Example Embodiment

[0034] Below in conjunction with accompanying drawing, the technical scheme of the present invention is described in further detail:

[0035] like figure 1 As shown, the present invention designs a processing method for the double cylinder block of an automobile air-conditioning compressor, which is characterized by comprising the following steps:

[0036] Step (1): Inspect the front cylinder and rear cylinder according to the product blank drawing to ensure that each processing size allowance is sufficient, the positioning size is qualified, the positioning surface is flat and there is no missing material crack;

[0037] Step (2): Machining the finishing plane and boring medium holes at all levels on the CNC lathe, including the following treatments:

[0038] Step (21): On the CNC lathe, the large plane of the front cylinder block of the finishing turning is processed by the method of clamping the blank piston hole and the inner cavity surface closely and positioning;

Abstract

The invention discloses a machining method for the double cylinder bodies of an automobile air-conditioning compressor, characterized by comprising the following steps of: performing incoming inspection, finely finishing a large plane and boring each stage of centre holes, finely finishing a concave surface, drilling and milling each hole of the concave surface, drilling and milling each hole of the large plane, assembling and carving a serial number, milling a window, boring a piston hole, performing finished product inspection, packaging warehousing. The machining method for the double cylinder bodies of an automobile air-conditioning compressor disclosed by the invention can ensure the demand-satisfying coaxiality of the bearing holes and the piston holes of the machined double cylinder bodies, that is, the front and rear cylinder bodies, of the automobile air-conditioning compressor.

Description

technical field [0001] The invention relates to a processing method for a double-cylinder body of an automobile air-conditioning compressor. Background technique [0002] In the prior art, pressure casting is used for both the front and rear cylinders. This method uses molds to manufacture, but there are the following problems. The two pouring ports are on the outer side of the cylinder body, artificially creating two rear parts, and the hot node mentioned in the casting. It makes gradual and impossible to achieve balanced solidification, and can not achieve sequential solidification. It is easy to form conveying and pinholes inside the cylinder. Since the position of the gate is far away from the position of the five cylinder holes, the pressure of multiple cylinder holes in die casting is inconsistent. The unlocking ability of casting is also not balanced. The part that is supported from the sprue is insufficiently fed, resulting in shrinkage porosity. [0003] The requi...
