Each of the first placement groove 11, the second placement groove 21 and the third placement groove 31 is used for clamping and installing the tool sleeve 40, and the tool sleeve 40 is used to install the tool; the tool sleeve 40 includes a first sleeve body 41, a second sleeve body 42 and a third sleeve body 43 connected in sequence, and the second sleeve body 42 is provided with a clamping groove 421, the first sleeve body 41 is used to install the tool, and the third sleeve body 43 is used to be installed on the machining spindle of the machining center; or the third sleeve body 43 is used to install the tool, and the first sleeve body 41 is used to be installed on the machining spindle of the machining center; the first sleeve body 41, the second sleeve body 42 and the third sleeve body 43 can be a split structure or an integrated structure; The first cutter disc 10, the second cutter disc 20 and the third cutter disc 30 rotate through the rotating assembly 50 to move the cutter on the cutter disc structure to the preset tool changing position; the rotating assembly 50 is installed with a lifting assembly 60, and the lifting assembly 60 is used to drive the third cutter disc 30 to perform lifting movement in the vertical direction. In this embodiment, the number of the first placement slot 11, the second placement slot 21 and the third placement slot 31 is not limited; illustratively, the first placement slot 11, the second placement slot 21 and the third placement slot 31 are eight. By setting a plurality of tool sleeves 40, various types of cutters can be placed in the corresponding tool sleeves 40 respectively, and the first cutter disc 10, the second cutter disc 20 and the third cutter disc 30 can be provided with a mark, which is used to distinguish the cutters on the cutter disc, and the mark can be a number, a letter or other symbol.

[0024] It should be noted that the present invention provides a multi-layer cutter disc structure, in which the first cutter disc 10, the second cutter disc 20 and the third cutter disc 30 are sequentially arranged in layers along the vertical direction downward, and the tool sleeve 40 is clamped and installed through the first placement groove 11, the second placement groove 21 and the third placement groove 31, thereby increasing the capacity of the tool; in addition, since the second placement groove 21 is staggered with the first placement groove 11 and the third placement groove 31, respectively, the multi-layer cutter disc structure has a compact structure and occupies a small volume; through the rotation action of the rotating component 50 and the lifting action of the lifting component 60, the tool on the cutter disc structure can be quickly moved to the preset tool changing position.

[0025] like Figure 1-3As shown, the rotating assembly 50 includes a frame 501, a rotating shaft 502 is rotatably connected to the frame 501, and a rotating motor 503 for driving the rotating shaft 502 to rotate is also installed on the frame 501, and the rotating shaft 502 is used to drive the first cutter disc 10, the second cutter disc 20 and the third cutter disc 30 to rotate. In this embodiment, the frame 501 is a frame structure. Through the setting of the frame 501, the multi-layer cutter disc structure provided by the present invention can be installed in a machining center to provide the machining center with tools for product processing. A driving wheel is fixedly installed on the output shaft of the rotating motor 503, and a driven wheel is sleeved on the rotating shaft 502. The driving wheel and the driven wheel are connected by a belt.

[0026] It should be noted that, through the driving action of the rotating motor 503, the driving wheel is driven to rotate, driving the belt to move; since the driving wheel and the driven wheel are connected by a belt, the belt drives the driven wheel to rotate, and then drives the rotating shaft 502 to rotate, thereby driving the first cutter disc 10, the second cutter disc 20 and the third cutter disc 30 to rotate, moving the tool on the cutter disc structure to the preset tool changing position, and assembling the tool to the machining spindle of the machining center through an external intelligent robot or manipulator.

[0027] like Figure 1-3 As shown, the rotating shaft 502 is connected to a third support shaft 504, and a third support plate 505 fixedly connected to the third cutter disc 30 is installed on the third support shaft 504; in this embodiment, the third support shaft 504 is fixedly connected to the rotating shaft 502, and can be fastened by screws or fixed by welding; the third support plate 505 plays a supporting role, effectively supports the first cutter disc 10, the second cutter disc 20 and the third cutter disc 30, and is also convenient for driving the third cutter disc 30 to rotate; The third cutter disc 30 is connected to a second support shaft 506, and a second support disc 507 fixedly connected to the second cutter disc 20 is installed on the second support shaft 506; in the present embodiment, the second support shaft 506 is fixedly connected to the third cutter disc 30, and can be fastened by screws or fixed by welding; the second support disc 507 plays a supporting role, effectively supports the first cutter disc 10 and the second cutter disc 20, and is also convenient for driving the third cutter disc 30 to rotate; The second cutter disc 20 is connected to a first support shaft 508, and a first support disc 509 movably connected to the first cutter disc 10 is mounted on the first support shaft 508. In this embodiment, the first support shaft 508 is fixedly connected to the second cutter disc 20, and can be fastened by screws or fixed by welding; the first support disc 509 plays a supporting role, effectively supports the first cutter disc 10, and is also convenient for driving the first cutter disc 10 to rotate; It should be noted that since the multi-layer cutter disc structure is disassembled, a single-layer cutter disc structure or a double-layer cutter disc structure can be installed according to the complexity of product processing to adapt to a variety of different processing conditions, thereby improving the adaptability of the multi-layer cutter disc structure.

