Abstract
Description
Technical Field
[0001] This disclosure relates to the field of die casting processing technology, and more specifically, to a die casting processing system. Background Technology
[0002] Die castings are widely used in the automotive, aerospace, and electronics industries due to their high forming precision and excellent mechanical properties. However, die castings often require precision machining after forming to meet stringent dimensional and surface quality requirements. In related technologies, dual-spindle machining centers are commonly used for machining die castings. However, due to machine tool structure limitations (to avoid machining interference), dual-spindle machining centers cannot accommodate multiple machining axes for simultaneous processing, significantly reducing machining efficiency. Utility Model Content
[0003] To overcome the problems existing in the related technologies, this disclosure provides a die casting mold ejection structure and a die casting mold.
[0004] According to an embodiment of this disclosure, a die-casting part processing system is provided, comprising: Base; A clamping assembly, which is connected to the base and used to clamp and position the die-cast part; Multiple processing robots, each of which includes a multi-degree-of-freedom spindle module, and each of which is connected to the base; At least two processing robots are respectively arranged on each of the opposite sides of the clamping assembly, and the processing robots located on both sides of the clamping assembly are symmetrically arranged about the clamping assembly.
[0005] In some possible implementations, different processing robots located on the same side can process the die casting from different sides. Each robot is equipped with a multi-degree-of-freedom spindle module, enabling it to process the die casting from different angles. This allows the system to handle complex die casting geometries. The fact that different robots on the same side can process different sides of the die casting avoids multiple flipping and re-clamping of the workpiece, shortens the processing cycle, and improves production efficiency.
[0006] In some possible implementations, the machining robot includes a base, an end effector, a linkage mechanism, a first rotary joint, and a second rotary joint. The linkage mechanism comprises multiple links rotatably connected end-to-end. One end of the linkage mechanism is connected to the end effector via the first rotary joint, and the other end is rotatably connected to the base via the second rotary joint. This linkage mechanism, consisting of multiple rotatably connected links, combined with the first and second rotary joints, gives the machining robot a high degree of motion flexibility, enabling it to move in multiple degrees of freedom in three-dimensional space. For example, it can easily move and rotate in horizontal, vertical, and inclined directions. This allows the robot to approach die-cast parts at various angles and reach different positions for machining operations, meeting the complex shapes and diverse processing requirements of die-cast parts.
[0007] In some possible implementations, the end effector includes a first rotary module, a linear feed module, and the multi-degree-of-freedom spindle module, which is connected to the linkage mechanism via the first rotary module and the linear feed module. On one hand, the first rotary module enables the multi-degree-of-freedom spindle module to rotate around a specific axis, allowing the end effector to process the die-casting from different angles. For die-castings with complex curved surfaces or irregular shapes, the spindle angle can be easily adjusted to achieve omnidirectional processing. On the other hand, the linear feed module can drive the multi-degree-of-freedom spindle module to move precisely along a specific straight line. During processing, the linear feed amount and speed of the spindle can be flexibly controlled according to different processing requirements (such as milling).
[0008] In some possible implementations, the end effector has a first operating state and a second operating state. In the first operating state, the feed direction of the linear feed module is parallel to the axis of the multi-degree-of-freedom spindle module. In the second operating state, the feed direction of the linear feed module is perpendicular to the axis of the multi-degree-of-freedom spindle module. Thus, in the first operating state, the feed direction of the linear feed module is parallel to the axis of the multi-degree-of-freedom spindle module, which is suitable for depth-oriented machining operations, such as drilling and deep groove milling. In the second operating state, the feed direction of the linear feed module is perpendicular to the axis of the multi-degree-of-freedom spindle module, which is suitable for milling die-cast parts.
[0009] In some possible implementations, the die-casting machining system further includes a shielding cover, which covers the base and together with the base forms a machining cavity, within which the fixture assembly and multiple machining robots are housed. On one hand, the enclosed machining cavity effectively isolates the influence of the external environment, such as dust, temperature changes, and airflow fluctuations, thereby reducing interference with machining accuracy and improving the stability of the machining process. On the other hand, machining robots generate noise during operation, especially when multiple robots are running simultaneously; the shielding cover acts as a sound insulator, confining the noise within the machining cavity and reducing its propagation to the surrounding environment, thus minimizing noise pollution for workshop workers and the surrounding environment.
