Description

Technical Field

[0001] The utility model relates to the technical field of oil pump component assembly, in particular to an oil filter tightening machine used in an oil pump assembly production line. Background Art

[0002] When the engine is working, the oil pump works continuously to ensure that the oil continues to circulate in the lubrication oil circuit. Under various engine operating conditions, the oil pump should ensure that sufficient lubrication oil is supplied; the engine oil itself contains a certain amount of colloid, impurities, water and additives. If the engine oil enters the lubrication oil circuit directly without being filtered, the impurities contained in the engine oil will be brought into the friction surface of the moving pair, accelerating the wear of parts and reducing the service life of the engine; therefore, the oil pump needs to be used in conjunction with the oil filter to filter out debris, colloid and water in the engine oil to deliver clean engine oil to each lubrication part.

[0003] In the prior art, when assembling the oil filter of the automobile oil pump, the bolts are tightened manually. This method is easily interfered by human factors, has low efficiency, and the degree of tightening of the bolts by manual operation is different, which affects the precision quality of the automobile oil pump bolt assembly.
