Description

TECHNICAL FIELD

[0001] The application relates to the technical field of machine tool structures, in particular to a machine tool structure of a symmetrical combined head. BACKGROUND

[0002] Electrical discharge machining (EDM) is an advanced machining method that precisely removes conductive materials through an electrical discharge process, suitable for high-hardness materials and complex shape machining. In traditional EDM equipment, single-head or double-head machine tools are usually used for machining. Machine tools of this structure can generally meet the machining needs of small-sized workpieces or simple-shaped molds, and are suitable for some small and medium batch machining tasks. However, with the development of industrial production, the demand for complex molds has increased dramatically, especially in the field of large-scale, diversified and high-precision mold manufacturing, which puts forward higher requirements on the machining range, efficiency and flexibility of EDM equipment. Modern industry often involves fine machining of multiple areas of complex workpieces. If only relying on traditional single-head or double-head equipment for multiple clamping and machining, not only will the machining time be significantly prolonged, but also the error accumulation in the clamping and positioning process will be increased, affecting the machining precision.

[0003] In the prior art, the emergence of multi-head EDM machine tools has partially solved this problem. By increasing multiple EDM heads, the machining efficiency can be significantly improved. This structure can simultaneously machine multiple positions of the workpiece, reducing the clamping frequency and shortening the workpiece machining cycle. However, multiple EDM heads also have some limitations. First, due to the increase in the number of heads, the flexibility of multi-head machine tools is limited, making it difficult to meet the overall machining needs of larger-sized workpieces. For example, when machining large and complex molds, it is not possible to cover all key areas of the mold simultaneously, resulting in the need to frequently change machining positions during machining, increasing non-machining time, and possibly causing collisions between machine heads, damaging the machine tool.

[0046] The technical solutions in the present application will be described clearly and completely in the present application by combining with the drawings in the present application. Obviously, the described embodiments are only some of the embodiments in the present application, but not all the embodiments. Based on the embodiments in the present application, all the other embodiments obtained by those skilled in the art without creative work belong to the scope of protection of the present application.

[0047] Please refer to Figure 1 and Figure 2 The present application provides a symmetrical combined head machine tool structure, comprising: a base 01, a first column 02, a second column 03, a first group of EDM machine heads 04 and a second group of EDM machine heads 05.

[0048] The base 01 is provided with a working groove 06, the first column 02 is arranged on one side of the base 01, and the second column 03 is arranged on the other side of the base 01.

[0049] The first column 02 is provided with a first X-axis linear module 07, and the second column 03 is provided with a second X-axis linear module 08.

[0050] The first group of EDM machine heads 04 is connected with the first X-axis linear module 07, and the second group of EDM machine heads 05 is connected with the second X-axis linear module 08.

[0051] The first group of EDM machine heads 04 and the second group of EDM machine heads 05 each contain at least three machine heads.

[0052] Any one of the EDM machine heads is provided with an independent Y-axis linear module and a Z-axis linear module and is connected with an EDM power supply.

[0053] The first column 02, the second column 03 and the base 01 are an integral whole, serving as the installation reference of the machine tool, and the base 01 is provided with a working groove 06 for placing the workpiece to be processed. The first column 02 and the second column 03 are respectively arranged on the two sides of the base 01. On the first column 02, a first X-axis linear module 07 is installed, and a first group of EDM machine heads 04 is connected to the first X-axis linear module 07. On the second column 03, a second X-axis linear module 08 is installed, and a second group of EDM machine heads 05 is connected to the second X-axis linear module 08. The two sets of X-axis linear modules can provide the EDM machine heads with linear motion in the X-axis direction. Each group of EDM machine heads includes at least three independent EDM machine heads, and the EDM machine heads can simultaneously perform electrical discharge machining on different parts of the workpiece. Each EDM machine head is equipped with an independent Y-axis linear module and a Z-axis linear module. The Y-axis linear module is used to move the machine head in a direction perpendicular to the X-axis, and the Z-axis linear module is used to move the machine head in a direction perpendicular to the XY plane. Each EDM machine head can be positioned at any position on the workpiece in three-dimensional space. When the machine tool is working, the control system controls the first X-axis linear module 07 and the second X-axis linear module 08 according to the machining path and parameters of the preset program, and drives the first group of EDM machine heads 04 and the second group of EDM machine heads 05 to move in the X-axis direction. At the same time, the Y-axis linear module and the Z-axis linear module on each machine head also make fine adjustments in the Y-axis and Z-axis directions according to the instructions of the control system, to ensure that the machine head can accurately reach the machining position of the workpiece. When the EDM machine head reaches the specified position, the electrical discharge machining power supply supplies power to the EDM machine head, and the workpiece is machined by the machine head. Since each machine head works independently, different parts of the workpiece can be machined simultaneously.

