Description

Technical Field

[0001] This utility model relates to the field of hydraulic cylinder processing technology, and more specifically, to a spraying device for surface treatment of hydraulic cylinders. Background Technology

[0002] A hydraulic cylinder is a hydraulic actuator that converts hydraulic energy into mechanical energy and performs linear reciprocating motion. It has a simple structure and reliable operation. When used to achieve reciprocating motion, it eliminates the need for a speed reduction device, eliminates transmission backlash, and provides smooth movement. Therefore, it is widely used in the hydraulic systems of various machines.

[0003] Currently, during the production of hydraulic cylinders, their outer surfaces require spray coating to improve their corrosion and wear resistance. Existing spray coating devices mostly employ fixed nozzles or manual hand-held nozzles: when using a fixed nozzle, the hydraulic cylinder needs to be manually adjusted in angle and position, resulting in uneven coating thickness and inconvenient operation; while manual hand-held nozzles offer flexibility, their work efficiency is low, and human error is significant, making it difficult to ensure coating consistency. Therefore, it is necessary to propose a spray coating device for the surface treatment of hydraulic cylinders to solve the above problems. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides a spraying device for surface treatment of hydraulic cylinders, which aims to improve the existing spraying devices that mostly use fixed nozzles or manual hand-held nozzles for operation: when using a fixed nozzle, the hydraulic cylinder needs to be manually adjusted in terms of angle and position, resulting in uneven coating thickness and inconvenient operation; although the manual hand-held nozzle can be flexibly adjusted, the operation efficiency is low and the manual operation error is large, making it difficult to ensure the consistency of the coating.

The movable frame 132 is threaded through the first threaded rod 131 and is slidably connected to the first slide groove 111. Here, the position of the movable frame 132 can be adjusted by rotating the first threaded rod 131 through the rotating handwheel 133, thereby meeting the spraying requirements of hydraulic cylinder bodies of different lengths.

[0022] Please see Figures 1-4 The spraying structure 200 includes a surrounding plate 210, a rotating fixing component 230, and a spraying component 250. The surrounding plate 210 is fixed on the spraying operating table 110. A second sliding groove 211 is provided on one side of the surrounding plate 210. The rotating fixing component 230 is installed and fixed on the surrounding plate 210 and the adjusting component 130. A traction component 240 is also installed on the surrounding plate 210. The spraying component 250 is installed on the traction component 240 and the spraying operating table 110.

[0023] A protective cover 220 is hinged to the top surface of the enclosure 210. A handle 221 is installed on one side of the protective cover 220. The protective cover 220 is designed to prevent paint from flying and affecting human health. The rotating fixing component 230 includes a hydraulic cylinder 231 and a first servo motor 232. The hydraulic cylinder 231 is installed on one side of the enclosure 210, and the first servo motor 232 is installed on the movable frame 132. The output end of the hydraulic cylinder 231 is rotatably connected to a clamping block 233. The end of the output shaft of the first servo motor 232 is fixed to the clamping block 233. The surface of the clamping block 233 has a conical clamping groove. Here, the hydraulic cylinder body can be placed between two clamping blocks 233. Then, the hydraulic cylinder body is fixed in the conical clamping groove on the surface of the clamping block 233 by the hydraulic cylinder 231, and rotated by the first servo motor 232.

[0024] The traction component 240 includes a second servo motor 241 and a second threaded rod 242. The second servo motor 241 is mounted on one side of the enclosure 210, and the second threaded rod 242 is rotatably connected to the enclosure 210. The end of the output shaft of the second servo motor 241 is connected to the second threaded rod 242. A sliding sleeve 243 is threaded through the second threaded rod 242. A limit plate 244 is fixed to one side of the sliding sleeve 243, and the limit plate 244 slides through the second sliding groove 211. The spraying component 250 includes a spraying pump 251, a connecting pipe 254, and a material box 256. The spraying pump 251 is mounted on the spraying operating table 110. On one side, the inlet and outlet of the spray pump 251 are respectively equipped with an inlet hose 252 and an outlet hose 253.

The end of the outlet hose 253 is connected to a connecting pipe 254, which is installed through the limiting plate 244 and the sliding sleeve 243. The end of the connecting pipe 254 is equipped with a nozzle 255. Here, the second servo motor 241 works to drive the second threaded rod 242 to rotate, thereby driving the nozzle 255 to move back and forth. This makes the spraying more uniform and more efficient.

[0025] Specifically, the working principle of the hydraulic cylinder surface treatment spraying device is as follows: During use, the first threaded rod 131 is rotated by rotating the handwheel 133, causing the movable frame 132 to move on the first threaded rod 131, thereby adjusting the position between the first servo motor 232 and the hydraulic cylinder 231. After adjusting to a suitable position, the hydraulic cylinder body is placed between the two clamping blocks 233. The hydraulic cylinder 231 works to clamp the hydraulic cylinder body in the conical clamping groove between the two clamping blocks 233. The protective cover 220 is then placed on top. At this time, the second servo motor 241 works to drive the second threaded rod 242 to rotate. Simultaneously, the spraying pump 251 sprays the raw material in the material box 256 through the nozzle 255. During the rotation of the second threaded rod 242, the nozzle 255 can move. At the same time, the first servo motor 232 drives the hydraulic cylinder body to rotate. The sprayed raw material covers the hydraulic cylinder body to complete the spraying operation. This reduces manual intervention during the spraying process, which is beneficial to improving the efficiency of spraying, while reducing the error of the spraying thickness, making the spraying more uniform, and making it more convenient to use.

[0026] It should be noted that the specific models and specifications of the hydraulic cylinder 231, the first servo motor 232, the second servo motor 241, and the spray pump 251 need to be selected and determined according to the actual specifications of the device. The specific selection calculation method adopts the existing technology in this field, so it will not be described in detail.

[0027] The power supply and operating principle of the hydraulic cylinder 231, the first servo motor 232, the second servo motor 241 and the spray pump 251 are clear to those skilled in the art and will not be described in detail here.

Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
