[0022] This utility model provides, for example Figures 1-4 The CNC chamfering machine robot shown includes a robot body 4 set above the operating table 1. An electric slide rail 2 is fixedly installed on the top of the operating table 1. An electric slide block 3 is fitted on the electric slide rail 2. The robot body 4 is installed on the electric slide block 3. The electric slide block 3 can move on the electric slide rail 2, thereby driving the robot body 4 to move and expand the coverage area.
[0023] The electric slide rail 2, electric slide block 3, and robotic arm body 4 are all connected to the factory's power supply.
[0024] The top of the operating table 1 is fixedly installed with a chamfering machine body 14 for chamfering. The chamfering machine body 14 includes a motor, grinding wheel and other structures. The chamfering machine body 14 cooperates with the robot body 4 to realize functions such as automatic chamfering. The cooperation between the two is carried out by the CNC layer (CNC system). The schemes for CNC and robot to realize handshake, call macro program, synchronize IO and other functions through EtherCAT / PROFINET have been disclosed in a large number of documents / standards, and will not be elaborated here.
[0025] Considering that most CNC chamfering machines in the present technology use general three-jaw manipulators, but for cylindrical workpieces, there are problems of unstable clamping and inaccurate positioning, which reduces processing efficiency, in order to ensure gripping stability, a gripper 5 is connected to the end of the manipulator body 4, and the gripper 5 is V-shaped.
[0026] To fix the cylindrical workpiece, through slots 6 are provided on both sides of the clamp 5. A slider 7 is slidably installed inside the through slot 6. Both the through slot 6 and the slider 7 are cross-shaped to ensure the stability of the slider 7 sliding inside the through slot 6. At the same time, a ball bearing structure is provided between the slider 7 and the inner wall of the through slot 6 to improve the smoothness of the slider 7 sliding inside the through slot 6 and reduce wear.
[0027] A pressure plate 9 is provided on the slider 7, and an electric push rod 10 is installed inside the through groove 6. The slider 7 is fixedly connected to the telescopic end of the electric push rod 10, and the slider 7 and the electric push rod 10 are distributed in a T-shape.
[0028] In actual use, refer to Figure 3 As shown, the telescopic end of the control electric push rod 10 extends, driving the slider 7 and pressure plate 9 to move downward. Then, the robot body 4 controls the gripper 5 to clamp onto the cylindrical workpiece from top to bottom. Then, the telescopic end of the control electric push rod 10 retracts, driving the slider 7 and pressure plate 9 to move upward and reset. The pressure plate 9 then squeezes the cylindrical workpiece from bottom to top. At this time, the gripper 5 and the two pressure plates 9 cooperate to fix the cylindrical workpiece, ensuring the chamfering effect.
[0029] Because the gripper 5 is V-shaped and the slider 7 can slide flexibly inside the sliding channel 8, it is suitable for fixing cylindrical workpieces with various outer diameters.
[0030] In addition, support seats are provided at both ends of the top of the operating table 1. The top of the support seats is an arc-shaped concave shape. The two ends of the workpiece are placed on the top of the two support seats respectively, so that the middle section of the workpiece is suspended in the air. During the gripping process, the pressure plate 9 and the like will not contact the top of the operating table 1, ensuring the gripping efficiency.
[0031] Furthermore, multiple support bases can be installed at both ends of the top of the operating table 1, which can accommodate a large number of workpieces at the same time, and can be adjusted according to the specific usage.
[0032] Considering that if the pressure plate 9 is directly fixed on the slider 7 and the distance between the two inclined walls of the gripper 5 is too long, it is easy for the workpiece to be unable to pass between the two ends of the pressure plates 9 when gripping large workpieces; while if the distance between the two inclined walls of the gripper 5 is too short, it is difficult for the pressure plate 9 to effectively contact and squeeze the workpiece. In order to improve the efficiency of the robot body 4, a sliding channel 8 is provided on the slider 7. The pressure plate 9 slides inside the sliding channel 8. A ball bearing or other structure is provided between the pressure plate 9 and the inner wall of the sliding channel 8 to improve the smoothness of the pressure plate 9 sliding inside the sliding channel 8 and reduce wear.
[0033] Guide plates 11 are fixedly connected to both outer walls of the grabber 5, as shown in the reference. Figure 3 As shown, the distance between the guide plate 11 and the outer wall of the grabber 5 gradually increases from top to bottom.
[0034] A guide groove 12 is provided on the side of the guide plate 11 near the grabber 5. A guide block 13 is slidably arranged inside the guide groove 12. The guide block 13 is fixedly connected to the corresponding pressure plate 9. Both the guide groove 12 and the guide block 13 are T-shaped to ensure the stability of the guide block 13 sliding inside the guide groove 12. At the same time, a ball bearing or other structure is provided between the guide block 13 and the inner wall of the guide groove 12 to improve the smoothness of the guide block 13 sliding inside the guide groove 12 and reduce wear.
[0035] Specifically, when the telescopic end of the control electric push rod 10 extends and drives the slider 7 and pressure plate 9 to move downward, the two pressure plates 9 will also move in opposite directions under the guidance of the guide plate 11, guide groove 12, etc. The distance between the two pressure plates 9 at the ends that are close to each other increases, which does not affect the workpiece entering the gripper 5.
[0036] When the extension end of the control electric push rod 10 is retracted, it drives the slider 7 and pressure plate 9 to move upward and reset. Under the guidance of the guide plate 11, guide groove 12, etc., the two pressure plates 9 will also move towards each other. The distance between the two pressure plates 9 and the end that is close to each other becomes smaller, ensuring that they can contact the workpiece that has entered the grabber 5, thereby squeezing and fixing it.
[0037] Furthermore, the ends of the two pressure plates 9 that are close to each other will not touch.
[0038] This utility model, through the setting of gripper 5, guide plate 11, guide groove 12 and other structures, is suitable for gripping and fixing various cylindrical workpieces with different outer diameters, ensuring the chamfering effect. At the same time, the sliding design of the pressure plate 9 does not affect the workpiece entering the gripper 5 and being squeezed efficiently, thus improving the efficiency of the CNC chamfering machine robot.