[0010] In some possible implementations, the die-casting processing system further includes an oil mist collection processor for collecting oil mist generated by the multiple processing robots during operation. By incorporating the oil mist collection processor, oil mist generated during processing can be effectively collected and removed, reducing the concentration of suspended particles and oil mist in the work area, improving the respiratory health and eye comfort of operators, and preventing oil mist accumulation from interfering with sensors, vision systems, and fixture surfaces. This reduces the probability of false readings, fixture contamination, and workpiece surface defects, improving processing consistency and repeatability.
[0011] In some possible implementations, the oil mist collection processor includes an oil storage tank, an oil processor, a fan, an oil delivery pipe, and an oil collection hood. One end of the oil delivery pipe is connected to the oil outlet of the oil collection hood, and the other end of the oil delivery pipe is connected to the inlet of the oil processor. The outlet of the oil processor is connected to the oil delivery pipe, and the fan is connected to the oil delivery pipe. The oil collection hood has a suction port connected to the oil outlet, and the suction port is located above the plurality of processing robots. During the processing of the die-casting parts in the above-mentioned die-casting parts processing system, the fan is started, thereby creating a negative pressure inside the oil collection hood. The oil mist generated by the processing robots is sucked into the oil collection hood under the action of negative pressure, and then enters the oil processor through the oil delivery pipe. After being processed in the oil processor, it is stored in the oil storage tank.
[0012] In some possible implementations, the die-casting processing system further includes a chip removal assembly, which comprises a transmission module and a chip collection box. One end of the transmission module is positioned below the processing robot, and the other end extends into the interior of the chip collection box. By placing the transmission module below the processing robot, the chips generated during processing can be promptly transported away, preventing chip corrosion of the equipment, making equipment cleaning easier, and effectively ensuring the processing accuracy of the die-cast parts.
[0013] In some possible implementations, the transmission module includes a first conveyor belt and a second conveyor belt arranged side by side. The plurality of processing robots include a first robot group disposed on one side of the fixture assembly and a second robot group disposed on the fixture assembly. Each of the first and second robot groups includes at least two processing robots. The first conveyor belt is positioned below the first robot group, and the second conveyor belt is positioned below the second robot group. The placement of the first and second conveyor belts below the first and second robot groups allows for precise collection and transport of debris generated by each robot group, preventing debris accumulation in the processing area, ensuring a clean working environment around each processing robot, and guaranteeing a stable processing flow.
[0014] In some possible implementations, the transmission module further includes a guide member, which is constructed as a shell-like structure that is higher in the middle and lower on both sides. The first conveyor belt has a first sidewall disposed close to the second conveyor belt, and the second conveyor belt has a second sidewall disposed close to the first sidewall. One side of the guide member overlaps with the first sidewall, and the other side of the guide member overlaps with the second sidewall. When debris falls onto the edge of the conveyor belt, due to the inclined arrangement of the guide member, the debris is less likely to adhere to the first and second sidewalls and will be guided to the center of the conveyor belt, preventing debris from accumulating on the first and second sidewalls, ensuring the normal operation of the first and second conveyor belts, and improving the chip removal efficiency.
[0015] In some possible implementations, the die-casting machining system further includes a cooling device for cooling the multi-degree-of-freedom spindle module. The cooling device effectively dissipates heat, suppresses temperature rise in the multi-degree-of-freedom spindle module, and maintains the operating temperature within a safe range, thereby minimizing thermal deformation, ensuring machining accuracy, and extending the service life of the multi-degree-of-freedom spindle module and its internal precision components.
