Description

Technical Field

[0001] This application relates to the field of tool switching technology, and in particular to an automatic tool switching device for high-precision component machining. Background Technology

[0002] In the field of high-precision component machining, the performance of cutting tools directly affects machining efficiency and product quality. With the development of industrial automation technology, the automation level of machine tools is constantly improving, placing higher demands on the automatic tool changing process. Automatic tool changers, as one of the key technologies for improving production efficiency and machining accuracy, have been widely used in CNC machine tools. These devices can seamlessly coordinate the tool changing process, achieving uninterrupted machining, reducing human intervention, and improving productivity.

[0003] Currently, CNC automatic tool changers employ various tool changing methods, including umbrella-type tool magazines, dual-arm tool magazines, robotic tool changers, rotary tool magazines, and random access tool changers. These systems achieve rapid and precise tool changes through different mechanical structures and control strategies. For example, dual-arm tool magazines reduce tool change time by performing tool changing operations simultaneously with two arms. Robotic tool changers utilize grippers or tool changing mechanisms on robotic arms to grasp and change tools. Furthermore, there are PLC-based automatic tool changer control systems that improve the accuracy of tool selection and positioning, shorten changeover time, and reduce operational errors by optimizing control logic.

[0004] Although existing technologies have made some progress in automatic tool changing, in actual production processes, due to factors such as machine tool inherent errors, tool wear, and thermal deformation, the machined parts often have certain errors. Regular tool replacement to reduce the impact of tool wear on part machining is necessary. However, during machining, chips easily adhere to the tool surface, causing existing tool magazines to collect chips along with the still-warm tool during tool changes. During tool transfer, prolonged thermal deformation of the tool combined with friction between the tool and chips accelerates tool wear and damage, affecting tool accuracy. Utility Model Content

[0005] The purpose of this application is to address the problem that when changing tools in existing tool magazines, debris and tools that have not yet fully cooled down are easily collected into the tool magazine at the same time. This causes the tool to deform due to heat over a long period of time, and the friction between the tool and the debris accelerates the wear and damage of the tool, affecting the accuracy of the tool. This application provides an automatic tool switching device for machining high-precision components.

[0006] To achieve the above objectives, this application specifically adopts the following technical solution:

[0007] An automatic tool switching device for high-precision component machining includes a tool magazine body. A hexagonal base is rotatably connected inside the tool magazine body. Guide rods are symmetrically fixed to the hexagonal ends of the hexagonal base. An arc-shaped clamping plate is slidably connected to one end of each guide rod. A refrigeration compressor is fixedly connected to the top of the tool magazine body. An air pump is fixedly connected to the output end of the refrigeration compressor via a pipe. A nozzle is fixedly connected to the output end of the air pump via a pipe. The output end of the nozzle extends to the inner top of the tool magazine body. A vibration rod is rotatably connected inside the tool magazine body. A drive assembly for driving the hexagonal base to rotate is installed inside the tool magazine body. Fixed assemblies for driving the arc-shaped clamping plate to move along the length of the guide rods are installed at the hexagonal ends of the hexagonal base. A vibration mechanism for driving the vibration rod to vibrate the hexagonal base is installed inside the tool magazine body.

[0008] By adopting the above technical solution, and by setting up the coordinated use of the drive component, the fixing component, and the vibration mechanism, it is easy to drive the two arc-shaped clamping plates to move closer to each other along the length of the guide slide rod by activating the fixing component, thereby achieving rapid clamping and fixing of the tool. Then, when the drive component drives the hexagonal support to move the tool to below the nozzle, the refrigeration compressor and air pump are activated to output cold air to the surface of the tool to assist in cooling the tool and blow off the debris adhering to the surface of the tool. This facilitates rapid cooling and debris removal of the tool, reduces wear caused by long-term tool thermal deformation and friction between the tool and debris, and improves the precision of the tool.

