Technical Field

[0002] High-precision parts refer to components that follow strict dimensional tolerances and quality standards during the manufacturing process. They are widely used in aerospace, medical equipment, automobile manufacturing, electronic communications and other fields.

In addition, during the cleaning process, sewage continuously seeps out from the leakage hole, so that the placement frame can achieve the dual effects of cleaning and drying. At the same time, through the design of the pickup port on the cleaning box and the use of the swing frame, the placement frame is rotated toward the pickup port at a certain angle after the cleaning operation is completed, so as to facilitate the collection of the cleaned hardware accessories. However, in actual use, since high-precision components are directly placed in the placement frame, the high-precision components will accumulate in the placement frame, and the positions where the high-precision components contact each other and are located at the bottom of the placement frame cannot directly contact the sprayed cleaning liquid, which leads to poor cleaning effect.

[0012] As a preferred technical solution of the present invention, the top end of the air supply pipe is fixedly connected to the rear end of the fixed pipe 2, and a pressure relief valve is fixedly installed at the rear end of the air supply pipe.

[0013] A cleaning method for a high-precision parts cleaning and decontamination device comprises the following steps: Add cleaning liquid into the water tank through the round hole at the top of the water tank cavity, then open the front end of the protective top cover upward to allow the placement frame to leak out, then place the high-precision parts to be cleaned on the placement net, and close the protective top cover; The driving motor is started, and the driving motor drives the driving shaft to rotate. The rotation of the driving shaft drives the rotating shaft to rotate through the belt transmission assembly, and then drives the eccentric shaft to rotate periodically around the axis of the rotating shaft, and then drives the moving plate to move back and forth periodically through the connecting rod, and the cleaning liquid in the water tank is pumped into the fixed box, and then transported to the nozzle through the one-way hose, so that the nozzle sprays high-pressure cleaning liquid to the high-precision parts; The rotation of the driving shaft will also drive the placement net to rotate through the placement frame. When the placement net rotates, the roller is driven to roll on the guide frame through the push rod assembly. When the roller contacts the inclined surface of the guide block, it will first drive the push rod assembly and the connecting block to move upward as a whole. When the connecting block reaches the top of the inner cavity of the limit groove, the push rod assembly cannot move upward and at the same time, the roller is still on the inclined surface of the guide block. As the placement net drives the roller to continue to rotate, the roller will continue to move up along the inclined surface. At this time, the spring 1 is compressed, and the lifting shaft slides upward in the inner cavity of the fixed tube 1, squeezing the air in the inner cavity of the fixed tube 1 into the rotating In the box, when the roller leaves the inclined plane, the placement net will fall down under the action of gravity, so that the placement net will be reset. At the same time, the elasticity of spring 1 will drive the lifting shaft to move downward in fixed tube 1, and the outside air will be drawn into fixed tube 1 through one-way air inlet pipe 1. As the placement net continues to rotate, the placement net continues to move up and down, thereby vibrating the high-precision parts on the placement net. When the high-precision parts vibrate, the position of the high-precision parts can be changed, so that the originally fitted parts are separated, and the surface originally located at the bottom is changed to the upper side, thereby performing all-round cleaning; While the placement net drives the push rod assembly to rotate continuously, air is continuously taken in into the rotating box, and then the air is transported to the air supply pipe through the connecting pipe and enters the fixed pipe 2. The air entering the fixed pipe 2 first pushes the moving shaft forward, and then drives the moving rod pipe to move forward continuously. When the front end of the moving rod pipe leaves the square groove area, the cleaning liquid in the water tank cannot enter the switching pipe. At this time, the moving rod pipe is connected to the one-way air intake pipe 2, and the moving plate draws the outside air into the moving plate and transports it to the spray assembly to dry the high-precision parts after cleaning. As the pressure in the air supply pipe continues to increase, when the opening pressure of the pressure relief valve is reached, the pressure is released through the pressure relief valve.

[0014] Compared with the prior art, the present invention has the following beneficial effects: The present invention provides a placement net that can move up and down in the placement frame. When the placement frame drives the placement net to rotate, the contact between the roller and the inclined surface of the guide frame can realize the placement net being driven to move up and down to vibrate the high-precision parts on the placement net, thereby causing the high-precision parts to change their position on the placement net, so that each surface of the high-precision parts can fully contact the cleaning liquid, thereby improving the cleaning effect. Moreover, the rotation of the push rod assembly can adjust the air intake in the assembly, so that the air in the air supply pipe continuously pushes the switching pipe forward, thereby realizing that after cleaning is completed, the front end of the switching pipe leaves the square groove, realizes automatic connection with the one-way air supply pipe 2, delivers air to the spray assembly, and realizes automatic drying of the high-precision parts.

