A positioning device for installing a fuel injector on a diesel engine, including a cylinder head installed on a cylinder, a number of fuel injectors are arranged on the cylinder head, an oil inlet arm is formed on the fuel injector, and a positioning baffle is arranged on the cylinder head , the positioning baffle is composed of a cross bar, a vertical rod and a stopper. A number of vertical rods are formed on the crossbar. The top of the vertical rod is formed with a stopper extending to the side of the crossbar. The side wall of the stopper is formed with a slope , the oil inlet arm of the injector leans against the slope of the positioning baffle, pin holes are formed at both ends of the cross bar, and the positioning pins pass through the pin holes of the cross bar and are plugged into the cylinder head; The fuel injector is fixed on the cylinder head through the injector pressure plate and the fuel injector pressure plate bolts. It uses a new type of positioning device to position the fuel injector and then fasten it, so that the installation angle of the fuel injector can be accurately positioned, which facilitates the installation of the cylinder head cover, and also solves the problem of sealing rings in the four holes on the side of the cylinder head cover risk of oil spills.

The invention provides an adjustable oil receiving plate device and a control method thereof, belonging to the technical field of mechanical lubrication. In the present invention, a reversible oil receiving plate is arranged in the box of the reducer, and the oil receiving plate is connected to the driver electrically connected to the controller through a cable, and the oil receiving plate is provided with an oil receiving plate extending to the oil groove of the box body. The oil collecting groove and the oil passage hole with flange make it possible to control the driver to lower the oil receiving plate through the cable when the controller detects the low speed operation of the reducer, and receive the lubricating fluid brought by the gear through the oil receiving plate. After the oil is collected by the oil collecting groove, it flows into the oil groove of the box to realize the lubrication of the bearing. When the controller detects that the gearbox is running at a high speed, it can control the driver to pull the oil receiving plate through the cable to reduce or avoid the oil receiving plate. The collection of lubricating oil can prevent the risk of oil leakage caused by excessive lubricating oil and accumulation on the oil seal, which can not only realize the lubrication of the bearing, but also reduce the oil level of the lubricating oil, reduce the sealing pressure, and reduce the risk of oil leakage.

The invention relates to a pulley of an intelligent variable valve adjusting device and a preparation method thereof, belonging to the field of auto parts. The adjustment device pulley includes a pulley (1), an oil pump base plate (2) and an oil pump body (3), the oil pump base plate (2) and the pulley (1) adopt an integrated design, and the oil pump body (3) It is directly connected with the belt pulley (1) by connecting bolts (4); the powder metallurgy material used for the belt pulley (1), oil pump bottom plate (2) and oil pump pump body (3) is: FC-0205-40. The method is as follows: treating the pulley of the powder metallurgy intelligent variable valve adjusting device with water vapor at 550°C±50°C for 2h±0.5h. The material and manufacturing costs of the invention are relatively low.

The present invention belongs to the field of electronic cigarette technology, and has disclosed an oil cup oil leakage structure and electronic cigarettes.The oil leak -proof structure of the oil cup includes the oil cup component and the atomized core, which includes the oil cup component, the positioning ring fixed on the opening of the oil cup, and the oil seal placed inside the oil cup body, the internal oil cup body bodyWith the first flue gas channel, the positioning of the inner wall of the ring is equipped with a ring -shaped first convex. The first raised upper set is equipped with a stop ring made of elastic materials. One end of the oil seal is equipped with the first protrusions.The second raised and the other end is the second flue gas channel extending to the first flue gas channel. The first flue gas channel and the second flue gas channel are seal settings;EssenceIn the process of moving the oil leak -proof structure of the invention, and the electronic cigarettes in the motion of the atomized core and oil seal, it can ensure that the oil in the oil cup's body is always sealed and effectively prevent the risk of oil leakage.

The invention relates to the field of hydraulic drive systems, in particular to a variable stiffness joint hydraulic drive system for an exoskeleton robot, comprising a left leg variable stiffness joint drive system and a right leg respectively used to drive a left leg and a right leg and have the same internal structure Variable stiffness joint drive system, the drive system includes a hydraulic power module and a joint drive module that assists driving the human body to walk. The invention uses a distributed power source to replace the centralized hydraulic power source in the exoskeleton backpack, and solves the problem of the centralized hydraulic power source. and the risk of oil leakage caused by many oil pipe joints, reducing the complexity of system control, and decomposing the centralized hydraulic power source into distributed hydraulic power sources, which can replace the load-bearing backpack often found in hydraulically driven lower extremity exoskeletons. Backpacking makes the overall structure more concise.
