[0003] Existing cutting tools typically use a fixed nozzle to continuously blow air onto the outside of the tool to clean debris from its surface. However, this fixed nozzle sprays air in a linear, one-way direction, which can easily create blind spots at the corners of the tool's side, resulting in incomplete cleaning. In addition, the tool shank usually has slots, and a nozzle on only one side of the tool cannot effectively clean these slots on the outside of the shank.

[0004] Therefore, a dual-station tool changer for machining centers with integrated tool cleaning function is proposed to solve the problems mentioned above. Utility Model Content

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model. Example:

[0019] Please see Figure 1 - Figure 4 This embodiment of a machining center dual-station tool changer with integrated tool cleaning function includes a dual-station tool changer 1. The dual-station tool changer 1 includes a tool disc 2, a tool disc hydraulic drive 3, a hydraulic motor 4, and an air supply 5. The tool disc hydraulic drive 3 is located on one side of the tool disc 2. The upper end of the dual-station tool changer 1 is provided with a swing mechanism. The swing mechanism includes a motor 8 for driving, a cam 7 for pushing, and a swing plate 6 for swinging. A synchronous wheel 12 is fixedly connected to the outer side of the output end of the motor 8. A synchronous wheel 13 is provided on one side of the synchronous wheel 12. A conveyor belt 14 is provided between the synchronous wheel 12 and the synchronous wheel 13. A fixed rod 15 is fixedly connected to the upper end of the synchronous wheel 13. A gear 16 is fixedly connected to the upper end of the fixed rod 15. A sleeve 17 is provided on one side of the gear 16. Several brushes 19 are fixedly connected to the inner side of the sleeve 17. The cross-sectional shape of the brushes 19 is triangular. Several racks 18 are fixedly connected to the outer side of the sleeve 17. The gear 16 meshes with the rack 18. Cam 7 is fixedly connected to the output end of motor 8, and cam 7 is slidably connected to the inner side of swing plate 6. One end of swing plate 6 is rotatably connected to rotating rod 9, and the lower end of rotating rod 9 is rotatably connected to dual-station tool changing device 1. The upper end of the swing plate 6 is fixedly connected to an air storage tank 22. The upper end of the air storage tank 22 is connected to a nozzle 21, and one side of the upper end of the air storage tank 22 is connected to an air supply pipe 20. One end of the air supply pipe 20 is connected to the inside of the air supply machine 5. The rotation of the cutter head 2 by the cutter head hydraulic drive 3, the movement of the gripper by the hydraulic motor 4, the supply of air to the air pipe 20 by the air supply machine 5, and the rotation of the cam 7 by the motor 8 are all existing technologies and therefore are not described in detail in this embodiment. At this time, the cutter head 2 is rotated by the hydraulic drive motor 3. When the required tool rotates to the position facing the gripper, the hydraulic motor 4 drives the gripper to move, achieving the effect of clamping the tool set on one side of the cutter head 2. At this time, the air supply motor 5 is started, and the air supply motor 5 supplies air to the air storage tank 22 through the air supply pipe 20. The air storage tank 22 is connected to the nozzle 21, and the nozzle 21 blows air onto the tool inside the gripper. At the same time as the air supply motor 5 is started, the motor 8 is started. When the motor 8 rotates, it drives the cam 7 at the output end to rotate synchronously. When the cam 7 rotates, it pushes the swing plate 6 and moves one end of the swing plate 6 through the rotating rod 9. Rotary connection to the upper end of the dual-station tool changer 1. When the cam 7 pushes the swing plate 6, the swing plate 6 will swing at a certain angle around the rotating rod 9. By fixing the air storage tank 22 to the swing plate 6, the air storage tank 22 will drive the nozzle 21 to swing with the swing plate 6. Different sizes of tools will be used in the processing. The swing nozzle 21 can flexibly adapt to tools of different diameters and lengths by adjusting the swing angle and range. When the swing nozzle 21 swings, it can impact the contaminants on the tool surface from multiple angles. Compared with the cleaning of the fixed nozzle 21 in one direction, it can more effectively remove various contaminants on the tool surface and improve the cleaning efficiency. While the motor 8 rotates, the synchronous pulley 12 on the outer side of the output shaft of the motor 8 rotates along with the motor 8. Both synchronous pulley 12 and synchronous pulley 13 are engaged with the conveyor belt 14, which drives synchronous pulley 13 to rotate synchronously. When synchronous pulley 13 rotates, it drives gear 16 to rotate via the fixed rod 15 at its upper end. Gear 16 is engaged with sleeve 17, causing sleeve 17 to rotate synchronously. As sleeve 17 rotates, the brush 19 on the inner side of sleeve 17 rotates along with it. The hydraulic motor 4 drives the gripper to move, and the knife held inside the gripper... The upper end of the tool holder moves to the inside of the sleeve 17 along with the gripper. The brush 19 rotating inside the sleeve 17 can clean the debris on the outside of the tool holder, preventing damage to the spindle connection due to incomplete cleaning of the debris on the outside of the tool holder. A connecting rod is rotatably connected to the upper end of the sleeve 17, and the other end of the connecting rod is rotatably connected to the upper end of the gear 16. The connecting rod can provide rotational support for the rotation of the sleeve 17, improving the stability of the structure. The air supply pipe 20 will reciprocate at a certain angle with the swing plate 6, rather than rotating the air supply pipe 20. Therefore, the air supply pipe 20 will not get tangled when it reciprocates.

