Technical Field

[0001] The present invention relates to the technical field of track link connecting shaft processing, and specifically to an oil immersion anti-rust treatment device for track link connecting shafts and an operation method thereof. Background Art

[0002] The track link connecting shaft is an important part for connecting track links. During the production and processing of track link connecting shafts, in order to enhance the product quality of track link connecting shafts, anti-rust treatment needs to be carried out on the track link connecting shafts. The traditional method is to spray anti-rust oil on the track link connecting shafts. This method has problems such as uneven spraying, poor anti-rust effect, and relatively large waste of anti-rust oil. For example, the patent with the application number 201922437206.1 discloses an anti-rust device for metal track products, which solves the problem of inability to perform anti-rust treatment on metal products in all directions, but it has problems such as inability to perform oil immersion anti-rust treatment on track link connecting shafts under high pressure, poor anti-rust uniformity, and low working efficiency.

[0003] Based on this, the applicant proposes an oil immersion anti-rust treatment device for track link connecting shafts and an operation method thereof. Summary of the Invention

The bearing column is movably installed on the pushing structure. Leak holes are provided on the side wall and bottom of the oil immersion barrel. A connecting cylinder is vertically provided at the bottom inside the oil immersion barrel, and the connecting cylinder is connected to the bearing column. The track link connecting shaft to be subjected to oil immersion anti-rust treatment is placed into the oil immersion barrel, the connecting cylinder inside the oil immersion barrel is connected to the bearing column, and the pushing structure pushes the bearing column and the oil immersion barrel installed on the bearing column to descend, so that the oil immersion barrel containing the track link connecting shaft enters the oil immersion tank. The anti-rust oil in the oil immersion tank enters the oil immersion barrel through the leak holes on the side wall and bottom of the oil immersion barrel, and performs oil immersion treatment on the track link connecting shaft in the oil immersion tank. After the oil immersion of the track link connecting shaft is completed, the oil immersion barrel is moved out of the oil immersion tank under the action of the bearing column by the pushing structure, the oil immersion barrel is removed from the bearing column, and the oil-immersed track link connecting shaft in the oil immersion barrel is taken out, which can improve the oil immersion efficiency and oil immersion quality of the track link connecting shaft.

The hydraulic cylinder and the piston rod can provide power for the vertical movement of the pushing plate, drive the oil immersion barrel and the track link connecting shaft in the oil immersion barrel to enter and exit the oil immersion tank, and improve the working efficiency of oil-immersing the track link connecting shaft.

[0008] Preferably, a limiting ring is provided on the pushing plate, and the column vertically penetrates through the limiting ring. The pushing plate moves vertically under the action of the hydraulic cylinder, and the limiting ring rises or falls along the column, playing a limiting role on the vertically moving pushing plate and improving the stability during the process of the oil immersion barrel and the track link connecting shaft in the oil immersion barrel entering and exiting the oil immersion tank.

[0009] Preferably, a blower and an infusion pump are provided on the top plate. An air delivery pipe is provided on the blower and passes through the push plate and extends into the fixed box. A liquid suction pipe and an infusion pipe are provided on the infusion pump. One end of the liquid suction pipe is connected to the bottom of the oil immersion tank, and the infusion pipe passes through the push plate and extends into the fixed box. The blower and the infusion pump can work simultaneously or independently. The blower inputs air flow into the fixed box through the air delivery pipe. The air flow in the fixed box flows into the connecting cylinder through the hollow bearing column and then flows into the oil immersion barrel through the through slots on the side wall of the connecting cylinder, blowing the rust preventive oil in the oil immersion barrel to make the rust preventive oil fully contact the surface of the connecting shaft of the track link. The air flow is discharged from the oil immersion barrel and gathers in the sealed oil immersion tank, increasing the air pressure in the oil immersion tank and performing high-pressure oil immersion on the connecting shaft of the track link, thereby improving the oil immersion rust prevention efficiency and quality of the connecting shaft of the track link. On the other hand, after the oil immersion of the connecting shaft of the track link is completed, the air flow blown by the blower blows the oil-immersed connecting shaft of the track link in the oil immersion barrel, quickly drying the rust preventive oil adsorbed on the surface of the connecting shaft of the track link and improving the drying efficiency of the connecting shaft of the track link. The infusion pump pumps out the rust preventive oil in the oil immersion barrel through the liquid suction pipe and transports it into the fixed box through the infusion pipe. The rust preventive oil in the fixed box flows into the hollow bearing column through the through holes on the bearing column and then flows back into the oil immersion tank through the connecting cylinder and the through slots on the side wall of the connecting cylinder, enabling the rust preventive oil to circulate between the oil immersion tank and the oil immersion barrel, making the rust preventive oil fully contact the connecting shaft of the track link and performing a sufficient oil immersion rust prevention treatment on the connecting shaft of the track link.

