Description

Technical Field

[0001] This invention relates to the field of steering wheel processing technology, specifically to an integrated steering wheel anchoring and oiling device and its usage method. Background Technology

[0002] In the manufacturing process of steering wheels, the steering wheel joints must first be riveted and fixed, and then rust-preventive oil must be applied to the spline area to ensure the assembly accuracy and service life of the steering wheel. Currently, the common method is to manually apply rust-preventive oil to the spline using hand tools. This manual operation method has many drawbacks: First, the amount of coating is difficult to control precisely; too much will lead to waste and pollution, while too little will result in poor rust prevention; second, the application point and uniformity depend on the operator's experience and sense of responsibility, resulting in poor quality stability; finally, manual operation is inefficient, taking about 4.5 seconds to complete the coating of one product, increasing the time and labor costs per piece. In addition, during manual coating, the rust-preventive oil is prone to dripping and splashing, which cannot be recycled, resulting in resource waste and increased production costs.

[0003] Therefore, there is an urgent need for a device that can integrate the riveting and oiling processes to achieve automated coating, in order to solve the problems of unstable quality, low efficiency and high cost in the existing technology. Summary of the Invention

[0005] (II) Technical Solution To achieve the above objectives, the present invention provides the following technical solution: an integrated steering wheel anchoring and oiling device, comprising a base box, a fixed box, a hydraulic pump station, and a controller, and further comprising a coating device and a rust-preventive oil recovery system; the fixed box is fixed to one side of the top of the base box, and a workbench is fixedly connected to the top of the base box; a hydraulic cylinder is vertically fixedly connected to the top of the inner wall of the fixed box; the working end of the hydraulic cylinder extends to the outside of the fixed box and is fixedly connected to a mounting plate; a riveting head is fixedly connected to the bottom of the mounting plate and directly above the workbench; the hydraulic cylinder is connected to the hydraulic pump station via an oil pipe; a pressure plate is horizontally fixedly connected to one side of the mounting plate; a fixed bracket is fixedly connected to one side of the fixed box; and a contact switch is fixedly connected inside the fixed bracket and below the pressure plate. The coating device is located on one side of the workbench. The rust-preventive oil recovery system includes a recovery tray located at the bottom of the workbench and an oil tank located at the bottom of the inner wall of the base box. An oil pump is also installed in the oil tank. A recovery drain hole is provided at the top of the base box and at the corresponding position on the workbench. The bottom of the recovery tray is connected to the oil tank through a return oil pipe. The controller is electrically connected to the hydraulic pump station, contact switch, oil pump and coating device.

[0006] Preferably, a protective frame is fixedly connected to the top of the base box and to the periphery of the workbench, a fixed cylinder is fixedly connected to the bottom of the fixed box, a guide cylinder is slidably connected inside the fixed cylinder, the bottom end of the guide cylinder is fixedly connected to the top of the mounting plate, and a filter is provided at the top of the oil tank and at the end of the return oil pipe.

[0007] Preferably, the coating device includes a spray gun, a bracket, and a first solenoid valve. The spray gun is fixed to one side of the base box by the bracket. The spray direction of the spray gun is aligned with the spline position of the product. The oil pump is connected to the spray gun through an oil supply pipe. The first solenoid valve is connected in series with the oil supply pipe. The control terminal of the first solenoid valve is electrically connected to the output terminal of the controller.

[0008] Preferably, the bracket includes a fixed plate, an adjusting bracket, and a mounting bracket. The fixed plate has mounting holes on its surface and is fixed to one side of the base box. The adjusting bracket and the mounting bracket are L-shaped. The adjusting bracket is disposed between the fixed plate and the mounting bracket. The adjusting bracket has a first strip-shaped hole and a second strip-shaped hole on its surface. The mounting bracket has a third strip-shaped hole on the side near the second strip-shaped hole. The other side of the mounting bracket has a mounting notch.

[0009] In another preferred embodiment, the coating device includes an oil-dipping tank, a coating head, a lifting cylinder, a 180-degree rotating cylinder, a second solenoid valve, and a third solenoid valve. The cylinder body of the lifting cylinder is fixed to one side of the top of the base box, and the piston rod of the lifting cylinder is connected to the cylinder body of the 180-degree rotating cylinder. The output shaft of the 180-degree rotating cylinder is fixedly connected to an mounting arm. The coating head is fixed to one side of the mounting arm. The oil-dipping tank is fixedly installed on one side of the base box and located directly below the coating head in its initial position. The second solenoid valve is connected to the lifting cylinder through an air pipeline, and the third solenoid valve is connected to the 180-degree rotating cylinder through an air pipeline. The control terminals of the second and third solenoid valves are electrically connected to the output terminals of the controller, respectively.