[0016] In some possible implementations, the cooling device includes a cooling pipe, a radiator, and a water pump. The multi-degree-of-freedom spindle module is equipped with a heat exchange pipeline. One end of the cooling pipe is connected to the inlet of the heat exchange pipeline, and the other end is connected to the inlet of the radiator. The water pump is connected to the cooling pipe. The water pump delivers coolant through the cooling pipe to the heat exchange pipeline of the multi-degree-of-freedom spindle module. The coolant flows within the heat exchange pipeline, exchanging heat with the heat generated by the spindle module. After absorbing heat, the coolant flows back to the radiator through the cooling pipe. In the radiator, the coolant dissipates the heat and is then pumped back to the heat exchange pipeline by the water pump, forming a closed-loop cooling system that continuously removes heat generated by the spindle module, effectively controlling the temperature of the multi-degree-of-freedom spindle module and preventing problems such as spindle thermal deformation and lubrication failure due to excessive temperature.
[0017] The technical solutions provided by the embodiments of this disclosure may include the following beneficial effects: On the one hand, multiple processing robots can process die castings from different directions and angles simultaneously. The greater freedom of motion allows the robots to flexibly adjust the posture of the multi-degree-of-freedom spindle modules, enabling all-round and synchronous processing of the complex surface of the die castings. This avoids multiple clamping and adjustment, realizes multi-station and parallel operation, and shortens the overall processing cycle.
[0018] On the other hand, the symmetrical arrangement allows the processing robots on both sides to simultaneously perform processing operations on corresponding parts of the die casting. When one robot completes a certain process, the other robot also completes the corresponding process almost synchronously, avoiding the situation where one robot waits for the other to finish its work due to an asymmetrical arrangement, further improving the continuity and efficiency of the processing flow. In addition, the symmetrical arrangement can make the external forces on the die casting more uniform during the processing. For example, when drilling, the symmetrical robots on both sides can drill at the same time, which can effectively avoid displacement or deformation of the die casting due to uneven force on one side, thereby ensuring the positional and dimensional accuracy of the drilling and improving the overall processing quality of the die casting.
[0019] In addition, compared to large, fixed machining centers, robotic systems can be deployed and scheduled more flexibly, potentially leading to better space and equipment utilization.
[0020] It should be understood that the above general description and the following detailed description are exemplary and explanatory only, and are not intended to limit this disclosure. Attached Figure Description

Detailed Implementation
[0023] The specific embodiments of this disclosure will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are for illustration and explanation only and are not intended to limit this disclosure.
[0024] In this disclosure, unless otherwise stated, directional terms are used only for the convenience of describing the disclosure and for simplifying the description, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or a specific orientation construction and operation, and therefore should not be construed as a limitation of the disclosure. For example, the directional terms in this scheme are defined based on the actual use of the die-casting mold, and "height direction" and "width direction" can be referred to... Figure 1The front-to-back direction and width direction are shown. "Inner" and "outer" refer to the inner and outer contours of the corresponding components. In addition, the terms "first," "second," etc. are used to distinguish one element from another and do not have any order or importance.
[0025] In the description of this disclosure, it should also be noted that, unless otherwise expressly specified and limited, the terms "set up," "connect," "link," and "install" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in this disclosure according to the specific circumstances.
[0026] like Figures 1 to 5 As shown, this disclosure provides a die casting processing system 1, including a base 10, a clamping assembly 20 and a plurality of processing robots 30. The clamping assembly 20 is connected to the base 10 and is used to clamp and position the die casting. Each processing robot 30 includes a multi-degree-of-freedom spindle module 323. Each processing robot 30 is connected to the base 10. At least two processing robots 30 are respectively arranged on opposite sides of the clamping assembly 20. The processing robots 30 located on both sides of the clamping assembly 20 are symmetrically arranged about the clamping assembly 20.
[0027] Through the above technical solution, on the one hand, multiple processing robots 30 can process die castings from different directions and angles at the same time. The greater freedom of movement allows the robot to flexibly adjust the posture of the multi-degree-of-freedom spindle module 323, realize all-round and synchronous processing of the complex surface of the die casting, avoid multiple clamping and adjustment, realize multi-station parallel operation, and shorten the overall processing cycle.
