TECHNICAL FIELD
[0001] The utility model relates to a compressor technical field especially relates to a scroll compressor dynamic disc phosphating turnover basket. BACKGROUND
[0002] As a kind of efficient, low noise and compact structure compression equipment, scroll compressor plays an important role in many fields. It realizes the continuous compression of gas through a pair of each other precision meshing static disc and dynamic disc, not only provides smooth operating characteristics and higher energy efficiency ratio, and since the few moving parts, significantly reduce operating noise and vibration, enhance the reliability and service life of equipment. Therefore, scroll compressor is widely used in household and commercial air conditioning systems, refrigeration equipment, automobile air conditioner and industrial gas compression and other fields, become indispensable key components in modern refrigeration and air handling technology.
[0003] In scroll compressor, dynamic disc is one of the core components to realize gas compression, and its design and manufacturing precision directly determines the overall performance of compressor. Dynamic disc is mainly composed of base plate and the scroll line and bearing hole on both sides thereof. Scroll line is located on the side of base plate, can be accurately matched with the scroll line on static disc, forms a series of continuously changing working chamber, to realize the effective compression of gas. Bearing hole is located on the other side of base plate, for installing driving shaft or connecting to the power source of compressor, ensure that dynamic disc can carry out eccentric rotation movement smoothly. Generally, in order to facilitate installation, reduce weight and optimize the balance of dynamic disc, process groove is usually set on the peripheral surface of base plate, which not only helps to improve the machining efficiency and assembly accuracy in manufacturing process, but also can effectively reduce stress concentration, prolong the service life of dynamic disc.
[0004] In the machining process of the orbiting scroll, in order to improve the oil storage and wear resistance of the orbiting scroll, the surface of the finish machined surface of the orbiting scroll is often subjected to surface phosphating treatment. Phosphating refers to forming a phosphate protective film on the surface of the metal through chemical reaction to enhance the corrosion resistance of the workpiece, improve the adhesion of the coating and improve the wear resistance and other properties. For the orbiting scroll of the scroll compressor, the phosphating quality directly affects the service life and operating efficiency. In the prior art, the orbiting scroll phosphating usually uses a turnover basket for loading and fixing. The current turnover basket design has the following problems: (1) first, the existing turnover basket design often needs to be in direct contact with the two side surfaces of the base plate, the outer circle of the bearing hole or the side wall of the outer circle of the scroll line to ensure the fixing effect, which is easy to cause the abnormal phenomenon of phosphating iron leakage in the contact part of the orbiting scroll and the turnover basket, which affects the uniformity and integrity of the phosphating, and further reduces the overall phosphating quality of the orbiting scroll; (2) secondly, since the scroll line on the orbiting scroll forms many compression cavities with large depth, and the existing turnover basket is usually opened downward or in a horizontal position when in use, air is easy to accumulate in the cavity during phosphating treatment, so that the local area cannot be fully contacted with the phosphating liquid, which also causes the phosphating iron leakage problem, affecting the overall phosphating quality of the orbiting scroll. Since the two side surfaces of the base plate, the outer circle of the bearing hole, the side wall of the outer circle of the scroll line and the compression cavity formed by the scroll line are important parts in the assembly and operation of the orbiting scroll, the phosphating iron leakage problem at the above positions directly reduces the production quality of the orbiting scroll, affects the smooth operation of the orbiting scroll and reduces the service life of the orbiting scroll.
