Abstract
Description
Technical Field
[0001] This invention relates to the field of machine tool technology, and more particularly to a tool magazine and machine tool. Background Technology
[0002] With the manufacturing industry moving towards automation and efficiency, CNC machine tools are playing an increasingly important role in improving production efficiency and quality. During the machining process on CNC machine tools, the speed and accuracy of tool changing are crucial to ensuring production efficiency and machining precision. Therefore, automatic tool changers are being used more and more widely in CNC machine tools.
[0003] Current automatic tool changer systems for CNC machine tools are mainly divided into two types: disc tool magazines and chain tool magazines. Disc tool magazines have a high capacity but are bulky and prone to tool jamming during tool changing. Chain tool magazines are smaller and more flexible, but existing chain tool magazines have the following problems: complex structure; the use of driven sprockets increases costs and manual debugging time, reducing product quality stability and consistency; the complex electrical and hydraulic structures of the tool holder clamping mechanism and tool moving mechanism lead to high manufacturing and maintenance costs and failure rates; the connection method between the tool and the tool holder is unstable; for example, using support plates and elastic clamps can result in problems such as tool dislodgement, loss of elasticity, or breakage, affecting tool changing accuracy and machining quality; the weight and volume of the tool magazine increase costs and maintenance difficulty, and the increased friction of the chain during tool seeking increases power consumption. Summary of the Invention
[0004] This invention provides a tool magazine to address the defect in related technologies where the tool holder easily falls off during tool changing.
[0005] This invention also provides a machine tool.
[0006] A first aspect of the present invention provides a tool magazine, comprising: A support frame, on which a chain and an unlocking mechanism are provided; A chuck is used to hold a blade sheath, which is used to install a cutting tool.

A pusher mechanism is mounted on the bracket. The pusher mechanism includes a support and a pusher assembly. The pusher assembly is adapted to switch between an extended position and a retracted position, from the retracted position to the extended position. An unlocking mechanism is adapted to unlock the relative position of the blade sheath and the chuck, and the pusher assembly is adapted to push the blade sheath from the chuck to the support, from the extended position to the retracted position. A locking mechanism is adapted to lock the relative position of the blade sheath and the chuck.
[0007] According to one embodiment of the present invention, the chuck has a mounting hole, the blade sleeve has a locking hole, and the locking mechanism includes: A wedge block is installed in the mounting hole, and a wedge hole is provided on the wedge block; A sleeve is installed in the mounting hole; A wedge-shaped shaft is installed in the wedge-shaped hole, and an elastic element is provided between the wedge-shaped shaft and the sleeve. In the retracted position, the elastic element is adapted to press against the sleeve and the wedge-shaped shaft to insert the wedge-shaped shaft into the locking hole. From the retracted position to the pushed-out position, the unlocking mechanism is adapted to act on the wedge-shaped shaft to disengage the wedge-shaped shaft from the locking hole.
[0008] According to one embodiment of the present invention, the unlocking mechanism includes: Mounting base, the mounting base being mounted on the bracket; A first driving component is mounted on the mounting base; A first sliding member is adapted to be guided and installed on the mounting base by a first guide structure and to be drivenly connected to the first driving member. The first sliding member is provided with an unlocking member. From the retracted position to the extended position, the unlocking member is adapted to abut against the wedge shaft to disengage the wedge shaft from the locking hole. From the extended position to the retracted position, the unlocking member is adapted to move away from the wedge shaft.
[0009] According to one embodiment of the present invention, a limiting stage is provided on the wedge shaft, and the limiting stage is adapted to limit the engagement with the wedge hole and the locking hole.
[0010] According to one embodiment of the present invention, a first bearing groove is formed on the opposite first side of the blade sheath, and the claw and the bearing seat are adapted to be inserted into the first bearing groove.
[0011] According to one embodiment of the present invention, the pusher mechanism includes: The fixing seat is mounted on the bracket; A second driving component is mounted on the fixed base; The second sliding member is adapted to be guided and installed on the fixed base by the second guide structure and to be connected to the second driving member in a transmission manner; The third driving component is mounted on the second sliding component; The gripper is connected to the third drive member. During the switching between the retracted position and the extended position, the gripper is adapted to clamp the tool sleeve, and in the retracted position, the gripper is adapted to move away from the tool sleeve.
[0012] According to one embodiment of the present invention, a second bearing groove is formed on the opposite second side surface of the blade sheath, and the gripper is adapted to clamp and engage with the second bearing groove, wherein the first side surface and the second side surface are arranged adjacent to each other.
