Description

Technical Field

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

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

[0003] The central tool magazine plays a vital role in the flexible manufacturing system (FMS). It is a bridge connecting the processing tasks and the execution of machine tools. The main function of the central tool magazine is to store, manage and distribute various types of tools to ensure that the processing system can seamlessly perform diversified and complex processing operations. Through the central tool magazine, the machine tool can quickly replace the required tools according to the processing requirements, thereby effectively reducing the non-productive time of the machine tool and improving the continuity and flexibility of production. The configuration management strategy of the central tool magazine has a decisive influence on maintaining production efficiency and processing accuracy. It automatically allocates tools through preset programs, so that it can be dynamically optimized according to the processing sequence and tool wear during the production process, which not only ensures the processing quality, but also extends the service life of the tool. When processing multi-variety and small-batch production orders, the central tool magazine can provide rapid 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 FMS. It can exchange information with the upper-level manufacturing execution system (MES) and enterprise resource planning system (ERP), etc., to realize real-time monitoring and analysis of tool usage data, and provide data support for production decisions.

[0004] In order to adapt to the replacement and installation of multiple sets of tool holders during workpiece processing, the FMS flexible line adaptive central tool magazine system is equipped with a cache table on the robot arm of the FMS flexible line adaptive central tool magazine system, which is used to temporarily store the disassembled tool holders to realize continuous multi-station tool change operations. However, the state of the tool holder placed on the cache table cannot be adaptively adjusted and controlled according to the needs of subsequent installation. In the subsequent process of the robot arm clamping and installing the tool holder, the state of the tool holder needs to be re-identified and adjusted, which reduces the efficiency of tool change. After the tool change, in order to facilitate the direct storage and use of the subsequent tool holders, the tool holder needs 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, it is necessary to focus on cleaning. When using air blowing to directly perform air cleaning, the direction of the cleaning airflow is difficult to be consistent with the normal line of the tool holder cone surface, and a direct and efficient impact force cannot be formed, which affects the cleaning effect of the tool holder. For this reason, we propose an FMS flexible line adaptive central tool magazine system and method. Summary of the invention

[0015] An operating method for an FMS flexible line adaptive central tool magazine comprises the following steps: S1: During the tool changing operation of the FMS flexible line adaptive central tool magazine workpiece, the slide moves on the operating table through the driving action of the driving component. During the movement of the slide, the tool handle to be installed in the central tool magazine is pushed toward the slot of the strip frame through the driving action of the clamping component on the tool changing robot arm. During the pushing process, the positioning seat of the tool handle is inserted between the strip frame and the arc pressure plate. The pressure generated by the arc pressure plate during the mutual insertion process limits the inserted tool handle. S2: When the tool handle is pushed toward the strip frame and clamped to a limited position, the block positioning plate and the L-shaped positioning plate are placed inside the positioning groove of the tool handle. After the tool handle is clamped, the first slide plate and the second slide plate are forced to move toward each other through the transmission component. During the movement, the block positioning plate and the L-shaped positioning plate are driven to move synchronously. During the movement of the block positioning plate and the L-shaped positioning plate, the two sets of inner walls of the tool handle positioning groove opposite to each other are abutted. During the abutment, the clamped tool handle is adaptively positioned. Through the adaptive positioning operation of 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. S3: After the tool holder to be installed is placed on the buffer table, the tool holder to be used is installed at the designated position and the tool holder after disassembly is fixed on the buffer table by moving the slide table and driving the tool changing robot arm; S4: During the whole process, the slide table, tool changing robot arm, central tool magazine and tool changing robot arm cooperate with each other, and 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 operation of the FMS line, the pre-fetching function of the cache table can significantly improve the tool changing efficiency for workpiece processing. S5: After the disassembled and used tool handle is fixed on the buffer table, in order to ensure that the tool handle can be used continuously, the outer side of the tool handle needs to be cleaned. During the cleaning process, the installation cylinder is driven to move toward the disassembled and used tool handle through the lifting assembly, so that the installation cylinder is sleeved on the outer side of the disassembled and used tool handle; S6: During the descent of the mounting tube, the operating panel is driven to move downward through the connection between the rotating assembly, the adjusting assembly and the telescopic assembly. During the descent of the operating panel, the front end of the adaptive pin at the lower position on one side of the operating panel is abutted against the mounting conical surface of the tool handle. During the abutment process, the operating panel continues to descend and the rotatable connection between the fixed block and the connecting block causes the operating panel to tilt and deflect. During the tilt and deflection process, the elastic force of the spring on the telescopic assembly squeezes the operating panel during movement, so that the front end of the adaptive pin at the lower position of the operating panel is kept against the mounting conical surface as the descent proceeds, and the front end of the adaptive pin at the upper position of the operating panel is abutted against the mounting conical surface of the tool handle through the tilting and rotation of the operating panel, thereby adjusting the use angle of the operating panel according to the state of the mounting conical surface of the tool handle. S7: After adjustment, the use angle of the operating panel is perpendicular to the normal of the cone surface of the tool handle, and the air outlet of the rectangular air hood on the operating panel is further kept consistent with the normal of the cone surface of the tool handle. After the adjustment is completed, the rotating disk is rotated by the rotating component. During the rotation of the rotating disk, the operating panel is driven to rotate inside the mounting tube through the connection of the adjusting component and the telescopic component. During the rotation, the gas is blown out from the rectangular air hood and the air outlet toward the mounting cone surface of the tool handle through the driving action of the air pump and the connection action of the air pipe. Because the use angle of the operating panel is perpendicular to the normal of the cone surface of the tool handle, the blowing During the cleaning process, the direction of the cleaning airflow is consistent with the normal of the cone surface of the tool holder, which can form a direct and efficient impact force. Compared with oblique or parallel 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. Moreover, the Morse cone surface is a conical structure. Vertical 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 blowing can ensure that there is no debris residue, ensure the cleaning effect of the tool holder, and facilitate the subsequent high-quality tool changing operation of the tool holder.

