Description

Technical Field

[0001] The invention relates to the technical field of automobile leaf spring processing, in particular to a surface anti-rust treatment machine for automobile leaf spring processing. Background Art

[0002] Automobile leaf springs are an important component used in automobile suspension systems. They are made of spring steel plates and have the property of elastic deformation. These leaf springs are usually in torsion or compression form and carry the weight of the vehicle, providing support and buffering functions for the suspension system. The main function of automobile leaf springs is to absorb and reduce vibration and impact during vehicle driving, maintain vehicle body stability, and provide ride comfort. They are located in the suspension system of the car and usually work with suspension arms, shock absorbers and other suspension components to ensure the smooth driving of the vehicle on uneven roads.

[0003] Existing automotive leaf springs need to be treated with rust prevention during processing, and spraying or coating rust prevention paint is a common surface treatment method. Rust prevention paint can form a protective coating to block the corrosion of leaf springs caused by factors such as air and moisture. Common rust prevention paints include epoxy resin paints, polyurethane paints or other special paints for rust prevention.

[0004] In the prior art, the stacked leaf springs are placed in an oil immersion tank to complete the anti-rust oil coating on the surface of the leaf springs. During the operation, when a leaf spring with a large mass enters the oil immersion tank, when an object enters the anti-rust oil, a shock wave is generated. This is due to the energy transfer when the leaf spring moves quickly and comes into contact with the anti-rust oil. The shock wave will quickly spread into the anti-rust oil, causing back and forth vibrations to form ripples. The oscillating ripples will hit the inner wall of the oil immersion tank, thereby causing splashing.

[0005] Anti-rust oil contains chemicals, and when it splashes into the environment, it pollutes water sources and air quality. This has a negative impact on the ecosystem and environmental health. When there is anti-rust oil residue on the ground, workers will lose stability, leading to slip and fall accidents in the workplace, increasing the risk of injury. Since the existing oil immersion tank is just a simple container for holding anti-rust oil, its structure is relatively simple and lacks a structure to prevent anti-rust oil from splashing, it is impossible to shield and collect the splashed anti-rust oil when the spring steel plate is oil-immersed, resulting in waste of anti-rust oil and low utilization rate.

[0006] The existing steps of adding anti-rust oil to the oil immersion tank are performed independently. The anti-rust oil is continuously reduced during the oil immersion. When the anti-rust oil cannot meet the normal operation requirements, a certain amount of anti-rust oil needs to be manually added into the oil immersion tank. This makes it impossible to ensure the uniformity of the dosage of the anti-rust oil during each oil immersion, resulting in uneven lubrication of the leaf spring during oil immersion, with some areas being over-lubricated and other areas lacking sufficient lubrication, which affects the sliding performance and life of the spring and reduces the qualified rate of the leaf springs in the same batch.

[0007] Therefore, a surface antirust treatment machine for automobile leaf spring processing is proposed. Summary of the invention

[0022] 2.

[0023] 3.

At the same time, the oil immersion operation time of the leaf spring is increased and the number of manual additions of anti-rust oil is reduced. BRIEF DESCRIPTION OF THE DRAWINGS

[0038] The following will be combined with 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 of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0039] See also Figures 1 to 10 , is an embodiment provided by the present invention: a surface anti-rust treatment machine for automobile leaf spring processing, comprising an oil immersion pool 11, an outer wall of the oil immersion pool 11 is fixedly connected to an oil storage tank 12, an upper end surface of the oil storage tank 12 is provided with an oil inlet, and an anti-splash component for preventing anti-rust oil from splashing during oil immersion is provided on the oil immersion pool 11, wherein:

[0040] The anti-splash assembly includes a guide rod 21 and a crankshaft 29. The guide rod 21 is symmetrically slidably connected to the upper end of the oil immersion pool 11. The upper end surface of the guide rod 21 is fixedly connected to an extrusion plate 22. The outer walls of a pair of guide rods 21 are sleeved with a return spring 23. A pair of extrusion plates 22 are provided with a tooth groove 24 on the side away from the inside of the oil immersion pool 11. The outer wall of the oil immersion pool 11 is slidably connected to an anti-splash collecting plate 25. The inside of the anti-splash collecting plate 25 is set to an inclined surface oblique to the inside of the oil immersion pool 11. The two ends of the anti-splash collecting plate 25 are symmetrically fixedly connected with tooth plates 26. The guide rod 21 and the tooth plate 2 6 are meshed, a pair of tooth plates 26 are fixedly connected with rubber pads 28 at both ends, the outer wall of the oil storage tank 12 is symmetrically fixedly connected with limit rods 27, a pair of limit rods 27 penetrate the corresponding tooth plates 26, the limit rods 27 are slidably connected with the corresponding tooth plates 26, a pair of limit rods 27 are fitted with the inside of the tooth plates 26 on the corresponding side, a crankshaft 29 penetrates and is rotatably connected inside the oil immersion tank 11, and a driving gear 210 is fixedly connected at both ends of the crankshaft 29, the driving gear 210 is meshed with the tooth groove 24, and the crankshaft 29 is located on the rotation path of the driving gear 210;

