Description

Technical Field

[0001] This utility model relates to the field of automotive parts manufacturing technology, and in particular to a cleaning device for steering knuckles after processing. Background Technology

[0002] As a key component of a vehicle, the manufacturing quality of the steering knuckle directly affects the vehicle's safety and handling performance. In actual production, the surface of the machined steering knuckle often has residual impurities such as oil stains and metal shavings. If not thoroughly cleaned, these impurities will seriously affect the assembly accuracy, service life, and overall performance of the vehicle.

[0003] Currently, the main methods for cleaning steering knuckles include manual cleaning and traditional mechanical cleaning. Manual cleaning relies on people using brushes and cleaning agents, which is not only extremely inefficient, but also highly dependent on the worker's skill level and work attitude, making it difficult to guarantee consistent cleaning quality. For some complex steering knuckles, manual cleaning is even more difficult to reach the tiny internal gaps and holes, resulting in incomplete cleaning. While traditional mechanical cleaning methods improve cleaning efficiency to some extent, such as common spray cleaning equipment, the limitations of the spray angle and force cannot ensure that the cleaning fluid evenly covers all surfaces of the steering knuckle, especially some dents and corners, which are prone to becoming cleaning dead spots. Although soaking cleaning allows the steering knuckle to fully contact the cleaning fluid, simple soaking is not enough to effectively remove stubborn oil stains and tightly attached debris. Utility Model Content

[0004] The purpose of this invention is to provide a cleaning device for steering knuckles after processing, which can effectively solve the problems in the background art.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0006] A steering knuckle post-processing cleaning device includes a control box, a cleaning tank fixedly installed inside the control box, a cylinder fixedly installed on the rear side of the control box, and the cylinder connected to an air pump inside the control box via an air pipe. First guide rails are also fixedly installed on both sides of the control box, and first sliders are slidably connected to the first guide rails. A fixing plate is fixedly installed on the rear side of the first slider, and a top rod is fixedly installed on the fixing plate near the first slider. A top plate is fixedly connected to the two top rods, and a connecting plate is movably connected to the lower end of the top plate near the top rods. Two hanging rods are fixedly connected to the lower end of the connecting plate, and an upper basket and a lower basket are fixedly connected to the lower ends of the two hanging rods. Multiple connecting rods are also fixedly connected between the upper basket and the lower basket. Multiple guide seats are also fixedly installed on the control box located behind the hanging rods.

[0007] As a further preferred embodiment of this utility model, one end of the piston rod of the cylinder is fixedly connected to the top plate. With the help of the thrust of the cylinder, the lifting and lowering functions of the lower basket and the connecting rod can be realized in conjunction with the top rod, the top plate, the connecting plate, and the hanging rod.

[0008] As a further preferred embodiment of this utility model, a second guide rail is fixedly installed at the lower end of the top plate.

[0009] As a further preferred embodiment of this utility model, two second sliders are fixedly installed on the upper end of the connecting plate, the second sliders are slidably connected to the second guide rail, and guide grooves are respectively opened on the rear side of the two lifting rods.

[0010] As a further preferred embodiment of this utility model, the guide seat is rotatably mounted with a bearing on one side relative to the boom, and the bearing is also rolledly connected in the guide groove. The two booms are slidably connected to the second guide rail via the connecting plate and the second slider. With the help of the guide seat, the bearing and the guide groove, when the boom drives the lower basket and the connecting rod to rise and fall, the lower basket and the connecting rod will make a rapid reciprocating swing in the cylinder, thereby shaking off the debris deposited on the steering knuckle and improving the cleaning effect of the steering knuckle.

[0011] As a further preferred embodiment of this utility model, the lower basket is a hollow structure, and multiple air distribution pipes are fixedly connected to the inner side of the lower basket and communicate with the inner cavity of the lower basket. The lower basket is connected to the air pump in the control box through air pipes, and multiple guide wheels are rotatably installed on the outer side of the lower basket.

[0012] As a further preferred embodiment of this utility model, rubber pads are movably installed on the lower basket and the air distribution pipe. The finished steering knuckle is placed on the rubber pads, and then it can be put into the cylinder for cleaning in conjunction with the cylinder, push rod, top plate, connecting plate, lower basket, and upper basket. Bubbles are generated through the air distribution pipe to improve the cleaning effect.

[0013] As a further preferred embodiment of this utility model, a protective cover is also fixedly installed on the rear side of the control box, and the cross-section of the protective cover is C-shaped.

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] In this invention, by using a cylinder, a first guide rail, a top rod, a top plate, a connecting plate, and a hanging rod, the steering knuckle placed in the upper and lower baskets can be immersed in the cleaning fluid in the cylinder. A large number of air bubbles are injected into the cleaning fluid in the cylinder through multiple air distribution pipes in the lower basket, thereby improving the cleaning effect of the steering knuckle. At the same time, when the hanging rod moves the upper and lower baskets to move the cleaned steering knuckle upwards, the bearings and guide grooves enable the upper and lower baskets to swing rapidly, thereby preventing some debris from settling on the steering knuckle.

