Problems solved by technology
[0005] The purpose of the present invention is to provide a multi-stage ring groove processing method and inspection device, aiming to solve the problem that the labyrinth seal ring groove of the medium-pressure end seal cover in the prior art is an angled ring groove and the groove width is very narrow. The wall is very thin. It is difficult to process the sealing ring groove by using the ordinary axial and radial method of processing the ring groove. Because the groove width is too narrow, the general measuring tool cannot realize the technical problem of measurement.

The invention relates to the technical field, in particular to a multi-stage ring groove machining method and inspection device.The multi-stage ring groove machining method comprises the following steps that a marking tool is used for marking a machining part of a sealing cover; lathe equipment is used for removing redundant parts of the large end and the small end of the sealing cover; lathe equipment is used for removing the redundant allowance part of the reference end face; machining an unmachined datum plane end, an outer circle and an end face sealing ring groove of the sealing cover; lathe equipment is used for finish turning of the large end face and the ring groove of the sealing cover through an inner ring groove cutter and an end face groove cutter; drawing a center line on the small end face of the sealing cover by using a vernier caliper; the large cross section of the sealing cover faces upwards, a lineation and a step outer circle are aligned, all holes are machined, and redundant allowance is removed through rough turning; and finally, a labyrinth sealing ring groove of the large end and the inner hole is machined by adopting a one-time forming cutter, and then the groove width is measured by using a measuring rod, so that the deformation is reduced, and the dimensional tolerance requirement of the inner hole, the jumping requirement of the inner hole relative to the reference surface and the parallelism requirement are ensured.
Description
technical field [0001] The invention relates to the technical field, in particular to a processing method and inspection device for a multi-stage ring groove. Background technique [0002] At present, the marine turbocharger is used as a supporting part of the diesel engine, and the pressure end seal cover is a part of the product of this model, and the labyrinth seal ring groove on the end face and the inner hole plays an indispensable role. A throttling gap and an expansion cavity are formed between the annular sealing teeth on the sealing cover and the annular sealing teeth on the compressor impeller, and the sealed medium will produce a throttling effect when passing through the gap of the labyrinth to achieve the purpose of leak prevention and seal. [0003] Since the labyrinth seal has no solid-phase friction, does not require lubrication, and allows thermal expansion, it is suitable for high temperature, high pressure, and high speed frequency occasions. It is widely ...
