Description

Technical Field

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

[0002] For wheel hub motors, since the motor and wheel hub are often integrated together during manufacturing, when they need to be repaired, the motor is usually disassembled, and then the wheel hub or motor is repaired. When the motor is generally repaired or maintained, the main thing is to check the lubricating oil content inside the motor, remove the dust inside the motor, and whether the motor torque is reduced. However, when the wheel hub is repaired or maintained, there are often the following inconveniences:

[0003] 1. At present, during the long-term use of the hub motor, the hub, as the main load-bearing component, is prone to deformation under the long-term pressure of gravity. When correcting the hub, it is often affected by the motor, making it inconvenient to correct.

[0039] The embodiments of the present invention are described below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0040] In the description of the embodiments of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms, "connection" and "installation" should be understood in a broad sense. For example, "connection" can be a detachable connection or a non-detachable connection; it can be a direct connection or an indirect connection through an intermediate medium.

The directional terms mentioned in the embodiments of the present invention, such as "inside", "outside", "top", "bottom", etc., are only reference to the directions of the accompanying drawings. Therefore, the directional terms used are for better and clearer explanation and understanding of the embodiments of the present invention, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the embodiments of the present invention.

[0041] Example 1

[0042] Reference Figure 1-Figure 10 In the present embodiment, a maintenance device is first constructed by constructing a bottom box 1 as a supporting base of the entire maintenance device, and a table 2 is fixedly installed on the top of the bottom box 1. An L-shaped frame 3 is firmly installed on one side of the top of the table 2, and two support columns 4 are symmetrically fixedly installed on the top inner wall of the L-shaped frame 3. The bottom ends of the two support columns 4 are connected to the top of the table 2 to form a stable support structure.

[0043] Next, a bracket 13 is installed on one side of the top of the L-shaped frame 3 by a rotational connection, and a control display 131 is installed on the bracket 13 to display and maintain various parameters and instructions during the process. For the construction of the drive mechanism, first, a rotationally connected bearing ring 91 is installed on the top of the table 2 to place the hub motor 24 to be tested. On the top of the L-shaped frame 3, a support ring 5 is installed by a rotational connection, and a sliding connection shaft 6 is passed through the support ring 5. The bottom end of the shaft 6 extends into the L-shaped frame 3 and is connected to a pressing assembly. The pressing assembly specifically includes a connecting cover 7 fixedly installed at the bottom end of the shaft 6, a connecting ring 8 is fixedly sleeved on the connecting cover 7, and the bottom of the connecting ring 8 is slidably connected to the same support ring 10 through multiple connecting rods 11. A pressing tube 9 is fixedly installed through the support ring 10, and the pressing tube 9 is used to press the hub motor 24. A first tension spring 12 is sleeved on the connecting rod 11 to provide elastic support for the pressing tube 9 to ensure buffer protection during the pressing process.

[0044] A limit assembly is provided at the top of the support ring 5, which is used to brake and limit the rotating shaft 6. The limit assembly includes a limit frame 17 fixed on the top of the support ring 5, and two limit plates 18 are symmetrically slidably connected in the limit frame 17. A connecting plate 19 is slidably connected between the two limit plates 18, and the bottom of the connecting plate 19 is fixedly connected to the top of the rotating shaft 6. A movable frame 20 is fixedly installed on the limiting plate 18, and the movable frame 20 is slidably sleeved on the limit frame 17, and a fixed plate 21 is fixedly installed on one side of the bottom. A sliding connecting rod 22 passes through the fixed plate 21, and one end of the rod 22 can be inserted into the slots on both sides of the limit frame 17 to achieve limiting. A second tension spring 23 is sleeved on the rod 22 to provide a reset force.

