Description

Technical Field

[0001] This utility model belongs to the field of steel leaf spring seat processing technology, and particularly relates to a surface treatment structure for rust-proof steel leaf spring seats. Background Technology

[0002] Leaf spring seats are an important component of automotive suspension systems, primarily used to support and secure leaf springs, ensuring their stable operation during vehicle movement. After manufacturing, leaf spring seats are typically coated with an anti-rust paint using spraying equipment to enhance their corrosion resistance.

[0003] However, when existing spraying equipment is used to prevent rust on steel leaf spring seats, the sprayed paint inevitably drips onto the bottom of the device. After a period of time, it solidifies and forms hard impurities. To prevent the impurities from accumulating and becoming thicker, workers need to clean them regularly with tools. This process is not only physically demanding but also time-consuming.

[0004] Therefore, it is necessary to provide a surface treatment structure for rust-resistant steel plate spring seats to solve the above problems. Utility Model Content

[0005] To address the technical problem that existing spraying equipment used for rust prevention treatment of leaf spring seats requires manual removal of paint impurities at the bottom of the device, increasing labor intensity and time consumption, this utility model provides a surface treatment structure for rust prevention of leaf spring seats.

[0006] This utility model is implemented as follows: a surface treatment structure for a rust-proof steel leaf spring seat includes: a housing, an electric slide rail fixedly installed on the top inner wall of the housing, a connecting rod fixedly installed on the sliding block of the electric slide rail, a diverter pipe fixedly installed on the connecting rod, and a spray nozzle for rust prevention treatment of the steel leaf spring seat surface provided on the diverter pipe; a placement rack rotatably mounted on the housing via a rotating shaft, a cylinder fixedly installed on the placement rack, an electric push rod fixedly installed on the inner wall of the cylinder, and a clamp for fixing the steel leaf spring seat fixedly installed on the output rod of the electric push rod; and a cleaning mechanism assembled on the housing for scraping impurities from the bottom of the housing.

[0008] Preferably, the surface treatment structure for the rust-proof steel leaf spring seat further includes a rotating mechanism mounted on the housing for rotating the steel leaf spring seat.

[0009] Preferably, the rotating mechanism includes: a dual-axis motor fixedly installed on the top of the housing, the output shaft of the dual-axis motor being connected to a rotating rod via a second coupling, one end of the rotating rod being fixedly installed with a first sprocket; a second sprocket fixedly installed on the rotating shaft; and a chain sleeved on the first sprocket and the second sprocket.

[0010] Preferably, a protective shell is fixedly installed on the outer wall of the housing, and the protective shell is used to cover the first sprocket, the second sprocket and the chain.

[0011] Preferably, a limiting rod is fixedly installed on the placement rack, the limiting rod is slidably connected to the clamping plate, and the bottom of the box is provided with a discharge port for discharging impurities.

[0015] Compared with related technologies, the surface treatment structure for the rust-resistant steel plate spring seat provided by this utility model has the following beneficial effects:

[0016] This solution utilizes an electric push rod to move the clamping plate, firmly fixing the leaf spring seat to be treated for rust prevention onto the placement frame. An electric slide rail allows the connecting rod to move the distribution pipe and spray head, enabling the spray head to evenly spray the surface of the leaf spring seat, thus achieving rust prevention. During the spraying process, paint dripping to the bottom of the housing will solidify into impurities over time. After spraying, if cleaning is required, a cleaning mechanism can be activated. This mechanism removes the solidified impurities through mechanical scraping, and the cleaned impurities are discharged from the center of the bottom of the housing, keeping the bottom clean. This solution solves the technical problem of existing spraying equipment for rust prevention of leaf spring seats, where paint impurities at the bottom of the device require manual handling, increasing labor intensity and time consumption.

The terms "first," "second," etc., in the specification or the foregoing drawings of this application are used to distinguish different objects, not to describe a particular order.

[0023] In this document, the term "embodiment" means that a particular feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of this application. The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment mutually exclusive with other embodiments. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.

