Description

Technical Field

[0001] This utility model relates to the field of motor rotor cleaning, and in particular to a cleaning bracket for motor rotors. Background Technology

[0002] The motor rotor is the rotating part of the motor, located inside the stator. It is usually composed of a stacked silicon steel core, rotor shaft, conductive components, etc. It rotates under the action of electromagnetic force in the alternating magnetic field generated by the stator, converting electromagnetic energy into mechanical energy. It is the core part that realizes the power output of the motor and is commonly found in various types of motors such as asynchronous motors and permanent magnet motors.

[0003] Currently, to prevent impurities from affecting the operation of the motor, the motor rotor is usually cleaned during motor maintenance. There is now an efficient cleaning solution for motor rotors on the market, which uses a dry ice cleaning machine. Before operation, the rotor usually needs to be supported by a cleaning bracket. However, when using a traditional cleaning bracket, the user needs to manually rotate the motor rotor according to the cleaning progress, change its angle, and keep it stable at that angle so that the dirty side of the rotor faces the user. This operation cannot be completed automatically, and the design is not reasonable.

[0004] Therefore, it is necessary to provide a new cleaning bracket for motor rotors to solve the above-mentioned technical problems. Utility Model Content

[0005] The technical problem solved by this utility model is to provide a cleaning bracket for a motor rotor that can automatically rotate the surface of the motor rotor during the user's cleaning process.

[0006] To solve the above-mentioned technical problems, the present invention provides a cleaning bracket for motor rotor, comprising: a support base, a support structure, and a drive structure. The surface of the support base is provided with a sliding groove. The drive structure includes a fixing frame. Two fixing frames are provided and distributed left and right. Corner pieces are fixedly connected to the left and right side walls of the support base located behind the sliding groove. The two fixing frames are respectively fixedly connected to the top surfaces of the two corner pieces.

[0007] The surface of the fixed frame is slidably connected to a sliding seat, and the top of the sliding seat is fixedly connected to a mounting frame. A movable part is provided on one side of the surface of the mounting frame. Mounting screws are fixedly connected to the side wall surfaces of the two movable parts that are relatively far apart. The mounting screws pass through the interior of the mounting frame. A clamping block is provided on the side of the mounting frame opposite to the movable part. A through hole is opened on the surface of the clamping block. The rod part of the mounting screw passes through the through hole and is fitted with a washer. A mounting nut is threadedly connected to the surface of the mounting screw.

[0008] A cantilever is fixedly connected to the front wall surface of the movable component, and an installation component is rotatably connected between the ends of the two cantilever arms. Several movable sleeves distributed left and right are sleeved on the surface of the installation component. A push wheel is fixedly connected to one end face of the movable sleeve and is sleeved on the installation component. A control motor is fixedly connected to the surface of one side of the cantilever arm, and the output end of the control motor is fixedly connected to one end of the installation component.

[0009] As a further embodiment of this utility model, a limiting groove is formed on the surface of the mounting component, a limiting block is fixedly connected to the inner wall of the movable sleeve, the limiting block and the limiting groove are in sliding fit, and a set screw three is threadedly connected to the outer peripheral surface of the movable sleeve, the pressing end of the set screw three abuts against the outer peripheral surface of the mounting component.

[0010] Through the above technical solution, in this device, the rotor shaft of the motor rotor is supported at both ends on two sets of rotating wheels on the left and right. The drive wheel mainly relies on the kinetic energy provided by the control motor to drive the rotor to rotate. The height and front-to-back position of the drive wheel can be adjusted according to the actual size of the rotor. When the user operates, loosen the two mounting nuts on the left and right, then adjust the height of the drive wheel longitudinally to the appropriate position, and then retighten the mounting nuts. After that, slide the two sliding seats back and forth until the wheel surface of the drive wheel abuts against the outer surface of the rotor. At this time, tighten the first set screw to fix the position of the sliding seat. The wheel surface of the drive wheel and the contact surface between the clamp and the mounting frame can be knurled to improve their friction. According to the above structural design, when the user cleans the rotor surface, the control module can be used to start the control motor, which will drive the mounting parts and several drive wheels fixed on the mounting parts to rotate. The drive wheels will then drive the rotor to rotate slowly. In this way, there is no need to manually adjust the rotor angle, making the operation more time-saving and labor-saving. The design is reasonable.

[0011] As a further embodiment of this utility model, a control module is fixedly connected to the rear wall surface of the mounting bracket on one side via a connecting plate, and the control motor and the control module are electrically connected.

[0012] The above technical solution, through the setting of a control module, allows users to easily control the operation of the motor, and the structural design is reasonable.

[0013] As a further embodiment of this utility model, the support structure includes a support frame. Two support frames are arranged symmetrically on the upper side of the support base. A slider is fixedly connected to the bottom of each of the two support frames. The slider and the slide groove are in sliding fit. A second set screw is threaded to the top of the slider. The pressing end of the second set screw abuts against the bottom inner wall of the slide groove.

[0014] With the above technical solution, the distance between the left and right sets of rotating wheels can be adjusted by the cooperation of the slider and the slide groove. After adjustment, the set screw can be tightened to fix it.

[0015] As a further embodiment of this utility model, a support column is fixedly connected to the surface of the support frame, and a movable arm is slidably connected to the surface of the support column. The surface of the support column is provided with a plurality of positioning holes distributed longitudinally at equal intervals. The surface of the movable arm is provided with an insertion hole, and a locking bolt is inserted into the insertion hole. The rod part of the locking bolt passes through a positioning hole on one side, and a locking nut is threaded to the end of the locking bolt. Rotating wheels are symmetrically connected to the top of the movable arm.

[0016] With the above technical solution, the user can adjust the height of the movable arm according to the size of the rotor. During adjustment, the movable part is slid longitudinally until the insertion hole is aligned with the positioning hole of the appropriate height. At this time, the locking bolt is inserted into the insertion hole. After the other end of the locking bolt passes out from the other side of the insertion hole, it can be tightened and fixed by the locking nut.

[0017] As a further embodiment of this utility model, the bottom surface of the support base located on the front side of the slide groove and the bottom surface of the two corner pieces are all fixedly connected with support feet. The support feet are provided with fixing holes. The left and right side walls of the sliding base are threaded with a set screw, and the pressing end of the set screw abuts against the side wall surface of the fixing frame.

[0018] With the above technical solution, before using the device, the user can open holes corresponding to the fixing holes on the external foundation, and then use expansion bolts and expansion nuts to fix the legs.

[0019] Compared with related technologies, the cleaning bracket for motor rotors provided by this utility model has the following advantages:

[0020] In this device, the rotor shaft of the motor rotor is supported at both ends on two sets of rotating wheels on the left and right. The drive wheels mainly rely on the kinetic energy provided by the control motor to drive the rotor to rotate. The height and front-to-back position of the drive wheels can be adjusted according to the actual size of the rotor. During operation, the user loosens the two mounting nuts on the left and right, then adjusts the height of the drive wheels longitudinally to the appropriate position, and then retightens the mounting nuts. After that, the two sliding seats slide back and forth until the wheel surface of the drive wheel abuts against the outer surface of the rotor. At this time, the first set screw can be tightened to fix the position of the sliding seat. The wheel surface of the drive wheel and the contact surface between the clamp and the mounting frame can be knurled to improve their friction. According to the above structural design, when the user cleans the rotor surface, the control module can be used to start the control motor, which will drive the mounting parts and several drive wheels fixed on the mounting parts to rotate.