[0010] Preferably, the oil pump is connected to the bottom of the oil dipping tank via an oil pipe, an overflow pipe is provided on one side of the oil dipping tank, a guide telescopic rod is vertically provided at the bottom inside the oil dipping tank, an oil filter plate is fixedly connected to the top of the guide telescopic rod, a spring is also provided between the oil dipping tank and the oil filter plate, the overflow pipe is located below the oil filter plate when it is not subjected to external force, and the surface of the oil filter plate is provided with filter holes.

[0011] A method of using the above-mentioned integrated steering wheel anchoring and oiling equipment includes the following steps: S1: Preparation: Place the workpiece on the riveting station of the worktable; S2: Perform riveting: Start the hydraulic pump station through the controller to drive the hydraulic cylinder to move the riveting head downward. When the pressure plate touches the contact switch, the hydraulic cylinder stops moving and the riveting head completes the riveting operation on the workpiece. S3: Trigger coating: After the riveting operation is completed, the controller controls the hydraulic pump station to reset the hydraulic cylinder, the riveting head rises and drives the pressure plate to separate from the contact switch, the contact switch is reset and sends a signal to the controller; S4: Perform oiling: After receiving the signal, the controller controls the coating device to apply anti-rust oil to the spline part of the workpiece that has been riveted. S5: Complete the work: After coating is completed, remove the processed workpiece; S6: Oil recovery: Rust-preventive oil dripping during the coating process is collected by the recovery tray through the recovery drain and flows back to the oil tank through the return oil pipe.

[0012] Preferably, when the coating device uses a spray gun, the oiling process in step S4 is as follows: the controller starts the oil pump and opens the first solenoid valve, the rust-preventive oil is delivered to the spray gun through the oil supply pipe, and the spray gun sprays the workpiece spline area; after a preset spraying time, the controller closes the first solenoid valve and the oil pump.

[0013] Preferably, when the coating device uses a coating head, the oiling process in step S4 specifically involves: S4.1: The controller controls the second solenoid valve to move, driving the lifting cylinder to descend, which in turn causes the coating head to press down on the filter plate in the oil dipping tank, causing the filter plate to compress the spring and sink until the coating head contacts the surface of the rust-preventive oil to pick up the rust-preventive oil. S4.2: The controller controls the second solenoid valve to reset and drives the lifting cylinder to rise slowly at a constant speed. During the rising process, the oil filter plate moves upward under the action of the spring return force, and generates relative movement with the rising coating head, thereby squeezing and scraping off excess anti-rust oil on the surface of the coating head, so that the coating head carries a uniform and quantitative oil film. S4.3: After the coating head rises to the set height, the controller controls the third solenoid valve to drive the 180-degree rotary cylinder to rotate 180°, so that the coating head carrying a quantitative oil film is moved from the oiling station to the oiling station above the spline of the workpiece. S4.4: The controller controls the second solenoid valve to drive the lifting cylinder to descend, so that the coating head contacts and coats the spline area of ​​the workpiece, completing the quantitative coating. S4.5: The controller controls the second solenoid valve to reset, drives the lifting cylinder to rise, and then controls the third solenoid valve to reset, drives the 180-degree rotating cylinder to rotate in the opposite direction, so that the coating head returns to the initial position above the oil dipping tank.

[0014] Preferably, after step S6, step S7 is also included: oil circulation, the controller periodically starts the oil pump to pump the filtered rust-preventive oil in the oil tank into the bottom of the oil dipping tank, and the excess rust-preventive oil flows back to the oil tank through the overflow pipe to maintain a constant liquid level in the oil dipping tank.

[0015] (III) Beneficial Effects Compared with the prior art, the present invention has the following beneficial effects: 1. By setting up contact switches and controllers and electrically connecting them to the hydraulic pump station and coating device, the automated linkage control of the riveting and oiling processes is realized, which can completely eliminate the manual coating process and significantly improve work efficiency and consistency.

[0016] 2. If a spray gun coating device is used, the spray gun can be fixed with a multi-directional adjustable bracket, which can accurately align and cover the spline coating points. At the same time, combined with the controller to control the opening and closing time of the first solenoid valve and the oil pump, the spray volume can be accurately managed, effectively ensuring the coating quality.

