Description
Technical Field
[0001] This invention relates to the technical field of rust prevention treatment, and more specifically to a rust prevention treatment device for automotive parts. Background Technology
[0002] In automobile manufacturing and repair, precision metal parts such as brake wheel cylinders are highly susceptible to corrosion due to environmental moisture and residual cutting fluid during processing, storage, or transportation, severely impacting their performance and service life. Therefore, efficient and thorough rust prevention treatment is crucial for these parts. Currently, commonly used rust prevention processes include spray cleaning and immersion in rust-preventive oil, but these methods generally suffer from incomplete cleaning, difficulty in effectively covering internal cavities and threaded holes, low automation, and poor oil circulation.
[0003] Existing rust prevention equipment mostly adopts fixed immersion or one-way rinsing methods, which cannot achieve all-round cleaning of complex structural workpieces (such as those with deep holes, threaded holes, and cavities). At the same time, the workpiece clamping structure is simple, which can easily cause clamping damage or inaccurate positioning. In addition, impurities such as sludge and iron filings after cleaning are easily deposited at the bottom of the pool, and long-term accumulation affects the cleanliness of the oil and the treatment effect. Furthermore, there is a lack of effective online slag removal and oil circulation mechanisms.
[0004] More importantly, traditional equipment typically requires multiple independent power sources to achieve functions such as lifting, rotating, and oil agitation, resulting in complex structures, high energy consumption, and difficult maintenance. Improving the automation level, cleaning coverage, oil utilization rate, and operational reliability of equipment while ensuring cleaning and rust prevention quality has become a key technical challenge in the field of rust prevention treatment for automotive parts.
[0005] Therefore, there is an urgent need to develop a new type of rust prevention equipment that integrates batch clamping, multi-directional cleaning, automatic slag removal and oil circulation to solve the defects of existing technologies such as incomplete cleaning, single function and inconvenient maintenance. Summary of the Invention
[0006] The purpose of this invention is to provide a rust prevention treatment device for automotive parts to solve the above-mentioned defects caused by the prior art.
[0007] A rust-preventing treatment device for automotive parts includes an oil washing mechanism and a clamping mechanism. The oil washing mechanism includes an oil washing tank, a hydraulic cylinder, a motor, a rotating frame, and a pulsator. Multiple clamping mechanisms are provided and evenly distributed circumferentially on the rotating frame. Each clamping mechanism includes a hydraulic cylinder, a clamping plate, and a support bar. The hydraulic cylinder drives the clamping plate to move, clamping and fixing multiple brake wheel cylinder bodies between the clamping plate and the support bar. The hydraulic cylinder drives the rotating frame to rise and fall, completely immersing the clamped brake wheel cylinder bodies in the rust-preventing oil in the oil washing tank. The motor drives the rotating frame to rotate, causing the brake wheel cylinder bodies to move in the oil, thus rinsing their internal oil chambers. The motor also drives the pulsator to rotate through a transmission structure, agitating the oil in the oil washing tank upwards, thus rinsing their surfaces and threaded holes.
[0008] Preferably, a pair of hydraulic cylinders are mounted above the oil washing tank via a U-shaped fixing frame, with their piston rods extending vertically downwards. The motor is connected to the end of the piston rod of the pair of hydraulic cylinders via a lifting plate. A rotating shaft is vertically provided at the center of the rotating frame, and the upper end of the rotating shaft is coaxially connected to the output shaft of the motor.
[0009] Preferably, the lower end of the rotating shaft is connected to a friction disc one via a one-way bearing, the bottom center of the oil washing tank is rotatably connected to a rotating tube via a sealed bearing, the impeller is coaxially fixed on the rotating tube, and the upper end of the rotating tube is fixedly connected to a friction disc two, the lower end face of the friction disc one and the upper end face of the friction disc two are in contact to form a friction transmission engagement.
[0010] Preferably, the second hydraulic cylinder is connected to the rotating frame via a fixed plate, and its piston rod extends horizontally outward. The end of the piston rod is connected to a hinge seat, and an L-shaped hinge bar is hinged to the first hinge seat. A second hinge seat is provided on the outer side of the fixed plate, and a second hinge bar is hinged to the second hinge seat. The other end of the second hinge bar is hinged to the other end of the first hinge bar. The clamping plate is fixedly connected to the side of the first hinge bar, and clamping grooves that match the shape of the brake wheel cylinder body are provided on both sides. A pair of support bars are provided and connected in parallel to the lower part of the fixed plate.
[0011] Preferably, the sidewall of the rotating tube is provided with a plurality of suction ports, which are located at or slightly above the bottom of the oil washing tank, and the lower end of the rotating tube is connected to a hand valve.
