Description

Technical Field

[0001] The present invention relates to the technical field of motor maintenance, and in particular to a motor maintenance detection system and a detection method. Background Art

[0002] A motor is an electromagnetic device that converts or transmits electrical energy based on the law of electromagnetic induction. In circuits, it's represented by the letter "M" (older standards used "D"). Its primary function is to generate driving torque, serving as a power source for electrical devices and machinery. Motor maintenance is a common problem due to long-term, continuous use and improper operation. Motor maintenance should be performed by qualified personnel to ensure proper operation. Motor maintenance can save costs and improve motor utilization.

[0003] The existing inspection and maintenance methods are mostly to place the motor directly on the ground for inspection and maintenance. However, this method has the defect of being inconvenient for inspection and maintenance, which is easy to cause incomplete inspection accidents and requires re-disassembly and maintenance at a later time, which is more troublesome. At the same time, during maintenance, too much dust adheres to the outside of the motor due to long-term work, and the staff needs to clean it in advance, which increases the workload of the staff and reduces the maintenance efficiency of the motor.

[0011] Preferably, the fourth gear has the same structure as the first gear and is configured as a half gear. When the first gear is engaged with the second gear, the fourth gear is not engaged with the third gear; when the fourth gear is engaged with the third gear, the first gear is not engaged with the second gear.

[0012] Preferably, the dust removal mechanism includes a groove opened on the second support plate, a rack plate is fixedly provided on the inner wall of the groove, a movable gear is meshedly connected to the rack plate, a third rotating rod is provided on the movable gear, and a fan for dust removal is provided on the third rotating rod.

[0013] Preferably, a fixing plate is sleeved on the third rotating rod, an end of the fixing plate away from the third rotating rod is connected to a slider, and a sliding groove cooperating with the slider is formed on the second supporting plate.

[0015] The present invention also discloses a motor maintenance and detection method, which includes a motor maintenance and detection system and the following steps:

[0016] S1: When the device is working, the motor to be tested is placed on a chuck connected to the first rotating rod. By rotating the threaded rod, the threaded rod drives the other chuck closer to the end of the motor to be tested, so that the motor to be tested is clamped between the two chucks. Then, the screw on the chuck is rotated, so that the screw drives the clamping plate to clamp the side wall of the motor to be tested.

[0017] S2: After the motor to be inspected is placed, the drive motor is controlled to operate so that the output end of the drive motor drives the rotating shaft to rotate, so that the first gear and the fourth gear on the rotating shaft are respectively engaged with the second gear and the third gear. When the first gear is engaged with the second gear, the second gear drives the rotating rod and the U-shaped frame connected to the rotating rod to rotate, thereby causing the U-shaped frame to drive the clamped motor to rotate radially;

[0018] S4: When the first gear no longer meshes with the second gear, the fourth gear begins to mesh with the third gear, causing the third gear to drive the worm to rotate. The worm meshes with the worm wheel on the second rotating rod, causing the worm wheel to drive the second rotating rod to rotate. The first rotating rod rotates along with the second rotating rod under the action of the first synchronous wheel and the first belt, thereby causing the first rotating rod to drive the motor to be inspected to rotate through the chuck;

[0019] S4: When the rotating shaft rotates, the fourth rotating rod rotates synchronously with the rotating shaft under the action of the second synchronous wheel and the second belt. The rotation of the fourth rotating rod drives the first connecting plate and the second connecting plate to move, so that the second connecting plate pulls the third rotating rod to move. During the movement of the third rotating rod, the driven gear engages with the rack plate, so that the third rotating rod drives the fan to clean the dust adhered to the motor to be inspected. Then the staff can perform maintenance work on the motor to be inspected.

[0020] Compared with the prior art, the present invention provides a motor maintenance detection system and detection method, which has the following beneficial effects:

[0021] 1. The motor maintenance and inspection system and inspection method can place the motor to be inspected in multiple positions through the driving mechanism to avoid missed inspections and shorten the number of inspections. At the same time, the dust removal mechanism is used to clean the motor to be inspected in multiple positions, thereby speeding up the inspection work efficiency and reducing the labor intensity of the staff.

[0022] 2. The motor maintenance and inspection system and inspection method use the first drive component and the second drive component to alternately flip the motor to be inspected, so that the staff can accurately adjust the area of ​​the motor to be inspected that needs to be inspected and repaired while using one drive motor, and avoid the motor to be inspected from rotating in multiple directions at the same time, which makes the placement of the motor to be inspected difficult to adjust.

[0023] 3. The motor maintenance inspection system and inspection method use two chucks to limit the upper and lower ends of the motor to be inspected, and use the clamping plates in the chucks to limit the side walls of the motor to be inspected, which effectively improves the stability of the motor to be inspected during inspection and prevents the motor to be inspected from slipping during the inspection and flipping process. It can also test motors of different diameters and has strong practicality.

[0024] 4. The motor maintenance and detection system and detection method, through the rotation of the fourth rotating rod, the fourth rotating rod drives the first connecting plate and the second connecting plate to move, so that the second connecting plate pulls the third rotating rod to move back and forth, and the third rotating rod engages the driven gear with the rack plate during the movement, so that the third rotating rod drives the fan to clean the dust adhered to the motor to be inspected. The fan moves left and right during the movement of the third rotating rod, thereby increasing the dust removal range of the fan, thereby ensuring that the fan can effectively remove dust from the motor to be inspected whose position changes when it is flipped.

