Abstract
The invention discloses a York cylinder sleeve and a processing method thereof. A product comprises a cylinder-sleeve boss end surface, wherein the surface roughness of the cylinder-sleeve boss end surface is 0.2 mu m, and the flatness of the cylinder-sleeve boss end surface is 8 mu m. The processing method is a method combining grinding and hand lapping. The method disclosed by the invention is simple and reliable, and not only is the production efficiency improved, but also the quality of the end surface is ensured. The requirements that the roughness is lower than 0.3 mu m is met by the product, and meanwhile, the requirements that the upper limit of the flatness is 10 mu m is met.
Description
Technical field
The present invention relates to the processing method of a kind of York cylinder sleeve.
Background technique
York cylinder sleeve is to use on the compressor of central air-conditioner, and it is the heart of compressor, but the working principle of it and internal combustion engine cylinder jacket is different.Internal-combustion engine does not have high requirement to the planeness of cylindrical boss end face, roughness, and General Requirements is: planeness 30-50 μ m; Roughness 6.3-3.2 μ m.By general processing method, just can guarantee.York cylinder sleeve is different, and the planeness of cylindrical boss end face, roughness have high requirement: the planeness upper limit 10 μ m; The roughness upper limit 0.3 μ m.Because its end face is sealing surface, do not allowed any defect, adopt conventional method difficult processing to meet the demands.
Summary of the invention
The object of the present invention is to provide a kind of good York cylinder sleeve and processing method thereof of surface roughness, planeness performance of cylindrical boss end face.
Technical solution of the present invention is:
A York cylinder sleeve, comprises cylindrical boss end face, it is characterized in that: the surface roughness <0.2 μ m of cylindrical boss end face, planeness <8 μ m.
A processing method for York cylinder sleeve, comprises the processing of cylindrical boss end face, it is characterized in that: the processing of cylindrical boss end face comprises the following steps: successively
(1) York cylinder sleeve is placed in the identical fixture of shape and York cylinder sleeve, the supporting shoulder lower plane of York cylinder sleeve is bearing in the top planes of fixture, the location cylindrical of York cylinder sleeve contacts with the top inner circle of fixture, supporting shoulder and location cylindrical by York cylinder sleeve position, and by the electromagnetic force that surface grinding machine worktable produces, clamp;
(2) adopt the green carbon granule wheel of 46 order numbers to carry out grinding, emery wheel diamond pen is selected natural diamond material; During grinding, the first grinding capacity according to 0.02mm/ time carries out grinding repeatedly, and the grinding capacity of last 1 ~ 2 time is 0.005mm/ time, extremely without machining allowance;
(3) adopting the marble of extra fine grade dull and stereotyped, select W28(01) abrasive paper for metallograph of order number carries out hand lapping to end face, to surface roughness <0.2 μ m, the planeness <8 μ m of cylindrical boss end face.
Grinding allowance before grinding is controlled at 0.01mm.
The inventive method is simple, reliable, has not only improved manufacturing efficiency but also guaranteed end face quality.Product has met the requirement of roughness lower than 0.3 μ m, has met the requirement of the planeness upper limit 10 μ m simultaneously.
