Description

Technical Field

[0001] This utility model belongs to the field of parts cleaning technology, and more specifically relates to a hollow shaft cleaning and drying device. Background Technology

[0002] Hollow shaft parts (such as vehicle drive shafts, valve sleeves, hydraulic cylinders, etc.) have many surface components and complex structures, thus requiring multiple machining processes. This results in a significant amount of residual lubricant, chips, oil, etc., on the surface, especially at corners and holes between components. If not thoroughly cleaned, this can affect subsequent assembly. Traditional cleaning methods typically involve workers repeatedly rinsing the inner and outer surfaces of the hollow shaft with a handheld spray gun or immersing the entire shaft in a cleaning tank for ultrasonic cleaning. However, manual rinsing is labor-intensive, inefficient, and produces poor cleaning results. Ultrasonic cleaning is time-consuming, energy-intensive, and requires considerable effort to dry the hollow shaft, making it inefficient as well. Utility Model Content

A clamping fixture 3 is provided between adjacent partitions 2. Several workstations are provided inside the cleaning hood, including loading and unloading workstations 4, several cleaning workstations, and several drying workstations. Each cleaning workstation is equipped with a cleaning device, and each drying workstation is equipped with a drying device. The cleaning devices include a fixed-point cleaning mechanism 5, a scanning cleaning mechanism 6, and a rinsing mechanism 7. The drying devices include a fixed-point drying mechanism 8 and a scanning drying mechanism 9.

[0019] like Figures 1 to 7 As shown, the rotating frame 1 rotates so that the loading and unloading station 4 is located at the opening of the cleaning hood. The worker positions and fixes the hollow shaft to be cleaned on the fixture 3. The rotating frame 1 rotates the hollow shaft through each cleaning station and drying station in sequence, and finally returns to the loading and unloading station 4. The worker removes the cleaned and dried hollow shaft and places the hollow shaft to be cleaned again, realizing a cycle of cleaning and drying with high efficiency.

[0020] Specifically, the fixed-point cleaning mechanism 5 can clean all corners on the outer surface of the hollow shaft, improving the cleaning effect. The scanning cleaning mechanism 6 can rinse the entire outer surface and inner hole of the hollow shaft to achieve overall cleaning. Then, the rinsing mechanism 7 rinses away the cleaning liquid on the surface and inner hole of the parts. Finally, the fixed-point drying mechanism 8 and the scanning drying mechanism 9 dry the inside and outside of the hollow shaft as well as the corners.

[0021] like Figure 1 and Figure 2 As shown, specifically, the bottom of the rotating frame 1 is connected to a servo drive motor, which causes the rotating frame 1 to rotate to each workstation at a certain angle each time.

[0022] like Figure 3 and Figure 4 As shown in the preferred embodiment, the fixed-point cleaning mechanism 5 includes a movable support 10 and a first support plate 11.

After the moving bracket 10 and the first support plate 11 are in place, the external cleaning fluid delivery mechanism delivers cleaning fluid to the gas-liquid circuit plate 12 and the first gas-liquid circuit block 15 respectively. Then, the cleaning fluid is sprayed onto the hollow shaft through the surface spray head 13, the point spray pipe 14, and the first vertical spray head 16. The surface spray head 13 forms a planar water flow that sprays onto the hollow shaft, the point spray pipe 14 forms a thin strip of water that sprays onto the hollow shaft, and the first vertical spray head 16 rinses the hollow shaft from above and cleans the inner hole, thereby achieving fixed-point cleaning of the hollow shaft.

[0024] Specifically, the movement of the movable support 10 and the lifting and lowering of the first support plate 11 are both driven by cylinders, and guide rods are provided to improve the stability of the movement.

[0025] like Figure 4 As shown, specifically, the point injection pipe 14 is provided with a number of injection holes, and the point injection pipe 14 has different shapes, such as straight pipe, T-shaped pipe, L-shaped pipe, etc.

