Description

Technical Field

[0001] This invention belongs to the field of central tool magazine technology, and specifically relates to a rapidly positioned array-distributed central tool magazine and its control method. Background Technology

[0002] A tool magazine system is a device that provides the tool storage and 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.

[0003] A search revealed that Chinese Patent Publication No. CN118081447B, published on July 2, 2024, discloses a horizontal central tool magazine with self-adjusting tool retrieval function and its control method. The invention includes a central tool magazine housing, with a tool sleeve adjustment assembly installed on the inner bottom wall of the housing. Two sets of cleaning and sharpening assemblies are symmetrically installed on the tool sleeve adjustment assembly, and a drive control assembly is connected to the tool sleeve adjustment assembly. After determining the shape of the tool, the invention activates a third motor to drive two sets of elastic rectangular plates to fix and limit the tool. Subsequently, a fourth motor is activated to rotate and shift the elastic rectangular plates, so that the contact position between the tool and the elastic rectangular plates is located at the center of the plates. Therefore, under the mutual compression of the tool and the two sets of support blocks, the elastic rectangular plates begin to deform, effectively limiting and stabilizing irregular tools. This improves the tool clamping stability within the central tool magazine and enhances the self-adjusting effect of the tool retrieval function.

[0004] However, this central tool magazine still has the following drawbacks:

[0005] When existing central tool magazines are used in tool changing operations on multi-machine tool production lines, if the tools of one or more machine tools break or are damaged, the central tool magazine cannot promptly replace the corresponding machine tools. Moreover, the tool changing process is cumbersome and lacks efficiency and convenience. Summary of the Invention

[0013] Furthermore, a multi-axis robotic arm is provided on the top of the movable seat; a transfer clamp is connected to the output end of the multi-axis robotic arm; two sets of guide blocks are symmetrically provided on the inner walls of both sides of the movable seat, and each set of guide blocks is slidably connected in several sets of guide grooves.

[0014] Furthermore, the tool transfer assembly includes a second housing; one end of the second housing extends into the vacuum tool storage chamber and is provided with a first sealing plate; a second sealing plate is provided at the end of the second housing away from the first housing; an electric slide is provided on the bottom inner wall of the second housing; a mounting ring is drivenly connected to the output end of the electric slide; two sets of second electric push rods are symmetrically provided on the inner wall of the mounting ring; a set of tool body fixing plates is drivenly connected to the output end of each set of second electric push rods.

[0015] Furthermore, the tool-retrieving assembly includes a guide post; a second sliding groove is formed on the outer wall of the guide post; a lead screw is provided in the second sliding groove; and a guide ring is movably sleeved on the outer wall of the guide post.

[0018] A control method for a rapidly positioned array-distributed central tool magazine, the control method comprising:

[0019] The cutting tools of one or more groups of machine tools on a multi-machine tool production line are damaged;

[0020] The corresponding distributed simple tool magazine senses and immediately replaces the damaged tool;

[0021] The corresponding distributed simplified tool magazine will send the replacement tool model to the closed main tool magazine;

[0022] The tool-retrieving mechanism is controlled to transfer the corresponding tool into the tool transfer assembly;

[0023] The tool transfer assembly controls the transfer of tools to the outside of the enclosed main tool magazine;

[0024] The control splicing conveyor mechanism transfers the cutting tools to the corresponding distributed simple tool magazine.

[0025] The beneficial effects of this invention are:

[0026] 1. When one or more sets of tools on a multi-machine production line are damaged, the corresponding distributed simple tool magazine will immediately replace the damaged set of tools. At the same time, the distributed simple tool magazine will send the replacement tool model to the closed main tool magazine. The closed main tool magazine will take out the corresponding tool and replenish it with the splicing conveyor mechanism to ensure the timeliness of the next tool replacement. The tool replacement process is simple and quick, which improves the efficiency and convenience of tool replacement in the central tool magazine.

