Description

Technical Field

[0001] The present invention relates to the technical field of dynamic balancing of rotating equipment, in particular to a dynamic balancing adjustment device for rotating equipment. Background Art

[0002] Rotating equipment is widely used in industrial production. Equipment such as fans, motors, and steam turbines are crucial for ensuring smooth production processes. However, during actual operation, rotating equipment is prone to rotational imbalance due to various reasons. This imbalance can lead to a series of serious problems. Severe vibration not only causes high-decibel noise, disrupting the production environment, but also accelerates wear of critical components such as bearings, significantly shortening the equipment's overall service life. In severe cases, it can even cause equipment failure, leading to safety incidents and posing a significant threat to production continuity and personnel safety.

[0003] However, when testing a rotating shaft, the existing dynamic balancing adjustment device moves from one end of the rotating shaft to the other end for detection, and then adjusts the position of the rotating shaft according to the rotating shaft. However, this can only detect the imbalance degree of one end of the rotating shaft, and is not convenient for accurately marking the imbalance area on the surface of the rotating shaft. The rotating shaft needs to be polished and tested multiple times to maintain balance. Moreover, when testing rotating shafts of different specifications, it is not convenient to synchronously adjust the marked area according to the size of the rotating shaft, which may make the position mark of the imbalance area inaccurate, thereby affecting subsequent polishing or counterweight operations, resulting in incomplete dynamic balancing adjustment.

[0004] In response to the above problems, it is urgent to carry out innovative design based on the original foundation. Summary of the Invention

[0041] As an embodiment of the present invention, the number of fixed platforms 9 is two groups, and the two groups of fixed platforms 9 are symmetrically distributed on both sides of the mobile frame 5. A motor is installed on the left side of the mobile frame 5, and a ring is installed on the output end of the motor. A round rod is installed on the side of the fixed platform 9 on the left side of the mobile frame 5 away from the roller 10. The round rod passes through the fixed platform 9 and is connected to the roller 10. A belt is provided on the surface of the round rod and the ring. The motor drives the roller 10 to rotate through the belt, thereby driving the rotating shaft to rotate;

[0042] As an embodiment of the present invention, the clamping assembly includes a mounting ring 151 mounted on the right end of the rotating ring 13, a sliding rod 152 is provided inside the mounting ring 151 for limited sliding, the sliding rod 152 is provided on the surface of the mounting ring 151, a moving ring 154 is provided on the right side surface of the rotating ring 13 for limited sliding in the lateral direction, a third electric push rod 155 is provided on the right side surface of the rotating ring 13, the protruding end of the third electric push rod 155 is connected to the moving ring 154, and a resistance block 156 is provided on the side of the moving ring 154 close to the mounting ring 151. When the balance test of the rotating shaft is performed, the rotating ring 13 can rotate synchronously with the rotating shaft, thereby facilitating the accurate marking of uneven areas on the surface of the rotating shaft.

[0043] As an embodiment of the present invention, there are two groups of sliding rods 152 and interference blocks 156. The two groups of sliding rods 152 and interference blocks 156 are symmetrically distributed on the surface of the rotating ring 13. A pressure block 153 is fixed between the two sliding rods 152 in each group. The top of the pressure block 153 is provided with a rounded corner, and the surface of the interference block 156 is provided with an inclined surface. The inclined surface of the interference block 156 is in contact with the top of the pressure block 153. The extended end of the third electric push rod 155 can be controlled to different lengths according to the size of the transmission shaft, thereby performing different clamping forces according to the size of the rotating shaft. The end clamp of the sliding rod 152 is made of rubber.

[0044] The existing dynamic balancing adjustment device is not convenient for accurately marking the unbalanced area on the surface of the rotating shaft, and when testing rotating shafts of different specifications, it is not convenient to synchronously adjust the marked area according to the size of the rotating shaft. The specific implementation method is as follows. When working, first, the rotating shaft is passed through the swivel 13 and placed on the surface of the roller 10. Then the controller 2 pushes the connecting frame 8 downward through the output end of the first electric push rod 7 so that the transmission shaft is in the middle of the swivel 13. The controller 2 pushes the adjusting rod 11 upward through the output end of the second electric push rod 12 to align the insertion rod with the middle of the transmission shaft. Then, the bolt is rotated to fix the insertion rod to both ends of the rotating shaft. Then, the controller 2 drives the motor to rotate the roller 10 through the belt, and the roller 10 drives the transmission shaft to rotate. At this time, the controller 2 drives the motor to drive the screw to rotate, and the slider 6 moves inside the movable frame 5. When the movable frame 5 moves, the visual sensor 14 inside the swivel 13 detects the surface of the transmission shaft. The visual sensor 14 When it is detected that the surface of the transmission shaft is uneven, the controller 2 drives the motor to stop working. At this time, the controller 2 drives the output end of the third electric push rod 155 to extend, pushing the moving ring 154 to move on the surface of the rotating ring 13. The friction block 156 on the right side of the rotating ring 13 squeezes the pressure block 153, and the pressure block 153 pushes the slide bar 152 to move down inside the mounting ring 151 to clamp the transmission shaft. The transmission shaft drives the rotating ring 13 to rotate inside the connecting frame 8. At this time, the spray head 16 marks the unbalanced area on the surface of the transmission shaft. Then the controller 2 drives the protruding end of the third electric push rod 155 to retract, and the protruding end of the third electric push rod 155 drives the moving ring 154 to move left. The pressure block 153 loses the squeezing of the friction block 156, and the spring drives the slide bar 152 to automatically reset, so that the slide bar 152 leaves the transmission shaft. The controller 2 drives the motor to drive the screw rod to continue to rotate, and continues to detect the rotating shaft. After the detection is completed, the controller 2 drives the electric grinder 4 to grind the marked area on the surface of the transmission shaft;

[0045] As an embodiment of the present invention, a spiral groove is formed inside the sleeve 181, and a protrusion is installed on the surface of the rotating drum 182. The protrusion slides within the spiral groove. When the protrusion slides within the spiral groove, it can drive the rotating drum 182 to rotate at the bottom of the spray head 16, thereby adjusting the spray diameter of the spray head 16.

