Description

Technical Field

[0001] This utility model relates to the field of tool magazine technology for machining centers, and in particular to a quick-access disc tool magazine mechanism. Background Technology

[0002] A tool magazine system is a device that provides the tool storage and tool changing capabilities required in automated machining processes. Its automatic tool changing mechanism and tool magazine that can store multiple tools have changed the traditional human-based production method. With the control of computer programs, it can complete various machining requirements, such as turning, drilling, boring, and tapping, which greatly shortens the machining time and reduces production costs. This is the biggest feature of the tool magazine system.

[0003] Automatic tool changers are an important component of machining centers, primarily responsible for transferring the required tools from the tool magazine to the spindle clamping mechanism. The structural characteristics of the tool clamping elements and their connection method with the machine tool spindle directly affect the machining performance of the machine tool. The structure of the tool magazine and the working method of the tool exchange device affect the tool changing efficiency of the machine tool. The complexity of the automatic tool changer itself and its related structures directly impacts the overall cost of the machine. Direct-drive motor-driven gearboxes rotating tool selection mechanisms are widely used in CNC machining center tool changing systems.

[0004] Existing technology (see) Figure 5 The indexing cam is located on the side of the tool turret, and the motor is installed horizontally. This occupies a large dimension in the width direction, which affects the overall layout of the tool magazine and causes the external dimensions of the tool magazine to exceed tolerances. The structure needs to be optimized and adjusted to better match the installation of the host machine. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies, optimize the structural layout of existing technologies, and, while ensuring the precise and stable operation of the tool magazine changing system, enable the servo motor to drive the tool rotation, resulting in more stable and precise operation, reducing the installation space required for the mechanism, and facilitating disassembly and assembly.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A quick-access disc tool magazine mechanism includes a tool magazine base, a reducer, a tool disc, a tool sleeve assembly, and a motor. The reducer is installed at the output end of the motor and at the center of both ends of the tool magazine base. The motor is installed at the bottom of the tool magazine base, the tool disc is installed at the output end of the reducer, and the tool sleeve assembly is distributed around the top of the tool disc.

[0008] Furthermore, the motor is mounted on the bottom of the tool magazine base via a bracket, and the output shaft of the motor is connected to the input shaft of the reducer via a coupling.

[0009] Furthermore, the motor is a servo motor with a power of 400W.

[0010] Furthermore, the reducer is fixedly mounted on the reducer mounting positions at both ends of the tool magazine base by bolts.

[0011] Furthermore, the cutter head has a circular disc structure with a mounting hole at its center that matches the output shaft of the reducer. The cutter head is mounted on the output end of the reducer through the mounting hole and is driven to rotate by the reducer.

[0012] Furthermore, the tool holder assembly consists of multiple tool holders evenly distributed around the top of the tool disc, each tool holder is used to hold one tool, and the tool holders are fixedly connected to the tool disc by detachable connectors.

[0013] Furthermore, the detachable connector is a bolt and nut assembly, with threaded holes at the top of the cutter head corresponding to the installation position of each cutter sleeve, and through holes at the bottom of the cutter sleeve. The bolt passes through the through hole at the bottom of the cutter sleeve and is threadedly connected to the threaded hole at the top of the cutter head, and is locked by a nut.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] 1. The tool magazine is installed on the top of the machine tool, which reduces the space required for the installation of the disc tool magazine indexing mechanism;

[0016] Optimized spatial layout: In the prior art, the indexing cam is placed on the side of the tool magazine and the motor is installed horizontally. This layout makes the tool magazine occupy a large size in the width direction. However, this utility model installs the motor at the bottom of the tool magazine base, the reducer at the center of both ends of the tool magazine base, and the tool magazine at the output end of the reducer. This vertical downward layout greatly changes the spatial structure of the tool magazine. By arranging the key components in a reasonable vertical direction, the problem of excessive width dimension caused by horizontally installed motor is avoided, and the space required for the installation of the disc tool magazine's tool magazine indexing mechanism is effectively reduced.

