Specific embodiment
The utility model is described in detail with reference to the accompanying drawing.
As shown in Figure 1, a kind of the two poles of the earth regulating device of Multi-cylinder buffer synchronisation, including oil cylinder ontology and external speed regulation dress
It sets, external speed regulation device is installed on oil cylinder ontology, for adjusting the buffer speed of oil cylinder in real time, realizes that Multi-cylinder buffering is same
Step, oil cylinder ontology is interior to be arranged piston rod 1 and piston 2, is equipped with dashpot 7 inside the cylinder bottom 6 of oil cylinder ontology, is used for buffer plunger 4
Disengaging, buffer plunger 4 are fixed together by the circlip 3 of rear end with 1 head of piston rod, and there is larger chamfering in 4 front end of buffer plunger
And there is milling face on the whole body, 4 Leading end chamfer of buffer plunger is 15-20 °, and piston rod 1 passes through piston 2 and back and forth stretched out or retracted,
Buffer plunger 4 is driven to pass in and out dashpot 7, external speed regulation device includes throttling plunger 9, fixing seat 10, adjustable column 11 and speed regulation rotation
Button 12, external speed regulation device are installed on the cylinder bottom 6 of oil cylinder ontology, the cylinder bottom of oil cylinder ontology by being screwed in fixing seat 10
Throttling channel 8 and oil duct are increased on 6, oil duct includes the upper oil duct 5 being connected and is contained with hydraulic oil inside right oil duct 13 and the two,
Hydraulic oil in right oil duct 13 can be flowed out by upper oil duct 5, install throttling plunger 9 additional in throttling channel 8, and throttling plunger 9 is cylinder
There is bigger chamfering on body machined piece, head, and chamfering is 15-20 °, and convenient for control hydraulic fluid flow rate, throttling plunger 9 passes through
Adjustable column 11 is connected to outside cylinder bottom 6, and throttling plunger 9 stretches out cylinder bottom 6 and backwards to the tail end on throttling 9 head of plunger equipped with speed regulation rotation
Button 12 is moved up or down by adjusting the speed the precession of knob 12 or screwing out control throttling plunger 9, for adjusting the buffering of oil cylinder
Speed, throttling 9 head chamfered region of plunger can pass in and out right oil duct 13, for adjusting the hydraulic fluid flow rate in right oil duct 13, and then adjust
The buffer speed of fuel-economizing cylinder.
Knob 12 is adjusted the speed when original state and is adjusted to minimum, that is, is screwed to bottom, and throttling plunger 9 blocks oil duct, cylinder buffer completely
When hydraulic oil enter dashpot 7 and throttling channel 8 simultaneously, gap between buffer plunger 4 and dashpot 7, throttling plunger 9 and section
The lower realization buffering effect of gap throttling between chute 8 passes through clockwise or counter-rotating cylinder bottom when two oil cylinders are asynchronous
Speed regulation knob 12 outside 6 is the buffer speed that can control the oil cylinder, achievees the purpose that two-tank method buffers with this；If oil cylinder is not
When needing to buffer, speed regulation knob 12 can be adjusted to maximum, throttling pillar plug 9 is made to completely disengage oil duct, no buffering can be realized in oil cylinder,
The switching between cushion cylinder and non-buffered oil cylinder can be achieved, meet oil cylinder various working demand.
The working principle of the utility model are as follows:
When piston rod 1 retracts, buffer plunger 4 is progressed into dashpot 7, between buffer plunger 4 and dashpot 7
Gap be gradually reduced, hydraulic oil is flowed out from the gap via upper oil duct 5, meanwhile, into right oil duct 13 hydraulic oil through throttling
Gap between slot 8 and throttling plunger 9 is also flowed out by upper oil duct 5, and 1 movement velocity of piston rod slows down, and buffering works, to be buffered
After plunger 4 is completely into the dashpot 7 in cylinder bottom 6, buffering terminates, 6 end of 1 head of piston rod and cylinder bottom when avoiding stroke terminal
The shock in face.
If two or oil cylinder occur retracting asynchronous during retraction, the slower oil cylinder of buffer speed may be selected, it will
The speed regulation knob 12 of its external external speed regulation device slowly screws out, and throttling plunger 9 moves down, 9 head chamfered region of plunger to be throttled
After domain enters right oil duct 13, the hydraulic fluid flow rate in oil duct increases, and buffer speed is accelerated, essentially identical to two oil cylinder speed
When, i.e. completion cushion cylinder synchronism fine tuning；Two occur during retraction with upper oil cylinder retract it is asynchronous when, use is aforementioned
Speed regulation step identical with two oil cylinders.
The above is only the preferred embodiment of the utility model, it should be pointed out that: for the common skill of the art
For art personnel, without departing from the principle of this utility model, several improvements and modifications can also be made, these improve and
Retouching also should be regarded as the protection scope of the utility model.