[0027] 2. By energizing several sets of electromagnets to generate magnetism, and then placing several sets of mounting plates sequentially into a set of mounting slots, the electromagnets attract several sets of magnetic metal blocks, thereby fixing several sets of tool fixing components in the vacuum tool storage chamber. At the same time, after the sealing door is closed, the limiting posts at both ends of the mounting plates move through the corresponding first limiting slot and second limiting slot, respectively. This ensures that when the central tool magazine is powered off, the tools will not fall due to the demagnetization of the electromagnets. When the tool storage function of the central tool magazine malfunctions, the corresponding mounting plates can be disassembled and repaired without stopping the machine, thus improving the maintenance efficiency of the central tool magazine.

[0028] 3. By fixing several sets of various types of cutting tools onto several sets of cutting tool fixing assemblies, which are distributed in several sets of mounting slots in a circular array, once all the cutting tools are completely fixed, the first electric push rod and connecting device are controlled to drive the sealing door to seal the vacuum tool storage chamber. Then, the air in the vacuum tool storage chamber is evacuated, so that the cutting tools are stored in a vacuum state. When retrieving the cutting tools, the cutting tools do not need to be rotated; the cutting tool retrieval assembly will take out the corresponding cutting tools. This not only improves the tool storage effect of the central tool magazine but also avoids greater losses caused by accidental contact when the cutting tools rotate, thus improving the safety of the central tool magazine.

[0029] 4. By connecting and fixing the corresponding number of guide rails in sequence, several sets of first slides are kept in a connected state. Then, the moving seat is transferred from one set of guide rails on the edge to the inside of the guide rail. Then, limit devices are installed on the guide rails at both ends to prevent the moving seat from derailing. In use, the moving seat is controlled to drive the multi-axis robotic arm and the transfer fixture to transport the tool. This allows the central tool magazine to not only adjust the transport stroke autonomously according to the span of the multi-machine production line, but also improves the convenience of installation.

[0030] Other features and advantages of the invention will be set forth in the description which follows, and will be apparent in part from the description, or may be learned by practicing the invention.

Detailed Implementation

[0043] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0044] This invention provides a rapidly positioning array-distributed central tool magazine, comprising a closed main tool magazine 1, a modular conveying mechanism 3, and several sets of distributed simplified tool magazines 2 arranged in a rectangular array. For example,... Figure 1 As shown, the splicing conveyor 3 is located at the output end of the enclosed main tool magazine 1, and several sets of the distributed simple tool magazines 2 are symmetrically arranged on both sides of the splicing conveyor 3.

[0045] During installation, the number of distributed simple tool magazines 2 and the length of the splicing conveyor mechanism 3 are adjusted according to the number and span of the multi-machine tool production line. The distributed simple tool magazines 2 only have simple tool changing functions and store a small number of tools required by the corresponding machine tools. When the tools of one or more machine tools are damaged, the corresponding distributed simple tool magazines 2 will replace the damaged tools. At the same time, the distributed simple tool magazines 2 will send the replacement tool model to the closed main tool magazine 1. The closed main tool magazine 1 will take out the corresponding tool and, together with the splicing conveyor mechanism 3, replenish the corresponding tool, ensuring the timeliness of the next tool replacement and improving the efficiency and convenience of tool changing of the central tool magazine.

