Description

Technical Field

[0001] The present application relates to the field of rotor balancing and correction, and in particular to a dustproof component of a motor rotor balancing machine. Background Art

[0002] The motor rotor is affected by materials, manufacturing processes and assembly processes during its manufacturing process, resulting in an initial imbalance. Based on this, after the motor rotor is processed, workers usually test and correct the imbalance of the motor rotor to ensure product quality.

[0003] In the prior art, the correction of the motor rotor is sometimes achieved by laser de-weighting, that is, using laser to irradiate the unbalanced position of the rotor to remove the excess weight on the rotor. However, during the laser irradiation process, a lot of dust will fall on the rotor, which will seriously affect the environment of the external production workshop. Utility Model Content

[0004] In order to overcome the deficiencies of the prior art, the present application provides a dustproof component for a motor rotor balancing machine.

[0005] The dustproof component of a motor rotor balancing machine provided in the present application adopts the following technical solution:

[0006] A dustproof component of a motor rotor balancing machine includes a bracket, a dust cover and at least two lifting units, each of the lifting units includes a lifting rod that can be lifted and lowered and is arranged on the bracket, and a transmission module for driving the lifting rod to lift and lower, and at least two ends of the lifting rods in the same direction are respectively connected to the side of the dust cover, and the dustproof component also includes a driving module for driving at least two of the transmission modules to operate synchronously.

[0007] By adopting the above technical solution, when the rotor is in the correction process, the dust cover descends and covers the circumference of the rotor, which can effectively prevent dust from leaking out and affecting the environment of the external production workshop; when the rotor is outside the correction process, the dust cover rises, which is convenient for workers to take and place the rotor, thereby improving work efficiency; at the same time, at least two transmission modules running synchronously can ensure that the circumferential side of the dust cover rises and falls synchronously, ensuring the dust-proof effect of the dust cover.

[0008] In a specific implementation scheme, there are two lifting units and they are respectively located on both sides of the dust cover. The two lifting rods are parallel to each other and extend in the vertical direction respectively. The opposite sides of the dust cover are respectively connected to the lower ends of the two lifting rods.

[0009] By adopting the above technical solution, the dust cover can have a sufficient lifting stroke to avoid the dust cover affecting workers in taking and placing the rotor.

[0010] In a specific possible implementation scheme, each of the lifting rods includes a rod body and a rack arranged on the side of the rod body, the extension direction of the rack is consistent with the extension direction of the rod body, the serrations of the two racks are in opposite directions, and each of the transmission modules includes a first gear meshed with the rack.

[0011] By adopting the above technical solution, it is possible to effectively avoid interference between the dust cover and the first gear during the lifting process.

[0012] In a specific possible implementation manner, a relief end is provided at the lower end of the rod body, and the width of the relief end gradually decreases along the vertical downward direction.

[0013] By adopting the above technical solution, when the dust cover descends, the avoidance end with a gradually decreasing width can effectively prevent the rod body from colliding with other components on the peripheral side of the rotor.

[0014] In a specific possible implementation mode, each of the transmission modules further includes a transmission wheel disposed on the bracket for driving the first gear to rotate, the two transmission wheels are connected via a synchronous belt transmission, and the driving module is used to drive at least one transmission wheel to rotate.

[0015] In a specific possible implementation scheme, the dustproof component also includes a tensioning module, which includes an adjustment slot opened on the bracket and extending in a vertical direction, an adjustment block movably arranged in the adjustment slot, and a tensioning wheel rotatably arranged on the adjustment block, and the wheel surface of the tensioning wheel is in conflict with the synchronous belt.

[0016] By adopting the above technical solution, the synchronous belt can be effectively tensioned to improve the synchronization of the two transmission wheels.

[0017] In a specific feasible implementation scheme, each of the transmission modules also includes a first transmission shaft at one end coaxially connected to the first gear, the two first transmission shafts are parallel to each other and extend in the horizontal direction respectively, the two transmission wheels include a driving wheel and a driven wheel, the driving module is used to drive the driving wheel to rotate, a second transmission shaft is coaxially connected to the driving wheel, the other end of one of the two first transmission shafts is coaxially connected to the driven wheel, the other end of the other one is provided with a second gear, the second transmission shaft is provided with a third gear, and the second gear is meshed with the third gear.

[0018] By adopting the above technical solution, not only can the synchronous lifting of the two lifting rods be ensured, but also the interference between the lifting rods and the bracket during the lifting process can be effectively avoided.

[0019] In a specific possible implementation scheme, each of the lifting units further comprises a fixing frame, and fixing seats are respectively arranged at both ends of the fixing frame, and both ends of the first transmission shaft are rotatably connected to the two fixing seats respectively.

[0020] By adopting the above technical solution, the transmission stability of the first transmission shaft can be effectively improved.

[0021] In a specific possible implementation mode, a guide rail is provided on the fixing frame, the guide rail extends along the vertical direction, and the lifting rod is slidably connected to the guide rail.

[0022] By adopting the above technical solution, the lifting stability of the lifting rod can be effectively improved.

[0023] In a specific feasible implementation scheme, the bracket includes at least two upright support rods and a mounting base supported on the upper ends of the at least two support rods, the at least two lifting units are arranged on the mounting base, and the dust cover is located below the mounting base.