[0013] According to one embodiment of the present invention, the bracket is provided with a guide rail, and the claw is provided with a rolling element, the rolling element being adapted to be embedded in the guide rail.
[0014] According to one embodiment of the present invention, the system further includes a base and a support leg, wherein the support leg is mounted on the base and the bracket is mounted on the support leg.
[0015] A second aspect of the present invention provides a machine tool including a robot arm and a tool magazine as described above, wherein the robot arm is disposed on one side of the tool magazine and is configured corresponding to a tool changing position on the tool magazine.
[0016] According to the first aspect of the present invention, the tool magazine integrates a chain, chucks, an unlocking mechanism, and a tool-pushing mechanism, realizing an automated tool changing process. When a tool needs to be changed, the tool-pushing mechanism can automatically push the target tool out of the chucks and accurately place it on the carrier, eliminating the need for manual operation and greatly improving production efficiency. The locking mechanism on the chucks and the design of the carrier ensure the stability and safety of the tool during transportation, storage, and tool changing, effectively preventing accidental tool loss or misalignment. Simultaneously, the unlocking mechanism can quickly and accurately release the locking mechanism when needed, cooperating with the tool-pushing mechanism to complete the tool change; the entire process is both fast and reliable. Due to the chain and chuck design, the tool magazine can easily adapt to tools of different sizes and types, exhibiting high flexibility and scalability. Furthermore, by adjusting the length and layout of the chain, the tool storage density and retrieval path can be further optimized, improving overall utilization efficiency. Automated operation reduces the frequency of direct manual intervention in tool changing, lowers the labor intensity of operators, and reduces errors and accidents caused by human factors. In high-speed production environments, automated tool changing systems reduce operators' direct exposure to hazardous areas, thereby improving on-site safety. Simultaneously, stable tool locking and unlocking mechanisms reduce the risk of accidental tool dislodgement. In summary, the tool magazine of this invention, through its innovative automated design, not only improves the efficiency and accuracy of tool changing but also reduces labor costs and safety risks.
[0017] According to a second aspect embodiment of the present invention, the machine tool integrates a robotic arm and a tool magazine, forming a complete automated tool management system. The robotic arm can precisely and quickly dock with the tool change position on the tool magazine to complete actions such as tool gripping, transporting, and changing, realizing unmanned or semi-unmanned operation of the entire machining process. The collaborative work of the robotic arm and the tool magazine significantly shortens tool change time and reduces non-machining waiting time of the machine tool, thereby improving machining efficiency. Furthermore, the high-speed and precise operation of the robotic arm ensures the accuracy and reliability of tool change, avoiding machining errors caused by improper human operation. The robotic arm's design allows it to flexibly adapt to tools of different sizes, types, and weights. Through cooperation with the tool magazine, the robotic arm can easily complete various complex tool change tasks, meeting the diverse needs of the machine tool when machining different workpieces. The robotic arm is positioned on one side of the tool magazine and corresponding to the tool change position. This layout not only saves internal space of the machine tool but also makes the entire tool management system more compact and orderly. At the same time, it facilitates daily maintenance and upkeep by operators. The automated tool changing system reduces direct contact between operators and tools, lowering safety risks caused by human factors. In addition, both the robotic arm and the tool magazine employ strict safety protection measures, such as emergency stop buttons and anti-collision sensors, to ensure safety and stability during high-speed operation.

[0032] The embodiments of the present invention will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and should not be construed as limiting the scope of the invention.
[0033] like Figures 1 to 12 As shown, a first aspect of the present invention provides a tool magazine, comprising: The bracket 100 is equipped with a chain 102 and an unlocking mechanism. The chuck 104 is used to hold the tool holder 106, the tool holder 106 is used to install the tool, the chuck 104 is installed on the chain 102, and the chuck 104 is provided with a locking mechanism, which is used to lock the relative position of the tool holder 106 and the chuck 104, and the unlocking mechanism is used to unlock the relative position of the tool holder 106 and the chuck 104. A pusher mechanism is mounted on a bracket 100. The pusher mechanism includes a support 107 and a pusher assembly. The pusher assembly is adapted to switch between an extended position and a retracted position. From the retracted position to the extended position, an unlocking mechanism is adapted to unlock the relative position of the blade sleeve 106 and the chuck 104. The pusher assembly is adapted to push the blade sleeve 106 from the chuck 104 to the support 107. From the extended position to the retracted position, a locking mechanism is adapted to lock the relative position of the blade sleeve 106 and the chuck 104.