[0028] like Figure 5 As shown, specifically, when the hollow shaft is located at the scanning and cleaning station, the first annular spray pipe 17 and the spray rod 18 are lowered by the lifting mechanism, while the external cleaning fluid delivery mechanism delivers cleaning fluid to it. The cleaning fluid is sprayed onto the outer surface of the hollow shaft through the first spray nozzle 19 on the first annular spray pipe 17, and the spray rod 18 extends into the hole of the hollow shaft to rinse the hole wall.

[0029] Specifically, the lifting and lowering of the first annular injection pipe 17 and the injection rod 18 are both driven by cylinders, and guide rods are provided to improve the stability of movement.

[0030] like Figure 6As shown, in this preferred embodiment, the rinsing mechanism 7 includes a second annular spray pipe 20 and a second support plate 21.

The second gas-liquid passage blocks 23 are provided with second vertical nozzles 24, and the second annular spray pipe 20 and the second gas-liquid passage blocks 23 are connected to an external clean water conveying mechanism.

[0031] like Figure 6 As shown, specifically, when the hollow shaft is in the rinsing station, the second annular spray pipe 20 and the second support plate 21 are lowered by the lifting mechanism, while the external clean water conveying mechanism conveys clean water to it. The second spray nozzle 22 on the second annular spray pipe 20 sprays clean water onto the outer surface of the hollow shaft, and the second vertical nozzle 24 on the second support plate 21 sprays clean water onto the outer surface and inner hole of the hollow shaft from above to rinse the hollow shaft.

[0032] like Figure 1 As shown in this example, the structure of the fixed-point drying mechanism 8 is the same as that of the fixed-point cleaning mechanism 5. Its gas-liquid circuit board 12 and the first gas-liquid circuit block 15 are both connected to the external high-pressure gas transmission mechanism. That is, the external high-pressure gas transmission mechanism transmits high-pressure air to the hollow shaft for fixed-point drying through the surface spray head 13 and the point spray pipe 14 on the gas-liquid circuit board 12 and the first vertical nozzle 16 on the first gas-liquid circuit block 15.

[0033] like Figure 1 As shown in the example, the structure of the scanning and drying mechanism 9 is the same as that of the scanning and cleaning mechanism 6. Its first annular jet pipe 17 and jet rod 18 are both connected to an external high-pressure air supply mechanism. That is, the external high-pressure air supply mechanism sends high-pressure air through the first annular jet pipe 17 and jet rod 18 to scan and dry the hollow shaft.

[0034] like Figure 7 As shown in the preferred embodiment, the fixture 3 includes a fixture plate 25 fixed on the frame.

[0035] like Figure 7 As shown, specifically, the hollow shaft is supported by the support rod 27 on the clamp plate 25, positioned by the locating pin 26, and fixed by the quick clamping mechanism 28.

[0036] like Figure 3As shown, specifically, during fixed-point cleaning, rinsing, and fixed-point drying, the first vertical nozzle 16 and the second vertical nozzle 24 are directly aligned with the top opening of the hollow shaft to clean and dry the inside of the hollow shaft. Additionally, the first vertical nozzle 16 and the second vertical nozzle 24 are aligned with the side spray pipe 29 on the clamp plate 25, and the side nozzle 30 on the side spray pipe 29 is used to rinse and dry the outer side of the hollow shaft.

[0037] In this example, preferably, the side of the partition 2 is provided with a rubber plate (not shown in the figure). The rubber plate contacts the inner wall of the cleaning hood and slides with the rotating frame 1 inside the cleaning hood, so that each station is independent of each other and avoids mutual interference between the stations during cleaning and drying.

[0038] like Figure 7 As shown, specifically, two clamping fixtures 3 are arranged between adjacent partitions 2, and the two clamping fixtures 3 are symmetrical in translation. The moving bracket 10 is provided with two spraying mechanisms corresponding to the clamping fixtures 3, so as to realize the one-time clamping and cleaning of two hollow shafts and improve the cleaning efficiency.