[0054] As can be seen from the above embodiments, the beneficial effects brought by the scheme of the present application are as follows: through the first group of EDM machine heads 04 and the second group of EDM machine heads 05, the machine tool can simultaneously process multiple areas of the workpiece, shortening the machining cycle. The first X-axis linear module 07, the second X-axis linear module 08, the independent Y-axis and Z-axis linear modules enable each machine head to quickly and accurately position on the working area in three-dimensional space, reducing positioning time and waiting time and improving overall machining efficiency. The use of symmetrical layout makes the positioning of the machine tool in the X-axis direction consistent, and multiple EDM machine heads cooperate with each other, enabling the machine tool to machine workpieces of various complex shapes and sizes, improving the flexibility and adaptability of machining.

[0055] Please refer to Figures 1 to 5 In an optional embodiment, the first group of EDM machine heads 04 includes a first machine head 041, a second machine head 042 and a third machine head 043.

[0056] The first head 041, the second head 042 and the third head 043 are connected with the first X-axis linear module 07.

[0057] The second group of discharge machining heads 05 includes a fourth head 051, a fifth head 052 and a sixth head 053.

[0058] The fourth head 051, the fifth head 052 and the sixth head 053 are connected with the second X-axis linear module 08.

[0059] The machine tool as a whole is mainly composed of a base 01, a first vertical column 02, a second vertical column 03, a first group of discharge machining heads 04 and a second group of discharge machining heads 05. The first group of discharge machining heads 04 includes a first head 041, a second head 042 and a third head 043, which are respectively connected with the first X-axis linear module 07. The second group of discharge machining heads 05 includes a fourth head 051, a fifth head 052 and a sixth head 053, which are respectively connected with the second X-axis linear module 08. When the machine tool works, the control system will control the first X-axis linear module 07 and the second X-axis linear module 08 according to the machining path and parameters of the preset program, so as to drive the first group of discharge machining heads 04 and the second group of discharge machining heads 05 to move in the X-axis direction. The first X-axis linear module 07 and the second X-axis linear module 08 will drive the first head 041, the second head 042, the third head 043, the fourth head 051, the fifth head 052 and the sixth head 053 to move along the X-axis direction to the preset machining area, and then through the Y-axis linear module and the Z-axis linear module on each head, fine adjustment is carried out in the Y-axis and Z-axis directions, so as to ensure that the head can accurately reach the machining position of the workpiece. When the discharge machining head reaches the specified position, the discharge machining power supply supplies power to the discharge machining head, and the discharge machining is carried out on the workpiece through the head.

[0060] As can be seen from the above embodiments, the beneficial effects brought by the scheme of the present application are as follows: because six independent discharge machining heads are configured, the machine tool can simultaneously process different areas of the workpiece, shortens the processing cycle and improves the overall processing efficiency. Each discharge machining head is independently connected to the X-axis linear module, and each discharge machining head is equipped with independent Y-axis and Z-axis linear modules, which ensures that each head can independently move in three-dimensional space, further enhancing the flexibility and processing range of the machine tool. The machine tool can be fully utilized, reducing the idle time of a single head, thereby improving the resource utilization rate. The configuration of the six heads enables the machine tool to flexibly cope with various complex shape and size workpiece processing requirements, improving the flexibility and adaptability of processing.

[0061] Please refer to Figure 5 and Figure 6In an optional embodiment, the first X-axis linear module 07 comprises a first X-axis ram X1, a second X-axis ram X2, and a third X-axis ram X3.

[0062] The first head 041 is connected to the first X-axis ram X1, the second head 042 is connected to the second X-axis ram X2, and the third head 043 is connected to the third X-axis ram X3.

[0063] The second X-axis linear module 08 comprises a fourth X-axis ram X4, a fifth X-axis ram X5, and a sixth X-axis ram X6.

