Abstract

The invention discloses an eccentric mechanism capable of achieving continuous amplitude adjustment in motion. The eccentric mechanism comprises a driving shaft, an inclined shaft, a shaft sleeve and an inclined sleeve; the driving shaft comprises a left half shaft and a right half shaft which share one axis, the inclined shaft is connected between the left half shaft and the right half shaft, the axis of the inclined shaft crosses with the axis of the driving shaft, and the included angle alpha between the inclined shaft and the driving shaft is 1 degree to 15 degrees; an inclined through hole is formed in the inclined sleeve, and the inclined shaft penetrates the inclined through hole and can slide along the inclined through hole; the shaft sleeve is rotationally connected to the inclined sleeve; and the driving shaft is driven by a driving mechanism and can slide in the axial direction of the driving shaft. By means of the technical scheme, even though the driving shaft is in the rotation state, the driving mechanism can drive a sliding plate to further drive a main shaft to slide in the axial direction of the driving shaft, and therefore the driving shaft drives the inclined shaft to move to generate relative displacement with respect to the inclined sleeve, the eccentric distance a is adjusted, the aim of adjusting the distance of up-and-down reciprocating motion of the shaft sleeve in real time is achieved, and the problem that a traditional eccentric mechanism cannot achieve continuous amplitude adjustment in motion is solved.

Description

technical field [0001] The invention relates to an eccentric mechanism, in particular to an eccentric mechanism capable of continuously adjusting the range during motion. Background technique [0002] As a mechanical structure, the eccentric mechanism is widely used in many industries because of its simple structure and strong operability. Most of the eccentric mechanisms in the prior art are of fixed amplitude, such as the crankshaft; there are also some mechanisms with adjustable amplitude, but because the power shaft is rotating, it is impossible to install a real-time adjustable mechanism to adjust the eccentric amplitude in real time. The operating range is adjusted by adjusting the eccentric distance when the operation is stopped, so it is impossible to realize the real-time adjustment of the eccentric range during the movement of the eccentric mechanism, and it cannot meet the needs of the equipment for amplitude adjustment during operation. Announcement No. 54 of 20...
