[0039] In order to make the person skilled in the art better understand the technical scheme of the present application, the technical scheme in the embodiments of the present application will be described clearly and completely below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, not all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by the person skilled in the art without creative labor should belong to the scope of protection of the present application.

[0040] Reference Figure 1 、 Figure 2 、 Figure 4 The embodiments of the present application provide a machine tool, which mainly comprises a bed body 1 and other auxiliary components. The bed body 1 is the main structure of the machine tool, mainly comprising a base 11, a workbench 12, two columns 13, a crossbeam 14, a machine head 15 and a first driving assembly 16 for driving the movement of the machine head 15. The base 11 is the supporting foundation of the whole machine tool, which is stably installed on the ground. The workbench 12 is arranged on the base 11 and located on one side of the two columns 13, which is used for placing and fixing the workpiece to be processed. The two columns 13 are respectively erected on the two sides of the base 11. The crossbeam 14 spans the top of the two columns 13 and forms a stable frame structure with the columns 13. A guide rail is arranged on the crossbeam 14, which provides a path for the movement of the machine head 15. The machine head 15 is movably arranged on the guide rail through some connection mode (such as a sliding block), so that the machine head 15 can move on the crossbeam 14 to process the workpiece on the workbench 12. The first driving assembly 16 is arranged on the crossbeam 14 and is responsible for providing power for the movement of the machine head 15. The first driving assembly 16 can include motor, reducer, transmission mechanism and other components, through accurate control, the stable and rapid movement of the machine head 15 on the guide rail can be realized.

[0041] In addition to the basic structure described above, the machine tool of the present embodiment further comprises a tool magazine rail 2 and a tool magazine device 3. The tool magazine rail 2 extends along the front-rear direction of the worktable 12 and is arranged at the rear of the base 11. The tool magazine rail 2 provides a path for the movement of the tool magazine device 3. The tool magazine device 3 is movably arranged on the tool magazine rail 2 and is used to store and manage a plurality of tools. The tool magazine device 3 is internally provided with a tool magazine accommodating cavity 31, which is carefully designed in shape and size to accommodate one or more tools. A first tool changing opening 32 is arranged on the top surface of the tool magazine accommodating cavity 31 near the side of the worktable 12. A second tool changing opening 33 is arranged on the side of the tool magazine accommodating cavity 31 facing the worktable 12, and the first tool changing opening 32 and the second tool changing opening 33 are used to provide a space for the tool changing of the machine head 15.

[0042] When the machine head 15 needs to perform a tool changing operation, the tool magazine device 3 moves to a tool changing position along the tool magazine rail 2, and the machine head 15 moves above the first tool changing opening 32. Then, through a certain tool changing mechanism (such as a mechanical arm, a pneumatic gripper, etc.), the machine head 15 can take out the required tool from the tool magazine accommodating cavity 31 or put the used tool back into the tool magazine accommodating cavity 31. The arrangement of the first tool changing opening 32 and the second tool changing opening 33 provides sufficient space for the tool changing operation of the machine head 15, ensuring the smooth progress of the tool changing process.

[0043] By arranging the tool magazine accommodating cavity 31 in the tool magazine device 3, when the machine head 15 is processing, the tool magazine 4 is located in the tool magazine accommodating cavity 31, and the tool magazine device 3 plays a protective role for the tool magazine 4. When the machine head 15 is changing tools, the tool magazine device 3 moves directly below the machine head 15, and the machine head 15 takes tools from the tool magazine 4 through the first tool changing opening 32. The entire tool magazine 4 is only partially exposed through the first tool changing opening 32, and the tool magazine device 3 still plays a protective role for the tool magazine 4. By placing the tool magazine 4 in the tool magazine accommodating cavity 31 and allowing the machine head 15 to change tools through the first tool changing opening 32, the tool magazine 4 is protected by the accommodating cavity during the processing and tool changing processes, effectively protecting the cleanliness of the tools.

[0044] In an embodiment, reference is made to Figure 1 , Figure 4 and Figure 5The first tool changing opening 32 is disposed on the top surface of the tool magazine accommodating cavity 31 near the side of the worktable 12, and is sized to be adapted to the spindle of the machine head 15. This means that when the machine head 15 is moved above the first tool changing opening 32, the spindle can just pass through the first tool changing opening 32 to enter the tool magazine accommodating cavity 31 for tool changing operation. In order to ensure the smooth progress of the tool changing process, a certain interval is maintained between the nearest side of the first tool changing opening 32 and the outer circumference of the spindle. This interval is controlled to be between 1-2 cm, which can not only ensure that the spindle has enough space to move and adjust during tool changing, but also avoid the problem of easy entry of external debris into the tool magazine accommodating cavity 31 due to too large interval.