[0034] According to the first aspect of the present invention, the tool magazine integrates a chain 102, a chuck 104, an unlocking mechanism, and a tool pushing mechanism, realizing an automated tool changing process. When a tool needs to be changed, the tool pushing mechanism can automatically push the target tool out of the chuck 104 and accurately place it on the support 107, eliminating the need for manual operation and greatly improving production efficiency. The locking mechanism equipped on the chuck 104 and the setting of the support 107 ensure the stability and safety of the tool during transportation, storage, and tool changing, effectively preventing the tool from accidentally falling off or misaligning. At the same time, the unlocking mechanism can quickly and accurately release the locking mechanism when needed, cooperating with the tool pushing mechanism to complete the tool changing, making the whole process fast and reliable. Due to the design of the chain 102 and the chuck 104, the tool magazine can easily adapt to tools of different sizes and types, and has high flexibility and scalability. In addition, by adjusting the length and layout of the chain 102, the storage density and retrieval path of the tools can be further optimized, improving the overall utilization efficiency. Automated operation reduces the frequency of manual tool changing, lowers the workload of operators, and reduces errors and accidents caused by human factors. In high-speed production environments, automated tool changing systems reduce the opportunity for operators to be directly exposed to hazardous areas, thereby improving the safety of the production site. Simultaneously, a stable tool locking and unlocking mechanism reduces the risk of accidental tool dislodgement. In summary, the tool magazine of this invention, through its innovative automated design, not only improves the efficiency and accuracy of tool changing but also reduces labor costs and safety risks.
[0035] Please continue reading Figures 1 to 12 The tool magazine design of the first aspect of the present invention aims to improve the automation and efficiency of tool storage and replacement.
[0036] The bracket 100 serves as the basic support structure for the entire tool magazine, and a chain 102 and an unlocking mechanism are mounted on the bracket 100. The chain 102 is used to support and move the chuck 104, while the unlocking mechanism is responsible for releasing the locking state between the tool holder 106 and the chuck 104 when needed.
[0037] The chuck 104 is a key component for holding the tool holder 106. It is mounted on the chain 102 and moves with the chain 102. Each chuck 104 is equipped with a locking mechanism to securely lock the tool holder 106 onto the chuck 104 after it is placed on the chuck 104, preventing it from falling off or becoming misaligned during movement or tool changing.
[0038] The tool pushing mechanism is one of the core components of the tool magazine, and it is mounted on the bracket 100. The tool pushing mechanism includes a support 107 and a tool pushing assembly. The support 107 receives the tool sleeve 106 pushed out from the chuck 104. This arrangement allows the support 107 to temporarily support the tool sleeve 106 after it is pushed out, preventing it from falling. More importantly, the support 107 ensures the consistent position of the tool sleeve 106 during tool changing and also prevents the robot arm 152 from applying external force to the support 107 during tool changing.
[0039] The pusher assembly can switch between an extended position and a retracted position. When the pusher assembly is in the extended position, it first triggers the unlocking mechanism to unlock the locking mechanism, thereby unlocking the relative position of the blade holder 106 and the chuck 104. Then, it pushes the blade holder 106 out of the chuck 104 and places it on the support 107. When the pusher assembly returns to the retracted position, it triggers the locking mechanism to relock the relative position of the blade holder 106 and the chuck 104.
[0040] The design of the locking and unlocking mechanisms ensures the stability and reliability of the tool holder 106 during movement and replacement. The locking mechanism securely locks the relative position of the tool holder 106 and the chuck 104, preventing it from falling off or becoming misaligned; while the unlocking mechanism can quickly and accurately release the locking state when needed, providing conditions for the push-tool assembly to be pushed out. In summary, the tool magazine provided by the first aspect of the present invention, through its innovative automated design, not only improves the efficiency and accuracy of tool changing but also reduces labor costs and safety risks, providing strong support for the automation upgrade of modern manufacturing.
[0041] According to one embodiment of the present invention, the chuck 104 is provided with a mounting hole 105, and the blade sheath 106 is provided with a locking hole 108. The locking mechanism includes: A wedge block 110 is installed in the mounting hole 105 and a wedge hole 112 is provided on the wedge block 110; Sleeve 114 is installed in mounting hole 105; A wedge-shaped shaft 116 is installed in a wedge-shaped hole 112, and an elastic element 118 is provided between the wedge-shaped shaft 116 and the sleeve 114. In the retracted position, the elastic element 118 is adapted to press against the sleeve 114 and the wedge-shaped shaft 116 so that the wedge-shaped shaft 116 is inserted into the locking hole 108. From the retracted position to the pushed-out position, the unlocking mechanism is adapted to act on the wedge-shaped shaft 116 so that the wedge-shaped shaft 116 is disengaged from the locking hole 108.