[0028] On the other hand, the symmetrical arrangement allows the two processing robots 30 to simultaneously perform processing operations on corresponding parts of the die casting. When one robot completes a certain process, the other robot also completes the corresponding process almost synchronously, avoiding the situation where one robot waits for the other to finish its work due to the asymmetrical arrangement, further improving the continuity and efficiency of the processing flow. In addition, the symmetrical arrangement can make the external force on the die casting more uniform during the processing. For example, when drilling, the two symmetrical robots drill at the same time, which can effectively avoid displacement or deformation of the die casting due to uneven force on one side, thereby ensuring the positional accuracy and dimensional accuracy of the drilling and improving the overall processing quality of the die casting.
[0029] In addition, compared to large, fixed machining centers, robotic systems can be deployed and scheduled more flexibly, potentially leading to better space and equipment utilization.
[0030] In some possible implementations, different processing robots 30 located on the same side can process the die casting from different sides. Each robot is equipped with a multi-degree-of-freedom spindle module 323, which can process the die casting from different angles. This allows the system to handle complex die casting geometries. Different robots on the same side can process different sides of the die casting, avoiding multiple flipping and re-clamping of the workpiece, shortening the processing cycle, and improving production efficiency.
[0031] For example, one of the multiple processing robots 30 located on the same side of the fixture assembly 20 can process the front of the die casting held on the fixture assembly 20, while another robot located on the same side can process the side of the die casting on the fixture assembly 20, thereby improving processing efficiency.
[0032] Similarly, the same applies to the multiple processing robots 30 on the other side of the fixture assembly 20, which will not be described in detail here. In this way, under the joint action of multiple symmetrically arranged processing robots 30 on both sides of the fixture assembly, synchronous processing of different sides of the die casting is achieved, which not only improves the processing efficiency of the die casting, but also improves the consistency of processing on different sides.
[0033] This disclosure does not limit the specific structure of the aforementioned machining robot 30. It should be noted that the machining robot 30 should be able to achieve movement in at least three dimensions, that is, be able to drive the multi-degree-of-freedom spindle module 323 to reciprocate in multiple directions. In some possible embodiments, such as... Figure 4 As shown, the machining robot 30 includes a base 31, an end effector 32, a linkage mechanism 33, a first rotary joint 34, and a second rotary joint 35. The linkage mechanism 33 includes multiple links that are rotatably connected end-to-end. One end of the linkage mechanism 33 is connected to the end effector 32 via the first rotary joint 34, and the other end of the linkage mechanism 33 is rotatably connected to the base 31 via the second rotary joint 35. The linkage mechanism 33, composed of multiple rotatably connected links, in conjunction with the first rotary joint 34 and the second rotary joint 35, gives the machining robot 30 a high degree of motion flexibility, enabling it to achieve multiple degrees of freedom of movement in three-dimensional space. For example, it can easily move and rotate in horizontal, vertical, and inclined directions. This allows the robot to approach the die-cast parts at various angles and reach different positions for machining operations, meeting the complex shapes and diverse machining needs of the die-cast parts.
[0034] For example, when dealing with die-cast parts with complex curved surfaces or internal structures, the machining robot 30 with this structure can flexibly adjust the posture and position of the end effector 32. For instance, for die-cast automotive engine parts with irregular surfaces, the robot can use the coordinated movement of the linkage mechanism 33 and the rotary joint to make the end effector 32 fit tightly against the surface of the casting, performing precise milling, grinding, drilling, and other machining operations, without being limited by the shape of the casting.
[0035] In some possible implementations, such as Figure 4 As shown, the end effector 32 includes a first rotary module 321, a linear feed module 322, and a multi-degree-of-freedom spindle module 323. The multi-degree-of-freedom spindle module 323 is connected to the linkage mechanism 33 through the first rotary module 321 and the linear feed module 322. On the one hand, the first rotary module 321 enables the multi-degree-of-freedom spindle module 323 to rotate around a specific axis, allowing the end effector 32 to process the die-casting from different angles. For die-castings with complex curved surfaces or irregular shapes, the spindle angle can be easily adjusted to achieve omnidirectional processing. On the other hand, the linear feed module 322 can drive the multi-degree-of-freedom spindle module 323 to move precisely along a specific straight line. During processing, the linear feed amount and speed of the spindle can be flexibly controlled according to different processing requirements (such as milling).
