Description

Technical Field

[0001] This utility model relates to the field of hydraulic cylinder processing technology, and in particular to a hydraulic cylinder surface spraying device. Background Technology

[0002] A hydraulic cylinder is a hydraulic actuator that converts hydraulic energy into mechanical energy and performs linear reciprocating or oscillating motion. It has a simple structure and reliable operation. When used to achieve reciprocating motion, a speed reduction device can be eliminated, and there is no transmission backlash, resulting in smooth movement. Therefore, it is widely used in the hydraulic systems of various machines. In the production process of hydraulic cylinders, in order to improve their wear resistance, corrosion resistance and service life, it is usually necessary to spray coating their surface.

[0003] In existing anti-rust painting technology for hydraulic cylinders, the painting operation involves suspending the hydraulic cylinder on a bracket and having an operator hold a paint gun and spray paint around the cylinder. This manual painting method is inefficient and lacks automation. Prolonged painting work can cause significant harm to workers. Furthermore, manual painting can sometimes result in accidental spraying of the piston rod, affecting the quality of the hydraulic cylinder. In addition, after manual painting, the anti-rust paint tends to accumulate at the bottom of the cylinder due to gravity, resulting in uneven thickness of the anti-rust layer at both ends of the cylinder, affecting the product's appearance and anti-rust effect.

[0004] Existing patent (publication number: CN213670124U) discloses a surface spraying device for a hydraulic cylinder, including a worktable, a hydraulic cylinder body, a translation mechanism, a lifting mechanism, a spraying ring, and a heating ring. The worktable has a through hole on its surface, and the hydraulic cylinder body is placed upside down within the through hole, with the end cap of the hydraulic cylinder body fitting against the worktable surface. A translation mechanism is located on one side of the worktable, and a lifting mechanism is located on the slide of the translation mechanism. The lifting mechanism includes guide rods, a top beam, and other structures. The guide rods are symmetrically arranged on the top surface of the slide, and a bearing plate is slidably connected between the guide rods. A top beam is located on the top surface of the guide rods, and a cylinder is located between the top beam and the bearing plate. A spraying ring concentric with the through hole is located on the side of one bearing plate, and a heating ring concentric with the through hole is located on the side of the other bearing plate. This application has a reasonable design, simple operation, wide applicability, uniform spraying, and rapid drying, greatly improving spraying efficiency and showing promising application prospects.

[0005] To address the aforementioned issues, existing patents offer solutions that involve spraying the hydraulic cylinder with multiple nozzles within a spraying ring. However, the hydraulic cylinder remains stationary during the spraying process, resulting in angles between the nozzles, making it difficult to ensure uniform spraying. Furthermore, it is inconvenient to adjust the spraying distance based on the size of the hydraulic cylinder, and the cylinder cannot be directly dried after spraying; the spraying and drying stations must be switched back and forth, which is quite cumbersome.

[0006] To address this, a hydraulic cylinder surface spraying device is proposed. Utility Model Content

Detailed Implementation

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] Please see Figure 1-5 The present invention provides the following technical solution:

[0028] A hydraulic cylinder surface spraying device includes a base 1, a fixed rotating assembly 2 is provided on the right side of the top of the base 1, and a spraying and drying assembly 3 is provided on the left side of the top of the base 1.

[0029] The fixed rotating assembly 2 includes an L-shaped frame 201, which is fixedly connected to the right side of the top of the base 1. A support plate 202 is fixedly connected to the bottom left side of the L-shaped frame 201. A rotary motor 203 is fixedly connected to the bottom of the support plate 202. The output shaft of the rotary motor 203 passes through the support plate 202 and is fixedly connected to a rotary table 204. A first electric telescopic rod 205 is fixedly connected to the left side of the top of the L-shaped frame 201. The output rod of the first electric telescopic rod 205 passes through the L-shaped frame 201 and is rotatably connected to a clamping plate 206 through a bearing seat.

[0030] In this embodiment: by setting up a base 1, a fixed rotating component 2, and a spray drying component 3, the base 1 provides a supporting foundation for the entire device during use. The fixed rotating component 2 clamps and fixes the hydraulic cylinder to be sprayed, preventing it from shaking or shifting during the spraying process. It also drives the hydraulic cylinder to rotate at a uniform speed, ensuring that the surface of the hydraulic cylinder is fully and evenly sprayed, effectively improving the uniformity of the spray coating. The spray drying component 3 allows for the spraying of the hydraulic cylinder and facilitates easy adjustment of the spraying distance according to the size of the hydraulic cylinder. After spraying, the sprayed liquid on the surface of the hydraulic cylinder can be directly dried without repeatedly switching between spraying and drying stations, which is quite convenient.

[0031] Specifically, such as Figure 1 , Figure 2 , Figure 4 As shown, the spray drying assembly 3 includes a vertical housing 301, which is fixedly connected to the left side of the top of the base 1. A forward and reverse motor 302 is fixedly connected to the top of the vertical housing 301. A threaded rod 303 is fixedly connected to the output shaft of the forward and reverse motor 302. The bottom of the threaded rod 303 extends through to the bottom of the vertical housing 301. An internal threaded block 304 is threadedly connected to the surface of the threaded rod 303. The side of the internal threaded block 304 closest to the inner wall of the vertical housing 301 is slidably connected to the inner wall of the vertical housing 301. A second electric telescopic rod 305 is fixedly connected to the right side of the internal threaded block 304.

[0032] Specifically, such as Figure 1 , Figure 2 , Figure 4 As shown, the output rod of the second electric telescopic rod 305 is fixedly connected to a fixing plate 306, the top of the fixing plate 306 is fixedly connected to a spray gun 307, and the bottom of the fixing plate 306 is fixedly connected to a hot air drying gun 308.

