Description

Technical Field

[0001] The present invention relates to the technical field of machine tool tool clamping, and specifically to an FMS flexible line adaptive central tool magazine system and method. Background Art

[0002] In modern manufacturing, the flexible manufacturing system (FMS) has become a key technology for improving production efficiency and adaptability due to its high flexibility and automation level. As one of the core components of the FMS, the configuration and management of the central tool magazine directly affect the efficiency and stability of the production line. With the variability of market demands and the shortening of product life cycles, enterprises are facing increasing pressure to maintain production flexibility while ensuring production efficiency and quality. Therefore, studying the configuration and management strategies of the central tool magazine on the FMS line can not only optimize the production process, reduce production costs, but also improve the ability to respond to market changes, which is of great significance for enhancing the core competitiveness of enterprises.

[0003] The central tool magazine plays a crucial role in the flexible manufacturing system (FMS). It is a bridge connecting the processing tasks and the machine tool execution. The main functions of the central tool magazine are to store, manage, and distribute various tools to ensure that the processing system can seamlessly perform diverse and complex machining operations. Through the central tool magazine, the machine tool can quickly replace the required tools according to the processing needs, effectively reducing the non-production time of the machine tool and enhancing the continuity and flexibility of production. The configuration management strategy of the central tool magazine has a decisive impact on maintaining production efficiency and machining accuracy. It automatically allocates tools through a preset program, enabling dynamic optimization according to the processing sequence and tool wear during the production process. This not only ensures the machining quality but also extends the service life of the tools. When dealing with production orders of multiple varieties and small batches, the central tool magazine can provide a quick response to meet the needs of customization and just-in-time production. In addition, the intelligent management of the central tool magazine is also the key to improving the efficiency of the FMS. It can exchange information with the upper-level manufacturing execution system (MES) and enterprise resource planning system (ERP), etc., to achieve real-time monitoring and analysis of tool usage data and provide data support for production decisions.

[0004] The FMS flexible line adaptive central tool magazine system is designed to accommodate the replacement and installation of multiple tool holders during the workpiece machining process. A buffer table is provided on the robotic arm of the FMS flexible line adaptive central tool magazine system for temporarily storing the removed tool holders to achieve continuous multi-station tool change operations. However, the state of the tool holders placed on the buffer table cannot be adaptively adjusted and controlled according to the subsequent installation requirements. During the subsequent process of the robotic arm gripping and installing the tool holders, the state of the tool holders needs to be re-identified and adjusted, which reduces the tool change efficiency. Moreover, after tool change, in order to facilitate the direct storage and use of the subsequent tool holders, the tool holders need to be cleaned. Especially for Morse taper tool holders, during the cleaning process, since the positioning surface of the tool holder is conical and the conical surface mainly assists in subsequent positioning and installation, special attention needs to be paid to the cleaning process. When using the blowing method to directly blow and clean, it is difficult for the cleaning air flow direction to be consistent with the normal line of the conical surface of the tool holder, and a direct and efficient impact force cannot be formed, affecting the cleaning effect of the tool holder. Therefore, we propose an FMS flexible line adaptive central tool magazine system and method. Summary of the Invention

[0022] An operation method of an FMS flexible line adaptive central tool magazine includes the following steps:

[0023] S1: During the tool changing operation of the workpiece in the FMS flexible line adaptive central tool magazine, through the driving action of the driving assembly, the sliding table moves on the operating table. During the movement of the sliding table, through the driving action of the clamping assembly on the tool changing robot arm, the tool shank that needs to be installed and used inside the central tool magazine is pushed towards the slot of the strip-shaped rack. During the pushing process, the positioning seat of the tool shank is clamped between the strip-shaped rack and the arc-shaped pressing plate. Through the pressure generated during the counteracting and clamping process of the arc-shaped pressing plate, the pushed tool shank is limited.

