Description
Technical Field
[0001] This utility model relates to the field of impeller processing technology, and in particular to a feeding mechanism based on an impeller dynamic balancing and de-weighing machine. Background Technology
[0002] Impeller dynamic balancing and weight removal machines are automated equipment specifically designed for dynamic balancing correction of impeller products. Their core working logic is to receive the magnitude and phase position parameters of the impeller imbalance, and then automatically remove the corresponding mass of material at a specific position on the product to make the impeller meet the specified dynamic balancing accuracy requirements. They are widely used in impeller processing production lines in aerospace, automobile manufacturing, general machinery and other fields.
[0003] However, existing dynamic balancing and weight-removing machines have significant shortcomings in practical use.
[0004] Firstly, the equipment adopts a structural design oriented towards manual operation, with a compact and relatively enclosed internal space layout. This makes it difficult for the six-axis industrial robot and its end effector to effectively extend into the working area inside the equipment, thus hindering the smooth completion of automated workpiece loading and unloading operations. This restricts the integration and realization of automated loading and unloading functions and affects the improvement of the automation level of the production line.
[0005] Secondly, the existing equipment lacks an efficient buffering and changeover mechanism. When NG materials accumulate, it can easily lead to a decrease in production line cycle time. Furthermore, the fixture changeover operation for impellers of different specifications is complex and time-consuming. At the same time, the workpiece transfer and positioning accuracy is insufficient, making it difficult to meet the needs of high-precision production. Utility Model Content

[0025] Working principle: The operation process mainly includes six stages: material feeding and positioning, contour gripping, precise transfer, impeller de-weighting, process connection and quick changeover. The core electrical control adopts Siemens S7-1200 series PLC controller, the servo motor is Panasonic MSMF042L1U2M model, the sensor is Omron E3Z-D61 model, and the cylinder is SMC series product. All electronic and electrical equipment are coordinated and controlled by the PLC controller.
[0026] Material loading and positioning stage: The PLC controller issues a command, the secondary telescopic platform retracts to the origin, the three-axis cylinder 13 drives the buffer placement block 11 of the lifting buffer platform to rise, the six-axis robot receives the signal and places the impeller workpiece on the empty buffer placement block 11, and the sensor 15 detects that the workpiece is in place and sends a feedback signal to the PLC.
[0027] In the contour gripping stage: the PLC controller controls the servo motor 25 to start, driving the ball screw 23 to rotate. Through the transmission action of the nut connecting block 21, the moving base plate is pushed along the first linear guide rail 17 to the buffer station. After receiving the signal, the thin pneumatic gripper 29 closes and synchronously clamps the upper and lower ends of the impeller through the contour clamp 26 to ensure the vertical posture of the impeller's inner hole. After clamping in place, the three-axis cylinder 13 drives the lifting buffer platform to descend and reset.
[0028] Precision transfer stage: The rodless cylinder 14 is activated, which drives the contour gripper to extend along the second linear guide rail 18 with the moving plate 16, completing the second-level telescopic action. Then, the servo motor 25 drives the ball screw 23 again, so that the moving base plate is precisely pushed to the de-weighting station. After receiving the command, the slide cylinder 31 descends, the thin gripper 29 opens, and the impeller is placed smoothly in the de-weighting station to complete the de-weighting and loading. The positional accuracy of all actions is achieved through the closed-loop control of the sensor 15 and the PLC controller.
[0029] Impeller de-weighting stage: The slide cylinder 31 rises and resets, and the secondary telescopic platform retracts to the origin under the coordinated action of the servo motor 25 and the rodless cylinder 14. After receiving the PLC signal, the de-weighting machine closes the door and performs cutting de-weighting operation.
[0030] Process connection stage: If the de-dust removal machine has not yet completed the processing of the previous workpiece when the robot loads the material, the PLC controller detects the de-dust removal station occupancy signal and controls another lifting buffer platform to rise. The new workpiece is temporarily stored in the buffer platform to avoid the robot. After the de-dust removal is completed, the workpiece is transferred to the buffer placement block 11 to be picked up by the robot, ensuring the continuous operation of the production line.
[0031] Rapid changeover phase: When it is necessary to change the impeller specification, the relevant actions can be paused through the PLC controller, and the copying fixture 26 can be disassembled and installed separately or the copying jaws can be replaced as a whole. After the changeover is completed, the parameters can be reset through the PLC controller to adapt to the processing requirements of the new impeller specification.
[0032] Throughout the entire operation process, the PLC controller receives position signals from each sensor 15 and precisely controls the timing of the actions of the servo motors and cylinders to achieve automated and high-precision feeding operations, meeting the needs of continuous production. Example 2:
[0033] A feeding mechanism based on an impeller dynamic balancing de-weighing machine, such as Figure 1-8As shown, this embodiment makes the following additions based on embodiment 1: The ground rail base adopts a double-layer structure consisting of an upper horizontal adjustment plate 5 and a lower base plate 6. First, the lower base plate 6 is fixed to the ground with chemical bolts 7 to ensure the overall installation stability. Then, the horizontal adjustment bolts 4 on the upper horizontal adjustment plate 5 are used for horizontal calibration. Through the cooperation of the fine-tuning fixing block 3 and the positioning block 2, the installation accuracy of the ground rail base meets the equipment operation requirements, providing a flat and stable foundation for the subsequent installation of components.
[0034] Welded frame assembly: The welded frame 9 is a cubic skeleton welded from square steel tubes. The top and bottom surfaces are welded with mounting surfaces to ensure the flatness of the connection. The bottom surface of the welded frame 9 is placed on the linear guide rail 1 of the ground rail base, so that the indexing pin 10 set on the bottom surface is precisely matched with the positioning structure on the upper horizontal adjustment plate 5 of the ground rail base. The indexing pin 10 realizes the rapid positioning and fixing of the welded frame 9. At the same time, the linear guide rail 1 can realize the manual clearance of the welded frame 9, with a maximum clearance distance of 700mm and a reset accuracy of ≤±0.05mm.
[0035] Assembly of the secondary telescopic platform: The bottom surface of the fixed base plate 8 of the secondary telescopic platform is fixedly connected to the top surface of the welded frame 9. The shims 19 are evenly distributed and fixed along the top surface of the fixed base plate 8. The first linear guide rail 17 and the second linear guide rail 18 are respectively installed on both sides of the movable base plate. The bottom slider is fixed to the shims 19, and the top slider is fixed to the movable plate 16 to ensure the smooth sliding of the movable plate 16.

