Description

Technical Field

[0001] This invention relates to the field of motor manufacturing technology, and in particular to a motor disassembly device. Background Technology

[0002] like Figure 1 The image shows a common type of motor, which can be simply disassembled into a rear cover and a front cover. The stator and rotor are installed inside the rear cover, and a metal cylinder is also provided on the rear cover corresponding to the power lines. This cylinder can be connected to a nut for fixing. The blades are located on the front cover. During maintenance or quality inspection, it is usually necessary to separate the front cover and the rear cover. However, disassembling the motor after installation requires overcoming a large force, so disassembling the motor is actually quite difficult and is usually not performed.

[0003] Current technology typically involves knocking the front and rear covers of a motor apart. While this method effectively separates the motor, knocking can damage the motor's casing, potentially causing injury or loss. Summary of the Invention

[0004] To address the problem that existing motor disassembly methods easily lead to motor damage, this application provides a motor disassembly device, the specific solution of which is as follows.

[0005] A motor disassembly device includes a disassembly base, on which a clamping assembly is provided for clamping the front cover of the motor. A separation assembly is provided on the upper side of the disassembly base for clamping the rear end of the motor. The separation assembly can drive the rear end of the motor to move in a vertical direction. The separation assembly includes a separation frame, on which a separation cylinder and separation grippers are provided. The separation grippers are fixedly mounted on the piston rod of the separation cylinder. The separation cylinder can drive the separation grippers to move in a vertical direction. The shape of the separation grippers corresponds to that of the nut at the rear end of the motor.

[0006] By adopting the above technical solution, the clamping component can clamp and fix the front cover of the motor, and the separation component can clamp the rear end of the motor and drive the separation claw to move in the vertical direction through the separation cylinder. Since the shape of the separation claw corresponds to the nut at the rear end of the motor, it is convenient to cooperate with the nut, thereby driving the rear end of the motor to move in the vertical direction, realizing the separation and disassembly of the front and rear ends of the motor. The front cover and rear cover of the motor can be separated without hitting the motor, which can reduce the damage during motor disassembly.

[0007] Optionally, the separation frame is further provided with guide posts, which are set perpendicular to the ground. The guide posts are provided with guide plates on the separation claws corresponding to the guide posts, and the guide posts pass through the guide plates. The guide plates can slide along the guide posts.

[0008] By adopting the above technical solution, the guide column and guide plate work together to make the separation gripper slide along the guide column, ensuring the stability and accuracy of the separation gripper during vertical movement, thereby improving the efficiency and quality of motor disassembly.

[0009] Optionally, a plurality of support columns are provided between the separation frame and the disassembly base. One end of the support column is fixedly connected to the disassembly base, and the other end of the support column is fixedly connected to the separation frame. The support columns are arranged parallel to the guide columns.

[0010] By adopting the above technical solutions, the support column can stably lift the separation frame, provide support for the separation frame, and improve the stability of the separation gripper.

[0011] Optionally, the separating gripper is provided with a clearance groove and a limiting groove, the clearance groove and the limiting groove are connected, the clearance groove is inserted into the rear end of the motor, and the limiting groove is used to embed the nut of the motor.

[0012] By adopting the above technical solution, the rear end of the motor can extend into the clearance groove and connect with the nut in the limiting groove. The nut can be fixed by the limiting groove. At this time, the motor can be driven by the separation claw, which can effectively realize the separation of the front cover and the rear cover of the motor.

[0013] Optionally, the clamping assembly includes a movable base and a fixed base. The fixed base is fixedly connected to the plug-in base, and the movable base is slidably connected to the disassembly base. The fixed base and the movable base are provided with corresponding clamping grooves, and the clamping grooves are all set to correspond to the shape of the motor front cover.

[0014] By adopting the above technical solution, the clamping grooves on the movable seat and the fixed seat that correspond to the shape of the motor front cover can be used to achieve stable clamping of the motor front cover, which facilitates the subsequent disassembly of the motor.

[0015] Optionally, a pull screw is provided between the movable seat and the fixed seat. One end of the pull screw is rotatably connected to the movable seat, and the other end of the pull screw is threadedly connected to the fixed seat. When the pull screw rotates, it can drive the movable seat to move toward or away from the fixed seat.

[0016] By adopting the above technical solution and setting a pull screw to control the moving seat, the movement of the moving seat can be adjusted simply by adjusting the pull screw, so that the moving seat can clamp the motor and improve the convenience of adjustment.

[0017] Optionally, the pull screws are respectively disposed at both ends of the moving seat along its length.

[0018] By adopting the above technical solution, the pull screw is set at both ends of the moving seat along the length direction, which can make the moving seat move stably toward or away from the fixed seat when rotating. When adjusting the moving seat, it can be adjusted from both sides, so that the motor can be clamped more stably.

