[0048] 5. In the present invention, when the net basket is placed on the support plate from top to bottom, the net basket will press the pressing block downward due to the action of gravity, so that the pressing block moves downward. Since the diameter of the pressing block gradually increases from top to bottom, the diameter of the cross section of the contact position with the transmission rod will gradually decrease during the downward movement of the pressing block. Under the action of the elastic force of the second spring, the transmission rod will gradually drive the clamping plate to move in the direction close to the pressing block, thereby gradually clamping the net basket, thereby improving the stability of the net basket during rotation.

It should be noted that when the mesh basket 26 containing parts is placed on the support plate 16, in order to ensure the stability of the mesh basket 26 during the rotation process, the present solution is provided with a clamping plate 18 and a driving device, and each clamping plate 18 is driven by the driving device to move toward the mesh basket 26, thereby clamping the mesh basket 26 to improve the stability of the cleaning process.

[0078] like Fig. 9 As shown, in this embodiment, a baffle 21 is fixedly connected in the slide slot 25, the transmission rod 20 passes through the baffle 21, one end of the second spring 22 is connected to the baffle 21, and the other end is connected to the transmission rod 20. It should be noted that the baffle 21 is provided to support the second spring 22.

[0079] like Fig. 9As shown, in this embodiment, the clamping plate 18 is an L-shaped structure. It should be noted that the L-shaped clamping plate 18 is adapted to the corner of the basket 26 to further increase the clamping effect.

[0080] like Figure 7 As shown, in this embodiment, a sealing door 2 is slidably connected to the top of the spray box, a bracket 3 is provided on one side of the spray box, a cylinder 4 is provided on the bracket 3, and the output end of the cylinder 4 is connected to the sealing door 2.

[0081] like Figure 7 As shown, this embodiment is substantially the same as the above embodiment, except that a sealing door 2 is slidably connected to the top of the spray box, a bracket 3 is provided on one side of the spray box, a cylinder 4 is provided on the bracket 3, and the output end of the cylinder 4 is connected to the sealing door 2. It should be noted that the sealing door 2 is provided to seal the spray box to prevent the cleaning liquid from splashing outside the spray box when the spray box is working, and the cylinder 4 is provided to drive the sealing door 2 to open or close.

[0082] like Figure 7 As shown, in this embodiment, a slide rail 7 is provided on the top of the spray box, and a pulley 6 is provided at the bottom of the sealing door 2 to slide with the slide rail 7. It should be noted that the pulley 6 and the slide rail 7 are used to reduce the friction between the sealing door 2 and the spray box.

[0083] In this embodiment, a pressure sensor is provided at the bottom of the mounting groove 24, and the pressure sensor is electrically connected to the cylinder 4. It should be noted that the pressure sensor is used to sense the basket 26. When the basket 26 is placed on the support plate 16, the pressure block 19 contacts the pressure sensor, and the pressure sensor sends a sensing signal to the cylinder 4, which drives the sealing door 2 to move, thereby sealing the spray box.

[0084] The working principle of this embodiment is:

[0085] When it is necessary to spray the parts, the parts are placed in the basket 26, and then the basket 26 is placed on the support plate 16 from top to bottom. In the process of placing the basket 26 on the support plate 16 from top to bottom, the basket 26 will press the pressing block 19 downward due to gravity, so that the pressing block 19 moves downward. Since the diameter of the pressing block 19 gradually increases from top to bottom, the diameter of the cross section of the contact position between the pressing block 19 and the transmission rod 20 will gradually decrease during the downward movement of the pressing block 19, and the transmission rod 20 will gradually move under the elastic force of the second spring 22. The clamping plate 18 is driven to move toward the direction of the pressing block 19, thereby gradually clamping the net basket 26. After the net basket 26 is fixed, the sealing door 2 is closed, and the motor and the pressure pump 9 are started. The pressure pump 9 pressurizes the cleaning liquid in the water tank 8 and sprays it through the first nozzle 13 and the second nozzle 15 to act on the parts in the net basket 26 to remove the dirt on the parts. Secondly, while spraying, the motor drives the support plate 16 to rotate, so that the net basket 26 on the support plate 16 rotates, so that the cleaning liquid sprayed by the first nozzle 13 can spray various positions of the parts.
