Description

Technical Field

[0001] The invention relates to the technical field of cleaning and rust removal of brake discs, and more specifically to a rotary cleaning type anti-rust spraying mechanism for brake discs. Background Art

[0002] As a key component in the automobile braking system, the surface treatment process of the brake disc has an important impact on the safety and performance of the vehicle. During the production and processing of the brake disc, it undergoes sand core forming, melt forging and casting, shot blasting, CNC drilling, cleaning and rust prevention, spraying and drying, packaging and warehousing to complete the production process of the brake disc. The cleaning and rust prevention operation process of the brake disc is mostly done manually to remove impurities such as iron filings on the surface of the brake disc, and then spray anti-rust oil on the brake disc to complete the cleaning and rust prevention process of the brake disc.

[0003] After searching, the patent number CN113044570A discloses "a brake disc processing production line and its process flow". The ring conveyor chain drives the brake disc to pass between two discs. The two disc surfaces of the brake disc correspond to the two discs respectively. The anti-rust oil is sprayed on the brake disc from both sides to clean the impurities on the surface of the brake disc and spray the anti-rust oil onto the brake disc. However, according to Figure 2 , Figure 3 It can be seen that the brake disc is installed on the rubber pad. After the brake pad is installed, the cross bar, support bar and vertical bar are arranged on one side of the brake disc, which will block one side of the brake disc. The anti-rust oil sprayed from the spray holes in the upper and lower directions of the disc will be contaminated on the structure other than the brake disc, and the anti-rust oil that is not easy to spray will be evenly adhered to the brake disc; moreover, after the brake disc moves outside the rust removal box, the anti-rust oil attached to other structures is easy to drip outside the rust removal box. In addition, the brake disc moves horizontally and is decontaminated by the rust removal oil that is continuously fed. On the one hand, compared with the use of special cleaning fluid for decontamination, the rust prevention oil may not be able to effectively remove surface dirt and impurities. On the other hand, the amount of rust removal oil used and the amount of filtration are increased, and there are certain processing defects.

[0004] Therefore, we propose a rotary cleaning brake disc anti-rust spraying mechanism in view of the existing problems. Summary of the invention

In addition, the cleaning station, the oiling station and the drying station are all fixed with driving motors that can be driven horizontally inside and outside and magnetically docked with the positioning sleeve.

After the brake disc is mounted on the positioning sleeve, the inner end wall of the brake disc is adsorbed and positioned by utilizing the cooperation between the pump, the adsorption tube and the positioning sleeve, so that the brake disc is stably installed on the positioning sleeve.

[0008] Furthermore, the upper end of the collecting hood and the end away from the adsorption tube are both opened, and the inner bottom wall of the collecting hood is inclined downward toward the adsorption tube, which is used to collect the cleaning liquid and rust removal oil sprayed on the brake disc and discharge them outward from the drainage pipe.

[0009] Furthermore, a plurality of support brackets corresponding to the positions of the mounting brackets are fixed on the outer end wall of the operating table, an electric guide rail for horizontally driving the drive motor is fixedly installed on the support bracket, a magnetic column is fixed on the driving end of the drive motor, and a magnetic cavity for magnetically docking with the magnetic column is opened on the outer end wall of the positioning sleeve.

[0011] Furthermore, the upper end wall of the operating table is provided with an annular groove corresponding to the position of the drain pipe, and the annular groove is provided with a reflux hole 1 and a reflux hole 2 which are open at the lower end and are arranged perpendicular to each other, and the reflux hole 1 and the reflux hole 2 correspond to the positions of the liquid drain pipe and the oil drain pipe respectively.

[0012] Furthermore, a liquid filter cartridge and an oil filter cartridge are fixedly installed on the bottom end wall of the operating table and are respectively connected to the reflux hole 1 and the reflux hole 2, and filter screens are embedded in the liquid filter cartridge and the oil filter cartridge.

