Description

Technical Field

[0001] This invention relates to the field of multi-variety precision intelligent tool management technology, specifically a workshop management system based on intelligent tool holders. Background Technology

[0002] The production of complex components is a typical example of multi-process, small-batch processing. Various types of precision CNC tools need to adapt to the variable working conditions of manufacturing environments with complex processing characteristics, numerous processes, and long cycles. Under current working conditions, tool status information is only reflected by the tool usage time monitored by the CNC system, which is difficult to meet the national requirements for digitalization, intelligence, and green development. With the development of sensing technology, multi-source data information monitoring has become popular among manufacturing enterprises.

[0003] Benchtop force gauges and wireless vibration platforms are widely used in laboratory environments due to their ease of installation. However, in the future, manufacturing will move towards unmanned smart factories, requiring real-time feedback of processing information. Intelligent toolholders, with their superior integration, interchangeability, and suitability for surface machining, are being applied in high-value-added component manufacturing fields such as aerospace and weaponry. As an end effector, the intelligent toolholder can monitor multi-source data such as force, vibration, and temperature in real time during machining, and can operate in parallel with CNC systems to improve tool life monitoring. For multi-process manufacturing and the use of various tool types, research on workshop management systems based on intelligent toolholders is urgently needed. Summary of the Invention

[0004] The purpose of this invention is to provide a workshop management system based on intelligent tool holders, including an intelligent tool holder call management module, an adaptive power supply management module, an adaptive power failure management module, an intelligent tool holder charging management module, an intelligent tool holder power indicator management and automatic charging control module, an intelligent tool holder-based tool life management module, a multi-machine tool collaborative intelligent tool holder management module, and a data acquisition module.

[0005] The intelligent tool holder recall management module recalls different intelligent tool holders based on the CNC program and virtual machining time sent from the cloud.

[0006] When the smart tool holder is invoked, the corresponding adaptive power supply management module of the smart tool holder works to supply power to the smart tool holder and the corresponding data acquisition module;

[0007] When the smart tool holder returns to the tool magazine and pauses operation, the adaptive power-off management module corresponding to the smart tool holder activates, causing the smart tool holder to lose power and shutting down the data acquisition module;

[0008] The data acquisition module records the power-on duration of the corresponding smart tool holder, collects the working data of the smart tool holder, and transmits it to the tool life management module based on the smart tool holder.

[0009] The intelligent tool holder charging management module is used to charge the intelligent tool holder;

[0010] The intelligent tool holder power indicator light management and automatic charging control module is used to adjust the power indicator light on the intelligent tool holder and control the intelligent tool holder that needs to be charged to return to the tool magazine for automatic charging.

[0011] The tool life management module based on the smart tool holder determines whether the current usage time of the smart tool holder exceeds the tool life setting time. If so, it determines whether the working data of the smart tool holder exceeds the set threshold. If so, it performs a tool replacement operation on the smart tool holder.

[0012] The multi-machine tool collaborative intelligent tool holder management module is used to install one or more intelligent tool holders on different machine tool spindles.

[0013] Furthermore, it also includes an intelligent toolholder experience-based replacement management module;

[0014] Before processing, the cloud receives the current material, tool and cutting parameters and compares them in the database. If there is data that is the same as the current material, tool and cutting parameters, it sends a smart tool holder call signal to the smart tool holder experience law replacement management module. Otherwise, it sends a regular tool holder call signal to the smart tool holder experience law replacement management module.

[0015] After receiving the intelligent tool holder call signal, the intelligent tool holder experience rule replacement management module controls the intelligent tool holder call management module to call the intelligent tool holder.

[0016] During the operation of the intelligent tool holder, the data acquisition module uploads the current material, tool, cutting parameters and intelligent tool holder working data to the cloud database for storage;

[0017] After receiving a regular tool holder call signal, the intelligent tool holder experience rule replacement management module controls the intelligent tool holder call management module to call other tool holders besides the intelligent tool holder.

[0018] Furthermore, each smart tool holder corresponds to a unique IP address.

[0019] Furthermore, the smart toolholder's operating data includes force, vibration, and temperature data.

[0020] Furthermore, when the intelligent toolholder is invoked, the tool magazine robot grips the intelligent toolholder and installs it onto the machine tool spindle. The U-shaped slot of the intelligent toolholder's dual slots is filled by the dual jaws on the machine tool spindle. The two proximity switches inside the U-shaped slot of the intelligent toolholder's dual slots are triggered simultaneously, and the intelligent toolholder's power supply module is adaptively turned on, energizing the intelligent toolholder and enabling data acquisition.

[0021] Furthermore, when the intelligent toolholder pauses work and returns to the tool magazine, the tool magazine robot grabs the intelligent toolholder and places it into the machine tool's tool magazine. One of the U-shaped slots in the intelligent toolholder's dual slots is filled by the tool holder's jaws. Only one of the two proximity switches in the intelligent toolholder's dual slots is triggered, and the intelligent toolholder's power-off module adaptively opens, the intelligent toolholder is powered off and data acquisition is turned off, and the duration of the intelligent toolholder's power-on is recorded.

