38 are respectively fixedly connected to the rotary adjusting support 3. The lower ends of Z-axis adjusting limit post 37 and Z-axis adjusting force post 38 are correspondingly inserted into the Z-axis adjusting component movable hole 39. Z-axis adjusting limit screw 36 is threadedly connected to two oppositely arranged side walls of the Z-axis adjusting component movable hole 39. The inner end of the screw 36 is used to limit the Z-direction adjustment limit post 37; the Z-direction adjustment screw and nut moving pair includes a Z-direction adjustment screw 40 and a Z-direction adjustment nut 41. The Z-direction adjustment screw 40 is rotatably mounted on the first horizontal adjustment mounting block 2 in the horizontal direction. The outer end of the Z-direction adjustment screw 40 is provided with a rotating tool interface (preferably in the form of an internal hexagonal interface). The lower end of the Z-direction adjustment force post 38 is nested in the actuating groove on the Z-direction adjustment nut 41. The reciprocating movement of the Z-direction adjustment nut 41 along the Z-direction adjustment screw 40 can drive the Z-direction adjustment force post 38 to move, thereby causing the first horizontal adjustment mounting block 2 and the rotary adjustment support 3 to rotate relative to each other around the vertical central axis 5. The inner end of the Z-direction adjustment limit screw 36 preferably adopts a spherical arc surface structure design.

[0035] The function of the Z-axis adjusting member movable hole 39 is to allow the first horizontal adjusting mounting block 2 and the rotary adjusting support 3 to rotate relative to each other within a certain angle range around the vertical central axis 5. The lower end of the Z-axis adjusting limit post 37, the lower end of the Z-axis adjusting force post 38, and the Z-axis adjusting nut 41 can all move correspondingly within the Z-axis adjusting member movable hole 39. In specific implementation, when the inner ends of the two Z-axis adjusting limit screws 36 are locked against the outer circumference of the Z-axis adjusting force post 38, the first horizontal adjusting mounting block 2 and the rotary adjusting support 3 cannot rotate relative to each other around the vertical central axis 5. When the Z-axis adjusting limit screws 36 are loosened, the first horizontal adjusting mounting block 2 and the rotary adjusting support 3 can rotate relative to each other around the vertical central axis 5. When Z-axis rotation adjustment is required, loosen the Z-axis adjustment limit screw 36 beforehand, and then use a wrench to rotate the Z-axis adjustment screw 40. This will cause the Z-axis adjustment force column 38 to move through the Z-axis adjustment nut 41, thereby causing the first horizontal adjustment mounting block 2 and the rotation adjustment support 3 to rotate relative to each other around the vertical central axis 5. After adjustment, tighten the Z-axis adjustment limit screw 36 again.

[0036] For ease of assembly and operation, the Z-axis adjusting screw 40 is coaxially engaged with the Z-axis adjusting screw drive rod 67. The two are typically connected by a non-circular connecting shaft (e.g., a hexagonal or square connecting shaft) engaging with a positioning locking hole. The ends of the Z-axis adjusting screw 40 and the Z-axis adjusting screw drive rod 67 furthest from each other can be axially limited by a third limiting sleeve 68 and a fourth limiting sleeve 69, respectively. The third limiting sleeve 68 and the fourth limiting sleeve 69 are fixed in their designed positions using a threaded connection structure. The ends of the Z-axis adjusting screw 40 and the Z-axis adjusting screw drive rod 67 furthest from each other are each provided with a rotating tool interface, allowing for the connection of a wrench tool at either location. In some embodiments, a radial partition plate can also be provided in the mounting holes of the Z-axis adjusting screw 40 and the Z-axis adjusting screw drive rod 67, with a third preload disc spring 66 positioned between the radial partition plate and the inner end face of the Z-axis adjusting screw 40.

[0037] To facilitate control over the accuracy of Z-axis rotational adjustment, in some preferred embodiments, the outer peripheral surface of the rotational adjustment support 3 and the outer peripheral surface of the first horizontal adjustment mounting block 2 are provided with mutually cooperating angle indicator marks and angle scales at their contact points. Essentially, one component of the rotational adjustment support 3 and the first horizontal adjustment mounting block 2 is used to set the angle indicator marks, and the other component 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 rotational adjustment structure can be visually observed.

