Description

Technical Field

[0001] The utility model relates to the technical field of press-fitting machines, in particular to a plugging cover press-fitting machine used for assembling an oil pump. Background Art

[0002] The oil pump pressurizes the oil in the oil pan and sends it to the oil filter and various lubricating oil channels to lubricate the main moving parts of the engine and filter the oil. When the oil pump is produced and processed, the various components need to be assembled together.

[0003] During the manufacturing process of the oil pump, the plug cap needs to be assembled to the preset position on the pump body. Traditional plug cap installation generally adopts manual assembly, that is, the operator relies on a simple press rod to resist the plug cap, and then manually hammers the press rod to press the plug cap to the corresponding position. There are the following problems with manual press-fitting of the plug cap: inaccurate positioning during the press-fitting process causes the plug cap in the cylinder body to be pressed off-center, and also causes the plug cap hole to deform, making it difficult for the oil pump to rotate and affecting the engine lubrication; the operator's hand directly contacts the punch part of the press rod, which is easy to be crushed and there is a safety hazard; because the matching method between the cylinder body and the plug cap is interference fit, the required press-fitting force is large, the labor intensity is high, and the production efficiency is low.
