Description

Technical Field

[0001] This utility model relates to the field of motor rust prevention technology, specifically to an oil-immersion rust prevention device for motor stator processing. Background Technology

[0002] The stator is an important component of motors such as generators and starters. It consists of three parts: the stator core, the stator windings, and the frame. The stator's main function is to generate a rotating magnetic field, while the rotor's main function is to be cut by magnetic lines of force within this rotating magnetic field, thereby generating an electric current.

[0003] In order to improve the service life of motor stators, they are usually subjected to oil immersion for rust prevention during the production process. However, the current stator oil immersion process usually involves workers using clamps to hold the stator in the oil and then taking it out. The whole process is cumbersome, increases the workload, and is inefficient. In addition, after the stator is manually removed, a large amount of oil remains on the surface and drips, which has an impact on the environment.

[0004] Therefore, an oil-immersion rust prevention device for motor stator machining that can improve oil immersion efficiency has been designed to address this type of defect. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides an oil-immersion rust prevention device for motor stator processing, which solves the problems of low efficiency and excessive complexity in existing stator oil-immersion rust prevention operations.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an oil-immersion rust-preventing device for motor stator machining, comprising a liquid storage bottom frame, an inner circular plate fixedly connected to the top of the liquid storage bottom frame via a bracket, an outer circular ring plate fixedly connected to the outer periphery of the inner circular plate via a fixing plate, an annular groove provided between the inner circular plate and the outer circular ring plate, a locking seat provided at the top of the inner circular plate, and a plurality of locking seats provided, a vertical guide rod slidably connected to the bottom of the locking seat and slidingly connected to the annular groove, and an L-shaped mounting bracket fixedly connected to the bottom end of the vertical guide rod.

[0007] Preferably, a cylinder is fixedly connected to the top of the inner circular plate through an opening, and a rectangular card frame is fixedly connected to the front end of the cylinder. Side grooves that cooperate with the rectangular card frame are provided on both sides of the card holder. A lifting interface that cooperates with the card holder is provided on the front side of the top of the inner circular plate and the outer circular plate.

[0008] Preferably, the bottom of the L-shaped mounting bracket is provided with a positioning slot, and a lifting rod is slidably mounted on the rear of the L-shaped mounting bracket via a fixing plate. The bottom end of the lifting rod is fixedly connected to a pin that cooperates with the positioning slot via the fixing plate, and a spring is sleeved on the surface of the lifting rod.

[0009] Preferably, a vertical guide plate is fixedly connected to the bottom of the cylinder, and the bottom end of the vertical guide plate passes through the inner circular plate and extends to the lower part of the inner circular plate. The end of the vertical guide plate extending to the lower part of the inner circular plate is fixedly connected to a pressure rod that cooperates with the lifting rod through a bracket.

[0010] Preferably, a slide cylinder frame is slidably mounted on the surface of the vertical guide rod, and a motor is fixedly connected to the bottom of the inner circular plate by a bracket. Several slide cylinder frames are fixedly connected to the output shaft of the motor by a coupling.

[0011] Preferably, the surface of the outer ring plate is fixedly connected to an arc-shaped guide seat that mates with the side groove via a bracket. Beneficial effects

[0012] This utility model provides an oil-immersion rust-preventive device for machining motor stators. Compared with existing technologies, it has the following advantages:

[0013] (1) The oil-immersion rust prevention device for motor stator processing has an annular groove between the inner circular plate and the outer circular plate, and a vertical guide rod and an L-shaped mounting bracket are installed inside the annular groove. It is used in conjunction with a cylinder and a pin. The structure allows the rotation of the motor to replace several L-shaped mounting brackets. Each time the L-shaped mounting bracket is lowered for oil immersion, the pressure rod will lower the pin, making it convenient for workers to replace and install the oil-immersed stator. The whole process does not require too much intervention from the workers, which not only effectively improves the oil immersion efficiency but also reduces the workload.

[0014] (2) The oil-immersion rust prevention device for stator processing of the motor has side grooves on both sides of the clamping seat that are used in conjunction with the arc guide seat. When the L-shaped mounting bracket drives the stator to drain oil, it can continuously shake as it rotates, thereby further shaking off the oil on the surface of the stator, avoiding a large amount of oil dripping when the stator is disassembled, effectively maintaining the surrounding environment and facilitating the use of the staff.

[0021] 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.

