Description

Technical Field

[0001] This utility model relates to the field of workpiece processing technology, specifically to a semi-automatic quantitative grease injection and dust cover assembly integrated equipment for workpieces such as shafts and sleeves. Background Technology

[0002] Currently, the grease injection and dust cover assembly of workpieces mainly rely on manual operation.

[0003] In the grease injection process: workers manually inject grease around the workpiece using a hand-held grease gun, manually controlling the amount and speed of grease injection. This results in poor grease uniformity (circumferential deviation ≥15%) and low quantitative accuracy (single injection volume deviation ±8%), directly causing unstable lubrication performance of the workpiece and a product acceptance rate of less than 80%.

[0004] Dust cover assembly process: Workers manually open the dust cover and put it on the workpiece. Repeated opening and closing can easily lead to elastic fatigue of the dust cover, with a crack rate as high as 12%. The one-time assembly rate is less than 75%, and cracks will cause the dust cover to fail to seal, shortening the product's service life by more than 25%.

[0005] Production efficiency and safety: Manual operation per person per shift is only 300 pieces, with high labor intensity (repetitive actions ≥5000 times per day), which can easily cause wrist and lumbar spine injuries to workers, and cannot meet the capacity requirements of mass production (daily demand ≥1000 pieces).

[0006] Currently, there is no integrated equipment on the market that can simultaneously solve the problems of "quantitative and uniform grease injection" and "low-crack assembly dust cover". These issues have become key bottlenecks restricting the improvement of quality and efficiency in the workpiece processing industry. Utility Model Content