[0009] Furthermore, the drive assembly includes a drive worm gear fixedly connected to one end of the hexagonal base, a drive worm wheel rotatably connected to the inner top of the tool magazine body and meshing with the drive worm gear, a drive motor fixedly connected to the inner top of the tool magazine body, and the output end of the drive motor fixedly connected to the drive worm gear.

[0010] By adopting the above technical solution and setting the driving worm and driving worm wheel to work together, the starting drive motor can drive the driving worm wheel to mesh with the driving worm, and the driving worm can drive the hexagonal bearing to rotate, which effectively improves the practicality of the device.

[0011] Furthermore, the fixing component includes a guide groove formed at one end of the hexagonal base, a U-shaped slide rod slidably connected inside the guide groove, a fixed electric actuator fixedly connected to one end of the hexagonal base, the output end of the fixed electric actuator fixedly connected to the U-shaped slide rod, a fixed inclined rod adapted to the U-shaped slide rod fixedly connected to one end of the arc-shaped clamping plate, and a return spring fixedly connected to one end of the arc-shaped clamping plate, the return spring being sleeved on one end of the guide slide rod.

[0012] By adopting the above technical solution, and through the coordinated use of the U-shaped slide bar and the fixed inclined bar, the activation of the fixed electric actuator can push the U-shaped slide bar to move along the length of the guide groove, causing the U-shaped slide bar and the fixed inclined bar to slide against each other. This, in turn, pushes the fixed inclined bar to move the two arc-shaped clamps closer together along the length of the guide slide bar. Conversely, when the fixed electric actuator is activated in the opposite direction, the return spring's rebound characteristic causes the return spring to rebound and push out the arc-shaped clamps, pushing the two arc-shaped clamps further away from each other along the length of the guide slide bar, thus further improving the practicality of the device.

[0013] Furthermore, the vibration mechanism includes a vibrating rubber block fixedly connected to the bottom of the tool magazine body. One end of the vibrating rod passes through the tool magazine body and extends into the interior of the vibrating rubber block. An eccentric block is fixedly connected to one end of the vibrating rod. A buffer rubber ring is sleeved on the hinge end of the vibrating rod and the tool magazine body. The buffer rubber ring is fixedly connected to the tool magazine body. A rotating assembly for driving the vibrating rod to rotate is installed inside the tool magazine body.

[0014] By adopting the above technical solution, and by setting up the rotating component in conjunction with the eccentric block and the vibrating rubber block, it is convenient to drive the eccentric block to rotate eccentrically when the rotating component is started to drive the vibrating rod to rotate. This causes the eccentric block to drive the vibrating rod to generate rotational vibration, and one end of the vibrating rod transmits the vibration to the hexagonal base through the vibrating rubber block. This causes the hexagonal base to drive the arc-shaped clamping plate and the cutting tool to vibrate, thereby causing the debris adhering to the surface of the cutting tool to detach quickly, effectively improving the practicality of the device.

[0015] Furthermore, the rotating assembly includes a vibrating worm gear rotatably connected to the bottom of the tool magazine body, a traction rubber ring fixedly connected inside the vibrating worm gear, the traction rubber ring being fixedly connected to a vibrating rod, a vibrating worm gear meshing with the vibrating worm gear being rotatably connected to the bottom of the tool magazine body, a vibrating motor being fixedly connected to the bottom of the tool magazine body, and the output end of the vibrating motor being fixedly connected to the vibrating worm gear.

[0016] By adopting the above technical solution, and by setting up the cooperation of the vibrating worm, the vibrating worm wheel, and the traction rubber ring, it is convenient to start the vibrating motor to drive the vibrating worm wheel to mesh with the vibrating worm, and make the vibrating worm drive the traction rubber ring to pull the vibrating rod to rotate. By utilizing the elastic characteristics of the traction rubber ring, part of the vibration transmitted by the vibrating rod is absorbed, maintaining the stable output of the vibrating motor, and further improving the practicality of the device.

[0017] Furthermore, one end of the U-shaped slide bar is symmetrically rotatably connected to an abutting roller, which rolls and abuts against the fixed inclined bar.