[0038] To facilitate XY-axis center adjustment during electrode calibration, in some preferred embodiments, an XY-axis center adjustment mechanism is mounted on the upper surface of the rotary adjustment support 3. This mechanism includes an X-axis center adjustment block 42, a center adjustment cross slider 43, and a Y-axis center adjustment block 44 arranged sequentially from bottom to top. The lower surface of the X-axis center adjustment block 42 is fixedly connected to the upper surface of the rotary adjustment support 3. The X-axis center adjustment block 42 and the X-axis center adjustment block 44 are generally connected and fixed by a third vertical screw 61. The upper surface of the X-axis center adjustment block 42... The center adjusting cross slider 43 is connected to the center adjusting cross slider 43 via an X-direction screw and nut sliding pair, allowing the center adjusting cross slider 43 to move relative to the X-direction center adjusting block 42 in the left and right directions. The X-direction screw and nut sliding pair includes an X-direction center adjusting screw 45, an X-direction center adjusting nut 46, and an X-direction sliding pair. The X-direction sliding pair consists of a mating X-direction slider 47 and an X-direction slide groove. One side wall of the X-direction slide groove is inclined, and the other side wall is vertical, such that the groove opening width is smaller than the groove bottom width. The vertical side wall of the X-direction slide groove... An X-axis center adjustment locking mechanism is installed on this side. This mechanism includes an X-axis center adjustment locking bolt 48, an X-axis center adjustment pad 49, an X-axis center adjustment preload bolt 50, an X-axis center adjustment preload block 51, and a first preload disc spring 52. The axes of the X-axis center adjustment locking bolt 48 and the X-axis center adjustment preload bolt 50 are both perpendicular to the length direction of the X-axis slide groove. The X-axis center adjustment locking bolt 48 is threaded to the side wall of the X-axis slide groove, and the X-axis center adjustment pad 49 is disposed on the X-axis center adjustment locking bolt 48. Between the inner end face of the X-axis center adjusting preload bolt 50 and the side surface of the X-axis slider 47, the inner end of the X-axis center adjusting preload bolt 50 passes through the mating hole on the side wall of the X-axis slide groove and is threadedly connected to the X-axis center adjusting preload block 51; the first preload disc spring 52 is sleeved on the outer periphery of the X-axis center adjusting preload bolt 50 and is located between the X-axis center adjusting preload block 51 and the side wall of the X-axis slide groove. The side wall of the X-axis slide groove can generally be provided with a stepped mating hole that matches the X-axis center adjusting preload block 51. The side of the X-axis center adjusting preload block 51 away from the first preload disc spring 52 is used to abut against the X-axis slider 47.The lower surface of the Y-direction center adjusting block 44 is connected to the center adjusting cross slider 43 via a Y-direction screw and nut moving pair, allowing the center adjusting cross slider 43 to move relative to the Y-direction center adjusting block 44 in the front-back direction. The Y-direction screw and nut moving pair includes a Y-direction center adjusting screw 53, a Y-direction center adjusting nut 54, and a Y-direction sliding pair. The Y-direction sliding pair consists of a mating Y-direction slider 55 and a Y-direction sliding groove. One side wall of the Y-direction sliding groove is inclined, and the other side wall is vertical, such that the groove opening width is smaller than the groove bottom width. A Y-direction center adjusting locking mechanism is installed on the vertical side wall of the Y-direction sliding groove. The Y-direction center adjusting locking mechanism includes a Y-direction center adjusting locking bolt 56, a Y-direction center adjusting pad 57, a Y-direction center adjusting pre-tightening bolt 58, a Y-direction center adjusting pre-tightening block 59, and a second pre-tightening disc spring 60. The axis of the Y-direction center adjusting locking bolt 56 and the Y-direction center adjusting pre-tightening block 60 are connected. The axes of bolts 58 are perpendicular to the length direction of the Y-direction slide. The Y-direction center adjusting locking bolt 56 is threaded onto the side wall of the Y-direction slide. The Y-direction center adjusting pad 57 is positioned between the inner end face of the Y-direction center adjusting locking bolt 56 and the side surface of the Y-direction slider 55. The inner end of the Y-direction center adjusting pre-tightening bolt 58 passes through a mating hole on the side wall of the Y-direction slide and is threaded onto the Y-direction center adjusting pre-tightening block 59. The second pre-tightening disc spring 60 is sleeved on the outer periphery of the Y-direction center adjusting pre-tightening bolt 58 and positioned between the Y-direction center adjusting pre-tightening block 59 and the side wall of the Y-direction slide. The side wall of the Y-direction slide can generally be provided with a stepped mating hole adapted to the Y-direction center adjusting pre-tightening block 59. The side of the Y-direction center adjusting pre-tightening block 59 away from the second pre-tightening disc spring 60 is used to abut against the Y-direction slider 55. Rotating tool interfaces (preferably internal hexagonal interfaces) are respectively provided at the outer ends of the X-direction center adjusting screw 45 and the Y-direction center adjusting screw 53.

