Description

Technical Field

[0001] The invention relates to the technical field of ultrasonic cleaning, in particular to a degreasing device for finishing treatment of a gearbox housing and an operating process thereof. Background Art

[0002] Ultrasonic cleaning uses the cavitation, acceleration and straight-forward flow effects of ultrasound in liquid to act on liquid dirt, so that the dirt layer is dispersed, emulsified and peeled off to achieve the cleaning purpose. The working principle of the ultrasonic cleaning machine is to convert the sound energy of the power ultrasonic frequency source into mechanical vibration through the transducer, and then radiate the ultrasound to the cleaning liquid in the tank through the wall of the cleaning tank. Under the action of ultrasound, the microbubbles in the liquid will keep vibrating. The cavitation effect is that ultrasound in the liquid will cause local pressure changes to form cavitation bubbles. When these bubbles suddenly close, they will generate a strong shock wave, which will directly impact the dirt layer, destroy the dirt and the adsorbed substances on the surface of the cleaning parts, and cause the dirt to fall off and disperse into the cleaning liquid.

[0003] During the ultrasonic cleaning and degreasing process of the gearbox housing, the gearbox housing has ravines on the surface, a complex structure and many internal pores. Ultrasonic cleaning may not be able to completely remove the internal stains. The energy of the ultrasonic wave is mainly transmitted through the surface.

After the arc plate frame 20 is moved, the unit spring 17 rebounds to reset the J-shaped column 18, and then the block 19 is inserted to block the channel of the Z-shaped tube 13. Therefore, the nozzle group 12 intermittently sprays fluid. The number of arc plate frames 20 installed on each split ring plate 21 is different, so the frequency of fluid spraying of a row of nozzle groups 12 is different. By installing different numbers of arc plate frames 20 on the split ring plate 21, the spraying frequency of the nozzle group 12 can be controlled and set.

[0038] refer to Figure 8 It is understood that the driving group 16 includes a cam frame 24 with one end fixed on the Z-shaped tube 13, a cam vertical shaft 25 and a cam horizontal shaft 26 supported on the cam frame 24, and a cam 23 fixed at one end of the cam vertical shaft 25, the other end of the cam vertical shaft 25 is meshed and connected to the bevel gear fixed at one end of the cam horizontal shaft 26 through a fixed bevel gear, the other end of the cam horizontal shaft 26 is meshed and connected to the outer gear ring 22 through a fixed shaft gear, and the cam vertical shaft 25 and the cam horizontal shaft 26 are respectively movably sleeved in two through holes opened on the cam frame 24.

[0040] refer to Fig.10It is understood that the tail moving part 27 includes a control disk 36 that is movably sleeved in a through hole opened in the middle of the bottom plate of the flow control barrel 31, a pressure column 35 that slides through the prismatic hole opened on the control disk 36, a hemispherical body 33 fixed at the end of the pressure column 35 outside the flow control barrel 31, a return compression spring 34 supported between the hemispherical body 33 and the control disk 36, and a plurality of C-shaped springs 37 evenly arranged around the control disk 36, one end of the C-shaped spring 37 is clamped with an arc groove evenly arranged on the outer wall of the control disk 36, and the other end of the C-shaped spring 37 is fixed to a protrusion set on the flow control barrel 31, the return compression spring 34 is sleeved on a short column fixed in the middle of the control disk 36, one end of the pressure column 35 is meshed and transmission-connected with a gear fixed on the swing control shaft 29 by setting a row of teeth, the outer wall of the cam 23 is in contact with the spherical surface of the hemispherical body 33, and one end of the inner frame 28 is fixed to the control disk 36.

