They come in a wide variety of types and designs depending on the machining process and workpiece material. In the daily operation of a CNC machining center, the proper placement and management of cutting tools are crucial for machining accuracy, efficiency, and the overall operational stability of the equipment.

[0003] A CNC tool placement device for a CNC machining center, Chinese Patent No. CN219504302U, includes an outer frame with four sets of support columns fixedly connected to the bottom of the outer wall of the frame. This utility model provides a CNC tool placement device for a CNC machining center. Through a drive motor, the positioning mechanism can rotate stably, allowing the placement plate to rotate to one side of the retrieval window, facilitating tool removal and subsequent CNC machining. Furthermore, the placement plate can simultaneously hold eight sets of tools, and it remains vertical at all times, enhancing the placement and retrieval efficiency.

[0004] Most existing CNC machining centers lack standardized retrieval and recording mechanisms for tool placement devices, allowing staff to take tools at will. This not only makes it difficult to trace tool usage but may also lead to tool loss or misplacement, seriously affecting the smoothness of the production process and the standardization of management.

[0005] To address this, a tool placement device for CNC machining centers is proposed. Utility Model Content

A limiting vertical rod is fixedly connected to the rear end of the U-shaped bracket. An electric rotating shaft is installed at the upper end of the limiting vertical rod. An extension locking strip is connected to the output end of the electric rotating shaft. An information recording board is fixedly connected to the upper end of the extension locking strip. The extension locking strip is located directly above the tool body. A support rotating frame is fixedly connected to the front side of the upper end of the platform. A controller panel is rotatably connected to the upper end of the support rotating frame. Multiple rectangularly distributed support legs are fixedly connected to the lower end of the platform.

[0008] More preferably, a stable shock-absorbing seat is fixedly connected to the lower end of the support leg, and a first horizontal bar is fixedly connected to the rear side of the left and right inner walls of the U-shaped bracket.

[0009] More preferably, a drive gear linkage assembly is installed at the upper end of the first horizontal bar, and a motor is externally connected to the drive gear linkage assembly.

[0010] More preferably, a second horizontal bar is fixedly connected to the front side of the left and right inner walls of the U-shaped bracket, and a transmission gear linkage assembly is installed at the upper end of the second horizontal bar.

[0011] More preferably, a vertically circling rod is fixedly connected to the upper end of the transmission gear linkage assembly, and a vision sensor is fixedly connected to the upper end of the vertically circling rod.

[0014] The present invention has the following advantages due to the adoption of the above technical solution:

[0015] I. This utility model provides a tool placement ring on a U-shaped bracket, which provides a close fit support according to the shape of the tool, reducing the risk of shaking and displacement when placing the tool.

[0026] In the following description, only certain exemplary embodiments are briefly described.

Therefore, the drawings and description are considered to be exemplary in nature and not restrictive.

[0027] The embodiments of this utility model will now be described in detail with reference to the accompanying drawings.

[0028] Example 1

[0029] like Figure 1-3 As shown, this utility model embodiment provides a tool placement device for a CNC machining center, including a device platform 1. Two U-shaped brackets 2 are fixedly connected to the upper end of the device platform 1. Multiple horizontally arranged tool placement rings 3 are provided at the upper end of the U-shaped brackets 2. A tool body is placed inside the tool placement ring 3. A cutting edge vertical head extending into the tool placement ring 3 is provided below the tool body. A limiting vertical rod 4 is fixedly connected to the rear end of the U-shaped brackets 2. An electric rotating shaft 5 is installed at the upper end of the limiting vertical rod 4. An extension locking strip 6 is connected to the output end of the electric rotating shaft 5. An information recording plate 7 is fixedly connected to the upper end of the extension locking strip 6. The extension locking strip 6 is located directly above the tool body. A support rotating frame 19 is fixedly connected to the front side of the upper end of the device platform 1. A controller panel 8 is rotatably connected to the upper end of the support rotating frame 19.

[0030] Multiple rectangularly distributed support legs 10 are fixedly connected to the lower end of the equipment platform 1. A stable shock-absorbing seat 11 is fixedly connected to the lower end of the support leg 10. The stable shock-absorbing seat 11 is located at the lower end of the support leg 10. It is mainly used to enhance the stability of the entire device and effectively reduce the impact of external vibration on the cutting tool.

