Detailed description of the invention
Below in conjunction with the accompanying drawings this utility model is described further.
As depicted in figs. 1 and 2, this eccentric includes hydraulic pump 2, clamping cylinder 6 and support cylinder 9；The oil-out of hydraulic pump 2 is communicated with an overflow valve 3, and the oil-out of hydraulic pump 2 simultaneously and is connected to 2/2-way solenoid directional control valve 4 and the oil-in of two four-way electromagnetic reversing valves 5；
The rodless cavity of the oil-out connection support cylinder 9 of 2/2-way solenoid directional control valve 4, the rodless cavity of support cylinder 9 is connected with fuel tank 1 by choke valve 10；
The oil-in of one oil-out connection clamping cylinder 6 of two four-way electromagnetic reversing valves 5, the closing of another oil-out, the oil return opening connection fuel tank 1 of two four-way electromagnetic reversing valves 5；
Also including quiet piece 7 clamped by clamping cylinder 6, clamping cylinder 6 is fixedly connected on the both sides of quiet piece 7 by clamping cylinder housing 11 symmetry；
The quiet piece 7 internal hole offering a rectangular shape, being provided with a motion block 8 in hole, motion block 8 one end is and the rectangular structure of described hole Matching installation, and the other end is sector structure, the lateral symmetry of the cuboid end of motion block 8 offers rectangular channel 81, and the sector structure end of motion block 8 connects support cylinder 9；
Being provided with spring 12 and piston 13 in the clamping cylinder housing 11 of clamping cylinder 6, spring 12 is arranged at the side without extension bar of piston 13, rectangular channel 81 corresponding matching stretched out on rod end and motion block 8 of piston 13.
Further, described piston 13 extension bar end is provided with roller 14.By the effect of roller 14, when the extension bar of piston 13 is introduced in rectangular channel 81, motion block 8 is played pressuring action, and it is the most mobile to ensure that motion block 8 can continue to.
Further, described rectangular channel 81 symmetry offers multipair.So that realizing eccentric throw is carried out the adjustment demand of different range.
The operation principle of the eccentric that this exciting force is variable is as follows:
When needs change exciting force; it is positioned at the vertical position shown in Fig. 1 due to action of gravity motion block 8 after equipment downtime; adjust choke valve 10 and be in cut-off state; starting hydraulic system, first 2/2-way solenoid directional control valve 4 and obtain electric, pressure oil enters the rodless cavity of support cylinder 9; support motion block 8; then 2/2-way solenoid directional control valve 4 dead electricity, two four-way electromagnetic reversing valves 5 obtain electric, and pressure oil enters clamping cylinder 6.Adjust choke valve 10 openings of sizes, support cylinder 9 piston rod moves down under motion block 8 action of gravity, when the position at the piston 13 extension bar place in clamping cylinder 6 is positioned on the outer wall of motion block 8, and during not corresponding with rectangular channel 81 clamping, two four-way electromagnetic reversing valve 5 dead electricity, the roller 14 on piston 13 extension bar end in clamping cylinder 6 is pressed in motion block 8 both sides under spring 12 acts on, owing to the effect of roller 14 makes frictional force the least, motion block 8 continues to glide, when moving down into rectangular channel 81 and coming downwards to piston 13 external part, piston 13 end enters rectangular channel 81, motion block 8 is clamped.Now moving down due to motion block 8, the barycenter of motion block 8 and quiet piece 7 device constituted strengthens with center of rotation distance, i.e. eccentric throw increases, thus changes exciting force.Adjusting complete, two bar oil pipes joining with clamping cylinder 6 are pulled down, and block the oil-in of clamping cylinder 6 with screw plug simultaneously.When needs reduce exciting force, by above-mentioned steps, by the effect of hydraulic system and support cylinder 9 by motion block 8 fight back quiet piece 7.
In sum, the variable eccentric of this exciting force utilizes the overhanging of motion block or inside contracts the eccentric throw changing eccentric, thus change the size of exciting force, achieve without changing eccentric block, and can automatically change the effect of exciting force size, structure is ingenious, easy to operate, it is easy to safeguard, there is wide applicability.
