Problems solved by technology

Such a connection method, on the one hand, is more complicated to operate, on the other hand, the solder joint itself cannot guarantee the connection strength between the upper cylinder head and the casing, and the upper cylinder head and the casing may still be separated from each other due to external force

Abstract

The invention provides a compressor and a manufacturing method of an upper cylinder head of the compressor. The compressor includes a shell with the inner surface of the shell being provided with at least one groove surrounding the inner circumference of the shell, a motor assembly, a compression assembly which is placed in the shell and includes an upper cylinder head, a cylinder and a lower cylinder head, and a crankshaft, wherein the cylinder is arranged between the upper cylinder head and the lower cylinder head, the outer surface of the upper cylinder head is provided with at least one protrusion surrounding the outer circumference of the upper cylinder head, and the protrusions correspond to the grooves and are embedded in the corresponding grooves. The invention provides a technicalscheme for enhancing the connection strength between the upper cylinder head and the shell. The inside of the shell is provided with the grooves. When molten metal is poured into an upper cylinder head mold inside the shell, the protrusions matching the grooves are formed. The physical connection at combination parts between the shell and the upper cylinder head is increased through the protrusions and the grooves so as to enhance the strength of connection and fixing. Therefore, the shell and the upper cylinder head can be prevented from being disconnected due to force, and the product yieldis increased.

Description

Technical field [0001] The present invention relates to the technical field of compressors, and in particular to a compressor that enhances the connection strength of an upper cylinder head and a casing and a method for manufacturing an upper cylinder head of the compressor. Background technique [0002] Such as figure 1 Shown is a schematic structural diagram of a compressor with an integrated upper cylinder head and casing in the prior art. The compressor includes a housing 101, a motor assembly 102, a crankshaft 103, and a compression assembly. The motor assembly 102, the crankshaft 103, and the compression assembly are all arranged inside the housing 101. The compression assembly includes an upper part arranged in order from top to bottom. The cylinder head 104, the cylinder 105 and the lower cylinder head 106, and the crankshaft 103 transmit the rotational force of the motor assembly 102 to the piston inside the cylinder 105 to perform a compression operation. [0003] Among ...
