[0034] Reference below Figure 1-Figure 4 A detection device 200 for a motor stator according to an embodiment of the present utility model is described.

[0035] like Figure 1-Figure 4 As shown, the detection device 200 of the motor stator according to the embodiment of the utility model includes: a frame 10, a detection bracket 20, a moving component 30 and a detection end 40.

[0036] A carrying platform 11 is arranged on the frame 10, and the carrying platform 11 is suitable for carrying the motor stator 100. The detection bracket 20 is arranged on the frame 10, and the moving component 30 is arranged on the detection bracket 20. The moving component 30 is provided with a moving bracket 31 movable in multiple directions. The detection end 40 is arranged on the moving bracket 31 and detects the depth of the heat sleeve of the motor stator 100 driven by the moving component 30.

[0037] It should be noted that the supporting platform 11 arranged on the frame 10 can carry the motor stator 100, which makes it convenient to place the motor stator 100 in the detection device 200. The detection bracket 20 is arranged on the frame 10 and the moving component 30 is arranged on the detection bracket 20, so that the moving component 30 can drive the moving bracket 31 to move in multiple directions, so that the detection end 40 located on the moving bracket 31 can move in multiple directions, so that the detection end 40 can detect the depth of the heat sleeve of the motor stator 100.

[0038] Among them, the detection end 40 can move in multiple directions, so that the detection end 40 can repeatedly detect the depth of the motor stator 100 heat sleeve at multiple positions of the motor stator 100, so that the detection result can be more accurate, thereby avoiding misjudgment caused by detection errors.

[0039] Therefore, the motor stator 100 to be inspected can be placed on the supporting platform 11 of the frame 10, and the movable component 30 located on the inspection bracket 20 can drive the movable bracket 31 to move in multiple directions so that the inspection end 40 located on the movable bracket 31 can move in multiple directions. In this way, the inspection end 40 can detect the depth of the heat sleeve of the motor stator 100 at multiple positions of the motor stator 100, thereby avoiding the influence of the inspection error on the judgment.

[0040] Furthermore, the detection end 40 is driven by the movable bracket 31 to detect the depth of the shrink sleeve of the motor stator 100, which does not require manual operation, thereby improving the detection efficiency.

[0041] According to the motor stator detection device 200 of the embodiment of the utility model, after the load platform 11 carries the motor stator 100, the movable component 30 on the detection bracket 20 can drive the movable bracket 31 to move in multiple directions, so that the detection end 40 can detect at multiple positions when detecting the depth of the heat-shrink sleeve of the motor stator 100, thereby making the error of the detection result lower. At the same time, the detection end 40 does not require manual intervention when detecting the depth of the heat-shrink sleeve of the motor stator 100, so the detection efficiency is higher.

[0042] In some embodiments, Figure 4 As shown, the moving component 30 includes: a first slide 32 , a first slider 321 , a second slide 33 , a second slider 331 , a third slide 34 and a third slider 341 .

[0043] The first slide 32 is arranged on the top of the detection bracket 20, the first slider 321 is arranged on the first slide 32, the first slider 321 slides along the first direction relative to the detection bracket 20, the second slide 33 is connected to the first slider 321, the second slider 331 is arranged on the second slide 33, the second slider 331 slides along the second direction relative to the detection bracket 20, the third slide 34 is connected to the second slider 331, the third slider 341 is arranged on the third slide 34, the movable bracket 31 is connected to the third slider 341, and the third slider 341 slides along the third direction relative to the detection bracket 20.

[0044] It should be noted that a slider is provided on the first slide 32, and the second slide 33 is connected to the first slider 321, so that when the first slider 321 slides in the first direction, it can drive the second slide 33 to slide in the first direction, and the second slide 33 is provided with a second slider 331, and the second slider 331 is connected to the third slide 34, so that when the second slider 331 slides along the second direction, it can drive the third slide 34 to slide in the second direction, and the third slide 34 is provided with a third slider 341, and the movable bracket 31 is connected to the third slider 341, so that when the third slider 341 slides in the third direction, it can drive the movable bracket 31 to slide in the third direction, and at the same time, the third slide 34 can slide in the second direction, and the second slide 33 can slide in the first direction, so that the movable bracket 31 can slide in the first direction, the second direction and the third direction, thereby ensuring that the movable bracket 31 can move in multiple directions, and further ensuring that the detection end 40 on the movable bracket 31 can detect the depth of the heat sleeve of the motor stator 100 at multiple positions of the motor stator 100.