[0012] Preferably, a C-shaped rubber pad is adhered to the inner wall of the clamping groove.
[0013] Preferably, a vibration motor is fixedly connected to the top surface of the clamping plate.
[0014] Compared with the prior art, the present invention has the following advantages: 1. The rotating frame driven by the electric motor moves the workpiece "swimming" in the oil, realizing dynamic flushing of the inner cavity of the brake wheel cylinder; at the same time, the impeller agitates the oil to form an upward flow, effectively flushing the workpiece surface and complex structures such as threaded holes, ensuring that the rust-preventive oil fully penetrates, and cleaning and protection are thorough.
[0015] 2. The linkage clamping mechanism is adopted, and the clamping force is uniform and adjustable; the clamping groove is equipped with a C-shaped rubber pad, which can not only buffer the clamping stress and prevent the workpiece surface from being scratched, but also enhance the friction and ensure that the workpiece does not loosen during violent swinging.
[0016] 3. The rotating pipe has a suction port on its side wall and a hand valve at the bottom. After cleaning, impurities such as iron filings deposited at the bottom of the tank can be discharged with the oil. After external filtration, the oil can be reinjected to achieve recycling, extend service life, and reduce environmental pollution.
[0017] 4. By cleverly combining a one-way bearing with a friction drive structure, the same motor drives the impeller to stir oil and clean the surface when rotating clockwise, and only drives the workpiece to move and clean the inner cavity when rotating counterclockwise, realizing "one motor, two functions", reducing the number of power units and lowering energy consumption and equipment costs.
[0018] In summary, this invention not only solves the problems of incomplete cleaning, limited functionality, and easy oil contamination in traditional rust prevention equipment, but also achieves efficient, energy-saving, and environmentally friendly automated rust prevention through innovative mechanical structure design, demonstrating promising industrial application prospects and promotional value.

Detailed Implementation
[0029] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.
[0030] like Figures 1 to 9 As shown, a rust prevention treatment device for automotive parts includes an oil washing mechanism 10 and a clamping mechanism 20. The oil washing mechanism 10 includes an oil washing tank 101, a hydraulic cylinder 103, a motor 105, a rotating frame 107, and a pulsator 112. Multiple clamping mechanisms 20 are provided and evenly distributed circumferentially on the rotating frame 107. Each clamping mechanism 20 includes a hydraulic cylinder 202, a clamping plate 207, and a support bar 209. The hydraulic cylinder 202 drives the clamping plate 207 to move, clamping multiple brake wheel cylinder bodies 30. The hydraulic cylinder 103 drives the rotating frame 107 to rise and fall, which is tightly fixed between the clamping plate 207 and the support bar 209, so as to completely immerse the clamped brake wheel cylinder body 30 in the rust-preventive oil in the oil washing tank 101. The electric motor 105 drives the rotating frame 107 to rotate, which causes the brake wheel cylinder body 30 to move in the oil, thereby rinsing its internal oil cavity. The electric motor 105 also drives the impeller 112 to rotate through the transmission structure, which stirs the oil in the oil washing tank 101 upward, thereby rinsing its surface and threaded holes.
[0031] In this embodiment, a pair of hydraulic cylinders 103 are mounted above the oil washing tank 101 via a U-shaped fixing frame 102, with their piston rods extending vertically downwards. The electric motor 105 is connected to the end of the piston rods of the hydraulic cylinders 103 via a lifting plate 104. A rotating shaft 106 is vertically positioned at the center of the rotating frame 107, and the upper end of the rotating shaft 106 is coaxially connected to the output shaft of the electric motor 105. The hydraulic cylinders 103 drive the rotating frame 107 to rise and fall, while the electric motor 105 drives the rotating frame 107 to move.
[0032] In this embodiment, the lower end of the rotating shaft 106 is connected to a friction disc 109 via a one-way bearing 108. The bottom center of the oil washing tank 101 is rotatably connected to a rotating tube 111 via a sealed bearing 110. The impeller 112 is coaxially fixed to the rotating tube 111. A second friction disc 113 is fixedly connected to the upper end of the rotating tube 111. The lower end face of the first friction disc 109 contacts the upper end face of the second friction disc 113 to form a friction transmission engagement. The motor 105 drives the impeller 112 to rotate through the friction transmission structure composed of the first friction disc 109 and the second friction disc 113, thus agitating the oil in the oil washing tank 101 upwards.
