Description

Technical Field

[0001] The present invention relates to the technical field of testing equipment, in particular to a handling manipulator testing platform. Background Art

[0002] A handling robot is an automated device that mimics certain movements of the human hand and arm, used to grasp, move objects, or operate tools according to a fixed program. The robot's structural components typically undergo a series of tests to ensure their performance and reliability. The motor rotor in the robot requires dynamic balancing testing, as imbalanced rotors can generate vibrations during operation, accelerating wear of components like bearings and reducing the robot's service life.

[0003] The motor rotor structural components of the handling robot are often subjected to dynamic balancing tests using a dynamic balancing tester. The existing dynamic balancing test mainly consists of a machine, two support fixtures that can be adjusted and mounted on the machine, and a pulley frame that is rotatably mounted on the machine. During the test, the left and right shafts of the rotor are respectively placed on the rollers of the two support fixtures, and then the pulley frame is rotated so that the belt on it presses the rotor from top to bottom appropriately. Then the pulley frame can drive the belt to rotate, and the rotor will rotate under the action of friction. The display screen on the dynamic balancing tester will display the vibration of the rotor and the imbalance data obtained by analysis in real time, and the counterweight method will be used to counterweight the left and right parts of the rotor until the imbalance of the rotor meets the standard.

[0004] The counterweight method involves placing a corresponding number of counterweight washers on the cylindrical protrusions on the left and right sides of the rotor. The rotor is then driven to rotate and the data is observed. This process is repeated until the number of washers added meets the required rotor imbalance. Finally, the washers are riveted to the cylindrical protrusions using a riveting gun. However, not only do the washers require manual handling and installation, which is inconvenient, but they also sit loosely on the cylindrical protrusions and can easily fall off due to vibration or shaking during rotor rotation, affecting the dynamic balance test of the motor rotor structural components of the handling robot.

[0039] Working principle: First, place the two extended shafts of the rotor 4 on the rollers of the two supporting fixtures 5, and center the rotor 4 on the two supporting fixtures 5. Then rotate the rack connected to the outside of the belt 2 so that the belt 2 can properly press the rotor 4 from top to bottom. Figure 1 and Figure 2As shown, this is a well-known prior art and will not be described in detail. When placing the rotor 4, make sure that the center of one of the cylindrical protrusions on the left and right sides of the rotor 4 corresponds to the center of the two hollow rods 7 (this can be achieved with the help of a centering tool or clamp, this is a well-known prior art and will not be described in detail). Then, start the table 3 to drive the belt 2 to rotate, and the belt 2 can drive the rotor 4 to rotate. The display screen 1 will display the vibration of the rotor 4 and the analyzed imbalance data in real time. Then, based on the data analysis, close the table 3 to stop the rotation of the rotor 4, and make sure that the center of one of the cylindrical protrusions on the left and right sides of the rotor 4 still corresponds to the center of the two hollow rods 7. According to the imbalance of the left and right sides of the rotor 4, the cylindrical protrusions on the left and right sides of the rotor 4 are counterweighted.

[0040] When the cylindrical protrusion on one side that needs to be counterweighted is being counterweighted, first start an electric push rod 28, which can drive the disc 9 to move in the direction of the rotor 4. The disc 9 can drive multiple fixed blocks 13, multiple guide columns 14, multiple support rods 23 and multiple trapezoidal blocks 28 to move together. During the process, the connecting block 22 outside each support rod 23 will squeeze the corresponding inclined block 21. Under the action of the squeezing force, each support rod 23 will synchronously approach the hollow in the corresponding chute 11. The rod 7 slides, and each support rod 23 drives the guide column 14 connected to it to slide in the corresponding fixed block 13, and each support rod 23 pulls the spring 12 connected to the corresponding fixed block 13, and each support rod 23 also drives the trapezoidal block 28 connected to it to move closer to the hollow rod 7. When the connecting block 22 outside each support rod 23 slides away from the corresponding inclined block 21, each connecting block 22 slides on the corresponding flat plate 20, and at this time each connecting block Each ladder block 35 will drive the pillar 38 connected to it to slide inward in the corresponding columnar shell 36 and squeeze the corresponding spring four 37 until the multiple ladder blocks 35 slide out of the hollow rod 7 with the first washer 19.