[0045] Therefore, through the first slide 32, the second slide 33, the third slide 34 and the first slider 321, the second slider 331, and the third slider 341 arranged thereon, the movable bracket 31 can be moved in multiple directions, thereby driving the detection end 40 to move in multiple directions, so that the detection end 40 can detect the depth of the heat sleeve of the motor stator 100 at multiple positions of the motor stator 100, thereby avoiding detection errors.

[0046] In some embodiments, Figure 4 As shown, two first slides 32 are provided, and the two first slides 32 are arranged in parallel on the top of the detection bracket 20 , and the second slide 33 is connected to the two first sliding blocks 321 respectively.

[0047] It should be noted that the two first slides 32 are arranged in parallel on the top of the detection bracket 20, so that the second slide 33 is connected to the two first slides 321 respectively when connected to the first slider 321, so that the second slide 33 can slide more stably in the first direction, thereby making the movable bracket 31 more stable when moving, and thus not easily affecting the accuracy of the detection end 40.

[0048] Therefore, two first slides 32 are provided, so that the second slide 33 is more stable when connected to the first slider 321, so that the second slide 33 is not easy to shake when moving, thereby avoiding affecting the detection end 40, thereby ensuring the detection accuracy of the detection end 40.

[0049] In some embodiments, Figure 4 As shown, the moving component 30 further includes a first plate 35 , a second plate 36 and a reinforcing plate 37 .

[0050] The first plate 35 is connected to the second slider 331, the second plate 36 is connected to the edge of the first plate 35, and the second plate 36 is perpendicular to the first plate 35, the second plate 36 forms a connecting surface in the third direction, the connecting surface is connected to the third slide 34, the reinforcing plate 37 is vertically connected to the first plate 35, and the reinforcing plate 37 is also vertically connected to the second plate 36.

[0051] It should be noted that the first plate 35 is connected to the second slider 331, the second plate 36 is vertically connected to the first plate 35 and is located at the edge of the first plate 35, and a connecting surface is formed on the second plate 36, and the third slide 34 is connected to the connecting surface, so that the second slider 331 will not affect the movement of the third slider 341 on the third slide 34 when driving the third slide 34 to move along the second direction, thereby not affecting the movement of the movable bracket 31 in the third direction. At the same time, the connecting plate is vertically connected to the first plate 35 and the second plate 36, so that after the connecting plate is connected to the first plate 35 and the second plate 36, the connection strength between the first plate 35 and the second plate 36 can be improved, thereby ensuring the stability of the third slide 34.

[0052] Among them, after the first plate 35 and the second plate 36 are connected, they form an L-shaped plate. After the connecting plate is connected to the first plate 35 and the second plate 36, the connecting plate is located at the angle of the L-shaped plate, so that the structure of the L-shaped plate can be strengthened, thereby better fixing the third slide 34.

[0053] Thus, the third slide 34 is connected to the connecting surface formed on the second plate 36, and the second plate 36 is vertically connected to the first plate 35 and is located at the edge of the first plate 35, and the first plate 35 is connected to the second slider 331, so that the third slide 34 is connected to the second slider 331 through the second plate 36 and the first plate 35, so that the second slider 331 can drive the third slide 34 to move along the second direction, and at the same time, the connecting plate is vertically connected to the first plate 35 and the second plate 36, so that the connection stability of the first plate 35 and the second plate 36 can be improved, thereby improving the connection stability of the third slide 34.

[0054] In some embodiments, Figure 4 As shown, the movable bracket 31 includes: a first connecting plate 311 , a second connecting plate 312 and a fixing plate 313 .

[0055] The first connecting plate 311 is connected to the third slider 341 in the first direction, and the first connecting plate 311 extends along the third direction, one end of the second connecting plate 312 is connected to the edge of the first connecting plate 311 in the third direction, the fixed plate 313 is provided with a detection end 40, and the other end of the fixed plate 313 and the second connecting plate 312 are connected in the second direction.

[0056] It should be noted that the first connecting plate 311 is connected to the third slider 341, and the first connecting plate 311 extends along the third direction. At the same time, in the third direction, the edge of the first connecting plate 311 is connected to one end of the second connecting plate 312. At the same time, the other end of the second connecting plate 312 is connected to a fixed plate 313, and the fixed plate 313 is provided with a detection end 40. In this way, when the third slider 341 drives the first connecting plate 311 to move along the third direction, the first connecting plate 311 can drive the second connecting plate 312 and the fixed plate 313 to move along the third direction, so that the detection end 40 can move in the third direction.