[0010] Preferably, a driving structure is provided on the push plate and is connected to the bearing column. The bearing column is provided with a hollow structure, and through holes are provided on the side wall of the bearing column in the fixed box. The driving structure drives the bearing column and the oil immersion barrel installed on the bearing column to rotate. The oil immersion barrel drives the connecting shaft of the track link to rotate in the oil immersion tank, enabling the rust preventive oil to quickly enter and exit the oil immersion barrel and performing an oil immersion treatment on the connecting shaft of the track link in the oil immersion tank. Through the through holes, the air flow and the rust preventive oil in the fixed box can quickly enter the hollow bearing column, preventing the accumulation of rust preventive oil in the fixed box.

[0011] Preferably, the driving structure includes a driving motor disposed on the pushing plate. A transmission shaft is provided on the driving motor. The transmission shaft extends into the fixed box, and a driving wheel is provided on the transmission shaft. A driven wheel is provided at the top of the bearing column in the fixed box, and the driven wheel is connected to the driving wheel by a belt. The driving motor drives the transmission shaft and the driving wheel on the transmission shaft to rotate. The driving wheel drives the driven wheel to rotate through the belt.

The oil immersion barrel drives the track link connecting shaft to rotate in the oil immersion tank, so that the anti-rust oil quickly enters and exits the oil immersion barrel, and the track link connecting shaft in the oil immersion tank is subjected to oil immersion treatment. After the oil immersion of the track link connecting shaft is completed, the bearing column drives the oil immersion barrel to rotate under the action of the driving motor. Under the action of centrifugal force, the anti-rust oil in the oil immersion barrel is quickly thrown out, which is convenient for drying the oil-immersed track link connecting shaft.

[0012] Preferably, a sealing ring is provided at the bottom of the pushing plate. The hydraulic cylinder and the piston rod push the pushing plate downward, so that the oil immersion barrel containing the track link connecting shaft enters the oil immersion tank.

The anti-rust oil in the oil immersion tank enters the oil immersion tank through the leakage holes on the side wall and bottom of the oil immersion barrel, and the track link connecting shaft in the oil immersion tank is subjected to oil immersion treatment. On the other hand, the sealing ring can prevent the anti-rust oil in the oil immersion tank from splashing out of the oil immersion tank, reducing the waste of anti-rust oil.

[0013] Preferably, a pressure sensor is provided at the bottom of the pushing plate. A pressure gauge is provided on the pushing plate, and the pressure gauge is connected to the pressure sensor. The pressure sensor can sense the air pressure in the oil immersion tank and be reflected in the pressure gauge. When the pressure in the oil immersion tank reaches the preset pressure value, the blower stops working, and the track link connecting shaft is subjected to high-pressure oil immersion to improve the oil immersion quality of the track link connecting shaft, thereby improving the anti-rust performance of the track link connecting shaft.

[0014] Preferably, the oil immersion barrel is detachably mounted on the bearing column through a connecting cylinder, and through grooves are provided on the side wall of the connecting cylinder. The connecting cylinder and the bearing column are connected by threads, which facilitates the installation or disassembly of the connecting cylinder on the bearing column and improves the installation or disassembly efficiency of the oil immersion barrel on the bearing column. Through the through grooves, the air flow or anti-rust oil entering the connecting cylinder can quickly enter the oil immersion barrel, and the track link connecting shaft in the oil immersion barrel is subjected to oil immersion or blowing and drying treatment, improving the oil immersion and anti-rust efficiency and drying efficiency of the track link connecting shaft, thereby improving the oil immersion and anti-rust quality of the track link connecting shaft.

