Description

Technical Field

[0001] The present application relates to the field of dynamic balancing testing, and in particular to a dynamic balancing adjustment device and an adjustment process. Background Art

[0002] A rotor is a rotating object supported by bearings or an object without its own axis of rotation, such as a compact disc. When it rotates with a rigid connection or an additional shaft, it can be considered a rotor. Rotors are often the main rotating components in power machinery and working machinery.

[0003] Rotor vibration has become a prominent technical issue in rotating machines and parts, significantly impacting machine life, reliability, operational performance, and machining accuracy. Material unevenness, machining and installation errors, and the rotor's inherent structure are the primary sources of rotor imbalance and vibration.

[0004] In order to solve the problem that the rotor is prone to rotor imbalance and rotor rotation during rotation, a dynamic balancing detection device is currently used to perform dynamic balancing detection on the rotor before the rotor is actually put into use. The dynamic balancing detection device includes a base, on which is provided a clamp that is rotatably connected to the end of the rotor. The base is also provided with a driving mechanism for driving the rotor. The driving mechanism can perform dynamic balancing detection when driving the rotor to rotate.

[0005] When the above-mentioned dynamic balancing detection device is used to detect the terminal, the fixture needs to be disassembled and adjusted multiple times for rotors of different models and sizes, which is inconvenient and needs to be improved. Summary of the Invention

[0006] In order to improve the problem in the related art that a dynamic balance detection device needs to adjust the fixture multiple times during the dynamic balance detection process, the present application provides a dynamic balance adjustment device and an adjustment process.

[0007] In the first aspect, the present application provides a dynamic balancing adjustment device and an adjustment process using the following technical solutions:

[0008] A dynamic balancing adjustment device includes a base, a mounting frame for placing one end of a rotor is provided on the base, a driving mechanism for driving the rotor is provided on the base, a slide is provided on the base, a clamp is provided on the slide, the clamp and the mounting frame are arranged on both sides of the rotor, a sliding plate is provided on the base, a sliding groove is provided on the slide, the sliding plate is inserted in the sliding groove, the slide moves toward or away from the mounting frame on the sliding plate through the sliding groove, and a fixing structure for fixing the slide is provided on the slide.

[0009] By adopting the above technical solution, when the dynamic balancing adjustment device in this application is used to perform a dynamic balancing test on the rotor, the operator can change the distance between the slide and the mounting frame by adjusting the slide, so that when rotors of different sizes need to be dynamically balanced, the dynamic balancing adjustment device in this application can adapt to rotors of various models without the need to disassemble or replace the fixture. Compared with the dynamic balancing detection device in the related art, the dynamic balancing adjustment device in this application has a wider range of applications and is easier to operate, which improves the convenience of dynamic balancing detection of the rotor.

[0010] Optionally, the fixing structure includes a locking screw and a locking knob, a locking hole is opened on the side wall of the sliding seat, the locking screw is threadedly inserted into the locking hole, one end of the locking screw inserted into the locking hole is against the sliding plate, and the locking knob is arranged at the end of the locking screw away from the sliding plate.

[0011] By adopting the above technical solution, when performing dynamic balancing test on the rotor, the operator needs to fix the slide. At this time, the locking screw can be rotated so that the end of the locking screw inserted into the locking hole is against the sliding plate, so that the locking screw can drive the slide to be locked through the friction between the locking screw and the sliding plate, so that the slide is relatively stable when the dynamic balancing test of the rotor is performed, reducing the possibility of errors in the test results due to slide slippage or even the possibility of the rotor falling off and being damaged.

[0012] Optionally, the fixed structure includes a sliding motor, a sliding gear and a sliding rack, the sliding motor is arranged on the top of the sliding seat, the output end of the sliding motor is connected to the sliding gear, the sliding rack is arranged on the top side wall of the sliding plate, and the sliding gear is meshed with the sliding rack.

[0013] By adopting the above technical solution, when the position of the slide is adjusted by using the structure of the sliding motor and the sliding gear, the operator can turn on the sliding motor so that the sliding motor drives the sliding gear to rotate. Since the sliding gear is engaged with the sliding rack, and the sliding rack is fixedly connected to the sliding plate, the sliding gear moves on the sliding rack at this time, thereby driving the slide to move on the sliding plate. When the sliding motor stops working, the sliding gear cannot be rotated, so the sliding of the slide and the fixation of the position can be achieved, thereby improving the convenience of the operator.

[0014] Optionally, the clamp includes a connecting seat and a rotating seat, the connecting seat is detachably connected to the sliding seat, the rotating seat is arranged on the top of the connecting seat, and the rotating seat is rotatably connected to the rotor.

[0015] By adopting the above technical solution, through the detachable connection structure between the connecting seat and the sliding seat, the fixture can be replaced to quickly adapt the end of the rotor when performing dynamic balancing tests on rotors with different shaft diameters, thereby improving the convenience of operators when testing rotors with different axis centers.

