A heavy-duty vertical lathe tool magazine

Abstract

This utility model relates to the field of tool magazine technology, and more particularly to a heavy-duty vertical lathe tool magazine, including a rotating shaft, a tool disc, and a driving component. The tool disc is concentrically mounted on the rotating shaft, and the driving component drives the tool disc to rotate. The tool disc includes a disc-shaped tool holder with multiple grooves for mounting tools. Support seats are provided on both sides of the grooves, and a buffer structure is provided between the support seats and the tool holder. By providing a buffer structure between the tool holder and the support seats, during the process of returning a heavy-duty tool to the tool magazine, the tool first contacts the buffer structure. The buffer structure undergoes elastic deformation or movement after being subjected to force, thereby effectively absorbing impact energy, delaying the rigid contact between the tool and the support seats, and significantly reducing the impact force generated at the moment of returning to the magazine. This reduces the wear of structural components, improves the stability and accuracy of tool positioning, avoids the problem of unstable tool changing caused by impact, thereby extending the service life of the tool magazine and improving the overall operational reliability of the machine.

Description

Technical Field

[0001] This utility model relates to the field of tool magazine technology, and in particular to a heavy-duty vertical lathe tool magazine. Background Technology

[0002] As a key module of its automatic tool changer system, the heavy-duty vertical lathe tool magazine needs to carry ultra-heavy cutting tools weighing hundreds of kilograms and achieve high-precision and high-reliability tool exchange. The tool magazine can accommodate various types of heavy tools and realize the rapid replacement of tools between the spindle and the tool magazine through a robot or automatic tool changer, thereby realizing the continuous machining of complex workpieces.

[0003] However, due to the large mass of heavy-duty cutting tools, during tool changing, especially at the moment the tool returns to the tool magazine, the direct contact between the tool and the support can easily generate a large impact force. This impact can not only aggravate the wear of structural components, but may also lead to inaccurate tool positioning and unstable tool changing process, thereby affecting the stability of machine tool operation and the service life of the tool magazine system.

[0004] The information disclosed in this background section is intended only to enhance the understanding of the general background of this utility model and should not be construed as an admission or in any way implying that the information constitutes prior art known to those skilled in the art.

[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

Therefore, they should not be construed as limitations on this utility model.

[0033] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to fixed connections, detachable connections, or integral connections; they can refer to mechanical connections or electrical connections; they can refer to direct connections or indirect connections through an intermediate medium; and they can refer to the internal communication between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0034] like Figures 1 to 5 As shown: A heavy-duty vertical lathe tool magazine includes: a rotating shaft 1, a tool head 2, and a driving component;

[0035] The cutter head 2 is concentrically mounted on the rotating shaft 1, and the driving component drives the cutter head 2 to rotate.

[0036] The tool holder 2 includes a disc-shaped tool holder 21. The tool holder 21 is provided with multiple grooves 22 for mounting the tool 01. Support seats 23 are provided on both sides of the grooves 22. A buffer structure 24 is provided between the support seats 23 and the tool holder 21 to reduce the impact force when the tool 01 returns to the tool magazine.

[0037] By setting a buffer structure 24 between the tool holder 21 and the support base 23, during the process of returning the heavy-duty tool 01 to the tool magazine, the tool 01 first contacts the buffer structure 24. After being subjected to force, the buffer structure 24 undergoes elastic deformation or movement, thereby effectively absorbing the impact energy, delaying the rigid contact between the tool 01 and the support base 23, and significantly reducing the impact force generated at the moment of returning to the magazine.

[0038] This structure can reduce the wear of structural components, improve the stability and accuracy of tool positioning, avoid the problem of unstable tool changing caused by impact, thereby extending the service life of the tool magazine and improving the overall operational reliability of the machine.

[0039] Compared with the prior art, the buffer structure 24 of the present invention introduces a flexible contact process at the key position of the tool 01 returning to the magazine, which effectively solves the problem of impact when the heavy-duty tool 01 returns to the magazine due to its large inertia. It is especially suitable for vertical lathe equipment that frequently changes tools or carries ultra-heavy tools 01.

[0040] As a preferred embodiment of the above, the buffer structure 24 includes a stepped hole 231 vertically disposed inside the support base 23, a buffer push rod 241 disposed inside the stepped hole 231, and a spring 25 disposed at the bottom of the buffer push rod 241.

[0041] The buffer push rod 241 includes a first diameter section 241a and a second diameter section 241b. The first diameter section 241a is smaller than the second diameter section 241b, and the end portion of the diameter section protrudes from the surface of the support base 23. Specifically, by setting a stepped hole 231 inside the support base 23 and setting a buffer push rod 241 with a spring 25 inside the stepped hole 231, a compact and responsive buffer structure 24 is formed. The buffer push rod 241 is set as a stepped structure with a first diameter section 241a and a second diameter section 241b, which allows it to slide axially in the stepped hole 231. The end of the first diameter section 241a protrudes from the surface of the support base 23, so that it first contacts the tool 01 during the tool 01 return process and compresses the spring 25 downward after being subjected to force, thus achieving flexible buffering. This not only effectively reduces the impact force when the tool 01 returns to the magazine, but also has good guiding and resetting performance, thereby further improving the stability and support accuracy of the tool 01 during the return process, reducing structural wear, and extending the service life of the tool magazine.