[0024] S2: During the fixing of pushing the tool shank towards the strip-shaped rack and clamping and limiting it, the block-shaped positioning plate and the L-shaped positioning plate are placed inside the positioning slot of the tool shank. After clamping the tool shank, through the transmission assembly, the first sliding plate and the second sliding plate are forced to move closer to each other. During the movement process, the block-shaped positioning plate and the L-shaped positioning plate are driven to move synchronously. During the movement of the block-shaped positioning plate and the L-shaped positioning plate, the block-shaped positioning plate and the L-shaped positioning plate are in contact with the two opposite inner walls of the tool shank positioning slot. During the contact process, an adaptive positioning operation of the clamped tool shank is performed. Through the adaptive positioning operation of the tool shank, it is convenient to directly clamp and install the tool shank subsequently, without the need to perform repeated adjustment operations in combination with the state of the tool shank after clamping, improving the efficiency of tool installation and replacement.

[0025] S3: After the tool shank that needs to be installed and used is placed and limited on the buffer table, through the movement of the sliding table and the driving of the tool changing robot arm, the tool shank to be used is installed at the specified position and the used tool shank after disassembly is limited and fixed on the buffer table.

[0026] S4: During the whole process, through the mutual cooperation of the sliding table, the tool changing robot arm, the central tool magazine and the buffer table, there is no need to wait for the tool magazine to reposition. This asynchronous operation reduces the idling time of the machine tool spindle. Through the prefetch function of the buffer table, the tool changing efficiency for workpiece processing can be significantly improved;

[0027] S5: After the handle limit of the disassembled and used tool holder is fixed on the buffer table, in order to ensure that the tool holder can be used continuously in the future, it is necessary to clean the outer side of the tool holder. During the cleaning process, through the lifting component, the installation cylinder is driven to move towards the disassembled and used tool holder, so that the installation cylinder is sleeved on the outer side of the disassembled and used tool holder;

[0028] S6: During the downward movement of the installation cylinder, through the connection of the rotation component, the adjustment component and the telescopic component, the operation board is driven to move downward. During the downward movement of the operation board, the front end of the adaptive pin on one side of the operation board in the lower position abuts against the installation taper surface of the tool holder. During the abutting process, along with the continuous downward movement of the operation board and the rotatable connection between the fixed block and the connecting block, the operation board tilts and deflects. During the tilting and deflecting process, through the elastic extrusion of the spring on the telescopic component on the operation board during the movement process, the front end of the adaptive pin on the operation board in the lower position remains in contact with the installation taper surface as the downward movement progresses, and through the tilting rotation of the operation board, the front end of the adaptive pin on the operation board in the upper position abuts against the installation taper surface of the tool holder, realizing the adjustment of the use angle of the operation board according to the state of the tool holder installation taper surface;

[0029] S7: After the adjustment, the use angle of the operation board is perpendicular to the normal of the tool holder taper surface. Further, the air outlet of the rectangular air hood on the operation board is kept consistent with the normal of the tool holder taper surface. After the adjustment is completed, through the rotation component, the rotating disk rotates. During the rotation of the rotating disk, through the connection of the adjustment component and the telescopic component, the operation board is driven to rotate inside the installation cylinder. During the rotation process, through the driving action of the air pump and the connection of the air pipe, the gas is blown from the rectangular air hood and the air outlet towards the installation taper surface of the tool holder. Because the use angle of the operation board is perpendicular to the normal of the tool holder taper surface, during the blowing and cleaning process, the cleaning air flow direction is kept consistent with the normal of the tool holder taper surface, which can form a direct and efficient impact force. Compared with inclined or parallel blowing, the vertical direction can more effectively peel off the debris adhering in the pits or gaps of the taper surface, improving the cleaning efficiency. And the Morse taper surface is a conical structure, and vertical blowing can make the air flow diffuse symmetrically, evenly covering the entire taper surface, avoiding local cleaning blind spots caused by blowing angle deviation. Vertical blowing can ensure that there is no residue of debris, guarantee the cleaning effect of the tool holder, and is more convenient for the subsequent high-quality tool changing operation of the tool holder.

