Description

Technical Field

[0001] This utility model relates to the field of motor disassembly technology, and more specifically, to a motor disassembly device. Background Technology

[0002] In the baggage conveyor belt system of an airport, the main power is transmitted by an electric motor. The motor's drive shaft is connected to a speed reducer, which makes the conveyor belt run stably and slowly.

[0003] However, after long-term operation, existing motors may experience abnormal noises, oil leaks, and other malfunctions, requiring the removal of the motor and separation from the reducer. Due to the overly tight connection between the motor's drive shaft and the reducer, coupled with the limited operating space for some motors making it difficult to apply force, as well as the large weight of the motor itself and on-site environmental factors, disassembly is difficult. Utility Model Content

[0004] The purpose of this utility model is to provide a motor disassembly device, which solves the problem that the connection between the motor and the reducer is too tight after the motor is connected, and the motor itself is limited by its size and operating space, making it difficult to disassemble when the motor needs to be repaired.

[0005] This utility model is achieved through the following technical solution: This utility model provides a motor disassembly device, including a connecting disc, a lifting screw connected to the middle of the connecting disc, a pressing head provided at the bottom of the lifting screw, a connecting opening provided at the top of the connecting disc, a limit block connected to the middle of the connecting opening, a connecting bolt connected to the middle of the limit block, a reducer connected to the bottom of the connecting disc, and a drive motor connected to one end of the reducer.

[0006] Preferably, the connecting bolts mate with the bolt holes on the top of the reducer.

[0007] Preferably, the lifting screw passes through the middle of the connecting disc and is connected, and the side wall of the lifting screw is provided with a thread that matches the inner wall of the hole in the middle of the connecting disc.

[0008] Preferably, the extrusion head is a conical protrusion at the bottom of the lifting screw.

[0009] Preferably, the limiting block further includes sliders, which are disposed on both sides of the limiting block.

[0010] Preferably, the connecting opening further includes a slide groove and a displacement screw, with the slide groove disposed on both sides of the middle part of the connecting opening and the displacement screw connected to the middle part of the slide groove.

[0011] Preferably, the slide groove and the slider cooperate, the displacement screw is rotatably connected in the middle of the slide groove, and one end of the displacement screw protrudes from the side wall of the connecting disc.

[0012] Preferably, the displacement screw passes through the slider, and the sidewall of the displacement screw is threaded to match the through hole thread of the slider.

[0013] The technical solution of this utility model has at least the following advantages and beneficial effects: 1. By using a lifting screw connected to the center of the connecting disc on the reducer to lift and lower, the drive shaft of the transmission motor connected inside the reducer is squeezed, causing the drive shaft to shift and thus loosening the tight connection between the transmission motor and the reducer, making disassembly easier.

[0014] 2. The device is also equipped with a connection opening and a limiting block. By sliding the limiting block along the connection opening, the connection position of the connecting bolt can be flexibly adjusted to adapt to the position of different screw holes on the reducer, and at the same time, the fit between the connecting disc and the connecting bolt is more stable.

[0019] The following is combined Figures 1 to 3 This utility model will be described in detail.

[0020] A motor disassembly device includes a connecting disc 1, a lifting screw 2 connected to the middle of the connecting disc 1, a pressing head 201 provided at the bottom of the lifting screw 2, a connecting opening 102 provided at the top of the connecting disc 1, a limiting block 103 connected to the middle of the connecting opening 102, a connecting bolt 101 connected to the middle of the limiting block 103, a reducer 3 connected to the bottom of the connecting disc 1, a drive motor 4 connected to one end of the reducer 3, and the connecting bolt 101 engaging with a bolt hole at the top of the reducer 3.

