Description
Technical Field
[0001] This application relates to the field of tool holders in machine tool processing, and more particularly to a tool holder for AGV (Automated Guided Vehicle) trolley transfer. Background Technology
[0002] In machine tool processing, to adapt to different machining tasks, ensure machining accuracy and surface quality, improve machining efficiency, extend tool and machine tool life, and meet the needs of machining complex workpieces and special materials, tool replacement is usually required. Through reasonable management and tool replacement, production efficiency and product quality can be significantly improved, while reducing production costs. In existing technologies, the following methods are commonly used to achieve efficient tool management and replacement: one is manual tool replacement, where the operator retrieves the tool from the tool magazine and installs it onto the machine tool spindle according to machining requirements; another is using a robotic arm in conjunction with a tool magazine to automatically change tools, where the robotic arm retrieves the tool from the magazine and places it in a designated position; yet another method is to use a dedicated transfer device to transport the tool along with its carrier to the vicinity of the machine tool, where a tool-retrieving device completes the installation and replacement. While these methods can meet machining requirements to a certain extent, their specific implementation methods have certain limitations.
[0003] However, inaccurate positioning is a common problem in the tool transfer and installation process in existing technologies, resulting in low tool change efficiency and easy impact on machining accuracy due to positioning deviations. Utility Model Content
[0004] To further improve the positioning accuracy during tool transfer, this application provides a tool carrier for AGV trolley transfer.
[0005] The AGV trolley transfer tool holder provided in this application adopts the following technical solution:
[0006] An AGV (Automated Guided Vehicle) trolley transfer tool holder includes a tool magazine and a support frame. The tool magazine is equipped with a tool retrieval device, and the support frame is installed inside the tool magazine. The trolley also includes a transfer vehicle and a tool holder. The tool holder is mounted on the support frame, and the support frame has a tool mounting seat for tool installation. The transfer vehicle is mounted on the support frame and has a positioning plate with a zero-point positioning mechanism. A positioning plate is also installed at the lower end of the tool holder. The zero-point positioning mechanism is used to fix the positioning plate and transfer the tool holder.
[0007] By adopting the above technical solutions, the combined design of the tool magazine and the support bracket provides a stable storage environment for the tools, facilitating management and maintenance. The combined use of the transfer cart and the zero-point positioning mechanism ensures the precise positioning and fixation of the tool bracket during the transfer process, improving transfer efficiency and reliability. The tool mounting base is designed to accommodate the installation needs of various tool specifications, enhancing the system's flexibility and applicability, and meeting the requirements for machining complex workpieces and special materials.
[0008] In one specific implementation, the tool retrieval device includes a movable slide, a transfer column, and a tool retrieval base. The movable slide is slidably connected to the tool magazine via a first driving member, and the transfer column is slidably connected to the movable slide via a second driving member. A tool clamping structure is installed on the tool retrieval base. The tool clamping structure is used to clamp the tools stored in the tool magazine and place them in the tool mounting base.
[0009] By adopting the above technical solution, the coordinated use of the movable slide, transfer column, and tool holder enables automated tool transfer between the tool magazine and the tool mounting base, improving tool changing efficiency. Specifically, the movable slide is slidably connected to the tool magazine via a first drive component, achieving precise horizontal positioning; the transfer column is slidably connected to the movable slide via a second drive component, further providing vertical position adjustment capability, ensuring the tool clamping structure accurately reaches the target position. The tool clamping structure can securely hold the tools stored in the tool magazine and place them in the tool mounting base, ensuring the stability and reliability of the tool changing process, thereby improving the overall machining system's operating efficiency and machining accuracy.
[0010] In one specific implementation, the tool clamping structure includes a rotary seat, a rotary drive, and a tool clamping component. The rotary seat is rotatably connected to the tool take-up seat via the rotary drive. Several tool clamping components are mounted on the rotary seat, and these tool clamping components are installed on the circumferential portion of the rotary seat. The tool clamping components are configured with different specifications for the corresponding tools.
[0011] By adopting the above technical solution, the tool clamping structure can achieve rapid switching and precise clamping of tools of various specifications. The rotary seat is rotatably connected to the tool take-up holder via a rotary drive, allowing the tool clamping seat to rotate flexibly around the rotary seat, thereby quickly positioning the target tool. Several tool clamping seats are installed on the circumferential part of the rotary seat, and are set with different specifications for corresponding tools. This design allows a single clamping structure to adapt to the needs of multiple tools, improves tool change efficiency, reduces equipment downtime, and ensures stability and accuracy during the machining process.
[0012] In one specific implementation, the rotary drive includes a rotary motor, a rotary gear, and a gear ring. The rotary motor is mounted on a tool holder, the rotary gear is mounted on the output shaft of the rotary motor, and the gear ring is mounted on the rotary seat. The rotary gear meshes with the gear ring.