[0018] By adopting the above technical solution, and by setting up the cooperation between the contact roller and the fixed inclined rod, the U-shaped slide rod forms a rolling contact with the fixed inclined rod through the contact roller, which effectively reduces the wear between the U-shaped slide rod and the fixed inclined rod and extends the service life of the device.

[0019] Furthermore, a rubber gasket is fixedly connected to the inner side of the arc-shaped clamp.

[0020] By adopting the above technical solution, and by setting up the use of rubber gaskets and arc-shaped clamps, the arc-shaped clamps form flexible contact with the cutting tool through the rubber gaskets, which effectively reduces the wear between the arc-shaped clamps and the cutting tool.

[0021] Furthermore, one end is symmetrically fixedly connected with an arc-shaped extended edge.

[0022] By adopting the above technical solution, and by setting up the arc-shaped extension edge and the arc-shaped clamping plate in combination, the contact area between the arc-shaped clamping plate and the cutting tool is effectively increased, thereby improving the clamping stability of the arc-shaped clamping plate for the cutting tool.

[0023] In summary, this application includes at least one of the following beneficial effects:

[0024] 1. By setting up the driving component, fixing component, and vibration mechanism for coordinated use, it is easy to drive the two arc-shaped clamping plates to move closer to each other along the length of the guide slide rod by activating the fixing component, thereby achieving rapid clamping and fixing of the tool. Then, when the driving component drives the hexagonal base to move the tool to below the nozzle, the refrigeration compressor and air pump are activated to output cold air to the surface of the tool to assist in cooling the tool and blow off the debris adhering to the tool surface. This facilitates rapid cooling and debris removal of the tool, reduces wear caused by prolonged tool thermal deformation and friction between the tool and debris, and improves the tool's accuracy.

[0025] 2. By setting up the rotating component in conjunction with the eccentric block and the vibrating rubber block, it is convenient to drive the eccentric block to rotate eccentrically when the rotating component is started to drive the vibrating rod to rotate. This causes the eccentric block to drive the vibrating rod to generate rotational vibration, and one end of the vibrating rod transmits the vibration to the hexagonal base through the vibrating rubber block. This causes the hexagonal base to drive the arc-shaped clamping plate and the cutting tool to vibrate, thereby quickly removing the debris adhering to the surface of the cutting tool and effectively improving the practicality of the device.

[0032] The following is in conjunction with the appendix Figure 1 —4 provides further detailed description of this application.

[0033] This application discloses an automatic tool switching device for high-precision component machining.

[0034] Reference Figure 1 - Figure 3 An automatic tool switching device for high-precision component machining includes a tool magazine body 1. A hexagonal base 2 is rotatably connected inside the tool magazine body 1. Guide slide rods 3 are symmetrically fixedly connected to the hexagonal ends of the hexagonal base 2. An arc-shaped clamping plate 4 is slidably connected to one end of the guide slide rod 3. A refrigeration compressor 5 is fixedly connected to the top of the tool magazine body 1. An air pump 6 is fixedly connected to the output end of the refrigeration compressor 5 through a pipe. A nozzle 7 is fixedly connected to the output end of the air pump 6 through a pipe. The output end of the nozzle 7 extends to the inner top of the tool magazine body 1. A vibration rod 8 is rotatably connected inside the tool magazine body 1. A drive assembly for driving the hexagonal base 2 to rotate is installed inside the tool magazine body 1. A fixing assembly for driving the arc-shaped clamping plate 4 to move along the length direction of the guide slide rod 3 is installed at the hexagonal ends of the hexagonal base 2. A vibration mechanism for driving the vibration rod 8 to drive the hexagonal base 2 to vibrate is installed inside the tool magazine body 1.

[0035] The drive assembly includes a drive worm 9 fixedly connected to one end of the hexagonal base 2, a drive worm wheel 10 rotatably connected to the inner top of the tool magazine body 1 and meshing with the drive worm 9, and a drive motor 11 fixedly connected to the inner top of the tool magazine body 1, with the output end of the drive motor 11 fixedly connected to the drive worm 9.