[0041] Among them: the setting of the splash-proof collecting plate 25 plays a role in shielding and collecting the anti-rust oil splashing out of the oil immersion pool 11; the setting of a pair of limit rods 27 plays a role in providing stability during the up and down sliding of the splash-proof collecting plate 25, thereby preventing the splash-proof collecting plate 25 from deflecting and tipping over during the sliding process; the setting of the internal inclined surface of the splash-proof collecting plate 25 plays a role in quickly gathering the splashed anti-rust oil, thereby preventing the anti-rust oil from adhering to the inner wall of the splash-proof collecting plate 25 for a long time; the setting of a pair of rubber pads 28 plays a role in buffering when the tooth plate 26 slides up and down and fits with the two ends of the limit rod 27, thereby reducing the wear between the limit rod 27 and the corresponding tooth plate 26.

[0042] Better: An inclined surface is set at the bottom end of the splash-proof collecting plate 25, which is inclined with respect to the pair of connecting pipes 38. The inclined surface has a guiding function, which is conducive to the anti-rust oil inside the splash-proof collecting plate 25 to quickly gather at the ports of the pair of connecting pipes 38 and flow into the oil immersion pool 11 through the pair of connecting pipes 38. The limit rod 27 and the tooth plate 26 are set to metal material. The metal material usually has a smooth surface and a lower friction coefficient, which means that when the tooth plate 26 slides on the surface of the limit rod 27, the friction between them is small, which allows the tooth plate 26 to slide more easily inside the limit rod 27 without being subject to excessive resistance.

[0043] The oil storage tank 12 is provided with a feeding assembly for automatically adding rust-proof oil to the oil immersion pool 11, wherein:

[0044] The feeding assembly includes a bearing block 31 and a push rod 36. The bearing block 31 is symmetrically fixedly connected to the inside of the oil storage tank 12. A pair of bearing blocks 31 are fixedly connected to a lifting cylinder 32 at one end away from the inside of the oil immersion pool 11. A pair of lifting cylinders 32 are slidably connected to a movable one-way valve 33. The upper end surface of the movable one-way valve 33 is fixedly connected to a connecting rod 35. The bottom end of the pair of lifting cylinders 32 is fixedly connected to a fixed one-way valve 34. The push rod 36 is symmetrically fixedly sleeved on the outer wall of the crankshaft 29. The push rod 36 is rotatably connected to the end close to the corresponding connecting rod 35. The outer wall of the pair of lifting cylinders 32 is close to the oil immersion pool 11. One side is fixedly connected with an oil storage pipe 37, a pair of oil storage pipes 37 are fixedly connected to the outer wall of the oil immersion pool 11, the lower end of the splash-proof collecting plate 25 is symmetrically fixedly connected with a connecting pipe 38, one end of a pair of connecting pipes 38 away from the splash-proof collecting plate 25 is fixedly connected to the outer wall of the oil storage tank 12, the lifting cylinder 32 is connected with the oil storage pipe 37, the oil storage pipe 37 is connected to the inside of the oil immersion pool 11, the oil storage tank 37 is arranged to be inclined toward the inside of the oil immersion pool 11, a pair of sealing plates 39 are fixedly connected to the inner side of the extrusion plate 22, the connecting pipe 38 is connected to the inside of the splash-proof collecting plate 25, and the connecting pipe 38 is connected to the inside of the oil storage tank 12;

[0045] Among them: a pair of lifting cylinders 32 leave a gap with the bottom end of the oil storage tank 12, which is convenient for the inside of the oil storage tank 12 to enter the lifting cylinder 32. The setting of the movable one-way valve 33 and the fixed one-way valve 34 plays a role in controlling the internal air pressure of the lifting cylinder 32. By controlling the internal air pressure of the lifting cylinder 32, the anti-rust oil inside the oil storage tank 12 has been pumped to the upper position inside the lifting cylinder 32 and flows into the oil immersion pool 11 through the oil storage pipe 37. The setting of the push rod 36 drives the corresponding movable one-way valve 33 to slide back and forth up and down inside the lifting cylinder 32 when it moves. The setting of the oil storage pipe 37 facilitates the anti-rust oil inside the oil storage tank 12 to enter the oil immersion pool 11, and also has the function of storing oil.

