[0002] In high-precision manufacturing processes such as gear machining, tool changes are frequent and require sophisticated storage and management. Traditional tool storage and retrieval systems typically rely on manual tool changes and storage, which not only increases operational complexity but also increases the risk of tool loss or damage, severely impacting processing efficiency and production quality. Furthermore, dust, oil, and other contaminants in the machining environment can easily penetrate the tool storage area, causing rust or wear on the tool surfaces, further increasing the frequency of tool replacement and maintenance.

[0003] Existing tool storage devices mostly employ simple manual storage or automated retrieval with the assistance of robotic arms. However, these devices are typically complex in structure, occupy a large space, are difficult to maintain, and cannot guarantee the airtight storage of tools, thus failing to effectively prevent contamination and damage to the tools caused by the external environment. Therefore, there is an urgent need for a tool holder device that is simple in structure, efficient, automated, and can effectively seal and preserve tools.

[0004] To address the aforementioned problems, this utility model provides a tool holder for gear machining. This tool holder, through a precise fit between the rotary disc and the bushing, combined with the eccentric arrangement of the guide wheels, not only ensures smooth and efficient tool storage and retrieval but also significantly reduces manual intervention and improves work efficiency through an automated storage and retrieval mechanism. The design of the receiving slot and magnetic base effectively secures the tool, preventing it from loosening or shifting during storage. Furthermore, the sealed structure of the tool magazine and rotary disc effectively prevents the entry of external contaminants, ensuring the tool remains in good working condition and extending its service life.

Through the rotary disc and several sets of holes on its surface slidingly engaging with the tool holder assembly, combined with the design of the live pin connecting rod and the receiving groove, the tools can be safely stored in the tool magazine compartment and can be easily retrieved when needed.

[0007] The technical solution of this utility model has the following beneficial effects:

[0008] Simple and efficient structure: The precise design of the rotary disk and the sleeve hole, combined with the eccentric arrangement of the guide wheel, makes the storage and retrieval of tools smoother and the operation process simple and efficient.

[0009] Automated storage and retrieval function: Through the linkage between the drive motor and the rotary disk, the tool holder assembly can rotate automatically and realize the radial retraction and storage and retrieval of the tool, which greatly reduces manual intervention, reduces operation error, and improves work efficiency.

[0010] High reliability of tool fixation: The receiving groove and magnetic seat design in the tool holder effectively fix the tool, preventing it from loosening or shifting during storage, thus ensuring the safety of the tool during storage.

[0011] Sealed storage function: The tool magazine compartment and rotary disc structure design ensure that the tools are effectively sealed during storage, preventing external contaminants from entering the tool magazine compartment, ensuring that the tools maintain good working condition, avoiding rust or wear, and extending the tool life.

[0012] This invention, through its rational structural arrangement and precise mechanical coordination, ensures a smoother and more efficient tool storage and retrieval process, thereby improving overall processing efficiency.

[0022] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to specific embodiments and accompanying drawings. It should be noted that, unless otherwise specified, the embodiments and features of the present utility model can be combined with each other.

[0023] It should be understood that these descriptions are merely exemplary and not intended to limit the scope of this invention.

[0024] The following is in conjunction with the appendix Figures 1-5 This invention describes a tool holder for gear machining, provided by some embodiments of the present invention.

[0025] In this embodiment, the tool holder for gear machining includes a tool magazine 100, a drive motor 110, a fixing frame 120, a cover 130, a fixed guide wheel 140, a rotary disk 200, a sleeve hole 210, and a tool holder assembly 300, among other main components.

[0026] The tool magazine compartment 100 is the main support structure in this embodiment, used to house the cutting tools and their related components. The top surface of the tool magazine compartment 100 is provided with an opening slot 150; a drive motor 110 and a fixing bracket 120 are fixedly installed on one side of the tool magazine compartment 100, making the overall structure more stable and convenient for long-term use.

[0027] The drive motor 110 provides rotational power through its connection with the rotary disk 200, enabling the rotary disk 200 to perform indexing rotations, thereby guiding the tool holder assembly 300 to complete related operations. The output end of the drive motor 110 is fixedly connected to the end of the rotary disk 200, allowing the rotary disk 200 to perform precise indexing rotations within the fixed frame 120.

[0028] The cover 130 is located on one side of the tool magazine compartment 100 to protect the internal structure and provide a fixing device to ensure that the guide wheel 140 inside the tool magazine compartment 100 can work stably.

[0029] The fixed guide wheel 140 is installed inside the cover 130 and is eccentrically positioned. The axis of the fixed guide wheel 140 is offset from the center of the rotary disk 200, allowing the tool holder assembly 300 to slide radially during rotation. When the rotary disk 200 rotates, the fixed guide wheel 140 guides the tool holder assembly 300 to retract radially inside the sleeve hole 210 through its eccentric arrangement.

[0030] The rotary disk 200 engages with the tool holder assembly 300 through a series of holes 210 on its surface. The rotary disk 200 is driven by the drive motor 110 to rotate in increments, which in turn drives the tool holder assembly 300 to slide radially, thereby achieving sealed storage and retrieval of the tool.

[0031] The tool holder assembly 300 consists of a tool holder 310 and a movable pin connecting rod 320 fixed to the bottom surface of the tool holder 310. The tool holder assembly 300 is slidably sleeved inside the sleeve hole 210 on the surface of the rotary disk 200 and can rotate with the rotary disk 200. When the tool holder assembly 300 is rotating, one end of the movable pin connecting rod 320 is slidably sleeved inside the fixed guide wheel 140, guiding the tool to move radially inside the sleeve hole 210, thus completing the storage and retrieval of the tool.

[0032] Working principle:

[0033] The working principle of this utility model is as follows: When the tool is stored and used, it is rotated by the rotary disk 200 and the drive motor 110. The rotary disk 200 cooperates with the tool holder assembly 300 through the sleeve hole 210 opened on its surface, so that the tool holder assembly 300 can retract radially within the sleeve hole, thereby driving the tool to complete the storage or retrieval operation.

[0034] When storing tools, the tools are magnetically secured by the receiving slot 311 and the magnetic base 312, ensuring safe storage within the tool magazine compartment 100. When a tool is needed, the drive motor 110 starts, and the rotary disk 200 rotates the tool holder assembly 300. Simultaneously, the guide wheel 140 guides the tool holder assembly 300 to slide radially, pushing the tool out of the tool magazine compartment 100 for quick replacement and retrieval.