[0016] Compared with the prior art, the present invention has the following beneficial effects: 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; 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.

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; 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. Compared with oblique 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. 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. 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.

The arc-shaped pressing plate 504 is made of a tough metal material (such as carbon steel) and can generate pressure after being pressed against each other. The arc-shaped pressing plate 504 is connected and fixed to the strip frame 501 via a mounting frame 503; It should be noted here that: the removed tool handle is pushed toward the inside of the slot 502 of the strip frame 501 by the tool changing robot arm 102.

During the movement, the arc grooves 1302 of the two sets of limit plates 1301 are abutted against the outside of the tool handle. Through the abutment effect, the tool handle after adaptive adjustment is limited by abutment, so as to maintain the state after adaptive adjustment.

During the downward movement of the operating plate 801, the front end of the adaptive pin 905 at the lower position on one side of the operating plate 801 is abutted against the mounting cone surface of the tool handle. During the abutment process, with the continued descent of the operating plate 801 and the rotatable connection between the fixed block 903 and the connecting block 904, the operating plate 801 is tilted and deflected. During the tilting and deflecting process, through the elastic squeezing effect of the spring 1003 on the telescopic component on the operating plate 801 during the movement, the front end of the adaptive pin 905 at the lower position of the operating plate 801 is kept against the mounting cone surface as the descent proceeds, and through the tilting and rotation of the operating plate 801, the front end of the adaptive pin 905 at the upper position on the operating plate 801 is abutted against the mounting cone surface of the tool handle, thereby realizing the adjustment of the use angle of the operating plate 801 according to the state of the mounting cone surface of the tool handle.

