Description

Technical Field

[0001] This utility model relates to the field of machine tool magazine technology, and in particular to a tool magazine structure for storing cutting tools in CNC machine tools. Background Technology

[0002] Tool magazines, used for storing and automatically changing cutting tools in CNC machine tools, ensure efficient tool utilization and precise operation. Common tool magazines include disc-type, chain-type, and manual tool magazines. Existing disc-type tool magazines are typically disc-shaped, with tool slots arranged in a ring around the edge of the magazine. The disc is rotated by a motor, and when changing tools, the disc rotates to the desired tool position. However, when tools are stored in the tool slots after use, the surface of the tools often accumulates machining waste and dust. Current devices cannot automatically clean the tools in the tool slots, meaning that after prolonged use, the accumulated impurities on the tool surface may negatively impact subsequent turning operations. This not only affects the cutting performance of the tool but may also reduce machining accuracy and surface quality.

[0003] The purpose of this utility model is to provide a tool magazine structure for storing cutting tools in CNC machine tools, so as to solve the problems mentioned in the background art. Utility Model Content

[0004] The purpose of this utility model is to address the shortcomings of the existing technology mentioned in the background section by proposing a tool magazine structure for storing cutting tools in CNC machine tools.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A tool magazine structure for storing cutting tools in a CNC machine tool includes a tool magazine body, a tool slot, and an air outlet. The tool slot is fitted inside the tool magazine body, and the air outlet is fitted inside the tool slot. A main air duct is fitted to the rear end of the tool magazine body, and a fan is fitted to the outer side of the main air duct. A dust collection trough is provided outside the fan, and an air outlet duct is connected through the inner side of the dust collection trough. One end of the air outlet duct is fitted with a dust discharge port, and the other end of the air outlet duct passes through the tool magazine body and is connected through the tool slot. An air duct is connected through the outer side of the main air duct, and a connecting pipe is connected through the other end of the air duct. The other end of the connecting pipe passes through the tool slot and is connected through the air outlet.

[0007] Preferably, the inner side of the dust discharge port is fitted with a dust outlet flat opening, and the outer side of the dust outlet flat opening is provided with a return groove located inside the dust discharge port.

[0008] Preferably, air jets are fitted and connected to both sides of the inner side of the tool groove, and the air jets are hemispherical in shape. Air jet holes are provided on the surface of the air jets near the inner side of the tool groove and the surface near the air outlet pipe.

[0009] Preferably, the dust outlet flat nozzle is located at the inner center of the dust discharge port, and the output end of the dust outlet flat nozzle is flat.

[0010] Preferably, the main air duct is located at the center of the back of the main body of the tool magazine, and a one-way air valve is provided at the connection between the main air duct and the air duct.

[0011] Preferably, connecting plates are fitted and connected to both the left and right sides of the dust collection trough, and the other end of the connecting plate is fixedly connected to the main body of the tool magazine.

[0012] Preferably, the dust collection trough is circular in shape, and the surface of the dust collection trough is provided with a circular cover.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0014] 1. In this utility model, by setting up an air jet nozzle and a fan, after the tool is replaced, the tool is placed in the tool slot, and the fan can guide the air force to the air jet nozzle through the air duct for output. In this way, the air jet nozzle inside the tool slot can effectively output air force to clean the impurities remaining on the tool surface, thereby avoiding the adhesion of a large amount of waste residue and dust generated by turning after long-term use. This design helps to maintain the cleanliness and performance of the tool, and ensures the cutting effect and machining accuracy of the tool in subsequent processing.

[0015] 2. By setting up a dust collection trough and a dust outlet flat nozzle, the impurities blown off by this device can be guided through the air outlet pipe to the dust outlet flat nozzle and discharged into the dust collection trough, preventing the blown-off impurities from falling around the device and affecting the lathe. At the same time, the output end of the dust outlet flat nozzle adopts a flat design. This structure effectively reduces the possibility of impurities and dust flowing back into the dust outlet flat nozzle from the output outlet. Since there is a return groove on the outside of the dust outlet flat nozzle, this structure effectively reduces the possibility of impurities and dust flowing back into the dust outlet flat nozzle from the output outlet.

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0027] Example

[0028] Reference Figure 1-6A tool magazine structure for storing cutting tools in CNC machine tools includes a tool magazine body 1, a tool slot 2, and an air vent 3. The tool magazine body 1 is a disc-shaped tool magazine, and a rotating motor is provided on the inner side of the tool magazine body 1. A drive shaft is provided on the outer side of the motor, and the other end of the drive shaft is connected to a turntable. The tool slot 2 is fitted and connected to the outer side of the turntable. When the machine tool needs to change tools, the rotating motor can drive the turntable to rotate through the drive shaft, which in turn drives the tool slot 2 to rotate until the tool slot 2 is aligned with the tool changing robot arm, so that the robot arm can grasp and change the tool.

