Quantitative grease injection device for automobile sunvisor rotating mechanism

Abstract

The invention relates to a quantitative grease injection device for an automobile sunvisor rotating mechanism. The device comprises a grease barrel (1), a grease pump (2), a bracket (3), a quantitative valve (6) and a control switch (8) which are fixed on the bracket (3), and an injection head (7) which is connected with the outlet of the quantitative valve (6), wherein the inlet of the grease pump (2) is communicated with the grease barrel (1), and the outlet of the grease pump (2) is communicated with the inlet of the quantitative valve (6); and the quantitative valve (6) is connected with the control switch (8). Compared with the prior art, the device has the advantages that: the device can quantitatively and uniformly inject grease at a fixed position, so that uniform grease is left between a rotating shaft and the inner wall of a fixing clip, a sunvisor is flexible, stable and noiseless and has high rotating durability during operation, yield is improved, the labor intensity of workers is reduced, and production cost is reduced.

Description

Technical field: [0001] The invention relates to a grease quantitative filling device for a rotating mechanism of an automobile sun visor. Background technique: [0002] At present, the car sun visor assembly is a suspended moving part installed on the upper crossbeam of the front windshield to provide the front seat occupants with the function of blocking sunlight and anti-dazzling. Due to the requirements of durable use and rotation, it is necessary to quantitatively and evenly add lubricating grease to the friction damping mechanism of the rotating mechanism (in the fixed clip) during manufacture. But the grease of the rotating mechanism of the automobile sun visor of the prior art is all manually filled by hand. Specifically, the workman takes out the grease from the storage bucket through a quantitative spoon, and wipes the grease on the opening of one end of the fixing clip, and then puts the grease on the opening of the fixing clip. The rotating shaft is inserted int...

But the grease of the rotating mechanism of the automobile sun visor of the prior art is all manually filled by hand. Specifically, the workman takes out the grease from the storage bucket through a quantitative spoon, and wipes the grease on the opening of one end of the fixing clip, and then puts the grease on the opening of the fixing clip. The rotating shaft is inserted into the fixing clip from the opening where the fixing clip is smeared with grease, but this method of grease filling has the following problems: First, the front end of the rotating shaft is very easy to push the grease from the opening at one end of the fixing clip to the bottom of the fixing clip The opening of the other end, so that there is no grease or less grease between the rotating shaft and the inner wall of the fixing clip, resulting in cumbersome, sluggish, loud noise and poor rotation durability when the sun visor is operated, and the yield rate is low. Low; secondly, the amount of grease added should be greater than the theoretical amount of grease (the theoretical amount is 2±0.5g), generally 3-8g of grease is required, otherwise the amount of grease left between the rotating shaft and the inner wall of the fixing clip less, which increases the production cost; moreover, the manual operation is labor-intensive, and this method simply cannot achieve quantitative, positioning and uniform grease filling