[0064] The fourth head 051 is connected to the fourth X-axis ram X4, the fifth head 052 is connected to the fifth X-axis ram X5, and the sixth head 053 is connected to the sixth X-axis ram X6.

[0065] The first X-axis ram X1, the second X-axis ram X2, and the third X-axis ram X3 are arranged on the first X-axis linear module 07 and connected to the first head 041, the second head 042, and the third head 043, respectively. The fourth X-axis ram X4, the fifth X-axis ram X5, and the sixth X-axis ram X6 are arranged on the second X-axis linear module 08 and connected to the fourth head 051, the fifth head 052, and the sixth head 053, respectively. During operation of the machine tool, the control system controls the first X-axis linear module 07 and the second X-axis linear module 08 according to the machining path and parameters of the preset program, and drives the first group of electrical discharge machining heads 04 and the second group of electrical discharge machining heads 05 to move in the X-axis direction. The first X-axis ram X1 on the first X-axis linear module 07 drives the first head 041, the second X-axis ram X2 drives the second head 042, and the third X-axis ram X3 drives the third head 043 to move in the X-axis direction. The fourth X-axis ram X4 drives the fourth head 051, the fifth X-axis ram X5 drives the fifth head 052, and the sixth X-axis ram X6 drives the sixth head 053 to move in the X-axis direction. The six X-axis rams drive the corresponding connected heads to move in the X-axis direction to the preset machining area during operation, and then the Y-axis linear module and the Z-axis linear module on each head are used for fine adjustment in the Y-axis and Z-axis directions to ensure that the heads can accurately reach the machining position of the workpiece. When the electrical discharge machining head reaches the specified position, the electrical discharge machining power supply supplies power to the electrical discharge machining head, and the workpiece is machined by the head.

[0066] As can be seen from the above embodiments, the beneficial effects brought by the scheme of the present application are as follows: the machine tool is configured with two X-axis linear modules, each of which is connected with three discharge machining heads, realizing parallel machining. The machine tool can simultaneously machine different areas of the workpiece, significantly improving the machining efficiency and shortening the production cycle. Each discharge machining head is connected with a corresponding X-axis linear module through an independent X-axis ram, which helps to reduce vibration and error in the machining process, improve the machining precision, stability and linkage between the heads.

[0067] Referring to Figures 1 to 4 In an optional embodiment, the Y-axis linear modules include: a first Y-axis linear module Y1, a second Y-axis linear module Y2, a third Y-axis linear module Y3, a fourth Y-axis linear module Y4, a fifth Y-axis linear module Y5 and a sixth Y-axis linear module Y6.

[0068] The first head 041 is connected with the first Y-axis linear module Y1, the second head 042 is connected with the second Y-axis linear module Y2, the third head 043 is connected with the third Y-axis linear module Y3, the fourth head 051 is connected with the fourth Y-axis linear module Y4, the fifth head 052 is connected with the fifth Y-axis linear module Y5, and the sixth head 053 is connected with the sixth Y-axis linear module Y6.

[0069] Each discharge machining head is connected with a corresponding independent Y-axis linear module, which is used to drive the corresponding connected discharge machining head to move in the Y-axis direction. Each head is connected to the ram of the corresponding Y-axis linear module. When the motor of the corresponding Y-axis linear module receives the instruction of the control system, it starts and drives the transmission mechanism, thereby driving the corresponding discharge machining head to move along the Y-axis direction. Because each Y-axis linear module is independently controlled, each head can independently move linearly in the Y-axis direction.

[0070] As can be seen from the above embodiments, the beneficial effects brought by the scheme of the present application are as follows: each discharge machining head is connected with an independent Y-axis linear module, so that the machine tool can complete the task faster and shorten the production cycle when machining large workpieces or when multiple work areas need to perform machining tasks simultaneously. Each head is independently connected with a Y-axis linear module, which helps to reduce vibration and error in the machining process, improve the machining precision, stability and linkage between the heads. By adjusting the position of each head, the machine tool can flexibly cope with different machining tasks and requirements, improving the flexibility of the machining process.

