[0021] In order to better explain the present invention and facilitate understanding, the present invention is described in detail below through specific implementation modes in conjunction with the accompanying drawings.

[0022] Please refer to Figure 1 to Figure 2 A balancing weight device based on an air-conditioning compressor includes a balancing block 1 and a washer 2 both made by powder metallurgy. At least two guide columns 3 are arranged at the bottom of the balancing block 1, and a docking hole 4 corresponding to the guide column 3 is opened on the washer 2.

[0023] Wherein, the balancing weight 1 is made of stainless steel or high manganese steel, and the washer 2 is made of stainless steel or high manganese steel.

[0024] The washer 2 is an annular structure, the balancing weight 1 is an arc structure, and the inner wall of the balancing weight 1 overlaps with the inner wall of the washer 2 in vertical projection;

[0025] The powder metallurgy industry has certain limitations, and some structures cannot be formed in one time, so two blanks are produced for combined superposition sintering. The balancing block 1 and the washer 2 are both produced by powder metallurgy. The balancing block 1 is provided with two guide columns 3, and the washer 2 is also provided with a matching docking hole 4 at the corresponding position, and then superposition sintering is carried out. The balancing block 1 and the washer 2 are produced using stainless steel or high manganese steel with a high shrinkage rate. A certain proportion of sintering activator is added to the powder. The principle of powder metallurgy sintering is to utilize the low melting point and high surface energy characteristics of metal powder, and sinter at a certain temperature to combine the powder particles to form a dense material.

[0026] The balancing block 1 and the washer 2 formed by powder metallurgy are combined by setting the guide column 3 and the docking hole 4, and then sintered to realize the integration of the balancing block 1 and the washer 2. Not only can the balancing block 1 and the washer 2 be directly assembled, but the washer 2 formed by powder metallurgy has lower cost and is suitable for large-scale promotion and use.

[0027] The circuits, electronic components and modules involved are all prior art and can be fully implemented by those skilled in the art. Needless to say, the content protected by this utility model does not involve improvements to software and methods.

[0028] The above are only embodiments of the present invention, and are not intended to limit the patent scope of the present invention. Any equivalent transformations made using the contents of the specification and drawings of the present invention, or directly or indirectly applied in related technical fields, are also included in the patent protection scope of the present invention.

[0029] In addition, it should be understood that although the present specification is described according to implementation modes, not every implementation mode contains only one independent technical solution. This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment may also be appropriately combined to form other implementation modes that can be understood by those skilled in the art.