On the one hand, the cleaning effect is improved. After cleaning, anti-rust oil is sprayed to improve the rust removal effect. On the other hand, the use of anti-rust oil is reduced, and subsequent filtering of anti-rust oil that is excessively mixed with impurities is effectively avoided. After cleaning, air drying is immediately carried out so that the surface of the brake disc rotating to the oiling station is in a dry state to avoid residual moisture affecting the spraying effect of the anti-rust oil.

[0018] The following will combine the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all the embodiments. All other embodiments obtained by ordinary technicians in this field without creative work based on the embodiments of the present invention belong to the scope of protection of the present invention.

[0019] Example 1: The present invention discloses a rotary cleaning brake disc anti-rust spraying mechanism, see Figure 1-Figure 3 , including a rotating column 2 that is rotationally driven and mounted on an operating table 1, a rotating motor for rotating the rotating column 2 is fixed to the bottom end wall of the operating table 1, and limiting components for mounting a brake disc 6 are installed on the end walls around the rotating column 2; The limiting assembly includes an adsorption tube 3 fixedly embedded on the rotating column 2, and a positioning sleeve 5 connected with the adsorption tube 3 and used for adsorbing and nesting the brake disc 6 is rotatably installed at the outer end of the adsorption tube 3, and the positioning sleeve 5 is connected and rotatably connected with the adsorption tube 3 through a rotating joint; See also Figure 2 and Figure 4-Figure 6 , adsorption holes 501 connected to the interior of the positioning sleeve 5 are provided on the end walls around the middle part thereof, a pump connected to a plurality of adsorption tubes 3 is embedded in the rotating column 2, and a solenoid valve is embedded in the inner end of the adsorption tube 3, and an exhaust pipe with an exhaust valve is externally connected to the outer end of the adsorption tube 3; After the brake disc 6 is mounted on the positioning sleeve 5, the inner end wall of the brake disc 6 is adsorbed and positioned by utilizing the cooperation between the pump adsorption tube 3 and the positioning sleeve 5, so that the brake disc 6 can be stably installed on the positioning sleeve 5, and the solenoid valves on each adsorption tube 3 and the exhaust pipe with an exhaust valve are utilized to achieve independent adsorption and exhaust work of each 3.

[0020] See also Figure 5-Figure 7 A collecting hood 4 located outside the positioning sleeve 5 is fixedly sleeved on the end wall of the adsorption tube 3 close to the positioning sleeve 5, and a drain pipe 7 is externally connected to the bottom end wall of the collecting hood 4. A downwardly disposed liquid drain pipe 701 and an oil drain pipe 702 are installed on the drain pipe 7. An opening is provided at the upper end of the collecting hood 4 and at the end away from the adsorption tube 3, and the inner bottom wall of the collecting hood 4 is inclined downward toward the adsorption tube 3, so as to collect the cleaning liquid and rust removing oil sprayed onto the brake disc 6 and discharge them outwardly through the drain pipe 7.

[0021] See also Figure 1-Figure 2 as well as Figure 8-Figure 9 One side of the operating platform 1 is used as a loading and unloading station for the brake disc 6. The other three stations of the operating platform 1 away from the loading and unloading station are respectively a cleaning station, an oiling station and a drying station distributed along the circumferential direction. The cleaning station, the oiling station and the drying station are all fixed with mounting frames 11. A pair of liquid spray pipes 12, an oil spray pipe 14 and an air jet pipe 16 located on both sides of the top of the brake disc 6 are respectively installed on the multiple mounting frames 11; See also Figure 8 A pair of jet pipes 16 are also fixed on the end wall on the other side of the mounting frame 11 on which the spray pipe 12 is fixed. The two pairs of jet pipes 16 are respectively connected to a blower 17 which is also fixed on a supporting frame corresponding to their positions. The lower ends of the pair of spray pipes 12, the oil injection pipe 14, and the jet pipe 16 are respectively arranged to be inclined downward toward the top end wall of the brake disc 6.