A driving shaft 23 is fixedly sleeved at the output end of the driving motor 21, and a placement frame 22 is fixedly mounted at the top end of the driving shaft 23. The vibration assembly 3 includes a placement net 31, which is placed in the placement frame 22. A connecting block 32 is fixedly installed on the side wall of the placement net 31, a push rod assembly 33 is fixedly installed on the bottom end of the connecting block 32, and a roller 34 is rotatably connected to the bottom end of the push rod assembly 33. A guide frame 35 is fixedly installed on the side wall of the inner cavity of the cleaning box 1, and a limiting groove 36 is provided on the side wall of the placement frame 22. The push rod assembly 33 includes a fixed tube 331, which is fixedly mounted on the bottom end of the connecting block 32. The inner cavity of the fixed tube 331 is movably connected with a lifting shaft 332. The roller 34 is mounted on the bottom end of the lifting shaft 332. The surfaces of the fixed tube 331 and the lifting shaft 332 are sleeved with a spring 333. The two ends of the spring 333 are fixedly connected with the fixed tube 331 and the lifting shaft 332 respectively. The guide frame 35 includes a support ring 351 and a guide block 352. The guide block 352 is fixedly mounted on the top of the support ring 351. The roller 34 is placed on the top surface of the support ring 351. The connecting block 32 is movably connected in the limiting groove 36. The height of the limiting groove 36 is smaller than the height of the guide block 352. The end of the guide block 352 close to the roller 34 is an inclined surface. The driving assembly 2 also includes a belt transmission assembly 24 and an isolation deflector 25. The driving shaft 23 is connected to the rotating shaft 4 through the belt transmission assembly 24. The rotating shaft 4 is rotatably connected to the bottom end of the water tank 10. The isolation deflector 25 is a hollow cone. The driving shaft 23 is rotatably connected to the top of the isolation deflector 25. The driving motor 21 is located in the inner cavity of the isolation deflector 25. The two ends of the return water pump 5 are fixedly mounted on the bottom ends of the cleaning tank 1 and the water tank 10, respectively, and the return water pump 5 is connected to the cleaning tank 1 and the water tank 10; The spray assembly 7 includes a protective top cover 73, which is hinged at the top of the cleaning box 1, a nozzle 72 is fixedly installed at the top of the inner cavity of the protective top cover 73, a one-way hose 71 is fixedly installed in the middle of the nozzle 72, and the bottom end of the one-way hose 71 is installed in the inner cavity of the water tank 10; The regulating assembly 8 is located inside the water tank 10 .

[0019] The working principle and beneficial effects of the above technical solution are: The driving motor 21 drives the driving shaft 23 to rotate, and the rotation of the driving shaft 23 drives the placement frame 22 to rotate, thereby driving the placement net 31 in the placement frame 22 to rotate, and the push rod assembly 33 drives the roller 34 to move on the guide frame 35. Since the spring 1 333 has a certain elasticity, it will always provide a downward pressure to the lifting shaft 332. Then, when the roller 34 first contacts the inclined surface of the guide block 352, the roller 34 drives the push rod assembly 33 to push up as a whole. At this time, the elasticity of the spring 1 333 cannot be overcome, and the lifting shaft 332 will not move on the fixed tube 1 35. The lifting shaft 332 is pushed upward by the roller 34 to overcome the elastic force of the spring 333, thereby pushing the lifting shaft 332 upward in the fixed tube 331, pushing the outside air into the adjustment component 8, and when the roller 34 leaves the guide block 352, the placement net 31 will fall under the action of gravity, and at the same time When the air is removed from the placing net 31, the elastic force of the spring 333 pushes the lifting shaft 332 downward, and the outside air is sucked into the fixed tube 331. By setting up multiple sets of guide blocks 352, the placement net 31 can be moved up and down regularly and quickly, and the high-precision parts on the placement net 31 can be vibrated, thereby changing the position of the high-precision parts on the placement net 31, so that the parts that originally contacted each other are separated, and the parts that originally contacted the placement net 31 are separated from the placement net 31, so that the high-precision parts can be fully contacted with the cleaning liquid sprayed by the spray assembly 7 for cleaning, thereby improving the cleaning efficiency. In order to achieve a cleaning effect, when the driving shaft 23 rotates, the belt transmission component 24 drives the rotating shaft 4 to accelerate the rotation, and then drives the fluid conveying component 6 to send the cleaning liquid in the water tank 10 into the one-way hose 71, and then spray it on the high-precision parts located in the placement net 31 through the nozzle 72, so as to clean and remove dirt from the high-precision parts, and the cleaning liquid will directly fall on the isolation guide cover 25 through the placement net 31 and the placement frame 22, and flow to the bottom of the inner cavity of the cleaning box 1 through the guide of the isolation guide cover 25, and then be sent back into the water tank 10 through the return pump 5 to realize circulation.

