[0015] A management method for a machine tool tool management device for a numerically controlled machine tool comprises the following steps: The first step is to control the power motor to drive the selection device to rotate, and the selection device is used to move the clamping device inward along the inclined slide groove. When the clamping device moves to the innermost position, the tool is clamped into the inside of the clamping groove through the top for storage. Multiple tools are installed in different clamping grooves respectively according to the same method; The second step is that when you need to select a tool during use, control the power motor to rotate clockwise, the power motor drives the rotating disk to rotate clockwise, the rotating disk drives the limit push plate to rotate clockwise, and the limit push plate will deflect inward and pass over the support sleeve after contacting the support sleeve. When the limit push plate passes over the support sleeve under the tool to be taken out, the selection work is completed; The third step is to control the power motor to rotate counterclockwise when the tool needs to be sent out. At this time, after the limit push plate contacts the support sleeve, the limit push plate remains in an inclined state under the support of the support column, and the limit push plate pushes the support sleeve to apply a force moving inward, and the support sleeve moves inward along the surface of the limit push plate until it moves to the inner side of the support arc frame and is supported by being clamped. During the movement of the support sleeve, the plug-in rod is driven to move inward, and the plug-in rod moves inward under the restriction of the transverse sliding seat and the transverse limit sliding groove. When the plug-in rod moves inward, it drives the support seat to move inward, and the support seat will also move upward during the process of moving inward under the restriction of the side sliding block and the inclined sliding groove, thereby driving the clamping cylinder seat to move inward and upward through the support seat, so that the tool is lifted upward through the top opening of the storage box; The fourth step is to insert the used tool into the clamping groove from the top. The tool is inserted into the clamping groove to squeeze the clamping block to move outward and compress the clamping spring, so that the tool is clamped and fixed through the cooperation of the clamping spring and the clamping block, and then the rotating disk is controlled to continue to rotate counterclockwise. The rotating disk drives the support arc frame to rotate so that the support sleeve is separated from the support of the support arc frame. After the support sleeve moves to the surface of the extended inclined plate, the tension spring applies a pulling force to the plug rod and the support seat to approach each other. The support seat will move outward under the restriction of the inclined slide groove. The support seat is close to the lower end. With the cooperation of the plug rod, the support sleeve and the extended inclined plate, the support sleeve slowly moves outward along the surface of the extended inclined plate to improve the running stability, thereby realizing the function of tool recovery and storage. The fifth step is that during the process of the support seat moving outward along the inclined slide groove, the support seat drives the gear ring to move outward through the clamping cylinder seat, and the gear ring drives the clamping cylinder seat to rotate under the restriction of the tooth row, and the clamping cylinder seat drives the tool clamped inside it to rotate, and the tool contacts and rotates with the cleaning strip, so that the surface of the tool is brushed and cleaned by the cleaning strip, and the tool moves outward and downward at the same time, so that the cleaning strip wipes more evenly, and at the same time, the debris wiped by the cleaning strip approaches the surface of the side panel under the support of the cleaning strip, and then falls into the inside of the guide box, and finally slides outward along the inside of the guide box and falls into the collection box for storage, thereby completing the removal, storage and cleaning of the tool.

[0016] (III) Beneficial effects The present invention provides a tool management device and method for a CNC machine tool, which has the following beneficial effects: 1. By setting up a cleaning device, the tool surface can be automatically wiped and cleaned during the process of pushing out and retracting the tool, thereby preventing debris from adhering to the tool surface and affecting the life of the tool and the accuracy of subsequent processing. The cleaned debris will be automatically collected along the guide box to the inside of the collection box for easy cleaning.

[0017] 2. By setting up the coordination of the clamping device and the picking device, the clamping device is pushed from the outside to the inside through the picking device. When taking out, the tools stored at different angles will be pushed upward through the center position, so as to facilitate the picking of the tools and the clamping of the CNC machine tools, and facilitate the installation and storage of tools in fixed positions of the CNC machine tools, which is easy to use.