[0017] Matching the host machine installation: In machine tool equipment, space utilization is a key factor. In the existing technology, the tool magazine has an out-of-tolerance external dimension, which makes it difficult to match and install it well with the host machine. This may affect the overall aesthetics and coordination of the machine tool, and may even require additional adjustments to the host machine structure to accommodate the tool magazine. However, the optimized structural layout of this utility model makes the tool magazine external dimension more compact and reasonable, which can better match the installation requirements of the host machine, reduce the installation trouble caused by the tool magazine size problem, and improve the overall assembly efficiency and quality of the machine tool.

[0018] Adaptable to different scenarios: In some processing workshops with limited space or in situations with specific requirements for machine tool layout, existing tool magazines may not meet the needs due to their large size. This utility model reduces the space required for tool magazine installation, making the quick-access disc tool magazine mechanism more flexible to be applied to various processing scenarios, thus improving the versatility and adaptability of the tool magazine.

[0019] 2. The quick-access tool magazine structure facilitates disassembly and maintenance;

[0020] The motor is mounted on the bottom of the tool magazine base via a bracket, and the motor's output shaft is connected to the reducer's input shaft via a coupling. This connection method is simple and reliable; during disassembly, simply loosening the coupling bolts allows the motor to be separated from the reducer. The reducer is bolted to its mounting positions at both ends of the tool magazine base; disassembly is achieved by simply unscrewing the bolts. The tool holder and the tool disc are fixedly connected by a bolt and nut assembly; when the tool holder needs to be replaced or repaired, simply unscrewing the bolts and nuts allows the tool holder to be removed from the tool disc, making the operation convenient and quick.

[0021] 3. The indexing is driven by a servo motor, making the tool changer operation more stable and precise;

[0022] Because servo motors have high-precision position control capabilities, they can precisely control the rotation angle and speed of the output shaft according to the instructions issued by the computer program. During the indexing process of the tool magazine, the servo motor can accurately drive one of the multiple tool holders on the tool turret to rotate to the designated position, ensuring that the tool can accurately dock with the spindle clamping mechanism and achieve precise tool changing operation.

[0033] Example 1

[0034] like Figure 1-4As shown, this utility model provides a technical solution: a quick-access disc tool magazine mechanism. This mechanism has a compact overall design and a reasonable layout of its components, aiming to achieve rapid tool storage and replacement, thereby improving processing efficiency. It includes a tool magazine base 1, a reducer 2, a tool disc 3, a tool holder assembly 4, and a motor 5. The tool magazine base 1 serves as the supporting foundation of the entire mechanism, possessing sufficient strength and stability to withstand various forces generated during operation. The reducer 2 is installed at the output end of the motor 5, its main function being to reduce the speed of the motor 5 and increase the torque to meet the rotational requirements of the tool disc 3. The reducer 2 is installed at the center of both ends of the tool magazine base 1; this installation method ensures the stability of the reducer 2 during operation and reduces vibration. The motor 5 is installed at the bottom of the tool magazine base 1, making reasonable use of the space below the tool magazine base 1, resulting in a more compact overall structure. The tool disc 3 is installed at the output end of the reducer 2 and is the tool-bearing component. Its rotational motion drives the tool holder assembly 4 to rotate, thereby achieving tool switching. The tool holder assembly 4 is distributed around the top of the tool disc 3, capable of accommodating multiple tools to meet the needs of different processing steps.

[0035] Example 2

[0036] like Figure 1-4 As shown, the motor 5 is mounted on the bottom of the tool magazine base 1 by a bracket. The bracket design ensures the stability of the motor 5 installation. The output shaft of the motor 5 is connected to the input shaft of the reducer 2 by a coupling. The coupling has good torque transmission and compensation capabilities for relative displacement between the two shafts, ensuring that the power of the motor 5 is transmitted to the reducer 2 smoothly and reliably.

