Compressor cylinder block machining method

Abstract

The invention discloses a compressor cylinder block machining method. The compressor cylinder block machining method is characterized in that a cylinder block comprises a cylinder head, a cylinder face, a cylinder hole used for containing a piston and a shaft hole used for containing a crankshaft, and the cylinder head is provided with a blocking mechanism used for blocking the torque of a screw from being transmitted to the cylinder hole. the cylinder block machining method comprises the steps that a, the cylinder block is cast; b, the blocking mechanism is machined; c, starting checking is conducted, wherein a positioning clamp and a combined machine tool are checked before starting, and the cylinder block is clamped on the clamp; d, a cylinder hole, a shaft hole and a cylinder hole spigot are bored in the cylinder block; e, the cylinder block is blanked from the combined machine tool; f, honing of the cylinder hole and the shaft hole is conducted; and g, brushing, cleaning and demagnetizing are conducted. The blocking mechanism is arranged and can prevent the torque of the screw from being transmitted to the cylinder hole from a compressor cylinder cover, and the problem of deformation of the cylinder hole due to the transmission of the torque of the screw of the compressor cylinder cover to the cylinder hole can be solved.

Description

technical field

[0001] The invention belongs to the technical field of compressor manufacturing, and in particular relates to a method for processing a compressor cylinder block. Background technique

[0002] At present, the cylinder block of the compressor is mainly made of gray cast iron. During the casting process of gray cast iron, due to the flow and cooling of molten iron, and the presence of ferrite and flake graphite in the cast iron, there are certain differences in the strength of different parts of the cast iron. , especially when the cylinder head screws are fastened, there is a certain deformation in the cylinder head. The deformed cylinder seat will cause changes in the roundness and cylindricity of the cylinder bore of the cylinder seat, affect the fit clearance between the piston and the cylinder bore, and even cause compression Even if there is no jamming, during the actual operation of the refrigeration system, due to the deformation of the cylinder bore an...