[0029] The tool magazine body 1 has a tool slot 2 fitted inside, and an air jet 3 fitted inside the tool slot 2. A main air duct 9 is fitted to the rear end of the tool magazine body 1, and a fan 4 is fitted to the outer side of the main air duct 9. A dust collection trough 5 is provided on the outer side of the fan 4, and an air outlet duct 6 is connected through the inner side of the dust collection trough 5. One end of the air outlet duct 6 is fitted with a dust discharge port 7, and the other end of the air outlet duct 6 passes through the tool magazine body 1 and is connected to the tool slot 2. An air duct 8 is connected through the outer side of the main air duct 9, and a connecting pipe 12 is connected through the other end of the air duct 8. The other end of the connecting pipe 12 passes through the tool groove 2 and is connected to the air jet 3. Through this design, the fan 4 can output air through the main air pipe 9, and then guide the output air through the air pipe 8 and the connecting pipe 12 to the air jet 3, thereby circulating the air inside the tool groove 2. In this way, the air jet 3 can effectively blow the impurities and dust on the surface of the tool stored inside the tool groove 2 into the dust collection tank 5 for collection, thereby avoiding the adhesion of a large amount of impurities and dust generated by turning on the surface of the tool after long-term use, and maintaining the cleanliness and performance of the tool.

[0030] It should be noted that the main air duct 9 is divided into two pipe sections, which are connected by a rotatable connecting pipe. In this way, when the turntable inside the tool magazine body 1 rotates by the rotating motor, the air outlet pipe 6, the air duct 8 connected to the tool slot 2 and the pipe section near the tool magazine body 1 can rotate synchronously, avoiding the connection of the air jet 3, the connecting pipe 12 and the air duct 8 from affecting the normal use of the tool magazine body 1.

[0031] The dust outlet 7 is fitted with a dust outlet flat port 10 on its inner side, and a return groove 11 is provided on the outer side of the dust outlet flat port 10 located inside the dust outlet 7. This allows dust blown off the tool surface to be output through the dust outlet flat port 10 to the interior of the dust collection groove 5. Since the dust outlet flat port 10 is located at the center of the inner side of the dust outlet 7 and the output end of the dust outlet flat port 7 adopts a flat design, this structure effectively reduces the possibility of impurities and dust flowing back from the output port of the dust outlet flat port 10 into the interior of the dust outlet flat port 10. Because the dust outlet flat port 10 has a return groove 11 on its outer side, this structure effectively reduces the possibility of impurities and dust flowing back from the output port of the dust outlet flat port 10 into the interior of the dust outlet flat port 10. This design also allows some impurities and dust remaining on the outer side of the dust outlet flat port 10 to smoothly enter the interior of the return groove 11, further reducing the risk of impurities and dust flowing back into the dust outlet flat port 10, thereby improving the cleanliness and stability of the system.

[0032] Both sides of the tool groove 2 are fitted with air nozzles 3, and the air nozzles 3 are hemispherical in shape. Air holes are opened on the surface of the air nozzles 3 on the side near the inside of the tool groove 2 and the side near the air outlet pipe 6. Through this design, the air nozzles 3 can output air force from different angles to clean the tool, thereby improving the efficiency of the air nozzles 3 in cleaning the tool.

[0033] The main air duct 9 is located at the center of the back of the main body 1 of the tool magazine, and one-way air valves are provided at the connection between the main air duct 9 and the air duct 8. This design can prevent the air inside the air duct 8 from flowing back into the main air duct 9.

[0034] The dust collection trough 5 is fitted with connecting plates on both the left and right sides, and the other end of the connecting plates is fixedly connected to the tool magazine body 1. The dust collection trough 5 is circular in shape, and the surface of the dust collection trough 5 is provided with a circular cover. Through this design, the dust collection trough 5 is installed on one side of the tool magazine body 1 through the connecting plates. When the staff needs to clean the dust accumulated inside the dust collection trough 5, the staff can unscrew the fixing bolts on the surface of the cover and then remove the cover to clean the impurities and dust collected inside the dust collection trough 5.

[0035] Working principle: When the machine tool needs to change tools, the rotating motor drives the turntable to rotate via the transmission shaft, which in turn drives the tool slot 2 to rotate until the tool slot 2 is aligned with the tool changing robot arm, so that the robot arm can grasp and change the tool. When it is necessary to clean the tools stored in the tool slot 2, the operator can start the fan 4 through the external controller, so that the fan 4 can output air through the main air duct 9, and then guide the output air through the air duct 8 and the connecting pipe 12 to the air jet vent 3, so as to circulate the air inside the tool slot 2. In this way, the air jet vent 3 can effectively blow the impurities and dust on the surface of the tools stored in the tool slot 2 into the dust collection tank 5 for collection, thereby avoiding the adhesion of a large amount of impurities and dust generated by turning after long-term use, and maintaining the cleanliness and performance of the tools.

[0036] The above embodiments are preferred embodiments of the present utility model, but the embodiments of the present utility model are not limited to the above embodiments. Any changes, modifications, substitutions, combinations, or simplifications made without departing from the spirit and principle of the present utility model shall be considered equivalent substitutions and shall be included within the protection scope of the present utility model.

[0037] In the description of this utility model, it should be understood that the terms indicating orientation or positional relationship are based on the orientation or positional relationship shown in the drawings and are only for the convenience of describing this utility model and simplifying the description, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model.