[0024] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0025] like Figures 1-7As shown, the present invention provides a steering knuckle post-processing cleaning device, including a control box 1, a cleaning tank 2 fixedly installed inside the control box 1, a cylinder 3 fixedly installed on the rear side of the control box 1, and the cylinder 3 connected to an air pump inside the control box 1 through an air pipe. A first guide rail 4 is also fixedly installed on both sides of the control box 1, a first slider 5 is slidably connected to the first guide rail 4, a fixing plate 6 is fixedly installed on the rear side of the first slider 5, a top rod 7 is fixedly installed on the fixing plate 6 near the first slider 5, a top plate 8 is fixedly connected to the two top rods 7, a connecting plate 10 is movably connected to the lower end of the top plate 8 near the top rod 7, two hanging rods 11 are fixedly connected to the lower end of the connecting plate 10, an upper basket 12 and a lower basket 13 are fixedly connected to the lower end of the two hanging rods 11, and multiple connecting rods 14 are fixedly connected between the upper basket 12 and the lower basket 13. Multiple guide seats 16 are also fixedly installed on the control box 1 located behind the hanging rods 11.

[0026] like Figures 1-2 , Figures 5-7 As shown, one end of the piston rod of cylinder 3 is fixedly connected to the top plate 8. With the thrust of cylinder 3, it can work with top rod 7, top plate 8, connecting plate 10, and hanging rod 11 to realize the lifting and lowering function of lower basket 13 and connecting rod 14. A second guide rail 18 is fixedly installed at the lower end of top plate 8, and two second sliders 19 are fixedly installed at the upper end of connecting plate 10. The second sliders 19 are slidably connected to the second guide rail 18. Guide grooves 20 are respectively opened on the rear side of the two hanging rods 11, and the guide seat 16 is located on one side of the hanging rod 11. The bearing 21 is rotatably mounted and is also rolledly connected in the guide groove 20. The two rods 11 are slidably connected to the second slider 19 on the second guide rail 18 through the connecting plate 10. With the help of the guide seat 16, the bearing 21 and the guide groove 20, when the rods 11 drive the lower basket 13 and the connecting rod 14 to rise and fall, the lower basket 13 and the connecting rod 14 will make a rapid reciprocating swing in the cylinder 3, thereby shaking off the debris deposited on the steering knuckle and improving the cleaning effect of the steering knuckle.

[0027] like Figure 1 , Figures 3-7 As shown, the lower basket 13 is a hollow structure. Multiple air distribution pipes 15 are fixedly connected to the inner side of the lower basket 13 and communicate with the inner cavity of the lower basket 13. The lower basket 13 is connected to the air pump in the control box 1 through the air pipes. Multiple guide wheels 22 are also rotatably installed on the outer side of the lower basket 13. Rubber pads 9 are movably installed on the lower basket 13 and the air distribution pipes 15. When the processed steering knuckle is placed on the rubber pad 9, it can be put into the cylinder 3 for cleaning in conjunction with the cylinder 3, the push rod 7, the top plate 8, the connecting plate 10, the lower basket 13, and the upper basket 12. Bubbles are generated through the air distribution pipes 15 to improve the cleaning effect. A protective cover 17 is also fixedly installed on the rear side of the control box 1, and the transverse cross section of the protective cover 17 is C-shaped.

[0028] It should be noted that this utility model is a steering knuckle cleaning device after processing. When cleaning a newly processed steering knuckle, the steering knuckle can be placed in the upper basket 12 and the lower basket 13, and supported by the air distribution pipe 15 and the rubber pad 9, which has a porous structure. Then, the cylinder 3 can be started through the control box 1, causing the piston rod of the cylinder 3 to gradually retract into the cylinder 3. This causes the piston rod of the cylinder 3 to pull the top plate 8 down, and the top plate 8 drives the two push rods 7 to move down. The two push rods 7 are respectively fixed by the lower end plate. 6 drives the first slider 5 to slide downwards on the corresponding first guide rail 4. At the same time, the top plate 8 also drives the connecting plate 10 and the hanging rod 11 to move downwards synchronously through the second guide rail 18 and the second slider 19. This causes the two hanging rods 11 to drive the upper basket 12 and the lower basket 13 to move downwards, and causes the upper basket 12 and the lower basket 13 to place the steering knuckle into the cleaning fluid in the cleaning tank 2. When the piston rod of the cylinder 3 retracts to a certain extent, the air pump in the control box 1 starts again and injects gas into the lower basket 13 and the air distribution pipe 15 through the tap and pipe, thereby causing the air distribution pipe 15 to move downwards. The gas inside is ejected through the vents on its inner wall, causing a large number of bubbles to form in the cleaning fluid in the cleaning tank 2. These bubbles agitate the cleaning fluid and remove the cutting fluid and debris adhering to the steering knuckle. After a single cleaning step of the steering knuckle is completed, the piston rod of the cylinder 3 moves the top plate 8 upward, which in turn moves the top plate 8 and the push rod 7 upward. Similarly, the top plate 8 moves the connecting plate 10 and the hanger rod 11 upward via the second guide rail 18 and the second slider 19. The guide groove 20 on the rear side of the hanger rod 11 slides on the bearing 21 on the front side of the guide seat 16, and the guide groove... The middle part of the 20 has a curved structure, so that when the upper basket 12 and the lower basket 13 drive the steering knuckle to move up from the cleaning tank 2 and back into the cleaning fluid in the cleaning tank 2, the two hanging rods 11, in conjunction with the guide groove 20 and the bearing 21, can swing back and forth. This causes the two hanging rods 11 to drive the upper connecting plate 10 to move back and forth. Then, the connecting plate 10 drives the two second sliders 19 to move back and forth on the second guide rail 18. Thus, after the upper basket 12 and the steering knuckle swing back and forth quickly in the cleaning tank 2, the debris remaining on the steering knuckle is shaken off.