[0022] Furthermore, the intelligent tool holder charging management module includes dual inductive fixed contacts located on the tool holder, and spring pin dual contacts located on the Morse taper end face of the intelligent tool holder;

[0023] The dual inductive fixed contacts and the spring pin dual contacts enable the charging of the smart tool holder.

[0024] Furthermore, the intelligent tool holder power indicator light management and automatic charging control module indicates the remaining power of the intelligent tool holder by adjusting the color of the power indicator light;

[0025] The intelligent tool holder recall management module recalls intelligent tool holders whose remaining battery power is longer than the virtual processing time based on the virtual processing time. If no intelligent tool holder is available, the module will charge the intelligent tool holder.

[0026] Furthermore, when performing a tool changing operation on the smart tool holder, the shared loading and unloading robot grabs the smart tool holder on the machine tool spindle and moves it to the shared tool changing area for tool changing. After the tool changing is completed, the shared loading and unloading robot grabs the corresponding smart tool holder and moves it to the machine tool magazine of the corresponding process for later use, and stores the corresponding IP address information.

[0027] Furthermore, the multi-machine tool collaborative intelligent tool holder management module includes three single-machine tool CNC systems;

[0028] If the single-machine tool CNC system detects two IP addresses, the shared loading and unloading robot will grab the smart tool holder that is far from the tool magazine robot and place it on the machine tool spindle that the single-machine tool CNC system detects has no IP address.

[0029] If the single-machine tool CNC system does not detect two IP addresses, the tool magazine robot will grab the smart tool holder and install it onto the machine tool spindle;

[0030] If the single-machine tool CNC system detects 3 IP addresses, the shared loading and unloading robot will pick up the 2 smart tool holders that are far from the tool magazine robot and place them on the machine tool spindle that the single-machine tool CNC system does not detect.

[0031] If the single-machine tool CNC system does not detect 3 IP addresses, the tool magazine robot will grab the smart tool holder and install it onto the machine tool spindle.

[0032] The technical effects of this invention are undeniable, and its beneficial effects are as follows:

[0033] 1) For the application of intelligent tool holders for end effectors in unmanned smart factories, this invention links the intelligent tool holders together during the processing, can communicate with cloud data, and manage the use of multiple intelligent tool holders in real time through the CNC system.

[0034] 2) In the future, smart factories will be unmanned. Adaptive power supply / power failure management can rely on proximity switches, the linkage of dual chucks on the machine tool spindle and the tool holder chuck to realize intelligent tool holders installed on the machine tool spindle for adaptive power supply and return to the machine tool magazine for adaptive power failure.

[0035] 3) By relying on the dual inductive fixed contacts of the tool magazine and the dual contact of the spring pin on the Morse taper end face of the intelligent tool holder, convenient charging management of the intelligent tool holder returning to the machine tool magazine can be realized.

[0036] 4) Based on the cloud-based CNC program and virtual machining time, the smart tool holder can call up the smart tool holder with the corresponding battery level. If the machining time of the smart tool holder is less than 0.5 hours, the smart tool holder can automatically return to the tool magazine for charging management.

[0037] 5) Under current operating conditions, tool status information is only reflected by the tool usage time monitored by the CNC system to reflect tool life. Based on the force and vibration data collected in real time by the intelligent tool holder, it can be linked with the CNC system to continue to monitor the force and vibration signals in the machining process in real time when the tool usage time exceeds the expected tool life, thereby improving the tool life.

[0038] 6) With the help of shared loading and unloading robots, the position of intelligent tool holders can be controlled in conjunction with multiple machine tools to improve the utilization rate of intelligent tool holders in the workshop.

[0039] 7) By querying the materials, tools and cutting parameters used in the cloud, when the same materials, tools and cutting parameters have been used, the smart tool holder can be replaced with a conventional tool holder, thereby improving the data collection rate of the smart tool holder under multiple working conditions.

[0040] The workshop management system based on intelligent tool holders provided by this invention can meet the needs of energy management, tool life management and multi-tool operation management in the process of intelligent manufacturing. It can improve the utilization rate of intelligent tool holders and the precise management of the workshop, and therefore has broad application prospects in the field of intelligent manufacturing.

[0086] If the single-machine tool CNC system does not detect two IP addresses, the tool magazine robot will grab the smart tool holder and install it onto the machine tool spindle;

[0087] If the single-machine tool CNC system detects 3 IP addresses, the shared loading and unloading robot will pick up the 2 smart tool holders that are far from the tool magazine robot and place them on the machine tool spindle that the single-machine tool CNC system does not detect.

[0088] If the single-machine tool CNC system does not detect 3 IP addresses, the tool magazine robot will grab the smart tool holder and install it onto the machine tool spindle.

[0089] Example 11:

[0090] A workshop management system based on intelligent toolholders includes an intelligent toolholder recall management module, an adaptive power supply management module, an adaptive power failure management module, an intelligent toolholder charging management module, an intelligent toolholder power indicator light management and automatic charging control module, an intelligent toolholder-based tool life management module, a multi-machine tool collaborative intelligent toolholder management module, and an intelligent toolholder experience-based replacement management module.