[0018] 3. Through the cooperation of the power motor and the selecting device, the tool selection work can be achieved by controlling the power motor to rotate clockwise, and the tool pushing work can be achieved by controlling the power motor to rotate counterclockwise. When tools in different orientations are needed, first control the power motor to drive the selecting device to rotate clockwise to the corresponding angle position, and then control the power motor to drive the selecting device to rotate counterclockwise to push out the selected tool, thereby reducing the difficulty of the selecting operation.

[0019] 4. When installing the tools, they can be installed in sequence according to the order in which they are used, so that the tools can be quickly and sequentially installed during processing to improve processing efficiency. BRIEF DESCRIPTION OF THE DRAWINGS

The power motor 5 is a stepping motor, which can accurately control The angle of rotation is controlled by numerical control of the rotation angle of the power motor 5. When tools in different orientations are needed, the power motor 5 is first controlled to drive the selection device 6 to rotate clockwise to the corresponding angle position, and then the power motor 5 is controlled to drive the selection device 6 to rotate counterclockwise to push out the selected tool. The data of the tool model stored in the position corresponding to the rotation angle of the power motor 5 is uploaded in advance. When a specified model of tool is needed, the selection device 6 can be quickly controlled by numerical control to rotate clockwise to a specified degree to complete the selection, and then rotate counterclockwise to push out the tool.

[0027] As attached Figure 2 , Figure 5 and Figure 6As shown, the cleaning device 7 includes a toothed ring 71, a side plate 72, a tooth row 73, a guide box 74, a cleaning strip 75 and a collecting box 76. The toothed ring 71 is installed on the outer wall of the clamping cylinder seat 43, the side plate 72 is installed on the inner wall of the storage box 1, the toothed row 73 is installed on the surface of the side plate 72 near the bottom, the guide box 74 is installed on the surface of the side plate 72 and is located above the toothed row 73, the cleaning strip 75 is installed on the surface of the side plate 72 and is located above the guide box 74, and the cleaning strip 75 is used to clean the surface of the tool. Engaged with the tooth row 73, the tooth row 73 is relatively high, and the tooth ring 71 also moves vertically while moving horizontally, so that the tooth ring 71 can maintain the meshing state with the tooth row 73, and the collection box 76 is installed with the outer wall of the storage box 1 through a thread. When the collection box 76 needs to be cleaned, the collection box 76 can be removed from the top of the storage box 1 by rotating the collection box 76. The surface of the storage box 1 and the inner side of the guide box 74 are provided with a chip removal hole. The debris inside the guide box 74 is discharged into the collection box 76 through the chip removal hole for storage.

[0028] As attached Figure 5 As shown, the clamping groove 46 is divided into two cavities, the top opening of the upper cavity is larger than the opening of the lower cavity. The larger opening at the top of the clamping groove 46 is convenient for alignment, and the smaller opening at the lower side can reduce the error after storage and installation. After the tool is inserted into the smaller cavity at the lower side, it is clamped and fixed by the cooperation of the clamping spring 44 and the clamping block 45 on the outside.

[0029] As attached Figure 2 and Figure 3 As shown, the mounting seat 3 is conical, the inclined groove 31 is opened at an angle, an inclined section is opened at the bottom of the support seat 41, and the bottom end of the support seat 41 is inserted into the inclined groove 31 through the side slider 42, so that the support seat 41 can move vertically while moving radially, so that the tool can be pushed upward. The clamping springs 44 and the clamping blocks 45 are four in a group, and the tool is clamped and fixed by the cooperation of the four clamping springs 44 and the clamping blocks 45.