[0042] See Figure 5 In this embodiment of the invention, the locking and unlocking mechanism between the chuck 104 and the blade sheath 106 is implemented in more detail and specifically. Specifically, the chuck 104 is designed with mounting holes 105 for mounting key components of the locking mechanism. The blade sheath 106 is provided with locking holes 108, which cooperate with the locking mechanism on the chuck 104 to achieve a stable locking effect.
[0043] The wedge block 110 is installed in the mounting hole 105 of the chuck 104, and the wedge block 110 has a wedge hole 112. The design of the wedge hole 112 allows the wedge shaft 116 to move linearly relative to the wedge hole 112, which is the key to realizing the locking and unlocking functions.
[0044] Sleeve 114 is also installed in mounting hole 105, forming the basic structure of the locking mechanism together with wedge block 110. The function of sleeve 114 is to provide stable support and guidance for wedge shaft 116.
[0045] A wedge-shaped shaft 116 is installed in a wedge-shaped hole 112, and an elastic element 118 (such as a spring) is provided between it and the sleeve 114. The elastic element 118 provides the necessary elastic force to drive the movement of the wedge-shaped shaft 116. When the unlocking mechanism acts on the wedge-shaped shaft 116, the elastic element 118 is compressed, allowing the wedge-shaped shaft 116 to disengage from the locking hole 108. In the retracted position, the elastic restoring force of the elastic element 118 pushes the wedge-shaped shaft 116 away from the sleeve 114 and inserts it into the locking hole 108 on the tool holder 106, thereby locking the tool holder 106 with the chuck 104.
[0046] When the pusher mechanism moves from the retracted position to the extended position, the unlocking mechanism acts on the wedge shaft 116. That is, the unlocking mechanism directly pushes the wedge shaft 116 so that the wedge shaft 116 overcomes the elastic restoring force of the elastic element 118 and disengages the wedge shaft 116 from the locking hole 108.
[0047] When the pusher mechanism moves from the push position to the retracted position, the unlocking mechanism moves away from the wedge shaft 116. Under the elastic restoring force of the elastic element 118, the wedge shaft 116 is pressed downward and inserted into the locking hole 108, thereby locking the tool sleeve 106 with the chuck 104.
[0048] The combination of wedge block 110, sleeve 114, and wedge shaft 116, along with the use of elastic element 118, ensures that the locking and unlocking process is both precise and reliable. The special shape of the wedge hole 112 ensures the stability and directionality of the wedge shaft 116 during movement, while the elasticity of the elastic element 118 guarantees the firmness and automation of the lock. This locking and unlocking mechanism works closely with the pusher mechanism to achieve highly efficient automation of tool changing. When the pusher mechanism moves, the unlocking mechanism automatically acts on the wedge shaft 116 to complete the unlocking action; when the pusher mechanism resets, the elastic element 118 automatically pushes the wedge shaft 116 back into the locking hole 108 to relock. Due to the standardized design of the mounting hole 105 and locking hole 108, this locking and unlocking mechanism can be applied to different sizes and types of tool sleeves 106 and chucks 104, exhibiting strong adaptability and scalability. The automated locking and unlocking process reduces the need for manual intervention and lowers the safety risks caused by improper human operation. At the same time, the robust locking mechanism ensures the stability of the tool during movement and replacement, preventing accidental drop or collision.
[0049] Of course, if the unlocking mechanism malfunctions, the wedge shaft 116 can be manually operated to move the wedge shaft 116 away from the locking hole 108, thereby completing the unlocking action.
[0050] According to one embodiment of the present invention, the unlocking mechanism includes: Mounting base 120 is mounted on bracket 100; The first drive component 122 is mounted on the mounting base 120; The first sliding member 124 is adapted to be guided and installed on the mounting base 120 by the first guide structure and to be connected to the first driving member 122 in a transmission manner. The first sliding member 124 is provided with an unlocking member 126. From the retracted position to the extended position, the unlocking member 126 is adapted to press against the wedge shaft 116 so that the wedge shaft 116 is disengaged from the locking hole 108. From the extended position to the retracted position, the unlocking member 126 is adapted to move away from the wedge shaft 116.