[0037] Motor 5 is a servo motor. Servo motors have advantages such as high precision, fast response speed and wide speed range. They can accurately control the rotation angle and speed of the cutter head 3 and realize the rapid and accurate switching of tools. Motor 5 has a power of 400W, which can meet the power requirements of the cutter head 3 to drive the tool sleeve assembly 4 to rotate, while ensuring the rational use of energy to a certain extent.

[0038] The reducer 2 is fixedly installed on the reducer mounting positions at both ends of the tool magazine base 1 by bolts. The bolt connection method has the advantages of convenient installation and disassembly and reliable connection, which facilitates the installation, maintenance and replacement of the reducer 2.

[0039] The cutter head 3 has a circular disc structure, which facilitates the uniform distribution and rotation of the cutter. It has a mounting hole at its center that matches the output shaft of the reducer 2. The cutter head 3 is mounted on the output end of the reducer 2 through the mounting hole and is driven to rotate by the reducer 2. The tight fit between the mounting hole and the output shaft of the reducer 2 can ensure the stability of the cutter head 3 during rotation and reduce shaking and deviation.

[0040] The tool holder assembly 4 consists of multiple tool holders evenly distributed around the top of the tool disc 3. Each tool holder is used to hold one tool, and the tool holder is fixedly connected to the tool disc 3 by a detachable connector. This detachable connection method facilitates the installation, replacement and maintenance of the tool holders. When the tool holder is damaged or needs to be replaced with a tool holder of a different specification, the operation can be carried out quickly and conveniently.

[0041] The detachable connector is a bolt and nut assembly. Threaded holes are provided at the top of the cutter head 3 corresponding to the installation position of each cutter sleeve, and through holes are provided at the bottom of the cutter sleeve. Bolts pass through the through holes at the bottom of the cutter sleeve and are threadedly connected to the threaded holes at the top of the cutter head 3, and are locked by nuts. This connection method is simple in structure, low in cost, and reliable in connection, and can meet the fixing requirements between the cutter sleeve and the cutter head 3.

[0042] The working process of this utility model is as follows: When using a quick-access disc tool magazine mechanism, the tools to be used are first installed into the tool sleeves of the tool sleeve group 4. During installation, ensure that the tools are firmly fixed in the tool sleeves to avoid loosening or falling off during rotation.

[0043] Then, start motor 5. Motor 5 transmits power to reducer 2 through coupling. Reducer 2 reduces the speed of motor 5 and increases torque, and then transmits power to cutter head 3, driving cutter head 3 to start rotating. Since the tool sleeve group 4 is distributed around the top of cutter head 3, the rotation of cutter head 3 drives the tool sleeve group 4 to rotate together, so that each tool passes through the designated tool changing position in sequence.

[0044] When a tool needs to be changed, the control system precisely controls the speed and rotation angle of motor 5 according to the preset program, so that the target tool stops accurately at the tool changing position. At this time, the robot or other tool changing device can quickly and accurately remove the current tool and install the tool to be replaced onto the spindle.

[0045] After the tool change operation is completed, motor 5 continues to drive the tool head 3 to rotate, so that the tool magazine mechanism returns to the initial state or prepares for the next tool change operation. Throughout the operation, the servo motor can adjust the speed and direction of rotation in real time according to the instructions of the control system to ensure the rotation accuracy and stability of the tool head 3, thereby realizing fast and accurate tool switching and improving processing efficiency.

[0046] In summary, the disc tool magazine indexing mechanism of this utility model is applied to the BT40-8T disc tool magazine. While ensuring smooth operation of the product, the indexing mechanism has a simple and stable structure, less wear on the mechanism parts, and occupies little space. At the same time, the indexing component of this mechanism is designed with direct motor drive, which makes it easy to disassemble and assemble, facilitates maintenance, and can effectively improve production efficiency.

[0047] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