[0030] As attached Figure 7As shown, the limit push plate 62 is installed at an angle, and the outer end of the extended inclined plate 65 extends to the inner side of the support sleeve 69, and the outer end of the limit push plate 62 extends to the outer side of the support sleeve 69. When the limit push plate 62 rotates clockwise and contacts the support sleeve 69, the limit push plate 62 will rotate along the installation axis pin position at the bottom to pass over the support sleeve 69. When the limit push plate 62 rotates counterclockwise, the limit push plate 62 will not deflect under the obstruction of the support column 63, thereby pushing the support sleeve 69 to move inward. The extended inclined plate 65 is shorter and can directly pass over the support sleeve 69 on the outside during the rotation process without hindering the rotation. The extended inclined plate 65 is used to support the support sleeve 69 moving outward to prevent the support sleeve 69 from moving outward too fast and affecting the storage stability.

[0031] As attached Figure 5 As shown, the cleaning strip 75 is tilted upward on the side away from the side panel 72, so that the debris swept by the cleaning strip 75 will move along the surface of the cleaning strip 75 to a position close to the surface of the side panel 72, reducing the amount of debris that directly falls into the inclined chute 31. A notch is provided at the position close to the side panel 72. After the debris moves over the cleaning strip 75 to a position close to the side panel 72, it falls downward through the notch into the guide box 74, thereby reducing the frequency of maintenance. The outer end of the bottom of the guide box 74 is tilted downward, and the debris that falls into the guide box 74 will be gathered and then move outward to enter the collection box 76 for storage.

[0032] A management method for a machine tool tool management device for a numerically controlled machine tool comprises the following steps: In the first step, the power motor 5 is controlled to drive the selection device 6 to rotate, and the clamping device 4 is moved inward along the inclined slide groove 31 by the selection device 6. When the clamping device 4 moves to the innermost position, the tool is clamped into the inside of the clamping groove 46 through the top for storage. According to the same method, multiple tools are respectively installed in different clamping grooves 46; In the second step, when it is necessary to select a tool during use, the power motor 5 is controlled to rotate clockwise, the power motor 5 drives the rotating disk 61 to rotate clockwise, the rotating disk 61 drives the limit push plate 62 to rotate clockwise, and the limit push plate 62 will deflect inward and pass over the support sleeve 69 after contacting the support sleeve 69. When the limit push plate 62 passes over the support sleeve 69 under the tool to be taken out, the selection work is completed; In the third step, when the tool needs to be sent out, the power motor 5 is controlled to rotate counterclockwise. At this time, after the limit push plate 62 contacts the support sleeve 69, the limit push plate 62 remains in an inclined state under the support of the support column 63, and the limit push plate 62 pushes the support sleeve 69 to apply a force moving inward, and the support sleeve 69 moves inward along the surface of the limit push plate 62 until it moves to the inner side of the support arc frame 64 and is supported by being clamped. During the movement of the support sleeve 69, the plug-in rod 66 is driven to move inward, and the plug-in rod 66 moves inward under the restriction of the transverse sliding seat 68 and the transverse limiting groove 33. When the plug-in rod 66 moves inward, it drives the support seat 41 to move inward. The support seat 41 will also move upward during the process of moving inward under the restriction of the side sliding block 42 and the inclined groove 31, thereby driving the clamping cylinder seat 43 to move inward and upward through the support seat 41, so that the tool is lifted upward through the top opening of the storage box 1; The fourth step is to insert the used tool into the clamping groove 46 from the top. The tool is inserted into the clamping groove 46 to squeeze the clamping block 45 and move it outward to compress the clamping spring 44, so that the tool is clamped and fixed by the cooperation of the clamping spring 44 and the clamping block 45, and then the rotating disk 61 is controlled to continue to rotate counterclockwise, and the rotating disk 61 drives the support arc frame 64 to rotate so that the support sleeve 69 is separated from the support of the support arc frame 64. After the support sleeve 69 moves to the surface of the extended inclined plate 65, the tension spring 67 applies a pulling force to the plug rod 66 and the support seat 41 to approach each other. The support seat 41 will move outward under the restriction of the inclined slide groove 31. The support seat 41 is close to the lower end. Under the cooperation of the plug rod 66, the support sleeve 69 and the extended inclined plate 65, the support sleeve 69 moves slowly outward along the surface of the extended inclined plate 65, thereby improving the operation stability effect, thereby realizing the function of tool recovery and storage. The fifth step is that during the process of the support seat 41 moving outward along the inclined slide groove 31, the support seat 41 drives the gear ring 71 to move outward through the clamping cylinder seat 43, and the gear ring 71 drives the clamping cylinder seat 43 to rotate under the restriction of the tooth row 73, and the clamping cylinder seat 43 drives the tool clamped inside it to rotate, and the tool contacts and rotates with the cleaning strip 75, so that the surface of the tool is brushed and cleaned by the cleaning strip 75, and the tool moves outward and downward at the same time, so that the cleaning strip 75 wipes more evenly. At the same time, the debris wiped by the cleaning strip 75 approaches the surface of the side plate 72 under the support of the cleaning strip 75, and then falls into the inside of the guide box 74, and finally slides outward along the inside of the guide box 74 and falls into the collection box 76 for storage, thereby completing the removal, storage and cleaning of the tool.

