Description

Flatness positioning tool for side mounting lug of compressor cylinder cover Technical Field The utility model belongs to the technical field of compressor production, and particularly relates to a flatness positioning tool for a side mounting lug of a compressor cylinder cover. Background In a process of tightening a cylinder head by a compressor complete machine, since a restriction to a cylinder block is lacking during a tightening operation, a positional deviation of the cylinder block is liable to occur during the period, and thus quality problems of unacceptable flatness are caused, so that it is necessary to add a flatness detecting process. However, when the flatness of the whole machine is detected, the whole machine is screwed up firstly, an operator takes the compressor out of the line after screwing up, an out-of-line flatness detection tool is used for detecting the flatness of the whole machine, and when the flatness is detected to be different, a rubber hammer is used for beating the mounting surface of the whole machine, so that the flatness is qualified.
