Embodiment Construction

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

[0035] like figure 1 Shown, the present invention has designed a kind of processing method of automobile air-conditioning compressor double-cylinder body, is characterized in that comprising the steps:

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

[0037] Step (2): Machining the large surface of the finish car and boring the middle holes at all levels on the CNC lathe, specifically including the following processes:

[0038] Step (21): On the CNC lathe, the large plane of the front cylinder body of the finish car is processed by clamping the rough piston hole and the inner cavity surface for close positioning;

[0039] St...

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 edge of the cylinder body, artificially creating two rear parts, and the hot nodes mentioned in the casting. , so that the gradual and unable 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 its casting is also uneven. The part that is supported from the sprue is insufficiently fed, resulting in shrinkage porosity. [0003] The requi...