[0033] The working principle and use process of the present invention are as follows: the device is installed above the workbench by the cooperation of the bolts and the mounting chassis 2. When the tool needs to be taken out, the power motor 5 is controlled to rotate clockwise, and the power motor 5 drives the limit push plate 62 to rotate clockwise to the clockwise side below the corresponding tool, and then the power motor 5 rotates counterclockwise, and the power motor 5 drives the rotating disk 61 to rotate counterclockwise, and the rotating disk 61 drives the limit push plate 62 to rotate counterclockwise. The limit push plate 62 pushes the support sleeve 69 to move inward under the support of the support column 63, and the support sleeve 69 moves to the inner side of the support arc frame 64 under the push of the limit push plate 62, and the power motor 5 The rotation stops, and the support sleeve 69 moves inwardly, while the support seat 41 is driven to move inwardly along the inclined slide groove 31 through the plug-in rod 66. The support seat 41 drives the clamping cylinder seat 43 to move inwardly and upwardly at the same time. The clamping cylinder seat 43 drives the tool clamped at its top to push open the fan-shaped top cover plate 8 and extend it through the top opening of the storage box 1, so that the ejected tool can be clamped and installed for use. After use, the tool is reinserted into the clamping cylinder seat 43, and the tool is fixed in the clamping cylinder seat 43 through the cooperation of the clamping spring 44 and the clamping block 45. Then the power motor 5 continues to rotate counterclockwise, and the rotating disk 6 1 drives the support arc frame 64 and the extension inclined plate 65 to rotate, so that the support sleeve 69 is separated from the support arc frame 64 and moves to the inner side of the extension inclined plate 65. At this time, the tension spring 67 applies a pulling force to the plug rod 66 and the support seat 41 to approach each other. The support seat 41 will move outward under the restriction of the inclined slide groove 31. The lower end of the support seat 41, under the cooperation of the plug rod 66, the support sleeve 69 and the extension inclined plate 65, the support sleeve 69 moves slowly outward along the surface of the extension inclined plate 65, so that the support seat 41 moves slowly outward along the inclined slide groove 31. At the same time, the support seat 41 drives the gear ring 71 to move outward through the clamping cylinder seat 43, and the gear ring 71 moves outward. After moving to the inner side of the tooth row 73, the tooth ring 71 drives the clamping cylinder seat 43 to rotate under the restriction of the tooth row 73, and the clamping cylinder seat 43 drives the tool clamped inside thereof to rotate, and the tool contacts the cleaning strip 75 and rotates, so that the surface of the tool is brushed and cleaned by the cleaning strip 75, and the tool moves outward and downward at the same time, so that the cleaning strip 75 wipes more evenly and improves the wiping coverage. At the same time, the debris wiped by the cleaning strip 75 approaches the surface of the side plate 72 under the support of the cleaning strip 75, and then falls into the inside of the guide box 74, and finally slides outward along the inside of the guide box 74 and falls into the inside of the collection box 76 for storage.

