Description

Technical Field

[0001] This utility model belongs to the field of CNC machine tool technology, specifically relating to an automatic opening and closing tool magazine door structure for CNC machine tools. Background Technology

[0002] In modern manufacturing, CNC machine tools are key equipment, and their performance and stability play a decisive role in production efficiency and product quality. The tool magazine, as an important component of CNC machine tools, undertakes the crucial task of storing and exchanging cutting tools. However, in actual machining processes, the tool magazine and tool change positions on CNC machine tools often fail to contain the large amounts of waste material generated during machining. This waste material easily splashes and adheres to the tool magazine and tool holder. Once the tool holder is contaminated, the connection accuracy between the tool holder and the spindle decreases, affecting the tool installation accuracy and cutting stability. This not only reduces machining accuracy and makes it difficult to guarantee product quality, but may also lead to safety hazards such as tool loosening and falling off. In severe cases, it can even damage the machine tool, increase maintenance costs and downtime, and affect production schedules. Utility Model Content

[0003] (1) Technical problems to be solved In view of the shortcomings of the existing technology, the purpose of this utility model is to provide an automatic opening and closing tool magazine door structure for CNC machine tools. This structure aims to solve the problem that a large amount of waste and slag generated during the machining process of existing CNC machine tools are easily splashed around and attached to the tool magazine and tool holder.

[0004] (2) Technical solution To solve the above-mentioned technical problems, this utility model provides an automatic opening and closing tool magazine door structure for CNC machine tools. The structure includes a base, a frame, and a tool magazine support that moves between the tool magazine position and the tool changing position on the base. The tool magazine support includes a drive frame and a storage frame. A connecting plate is fixedly connected between the drive frame and the storage frame. A linkage mechanism is installed on the connecting plate. The tool magazine door is installed on the side of the linkage mechanism near the tool changing position. A drive component is installed between the linkage mechanism and the tool magazine support. A blocking rod is fixedly connected to the end of the base near the tool magazine support. When the tool magazine support moves to the tool changing position to change tools, the linkage mechanism lowers the tool magazine door through the drive component. When the tool magazine support moves into the tool magazine position, the linkage mechanism raises the tool magazine door through the blocking rod.

[0005] Preferably, the linkage mechanism includes a first link, a second link, a third link, and a fourth link. One end of the first link is fixedly connected to a downwardly bent guide portion, and the other end of the first link is rotatably connected to a connecting plate. One end of the third link and the fourth link are both rotatably connected to the tool magazine door, and the other ends of the third link and the fourth link are both rotatably connected to the connecting plate. One end of the second link is rotatably connected to the first link, and the other end of the second link is rotatably connected to the extension end of the third link.

[0006] Furthermore, the third link, the fourth link, the tool magazine door, and the connecting plate form a parallelogram structure, and the two rotation points of the third link, the fourth link, and the connecting plate are vertical.

[0007] Furthermore, there are two connecting plates, two linkage mechanisms, and two driving components, which are respectively located on the left and right sides of the base.

[0008] Furthermore, the driving component is a spring, with one end of the driving component rotatably connected to the fourth link and the other end of the driving component rotatably connected to the driving frame.

[0009] Furthermore, the blocking rod includes fixed plates that are fixedly connected to the left and right sides of the upper surface of the base, and a round rod is fixedly connected between the two fixed plates.

[0010] Furthermore, a door frame is fixedly connected to the frame between the tool magazine position and the tool change position, and the door frame has an entrance and exit corresponding to the tool magazine bracket.

[0011] (3) Beneficial effects Compared with the prior art, the beneficial effects of this utility model are as follows: 1. This utility model provides a tool magazine bracket with a tool magazine door between the tool magazine position and the tool changing position of a CNC machine tool. Through the cooperation of a linkage mechanism, a driving component and a blocking rod, the tool magazine door can be mechanically linked. When the tool magazine bracket exits the tool magazine position, the tool magazine door can automatically open and close, preventing waste material and slag from splashing onto the tool magazine and tool holder. At the same time, there is no need to wait for the tool magazine door to open, thus improving the opening and closing efficiency of the tool magazine door. 2. This utility model constructs a parallelogram structure by forming the third and fourth links of the linkage mechanism, the tool magazine door, and the connecting plate. Furthermore, the two rotation points of the third and fourth links and the connecting plate are vertical, which allows the tool magazine door to rise and fall vertically and fit tightly against the door frame, thereby improving the sealing and protection effect and better protecting the tool handle.

[0020] This specific embodiment is an automatic opening and closing tool magazine door structure for a CNC machine tool, and its structural schematic diagram is shown below. Figures 1-7 As shown, the structure includes a base 1, a frame 2, and a tool magazine support 4 that moves between the tool magazine position 3 and the tool change position 5 on the base 1. After the tool magazine support 4 moves, it provides tools for the machining head on the frame 2. This is prior art and will not be described in detail here. The tool magazine support 4 includes a drive frame 6 and a storage rack 7. The drive frame 6 is driven by components inside the machine tool. The storage rack 7 is used to store tools. A connecting plate 8 is fixedly connected between the drive frame 6 and the storage rack 7. A linkage mechanism 9 is installed on the connecting plate 8. A tool magazine door 10 is installed on the side of the linkage mechanism 9 near the tool change position 5. A drive element 11 is installed between the linkage mechanism 9 and the tool magazine support 4. A blocking rod 12 is fixedly connected to one end of the base 1 near the tool magazine support 4. When the tool magazine support 4 moves to the tool change position 5 to change tools, the linkage mechanism 9 lowers the tool magazine door 10 through the drive element 11. When the tool magazine support 4 moves into the tool magazine position 3, the linkage mechanism 9 raises the tool magazine door 10 through the blocking rod 12.

