Description

Technical Field

[0001] This utility model relates to the field of machine tool magazine technology, specifically to a highly versatile tool holder structure for gantry machining centers. Background Technology

[0002] A tool magazine system is a device that provides the necessary tool storage and changing capabilities for automated machining processes. Its automatic tool changer and tool magazine, capable of storing multiple tools, have transformed traditional, human-intensive production methods. Through computer program control, various machining requirements can be met, such as milling, drilling, boring, and tapping, significantly reducing machining time and production costs.

[0003] The existing tool magazines of gantry machining centers have insufficient tool length or number of tools, which cannot meet the machining needs of complex processes. At the same time, the existing tool changing methods are inefficient. Utility Model Content

[0004] To address the technical problems in existing technologies, this utility model provides a highly versatile tool holder structure for gantry machining centers, including a welded tool holder assembly and metal tool holders for storing tools. The welded tool holder assembly is fixedly mounted on the machine tool's worktable. Multiple metal tool holders are spaced apart on top of the welded tool holder assembly and arranged along the X-axis of the machine tool. The system also includes multiple photoelectric switches, each corresponding to a metal tool holder. The photoelectric switches are mounted on the welded tool holder assembly and connected to the metal tool holders. After a tool change, the photoelectric switches disconnect, and the tool separates from the metal tool holder.

[0005] Furthermore, both ends of the welded component of the knife holder are equipped with protective covers by a drive mechanism, and the protective covers are opened or closed by the drive mechanism.

[0006] Furthermore, the driving mechanism includes a connecting rod and a cylinder. The two ends of the connecting rod are respectively hinged to the side of the protective cover and the side of the welded component of the tool holder. The cylinder is installed at the bottom of the welded component of the tool holder, and the telescopic end of the cylinder is hinged to the connecting rod through an L-shaped connector. The protective cover closes or opens multiple metal tool holders under the telescopic action of the cylinder.

[0007] Furthermore, it also includes two limit switches, which are staggered at both ends of the welded component of the knife holder via a first mounting plate and a second mounting plate, respectively. When the limit switch on the first mounting plate contacts the protective cover, the protective cover completely closes the multiple metal knife clips. When the limit switch on the second mounting plate contacts the protective cover, the protective cover completely opens the multiple metal knife clips.

[0008] Furthermore, the first mounting plate is located on the inner side of the welded component of the tool holder near the workpiece to be processed, and the second mounting plate is located on the outer side of the welded component of the tool holder.

[0009] Beneficial effects:

[0010] 1. This utility model solves the problems of insufficient tool length or insufficient number of tools by using multiple metal tool holders and their arrangement along the X-axis and the setting of photoelectric switches. It also has fast tool changing speed and strong versatility. In addition, the tool arrangement and machine tool adjustment are convenient. Various tools for different purposes can be arbitrarily combined according to the milling process requirements of specific workpieces, thereby meeting the processing needs of complex processes.

[0011] 2. In this utility model, the driving mechanism and protective cover can protect the cutting tool during processing; the connecting rod, cylinder and L-shaped connector can be used to conveniently and quickly close or open the protective cover by extending and retracting the cylinder.

[0012] 3. The two limit switches in this utility model make it easy to confirm whether the protective cover is completely closed or open, thereby improving the protection effect on the tool or facilitating the replacement of the tool. Attached Figure Description

[0026] This utility model provides a highly versatile tool holder structure for gantry machining centers, such as... Figures 1 to 4 As shown, the tool holder includes a welded component 1 and a metal tool holder 2 for storing cutting tools. The welded component 1 is fixedly mounted on the worktable of the machine tool. Multiple metal tool holders 2 are spaced apart on the top of the welded component 1 and arranged along the X-axis of the machine tool on the welded component 1. The tool holder also includes multiple photoelectric switches 4, each corresponding to one of the metal tool holders 2. The photoelectric switches 4 are mounted on the welded component 1 and connected to the metal tool holders 2. After tool changing, the photoelectric switches 4 are disconnected, and the cutting tool is separated from the metal tool holder 2.

[0027] In this embodiment, by using multiple metal tool holders 2 and their arrangement along the X-axis and the setting of photoelectric switches 4, the problems of insufficient tool length or insufficient number of tools can be solved. The tool changing speed is fast and the versatility is strong. In addition, the tool arrangement and machine tool adjustment are convenient. Various tools for different purposes can be arbitrarily combined according to the milling process requirements of specific workpieces, thereby meeting the processing needs of complex processes.

[0028] In this utility model, preferably, such as Figures 1 to 4As shown, both ends of the welded component 1 of the tool holder are rotatably mounted with protective covers 5 via a drive mechanism. The protective covers 5 close or open multiple metal tool clips 2 under the action of the drive mechanism. The drive mechanism includes a connecting rod 6 and a cylinder 7. The two ends of the connecting rod 6 are respectively hinged to the side of the protective cover 5 and the side of the welded component 1 of the tool holder. The cylinder 7 is installed at the bottom of the welded component 1 of the tool holder, and the telescopic end of the cylinder 7 is hinged to the connecting rod 6 via an L-shaped connector 8. The protective cover 5 closes or opens multiple metal tool clips 2 under the telescopic action of the cylinder 7.

[0029] In this embodiment, the driving mechanism and protective cover 5 can protect the cutting tool during machining. The connecting rod 6, cylinder 7 and L-shaped connector 8 can be used to conveniently and quickly close or open the protective cover 5 by extending and retracting the cylinder 7.

[0030] In this utility model, preferably, such as Figure 1 , Figure 2 and Figure 4 As shown, it also includes two limit switches 3. The two limit switches 3 are respectively distributed at both ends of the tool holder welded part 1 through the first mounting plate 9 and the second mounting plate 10. When the limit switch 3 located on the first mounting plate 9 contacts the protective cover 5, the protective cover 5 completely closes the multiple metal tool clips 2. When the limit switch 3 located on the second mounting plate 10 contacts the protective cover 5, the protective cover 5 completely opens the multiple metal tool clips 2. The first mounting plate 9 is located on the inner side of the tool holder welded part 1 near the workpiece to be processed, and the second mounting plate 10 is located on the outer side of the tool holder welded part 1.

[0031] In this embodiment, the setting of two limit switches 3 makes it easy to confirm whether the protective cover 5 is completely closed or open, thereby improving the protection effect on the tool or facilitating the replacement of the tool.

[0032] Working principle:

[0033] like Figures 1 to 4 As shown, during use, various tools for different purposes can be arbitrarily combined according to the milling process requirements of the specific workpiece. After one tool completes the milling task, the tool change point is moved according to the program, and the protective cover 5 is quickly opened by the retraction of the cylinder 7 to change to the second tool. Before changing the tool, it is necessary to ensure that the protective cover 5 is fully open, that is, the protective cover 5 is in contact with the limit switch 3 located on the second mounting plate 10. Then, the tool change is completed according to the photoelectric switch 4. Finally, the cylinder 7 extends to drive the protective cover 5 to close, and the protective cover 5 contacts the limit switch 3 located on the first mounting plate 9 to indicate that the protective cover 5 is closed in place.

[0034] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0035] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