[0071] Referring to Figures 1 to 6In an optional embodiment, the Z-axis linear module includes a first Z-axis linear module Z1, a second Z-axis linear module Z2, a third Z-axis linear module Z3, a fourth Z-axis linear module Z4, a fifth Z-axis linear module Z5, and a sixth Z-axis linear module Z6.

[0072] The first head 041 is connected to the first Z-axis linear module Z1, the second head 042 is connected to the second Z-axis linear module Z2, the third head 043 is connected to the third Z-axis linear module Z3, the fourth head 051 is connected to the fourth Z-axis linear module Z4, the fifth head 052 is connected to the fifth Z-axis linear module Z5, and the sixth head 053 is connected to the sixth Z-axis linear module Z6.

[0073] Each discharge machining head is connected to a corresponding independent Z-axis linear module, which is used to drive the corresponding connected discharge machining head to move in the Z-axis direction. Each head is connected to the ram of the corresponding Z-axis linear module. When the motor of the corresponding Z-axis linear module receives the instruction of the control system, it starts and drives the transmission mechanism, thereby driving the corresponding discharge machining head to move along the Z-axis direction. When the discharge machining head moves to the corresponding working area through the X-axis linear module and the Y-axis linear module, the Z-axis linear module drives the discharge machining head to move to the corresponding Z-axis processing area to perform the processing task. Since each Z-axis linear module is independently controlled, each head can independently move linearly in the Z-axis direction without being affected by the movement of other heads.

[0074] As can be seen from the above embodiments, the beneficial effects brought by the present application scheme are as follows: Each discharge machining head is connected to an independent Z-axis linear module, which enables the machine tool to complete the task faster and shorten the production cycle when processing large workpieces or when multiple working areas need to perform processing tasks simultaneously. Each head is independently connected to a Z-axis linear module, which enables the machine tool to be more flexible in responding to the processing needs of complex-shaped workpieces, ensures that each processing area can achieve the expected processing depth and quality, and helps to reduce vibration and errors during processing, thereby improving the processing precision, stability, and linkage between the discharge machining heads.

[0075] Please refer to Figures 1 to 4 In an optional embodiment, the first column 02 and the second column 03 are arranged side by side, and the first X-axis linear module 07 and the second X-axis linear module 08 are arranged in parallel.

[0076] The first column 02, the second column 03 and the base 01 are an integral whole, serving as the installation reference of the machine tool. The first column 02 and the second column 03 are arranged side by side on the base 01, providing a stable support structure for the machine tool, for mounting the first X-axis linear module 07 and the second X-axis linear module 08. The first X-axis linear module 07 and the second X-axis linear module 08 are arranged on the first column 02 and the second column 03, and the first X-axis linear module 07 and the second X-axis linear module 08 are arranged in parallel. Because of the parallel arrangement of the two X-axis linear modules, the movement of the two X-axis linear modules in the X-axis direction is consistent, thereby ensuring the machining precision and stability of the machine tool in the X-axis direction.

[0077] As can be seen from the above embodiments, the beneficial effects brought by the scheme of the present application are as follows:

[0078] The first column 02 and the second column 03 are arranged side by side, providing a more stable support structure for the machine tool, which helps to disperse the load of the machine tool during work, reduces vibration and deformation, and thus improves the precision and stability of machining. The first X-axis linear module 07 and the second X-axis linear module 08 arranged in parallel ensure that the directions of movement of the two X-axis linear modules in the X-axis direction are consistent, and three electric discharge machining heads can be arranged on each X-axis linear module, further increasing the processing flexibility and adaptability of the machine tool. Since each head can independently move in the X-axis, Y-axis and Z-axis directions, the machine tool can simultaneously or alternately process different areas of the workpiece. This design significantly improves the processing efficiency, and is particularly suitable for large workpieces or tasks that require multiple areas to be processed simultaneously.

[0079] Please refer to Figures 1 to 4 In an optional embodiment, the working groove 06 is arranged between the first column 02 and the second column 03.

[0080] The working groove 06 is provided with a clamping tool 09, which is used to fix the workpiece to be machined.