[0045] In an embodiment, referring to Figure 1 and Figure 4 , the opening of the first tool changing opening 32 is in an arc or trapezoidal structure, which makes the spindle of the machine head 15 more smoothly enter and exit the tool magazine accommodating cavity 31 during tool changing. The arc or trapezoidal structure opening can provide better guidance and containment, which helps to reduce friction and collision during tool changing, thereby improving tool changing efficiency and accuracy. The second tool changing opening 33 is in a rectangular structure, which makes the machine head 15 more easily position and align the tool during tool changing. The rectangular structure opening has better stability and rigidity, which helps to ensure the accuracy and reliability of the tool changing process. In addition, the embodiment also realizes the communication between the first tool changing opening 32 and the second tool changing opening 33. This means that during tool changing, the machine head 15 can enter the tool magazine accommodating cavity 31 for tool changing operation through any one of the first tool changing opening 32 or the second tool changing opening 33. This design improves the flexibility and adaptability of the machine tool, so that the machine head 15 can choose the best tool changing path according to the actual situation. The embodiment improves the smoothness, accuracy and flexibility of the tool changing process through the first tool changing opening 32 and the second tool changing opening 33. At the same time, by realizing the communication between the first tool changing opening 32 and the second tool changing opening 33, the adaptability and practicality of the machine tool are also further improved.

[0046] In an embodiment, referring to Figure 1 and Figure 4, the tool magazine device 3 is an important component of the machine tool, used for storing and managing tools, including a carrying platform 34, a tool magazine cover 35 and a second driving assembly 36. The carrying platform 34 is a platform movably arranged on the tool magazine rail 2, used for supporting and fixing tools. The top of the carrying platform 34 is provided with a plurality of tool mounting positions for the storage of tools. The tool magazine cover 35 covers the carrying platform 34 and forms a tool magazine accommodating cavity 31 together with the carrying platform 34. The tool magazine cover 35 is designed to have sufficient strength and sealing property to protect the tools from interference and damage from the external environment. The tool magazine cover 35 can also be provided with a certain transparency or visibility window, so that the operator can clearly observe the tool condition inside the tool magazine accommodating cavity 31. The second driving assembly 36 is arranged on the base 11 and connected with the carrying platform 34. The second driving assembly 36 is responsible for providing power for the movement of the carrying platform 34. It can include motor, reducer, transmission mechanism and other components, through precise control, the stable and fast movement of the carrying platform 34 on the tool magazine rail 2 can be realized. When tool changing is needed, the second driving assembly 36 drives the carrying platform 34 to move to the appropriate position, so that the head 15 can enter the tool magazine accommodating cavity 31 through the first tool changing opening 32 or the second tool changing opening 33 for tool changing operation.

[0047] During the operation of the machine tool, when tool changing is needed, the head 15 will first move above the first tool changing opening 32 or the second tool changing opening 33. Then, the second driving assembly 36 drives the carrying platform 34 to move to the appropriate position, so that the head 15 can enter the tool magazine accommodating cavity 31 through the corresponding tool changing opening for tool changing operation. After the tool changing is completed, the carrying platform 34 will move back to the original position again for the next tool changing or machining operation. Through the adoption of the carrying platform 34, the tool magazine cover 35 and the second driving assembly 36, stable storage and rapid tool changing of tools are realized.

[0048] In an embodiment, referring to Figure 1 , Figure 4 and Figure 5 , the carrying platform 34 is provided with a plurality of tool magazine accommodating cavities 31, each of which can store one or more tools. A plurality of tool magazine rails 2 are arranged in one-to-one correspondence with the plurality of tool magazine accommodating cavities 31, and the adjacent tool magazine accommodating cavities 31 are separated by a partition plate 37. This design makes the storage and tool changing operation of tools more flexible and efficient. During tool changing, the head 15 is first driven by the first driving assembly 16 to move above the first tool changing opening 32 or the second tool changing opening 33. Then, the second driving assembly 36 is started to drive the carrying platform 34 to move transversely on the tool magazine rail 2, so as to send the required tool magazine 4 to the tool changing position. The carrying platform 34 is provided with a plurality of tool magazine accommodating cavities 31. The head 15 can take out the required tools from the tool magazine accommodating cavities 31, or put the used tools back into the tool magazine accommodating cavities 31.