[0019] Optionally, a tension spring is also provided between the movable seat and the fixed seat, and one end of the tension spring has a tendency to pull the movable seat toward the fixed seat.

[0020] By adopting the above technical solution, the tension spring is set between the moving seat and the fixed seat and has the tendency to pull the moving seat toward the fixed seat. This allows the moving seat to move toward the fixed seat more stably, which can assist in the adjustment of the moving seat and enhance the clamping effect on the motor front cover. This prevents the motor front cover from loosening during disassembly and ensures that the disassembly work is carried out smoothly.

[0021] Optionally, the tension spring is sleeved on the tension screw.

[0022] By adopting the above technical solution, the tension spring is sleeved on the tension screw, which can prevent the tension spring from shifting or shaking during operation, ensuring that it stably pulls the moving seat, and further improving the clamping stability of the clamping assembly on the motor front cover.

[0023] A method for disassembling an electric motor, comprising the electric motor disassembly device according to any one of claims 1-9, comprising the following method: A. After removing the screws from the motor, place it into the disassembly housing; B. Adjust the moving seat clamping motor; C. Move the separation gripper so that it faces the rear end of the motor; D. Screw the nut connected to the rear end of the motor into the limiting groove so that the nut abuts against the separation jaws; E. Driving the separation gripper upwards will move the motor's rear cover away from the rear cover.

[0024] By adopting the above technical solution, the front cover of the motor is clamped by the clamping component on the disassembly base, the rear end of the motor is clamped by the separation component and driven to move vertically, and the motor screws are removed and placed into the disassembly base, the moving base is adjusted to clamp the motor, the moving separation claw is aligned with the rear end of the motor, the nut is screwed into the limit groove to abut against the separation claw, and the separation claw is driven upward, thus achieving effective separation of the front and rear covers of the motor and disassembling the motor.

[0025] In summary, this application has at least the following beneficial effects: This application solves the problem that the existing motor disassembly methods are prone to damage to the motor. This application sets up a disassembly base and a device that can clamp the motor. After clamping the front cover of the motor, the rear cover of the motor can be pulled upward to complete the disassembly of the motor. The front cover and the rear cover can be separated without knocking the motor, which can reduce the damage to the motor during disassembly and improve the convenience of motor disassembly.

[0032] The present application will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0033] Example 1 An electric motor disassembly device, such as Figure 2 and Figure 3 As shown, the device includes a disassembly base 1, on which a clamping assembly 2 is mounted. The clamping assembly 2 is used to clamp the front cover of the motor. A separation assembly 3 is mounted on the upper side of the disassembly base 1. The separation assembly 3 is used to clamp the rear end of the motor and can drive the rear end of the motor to move vertically. In specific implementation, the clamping assembly 2 clamps... Figure 1 The front cover of the motor and the separation component 3 can clamp the rod-shaped part at the rear end of the motor. Then, by pulling the rear end of the motor upward, the front cover and the rear cover of the motor can be separated.

[0034] like Figure 2 and Figure 3As shown, the separation assembly 3 includes a separation frame 31, on which a separation cylinder 32 and a separation gripper 33 are mounted. The gripper of the separation frame 31 is fixedly mounted on the piston rod of the separation cylinder 32. The separation cylinder 32 can drive the separation gripper 33 to move vertically. The shape of the separation gripper 33 corresponds to the nut at the rear end of the motor. In specific implementation, the gripping of the separation gripper 33 depends on the cooperation between the nut and the rear end of the motor. Subsequently, the upward movement of the separation gripper 33 can drive the entire rear cover of the motor to move upward.

[0035] like Figure 2 and Figure 3 As shown, the separation frame 31 is also equipped with a guide post 311, which is perpendicular to the ground. A guide plate 331 is provided on the separation gripper 33 corresponding to the guide post 311, with the guide post 311 penetrating through the guide plate 331. The guide plate 331 can slide along the guide post 311. In practical implementation, the guide post 311 provides guidance for the movement of the separation gripper 33, enabling more stable separation of the front and rear covers and further improving stability.

[0036] like Figure 2 and Figure 3 As shown, multiple support columns 11 are provided between the separation frame 31 and the disassembly base 1. One end of the support column 11 is fixedly connected to the disassembly base 1, and the other end of the support column 11 is fixedly connected to the separation frame 31. The support column 11 is arranged parallel to the guide column 311. In specific implementation, the support column 11 can provide a support position for the separation frame 31, so that the separation claws 33 on the separation frame 31 can stably perform disassembly.

