Special scroll machining machine tool and machining method thereof

Abstract

The invention discloses a special scroll machining machine tool and a machining method thereof. The special scroll machining machine tool comprises a base, a spindle module, a workbench module, an automatic tool changing module and a cooling lubrication module, wherein the spindle module, the workbench module, the automatic tool changing module and the cooling lubrication module are arranged on the base. The machining movement mechanism of the special scroll machining machine tool is that an electric spindle drives a tool to rotate at a high speed, tool cutting-in feed is achieved through Z-axis servo, a workbench DD motor drives a workpiece to do rotary motion, workpiece radial feed movement is achieved through X-axis servo feed of the workbench DD motor, a polar coordinate motion interpolation track is achieved through the combination of the above two motions, and the mode is the optimal movement mode for scroll spiral line machining; a film hydraulic operated clamp or a film pneumatic clamp is used for workpiece clamping, and high-precision clamping and positioning are achieved; and the high precision and high efficiency requirements for scroll plate machining are achieved through the special scroll machining machine tool and the machining method thereof.

Description

technical field [0001] The invention relates to a special machine tool for scroll processing and a processing method thereof, in particular to the processing of thin-walled spiral scrolls in scroll compressors. Background technique [0002] A scroll compressor is a volumetric compression compressor, and the compression components are composed of a moving scroll and a static scroll. A number of structural features are included to allow for a shunt flow of gas through the compressor casing to reduce oil entrainment. [0003] After entering the casing, some of the gas flows upward to reduce the amount of gas flowing downward towards the oil. To achieve this, the motor of the compressor may be surrounded by a sleeve having upper and lower holes for directing air flow to the upper and lower stator end turns of the motor. In some embodiments, it is important to position the suction inlet relative to the two gas passages between the stator and the motor housing. The inlet is pos...

Problems solved by technology

Due to the complex shape of the helical surface of the vortex, the error generated by this processing method when passing the quadrant can easily cause strip defects on the processed surface, so follow-up inspection and finishing are required to make up for the processing defects and meet the use requirements.