[0049] By adopting multiple tool magazine tracks 2 and a transversely arranged carrying table 34, efficient storage and rapid tool changing of the tools are achieved. At the same time, by retaining and optimizing the design of the first and second tool changing openings 32 and 33, and by providing multiple tool magazine accommodating cavities 31, the flexibility and adaptability of the machine tool are further improved. This design enables the machine tool to complete the tool changing operation more efficiently and accurately during machining, thereby improving the overall machining efficiency and product quality.

[0050] In an embodiment, referring to Figure 1 and Figure 4 , the tool magazine 4 part of the machine tool is designed to contain two independent accommodating cavities, namely a first accommodating cavity 311 and a second accommodating cavity 312. These two accommodating cavities are used to store different types of tools or spare tools to meet the needs of different tools during machining. The tool magazine tracks 2 correspond to the two accommodating cavities, and the tool magazine tracks 2 are divided into a first track 21 and a second track 22. These two tracks are responsible for guiding the movement and selection of tools in the first accommodating cavity 311 and the second accommodating cavity 312, respectively. The design of the tracks ensures that the tools can be accurately and quickly transported to the designated machining position. In the vertical direction, the first accommodating cavity 311 is arranged between the first track 21 and the cross beam 14, which not only ensures the smooth entry and exit of tools on the first track 21 into the first accommodating cavity 311, but also ensures the structural stability and functionality of the cross beam 14 are not affected. Similarly, the second accommodating cavity 312 is also arranged between the second track 22 and the cross beam 14, following the same design logic.

[0051] During machining, when the machine tool needs to select the appropriate tool according to the machining task, the control system will issue instructions to drive the tool magazine device 3 on the tool magazine track 2 to move along the track to the corresponding tool changing position. By setting two independent accommodating cavities and corresponding tracks, the machine tool can store and quickly select multiple tools at the same time, thereby significantly improving machining efficiency. By arranging the accommodating cavities between the tracks and the cross beam 14, the internal space of the machine tool is fully utilized, making the overall structure more compact and reasonable.

[0052] In an embodiment, referring to Figure 1 , Figure 4 and Figure 5 , the tool magazine cover 35 adopts a box-type structure formed by an enclosing plate. This design not only provides sufficient strength and rigidity, ensuring the stability and durability of the tool magazine 4 system, but also effectively prevents external debris from entering the interior of the tool magazine 4, protecting the tools from damage.

[0053] The side of the tool magazine cover 35 away from the worktable 12 is designed as an open face. This design allows the operator to easily observe and access the interior of the tool magazine 4, facilitating operations such as tool replacement, inspection, and maintenance. At the same time, the open face also facilitates the accurate grabbing and placing of tools by the machine's automated tool changing mechanism (such as a robotic arm, etc.) from the tool magazine 4. Although one side of the tool magazine cover 35 is an open face, the rest remains sealed to prevent external factors such as dust and moisture from adversely affecting the interior of the tool magazine 4. In addition, the open face can be equipped with removable covers or protective covers to provide additional protection when manual operation is not required.

[0054] During operation, the box-shaped structure and open face design of the tool magazine cover 35 together ensure the safety and ease of use of the tool magazine 4 system. On the one hand, the box-shaped structure provides stable support and protection, preventing damage to the tools during storage and movement; on the other hand, the open face design allows the operator to easily access the interior of the tool magazine 4, facilitating necessary operations and maintenance. In addition, this design also improves the overall aesthetics and cleanliness of the machine tool, making the machine tool more reliable and efficient during processing. The machine tool structure provided in this embodiment further improves the stability and ease of use of the tool magazine 4 system through the reasonable design of the tool magazine cover 35, meeting the needs of modern mechanical processing for high precision, high efficiency, and good maintainability.

[0055] In an embodiment, referring to Figure 1 , Figure 2 and Figure 3 , the machine tool further comprises a door curtain 5, which is arranged below the cross beam 14 between the tool magazine device 3 and the worktable 12. The main purpose of this design is to prevent potential safety hazards to the operator during processing due to the rapid movement of the tools or the splashing of debris. At the same time, the door curtain 5 can also reduce noise and dust pollution during machine operation, improving the comfort of the working environment. The door curtain 5 is usually made of lightweight, durable, and easy-to-clean materials, such as transparent or semi-transparent plastic film, canvas, or special synthetic fibers, etc. These materials not only have good protective properties, but also ensure that the operator can clearly observe the operation of the machine tool inside, facilitating monitoring and adjustment. The structure of the door curtain 5 is usually designed to be retractable or detachable, so as to facilitate cleaning, replacement, or maintenance when needed.

