Cleaning device and method for deep hole of engine cylinder block

Abstract

The invention relates to a cleaning device and method for a deep hole of en engine cylinder block. The cleaning device comprises a connecting pipe, a compressed air pump, a nylon sand feeding device and a cleaning device, and a joint is arranged at one end of the connecting pipe; an outlet pipe of the compressed air pump is connected with a blowing pipe; the nylon sand feeding device comprises a feeding pipe and a storage tank, and the feeding pipe is connected with the connecting pipe and the blowing pipe; nylon sand is stored in the storage tank, and an outlet pipe of the storage tank is connected with the feeding pipe; the cleaning device comprises a cleaning fluid tank, a flushing water tank and a high-pressure water pump, and the cleaning fluid tank and the flushing water tank are connected with an inlet pipeline of the high-pressure water pump; and an outlet of the high-pressure water pump communicates with the blowing pipe. The device is not limited by the depth and shape of a porous channel, compressed air is used for driving the nylon sand to collide and grind burrs left in an engine oil duct hole; the residual burrs in the deep hole are effectively removed, and impuritiesin the engine oil duct hole are thoroughly cleaned up through high-pressure spraying, so that the assembly precision of the engine cylinder block is improved; and the performance of the engine is improved, and the service life of the engine is prolonged.

Description

technical field [0001] The invention relates to the technical field of engine block processing, in particular to an engine block deep hole cleaning device and method. Background technique [0002] With the development of engine manufacturing technology, the production efficiency of the engine is getting higher and higher. During the processing of the engine block, the dust and impurities attached to the upper surface of the engine block and the iron cuts generated during processing will enter the oil in the engine block. In deep holes such as oil passage holes, these dust and iron cuts will affect the machining accuracy of the oil passage holes of the engine block. Therefore, the engine block must be cleaned before and after processing. At present, the oil passage holes of the engine block It mainly adopts high-pressure spraying and ultrasonic combined application. [0003] However, when the engine block is being processed, some burrs often remain in the deep holes of the o...

Problems solved by technology

[0003] However, when the engine block is being processed, some burrs often remain in the deep holes of the oil channel holes of the engine block. The existing cleaning cannot completely remove the burrs in these deep holes, and the remaining burrs will affect the assembly of the engine block Accuracy, which in turn has a certain impact on the performance and service life of the engine
