Description

A multi-head structure for an EDM machine and a machine tool Technical Field

[0001] This application relates to the field of machine tool component technology, and in particular to a multi-head structure and machine tool for an EDM machine. Background Technology

[0002] In the fields of modern industrial automation and precision machining, with the continuous improvement of production efficiency and machining accuracy requirements, traditional machining equipment can no longer meet the complex and ever-changing machining needs.

[0003] Currently, machining equipment typically uses a single moving module, such as an X-axis, Y-axis, or Z-axis moving module, to move or process the workpiece in a single dimension. When dealing with machining tasks that require simultaneous or alternating operations in multiple dimensions, this structure often needs to process different parts of the workpiece simultaneously or sequentially. However, a single-head structure often requires multiple repositioning and relocation to complete this task. This not only increases the machining time but may also affect the machining accuracy due to errors introduced by multiple positioning. Furthermore, traditional single moving modules are fixed to the corresponding machine tool and cannot be integrated, resulting in poor flexibility.

[0044] Please refer to Figures 1 to 6. This application provides a multi-head structure for an EDM machine, including: an X-axis linear module 1, a Y-axis moving component, a Z-axis moving component, and an EDM head 5; the X-axis linear module 1 includes an auxiliary base 11 and an X-axis moving component 12, at least two of the X-axis moving components 12 are mounted on the auxiliary base 11, and the X-axis moving components 12 are used to move left and right on the auxiliary base 11; the Y-axis moving component is mounted on the X-axis moving component 12, and the Y-axis moving component is used to move back and forth on the X-axis moving component 12; the Z-axis moving component is mounted on the Y-axis moving component, and the Z-axis moving component is used to move up and down on the Y-axis moving component; the EDM head 5 is mounted on the Z-axis moving component.

[0045] First, let's explain the function of each component:

[0046] Auxiliary base 11: As the basic support platform of the entire multi-head structure, it provides a stable mounting base for other components, ensuring the stability and accuracy of the entire multi-head structure during operation, and bearing the weight and force generated by the movement of the components above.

[0047] X-axis moving parts 12: Two X-axis moving parts 12 are mounted on the auxiliary base 11 and can move along the X-axis direction, that is, the left and right direction. By moving left and right, the lateral position of the Y-axis moving parts and all the parts mounted on them on the horizontal plane can be adjusted, so as to realize the flexible adjustment of the processing position.

[0048] Y-axis moving component: Installed on X-axis moving component 12, it can move along the Y-axis direction, that is, the back-and-forth direction. In conjunction with X-axis moving component 12, it can achieve precise positioning of the machining position on the horizontal plane, increasing the flexibility and range of machining.

[0049] Z-axis moving component: Installed on the Y-axis moving component, it can move along the Z-axis direction, that is, the up and down direction. By moving up and down, the height of the EDM head 5 can be adjusted to achieve precise control of the machining depth or machining height, so as to meet different machining needs.

[0050] Electrical discharge machining head 5: Mounted on the Z-axis moving part, it is the execution part for performing machining tasks. It can perform precise machining on the workpiece through electrical discharge machining according to the machining requirements, such as drilling, cutting, engraving, etc.

[0051] Overall equipment working principle:

[0052] This multi-head structure achieves precise three-dimensional positioning and movement of the EDM head 5 in space through the coordinated operation of three-axis moving components.

[0053] Initial positioning: First, according to the requirements of the machining task, the EDM head 5 is moved to the horizontal coordinate point of the machining position by controlling the X-axis moving part 12 and the Y-axis moving part.

[0054] Height Adjustment: Next, the height of the EDM head 5 is adjusted by the Z-axis moving component to ensure that its relative position with the workpiece meets the processing requirements.

[0055] Processing execution: After precise positioning, the EDM head 5 starts working and performs EDM on the workpiece according to the preset processing parameters and program.

[0056] Processing complete: After processing is completed, each moving part returns to its initial position or prepares for the next processing position according to the instructions.

[0057] In this way, the multi-head structure enables efficient and precise electrical discharge machining, suitable for various applications requiring high-precision processing. At the same time, its compact structure and flexible movement also improve the convenience and efficiency of machining.