[0046] For example, such as Figure 2 , Figure 3 and Figure 4 As shown, the enclosed main tool magazine 1 includes a first housing 101; a support base 102 is provided at the bottom of the first housing 101; a vacuum tool storage chamber 108 is provided inside the first housing 101; the inner wall of the vacuum tool storage chamber 108 away from the splicing conveying mechanism 3 is an open structure; two sets of first electric push rods 103 are provided at the top of the first housing 101; a connecting device 104 is connected to the output end of the two sets of first electric push rods 103; a sealing door 105 is provided on the connecting device 104; the sealing door 105 movably seals the vacuum tool storage chamber 108; several sets of mounting slots 111 are arranged in a circular array on the inner wall of the vacuum tool storage chamber 108; each set of mounting slots 111 is provided with a tool fixing assembly 1. 10; A tool retrieval assembly 109 is provided inside the vacuum tool storage chamber 108; A first motor 107 is provided on the side wall of the first housing 101 near the splicing conveying mechanism 3; The output end of the first motor 107 is connected to the tool retrieval assembly 109 in a transmission connection; A tool transfer assembly 106 is provided on the side wall of the first housing 101 near the splicing conveying mechanism 3; Several sets of electromagnets 112 are provided at equal intervals on the inner wall of the mounting groove 111 away from the tool retrieval assembly 109; Several sets of first limiting grooves 113 are arranged in a ring array on the inner wall of the closed door 105 near the vacuum tool storage chamber 108; Several sets of second limiting grooves 114 are arranged in a ring array on the inner wall of the vacuum tool storage chamber 108 near the first motor 107.

[0047] Several sets of various types of cutting tools are fixed on several sets of cutting tool fixing assemblies 110. The cutting tool fixing assemblies 110 are distributed in several sets of mounting slots 111 in a ring array. After all the cutting tools are completely fixed, the first electric push rod 103 and the connecting device 104 are controlled to drive the sealing door 105 to seal the vacuum tool storage chamber 108. Then, the air in the vacuum tool storage chamber 108 is evacuated, so that the cutting tools are stored in a vacuum state. When the cutting tool is retrieved, the cutting tools do not need to be rotated. The cutting tool retrieval assembly 109 retrieves the corresponding cutting tools. This not only improves the tool storage effect of the central tool magazine, but also avoids greater losses caused by accidental contact when the cutting tools are rotated, thus improving the safety of the central tool magazine.

[0048] For example, such as Figure 5 and Figure 6 As shown, the splicing conveying mechanism 3 includes several sets of guide rails 301 connected in sequence; each set of guide rails 301 has several sets of support columns 302 at its bottom edge; each set of guide rails 301 has a set of first sliding grooves 303 at its top; both ends of each set of first sliding grooves 303 are open structures; the several sets of first sliding grooves 303 are connected in sequence; two sets of guide grooves 304 are symmetrically opened on the inner walls of both sides of each set of first sliding grooves 303; a movable seat 305 is slidably connected in the several sets of first sliding grooves 303; the movable seat 305... A multi-axis robotic arm 306 is provided at the top; a transfer clamp 307 is driven to the output end of the multi-axis robotic arm 306; two sets of guide blocks 308 are symmetrically provided on the inner walls of both sides of the movable seat 305, and each set of guide blocks 308 is slidably connected in a number of corresponding guide grooves 304; a set of racks 309 is provided on the bottom inner wall of each set of first sliding grooves 303; a second motor 310 is provided inside the movable seat 305; a gear 311 is driven to the output end of the second motor 310; the gear 311 is meshed with the rack 309.

[0049] During installation, the span of the multi-machine tool production line is first measured. Then, a corresponding number of guide rails 301 are selected and connected and fixed in sequence to keep several sets of first slide grooves 303 connected. Then, the moving seat 305 is transferred from one set of guide rails 301 at the edge to the inside of the guide rails 301. Limiting devices are then installed on the guide rails 301 at both ends to prevent the moving seat 305 from derailing. In use, the second motor 310 is controlled to drive the gear 311 to rotate. Under the meshing connection between the gear 311 and the rack 309, the moving seat 305 drives the multi-axis robotic arm 306 and the transfer fixture 307 to transport the tool. This allows the central tool magazine to not only adjust the transport stroke autonomously according to the span of the multi-machine tool production line, but also improves the convenience of installation.