[0022] Please see Figure 1-5 This utility model provides a technical solution: an oil-immersion rust prevention device for motor stator processing, including a liquid storage base frame 1, an inner circular plate 2 fixedly connected to the top of the liquid storage base frame 1 by a bracket, an outer circular ring plate 3 fixedly connected to the outer periphery of the inner circular plate 2 by a fixing plate, an annular groove 4 provided between the inner circular plate 2 and the outer circular ring plate 3, a snap-fit ​​seat 5 provided on the top of the inner circular plate 2, and several snap-fit ​​seats 5 are provided, a vertical guide rod 6 slidably connected to the bottom of the snap-fit ​​seat 5 and slidably connected to the annular groove 4, an L-shaped mounting bracket 7 fixedly connected to the bottom end of the vertical guide rod 6, a cylinder 8 fixedly connected to the top of the inner circular plate 2 by opening, a rectangular snap-fit ​​frame 9 fixedly connected to the front end of the cylinder 8, side grooves 16 that cooperate with the rectangular snap-fit ​​frame 9 are provided on both sides of the snap-fit ​​seat 5, the side grooves 16 can indirectly allow the arc-shaped guide seat 19 to pass through, and a lifting interface 20 that cooperates with the snap-fit ​​seat 5 is provided on the front side of the top of the inner circular plate 2 and the outer circular ring plate 3.

[0023] In use, first inject rust-preventive oil into the interior of the liquid storage base frame 1, then start the cylinder 8 to descend, causing the pressure rod 15 to press the lifting rod 11 and drive the pin 12 to be pulled out from the inside of the positioning slot 10. Then, the operator places the stator inside the first L-shaped mounting bracket 7 on the right. Then, start the cylinder 8 to rise, causing the pin 12 to rise through the spring force of the spring 13 to limit the stator. Then, start the motor 17 and use the slide frame 18 to drive several vertical guide rods 6 to rotate inside the annular rotating groove 4 until the snap-fit ​​seat 5 connects with the rectangular snap-fit ​​frame 9 through the side groove 16. At this time, the snap-fit ​​seat 5 is located inside the lifting interface 20. Then, the cylinder 8 descends again, which will push the L-shaped mounting bracket 7 and the stator down into the interior of the liquid storage base frame 1 for oil immersion.

[0024] Furthermore, the bottom of the L-shaped mounting bracket 7 is provided with a positioning slot 10. A lifting rod 11 is slidably mounted on the rear of the L-shaped mounting bracket 7 via a fixing plate. The bottom end of the lifting rod 11 is fixedly connected to a pin post 12 that cooperates with the positioning slot 10 via a fixing plate. A spring 13 is sleeved on the surface of the lifting rod 11. A vertical guide plate 14 is fixedly connected to the bottom of the cylinder 8, and the bottom end of the vertical guide plate 14 penetrates the inner circular plate 2 and extends to the lower part of the inner circular plate 2. The end of the vertical guide plate 14 extending to the lower part of the inner circular plate 2 is fixedly connected to a bracket. There is a pressure rod 15 that works in conjunction with the lifting rod 11. A slide frame 18 is slidably mounted on the surface of the vertical guide rod 6. The slide frame 18 consists of a slide and an external frame, which allows the vertical guide rod 6 to be raised and lowered inside the slide frame 18. A motor 17 is fixedly connected to the bottom of the inner circular plate 2 by a bracket. The motor 17 is a servo motor. Several slide frames 18 are fixedly connected to the output shaft of the motor 17 by a coupling. An arc-shaped guide seat 19 that works in conjunction with the side groove 16 is fixedly connected to the surface of the outer circular plate 3 by a bracket.

[0025] As cylinder 8 descends to immerse the stator in oil, the pin 12 inside the L-shaped mounting bracket 7 on its right side descends. The operator continues to install the stator. After immersion, cylinder 8 drives the soaked stator to rise, and motor 17 continues to drive several L-shaped mounting brackets 7 to rotate for switching. As the snap-fit ​​seat 5 rotates, the arc-shaped guide seat 19 abuts against the side groove 16, causing the vertical guide rod 6 to drive the L-shaped mounting bracket 7 to shake up and down, draining and drying the stator inside the L-shaped mounting bracket 7 until the L-shaped mounting bracket 7 rotates back to the right side, driving the pin 12 to descend again, and then the stator is replaced.

[0026] Furthermore, any content not described in detail in this specification is existing technology known to those skilled in the art.
