A self-centering two-way rotating cross-axis machining spindle

Abstract

The invention discloses a self-centering bidirectional rotating cross shaft machining main shaft in the technical field of precision machining equipment. The self-centering bidirectional rotating cross shaft machining main shaft comprises a device shell, a rotating oil cylinder mechanism, a lifting mechanism, clamping reversing mechanisms, positioning mechanisms and a speed reducing motor, whereina bearing fixing sleeve and a pair of angular contact bearings are fixedly attached to an inner cavity of the device shell; the lifting mechanism is arranged in an inner cavity of the rotating oil cylinder mechanism; the lifting mechanism comprises a lifting frame body and two lifting installation blocks; the clamping reversing mechanisms is provided with two groups symmetrical at up and down; the two groups of clamping reversing mechanisms clamp and fix a cross shaft workpiece by mutually approaching; the positioning mechanism is provided with two groups which symmetrical at back and forth and are respectively embedded on the front side and the back side of the lifting frame body and used for positioning two opposite shaft ends in the cross shaft workpiece; and the speed reducing motor is embedded below the device shell and used for driving the rotating oil cylinder mechanism to rotate. The self-centering bidirectional rotating cross shaft machining main shaft is used for machining the cross shaft workpiece.

Description

technical field [0001] The invention relates to the technical field of precision machining equipment, in particular to a self-centering bidirectional rotating cross axis machining spindle. Background technique [0002] With the development of modern science and technology, the level of mechanical processing and manufacturing technology has improved. Machining accuracy determines product quality and has become one of the standards for measuring an industrial level. Machining accuracy is the relationship between the actual size, shape and position of the surface of the processed part. The degree of compliance with the ideal geometric parameters required by the drawings. The ideal geometric parameters, in terms of size, are the average size; in terms of surface geometry, they are absolute circles, cylinders, planes, cones and straight lines, etc.; in terms of mutual positions between surfaces, they are absolute parallelism , vertical, coaxial, symmetrical, etc. The deviation ...

AI Technical Summary

Problems solved by technology

[0004] 1. Only one of the end holes 102 can be processed at a time, and four times of clamping are required to process a cross-axis workpiece 10, which is cumbersome and inefficient;

[0005] 2. Due to the defects described in 1., the coaxial accuracy of the two aligned end holes 102 in the cross-axis workpiece 10 cannot be guaranteed

[0006] 3. Rely on machine tool equipment for processing. When mass production and processing, at least one machine tool equipment must be specially equipped for processing. The purchase price of machine tool equipment is generally high, which does not conform to the concept of high-efficiency development of modern enterprises