[0021] First, when it is necessary to separate the drive shaft of the drive motor 4 from the reducer 3, the connecting disc 1 is placed on top of the reducer 3, and then connected to the screw hole on the top of the reducer 3 by the connecting bolt 101, so that the connecting disc 1 can be firmly connected to the reducer 3. Then, the lifting screw 2 is rotated and inserted into the round hole in the middle of the connecting disc 1. Then, by continuous manual control, the lifting screw 2 rotates and descends along the hole of the connecting disc 1, extending into the interior of the reducer 3. The pressing head 201 at the bottom of the lifting screw 2 will abut against one end of the drive shaft of the drive motor 4. Through the inclined surface of the pressing head 201, the drive shaft will be squeezed and displaced as it continues to move downward, thereby separating the drive shaft from the reducer 3, so as to facilitate the disassembly of the drive motor 4.

[0022] Furthermore, the lifting screw 2 passes through the middle of the connecting disc 1 and is connected, and the side wall of the lifting screw 2 is provided with a thread that matches the inner wall of the hole in the middle of the connecting disc 1. The extrusion head 201 is a conical protrusion at the bottom of the lifting screw 2. The limiting block 103 also includes a slider 1031, which is provided on both sides of the limiting block 103. The connecting opening 102 also includes a groove 1021 and a displacement screw 1022. The groove 1021 is provided on both sides of the middle of the connecting opening 102. The displacement screw 1022 is connected to the middle of the groove 1021. The groove 1021 cooperates with the slider 1031. The displacement screw 1022 is rotatably connected to the middle of the groove 1021, and one end of the displacement screw 1022 protrudes from the side wall of the connecting disc 1. The displacement screw 1022 passes through the slider 1031 and is connected, and the side wall of the displacement screw 1022 matches the thread of the through hole of the slider 1031.

[0023] Meanwhile, the connecting bolt 101 passes through the connecting opening 102 and connects to the screw hole on the reducer 3. When the connecting bolt 101 passes through the connecting opening 102, it will pass through the hole in the center of the limiting block 103. The limiting block 103 can be manually controlled to rotate one end of the displacement screw 1022, thereby driving the slider 1031 on one side of the limiting block 103 to move along the slide groove 1021 to adjust the position of the limiting block 103. This allows the limiting block 103 to adapt to different bolt hole positions on the reducer 3. At the same time, the limiting block 103 is connected by the displacement screw 1022 to prevent the limiting block 103 from sliding on its own, making the connection between the connecting disc 1 and the reducer 3 more stable.

[0024] The following is a detailed implementation process of this utility model. First, when it is necessary to separate the drive shaft of the drive motor 4 from the reducer 3, the connecting disc 1 is placed on top of the reducer 3, and then connected to the screw hole on the top of the reducer 3 by the connecting bolt 101, so that the connecting disc 1 can be firmly connected to the reducer 3. Then, the lifting screw 2 is rotated and inserted into the round hole in the middle of the connecting disc 1. Then, by continuous manual control, the lifting screw 2 rotates and descends along the hole of the connecting disc 1, extending into the interior of the reducer 3, so that the pressing head 201 at the bottom of the lifting screw 2 will abut against one end of the drive shaft of the drive motor 4. Through the inclined surface of the pressing head 201, the drive shaft will be squeezed and displaced as it continues to move downward, thereby separating the drive shaft from the reducer 3, so as to facilitate the disassembly of the drive motor 4.

[0025] Meanwhile, the connecting bolt 101 passes through the connecting opening 102 and connects to the screw hole on the reducer 3. When the connecting bolt 101 passes through the connecting opening 102, it will pass through the hole in the center of the limiting block 103. The limiting block 103 can be manually controlled to rotate one end of the displacement screw 1022, thereby driving the slider 1031 on one side of the limiting block 103 to move along the slide groove 1021 to adjust the position of the limiting block 103. This allows the limiting block 103 to adapt to different bolt hole positions on the reducer 3. At the same time, the limiting block 103 is connected by the displacement screw 1022 to prevent the limiting block 103 from sliding on its own, making the connection between the connecting disc 1 and the reducer 3 more stable.