[0045] In addition, a driving motor 14 is fixedly installed on one side of the top of the L-shaped frame 3. The driving motor 14 is electrically connected to the control display 131. The driving bevel gear 15 is fixedly installed on the output shaft thereof, and meshes with the driven bevel gear 16 fixedly sleeved on the support ring 5. When the driving motor 14 is started, it can drive the support ring 5 and the rotating shaft 6 to rotate, and then drive the hub motor 24 to rotate, so as to facilitate comprehensive detection of the hub 241.

[0046] The detection mechanism is connected to the top of the table 2 and the L-shaped frame 3 respectively, and is used to detect and mark the deformation of the hub 241. The correction mechanism is installed on one side of the two support columns 4, and the bottom extends into the bottom box 1 and is connected to the inner wall of the bottom box 1.

[0047] When the detection mechanism finds that the wheel hub 241 is deformed, the correction mechanism can press and correct the deformed part. In specific implementation, first place the wheel hub motor 24 on the load-bearing ring 91, push the rotating shaft 6 downward, so that the pressing tube 9 presses the wheel hub motor 24, and locks the rotating shaft 6 through the limit assembly. Start the drive motor 14 to drive the wheel hub motor 24 to rotate, and at the same time the detection mechanism detects the wheel hub 241. If deformation is found, the correction mechanism is started to press and correct it. During the whole process, the control display 131 can display the operation status and detection results in real time to ensure the efficiency and accuracy of the maintenance process.

[0048] The core component of the detection mechanism includes a third slide rail 45 fixedly mounted on one side of the L-shaped frame 3. A baffle 46 is fixed on the top of the third slide rail 45 to limit the sliding range of the limit slide 48. On the third slide rail 45, we slide the limit slide 48, which can move freely along the slide rail.

[0049] A mounting plate 50 is fixedly mounted on one side of the limiting slide plate 48, and the mounting plate 50 carries an arc-shaped detection strip 52. The arc-shaped detection strip 52 is designed to match the shape of the inner wall of the wheel hub 241 so that it can fit closely to the inner wall of the wheel hub during detection. During installation, the arc-shaped detection strip 52 is inserted into the wheel hub 241 to ensure that it is in full contact with the inner wall of the wheel hub.

[0050] In order to limit the longitudinal movement range of the mounting plate 50, a limiting rod 51 is slidably connected to the mounting plate 50. The top and bottom ends of the limiting rod 51 are fixedly connected to the top inner wall of the L-shaped frame 3 and the top of the table 2 respectively, so that the mounting plate 50 can move longitudinally stably under the guidance of the limiting rod.

[0051] When the wheel hub motor 24 is placed on the carrying ring 91 and started, the wheel hub 241 will rotate accordingly. At this time, the contact between the arc detection strip 52 and the inner wall of the wheel hub 241 will achieve comprehensive detection. If the wheel hub 241 is deformed, this deformation will be transmitted to the mounting plate 50 through the arc detection strip 52, thereby driving the mounting plate 50 and the limiting slide plate 48 to move longitudinally on the third slide rail 45.

[0052] In order to accurately measure the deformation of the wheel hub 241, we fixedly installed a receiving end 47 at the bottom of the baffle 46, and fixedly installed a distance sensor 49 at the top of the limit slide 48. The distance sensor 49 cooperates with the receiving end 47 to measure the distance change between the two in real time. It is important that the receiving end 47 and the distance sensor 49 are both electrically connected to the control display 131, so the deformation data will be displayed on the control display 131 in real time for the operator to refer to.

[0053] In addition, in order to mark the deformed area of ​​the wheel hub 241, we fixedly installed an L-shaped plate 53 on one side of the top of the mounting plate 50, and fixed a second electric push rod 54 on the top of the L-shaped plate 53. The output shaft of the second electric push rod 54 extends into the L-shaped plate 53, and a marking pen 55 is fixedly installed. The second electric push rod 54 is also electrically connected to the control display 131, so when the wheel hub 241 is deformed and detected, the operator can start the second electric push rod 54 to drive the marking pen 55 to move downward to mark the deformed area of ​​the wheel hub 241. In this way, in the subsequent correction process, the operator can accurately locate the deformed area and perform targeted repair work.