[0024] In summary, the present application includes at least one of the following beneficial technical effects:

[0025] 1. When the rotor is in the calibration process, the dust cover is lowered and placed around the rotor, which can effectively prevent dust from leaking out and affecting the environment of the external production workshop;

[0026] 2. When the rotor is out of the calibration process, the dust cover rises, making it easier for workers to take and put the rotor, thus improving work efficiency;

[0027] 3. At least two transmission modules running synchronously can ensure that the peripheral side of the dust cover rises and falls synchronously, thereby ensuring the dustproof effect of the dust cover. BRIEF DESCRIPTION OF THE DRAWINGS

[0032] The present application is further described in detail below in conjunction with the accompanying drawings.

[0033] See also Figure 1-2 As shown, a dustproof component of a motor rotor balancing machine is shown, including a bracket 1, a dust cover 2 and two lifting units 3. The bracket 1 includes two upright support rods 11, a mounting seat 12 supported on the upper ends of the two support rods 11, the mounting seat 12 is horizontally arranged, the two lifting units 3 are respectively arranged at both ends of the mounting seat 12 in the length direction, and the dust cover 2 is located below the mounting seat 12.

[0034] Each lifting unit 3 includes a lifting rod 31 that can be lifted and lowered and is arranged on the side of the mounting seat 12, and a transmission module 32 for driving the lifting rod 31 to lift and lower. The ends of the two lifting rods 31 in the same direction are respectively connected to the side of the dust cover 2. The dustproof component also includes a driving module 33 for driving at least two transmission modules 32 to operate synchronously.

[0035] When the rotor is in the calibration process, the dust cover 2 descends and covers the side of the rotor, which can effectively prevent dust from leaking out and affecting the environment of the external production workshop; when the rotor is outside the calibration process, the dust cover 2 rises, which is convenient for workers to take and place the rotor, thereby improving work efficiency; at the same time, the two synchronously running transmission modules 32 can ensure that the two sides of the dust cover 2 rise and fall synchronously, ensuring the dust-proof effect of the dust cover 2.

[0036] In this embodiment, two lifting units 3 are symmetrically located on both sides of the dust cover 2, two lifting rods 31 are parallel to each other and extend in the vertical direction, and the opposite sides of the dust cover 2 are respectively connected to the lower ends of the two lifting rods 31. In this way, the dust cover 2 can have a sufficient lifting stroke to prevent the dust cover 2 from affecting the workers' taking and placing of the rotor.

[0037] In this embodiment, each lifting rod 31 includes a rod body 311 and a rack 312 arranged on the side of the rod body 311. The extension direction of the rack 312 is consistent with the extension direction of the rod body 311. The serrations of the two racks 312 are in opposite directions. Each transmission module 32 includes a first gear 321 meshed with the rack 312, and a transmission wheel 322 arranged at the end of the mounting seat 12 for driving the first gear 321 to rotate. The two transmission wheels 322 are connected by a synchronous belt 4. The driving module 33 is a motor, which is used to drive one of the transmission wheels 322 to rotate.

[0038] Each transmission module 32 also includes a first transmission shaft 323 having one end coaxially connected to the first gear 321. The two first transmission shafts 323 are parallel to each other and extend in the horizontal direction respectively. The two transmission wheels 322 include a driving wheel 3221 and a driven wheel 3222. The driving module 33 is used to drive the driving wheel 3221 to rotate. The driving wheel 3221 is coaxially connected to a second transmission shaft (not shown in the figure). The other end of one of the two first transmission shafts 323 is coaxially connected to the driven wheel 3222, and the other end of the other one is sleeved with a second gear 324. The second transmission shaft is sleeved with a third gear 325, and the second gear 324 is meshed with the third gear 325.

[0039] Through the above configuration, not only can the dust cover 2 be effectively prevented from interfering with the first gear 321 during the lifting process, but also due to the configuration of the first transmission shaft 323, the rack 312 can be kept away from the mounting seat 12, effectively preventing the lifting rod 31 from interfering with the mounting seat 12 during the lifting process.

[0040] In this embodiment, the lower end of the rod body 311 is provided with an escape end 313, and the width of the escape end 313 gradually decreases along the vertical downward direction. When the dust cover 2 descends, the gradually decreasing escape end 313 can effectively prevent the rod body 311 from colliding with other parts around the rotor.

[0041] The dustproof assembly also includes a tensioning module 5, which includes an adjustment slot 51 provided on the mounting seat 12 and extending in the vertical direction, an adjustment block 52 movably provided in the adjustment slot 51, and a tensioning wheel 53 rotatably provided on the adjustment block 52, wherein the wheel surface of the tensioning wheel 53 is in conflict with the synchronous belt 4. The tensioning wheel 53 can effectively tension the synchronous belt 4 and improve the synchronization of the two transmission wheels 322. Among them, a wheel axle (not shown in the figure) is inserted into the adjustment block 52, and the tensioning wheel 53 is rotatably connected to the adjustment block 52 through the wheel axle, and a locking nut (not shown in the figure) for locking the adjustment block 52 is also sleeved on the end of the wheel axle away from the tensioning wheel 53.

[0042] In this embodiment, each lifting unit 3 further includes a horizontally arranged fixing frame 34, the length direction of the fixing frame 34 is perpendicular to the length direction of the mounting seat 12, and fixing seats 35 are respectively arranged at both ends of the fixing frame 34, and both ends of the first transmission shaft 323 are respectively rotatably connected to the two fixing seats 35. The fixing seats 35 can effectively improve the transmission stability of the first transmission shaft 323.

[0043] A guide rail 36 is also provided at the end of the fixing frame 34. The guide rail 36 extends in the vertical direction, and the lifting rod 31 is slidably connected to the guide rail 36. The guide rail 36 can effectively improve the lifting stability of the lifting rod 31.

[0044] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
