Compressor assembly process

Abstract

The invention provides a compressor assembly process which comprises an eccentric distance detection step. The eccentric distance detection step comprises the following steps of controlling a crankshaft of a transmission assembly to rotate, and detecting the eccentric distance of a movable disc of the transmission assembly. The movable disc of the transmission assembly is connected with one end of the crankshaft of the transmission assembly. In order to reduce compression leakage and guarantee smoothness and stability of rotation of the movable disc, the eccentric distance of the movable disc should be within a reasonable range. According to the compressor assembly process provided by the invention, in the eccentric distance detection step, when the crankshaft of the transmission assembly is controlled to rotate, the eccentric distance of the movable disc of the transmission assembly is detected, namely, the eccentric distance of the movable disc is detected before a static disc is assembled, so that the situation that when measurement on the compression leakage amount is not qualified after the whole compressor is assembled, the eccentric distance of the movable disc can be adjusted only by disassembling the static disc, and time and labor are wasted is avoided. The compressor assembly process provided by the invention is high in production efficiency, low in production cost and capable of meeting the requirement for batch production. A compressor product adopting the compressor assembly process provided by the invention is high in assembly precision and excellent in quality.

Description

technical field [0001] The invention relates to the technical field of compressors, in particular to a compressor assembly process. Background technique [0002] The oil-free scroll compressor uses a pair of phase-staggered spirals to move with each other to form a compression chamber that shrinks continuously from the outside to the inside to achieve airflow compression. During the working process of suction, compression and exhaust, the static disk is fixed on the frame, and the movable disk is driven by the crankshaft and controlled by an anti-rotation mechanism, and swings in a plane with a small radius around the center of the base circle of the static disk. The difference from conventional reciprocating rotary compressors is that the relative movement gap between the two spirals of the oil-free scroll compressor is small but does not touch, and the linear velocity of the relative motion of the two spirals is relatively low. According to the above principles, the oil-f...

Problems solved by technology

However, in the existing compressor assembly process, there is no step of detecting the eccentricity of the moving plate, and the measurement of the compression leakage can only be carried out after the compressor products are completely assembled.

Once the compression leakage does not meet the requirements, the eccentricity of the moving disk needs to be adjusted. However, at this time, the moving disk is located inside the compressor product, and the static disk assembly needs to be disassembled to adjust the eccentricity of the moving disk, which is time-consuming and laborious.

Moreover, the crankshaft can no longer be taken out from the machine base. If you need to adjust the eccentricity of the moving disc by adjusting the eccentricity of the crankshaft, you can only adjust the eccentricity of the crankshaft manually, and manual alignment is a technical job, which is time-consuming and laborious.

It can be seen that the adjustment of the eccentricity of the moving plate has become a bottleneck problem affecting the mass production of compressors, which in turn reduces the assembly accuracy requirements of compressor products, resulting in instability between the mechanical components of compressor products during operation. As a result, the overall operating noise of the compressor increases, which affects the performance of the product