[0056] The door curtain 5 is controlled by manual or electric means to lift or open and close. During the operation of the machine tool, the operator can adjust the position and state of the door curtain 5 at any time according to actual needs. In addition, the cleaning and maintenance of the door curtain 5 is also very convenient, which can maintain its cleanliness and transparency by wiping it with a damp cloth regularly. When the machine tool is in operation, the door curtain 5 will automatically or manually lower to the appropriate position to completely close the area between the tool magazine device 3 and the workbench 12. This not only effectively prevents the splashing of tools and debris from causing harm to the operator, but also reduces noise and dust pollution during the operation of the machine tool. At the same time, the transparent or semi-transparent design of the door curtain 5 also ensures that the operator can clearly observe the operation inside the machine tool, which is convenient for monitoring and adjusting.

[0057] In an embodiment, referring to Figure 1 , Figure 2 and Figure 3 , a door curtain 5 with a complex structure is added to effectively isolate different areas inside the machine tool. The door curtain 5 includes a connecting plate 51, a shielding curtain 52, a shielding piece 53, a guide rail, and a third driving assembly 55. The connecting plate 51 is the main support structure of the door curtain 5, which is firmly installed on the cross beam 14. The design of the connecting plate 51 enables the door curtain 5 to be stably suspended inside the machine tool, while providing mounting points for other components. The shielding curtain 52 is the main part of the door curtain 5, which is connected to the connecting plate 51 and extends from the side of the cross beam 14 to the side of the base 11. The main function of the shielding curtain 52 is to shield and isolate different areas inside the machine tool, especially the area where the workbench 12 is installed and the area where the tool magazine device 3 is installed. The shielding piece 53 is an additional structure arranged on the shielding curtain 52, which is spaced apart along the direction from the cross beam 14 to the base 11. The guide rod 54 is an auxiliary structure connected to the connecting plate 51, which is located on the side of the shielding curtain 52 close to the column 13. The guide rod 54 extends from the cross beam 14 to the base 11 and passes through each shielding piece 53. The main function of the guide rod 54 is to guide and support the shielding piece 53, ensuring that they can be smoothly opened or closed. The third driving assembly 55 is the core power component of the door curtain 5, which is installed on the cross beam 14 and connected to the shielding curtain 52. The third driving assembly 55 drives several shielding pieces 53 to open or close by driving the shielding curtain 52. This design enables the door curtain 5 to flexibly adjust the isolation state of different areas as needed.

[0058] During operation, when different areas inside the machine tool need to be isolated, the third drive assembly 55 will start and drive the curtain 52 to move along the guide rod 54. With the movement of the curtain 52, the shutter 53 will also open or close accordingly, thereby achieving the isolation of different areas. This design not only improves the safety of the machine tool, but also effectively reduces the noise and dust pollution during the operation of the machine tool. In addition, the complex structure of the door curtain 5 also makes it more flexible to adapt to different working environments and operation requirements. For example, when the tool needs to be frequently replaced or the workbench 12 needs to be adjusted, the door curtain 5 can be quickly opened or closed to improve work efficiency. The door curtain 5 provided in this embodiment further improves the safety and operation convenience of the machine tool. This design not only meets the needs of modern mechanical processing for high precision, high efficiency and good working environment, but also provides more possibilities for the future development of machine tools.

[0059] In an embodiment, referring to Figure 1 、 In an embodiment, referring to Figure 5 A rotatable tool magazine door 38 is provided on the tool magazine device 3 to cover the first tool changing opening 32, so as to effectively seal and protect the first tool changing opening 32. The tool magazine door 38 is designed to be rotatable and can cover the first tool changing opening 32. The first tool changing opening 32 is an opening in the machine tool for changing tools, which can reduce noise and dust pollution during the operation of the machine tool and improve the comfort of the working environment. The tool magazine door 38 is usually made of lightweight, durable and easy-to-clean materials such as metal or special synthetic materials. These materials not only have good protective properties, but also ensure that the tool magazine door 38 maintains stable structure and performance during long-term use. The structural design of the tool magazine door 38 usually includes a rotatable hinge or shaft, so that it can be easily opened or closed. In addition, the surface of the tool magazine door 38 can be specially treated, such as spraying anti-rust paint or installing sound insulation materials, to improve its durability and sound insulation effect.