[0036] Furthermore, the fixing component includes a guide groove 12 opened at one end of the hexagonal base 2, a U-shaped slide rod 13 slidably connected inside the guide groove 12, a fixed electric push rod 14 fixedly connected to one end of the hexagonal base 2, the output end of the fixed electric push rod 14 fixedly connected to the U-shaped slide rod 13, a fixed inclined rod 15 adapted to the U-shaped slide rod 13 fixedly connected to one end of the arc-shaped clamp 4, and a return spring 16 fixedly connected to one end of the arc-shaped clamp 4, the return spring 16 being sleeved on one end of the guide slide rod 3;

[0037] Furthermore, one end of the U-shaped slide bar 13 is symmetrically rotatably connected to an abutting roller 24, which rolls and abuts against the fixed inclined bar 15;

[0038] Furthermore, a rubber gasket 25 is fixedly connected to the inner side of the arc-shaped clamp 4;

[0039] Furthermore, one end of the arc-shaped clamp 4 is symmetrically and fixedly connected with an arc-shaped extension edge 26.

[0040] In use, the drive motor 11 is first started to drive the drive worm gear 10 to mesh with the drive worm 9, and drive the hexagonal base 2 to rotate the arc-shaped clamping plate 4 at one corner to the tool magazine body 1 to receive the replacement tool. The CNC machine tool moves the tool between two adjacent arc-shaped clamping plates 4. The fixed electric push rod 14 is started to drive the U-shaped slide rod 13 to move towards the arc-shaped clamping plate 4 along the length of the guide slide 12. At the same time, the U-shaped slide rod 13 forms a sliding contact with the two fixed inclined rods 15, and pushes the two fixed inclined rods 15 to drive the two arc-shaped clamping plates 4 to move towards each other along the length of the guide slide rod 3. This causes the two arc-shaped clamping plates 4 to compress the return spring 16 along the length of the guide slide rod 3, resulting in a contraction deformation. The two arc-shaped clamping plates 4 drive the rubber pad 25 to form a flexible clamping and fixing with the tool. At the same time, the arc-shaped extension edge 26 is set to increase the clamping area between the arc-shaped clamping plate 4 and the tool, and improve the clamping stability of the arc-shaped clamping plate 4 for the tool.

[0041] Next, the drive motor 11 is started to drive the drive worm gear 10 to mesh with the drive worm 9, and the drive worm 9 drives the hexagonal base 2 to drive the arc-shaped clamping plate 4 holding the tool to rotate below the nozzle 7. At this time, by starting the air pump 6 and the refrigeration compressor 5, the air cooled by the refrigeration compressor 5 is blown by the air pump 6 and the nozzle 7 onto the surface of the tool held by the arc-shaped clamping plate 4, thereby forming heat exchange and cooling with the tool, and blowing away the debris adhering to the surface of the tool quickly. At the same time, the vibration mechanism is started to drive the hexagonal base 2 to drive the tool held by the arc-shaped clamping plate 4 to vibrate at high frequency, further improving the efficiency of debris separation from the tool. This facilitates the rapid cooling of the tool and debris removal, reduces the wear caused by long-term tool thermal deformation and friction between the tool and debris, and improves the precision of the tool.

[0042] Reference Figure 2 - Figure 4 The vibration mechanism includes a vibration rubber block 17 fixedly connected to the bottom of the tool magazine body 1. One end of the vibration rod 8 passes through the tool magazine body 1 and extends into the interior of the vibration rubber block 17. An eccentric block 18 is fixedly connected to one end of the vibration rod 8. A buffer rubber ring 19 is sleeved on the hinge end of the vibration rod 8 and the tool magazine body 1. The buffer rubber ring 19 is fixedly connected to the tool magazine body 1. A rotating assembly for driving the vibration rod 8 to rotate is installed inside the tool magazine body 1.