[0050] For example, such as Figure 7As shown, the tool transfer assembly 106 includes a second housing 1061; one end of the second housing 1061 extends into the vacuum tool storage chamber 108 and is provided with a first sealing plate 1062; a second sealing plate 1063 is provided at the end of the second housing 1061 away from the first housing 101; an electric slide 1064 is provided on the bottom inner wall of the second housing 1061; a mounting ring 1065 is drivenly connected to the output end of the electric slide 1064; two sets of second electric push rods 1066 are symmetrically provided on the inner wall of the mounting ring 1065; a set of tool body fixing plates 1067 are drivenly connected to the output end of each set of second electric push rods 1066.

[0051] During the tool transfer process, the first sealing plate 1062 is first opened, then the tool retrieval assembly 109 is controlled to transfer the corresponding tool between the two sets of tool body fixing plates 1067. Then, the two sets of second electric push rods 1066 are controlled to drive the two sets of tool body fixing plates 1067 to clamp the tool. Then, the tool retrieval assembly 109 is controlled to release the clamp on the tool and reset. Then, the first sealing plate 1062 is controlled to close, then the second sealing plate 1063 is controlled to open, and then the electric slide 1064 is controlled to drive the mounting ring 1065 to transfer the tool to the outside of the first housing 101. The splicing conveyor mechanism 3 then transfers the tool to the corresponding distributed simple tool magazine 2. Throughout the entire tool transfer process, the vacuum tool storage chamber 108 remains sealed, preventing external impurities from entering and corroding the tool, thereby improving the tool's service life.

[0052] For example, such as Figure 8 As shown, the tool-retrieving assembly 109 includes a guide post 1091; a second sliding groove 1092 is formed on the outer wall of the guide post 1091; a lead screw 1093 is provided in the second sliding groove 1092; the output end of the first motor 107 is connected to the lead screw 1093; a guide ring 1094 is movably sleeved on the outer wall of the guide post 1091; a slider 1095 is provided on the inner wall of the guide ring 1094; the slider 1095 is slidably connected in the second sliding groove 1092 and threadedly connected to the lead screw 1093; a rotating ring 1096 is provided on the outer wall of the guide ring 1094; a third electric push rod 1097 is provided on the outer wall of the rotating ring 1096; a tool-retrieving clamp 1098 is connected to the output end of the third electric push rod 1097.

[0053] During the tool retrieval process, the enclosed main tool magazine 1 receives a signal from the corresponding distributed simplified tool magazine 2. First, it controls the first motor 107 to drive the lead screw 1093 to rotate. With the lead screw 1093 and the slider 1095 threadedly connected, the slider 1095 drives the guide ring 1094 to move to the corresponding horizontal position. Then, it controls the rotating ring 1096 to drive the third electric push rod 1097 to rotate, so that the tool retrieval fixture 1098 is aligned with the tool to be retrieved. Then, it controls the third electric push rod 1097 to drive the tool retrieval fixture 1098 to remove the tool. Finally, it controls the tool to be transferred into the tool transfer assembly 106. During the entire process, several sets of tools do not need to rotate, avoiding greater losses caused by accidental tool rotation.

[0054] For example, such as Figure 9 and Figure 10 As shown, the tool fixing assembly 110 includes a mounting plate 1101; the mounting plate 1101 is installed in a corresponding set of mounting slots 111; a plurality of tool sleeves 1102 are evenly spaced on the side wall of the mounting plate 1101 near the tool taking assembly 109; two sets of limiting posts 1103 are symmetrically arranged on the two side walls of the mounting plate 1101; the two sets of limiting posts 1103 are respectively movably inserted into a corresponding set of first limiting slots 113 and second limiting slots 114; a plurality of magnetic metal blocks 1104 are evenly spaced on the side wall of the mounting plate 1101 away from the tool sleeves 1102; each set of magnetic metal blocks 1104 is movably attached to a corresponding set of electromagnets 112.

