Description

Technical Field

[0001] The present invention relates to the technical field of cleaners, and more specifically to a high-efficiency cleaner for the surface of automotive parts. Background Art

[0002] The wheel hub is not only a key metal component for supporting the tire, but also bears important functions during vehicle driving. The main components of the wheel hub include the rim, spoke, offset, wheel flange, and groove bottom. Before installing the wheel hub, it is necessary to clean its surface to ensure normal use in the later stage.

[0003] However, in actual use, we found that traditional wheel hub cleaning methods mostly use high-pressure water guns for rinsing. Although this method can quickly remove some dirt, the cleaning effect on stubborn stains inside the rim is limited. At the same time, the transportation of the wheel hub generally relies on staff for handling, which not only increases the workload of the staff, but also greatly reduces the cleaning efficiency. For this reason, we propose a high-efficiency cleaner for the surface of automotive parts. Summary of the Invention

[0039] Embodiment 1:

[0040] Please refer to Figure 1-11, the present invention provides a technical solution:

In the initial state, the telescopic pipes 22 are in a contracted state, and the scrapers 12 keep a certain distance from the hub. As the water flow in the cleaning pipe 11 drives through the fan blades 32 and the guide rods 33 on the mounting frame 31, the connecting pipe 21 and the telescopic pipes 22 start to rotate. During the rotation process, the telescopic pipes 22 gradually extend under the action of centrifugal force and water flow, pushing the scrapers 12 to approach the hub until the cleaning layer 34 on the scrapers 12 fits the inner side of the rim. Through the unfolding of the telescopic pipes 22, the cleaning pipe 11 can be exactly located at the center of the hub. At this time, the cleaning pipe 11 and the inner pipe 61 are exactly opposite to the hub center hole;

[0046] The rotating member 3 includes a mounting frame 31 arranged in the cleaning pipe 11, a fan blade 32 is rotatably arranged on the mounting frame 31, a guide rod 33 is arranged between the fan blade 32 and the connecting pipe 21.

[0048] The measuring part 5 includes a distance measuring instrument 51 arranged on the fixing rod 44. A receiving ring 52 for cooperating with the distance measuring instrument 51 is arranged on the cleaning pipe 11. The distance measuring instrument 51 and the receiving ring 52 are common existing structures. Among them, the distance measuring instrument 51 can use infrared technology for measurement. The receiving ring 52 is for the normal use of the distance measuring instrument 51. A controller 53 is arranged on the manipulator 10. The controller 53 is respectively connected to the distance measuring instrument 51, the first electric push rod 81, the control valve 43 and the control valve 62. At the same time, due to the rotation of the telescopic pipe 22, the distance measuring instrument 51 will rotate accordingly. Therefore, a storage battery is added to the fixing rod 44 for the distance measuring instrument 51 to supply power to it. At the same time, the connection method also adopts a wireless connection mode, such as Bluetooth connection. For the control valve 62, the wire harness can enter from the inside of the cleaning pipe 11, pass through the inside of the connecting pipe 21, and then pass out of the cleaning pipe 11 until it is connected to the control valve 62;

[0049] The ejecting part 6 includes an inner pipe 61 slidably arranged at one end of the cleaning pipe 11 away from the manipulator 10. A control valve 62 is arranged on the cleaning pipe 11. A sealing cover 63 is arranged outside the control valve 62. A fixing ring 64 is arranged inside the cleaning pipe 11. A first spring 65 is arranged between the inner pipe 61 and the fixing ring 64. A plurality of main shafts 66 are rotatably arranged on the outside of the end of the inner pipe 61 away from the manipulator 10. A compensation pipe 67 is arranged on each main shaft 66. The inner pipe 61 and the compensation pipe 67 are connected through a hose. A torsion spring 68 is arranged on the outside of each main shaft 66. Two ends of the torsion spring 68 are respectively connected to the compensation pipe 67 and the inner pipe 61;

[0050] The clamping plates 13 are respectively arranged on the outside of the wheel hub;

[0051] The synchronous clamping unit 7 is arranged on the support frame 1 and is used to cooperate with the measurement result of the fitting measurement unit 2 to clamp and position the wheel hub;