[0036] For example, in one exemplary embodiment provided in this disclosure, the end effector 32 may have a first operating state and a second operating state. In the first operating state, the feed direction of the linear feed module 322 is parallel to the axis of the multi-degree-of-freedom spindle module 323. In the second operating state, the feed direction of the linear feed module 322 is perpendicular to the axis of the multi-degree-of-freedom spindle module 323. Thus, in the first operating state, the feed direction of the linear feed module 322 is parallel to the axis of the multi-degree-of-freedom spindle module 323, which is suitable for depth-oriented machining operations, such as drilling and deep groove milling. In the second operating state, the feed direction of the linear feed module 322 is perpendicular to the axis of the multi-degree-of-freedom spindle module 323, which is suitable for milling die-cast parts.
[0037] Of course, the end effector 32 provided in this solution may also have other working states, such as the feed direction of the linear feed module 322 being neither parallel to nor perpendicular to the multi-degree-of-freedom spindle module 323. This disclosure does not impose any restrictions on this.
[0038] In addition, the die casting machining system 1 provided in this disclosure may also include a tool magazine containing multiple tools. The tools can be detachably connected to the multi-degree-of-freedom spindle module 323, thereby allowing the replacement of different types of tools when different machining needs are met. Under the drive of the multi-degree-of-freedom spindle module 323, different die castings can be machined.
[0039] In some possible implementations, such as Figure 3 As shown, the die-casting processing system 1 also includes a shielding cover 40, which covers the base 10 and together with the base 10 forms a processing cavity. The fixture assembly 20 and multiple processing robots 30 are all housed within the processing cavity. On the one hand, the enclosed processing cavity effectively isolates the influence of the external environment, such as dust, temperature changes, and airflow fluctuations, thereby reducing interference with processing accuracy and improving the stability of the processing process. On the other hand, the processing robots 30 generate a certain amount of noise during operation, especially when multiple processing robots 30 are running simultaneously, the noise becomes more pronounced. The shielding cover 40 can play a sound insulation role, controlling the noise within the processing cavity, reducing the transmission of noise to the surrounding environment, and reducing noise pollution to workshop workers and the surrounding environment.
[0040] In addition, the cavity structure formed by the shield 40 and the base 10 can effectively prevent the splashing of debris, oil mist, coolant and other substances generated during the processing, thereby avoiding pollution of the external environment and safety hazards such as scratches to personnel.
[0041] like Figures 1 to 3 As shown, in some possible embodiments, the die-casting processing system 1 may further include an oil mist collection processor 50 for collecting oil mist generated by multiple processing robots 30 during operation. By setting up the oil mist collection processor 50, oil mist generated during processing (such as lubricating oil mist generated by lubricating oil on the cutting tool during processing) can be effectively collected and removed, reducing the concentration of suspended particles and oil mist in the working area, improving the respiratory health and eye comfort of operators, and preventing oil mist accumulation from interfering with sensors, vision systems, and fixture surfaces, reducing the probability of false detections, fixture contamination, and workpiece surface defects, and improving the consistency and repeatability of processing.
[0042] This disclosure does not limit the structure or oil mist collection method of the oil mist collection processor 50 described above. For example, in some possible embodiments, such as Figure 1 , Figure 2As shown, the oil mist collection processor 50 may include an oil storage tank 51, an oil processor 52, a fan, an oil delivery pipe 54, and an oil collection hood 55. One end of the oil delivery pipe 54 is connected to the oil outlet of the oil collection hood 55, and the other end of the oil delivery pipe 54 is connected to the inlet of the oil processor 52. The outlet of the oil processor 52 is connected to the oil delivery pipe 54, and the fan is connected to the oil delivery pipe 54. The oil collection hood 55 has a suction port connected to the oil outlet, and the suction port is located above the multiple processing robots 30. Thus, during the processing of the die-casting parts processing system 1, the fan is started, thereby creating a negative pressure inside the oil collection hood 55. The oil mist generated by the processing robots 30 is sucked into the oil collection hood 55 under the action of negative pressure, and then enters the oil processor 52 through the oil delivery pipe 54. After being processed in the oil processor 52, it is stored in the oil storage tank 51.