[0032] In this scheme: an operation method of an FMS flexible line adaptive central tool magazine includes the following steps: S1: During the tool changing operation of the FMS flexible line adaptive central tool magazine workpiece, the slide 3 is moved on the operating table 2 through the driving action of the driving component. During the movement of the slide 3, the tool handle to be installed in the central tool magazine 101 is pushed toward the inside of the card slot 502 of the strip frame 501 through the driving action of the clamping component on the tool changing robot arm 102. During the pushing process, the positioning seat of the tool handle is inserted between the strip frame 501 and the arc pressure plate 504. The pressure generated by the arc pressure plate 504 during the mutual insertion process limits the inserted tool handle. S2: When the tool handle is pushed toward the strip frame 501 and clamped to limit the fixation, the block positioning plate 1203 and the L-shaped positioning plate 1204 are placed inside the positioning groove of the tool handle. After the tool handle is clamped, the first slide plate 1201 and the second slide plate 1202 are forced to move towards each other through the transmission component. During the movement, the block positioning plate 1203 and the L-shaped positioning plate 1204 are driven to move synchronously. During the movement of the block positioning plate 1203 and the L-shaped positioning plate 1204, the block positioning plate 1203 and the L-shaped positioning plate 1204 are abutted against the two sets of inner walls of the tool handle positioning groove. During the abutment, the clamped tool handle is adaptively positioned (see Fig. 9 ), through the adaptive positioning operation of the tool holder, it is convenient to clamp the tool holder directly and install it directly, without the need to repeat the adjustment operation based on the state of the tool holder after clamping, thus improving the efficiency of tool installation and replacement; S3: After the tool handle to be installed and used is placed at the upper limit position on the buffer table 103, the tool handle to be used is installed at the specified position through the movement of the slide table 3 and the driving of the tool changing robot arm 102, and the tool handle after disassembly and use is fixed on the buffer table 103; S4: During the whole process, the slide table 3, the tool changing robot arm 102 cooperate with the central tool magazine 101 and the tool changing robot arm 102, and 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-task parallel operation of the FMS line. The pre-fetching function of the cache table 103 can significantly improve the tool changing efficiency for workpiece processing. S5: After the disassembled and used knife handle is fixed on the buffer table 103, in order to ensure that the subsequent knife handle can continue to be used, the outer side of the knife handle needs to be cleaned. During the cleaning process, the installation tube 6 is driven to move toward the disassembled and used knife handle through the lifting assembly, so that the installation tube 6 is sleeved on the outer side of the disassembled and used knife handle; S6: During the descent of the mounting tube 6, the operating plate 801 is driven to move downward through the connection between the rotating assembly, the adjusting assembly and the telescopic assembly. During the descent of the operating plate 801, the front end of the adaptive pin 905 at the lower position on one side of the operating plate 801 is abutted against the mounting conical surface of the tool handle. During the abutment process, along with the continued descent of the operating plate 801 and the rotatable connection between the fixed block 903 and the connecting block 904, the operating plate 801 is tilted and deflected. During the tilting and deflecting process, the elastic force of the spring 1003 on the telescopic assembly squeezes the operating plate 801 during the movement, so that the front end of the adaptive pin 905 at the lower position of the operating plate 801 is kept against the mounting conical surface as the descent proceeds, and through the tilting and rotation of the operating plate 801, the front end of the adaptive pin 905 at the upper position on the operating plate 801 is abutted against the mounting conical surface of the tool handle (see FIG. 2 ). Fig.10state), so as to adjust the use angle of the operating panel 801 according to the state of the tool holder mounting cone surface; S7: After adjustment, the use angle of the operating plate 801 is perpendicular to the normal line of the cone surface of the tool handle, and the air outlet 803 of the rectangular air cover 802 on the operating plate 801 is further made consistent with the normal line of the cone surface of the tool handle. After the adjustment is completed, the rotating disk 1101 is rotated by the rotating assembly. During the rotation of the rotating disk 1101, the operating plate 801 is driven to rotate inside the mounting tube 6 through the connection between the adjusting assembly and the telescopic assembly. During the rotation, the gas is blown out from the rectangular air cover 802 and the air outlet 803 toward the mounting cone surface of the tool handle through the driving action of the air pump 805 and the connection action of the air pipe 804. The use angle of 1 is perpendicular to the normal of the cone surface of the tool holder, so that the direction of the cleaning airflow during the air blowing cleaning process is consistent with the normal of the cone surface of the tool holder, which can form a direct and efficient impact force. Compared with oblique or parallel 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. Moreover, the Morse cone surface is a conical structure. Vertical blowing can make the airflow diffuse in a symmetrical manner and evenly cover the entire cone surface, avoiding local cleaning blind spots caused by deviation of the blowing angle, especially in the key area where the cone surface and the spindle are closely matched. Vertical blowing can ensure that there is no debris residue, ensure the cleaning effect of the tool holder, and facilitate the subsequent high-quality tool change operation of the tool holder.