[0052] The synchronous clamping unit 7 includes two sliding frames 71 respectively arranged on the support frame 1. A displacement plate 72 is slidably arranged in each sliding frame 71. A displacement member 8 is arranged on the support frame 1 and is used in cooperation with the sliding frame 71 to adjust the distance between the two displacement plates 72 in cooperation with the distance measuring instrument 51 and the controller 53, so as to clamp different-sized hubs. Connecting members 9 are arranged on the displacement plates 72 and are used in cooperation with the adjacent clamping plates 13;

[0053] The displacement member 8 includes a first electric push rod 81 arranged on the support frame 1. A displacement frame 82 is arranged at the end of the first electric push rod 81. Deflection rods 83 are respectively rotatably arranged at both ends of the displacement frame 82, and the ends of the deflection rods 83 are respectively rotatably connected to the adjacent displacement plates 72;

[0054] The connecting member 9 includes a second spring 91 arranged between the displacement plate 72 and the clamping plate 13.

[0055] After starting, the manipulator 10 drives the cleaning pipe 11 and its attached components including the scraper 12, the fitting measurement unit 2, etc. close to the hub to be cleaned. In the initial state, the telescopic pipe 22 is in a contracted state, and the scraper 12 keeps a certain distance from the hub. As the water flow in the cleaning pipe 11 drives the fan blades 32 and the guide rods 33 on the mounting frame 31, the connecting pipe 21 and the telescopic pipe 22 start to rotate. During the rotation process, the telescopic pipe 22 gradually extends under the action of centrifugal force and water flow, pushing the scraper 12 closer to the hub until the cleaning layer 34 on the scraper 12 fits the inner side of the rim. Then, the distance measuring instrument 51 in the fitting measurement unit 2 starts to work, receives the reflected signal through the receiving ring 52, measures the size information of the hub, and transmits the data to the controller 53;

[0056] During the water supply process, the cleaning liquid in the cleaning liquid tank 42 is first transported to the cleaning pipe 11 through the built-in water pump, the control valve 43, and the hose, and then the inner and outer sides of the hub are flushed through the liquid outlet pipe 45 and the nozzle 46. The scraper 12 rotates with the cleaning pipe 11 in the fitting state, and the cleaning layer 34 on it effectively scrapes off the stains and dirt on the surface of the hub;

[0057] The controller 53 clamps and positions the hub through the synchronous clamping unit 7 according to the received size information. During the process, the first electric push rod 81 drives the displacement frame 82 to move, drives the displacement plate 72 to slide in the sliding frame 71 through the deflection rod 83, adjusts the distance between the two displacement plates 72 to adapt to different-sized hubs, and the spring on the displacement plate 72 cooperates with the clamping plate 13, and the clamping plate 13 is pressed against the outer side of the hub through the elastic force of the second spring 91 to achieve clamping and positioning;

[0058] After the clamping is completed, the control valve two 62 starts to work, opens the valve, enables the cleaning liquid to enter the inner pipe 61, and then can push the inner pipe 61 to move outward, and then pushes the inner pipe 61 along the hub center hole to the outside of the hub. Under the action of the torsion spring 68, the compensation pipe 67 quickly bounces open and flushes the outside of the hub. The setting of the spring one 65 ensures the subsequent reset of the inner pipe 61 and the compensation pipe 67;

[0059] During the entire cleaning process, the controller 53 monitors the working states of all components in real time and adjusts the cleaning liquid flow rate as needed to ensure the optimization of the cleaning effect. After the cleaning is completed, through the cooperation of the water pump inside the water tank and the control valve one 43, clean water begins to be injected into the cleaning pipe 11 to perform secondary cleaning on the hub;

[0060] After the cleaning is completed, the controller 53 issues an instruction to make the electric push rod one 81 move in the reverse direction, driving the displacement plate 72 and the clamping plate 13 to reset. At the same time, the water flow in the cleaning pipe 11 stops, and the scraper 12 and the ejecting member 6 also return to the initial positions. The manipulator 10 drives the cleaning pipe 11 and its attached components to reset as a whole, preparing for the next cleaning operation.