[0051] See Figure 7 and Figure 10 In this embodiment of the invention, the unlocking mechanism is further refined, including key components such as mounting base 120, first driving member 122, first sliding member 124 and unlocking member 126. These components work together to achieve precise unlocking between the blade sheath 106 and the chuck 104.
[0052] Mounting base 120 serves as the basic support structure for the unlocking mechanism, and is securely mounted on bracket 100. It provides a stable mounting platform for the first drive member 122 and the first sliding member 124.
[0053] The first driving member 122 is mounted on the mounting base 120 and is the power source for the unlocking mechanism. It can be a motor, cylinder, or other device capable of generating linear or rotary motion. The first driving member 122 is connected to the first sliding member 124 through a transmission device (such as gears, chain 102, belt, etc.) to drive its movement.
[0054] The first sliding member 124 is guided and mounted on the mounting base 120 by a first guide structure (such as a guide rail 144, a slide groove, etc.) to ensure its stability and accuracy during movement. The first sliding member 124 is connected to the first driving member 122 and can move accordingly in response to the output of the first driving member 122.
[0055] The unlocking element 126, mounted on the first sliding member 124, is the key component for actually performing the unlocking action. When the first sliding member 124 moves from the retracted position to the extended position under the drive of the first driving member 122, the unlocking element 126 moves accordingly and abuts against the wedge-shaped shaft 116. This abutting action overcomes the elastic restoring force of the elastic member 118, causing the wedge-shaped shaft 116 to disengage from the locking hole 108 of the blade sleeve 106, thereby achieving unlocking. Conversely, when the first sliding member 124 moves from the extended position to the retracted position, the unlocking element 126 moves away from the wedge-shaped shaft 116 and no longer abuts it. At this time, the elastic member 118 pushes the wedge-shaped shaft 116 back into the locking hole 108, achieving relocking.
[0056] The precise cooperation of the first driving component 122, the first sliding component 124, and the unlocking component 126 enables precise control of the wedge-shaped shaft 116. During the unlocking process, the unlocking component 126 accurately abuts against the wedge-shaped shaft 116 and disengages it from the locking hole 108, avoiding problems caused by incomplete or excessive unlocking. The unlocking mechanism works closely with components such as the push-tool mechanism to achieve highly efficient automation of the tool changing process. When a tool needs to be changed, the unlocking mechanism automatically performs the unlocking action, releasing the tool without manual intervention. The automated unlocking mechanism significantly shortens tool changing time and reduces non-processing waiting time for the machine tool. This helps improve production efficiency and reduce production costs. Due to the use of a precision mechanical structure and transmission device, the unlocking mechanism has high reliability and stability. This helps reduce non-processing time caused by equipment failure and extend the service life of the equipment. The automated unlocking process reduces the risk of manual operation and improves the safety of the production site. At the same time, the robust locking and unlocking mechanism also ensures the stability of the tool during movement and replacement, preventing accidents.
[0057] According to one embodiment of the present invention, a limiting stage 128 is provided on the wedge shaft 116, and the limiting stage 128 is adapted to limit the engagement with the wedge hole 112 and the locking hole 108.
[0058] See Figure 5 In this embodiment of the invention, a limiting platform 128 is specially added to the wedge shaft 116, which further enhances the stability and reliability of the locking and unlocking mechanism.
[0059] The limiting platform 128 is one or more protrusions on the wedge shaft 116, whose size and position are carefully designed to ensure a good limiting fit with the wedge hole 112 and the locking hole 108 on the tool holder 106.
[0060] When the wedge shaft 116 is installed in the wedge hole 112, the limiting stage 128 will contact the edge or a specific position of the wedge hole 112, forming a certain constraint and limitation. This fit helps to prevent the wedge shaft 116 from moving or rotating too much within the wedge hole 112, thereby maintaining its stability and accuracy during movement.
[0061] In the locked state, the wedge shaft 116 is inserted into the locking hole 108 of the tool holder 106, at which time the limiting stage 128 interacts with the edge or internal structure of the locking hole 108. This limiting fit not only enhances the locking firmness, but also prevents the wedge shaft 116 from accidentally dislodging from the locking hole 108 when subjected to external force.