[0017] 3. If a contact coating device is used, and a quantitative oil control mechanism consisting of a guide rod, an oil filter plate, and a spring is specially set up, the excess oil on the surface of the coating head can be automatically removed by the squeezing and scraping action of the oil filter plate during the upward process after the coating head is dipped in oil. This allows the coating head to carry a uniform and quantitative oil film for coating, fundamentally solving the problems of uneven coating amount and dripping.

[0018] 4. By setting up a rust-preventive oil recovery system that includes a recovery tray, return oil pipe, oil tank and filter, excess rust-preventive oil dripping during the coating process can be automatically collected, filtered and recycled, which can reduce oil consumption and production costs, and also meet the requirements of green and environmentally friendly manufacturing.

[0019] 5. By integrating both spray gun and contact coating options into the equipment, users are provided with flexible choices to meet different product requirements and production cycles, thus expanding the applicability and practicality of the equipment. Attached Figure Description

[0022] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0023] Example 1: Spray gun coating device like Figure 1 and Figure 2As shown, an integrated steering wheel anchoring and oiling device includes a base box 1, a fixed box 2, a hydraulic pump station 7, and a controller 16, as well as a coating device and a rust-preventive oil recovery system. The fixed box 2 is fixed to one side of the top of the base box 1. A workbench 3 is also fixedly connected to the top of the base box 1. A hydraulic cylinder 4 is vertically fixedly connected to the top of the inner wall of the fixed box 2. The working end of the hydraulic cylinder 4 extends to the outside of the fixed box 2 and is fixedly connected to a mounting plate 5. A riveting head 6 is fixedly connected to the bottom of the mounting plate 5 and directly above the workbench 3. The hydraulic cylinder 4 is connected to the hydraulic pump station 7 through an oil pipe. The hydraulic pump station 7 has a corresponding solenoid valve. The hydraulic cylinder 4 drives the mounting plate 5 and the riveting head 6 to move up and down to complete the riveting action. A pressure plate 8 is horizontally fixedly connected to one side of the mounting plate 5. A fixed bracket 9 is fixedly connected to one side of the fixed box 2. A contact switch 10 is fixedly connected inside the fixed bracket 9 and below the pressure plate 8. By adjusting the installation height of the contact switch 10 on the fixed bracket 9, the downward stroke and termination position of the riveting head 6 can be flexibly set and adjusted. The up-and-down movement of the fixed plate 5 drives the up-and-down movement of the pressure plate 8. When the pressure plate 8 touches the contact switch 10, the contact switch 10 sends a signal to the controller 16. The controller 16 then instructs the hydraulic pump station 7 to stop driving the hydraulic cylinder 4, so that the riveting head 6 stops precisely at the set riveting depth. It can achieve precise control of the riveting force required for workpieces of different specifications. The structure is simple and reliable and easy to adjust.

[0024] A protective frame 29 is fixedly connected to the top of the base box 1 and around the perimeter of the workbench 3 to prevent the rust-preventive oil from flowing outside the workbench 3 and to ensure that the rust-preventive oil can be recycled. A fixed cylinder 30 is fixedly connected to the bottom of the fixed box 2. A guide cylinder 31 is slidably connected inside the fixed cylinder 30. The bottom end of the guide cylinder 31 is fixedly connected to the top of the mounting plate 5 to ensure the vertical movement of the mounting plate 5. A filter 14 is installed at the top of the oil tank 12 and at the end of the return oil pipe 13. The filter 14 can be made of PP cotton or other materials to prevent impurities from mixing with the rust-preventive oil.

[0025] The coating device is located on one side of the workbench 3. The rust-preventive oil recovery system includes a recovery tray 11 located at the bottom of the workbench 3 and an oil tank 12 located at the bottom of the inner wall of the base box 1. An oil pump 15 is also installed in the oil tank 12. A recovery drain hole is provided at the top of the base box 1 and at the corresponding position on the workbench 3. The bottom of the recovery tray 11 is connected to the oil tank 12 through a return oil pipe 13. The controller 16 is electrically connected to the hydraulic pump station 7, the contact switch 10, the oil pump 15 and the coating device.

[0026] The coating device includes a spray gun 17, a bracket 18, and a first solenoid valve 19. The spray gun 17 is fixed to one side of the base box 1 by the bracket 18. The spray direction of the spray gun 17 is aligned with the spline position of the product. The oil pump 15 is connected to the spray gun 17 through the oil supply pipe. The first solenoid valve 19 is connected in series to the oil supply pipe. The control terminal of the first solenoid valve 19 is electrically connected to the output terminal of the controller 16. The amount of oil sprayed is controlled by controlling the working time of the oil pump 15 and the first solenoid valve 19.