[0024] This utility model embodiment provides a surface treatment structure for a rust-resistant steel plate spring seat, such as... Figure 1-4 As shown, the surface treatment structure for the rust-proof steel leaf spring seat includes: a housing 1, an electric slide rail 2 fixedly installed on the top inner wall of the housing 1, a connecting rod 3 fixedly installed on the sliding block of the electric slide rail 2, a diversion pipe 4 fixedly installed on the connecting rod 3, and a spray nozzle for rust prevention treatment of the steel leaf spring seat surface provided on the diversion pipe 4; a placement rack 6 rotatably mounted on the housing 1 via a rotating shaft 5, a cylinder 7 fixedly installed on the placement rack 6, an electric push rod 8 fixedly installed on the inner wall of the cylinder 7, and a clamping plate 9 for fixing the steel leaf spring seat fixedly installed on the output rod of the electric push rod 8; and a cleaning mechanism assembled on the housing 1 for scraping impurities from the bottom of the housing 1.

[0025] In this solution, the leaf spring seat to be treated for rust prevention is placed on the two side racks 6. Then, the electric push rod 8 is activated to move the clamping plate 9, so that the clamping plate 9 can firmly fix the leaf spring seat on the rack 6. After fixing, the anti-rust coating is transported to the diversion pipe 4 through the corresponding equipment. At the same time, the electric slide rail 2 is activated to move the connecting rod 3 and the diversion pipe 4, so that the spray head can evenly spray the surface of the leaf spring seat, thereby achieving the anti-rust treatment of the leaf spring seat. During the spraying process, the coating dripped to the bottom of the box 1 will form solid impurities after a period of time. If it is necessary to clean these impurities after the spraying operation is completed, the cleaning mechanism can be activated. The cleaning mechanism can remove the solidified impurities by mechanical scraping. The cleaned impurities will be discharged from the center of the bottom of the box 1 to keep the bottom of the box 1 clean.

[0026] In a further preferred embodiment of this utility model, the cleaning mechanism includes: a housing 10 fixedly mounted on the box 1, with a screw 11 rotatably mounted on the housing 10; a servo motor 12 fixedly mounted on one side of the housing 10, the output shaft of the servo motor 12 being connected to the screw 11 via a first coupling; a threaded sleeve 13 threadedly mounted on the screw 11, with a first rectangular shell 14 fixedly mounted on the threaded sleeve 13, a second rectangular shell 15 slidably mounted on the first rectangular shell 14, a scraper 17 fixedly mounted on the bottom of the second rectangular shell 15, the scraper 17 contacting the bottom inner wall of the box 1; and a spring 16 fixedly mounted on the bottom inner wall of the second rectangular shell 15, the top end of the spring 16 being fixedly connected to the inner wall of the first rectangular shell 14.

[0027] In this embodiment, the cleaning mechanism is used to scrape off impurities at the bottom of the housing 1. During operation, the servo motor 12 drives the screw 11 to rotate through the first coupling, causing the screw sleeve 13 to move axially along the screw 11, so that the first rectangular shell 14 fixed on the screw sleeve 13 moves synchronously. The second rectangular shell 15 is elastically supported by the spring 16 so that the scraper 17 at the bottom of the housing 1 always fits against the inner wall of the bottom of the housing 1. When the first rectangular shell 14 moves, the scraper 17 scrapes off the solidified paint impurities at the bottom of the housing 1 under the pressure of the spring 16. The elastic deformation of the spring 16 allows the scraper 17 to adapt to the tilt of the bottom of the housing 1, ensuring that the cleaning effect is uniform and thorough, achieving impurity cleaning without manual intervention, which can save workers' physical strength and time.

[0028] In a further preferred embodiment of the present invention, the surface treatment structure for the rust-proof steel leaf spring seat further includes a rotating mechanism mounted on the housing 1 for rotating the steel leaf spring seat.

[0029] In this embodiment, the rotating mechanism is used to rotate the leaf spring seat so that the leaf spring seat can be uniformly treated to prevent rust.