[0020] Embodiment 2, as Figures 2 to 9 As shown, a rotating box 81 is fixedly installed on the top of the driving shaft 23, and a positioning plate 82 is rotatably connected to the bottom of the rotating box 81. A one-way hose 83 is fixedly installed on the side wall of the rotating box 81. The one-way hose 83 is communicated with the top of the fixed pipe 331. A one-way air inlet pipe 86 is fixedly installed at one end of the top of the fixed pipe 331 away from the one-way hose 83. A connecting pipe 84 is fixedly installed on the bottom end of the positioning plate 82. An air supply pipe 85 is fixedly installed on the bottom end of the connecting pipe 84. The air supply pipe 85 is fixedly installed in the water tank 10. The inner cavity of the water tank 10 is fixedly installed with a fluid delivery assembly 6, which includes a fixed box 61. The front end of the one-way hose 71 is fixedly connected to the fixed box 61. The inner cavity of the fixed box 61 is movably connected with a moving plate 62. The end of the moving plate 62 close to the rotating shaft 4 is rotatably connected to a connecting rod 63. The end of the connecting rod 63 away from the moving plate 62 is rotatably connected to an eccentric shaft 64. The eccentric shaft 64 is fixedly connected to the rotating shaft 4. A switching assembly 9 is fixedly installed on the front side of the fixed box 61. The switching assembly 9 includes a second fixed pipe 91, a switching pipe 93, a second one-way air inlet pipe 94 and a second spring 95. The second fixed pipe 91 and the switching pipe 93 are both fixedly connected to the fixed box 61. The second fixed pipe 91 is located on a side of the switching pipe 93 close to the cleaning box 1. The inner cavity of the second fixed pipe 91 is movably connected with a moving shaft 92. The second one-way air inlet pipe 94 is fixedly installed at the front end of the inner wall of the water tank 10. The switch tube 93 includes a bellows 931 and a moving rod tube 932, the bellows 931 and the moving rod tube 932 are fixedly connected, the moving rod tube 932 is inserted into the one-way air inlet pipe 94, the bellows 931 is fixedly connected to the fixed box 61, the moving shaft 92 is fixedly connected to the bellows 931, the two ends of the spring 95 are respectively fixedly connected to the fixed box 61 and the moving shaft 92, and a square groove is provided at the rear end of the one-way air inlet pipe 94; The top of the air supply pipe 85 is fixedly connected to the rear end of the fixed pipe 91, and a pressure relief valve is fixedly installed at the rear end of the air supply pipe 85; The working principle and beneficial effects of the above technical solution are: When the rotating shaft 4 rotates, it can drive the eccentric shaft 64 to rotate around the axis of the rotating shaft 4, and then drive the movable plate 62 to continuously move back and forth in the fixed box 61 through the connecting rod 63, so that the cleaning liquid in the water tank 10 is pumped into the fixed box 61, and then sent out through the one-way hose 1 71. When the driving shaft 23 rotates, the rotating box 81 will also rotate with the driving shaft 23 to ensure the stability of the connection between the one-way hose 2 83 and the rotating box 81, and the positioning plate 82 will not rotate to ensure that the position of the connecting pipe 84 will not change, so as to avoid the connecting pipe 84 from breaking, and the air entering the regulating component 8 will be The pressure in the rotating box 81 increases, which increases the pressure of the air sent into the air supply pipe 85, thereby driving the moving shaft 92 to move forward in the fixed pipe 91, pushing the moving rod pipe 932 forward, and stretching the bellows 931 to ensure the stability of the connection between the moving rod pipe 932 and the fixed box 61. Therefore, when cleaning high-precision parts, the moving rod pipe 932 is continuously moved forward. When the cleaning is completed, the front end of the moving rod pipe 932 is located at the front side of the square groove on the one-way air inlet pipe 94, thereby connecting the one-way air inlet pipe 94 and isolating the cleaning liquid in the water tank 10. At this time, the fluid drawn into the fixed box 61 The cleaning liquid is automatically switched to the air entering through the one-way air inlet pipe 94, so that the nozzle 72 sprays high-pressure air to dry the high-precision parts after cleaning. During the drying process, the front end of the moving rod pipe 932 is always located in front of the square groove opened on the one-way air inlet pipe 94, and in the drying process, since the pressure in the inner cavity of the air supply pipe 85 will continue to increase, a pressure relief valve will be provided at the rear end of the air supply pipe 85 to avoid the safety hazard caused by excessive pressure in the air supply pipe 85. After the drying is completed, the drive shaft 23 is stopped, and the pressure relief rod 96 is pulled forward with force, and the right side of the cleaning box 1 is connected to the A damping ring is provided at the contact position of the pressure relief rod 96. The damping ring can prevent the pressure relief rod 96 from falling off accidentally, so that the rear end of the pressure relief rod 96 leaves the air supply pipe 85, and the pressure in the air supply pipe 85 is released. At this time, the stretched spring 95 pulls the moving rod tube 932 and the moving shaft 92 back to their original positions under the action of elasticity, and at the same time, the bellows 931 contracts, so that the protective top cover 73 is opened and the high-precision components that have been blown dry are taken out. The fluid delivery component 6 is used to deliver cleaning liquid and air, so that the switching delivery of liquid and gas can be realized, which cannot be achieved by using a separate air pump or water pump.

