Problems solved by technology

[0005] In actual production, there is a phenomenon of misalignment of the mounting holes, including the misalignment of the mounting holes caused by the processing of the parts and the misalignment of the mounting holes caused by the cooperation of the parts during the assembly of the pump body, which makes the pump body off the assembly line and the pump body is reassembled, resulting in the assembly pass rate of the pump body. Low, the assembly efficiency of the pump body is low

Embodiment Construction

[0046] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0047] In order to facilitate the understanding of the pump body structure of the rotary compressor provided by the present invention, the terms are explained as follows:

[0048] Centering: After the pump body parts are placed according to the position, the process of realizing the gap between the cylinder, the crankshaft and the rollers meets the design requirements by adjusting the small displacement between the pump body parts.

[0049] Centering: After th...

Abstract

The invention discloses a rotatable compressor and a pump body structure thereof. The pump body structure comprises a first assembly which is centered and cored, a first partition plate, and a second assembly which is centered, wherein the second assembly and the first partition plate are cored with the first assembly; the first assembly is provided with a coring threaded hole; the second assembly is provided with a second coring through hole and a third coring through hole which are opposite to the coring threaded hole, and a second centering through hole and a second centering threaded hole which are opposite to the coring threaded hole; the first partition plate is provided with a fourth coring through hole opposite to the coring threaded hole; {min(D22, D23, D24)-M21}-(D1B-M12) is greater than or equal to 0.2 mm and less than or equal to 1.0 mm, wherein D12 is the aperture of the second centering through hole, D22 is the aperture of the second coring through hole, D23 is the aperture of the third coring through hole, D24 is the aperture of the fourth coring through hole, M12 is the threaded diameter of the second centering threaded hole, and M21 is the threaded diameter of the coring threaded hole. According to the pump body structure, the assembling qualification rate and the assembling efficiency are improved.

Description

technical field [0001] The invention relates to the technical field of pump body assembly of a rotary compressor, and more specifically, relates to a rotary compressor and a pump body structure thereof. Background technique [0002] Rotary compressors are widely used due to their high compression efficiency, small size, light weight, low noise, and low power consumption, especially in the fields of refrigerators and air conditioners. [0003] The rotary compressor mainly includes: a casing, a driving motor and a pump body, wherein the pump body includes several parts, such as an upper flange, a lower flange, and a cylinder. The assembly method of the pump body of the rotary compressor is centering first and then centering. Specifically, centering is to place the parts of the pump body according to the position, and then adjust the small displacement between the parts, and realize the alignment between the cylinder and the crankshaft through the centering screw. The gap betw...
