Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts shall fall within the scope of protection of the present invention.

[0044] The embodiment of the present invention provides a fast positioning array distributed central tool magazine, including a closed main tool magazine 1, a spliced ​​conveying mechanism 3 and a plurality of distributed simple tool magazines 2 distributed in a rectangular array. For example, Figure 1 As shown, the splicing conveying mechanism 3 is located at the output end of the closed main tool magazine 1, and several groups of the distributed simple tool magazines 2 are symmetrically arranged on both sides of the splicing conveying mechanism 3.

[0045] During installation, the number of distributed simple tool magazines 2 and the length of the spliced ​​conveying mechanism 3 are adjusted according to the number and span of machine tools in the multi-machine tool assembly line. The distributed simple tool magazine 2 only has a simple tool changing function and stores a small number of tools required for the corresponding machine tools. When the tools of one or more groups of machine tools are damaged, the corresponding distributed simple tool magazine 2 will replace the damaged one or more groups of tools. At the same time, the distributed simple tool magazine 2 will send the replaced tool model to the closed main tool magazine 1. The closed main tool magazine 1 will take out the corresponding tool and cooperate with the spliced ​​conveying mechanism 3 to replenish the corresponding tool, ensuring the timeliness of the next tool replacement and improving the efficiency and convenience of the tool change in the central tool magazine.

[0046] For example, Figure 2 、 Figure 3 and Figure 4 As shown, the closed main tool magazine 1 includes a first shell 101; a support base 102 is provided at the bottom of the first shell 101; a vacuum tool storage chamber 108 is provided in the first shell 101; the inner wall of the vacuum tool storage chamber 108 away from the splicing conveying mechanism 3 is an open structure; two groups of first electric push rods 103 are provided on the top of the first shell 101; the output ends of the two groups of first electric push rods 103 are transmission-connected with a connecting device 104; a closed door 105 is provided on the connecting device 104; the closed door 105 movably closes the vacuum tool storage chamber 108; a plurality of groups of mounting grooves 111 are distributed in a circular array on the inner wall of the vacuum tool storage chamber 108; each group of the mounting grooves 111 is provided with a group of tool fixing components 1 10; A knife taking assembly 109 is provided in the vacuum knife storage chamber 108; a first motor 107 is provided on a side wall of the first shell 101 close to the splicing conveying mechanism 3; the output end of the first motor 107 is transmission-connected with the knife taking assembly 109; a tool transfer assembly 106 is provided on a side wall of the first shell 101 close to the splicing conveying mechanism 3; a plurality of groups of electromagnets 112 are evenly spaced on the inner wall of the mounting groove 111 away from the knife taking assembly 109; a plurality of groups of first limiting grooves 113 are distributed in a circular array on the inner wall of the side of the closed door 105 close to the vacuum knife storage chamber 108; a plurality of groups of second limiting grooves 114 are distributed in a circular array on the inner wall of the side of the vacuum knife storage chamber 108 close to the first motor 107.

[0047] Several groups of tools of various models are fixed on several groups of tool fixing assemblies 110, and several groups of tool fixing assemblies 110 are distributed in several groups of mounting grooves 111 in a circular array. When all the tools are completely fixed, the first electric push rod 103 and the connecting device 104 are controlled to drive the closing door 105 to close the vacuum tool storage chamber 108, and then the air in the vacuum tool storage chamber 108 is extracted, so that several groups of tools are stored in a vacuum state. When taking out the tools, several groups of tools do not need to be rotated, and the tool taking assembly 109 takes out the corresponding tools, which not only improves the tool storage effect of the central tool magazine, but also avoids greater losses caused by accidental rotation of the tools, thereby improving the safety of the central tool magazine.

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

[0049] During the installation work, first measure the span of the multi-machine tool assembly line, then select the corresponding number of guide rails 301 and connect and fix them in sequence, so that several groups of first slide grooves 303 remain connected, and then transfer the movable seat 305 from a group of guide rails 301 at the edge to the inside of the guide rails 301, and then install limit devices on the guide rails 301 at both ends to prevent the movable seat 305 from derailing. When in use, control the second motor 310 to drive the gear 311 to rotate, and under the meshing connection relationship between the gear 311 and the rack 309, the movable seat 305 drives the multi-axis robot arm 306 and the transfer fixture 307 to transport the tool, so that the central tool magazine can not only autonomously adjust the conveying stroke according to the span of the multi-machine tool assembly line, but also improve the convenience of the installation work.

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

[0051] When transferring the tool, first control the first sealing plate 1062 to open, then control the tool removal assembly 109 to transfer the corresponding tool between the two sets of tool body fixing plates 1067, then control the two sets of second electric push rods 1066 to drive the two sets of tool body fixing plates 1067 to clamp the tool, then control the tool removal assembly 109 to release the clamping of the tool and reset it, then control the first sealing plate 1062 to close, then control the second sealing plate 1063 to open, and then control the electric slide 1064 to drive the mounting ring 1065 to transfer the tool to the outside of the first shell 101, and the splicing conveying mechanism 3 transfers the tool to the corresponding distributed simple tool magazine 2. During the entire tool transfer process, the vacuum tool storage chamber 108 always remains closed, which prevents external impurities from entering and corroding the tool, thereby increasing the service life of the tool.