[0055] A number of mounting slots 111 are arranged in a circular array on the inner wall of the first housing 101. The mounting slots 111 have a rectangular cross-section. A number of electromagnets 112 are energized to generate magnetism. Then, a number of mounting plates 1101 are placed in a set of mounting slots 111 in sequence, so that the electromagnets 112 attract a number of magnetic metal blocks 1104. This fixes the tool fixing components 110 in the vacuum tool storage chamber 108. After the sealing door 105 is closed, the limiting posts 1103 at both ends of the mounting plates 1101 move through a set of first limiting slots 113 and second limiting slots 114 respectively. This prevents the tools from falling when the central tool magazine is de-energized due to the de-energization and demagnetization of the electromagnets 112. When the tool storage function of the central tool magazine malfunctions, the corresponding mounting plates 1101 can be disassembled and repaired without stopping the machine, which improves the maintenance efficiency of the central tool magazine.

[0056] When one or more sets of tools on a multi-machine tool production line are damaged, the corresponding distributed simple tool magazine 2 will immediately replace the damaged set of tools. At the same time, the distributed simple tool magazine 2 will send the replacement tool model to the closed main tool magazine 1. The closed main tool magazine 1 will take out the corresponding tool and, together with the splicing conveyor mechanism 3, replenish the corresponding tool, ensuring the timeliness of the next tool replacement. Moreover, the tool replacement process is simple and quick, improving the efficiency and convenience of tool replacement in the central tool magazine.

[0057] By energizing several sets of electromagnets 112 to generate magnetism, and then placing several sets of mounting plates 1101 sequentially into a set of mounting slots 111, the electromagnets 112 attract several sets of magnetic metal blocks 1104, thereby fixing several sets of tool fixing assemblies 110 into the vacuum tool storage chamber 108. At the same time, after the sealing door 105 is closed, the limiting posts 1103 at both ends of the mounting plates 1101 move through into the corresponding first limiting slots 113 and second limiting slots 114, so that when the central tool magazine is powered off, the tools will not fall due to the demagnetization of the electromagnets 112. When the tool storage function of the central tool magazine malfunctions, the corresponding mounting plates 1101 can be disassembled and repaired without stopping the machine, thus improving the maintenance efficiency of the central tool magazine.

[0058] By fixing several sets of various types of cutting tools onto several sets of cutting tool fixing assemblies 110, which are distributed in several sets of mounting slots 111 in a circular array, once all the cutting tools are completely fixed, the first electric push rod 103 and the connecting device 104 are controlled to drive the sealing door 105 to seal the vacuum tool storage chamber 108. Then, the air in the vacuum tool storage chamber 108 is evacuated, so that the cutting tools are stored in a vacuum state. When retrieving the cutting tools, the cutting tools do not need to be rotated; the cutting tool retrieval assembly 109 retrieves the corresponding cutting tools. This not only improves the tool storage effect of the central tool magazine but also avoids greater losses caused by accidental contact when the cutting tools rotate, thus improving the safety of the central tool magazine.

[0059] By sequentially connecting and fixing a corresponding number of guide rails 301, several sets of first slide grooves 303 are kept in a connected state. Then, the moving seat 305 is transferred from a set of guide rails 301 at the edge to the inside of the guide rails 301. Limiting devices are then installed on the guide rails 301 at both ends to prevent the moving seat 305 from derailing. In use, the moving seat 305 is controlled to drive the multi-axis robotic arm 306 and the transfer fixture 307 to transport the tool. This allows the central tool magazine to not only autonomously adjust the transport stroke according to the span of the multi-machine production line, but also improves the convenience of installation.

[0060] Based on the aforementioned rapidly positioning array-distributed central tool magazine, this invention also proposes a control method for the rapidly positioning array-distributed central tool magazine. For example, the control method includes:

[0061] The cutting tools of one or more groups of machine tools on a multi-machine tool production line are damaged;

[0062] The corresponding distributed simple tool magazine senses and immediately replaces the damaged tool;

[0063] The corresponding distributed simplified tool magazine will send the replacement tool model to the closed main tool magazine;

[0064] The tool-retrieving mechanism is controlled to transfer the corresponding tool into the tool transfer assembly;
