[0002] In the motor manufacturing industry, the sealing test of the hub motor housing is a key step. The general test method is to seal the housing end first, then immerse it in water and pass gas to detect leakage. However, there is often residual moisture on the surface of the motor housing after the test, which requires cleaning and drying. The current process is to wipe it manually and then send the motor housing to the drying equipment. This process has the following shortcomings: Manual wiping is inefficient and costly, and traditional drying equipment is bulky and occupies a large space, making it difficult to efficiently meet the drying needs of large-scale motor casings, limiting production efficiency and cost control. Summary of the invention

[0005] It is further that: the driving assembly includes a left supporting seat, on which a driving shaft is rotatably mounted via a first bearing; one end of the driving shaft is fixedly connected to the left cover, and the other end of the driving shaft is connected to a motor.

[0006] The slewing support assembly comprises a right support seat, on which a support sleeve is fixed; the right cover is rotatably sleeved on the support sleeve via a second bearing; The heating assembly passes through the supporting sleeve and enters into the rotating drum.

[0007] The inner axial flow component comprises: An inner cylinder is coaxially arranged in the rotating cylinder; one end of the inner cylinder is fixedly connected to the right cover, and the other end of the inner cylinder is fixed with a gasket in contact with the left cover, and the circumference of the inner cylinder is provided with evenly distributed through grooves; A plurality of arc-shaped fan blades are fixed one by one to one side of the through slot and extend into the inner cylinder; Two annular sealing plates are respectively fixed on the inner walls at both ends of the inner cylinder, and the two ends of the arc-shaped fan blades are against the corresponding annular sealing plates; The heating component is arranged at the axial position in the inner cylinder, and a plurality of arc-shaped fan blades are arranged around the heating component; the inner side surface of the arc-shaped fan blade is bent toward the heating component, and an arc-shaped reflection plate is fixed on the inner side surface of the arc-shaped fan blade.

[0008] The outer circumferential surface of the inner cylinder is provided with a plurality of axial guide grooves evenly distributed around the axis of the inner cylinder; The inner wall of the drum is fixed with a plurality of axial guide plates evenly distributed around the axis of the drum, and the axial guide plates are correspondingly and slidably inserted in the axial guide grooves; There is a gap between the rotating drum and the inner drum, the interior of the inner drum is the inner cavity, and the space between adjacent axial guide plates is the outer cavity; the inner cavity is connected to the outer cavity through the through groove opened on the inner drum, and the outer cavity is connected to the outside of the rotating drum through the air outlet opened on the rotating drum.

[0009] The air inlet assembly on the right cover comprises: An annular sink groove is provided on the outer side of the right cover and is coaxial with the right cover; Multiple air inlets are opened in the annular sink and evenly distributed around the axis of the right cover; An annular filter screen is rotatably mounted in the annular sink; At least two pressing plates are fixed on the outer side of the right cover and press on the outer side of the annular filter; Among them, a plurality of cleaning cotton strips in contact with the outer side of the annular filter are fixed on one side of the pressure plate close to the annular filter; when the annular filter is rotated, the cleaning cotton strips clean the outer side of the annular filter.

[0010] The cleaning assembly comprises: A strip plate is fixed in the air outlet on the rotating drum; a row of blowing holes connected to the air outlet is formed on the strip plate, a clamping groove connected to the air outlet is formed at both sides of the blowing holes, and sliding grooves corresponding to the clamping grooves are formed on both sides of the strip plate; Two brush strips are inserted into the card slots on both sides one by one; Two pressure strips are slidably installed in the slide grooves on both sides in a one-to-one correspondence; The inner side of the pressure strip is pressed against one side of the brush strip, and the outer side of the pressure strip is provided with a fastening bolt which is threadedly connected to the strip plate, and the fastening bolt fastens the pressure strip toward the brush strip.

[0013] The design of the curved fan blades and curved reflective plates in the inner axial flow component enables most of the heat to be reflected and flow toward the through slots during the exhaust process, speeding up the transfer of heat to the outside; the gap between the inner and outer cylinders, combined with the through slots and air outlets, forms an air duct from the inside to the outside, ensuring that the hot air can flow smoothly through the cleaning component and blow toward the motor housing, thereby improving the drying effect.

[0014] The entire cleaning and drying device is divided into a drum part and an inner axial flow component part. The two parts can be plugged together for easy installation and disassembly, which not only simplifies maintenance work, but also improves the maintainability and flexibility of the equipment. The annular filter in the air intake component can filter out impurities and dust in the air to prevent them from entering the interior of the equipment. At the same time, the impurities on the filter surface can be easily cleaned through the cleaning cotton strips on the pressure plate, ensuring the cleanliness of the air intake and the stable operation of the equipment.

