Description

Technical Field

[0001] This utility model belongs to the technical field of segmented stator laser welding fixtures, specifically relating to a segmented stator laser welding fixture. Background Technology

[0002] The segmented stator laser welding fixture is a mechanical device specifically designed for the laser welding process of segmented stators. Through physical structures such as an adaptive mechanical centering mechanism and a linkage multi-jaw clamping cam mechanism, it achieves high-precision radial centering, circumferential positioning, and uniform clamping of the stator segments. At the same time, with the help of mechanical heat dissipation channels and quick-release anti-spatter guards, it solves the problems of heat accumulation and spatter damage during welding, ensuring the stability of the stator segment position and the reliability of the fixture performance during laser welding, thereby guaranteeing the welding accuracy and quality at the joints of the segmented stators.

[0003] The outer diameter positioning cage needs to be installed through the top mounting plate. The core operation during installation is to accurately align the through holes on the top mounting plate with the corresponding external through holes. However, because there are many through holes that need to be aligned, it takes a lot of time for operators to complete the alignment process. This situation directly prolongs the installation time of the outer diameter positioning cage. Therefore, the market needs a new device to solve the current problems. Utility Model Content

[0004] The purpose of this invention is to provide a segmented stator laser welding fixture to solve the problem mentioned in the background art that the outer diameter positioning squirrel cage needs to be installed through a top mounting plate. The core operation during installation is to accurately align the through holes on the top mounting plate with the corresponding external through holes. However, because there are many through holes that need to be aligned, it takes a lot of time for the operator to complete the alignment process. This situation directly prolongs the installation time of the outer diameter positioning squirrel cage. Therefore, the market needs a new device to solve the current problems.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a segmented stator laser welding fixture, comprising a top mounting plate, an outer diameter positioning cage mounted at the lower end of the top mounting plate, a segmented stator body disposed on the inner wall of the outer diameter positioning cage, a stator winding disposed at the front end of the segmented stator body, a positioning inner diameter center column for positioning disposed inside the outer diameter positioning cage, a second mounting hole disposed at the upper part of the inner side of the outer diameter positioning cage, the second mounting hole communicating with a first mounting hole disposed inside the top mounting plate, and an elastic positioning pin sleeved inside the first mounting hole.

[0006] Preferably, a passageway is provided at the internal position of the outer diameter positioning cage.

[0007] Preferably, the through hole located at the lower part of the outer diameter positioning cage is at the same horizontal line as the second mounting hole.

[0008] Preferably, a protrusion is provided at the lower middle position of the outer diameter positioning cage.

[0009] Preferably, the outer diameter positioning cage is installed with an external device via a top mounting plate.

[0010] Preferably, the elastic locating pin can be compressed into the interior position of the first mounting hole.

[0011] Preferably, the fixing plates located on both sides of the outer wall of the elastic positioning pin are located in the groove inside the top mounting plate.

[0012] Preferably, a stainless steel spring is fixed at the lower end of the fixing plate.

[0013] Compared with the prior art, this utility model provides a segmented stator laser welding fixture, which has the following advantages: An elastic positioning pin is pre-installed inside the first mounting hole of the top mounting plate. This positioning pin is assembled with a stainless steel spring. When installing the outer diameter positioning cage, the operator does not need to calibrate all the through holes one by one. He only needs to bring the top mounting plate close to the external mounting structure. At this time, the elastic positioning pin in the first mounting hole will automatically pop out under the elastic force of the stainless steel spring and accurately lock into the corresponding external mounting hole. This quickly completes the initial positioning of the top mounting plate and the external structure. Through the pure mechanical cooperation of the elastic positioning pin and the stainless steel spring, the tedious step of aligning multiple through holes one by one is skipped, which greatly shortens the alignment time between the top mounting plate and the external structure and significantly improves the installation efficiency of the outer diameter positioning cage.

[0014] First, the segmented stator is tightly attached to the positioning inner diameter center column, and the lower frame is inserted into the groove to ensure the inner diameter accuracy. The segmented stator and the inner diameter center column are pressed into the outer diameter positioning cage using a press. Then, laser welding can be performed on the weld seam along the exposed part of the outer diameter positioning cage. This can be used to improve the consistency of the laser welding state of the segmented stator, and improve product quality and work efficiency. Attached Figure Description

Detailed Implementation

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0021] In the description of this utility model, it should be noted that the terms "upper," "lower," "inner," "outer," "front end," "rear end," "both ends," "one end," and "the other end," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are used only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model. In addition, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0022] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installed," "equipped with," and "connected," etc., should be interpreted broadly. For example, "connected" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium; it can be a connection within two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances. The utility model provides, for example Figure 1-4The illustrated segmented stator laser welding fixture includes a top mounting plate 1, an outer diameter positioning cage 4 mounted at the lower end of the top mounting plate 1, a segmented stator body 2 disposed on the inner wall of the outer diameter positioning cage 4, a stator winding 5 disposed at the front end of the segmented stator body 2, a positioning inner diameter center column 3 disposed inside the outer diameter positioning cage 4 for positioning, a second mounting hole 12 disposed at the upper part of the inner side of the outer diameter positioning cage 4, the second mounting hole 12 communicating with a first mounting hole 7 disposed inside the top mounting plate 1, and an elastic positioning pin 6 sleeved inside the first mounting hole 7.

[0023] When using the segmented stator laser welding fixture, the segmented stator must first be tightly fitted to the positioning inner diameter center column 3, and the frame below the segmented stator should be inserted into the corresponding slot to ensure the inner diameter accuracy. Then, the fitted segmented stator and the positioning inner diameter center column 3 are pressed together into the outer diameter positioning cage 4 using a press to complete the precise positioning of each component. Finally, the weld seam of the segmented stator can be laser welded along the exposed part of the outer diameter positioning cage 4 to ensure the welding quality and consistency.

[0024] like Figure 1 and Figure 3 As shown, a through groove 14 is provided inside the outer diameter positioning cage 4. The through hole 8 at the lower part of the outer diameter positioning cage 4 is at the same horizontal line as the second mounting hole 12. A protrusion 13 is provided at the middle of the lower end of the outer diameter positioning cage 4. The outer diameter positioning cage 4 is installed with the external device through the top mounting plate 1. The elastic positioning pin 6 can enter the inner position of the first mounting hole 7 when squeezed. The fixing plates 9 on both sides of the outer wall of the elastic positioning pin 6 are located in the sliding groove 10 inside the top mounting plate 1. A stainless steel spring 11 is fixed at the lower end of the fixing plate 9.

[0025] When the elastic positioning pin 6 is compressed, the fixing plate 9 moves inside the slide groove 10. As the slide groove 10 moves, it compresses the stainless steel spring 11. After the compression force is removed, the stainless steel spring 11 releases its elastic force, which bounces the elastic positioning pin 6 outward.

[0026] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present 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. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
