Description

Technical Field

[0001] This invention relates to the field of machine tool magazine technology, and in particular to a tool magazine linkage mechanism. Background Technology

[0002] A machine tool tool magazine is a device that provides the necessary tool storage and changing capabilities for automated machining processes. Its automatic tool changing mechanism and ability to store multiple tools have transformed traditional, human-intensive production methods. Through computer program control, various machining operations such as milling, drilling, boring, and tapping can be completed, significantly shortening machining time and reducing production costs.

[0003] Chinese patent CN207757304U discloses a tool magazine linkage mechanism, including a worktable, a tool magazine slide, and a power mechanism for controlling the movement of the worktable. The worktable has a tool holder connecting seat at its rear, and the bottom of the tool magazine slide has a tool magazine lever seat and a tool magazine lever. The lever's rod is hinged to the tool magazine lever seat via a horizontally arranged hinge shaft. The tool magazine slide also has a drive mechanism for controlling the rotation of the tool magazine lever. The rear end of the tool magazine lever is hinged to the drive mechanism. Under the drive of the drive mechanism, the front end of the tool magazine lever connects or separates from the tool holder connecting seat. This tool magazine slide is driven by the worktable, ensuring the transmission accuracy of the tool magazine slide and eliminating the need for an additional transmission mechanism to drive its movement, thus reducing the cost of the tool magazine. However, during tool changing, the surface of the replaced tool will be covered with a large amount of debris and impurities. Existing technologies generally use air nozzles to blow air onto the tool, but the tool's irregular shape means that some debris and impurities will remain in dead corners and cannot be blown away, resulting in incomplete tool cleaning.

[0004] In view of this, the present invention proposes a tool magazine linkage mechanism to solve the problems existing in the prior art. Summary of the Invention

[0005] The purpose of this invention is to address the shortcomings of existing technologies by proposing a tool magazine linkage mechanism.

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

[0024] The technical solution of the present invention will be further described in detail below with reference to specific embodiments.

[0025] Reference Figure 1 , Figure 4 and Figure 5A tool magazine linkage mechanism includes a tool changing mechanism 6 with a horizontal plate 1. One end of the horizontal plate 1 has a tool-retrieving end 3, and the other end has a tool changing end 7. A lifting mechanism is mounted on the horizontal plate 1, and a cleaning cylinder 17 is mounted on the lifting mechanism. A fixed column 21 is installed inside the cleaning cylinder 17, and a drive mechanism for rotating the fixed column 21 is located at the bottom of the cleaning cylinder 17. The cleaning cylinder 17 is directly below the tool-retrieving end 3. A sliding groove 27 is provided on the fixed column 21, and a pair of fixed plates 22 are fixedly connected to both ends of the fixed column 21. A rotating shaft 29 is rotatably connected between each pair of fixed plates 22, and a swing column 23 is fixedly connected to the top outer wall of each rotating shaft 29. A cleaning ball 20 is provided at the top of each swing column 23. A swing mechanism is provided in the sliding groove 27, and the swing mechanism allows the two swing columns 23 to swing towards the center of the fixed column 21. When changing tools, the tool changing mechanism 6 can remove the used tool through the tool-retrieving end 3. Simultaneously, the tool to be used is removed from the tool magazine via the tool changing end 7. Then, the tool changing mechanism 6 rotates the horizontal plate 1 180 degrees to complete the tool changing operation. During this process, after the tool used by the tool taking end 3 is removed, the lifting mechanism is activated, causing the cleaning cylinder 17 to move upward, so that the lower part of the tool from the tool taking end 3 enters the cleaning cylinder 17. At the same time, the lifting mechanism moves the cleaning cylinder 17 upward, and the rotating mechanism is activated. The rotating mechanism can rotate the fixed column 21. At this time, the swing mechanism operates, so that the two swing columns 23 can swing with the cleaning balls 20 at the top, so that they move closer to each other. During this process, the two cleaning balls 20 will contact the lower end of the tool and rotate upward. By controlling the rotation speed of the fixed column 21 through the rotating mechanism, the distance between the two cleaning balls 20 can be controlled, so that the cleaning balls 20 are in close contact with the irregular shape of the tool, completing the cleaning work of the tool and avoiding cleaning dead corners.

[0026] Reference Figure 1 As a further embodiment of the present invention, the lifting mechanism includes an electric push rod 4, which is mounted on the horizontal plate 1. The telescopic end of the electric push rod 4 is fixedly connected to the mounting plate 2. The cleaning cylinder 17 is fixedly connected to the mounting plate 2 by bolts. The electric push rod 4 can move the mounting plate 2 up and down. The cleaning cylinder 17 can be disassembled by bolts to clean the accumulated garbage and debris in the cleaning cylinder 17.

