An electric push rod 309 is provided at both the upper and lower ends of each Z-shaped plate 308. The output end of the electric push rod 309 is connected to a moving plate 310.

[0025] Specifically, through the cooperation of the stepper motor A301, the incomplete gear 303, and the rotating gear 304 in the intermittent processing component 3, the intermittent rotation of the piston rod can be realized, which is convenient for comprehensive cleaning and coating operations and improves the processing efficiency.

[0026] In this embodiment, the upper end of the moving plate 310 is connected to an installation frame 311. A stepper motor B312 is provided on the installation frame 311. The output end of the stepper motor B312 is connected to a follower shaft 313. The follower shaft 313 is connected to a chuck 314.

[0027] Specifically, the piston rod can be stably fixed through the chuck 314 in the intermittent processing component 3.

[0028] In this embodiment, the lower end of the rotating column 306 is connected to a plurality of support columns 307 distributed in a circular pattern. Each support column 307 is slidably connected to the installation box 2.

[0029] Specifically, the support column 307 plays a role in stably supporting the rotating column 306, ensuring the stability and reliability of the intermittent processing component 3 during operation.

[0035] Working principle: First, install the piston rod of the hydraulic rod to be processed on the chuck 314 of the intermittent processing component 3. After starting the device, the controller 7 controls the dust cleaning component 4 to start working. The water in the water tank 402 enters the multiple high-pressure nozzles A404 in the cleaning tank 401 through the water inlet pipe 403. The high-pressure nozzles A404 spray high-pressure water flow onto the surface of the piston rod to remove impurities such as dust on the surface of the piston rod. The cleaned sewage flows into the collection tank 406 through the water outlet pipe 405 for collection for subsequent processing. Then, the controller 7 controls the intermittent processing component 3 to work. The stepping motor A301 starts, driving the rotating shaft A302 to rotate, and then the incomplete gear 303 rotates. The incomplete gear 303 meshes with the rotating gear 304, driving the rotating gear 304 to rotate intermittently. The rotating gear 304 drives the rotating column 306 to rotate through the rotating shaft B305. The multiple Z-shaped plates 308 on the rotating column 306 and the piston rod installed on the Z-shaped plates 308 rotate accordingly. At the same time, the stepping motor B312 on the mounting frame 311 can drive the follower shaft 313 and the chuck 314 to rotate, enabling the piston rod itself to rotate as well, so as to perform cleaning and coating in all directions. Then, when the piston rod has been cleaned, the stepping motor indirectly drives the piston rod to move upward and then out of the cleaning tank 401 at this time. When the piston rod rotates to the position of the electric hot air blower 6, the electric hot air blower 6 starts and blows hot air on the coated piston rod to accelerate the drying process of the coating liquid. Next, the piston rod rotates to the position of the coating component 5 (before this, the output end of the electric push rod 309 indirectly drives the piston rod to move upward first and then downward). The coating liquid in the liquid storage tank 501 enters the multiple high-pressure nozzles B504 in the coating tank 502 through the liquid outlet pipe 503. The high-pressure nozzles B504 spray the coating liquid onto the surface of the piston rod, making the coating liquid evenly cover the surface of the piston rod. This utility model realizes that the dust cleaning component 4 can effectively remove impurities such as dust on the surface of the piston rod, providing a clean surface for subsequent coating, ensuring the tight combination of the coating layer and the piston rod, and improving the uniformity and firmness of the coating.

[0036] Although the embodiments of the present utility model have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principle and spirit of the present utility model. The scope of the present utility model is defined by the appended claims and their equivalents.