[0043] Furthermore, in the above scheme, since the oil mist will naturally diffuse upward during the processing, setting the air intake above the processing robot 30 can take advantage of the upward trend of the oil mist to more efficiently draw the oil mist into the oil collection hood 55.
[0044] In one exemplary embodiment provided in this disclosure, the air intake can be located above the cutting tool on the multi-degree-of-freedom spindle module 323 of the machining robot 30, thereby adsorbing the lubricating oil mist generated by the cutting tool during operation.
[0045] In addition, the oil mist collection processor 50 of this disclosure may also include a plurality of oil collection hoods 55, each of which is disposed above the cutting tool on the multi-degree-of-freedom spindle module 323 of each processing robot 30, so as to improve the absorption effect of oil mist.
[0046] During the die casting process, such as Figure 1 , Figure 2 As shown, a large amount of metal debris is generated. If this debris is not removed in time, it may mix into the machining area, affecting the contact accuracy between the machining tool and the die-casting part, leading to dimensional deviations. Therefore, in some possible embodiments, the die-casting machining system 1 may also include a chip removal assembly 60. The chip removal assembly 60 includes a transmission module 61 and a chip collection box 62. One end of the transmission module 61 is positioned below the machining robot 30, and the other end extends into the interior of the chip collection box 62. By positioning the transmission module 61 below the machining robot 30, the generated debris can be promptly transported away, preventing the debris from corroding the equipment, making equipment cleaning easier, and effectively ensuring the machining accuracy of the die-casting parts.
[0047] The debris generated by the 30 different processing robots during the processing is relatively concentrated in certain locations. Based on this, in some possible implementations, such as... Figure 5As shown, the transmission module 61 may include a first conveyor belt 610 and a second conveyor belt 611 arranged side by side. Multiple processing robots 30 include a first robot group disposed on one side of the fixture assembly 20 and a second robot group disposed on the fixture assembly 20. Each of the first and second robot groups includes at least two processing robots 30. The first conveyor belt 610 is positioned below the first robot group, and the second conveyor belt 611 is positioned below the second robot group. The placement of the first conveyor belt 610 and the second conveyor belt 611 below the second robot group allows for precise collection and transport of debris generated by each robot group, preventing debris accumulation in the processing area and ensuring a clean working environment around each processing robot 30, thus guaranteeing a stable processing process. Furthermore, the side-by-side first and second conveyor belts 610 and 611 can operate simultaneously, handling debris generated by different robot groups respectively. Compared to a single conveyor belt covering all processing robots 30, this parallel dual-conveyor belt mode significantly increases chip removal efficiency, reduces the dwell time of debris in the processing area, and improves overall processing efficiency.
[0048] Furthermore, the 30 processing robots are divided into a first robot group and a second robot group, each equipped with a corresponding conveyor belt. This modular design of the processing system allows each robot group to operate independently without interference, facilitating the allocation and management of different processing tasks. For example, if a conveyor belt malfunctions, only that conveyor belt needs to be repaired, without affecting the normal operation of other parts.
[0049] Because the debris generated during processing varies in size, it may accumulate or fall into the gap between the first conveyor belt 610 and the second conveyor belt 611. In some possible implementations, such as... Figure 5 As shown, the transmission module 61 also includes a guide member 63. The guide member 63 is a shell-shaped structure that is higher in the middle and lower on both sides. The first conveyor belt 610 has a first sidewall 6110 that is close to the second conveyor belt 611, and the second conveyor belt 611 has a second sidewall 6111 that is close to the first sidewall 6110. One side of the guide member 63 overlaps with the first sidewall 6110, and the other side of the guide member 63 overlaps with the second sidewall 6111. When debris falls on the edge of the conveyor belt, due to the inclined arrangement of the guide member 63, the debris is not easily attached to the first sidewall 6110 and the second sidewall 6111, and will be guided to the center of the conveyor belt, preventing debris from accumulating on the first sidewall 6110 and the second sidewall 6111, ensuring the normal operation of the first conveyor belt 610 and the second conveyor belt 611, and improving the chip removal efficiency.
