Description

Technical Field

[0001] This utility model relates to the field of machining center technology, and more specifically, to a five-axis machining center with a tool magazine. Background Technology

[0002] A five-axis machining center, also known as a five-axis linkage machining center, is a high-tech, high-precision machining center specifically designed for machining complex curved surfaces. A five-axis machining center has five axes: X, Y, Z, A, and C. Among them, X, Y, and Z are three translation axes, and A and C are two rotation axes. The five-axis linkage machining is achieved through the XYZ and AC axes.

[0003] Currently, five-axis machining centers require the use of multiple tools when machining workpieces. To save tool change time and improve machining efficiency, five-axis machining centers are usually equipped with tool magazines. Tool magazines can store multiple tools, allowing tools to be replaced at any time and reducing downtime caused by tool wear or damage. However, existing tool magazines are generally installed on one side of the five-axis machining center column, which not only takes up space, but also, when the five-axis machining center is working, the waste chips generated during milling of the workpiece and impurities in the air can easily splash onto the tools in the tool magazine, thus affecting the retrieval of tools. Utility Model Content

[0004] 1. Technical problems to be solved

[0026] Example:

[0027] Please see Figure 1-3 A five-axis machining center with a tool magazine includes a worktable 1, a support frame 2 fixedly connected to the top of the worktable 1, a three-axis moving module 3 fixedly connected to the top of the support frame 2, a spindle mechanism 4 fixedly connected to the three-axis moving module 3, a cradle rotating device 5 fixedly connected to the top of the worktable 1, a horizontal turntable 6 fixedly connected inside the cradle rotating device 5 and corresponding to the spindle mechanism 4, a fixed base 7 fixedly connected to the top of the worktable 1, a cylinder 8 fixedly connected to the fixed base 7, a slide 9 fixedly connected to the output end of the cylinder 8 and slidably connected to the fixed base 7, a servo motor 10 fixedly connected to the top of the slide 9, a disc tool holder 11 fixedly connected to the output end of the servo motor 10, and a disc tool holder 11. 1 is located inside the support frame 2. A fixed frame 12 is fixedly connected between the symmetrical side walls of the support frame 2. A follower arc sleeve 13 is slidably connected to the fixed frame 12 and is fitted on the outside of the disc tool holder 11. A fixed rod 14 is fixedly connected to the follower arc sleeve 13. A rotating shaft 15 is rotatably connected to one end of the fixed rod 14 and is rotatably connected to the middle of the worktable 1. Two telescopic arc sleeves 16 are slidably connected inside the follower arc sleeve 13 and are fitted on the outside of the disc tool holder 11. Two sliding grooves 17 are opened on the fixed frame 12. Rolling shafts 18 are rotatably connected to the top of the two telescopic arc sleeves 16 and are slidably connected to the two sliding grooves 17 respectively.

[0028] In this embodiment, multiple cutting tools are placed on the disc tool holder 11. When machining a workpiece, the workpiece is fixed on the horizontal turntable 6, and the cylinder 8 pushes the slide 9 to extend the disc tool holder 11 forward. The disc tool holder 11 drives the follower arc sleeve 13 to move through the rotating shaft 15 and the fixed rod 14. The follower arc sleeve 13 slides on the fixed frame 12 and follows the movement of the disc tool holder 11, always protecting the cutting tools on the disc tool holder 11. During the movement of the follower arc sleeve 13, it drives the two telescopic arc sleeves 16 to move. The two telescopic arc sleeves 16 retract and open into the follower arc sleeve 13 through the sliding connection of the two rolling shafts 18 and the two sliding grooves 17, so that the cutting tools are exposed after the disc tool holder 11 moves. The servo motor 10 controls the disc tool holder 11 to rotate the required cutting tool to the exposed position. The three-axis movement module 3 controls the spindle mechanism 4 to move to correspond with the cutting tool for picking. After the cutting tool is picked up, the cylinder 8 controls the slide 9 and the disc tool holder 11. The follower arc sleeve 13 moves and resets with the disc tool holder 11. The two telescopic arc sleeves 16 are slidably connected in the two slide grooves 17 through the two rolling shafts 18. After the two telescopic arc sleeves 16 are reset, they surround and protect the multiple tools on the disc tool holder 11. Then, the cradle rotation device 5 and the horizontal turntable 6 cooperate to rotate the workpiece and adjust the workpiece processing position. The three-axis moving module 3 controls the spindle mechanism 4 to move in three axes. The spindle mechanism 4 controls the tool to rotate and perform multi-position milling on the workpiece. When the tool needs to be replaced, the cylinder 8 pushes the disc tool holder 11 forward again to expose the tool. The spindle mechanism 4 first places the tool in the empty position of the disc tool holder 11, and then selects the required tool to process the workpiece. The rotating shaft 15 is coaxial with the disc tool holder 11. The follower arc sleeve 13 is rotatably connected to the disc tool holder 11 through the rotating shaft 15 at the front end of the fixed rod 14 and will not rotate with the disc tool holder 11.