[0015] An operation method for an oil immersion and anti-rust treatment device suitable for track link connecting shafts, the operation method comprising the following steps:

[0016] 1. Check whether the circuit of the chain track link connecting shaft oil immersion rust prevention treatment equipment is intact, and check whether the drive motor, hydraulic cylinder, blower, and liquid infusion pump are working properly;

[0017] 2. Inject liquid rust preventive oil into the oil immersion tank. Place the chain track link connecting shaft that needs to be treated with oil immersion rust prevention into the oil immersion barrel, and connect the connecting cylinder in the oil immersion barrel to the bearing column;

[0018] 3. Start the hydraulic cylinder. The hydraulic cylinder and piston rod push the push plate downward, so that the oil immersion barrel containing the chain track link connecting shaft enters the oil immersion tank. The sealing ring on the push plate contacts the inner wall of the top of the oil immersion tank to seal the oil immersion tank. The rust preventive oil in the oil immersion tank enters the oil immersion barrel through the leakage holes on the side wall and bottom of the oil immersion barrel, and the chain track link connecting shaft in the oil immersion tank is subjected to oil immersion treatment;

[0019] 4. Start the drive motor. The drive motor drives the transmission shaft and the driving wheel on the transmission shaft to rotate. The driving wheel drives the driven wheel to rotate through the belt. The driven wheel drives the bearing column and the oil immersion barrel installed on the bearing column to rotate. The oil immersion barrel drives the chain track link connecting shaft to rotate in the oil immersion tank, so that the rust preventive oil quickly enters and exits the oil immersion barrel, and the chain track link connecting shaft in the oil immersion tank is subjected to oil immersion treatment;

[0020] 5. Start the blower and / or the liquid infusion pump. The blower inputs air flow into the fixed box through the air delivery pipe. The air flow in the fixed box flows into the connecting cylinder through the hollow bearing column, and flows into the oil immersion barrel through the through slots on the side wall of the connecting cylinder, blowing the rust preventive oil in the oil immersion barrel, so that the rust preventive oil is in full contact with the surface of the chain track link connecting shaft. The air flow is discharged from the oil immersion barrel and gathers in the sealed oil immersion tank, increasing the air pressure in the oil immersion tank. The pressure sensor can sense the air pressure in the oil immersion tank and be reflected in the pressure gauge. When the pressure in the oil immersion tank reaches the preset pressure value, stop the operation of the blower to perform high-pressure oil immersion on the chain track link connecting shaft; The liquid infusion pump pumps out the rust preventive oil in the oil immersion barrel through the liquid suction pipe, transports it to the fixed box through the liquid infusion pipe, and the rust preventive oil in the fixed box flows into the hollow bearing column through the through holes on the bearing column, and flows back to the oil immersion tank through the connecting cylinder and the through slots on the side wall of the connecting cylinder, so that the rust preventive oil circulates between the oil immersion tank and the oil immersion barrel;

[0021] 6. After the oil immersion rust prevention of the chain track link connecting shaft is completed, turn off the liquid infusion pump to stop the circulating flow of the rust preventive oil. Start the hydraulic cylinder. The hydraulic cylinder and piston rod pull the push plate upward, driving the oil immersion barrel and the chain track link connecting shaft in the oil immersion barrel to move out of the rust preventive oil. The rust preventive oil in the oil immersion barrel flows out from the leakage holes on the side wall and bottom of the oil immersion barrel. The bearing column drives the oil immersion barrel to rotate under the action of the drive motor, and the centrifugal force causes the rust preventive oil in the oil immersion barrel to be quickly thrown out;

[0022] VII. Start the blower. The blower inputs air into the fixed box through the air duct. The air in the fixed box flows into the connecting cylinder through the hollow bearing column, and then flows into the oil immersion barrel through the through slots on the side wall of the connecting cylinder, so as to blow and wipe the chain track joint connecting shaft after oil immersion in the oil immersion barrel, and quickly dry the rust preventive oil adsorbed on the surface of the chain track joint connecting shaft.

[0023] VIII. After the surface of the chain track joint connecting shaft after oil immersion in the oil immersion barrel is dried, turn off the blower and the driving motor. Remove the connecting cylinder on the oil immersion barrel from the bearing column, take out the chain track joint connecting shaft after oil immersion in the oil immersion barrel, replace it with a new chain track joint connecting shaft and continue the oil immersion treatment.