[0062] The design of the limiting stage 128 makes the position of the wedge shaft 116 more stable in the wedge hole 112 and the locking hole 108, reducing loosening or displacement caused by vibration or impact. This helps maintain the stability of the tool during changeover and storage. The limiting engagement of the limiting stage 128 and the locking hole 108 further limits the excessive extension of the wedge shaft 116 without the tool sleeve 106, preventing interference between the wedge shaft 116 and the unlocking member 126.
[0063] According to one embodiment of the present invention, a first bearing groove 130 is formed on the opposite first side of the blade sheath 106, and the claw 104 and the bearing seat 107 are adapted to be inserted into the first bearing groove 130.
[0064] See Figure 6 In this embodiment of the invention, the design of the blade sleeve 106 is further optimized, especially by forming a first bearing groove 130 on the first side, which achieves a tighter and more stable insertion fit with the claw 104 and the bearing seat 107.
[0065] The first bearing groove 130 is a recess specifically created on the first side of the tool holder 106. Its shape, size, and position match the shapes of the chuck 104 and the support 107 to ensure a tight fit between the chuck 104 and the support 107. The creation of the first bearing groove 130 not only enhances the connection strength between the tool holder 106 and the chuck 104 and the support 107, but also improves the stability and reliability of the entire tool system.
[0066] When the jaw 104 and the support base 107 are engaged, the jaw 104 inserts into the first support groove 130 along a specific direction. Because the shape and size of the support groove match the jaw 104 and the support base 107, they can fit together tightly to form a stable mechanical connection. This engagement method not only simplifies the installation process but also improves the accuracy and efficiency of installation.
[0067] The plug-in engagement between the first bearing groove 130 and the jaws 104 and the bearing seat 107 significantly enhances the connection strength between them. This plug-in engagement makes the installation of the jaws 104 and the bearing seat 107 simpler and faster. By adjusting the shape and size of the first bearing groove 130, it can be adapted to different specifications and types of jaws 104 and bearing seats 107. This design improves the compatibility and scalability of the tooling system, allowing users to select appropriate components for use according to their actual needs.
[0068] According to one embodiment of the present invention, the pusher mechanism includes: Mounting base 132 is installed on bracket 100; The second drive component 134 is mounted on the fixed base 132; The second sliding member 136 is adapted to be guided and installed on the fixed base 132 by the second guide structure and to be connected to the second driving member 134 in a transmission manner. The third driving component 138 is mounted on the second sliding component 136; The gripper 140 is connected to the third drive member 138. During the switching between the retracted position and the extended position, the gripper 140 is adapted to clamp the tool sleeve 106. In the retracted position, the gripper 140 is adapted to move away from the tool sleeve 106.
[0069] See Figures 8 to 10 In this embodiment of the invention, the pusher mechanism is designed as a highly integrated component for automatic tool changing. The mechanism mainly includes key components such as a fixed base 132, a second drive member 134, a second sliding member 136, a third drive member 138, and a gripper 140.
[0070] The fixed base 132 serves as the basic support structure for the pusher mechanism and is securely mounted on the bracket 100. The fixed base 132 provides a stable mounting platform for the second drive member 134, the second sliding member 136, and subsequent components.
[0071] The second driving member 134 is mounted on the fixed base 132 and is the main power source for the pusher mechanism. It can be a motor, cylinder or other power device. The second driving member 134 is connected to the second sliding member 136 through a transmission device (such as gears, chain 102, belt, etc.) to drive it to move in a specific direction.
[0072] The second sliding member 136 is guided and mounted on the fixed base 132 by a second guide structure (such as guide rail 144, slide groove, etc.) to ensure its stability and accuracy during movement. The second sliding member 136 is connected to the second driving member 134 and can move accordingly in response to the output of the second driving member 134.
[0073] The third drive element 138 is mounted on the second sliding element 136 and is used to drive the opening and closing of the gripper 140 or other actions of the gripper 140. The third drive element 138 can also be a motor, a cylinder, or other device capable of generating clamping force. The third drive element 138 is connected to the gripper 140 in a transmission manner, and the clamping and releasing of the tool sleeve 106 can be achieved by controlling its output.
[0074] The gripper 140 is connected to the third drive member 138 and is the component that actually performs the clamping and releasing actions of the tool holder 106. During the process of the pusher mechanism moving from the retracted position to the extended position, the gripper 140 clamps the tool holder 106 to ensure its stable movement; while in the retracted position, the gripper 140 moves away from the tool holder 106 to perform the next clamping operation.