[0013] By adopting the above technical solution, a rotary motor drives a rotary gear to rotate, and the rotary gear meshes with a gear ring to drive the rotary seat to rotate. This structure achieves precise rotational positioning of the tool holder, enables quick switching between tool holders of different specifications, and improves the flexibility and efficiency of the tool removal device. Specific effects include: stable and reliable rotational action is ensured through gear meshing transmission; precise control of the rotary seat makes tool changing more efficient; and the modular design facilitates maintenance and replacement of parts.
[0014] In one specific implementation, the tool holder includes a tool support plate and a limiting plate. The tool support plate is mounted on the limiting plate, and a tool mounting seat is mounted on the tool support plate. Several tool mounting seats are provided, and the specifications of the several tool mounting seats are different. The limiting plate is mounted on the positioning plate through a centering component.
[0015] By adopting the above technical solution, the tool holder consists of a tool support plate and a limiting plate. The tool support plate is equipped with multiple tool mounting seats of different specifications, which can meet the installation requirements of various tools and improve the flexibility of tool management. The limiting plate is mounted on the positioning plate via a centering assembly. Utilizing the limiting guide rail, limiting block, limiting rod, and limiting spring structure of the centering assembly, precise positioning and stable fixation of the tool holder can be achieved during transport, effectively avoiding tool damage or machining errors caused by positional deviation, thereby improving machining accuracy and efficiency.
[0016] In one specific implementation, the centering component includes a limiting guide rail, a limiting block, a limiting rod, and a limiting spring. The limiting guide rail is mounted on a positioning plate, the limiting block is mounted on the limiting guide rail, and a limiting groove is formed on the limiting plate corresponding to the limiting block. The limiting block passes through the limiting groove. The limiting rod is mounted on the limiting plate, passes through the limiting block, and is slidable relative to the limiting block. The limiting spring is sleeved on the limiting rod, with one end of the limiting spring fixedly connected to the limiting rod and the other end fixedly connected to the limiting block.
[0017] By employing the above technical solution, the cooperation of the limiting guide rail, limiting block, limiting rod, and limiting spring enables precise centering of the tool holder on the positioning plate. The limiting guide rail provides guidance for the limiting block, ensuring its movement along a predetermined path, thereby driving the limiting plate to align precisely. The limiting rod passes through the limiting block and allows relative sliding, further enhancing the stability of the centering process. The limiting spring provides buffering and reset functions during centering, effectively reducing impact forces and improving centering accuracy and reliability. Ultimately, this structure significantly improves the positioning accuracy of the tool holder during transport and installation, thus ensuring efficient tool changing and smooth machining operations.
[0018] In one specific implementation, two sets of the limiting block, limiting rod, and limiting spring are provided. The limiting block is installed at both ends of the limiting guide rail, the limiting rod is installed on both sides of the limiting plate, and the limiting spring is provided accordingly.
[0019] By adopting the above technical solution, and by setting the limiting blocks at both ends of the limiting guide rail, along with the two sets of structures of the limiting rod and the limiting spring, a bidirectional guiding and buffering effect can be provided during the installation of the tool holder. This ensures that the limiting plate is accurately aligned on the positioning plate, avoiding offset or jamming caused by unilateral force. The limiting spring effectively absorbs the impact force during installation and provides an automatic reset function, improving installation efficiency and reliability. The overall structural design is compact and stable, significantly improving the stability of the tool holder during transportation and processing, and further ensuring the accuracy and efficiency of tool replacement.
[0020] In one specific implementation scheme, guide blocks are installed on both sides of the support frame, the sidewalls of the two guide blocks on the adjacent side are inclined, and the inclined sidewalls of the guide blocks are thickened from the side away from the support frame to the side adjacent to the support frame. Centering rollers are installed on both sides of the limiting plate.
[0021] By adopting the above technical solution, guide blocks are installed on both sides of the support frame, and the adjacent sidewalls of the guide blocks are inclined, which can guide the limiting plate smoothly into the designated position of the support frame, effectively reducing possible positional deviations during assembly. The design of the guide blocks gradually thickening from the side away from the support frame to the side adjacent to the support frame further enhances the guiding effect and ensures precise centering of the limiting plate. At the same time, the centering rollers installed on both sides of the limiting plate cooperate with the guide blocks, which not only improves the smoothness of the limiting plate's movement but also enhances the stability and reliability of the overall structure, thereby improving the assembly efficiency and accuracy of the tool holder.
