Description

Technical Field

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

[0002] In layman's terms, the motor rotor is the rotating part of a motor; it's also the rotating component. A motor consists of two parts: the rotor and the stator. It's a device used to convert electrical energy into mechanical energy and vice versa. Motor rotors are divided into electric motor rotors and generator rotors, and further categorized into two types based on their rotation mechanism: internal rotor and external rotor. In an internal rotor rotor, the core of the motor is the rotating body, outputting torque (for an electric motor) or receiving energy (for a generator). In an external rotor rotor rotor, the outer body of the motor is the rotating body. These different methods facilitate applications in various situations.

[0003] The existing publication number CN218387191U discloses a jig for disassembling an external rotor motor rotor, which aims to solve the problem of how to quickly disassemble the motor rotor without damaging other motor components. The jig includes a jig body, which includes a work plate with a pressure needle working hole. The work plate has a motor disassembly block on its lower side. The motor disassembly block is U-shaped and has a disassembly protrusion on its inner side. When the motor to be disassembled is placed in the U-shaped groove of the motor disassembly block, the disassembly protrusion supports the motor housing. Then, the positioning pressure needle applies pressure to the inside of the motor through the pressure needle working hole, so that the motor housing is separated from the internal structure of the motor.

[0004] While existing technology allows for the separation of the housing from the motor, it cannot effectively disassemble the motor rotor, as shown in the attached diagram. Figure 6 It is known that the disassembly of the motor rotor not only requires separation from the housing, but also consideration of the gear at one end of the rotor shaft. Direct stamping cannot effectively disassemble the rotor. Therefore, we propose a motor rotor disassembly fixture. Utility Model Content

[0005] The purpose of this invention is to provide a motor rotor disassembly tool to solve the problems in the prior art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a motor rotor disassembly fixture, comprising a base, a jig, and a disassembly shim. The base has a jig and a column mounted on its top. The column is adjustablely mounted with a pressing component, which includes a punch that acts on the shaft of the motor rotor. The jig is an annular cylindrical structure with an inner annular step inside. The jig has a first step at its top and a second step at the middle of the first step. The disassembly shim has a groove at at least one end that mates with the shaft of the motor rotor.

[0007] Preferably, the pressing assembly includes a base, on which a lifting rod is adjustablely mounted, and a pressing rod for driving the lifting rod is also mounted on the base, with the punch fixed to the bottom end of the lifting rod.

[0008] Preferably, the base has a groove for installing the lifting rod, and a limit plate is installed on one side of the base near the lifting rod. One side of the lifting rod is configured with a toothed structure, and the pressing rod is installed in the base with a gear that meshes with the toothed structure.

[0009] Preferably, a bracket is installed on the top of the base, and a tension spring is installed between the bracket and the lifting rod.

[0010] Preferably, the fixture is fixed to the base by bolts.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] 1.

[0022] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model. Therefore, the following detailed description of the embodiments of this utility model provided in the accompanying drawings is not intended to limit the scope of the claimed utility model, but merely to represent selected embodiments of this utility model.

[0023] Please see Figure 1-6 In this embodiment of the present invention, a motor rotor disassembly fixture includes a base 1, a jig 10, and a disassembly pad 11. The jig 10 and a column 2 are mounted on the top of the base 1. A pressing component is adjustablely mounted on the column 2. The pressing component includes a punch 9 that acts on the shaft of the motor rotor. The pressing component drives the punch 9 to press down, thereby the punch 9 acts on the shaft of the rotor, thereby achieving the disassembly of the rotor.

[0024] The fixture 10 is fixed to the base 1 by bolts. The fixture 10 is an annular cylindrical structure. The fixture 10 has an inner annular step 101 inside. The inner annular step 101 is used to support the annular structure of the housing near the rotor, thereby improving the support effect on the housing. The top of the fixture 10 has a first step 102, and the middle of the first step 102 has a second step 103. Both the first step 102 and the second step 103 are designed to fit the shape of the housing.

[0025] The pressing assembly includes a base 3, on which a lifting rod 6 is adjustablely mounted. The base 3 also has a pressing rod 7 that drives the lifting rod 6. The punch 9 is fixed to the bottom end of the lifting rod 6. The base 3 has a slot for mounting the lifting rod 6, and a limiting plate 8 is installed on one side of the base 3 near the lifting rod 6. One side of the lifting rod 6 has a toothed structure. The pressing rod 7 has a gear inside the base 3 that meshes with the toothed structure. The pressing rod 7 drives the lifting rod 6 downwards, thereby driving the punch 9 to act on the rotor shaft. A bracket 4 is installed on the top of the base 3. A tension spring 5 is installed between the bracket 4 and the lifting rod 6. After disassembly, the tension of the tension spring 5 drives the lifting rod 6 upwards, thus not affecting subsequent disassembly operations.

[0026] The disassembly shim 11 has a groove at at least one end that mates with the shaft of the motor rotor. The disassembly shim 11 can be locked between the housing and the gear, thereby blocking the gear and preventing the gear from directly impacting the housing during stamping and causing damage to the housing.

[0027] The working principle of this utility model is as follows: the pressing assembly includes a punch 9 that acts on the shaft of the motor rotor; the pressing assembly drives the punch 9 to press down, so that the punch 9 acts on the shaft of the rotor, thereby realizing the disassembly of the rotor; the disassembly shim 11 has a groove at at least one end that cooperates with the shaft of the motor rotor, and the disassembly shim 11 can be stuck between the housing and the gear, thereby blocking the gear and preventing the gear from directly hitting the housing during the pressing process and causing damage to the housing.

[0028] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