[0039] During assembly, the preload force applied to the X-axis slider 47 by the first preload disc spring 52 can be adjusted by adjusting the relative connection positions of the X-axis center adjusting preload bolt 50 and the X-axis center adjusting preload block 51. The main function of the X-axis center adjusting preload bolt 50, the X-axis center adjusting preload block 51, and the first preload disc spring 52 is to eliminate the fit clearance between the X-axis slider 47 and the X-axis slide groove, thereby improving the sliding adjustment accuracy. Similarly, the preload force applied to the Y-axis slider 55 by the second preload disc spring 60 can be adjusted by adjusting the relative connection positions of the Y-axis center adjusting preload bolt 58 and the Y-axis center adjusting preload block 59.

[0040] For ease of processing and assembly, both the X-axis slider 47 and the Y-axis slider 55 can be integrated onto the center adjustment cross slider 43 (preferably designed as a single unit). The X-axis center adjustment screw 45 and the Y-axis center adjustment screw 53 are rotatably mounted on the center adjustment cross slider 43. The X-axis center adjustment nut 46 is fixed to the X-axis center adjustment block 42, and the Y-axis center adjustment nut 54 is fixed to the Y-axis center adjustment block 44. In some alternative embodiments, the X-axis slider 47 and the X-axis slide can be interchanged. In other alternative embodiments, the Y-axis slider 55 and the Y-axis slide can be interchanged. In some alternative embodiments, the X-axis center adjustment screw 45 and the X-axis center adjustment nut 46 can be interchanged. In some alternative embodiments, the Y-axis center adjustment screw 53 and the Y-axis center adjustment nut 54 can be interchanged. More specifically, the X-direction center adjusting nut 46 can generally be fixedly installed by a combination of the X-direction center adjusting nut positioning seat 62 and the X-direction center adjusting nut positioning plug 63; the Y-direction center adjusting nut 54 can be fixedly installed by a combination of the Y-direction center adjusting nut positioning seat 64 and the Y-direction center adjusting nut positioning plug 65.

[0041] To ensure a simple, reliable, and easy-to-operate structure, the X-axis center adjusting screw 45 is coaxially engaged with the X-axis screw connecting rod 72. The two are typically connected by a non-circular connecting shaft (e.g., a hexagonal or square connecting shaft) that engages with a positioning locking hole. The ends of the X-axis center adjusting screw 45 and the X-axis screw connecting rod 72 furthest from each other can be axially limited by X-axis screw fixing limit sleeves 74, which are fixed in the designed position using a threaded connection. Both ends of the X-axis center adjusting screw 45 and the X-axis screw connecting rod 72 have rotating tool interfaces, allowing for the connection of wrenches at either location.

[0042] Similarly, the Y-axis center adjusting screw 53 is coaxially engaged with the Y-axis screw connecting rod 73. The two are typically connected by a non-circular connecting shaft (e.g., a hexagonal or square connecting shaft) that engages with the positioning locking hole. The ends of the Y-axis center adjusting screw 53 and the Y-axis screw connecting rod 73 furthest from each other can be axially limited by the Y-axis screw fixing limiting sleeve 75, which is fixed in the designed position using a threaded connection structure. The ends of the Y-axis center adjusting screw 53 and the Y-axis screw connecting rod 73 furthest from each other are each provided with a rotating tool interface, allowing for the connection of wrenches at both locations.

[0043] Multiple X-axis center adjusting locking bolts 48 are generally arranged at intervals along the length of the X-axis slide groove. The embodiment shown in the figure has two X-axis center adjusting locking bolts 48. The X-axis center adjusting locking bolts 48 are used to fix the relative position of the X-axis slider 47 and the X-axis slide groove. When X-axis center adjustment is required, the X-axis center adjusting locking bolts 48 need to be loosened beforehand. After adjustment, the X-axis center adjusting locking bolts 48 are tightened again. Multiple Y-axis center adjusting locking bolts 56 are generally arranged at intervals along the length of the Y-axis slide groove. The embodiment shown in the figure has two Y-axis center adjusting locking bolts 56. The Y-axis center adjusting locking bolts 56 are used to fix the relative position of the Y-axis slider 55 and the Y-axis slide groove. When Y-axis center adjustment is required, the Y-axis center adjusting locking bolts 56 need to be loosened beforehand. After adjustment, the Y-axis center adjusting locking bolts 56 are tightened again.

[0044] The Y-axis center adjustment block 44 is the positioning plate fixing block, which is usually provided with positioning mounting screw holes 71 for connecting and fixing the object. During the adjustment operation, after loosening the X-axis center adjustment locking bolt 48 and the Y-axis center adjustment locking bolt 56, the X-axis center adjustment screw 45 and the Y-axis center adjustment screw 53 are rotated using a wrench. This allows the electrode installation position to move horizontally left and right and forward and backward, 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 X-axis center adjustment locking bolt 48 and the Y-axis center adjustment locking bolt 56 can be tightened again.
