Description

Technical Field

[0001] This utility model relates to the field of plastic-encapsulated motor disassembly technology, and in particular to a plastic-encapsulated motor separation device. Background Technology

[0002] Plastic-encapsulated motors are motors that use plastic encapsulation technology to encapsulate the stator core and coils of the motor as a whole using engineering plastics. Currently, plastic-encapsulated motors are usually integrally injection molded, with fewer parts in the assembly process, basically forming a component structure. Although assembly is simple and efficient, existing plastic-encapsulated motors are basically fixed by a tight fit between the injection-molded stator and the end cover, which makes disassembly and separation difficult and the disassembly and separation efficiency at the production end is extremely low.

[0003] Currently, disassembly and separation can only be achieved using tools such as flathead screwdrivers. However, the disassembly and separation process is difficult to control due to torque, resulting in uneven stress on motor components and a high rate of damage and scrapping of some parts. Furthermore, the process is cumbersome for employees, involves high equipment costs, poses safety hazards, and has limited practical applicability. Therefore, further improvements to the existing technology are necessary. Utility Model Content

[0004] The technical problem to be solved by this utility model is to provide a plastic-encapsulated motor separation device that reduces the difficulty of operation and the scrap rate, in light of the above-mentioned prior art.

[0005] The technical solution adopted by this utility model to solve the above-mentioned technical problems is as follows: a plastic-encapsulated motor separation device, wherein the plastic-encapsulated motor includes a stator assembly, a rotor assembly and an end cover, the rotor assembly is disposed inside the stator assembly, the end cover is connected to the stator assembly, the rotor assembly includes a rotating shaft passing through and connected to the end cover, the rotating shaft being at least partially exposed outside the end cover, characterized in that: the plastic-encapsulated motor separation device includes a movable rod detachably connected to the rotating shaft, the movable rod being arranged in a manner that allows it to move along the extension direction of the rotating shaft, the rotating shaft being able to move with the movable rod, thereby causing both the end cover and the rotor assembly to separate from the stator assembly.

[0006] To facilitate the assembly between the moving rod and the rotating shaft, preferably, the moving rod is arranged along the extension direction of the rotating shaft, and the moving rod has a shaft hole in its axial direction for the rotating shaft to pass through.

[0007] For easy disassembly, the movable rod is provided with a first hand lever for gripping and controlling the movement of the movable rod along the extension direction of the pivot.

[0008] To make operation easier for users, preferably, the moving rod and the first hand rod together form a lever structure, with the connection point of the moving rod and the first hand rod serving as the fulcrum.

[0009] To achieve a detachable connection between the moving rod and the rotating shaft, preferably, a shaft pin is provided on the outer wall of the portion of the rotating shaft exposed outside the end cover, and a slot is provided on the moving rod for the shaft pin to be engaged.

[0010] To facilitate the assembly of the pin, the slot is provided near the first end of the moving rod. The moving rod has a pin groove, the starting end of which is located on the first end of the moving rod, and the end of which is connected to the slot.

[0011] In order to apply axial force to the shaft pin and ensure that the shaft pin is subjected to uniform force and other components are not subjected to force, the slot is provided along the circumferential direction of the rotating shaft.

[0012] Preferably, there are two pins, which are disposed opposite to each other on the outer wall of the rotating shaft. Correspondingly, there are two slots, and each slot corresponds to one of the pins.

[0013] Preferably, the outer peripheral wall of the moving rod is provided with an external thread, and the plastic-sealed motor separation device further includes a separation component facing the end cover opening. The top of the separation component is provided with a through hole for the moving rod to pass through, and the wall of the through hole is provided with an internal thread that can be threadedly connected with the external thread.

[0014] To assist in the movement of the moving rod and thus separate the rotating shaft from the end cover, the plastic-sealed motor separation device also includes a second lever, and the separation component has mounting holes for installing the second lever.

[0015] Compared with existing technologies, the advantages of this invention are as follows: by detachably connecting the movable rod to the rotating shaft, and utilizing the movable rod to move along the extension direction of the rotating shaft, the rotating shaft can move with the movable rod, thereby separating the end cover and rotor assembly from the stator assembly. Therefore, this separation device can quickly and reliably separate the encapsulated motor without damaging the rotating shaft and end cover, meeting the requirements of high operability and practicality in production, greatly reducing costs and improving efficiency, lowering operational difficulty, and reducing safety hazards during operation.

[0022] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments.

[0023] The encapsulated motor in this embodiment includes a stator assembly a, a rotor assembly b, and an end cover 10. The rotor assembly b is disposed within the stator assembly a, and the end cover 10 is connected to the stator assembly a. The rotor assembly b includes a rotating shaft 20 that passes through and is connected to the end cover 10, with at least a portion of the rotating shaft 20 exposed outside the end cover 10. The encapsulated motor in this embodiment is prior art, and its details can be found in Chinese invention patent application number CN 202111018363.4 (publication number CN113765272A), entitled "An Encapsulated Motor," which will not be elaborated upon here.

