Abstract

The invention discloses a milling machine used for processing single-screw compressor rotors, comprising a machine body, a vertical column and a mill support device which are arranged on the machine body, wherein, the vertical column is connected with a workpiece rotary chuck and a device which leads the workpiece rotary chuck to vertically move along the z-direction; the workpiece rotary chuck is connected with a transmission mechanism which leads the workpiece rotary chuck to rotate around the x-axis; the milling machine is characterized in that the mill support device comprises a mill seat and a mill axes arranged on the mill seat and used for mounting the mill, and a base arranged in a horizontal guideway along the y-direction of the machine body; the base is provided with a chassis rotated by the linking to the workpiece chuck; two translation mechanisms which lead the mill seat to horizontally move in the x-direction and the y-direction respectively are arranged between the mill seat and the chassis, and a rotation mechanism which leads the mill support to rotate along the x-y plane; the mill support is provided with a mill driver which leads the mill axes to rotate. The special mill machine of the invention has the advantages of high processing speed and processing precision, and can produce high-precision single-screw compressor engaged channel pairs.

Description

technical field [0001] The invention relates to mechanical processing equipment, in particular to a milling machine for processing screw rotors of single screw compressors. Background technique [0002] Compressors are widely used in railways, ships, mines, construction, chemicals, textiles, metallurgical machinery, military instruments, ships and other industries. Compared with reciprocating compressors and twin-screw compressors, single-screw compressors have the advantages of simple structure, reliable operation, small size, light weight, and low noise. [0003] There are more than ten companies in France, Japan, Britain, the United States, the Netherlands and other countries that can produce single-screw compressors abroad. In recent years, some manufacturers in my country have also begun to produce single-screw compressors, but their performance indicators are generally lower than imported products. Especially in the case of using the same material, the service life of...