[0016] Optionally, a rotating hole is provided on the rotating seat for inserting one end of the rotor, and an abutment spring is provided on the top side wall of the rotating hole. One end of the abutment spring is connected to the inner side wall of the rotating hole, and the other end is provided with an abutment block, which abuts against the side wall of one end of the rotor.

[0017] By adopting the above technical solution, if the balance test is performed on rotors with different shaft diameters, and the shaft diameter variation range of these rotors is small, there is no need to frequently replace the fixture. It is only necessary to use the abutment spring to abut the abutment block against the shaft side wall of the rotor. On the one hand, this improves the convenience of detection, and on the other hand, it reduces the possibility of excessive rotor vibration frequency caused by the mismatch between the rotating hole and the rotor shaft diameter.

[0018] Optionally, an anti-torsion rod is provided on the inner side wall of the rotating hole, the anti-torsion rod is inserted into the abutment spring, an anti-torsion hole is opened on the side wall of the abutment block close to the anti-torsion rod, and the anti-torsion rod is slidably connected to the anti-torsion hole.

[0019] By adopting the above technical solution, when the structure of the abutment spring and the abutment block is used to abut one end of the rotor, when the rotor is dynamically balanced, the rotor will rotate rapidly. At this time, due to the friction between the side wall of the rotor shaft and the abutment block, the abutment block is likely to move perpendicular to the elastic direction of the abutment spring. At this time, the abutment spring is prone to distortion. The structure of the anti-torsion rod and the anti-torsion hole reduces the possibility of distortion of the abutment spring, thereby improving the stability of the system.

[0020] Optionally, when the abutment block abuts against the inner side wall of the rotating hole, the abutment spring is in a compressed state.

[0021] By adopting the above technical solution, when the abutment block abuts against the inner wall of the rotating hole, the rotor shaft is not inserted into the rotating hole. At this time, if the abutment spring is in a compressed state, when the rotor shaft is inserted into the rotating hole, the abutment spring always remains in a compressed state, thereby pushing the abutment block to abut against the rotor shaft, thereby improving the stability of the rotor during the dynamic balancing test.

[0022] Optionally, the driving mechanism includes a driving motor, a transmission belt and a driving bracket, the driving motor is arranged on the base, the transmission belt is wound around the output end of the driving motor, the transmission belt is abutted against the side wall of the rotor, the driving bracket is arranged on the base, a driving wheel is provided on the driving bracket, and the transmission belt is wound around the driving wheel.

[0023] By adopting the above-mentioned technical solution and the structure of a drive motor and a drive wheel, when the driving mechanism in this application drives the rotor to rotate, the transmission belt can be controlled by the drive motor. Since the transmission belt and the rotor are fitted together and there is a large friction between the transmission belt and the rotor, the transmission belt can drive the rotor to rotate, so as to more conveniently realize the dynamic balance test of the rotor.

[0024] Optionally, an adjustment slot is provided on the driving bracket, the adjustment slot is vertically arranged, a fixing rod is provided on the inner wall of the driving wheel close to the adjustment slot, a fixing nut is threadedly sleeved on the fixing rod, and the fixing nut is against the side wall of the driving bracket away from the driving wheel.

[0025] By adopting the above technical solution and the structure of the adjustment slot, the driving wheel can be moved in the vertical direction on the driving bracket through the adjustment slot. Therefore, when the shaft diameter of the rotor is large, the position of the driving wheel can be adjusted to keep the friction between the transmission belt and the rotor within a certain range, thereby reducing the possibility of excessive wear of the transmission belt during rotation due to excessive friction between the transmission belt and the rotor, and extending the service life of the system.

[0026] In a second aspect, the present application provides a dynamic balancing adjustment device and an adjustment process, which adopt the following technical solutions:

[0027] A dynamic balancing adjustment process, applied to a dynamic balancing adjustment device, comprises the following steps:

[0028] Measure the size of the rotor to be tested;

[0029] Adjust the position of the slide based on the size of the rotor to be measured and fix the slide;

[0030] Adjust the driving wheel height;

[0031] The driving mechanism is started to rotate the rotor to obtain dynamic balance information of the rotor.

[0032] By adopting the above technical solution, when the dynamic balancing adjustment process in this application is used to perform a dynamic balancing test on the rotor, the position of the slide can be adjusted according to the size of the rotor first, and then the position of the slide can be fixed by a fixed structure, and the rotor can be set on the driving mechanism so that the driving mechanism drives the rotor to rotate to measure and obtain the dynamic balancing information of the rotor. When the size of the rotor changes, it is only necessary to loosen the fixing structure and adjust the position of the slide, so that the system can be used to test the dynamic balancing information of rotors of different sizes, thereby improving the convenience of the system during testing.