[0024] like Figures 1-6 As shown, the encapsulated motor separation device in this embodiment includes a movable rod 1 that is detachably connected to the rotating shaft 20. The movable rod 1 is arranged in such a way that it can move along the extension direction of the rotating shaft 20. The rotating shaft 20 can move with the movable rod 1, thereby separating the end cover 10 and the rotor assembly b from the stator assembly a.

[0025] like Figure 2 As shown, in this embodiment, the moving rod 1 is arranged along the extension direction of the rotating shaft 20, and the moving rod 1 is provided with a shaft hole 11 for the rotating shaft 20 to pass through in its axial direction.

[0026] Additionally, a pivot pin 3 is provided on the outer wall of the portion of the rotating shaft 20 exposed outside the end cover 10. A slot 12 is provided on the moving rod 1 for the pivot pin 3 to be engaged. The slot 12 is located adjacent to the first end of the moving rod 1. A pivot pin groove 13 is provided on the moving rod 1, with the starting end of the groove 13 located on the first end of the moving rod 1, and the end of the groove 13 communicating with the slot 12. Figure 3 As shown, in this embodiment, the slot 12 is arranged along the circumferential direction of the rotating shaft 20, and the pin groove 13 is arranged along the axial direction of the rotating shaft 20. This allows the pin 3 to be guided by the pin groove 13, and then the pin 3 slides into the slot 12 for positioning. The slot 12 then applies axial force to the pin 3, and the rotation of the moving rod 1 also applies axial force to the pin 3, ensuring that the pin 3 is subjected to uniform force while other components are not stressed. This allows for efficient and rapid disassembly and separation of the encapsulated motor.

[0027] like Figure 4As shown, in this embodiment, there are two shaft pins 3, which are arranged opposite to each other on the outer wall of the rotating shaft 20. Correspondingly, there are two slots 12, which correspond one-to-one with the shaft pins 3.

[0028] The movable lever 1 is equipped with a first hand lever 2 for gripping and controlling its movement along the extension direction of the rotating shaft 20. The movable lever 1 and the first hand lever 2 together form a lever structure, with the connection point between the movable lever 1 and the first hand lever 2 serving as the fulcrum. Figure 1 As shown, in this embodiment, the first lever 2 is set perpendicular to the moving lever 1.

[0029] The moving rod 1 is a screw, and its outer peripheral wall is provided with an external thread 14. The encapsulated motor separation device also includes a separation component 4 open towards the end cover 10 and a second lever (not shown in the figure). The top of the separation component 4 has a through hole 41 through which the moving rod 1 passes. The wall of the through hole 41 has an internal thread (not shown in the figure) that can be threadedly connected to the external thread 14. Because the external thread 14 and the internal thread have a certain self-locking capability, each step of the operation is ensured to be effective until the components are completely separated during the separation of the end cover and rotor assembly, making it more reliable. The separation component 4 has a mounting hole 42 for installing the second lever. Figure 2 As shown, the separator 4 in this embodiment is cylindrical and has a cylindrical chamber 43. The diameter of the chamber 43 is greater than the maximum outer diameter of the end cap 10, and the depth of the chamber 43 is greater than the mounting surface height of the end cap 10.

[0030] The working process of the encapsulated motor separation device in this embodiment is as follows:

[0031] Screw the moving rod 1 into the designated height of the separating part 4, align the rotating shaft 20 with the shaft hole 11 of the moving rod 1 and align the shaft pin 3 on the rotating shaft 20 with the shaft pin groove 13 on the moving rod 1, and then move the moving rod 1 down.

[0032] Until the pin 3 on the rotating shaft 20 reaches the end of the pin groove 13, rotate the moving rod 1 to make the pin 3 engage with the slot 12, and continue to rotate the moving rod 1 so that the moving rod 1 can move along the extension direction of the rotating shaft 20 until the end cover 10 and the rotor assembly b can be separated from the stator assembly a.

[0033] If the required torque is large during the rotation of the moving rod 1, or if the rotation of the moving rod 1 is difficult, the second hand rod can be installed into the mounting hole 42 and rotated in the opposite direction. This can assist the rotation of the moving rod 1, and the end cover 10 and the rotor assembly b can be separated from the stator assembly a, thus achieving the purpose of safely and conveniently disassembling and separating the encapsulated motor.

[0034] In the specification and claims of this utility model, terms indicating direction, such as "front," "rear," "upper," "lower," "left," "right," "side," "top," and "bottom," are used to describe various exemplary structural parts and elements of this utility model. However, the use of these terms is merely for the purpose of explanation and is based on the exemplary orientations shown in the accompanying drawings. Since the embodiments disclosed in this utility model can be arranged in different orientations, these terms indicating direction are for illustrative purposes only and should not be regarded as limitations. For example, "upper" and "lower" are not necessarily limited to directions opposite to or consistent with the direction of gravity.