[0022] The cleaning station, the oiling station and the drying station are all fixed with a driving motor 9 that can be driven horizontally inside and outside and is magnetically docked with the positioning sleeve 5. A plurality of supporting brackets corresponding to the position of the mounting bracket 11 are fixed on the outer peripheral end wall of the operating table 1. The supporting bracket is fixed with an electric guide rail 8 for horizontally driving the driving motor 9. A magnetic column 10 is fixed to the driving end of the driving motor 9. A magnetic cavity 502 is opened on the outer end wall of the positioning sleeve 5 to be magnetically docked with the magnetic column 10. In the initial state, the driving motor 9 is away from the edge of the operating table 1 under the action of the electric guide rail 8. When the rotating column 2 drives the brake disc 6 on the positioning sleeve 5 to rotate to each station, the electric guide rail 8 is used to drive the driving motor 9 inward until the magnetic column 10 is inserted into the magnetic cavity 502 of the positioning sleeve 5, so as to realize the fixed installation between the driving motor 9 and the positioning sleeve 5. The positioning sleeve 5 and the magnetic column 10 are magnetically connected. An electromagnetic sheet can be embedded in the magnetic column 10 to open and close the electromagnetic sheet and select the magnetic condition of the magnetic column 10. By starting the driving motor 9, the brake disc 6 on the positioning sleeve 5 can be driven to rotate in a circle. The liquid spray pipe 12, the oil spray pipe 14 and the air jet pipe 16 located at each station act on both sides of the top of the brake disc 6. During the rotation of the brake disc 6, the cleaning liquid, rust-removing oil and the drying airflow are evenly diffused to the entire circumferential end surface of the brake disc 6, that is, the cleaning, oiling and drying work are completely acted on the entire circumferential end surface of the brake disc 6, effectively improving the processing effect of the brake disc 6. The cleaning liquid and rust-proof oil sprayed downward are separately collected and discharged by the collecting cover 4 and filtered and recycled, which will not cause a burden on the recycling; The whole process is carried out synchronously and intermittently at each station. Please refer to Fig.10 , a rotary multi-station cycle production mode is set up. Compared with the existing conveyor chain production mode, each station is carried out synchronously and cyclically, achieving the design goals of unified transmission system, centralized assembly space and efficient production process.

[0023] In addition, it should be added that in order to save costs, the jet pipe 16 and the blower 17 arranged on the drying station can be arranged in a coordinated structure on the oiling station. The layout of the jet pipe 16 and the oil spray pipe 14 is consistent with the layout of the jet pipe 16 and the liquid spray pipe 12. After the anti-rust oil spraying work, spray drying is immediately carried out to remove the electric guide rail 8 and the drive motor 9 on the drying station, thereby reducing the cost expenditure of the electric guide rail 8 and the drive motor 9 on the drying station. The original drying station was defined as the unloading station, and the original loading and unloading work was defined as the loading station.