10. An operating method applicable to the oil-immersion anti-rust treatment equipment for the track link connecting shaft according to any one of claims 1 to 9, characterized in that: The operation method comprises the following steps:

1. Check whether the circuit of the oil-immersed anti-rust treatment equipment of the track link connecting shaft is intact, and check whether the drive motor, hydraulic cylinder, blower and infusion pump are working properly; Second, inject liquid anti-rust oil into the oil immersion box, put the link shaft of the chain track that needs oil immersion anti-rust treatment into the oil immersion barrel, and connect the connecting tube in the oil immersion barrel with the bearing column; 3. Start the hydraulic cylinder. The hydraulic cylinder and the piston rod push the push plate downward, so that the oil-immersed barrel with the chain track segment connecting shaft enters the oil-immersed box. The sealing ring on the push plate contacts the inner wall of the top of the oil-immersed box to seal the oil-immersed box. The anti-rust oil in the oil-immersed box enters the oil-immersed box through the leakage holes on the side wall and bottom of the oil-immersed barrel, and the chain track segment connecting shaft in the oil-immersed box is oil-immersed. Fourth, start the drive motor, the drive motor drives the transmission shaft and the driving wheel on the transmission shaft to rotate, the driving wheel drives the driven wheel to rotate through the belt, the driven wheel drives the bearing column and the oil immersion barrel installed on the bearing column to rotate, the oil immersion barrel drives the chain track segment connecting shaft to rotate in the oil immersion box, so that the anti-rust oil quickly enters and exits the oil immersion barrel, and the chain track segment connecting shaft in the oil immersion box is oil-immersed; 5. Start the blower and / or the infusion pump. The blower inputs air flow into the fixed box through the air supply pipe. The air flow in the fixed box flows into the connecting tube through the hollow bearing column, and flows into the oil-immersed barrel from the through groove on the side wall of the connecting tube, blowing the anti-rust oil in the oil-immersed barrel so that the anti-rust oil is in full contact with the surface of the chain track segment connecting shaft. The air flow is discharged from the oil-immersed barrel and collected in the sealed oil-immersed box, increasing the air pressure in the oil-immersed box. The pressure sensor can sense the air pressure in the oil-immersed box and reflect it in the pressure gauge. When the pressure in the oil-immersed box reaches a preset pressure value, the blower is stopped and the chain track segment connecting shaft is immersed in high-pressure oil. The infusion pump draws out the anti-rust oil in the oil-immersed barrel through the suction pipe and transports it to the fixed box through the infusion pipe. The anti-rust oil in the fixed box flows into the hollow bearing column through the through hole on the bearing column, and flows back to the oil-immersed box through the connecting tube and the through groove on the side wall of the connecting tube, so that the anti-rust oil circulates between the oil-immersed box and the oil-immersed barrel.

6. After the chain track link shaft is oil-immersed for anti-rusting, turn off the infusion pump, stop the circulation of the anti-rust oil, start the hydraulic cylinder, and the hydraulic cylinder and the piston rod pull the push plate upward to drive the oil-immersed barrel and the chain track link shaft in the oil-immersed barrel to move out of the anti-rust oil. The anti-rust oil in the oil-immersed barrel flows out from the leakage holes on the side wall and bottom of the oil-immersed barrel. The bearing column drives the oil-immersed barrel to rotate under the action of the driving motor, and the anti-rust oil in the oil-immersed barrel is quickly thrown out under the action of centrifugal force.

7. Start the blower, which inputs air into the fixed box through the air pipe. The air in the fixed box flows into the connecting tube through the hollow bearing column, and flows into the oil-immersed barrel from the through groove on the side wall of the connecting tube. Blow the oil-immersed chain track section connecting shaft in the oil-immersed barrel to quickly dry the anti-rust oil adsorbed on the surface of the chain track section connecting shaft; 8. After the surface of the track link shaft after oil immersion in the oil immersion barrel is dry, turn off the blower and drive motor, remove the connecting tube on the oil immersion barrel from the bearing column, take out the track link shaft after oil immersion in the oil immersion barrel, replace it with a new track link shaft and continue the oil immersion treatment. After completing the oil immersion rust prevention operation of the track link shaft, clean up the impurities generated during the oil immersion rust prevention process of the track link shaft and cut off the power supply.
