Description

Technical Field

[0001] This utility model relates to the technical field of surface treatment equipment for threaded components, specifically a surface treatment device for threaded components. Background Technology

[0002] Threaded components are common connecting parts in mechanical engineering and are widely used in automobile manufacturing, aerospace, construction engineering and furniture manufacturing. The surface treatment of threaded components is crucial to their performance and service life. Surface treatment devices can be divided into chemical treatment, physical treatment and electrochemical treatment. Chemical treatment includes oxidation treatment, phosphating treatment, etc.; physical treatment includes sandblasting treatment, polishing treatment, etc.; electrochemical treatment includes electroplating treatment, electrophoresis treatment, etc.

[0003] In the prior art, such as Chinese patent CN213944159U, a metal surface treatment device is disclosed, belonging to the field of metal product surface treatment technology. It includes a base, a cleaning tank vertically arranged on the base, a horizontally arranged support frame vertically slidingly connected in the cleaning tank, a cleaning basket arranged in the support frame, a vertically arranged lead screw rotatably connected in the cleaning tank, the lead screw passing through one side of the support frame and threaded to the support frame, a bevel gear one fixedly connected to the bottom end of the lead screw, a bevel gear two rotatably connected to the bottom of the cleaning tank, the bevel gear two meshing with the bevel gear one, a rotating shaft fixedly connected at the axis of the bevel gear two, a blower device arranged on the side of the base near the cleaning tank, and an ultrasonic device arranged in the cleaning tank.

[0004] Currently, most chemical treatment methods for threaded components require pouring chemicals into a treatment tank and then immersing the threaded components in the tank. This allows the chemicals to react with the surface of the threaded components, forming an oxide film that improves the performance and service life of the threaded components. However, the threaded components need to be removed after immersion, and existing equipment removes them directly, resulting in the waste of residual chemicals on the surface of the threaded components and increasing the processing cost of the equipment.

[0020] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0021] This utility model provides a technical solution: such as Figure 1 - Figure 4As shown, in this embodiment, a surface treatment device for threaded components includes a surface treatment tank 1. A rotating rod 2 is rotatably connected inside the surface treatment tank 1, with one end of the rotating rod 2 rotatably connected to the inner wall of the surface treatment tank 1. Rotating disks 3 are fixedly connected to both sides of the outer surface of the rotating rod 2. Four placement racks 4 are arranged between the two rotating disks 3. Connecting racks 5 are fixedly connected to both sides of the upper end of the four placement racks 4. Four connecting rods 6 are fixedly connected to one side of each of the two rotating disks 3. The outer surfaces of the eight connecting rods 6 are rotatably connected to the inner walls of the eight connecting racks 5 respectively. An L-shaped mounting bracket 7 is fixedly connected to one side of the surface treatment tank 1. A gear ring 16 is fixedly connected to one side of the L-shaped mounting bracket 7. A driving device 9 is fixedly mounted on the other side of the L-shaped mounting bracket 7. A rotating shaft 10 is drivenly connected to the output end of the driving device 9. One end of the rotating shaft 10 is rotatably connected to one side of the surface treatment tank 1. A fixing rod 18 is fixedly connected to one side of the outer surface of the rotating shaft 10. A rotating shaft 22 is rotatably connected to one end of the fixing rod 18. A driven component is fixedly connected to one end of the rotating shaft 22. Gear 19, the outer surface of which meshes with the inner wall of gear ring 16, is connected to the other end of rotating shaft 22. Rotating rod 20 is fixedly connected to one end of rotating rod 20. A lever 21 is fixedly connected to one end of rotating rod 20. A shaped disk 8 is fixedly connected to the other end of rotating rod 22. Four levers 17 are fixedly connected to one side of shaped disk 8. The outer surface of lever 21 is slidably connected to the inner wall of any lever 17. By activating the drive device 9, rotating shaft 10 drives fixed rod 18 to rotate, and driven gear 19 meshes with gear ring 16, causing... The rotating rod 20 rotates on its own. During the rotation, the actuating column 21 periodically enters the actuating frame 17, causing the shaped disk 8 to rotate intermittently, thereby causing the placement frame 4 to rotate intermittently. This allows the placement frame 4 inside the chemical reagent to undergo surface treatment, and the threaded elements on the placement frame 4 that rotate out of the chemical reagent to be drained. This structure is simple, easy to operate, effectively avoids waste of chemical reagents, and reduces production costs. The middle part of the gear ring 16 is rotatably connected to one side of the outer surface of the rotating shaft 10.

[0022] like Figure 3 and Figure 4 As shown, a limiting disk 11 is fixedly connected to the other side of the outer surface of the rotating shaft 10. Four limiting grooves 23 are opened on the outer surface of the irregular disk 8. The outer surface of the limiting disk 11 is slidably connected to the inner wall of any limiting groove 23. Through the structural design of the limiting groove 23 and the limiting disk 11, the irregular disk 8 can be limited to prevent tilting and improve stability.

[0023] like Figure 1 and Figure 3 As shown, a reinforcing rib 24 is fixedly connected to one side of the lower end of the L-shaped mounting bracket 7. One side of the reinforcing rib 24 is fixedly connected to one side of the surface treatment pool 1. Through the structural design of the reinforcing rib 24, the stability of the L-shaped mounting bracket 7 can be improved.

[0024] like Figure 3 and Figure 4 As shown, each of the four placement racks 4 has a drain opening 14 extending through its upper end, and each of the four placement racks 4 has a multiple placement platform 15 fixedly connected to its upper end. Through the structural design of the drain opening 14, the chemical agent drained from the surface of the threaded element is returned to the surface treatment tank 1 for reuse.

[0025] like Figure 1 As shown, a protective cover 12 is fixedly connected to the upper end of the surface treatment tank 1, and a fan 13 is fixedly installed on the inner wall of the protective cover 12. Through the structural design of the protective cover 12 and the fan 13, when the placement rack 4 that has just been removed from the chemical agent is drained, the fan 13 is turned on to quickly blow the chemical agent on the surface of the threaded element into the surface treatment tank 1 and dry it, thereby improving the draining efficiency of the equipment.

[0026] like Figure 1 As shown, a drain pipe 25 is fixedly connected to the other side of the surface treatment tank 1. A valve 26 is fixedly installed on one side of the drain pipe 25. Through the structural design of the valve 26 and the drain pipe 25, the chemical agents that have been used for a long time in the surface treatment tank 1 can be drained and replaced.

[0027] This utility model provides a surface treatment device for threaded components, the specific working principle of which is as follows:

[0028] When surface treating threaded components, threaded components are first placed on all four racks 4. After the surface treatment of the threaded components soaked in the chemical agent is completed, the drive device 9 is turned on, and the rotating shaft 10 drives the fixed rod 18 to rotate. The driven gear 19 meshes with the gear ring 16, causing the rotating rod 20 to rotate. During the rotation of the rotating rod 20, the actuating column 21 periodically enters the actuating frame 17, driving the shaped disc 8 to rotate intermittently, thereby driving the racks 4 to rotate intermittently. The soaked threaded components are removed from the chemical agent, and the racks 4 that are not soaked are put into the chemical agent. While soaking, the racks 4 that have just been removed from the chemical agent are drained. At the same time, the fan 13 is turned on to quickly blow the chemical agent on the surface of the threaded components into the surface treatment tank 1 and dry them. The above operation is repeated. When the threaded components on the drained racks 4 are moved to the position of the workers, the threaded components are removed and the untreated threaded components are placed.

[0029] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