[0042] In this embodiment, the bottom of the buffer push rod 241 is provided with a first blind hole 214c, and the tool holder 21 is provided with a second blind hole. One end of the spring 25 is located in the first blind hole 214c, and the other end is located in the second blind hole, thereby effectively positioning the spring 25, preventing the spring 25 from axially shifting or dislodging during the compression process, ensuring the stable guidance of the spring 25 during the compression and reset process, and improving the response consistency and durability of the buffer structure 24.

[0043] One specific implementation of the end of the buffer push rod 241 is as follows: the end of the first diameter segment 241a is a plane. Specifically, the plane is easier to process, so that when it contacts the tool 01 during the tool magazine return process, it can form a stable and uniform force-bearing surface, effectively avoiding the problem of local stress concentration caused by point contact or inclined contact, thereby improving the reliability and repeatability of the buffering effect.

[0044] Another specific implementation of the end of the buffer push rod 241 is as follows: the end of the first diameter section 241a is an outwardly convex arc surface. Specifically, the arc surface shape has good self-guiding characteristics and can adapt to the surface of the tool 01 with different shapes or slight angular deviations, ensuring a smoother and more stable contact process.

[0045] The drive components include a servo motor 3, a reducer 4, a drive gear 5, and a driven gear 6. The rotating shaft 1 is mounted on the base, and a tapered roller bearing 7 is provided between the rotating shaft 1 and the tool holder 21. The rotation of the servo motor 3 drives the tool holder 2 to rotate. The reducer 4 performs the first reduction of the servo motor 3, and the drive gear 5 and driven gear 6 perform the second reduction. Specifically, by combining the servo motor 3 with the reducer 4, drive gear 5, and driven gear 6 to form a graded reduction system, multi-stage reduction drive control of the rotating shaft 1 is realized. The reducer 4 achieves the first reduction of the output of the servo motor 3, and the meshing of the drive gear 5 and driven gear 6 achieves the second reduction, thereby effectively reducing the rotation speed of the tool holder 2 and increasing the transmission torque, ensuring the smooth operation and high-precision positioning of the tool magazine during tool changing. In addition, the tapered roller bearing 7 connects the rotating shaft 1 and the tool holder 21, enhancing the overall support rigidity and load-bearing capacity, improving the stability and durability of the tool holder 2 during rotation, and making it suitable for high-intensity working environments that bear ultra-heavy-duty tools 01.

[0046] In this embodiment, a positioning pin 26 is also provided inside the support base 23. The positioning pin 26 protrudes from the surface of the support base 23 and corresponds to the position of the hole on the tool 01. When the tool 01 is returned to the tool magazine, it can achieve fast and accurate positioning and engagement, effectively preventing the tool 01 from shifting axially or radially on the support surface, and improving the installation accuracy and position repeatability of the tool 01.

[0047] As a preferred embodiment of the above embodiment, an outer cover 8 for protecting the cutter head 2 is also included;

[0048] The outer casing 8 includes a side plate 81, a top plate 82, a bottom plate 83, and a support plate 84. The side plate 81, top plate 82, and bottom plate 83 enclose a receiving space, in which the cutter head 2 is located. The support plate 84 is mounted on the tool holder 21 and is used to support the outer casing 8, preventing impurities such as chips, dust, or coolant generated during processing from entering the tool magazine area, thereby reducing the risk of equipment contamination and wear.

[0049] In this embodiment, other parts are all protected by separate protective covers, such as the solenoid valve protective cover and the cylinder 853 protective cover, which are all within the protection scope of this application.

[0050] Among them, the outer casing 8 is equipped with an automatic door 85 at the tool changing position;

[0051] The automatic door 85 includes a first door panel 851, a first guide rail 852, and a cylinder 853. The cylinder 853 drives the first door panel 851 to move along the first guide rail 852, thereby opening or closing the automatic door 85. Specifically, the first door panel 851 is L-shaped, and the first guide rail 852 is located at both ends of the L-shaped first door panel 851. When the extended end of the cylinder 853 extends, the automatic door 85 opens; when the extended end of the cylinder 853 retracts, the automatic door 85 closes, thus realizing the opening and closing control of the automatic door 85. Dynamic opening and closing is achieved during the tool changing process, thereby ensuring the normal operation of the automatic tool changing function while effectively improving the sealing and protection performance of the equipment.

[0052] The automatic door 85 is equipped with a photoelectric sensor switch 9 on the knife holder 21, which can realize real-time detection and signal feedback of whether the automatic door 85 is closed in place.

[0053] In this embodiment, the outer casing 8 is also provided with a manual door 86 for manually installing the tool 01;

[0054] The manual door 86 includes a second door panel 861, a second guide rail 862, and a latch (not shown). The second guide rail 862 is located at both ends of the second door panel 861, and the second door panel 861 slides along the second guide rail 862. The latch is located on one side of the second door panel 861 and is used to lock the second door panel 861. This not only simplifies the manual replacement and inspection process of the tool 01 and improves the human-machine interaction of the equipment, but also ensures the safety and protection of the equipment operation while taking into account the convenience of daily maintenance, which is conducive to improving the overall efficiency of the machine.

The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model.
