[0003] Traditional conical tool magazines typically connect the tool magazine frame to the output shaft of the reducer via a flange connection. Due to the overall weight of the tool magazine frame, multiple workers are required to cooperate in the installation process, and the tool magazine frame needs to be continuously lifted and installed. Since the holes also need to be aligned during the installation process, it is difficult to operate during the lifting process. This method is not only time-consuming and labor-intensive to install, but also prone to the tool magazine frame falling off. Utility Model Content
[0004] The purpose of this invention is to provide a quick-drive device for a hat-shaped tool magazine in CNC machine tools. By setting up a support mechanism, specifically by inserting the tool magazine frame into a vertical rod, when the top of the tool magazine frame contacts the flange, the locking block moves to the bottom of the tool magazine frame and is then spring-loaded back to its original position. At this point, the operator can release the tool magazine frame without continuous support, as the locking block will support it. The operator can also rotate the tool magazine frame to adjust the mounting hole position. This method is simpler, more convenient, and more efficient during installation, solving the problem that tool magazine frame installation requires multiple operators and continuous lifting, which is not only time-consuming and labor-intensive but also prone to causing the tool magazine frame to fall.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present utility model.
[0028] Please see Figures 1-5 As shown, this utility model is a quick drive device for a hat-shaped tool magazine in CNC machine tools, including a base 1, a movable seat 11 arranged in front of the base 1, a cylinder 12 mounted on the front of the base 1, a servo motor 13 fixedly connected to the front of the movable seat 11 via a bracket, a reducer 14 arranged below the servo motor 13, and the reducer 14 fixedly connected to the movable seat 11, and also including:
[0029] Tool magazine holder 2, which is positioned directly below the movable base 11; and
[0030] Support mechanism 3 is located at the bottom of reducer 14. Support mechanism 3 includes vertical rod 31, with several limiting grooves 32 at the bottom of vertical rod 31. A locking block 321 is slidably connected inside the limiting groove 32. A spring 322 is fixedly connected to the inner side of the locking block 321. The side of the spring 322 away from the locking block 321 is fixedly connected to the inner wall of the limiting groove 32. When the tool magazine 2 is inserted into the vertical rod 31, the locking block 321 will move to the bottom of the tool magazine 2 and be reset by the elasticity of the spring 322. At this time, the operator can release the tool magazine 2 without continuous support. The locking block 321 will support the tool magazine 2, and the operator can push the tool magazine 2 to rotate and adjust the mounting hole position. This method is simpler, more convenient and more efficient in the installation process.
[0031] The tool magazine holder 2 has a center hole at its center, which is inserted into the vertical rod 31. The inner diameter of the center hole is slightly larger than the diameter of the vertical rod 31.
[0032] The base 1 has two slide rails fixedly connected to its front side, and the movable seat 11 has two sliders mounted on its back side. The sliders slide on the slide rails. The output end of the cylinder 12 is connected to the movable seat 11 via a flange. The reducer 14 has a flange 141 at its bottom and an output shaft 142 at its bottom. The reducer 14 has a connecting shaft at its top, which is fixedly connected to the output end of the servo motor 13 via a coupling. The bottom of the output shaft 142 is connected to the flange 141. A hole is opened on the side of the flange 141, and a long bolt 143 is installed in the hole on the side of the flange 141. The cylinder 12 is used to drive the movable seat 11 to slide on the slide rails of the base 1, thereby moving the tool magazine 2 closer to or away from the tool. The drive of the cylinder 12 can make the movement speed faster. When the servo motor 13 starts, it drives the output shaft 142 to rotate via the coupling. The output shaft 142 then drives the tool magazine 2 to rotate via the flange 141, thereby quickly switching or storing the tool.
[0033] A square plug 33 is fixedly connected to the top of the vertical rod 31. A square groove matching the shape of the square plug 33 is opened at the bottom of the flange 141. Threaded holes 331 are opened on the left and right sides of the square plug 33. The long bolt 143 is threadedly connected to the threaded holes 331.
