Description

Technical Field

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

[0002] In the field of industrial production, rotating equipment is widely used. Equipment such as fans, motors, and steam turbines are the key to ensuring the smooth operation of the production process. However, during the actual operation, rotating equipment is very likely to have unbalanced rotation due to various reasons. When the equipment rotates unbalanced, it will cause a series of serious problems. The violent vibration will not only cause the equipment to produce high-decibel noise and interfere with the production environment, but also accelerate the wear of key components such as bearings inside the equipment, greatly shortening the overall service life of the equipment. In serious cases, it may even cause equipment failure, resulting in safety accidents, posing a major threat to production continuity and personnel safety.

[0003] However, when testing the 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 it is not convenient to accurately mark the unbalanced area on the surface of the rotating shaft. The rotating shaft needs to be polished and tested many 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 unbalanced area inaccurate, thereby affecting the subsequent polishing or counterweight operation, 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 basis. Summary of the invention

[0015] Compared with the prior art, the beneficial effects of the present invention are as follows: In the present invention, through the arranged clamping assembly, connecting frame, fixed table and rotating ring, when performing a balance detection on the rotating shaft, the rotating ring can rotate synchronously with the rotating shaft, so as to facilitate accurately marking the uneven areas on the surface of the rotating shaft. The rotating ring rotates synchronously with the rotating shaft, and can mark the uneven areas on the surface of the rotating shaft in real time and accurately, avoiding multiple grindings and detections by the operator due to inaccurate marking, thus significantly improving the efficiency of dynamic balance adjustment.

When the size of the rotating shaft is large, the caliber of the spraying head increases accordingly to ensure that the marking range can completely cover the surface of the shaft body, avoiding incomplete marking or repeated coating due to too small a spraying head. When the size of the rotating shaft is small, the caliber of the spraying head shrinks synchronously, making the marking more concentrated and clear, avoiding blurred marking or exceeding the effective area, thereby improving the accuracy of the marking.

[0017] In the present invention, through the provided compensation adjustment component, the diameter of the spray head can be adjusted again according to the unevenness of the surface of the rotating shaft. There may be local protrusions, depressions or irregular areas on the surface of the rotating shaft, and the compensation adjustment component can adjust the diameter of the spray head in real time according to these unevennesses, so that the spraying mark can fit the actual uneven position more precisely, avoiding the marking deviation caused by the fixed diameter of the spray head.

An adjusting rod 11 is limitedly slid in a connecting block on the side of the fixed platform 9 away from the roller 10, and a second electric push rod 12 is installed at the top of the connecting block. The extended end of the second electric push rod 12 is connected to the adjusting rod 11, and a bolt is threadedly connected inside the adjusting rod 11, and a plug rod is rotatably connected to the end of the bolt; As an embodiment of the present invention, there are two groups of fixed platforms 9, which 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 penetrates the fixed platform 9 and is connected to the roller 10. A belt is sleeved on the surface of the round rod and the ring. The motor drives the roller 10 to rotate through the belt, and drives the rotating shaft to rotate; 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, a 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 extended 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, so that the rotating ring 13 can rotate synchronously with the rotating shaft when the balance detection of the rotating shaft is performed, so as to facilitate the accurate marking of the uneven area on the surface of the rotating shaft; As an embodiment of the present invention, there are two groups of slide bars 152 and abutment blocks 156, which are symmetrically distributed on the surface of the rotating ring 13. A pressure block 153 is fixed between each group of two slide bars 152. The top of the pressure block 153 is provided with a rounded corner, and the surface of the abutment block 156 is provided with an inclined surface. The inclined surface of the abutment 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 according to the size of the transmission shaft to extend to different lengths, so as to clamp with different strengths according to the size of the rotating shaft. The end clamp of the slide bar 152 is made of rubber. The existing dynamic balance adjustment device is not convenient for accurately marking the unbalanced area on the surface of the rotating shaft, and it is not convenient to synchronously adjust the marking area according to the size of the rotating shaft when testing rotating shafts of different specifications. The specific implementation method is as follows. During operation, first place the rotating shaft through the rotating ring 13 on the surface of the rotating roller 10. Subsequently, the controller 2 drives the connecting frame 8 to move downward through the output end of the first electric push rod 7, so that the transmission shaft is located in the middle of the rotating ring 13. The controller 2 drives the adjusting rod 11 to move 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 rotate the bolt to fix the insertion rod to both ends of the rotating shaft. Subsequently, the controller 2 drives the motor to drive the rotating roller 10 to rotate through the belt, and the rotating roller 10 drives the transmission shaft to rotate. At this time, the controller 2 drives the motor to drive the lead screw to rotate, and the slider 6 moves inside the moving frame 5. When the moving frame 5 moves, the visual sensor 14 inside the rotating ring 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 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 contact block 156 on the right side of the rotating ring 13 squeezes the pressing block 153, and the pressing block 153 pushes the sliding rod 152 to move downward 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 spraying head 16 marks the unbalanced area on the surface of the transmission shaft. Subsequently, 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 leftward, and the pressing block 153 loses the extrusion of the contact block 156. The spring drives the sliding rod 152 to automatically reset, so that the sliding rod 152 leaves the transmission shaft. The controller 2 drives the motor to drive the lead screw to continue rotating to continue detecting the rotating shaft. After the detection is completed, the controller 2 drives the electric grinding machine 4 to grind the marked area on the surface of the transmission shaft; As an implementation manner of the present invention, a spiral groove is provided inside the sleeve 181, and a convex block is installed on the surface of the rotating cylinder 182. The convex block is limited to slide in the spiral groove. When the convex block is limited to slide in the spiral groove, it can drive the rotating cylinder 182 to rotate at the bottom of the spraying head 16, thereby adjusting the spraying diameter of the spraying head 16; As an embodiment of the present invention, the compensation and adjustment assembly includes an oil tank 191 disposed inside the mounting frame on the surface of the swivel 13. The extending end of the fourth electric push rod 17 penetrates through the mounting frame and is connected to the top end of the oil tank 191. A first piston rod 192 is slidably limited inside the oil tank 191. An oil pipe 193 is slidably limited inside the sleeve 181. The top end of the oil pipe 193 is connected to the bottom of the oil tank 191. A second piston rod 194 is slidably limited inside the oil pipe 193. A hose is connected between the oil pipe 193 and the oil tank 191. By providing the compensation and adjustment assembly, the diameter of the spray head 16 can be adjusted again according to the unevenness of the surface of the rotating shaft. There may be local protrusions, depressions or irregular regions on the surface of the rotating shaft, and the compensation and adjustment assembly can adjust the diameter of the spray head 16 in real time according to these unevennesses.