[0041] It should be noted that the outer surface of the hollow rod 7 is made of rubber, and there is a certain friction between it and the inner ring surface of the washer 19. At this time, since the spring 2 17 is originally in an extruded state and the elastic force of the spring 2 17 is relatively small, the remaining washer 19 will be pushed through the slip ring 18 under the action of the spring 2 17. The inner ring surface of the remaining washer 19 will slowly slide in the direction of the outer rotor 4 of the hollow rod 7 under the action of the friction between it and the outer surface of the hollow rod 7. At this time, the first washer 19 It has already detached from the hollow rod 7 and is firmly held by the three trapezoidal blocks 28. Simultaneously, under the force of spring 4 37, the two ladder blocks 35 move away from each other to reset. The inner edge of the remaining washer 19 closest to the rotor 4 then contacts the inclined surfaces of the two ladder blocks 35. This prevents the ladder blocks 35 from sliding inward within the inner wall of the hollow rod 7 because the elastic force of spring 2 17 is relatively small, while the elastic force of spring 4 37 is greater than that of spring 2 17. As the electric push rod 2 8 continues to operate, the multiple ladder blocks 35 continue to move toward the rotor 4, holding the first washer 19. The first washer 19 is then positioned outside one of the cylindrical protrusions on one side of the rotor 4. It should also be noted that a rubber pad is connected to the end of the multiple ladder blocks 35 corresponding to the washer 19 to increase friction with the washer 19, allowing the multiple ladder blocks 35 to stably hold the first washer 19. It should also be noted that the motor 29, the concave block 26, the turntable 40, the connecting rod 30, the slide bar 27, the fixed plate 31, the arc block 32, the arc plate 25, and the press-type glue barrel 24 all move together with the support rod 23 at the top, and the nozzle of the press-type glue barrel 24 is combined with the Figure 6 It is seen in front of the trapezoidal block 28.

[0042] When the first washer 19 moves to the side wall close to the rotor 4, the motor 29 is started at this time, and the motor 29 drives the turntable 40 to rotate one circle. The turntable 40 drives the connecting rod 30 to swing back and forth once, and the connecting rod 30 drives the sliding rod 27 to slide close to and away from the pressing glue cylinder 24 in the inner wall of the fixed plate 31. The sliding rod 27 slides back and forth once, and then drives the arc block 32 to lightly squeeze and release the pressing glue cylinder 24 once (the pressing glue cylinder 24 is a method of relying on external squeezing to make the glue cylinder 24 The glue inside the press-type glue barrel 24 will drip along the nozzle onto the corresponding cylindrical protrusion. Then, as the electric push rod 28 continues to operate, the multiple ladder-shaped blocks 35 will fit the first clamped washer 19 against the side wall of the rotor 4. During this process, the washer 19 will push the glue against the side wall of the rotor 4. Under the action of the glue, the washer 19 can be fixed, and the weight of the added glue is small, which will not affect the counterweight. Similarly, in the same way, a washer 19 can be added to the cylindrical protrusion on the other side of the rotor 4 for counterweight, or a washer 19 can be added to the cylindrical protrusions at other positions on both sides of the rotor 4 for counterweight.

[0043] It should be noted that starting the electric push rod 1 6 can drive the hollow rod 7 and other components connected to the hollow rod 7 to move upward together, so that the rotor 4 can be placed on the two supporting fixtures 5 without hindrance. It should also be noted that when the electric push rod 2 8 retracts, it will drive the disc 9 to move away from the rotor 4, that is, the disc 9 will move back, and the disc 9 will drive the multiple support rods 23 and the multiple trapezoidal blocks 28 to move back. At this time, because the first washer 19 has been firmly connected to the wall of the rotor 4 by glue, the backward movement of the multiple trapezoidal blocks 28 will not drive the first washer 19 to move together. The first washer 19 will remain fixed on the cylindrical protrusion. When the multiple trapezoidal blocks 28 leave the surface of the first washer 19, under the action of the spring 3 33, the multiple trapezoidal blocks 28 will reset. At this time, as the electric push rod 2 8 continues to operate, the connecting blocks 22 on the multiple support rods 23 will fit on their corresponding flat plates 20 When the disc 9 is moved back, the multiple trapezoidal blocks 28 will also move back, and the inclined surfaces of the multiple trapezoidal blocks 28 will squeeze the outer ring edge of the washer 19 closest to the rotor 4 in the remaining washers 19. Then, under the action of the extrusion force, the multiple trapezoidal blocks 28 will eventually move back while moving away from the hollow rod 7. Finally, the connecting blocks 22 on the multiple support rods 23 will leave their corresponding flat plates 20 and under the action of the spring 12, the multiple connecting blocks 22 will move along the inclined surfaces of the corresponding inclined blocks 21, that is, the multiple connecting blocks 22 will move away from the hollow rod 7 synchronously, then the multiple support rods 23 and the multiple trapezoidal blocks 28 will also move away from the hollow rod 7 synchronously, until the disc 9, the multiple connecting blocks 22 and the multiple support rods 23 return to the state as shown in the figure. Figure 3 Status shown.

[0044] It should also be noted that when the motor rotor 4 structural components of the handling robot are subjected to a dynamic balancing test through a dynamic balancing tester, the counterweight washers 19 can be automatically added to the cylindrical protrusions on the left and right sides of the rotor 4, and the washers 19 can be fixed on the cylindrical protrusions with a small amount of glue. This is not only convenient to operate, but also the washers 19 will not fall off on the cylindrical protrusions due to vibration or shaking during the rotation of the rotor 4, thereby avoiding affecting the dynamic balancing test of the motor rotor 4 structural components of the handling robot.