[0024] Embodiment 2: In this embodiment, under the effect of embodiment 1, the recovery process of cleaning liquid and anti-rust oil is optimized, as follows: See also Figure 2A pair of liquid spray pipes 12 are externally connected to a liquid storage tank 13 fixed on a support frame, and a pair of oil spray pipes 14 are externally connected to an oil storage pipe 15 fixed on another support frame; See also Figure 4 , Figure 5 An annular groove 101 corresponding to the position of the drain pipe 7 is provided on the upper end wall of the operating table 1, and a reflux hole 102 and a reflux hole 103 which are open at the lower end and are arranged perpendicularly to each other are provided on the annular groove 101, and the reflux hole 102 and the reflux hole 103 correspond to the positions of the drain pipe 701 and the oil drain pipe 703 respectively, and a liquid filter cartridge 18 and an oil filter cartridge 19 which are arranged in communication with the reflux hole 102 and the reflux hole 103 respectively are fixedly installed on the bottom end wall of the operating table 1; See also Figure 8 , Fig. 9 , the filter cylinder 18 and the oil filter cylinder 19 are both embedded with filter screens, the bottom ends of the filter cylinder 18 and the oil filter cylinder 19 are respectively connected to the liquid storage tank 13 and the oil storage pipe 15 through a return pipe, and a hydraulic pump is installed on the return pipe; When cleaning and anti-rust oil spraying operations are performed separately, the cleaning liquid sprayed toward the brake disc 6 by the pair of liquid spraying pipes 12 finally falls into the collecting cover 4 from the lower end of the brake disc 6, and is discharged toward the drain pipe 7 along the inner bottom wall of the collecting cover 4. The oil drain pipe 702 on the cleaning station is closed, and the cleaning liquid is introduced into the blower 17 through the drain pipe 701 and the reflux hole 102, and is filtered and processed by the blower 17 and then re-introduced into the liquid storage tank 13 through the reflux pipe; At the oiling station, the drain pipe 701 is closed, and the cleaning liquid sprayed toward the brake disc 6 by a pair of oil spray pipes 14 finally falls from the lower end of the brake disc 6 into the collecting cover 4 there, and is discharged toward the outside of the drain pipe 7 along the inner bottom wall of the collecting cover 4. The cleaning liquid is introduced into the filter cylinder 18 through the drain pipe 702 and the reflux hole 103, and after being filtered by the blower 17, it is re-introduced into the oil storage pipe 15 through the reflux pipe.

[0025] Compared with the decontamination work directly performed by spraying anti-rust oil, before spraying the rust-removing oil, the sprayed cleaning liquid is used to remove oil, dust and other impurities, which improves the cleaning effect on the one hand. After cleaning, the anti-rust oil is sprayed to improve the rust removal effect, and on the other hand, the use of the anti-rust oil is reduced, effectively avoiding the subsequent filtering treatment of the anti-rust oil that is excessively mixed with impurities. In addition, a collecting cover 4 is provided at the positioning sleeve 5, which rotates synchronously with the positioning sleeve 5, and is used to separately collect the cleaning liquid and anti-rust oil that are processed once, effectively avoiding the cleaning liquid and rust-removing oil from being brought to other parts.

[0026] In summary, a rotary multi-station operating table 1 is provided, on which a rotating column 2 with limit assemblies on all sides is rotatably installed, and the limit assemblies are used to nest and position the brake disc 6. The loading and unloading stations, cleaning stations, oiling stations and drying stations are divided around the operating table 1, and a pair of liquid spray pipes 12, oil spray pipes 14 and air jet pipes 16 are arranged on both sides above the brake disc 6 for the cleaning station, oiling station and drying station, respectively, so as to facilitate the cleaning, oiling and drying of the positioned brake disc 6 in succession along the circumferential direction, and a drive motor 9 is arranged for horizontal driving and installation in contact with the positioning sleeve 5. During the cleaning, oiling and drying process, the brake disc 6 on the positioning sleeve 5 is driven by the drive motor 9 to rotate, which is conducive to the cleaning, oiling and drying work acting on the entire circumferential end surface of the brake disc 6, and effectively improves the processing effect of the brake disc 6; A cleaning station is set before the oiling station. A pair of spray pipes 12 and a pair of air jet pipes 16 are set on the cleaning station. The pair of spray pipes 12 is used to clean the rotating brake disc 6 in the circumferential direction. Compared with the decontamination work directly by spraying anti-rust oil, the sprayed cleaning liquid is used to remove oil, dust and other impurities. On the one hand, the cleaning effect is improved. After cleaning, anti-rust oil is sprayed to improve the rust removal effect. On the other hand, the use of anti-rust oil is reduced. The cleaning liquid and anti-rust oil sprayed downward are collected by the collecting cover 4 and discharged for separate filtration and recovery treatment, which effectively prevents the cleaning liquid and rust removal oil from being brought to other parts.

[0027] The above are only preferred specific implementation modes of the present invention; however, the protection scope of the present invention is not limited thereto; any technician familiar with the technical field within the technical scope disclosed by the present invention; any equivalent replacement or change based on the technical solution and improved concept of the present invention shall be covered within the protection scope of the present invention.
