Description

Device for separating motor test assembly

Technical Field

The present disclosure relates to a device for separating motor test assemblies

Background

The motor driving system is an important component of a power system of the pure electric vehicle or the hybrid electric vehicle. As part of the electric motor drive system, the electric motor has the task of efficiently converting the energy of the battery into kinetic energy of the entire vehicle or feeding it back into the battery under the control of the driver.

In order to make an electric automobile have good use performance, a driving motor should have a wider speed regulation range, a higher rotating speed and enough starting torque, and also has the performances of small volume, light weight, high efficiency, strong dynamic braking performance and energy feedback. Therefore, the motor plays an important role in the motor drive system.

In recent years, the production and sales of electric vehicles are continuously increased, which inevitably drives the continuous increase of the production of the electric motor, and the electric motor needs to be tested after being produced, including the test of basic parameters and the environmental test. For some environmental tests, the motor shaft needs to be sealed and protected to prevent the motor shaft from rusting. A sealing member (e.g., a seal ring made of rubber, etc.) is generally used to connect the shaft end of the motor, thereby securing the sealability of the motor shaft. However, during testing, as the temperature changes, the seal, such as a rubber seal, may deform or soften, causing the seal to become highly bonded to the end of the motor shaft, making it difficult to remove the seal after testing the motor. The conventional method is a violent disassembly using a tool such as a screwdriver or the like to pry the seal, but this method not only requires much effort of an operator, but also has a high possibility of damaging the outer surface of the motor.

Therefore, a motor sealing element dismounting tool needs to be designed, which can not only enable the motor to keep stable in the sealing element dismounting process, but also enable the motor sealing element to be dismounted easily.

SUMMERY OF THE UTILITY MODEL

Therefore, it is an object of the present disclosure to provide a device for separating a motor test assembly, which not only facilitates the removal of the motor seal for the test process, but also keeps the motor stable throughout the process of removing the seal, thus ensuring that the motor is not damaged. In addition, the device has the advantages of simple structure, easy disassembly and assembly, high flexibility and lower cost.

Various embodiments of an apparatus for separating motor test assemblies according to embodiments of the present disclosure are described in detail below with reference to fig. 1 to 3.

As shown in fig. 1, a motor test assembly according to the present disclosure may include a motor 1 and an adapter 2 sealingly fitted to a driving end of the motor. The electric machine 1 can be an electric motor to be tested, a generator or the like. The driving end of the motor refers to the end of the motor where the motor shaft or the output shaft of the motor is located, and is the power output end, and the gear and the coupling can be installed at the end. And the motor non-driving end corresponds to the motor driving end.

Furthermore, the motor test assembly according to the present disclosure may further comprise means for separating the motor test assembly, which means comprise the support means 3 and the separating means 4. The motor test assembly described above is supported and fixed to the support means 3. For example, the support means 3 may be constituted by a plurality of cross beams, such as aluminum alloy beams or the like. The separating means 4 is supported and fixed to the supporting means 3 and is able to apply a separating force to the adaptor 2. After the separation device 4 applies a separation force to the adapter 2, the adapter 2 can be separated from the drive end of the motor, thereby enabling removal of the motor seal for the testing process.

As shown in fig. 2 and 3, the supporting device 3 includes a base 5, a supporting block 6, and a motor fixing block 7. A support block 6 is mounted to the base 5 to support the motor test assembly described above. The motor fixing block 7 is detachably mounted to the base 5 and detachably connected to the motor 1 to be tested described above.

For example, the motor fixing block 7 is detachably connected to the motor 1 by bolts. As shown in fig. 2, the motor fixing block 7 is provided with a bolt mounting hole aligned with the hole of the motor 1 to be tested. Of course, the present disclosure is not limited to the fixing by the bolt, and any fixing is applicable.

In addition, the support device 3 further comprises a separating device fixing block 8, and the separating device fixing block 8 is mounted to the base 5. The separating device 4 is, for example, a puller device. In particular, the puller device may comprise a puller claw 41, a puller seat 42, a screw 43 and a rocker 44, wherein the puller claw 41 is snap-fitted to the adaptor 2 to be able to apply a separating force to the adaptor 2. The number of puller claws 41 is not limited to two shown in fig. 2 and 3. The rotation of the rocker 44 controls the advance and retreat of the screw 43, so that the detachment force is applied to the adaptor 2 by the puller claw 41, thereby detaching the adaptor 2 from the motor 1. The above structure makes the removal of the motor sealing member easy without damaging the motor 1. Of course, the separation device of the present disclosure may have other forms, for example, hydraulic, pneumatic, automatic separation devices.

To enable adaptation to motors of different designs or different sizes, the support block 6 is slidably mounted to the base 5. For example, the support block 6 may comprise two

slides

61, 62 forming a V-shaped support structure, and a bottom support slide 63. For example, the base 5 is provided with guide rails for the two

sliders

61, 62. By moving the two

slides

61, 62 and/or the bottom support slide 63 forming the V-shaped support structure in the longitudinal direction of the base, motors of different designs or different sizes can be supported on the base 5. The longitudinal direction of the base is consistent with the extending direction of the motor or the extending direction of the output shaft of the motor. For example, supportable portions of differently designed motors may be located at different positions of the motor, and thus the positions of the two

slides

61, 62 and/or the bottom support slide 63 forming the V-shaped support structure need to be adjusted to achieve stable support. In other examples of the disclosure, the individual slides of the support block 6 may be replaced to accommodate motors of different designs or different sizes. Of course, the bottom support slide 63 may also be replaceable.

Referring to fig. 1 and 2, the motor mount block 7 is located near the non-drive end of the motor 1, and the separator mount block 8 is located near the drive end of the motor 1. In this way, it can be ensured that the motor remains stable throughout the process of removing the adapter 2, i.e. the motor seal, thus further ensuring that the motor is not damaged.

As shown in fig. 2 and 3, the separating device fixing block 8 includes a vertical supporting block 81 and an inclined supporting block 82, and the vertical supporting block 81 and the inclined supporting block 82 form a triangular connection. Therefore, the separating device fixing block 8 can ensure the stability of the separating device, and further ensure that the motor is always stable in the process of disassembling the motor sealing element.

As can be seen from the foregoing, the apparatus for separating a motor test assembly according to the present disclosure not only facilitates the removal of the motor seal for the test process, but also keeps the motor stable all the time during the removal of the seal, thereby ensuring that the motor is not damaged. In addition, the device for separating the motor test assembly is simple in structure, easy to disassemble and assemble, high in flexibility and low in cost.

The above-disclosed technical features are not limited to the combinations with other features disclosed, and other combinations between the technical features can be made by those skilled in the art according to the purpose of the present disclosure, so as to achieve the purpose of the present disclosure.