[0029] Specifically, the top end of the follower arc sleeve 13 is fixedly connected to a slider group 19, and the slider group 19 is slidably connected to the fixed frame 12.

[0030] In this embodiment, the follower arc sleeve 13 slides on the fixed frame 12 via the slider group 19, and the slider group 19 keeps the movement of the follower arc sleeve 13 stable.

[0031] Specifically, one end of a telescopic arc sleeve 16 is fixedly connected to a sealing sleeve 20, and the sealing sleeve 20 matches one end of another telescopic arc sleeve 16.

[0032] In this embodiment, when the two telescopic arc sleeves 16 surround the tool on the disc tool holder 11, the sealing sleeve 20 is located between the two telescopic arc sleeves 16 to prevent gaps from forming between the two telescopic arc sleeves 16 that could allow impurities to enter.

[0033] Specifically, a protective shell 21 is fixedly connected to the top of the slide 9, and the servo motor 10 is located inside the protective shell 21.

[0034] In this embodiment, the protective shell 21 is used to protect the servo motor 10 and prevent damage to the servo motor 10.

[0035] Specifically, a guide block 22 is fixedly connected to the top of the fixed base 7, and a slide bar 23 is fixedly connected to the bottom of the slide base 9, with the slide bar 23 slidably connected within the guide block 22.

[0036] In this embodiment, when the cylinder 8 controls the slide 9 to move back and forth, the slide 9 drives the slide bar 23 to slide within the guide block 22. The slide bar 23 and the guide block 22 enable the slide 9 to slide stably on the fixed seat 7.

[0037] Specifically, a slag discharge channel 24 is provided on one side of the workbench 1, and the slag discharge channel 24 corresponds to the horizontal turntable 6.

[0038] In this embodiment, the workpiece is milled on the horizontal turntable 6, and the impurities generated during milling fall into the slag discharge channel 24 for discharge.

[0039] Working Principle: When machining a workpiece, cylinder 8 pushes slide 9 forward on fixed base 7. Slide 9 drives disc tool holder 11 forward via servo motor 10. During the movement of disc tool holder 11, follower arc sleeve 13 slides on fixed base 12. Follower arc sleeve 13 always follows disc tool holder 11 to protect the rear tool. At the same time, two telescopic arc sleeves 16 move forward with disc tool holder 11, causing two rolling shafts 18 to slide in two grooves 17. When the two rolling shafts 18 move away, the two telescopic arc sleeves 16 retract into follower arc sleeve 13, opening the front of disc tool holder 11 and exposing the tool at the front. Servo motor 10 controls disc tool holder 11 to rotate, providing the required tool to spindle mechanism 4 at the exposed position. Three-axis movement module 3 controls spindle mechanism 4 to move to the corresponding position to pick up the tool. After the tool is picked up, an empty space is created on disc tool holder 11 for the spindle machine. When the tool is replaced in the subsequent mechanism 4, the cylinder 8 controls the slide 9 to reset. The slide 9 drives the servo motor 10 and the disc tool holder 11 to reset. During the reset of the disc tool holder 11, the follower arc sleeve 13 is also reset. The two telescopic arc sleeves 16 extend outward through the sliding connection of the two rolling shafts 18 and the two sliding grooves 17, thereby surrounding and protecting the tool in front of the disc tool holder 11 to prevent impurities from adhering to the tool and affecting its use. Then, the three-axis moving module 3 controls the spindle mechanism 4 to move in three axes. The cradle rotating device 5 and the horizontal turntable 6 cooperate to rotate the workpiece and adjust the workpiece processing position. The spindle mechanism 4 controls the tool to rotate to perform multi-position milling on the workpiece. When the spindle mechanism 4 needs to replace the tool, the disc tool holder 11 provides the spindle mechanism 4 with space and tool in the same way as above. The spindle mechanism 4 first places the unused tool in the reserved space, and then selects the required tool to process the workpiece.

[0040] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model based on the technical solution and its improved concept should be covered within the protection scope of the present utility model.
