Inside the channel is a placement platform. The unloading mechanism includes a mounting frame, a cylinder, a clamping plate, and a positioning rod. A positioning groove is provided on the upper surface of the placement platform. When it is necessary to unload the workpiece... When unloading the workpiece from the table, simply use cylinder two to move the table upwards so that the positioning groove on the table surface and the positioning rod are on the same horizontal line. Then, use cylinder one to control the positioning rod so that the positioning rod is inserted into the positioning groove, thus lifting the workpiece on the table. Then, use cylinder two to move the table downwards, and use the sliding mechanism to move the unloading mechanism to complete the unloading. In terms of overall operation, this unloading device for automated CNC machine tools improves the convenience of operation and the stability of unloading the workpiece, prevents the workpiece from being bumped, and improves product quality.

[0003] According to its publicly available technical solutions, in the existing technology, after the workpiece is processed, the mechanical claw is used to clamp the workpiece. In this process, the mechanical claw actively clamps the workpiece, which can easily cause slight deformation of the workpiece. In addition, the workpiece may fall off during the mechanical claw's gripping and transfer process, which can lead to damage to the workpiece. Utility Model Content

[0004] To address the shortcomings of existing technologies, the purpose of this invention is to provide a CNC machine tool unloading device to solve the problems mentioned in the background. This invention utilizes the workpiece's own weight to slide and discharge the workpiece through an installed tilting component, simplifying the device structure and reducing manufacturing costs. Unloading can be completed without the need for an additional robotic arm, avoiding workpiece deformation caused by active clamping or pushing.

[0005] To achieve the above objectives, this utility model is implemented through the following technical solution: a CNC machine tool unloading device, including an unloading device body, the unloading device body including a cabinet, an inclined component and a cleaning mechanism, the side of the cabinet is provided with an outlet, the interior of the cabinet is hollow, a support platform is welded to the other side of the cabinet, the inclined component is disposed on the top surface of the cabinet, and the side of the inclined plate is welded to the inner wall of the cabinet.

Both ends of the rotating shaft are inserted into the inner wall of the cabinet through bearings. A torsion spring is fitted onto the surface of the rotating shaft. One end of the torsion spring is welded to the surface of the rotating shaft, and the other end of the torsion spring is welded to the bottom surface of the flap.

[0007] Furthermore, both the first push plate and the second push plate are located on the top surface of the flip plate, and a traction rope is connected to the bottom surface of the first protrusion.

[0008] Furthermore, the other end of the traction rope is connected to the bottom surface of the second protrusion, and both the first and second protrusions are inserted into the surface of the flap.

This prevents debris from scratching the workpiece surface during the sliding discharge process, eliminating the need for manual cleaning of the flip plate surface later. In addition, the water flow covering the flip plate surface reduces the friction during the workpiece sliding process, thereby reducing wear on the workpiece. Attached Figure Description

[0016] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0017] Please see Figures 1 to 4 This utility model provides the following technical solution: a CNC machine tool unloading device, including an unloading device body, the unloading device body including a cabinet 1, an inclined component 2 and a cleaning mechanism 3, the side of the cabinet 1 is provided with an outlet 13, the interior of the cabinet 1 is hollow, the other side of the cabinet 1 is welded with a support platform 7, the inclined component 2 is set on the top surface of the cabinet 1, the side of the inclined plate 14 is welded to the inner wall of the cabinet 1, the electric push rod 8 pushes the first push plate 5 and the second push plate 6 to move, thereby linking the flip plate 20 to flip, the flip plate 20 flipping and linking the cleaning mechanism 3 to clean the debris on the surface of the flip plate 20, the flip plate 20 flipping at the same time causing the workpiece to slide out, the unloading device is embedded in the surface of the CNC machine tool to support the workpiece.

[0018] In this embodiment, the tilting assembly 2 includes a rotating shaft 11, a first push plate 5, a second push plate 6, and a first protrusion 9. A flap 20 is welded to the top surface of the rotating shaft 11. Both ends of the rotating shaft 11 are inserted into the inner wall of the cabinet 1 via bearings. A torsion spring is fitted onto the surface of the rotating shaft 11, with one end welded to the surface of the rotating shaft 11 and the other end welded to the bottom surface of the flap 20. The first push plate 5 and the second push plate 6 are both located on the top surface of the flap 20. The bottom surface of the first protrusion 9 is connected to... A traction rope 10 is attached, with the other end of the traction rope 10 connected to the bottom surface of the second protrusion 12. Both the first protrusion 9 and the second protrusion 12 are inserted into the surface of the flip plate 20. A spring rod is inserted inside both the first protrusion 9 and the second protrusion 12. The other end of the spring rod is welded to the inner wall of the flip plate 20. During the process of the electric push rod 8 pushing the first push plate 5 completely away from the surface of the flip plate 20, the restriction on the workpiece is released. The workpiece slides down to the surface of the inclined plate 14 under the action of gravity and is discharged through the surface of the inclined plate 14.