[0043] The rotating assembly includes a vibrating worm gear 20 rotatably connected to the bottom of the tool magazine body 1. A traction rubber ring 21 is fixedly connected inside the vibrating worm gear 20 and is fixedly connected to the vibrating rod 8. A vibrating worm 22 that meshes with the vibrating worm gear 20 is rotatably connected to the bottom of the tool magazine body 1. A vibrating motor 23 is fixedly connected to the bottom of the tool magazine body 1 and the output end of the vibrating motor 23 is fixedly connected to the vibrating worm 22.

[0044] In use, the vibration motor 23 drives the vibration worm 22 to mesh with the vibration worm wheel 20, causing the vibration worm wheel 20 to drive the traction rubber ring 21 to rotate. Simultaneously, the traction rubber ring 21 drives the vibration rod 8 to rotate, causing the vibration rod 8 to drive the eccentric block 18 to rotate eccentrically. This causes the eccentric block 18 to drive the vibration rod 8 to vibrate. At the same time, one end of the vibration rod 8 compresses the traction rubber ring 21, causing deformation, while the other end compresses the vibration rubber block 17, causing deformation. Utilizing the rebound characteristics of the vibration rubber block 17, the vibration rod 8 is pushed back to its original position. This causes the vibration rubber block 17 to drive the hexagonal base 2 to vibrate, which in turn causes the hexagonal base 2 to drive the arc-shaped clamping plate 4 and the cutting tool to vibrate. This vibration causes the debris adhering to the cutting tool surface to be quickly detached from the tool surface, effectively improving the efficiency of debris detachment and enhancing the practicality of the device.

[0045] The implementation principle of the automatic tool switching device for high-precision component processing in this embodiment is as follows: First, by activating the fixed electric push rod 14, the U-shaped slide rod 13 is driven to move towards the arc-shaped clamping plate 4 along the length direction of the guide slide groove 12. At the same time, the U-shaped slide rod 13 slides against the two fixed inclined rods 15, and pushes the two fixed inclined rods 15 to drive the two arc-shaped clamping plates 4 to move towards each other along the length direction of the guide slide rod 3. As a result, the two arc-shaped clamping plates 4 compress the return spring 16 along the length direction of the guide slide rod 3 to generate contraction deformation, and the two arc-shaped clamping plates 4 drive the rubber pad 25 to form a flexible clamping and fixing with the tool.

[0046] Then, the drive motor 11 is started to drive the drive worm gear 10 to mesh with the drive worm 9, and the drive worm 9 drives the hexagonal base 2 to drive the arc-shaped clamping plate 4 holding the tool to rotate to below the nozzle 7. At this time, by starting the air pump 6 and the refrigeration compressor 5, the air cooled by the refrigeration compressor 5 is blown by the air pump 6 and the nozzle 7 onto the surface of the tool held by the arc-shaped clamping plate 4, thereby forming heat exchange and cooling with the tool, and blowing away the debris adhering to the surface of the tool quickly.

[0047] Simultaneously, by starting the vibration motor 23, the vibration worm 22 is driven to mesh with the vibration worm wheel 20, causing the vibration worm wheel 20 to drive the traction rubber ring 21 to rotate. The traction rubber ring 21 drives the vibration rod 8 to rotate, causing the vibration rod 8 to drive the eccentric block 18 to rotate eccentrically. This causes the eccentric block 18 to drive the vibration rod 8 to vibrate. At the same time, one end of the vibration rod 8 squeezes the traction rubber ring 21 to deform, and the other end of the vibration rod 8 squeezes the vibration rubber block 17 to deform. Utilizing the rebound characteristics of the vibration rubber block 17, the vibration rod 8 is pushed to reset, causing the vibration rubber block 17 to drive the hexagonal base 2 to vibrate. This, in turn, causes the hexagonal base 2 to drive the arc-shaped clamping plate 4 and the cutting tool to vibrate, thereby causing the debris adhering to the surface of the cutting tool to be vibrated and quickly detach from the surface of the cutting tool.