The reason for the continuous swing of the jet cap 32 is that the split ring plate 21 rotates to drive the outer gear ring 22, and then the cam vertical shaft 25 is transmitted through the cam horizontal shaft 26. Next, the cam 23 continuously moves the hemisphere 33, and the hemisphere 33 reciprocates to drive the pressure column 35. Then the swing control shaft 29 reciprocates to drive the swing control frame 30, causing the jet cap 32 to swing reciprocatingly, and the fluid in the Z-tube 13 is injected into the flow control barrel 31, and then discharged through the jet cap 32. The fluid sprayed from the jet cap 32 is wavy, and the fluid can better guide the nearby bubbles to impact the deep hole slit of the gearbox housing. The adjustment group 10 includes a baffle plate 38 with one end fixed on the concave protective shell 4, a direction rod 39 vertically fixed at the other end of the baffle plate 38, a blocking spring 40 sleeved on the direction rod 39, and an adjustment frame 41 clamped between the blocking spring 40 and a row of unit springs 17.

[0042] The energy supplier 8 includes an energy supply round box 46 with one end fixedly connected to the bottom pipe 9, a fluid axis 47 arranged at the axis center of the energy supply round box 46, a plurality of fan blade assemblies 45 evenly arranged outside the fluid axis 47, a limiting ring body 44 clamped with all the fan blade assemblies 45, a limiting plate 43 vertically fixed on one side of the limiting ring body 44, and a worm 42 connected to a row of teeth meshing transmission on the limiting plate 43, the worm 42 is movably sleeved in a column hole opened on the bottom plate at one end of the energy supply round box 46, and a plate is also opened on the bottom plate of the energy supply round box 46 for the limiting plate 43 to slide through The hole is arranged at one end of the fluid shaft 47, and the other end of the fluid shaft 47 is sleeved in the through hole opened in the middle of the bottom plate at the other end of the energy supply round box 46, and the integrated long shaft 5 is connected to the fixed shaft gear at the end of the fluid shaft 47 through the fixed range increase gear 11, and the other end of the energy supply round box 46 is fixedly connected to the collecting and distributing pipe 7, and the worm 42 is connected to a row of teeth arranged at one end of the adjusting frame 41 through the fixed shaft gear, and a V-shaped frame 48 is fixed in the concave protective shell 4, and the integrated long shaft 5 is movably sleeved in the column hole opened in the V-shaped frame 48.

[0043] The fan blade assembly 45 includes a double-control frame 52 with one end fixed on the fluid shaft 47, a double-acting shaft 51 movably sleeved in a round hole opened on the double-control frame 52, an L-shaped frame 50 sliding through a square hole opened on the double-control frame 52, and a blade 49 fixed at one end of the double-acting shaft 51. One end of the L-shaped frame 50 is inserted into the annular groove opened on the inner wall of the limiting ring body 44, and the other end of the L-shaped frame 50 is meshed and connected with the cylindrical gear fixed on the double-acting shaft 51 by setting a row of teeth.

[0044] The integrated long shaft 5 is externally connected to the motor drive mechanism in the prior art. The integrated long shaft 5 rotates to drive the range-extending gear 11, and then the fluid shaft 47 rotates to drive the fan blade integration 45 to move in a circular motion, causing directional fluid transportation, that is, the cleaning fluid at the bottom of the square pool 1 is transported to the energy supply round box 46 through the bottom pipe 9, and then diffused to all the Z-shaped tubes 13 through the collecting and distributing pipe 7.

[0045] The intensity of the fluid conveyed in the energy supply round box 46 corresponds to the workload of the external drive motor of the integrated long shaft 5. In order to reduce the workload, only when more nozzle groups 12 spray fluid and more Z-tube 13 channels are opened, the fluid conveying in the energy supply round box 46 will be enhanced accordingly. The principle is that when more Z-tube 13 channels are opened, more unit springs 17 will apply elastic force to the adjustment frame 41, while the elastic force provided by the blocking spring 40 remains unchanged. Therefore, the adjustment frame 41 gradually moves closer to the blocking plate 38, and the adjustment frame 41 translates to drive the worm 42 to rotate, and then the limit plate 43 moves to drive the limit ring 44, and the limit ring 44 moves axially to drive all L-frames 50, and then the double-acting shaft 51 rotates to drive the blade 49. Compared with the fluid flow direction, the blade 49 becomes more inclined, so the blade 49 that revolves around at a constant speed pushes more fluid, and the fluid conveying in the energy supply round box 46 is enhanced, so that the fluid can meet the supply of more Z-tubes 13.