[0021] In order to make the linkage mechanism 9 perform stable actions, such as Figure 2 and Figure 3As shown: In this embodiment, the linkage mechanism 9 includes a first link 901, a second link 902, a third link 903, and a fourth link 904. One end of the first link 901 is fixedly connected to a downwardly bent guide part 905, and the other end of the first link 901 is rotatably connected to the connecting plate 8. One end of the third link 903 and the fourth link 904 are both rotatably connected to the knife magazine door 10, and the other ends of the third link 903 and the fourth link 904 are both rotatably connected to the connecting plate 8. One end of the second link 902 is rotatably connected to the first link 901, and the other end of the second link 902 is rotatably connected to the extension end of the third link 903.

[0022] The rotating parts of the first link 901, the second link 902, the third link 903 and the fourth link 904 can be connected by pins. Pressing down the first link 901 can press down the second link 902. Pressing down the second link 902 can press down one end of the third link 903 and cause the other end of the third link 903 to lift up.

[0023] To make the blade magazine door 10 rise vertically, as Figure 3 and Figure 5 As shown: In this embodiment, the third link 903, the fourth link 904, the knife magazine door 10 and the connecting plate 8 form a parallelogram structure, and the two rotation points of the third link 903 and the fourth link 904 and the connecting plate 8 are vertically aligned.

[0024] like Figure 3 and Figure 5 As shown: In this embodiment, there are two connecting plates 8, two linkage mechanisms 9, and two driving components 11. The two connecting plates 8, two linkage mechanisms 9, and two driving components 11 are respectively arranged on the left and right sides of the base 1. In this way, the two linkage mechanisms 9 support the tool magazine door 10, and the up and down movement of the tool magazine door 10 is more stable.

[0025] In order for the drive unit 11 to automatically pull the tool magazine door 10 downward, such as Figure 5 and Figure 6 As shown: In this embodiment, the driving component 11 is a spring. One end of the driving component 11 is rotatably connected to the fourth link 904, and the other end of the driving component 11 is rotatably connected to the driving frame 6. After the fourth link 904 rotates upward, it can stretch the spring to store energy, preparing for the next door opening.

[0026] In order to better block the guide part 905 of the first link 901, such as Figure 1 and Figure 2 As shown: In this embodiment, the blocking rod 12 includes a fixing plate 1201 fixedly connected to the left and right sides of the upper surface of the base 1, and a round rod 1202 is fixedly connected between the two fixing plates 1201.

[0027] like Figure 2 and Figure 4 As shown: In this embodiment, a door frame 13 is fixedly connected to the frame 2 between the tool magazine position 3 and the tool change position 5. The door frame 13 has an inlet and outlet 14 corresponding to the tool magazine support 4. In this way, the tool magazine support 4 can enter and exit within the inlet and outlet 14. The top of the door frame 13 is closed, and the inlet and outlet 14 is on the lower side. When the tool magazine support 4 moves backward to the tool magazine position 3, the tool magazine door 10 will rise vertically and fit tightly against the door frame 13, thereby better blocking the waste.

[0028] Working principle: A tool magazine support 4 with a tool magazine door 10 is set between the tool magazine position 3 and the tool change position 5 of the CNC machine tool. When the tool magazine support 4 moves forward to the tool change position 5 to change the tool, the guide part 905 of the first link 901 leaves the fixed blocking rod 12. At this time, the drive component 11 will retract and pull the fourth link 904 downward. Since the third link 903, the fourth link 904, the tool magazine door 10 and the connecting plate 8 form a parallelogram structure, the tool magazine door 10 will automatically descend. At the same time, the first link 901 will tilt upward through the second link 902. When the tool magazine support 4 moves backward to the tool magazine position 3, the guide part 905 of the first link 901 will be squeezed by the blocking rod 12. At this time, the second link 902 will press down one end of the third link 903, and the lever structure will cause the tool magazine door 10 at the other end of the third link 903 to rise and stretch the drive member 11, preparing for the next opening. Since the third link 903 and the fourth link 904 are vertically connected to the two rotation points of the connecting plate 8, the tool magazine door 10 will rise vertically until it is tightly fitted with the door frame 13 between the tool magazine position 3 and the tool changing position 5, so that the waste and slag in the machining process cannot enter the tool holder part.

[0029] All technical features in this embodiment can be freely combined according to actual needs.

[0030] The above embodiments are preferred implementations of this utility model. In addition, this utility model can also be implemented in other ways. Any obvious substitutions without departing from the concept of this technical solution are within the protection scope of this utility model.
