Abstract

The invention provides an ultrafine equipment oscillation mechanism comprising a rotary driving device and an oscillator seat arranged outside a rotary shaft of the rotary driving device coaxially ina sleeving mode. The ultrafine equipment oscillation mechanism further comprises an amplitude adjusting assembly and an oscillator longitudinal pin. The rotary driving device is utilized for driving the rotary shaft amplitude adjusting assembly to rotate synchronously, the oscillator longitudinal pin oscillates in a reciprocating fixed-amplitude mode in the vertical direction in the oscillator seat through intermittent contact of the amplitude adjusting assembly and the matching end of the oscillator longitudinal pin, and adjustable amplitude and oscillation frequency of the oscillation mechanism are achieved by adjusting the contact distance of an amplitude assembly and the matching end and the quantity of convex parts while the technical problem of insufficient stability of the oscillation mechanism is solved.

Description

technical field [0001] The invention relates to the technical field of oscillating mechanical structures on superfinishing equipment, in particular to an oscillating mechanism for superfinishing equipment. Background technique [0002] At present, the oilstone oscillation method commonly used in superfinishing machines is to convert the rotation of ordinary AC motors into reciprocating oscillations of swing mechanisms through space mechanisms. Although the oscillation frequency can be changed by changing the speed of ordinary AC motors, this structure borrows Regarding the output of the conversion mechanism, due to the relationship between the inertia and the transmission path, there is a large deviation between the actual output oscillation frequency and oscillation amplitude and the preset oscillation frequency and oscillation amplitude. Machining accuracy needs further improvement. [0003] For example, in the patent document with the patent number CN201110296398.4 (here...
