Embodiment Construction

[0020] Below in conjunction with accompanying drawing and specific embodiment this scheme is described further:

[0021] The high-precision CNC rotor grinding machine described in this plan is mainly composed of a bed 1, a worktable 10, a headstock 2, a tailstock 11, a grinding wheel frame 5, a precision abrasive tool, and a grinding wheel dressing device 6. The bed 1 is the basic part of the machine tool, used to support other main components of the machine tool, and is equipped with a linear transmission device for the longitudinal movement of the workbench 10 . The headstock 2 and tailstock 11 are installed on the workbench 10, and the workpiece is supported by a special fixture between the headstock 2 and the tailstock 11, and the rotation of the headstock 2 drives the workpiece to rotate to complete the rotation required for the rotor grinding process. sports. The grinding wheel frame 5 is located at the rear of the machine tool bed 1, and the grinding wheel and the prec...

Abstract

The invention discloses a high-precision numerically-controlled rotor grinding machine which comprises such components as a machine body, a workbench, a head frame, a tail frame, a grinding wheel rack, a precision grinding tool and a grinding wheel mechanism; the machine body adopts a numerically-controlled forming grinding method, a mathematical model that the motion trail of a trimming roller is conjugate with a forming surface is established, and the movement of two shafts of a grinding wheel dresser is controlled through a numerical control device to enable the arc center of a diamond roller to generate linkage in two coordinate directions, and the grinding wheel is dressed into a required forming surface. During processing, the grinding wheel is fully contacted with the outline of a workpiece, and numerically-controlled forming grinding is realized by utilizing lengthwise movement of the workbench, precision indexing movement and transverse feeding movement of the grinding wheel, so that a rotor can be ground into a required shape. The high-precision numerically-controlled rotor grinding machine has the advantages that the grinding profile accuracy reaches 0.01 mm, the tooth surface roughness can be Ra 0.2 to 0.32, the production efficiency is increased by at least two times compared with that of the traditional milling process, and the processing cost is reduced greatly compared with that of milling.

Description

technical field [0001] The invention relates to the field of metal cutting machine tools, in particular to a high-precision numerically controlled rotor grinder, which is a device for processing complex helicoidal rotors. Background technique [0002] Special-shaped screw rotors are widely used in mechanical equipment in mining, chemical industry, power, metallurgy, construction, machinery, refrigeration, light industry and other industries. The tooth surfaces of these parts have different shapes, high precision requirements, and relatively difficult processing. Among them, the Screw compressors, refrigerators, and industrial pumps have the highest precision requirements for screw rotors and are the most representative. [0003] Take the screw compressor as an example: the most important part of the screw compressor is a pair of helical female and male rotors that mesh with each other. The gap, the gap between the rotor tooth top and the inner hole of the casing, is guarant...