[0027] Reference Figure 3 and Figure 4As a further embodiment of the present invention, the driving mechanism includes a rotating shaft 16, which is rotatably connected to the bottom of the cleaning cylinder 17, and the top end of the rotating shaft 16 is fixedly connected to the middle of the fixed column 21. A pulley 25 is fixedly connected to the bottom end of the rotating shaft 16, and a rotary motor 19 is provided on one side of the pulley 25. A pulley 13 is fixedly connected to the output shaft end of the rotary motor 19, and a transmission belt 14 is sleeved on the outer wall of the pulley 13 and the pulley 25. The rotary motor 19 rotates the fixed column 21 at the top end of the rotating shaft 16 through the cooperation of the pulley 13, the transmission belt 14 and the pulley 25.

[0028] Reference Figure 5 As a further embodiment of the present invention, the swing mechanism includes two counterweights 25, which are slidably connected inside the sliding groove 27, and a connecting spring 26 is fixedly connected between the two counterweights 25. Inclined rocker plates 24 are provided between the counterweights 25 and the rotating shaft 29. When the fixed column 21 rotates, under the action of centrifugal force, the two counterweights 25 will stretch the connecting spring 26 and move away from each other.

[0029] Reference Figure 5 As a further embodiment of the present invention, the upper end of the rocker 24 is fixedly connected to the corresponding rotating shaft 29, and the lower end of the rocker 24 is in contact with the outer wall of the corresponding counterweight 25. A connecting spring 28 is provided between the rocker 24 and the inner wall of the sliding groove 27. Since the lower end of the rocker 24 is in contact with the outer wall of the corresponding counterweight 25, and the upper end of the rocker 24 is fixedly connected to the corresponding rotating shaft 29, when the counterweight 25 moves, the rocker 24 causes the swing column 23 to overcome the centrifugal force of outward swing and swing towards the middle of the fixed column 21.

[0030] Working principle: When changing tools, the tool changing mechanism 6 removes the used tool through the tool-retrieving end 3, and simultaneously retrieves the tool to be used from the tool magazine through the tool changing end 7. Then, the tool changing mechanism 6 rotates the horizontal plate 1 180 degrees to complete the tool changing operation. During this process, after the used tool is removed from the tool-retrieving end 3, the electric push rod 4 is activated, which moves the mounting plate 2 upward, thereby moving the cleaning cylinder 17 upward, so that the lower part of the tool from the tool-retrieving end 3 enters the cleaning cylinder 17. At the same time as the cleaning cylinder 17 moves upward, the rotary motor 19 is activated. The rotating motor 19, through the cooperation of pulley 13, transmission belt 14, and pulley 15, causes the fixed column 21 at the top of the rotating shaft 16 to rotate. When the fixed column 21 rotates, the counterweight 25 moves outward in the sliding groove 27 under the action of centrifugal force. At this time, the connecting spring 26 between the two counterweights 25 is stretched, and because the lower end of the rocker arm 24 contacts the outer wall of the corresponding counterweight 25, and the upper end of the rocker arm 24 is fixedly connected to the corresponding rotating shaft 29, the counterweight 25 pushes the lower end of the rocker arm 24 to swing outward when it moves outward. That is, the rocker arm 24 acts as... The "angle rocker arm" converts the radial displacement of the counterweight 25 into an angular torque about the second rotating shaft 29. The rocker arm 24, the second rotating shaft 29, and the swing column 23 are all made of lightweight materials, which is existing technology. Meanwhile, the cleaning ball 20, because it needs to clean the lower end of the tool, needs to be designed to be small, resulting in a lighter weight. Furthermore, the weight of the counterweight 25 is much greater than the weight of the rocker arm 24, the second rotating shaft 29, the swing column 23, and the cleaning ball 20. Therefore, when the fixed column 21 rotates, the centrifugal force on the rocker arm 24, the swing column 23, and the cleaning ball 20 will be much less than that on the counterweight 25. The weight 25 exerts an angular torque on the rotating shaft 29 via the rocker 24, causing the rotating shaft 29 to rotate and drive the upper ends of the two swing columns 23 to move closer together. This causes the two swing columns 23 to swing with the cleaning balls 20 at their tops, bringing them closer together. During this process, the two cleaning balls 20 will contact the lower end of the tool and rotate upwards. By controlling the rotation speed of the fixed column 21 through the rotation mechanism, the distance between the two cleaning balls 20 can be controlled, ensuring that the cleaning balls 20 are in close contact with the irregular shape of the tool, thus completing the cleaning work on the tool and avoiding cleaning dead corners.