[0031] Example 2

[0032] like Figure 1 , Figure 4-6 As shown, in one embodiment, a first horizontal bar 12 is fixedly connected to the rear side of the left and right inner walls of the U-shaped bracket 2. An active gear linkage assembly 14 is installed at the upper end of the first horizontal bar 12. A motor 13 is externally connected to the active gear linkage assembly 14. A second horizontal bar 15 is fixedly connected to the front side of the left and right inner walls of the U-shaped bracket 2. A transmission gear linkage assembly 16 is installed at the upper end of the second horizontal bar 15. A vertical surrounding rod 17 is fixedly connected to the upper end of the transmission gear linkage assembly 16. A vision sensor 18 is fixedly connected to the upper end of the vertical surrounding rod 17. The two transmission gear linkage assemblies 16 corresponding to each other in the front and rear horizontal directions are meshed and connected. The vision sensor 18 is located outside the blade vertical head. The controller panel 8 is electrically connected to multiple limiting rods 4, motor 13, and vision sensor 18 through wires.

[0033] The motor 13 drives the active gear linkage assembly 14 to operate, which in turn drives the transmission gear linkage assemblies 16 on the front sides of the left and right inner walls of the U-shaped bracket 2 to rotate synchronously. Since the two corresponding transmission gear linkage assemblies 16 mesh with each other, multiple vertical surrounding rods 17 rotate around the outside of the blade head. The vision sensor 18 at the top of the vertical surrounding rods 17 moves accordingly to perform all-round detection of the blade. This design can detect whether the blade is damaged in time, which greatly improves the functionality of the device. Compared with the existing technology, the detection of the cutting edge often relies on manual visual observation or the use of complex and expensive detection equipment. This solution provides efficient and reliable auxiliary functions for tool management in CNC machining centers through automated detection methods.

[0034] In operation, this invention features the following: During the tool placement stage, the tool body is positioned within multiple horizontal tool placement rings 3 on the upper end of the U-shaped bracket 2. The vertical blade head extends into the tool placement rings 3, providing a close and stable support. A stable shock-absorbing seat 11 is located at the lower end of the support leg 10, primarily enhancing the overall stability of the device and effectively reducing the impact of external vibrations on the tool. When the tool is in storage, the electric rotating shaft 5 drives the connected extension locking bar 6 to rotate horizontally to directly above the tool body, locking the tool. The extension locking bar 6 does not directly contact the tool body, avoiding wear caused by long-term friction and extending the device's lifespan. Afterward, the operator needs to input their work number on the controller panel 8. The support rotating frame 19, connected to the equipment platform 1 and rotatably connected to the controller panel 8, provides a flexible operating angle for the controller panel 8. When the operator inputs their work number on the controller panel 8 and activates the electric rotating shaft 5 to retrieve the tool, they can adjust the controller panel 8 by rotating the support rotating frame 19 according to their operating habits and the actual working scenario. The angle makes operation more convenient, and the corresponding electric rotating shaft 5 can be turned on to rotate, so that the behavior of the staff in picking up the tool can be recorded. This function effectively prevents the phenomenon of picking up the tool at will, facilitates the precise management of tool use, and improves the standardization and orderliness of tool management in CNC machining centers. In terms of tool detection, the motor 13 drives the active gear linkage assembly 14 to operate. The active gear linkage assembly 14 drives the transmission gear linkage assembly 16 on the front side of the left and right inner walls of the U-shaped bracket 2 to rotate synchronously. Since the two corresponding transmission gear linkage assemblies 16 in the front and rear horizontal directions mesh with each other, multiple vertical surrounding rods 17 rotate around the outside of the vertical head of the blade. The vision sensor 18 at the top of the vertical surrounding rod 17 moves accordingly to perform all-round detection of the blade. This design can detect whether the blade is damaged in time, which greatly improves the functionality of the device. Compared with the existing technology, the detection of the tool blade often relies on manual visual observation or the use of complex and expensive detection equipment. This solution provides efficient and reliable auxiliary functions for tool management in CNC machining centers through automated detection methods.

Any person skilled in the art can easily conceive of various variations or substitutions within the technical scope disclosed in this utility model, and these should all be included within the protection scope of this utility model.
