[0002] Driven by environmental protection, energy security, and technological advancements, the new energy vehicle industry is developing rapidly. Despite challenges such as range, cost, and technological bottlenecks, its future prospects are broad. The stator is a crucial component of new energy electric vehicles. To ensure product quality, our company has purchased and used vacuum testing equipment. To facilitate employee operation and effectively identify defect locations, we have developed a mechanism for fixing and connecting the stator to generate an electric arc during vacuum testing.

[0003] However, the limiting structure on the stator arc-generating mechanism fixed and connected in the vacuum test cannot adapt to stators of different sizes, so it is necessary to replace the limiting structure with one of different sizes, which is quite inconvenient for users.

[0004] This invention addresses the aforementioned problems by providing a mechanism for fixing and connecting a stator to generate an electric arc during vacuum testing, which is capable of adjusting the limiting structure. Utility Model Content

[0005] The purpose of this invention is to provide a mechanism for fixing and connecting the stator to generate an electric arc in a vacuum test, so as to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a mechanism for fixing and connecting a stator to generate an electric arc in a vacuum test, comprising a connecting base plate and a stator placement platform disposed at the upper side of the connecting base plate;

[0007] An upper connecting and limiting arc-shaped cover is provided on the upper side of the stator placement platform;

[0008] A bottom contact arc-shaped block is provided at the middle position of the bottom side of the upper connecting and limiting arc-shaped cover. A central connecting post is provided at the upper side of the bottom contact arc-shaped block. A limiting lifting groove is provided at the side position of the central connecting post. A second limiting moving guide post and a compression reset spring are provided at the middle position of the limiting lifting groove.

[0011] Preferably, a built-in connecting compression spring is provided inside the plug-in snap-fit ​​block, and a snap-fit ​​ball is provided on the side of the built-in connecting compression spring.

[0012] Preferably, a side compression buckle is provided at the side position of the snap-fit ​​ball, and a limit groove is provided at the side position of the side compression buckle.

[0015] Compared with the prior art, this utility model provides a mechanism for fixing and connecting the stator to generate an electric arc in a vacuum test, which has the following advantages:

[0016] In the stator arc-generating mechanism fixed and connected during vacuum testing, a bottom contact arc-shaped block is provided at the middle position of the bottom side of the upper connecting limit arc-shaped cover. A central connecting post is provided at the upper position of the bottom contact arc-shaped block. A limit lifting groove is provided on the side of the central connecting post.

A first limit moving guide post is provided at the middle position of the limit transverse and longitudinal groove. Pulling the central connecting guide post upwards... The limiting guide post rotates to the top of the limiting horizontal and vertical grooves, keeping the bottom contact arc block in the position of the upper connecting limiting arc cover. When the central connecting guide post rotates to the middle groove of the limiting horizontal and vertical grooves, the central connecting guide post can move the bottom contact arc block downward under the squeezing action of the compression and reset spring. The downward movement of the bottom contact arc block will squeeze and contact the upper surface of the stator placed on the stator placement platform, thereby effectively improving the stability of the stator installation and placement of the stator arc generation mechanism in vacuum testing, and thus effectively improving the practicality of the stator arc generation mechanism in vacuum testing.

The limit horizontal and vertical groove 10 includes a vertical groove and a horizontal groove located at the top.

When the central connecting guide column 8 rotates so that the limiting moving guide column 11 is in the middle vertical groove of the limiting horizontal and vertical groove 10, the central connecting guide column 8 can move the bottom contact arc block 16 downward under the squeezing action of the compression reset spring body 15.

Then, the plug-in locking block 17 will be snapped onto the stator placement platform 4 by the snap-fit ​​ball 19. When disassembly is required, press the side compression buckle 6 to retract the snap-fit ​​ball 19 to complete the disassembly.

[0028] like Figure 1 and Figure 2As shown, a slide rail and its slider 2 are provided at the bottom side of the stator placement platform 4.
