Technical Field

[0001] The utility model relates to the technical field of bearing processing devices, in particular to a grease adding device used between a bearing spot welding sheet and an oil seal cover. Background Art

[0002] In mechanical structures, bearings are key components, and their lubrication condition has a crucial impact on the operating efficiency, stability, and service life of the mechanical structure. In the narrow space between the bearing spot weld and the oil seal cover, bearing lubrication is mostly achieved by manually adding grease. However, due to the subjectivity and uncertainty of manual operation, the amount of grease added each time can vary significantly, resulting in inconsistent bearing lubrication results and making it difficult to ensure that the grease is evenly distributed in the areas that require lubrication. Relying on manual filling is not only time-consuming and labor-intensive, but also increases production and labor costs. Therefore, it is particularly important to develop a device that is simple in structure, easy to operate, low in cost, and capable of accurately adding grease. Utility Model Content

The port 32 connects the accommodating chamber 31 with the outside world; an oil delivery pipe 7 is provided at the oil outlet of the grease metering pump 2, and the other end of the oil delivery pipe 7 is connected to the oil filling port 32; a grease head 4 is provided on the upper side of the fixed block 3, and an oil storage hole 41 is provided at the bottom of the grease head 4, and a bearing placement groove 42 for placing the bearing 11 is provided at the upper end of the grease head 4, and a plurality of first oil holes 44 are provided on the inner side wall of the bearing placement groove 42 along the circumferential direction, and a second oil hole 45 corresponding to the first oil hole 44 is provided at the top of the oil storage hole 41 along the circumferential direction. When grease flows into the oil storage hole 41, it will be evenly distributed between the spot welding sheet and the oil seal cover of the bearing through the second oil hole 45 and the first oil hole 44, thereby improving the lubrication effect of the bearing.

[0024] In this embodiment, if Figure 4 As shown, a protrusion 33 is provided on the upper end of the fixing block 3 , and a through hole 34 is provided in the middle of the protrusion 33 to connect the accommodating cavity 31 with the oil storage hole 41 .