[0081] The working groove 06 is arranged between the first column 02 and the second column 03, facilitating the work of the first group of EDM machine heads 04 and the second group of EDM machine heads 05. The working groove 06 is provided with a clamping tool 09, which can be replaced. When processing different parts, the appropriate clamping tool 09 is replaced to fix the workpiece in the working groove 06. The clamping tool 09 can prevent the workpiece from moving during the work, thereby improving the machining precision. Before the machine tool works, the operator first fixes the workpiece to be processed in the working groove 06 through the clamping tool 09. The working groove 06 is provided with protective doors on both sides. When the machine tool works, the control system will control the first X-axis linear module 07 and the second X-axis linear module 08 according to the machining path and parameters of the preset program, respectively, to drive the first group of EDM machine heads 04 and the second group of EDM machine heads 05 to move in the X-axis direction. At the same time, the Y-axis linear module and the Z-axis linear module on each machine head will also be finely adjusted in the Y-axis and Z-axis directions according to the instructions of the control system, so as to ensure that the machine head can accurately reach the machining position of the workpiece. When the EDM machine head reaches the specified position, the EDM power supply supplies power to the EDM machine head, and the workpiece is processed by the machine head through discharge machining. Since each machine head works independently, different parts of the workpiece can be processed at the same time.

[0082] As can be seen from the above embodiments, the beneficial effects brought by the scheme of the present application are as follows: the clamping tool 09 can ensure the accurate position of the workpiece to be processed in the machine tool coordinate system, avoiding processing errors caused by workpiece movement or vibration. It helps to improve the machining precision and ensures that the workpiece meets the expected machining quality and size requirements.

[0083] Please refer to Figure 1 and Figure 6 In an optional embodiment, servo driving devices are arranged on the first X-axis linear module 07, the second X-axis linear module 08, the Y-axis linear module and the Z-axis linear module, and the servo driving devices are controlled by a feedback control system.

[0084] The feedback control system is used to drive the first X-axis linear module 07 and the second X-axis linear module 08, and the EDM machine head moves in the X-axis direction through the first X-axis linear module 07 and the second X-axis linear module 08.

[0085] The feedback control system is used to drive the Y-axis linear module, and the EDM machine head moves in the Y-axis direction through the Y-axis linear module.

[0086] The feedback control system is used to drive the Z-axis linear module, and the EDM head moves in the Z-axis direction through the Z-axis linear module.

[0087] The servo drive device is responsible for converting electrical energy into mechanical energy to drive the linear modules of each axis to move. The feedback control system monitors the position, speed, and acceleration of each linear module in real time through the sensor components on the machine tool, and compares these information with the preset machining path and parameters. According to the comparison result, the feedback control system adjusts the output of the servo drive device to ensure that each linear module can move accurately according to the preset machining path and parameters. When X-axis movement is needed, the feedback control system drives the servo drive device on the first X-axis linear module 07 and the second X-axis linear module 08. The servo drive device drives the ram in the linear module to move, and drives the EDM head to move in the X-axis direction. When Y-axis movement is needed, the feedback control system drives the servo drive device on the Y-axis linear module. The servo drive device drives the ram in the Y-axis linear module to move, thereby driving the EDM head to move in the Y-axis direction. When Z-axis movement is needed, the feedback control system drives the servo drive device on the Z-axis linear module. The servo drive device drives the ram in the Z-axis linear module to move, thereby driving the EDM head to move in the Z-axis direction. The sensor components monitor the position information of the EDM head in real time and feed back to the feedback control system to ensure that the EDM head can move accurately according to the preset machining path. During the machining process, the feedback control system constantly adjusts the output of the servo drive device according to the preset machining parameters and the actual motion parameters fed back by the sensor components. Through this closed-loop control mode, the machine tool can realize accurate control of the movement of the EDM head, thereby ensuring the machining quality and precision.

[0088] As can be seen from the above embodiments, the beneficial effects brought by the present application are as follows: the servo drive device cooperates with the feedback control system to realize accurate control of the movement of each linear module. By monitoring and adjusting the motion parameters in real time, the machine tool can ensure that the EDM head moves accurately according to the preset machining path and parameters, improving the machining precision and the linkage between the EDM heads. The servo drive device has the characteristics of fast response and high-speed movement, which can quickly adjust the EDM head to reach the corresponding position and shorten the machining cycle. The feedback control system can optimize the machining path, reduce unnecessary movement, and further improve the machining efficiency. By adjusting the output of the servo drive device and the parameters of the feedback control system, the machine tool can process workpieces of different shapes, sizes, and materials to realize flexible and diverse machining tasks.