[0027] The bracket 18 is made of iron and includes a fixed plate 181, an adjusting bracket 182, and a mounting bracket 183. The fixed plate 181 has mounting holes on its surface and is fixed to one side of the base box 1. The adjusting bracket 182 and the mounting bracket 183 are L-shaped. The adjusting bracket 182 is positioned between the fixed plate 181 and the mounting bracket 183. The surface of the adjusting bracket 182 has a first strip hole 184 and a second strip hole 185. The mounting bracket 183 has a third strip hole 186 on the side near the second strip hole 185. The other side of the mounting bracket 183 has a mounting notch 187. The length direction of the first strip hole 184 is vertical, and the length direction of the second strip hole 185 is front-back. The fixed plate 181 and the adjusting bracket 182, as well as the adjusting bracket 182 and the mounting bracket 183, are fixed by bolts in the long strip holes. The long strip holes allow adjustment of the height and front-back position of the end spray gun 17, facilitating the alignment of the spray gun 17 with the spline position. Of course, the L-shaped structure of the adjusting bracket 182 and the mounting bracket 183 can be adjusted under the action of external force to form an acute or obtuse angle, making the spray direction more precise. The thickness of the adjusting bracket 182 and the mounting bracket 183 is greater than 5mm to ensure that they will not deform during normal use.

[0028] When using it, follow these steps: S1: Preparation: Place the workpiece on the riveting station of workbench 3; S2: Perform riveting: The hydraulic pump station 7 is started by the controller 16, which drives the hydraulic cylinder 4 to move the riveting head 6 downward. The pressure plate 8 touches the contact switch 10, the hydraulic cylinder 4 stops moving, and the riveting head 6 completes the riveting operation on the workpiece. S3: Trigger coating: After the riveting operation is completed, the controller 16 controls the hydraulic pump station 7 to reset the hydraulic cylinder 4, the riveting head 6 rises and drives the pressure plate 8 to separate from the contact switch 10, the contact switch 10 resets and sends a signal to the controller 16; S4: Perform oiling: After receiving the signal, the controller 16 controls the coating device to operate. The controller 16 starts the oil pump 15 and opens the first solenoid valve 19. The rust-preventive oil is delivered to the spray gun 17 through the oil supply pipe and sprayed onto the spline part of the workpiece by the spray gun 17. After a preset spraying time, such as 0.3-0.6 seconds, the controller 16 closes the first solenoid valve 19 and the oil pump 15 to apply rust-preventive oil to the spline part of the workpiece that has been riveted. S5: Complete the work: After coating is completed, remove the processed workpiece; S6: Oil recovery: Rust-preventive oil dripping during the coating process is collected by the recovery tray 11 through the recovery drain hole and flows back to the oil tank 12 through the return oil pipe 13.

[0029] Example 2: Contact Coating Apparatus like Figures 3 to 5 As shown, the main difference between this embodiment and Embodiment 1 lies in the coating device. The coating device in this embodiment is a contact type, comprising an oil-dipping tank 20, a coating head 21, a lifting cylinder 22, a 180-degree rotating cylinder 23, a second solenoid valve, and a third solenoid valve. One side of the coating head 21 is configured as a sponge or brush. The cylinder body of the lifting cylinder 22 is fixed to the top side of the base box 1. The piston rod of the lifting cylinder 22 is connected to the cylinder body of the 180-degree rotating cylinder 23. The output shaft of the 180-degree rotating cylinder 23 is fixedly connected to a mounting arm 24. The coating head 21 is fixed to the bottom side of the mounting arm 24. The surface of the mounting arm 24 is provided with mounting slots along its length to facilitate adjustment of the mounting position of the coating head 21.

[0030] The oil-dipping tank 20 is fixedly installed on one side of the base box 1 and located directly below the coating head 21 at the initial position. The second solenoid valve is connected to the lifting cylinder 22 through the air pipeline, and the third solenoid valve is connected to the 180-degree rotating cylinder 23 through the air pipeline. The control terminals of the second and third solenoid valves are electrically connected to the output terminals of the controller 16, respectively. The second and third solenoid valves are not shown in the figure. The air pipeline is connected to a high-pressure air source, which is usually gas generated by an air compressor.

[0031] The oil pump 15 is connected to the bottom of the oil dipping tank 20 through an oil pipe. An overflow pipe 25 is provided on one side of the oil dipping tank 20. A guide telescopic rod 26 is vertically installed at the bottom inside the oil dipping tank 20. An oil filter plate 27 is fixedly connected to the top of the guide telescopic rod 26. A spring 28 is also provided between the oil dipping tank 20 and the oil filter plate 27. The spring 28 is sleeved on the surface of the guide telescopic rod 26. The guide telescopic rod 26 is made of two round tubes with matching inner and outer diameters and slidably connected. The overflow pipe 25 is located below the oil filter plate 27 when it is not subjected to external force, which ensures the oil level. The surface of the oil filter plate 27 is provided with filter holes. The guide telescopic rod 26 ensures that the oil filter plate 27 can move up and down.