[0075] The pusher mechanism achieves highly efficient automation of the tool changing process through integrated design. When a tool change is needed, the pusher mechanism automatically clamps the tool holder 106 and moves it to the designated position, completing the entire changeover process without manual intervention. Automated tool changing significantly reduces machine tool downtime and improves production efficiency. Operators only need to monitor and maintain the machine tool when necessary to ensure continuous operation. Through a precise guiding structure and a stable power transmission system, the pusher mechanism ensures high stability and accuracy during movement. Automated tool changing reduces the workload of operators and lowers the risk of physical fatigue and work-related injuries caused by prolonged repetitive labor. The pusher mechanism has high reliability and durability, which helps reduce downtime due to equipment failure and extend the service life of the equipment.
[0076] According to one embodiment of the present invention, a second bearing groove 142 is formed on the opposite second side surface of the blade sheath 106, and the gripper 140 is adapted to clamp and engage with the second bearing groove 142, wherein the first side surface and the second side surface are arranged adjacent to each other.
[0077] See Figure 6In this embodiment of the invention, the design of the blade sheath 106 is further optimized, especially by adding a second bearing groove 142 on its opposite second side. This design enables the gripper 140 to achieve a more stable and precise clamping engagement with the blade sheath 106.
[0078] The second bearing groove 142 is a groove formed on the second side of the tool holder 106. Its shape, size, and position are adapted to the gripper 140 to ensure a good clamping fit. The second bearing groove 142 not only enhances the connection strength between the gripper 140 and the tool holder 106, but also improves the stability and reliability of the entire tool changing process.
[0079] When the gripper 140 of the pusher mechanism needs to grip the tool sleeve 106, it moves along a specific direction to the position of the second bearing groove 142 and makes close contact with the edge or specific structure of the second bearing groove 142 through its gripping surface. This gripping engagement method allows the gripper 140 to firmly grip the tool sleeve 106, preventing it from falling off or shaking during movement.
[0080] It is worth noting that the first and second sides are arranged adjacent to each other. This layout design facilitates smooth clamping and release between the gripper 140 and the tool holder 106. When the gripper 140 moves from the retracted position to the extended position, the chuck 104 disengages from the first bearing groove 130, and the gripper 140 clamps the second bearing groove 142 to move the tool holder 106 onto the support seat 107. At this time, the support seat 107 and the first bearing groove 130 are mutually clamped and adapted. When the gripper 140 moves from the extended position to the retracted position, the gripper 140 clamps the second bearing groove 142 to disengage the first bearing groove 130 from the support seat 107. When the gripper 140 moves to the retracted position, the chuck 104 and the first bearing groove 130 are mutually clamped and adapted.
[0081] The design of the second bearing groove 142 makes the clamping between the gripper 140 and the tool holder 106 more stable and reliable. This stable clamping can resist the vibration and impact generated during tool movement, ensuring a smooth tool change process. Through the precisely designed second bearing groove 142 and the clamping surfaces of the gripper 140, high-precision clamping between the gripper 140 and the tool holder 106 can be achieved. Through the optimized design of the tool holder 106 and the gripper 140, the overall performance of the entire tool changing system is improved. This includes increased production efficiency, reduced labor intensity, enhanced equipment reliability, and extended equipment lifespan.
[0082] According to one embodiment of the present invention, a guide rail 144 is provided on the bracket 100, and a rolling element 146 is provided on the claw 104, the rolling element 146 being adapted to be embedded in the guide rail 144.
[0083] See Figure 3 In this embodiment of the invention, to further improve the stability and accuracy of the tool magazine, a guide rail 144 is designed on the bracket 100, while a rolling element 146 is provided on the chuck 104. The design of the rolling element 146 allows it to be embedded in the guide rail 144, thereby achieving smooth and stable movement.
[0084] The guide rail 144 is a linear guide device mounted on the bracket 100, providing a precise movement path to ensure that the chuck 104 can move in a predetermined direction.
[0085] Rolling elements 146 are mounted on the jaws 104, and their shape and size match the guide rail 144, allowing them to be embedded in and roll along the guide rail 144. The design of the rolling elements 146 reduces friction and wear between the jaws 140 and the guide rail 144 during movement, thereby improving movement efficiency and accuracy. In addition, the rolling elements 146 also have a certain load-bearing capacity and cushioning effect, protecting the guide rail 144 from direct impact and damage.
[0086] When the chuck 104 needs to move, the rolling element 146 rolls along the guide rail 144 to move the chuck 104 in a predetermined direction. Because the fit between the rolling element 146 and the guide rail 144 is tight and smooth, the movement of the chuck 104 is very stable and precise. This fit also helps reduce vibration and noise, improving the overall operating quality of the tool magazine.