[0058] Furthermore, since all the aforementioned components are integrated into the X-axis moving module, modular assembly is achieved, thereby enabling the integration of the X-axis moving module with other machine tools and improving the flexibility of the equipment.

[0059] Optionally, the X-axis moving component 12, the Y-axis moving component, and the Z-axis moving component are independent of each other.

[0060] In this embodiment, the X-axis moving component 12, the Y-axis moving component, and the Z-axis moving component are responsible for movement in different directions. The X-axis moving component 12 is used for left and right movement, the Y-axis moving component is used for forward and backward movement, and the Z-axis moving component is used for up and down movement. By setting the X-axis moving component 12, the Y-axis moving component, and the Z-axis moving component to work independently, it can be ensured that each component can be used for its specific direction of movement. Moreover, their independence allows each component to be precisely adjusted according to processing requirements without interfering with each other, thus improving the flexibility and efficiency of processing.

[0061] Optionally, the auxiliary base 11 is provided with a guide rail base, a track body and a guide groove. The guide rail base is provided on both sides of the outer side of the auxiliary base 11, and the track body is fixed on the guide rail base. The track body is provided with the guide groove, and the length of the guide groove is adapted to the length of the track body.

[0062] In this embodiment, the guide rail base is disposed on the auxiliary base 11 and located on both sides of the outer side of the auxiliary base 11. The track body is fixed on the auxiliary base 11. The guide rail base supports the track body and provides a stable mounting base for it. The track body is fixed on the guide rail base and has sufficient strength and rigidity to withstand the weight and force generated by the movement of the X-axis moving component 12 and the mounted components thereon, so that the X-axis moving component 12 can move on the track body.

[0063] The track body is fixed by bolt or welding to ensure that it will not loosen or fall off during use.

[0064] The guide groove is arranged along the length of the track body. The main function of the guide groove is to guide the X-axis moving component 12 to move smoothly and accurately on the track body. The length of the guide groove is adapted to the length of the track body, that is, the guide groove can cover the entire length range of the track body, thereby ensuring that the X-axis moving component 12 can be effectively guided and supported at any position.

[0065] By setting up a guide rail base, a rail body, and a guide groove, a stable and reliable guide rail system can be formed on the auxiliary base 11, providing precise guidance for the X-axis moving component 12.

[0066] Optionally, the X-axis moving component 12 includes an X-axis slide and a guide block; the X-axis slide is movably mounted on the track body; the guide block is mounted on the X-axis slide and is placed in the guide groove, the guide block cooperating with the guide groove to enable the X-axis moving component 12 to move along the track body on the auxiliary base 11.

[0067] In this embodiment, the X-axis slide is the main component of the X-axis moving part 12. The X-axis slide is movably mounted on the track body and can be achieved by means of pulleys, sliders or rollers to ensure that the X-axis slide can move smoothly and steadily along the track body.

[0068] The guide block is mounted on the X-axis slide and its function is to ensure that the X-axis moving component 12 maintains the correct orientation and position during movement. The guide block cooperates with the guide groove. When the X-axis slide moves, the guide block moves along the guide groove, thereby ensuring that the movement trajectory of the X-axis moving component 12 is consistent with the direction of the track body. This cooperation not only improves the movement accuracy of the X-axis moving component 12, but also reduces friction and wear during movement, extending the service life of the component.

[0069] When the X-axis moving component 12 needs to be moved, a force is applied to the X-axis slide block through the drive mechanism, causing it to move along the track body. During the movement, the guide block moves along the guide groove to ensure that the movement trajectory of the X-axis moving component 12 is correct and stable. By controlling the output of the drive mechanism, the precise movement and positioning of the X-axis moving component 12 can be achieved.

[0070] Optionally, the Y-axis moving component includes a Y-axis fixed seat 2 and a Y-axis slide 3, wherein the Y-axis fixed seat 2 is mounted on the X-axis slide 3; and the Y-axis slide 3 is movably mounted on the Y-axis fixed seat 2.

[0071] In this embodiment, the Y-axis moving component consists of two parts: a Y-axis fixed base 2 and a Y-axis slide 3. The Y-axis moving component enables movement in the Y-axis direction, i.e., the forward and backward direction.

