[0002] Gas compressors are used in many industries of the national economy. The diameter of the final stage cylinder of the general high-pressure compressor and the ordinary cylinder of the very small displacement compressor is very small, usually below Φ20mm, but the axial length is relatively large, and The surface roughness and shape tolerance requirements of the inner surface of the cylinder are very high. In order to facilitate maintenance, the form of a cylinder liner is often used. However, for the processing of such precision parts, the traditional processing method requires the use of various special machine tools, fixtures, tools, and equipment investment. Large, high scrap rate

Embodiment Construction
[0015] The present invention will be further described below in conjunction with the accompanying drawings.
[0016] like figure 1 , figure 2 , image 3 It can be seen that the present invention provides a special device for processing small-diameter cylinder liners, including a lathe with a three-jaw chuck 1, a clamp 4, a lathe tip 6 and a lathe slide box tool rest 7, and also includes a three-jaw chuck 1 and the tool bar 2 between the top 6 of the lathe, the tool bar 2 is provided with a tool head 5 .
[0017] Using the above device to process the cylinder liner is divided into three steps:
[0018] The first step is to turn the outer circle; turn the outer circle of the workpiece 3 and drill the inner hole to leave an appropriate margin for the subsequent finishing process.
[0019] The second step is inner hole turning; put the tool bar 2 with the tool head 5 through the workpiece 3 and put it into the three-jaw chuck 1 of the lathe, and the other end is supported by ...

The invention provides small-diameter air cylinder sleeve machining technology and a dedicated device of the small-diameter air cylinder sleeve machining technology. The small-diameter air cylinder sleeve machining technology and the dedicated device of the small-diameter air cylinder sleeve machining technology are simple in technology condition, low in manufacture cost, low in rate of wasted product and wide in machining range. The dedicated device comprises a three-claw clamp disc, a clamp, a lathe center, a lathe of a knife rest of a lathe sliding box and a knife rod arranged between the three-claw clamp disc and the lathe center. A knife head is arranged on the knife rod. A front guiding knife head is arranged on the knife rod. The front guiding knife head is longer than the knife head along the radial direction of the knife rod. The front guiding knife head is arranged before the knife head along a walking direction of the knife rest of the lathe sliding box. Three machines steps are included. Firstly, an outer circle is turned. Secondly, an inner hole is ground. Thirdly, an inner hole is ground and cut.
Description
technical field [0001] The invention relates to a mechanical processing technology, in particular to a small hole cylinder liner processing technology. Background technique [0002] Gas compressors are used in many industries of the national economy.