[0046] The above implementation works as follows:

[0047] The initialization steps are as follows:

[0048] The operator pours anti-rust oil into the oil immersion pool 11 and the oil storage tank 12. The anti-rust oil level inside the oil immersion pool 11 is lower than the port of the side connecting pipe 38, and the anti-rust oil level inside the oil storage tank 12 is lower than the upper end surface of a pair of lifting cylinders 32. The operator stacks the leaf springs on the collecting rack and then moves the collecting rack to a position above the oil immersion pool 11.

[0049] The working steps are as follows:

[0050] The following is the operation prospect of the anti-splash component: a large-mass leaf spring enters the oil-immersed tank 11. When an object enters the anti-rust oil, a shock wave will be generated. This is due to the energy transfer when the leaf spring moves quickly and contacts the anti-rust oil. The shock wave will quickly spread into the anti-rust oil, causing back and forth vibrations to form ripples. The oscillating ripples will hit the inner wall of the oil-immersed tank 11, thereby generating a splash phenomenon;

[0051] The anti-splash component blocks and collects the splashing anti-rust oil;

[0052] like Figures 1 to 5As shown, when the operator lowers the collecting rack position through the lifting device, the bottom end of the collecting rack begins to conflict with one end of a pair of squeezing plates 22, and then drives the pair of squeezing plates 22 to slide into the oil immersion pool 11 together. During the sliding process of the squeezing plates 22, the squeezing plates 22 slide synchronously into the oil immersion pool 11 through the corresponding guide rods 21. At this time, the return spring 23 is elastically compressed, and the squeezing plates 22 that continue to slide downward drive the tooth grooves 24 away from the inside of the oil immersion pool 11 to mesh with the corresponding driving gear 210, and begin to drive the corresponding driving gear 210 to rotate. Through the rotation of the driving gear 210, the driving gear 210 drives the corresponding meshing tooth plate 26 on the other side to slide in the opposite direction of the moving direction of the squeezing plates 22. The pair of tooth plates 26 simultaneously drive the splash-proof collecting plate 25 to move toward the upper end of the oil immersion pool 11. During the sliding process, the interiors of the pair of tooth plates 26 are in contact with the corresponding limit rods 27, so that the tooth plates 26 can be stable in the process of driving the splash-proof collecting plate 25 to slide upward;

[0053] When the collecting rack drives a pair of extrusion plates 22 to slide to the bottom end of the oil immersion pool 11, the pair of extrusion plates 22 stop sliding immediately, thereby stopping the meshing driving gear 210 from rotating. At this time, the driving gear 210 and the corresponding tooth plate 26 are in static stability, and the limit rod 27 is located at the bottom end of the corresponding tooth plate 26. The pair of tooth plates 26 drive the upper end of the splash-proof collecting plate 25 to rise to the highest point, and the splashing anti-rust oil will be blocked by the splash-proof collecting plate 25. Since the inner wall of the splash-proof collecting plate 25 is inclined to the oil immersion pool 11, under the action of gravity, the blocked rust-proof oil is guided to the bottom of the splash-proof collecting plate 25 and collected at the bottom end of the splash-proof collecting plate 25. When the oil immersion of the leaf spring is finished, the operator lifts the collecting rack through the lifting device. At this time, a pair of return springs 23 begin to elastically extend and push the corresponding extrusion plates 22 to move away from the inside of the oil immersion pool 11. The pair of extrusion plates 22 are driven by the return springs 23 The corresponding driving gear 210 rotates in the opposite direction, so that a pair of toothed plates 26 drives the splash-proof collecting plate 25 to move downward. When the reset spring 23 is disengaged from the corresponding driving gear 210, the toothed plate 26 drives the splash-proof collecting plate 25 to restore its position. At this time, the limit rod 27 is located at the uppermost end inside the corresponding toothed plate 26, and the pair of reset springs 23 continue to extend, thereby driving the corresponding extrusion plate 22 to continue to rise until it is reset. The self-weight of the leaf spring and the elastic extension of the pair of reset springs 23 are used to indirectly drive the splash-proof collecting plate 25 to rise and fall, respectively, to prevent the anti-rust oil from splashing out of the oil immersion pool 11 when the leaf spring is immersed in oil, thereby ensuring the working environment of the staff. At the same time, the splash-proof collecting plate 25 will also collect the splashed anti-rust oil, thereby improving the utilization rate of the anti-rust oil and thus reducing the raw material cost. At the same time, the splash-proof collecting plate 25 descends, which is convenient for the staff to observe the oil immersion effect of the leaf spring after the oil immersion is completed, thereby improving the oil immersion anti-rust treatment effect.