[0021] Embodiment three, as Figures 1 to 9 As shown, the cleaning method of the high-precision parts cleaning and decontamination device comprises the following steps: Add cleaning liquid into the water tank 10 through the circular hole at the top of the inner cavity of the water tank 10, then open the front end of the protective top cover 73 upward to allow the placement frame 22 to leak out, then place the high-precision parts to be cleaned on the placement net 31, and close the protective top cover 73; The driving motor 21 is started, and the driving motor 21 drives the driving shaft 23 to rotate. The rotation of the driving shaft 23 drives the rotating shaft 4 to rotate through the belt transmission assembly 24, and then drives the eccentric shaft 64 to rotate periodically around the axis of the rotating shaft 4, and then drives the moving plate 62 to move back and forth periodically through the connecting rod 63, so that the cleaning liquid in the water tank 10 is pumped into the fixed box 61, and then transported to the nozzle 72 through the one-way hose 71, so that the nozzle 72 sprays the high-pressure cleaning liquid to the high-precision parts; The rotation of the drive shaft 23 will also drive the placement net 31 to rotate through the placement frame 22. When the placement net 31 rotates, the roller 34 is driven to roll on the guide frame 35 through the push rod assembly 33. When the roller 34 contacts the inclined surface of the guide block 352, it will first drive the push rod assembly 33 and the connecting block 32 to move upward as a whole. When the connecting block 32 reaches the top of the inner cavity of the limiting groove 36, the push rod assembly 33 cannot move further upward and at the same time, the roller 34 is still located on the inclined surface of the guide block 352. As the placement net 31 drives the roller 34 to continue to rotate, the roller 34 will continue to move up along the inclined surface. At this time, the spring 1 333 is compressed, and the lifting shaft 332 slides upward in the inner cavity of the fixed tube 1 331, The air in the inner cavity of 331 is squeezed into the rotating box 81. When the roller 34 leaves the inclined plane, the placement net 31 will fall downward under the action of gravity, so that the placement net 31 is reset. At the same time, the elasticity of the spring 333 will drive the lifting shaft 332 to move downward in the fixed tube 331, and the external air is drawn into the fixed tube 331 through the one-way air inlet pipe 86. As the placement net 31 continues to rotate, the placement net 31 continues to move up and down, thereby vibrating the high-precision parts on the placement net 31. When the high-precision parts vibrate, the position of the high-precision parts can be changed, so that the originally fitted parts are separated, and the surface originally located at the bottom is changed to the upper side, thereby performing all-round cleaning; While the placement net 31 drives the push rod assembly 33 to rotate continuously, air is continuously taken in into the rotating box 81, and then the air is transported to the air supply pipe 85 through the connecting pipe 84 and enters the fixed pipe 91. The air entering the fixed pipe 91 first pushes the movable shaft 92 forward, and then drives the movable rod pipe 932 to move forward continuously. When the front end of the movable rod pipe 932 leaves the square groove area, the cleaning liquid in the water tank 10 cannot enter the switching pipe 93. At this time, the movable rod pipe 932 is connected to the one-way air intake pipe 94, and the movable plate 62 draws the outside air into the movable plate 62 and transports it to the spray assembly 7 to dry the high-precision parts after cleaning. As the pressure in the air supply pipe 85 continues to increase, when the opening pressure of the pressure relief valve is reached, the pressure is relieved through the pressure relief valve.

