Embodiment Construction

[0030] The present invention will be further described below through the description of specific embodiments with reference to the accompanying drawings.

[0031] The specific implementation is shown in Figures 1 to 4.

[0032] An eccentric shaft with adjustable eccentricity mainly used for processing thin-walled eccentric sleeve workpieces, comprising a mandrel body 1, one side of the mandrel body 1 has a shaft shoulder 1-1, and the other side has an external thread section 1- 2. The external thread section 1-2 is set with a washer 9 and a lock nut 10 that can be screwed with the external thread; the two ends of the mandrel body 1 are respectively provided with symmetrical multi-edged through holes 1-3 along the radial direction; The prismatic through hole 1-3 is provided with a locking block 5 that is fitted and slidable; the two axial ends of the mandrel body 1 are respectively provided with symmetrical wedge-shaped sliding blocks that communicate with the multi-primed thro...

Abstract

An eccentric axle with adjustable eccentricity for machining the thin-wall sleeve barrel is composed of a core axle body and an eccentricity adjusting block with two central holes at it's both ends and matched with the head and tail centers of machine-tool. Said eccentricity can be adjusted by adjusting the distance between the central axis of said core axle body and the central hole of said eccentricity adjusting block.

Description

technical field [0001] The invention relates to an eccentric shaft with adjustable eccentric distance, which belongs to the mechanical manufacturing technology. Background technique [0002] The eccentric shaft involved in the present invention is a process equipment for machining eccentric thin-walled sleeve workpieces. [0003] The eccentric workpiece mentioned in conventional processing is processed by replacing the eccentric shaft with different eccentric distances. That is to say, workpieces with unequal diameter inner holes and different eccentric distances need to be processed with eccentric shafts with different outer diameters and different eccentricities. For the adjustment of the eccentricity of the eccentric sleeve workpiece processed by the non-eccentric shaft, the conventional method is to adjust the eccentricity within a certain range through an eccentric adjustment mechanism composed of eccentric gears and / or eccentric cams. As a result of the above-mention...
