Description

Technical Field

[0001] This invention relates to the field of flipping devices, and more particularly to an automatic flipping device for a motor. Background Technology

[0002] Currently, after the production and assembly of large motors are completed, a liquid tightness test is required inside the motor. After the test, a crane is used to lift the large motor, and then it is manually tilted to empty the internal liquid. However, this method is prone to slippage, shaking, or crane imbalance, leading to injuries, collisions, or liquid splashing. Furthermore, it is inefficient and incompletely drains the liquid, requiring multiple people and repeated adjustments, which is time-consuming and labor-intensive, and it is difficult to completely remove all residual liquid. Thirdly, the tilting process may damage the motor casing or internal components due to collisions, and frequent lifting increases crane wear. Finally, liquid spillage may affect ground safety and increase cleanup costs. Overall, this method is labor-intensive, lacks controllability, and presents significant safety hazards and operational bottlenecks. Summary of the Invention

[0026] Furthermore, the technical features involved in the different embodiments of this application described below can be combined with each other as long as they do not conflict with each other.

[0027] The preferred embodiments of the present invention will now be further described with reference to the accompanying drawings, such as... Figure 1 As shown, an automatic flipping device for a motor includes an L-shaped bracket 10, a support plate 11 vertically mounted on the bracket 10, a rotating shaft 12 extending through the support plate 11, a connecting assembly 100 at one end of the rotating shaft 12, a motor body 200 detachably mounted on the connecting assembly 100, and a drive assembly 300 mounted on the side of the rotating shaft 12 away from the connecting assembly 100. The drive assembly 300 drives the rotating shaft 12 to rotate, causing the connecting assembly 100 to drive the motor body 200 to rotate around the rotating shaft 12 as an axis.

[0028] This application pertains to supporting equipment for the production and testing of motors, particularly for testing the airtightness of the liquid inside a motor. In the working state of this application, the motor body 200, which is already filled with liquid (such as cooling oil), is first fixedly connected to the connecting assembly 100 via a trolley. Then, the drive assembly 300 is started to drive the rotating shaft 12 to rotate, thereby driving the connecting assembly 100 and the motor body 200 to rotate. During the rotation, the liquid gradually flows out from inside the motor body 200, thus completing the entire airtightness test.

[0029] This application detachably assembles the motor body 200 onto the connecting assembly 100, and then drives the connecting assembly 100 to rotate via the drive assembly 300. During the rotation of the motor body 200, the liquid inside the motor body 200 is gradually discharged, thereby avoiding the inefficiency and safety hazards caused by using a crane and manual labor to flip the motor body 200, and greatly improving the efficiency of motor testing for enterprises.

[0030] Furthermore, based on the above embodiments, such as Figure 2 As shown, the connecting assembly 100 includes a first connecting plate 110, which is perpendicular to the rotating shaft 12. A second connecting plate 120 is provided on the side of the first connecting plate 110 away from the rotating shaft 12. A detachable first snap-fit ​​plate 130 and a second snap-fit ​​plate 140 are provided on one side of the second connecting plate 120. The first snap-fit ​​plate 130 and the second snap-fit ​​plate 140 are respectively provided with a first U-shaped groove 131 and a second U-shaped groove 141, which are used to form detachable connections with the motor body 200. In the working state, the motor body 200, which is filled with liquid inside, is first connected to the first U-shaped groove 131 or the second U-shaped groove 141 by using a crane, thereby fixing the motor body 200 to the connecting assembly 100.

[0031] Furthermore, based on the above embodiments, such as Figure 3 As shown, the drive assembly 300 includes a rotary motor 310 and a reducer 320 that are interconnected. The rotating shaft 12 is connected to the drive end of the reducer 320. When the rotary motor 310 is started, the reducer 320 reduces the rotational speed of the rotary motor 310 before driving the rotating shaft 12 to rotate. This allows the connecting assembly 100 to rotate at a stable speed around the rotating shaft 12, thereby driving the motor body 200 to rotate. This prevents the liquid inside the motor body 200 from splashing due to excessive rotational speed.