[0030] Compared with the prior art, the beneficial effects of the present invention are:

[0031] 1. In the process of tool changing operation of the FMS flexible line adaptive central tool magazine workpiece of the present invention, through the cooperation between the slide table, the tool changing robot arm and the central tool magazine and the tool changing robot arm, there is no need to wait for the tool magazine to be repositioned. This asynchronous operation reduces the idling time of the machine tool spindle. Especially in the scenario of multi-tasking parallel of the FMS line, the pre-fetching function of the cache table can significantly improve the tool changing efficiency for workpiece processing. After the tool handle is cached and placed on the cache table, the adaptive positioning component is used to perform adaptive positioning operation on the clamped tool handle. Through the adaptive positioning operation on the tool handle, it is convenient to clamp and install the tool handle directly in the future, and there is no need to perform repeated adjustment operations based on the state of the tool handle after clamping, thereby improving the efficiency of tool installation and replacement;

[0032] 2. The invented FMS flexible line adaptive central tool magazine cleans the tool holder after tool change during workpiece processing. Through transmission, the direction of the cleaning airflow during the air blowing cleaning process is consistent with the normal line of the tool holder cone surface, which can form a direct and efficient impact force. Compared with inclined or parallel air blowing, the vertical direction can more effectively peel off the debris adhering to the pits or gaps on the cone surface, thereby improving the cleaning efficiency. The Morse cone surface is a conical structure, and vertical air blowing can make the airflow diffuse in a symmetrical manner, evenly covering the entire cone surface, avoiding local cleaning blind spots caused by deviation in the blowing angle, especially in the key area where the cone surface and the spindle are closely matched. Vertical air blowing can ensure that there is no debris residue, ensure the cleaning effect of the tool holder, and facilitate subsequent high-quality tool change operations of the tool holder.

Embodiment 1

[0049] Please refer to Figures 1 - 14 , the FMS flexible line adaptive central tool magazine system shown in the figure includes:

[0050] The central tool magazine 101 is used for storing tool holders and positioning and placing the stored tool holders through an internal positioning frame;

[0051] It should be noted here that the central tool magazine 101 is a conventional technical component in the technical field of this application. Its working principle and operation method are regarded as prior art in this application and will not be elaborated here;

[0052] It is worth noting here that the tool holders targeted in this application include a tool body, a positioning seat, a positioning groove, and a mounting taper surface. The positioning seat, positioning groove, and mounting taper surface are used for positioning and installing the tool body during the installation process. Among them, the tool body, positioning seat, positioning groove, and mounting taper surface are conventional components on the tool holder, and their working principle and operation method will not be further elaborated in this application;

[0053] The tool changing robot arm 102 is used for grasping and placing tool holders. A clamping component for clamping the tool holder is arranged on the tool changing robot arm 102, and the tool changing robot arm 102 drives the clamping and loosening of the tool holder through the clamping component to realize the tool changing operation;

[0054] It should be noted here that the tool changing robot arm 102 and the clamping component on the tool changing robot arm 102 are conventional technical components in the technical field of this application. Their working principle and operation method are regarded as prior art in this application and will not be elaborated here;

[0055] The buffer table 103 is used for carrying and placing the tool holders after tool changing and the tool holders to be installed during tool changing;

[0056] And an operation table 2. The central tool magazine 101 is arranged on the operation table 2. A sliding table 3 is slidably connected to the operation table 2 through a slide rail. A driving component for assisting the sliding of the sliding table 3 is arranged between the sliding table 3 and the operation table 2. A clamping component for clamping and limiting the tool holder during the tool holder buffering process and an adaptive positioning component for adaptively positioning the state of the tool holder after clamping are arranged on the buffer table 103. An installation cylinder 6 is arranged on the buffer table 103. A lifting component for assisting the lifting of the installation cylinder 6 is arranged between the installation cylinder 6 and the buffer table 103. A cleaning component for cleaning the mounting taper surface of the tool holder and an adjusting component for adjusting the angle of the cleaning component according to the taper of the mounting taper surface of the tool holder are arranged inside the installation cylinder 6;

[0057] It should be noted here that: during the tool changing operation of the FMS flexible line adaptive central tool magazine workpiece, the slide 3, the tool changing robot 102 and the central tool magazine 101 and the tool changing robot 102 cooperate with each other, and there is no need to wait for the tool magazine to be repositioned.