[0057] Among them, the first connecting plate 311, the second connecting plate 312 and the fixed plate 313 are connected in sequence in the third direction, so that the movable bracket 31 can be formed into a straight plate, and the straight plate extends along the third direction, so that after the movable bracket 31 fixes the detection end 40, it can more conveniently drive the detection end 40 to move along the third direction.

[0058] Thus, the first connecting plate 311 , the second connecting plate 312 and the fixing plate 313 are sequentially connected in the third direction to form the movable bracket 31 , which makes it easier for the movable bracket 31 to drive the detection end 40 to move along the third direction.

[0059] In some embodiments, Figure 1-Figure 2 As shown, the detection bracket 20 includes: a first connecting frame 21 and a second connecting frame 22 .

[0060] A plurality of first connecting frames 21 are provided, and the plurality of first connecting frames 21 are respectively provided on the frame 10, and the plurality of first connecting frames 21 extend along the third direction, a plurality of second connecting frames 22 are provided, and the plurality of second connecting frames 22 are connected end to end to form a polygonal frame, and the polygonal frame surrounds an avoidance hole 23, and the movable component 30 is provided on the second connecting frame 22 and the movable bracket 31 extends into the avoidance hole 23 and drives the detection end 40 to move.

[0061] It should be noted that multiple first connecting frames 21 are arranged on the frame 10, and multiple first connecting members extend along the third direction, so that the first connecting frames 21 can provide installation fulcrums for the second connecting frames 22, and multiple second connecting frames 22 are connected end to end to form a polygonal frame, which will be connected to the first connecting bracket. In this way, the moving component 30 is arranged on the polygonal frame to detect the motor stator 100.

[0062] Among them, the polygonal frame encloses an avoidance hole 23, so that when the moving component 30 is set on the second connecting frame 22, the moving bracket 31 will extend into the avoidance hole 23, so that when the moving bracket 31 drives the detection end 40 to move in multiple directions, it is located within the range of the avoidance hole 23, so that the moving bracket 31 can have a detection range in the first direction and the second direction, so that the detection device 200 can better detect the motor stator 100.

[0063] Therefore, multiple first connecting frames 21 are arranged on the frame 10 to provide installation fulcrums for the second connecting frames 22, and multiple second connecting frames 22 can form a polygonal frame when connected end to end, and the polygonal frame surrounds an avoidance hole 23. In this way, after the moving component 30 is set on the second frame, the moving bracket 31 will extend into the avoidance hole 23, so that the range of movement of the moving bracket 31 in the first direction and the second direction is limited within the avoidance hole 23, so that the moving bracket 31 will not detach from the detection bracket 20.

[0064] In some embodiments, the support platform 11 can be slidably disposed on the frame 10, and the support platform 11 is suitable for sliding along a first direction relative to the frame 10. When the support platform 11 slides relative to the frame 10, there is a first position and a second position. The first position is that the support platform 11 is located at the edge of the frame 10, and the second position is that the support platform 11 is directly opposite to the detection bracket 20.

[0065] It should be noted that the support platform 11 can slide relative to the frame 10 in a first direction, so that the support platform 11 can move on the frame 10 after carrying the motor stator 100. At the same time, the support platform 11 has a first position and a second position. When the support platform 11 is located at the first position, the support platform 11 is located at the edge of the frame 10, so that the motor stator 100 can be more easily placed on the support platform 11, and when the support platform 11 is located at the second position, the support platform 11 is opposite to the detection bracket 20, so that the moving part 30 on the detection bracket 20 is at least partially opposite to the motor stator 100, so that the detection end 40 can detect the depth of the stator heat sleeve at multiple positions of the motor stator 100, thereby avoiding detection errors.

[0066] Among them, the frame 10 can be connected to the production line, so that when the support platform 11 is at the first position, the motor stator 100 produced on the production line can be transferred to the support platform 11 and moved to the second position for inspection, thereby improving the production efficiency of the motor stator 100.

[0067] Thus, the support platform 11 can slide relative to the frame 10, so that the motor stator 100 can be placed on the support platform 11 more easily, that is, when the support platform 11 is in the first position, the motor stator 100 can be placed on the support platform 11 more conveniently, and when the support platform 11 is in the second position, the support platform 11 is opposite to the detection bracket 20, so that the moving part 30 on the detection room can better drive the detection end 40 to detect the depth of the heat sleeve of the motor stator 100.