[0050] The multi-degree-of-freedom spindle module 323 generates a large amount of heat during prolonged, high-intensity operation, causing thermal expansion and deformation of the spindle assembly. This thermal deformation directly affects the positioning accuracy of the tool and the cutting trajectory, leading to dimensional deviations, decreased surface roughness, and ultimately impacting the quality of the die-cast parts. Therefore, in one embodiment of this disclosure, the die-casting machining system 1 may further include a cooling device 70 for cooling the multi-degree-of-freedom spindle module 323. The cooling device 70 effectively dissipates heat, suppresses temperature rise in the multi-degree-of-freedom spindle module 323, and maintains the operating temperature within a safe range, thereby minimizing thermal deformation, ensuring machining accuracy, and extending the service life of the multi-degree-of-freedom spindle module 323 and its internal precision components.
[0051] This disclosure does not limit the cooling method or specific structure of the cooling device 70. For example, in one embodiment provided by this disclosure, the cooling device 70 may include a cooling pipe, a radiator, and a water pump. A heat exchange pipeline is provided on the multi-degree-of-freedom spindle module 323. One end of the cooling pipe is connected to the water inlet of the heat exchange pipeline, and the other end of the cooling pipe is connected to the water inlet of the radiator. The water pump is connected to the cooling pipe. The water pump delivers coolant through the cooling pipe to the heat exchange pipeline of the multi-degree-of-freedom spindle module 323. The coolant flows in the heat exchange pipeline and exchanges heat with the heat generated by the spindle module. After absorbing heat, the coolant flows back to the radiator through the cooling pipe. In the radiator, the coolant dissipates the heat and is then delivered to the heat exchange pipeline again by the water pump, forming a closed-loop cooling system that continuously removes the heat generated by the spindle module, effectively controlling the temperature of the multi-degree-of-freedom spindle module 323 and avoiding problems such as spindle thermal deformation and lubrication failure caused by excessive temperature.
[0052] In another embodiment provided in this disclosure, the cooling device 70 can also be a spray structure, through which coolant can be sprayed directly onto the multi-degree-of-freedom spindle module 323, thereby achieving cooling and temperature reduction of the multi-degree-of-freedom spindle module 323.
[0053] In this disclosure, such as Figure 1 As shown, the die-casting machining system 1 also includes a control module 80, which is connected to the base 10. The control module 80 includes a CNC module, a spindle control unit, and a motion control unit. The CNC module is connected to the spindle control unit and the motion control unit via signals. As the core of the system, the CNC module is responsible for receiving and processing machining commands, and is connected to the spindle control unit and the motion control unit via signals to achieve coordinated control of the multi-degree-of-freedom spindle module 323 and the fixture assembly 20.
[0054] For example, the spindle control unit is responsible for controlling parameters such as spindle speed and torque to meet the needs of different processing conditions. Similarly, the motion control unit can perform operations such as clamping, releasing, and flipping of the fixture assembly 20 to realize the loading and unloading of die-cast parts and position adjustment.
[0055] This disclosure does not limit the specific structure of the aforementioned clamping assembly 20. For example, the clamping assembly 20 may include a support 21, a clamping plate 22, and a second rotating module 23. The support 21 is connected to the base 10, and the clamping plate 22 is connected to the support 21 via the second rotating module 23. The clamping plate 22 is used to clamp the die-casting part, and the second rotating module 23 is used to drive the clamping plate 22 to rotate. By driving the clamping plate 22 to rotate via the second rotating module 23, the die-casting part clamped on the clamping plate 22 can achieve multi-angle rotation. For example, when processing the die-casting part, the operator does not need to frequently re-clamp the die-casting part and can perform processing operations from different directions and angles, such as drilling, milling, and grinding, thereby greatly improving the flexibility of the processing process and adapting to various complex processing needs.
