Embodiment 1
[0032] The method for remanufacturing the main bearing hole of the engine cylinder block assembly comprises the following steps:
[0033] (1) Machining of the joint surface of the main bearing seat of the cylinder block: Based on the joint surface of the main bearing seat of the cylinder block, use a surface grinder and tooling grinding to remove the processing amount of 0.02mm on the joint surface of the main bearing seat of the cylinder block, and ensure that the cylinder The shape and position tolerance requirements of the joint surface of the body main bearing seat;
[0034] (2) Machining of the joint surface of the main bearing seat of the crankcase: taking the joint surface of the main bearing seat of the crankcase as the benchmark, use a surface grinder and tooling to grind the joint surface of the main bearing seat of the crankcase to remove the processing amount of 0.02mm;
[0035] (3) Assembly: Assemble the cylinder block and crankcase according to the assembly seque...
Embodiment 2
[0038] The method for remanufacturing the main bearing hole of the engine cylinder block assembly comprises the following steps:
[0039](1) Machining of the joint surface of the main bearing seat of the cylinder block: Based on the joint surface of the main bearing seat of the cylinder block, use a surface grinder and tooling grinding to remove the processing amount of 0.05mm on the joint surface of the main bearing seat of the cylinder block, and ensure that the cylinder The shape and position tolerance requirements of the joint surface of the body main bearing seat;
[0040] (2) Machining of the joint surface of the main bearing seat of the crankcase: taking the joint surface of the main bearing seat of the crankcase as a reference, the machining amount of 0.05mm is removed by surface grinder and tooling grinding on the joint surface of the main bearing seat of the crankcase;
[0041] (3) Assembly: Assemble the cylinder block and crankcase according to the assembly sequence...