During the movement of the slide (3), the tool handle to be installed in the central tool magazine (101) is pushed toward the inside of the card slot (502) of the strip frame (501) by the driving action of the clamping component on the tool changing robot arm (102). During the pushing process, the positioning seat of the tool handle is inserted between the strip frame (501) and the arc pressure plate (504). The tool handle is limited by the pressure generated by the arc pressure plate (504) during the mutual insertion process. S2: When the tool handle is pushed toward the strip frame (501) and clamped to a limited position, the block positioning plate (1203) and the L-shaped positioning plate (1204) are located inside the positioning groove of the tool handle. After the tool handle is clamped, the first slide plate (1201) and the second slide plate (1202) are forced to move toward each other through the transmission component. During the movement, the block positioning plate (1203) and the L-shaped positioning plate (1204) are driven to move synchronously. During the movement of the block positioning plate (1203) and the L-shaped positioning plate (1204), the block positioning plate (1203) and the L-shaped positioning plate (1204) are abutted against two sets of inner walls of the tool handle positioning groove. During the abutment, the clamped tool handle is adaptively positioned. The adaptive positioning operation of the tool handle facilitates the subsequent direct clamping and installation of the tool handle, and there is no need to perform repeated adjustment operations based on the state of the clamped tool handle, thereby improving the efficiency of tool installation and replacement. S3: After the tool handle to be installed and used is placed at the upper limit position on the buffer table (103), the tool handle to be used is installed at a designated position by moving the slide table (3) in coordination with the driving of the tool changing robot arm (102), and the tool handle after being disassembled and used is fixed at the upper limit position on the buffer table (103); S4: During the whole process, the slide table (3), the tool changing robot arm (102), the central tool magazine (101) and the tool changing robot arm (102) cooperate with each other, and there is no need to wait for the tool magazine to be repositioned. This asynchronous operation reduces the idle time of the machine tool spindle. Especially in the scenario of multi-tasking parallel operation of the FMS line, the pre-fetching function of the cache table (103) can significantly improve the tool changing efficiency for workpiece processing; S5: After the disassembled and used knife handle is fixed on the buffer table (103), in order to ensure that the knife handle can be used continuously, the outer side of the knife handle needs to be cleaned. During the cleaning process, the installation cylinder (6) is driven to move toward the disassembled and used knife handle through the lifting assembly, so that the installation cylinder (6) is sleeved on the outer side of the disassembled and used knife handle; S6: During the process of the installation cylinder (6) descending, the operation plate (801) is driven to move downward through the connection of the rotating assembly, the adjusting assembly and the telescopic assembly. During the process of the operation plate (801) descending, the front end of the adaptive pin (905) at the lower position on one side of the operation plate (801) is abutted against the installation conical surface of the tool handle. During the abutment process, the operation plate (801) continues to descend and the rotatable connection between the fixed block (903) and the connecting block (904) causes the operation plate (801) to tilt and deflect. During the tilting and deflecting process, the spring (1003) on the telescopic assembly exerts an elastic force on the operating plate (801) during the movement, so that the front end of the adaptive pin (905) at the lower position of the operating plate (801) is kept against the mounting conical surface as it descends, and the front end of the adaptive pin (905) at the upper position of the operating plate (801) is made to abut against the mounting conical surface of the tool handle through the tilting and rotation of the operating plate (801), thereby achieving adjustment of the use angle of the operating plate (801) according to the state of the mounting conical surface of the tool handle; S7: After adjustment, the use angle of the operating panel (801) is perpendicular to the normal of the cone surface of the tool handle, and the air outlet (803) of the rectangular air cover (802) on the operating panel (801) is further aligned with the normal of the cone surface of the tool handle. After the adjustment is completed, the rotating disk (1101) is rotated by the rotating assembly. During the rotation of the rotating disk (1101), the operating panel (801) is driven to rotate inside the mounting tube (6) through the connection of the adjusting assembly and the telescopic assembly. During the rotation, the gas is driven from the rectangular air cover (802) and the air outlet (803) toward the mounting of the tool handle through the driving action of the air pump (805) and the connection action of the air pipe (804). Conical surface blowing, because the use angle of the operating panel (801) is perpendicular to the normal of the tool holder conical surface, the direction of the cleaning airflow during the air blowing cleaning process is consistent with the normal of the tool holder conical 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 to the pits or gaps on the conical surface, thereby improving the cleaning efficiency. Moreover, the Morse cone surface is a conical structure, and vertical blowing can make the airflow diffuse in a symmetrical manner, evenly covering the entire cone surface, avoiding local cleaning blind spots caused by deviations in the blowing angle, especially in the key area where the cone surface and the spindle are closely matched. Vertical blowing can ensure that there is no debris residue, ensure the cleaning effect of the tool holder, and facilitate subsequent high-quality tool changing operations of the tool holder.