[0023] Working principle: During operation, first place the rotating shaft through the swivel 13 on the surface of the rotating roller 10. Subsequently, the controller 2 drives the output end of the first electric push rod 7 to push the connecting frame 8 downward, so that the transmission shaft is located in the middle of the swivel 13. The controller 2 drives the output end of the second electric push rod 12 to push the adjusting rod 11 upward so that the insertion rod is aligned with the middle of the transmission shaft. Then rotate the bolt to fix the insertion rod to both ends of the rotating shaft. Subsequently, the controller 2 drives the motor to drive the rotating roller 10 to rotate through the belt. The rotating roller 10 drives the transmission shaft to rotate. At this time, the controller 2 drives the motor to drive the lead screw to rotate, and the slider 6 moves inside the moving frame 5. When the moving 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 output end of the third electric push rod 155 to extend, pushing the moving ring 154 to move on the surface of the swivel 13. The contact block 156 on the right side of the swivel 13 squeezes the pressing block 153. The pressing block 153 pushes the sliding rod 152 to move downward inside the mounting ring 151 to clamp the transmission shaft. The transmission shaft drives the swivel 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. Subsequently, the controller 2 drives the extending end of the third electric push rod 155 to retract. The extending end of the third electric push rod 155 drives the moving ring 154 to move leftward. The pressing block 153 loses the extrusion of the contact block 156, and the spring drives the sliding rod 152 to automatically reset, so that the sliding rod 152 leaves the transmission shaft. The controller 2 drives the motor to drive the lead screw to continue rotating to continue detecting the rotating shaft. After the detection is completed, the controller 2 drives the electric grinding machine 4 to grind the marked area on the surface of the transmission shaft; When machining a transmission shaft with a relatively small size, the controller 2 drives the output end of the fourth electric push rod 17 to push the spraying head 16 into the inside of the rotating ring 13 through the oil tank 191. When the spraying head 16 moves into the inside of the rotating ring 13, it drives the rotating cylinder 182 to slide in a limited manner inside the sleeve 181, causing the rotating cylinder 182 to rotate counterclockwise at the bottom of the spraying head 16. The rotating cylinder 182 drives the sliding plate 184 to slide in a limited manner inside the chute of the first adjusting plate 183 through the second adjusting plate 185. The sliding plate 184 blocks the spraying outlet of the spraying head 16, reducing the marked area on the surface of the transmission shaft by the spraying head 16. While 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, causing the bottom of the second piston rod 194 to contact the surface of the transmission shaft. When the rotating roller 10 drives the transmission shaft to rotate, at this time, the second piston rod 194 is resisted by the protrusions on the surface of the transmission shaft, and the second piston rod 194 slides into the oil pipe 193, injecting the oil inside the oil pipe 193 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 spraying head 16 to move outside the rotating ring 13, causing the rotating cylinder 182 to rotate clockwise at the bottom of the spraying head 16. The rotating cylinder 182 drives the sliding plate 184 to slide in a limited manner inside the chute of the first adjusting plate 183 through the second adjusting plate 185. The sliding plate 184 appropriately opens the spraying outlet of the spraying head 16, synchronously adjusting the marked area on the surface of the transmission shaft by the spraying head 16.