[0046] As an embodiment of the present invention, the compensation adjustment component includes an oil tank 191 arranged inside the mounting frame on the surface of the swivel 13, the protruding end of the fourth electric push rod 17 passes through the mounting frame and is connected to the top of the oil tank 191, the oil tank 191 has a first piston rod 192 for limited sliding inside the first piston rod 192, the sleeve 181 has an oil tube 193 for limited sliding inside the first piston rod 192, the top of the oil tube 193 is connected to the bottom of the oil tank 191, the oil tube 193 has a second piston rod 194 for limited sliding inside the second piston rod 194, and a hose is connected between the oil tube 193 and the oil tank 191. Through the compensation adjustment component, the caliber of the spray head 16 can be readjusted according to the unevenness of the rotating shaft surface. There may be local protrusions, depressions or irregular areas on the rotating shaft surface. The compensation adjustment component can adjust the caliber of the spray head 16 in real time according to these unevenness.

[0047] Working principle: When working, first pass the rotating shaft through the swivel 13 and place it on the surface of the roller 10. Then the controller 2 pushes the connecting frame 8 downward through the output end of the first electric push rod 7 so that the transmission shaft is in the middle of the swivel 13. The controller 2 pushes the adjusting rod 11 upward through the output end of the second electric push rod 12 to align the insertion rod with the middle of the transmission shaft. Then the bolt is turned to fix the insertion rod to both ends of the rotating shaft. Then the controller 2 drives the motor to rotate the roller 10 through the belt, and the roller 10 drives the transmission shaft to rotate. At this time, the controller 2 drives the motor to drive the screw to rotate, and the slider 6 moves inside the mobile frame 5. When the mobile frame 5 moves, the visual sensor 14 inside the swivel 13 detects the surface of the transmission shaft. When the visual sensor 14 detects that the surface of the transmission shaft is uneven, the controller 2 drives the motor to stop working. At this time, the controller 2 drives the third electric push rod The output end of the push rod 155 extends to push the moving ring 154 to move on the surface of the rotating ring 13. The friction block 156 on the right side of the rotating ring 13 squeezes the pressure block 153. The pressure block 153 pushes the slide bar 152 to move down inside the mounting ring 151 to clamp the transmission shaft. The transmission shaft drives the rotating ring 13 to rotate inside the connecting frame 8. At this time, the spray head 16 marks the unbalanced area on the surface of the transmission shaft. Then the controller 2 drives the extended end of the third electric push rod 155 to retract. The extended end of the third electric push rod 155 drives the moving ring 154 to move left. The pressure block 153 loses the squeezing of the friction block 156. The spring drives the slide bar 152 to automatically reset, so that the slide bar 152 leaves the transmission shaft. The controller 2 drives the motor to drive the screw rod to continue to rotate and continue to detect the rotating shaft. After the detection is completed, the controller 2 drives the electric grinder 4 to grind the marked area on the surface of the transmission shaft.

[0048] When processing a smaller drive shaft, the controller 2 drives the output end of the fourth electric push rod 17 to push the spray head 16 to move inside the swivel 13 through the oil tank 191. When the spray head 16 moves inside the swivel 13, it drives the rotating cylinder 182 to slide within the sleeve 181, so that the rotating cylinder 182 rotates counterclockwise at the bottom of the spray head 16. The rotating cylinder 182 drives the slide plate 184 to slide within the internal groove of the first adjusting plate 183 through the second adjusting plate 185. The slide plate 184 blocks the spray outlet of the spray head 16, so that the marking area of ​​the spray head 16 on the drive shaft surface is reduced. When the controller 2 drives the output end of the fourth electric push rod 17 to drive the oil tank 191 to descend, the oil tank 191 drives the oil pipe 193 to move downward synchronously. The bottom of the second piston rod 194 contacts the surface of the transmission shaft. When the roller 10 drives the transmission shaft to rotate, the second piston rod 194 is resisted by the protrusion on the surface of the transmission shaft. The second piston rod 194 slides toward the inside of the oil pipe 193, and the oil inside the oil pipe 193 is injected into the oil tank 191. The increase in the oil inside the oil tank 191 causes the first piston rod 192 to contract, driving the spray head 16 to move toward the outside of the swivel 13, so that the rotating cylinder 182 rotates clockwise at the bottom of the spray head 16. The rotating cylinder 182 drives the slide plate 184 to slide in the internal groove of the first adjusting plate 183 through the second adjusting plate 185. The slide plate 184 opens the spray outlet of the spray head 16 appropriately, so that the spray head 16 can synchronously adjust the marked area on the surface of the transmission shaft.