[0015] The brush bar in the cleaning assembly is positioned by a pressure strip and fastening bolts, making installation and disassembly easy; the wavy design of the slot makes the brush bar also wavy, which not only increases the contact area between the brush bar and the motor housing, but also improves the drying effect of the hot air on the brush bar, maintaining the water absorption performance of the brush bar.

A through hole is provided at the axis of the right cover 5, and a slewing support component 6 is installed in the through hole of the right cover 5, so that the right cover 5 and the inner axial flow component 8 can rotate together under the drive of the drum 1. The heating component 7 is arranged at the axis position in the drum 1, and one end of the heating component 7 passes through the slewing support component 6 to connect to an external power source or heat source. Figure 6 and Fig. 9 As shown, the entire cleaning and drying device is divided into a rotating drum 1 part and an inner axial flow component 8 part. These two parts can be plugged together to facilitate installation and disassembly to improve the maintenance efficiency of the inner axial flow component 8 part.

[0031] The left cover 3 and the right cover 5 are both equipped with an air inlet assembly 9 for supplying air to the inside of the drum 1, and an air outlet 11 opposite to the cleaning assembly 2 is opened on the side wall of the drum 1; While working; The driving component 4 is started, and the driving component 4 drives the left cover 3, the drum 1, the inner axial flow component 8 and the right cover 5 to rotate; the cleaning component 2 outside the drum 1 contacts the motor housing to clean and absorb the water stains on the motor housing; At the same time, the inner axial flow component 8 in the drum 1 draws air into the drum 1 through the air inlet component 9, and the air heated by the heating component 7 is exhausted to the outside of the drum 1 through the air outlet 11; the hot air blows through the cleaning component 2 outside the drum 1, keeping the cleaning component 2 dry, thereby improving the drying effect of the motor housing; Part of the hot air will also blow onto the motor housing to speed up the drying of the motor housing.

[0032] Combination Figure 5 and Figure 6As shown, the driving assembly 4 includes a left support seat 41, on which a driving shaft 42 is rotatably mounted via a first bearing 43. One end of the driving shaft 42 is fixedly connected to the center hole of the left cover 3, and the other end is connected to the motor.

The cooperation between the axial guide plates 12 and the axial guide grooves 812 also plays a role in transmitting torque, so that the rotating drum 1 can better drive the inner cylinder 81 to rotate.

[0036] After the inner cylinder 81 is inserted into the rotating drum 1, there is a gap between the rotating drum 1 and the inner cylinder 81. The inner cylinder 81 has an inner cavity 85, and the space between the adjacent axial guide plates 12 is an outer cavity 86. The inner cavity 85 is connected to the outer cavity 86 through the through groove 811 provided on the inner cylinder 81, and the outer cavity 86 is connected to the outside of the rotating drum 1 through the air outlet 11 provided on the rotating drum 1, forming an air duct from the inside to the outside.

[0039] Embodiment three: Based on the above embodiment 1, Figure 3 ,as well as Figures 5 to 8 As shown, a strip-shaped air outlet 11 is provided on the circumference of the drum 1 , and the cleaning assembly 2 is installed in the air outlet 11 .

[0040] The cleaning assembly 2 includes a strip plate 21 fixed in the air outlet 11, and a row of blowing holes 211 connected to the air outlet 11 are provided on the strip plate 21. A slot 212 connected to the air outlet 11 is provided on both sides of the blowing hole 211, and two brush strips 22 are correspondingly inserted into the slots 212 on both sides. The brush strips 22 are made of cotton material and have good water absorption effect. Slide grooves 213 corresponding to the slots 212 are provided on both sides of the strip plate 21, and two pressure strips 23 are correspondingly slidably installed in the slide grooves 213 on both sides; and the outer side of the pressure strip 23 is provided with a fastening bolt 24 connected to the strip plate 21 by threading. By tightening the fastening bolt 24 inward, the fastening bolt 24 will push the pressure strip 23 inward, so that the inner side of the pressure strip 23 presses the brush strip 22.

[0041] In this embodiment, the side of the card slot 212 close to the blowing hole 211 is wavy, and the compressed brush strip 22 will also be wavy; when working, the hot air blown out from the blowing hole 211 will blow through between the two brush strips 22, thereby improving the drying effect of the brush strips 22 and keeping the brush strips 22 always having a good water absorption effect.