[0028] like Figure 1-3 As shown, the first support shaft 508, the second support shaft 506 and the third support shaft 504 are all hollow shafts, and a rotating disk 510 is installed between the rotating shaft 502 and the third support shaft 504. It should be noted that the setting of the rotating disk 510 can better balance the rotation of the first cutter disc 10, the second cutter disc 20 and the third cutter disc 30. Since the first support shaft 508, the second support shaft 506 and the third support shaft 504 are all hollow shafts, the overall weight of the multi-layer cutter disc structure can be reduced, and it is also convenient for the telescopic rod of the lifting cylinder 61 to pass through.

[0029] like Figure 3-9 As shown, the first placement groove 11 is provided with a first snap ring 12, the second placement groove 21 is provided with a second snap ring 22, and the third placement groove 31 is provided with a third snap ring 32; the outer wall of the tool sleeve 40 is provided with a snap groove 421, and the snap groove 421 is respectively snap-fitted with the first snap ring 12, the second snap ring 22 and the third snap ring 32; Among them, the first clamping ring 12, the second clamping ring 22 and the third clamping ring 32 are all open ring structures. The first cutter disc 10 is provided with a first opening 13 that passes through the first clamping ring 12, the second cutter disc 20 is provided with a second opening 23 that passes through the second clamping ring 22, and the third cutter disc 30 is provided with a third opening 33 that passes through the third clamping ring 32.

[0030] It should be noted that since the first clamping ring 12, the second clamping ring 22 and the third clamping ring 32 are all open ring structures, it is convenient to snap-fit ​​and install the tool sleeve 40 onto the first tool disc 10, the second tool disc 20 or the third tool disc 30; through the setting of the first opening 13, the second opening 23 and the third opening 33, stress concentration restrictions can be prevented when the tool sleeve 40 is snap-fitted and installed, thereby increasing the elasticity of the first placement groove 11, the second placement groove 21 and the third placement groove 31.

[0031] like Figure 5 , Figure 7 and Fig. 9 As shown, the first cutter disc 10 is provided with a first notch 14 that is connected to the first clamping ring 12, the second cutter disc 20 is provided with a second notch 24 that is connected to the second clamping ring 22, and the third cutter disc 30 is provided with a third notch 34 that is connected to the third clamping ring 32. It should be noted that, by providing the first notch 14, the second notch 24 and the third notch 34, the elasticity of the first placement groove 11, the second placement groove 21 and the third placement groove 31 can be further enhanced, so as to facilitate the clamping installation of the cutter sleeve 40.

[0032] like Figure 5 , Figure 7 and Fig. 9 As shown, the number of the first notch 14, the second notch 24 and the third notch 34 is set to two, and the first notch 14, the second notch 24 and the third notch 34 are all set in a V shape. It should be noted that, since the number of the first notch 14, the second notch 24 and the third notch 34 is set to two, the first placement groove 11, the second placement groove 21 and the third placement groove 31 are better expanded when the knife sleeve 40 is installed, and the knife sleeve 40 is smoothly clamped and installed; since the first notch 14, the second notch 24 and the third notch 34 are all set in a V shape, stress concentration can be prevented when the knife sleeve 40 is clamped and installed, and the first placement groove 11, the second placement groove 21 and the third placement groove 31 are prevented from being damaged.

[0033] like Figure 5 , Figure 7 and Fig. 9 As shown, the first two ends of each first snap ring 12 are provided with first bevels 121, the two ends of each second snap ring 22 are provided with second bevels 221, and the two ends of each third snap ring 32 are provided with third bevels 321; Each first placement groove 11 is provided with two first installation inclined surfaces 15, each second placement groove 21 is provided with two second installation inclined surfaces 25, and each third placement groove 31 is provided with two third installation inclined surfaces 35. The first bevel 121, the second bevel 221, the third bevel 321, the first installation bevel 15, the second installation bevel 25 and the third installation bevel 35 are all used to facilitate the disassembly and assembly of the knife sleeve 40. It should be noted that due to the arrangement of the first installation bevel 15, the second installation bevel 25 and the third installation bevel 35, the knife sleeve 40 can smoothly enter the first placement groove 11, the second placement groove 21 and the third placement groove 31, and through the arrangement of the first bevel 121, the second bevel 221 and the third bevel 321, the first clamping ring 12, the second clamping ring 22 and the third clamping ring 32 can smoothly enter and exit the clamping groove 421, making the clamping and installation process of the knife sleeve 40 smoother, saving time and effort, and improving the processing efficiency of the product.