The rotating shaft 801 is connected to a fourth gear 10 that meshes with the third gear 901, and the connecting plate 902 is also rotatably connected to a second rotating rod 11, and the second rotating rod 11 is fixed with a worm wheel 111 that meshes with the worm 9, and the second rotating rod 11 and the first rotating rod 7 are both connected to a first synchronous wheel 12, and a first belt is arranged between the two first synchronous wheels 12.

[0043] Furthermore, the fourth gear 10 has the same structure as the first gear 8011 and is configured as a half gear. When the first gear 8011 is engaged with the second gear 8021, the fourth gear 10 is not engaged with the third gear 901; when the fourth gear 10 is engaged with the third gear 901, the first gear 8011 is not engaged with the second gear 8021.

[0044] Specifically, by controlling the operation of the driving motor 8, the output end of the driving motor 8 drives the rotating shaft 801 to rotate, so that the first gear 8011 and the fourth gear 10 on the rotating shaft 801 are respectively engaged with the second gear 8021 and the third gear 901.

[0048] Specifically, when the rotating shaft 801 rotates, the fourth rotating rod 161 rotates synchronously with the rotating shaft 801 under the action of the second synchronous wheel 17 and the second belt. The rotation of the fourth rotating rod 161 drives the first connecting plate 1611 and the second connecting plate 1612 to move, so that the second connecting plate 1612 pulls the third rotating rod 141 to move. During the movement, the third rotating rod 141 causes the driven gear 14 to engage with the rack plate 131, and drives the slider 151 to slide in the slide groove 152 through the fixed plate 15, thereby improving the stability of the movement of the third rotating rod 141, so that the third rotating rod 141 drives the fan 142 to clean the dust adhered to the motor 6 to be inspected in the horizontal direction, thereby increasing the dust removal range of the fan 142, and thereby ensuring that the fan 142 can effectively remove dust from the motor 6 to be inspected whose position changes during flipping.

When the first gear 8011 is meshed with the second gear 8021, the second gear 8021 drives the rotating rod 802 and the U-shaped frame 4 connected to the rotating rod 802 to rotate, thereby causing the U-shaped frame 4 to drive the clamped motor 6 to rotate radially.

[0052] S4: When the first gear 8011 is no longer engaged with the second gear 8021, the fourth gear 10 begins to engage with the third gear 901, causing the third gear 901 to drive the worm 9 to rotate. The worm 9 engages with the worm wheel 111 on the second rotating rod 11, causing the worm wheel 111 to drive the second rotating rod 11 to rotate. The first rotating rod 7 rotates along with the second rotating rod 11 under the action of the first synchronous wheel 12 and the first belt, thereby causing the first rotating rod 7 to drive the motor to be inspected 6 to rotate through the chuck 5.

A motor maintenance and detection method, comprising the motor maintenance and detection system according to claim 4, characterized in that: The following steps are also included: S1: When the device is working, the motor to be inspected (6) is placed on the chuck (5) connected to the first rotating rod (7), and the threaded rod (701) is rotated so that the threaded rod (701) drives the other chuck (5) to approach the end of the motor to be inspected (6), so that the motor to be inspected (6) is clamped between the two chucks (5), and then the screw rod (502) on the chuck (5) is rotated so that the screw rod (502) drives the clamping plate (503) to clamp the side wall of the motor to be inspected (6); S2: After the motor (6) to be inspected is placed, the driving motor (8) is controlled to operate, so that the output end of the driving motor (8) drives the rotating shaft (801) to rotate, so that the first gear (8011) and the fourth gear (10) on the rotating shaft (801) are respectively engaged with the second gear (8021) and the third gear (901). When the first gear (8011) is engaged with the second gear (8021), the second gear (8021) drives the rotating rod (802) and the U-shaped frame (4) connected to the rotating rod (802) to rotate, thereby causing the U-shaped frame (4) to drive the clamped motor (6) to rotate radially; S3: When the first gear (8011) is no longer engaged with the second gear (8021), the fourth gear (10) starts to engage with the third gear (901), so that the third gear (901) drives the worm (9) to rotate, and the worm (9) engages with the worm wheel (111) on the second rotating rod (11), so that the worm wheel (111) drives the second rotating rod (11) to rotate, and the first rotating rod (7) rotates with the second rotating rod (11) under the action of the first synchronous wheel (12) and the first belt, thereby causing the first rotating rod (7) to drive the motor (6) to be inspected to rotate through the chuck (5); S4: When the rotating shaft (801) rotates, the fourth rotating rod (161) rotates synchronously with the rotating shaft (801) under the action of the second synchronous wheel (17) and the second belt. The rotation of the fourth rotating rod (161) drives the first connecting plate (1611) and the second connecting plate (1612) to move, so that the second connecting plate (1612) pulls the third rotating rod (141) to move. During the movement, the third rotating rod (141) causes the moving gear (14) to engage with the rack plate (131), so that the third rotating rod (141) drives the fan (142) to clean the dust adhered to the motor (6) to be inspected. Then the staff can perform maintenance work on the motor (6) to be inspected.