[0054] The present application can be used in the field of motor maintenance technology, and can also be used in other fields applicable to the present application.

[0055] Example 2

[0056] refer to Figure 3 , Figure 7 and Figure 8, improved on the basis of the first embodiment: a motor maintenance device, which is applied to the field of motor maintenance technology, the core component of the correction mechanism includes a mounting rod 25, which is firmly fixed on one side of the two support columns 4. On the mounting rod 25, we symmetrically rotate and connect two rotating rods 26, and the two rotating rods 26 are jointly fixed with a pressure rod 27. The pressure rod 27 is designed to be able to be placed on the wheel hub 241 so as to apply pressure to the wheel hub when needed.

[0057] In order to drive the pressure rod 27 to move up and down, we symmetrically rotate and sleeve two pull rods 28 on the pressure rod 27. At the same time, we fixedly install a first electric push rod 42 on the inner wall of the bottom of one side of the bottom box 1. The output shaft of the first electric push rod 42 is connected to a set of complex transmission components, which can cross the boundary of the bottom box 1 and are connected to the two pull rods 28 respectively.

[0058] When the wheel hub 241 needs to be corrected, the first electric push rod 42 is first started. As the first electric push rod 42 extends, it starts to drive the transmission assembly to move. The detailed structure of the transmission assembly includes a second slide rail 41 on the bottom inner wall of the bottom box 1 and a transmission slide plate 40 slidably connected thereto. The output shaft of the first electric push rod 42 is directly fixedly connected to one side of the transmission slide plate 40, so that the transmission slide plate 40 can be pushed to slide on the second slide rail 41.

[0059] Two limit rings 38 are fixedly installed on the top of the transmission slide 40, and the two limit rings 38 are slidably connected to a connecting seat 39. The bottom end of the L-shaped rod 37 is rotatably connected to the top of the connecting seat 39, so that when the transmission slide 40 moves, it can push the L-shaped rod 37 to rotate through the limit rings 38 and the connecting seat 39.

[0060] The top end of the L-shaped rod 37 is rotatably connected to a collar 34, and a slide bar 33 is slidably connected through the collar 34. One end of the slide bar 33 is fixedly connected to a moving plate 30 in the bottom box 1, and the other end is fixedly installed with a connecting slide plate 44. The connecting slide plate 44 slides on the first slide rail 35, and the first slide rail 35 is fixedly installed on one inner wall of the bottom box 1.

[0061] When the L-shaped rod 37 rotates, it drives the collar 34 to perform an arc motion, and this arc motion is transmitted to the movable plate 30 through the slide rod 33, so that the movable plate 30 can move downward along the limit rod 29. A transmission tube 31 is fixedly installed on both sides of the movable plate 30, and a transmission rod 32 is slidably connected in the transmission tube 31. The other end of the transmission rod 32 extends to the outside of the bottom box 1 and is fixedly connected to the bottom of one side of the corresponding pull rod 28.

[0062] Therefore, when the moving plate 30 moves downward, it drives the two pull rods 28 to move downward through the two transmission tubes 31 and the corresponding transmission rods 32. Since the pull rods 28 are rotatably connected to the pressure rods 27, the downward movement of the pull rods 28 drives the pressure rods 27 to move downward, thereby applying downward pressure to the wheel hub 241 mounted thereon, thereby correcting the deformation area of ​​the wheel hub 241.

[0063] In addition, in order to provide stable pressure and ensure the reset capability of the structure, a compression spring 43 is installed at the bottom of the connecting seat 39. The bottom end of the compression spring 43 is fixedly connected to the top of the transmission slide 40. When the L-shaped rod 37 rotates and pushes the connecting seat 39 to move downward, the compression spring 43 will be compressed. When the first electric push rod 42 moves in the opposite direction and the transmission slide 40 and the L-shaped rod 37 return to the initial position, the compression spring 43 in the compressed state will assist in pushing the connecting seat 39 to reset upward, ensuring that the entire transmission assembly can work smoothly.