[0031] Reference Figure 6As a further embodiment of the present invention, the outer wall of the cleaning cylinder 17 is provided with a receiving cavity 33, and an electromagnet 30 is provided at the bottom of the receiving cavity 33. A protective cylinder 18 is slidably connected to the top of the receiving cavity 33, and a magnetic disk 32 is fixedly connected to the bottom of the protective cylinder 18. Multiple connecting springs 31 are fixedly connected between the magnetic disk 32 and the electromagnet 30. Before the tool is removed from the machine via the tool-removing end 3 on the horizontal plate 1, the tool-changing mechanism 6 inputs current to the electromagnet 30. After the electromagnet 30 is energized, the magnetic force generated attracts the magnetic disk 32, causing the magnetic disk 32 to compress the connecting springs 31 and move downward, thereby causing the protective cylinder 18 to retract into the receiving cavity 33, thus not obstructing the tool removal operation. After the tool removal is completed, the electromagnet 30 is de-energized, and the protective cylinder 18 extends out of the receiving cavity 33 again, covering the lower end of the tool on the tool-removing end 3, thereby preventing the waste debris from being splashed around during cleaning.

[0032] Reference Figure 1 and Figure 2 As a further embodiment of the present invention, a vacuum cleaner 5 is provided on one side of the outer wall of the blade changing mechanism 6, and an electric push rod 3 11 is fixedly connected to the outer wall of the vacuum cleaner 5. The telescopic end of the electric push rod 3 11 is fixedly connected to a horizontally placed electric push rod 2 9, and the telescopic end of the electric push rod 2 9 is fixedly connected to a suction pipe 10. When it is necessary to clean the two cleaning balls 20 in the cleaning cylinder 17, the blade changing mechanism 6 moves the blade-taking end 3 of the horizontal plate 1 to directly below the vacuum cleaner 5, and the drive mechanism is activated to make the fixed column 21 parallel to the suction pipe 10. Then the electric push rod 3 11 and the electric push rod 2 9 are activated, and at the same time the electromagnet 30 is energized to make the protective cylinder 18 retract into the receiving cavity 33.

[0033] Reference Figure 1 and Figure 2 As a further embodiment of the present invention, the suction pipe 10 is connected to the input end of the vacuum cleaner 5 by a telescopic tube 12, and two suction sleeves 8 are symmetrically connected to the bottom of the suction pipe 10. The cleaning ball 20 can enter the corresponding suction sleeve 8. The cooperation of the electric push rod 3 11 and the electric push rod 2 9 can allow the two suction sleeves 8 to be inserted into the cleaning cylinder 17, and at the same time allow the cleaning ball 20 to enter the corresponding suction sleeve 8. Then the vacuum cleaner 5 is started, and through the telescopic tube 12 and the suction pipe 10, a huge suction force is generated in the two suction sleeves 8, thereby cleaning the cleaning ball 20, removing the waste debris and other garbage attached to it, keeping the cleaning ball 20 clean, so that the cleaning blade can clean it clean next time.

[0034] Working principle: Before the tool is removed from the horizontal plate 1 via the tool-retrieving end 3, the tool-changing mechanism 6 inputs current to the electromagnet 30. The electromagnet 30, when energized, generates magnetic force that attracts the magnetic disk 32, causing the magnetic disk 32 to compress the connecting spring 31 and move downwards. This retracts the protective cylinder 18 into the receiving cavity 33, thus preventing obstruction of the tool-retrieving operation. After tool removal, the electromagnet 30 is de-energized, allowing the protective cylinder 18 to extend out of the receiving cavity 33 again, securing the lower end of the tool on the tool-retrieving end 3, preventing debris from scattering during cleaning. When cleaning the two cleaning balls 20 in the cleaning cylinder 17, the tool-changing mechanism 6 moves the tool-retrieving end 3 of the horizontal plate 1 to... Directly below the vacuum cleaner 5, the drive mechanism is activated to align the fixed post 21 parallel to the suction pipe 10. Then, the electric push rod 31 and electric push rod 29 are activated, simultaneously energizing the electromagnet 30 to retract the protective cylinder 18 into the receiving cavity 33. The cooperation of the electric push rod 31 and electric push rod 29 allows the two suction sleeves 8 to be inserted into the cleaning cylinder 17, and the cleaning ball 20 to enter the corresponding suction sleeve 8. Then, the vacuum cleaner 5 is activated, and through the telescopic tube 12 and the suction pipe 10, a huge suction force is generated in the two suction sleeves 8 to clean the cleaning ball 20, removing the debris and other garbage attached to it, keeping the cleaning ball 20 clean, so that the cleaning blade can clean it thoroughly next time.