10. A management method for a machine tool management device for a numerically controlled machine tool, comprising a machine tool management device for a numerically controlled machine tool according to any one of claims 1 to 9, characterized in that: The following steps are involved: The first step is to control the power motor (5) to drive the selection device (6) to rotate, and the selection device (6) drives the clamping device (4) to move inward along the inclined slide groove (31). When the clamping device (4) moves to the innermost position, the tool is clamped into the inside of the clamping groove (46) through the top for storage. According to the same method, multiple tools are respectively installed in different clamping grooves (46); In the second step, when it is necessary to select a tool during use, the power motor (5) is controlled to rotate clockwise, the power motor (5) drives the rotating disk (61) to rotate clockwise, the rotating disk (61) drives the limit push plate (62) to rotate clockwise, and the limit push plate (62) deflects inward and passes over the support sleeve (69) after contacting the support sleeve (69). When the limit push plate (62) passes over the support sleeve (69) below the tool to be taken out, the selection work is completed; In the third step, when the tool needs to be sent out, the power motor (5) is controlled to rotate counterclockwise. At this time, after the limit push plate (62) contacts the support sleeve (69), the limit push plate (62) remains in an inclined state under the support of the support column (63). The limit push plate (62) pushes the support sleeve (69) to apply a force moving inward, and the support sleeve (69) moves inward along the surface of the limit push plate (62) until it moves to the inner side of the support arc frame (64) and is supported by the clamping. During the movement of the support sleeve (69), the plug-in The rod (66) moves inwardly, and the plug-in rod (66) moves inwardly under the restriction of the transverse slide seat (68) and the transverse limit slide groove (33). When the plug-in rod (66) moves inwardly, it drives the support seat (41) to move inwardly. The support seat (41) also moves upwardly during the process of moving inwardly under the restriction of the side slide block (42) and the inclined slide groove (31), thereby driving the clamping cylinder seat (43) to move inwardly and upwardly through the support seat (41), so that the tool is lifted upward through the top opening of the storage box (1); In the fourth step, the used tool is inserted from the top into the inside of the clamping groove (46). The tool is inserted into the clamping groove (46) to squeeze the clamping block (45) to move outward and compress the clamping spring (44), so that the tool is clamped and fixed by the cooperation of the clamping spring (44) and the clamping block (45). Then, the rotating disk (61) is controlled to continue to rotate counterclockwise, and the rotating disk (61) drives the support arc frame (64) to rotate so that the support sleeve (69) is separated from the support of the support arc frame (64). The support sleeve (69 ) moves to the surface of the extended inclined plate (65), the tension spring (67) applies a pulling force to the plug rod (66) and the support seat (41) to move closer to each other, and the support seat (41) moves outward under the restriction of the inclined slide groove (31). The lower end of the support seat (41) cooperates with the plug rod (66), the support sleeve (69) and the extended inclined plate (65), and the support sleeve (69) moves slowly outward along the surface of the extended inclined plate (65), thereby improving the running stability effect, thereby realizing the function of tool recovery and storage; In the fifth step, when the support seat (41) moves outward along the inclined slide groove (31), the support seat (41) drives the toothed ring (71) to move outward through the clamping cylinder seat (43). The toothed ring (71) drives the clamping cylinder seat (43) to rotate under the restriction of the tooth row (73). The clamping cylinder seat (43) drives the tool clamped inside thereof to rotate. The tool contacts the cleaning strip (75) and rotates, so that the cleaning strip (75) brushes the surface of the tool to clean it. The tool moves outward and downward at the same time, so that the cleaning strip (75) wipes more evenly. At the same time, the debris wiped by the cleaning strip (75) approaches the surface of the side plate (72) under the support of the cleaning strip (75), and then falls into the inside of the guide box (74), and finally slides outward along the inside of the guide box (74) and falls into the inside of the collection box (76) for storage, thereby completing the removal, storage and cleaning of the tool.