[0034] like Figure 1-3 As shown, the lifting assembly 60 includes a lifting cylinder 61 fixedly mounted on the rotating assembly 50, a lifting plate 62 is fixedly connected to the first cutter disc 10, and a telescopic rod of the lifting cylinder 61 passes through the third cutter disc 30, the second cutter disc 20 and the first cutter disc 10 in sequence, and is fixedly connected to the lifting plate 62; Among them, a limit hook 70 is installed at the bottom of the first cutter disc 10, and the limit hook 70 is used to limit the lifting stroke of the first cutter disc 10. In this embodiment, the limit hook 70 is set in an L shape, and the number of the limit hooks 70 can be two. The limit hook 70 is connected to the first cutter disc 10 by screws or welding; when the lifting cylinder 61 drives the first cutter disc 10 to perform a lifting movement, the limit hook 70 is hooked with the first support disc 509, and then the lifting stroke of the first cutter disc 10 can be limited to prevent the first cutter disc 10 from being lifted too much, reduce the risk of collision between the cutter disc structure and other structures of the machining center, and ensure that the machining operations of the machining center are safely and smoothly implemented.

[0035] It should be noted that the lifting cylinder 61 is fastened on the rotating shaft, and the telescopic rod is driven by the lifting cylinder 61 to perform lifting. Since the telescopic rod is fixedly connected to the lifting plate 62, and the lifting plate 62 is fixedly connected to the first tool disc 10, the lifting plate 62 drives the first tool disc 10 to perform a lifting movement, and then the tool in the tool sleeve 40 can be quickly lifted to the preset tool changing position, and the tool can be assembled to the machining spindle of the machining center through an external intelligent robot or manipulator, thereby realizing the tool changing operation of the machining center.

[0036] In the specific implementation process, the multi-layer cutter disc structure is assembled using the following method: Step S1, obtaining a pre-installed rotating assembly 50; Step S2, sequentially assembling the third cutter disc 30, the second cutter disc 20 and the first cutter disc 10 to the rotating assembly 50; Step S3, installing the lifting assembly 60 onto the rotating assembly 50; Step S4, based on the preset rotation angle and rotation direction, the first cutter disc 10, the second cutter disc 20 and the third cutter disc 30 are driven to rotate through the rotating component 50, and the tool on the cutter disc structure is moved to the preset tool change position; in the present embodiment, based on the tool position on the cutter disc structure and the preset tool change position, the rotation angle and rotation direction of the rotating shaft 502 are determined, so that the rotating shaft 502 drives the first cutter disc 10, the second cutter disc 20 and the third cutter disc 30 to rotate quickly, and the tool on the cutter disc structure is moved to the preset tool change position, and then the tool is assembled to the machining spindle of the machining center through an external intelligent robot or manipulator, thereby realizing the tool change operation of the machining center.

[0037] Step S5, based on the preset lifting distance, the first cutter disc 10 is lifted by the lifting assembly 60, so that the external tool changing manipulator can quickly pick up and place the tool on the first cutter disc 10. It should be noted that the tool on the first cutter disc 10 can be lifted to the tool taking position by driving the first cutter disc 10 to lift by the lifting assembly 60; the lifting assembly 60 can also cooperate with an external intelligent robot or manipulator, and when the external intelligent robot or manipulator grabs the tool sleeve 40, a force can be applied to the tool sleeve 40 through the telescopic effect of the lifting assembly 60, so that the clamping groove 421 of the tool sleeve 40 can be smoothly separated from the first clamping ring 12, thereby realizing rapid tool change.

[0038] Working principle: The present invention provides a multi-layer tool disc structure, in which the first tool disc 10, the second tool disc 20 and the third tool disc 30 are arranged in layers in sequence along the vertical direction downward, and the tool sleeve 40 is clamped and installed through the first placement groove 11, the second placement groove 21 and the third placement groove 31, thereby increasing the capacity of the tool; in addition, since the second placement groove 21 is staggered with the first placement groove 11 and the third placement groove 31, respectively, the multi-layer tool disc structure has a compact structure and occupies a small volume; through the rotation of the rotating component 50, the rotating shaft 502 drives the first tool disc 10, the second tool disc 20 and the third tool disc 30 to rotate, and the tool on the tool disc structure can be quickly moved to the preset tool changing position; in addition, the first tool disc 10 is driven to perform a lifting movement through the lifting component 60, and the tool on the first tool disc 10 can be lifted to the tool picking position, so that an external intelligent robot or manipulator can quickly pick up the tool.