[0052] For example, Figure 8 As shown, the knife-removing assembly 109 includes a guide column 1091; a second slide groove 1092 is provided on the outer wall of the guide column 1091; a screw rod 1093 is provided in the second slide groove 1092; the output end of the first motor 107 is transmission-connected to the screw rod 1093; a guide ring 1094 is movably sleeved on the outer wall of the guide column 1091; a slider 1095 is provided on the inner wall of the guide ring 1094; the slider 1095 is slidingly connected in the second slide groove 1092 and is threadedly connected to the screw rod 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; and a knife-removing clamp 1098 is transmission-connected to the output end of the third electric push rod 1097.

[0053] When removing the tool, the closed main tool magazine 1 receives a signal from the corresponding distributed simple tool magazine 2, and first controls the first motor 107 to drive the screw rod 1093 to rotate. Under the threaded connection relationship between the screw rod 1093 and the slider 1095, the slider 1095 drives the guide ring 1094 to move to the corresponding horizontal position, and then controls the rotating ring 1096 to drive the third electric push rod 1097 to rotate, so that the tool removal fixture 1098 is aligned with the tool to be removed, and then controls the third electric push rod 1097 to drive the tool removal fixture 1098 to remove the tool, and then controls the tool to be transferred to the tool transfer assembly 106. During the whole process, several groups of tools do not need to be rotated, avoiding greater losses caused by accidental tool rotation.

[0054] For example, 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 grooves 111; a plurality of groups of tool sleeves 1102 are provided at equal intervals on a side wall of the mounting plate 1101 close to the tool removal assembly 109; two groups of limiting columns 1103 are symmetrically provided on both side walls of the mounting plate 1101; the two groups of limiting columns 1103 are movable through a corresponding set of first limiting grooves 113 and second limiting grooves 114 respectively; a plurality of groups of magnetic metal blocks 1104 are provided at equal intervals on a side wall of the mounting plate 1101 away from the tool sleeve 1102; each group of the magnetic metal blocks 1104 is movably fitted with a corresponding set of electromagnets 112.

[0055] A plurality of mounting grooves 111 are distributed in a circular array on the inner wall of the first shell 101, and the cross-section of the mounting grooves 111 is rectangular. Then, the plurality of electromagnets 112 are energized so that the plurality of electromagnets 112 generate magnetism. Then, the plurality of mounting plates 1101 are placed in a group of mounting grooves 111 in sequence so that the plurality of electromagnets 112 adsorb the plurality of magnetic metal blocks 1104, thereby fixing the plurality of tool fixing assemblies 110 in the vacuum tool storage chamber 108. At the same time, after the closed door 105 is closed, the limiting columns 1103 at both ends of the plurality of mounting plates 1101 are movable and penetrate into the corresponding group of first limiting grooves 113 and second limiting grooves 114 respectively, so that when the central tool magazine is powered off, the plurality of tools will not fall due to the demagnetization of the plurality of electromagnets 112. When the tool storage function of the central tool magazine fails, the corresponding mounting plates 1101 can be disassembled and repaired without stopping the machine for maintenance, thereby improving the maintenance efficiency of the central tool magazine.

[0056] When one or more groups of tools in a multi-machine assembly line are damaged, the corresponding distributed simple tool magazine 2 will immediately replace the damaged one or more groups of tools. At the same time, the distributed simple tool magazine 2 will send the replaced tool model to the closed main tool magazine 1. The closed main tool magazine 1 will take out the corresponding tools and cooperate with the splicing conveying mechanism 3 to replenish the corresponding tools, ensuring the timeliness of the next tool replacement. The tool changing process is simple and fast, which improves the efficiency and convenience of the tool changing in the central tool magazine.

[0057] By energizing several groups of electromagnets 112 to generate magnetism, and then placing several groups of mounting plates 1101 in a group of mounting grooves 111 in sequence, several groups of electromagnets 112 absorb several groups of magnetic metal blocks 1104, thereby fixing several groups of tool fixing assemblies 110 in the vacuum tool storage chamber 108. At the same time, after the closed door 105 is closed, the limiting columns 1103 at both ends of the several groups of mounting plates 1101 are movable and penetrate into the corresponding group of first limiting grooves 113 and second limiting grooves 114, so that when the central tool magazine is powered off, the several groups of tools will not fall due to the demagnetization of the several groups of electromagnets 112. When the tool storage function of the central tool magazine fails, the corresponding mounting plates 1101 can be disassembled and repaired without stopping the machine for maintenance, thereby improving the maintenance efficiency of the central tool magazine.

[0058] By fixing several groups of various types of tools on several groups of tool fixing assemblies 110, and several groups of tool fixing assemblies 110 are distributed in several groups of mounting grooves 111 in a circular array, when all the tools are completely fixed, the first electric push rod 103 and the connecting device 104 are controlled to drive the closing door 105 to close the vacuum tool storage chamber 108, and then the air in the vacuum tool storage chamber 108 is extracted, so that several groups of tools are stored in a vacuum state. When taking out the tools, several groups of tools do not need to be rotated, and the tool taking assembly 109 takes out the corresponding tools, which not only improves the tool storage effect of the central tool magazine, but also avoids greater losses caused by accidental rotation of the tools, thereby improving the safety of the central tool magazine.

[0059] By connecting and fixing the corresponding number of guide rails 301 in sequence, several groups of first slide grooves 303 are kept in a connected state, and then the movable seat 305 is transferred from a group of guide rails 301 at the edge to the inside of the guide rails 301, and then the guide rails 301 at both ends are equipped with limit devices to prevent the movable seat 305 from derailing. When in use, the movable seat 305 is controlled to drive the multi-axis robot arm 306 and the transfer fixture 307 to transport the tool, so that the central tool magazine can not only autonomously adjust the transportation stroke according to the span of the multi-machine tool assembly line, but also improve the convenience of installation work.
