Description

Technical Field

[0001] The utility model belongs to the technical field of automobile parts, and in particular relates to a mechanism for applying lubricating grease to a small door gear of an automobile charger. Background Art

[0002] With the continuous development of new energy vehicles, many parts of traditional fuel vehicles have been optimized and upgraded to cater to the experience of end consumers. Among them, the automatic charging port cover is upgraded and evolved on the basis of the fuel tank cover of traditional fuel vehicles. Compared with the fuel tank cover, the charging port cover is more often used by consumers for charging. In order to allow users to have a better user experience when charging, the opening and closing process of the charging port door is required to be smooth and free of jamming. The principle of opening the charging port door is that the motor drives the gear and the crank arm shaft to rotate, thereby driving the small door on the crank arm to rotate, so as to achieve the opening and closing state of the small door. In order to ensure that the small door can maintain smooth movement during long-term use, the gear mechanism as the core rotating component needs to be pre-coated with a certain amount of grease. The existing coating is usually carried out manually, but the worker's operating efficiency is low and cannot meet the needs of high-efficiency work. Although the vertical glue injection machine improves efficiency, this method cannot accurately apply to the root between the gears, which will cause the grease to slip easily, resulting in poor coating effect. How to quickly and effectively pre-coat grease at the gear mechanism of the charging small door has become a technical problem that needs to be solved at present. Utility Model Content

[0019] In order to make the purpose, technical solutions and advantages of the present invention more clear, the following Figure 1-Figure 4It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0020] The utility model proposes a mechanism for applying grease to a car charging wicket gear, comprising a base plate 1, and a clamping assembly arranged on the base plate 1, a gear rotating assembly 2 for rotating the car charging wicket gear is arranged on one side of the base plate 1, and a grease pre-coating assembly 3 is arranged on the other side of the base plate 1. In this embodiment, the gear rotating assembly 2 and the grease pre-coating assembly 3 are respectively arranged on the adjacent two sides of the base plate. A contouring jig 4 for placing a product 6 is arranged on the base plate 1, and a clamping assembly 5 for clamping the product is placed on the contouring jig. The clamping assembly 5 can be a clamping cylinder.

[0021] The gear rotating assembly 2 includes a gear center joint 26 that matches the charging wicket gear. The gear center joint 26 is arranged opposite to the charging wicket gear and is used to extend into the gear center to form a connection with the gear and then drive it to rotate. The grease injection end of the grease pre-coating assembly 3 faces the charging wicket gear. Specifically, the gear rotating assembly 2 includes a first bracket 21 vertically arranged on the base plate 1, and an upper and lower cylinder 22 is arranged horizontally and vertically on the first bracket 21. A slide rail 23 is arranged on one side of the first bracket 21, and a slider 24 is arranged on the slide rail 23. A rotating motor 25 is connected to the slider 24. The gear center joint 26 is connected to the motor shaft of the rotating motor, and the slider 24 is connected to the upper and lower cylinders 22. The upper and lower cylinders 22 drive the slider 24 to reciprocate up and down on the slide rail 23, and the rotating motor 25 drives the gear center joint 26 to rotate.

[0022] In this embodiment, the product 6 is placed under the rotating motor, that is, the upper and lower cylinders 22 drive the rotating motor 25 to reciprocate up and down in the direction of the product's gear. For better control accuracy, the upper and lower cylinders 22 are servo cylinders, and the rotating motor 25 is a rotating servo motor. And both are electrically connected to the PLC system.

[0023] The grease pre-coating assembly 3 includes a fixed bracket 31 vertically arranged on the bottom plate, a driving cylinder 33 is arranged on the fixed bracket 31, an oil injection metering valve 32 is connected to the driving cylinder 33, and one end of the oil injection metering valve 32 is connected to an oil injection needle 321. The oil outlet end of the oil injection needle 321 is arranged obliquely above the gear to be filled with oil. The driving cylinder 33 drives the oil injection metering valve 32 to move toward the product gear, and at the same time, the oil injection needle 321 can be driven to enter the root of the gear, so that the grease is well bonded to the gear wall and is not easy to fall off, so as to ensure that the product is lubricated and reduces resistance and friction during long-term use.

[0024] The gear rotating assembly 2 cooperates with the grease pre-coating assembly 3 to ensure that each tooth root of the gear can be effectively oiled once.

[0025] In order to better detect whether there is any leakage during the filling of lubricating oil, a detection component 7 is also provided on the bottom plate. The detection component 7 is an image acquisition mechanism provided on the bottom plate through a bracket.

[0026] The device of the utility model can accurately control the rotation of gears and the amount of oil injection, so that the overall formation is automated, avoiding manual oiling, and also avoiding the situation where grease slips due to the inaccurate oiling of direct oiling by a glue injection machine, and has strong practicality.