[0064] Steps:

[0065] S1, first place the hub motor 24 on the carrying ring 91, and insert the arc detection strip 52 into the hub 241;

[0066] S2, push the rotating shaft 6 downward, the connecting cover 7 moves downward with the rotating shaft 6, and at this time, it can drive the pressing tube 9 to move downward, and use the pressing tube 9 to press the hub motor 24, and in the process of the connecting cover 7 moving downward, a plurality of first tension springs 12 will be used to provide corresponding elastic support, so that when the hub motor 24 is pressed and limited by the pressing tube 9, the hub motor 24 can be provided with corresponding buffer protection, and when the connecting plate 19 moves downward with the rotating shaft 6, under the sliding limit action of the two limiting plates 18, the rotating shaft 6 can be longitudinally slidably limited, and after the hub motor 24 is pressed and limited by the pressing tube 9, the two insertion rods 22 can be released at this time, and the second tension spring 23 in a stressed state can drive the insertion rod 22 to move, so that the insertion rod 22 is inserted into the corresponding slot, so that the connecting plate 19 can be limited, so that the rotating shaft 6 can be longitudinally limited, and the hub motor 24 can be stably clamped by the pressing tube 9;

[0067] S3. When the driving motor 14 is started by operating the control display 131 to drive the active bevel gear 15 to rotate, the supporting ring 5 can be driven to rotate under the meshing transmission action with the driven bevel gear 16, and the rotating shaft 6 can be driven to rotate at this time, and the transmission of the rotating shaft 6, the connecting cover 7 and the pressure pipe 9 can drive the hub motor 24 to rotate, so that when the wheel hub 241 rotates, the wheel hub 241 can be fully detected by the detection mechanism, so as to accurately locate the part that needs to be repaired;

[0068] S4. When the wheel hub motor 24 rotates to drive the wheel hub 241 to rotate, the arc-shaped detection strip 52 can fully contact the wheel hub 241, and when the wheel hub 241 is deformed, the arc-shaped detection strip 52 can drive the mounting plate 50 to move longitudinally, that is, drive the limit slide plate 48 to move longitudinally, so as to drive the distance measuring sensor 49 to move longitudinally. At this time, when the distance measuring sensor 49 moves longitudinally, the deformation of the wheel hub 241 can be measured;

[0069] S5. After the wheel hub 241 is deformed, the second electric push rod 54 can be started by operating the control display 131 to drive the marking pen 55 to move downward, and the deformed area of ​​the wheel hub 241 can be marked with the marking pen 55, so that the wheel hub 241 can be accurately positioned when being corrected later;

[0070] S6. After the marked part is rotated to the bottom of the pressure rod 27, the first electric push rod 42 can be started by operating the control display 131 to drive the transmission slide plate 40 to move horizontally, and the two limit rings 38 can be used to drive the connecting seat 39 to move. At this time, a thrust can be applied to the L-shaped rod 37, so that the L-shaped rod 37 rotates, which can drive the collar 34 to move downward in an arc shape, and can drive the slide rod 33 to move downward, so that stable pressure can be provided when pressing the wheel hub 241, and when the L-shaped rod 37 rotates, it can push the connecting seat 39 to move downward, and the compression spring 43 is compressed. The compression is performed so that when the transmission slide plate 40 moves in the reverse direction, the compression spring 43 in the stressed state can assist in pushing the connecting seat 39 to reset upward, and when the slide bar 33 moves downward, it can drive the movable plate 30 to move downward. When the movable plate 30 moves downward, the two pull rods 28 can be driven downward by the two transmission tubes 31 and the corresponding transmission rods 32, so that the pressure rod 27 can move downward, and under the rotation support of the two rotating rods 26, the pressure rod 27 can move downward in an arc shape, so as to apply pressure to the wheel hub 241 and correct the deformed area of ​​the wheel hub 241.
