On the basis of the structures of the rotary multi-tool synchronous taking and changing device 1, the tool magazine device 2 and the multi-spindle processing machine tool which are correspondingly disclosed in the figures 1 to 7, the multi-tool synchronous taking and changing process is described in detail.

In one tool changing process, the tool shank unloaded from spindle 9 into magazine 2 is defined as first tool shank 2313-1, and the tool shank loaded from magazine 2 into spindle 9 is defined as second tool shank 2313-2. The tool pocket associated with the first handle 2313-1 is defined as a first tool pocket 2312-1, and the tool pocket associated with the second handle 2313-2 is defined as a second tool pocket 2312-2.

The specific implementation action process comprises the following four steps:

the method comprises the following steps: before each main shaft 9 finishes machining by using the first tool shank 2313-1, the tool feeding driving mechanism 131 rotates to drive the 4 tool taking and changing assemblies 14 on the tool feeding sliding plate 12 to move to preset positions of the tool channels 232 along the Y direction, and the tool clamping opening of each second tool holder 143 is positioned right below the corresponding second tool shank 2313-2. Subsequently, the lifting cylinder rod 2141 retracts to drive the lifting slide plate 213 and the 4 second tool handles 2313-2 to move in the Z-direction; then, the transverse moving driving mechanism 2231 rotates to drive the transverse moving sliding plate 221 and the 4 second tool shanks 2313-2 to move towards the corresponding tool clamping openings of the second tool holders 153 (X direction) until each tool clamping opening 1 is concentric with the corresponding second tool sleeve 2312-2; at this point, each second toolholder 153 grasps a corresponding second tool shank 2313-2. Then, the lifting cylinder rod 2141 extends to drive the lifting slide plate 213 to move in the Z direction, and the 4 second tool shanks 2313-2 are pulled out from the corresponding second tool sleeves 2312-2. The tool changing and removing assembly 14 completes the operation of taking 4 second tool shanks 2313-2.

Step two: subsequently, the 4 spindles 9 stop machining and move to the designated tool changing position along with the X-axis 5 and the Z-axis 7. Then, the isolation door 101 is raised, and the first chamber 24 and the second chamber 43 penetrate. Then, the knife feeding driving mechanism 131 drives the knife feeding sliding plate 12 and drives the 4 knife taking and changing assemblies 14 to move to the lower part of the main shaft 9 along the Y-direction; simultaneously, the rotary driving mechanism 152 rotates to drive the tool-taking and changing assemblies 14 to rotate forward by 90 degrees, so that the tool-clamping opening of each first tool holder 142 faces the spindle 9. Subsequently, the knife feeding sliding plate 12 continues to move along the Y-direction under the driving of the knife feeding driving mechanism 131 until the knife clamping opening 1 of each first knife clamp 142 is concentric with the corresponding first knife handle 2313-1; at this time, each first toolholder 142 grips the corresponding first shank 2313-1. Subsequently, each spindle 9 releases the first handle 2313-1 and moves with the Z-axis 7 in the Z-direction to a safe position.

Step three: after the Z shaft 7 reaches the safety position, the rotary driving mechanism 152 drives each tool taking and changing assembly 14 to rotate forwards by 180 degrees, and the positions of the first tool handle 2313-1 and the second tool handle 2313-2 of each main shaft 9 are changed; at this time, 4 second tool shanks 2313-2 are positioned directly below the corresponding spindle 9. Subsequently, the 4 main shafts 9 move along the Z-direction along the Z axis 7, and after the tool changing position is reached, each main shaft 9 clamps the corresponding second tool handle 2313-2; then, the tool feeding driving mechanism 131 drives the tool feeding sliding plate 12 to move in the Y direction, and drives 4 second tool holders 143 to separate from the corresponding second tool shanks 2313-2. Finally, the 4 spindles 9 are driven by the Z shaft 7 to move in the Z direction, and the 4 second tool shanks 2313-2 are conveyed to a safety position.

Step four: the 4 tool-changing assemblies 14, each holding a first tool sleeve 2312-1, are driven by the rotary drive mechanism 152 to rotate forward by 90 degrees, and move along the Y + direction under the drive of the tool-feeding drive mechanism 131 to enter each tool channel 232. Subsequently, the isolation door 101 is lowered, and the first chamber 24 and the second chamber 43 are blocked. At this time, the pocket mouths of the 4 first tool holders 142 face the corresponding first pocket 2312-1. The transverse moving driving mechanism 2231 rotates to drive 4 first knife sleeves 2312-1 on the transverse moving sliding plate 221 to move to the position right above the corresponding first knife handles 2313-1 along the X-direction, and the lifting cylinder rod 2141 retracts to drive the whole transverse moving mechanism and the knife assembly 23 to move towards the Z-direction; the first handle 2313-1 is clamped by the tool sleeves 2312-1. Then, the traverse driving mechanism 2231 rotates to drive the 4 first knife sleeves 2312-1 on the traverse sliding plate 221 and the corresponding first knife handles 2313-1 to move along X. Thus, the first toolholder 2313-1 is disengaged from the first toolholder 142 and enters the first sleeve 2312-1, thereby completing a tool changing process. The lifting cylinder rod 2141 extends out to drive the cutter assembly to move to the initial position along the Z-direction.