[0022] In summary, this application includes at least one of the following beneficial technical effects:
[0023] 1. By cooperating with the zero-point positioning mechanism and the positioning plate, the tool holder is accurately positioned, effectively solving the problem of inaccurate positioning in the existing technology, thereby improving tool changing efficiency and ensuring machining accuracy;
[0024] 2. By utilizing the collaborative work of transfer vehicles and tool carriers, the tool transfer process is simplified, complex operation steps are reduced, equipment maintenance difficulty and cost are lowered, and the needs of modern manufacturing industry for efficient tool management are met;
[0025] 3. The design of the support bracket, guide block and centering roller ensures the stability of the tool holder during installation and transportation, further improving the overall reliability and service life of the system. Attached Figure Description

The tool carrier 4 is equipped with a tool mounting seat for tool installation. The transfer vehicle 3 is installed at the support frame 2 and has a positioning plate. A zero-point positioning mechanism is installed on the positioning plate. The positioning plate is also installed at the lower end of the tool carrier 4. The zero-point positioning mechanism is used to fix the positioning plate and transfer the tool carrier 4, thus improving tool transfer efficiency and positioning accuracy.
[0032] The tool retrieval device 5 includes a movable slide 51, a transfer column 52, and a tool retrieval base. The movable slide 51 is slidably connected to the tool magazine 1 via a drive component to achieve linear motion; the transfer column 52 is slidably connected to the movable slide 51 via a drive component to achieve vertical motion; a tool clamping structure is installed on the tool retrieval base, which can be a robotic gripper or a magnetic clamping device, for clamping the tools stored in the tool magazine 1 and placing them in the tool mounting base.
[0033] The tool clamping structure further includes a rotating base 54, a rotary drive 55, and a tool clamping component 56. The rotating base 54 is rotatably connected to the tool take-up holder via the rotary drive 55, for example, using a stepper motor to drive a worm gear for smooth rotation. Several tool clamping seats are mounted on the rotating base 54; these clamping seats can be designed in different specifications according to actual needs, suitable for tools of different diameters or shapes. The rotary drive 55 specifically includes a rotary motor, a rotary gear, and a gear ring. The rotary motor is mounted on the tool take-up holder, the rotary gear is mounted on the output shaft of the rotary motor, and the gear ring is mounted on the rotating base 54. The rotary gear meshes with the gear ring to ensure the accuracy of the rotational action.
[0034] like Figure 2 As shown, the tool holder 4 consists of a tool support plate 41 and a limiting plate 42. The tool support plate 41 is mounted on the limiting plate 42, and a tool mounting seat is installed on the tool support plate 41. Several tool mounting seats are provided, and the specifications of the tool mounting seats are different to accommodate various types of tools. The limiting plate 42 is mounted on the positioning plate via a centering assembly 6, which specifically includes a limiting guide rail 61, a limiting block 62, a limiting rod 63, and a limiting spring 64. The limiting guide rail 61 is mounted on the positioning plate, and the limiting block 62 is mounted on the limiting guide rail 61. A limiting groove is opened on the limiting plate 42 corresponding to the limiting block 62, and the limiting block 62 is set through the limiting groove. The limiting rod 63 is mounted on the limiting plate 42, passes through the limiting block 62, and can slide relative to the limiting block 62. The limiting spring 64 is sleeved on the limiting rod 63, with one end of the limiting spring 64 fixedly connected to the limiting rod 63 and the other end fixedly connected to the limiting block 62. This design ensures the stability of the tool holder 4 during transport while improving positioning accuracy.
[0035] Furthermore, two sets of limiting blocks 62, limiting rods 63, and limiting springs 64 are provided. The limiting blocks 62 are installed at both ends of the limiting guide rail 61, the limiting rods 63 are installed on both sides of the limiting plate 42, and the limiting springs 64 are installed accordingly. This symmetrical design enhances the balance of the structure and avoids the offset problem caused by unilateral force.
[0036] Guide blocks 7 are installed on both sides of the support frame 2. The sidewalls of the adjacent guide blocks 7 are inclined, and the inclined sidewalls of the guide blocks 7 gradually thicken from the side away from the support frame 2 to the side adjacent to the support frame 2. This design helps guide the tool holder 4 smoothly into the area of the support frame 2 and reduces centering errors. Centering rollers 421 are installed on both sides of the limiting plate 42. The centering rollers 421 work in conjunction with the guide blocks 7 to ensure the precise centering of the tool holder 4 on the support frame 2.
[0037] The implementation principle of the tool carrier 4 for AGV trolley transfer in this embodiment is as follows: by introducing an AGV trolley as a transfer tool and combining it with a zero-point positioning mechanism to achieve precise positioning of the tool carrier 4, the efficiency and accuracy of tool transfer are significantly improved. The design of the tool retrieval device 5 allows tools to be quickly retrieved from the tool magazine 1 and installed onto the tool carrier 4, while the introduction of the centering component 6 further enhances the stability and reliability of the entire system. This design not only meets the needs of modern manufacturing for efficient and precise tool management but also reduces the difficulty and cost of equipment maintenance.