[0033] In summary, this application has at least one of the following beneficial effects:

[0034] 1. The dynamic balancing device of the present application uses a slide and a fixed structure. When the dynamic balancing device of the present application performs a dynamic balancing test on the rotor, the operator can change the distance between the slide and the mounting frame by adjusting the slide. Therefore, when rotors of different sizes need to be dynamically balanced, the dynamic balancing device of the present application can adapt to rotors of various models without having to disassemble or replace the fixture. Compared with the dynamic balancing detection device in the related art, the dynamic balancing device of the present application has a wider range of applications and is easier to operate, thereby improving the convenience of dynamic balancing detection of rotors.

[0035] 2. The locking screw and sliding plate structure is adopted. When the dynamic balancing test of the rotor is carried out, the operator needs to fix the slide. At this time, the locking screw can be rotated so that the end of the locking screw inserted into the locking hole abuts against the sliding plate. The friction between the locking screw and the sliding plate allows the locking screw to drive the slide to be locked. As a result, the slide is more stable during the dynamic balancing test of the rotor, reducing the possibility of errors in the test results or even rotor shedding and damage caused by slide slippage.

[0036] 3. The structure of abutment spring and abutment block is adopted. When the abutment spring and abutment block abut against one end of the rotor, when the rotor is dynamically balanced, the rotor will rotate rapidly. At this time, due to the friction between the side wall of the rotor shaft and the abutment block, the abutment block is prone to move perpendicular to the elastic direction of the abutment spring. At this time, the abutment spring is prone to twisting. The structure of the anti-torsion rod and the anti-torsion hole reduces the possibility of twisting of the abutment spring, thereby improving the stability of the system.

[0046] Reference Figure 1 and Figure 2The fixing structure 2 is arranged on the sliding seat 13 and used for fixing the sliding seat 13 on the sliding plate 16, and the fixing structure 2 can also be used for fixing the mounting frame 11 on the sliding plate 16 (i.e. the fixing mode of the bottom position of the mounting frame 11 is the same as that of the bottom of the sliding seat 13, and thus is not described herein again); the fixing structure 2 comprises a locking screw 21 and a locking knob 22; a locking hole 23 is arranged on the side wall of the sliding seat 13 in a direction perpendicular to the sliding direction of the sliding plate 16, and the locking hole 23 is in communication with the sliding groove 15 and is a threaded hole; the locking screw 21 is inserted into the locking hole 23 and is in threaded connection with the locking hole 23; and the locking knob 22 is integrally formed on one end of the locking screw 21 away from the sliding plate 16, and the locking knob 22 can be held to drive the locking screw 21 to rotate in the locking hole 23, so that the locking screw 21 is abutted against the sliding plate 16, and the sliding seat 13 is fixed.

[0047] With reference to Figure 1 and Figure 2 , the base 1 is provided with a driving mechanism 6, the driving mechanism 6 comprises a driving support 63, a transmission belt 62 and a driving motor 61, the driving motor 61 is mounted on the base 1, an engaging wheel is mounted on the output end of the driving motor 61, the transmission belt 62 is wound on the engaging wheel, and when the driving motor 61 is started to drive the engaging wheel to rotate, the transmission belt 62 is driven by the engaging wheel to transmit power. The driving support 63 is provided in pairs, and each of the pair of driving supports 63 is welded and fixed to the top of the base 1. The line connecting the pair of driving supports 63 is perpendicular to the line connecting the mounting frame 11 and the sliding seat 13. An adjusting groove 7 is formed through the side wall of the pair of driving supports 63 close to the sliding seat 13 along the length direction of the sliding plate 16. A fixing rod 71 is inserted into the adjusting groove 7. The side wall of the fixing rod 71 abuts against the inner side wall of the adjusting groove 7. A driving wheel 64 is welded and fixed to one end of the fixing rod 71. The transmission belt 62 is sleeved on the driving wheel 64. A fixing nut 72 is threadedly connected to the end of the fixing rod 71 away from the driving wheel 64. The fixing nut 72 abuts against the side wall of the driving support 63 by rotating the fixing nut 72, so as to adjust the height of the driving wheel 64.

[0048] With reference to Figure 1 When the dynamic balance test of the rotor 12 needs to be performed, the two ends of the shaft of the rotor 12 are respectively arranged on the mounting frame 11 and the sliding seat 13, and the body of the rotor 12 is arranged on the transmission belt 62. The transmission belt 62 is made of nylon material, and thus the surface of the transmission belt 62 is rough.

The abutting spring 41 is inserted with an anti-torsion rod 5, and one end of the anti-torsion rod 5 away from the abutting block 42 is welded and fixed with the inner side wall of the rotating hole 4; the side wall of the abutting block 42 near the anti-torsion rod is provided with an anti-torsion hole 51, and one end of the anti-torsion rod 5 near the anti-torsion hole 51 is always inserted into the anti-torsion hole 51, and the anti-torsion rod is slidingly connected with the anti-torsion hole 51.