[0020] A protective box 23 is fitted on the outside of the motor 8. The motor 8 is fixedly connected to the inside of the protective box 23. The lower end of the protective box 23 is fixedly connected to the dual-station tool changer 1, and the output end of the motor 8 is connected to the protective box 23 through it. Synchronous pulley 12 and synchronous pulley 13 are both meshed with conveyor belt 14. The lower end of synchronous pulley 13 is rotatably connected to a rotating shaft, and the lower end of the rotating shaft is rotatably connected to the dual-station tool changer 1. A sliding rod 10 is fixedly connected to the lower end of the swing plate 6, and an arc-shaped sliding groove 11 is provided on the outer side of the sliding rod 10; At least two support rods are fixedly connected to the lower end of the arc-shaped chute 11, and the lower ends of the two support rods are fixedly connected to the dual-station tool changer 1. Specifically, by installing a protective box 23 on the outside of the motor 8, and a sealing ring at the connection between the output end of the motor 8 and the protective box 23, external moisture or other impurities can be prevented from entering the motor 8 during operation, thus preventing damage to the motor 8. By meshing and connecting both synchronous pulley 12 and synchronous pulley 13 with the conveyor belt 14, slippage of the conveyor belt 14 when it drives synchronous pulley 13 to rotate is prevented. A rotating shaft is rotatably connected to the lower end of synchronous pulley 13, which provides rotational support for the rotation of synchronous pulley 13. By sliding the sliding rod 10 to the inner side of the arc-shaped groove 11 and fixing the sliding rod 10 to the swing plate 6, the arc-shaped groove 11 provides rotational support for the synchronous pulley 13. The groove 11 provides sliding support for the sliding rod 10, and in turn, supports the swing of the swing plate 6, preventing the swing plate 6 from shaking during swing and causing the nozzle 21 to swing at an inaccurate angle. The brushes 19 have triangular cross-sections. The outer side of the handle is not a completely smooth plane, and usually has a relief groove, keyway, and engraving groove. Traditional brushes 19 are basically straight strips and cannot reach deep into the grooves to clean debris. However, each corner of the triangular cross-section brush 19 can be directly embedded into these narrow gaps. With the elastic deformation of the bristles, it can thoroughly sweep out chips, oil, and dust from the gaps, avoiding the accumulation of residual stains that affect the subsequent clamping accuracy of the handle and improving the clamping accuracy.

[0021] The working principle of the above embodiments is as follows: In use, the cutter head 2 is rotated by the hydraulic drive motor 3. When the required cutter rotates to the position facing the gripper, the hydraulic motor 4 drives the gripper to move, achieving the effect of clamping the cutter set on one side of the cutter head 2. At this time, the air supply motor 5 is started, and the air supply motor 5 supplies air to the air storage tank 22 through the air supply pipe 20. The air storage tank 22 is connected to the nozzle 21, and the nozzle 21 blows air onto the cutter inside the gripper. At the same time as the air supply motor 5 is started, the motor 8 is started. When the motor 8 rotates, it will... The cam 7 pushes the swing plate 6 back and forth, which in turn drives the nozzle 21 to swing back and forth at a certain angle, thus cleaning the debris on the outside of the tool. The synchronous wheel 13 drives the sleeve 17 to rotate, which in turn drives the inner brush 19 to rotate. The hydraulic motor 4 drives the gripper to move, and the tool handle at the top of the tool held by the gripper moves to the inside of the sleeve 17. The brush 19 rotating inside the sleeve 17 can clean the debris on the outside of the tool handle.

[0022] The installation, connection, or setting methods disclosed in this embodiment are all common mechanical connection methods. As long as they can achieve their beneficial effects, they can be implemented. Therefore, this embodiment will not elaborate on their specific structural composition and working principle.

[0023] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