[0068] In some embodiments, the carrying platform 11 includes: a guide rail 111 and a carrying platform body 112 .

[0069] The guide rail 111 is arranged on the frame 10 and extends along the first direction. The support platform body 112 is provided with a guide rail 111 slider, and the guide rail 111 slider is slidably matched with the guide rail 111. The support platform body 112 is suitable for supporting the motor stator 100.

[0070] It should be noted that when the guide rail 111 is arranged on the frame 10, it will extend along the first direction, so that the support platform 11 can slide in the first direction relative to the frame 10 after the guide rail 111 slider slides with the guide rail 111, so that the support platform 11 can move to the edge of the frame 10, and the support platform body 112 can carry the motor stator 100, so that the support platform body 112 can drive the motor stator 100 to move along the first direction, thereby making the motor stator 100 more easily detected by the detection end 40.

[0071] Therefore, the support platform body 112 can support the motor stator 100, and at the same time, the support platform body 112 cooperates with the guide rail 111 on the frame 10 through the guide rail 111 slider, so as to achieve movement in the first direction relative to the frame 10, and then the support platform body 112 can drive the motor stator 100 to move in the first direction.

[0072] In some embodiments, at least one positioning member 113 is disposed on a side of the support platform body 112 facing the detection bracket 20 , and the positioning member 113 is suitable for positioning the motor stator 100 .

[0073] It should be noted that the positioning piece 113 can cooperate with the motor stator 100 to ensure that when the motor stator 100 is placed on the supporting platform body 112, the position of the motor stator 100 is fixed and the motor stator 100 can be heat-shrink-fitted toward the detection bracket 20, so that the detection end 40 can more easily detect the depth of the heat-shrink fitting of the motor stator 100.

[0074] The positioning member 113 may be configured as a positioning pin, which makes it easier for the motor stator 100 to cooperate with the positioning pin, so that the motor stator 100 can be placed on the carrier body 112 more quickly, thereby increasing the detection speed.

[0075] Therefore, by providing the positioning member 113 on the carrier body 112 , the position of the motor stator 100 can be fixed when placed on the carrier body 112 , so that it is more convenient for the detection end 40 to perform shrink fit detection on the motor stator 100 .

[0076] In some embodiments, a plurality of support members 114 are disposed on one side of the support platform body 112 facing the detection bracket 20 , and the support members 114 are suitable for supporting the motor stator 100 .

[0077] It should be noted that after the positioning member 113 of the motor stator 100 is positioned and placed on the supporting platform 11, the multiple support members 114 can support the motor stator 100, so that the motor stator 100 is not easy to shake when moving with the supporting platform body 112. At the same time, after supporting the motor stator 100, the multiple support members 114 can avoid direct contact between the motor stator 100 and the surface of the supporting platform body 112, which can protect the motor stator 100 and ensure that the motor stator 100 remains level on the side facing the detection bracket 20, thereby avoiding affecting the detection result.

[0078] The support member 114 is constructed as a support column and the heights of the multiple support columns are the same, so that the motor stator 100 can remain horizontal on the side facing the detection bracket 20 after being supported, thereby not affecting the detection result of the detection end 40.

[0079] Therefore, the motor stator 100 is supported by multiple support members 114, which prevents the motor stator 100 from directly contacting the surface of the support platform body 112, thereby protecting the motor stator 100, and also enables the motor stator 100 to remain horizontal on the side facing the detection bracket 20, thereby avoiding affecting the detection result.

[0080] In some embodiments, Figure 5-Figure 6 As shown, the detection end 40 is constructed as a laser displacement sensor, so that when detecting the depth of the heat-shrink sleeve of the motor stator 100, at least three points are selected on the end face of the motor stator 100 and the end face of the motor housing. In this embodiment, three points are selected, namely a, b, and c. The selected measuring points need to be evenly distributed on the circumference of the motor stator 100, and the connecting line between the measuring point of the motor stator 100 and the measuring point of the housing needs to pass through the product axis. The moving component 30 drives the laser displacement sensor to move to the measuring point, and measures the end face height dimensions La2, Lb2, Lc2 of the motor stator 100 and the end face dimensions La1, Lb1, Lc1 of the motor housing. In this way, the depth of the heat-shrink sleeve of the motor stator 100 is L=La2-La1, or L=Lb2-Lb1, or L=Lc2-Lc1. In this way, the calculated depth is compared with the set depth dimension range to judge the assembly quality of the motor.
