Connect the connector between said eccentric shaft and said guide pillar drive end, make the descending free degree of guide pillar restrained, thereby form support guide pillar;
Wherein, eccentric shaft axis and guide pillar axis quadrature, the change of eccentric shaft radial is reflected on the moving up and down of guide pillar so.
Theory according to cam mechanism can know that eccentric shaft is a kind of theoretic cam, and curve movement is very simple, is convenient to the conversion of angle of eccentricity and guide pillar displacement.
It is higher pair that the kinematic pair core of cam mechanism constitutes, and reduces the use of higher pair in this programme as much as possible, certainly; Also generally adopt various forms to reduce the use of higher pair in the cam mechanism; Connector is used for the conversion of lower pair higher pair as the transition driving member, designs seldom also little.Preferable selection is shown in accompanying drawing 2; Said connector is the corresponding slide block 13 that is connected to said guide pillar drive end and eccentric shaft side in two ends about in the of; So; The plane can be made in the guide pillar lower surface, is matched with the smooth slide block in upper end, and the version of coupling eccentric shaft side curved surface then can be made in the slide block lower end.
About the driving of eccentric shaft, can adopt the handwheel of with locking mechanism to adjust, configuration scale, convenient adjustment intuitively.For the ease of realizing automation; Preferable selection is the structure shown in accompanying drawing 4; Comprise that also one drives the reducing motor 3 of said eccentric shaft through driving-chain; And be engaged in said eccentric shaft detecting the sensor of its position, and the controller that connects this sensor and the said reducing motor of output control, constitute closed-loop control system.Because the adjustment of guide pillar, even available adjustment only need eccentric shaft rotate one week half cycle, therefore, need reducing motor that enough big speed reducing ratio is arranged, output speed is low as much as possible, can obtain than higher driving precision
Cooperate closed-loop control, further acquisition drives precision preferably.
Selection of Sensor can be selected the higher rotary encoder of price, is applied to the detection of meeting rotating shaft.Preferable selection is to adopt lower-cost sensor, the linear displacement transducer 9 shown in accompanying drawing 2, and precision can meet the demands, and cost can significantly reduce.So accordingly, said sensor is the sensor that contains the rectilinear motion measuring staff, the axes intersect of the axis of corresponding measuring staff and said eccentric shaft wherein, and engage with said eccentric shaft 6 through a mover 8.Sensor is fixed on the support 4 through fixed cell 7.
About the selection of driving-chain, the mounting means of the eccentric shaft of consideration can be selected adaptive driving-chain, contains the self adaptation part, and like flexible axle, but the transmission accuracy of flexible axle is poor.Therefore; Preferable selection is that said driving-chain comprises a universal drive shaft 14, in other words universal joint/Hooks coupling universal coupling, the removable coupling components of this universal drive shaft power shaft of connection and said reducing motor output shaft simultaneously; Easy access; Carry out manual adjustment after perhaps taking apart, manual adjustment can also be characterized by the zeroing verification, the selection of feedback reference point.
Because above-mentioned connected two parts all are axle type parts, so corresponding, said removable coupling components is one to connect lock sleeve, and is simple in structure, and the connection of rigidity can guarantee the precision of transmission, and what yielding coupling was tried one's best avoids the use of.
In order to obtain reasonable installing space, said sensor with the eccentric shaft be reference measuring point radially with the abutment of guide pillar quadrature radially, simultaneously; Because the curve movement of eccentric shaft is fairly simple; The variation of mounting structure, little to the influence of calculating, especially under the condition that quadrature is installed.
