An anti-oxidation surface treatment device for plastic-encapsulated motor stator core

Abstract

This utility model discloses an anti-oxidation surface treatment device for the stator core of a plastic-encapsulated motor. It includes a base, a motor-driven clamping assembly mounted on one side of a set of columns, the clamping assembly including a driver and a clamp, the clamp being rotated by a rotating component, and a storage cavity fixedly mounted on the top of the base. A nozzle is located at the top of the storage cavity. By starting the motor, a bidirectional screw is rotated, causing two sets of nut seats to move in opposite directions, bringing the two sets of positioning frames closer together. This allows the two sets of turntables to clamp and position the stator core. The anti-rust paint in the storage cavity is atomized and sprayed out through the nozzle. Then, the drive motor is started again, driving one set of turntables to rotate via a connecting rod. Because the two sets of turntables clamp the stator core, the rotation of the turntables also causes the stator core to rotate. This not only achieves automatic spraying but also controls the speed of the drive motor, ensuring a more uniform application of the anti-rust paint to the surface of the stator core.

Description

Technical Field

[0001] This utility model relates to the field of processing technology for stator cores of encapsulated motors, specifically to an anti-oxidation surface treatment device for stator cores of encapsulated motors. Background Technology

[0002] In the motor manufacturing industry, the stator core is a core component of the motor, and its performance directly affects the motor's efficiency, energy consumption, and lifespan. The stator core is typically made of laminated high-permeability silicon steel sheets, but this material is highly susceptible to chemical reactions with oxygen and water vapor in the air, leading to surface oxidation and rust formation. Oxidation not only affects the core's appearance but also reduces its permeability and increases iron losses, resulting in decreased motor efficiency, excessive temperature rise, and ultimately, a shortened motor lifespan.

[0003] To prevent oxidation, traditional processes typically involve surface treatment of the stator core. Currently, the most common surface treatment method is spraying anti-rust paint. However, most current spraying equipment involves hoisting the stator core and then manually moving the spray gun to apply the paint. Because the stator core is fixed in place, it is difficult for the spray gun to form a uniform and complete protective film in the tiny gaps between the core laminations, resulting in incomplete oxidation. Furthermore, since anti-rust paint is quite harmful to the human body, even with masks, long-term exposure can still pose significant health risks to operators. Therefore, it is necessary to design an anti-oxidation surface treatment device for encapsulated motor stator cores to solve these problems. Utility Model Content

[0004] The purpose of this invention is to provide an anti-oxidation surface treatment device for the stator core of a plastic-encapsulated motor, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an anti-oxidation surface treatment device for a plastic-encapsulated motor stator core, comprising a base, two sets of columns fixedly provided on the top of the base, and an adjustment motor driving clamping assembly displaced on one side of one set of columns, the clamping assembly comprising a driver and a clamp, the clamp being driven to rotate by a rotating assembly; It also includes a storage chamber fixedly installed on the top of the base, and the top of the storage chamber is provided with a nozzle.

[0006] Preferably, the driver includes an adjusting motor mounted on the top of a set of columns. The output end of the adjusting motor passes through the column and is fixedly connected to a bidirectional screw. The bidirectional screw is rotatably mounted between two sets of columns. The external thread of the bidirectional screw is connected to two sets of nut seats, and a positioning frame is fixedly connected to the bottom of the nut seats.

[0007] Preferably, the clamp includes a turntable rotatably mounted on the front end of the positioning frame via a connecting rod, and a buffer pad is provided on the outer side of the turntable.

[0008] Preferably, the rotating assembly includes a gear slot formed on the outer surface of a set of turntables, a transmission gear meshing in the gear slot, the transmission gear being connected to a drive motor via a connecting shaft, and the drive motor being mounted on the outside of a set of positioning frames.

[0009] Preferably, the outer sides of the two sets of positioning frames are fixedly connected to one end of the telescopic rod, and the other end of the telescopic rod is fixed to the inner side of the column.

[0010] Compared with the prior art, the beneficial effects of this utility model are: 1. In this utility model, by starting the adjusting motor, the bidirectional screw is driven to rotate, thereby causing the two sets of nut seats to move in opposite directions, thus bringing the two sets of positioning frames closer together. This allows the two sets of turntables to clamp and position the stator core. Furthermore, a buffer pad is provided on the inner side of the turntable to provide soft clamping for the stator core, preventing damage to the stator core caused by rigid clamping. The anti-rust paint in the storage cavity is atomized and sprayed out through nozzles. At this time, the drive motor is started again to drive one set of turntables to rotate through the connecting rotating rod. Since the two sets of turntables clamp the stator core, the rotation of the turntables also drives the stator core to rotate. This not only enables automatic spraying but also controls the speed of the drive motor, ensuring that the anti-rust paint sprayed on the surface of the stator core is more uniform.

[0013] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0014] Example 1

[0015] Please refer to Figure 1-2 As shown, this utility model provides an anti-oxidation surface treatment device for the stator core of a plastic-encapsulated motor, including a base 1, two sets of columns 2 fixedly provided on the top of the base 1, and an adjustment motor 6 installed on one side of one set of columns 2 to drive the clamping assembly to move. The clamping assembly includes a driver and a clamp, which is driven to rotate by a rotating assembly. It also includes a storage cavity 14 fixedly provided on the top of the base 1, and a nozzle 15 is provided on the top of the storage cavity 14.

[0016] Specifically, the driver includes an adjusting motor 6 mounted on the top of a set of columns 2. The output end of the adjusting motor 6 passes through the column 2 and is fixedly connected to a bidirectional screw 5. The bidirectional screw 5 is rotatably mounted between the two sets of columns 2. The external threads of the bidirectional screw 5 are connected to two sets of nut seats 7. The bottom of the nut seats 7 is fixedly connected to a positioning frame 4. The clamp includes a turntable 9 rotatably mounted on the front end of the positioning frame 4 via a connecting rotating rod 8. A buffer pad is provided on the outer side of the turntable 9. The rotating component includes a gear groove 10 opened on the outer surface of the turntable 9. A transmission gear 11 meshes in the gear groove 10. The transmission gear 11 is connected to the drive motor 13 via a connecting rotating shaft 12. The drive motor 13 is mounted on the outer side of the positioning frame 4. The outer sides of the two sets of positioning frames 4 are fixedly connected to one end of the telescopic rod 3. The other end of the telescopic rod 3 is fixed to the inner side of the column 2.

[0017] Specifically: by starting the regulating motor 6, the bidirectional screw 5 is driven to rotate, thereby causing the two sets of nut seats 7 to move in opposite directions, thereby causing the two sets of positioning frames 4 to move closer to each other, and causing the two sets of turntables 9 to clamp and position the stator core. In addition, the inner side of the turntable 9 is also equipped with a buffer pad, which can softly clamp the stator core and avoid damage to the stator core caused by rigid clamping. Furthermore, the anti-rust paint in the storage cavity 14 is atomized and sprayed out through the nozzle 15. At this time, the drive motor 13 is started and drives a set of turntables 9 to rotate through the connecting rod 8. Since the two sets of turntables 9 clamp the stator core, the rotation of the turntables 9 also drives the stator core to rotate. This not only enables automatic spraying, but also controls the speed of the drive motor 13, making the anti-rust paint sprayed on the surface of the stator core more uniform.
