The bearing seat body is cooled by the cooling mechanism to prevent overheating of the bearing seat body. The height position of the bearing seat body is adjustable, which improves the flexibility of the bearing seat body and solves the technical problems mentioned in the background technology.

[0022] The technical solution in the embodiment of the present application is to solve the problems of the above-mentioned background technology, and the overall idea is as follows: Embodiment 1: See also Figure 1-10 The present invention provides a technical solution: a rocker arm bearing seat, comprising a bearing seat body 1, a lubricating oil adding mechanism 3 and a cooling mechanism 4, the lower end of the bearing seat body 1 is provided with an adjusting base 2, the lubricating oil adding mechanism 3 is fixedly arranged at the top of the bearing seat body 1, the top of the bearing seat body 1 is provided with a refueling port 11, the inside of the bearing seat body 1 is provided with a flow channel 12, the lubricating oil adding mechanism 3 comprises a lubricating oil storage tank 31, a fixing cylinder 32 and a power mechanism 33, the power mechanism 33 comprises a driving plate 34, the driving plate 34 is fixedly connected to a piston rod 35, and the piston rod 35 is located at Inside the fixed cylinder 32, the fixed cylinder 32 is connected to the lubricating oil storage tank 31 through an oil extraction pipe 36, and a first one-way valve 37 is provided on the oil extraction pipe 36. The fixed cylinder 32 and the refueling port 11 are connected through an oil replenishment pipe 38, and a second one-way valve 39 is provided on the oil replenishment pipe 38. The cooling mechanism 4 includes a coolant storage tank 41, a pump body 42 and a cooling mechanism 43. The pump body 42 is connected to the bearing seat body 1 through a liquid inlet pipe 5, the bearing seat body 1 and the cooling mechanism 43 are connected through a liquid discharge pipe 6, and the cooling mechanism 43 and the coolant storage tank 41 are connected through a liquid return pipe 7.

[0023] Among them, the first one-way valve 37 and the second one-way valve 39 both have the function of one-way flow of the medium. The lubricating oil inside the lubricating oil storage tank 31 can enter the fixed cylinder 32 through the first one-way valve 37 and the oil extraction pipe 36 under the drive of external force, and the lubricating oil inside the fixed cylinder 32 is intercepted by the first one-way valve 37. The lubricating oil inside the fixed cylinder 32 can enter the refueling port 11 through the second one-way valve 39 and the oil replenishing pipe 38 under the drive of external force, and the lubricating oil inside the oil replenishing pipe 38 is intercepted by the second one-way valve 39.

[0024] A lubricating oil adding mechanism 3 is additionally provided at the top of the bearing seat main body 1, and lubricating oil is added to the bearing seat main body 1 at a regular time through the lubricating oil adding mechanism 3. The power mechanism 33 works to drive the driving plate 34, and the driving plate 34 drives the piston rod 35 to move synchronously, driving the piston rod 35 to perform reciprocating linear motion in the fixed cylinder 32. When the piston rod 35 is pulled outward under the drive of the power mechanism 33, the lubricating oil inside the lubricating oil storage tank 31 is extracted, and the lubricating oil enters the fixed cylinder 32 through the oil extraction pipe 36, and then the piston rod 35 is pushed inward under the drive of the power mechanism 33. The extracted lubricating oil enters the refueling port 11 through the oil replenishing pipe 38, and the lubricating oil is added to the bearing seat main body 1 through the refueling port 11.

[0025] The coolant storage tank 41 stores coolant inside, and the pump body 42 is used as a power source. When the pump body 42 is working, the coolant inside the coolant storage tank 41 is drawn out, and the coolant is transported to the liquid inlet pipe 5, enters the flow channel 12 of the bearing seat body 1 through the liquid inlet pipe 5, and flows in the flow channel 12. During the flow of the coolant, the bearing seat body 1 is cooled, and the coolant carrying waste heat is discharged through the drain port 14, enters the drain pipe 6, and enters the cooling mechanism 43 through the drain pipe 6. The coolant is cooled by the cooling mechanism 43, and the cooled coolant enters the return pipe 7, and flows back to the coolant storage tank 41 through the return pipe 7, thereby realizing a cooling cycle.

[0026] In some examples, the power mechanism 33 includes two groups of vertical plates 331, and a screw rod 333 and a sliding rod 334 are arranged between the two groups of vertical plates 331. One end of the screw rod 333 is connected to the motor 332. The screw rod 333 and the sliding rod 334 both pass through the driving plate 34, and the driving plate 34 and the sliding rod 334 are slidingly connected.

[0027] Among them, when the motor 332 is working, it drives the screw rod 333 to rotate, thereby driving the driving plate 34 to slide along the sliding rod 334, and the driving plate 34 drives the piston rod 35 to slide along the sliding rod 334 synchronously. By controlling the rotation direction and number of rotations of the output shaft of the motor 332, the push-pull and displacement distance of the piston rod 35 are controlled accordingly to achieve the addition of lubricating oil.

[0028] In some examples, a liquid inlet 13 is opened on one side surface of the bearing seat body 1, and a liquid discharge port 14 is opened on the other side surface of the bearing seat body 1. One end of the liquid inlet pipe 5 is connected to the pump body 42, and the other end of the liquid inlet pipe 5 is connected to the liquid inlet 13 of the bearing seat body 1.

[0029] Among them, the coolant enters the liquid inlet pipe 5 driven by the pump body 42, enters the flow channel 12 of the bearing seat body 1 through the liquid inlet pipe 5 and the liquid inlet port 13, and flows in the flow channel 12. The coolant after heat exchange is discharged through the drain port 14 and enters the drain pipe 6.

[0030] In some examples, one end of the drain pipe 6 is connected to the cooling mechanism 43 , and the other end of the drain pipe 6 is connected to the drain port 14 of the bearing seat body 1 .

