Abstract

The invention discloses a rotor machining machine tool for a single screw compressor. The machine tool comprises a machine tool body provided with a stand column and horizontal guide rails. Vertical guide rails are arranged on the stand column. A tool rest table is mounted on the horizontal guide rails. A screw workpiece clamping mechanism is mounted on the vertical guide rails. A tool is mountedon the tool rest table and can be driven to make front-back movement, left-right movement and rotary movement in the horizontal direction. A to-be-machined screw workpiece is mounted on the screw workpiece clamping mechanism, the axis of the screw workpiece is arranged horizontally and the screw workpiece is clamped tightly through the screw workpiece clamping mechanism, and the screw workpiece clamping mechanism can drive the screw workpiece to move up and down in the vertical direction and also can drive the screw workpiece to rotate continuously around the axis. A turning tool or a millingtool is adopted as the tool. By means of the machine tool provided by the invention, envelope strength line, envelope cylinder and other complex molded line single screw compressor screw toothed grooves can be machined, operation is easy, and the precision and the speed are high.

Description

technical field

[0001] The invention belongs to the field of mechanical processing, and in particular relates to a rotor processing machine tool for a single-screw compressor. Background technique

[0002] Single-screw compressors have the advantages of simple structure, small size, light weight, and low vibration and noise, and are widely used in military, aerospace, petrochemical, air-conditioning, refrigeration, food and other industries. The screw and the star wheel are the core components of the single screw compressor, and the screw tooth groove and the star wheel blade are also the most difficult parts in the processing of the single screw compressor parts.

[0003] The traditional method of machining screw tooth grooves is to use a tool to simulate the movement between the star gear teeth and the screw tooth groove. When processing in this way, the tool and the feeding mechanism (such as a stepping motor) need to be installed on a rotary table . Since the feed mech...