[0019] In this embodiment, the cleaning mechanism 3 includes a water tank 4, a slider 16, and a waste box 15. The water tank 4 is installed on the top surface of the flip plate 20. An electric push rod 8 is welded to the side of the water tank 4. A special-shaped water pipe 19 is inserted inside the water tank 4. An interlayer 18 is provided inside the special-shaped water pipe 19. A water inlet is opened on the top surface of the special-shaped water pipe 19, and a water outlet is opened at the end of the special-shaped water pipe 19. The slider 16 is inserted inside the interlayer 18. A spring 17 is welded to the end of the slider 16. The other end of the spring 17 is welded to the inner wall of the special-shaped water pipe 19. The top surface of the waste box 15 is welded to the bottom surface of the flip plate 20. A filter screen is installed inside the waste box 15. When the flip plate 20 flips, it drives the water tank 4 to rotate. During the tilting process of the water tank 4, the slider 16 slides inside the interlayer 18, releasing the blockage of the water inlet, thereby allowing the water outlet to drain water outward. The water flow washes away the debris on the surface of the flip plate 20.

[0020] Working principle: In the initial state, both the first push plate 5 and the second push plate 6 are placed on the top surface of the flip plate 20. At this time, due to the gravity of the first push plate 5 and the second push plate 6, the flip plate 20 cannot be flipped. The workpiece is placed on the top surface of the flip plate 20. After the workpiece is processed, the electric push rod 8 is activated. The electric push rod 8 pushes the first push plate 5 to move, and the movement of the first push plate 5 drives the second push plate 6 to move. When the second push plate 6 is completely moved to the top surface of the support platform 7, the electric push rod 8 stops working. At this time, the weight on one side of the flip plate 20 decreases, and the flip plate 20 slowly rotates around the rotating shaft 11. The workpiece on the flip plate 20 is blocked by the second protrusion 12 and cannot move. The flip plate 20 flips, driving the water tank 4 to rotate. The flip plate 20 rotates synchronously with the waste box 15. When the flip plate 20 rotates to the point where the waste box 15 contacts the inner wall of the cabinet 1, it stops rotating. During the flipping process of the water tank 4, the slider 16 inside the water tank 4 slides in the interlayer 18 of the irregular water pipe 19 under the action of gravity. The spring 17 enters the compressed state. During the sliding process, the slider 16 releases the blockage of the water inlet hole on the top surface of the irregular water pipe 19. The water inside the water tank 4 enters the interior of the irregular water pipe 19 through the water inlet hole. The water inside the irregular water pipe 19 flows to the surface of the flip plate 20 through the water outlet hole at the end of the irregular water pipe 19. The water flow washes away the debris generated during the processing of the flip plate 20 surface and finally flows into the waste box 15. At this time, the electric push rod 8 continues to push the first push plate. 5. When the first push plate 5 is completely detached from the surface of the flip plate 20, the electric push rod 8 is turned off. During the process of the first push plate 5 detaching from the flip plate 20, the first protrusion 9 is displaced upward by the spring force of the spring rod. The spring force of the first protrusion is greater than that of the spring rod of the second protrusion. During the displacement of the first protrusion 9, the traction rope 10 is pulled to move. At this time, the second protrusion 12 is displaced downward by the pulling force of the traction rope 10. When the second protrusion 12 is completely inside the flip plate 20, the workpiece is released from the restriction and slides downward. The workpiece slides along the flip plate 20 to the surface of the inclined plate 14. The surface of the inclined plate 14 is embedded with ball bearings. The workpiece slides along the inclined plate 14 to the discharge port 13 and is discharged. During the process of the workpiece detaching from the flip plate 20... The flip plate 20 is flipped in the opposite direction by the force of the torsion spring. The flip plate 20 flips and drives the water tank 4 and the waste box 15 to move synchronously. When the flip plate 20 rotates to the point that the bottom surface of the flip plate 20 contacts the top surface of the cabinet 1, it stops rotating. At this time, the slider 16 inside the water tank 4 is moved to the initial position by the elastic force of the spring 17, and the water inlet of the irregular water pipe 19 is blocked. The electric push rod 8 is retracted to the initial state and the first push plate 5 and the second push plate 6 are placed back on the surface of the flip plate 20. During the process of placing the second push plate 6 on the surface of the flip plate 20, the first protrusion 9 is pressed into the surface of the flip plate 20. The second protrusion 12 is moved upward to the initial position by the elastic force of the spring rod. The next workpiece is placed on the surface of the flip plate 20, and the above process is repeated.

It is obvious to those skilled in the art that this utility model is not limited to the details of the above exemplary embodiments, and that it can be implemented in other specific forms without departing from the spirit or basic characteristics of this utility model.

Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
