[0003] However, after practice by relevant technical personnel, it was found that the previous tool library had the following technical problems:
[0004] 1. Unable to achieve multi-directional tool change: Most tool magazines sold on the market can only change tools in the same direction. For example, when the spindle is equipped with a side head or the spindle tool change direction is different from the tool direction, it is impossible to change tools in multiple directions in the same tool magazine. Otherwise, a complex structure is required to achieve steering.
[0005] 2. Problems of small tool magazine capacity and single-specification tools: The tool magazines sold on the market can hold a limited number of tools, and the same tool magazine cannot carry tools of different specifications. For example, when the specifications of the taper hole on the spindle side are different from those of the spindle, the versatility is limited.
[0006] 3. It takes up a lot of space: In addition, the tool magazines sold on the market have a complex structure and cannot effectively reduce the size of the tool magazine, thereby increasing the size of the processing machine.

For ordinary technicians in this field, the specific meanings of the above terms in this utility can be understood by specific circumstances.
[0038] See also Figure 1 , please refer to the embodiments of the present invention Figure 1 The processing machine 1 has at least one spindle 1a, a working platform 1b, a tool storage area S and a tool changing area C. The number of the spindle 1a can be single or multiple. The tool storage area S is adjacent to the tool changing area C. The spindle 1a is arranged in the tool changing area C for tool changing operation. In this embodiment, the spindle 1a can slide along the Y axis and the axis 112a is arranged parallel to the Z axis.
[0039] The pivoting tool magazine mechanism 100 includes a tool storage device 10 and a tool changing device 20 .
[0040] See also Figures 1 to 3 The knife storage device 10 is located in the knife storage area S. The knife storage device 10 has at least one knife placement assembly 11 and a steering module 12. The knife placement assembly 11 is pivotally connected to the steering module 12, and the knife placement assembly 11 stores multiple sets of knives 2 at the same time. Figure 3 As shown, the steering module 12 can drive the tool placement assembly 11 to pivot along the XY plane, so that the tool placement assembly 11 can be switched between a first position P1 in the tool storage area S and a second position P2 in the tool change area C. Since the first position P1 and the second position P2 are roughly L-shaped, a working space can be vacated to facilitate the operation of the processing machine 1.
[0041] The pivoting tool magazine mechanism 100 further includes a rotating device 30, which is located at the side of the tool changing area C. The rotating device 30 can rotate a bracket 112 of the tool placement assembly 11, thereby making the tool 2 conform to the tool changing direction of the spindle 1a, so as to achieve a multi-directional tool changing function.
[0042] See also Figure 4 In one embodiment of the present disclosure, each knife assembly 11 has a reversing gear 111, a bracket 112 and a knife holder seat 113. A first end E1 of the bracket 112 is connected to the reversing gear 111. The knife holder seat 113 is slidably disposed on the bracket 112, that is, the knife holder seat 113 can slide on the bracket 112.
[0043] See also Figure 4, the steering module 12 has a first power unit 121 and a driving gear 122. In this embodiment, the first power unit 121 can be a motor. The driving gear 122 is connected to the first power unit 121, and the first power unit 121 drives the driving gear 122 to rotate clockwise or counterclockwise. In addition, the driving gear 122 is movably engaged with the reversing gear 111, that is, the driving gear 122 is selectively combined with or separated from the reversing gear 111. In combination with the above technical features, the bracket 112 can be pivoted along the XY plane to switch between the first position P1 and the second position P2 to transport or store the tool 2. Please refer to Figure 4 In order to increase the number of stored tools 2, the tool storage device 10 is stacked with multiple tool placement assemblies 11 along the Z-axis direction. Figure 5 , multiple tool placement assemblies 11 can be lifted and moved along the Z-axis direction, and one group of reversing gears 111 is selected to be positioned at the first position P1, while the other reversing gears 111 are positioned at a standby position P3 of the tool storage area S. The standby position P3 can be the upper side or the lower side of the first position P1. When one group of reversing gears 111 is positioned at the first position P1, the reversing gear 111 at the first position P1 is meshed with the driving gear 122, and the first power unit 121 drives the driving gear 122 and the reversing gear 111 to rotate, so that the bracket 112 at the first position P1 can switch between the first position P1 and the second position P2.
[0044] In one embodiment of the present disclosure, the knife storage device 10 has a lifting module 13. The lifting module 13 has a second power unit 131, a lifting seat 132 and a lifting rod 133. In this embodiment, the second power unit 131 can be a combination of a motor, a screw and a linear rail. The lifting seat 132 is connected to the second power unit 131, and the second power unit 131 drives the lifting seat 132 to move up and down along the Z axis to displace multiple knife placement assemblies 11. The lifting rod 133 is arranged on the lifting seat 132 along the Z axis direction, and the lifting rod 133 moves up and down with the movement of the lifting seat 132. The reversing gears 111 of each knife placement assembly 11 are arranged on the lifting rod 133 at intervals along the Z axis direction. Further, the lifting rod 133 is penetrated by multiple reversing gears 111, so that the multiple reversing gears 111 are arranged in series on the lifting rod 133, and each reversing gear 111 is in a horizontal form, and then movably meshed with the driving gear 122.
[0045] The tool changing device 20 is located in the tool changing area C. Figure 6 When the tool setting assembly 11 is located at the second position P2, the tool changing device 20 can drive the tool setting assembly 11 along the X-axis direction to switch between the second position P2 and a tool changing position P4 in the tool changing area C, so that the spindle 1a can remove or put back the tool 2 from the tool setting assembly 11.
