Embodiment 1

[0029] In this embodiment, the two-cylinder compressor includes two sliding vanes, two pistons, two cylinders, one crankshaft, one main bearing, and one auxiliary bearing.

[0030] There is a partition 1 between the two cylinders, such as figure 1 As shown, the separator 1 is in the shape of a disk with a thickness of 9 mm, and a through hole 2 with a diameter of 30 mm is provided in the center of the disk for passing the crankshaft, and the diameter of the disk is 80 mm. In addition, installation through holes are provided on the partition 1, including five first through holes 3 with a diameter of 10 mm and two second through holes 4 with a diameter of 7 mm.

[0031] In this embodiment, a solid steel rod is used, and the steel rod has a cylindrical structure with a cross-sectional diameter of 80 mm. Through the cutting process, the cutting direction is perpendicular to the length direction of the steel bar, and a steel blank with a thickness of 3 mm is cut from the steel bar...

Embodiment 2

[0033] In this embodiment, the structure of the partition in the double-cylinder compressor is exactly the same as that in Embodiment 1.

[0034] In this embodiment, a hollow steel rod is used. The steel rod has a hollow cylindrical structure, and its cross section is a ring with an outer diameter of 80 mm and an inner diameter of 30 mm. Through the cutting process, the cutting direction is perpendicular to the length direction of the steel rod, and a steel blank with a thickness of 9 mm is cut from the steel rod. Then, a cutting piece with through holes 2, five first through holes 3, and two second through holes 4 is made on the steel blank by laser cutting, that is, as figure 1 separator shown.

Embodiment 3

[0036] In this embodiment, the two-cylinder compressor includes two sliding vanes, two pistons, two cylinders, one crankshaft, one main bearing, and one auxiliary bearing.

[0037] There is a partition 1 between the two cylinders, such as figure 2 As shown, the separator 1 is in the shape of a disk with a thickness of 15 mm, and a through hole 2 with a diameter of 30 mm is provided in the center of the disk for passing the crankshaft, and the diameter of the disk is 80 mm. The edge of the disc is in concave structure 5 . In addition, installation through holes are provided on the partition 1 , including five first through holes 3 with a diameter of 10 mm and two second through holes 4 with a diameter of 7 mm.

[0038] In this embodiment, a solid steel rod is used, and the steel rod has a cylindrical structure with a cross-sectional diameter of 80 mm. By cutting, the cutting direction is perpendicular to the length direction of the steel bar, and a steel blank with a thickne...

Abstract

The invention provides a manufacturing method of a partition plate in a multi-cylinder compressor. The partition plate is located between two adjacent air cylinders and provided with a through hole for penetrating of a crankshaft. The partition plate is manufactured by using a steel bar and carrying out a cutting process. According to the method, the process is simple and efficient, the cost is low, environment-friendly and pollution-free effects are achieved, and the overall strength, hardness and dimensional precision of the partition plate can be guaranteed.

Description

technical field [0001] The invention relates to the technical field of compressors, in particular to a method for manufacturing a partition in a multi-cylinder compressor. Background technique [0002] Rotary refrigeration compressors are widely used in air conditioners such as households because of their high refrigeration efficiency, compact structure, small size, and light weight. [0003] The compression assembly is an important part of the rotary refrigeration compressor, mainly including the cylinder, piston, vane, crankshaft, main bearing and auxiliary bearing. The multi-cylinder compressor includes at least two cylinders, each cylinder has a compression chamber, a partition is arranged between two adjacent cylinders, and a through hole is formed on the partition to allow the crankshaft to pass through. [0004] At present, the separator is generally made by a casting process or a powder metallurgy process. [0005] The casting process is generally a process in whic...