[0033] Specifically, such as Figure 4 As shown, the top and bottom of the inner wall of the vertical housing 301 are provided with first movable holes 4 for use with threaded rod 303. The top and bottom of the surface of the threaded rod 303 are respectively rotatably connected to the inner walls of the two first movable holes 4 through bearings.

[0034] In this embodiment: by setting up a vertical housing 301, a forward / reverse motor 302, a threaded rod 303, an internal threaded block 304, a second electric telescopic rod 305, a fixing plate 306, a spray gun 307, a hot air drying gun 308, and a first movable hole 4, in use, by starting the forward / reverse motor 302, the output shaft of the forward / reverse motor 302 drives the threaded rod 303 to rotate forward or in reverse. Due to the forward or reverse rotation of the threaded rod 303, the internal threaded block 304 slides upward or downward within the vertical housing 301 under the action of the thread. The internal threaded block 304, through the second electric telescopic rod 305 and the fixing plate 306, drives the spray gun 307 and the hot air drying gun 308 to move upward or downward at a uniform speed, thereby enabling... The heights of the spray gun 307 and the hot air drying gun 308 can be adjusted. The second electric telescopic rod 305 can be activated, causing its output rod to extend or retract, which in turn moves the fixed plate 306 left and right. This allows for adjustment of the spraying and drying distances of the spray gun 307 and the hot air drying gun 308 according to the size of the hydraulic cylinder. The hydraulic cylinder can then be sprayed by connecting the spray gun 307 to the spray liquid supply equipment. After spraying, the spray liquid on the surface of the hydraulic cylinder can be dried directly using the hot air drying gun 308, which is convenient. The first movable hole 4 allows the threaded rod 303 to pass through the vertical housing 301 and rotate easily via the bearing.

[0035] Specifically, such as Figure 3 As shown, the bottom of the support plate 202 is provided with a second movable hole 5 for use with the rotary motor 203. The output shaft surface of the rotary motor 203 is rotatably connected to the inner wall of the second movable hole 5 through a bearing.

[0036] Specifically, such as Figure 3 As shown, the top of the L-shaped frame 201 is provided with a through hole 6 for use with the first electric telescopic rod 205. The output shaft surface of the first electric telescopic rod 205 is slidably connected to the inner wall of the through hole 6, and a rubber pad 7 is fixedly connected to the bottom of the clamping plate 206.

[0037] In this embodiment: by providing a second movable hole 5, the output shaft of the rotary motor 203 can pass through the support plate 202 and rotate easily through the bearing; by providing a through hole 6, the output rod of the first electric telescopic rod 205 can pass through the through hole 6 for telescopic output; by providing a rubber pad 7, damage caused by rigid contact between the clamping plate 206 and the hydraulic cylinder can be avoided, and friction can be increased to improve the clamping stability of the hydraulic cylinder.

[0038] Specifically, such as Figure 1 , Figure 2As shown, a control panel 8 is provided on the left side of the top front side of the base 1, which is used in conjunction with the fixed rotation assembly 2 and the spray drying assembly 3. A fixed bracket 9 is fixedly connected to the bottom of the control panel 8, and the bottom of the fixed bracket 9 is fixedly connected to the left side of the top front side of the base 1.

[0039] Specifically, such as Figure 1 , Figure 2 , Figure 5 As shown, an elastic anti-slip pad 10 is fixedly connected to the bottom of the base 1, and the bottom of the elastic anti-slip pad 10 is provided with anti-slip texture.

[0040] In this embodiment: by setting up the control panel 8, the fixed rotating component 2 and the spray drying component 3 can be easily controlled to work. By setting up the fixed bracket 9, the control panel 8 can be supported and fixed. By setting up the elastic anti-slip pad 10, the anti-slip function can be achieved, thereby improving the stability of the base 1.

[0041] Working Principle: In use, first, place the hydraulic cylinder to be sprayed on top of the rotary table 204. Then, activate the first electric telescopic rod 205 via the control panel 8. This causes the output rod of the first electric telescopic rod 205 to drive the clamping plate 206 downwards through the bearing seat until the rubber pad 7 is tightly fitted with the hydraulic cylinder. The clamping plate 206 and the rotary table 204 then clamp and fix the hydraulic cylinder, preventing it from shaking or shifting during spraying. Next, activate the rotary motor 203 via the control panel 8. This causes the output shaft of the rotary motor 203 to drive the rotary table 204 to rotate at a constant speed. The rotary table 204 then drives the clamped hydraulic cylinder to rotate at a constant speed, ensuring that the surface of the hydraulic cylinder receives a comprehensive and uniform spray during spraying, effectively improving the spray uniformity. Finally, activate the forward and reverse motor 302 via the control panel 8. This causes the output shaft of the forward and reverse motor 302 to drive the threaded rod 303 in the forward direction. Alternatively, the rotation can be reversed. The internal threaded block 304, through the forward or reverse rotation of the threaded rod 303, slides upward or downward within the vertical housing 301 under the action of the threads. The internal threaded block 304, via the second electric telescopic rod 305 and the fixing plate 306, drives the spray gun 307 and hot air drying gun 308 to move upward or downward at a uniform speed, thus allowing adjustment of their heights. Furthermore, the second electric telescopic rod 305 can be activated via the control panel 8, causing its output rod to extend or retract, which in turn moves the fixing plate 306 left or right. This allows adjustment of the spraying and drying distances of the spray gun 307 and hot air drying gun 308 according to the size of the hydraulic cylinder. Then, by connecting the spray gun 307 to the spraying liquid supply equipment, the hydraulic cylinder can be sprayed. After spraying, the spraying liquid on the surface of the hydraulic cylinder can be directly dried using the hot air drying gun 308, which is quite convenient.

[0042] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
