Problems solved by technology
[0002] This part belongs to the cylinder block of the automobile air-conditioning compressor. The conventional machining method is to process the two sides separately. It is difficult to ensure the parallelism and coaxiality of the two processing surfaces, which may easily cause the piston to be seized when the compressor is working.

Embodiment Construction
[0018] The present invention will be described in detail below with reference to the accompanying drawings and in combination with embodiments.
[0019] A method for processing a single-cylinder body of an air-conditioning compressor, characterized in that:
[0020] Step 1. Incoming material inspection, according to the product rough drawing, inspect the machining size allowance is sufficient, the positioning size is qualified, the positioning surface is flat, and there are no casting defects such as lack of material cracks;
[0021] Step 2. Finish turning two planes and boring middle holes at all levels, and process them on a CNC lathe. The positioning references of subsequent processes are all concentrated in this process, and the clamping is completed in one process. The end face of the inner cavity is used for positioning, and the 6 claws clamp the blank piston hole to ensure that Φ99 The coaxiality with Φ26 is 0.025, T01 and T07 are two counter knives added after improvem...

The invention discloses a processing method of a single-cylinder body of an air conditioner compressor, which comprises the following steps of: feeding and checking; finish turning two planes and boring each stage of intermediate hole; centralizing all datum references of subsequent work procedures in the work procedure and finishing the all datum references by one-step clamping; drilling and milling various holes on a large plane, positioning according to a bottom plane and a large hole of a lathe, limiting a blank pin hole and pressing an upper end surface; drilling and milling each hole on a concave plane, positioning according to a bottom plane, an intermediate hole and a pin hole and pressing an upper-end pin surface; milling a window, positioning according to the bottom plane, the intermediate hole and the pin hole and pressing the upper-end pin surface; milling an oil groove, positioning according to the bottom plane, the intermediate hole and the pin hole and pressing the upper-end pin surface; boring a piston hole and positioning according to the bottom plane, the intermediate hole and the pin hole and pressing the upper-end pin surface; inspecting a finished product; and packaging and warehousing. According to the processing method for processing all datum references by one-time clamping and ensuring the stability of the references, which is provided by the invention, the processing capability and efficiency are improved; the processing quality is ensured; the subsequent feeding yield is greatly improved; and the production cost is reduced.
Description
technical field [0001] The invention relates to a machining method, in particular to a machining method for a single-cylinder body of an air-conditioning compressor. Background technique [0002] This part belongs to the cylinder block of the automobile air-conditioning compressor. The conventional machining method is to process the two sides separately. It is difficult to ensure the parallelism and coaxiality of the two machining surfaces, and it is easy to cause the piston to seize when the compressor is working. Contents of the invention [0003] The purpose of the present invention is to provide a machining method that processes all the positioning datums in one clamping and ensures the stability of the datums. [0004] In order to achieve the above-mentioned technical purpose and achieve the above-mentioned technical effect, the present invention is realized through the following technical solutions: [0005] A single-cylinder processing method for an air-conditionin...