Through the adaptive positioning operation on the tool handle, it is convenient to clamp and install the tool handle directly in the future, and there is no need to perform repeated adjustment operations based on the state of the tool handle after clamping, thereby improving the efficiency of tool installation and replacement;

[0058] When cleaning the tool holder after tool change, the direction of the cleaning airflow is kept consistent with the normal line of the tool holder cone surface through transmission during the air blowing cleaning process, which can form a direct and efficient impact force.

Moreover, the Morse cone surface is a conical structure, and vertical air blowing can make the airflow diffuse in a symmetrical manner, evenly covering the entire cone surface, avoiding local cleaning blind spots caused by deviation of the air blowing angle, especially in the key area where the cone surface and the spindle are closely matched. Vertical air blowing can ensure that there is no debris left, ensure the cleaning effect of the tool holder, and facilitate the subsequent high-quality tool change operation of the tool holder.

[0059] It is worth noting here that: the present application is mainly aimed at cleaning the cone surface of the tool handle installation, while other positions can be cleaned directly by blowing air, which is regarded as the prior art in the present application and will not be elaborated in detail here.

[0072] It should be explained here that: when driving the first slide plate 1201 and the second slide plate 1202 to move closer to each other to adaptively adjust the state of the tool handle, the two groups of limiting plates 1301 are driven to move synchronously towards the outer side of the tool handle. During the movement, the arc-shaped grooves 1302 of the two groups of limiting plates 1301 abut against the outer side of the tool handle.

The two ends of the spring 1003 are respectively connected to the connecting frame 901 and the installation plate 902;

[0080] It should be noted here that: through the multiple sets of sleeves 1001 and the sliding rod 1002, it is convenient to assist the telescopic connection between the connecting frame 901 and the installation plate 902.

[0086] It should be noted here that: through the driving effect of the cylinder 701 and the connection effect of the rectangular block 702, it is convenient to assist the lifting of the installation cylinder 6.

[0087] In this solution: an operation method of an FMS flexible line adaptive central tool magazine includes the following steps:

[0088] S1: During the tool change operation of the workpiece of the FMS flexible line adaptive central tool magazine, through the driving effect of the driving assembly, the sliding table 3 moves on the operation table 2. During the movement of the sliding table 3, through the driving effect of the clamping assembly on the tool change robot arm 102, the tool shank that needs to be installed and used inside the central tool magazine 101 is pushed towards the slot 502 of the strip-shaped rack 501. During the pushing process, the positioning seat of the tool shank is caught between the strip-shaped rack 501 and the arc-shaped pressing plate 504. Through the pressure generated during the abutting and catching process of the arc-shaped pressing plate 504, the pushed tool shank is limited;

[0089] S2: During the fixing of pushing and clamping and limiting the tool shank towards the strip-shaped rack 501, the block-shaped positioning plate 1203 and the L-shaped positioning plate 1204 are placed inside the positioning groove of the tool shank. After clamping the tool shank, through the transmission assembly, the first sliding plate 1201 and the second sliding plate 1202 are forced to move closer to each other. During the movement process, the block-shaped positioning plate 1203 and the L-shaped positioning plate 1204 move synchronously. During the movement of the block-shaped positioning plate 1203 and the L-shaped positioning plate 1204, the block-shaped positioning plate 1203 and the L-shaped positioning plate 1204 abut against the two opposite inner walls of the tool shank positioning groove. During the abutting process, an adaptive positioning operation is performed on the clamped tool shank (see Figure 9 ), through the adaptive positioning operation of the tool shank, it is convenient to directly clamp and install the tool shank subsequently, without the need to perform repeated adjustment operations in combination with the state of the tool shank after clamping, improving the efficiency of tool installation and replacement;