[0022] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.

9. The cleaning method applicable to the high-precision parts cleaning and decontamination device according to claim 8 is characterized in that: The steps include: Add cleaning liquid into the water tank (10) through the circular hole at the top of the inner cavity of the water tank (10), then open the front end of the protective top cover (73) upward to allow the placement frame (22) to leak out, then place the high-precision parts to be cleaned on the placement net (31), and close the protective top cover (73); The driving motor (21) is started, and the driving motor (21) drives the driving shaft (23) to rotate. The rotation of the driving shaft (23) drives the rotating shaft (4) to rotate through the belt transmission assembly (24), thereby driving the eccentric shaft (64) to rotate periodically around the axis of the rotating shaft (4), and then driving the moving plate (62) to move forward and backward periodically through the connecting rod (63), so that the cleaning liquid in the water tank (10) is drawn into the fixed box (61), and then transported to the nozzle (72) through the one-way hose (71), so that the nozzle (72) sprays the high-pressure cleaning liquid toward the high-precision parts; The rotation of the drive shaft (23) also drives the placement net (31) to rotate through the placement frame (22). When the placement net (31) rotates, the roller (34) is driven to roll on the guide frame (35) through the push rod assembly (33). When the roller (34) contacts the inclined surface of the guide block (352), the push rod assembly (33) and the connecting block (32) are first driven to move upward as a whole. When the connecting block (32) reaches the top of the inner cavity of the limiting groove (36), the push rod assembly (33) cannot move upward further and at the same time, the roller (34) is still located on the inclined surface of the guide block (352). As the placement net (31) drives the roller (34) to continue to rotate, the roller (34) continues to move upward along the inclined surface. At this time, the spring 1 (333) is compressed, and the lifting shaft (332) moves upward in the inner cavity of the fixed tube 1 (331). The roller (34) moves upward to squeeze the air in the inner cavity of the fixed tube (331) into the rotating box (81). When the roller (34) leaves the inclined surface, the placement net (31) falls downward under the action of gravity, causing the placement net (31) to reset. At the same time, the elasticity of the spring (333) drives the lifting shaft (332) to move downward in the fixed tube (331), and draws the outside air into the fixed tube (331) through the one-way air inlet pipe (86). As the placement net (31) rotates continuously, the placement net (31) moves up and down continuously, thereby vibrating the high-precision parts located on the placement net (31). When the high-precision parts vibrate, the positions of the high-precision parts can be changed, so that the originally fitted parts are separated, and the surface originally located at the bottom is changed to the upper side, thereby performing all-round cleaning; While the placement net (31) drives the push rod assembly (33) to rotate continuously, air is continuously taken in the rotating box (81), and then the air is transported to the air supply pipe (85) through the connecting pipe (84), and then enters the fixed pipe (91). The air entering the fixed pipe (91) first pushes the moving shaft (92) forward, and then drives the moving rod pipe (932) to move forward continuously. When the front end of the moving rod pipe (932) leaves the square groove area, the cleaning liquid in the water tank (10) cannot enter the switching pipe (93). At this time, the moving rod pipe (932) is connected to the one-way air intake pipe (94), and the moving plate (62) draws the outside air into the moving plate (62) and transports it to the spraying assembly (7), so as to dry the high-precision parts after cleaning. As the pressure in the air supply pipe (85) continues to increase, when the opening pressure of the pressure relief valve is reached, the pressure is released through the pressure relief valve.