[0030] In a further preferred embodiment of the present invention, the rotating mechanism includes: a dual-axis motor 18 fixedly installed on the top of the housing 1, the output shaft of the dual-axis motor 18 being connected to a rotating rod 19 via a second coupling, one end of the rotating rod 19 being fixedly installed with a first sprocket 20; a second sprocket 21 fixedly installed on the rotating shaft 5; and a chain 22 sleeved on the first sprocket 20 and the second sprocket 21.

[0031] In this embodiment, when the rotating mechanism is in use, the dual-axis motor 18 is started. The dual-axis motor 18 drives the rotating rod 19 to rotate through the second coupling. The rotating rod 19 drives the first sprocket 20 to rotate. The first sprocket 20 drives the second sprocket 21 to rotate through the chain 22. The second sprocket 21 drives the placement frame 6 to rotate through the rotating shaft 5. This allows the steel leaf spring seat fixed on the placement frame 6 to rotate, so that the paint spray head above can evenly spray the anti-rust coating onto the surface of the steel leaf spring seat.

[0032] In a further preferred embodiment of the present invention, a protective shell 23 is fixedly installed on the outer wall of the housing 1, and the protective shell 23 is used to cover the first sprocket 20, the second sprocket 21 and the chain 22.

[0033] In this embodiment, the use of the protective shell 23 can prevent workers from accidentally touching the first sprocket 20, the second sprocket 21 and the chain 22 in the working state, thus protecting the workers.

[0034] In a further preferred embodiment of this utility model, a limiting rod is fixedly installed on the placement rack 6, the limiting rod is slidably connected to the clamping plate 9, and the bottom of the box 1 is provided with a discharge port for discharging impurities.

[0035] In this embodiment, the use of the limiting rod ensures the stability of the clamp 9 during movement, and the use of the discharge port allows the scraped impurities to be discharged so that workers can collect them using a container.

[0036] In a further preferred embodiment of the present invention, a limiting block is welded onto the threaded sleeve 13, and the limiting block is slidably connected to the limiting groove on the housing 10.

[0037] In this embodiment, by using the limiting block and the limiting groove together, it can be ensured that the screw sleeve 13 will not rotate during the movement. When the screw sleeve 13 moves, the limiting block connected to it will also slide in the limiting groove at the same time.

[0038] In a further preferred embodiment of the present invention, a support base for supporting the rotating rod 19 is fixedly installed on the top of the box 1, the support base is rotatably connected to the rotating rod 19, and a door is provided on the loading and unloading port of the box 1.

[0039] In this embodiment, the use of a support base can improve the stability of the rotating rod 19 during operation, and prevent the first sprocket 20 from being unstable during rotation due to excessive length.

[0040] In a further preferred embodiment of the present invention, a conveying pipe for conveying anti-rust coating is fixedly installed on the top of the box 1, and a flexible hose is fixedly installed at the bottom end of the conveying pipe. One end of the flexible hose is fixedly connected to the diversion pipe 4, and the flexible hose is connected to the interior of the diversion pipe 4.

[0041] In this embodiment, the combined use of the delivery pipe and the hose allows workers to easily deliver the anti-rust coating to the diversion pipe 4 and the spray nozzle using appropriate equipment.

[0042] In summary, compared with related technologies, this solution, through the use of electric push rod 8, enables clamping plate 9 to be moved to firmly fix the steel leaf spring seat to be treated for rust prevention onto the placement frame 6. Through the use of electric slide rail 2, connecting rod 3 can drive the diversion pipe 4 and spray head to move, allowing the spray head to uniformly spray the surface of the steel leaf spring seat, thereby achieving rust prevention treatment. During the spraying process, the paint dripping onto the bottom of the housing 1 will form solid impurities after a period of time. After the spraying operation is completed, if it is necessary to clean these impurities, the cleaning mechanism can be activated. The cleaning mechanism can remove the solidified impurities by mechanical scraping, and the cleaned impurities will be discharged from the center of the bottom of the housing 1 to keep the bottom of the housing 1 clean. This solves the technical problem that existing spraying equipment for rust prevention treatment of steel leaf spring seats requires manual handling of paint impurities at the bottom of the device, increasing the labor intensity and time consumption for workers.