[0090] S3: After the tool holder to be installed and used is placed in a limited position on the buffer table 103, through the movement of the sliding table 3 and the drive of the tool change robot arm 102, the tool holder to be used is installed at the specified position, and the tool holder after disassembly and use is limited and fixed on the buffer table 103;

[0091] S4: During the whole process, through the mutual cooperation of the sliding table 3, the tool change robot arm 102, the central tool magazine 101 and the buffer table 103, there is no need to wait for the tool magazine to reposition. This asynchronous operation reduces the idle running time of the machine tool spindle. Through the prefetch function of the buffer table 103, the tool change efficiency for workpiece processing can be significantly improved;

[0092] S5: After the tool holder after disassembly and use is limited and fixed on the buffer table 103, in order to ensure that the tool holder can be used continuously later, it is necessary to clean the outer side of the tool holder. During the cleaning process, through the lifting component, the installation cylinder 6 is driven to move towards the tool holder after disassembly and use, so that the installation cylinder 6 is sleeved on the outer side of the tool holder after disassembly and use;

[0093] S6: During the descending process of the installation cylinder 6, through the connection of the rotation component, the adjustment component and the telescopic component, the operation plate 801 is driven to descend. During the descending process of the operation plate 801, the front end of the adaptive pin 905 on one side of the operation plate 801 at the lower position abuts against the installation taper surface of the tool holder. During the abutting process, along with the continuous descent of the operation plate 801 and the rotatable connection between the fixed block 903 and the connecting block 904, the operation plate 801 tilts and deflects. During the tilting and deflecting process, through the elastic extrusion of the spring 1003 on the telescopic component on the operation plate 801 during the movement process, the front end of the adaptive pin 905 on the operation plate 801 at the lower position keeps abutting against the installation taper surface as the descent progresses, and through the tilting rotation of the operation plate 801, the front end of the adaptive pin 905 on the operation plate 801 at the upper position abuts against the installation taper surface of the tool holder (see Figure 10 status), realizing the adjustment of the use angle of the operation plate 801 according to the state of the tool holder installation taper surface;

[0094] S7: After adjustment, the usage angle of the operation panel 801 is perpendicular to the normal of the tool shank taper surface. Further, the air outlet 803 of the rectangular air hood 802 on the operation panel 801 is made to be consistent with the normal of the tool shank taper surface. After the adjustment is completed, the rotating disk 1101 is rotated through the rotating assembly. During the rotation of the rotating disk 1101, through the connection of the adjustment assembly and the telescopic assembly, the operation panel 801 is driven to rotate inside the mounting cylinder 6. During the rotation, through the driving action of the air pump 805 and the connection of the air pipe 804, gas is blown from the rectangular air hood 802 and the air outlet 803 towards the mounting taper surface of the tool shank. Since the usage angle of the operation panel 801 is perpendicular to the normal of the tool shank taper surface, the cleaning air flow direction is consistent with the normal of the tool shank taper surface during the blowing and cleaning process, which can form a direct and efficient impact force. Compared with inclined or parallel blowing, the vertical direction can more effectively peel off the debris adhering in the pits or gaps of the taper surface, improving the cleaning efficiency. Moreover, the Morse taper surface is a conical structure, and vertical blowing can make the air flow diffuse symmetrically, evenly covering the entire taper surface, avoiding local cleaning blind spots caused by blowing angle deviation. Vertical blowing can ensure that there is no residue of debris, guarantee the cleaning effect of the tool shank, and is more convenient for the subsequent high-quality tool change operation of the tool shank.

During the pushing process, the positioning seat of the tool shank is clamped between the strip-shaped rack (501) and the arc-shaped pressing plate (504). Through the pressure generated during the counteracting and clamping process of the arc-shaped pressing plate (504), the pushed tool shank is limited; S2: When the tool shank is pushed towards the strip-shaped rack (501) and clamped and limited, the block-shaped positioning plate (1203) and the L-shaped positioning plate (1204) are placed inside the positioning slot of the tool shank.