[0046] During the tool removal operation, the tool holder 113 carries the tool 2, and the tool changing device 20 drives the tool holder 113 along the X-axis direction from the second position P2 to the tool changing position P4. When the tool holder 113 is located at the tool changing position P4, the spindle 1a descends along the Z-axis direction to the tool changing position P4 to grab the tool 2. Then, the spindle 1a rises and resets after grabbing the tool 2, and the tool holder 113 retreats to the second position P2 to complete the tool removal operation.
[0047] In the tool return operation, the spindle 1a moves along the Y axis to the tool return position where the tool holder seat 113 does not carry the tool 2, and descends along the Z axis to the tool change position P4. The tool change device 20 drives the tool holder seat 113 along the X axis from the second position P2 to the tool change position P4 and causes the tool holder of the tool holder seat 113 to clamp the tool 2. After the spindle 1a releases the tool, it rises along the Z axis to the original position, and the tool holder seat 113 returns to the second position P2 to complete the tool return operation.
[0048] In one embodiment of the present disclosure, each of the plurality of tool placement assemblies 11 has a guide rail 114. The plurality of guide rails 114 are connected to the plurality of tool holders 113, and allow the plurality of tool holders 113 to slide on the plurality of brackets 112. In this embodiment, the number of each set of guide rails 114 is two, and they are connected to both sides of each tool holder 113. Figure 6 and Figure 7 The tool changing device 20 has a push module 21 and an upper and lower module 22. When one of the brackets 112 is located at the second position P2, the upper and lower modules 22 move the push module 21 downward to the tool changing area C. At this time, the push module 21 can push the tool holder 113 located at the second position P2, so that the guide rail 114 slides on the bracket 112, and then the tool holder 113 switches between the second position P2 and the tool changing position P4 along the X-axis direction.
[0049] See also Figure 3 , each of the plurality of tool holder seats 113 has a first engaging portion 113a. The push module 21 has a second engaging portion 211. When the upper and lower modules 22 move the push module 21 downward to the tool changing area C, the first engaging portion 113a engages with the second engaging portion 211, and the tool holder seat 113 located at the second position P2 is pushed by the push module 21. Furthermore, each first engaging portion 113a has a groove at the top, and each second engaging portion 211 has a protrusion at the bottom, and the shape of the groove matches the shape of each protrusion so as to engage with each other.
[0050] See also Figure 8In order to fix the tool placement assembly 11 at the second position P2, the rotating device 30 of the pivoting tool magazine mechanism 100 further includes a limiting module 31. The limiting module 31 is located at the side of the tool changing area C. The limiting module 31 and the tool placement assembly 11 at the second position P2 have the same height. When the bracket 112 is at the second position P2, the bracket 112 is connected to the limiting module 31 to ensure the position of the tool placement assembly 11.
[0051] See also Fig. 9 , the tool 2 of this embodiment is in a horizontal position. Figure 8 and Fig.10 In order to cope with the tool 2 in a horizontal position, the bracket 112 has a second end E2 and an axis 112a. The second end E2 is located at the other end of the bracket 112 relative to the first end E1. The axis 112a is adjacent to the first end E1; in this embodiment, the axis 112a is disposed at the corner of the bracket 112. In addition, the bracket 112 can be rotated around the axis 112a.
[0052] See also Figure 8 In order to achieve the function of multi-directional tool change, the pivoting tool magazine mechanism 100 further includes a rotating device 30. The rotating device 30 can be equipped with a rotating motor. When the second end E2 of the bracket 112 is connected to the limit module 31, the rotating device 30 drives the second end E2 to rotate around the axis 112a of the bracket 112, thereby allowing the tool 2 to rotate together to match the tool change direction of the spindle 1a.
[0053] In summary, the present disclosure has the following technical features:
[0054] 1. High efficiency: The tool storage device 10 of the present invention only needs to be pivoted along the XY plane to switch the tool placement assembly 11 between the tool storage area S and the tool changing area C, so that the spindle 1a can replace the tool 2, further increasing the efficiency of replacing the tool 2.
[0055] 2. Large capacity feature: The tool storage device 10 disclosed in the present invention can store multiple sets of tools 2 in the longitudinal or transverse direction at the same time, and according to the needs, tool holders and tools 2 or spindle heads or side heads of the same or different specifications can be installed on the tool holder seat 113 to meet the working requirements of the processing machine 1.
[0056] 3. Space-saving feature: Since the tool storage device 10 and the tool changing device 20 of the present disclosure perform tool changing operations directly above the working platform 1 b , this approach can reduce the volume occupied by the processing machine 1 .
[0057] 4. Having different working modes: The present disclosure provides a vertical posture or a horizontal posture or a vertical and horizontal posture mixed to store the tool 2 to meet different implementation situations. In the vertical posture, it is more convenient for the spindle 1a to take and put the tool 2, and the structure is simpler. In the horizontal posture, the upper and lower spacing distances of each tool placement component 11 can be configured closer, and the number of tool placement components 11 can be increased, thereby increasing the number of stored tools 2. And when the spindle 1a grabs the side head or the tool change direction of the spindle 1a is different from that of the tool 2, the bracket 112 can be rotated to achieve a multi-directional mixed tool change function.

Although the present invention has been disclosed as a preferred embodiment as above, it is not used to limit the present invention. Any technician familiar with this profession can make some changes or modify the technical contents disclosed above into equivalent embodiments without departing from the scope of the technical solution of the present invention. However, any simple modification, equivalent change and modification made to the above embodiments according to the technical essence of the present invention without departing from the content of the technical solution of the present invention still fall within the scope of the technical solution of the present invention.
