A kind of hydraulic cushion guidance set
Technical field
The present invention relates to a kind of hydraulic cushion guidance sets.
Background technology
On semi-automatic production line, need manually to control machine operation by control-rod, control-rod into
During row control gearshift, if conference of exerting oneself generates shock, control-rod is caused to wear, it is high for this frequency of use of control-rod
Component, the rate of wear is very fast;And the buffer structure of some control-rods is now also devised for such case, such as spring etc
Elastic component, but the abrasion of control-rod has been transferred to abrasion to buffer unit by the buffer structure of machinery, is needed to buffer part
Part carries out frequent replacement, very troublesome, and buffer unit usage time slightly length will generate very big noise, using very not
Just.
Invention content
For above-mentioned technical problem, the purpose of the present invention is:Propose a kind of hydraulic cushion guidance set.
What the technical solution of the present invention was realized in:A kind of hydraulic cushion guidance set, includes hydraulic pressure ring and control
Bar assembly processed, is provided with shaft and the demarcation strip across shaft in hydraulic pressure ring, demarcation strip by the inside of hydraulic pressure ring be divided into cavity and
Oil pocket, the ring wall of hydraulic pressure ring are provided with mating groove on the side of cavity;The control bar assembly includes control-rod, hydraulic pressure box and liquid
Pressure arm;In the cavities, hydraulic arm is arranged in oil pocket, and hydraulic pressure box is linked as one with hydraulic arm by connector for the hydraulic pressure box setting
Body, connector are rotatably arranged in shaft;The control-rod passes through mating groove, and coordinates with hydraulic pressure box;It is set in the cavity
There is the guide groove of arc, guide groove is concentric with shaft, and hydraulic pressure box is slidably matched with guide groove.
Preferably, the cavity is semicircle.
Preferably, the oil pocket is semicircle.
Preferably, the mating groove is in quadrant arc.
Due to the utilization of above-mentioned technical proposal, the present invention has following advantages compared with prior art:
The hydraulic cushion guidance set of the present invention, by setting of the hydraulic arm in oil pocket, to the rotational action of control-rod
Cushioning effect is played, and passes through hydraulic pressure box and cushioning effect is played to the push action of control-rod, the effect of buffering is good, and does not have
Noise, abrasion is few, and service life is long;Hydraulic pressure box is slided along guide groove, improves the stability of control-rod rotation.
Description of the drawings
Technical solution of the present invention is described further below in conjunction with the accompanying drawings:
Schematic diagram of the attached drawing 1 for a kind of hydraulic cushion guidance set of the present invention.
Specific embodiment
Illustrate the present invention below in conjunction with the accompanying drawings.
As shown in Figure 1, a kind of hydraulic cushion guidance set of the present invention, includes hydraulic pressure ring 1 and control bar assembly, liquid
Shaft and the demarcation strip 2 across shaft are provided in pressure ring 1, the inside of hydraulic pressure ring 1 is divided into cavity and oil pocket, liquid by demarcation strip 2
The ring wall of pressure ring 1 is provided with mating groove 3 on the side of cavity;The control bar assembly includes control-rod 4, hydraulic pressure box 5 and hydraulic pressure
Arm 6;The hydraulic pressure box 5 is set in the cavities, and hydraulic arm 6 is arranged in oil pocket, and hydraulic pressure box 5 is connected with hydraulic arm 6 by connector 7
It is integrated, connector 7 is rotatably arranged in shaft;The control-rod 4 passes through mating groove 3, and coordinates with hydraulic pressure box 5;The sky
The guide groove 9 of arc is provided in chamber, guide groove 9 and shaft are concentric, and hydraulic pressure box 5 is slidably matched with guide groove 9;The cavity with
Oil pocket is semicircle;The mating groove 3 is in quadrant arc.
When control-rod 4 is rotated by shaft along mating groove 3, density oil coordinates with the oilhole on hydraulic arm 6, makes hydraulic arm
6 slowly rotate in oil pocket, and then are buffered the control-rod 4 with 6 integrally connected of hydraulic arm;When control-rod 4 is carried out by
When pressure or promotion operation, density oil and the end oilhole of control-rod 4 in hydraulic pressure box 5 coordinate, to the action accordingly of control-rod 4
Into row buffering.
The above embodiments merely illustrate the technical concept and features of the present invention, and its object is to allow person skilled in the art
Scholar can understand present disclosure and be implemented, and it is not intended to limit the scope of the present invention, all according to the present invention
The equivalent change or modification that Spirit Essence is made should all cover within the scope of the present invention.