[0087] The design of the guide rail 144 and rolling element 146 enables the chuck 104 to maintain high stability during movement. The tight fit between the rolling element 146 and the guide rail 144 ensures that the chuck 104 can move along a precise path. This high-precision movement helps improve the accuracy and reliability of tool changes. The design of the rolling element 146 reduces friction and wear between the chuck 104 and the guide rail 144 during movement. This helps extend the service life of the guide rail 144 and the rolling element 146 and reduces maintenance costs. Because the rolling element 146 reduces friction and wear, the movement of the chuck 104 is smoother and more efficient. This helps improve the operating efficiency of the entire tool change system and shorten the time required for tool changes. The smooth fit between the guide rail 144 and the rolling element 146 helps reduce vibration and noise generation. This helps improve the working environment and protect the hearing health of operators.
[0088] According to one embodiment of the present invention, the system further includes a base 148 and a support leg 150, wherein the support leg 150 is mounted on the base 148 and the bracket 100 is mounted on the support leg 150.
[0089] See Figure 1In this embodiment of the invention, a base 148 and a support leg 150 are introduced to provide a stable and adjustable mounting base. This design allows the entire tool magazine to be stably mounted in the working environment and adjusted in height or position as needed.
[0090] The base 148 is the lowest structure of the entire system, providing sufficient support area and weight to ensure the system can be placed stably on the ground. The base 148 is typically made of sturdy and durable metal or alloy materials to withstand the weight of the entire system and any vibrations that may occur.
[0091] The support legs 150 are vertical components connecting the base 148 and the bracket 100. They are mounted on the base 148 and extend upwards to support the bracket 100. The number, position, and length of the support legs 150 can be designed according to actual needs to ensure that the bracket 100 can be stably installed and reach the required height. The design of the support legs 150 should also take into account adjustment functions so that the accuracy of the system can be fine-tuned when needed.
[0092] The bracket 100 is the main structure supporting the pusher mechanism and other key components. In this embodiment, the bracket 100 is mounted on the support leg 150 and fixed by bolts, welding, or other fastening methods. This mounting method ensures the stability and rigidity of the bracket 100, enabling it to withstand the forces and torques generated during the movement and clamping of the tool.
[0093] The base 148 and support leg 150 provide a stable mounting foundation for the entire tool changing system. This stability helps reduce vibration and misalignment during operation. The adjustability of the support leg 150 ensures assembly accuracy. This modular design improves installation efficiency and reduces installation difficulty. The base 148 and support leg 150 are typically made of robust and durable materials, capable of withstanding long-term use and potential impacts, extending the system's lifespan. A stable mounting foundation helps reduce safety hazards caused by vibration or misalignment during system operation.
[0094] A second aspect of the present invention provides a machine tool including a robot arm 152 and a tool magazine as described above. The robot arm 152 is disposed on one side of the tool magazine and is configured corresponding to the tool changing position on the tool magazine.
[0095] See Figure 1According to the second aspect of the present invention, the machine tool integrates a robotic arm 152 and a tool magazine, forming a complete automated tool management system. The robotic arm 152 can precisely and quickly dock with the tool change position on the tool magazine to complete actions such as tool gripping, transporting, and changing, realizing unmanned or semi-unmanned operation of the entire tool changing process. The collaborative work of the robotic arm 152 and the tool magazine significantly shortens the tool changing time and reduces the machine tool's non-machining waiting time, thereby improving machining efficiency. Furthermore, the high-speed and precise operation of the robotic arm 152 also ensures the accuracy and reliability of tool changing. The design of the robotic arm 152 allows it to flexibly adapt to tools of different sizes, types, and weights. Through cooperation with the tool magazine, the robotic arm 152 can easily complete various complex tool changing tasks, meeting the diverse needs of the machine tool when machining different workpieces. The robotic arm 152 is located on one side of the tool magazine and corresponds to the tool change position. This layout not only saves internal space of the machine tool but also makes the entire tool management system more compact and orderly. At the same time, it also facilitates daily maintenance and upkeep by operators. The automated tool changing system reduces direct contact between operators and tools, lowering safety risks caused by human error. Furthermore, both the robotic arm 152 and the tool magazine employ stringent safety measures, such as emergency stop buttons and anti-collision sensors, ensuring safety and stability during high-speed operation.