[0054] The following is the operation prospect of the feeding assembly: as the leaf spring is immersed in oil, the amount of anti-rust oil in the oil immersion pool 11 will be reduced, and the reduced anti-rust oil will cause the subsequent leaf spring to have a different oil immersion dosage from the previous one, thus resulting in different oil immersion effects;

[0055] The feeding assembly intermittently transfers the anti-rust oil in the oil storage tank 12 to the inside of the oil immersion tank 11;

[0056] like Figures 6 to 10 As shown, as the pair of extrusion plates 22 continue to slide downward, the pair of extrusion plates 22 drive the sealing plate 39 to move to the port connecting the oil storage pipe 37 and the inside of the oil immersion tank 11 and seal it. When the tooth groove 24 is meshed with the corresponding driving gear 210, the driving gear 210 simultaneously drives the fixedly connected crankshaft 29 to rotate. During the rotation of the crankshaft 29, the corresponding connecting rod 35 is driven to slide back and forth up and down inside the lifting cylinder 32 through a pair of push rods 36. Since the connecting rod 35 and the movable one-way valve 33 are fixedly connected, the corresponding connecting rod 35 is driven to slide synchronously when the connecting rod 35 slides back and forth up and down.

[0057] According to the attraction between molecules inside the liquid, which is called surface tension, when the liquid is at rest, the interaction between the molecules will keep it in a certain shape and position. When there is a difference in pressure (for example, one side of the liquid has a higher pressure and the other side has a lower pressure), this difference will affect the balance of forces between the liquid molecules, which will cause the liquid molecules in the low-pressure area to be more inclined to move and arrange to reduce the pressure difference, and then be pushed to the low-pressure area. This process is called "liquid flow";

[0058] When the connecting rod 35 drives the corresponding movable one-way valve 33 to rise in the corresponding internal position of the lifting cylinder 32, a low-pressure area will be formed in the lifting cylinder 32. Since the opening directions of the movable one-way valve 33 and the fixed one-way valve 34 are both limited to rotating toward the top of the lifting cylinder 32, the movable one-way valve 33 cannot be opened. As the movable one-way valve 33 continues to move upward, the pressure inside the lifting cylinder 32 will continue to decrease, causing the fixed one-way valve 34 to be opened, and the anti-rust oil inside the oil storage tank 12 will be sucked into the lifting cylinder 32. When the pressure inside the lifting cylinder 32 is restored to balance due to the suction of the anti-rust oil, the fixed one-way valve 34 will immediately close, causing the position The rust-proof oil inside the lifting cylinder 32 cannot flow out. When the connecting rod 35 drives the corresponding movable one-way valve 33 to descend in the corresponding position inside the lifting cylinder 32, a high-pressure area will be formed inside the lifting cylinder 32. As the movable one-way valve 33 continues to move downward, the pressure inside the lifting cylinder 32 will continue to increase, causing the movable one-way valve 33 to be opened. As the pressure inside the lifting cylinder 32 is restored, the movable one-way valve 33 is closed. When the connecting rod 35 drives the corresponding movable one-way valve 33 to rise again, the fixed one-way valve 34 will be opened again. This cycle is repeated to pump the rust-proof oil into the lifting cylinder 32 and into the oil storage pipe 37, realizing automatic pumping operation.

[0059] When a pair of extrusion plates 22 begin to reset under the thrust of the corresponding reset springs 23, when a pair of driving gears 210 disengage from the corresponding tooth grooves 24, the driving gear 210 drives the crankshaft 29 to stop rotating, thereby stopping the pumping operation, and the pair of extrusion plates 22 drives the sealing plate 39 to disengage from one end of the oil storage pipe 37, and the rust-proof oil stored in the oil storage pipe 37 will flow into the oil immersion tank 11 along the inclined wall inside the oil storage pipe 37, completing the automatic filling of the rust-proof oil inside the oil immersion tank 11, and the splashing rust-proof oil will be collected by the splash-proof collecting plate 25 and flow into the oil storage tank 12 through a pair of connecting pipes 38, completing the recycling of the rust-proof oil, and through the rotation of the crankshaft 29, the rust-proof oil is automatically filled into the oil storage pipe 37, and automatically flows into the oil immersion tank 11 when the leaf spring is taken out after oil immersion, reducing the number of times the operator manually adds rust-proof oil, thereby reducing the work intensity, ensuring the dosage of rust-proof oil inside the oil immersion tank 11, and improving the qualified rate of rust-proof processing of leaf springs.