[0032] Furthermore, based on the above embodiments, such as Figure 2 As shown, a receiving groove 13 is provided at the bottom of the bracket 10. When the motor body 200 is rotating, its liquid gradually flows out from inside the motor body 200 onto the receiving groove 13, thereby avoiding direct discharge onto the ground and causing pollution.

[0033] Furthermore, based on the above embodiments, such as Figure 4As shown, the motor body 200 includes a housing 210. A liquid outlet 220 is provided at one end of the housing 210. A first connecting ring 230 and a second connecting ring 240 are provided on the outer wall of the housing 210. The second connecting ring 240 is located in the middle of the housing 210. The first connecting ring 230 is located between the liquid outlet 220 and the second connecting ring 240. When the volume of the liquid inside the motor body 200 is greater than half of the overall volume of the motor body 200, the second connecting ring 240 is connected to the second U-shaped groove 141. When the volume of the liquid inside the motor body 200 is less than half of the overall volume of the motor body 200, the first connecting ring 230 is connected to the first U-shaped groove 131. In this field, the airtightness test of the liquid inside the motor is divided into two types. One type involves filling the motor body with liquid, which is mainly used to test whether there is any leakage in the motor body under static conditions. The other type involves injecting liquid into the motor body to about one-third of its total volume, then starting the motor body 200 and testing whether there is any leakage under its working state. After the static test, due to the large volume and weight of the liquid inside, the second connecting ring 240 is located in the middle of the housing 210. Therefore, the housing 210 can be subjected to more even force through the connection between the second connecting ring 240 and the second U-shaped groove 141, thereby preventing the housing 210 from falling off or deforming during the rotation of the motor body 200. After the dynamic test, due to the smaller volume of the liquid inside, the first connecting ring 230 is located closer to the outlet 220 than the second connecting ring 240. Therefore, during the rotation of the motor body 200, the force on the housing 210 can be disregarded, and the outlet 220 can be deflected more quickly, allowing the internal liquid to flow out better.

[0034] Furthermore, based on the above embodiments, combined with Figure 2 and Figure 4 As shown, a plurality of first through holes 231 are provided on the first connecting ring 230 at preset intervals, and a plurality of second through holes 132 are provided on the edge of the first U-shaped groove 131. When the first connecting ring 230 contacts the first U-shaped groove 131, the first through holes 231 are aligned with the second through holes 132, and then the screw is turned, the motor body 200 and the first snap-fit ​​plate 130 can be connected.

[0035] Furthermore, based on the above embodiments, combined with Figure 2 and Figure 4As shown, a plurality of third through holes 241 are provided on the second connecting ring 240 at preset intervals, and a plurality of fourth through holes 142 are provided on the edge of the second U-shaped groove 141. When the second connecting ring 240 contacts the second U-shaped groove 141, the third through holes 241 are aligned with the fourth through holes 142, and then the screw is turned, the motor body 200 and the second snap-fit ​​plate 140 can be connected.

[0036] Furthermore, based on the above embodiments, such as Figure 4 As shown, the end faces of the liquid outlet 220 are parallel to those of the first connecting ring 230 and the second connecting ring 240. This allows for liquid discharge with a smaller deflection angle compared to placing the liquid outlet 220 at the top or bottom of the housing 210.

[0037] Furthermore, based on the above embodiments, such as Figure 3 As shown, a control console 14 is provided on the top of the bracket 10, and the control console 14 is electrically connected to the rotary motor 310 and the reducer 320. The control console 14 is used to control the start, stop and speed of the rotary motor 310 and the reducer 320.

[0038] The details of the exemplary embodiments described above are provided, and the invention can be implemented in other specific forms without departing from the spirit or essential characteristics of the invention. Therefore, the embodiments should be considered exemplary and non-limiting in all respects, and the scope of the invention is defined by the appended claims rather than the foregoing description. Thus, all variations falling within the meaning and scope of equivalents of the claims are intended to be included within the invention.
