[0002] The balance block is a counterweight component, and its function is to keep the high-speed rotating mechanism in dynamic balance. For compressors, the balance block is an important part of the compressor rotor. The center of gravity of the crankshaft that rotates with the rotor does not coincide with the center of rotation, so when the crankshaft rotates at high speed in the compressor, dynamic imbalance will occur. The balance block is installed on the upper end of the rotor to balance, reduce noise and dampen vibration. With the continuous development of science and technology, people have higher and higher requirements for the manufacturing process of the balance block of air-conditioning compressors.

[0003] The existing air-conditioning compressor balance block has certain disadvantages when in use. First, the existing compressor balance block has a relatively simple structure and cannot be assembled conveniently and quickly. It is not suitable for more models of compressors and is not conducive to people's use. In addition, the structural strength of the existing air-conditioning compressor balance block cannot meet the requirements well, which brings certain adverse effects to the actual use process. For this reason, we propose a multi-piece riveted air-conditioning compressor balance block. Utility Model Content