[0033] In this embodiment, the second hydraulic cylinder 202 is connected to the rotating frame 107 via a fixing plate 201. Its piston rod extends horizontally outward, and the end of the piston rod is connected to a hinge seat 203. The hinge seat 203 is hinged to an L-shaped hinge bar 204. The outer side of the fixing plate 201 is provided with a second hinge seat 205, and the second hinge seat 205 is hinged to a second hinge bar 206. The other end of the second hinge bar 206 is hinged to the other end of the first hinge bar 204. The clamping plate 207 is fixedly connected to the side of the first hinge bar 204, and its two sides are provided with clamping grooves 207a that match the shape of the brake wheel cylinder body 30. The support bar 209 is provided in pairs and is connected in parallel to the lower part of the fixing plate 201. The piston rod of hydraulic cylinder 202 extends and drives hinge bar 204 and clamping plate 207 to deflect downward, clamping and fixing multiple brake wheel cylinder bodies 30 between clamping plate 207 and support bar 209. The piston rod of hydraulic cylinder 202 retracts and drives hinge bar 204 and clamping plate 207 to deflect upward, releasing the clamped multiple brake wheel cylinder bodies 30.
[0034] In this embodiment, the rotating tube 111 has multiple suction ports 111a evenly distributed on its sidewall. The suction ports 111a are located at or slightly above the bottom of the oil washing tank 101. A hand valve 114 is connected to the lower end of the rotating tube 111. After opening the hand valve 114, iron filings and other debris at the bottom of the oil washing tank 101 can be discharged through the suction ports 111a, filtered, and then reinjected into the oil washing tank 101.
[0035] In this embodiment, a C-shaped rubber pad 208 is bonded to the inner wall of the clamping groove 207a. The rubber pad 208 is used to buffer clamping stress, prevent scratches on the workpiece surface, and enhance clamping friction.
[0036] In this embodiment, a vibration motor 210 is fixedly connected to the top surface of the clamping plate 207. The vibration motor 210 is used to apply micro-vibration during the oil washing process to promote the oil to enter the hard-to-clean areas such as the inner cavity and threaded holes of the workpiece, thereby improving the uniformity of cleaning and rust prevention. In addition, the vibration motor 210 is also used to apply micro-vibration after oil washing to promote the excess oil to drip into the oil washing tank 101.
[0037] The working principle of a rust prevention treatment device for automotive parts: S1: Multiple brake wheel cylinder bodies 30 are placed inverted between a pair of support bars 209 of clamping mechanism 20 at intervals. Then, the piston rod of hydraulic cylinder 202 extends and drives the linkage mechanism formed by hinge bar 1 204 and hinge bar 206 to move, causing clamping plate 207 to deflect downward and clamp each brake wheel cylinder body 30 between clamping plate 207 and support bar 209. S2: Hydraulic cylinder 103 drives the rotating frame 107 to descend, completely immersing the clamped brake wheel cylinder body 30 in the rust-preventive oil in the oil washing tank 101, and the lower end face of friction disc 109 contacts the upper end face of friction disc 2 113. S3: The electric motor 105 drives the rotating frame 107 to rotate clockwise, which in turn drives the brake wheel cylinder body 30 to move clockwise in the oil, thus rinsing its internal oil chamber. At this time, the one-way bearing 108 at the lower end of the rotating shaft 106 is locked. The impeller 112 can be driven to rotate through the friction transmission structure composed of friction disc 109 and friction disc 113. The impeller 112 stirs the oil in the oil washing tank 101 upward, forming a strong liquid flow, thus rinsing the surface of the workpiece and the threaded hole. S4: The electric motor 105 drives the rotating frame 107 to rotate counterclockwise, which in turn drives the brake wheel cylinder body 30 to move counterclockwise in the oil, thus rinsing its internal oil chamber. At this time, the one-way bearing 108 at the lower end of the rotating shaft 106 is in a free rotation state and cannot drive the impeller 112 to rotate through the friction transmission structure composed of friction disc one 109 and friction disc two 113. The iron filings and other debris washed off gradually settle at the bottom of the oil washing tank due to gravity. S5: Hydraulic cylinder 103 drives the rotating frame 107 to rise, completely separating the cleaned brake wheel cylinder body 30 from the anti-rust oil in the oil washing tank 101. S6: The piston rod of hydraulic cylinder 202 retracts, driving the linkage mechanism formed by hinge bar 1 204 and hinge bar 206 to move, causing clamping plate 207 to deflect upward and remove the cleaned brake wheel cylinder body 30. S7: Open the hand valve 114 at the lower end of the rotary tube 111. The oil carrying iron filings and other debris at the bottom of the oil washing tank 101 is discharged through the suction port 111a. After filtration, it is reinjected back into the oil washing tank 101.
[0038] Therefore, the disclosed embodiments described above are merely illustrative in all respects and are not exhaustive. All modifications within the scope of this invention or its equivalents are included in this invention.
