[0002] Electrophoretic coating equipment is a comprehensive device integrating automated transmission, multi-stage surface treatment, and environmental control. Through processes such as chemical pretreatment, electrodeposition coating, and high-temperature curing, it forms a uniform and dense protective coating on the surface of components. The device adopts a closed-loop circulation system, which can achieve efficient recycling of processing liquids and solvents, reducing environmental pollution and production costs. Its processing is highly automated, and it can precisely control the coating thickness and uniformity, significantly improving the corrosion resistance, wear resistance, and fatigue resistance of components. This device is widely used in the surface protection treatment of key components such as railway track fasteners, vehicle connectors, and bogie components. It can meet the stringent requirements of the railway industry for long service life and high reliability of components, and is suitable for the production of new railway components and the refurbishment and maintenance of existing components. The hooks and latches of existing electrophoretic coating equipment are all individually designed, which is very inconvenient when picking up and dropping a large number of workpieces. They need to be engaged or unengaged one by one, which increases the workload of operators and reduces work efficiency. Utility Model Content

[0003] In view of the above situation and to overcome the defects of the prior art, this utility model provides a surface treatment device for railway accessories, which effectively solves the problem that the hooks and buckles of the existing electrophoretic coating device are all set separately, which is very inconvenient when picking up and taking up a large number of workpieces. They need to be locked or unlocked one by one, which increases the workload of operators and reduces work efficiency.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a surface treatment device for railway parts, comprising a base, a device body fixedly mounted on the top of the base, an electric push rod fixedly mounted on the top of the device body, the transmission end of the electric push rod extending into the interior of the device body and fixedly mounted with a connecting frame, an equipment box fixedly mounted on the bottom of the connecting frame, sliders fixedly mounted on both ends of the equipment box, grooves formed on both sides of the inner wall of the device body, two sliders slidably mounted inside the two grooves, several connecting rods fixedly mounted at equal intervals in a ring at the bottom of the equipment box, hooks fixedly mounted on the bottom ends of the connecting rods, and stop bars rotatably mounted on one side of each connecting rod, an electric pool fixedly mounted on the top of the device body and inside the device body, a servo motor fixedly mounted on one side of the bottom of the connecting frame, a transmission component provided at the output end of the servo motor, the transmission component being connected to several stop bars in a transmission manner, and when the servo motor operates, power is output to several stop bars through the transmission component, causing the several stop bars to rotate and open / close.

[0005] Preferably, the transmission assembly includes a drive shaft, which is fixedly mounted on the output end of the servo motor. A bearing is rotatably mounted on the surface of the drive shaft. One side of the bearing is fixedly connected to the inner wall of one side of the connecting frame via a fixing rod. A drive gear is fixedly mounted on the top of the drive shaft. The top of the drive gear is rotatably connected to one side of the top of the connecting frame via a shaft seat.

[0006] Preferably, a driven gear is meshed with one side of the driving gear, a threaded sleeve is fixedly installed in the middle of the driven gear, a threaded rod is threadedly connected to the middle of the threaded sleeve, the bottom end of the threaded rod extends into the inside of the equipment box and is fixedly installed with a support arm, a bushing is rotatably installed on the surface of the threaded sleeve, a support frame is fixedly installed on the surface of the bushing, and the bottom of the support frame is fixedly connected to the equipment box.

[0007] Preferably, limit blocks are fixedly installed at both ends of the support arm, and limit grooves are opened on the inner walls of both ends of the equipment box. The two limit blocks are slidably installed inside the two limit grooves. Several plug rods are rotatably installed at equal intervals in a ring at the bottom of the support arm. The lower ends of the plug rods extend to the bottom of the equipment box and are rotatably connected to the corresponding stop rods. The surface of the plug rods is covered with plug sleeves, and the plug sleeves are fixedly connected to the bottom of the equipment box.

[0008] Compared with the prior art, the beneficial effects of this utility model are as follows: During use, the operator starts the servo motor, which drives the drive shaft to rotate. The drive shaft's rotation drives the driven gear to rotate via the active gear. The driven gear's rotation causes the threaded sleeve to rotate inside the bushing. The rotation of the threaded sleeve drives the support arm to move upwards via the threaded rod. As the support arm moves, the limiting block slides inside the limiting groove, increasing the stability of the support arm's movement. The upward movement of the support arm also drives the insertion rod to move upwards along the inside of the bushing. The upward movement of the insertion rod also drives the stop lever to rotate upwards and open, allowing railway parts to be hooked or removed from the hook. This enables the hook and latch of the electrophoretic coating device to engage or unlock simultaneously, thereby reducing the operator's workload and improving work efficiency. After the operator hangs the railway parts, the operator starts the electric push rod to move the connecting frame down. When the connecting frame moves down, it also moves the equipment box down. When the equipment box moves down, the slider slides inside the slide groove, which increases the stability of the equipment box when it moves. When the equipment box moves down, it drives several hooks to move down through several connecting rods, thereby moving the railway parts into the electric pool for surface treatment.