[0056] This disclosure does not limit the specific structure of the second rotating module 23. In one exemplary embodiment provided in this disclosure, the second rotating module 23 may include a motor, a nut, and a lead screw. The nut and the lead screw form a lead screw-nut pair. The nut is connected to the output shaft of the motor, and the clamping plate 22 is connected to the lead screw. Thus, when it is necessary to drive the clamping plate 22 to rotate, the motor starts and drives the output shaft and the nut connected to the output shaft to rotate, thereby driving the lead screw, which forms a lead screw-nut pair with the nut, to rotate. Since the clamping plate 22 is connected to the lead screw, the rotation of the lead screw achieves the flipping of the rotating module.
[0057] To further improve the processing efficiency of die-cast parts located on clamping plates 22, in one exemplary embodiment provided in this disclosure, there can be two clamping plates 22, which are arranged in parallel and spaced apart, and respectively connected to both sides of the axial direction of the second rotating module 23. When a die-cast part on one clamping plate 22 is being processed, the operator can load a new die-cast part or unload a processed die-cast part on the other clamping plate 22. For example, when a die-cast part located on one side of the processing robot 30 is being processed by the processing robot 30, loading or unloading operations can be performed simultaneously on the clamping plate 22 located on the side opposite to the processing robot 30. After the processing robot 30 finishes processing the current die-cast part, the second rotating module 23 rotates, moving the clamping plate 22 with the new die-cast part clamped to the processing position, and immediately starting new processing, greatly reducing the equipment downtime caused by loading and unloading.
[0058] Alternatively, in other embodiments provided in this disclosure, where certain processing techniques allow, die-cast parts on two clamping plates 22 can be processed simultaneously, thereby doubling the number of die-cast parts processed in the same amount of time and directly improving processing efficiency.
[0059] In order to fix the die casting, a clamping member is also provided on the clamping plate 22, which can clamp the die casting on the side away from the clamping plate 22.
[0060] In this disclosure, the die-casting processing system 1 may further include a locating pin, which is connected to and protrudes from the clamping plate 22. The locating pin is adapted to the shape of a pre-set locating hole on the die-casting part. The locating pin includes a first section and a second section, with the second section connected between the first section and the clamping plate 22. The outer diameter of the first section is smaller than the outer diameter of the second section. Because the locating pin is adapted to the shape of the pre-set locating hole on the die-casting part, when the die-casting part is placed on the clamping plate 22, the locating pin can be accurately inserted into the locating hole, providing a precise positioning reference for the die-casting part. This ensures the positional accuracy of the die-casting part on the clamping plate 22, enabling subsequent processing operations to be performed accurately at the predetermined position, reducing processing errors caused by inaccurate positioning, and improving the processing quality of the die-casting part.
[0061] Specifically, during the process of assembling the die-cast part onto the clamping plate 22, since the outer diameter of the first section of the positioning pin is smaller than that of the second section, the smaller outer diameter of the first section can play a guiding role when installing the die-cast part, making it easier to align the positioning hole with the positioning pin. At the same time, accurate positioning is achieved through the further cooperation between the second section and the positioning hole, suppressing the lateral or torsional displacement of the fixture during clamping, flipping or impact, and improving process stability.

However, this disclosure is not limited to the specific details of the above embodiments. Within the scope of the technical concept of this disclosure, various simple modifications can be made to the technical solutions of this disclosure, and these simple modifications all fall within the protection scope of this disclosure.
[0063] It should also be noted that the various specific technical features described in the above specific embodiments can be combined in any suitable manner without contradiction. In order to avoid unnecessary repetition, this disclosure will not describe the various possible combinations separately.
[0064] Furthermore, various different embodiments of this disclosure can be combined in any way, as long as they do not violate the spirit of this disclosure, they should also be regarded as the content disclosed in this disclosure.