[0037] like Figure 2 and Figure 3 As shown, the separating gripper 33 is provided with a clearance groove 332 and a limiting groove 333. The clearance groove 332 and the limiting groove 333 are connected. The clearance groove 332 is for the rear end of the motor to extend into, and the limiting groove 333 is used to embed the nut of the motor. In specific implementation, when clamping, the rear end of the motor needs to be extended into the clearance groove 332 and then into the limiting groove 333. Then, the nut is tightened on the rear end of the motor. The nut will then interfere with the separating gripper 33. Subsequently, the separating gripper 33 moves upward to clamp the motor.

[0038] like Figure 2 and Figure 3 As shown, the clamping assembly 2 includes a movable base 21 and a fixed base 22. The fixed base 22 is fixedly connected to the plug-in base, while the movable base 21 is slidably connected to the disassembly base 1. The fixed base 22 and the movable base 21 are provided with corresponding clamping grooves 23, and the clamping grooves 23 are all set to correspond to the shape of the motor front cover.

[0039] like Figure 2 and Figure 3As shown, a pull screw 24 is provided between the movable seat 21 and the fixed seat 22. One end of the pull screw 24 is rotatably connected to the movable seat 21, and the other end is threadedly connected to the fixed seat 22. When the pull screw 24 rotates, it can drive the movable seat 21 to move toward or away from the fixed seat 22. The pull screw 24 is respectively provided at both ends of the movable seat 21 along its length.

[0040] like Figure 2 and Figure 3 As shown, a tension spring 25 is also provided between the movable seat 21 and the fixed seat 22. One end of the tension spring 25 has a tendency to pull the movable seat 21 toward the fixed seat 22. The tension spring 25 is sleeved on the tension screw 24.

[0041] A method for disassembling an electric motor, comprising the electric motor disassembly device described above, employing the following method: A. After removing the screws from the motor, place them into the disassembly base 1. These screws refer to the screws between the front cover and the rear cover of the motor. B. Adjust the moving seat 21 to clamp the motor; C. Move the separation gripper 33 so that the separation gripper 33 is aligned with the rear end of the motor; D. Screw the nut connected to the rear end of the motor into the limiting groove 333 so that the nut abuts against the separation claw 33; E. Driving the separation gripper 33 upwards will move the motor's rear cover away from the rear cover, completing the disassembly.

[0042] Working principle: There is no need to hit the motor. Simply clamp the motor and pull the rear end of the motor upward to disassemble it, reducing the risk of motor damage during disassembly.

[0043] Example 2 like Figure 5As shown, the main difference between Embodiment 2 and Embodiment 1 is that Embodiment 2 has a nut holder 334 at the separation gripper 33. The nut holder 334 is located at the limiting groove 333. The nut holder 334 is arranged around the nut holder 334 and is used to abut against the nut. A rotating motor 34 is fixedly arranged above the nut holder 334 at the separation gripper 33. A mating key 341 is arranged on the rotating shaft of the rotating motor 34. The mating key 341 is arranged to correspond to the shape of the nut and can drive the nut to rotate. In practice, the nut is placed in the nut holder 334 beforehand. When the separation claw 33 moves toward the motor, the rear end of the motor can push the nut upward along the nut holder 334. When the nut is separated from the nut holder 334, it can be pushed into the mating key 341. At this time, the rotating motor 34 drives the mating key 341 to move. The rotating motor 34 can drive the nut to connect to the rear end of the motor. At this time, the separation claw 33 moves upward to remove the back cover. To remove the back cover from the separation claw 33, the rear end needs to be moved upward from the nut holder 334 to detach. The nut holder 334 serves to restrict the nut and prevent it from falling out of the separation claw 33.

[0044] like Figure 5 As shown, the movable base 21 is also equipped with an elastic plate 26 and a pressure sensor 261. The elastic plate 26 tends to move towards the clamping groove 23, and the pressure sensor 261 can detect the force on the elastic plate 26. In specific implementations, the pressure sensor 261 can be displayed in various ways, such as an electronic digital display screen or a computer. The elastic plate 26 can directly contact the motor, thereby determining the clamping status through the reaction force of the motor. The elastic plate 26 is supported by a spring, thus possessing elasticity. The elastic reaction acts on the pressure sensor 261, which can then detect the pressure on the motor, thereby determining whether the motor is in a clamped state and whether it can be disassembled. This reduces the possibility of wear caused by friction between the motor and the clamping assembly 2 due to the motor not being clamped.

[0045] Working principle: The basic working principle is the same as that of Embodiment 1, but an additional component that can automatically tighten the nut is added, and the clamping status of the motor is observed by the pressure sensor 261, thereby further improving the convenience of disassembly and further reducing the possibility of motor damage.

[0046] The above are preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made to the structure, shape and principle of this application should be covered within the scope of protection of this application.