[0091] The intelligent tool holder call management module performs cloud-based intelligent process division based on the three-dimensional digital model of the workpiece to be processed. The cloud provides the machining program to the CNC system. The CNC system uses the CNC machining center as a carrier and sequentially calls intelligent tool holder A, intelligent tool holder B, and intelligent tool holder C using IP addresses 192.168.4.1, 192.168.4.2, and 192.168.4.3. The working time of intelligent tool holders A / B / C can all meet 12 hours of data acquisition.

[0092] The adaptive power supply management module corresponding to the intelligent tool holders A / B / C is controlled by the proximity switches. When the intelligent tool holder is retrieved, the tool magazine robot grabs the intelligent tool holder and installs it onto the machine tool spindle. The U-shaped slot of the intelligent tool holder's double slot is filled by the double jaws on the machine tool spindle. The two proximity switches in the U-shaped slot of the intelligent tool holder's double slot are triggered simultaneously, and the intelligent tool holder power supply module is adaptively turned on, so the intelligent tool holder is powered on and data acquisition is started.

[0093] The adaptive power-off management module corresponding to the intelligent tool holders A / B / C also relies on proximity switches for control. When the intelligent tool holder returns to the tool magazine, the tool magazine robot grabs the intelligent tool holder and places it into the machine tool magazine. One of the U-shaped slots in the dual slots of the intelligent tool holder is filled by the tool holder claw. Only one of the two proximity switches in the dual slots of the intelligent tool holder is triggered, and the intelligent tool holder power-off module is adaptively opened. The intelligent tool holder is powered off and data acquisition is turned off. The CNC system records the duration of power-on of the intelligent tool holder.

[0094] The intelligent tool holder charging management module is equipped with dual inductive fixed contacts on the tool magazine holder, and the intelligent tool holder has corresponding spring pin dual contacts on the Morse taper end face. The intelligent tool holder can be conveniently charged when it returns to the tool magazine.

[0095] The intelligent toolholder power indicator and automatic charging control module displays green LEDs indicating a power level of 60% or higher, yellow LEDs indicating a power level between 20% and 60%, and red LEDs indicating a power level of 20% or lower. The CNC system receives the cloud-based CNC program and virtual machining time. If the virtual machining time is 7.2 hours or more, the tool magazine robot uses the green LED intelligent toolholder for machining; if the virtual machining time is 2.4 hours or more but less than 7.2 hours, the tool magazine robot uses the yellow LED intelligent toolholder; and if the virtual machining time is 2.4 hours or less, the tool magazine robot uses the red LED intelligent toolholder. If the CNC system records a machining time of 11.5 hours or more, the intelligent toolholder returns to the tool magazine for automatic charging; if the CNC system records a machining time of less than 11.5 hours, the intelligent toolholder continues machining normally.

[0096] In the intelligent toolholder-based tool life management module, the tool magazine robot grips the intelligent toolholder onto the machine tool spindle. The CNC system displays the corresponding IP address of the gripped intelligent toolholder and monitors the tool usage time. Simultaneously, the intelligent toolholder monitors force, vibration, and temperature signals during machining in real time. If the CNC system detects that the tool usage time does not exceed the set tool life, the machine tool operates normally. If the CNC system detects that the tool usage time exceeds the set tool life, the intelligent toolholder determines whether the flank wear exceeds a set threshold based on the force and vibration signals during machining. If it exceeds the set threshold, a shared loading / unloading robot grips the intelligent toolholder on the machine tool spindle and moves it to the shared tool changing area for tool changing. After tool changing, to avoid spindle stoppage affecting machining efficiency, the shared loading / unloading robot grips the corresponding intelligent toolholder and moves it to the corresponding machine tool magazine for later use. The CNC system stores the corresponding IP address information. If the force and vibration signals collected in real time by the intelligent toolholder do not exceed the set threshold, the machine tool operates normally to extend tool life.

[0097] In the multi-machine tool collaborative intelligent tool holder management module, the cloud sends machining programs to CNC systems A, B, and C. If a single-machine CNC system detects two IP addresses, the shared loading / unloading robot picks up the intelligent tool holder furthest from the tool magazine robot and places it onto the machine spindle of a machine where the single-machine CNC system does not detect an IP address. If the single-machine CNC system does not detect two IP addresses, the tool magazine robot picks up the intelligent tool holder and installs it onto the machine spindle. If the single-machine CNC system detects three IP addresses, the shared loading / unloading robot picks up two intelligent tool holders furthest from the tool magazine robot and places them onto the machine spindle of a machine where the single-machine CNC system does not detect an IP address. If the single-machine CNC system does not detect three IP addresses, the tool magazine robot picks up the intelligent tool holder and installs it onto the machine spindle.

[0098] If the cloud query indicates that the corresponding material, tool, and cutting parameters have been used, the CNC system will call the intelligent tool holder to perform milling and save the corresponding material, tool, cutting parameters, force, vibration, and temperature data in the cloud. If the cloud query indicates that the corresponding material, tool, and cutting parameters have not been used, the CNC system will call a conventional tool holder to perform milling to improve the data acquisition rate of the intelligent tool holder's multi-condition monitoring.
