Abstract
Description
Technical Field
[0001] This utility model relates to the field of stator assembly sealing ring processing technology, and in particular to an auxiliary tooling for attaching sealing rings to stator assemblies. Background Technology
[0002] In electric motors, stator assemblies typically require the installation of sealing rings to prevent dust, moisture, or other contaminants from entering the motor, thereby protecting the motor's insulation and mechanical components.
[0003] Chinese patent CN117103177A discloses an auxiliary tooling and electrostatic chuck system for installing a sealing ring. The system includes a main body matched with an electrostatic chuck, N support parts located on the main body, and a lifting part. The N support parts are arranged in a ring to support the sealing ring from the inside, ensuring that the axial direction of the sealing ring between two adjacent support parts is perpendicular to the radial direction of the groove in the electrostatic chuck. Upon pressing, the upper and lower edges of the sealing ring between two adjacent support parts simultaneously enter the groove. The lifting part, located on the main body, drives the main body axially away from the electrostatic chuck, thereby disengaging the support parts from the sealing ring. This invention, by adjusting the relative position of the sealing ring and the groove, ensures that the upper and lower edges of the sealing ring can simultaneously enter the groove during pressing installation, thus achieving successful installation of the sealing ring.
[0004] However, this technical solution uses a slot to install the sealing ring. During the installation process, inaccurate positioning may occur, causing the sealing ring to fail to be accurately embedded in the slot, which may damage the sealing ring and affect the sealing effect. Utility Model Content

[0026] Example
[0027] like Figures 1-3As shown, this embodiment provides an auxiliary tooling for attaching sealing rings to a stator assembly, including: a base plate 1, a plurality of guide rods 2 evenly distributed on the base plate 1 and slidably connected to the base plate 1, and a pressing component 3 disposed in the middle of the base plate 1. The guide rods 2 are disposed on the outer periphery of the pressing component 3, and a plurality of sealing rings to be attached are sequentially installed on the lower part of the guide rods 2. The pressing component 3 drives the base plate 1 to move up and down reciprocally. The base plate 1 serves as the foundation of the entire tooling, providing stable support. The evenly distributed guide rods 2 and slidably connected to the base plate 1 can ensure that the sealing rings are precisely aligned during the attachment process, improving assembly accuracy. That is, the guide rods 2 are used to fix and position the sealing rings, ensuring that the sealing rings maintain the correct position during the attachment process. The pressing component 3 is used to apply pressure to ensure that the sealing rings can be evenly and firmly attached to the end face of the stator assembly. It is simple to operate, easy to control, and convenient to use.
[0028] The pressing assembly 3 includes: a central rod 31 passing through the center of the base plate 1; a handle 32 sleeved on the upper outer periphery of the central rod 31 and fixedly connected to the base plate 1; an elastic element 33 disposed at the lower part of the central rod 31; and a fixing block 34 disposed below the elastic element 33 and fixedly connected to the bottom of the central rod 31. The elastic element 33 can buffer pressure, ensure uniform pressure distribution, and prevent the sealing ring from being crushed. The fixing block 34 can limit the position of the elastic element 33, preventing it from detaching from the central rod 31, so as to ensure that the elastic element 33 can work normally and thus transmit pressure evenly and stably to the sealing ring. The sealing ring is preferably made of a flexible material. The fixing block 34 and the central rod 31 are preferably threadedly connected. The fixing block 34 is a nut, and the bottom of the central rod 31 is a screw. The handle 32 can be fixed to the base plate 1 by bolts.
[0029] Meanwhile, the center rod 31 is fixedly connected to the base plate 1 by a locking member 35, and the locking member 35 is located inside the handle 32. The locking member 35 is used to fix the center rod 31 and the base plate 1, ensuring that the center rod 31 will not move during operation and ensuring the stability of the entire tooling.
[0030] In this embodiment, the locking member 35 and the base plate 1 are fixedly connected by a plurality of fasteners 36. The fasteners 36 are used to further fix the locking member 35 and the base plate 1, enhance the firmness of the connection, and thus ensure the stability of the entire tooling. The design of the fasteners 36 allows for adjustment when necessary, improving the flexibility of the tooling. The fasteners 36 are preferably bolts.
[0031] In this embodiment, an elastic element 33 is provided between the locking member 35 and the fixing block 34. The elastic element 33 is preferably a return spring, which is sleeved on the lower part of the center rod 31 and installed between the locking member 35 and the fixing block 34. The elastic element 33 ensures that the sealing ring can be evenly and firmly attached to the stator assembly, improving the assembly quality. The elastic element 33 can automatically reset to allow for the installation of the next sealing ring. It does not require much manual operation, is convenient to use, and has high installation efficiency.
[0032] In this embodiment, a blocking block 37 is provided at the top of the center rod 31. The blocking block 37 is located close to the top of the handle 32, which can prevent the handle 32 from disengaging from the center rod 31 due to the reset of the elastic element 33, and plays a limiting and blocking role. The blocking block 37 and the center rod 31 can preferably be threadedly connected. The blocking block 37 is a nut, and the top of the center rod 31 is a screw.
[0033] In this embodiment, the bottom of the guide rod 2 is provided with a connecting rod 21 for installing the sealing ring. The connecting rod 21 is used to install the sealing ring and ensure that the sealing ring maintains the correct position during the pasting process. The guide rod 2 and the connecting rod 21 are stepped, which facilitates the installation and positioning of the sealing ring and ensures that the sealing ring can be accurately pasted onto the stator assembly, achieving precise alignment and improving assembly accuracy.
[0034] Of course, the diameter of the guide rod 2 is larger than the diameter of the connecting rod 21. The bottom surface of the connecting rod 21 abuts against the stator assembly. The upper end surface of the stator assembly and the lower end surface of the guide rod 2 can just accommodate a sealing ring. Then, the release paper on the sealing ring is torn off, and the guide rod 2 is inserted into the mounting holes on the stator assembly one by one. The sealing ring is then pasted onto the end face of the stator assembly.
[0035] In addition, a limit block 22 is provided at the top of the guide rod 2 to prevent the guide rod 2 from completely detaching from the base plate 1, thereby limiting its position and ensuring that the tooling can work normally. The guide rod 2 and the limit block 22 are preferably connected by a thread, the top of the guide rod 2 is a screw, and the limit block 22 can be a nut.
[0036] The working process of this embodiment is as follows: First, install multiple sealing rings sequentially onto the lower part of the guide rod 2, and peel off the release paper on the bottom layer of the sealing ring. Then, insert the guide rod 2 into the positioning holes on the stator assembly one by one, flatten the base plate 1, and then press down the handle 32. Under the action of the elastic element 33, the handle 32 will drive the base plate 1 to move down, and the base plate 1 will continue to squeeze the sealing rings until the bottom layer of the sealing ring just moves onto the connecting rod 21. At this time, the subsequent sealing rings will not move down onto the connecting rod 21 due to the obstruction of the bottom layer of the sealing ring. Then, continue to press the handle 32 to stick the sealing ring onto the end face of the stator assembly. After sticking, release the handle 32, the elastic element 33 will automatically reset, and drive the base plate 1 to move up. Finally, take out the tooling to install the next stator assembly sealing ring.
[0037] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
