The tool changing method comprises the steps of changing a tool bit on a main shaft in the machining process, replacing the tool bit on the main shaft aiming at materials needing to be machined by a plurality of different tool bits to realize machining mode switching, moving a mechanical arm to a tool taking point of a tool magazine when the tool bit on the main shaft is machined before a tool changing instruction is carried out, moving a transverse sliding table of the tool magazine to be matched with the mechanical arm to enable one tool holder of a tool holder group to grab a target tool bit from an upper matrix tool magazine, pausing machining of a machining main shaft when the tool changing instruction is carried out, completing machining of the materials by the tool bit used by the main shaft, moving the machining main shaft to the tool changing point, moving the mechanical arm to the tool changing point, taking an old tool bit from the main shaft by another idle tool holder of the tool holder group on the mechanical arm under the matching of the machining main shaft, moving the machining main shaft in a parabolic mode (commonly called frog leaping-jumping, and the manipulator leaves the tool changing point, the changed old tool bit is loaded into the matrix tool magazine under the coordination of the transverse movement of the tool magazine, and the manipulator moves to the next target tool bit position for preparing the tool or moves to the position above the material groove to pick up the target material for preparing the material.
And (5) finishing tool changing, tool changing required by subsequent processing and the like.
The processing materials are changed, when the materials loaded for the first time or the last time are processed, one group of pickers of the manipulator obtains the second piece or the Nth piece of materials to be processed in the material groove by using proper time points, the other group of pickers are idle, and in the subsequent process, the tool changing is not influenced by material changing because the tool holder group on the manipulator is arranged on the back of the bearing body. The control system sends a material changing instruction, the last material is processed, one group of pickers in the picking and placing parts on the mechanical arm picks up the material to be processed, the other group of pickers is idle, the mechanical arm drives the picking and placing parts to enter the processing area, the workbench moves to the position below the picking and placing parts of the mechanical arm, the idle pickers pick up the processed material on the workbench, the mechanical arm is slightly lifted, the workbench moves to a designated position to receive the second or Nth material to be processed, the clamp positions the loaded material, the mechanical arm leaves the processing area to complete material changing, the processing main shaft starts processing, meanwhile, the manipulator drives the taking and placing part to load the finished materials into a finished material area in the groove, the other group of pickers of the manipulator continuously takes the next material to be processed from the groove, the manipulator moves to a waiting area or a tool storage for preparing tools, and the material taking and changing are carried out in a circulating mode until the materials in the groove are completely processed.
It can be understood that, in the initial process, the multiple groups of pickers on the manipulator, any one of the pickers in tandem can obtain one material to be processed, and the two groups of pickers in tandem can also respectively obtain two materials to be processed, wherein one material to be processed can be loaded into the workbench as a first material to be processed, and the other material to be processed can be replaced as a second material to be processed after the first material to be processed is completed, namely, two materials to be processed are obtained at one time respectively.
In the initial process, no matter a material or two materials are obtained on the manipulator taking and placing part, the tool holder group can also be used for taking a tool bit or a group of tool bits in the tool magazine for standby, the tool bit can be taken firstly and then the material is taken, or the material is taken firstly and then the tool bit is taken, and related programs can be adjusted according to technological requirements.
According to the scheme, when the tool is changed, one tool holder in the tool holder group on the back of the bearing body inserts the old tool bit into the tool magazine, the other tool holder takes out the new tool bit in the tool magazine, the bearing body moves to a tool changing point below the machining main shaft, the idle tool holder takes out the old tool bit on the machining main shaft, and the tool holder clamping the new tool bit is arranged on the machining main shaft;
when the materials are changed, the material-taking part on the front side of the bearing body picks up the processed materials in the processing area and puts the processed materials back to the material area, and the material-taking part on the front side of the bearing body picks up the materials to be processed in the material area and puts the materials into the processing area.
When the processing main shaft processes materials in the processing area, one of the pickers of the taking and placing part is idle, and the other picker picks up a material to be processed from the material area and waits in the processing area.
In the embodiment, the two sides of the bearing body of the manipulator are provided with the taking and placing devices with different functions, wherein the downward-arranged picking device is used for taking and placing materials; the tool holder group that sets up is used for getting of tool bit to put, corresponds with it, and in workstation the place ahead, get and put a below and set up shared silo, and main shaft the place ahead, tool holder group top or workstation, silo top set up the tool magazine, and the supporting body of manipulator wears handsome reloading and tool changing between them. Due to the compact structural layout, the occupied space is reduced, and the space utilization rate of the field is improved; different fetching devices are arranged on the rotating parallel surface of the manipulator bearing body, so that the motion function of the manipulator is shared, and the time utilization rate of the manipulator is improved; the tool magazine and the material groove are arranged one above the other, so that the movement path of material changing and tool changing is shortened, and the efficiency of material changing and tool changing is improved.