[0061] Embodiment 2:

[0062] Please refer to Figure 12-13 , the present invention provides a technical solution:

[0063] Different from Embodiment 1, this solution provides another implementation manner of the connecting member 9: the clamping plates 13 are each composed of two positioning plates 92 of the same size. The connecting member 9 includes a plurality of electric push rods two 93 respectively arranged between adjacent displacement plates 72 and positioning plates 92. The electric push rods two 93 are also remotely connected to the controller 53 via Bluetooth. The two groups of positioning plates 92 can be respectively controlled to clamp through the electric push rods two 93, so that the clamping positions can also be cleaned.

[0064] Refer to Figure 5-13 , after starting, the manipulator 10 drives the cleaning pipe 11 and its attached components including the scraper 12, the fitting type measuring unit 2, etc. to approach the hub to be cleaned. In the initial state, the telescopic pipe 22 is in a contracted state, and the scraper 12 keeps a certain distance from the hub. As the water flow in the cleaning pipe 11 is driven by the fan blades 32 and the guide rods 33 on the mounting frame 31, the connecting pipe 21 and the telescopic pipe 22 start to rotate. During the rotation process, the telescopic pipe 22 gradually elongates under the action of centrifugal force and water flow, pushing the scraper 12 towards the hub until the cleaning layer 34 on the scraper 12 fits the inner side of the rim. Then, the distance measuring instrument 51 in the fitting type measuring unit 2 starts to work, receives the reflected signal through the receiving ring 52, measures the size information of the hub, and transmits the data to the controller 53;

[0065] During the water supply process, the cleaning liquid in the cleaning liquid tank 42 is first transported to the cleaning pipe 11 through the built-in water pump, control valve 1 43, and hose, and then the inner and outer sides of the wheel hub are rinsed through the liquid outlet pipe 45 and the nozzle 46. The scraping plate 12 rotates with the cleaning pipe 11 in the fitting state, and the cleaning layer 34 thereon effectively scrapes off the stains and dirt on the surface of the wheel hub;

[0066] The controller 53 clamps and positions the wheel hub through the synchronous clamping unit 7 according to the received size information. During the process, the electric push rod 1 81 drives the displacement frame 82 to move, drives the displacement plate 72 to slide in the sliding frame 71 through the deflection rod 83, adjusts the distance between the two displacement plates 72 to adapt to wheel hubs of different sizes, and a set of electric push rods 2 93 facing each other on the displacement plate 72 start to work and drive the positioning plates 92 of this group to shift, completing the clamping and positioning work of the wheel hub. After cleaning for a period of time, it is switched under the control of the controller 53, ensuring thorough cleaning of the clamping position;

[0067] After the clamping is completed, the control valve 2 62 starts to work, opens the valve, enables the cleaning liquid to enter the inner pipe 61, and then can push the inner pipe 61 to move outward, and then pushes the inner pipe 61 along the central hole of the wheel hub to the outside of the wheel hub. Under the action of the torsion spring 68, the compensation pipe 67 quickly pops open and rinses the outside of the wheel hub. The setting of the spring 1 65 ensures the subsequent reset of the inner pipe 61 and the compensation pipe 67;

[0068] During the entire cleaning process, the controller 53 monitors the working status of each component in real time and adjusts the cleaning liquid flow rate as needed to ensure the optimization of the cleaning effect. After the cleaning is completed, through the cooperation of the water pump inside the water tank and the control valve 1 43, clean water starts to be injected into the cleaning pipe 11 to perform secondary cleaning on the wheel hub;

[0069] After the cleaning is completed, the controller 53 issues an instruction to make the electric push rod 1 81 move in the reverse direction, driving the displacement plate 72 and the clamping plate 13 to reset. At the same time, the water flow in the cleaning pipe 11 stops, and the scraping plate 12 and the ejecting member 6 also return to the initial position. The manipulator 10 drives the cleaning pipe 11 and its attached components to reset as a whole, preparing for the next cleaning operation.