[0032] Driven by the lifting cylinder 22, the coating head 21 descends, first pressing the oil filter plate 27 to cause its compression spring 28 to sink. Then, the coating head 21 itself is immersed in the rust-preventive oil, ensuring its surface is fully saturated with the oil. After being dipped in oil, the coating head 21 rises, and the compressed spring 28 pushes the oil filter plate 27 to move upward synchronously. Due to the relative movement between the oil filter plate 27 and the coating head 21, the edges and mesh of the oil filter plate 27 exert a squeezing and scraping effect on the surface of the coating head 21, forcibly scraping away any excess or dripping oil absorbed by the coating head 21, forcing it to flow back into the tank through the holes of the oil filter plate 27. After being squeezed and scraped by the oil filter plate 27, only a uniform and quantitative oil film remains on the surface of the coating head 21, which is in an optimal and controlled oil-carrying state. Then the coating head 21 rotates to the top of the spline of the workpiece and contacts it. Through the contact pressure, the quantitative oil film on the coating head 21 is evenly transferred to the tooth surface of the spline, thereby completing a precise dosage coating.

[0033] When using it, follow these steps: S1: Preparation: Place the workpiece on the riveting station of workbench 3; S2: Perform riveting: The hydraulic pump station 7 is started by the controller 16, which drives the hydraulic cylinder 4 to move the riveting head 6 downward. The pressure plate 8 touches the contact switch 10, the hydraulic cylinder 4 stops moving, and the riveting head 6 completes the riveting operation on the workpiece. S3: Trigger coating: After the riveting operation is completed, the controller 16 controls the hydraulic pump station 7 to reset the hydraulic cylinder 4, the riveting head 6 rises and drives the pressure plate 8 to separate from the contact switch 10, the contact switch 10 resets and sends a signal to the controller 16; S4: Perform oiling: After receiving the signal, the controller 16 controls the coating device to operate. The operation of the coating device is as follows: S4.1: The controller 16 controls the second solenoid valve 32 to operate, driving the lifting cylinder 22 to descend, which in turn drives the coating head 21 to press down on the oil filter plate 27 in the oil dipping tank 20, causing the oil filter plate 27 to compress the spring 28 and sink down until the coating head 21 contacts the surface of the rust-preventive oil to pick up the rust-preventive oil. S4.2: The controller 16 controls the second solenoid valve 32 to reset and drives the lifting cylinder 22 to rise slowly at a constant speed. During the rising process, the oil filter plate 27 moves upward under the action of the spring 28's restoring force, and generates relative movement with the rising coating head 21, thereby squeezing and scraping off excess anti-rust oil on the surface of the coating head 21, so that the coating head 21 carries a uniform and quantitative oil film. S4.3: After the coating head 21 rises to the set height, the controller 16 controls the third solenoid valve 33 to operate, driving the 180-degree rotary cylinder 23 to rotate 180°, so that the coating head 21 carrying a quantitative oil film is moved from the oiling station to the oiling station above the spline of the workpiece. S4.4: Controller 16 controls the second solenoid valve 32 to operate, driving the lifting cylinder 22 to descend, so that the coating head 21 contacts and coats the spline part of the workpiece, completing the quantitative coating. S4.5: Controller 16 controls the second solenoid valve 32 to reset, drives the lifting cylinder 22 to rise, and then controls the third solenoid valve 33 to reset, drives the 180-degree rotating cylinder 23 to rotate 180° in the opposite direction, so that the coating head 21 returns to the initial position above the oil dipping tank 20, and applies anti-rust oil to the spline part of the workpiece that has been riveted. S5: Complete the work: After coating is completed, remove the processed workpiece; S6: Oil recovery: Rust-preventive oil dripping during the coating process is collected by the recovery tray 11 through the recovery drain hole and flows back to the oil tank 12 through the return oil pipe 13; S7: Oil circulation: The controller 16 periodically starts the oil pump 15 to pump the filtered rust-preventive oil in the oil tank 12 into the bottom of the oil dipping tank 20. Excess rust-preventive oil flows back to the oil tank 12 through the overflow pipe 25 to maintain a constant liquid level in the oil dipping tank 20.
