Technical Field

[0001] The invention relates to the technical field of compressor manufacturing, and in particular to a compressor piston precision hole processing device. Background Art

[0002] In the field of compressor manufacturing, the piston is one of the core components, and the processing quality of its fine hole is directly related to the overall performance and service life of the compressor; especially when using materials such as graphite gray cast iron, due to its unique physical and chemical properties, such as good castability, vibration damping, wear resistance and excellent machinability, it becomes the preferred material for compressor piston manufacturing; but due to the material characteristics of graphite gray cast iron and the limitations of processing technology, a series of problems often occur during the processing; first, the stability of processing data is difficult to guarantee, which is mainly caused by factors such as material inhomogeneity and thermal deformation during cutting; second, the shape and dimensional accuracy of the fine hole are difficult to control, and problems such as fine hole out of roundness and dimensional tolerance often occur; these problems not only seriously affect the energy efficiency and reliability of the compressor, but also greatly increase the manufacturing cost and scrap rate;

[0003] At present, the commonly used processing method in the industry is to use a blade tool to make a preliminary opening of the piston hole, and then process the hole diameter in place through subsequent processing steps; however, this processing method has obvious disadvantages; on the one hand, it is often difficult to ensure that the connection between the opening and the subsequent fine hole is smooth and has no dead angle during the preliminary opening, which not only affects the overall shape and dimensional accuracy of the fine hole, but may also cause problems such as stress concentration; on the other hand, the high temperature and chips generated during the processing are difficult to be removed in a timely and effective manner, which further aggravates the deterioration of processing errors and surface quality;

[0004] Therefore, in response to the above problems, the present invention proposes a new compressor piston fine hole processing device; the device ensures the stability and accuracy of the processing process by accurately controlling the position, rotation speed and feed rate of the tool and optimizing the fixing method of the fixture; at the same time, cooling and cleaning are performed during fine hole processing to effectively deal with the high temperature and chip problems generated during the processing.