[0034] The tool magazine holder 2 and the flange 141 are connected by bolts. The tool magazine holder 2 is equipped with several tool holders 21 arranged in a circular array. The tool holders 21 have slots inside, and positioning blocks 22 are installed in the slots. The bottom of the positioning blocks 22 is fixedly connected to the top of the tool magazine holder 2. The tool holders 21 are connected to the tool magazine holder 2 by bolts. The tool holders 21 are positioned and installed on the tool magazine holder 2 by the positioning blocks 22 and locked in place by bolts. The positioning blocks 22 enable the tool holders 21 to be quickly aligned with the holes during installation.
[0035] The top of the card block 321 is flat, the bottom of the card block 321 is inclined, and the top and bottom of the inner side of the card block 321 are both raised, which are used to limit the card block 321.
[0036] A push ring 4 is located at the center of the bottom of the tool magazine 2. Several limiting rods 41 are slidably connected inside the push ring 4. The top of the limiting rods 41 is fixedly connected to the bottom of the tool magazine 2. The inner diameter of the push ring 4 is slightly larger than the diameter of the vertical rod 31. When the tool magazine 2 needs to be disassembled for maintenance, the bolts on the tool magazine 2 and the flange 141 are removed to release the tool magazine 2 from its fixation. Then, the push ring 4 is pushed upward, and the push ring 4 will simultaneously push multiple locking blocks 321 into the limiting grooves 32. Then, the tool magazine 2 is pulled downward for quick disassembly. This method facilitates subsequent maintenance and is simpler and more convenient during disassembly, without requiring too many complicated operations.
[0037] One specific application of this embodiment is:
[0038] In use, the base 1 is installed on the machine tool. When the tool magazine holder 2 needs to be installed, first insert the vertical rod 31 into the bottom of the flange 141 through the square insert 33 at the top, then insert the long bolt 143 into the flange 141 and thread it into the threaded hole 331 on the square insert 33, thereby fixing the vertical rod 31 to the flange 141. Then, lift the tool magazine holder 2 and insert the center of the tool magazine holder 2 into the vertical rod 31. Since the bottom of the locking block 321 is set with an inclined surface, when the tool magazine holder 2 contacts the locking block 321, it will push the locking block 321 into the limiting groove 32. At this time, the spring 322 is compressed, which allows the tool magazine holder 2 to be smoothly inserted into the vertical rod 31. After the top of the tool magazine holder 2 contacts the flange 141, the locking block 321 will move to the bottom of the tool magazine holder 2 and be reset by the elasticity of the spring 322. At this time, the operator can release the tool magazine holder 2 without continuous support. Since the top of the locking block 321 is set with a flat surface, The locking block 321 supports the tool magazine holder 2. At this time, the operator can push the tool magazine holder 2 to rotate, so that the hole on the top of the tool magazine holder 2 is aligned with the hole on the flange 141. Then, the tool magazine holder 2 and the flange 141 are connected and fixed with bolts, and the installation of the tool magazine holder 2 can be completed quickly. When the tool magazine holder 2 needs to be disassembled for maintenance, the bolts on the tool magazine holder 2 and the flange 141 are removed to release the fixation of the tool magazine holder 2. Then, the push ring 4 is pushed upward, and the push ring 4 will push the locking block 321 into the limiting groove 32. Then, the tool magazine holder 2 is pulled downward to disassemble quickly. This method facilitates subsequent maintenance. When the spring 322 is not strong enough, the long bolt 143 is removed to release the fixation of the vertical rod 31. Then, the vertical rod 31 is pulled to disassemble and can be replaced. The tool placement rack 21 is positioned and installed on the tool magazine holder 2 by the positioning block 22 and locked with bolts. The positioning block 22 enables the tool placement rack 21 to quickly align the holes when it is installed.
[0039] When the tool magazine holder 2 is installed and in use, the cylinder 12 drives the moving seat 11 to slide on the slide rail of the base 1, thereby moving the tool magazine holder 2 closer to or away from the tool. The drive of the cylinder 12 can make the movement speed faster. Then the servo motor 13 starts and drives the output shaft 142 to rotate through the coupling. The output shaft 142 drives the tool magazine holder 2 to rotate through the flange 141, thereby quickly switching or storing the tool.
