Description

Vortex compressor assembly precision gauge

Technical Field

Background

In the prior scroll compressor manufacturing process, the perpendicularity of a crankshaft and an upper support and a lower support is one of the most critical assembly dimensions. Poor perpendicularity of the crankshaft and the upper and lower supports directly affects the performance of the compressor and indirectly causes abnormal clearance between the stator and the rotor of the compressor motor. When the compressor runs, if the clearance between the stator and the rotor of the motor is abnormal, the motor can cause the problems of chamber sweeping, ignition and the like, and the potential safety hazard is great. Currently used verticality detection tools are generally divided into two types, but dial indicators are used as main measuring tools: the first type is to use an integrated gauge for inspection, and the second type is to use a measuring part and a rotary driving mechanism split gauge for inspection.

The prior art has the following defects: because the first type of gauge adopts an integrated structure, the measurement accuracy can be influenced in the process of checking by rotating the gauge by an operator, and the application is less. The second type of gauge usually adopts a mode that a magnetic seat adsorbs a crankshaft to fix a measuring part, and the fixing mode has two defects: firstly, the magnetic seat can make the bent axle be magnetized and the magnetic seat bottom often adsorbs there is tiny iron fillings unable clean up, and this just makes the bent axle absorption after the magnetic seat bottom iron fillings probably be by magnetism and brings into inside the compressor, and the foreign matter of mixing can cause the unusual wearing and tearing of compressor and finally leads to the compressor to damage: secondly, because the magnetic seat itself has limited adsorption force, the operator can cause the displacement of the detection part to distort the detection result due to the false collision in the detection process. Meanwhile, the conventional detection tool and detection method have the problems of complex operation, low detection efficiency, limited detection precision by the technical level of operators and the like.

Aiming at the problems in the prior art, the novel vortex compressor assembly precision gauge is researched and designed, so that the problems in the prior art are overcome.