[0031] The coolant discharged through the drain port 14 enters the drain pipe 6, and enters the cooling mechanism 43 through the drain pipe 6. The cooling mechanism 43 cools the coolant carrying waste heat so that the coolant can be put into use again.

[0032] In some examples, the cooling mechanism 43 includes a cooling lining 431, which is configured as a triangular prism structure, and a first semiconductor refrigeration sheet 432, a second semiconductor refrigeration sheet 433, and a third semiconductor refrigeration sheet 434 are fixedly disposed on three sides of the cooling lining 431, respectively, and the first semiconductor refrigeration sheet 432, the second semiconductor refrigeration sheet 433, and the third semiconductor refrigeration sheet 434 are connected in series.

[0033] In some examples, the first semiconductor refrigeration plate 432, the second semiconductor refrigeration plate 433 and the third semiconductor refrigeration plate 434 all include a hot end and a cold end. The cold ends of the first semiconductor refrigeration plate 432, the second semiconductor refrigeration plate 433 and the third semiconductor refrigeration plate 434 are in contact with the cooling lining 431. When the first semiconductor refrigeration plate 432, the second semiconductor refrigeration plate 433 and the third semiconductor refrigeration plate 434 are working, the DC power supply provides the energy required for the electron flow. The electrons start from one end of the N-type semiconductor, absorb heat through the P-type semiconductor, and then reach the N-type semiconductor to release heat. Every time they pass through an NP module, heat is sent from one side to the other, forming a temperature difference. The temperature of the cold end of the semiconductor refrigeration plate is reduced, and the cooling is conducted through the cooling lining 431. When the coolant carrying waste heat flows through the coil 437, the coolant is cooled.

[0034] In some examples, the hot ends of the first semiconductor refrigeration plate 432, the second semiconductor refrigeration plate 433 and the third semiconductor refrigeration plate 434 are all fixedly provided with heat sinks 435, and heat dissipation fans 436 are installed on the heat sinks 435. The heat dissipation area is increased by the heat sink 435 to improve the heat dissipation efficiency, and the hot ends of the semiconductor refrigeration plates are cooled. The heat dissipation efficiency is further improved by the heat dissipation fans 436. The cooling effect of the cold ends of the semiconductor refrigeration plates is ensured by efficiently cooling the hot ends of the semiconductor refrigeration plates.

[0035] In some examples, the cooling lining 431 is built with a coil 437, and the coil 437 is arranged as a spiral structure. One end of the coil 437 is connected to the drain pipe 6, and the other end of the coil 437 is connected to the return pipe 7. The spiral structure of the coil 437 extends the flow path in a limited space. When the coolant flows in the coil 437, the cooling time is extended, thereby improving the cooling effect of the coolant.

[0036] By adopting the above technical solution: The power mechanism 33 drives the driving plate 34, and the driving plate 34 drives the piston rod 35 to perform reciprocating linear motion in the fixed cylinder 32. When the piston rod 35 is pulled outward under the drive of the power mechanism 33, the lubricating oil inside the lubricating oil storage tank 31 is extracted, and the lubricating oil enters the fixed cylinder 32 through the oil extraction pipe 36. When the piston rod 35 is pushed inward under the drive of the power mechanism 33, the extracted lubricating oil enters the refueling port 11 through the oil replenishing pipe 38, and the lubricating oil is added to the bearing seat body 1 through the refueling port 11. A lubricating oil adding mechanism 3 is additionally provided at the top of the bearing seat body 1. Lubricating oil is added to the bearing seat body 1 at a regular interval through the lubricating oil adding mechanism 3, instead of manual addition, which saves time and effort and is beneficial to the maintenance of the bearing seat body 1.

[0037] A flow channel 12 is opened in the bearing seat body 1, and the coolant flows in the flow channel 12. The bearing seat body 1 is cooled during the flow. The bearing seat body 1 is cooled by the cooling mechanism 4 to prevent the bearing seat body 1 from overheating, thereby avoiding a series of negative effects caused by overheating and ensuring the stable use of the bearing seat body 1.

[0038] Embodiment 2: Based on Example 1, this example introduces a specific structure of an adjusting base 2 in a rocker arm bearing seat, studs 21 are fixedly provided on both sides of the upper end of the adjusting base 2, through holes 15 are opened on both sides of the lower end of the bearing seat body 1, the studs 21 of the adjusting base 2 are arranged corresponding to the through holes 15 of the bearing seat body 1, the studs 21 of the adjusting base 2 pass through the through holes 15 of the bearing seat body 1, the bearing seat body 1 and the adjusting base 2 are fixedly connected by locking nuts 22, two groups of locking nuts 22 are correspondingly arranged for one group of studs 21, and the two groups of locking nuts 22 are respectively located at the upper and lower ends of the connection position of the bearing seat body 1.

[0039] In some examples, notches 23 are provided on both sides of the adjustment base 2 , and the adjustment base 2 is installed and fixed through the notches 23 , thereby achieving installation and fixation of the entire bearing seat body 1 .

[0040] Among them, the height position of the bearing seat body 1 is adjustable. When the multiple sets of locking nuts 22 are loosened, the bearing seat body 1 can slide axially along the stud 21. At this time, the height position of the bearing seat body 1 can be adjusted. After the adjustment is completed, tighten the multiple sets of locking nuts 22 and retighten them. This improves the flexibility of the bearing seat body 1 during use and is suitable for a variety of installation environments.

[0041] Finally, it should be noted that: Obviously, the above embodiments are only examples for clearly explaining the present invention, and are not intended to limit the implementation methods. For ordinary technicians in the relevant field, other different forms of changes or modifications can be made based on the above description.