[0072] Specifically, the Y-axis mounting base 2 is a support structure for the Y-axis moving component. The Y-axis mounting base 2 is installed on the X-axis slide block, thereby ensuring that the Y-axis moving component can remain stable when moving along the X-axis and will not shake or deviate due to the movement of the X-axis.

[0073] The Y-axis slide 3 is the part responsible for the actual movement of the Y-axis moving component. It is movably mounted on the Y-axis fixed base 2 and can be moved by mechanisms such as pulleys, sliders, guide rails, or rollers, without specific limitations. The movable mounting method allows the Y-axis slide 3 to move smoothly and steadily along the Y-axis direction on the Y-axis fixed base 2, thereby realizing the forward and backward movement of the Y-axis moving component.

[0074] When the Y-axis moving component needs to be moved, the drive mechanism applies force to the Y-axis slide 3, causing it to move back and forth along the Y-axis fixed seat 2. Since the Y-axis fixed seat 2 is stably installed on the X-axis slide, the movement of the Y-axis moving component is not affected by the movement of the X-axis, ensuring the accuracy and stability of the movement.

[0075] Optionally, one end of the Y-axis slide block 3 is provided with a receiving slot, and the Z-axis moving component is movably installed in the receiving slot. Guide rail grooves are provided on both sides inside the receiving slot, and guide rails are installed inside the guide rail grooves. The Z-axis moving component includes a Z-axis fixed seat 4 and a guide rail module 6. The guide rail module 6 is installed on the outside of the Z-axis fixed seat 4, and the Z-axis fixed seat 4 is movably installed in the guide rail through the guide rail module 6.

[0076] In this embodiment, one end of the Y-axis slide block 3 is provided with a receiving slot, which is provided for mounting and supporting the Z-axis moving component. By providing the receiving slot, it can be ensured that the Z-axis moving component can move stably and smoothly within it.

[0077] Specifically, guide rail grooves are provided on both sides of the inner cavity of the cavity, and guide rails are installed in the guide rail grooves. The shape and size of the guide rail grooves match the guide rails. The guide rails cooperate with the guide rail grooves to guide the Z-axis moving parts to move precisely up and down in the cavity.

[0078] The Z-axis moving component consists of two parts: the Z-axis fixed base 4 and the guide rail module 6. The Z-axis fixed base 4 is the main structure of the Z-axis moving component, bearing other components and loads. The guide rail module 6 is installed on both sides of the Z-axis fixed base 4. The guide rail module 6 cooperates with the guide rail to realize the movable installation of the Z-axis fixed base 4 on the guide rail.

[0079] Optionally, the EDM head 5 can be detachably mounted on the Z-axis mounting base 4.

[0080] In this embodiment, the electrical discharge machining head 5 is a component for performing electrical discharge machining. The electrical discharge machining head 5 is detachably mounted on the Z-axis mounting base 4, and can be easily disassembled and replaced according to machining or maintenance needs.

[0081] Detachable installation is typically achieved through bolted or snap-fit ​​connections, which are not specifically limited here. These connection methods ensure the stability and safety of the EDM head 5 during processing, while also facilitating disassembly and installation by the user.

[0082] Specifically, when installing the EDM head 5, the Z-axis mounting base 4 needs to be moved to the appropriate position and ensured to remain stable. Then, the EDM head 5 is aligned with the mounting interface on the Z-axis mounting base 4 and fixed using a suitable connection method.

[0083] When disassembling the EDM head 5, the user needs to first loosen the connecting mechanism and then remove the EDM head 5 from the Z-axis mounting base 4.

[0084] By setting it to a detachable connection method, different models or specifications of EDM head 5 can be easily replaced to meet different processing needs. It also makes it easier for users to maintain and care for EDM head 5, extending its service life.

[0085] Optionally, an assembly assembly is connected to the auxiliary base 11, and the assembly assembly, in conjunction with the connector, is used to assemble the auxiliary double-head structure onto the machine tool.

[0086] In this embodiment, the assembly component is a part that connects the auxiliary base 11 and the machine tool. The function of the assembly component is to provide a stable connection point, ensuring that the auxiliary double-head structure can be firmly installed on the machine tool without shaking or shifting during processing, thus meeting the requirements for precise processing and efficient assembly and improving the flexibility of the equipment.