The servo motor 25 is fixed to the motor base 24 and connected to the ball screw 23 through a coupling. The screw nut connecting block 2...

The other end of the connecting plate 34 is fixed with a drag chain 35 and connected to the fixed base plate 8, forming a secondary telescopic structure. A cylinder mounting plate 32 is vertically fixed to the top of the movable plate 16. A reinforcing rib 33 connects the two to improve the structural strength. A slide cylinder 31 is fixed to one side of the cylinder mounting plate 32 with bolts. A transition plate 30 is vertically fixed to the cylinder mounting plate 32 and a thin gripper 29 is installed, completing the overall assembly of the secondary telescopic platform.
[0036] Installation of the contour gripper: The finger connecting block 28 is fixedly connected to the thin pneumatic gripper 29. The bottom side of the gripper 27 is fastened to the finger connecting block 28 with screws. The other end of the gripper 27 is fixed with the contour clamp 26 to ensure that the contour clamp 26 fits precisely with the shape of the impeller, ensuring gripping stability and correct posture. After installation, the opening and closing flexibility of the gripper 27 and the coaxiality of the contour clamp 26 need to be tested.
[0037] Lifting buffer table assembly: Cylinder mounting block 12 is fixedly connected to fixed base plate 8. Three-axis cylinder 13 is fixed to one side of cylinder mounting block 12 with screws. Buffer placement block 11 is fixed to the top of piston rod of three-axis cylinder 13 to ensure that buffer placement block 11 rises and falls smoothly when three-axis cylinder 13 extends and retracts. After installation, the lifting accuracy and load-bearing capacity of buffer placement block 11 need to be adjusted to ensure that the workpiece is placed stably.
[0038] Electrical system connection: The electrical components such as servo motor 25, rodless cylinder 14, slide cylinder 31, thin gripper 29, three-axis cylinder 13, and sensor 15 are connected to the PLC controller. The sensor 15 and the sensing plate 22 work together to realize position detection. All pneumatic components are connected to the air source through air pipes.
