Abstract
The invention discloses a hydraulic buffer limiting assembly. The hydraulic buffer limiting assembly is characterized by comprising a hydraulic ring and a control rod assembly, a rotary shaft and a separation board are arranged in the hydraulic ring, the interior of the hydraulic ring is divided into a cavity and an oil cavity through the separation board, and a matching groove is formed in the hydraulic ring; the control rod assembly comprises a control rod, a hydraulic box and a hydraulic arm; the hydraulic box is arranged in the cavity, the hydraulic arm is arranged in the oil cavity, the hydraulic box and the hydraulic arm are connected into a whole through a connecting piece, and the connecting piece is rotationally arranged on the rotary shaft; the control rod penetrates the matching groove to be matched with the hydraulic box; and the inner wall of the oil cavity is provided with two stroke stop blocks. By the adoption of the hydraulic buffer limiting assembly, the rotation action of the control rod is buffered through the hydraulic arm, the pressing action of the control rod is buffered through the hydraulic box, the buffering effect is good, no noise is generated, abrasion is small, and the service life is long; and the two stroke stop blocks serve as two rotation end points of the hydraulic arm to limit rotation of the control rod.
Description
Technical field
The present invention relates to a kind of hydraulic cushion limit assembly.
Background technique
On the production line of semi-automation, need manually to be controlled machine operation by controlling rod, controlling rod is when carrying out control gearshift, if exerted oneself, conference produced and clashed into, cause controlling rod to wear and tear, for the parts that this frequency of utilization of controlling rod is high, the rate of wear quickly; And the existing buffer structure also devising some controlling rods for this situation, as the elastic component of spring and so on, but the wearing and tearing of controlling rod have been transferred to the wearing and tearing to buffer unit by the buffer structure of machinery, need to carry out frequent replacing to buffer unit, bother very much, and buffer unit service time slightly length will produce very large noise, it is very inconvenient to use.
Summary of the invention
For the technical problem of above-mentioned existence, the object of the invention is: propose a kind of hydraulic cushion limit assembly.
Technical solution of the present invention is achieved in that a kind of hydraulic cushion limit assembly, it is characterized in that: comprise hydraulic pressure ring and controlling rod assembly, rotating shaft and the demarcation strip through rotating shaft is provided with in hydraulic pressure ring, the inside of hydraulic pressure ring is divided into cavity and oil pocket by demarcation strip, and the ring wall of hydraulic pressure ring has mating groove on the side of cavity; Described controlling rod assembly comprises controlling rod, hydraulic pressure box and hydraulic arm; Described hydraulic pressure box is arranged in the cavities, and hydraulic arm is arranged in oil pocket, and hydraulic pressure box and hydraulic arm are connected as a single entity by link, and link rotates and is arranged in rotating shaft; Described controlling rod through mating groove, and coordinates with hydraulic pressure box; The inwall of described oil pocket is provided with two stroke dogs, two stroke dogs rotate terminal as hydraulic arm two.
Preferably, described cavity is semicircle.
Preferably, described oil pocket is semicircle.
Preferably, described mating groove is quadrant arc.
Due to the utilization of technique scheme, the present invention compared with prior art has following advantages:
Hydraulic cushion limit assembly of the present invention, by the setting of hydraulic arm in oil pocket, plays buffer function to the rotational action of controlling rod, and play buffer function by the push action of hydraulic pressure box to controlling rod, buffering effective, and there is no noise, wearing and tearing are few, long service life; Two stroke dogs rotate terminal as hydraulic arm two, play position-limiting action to the rotation of controlling rod.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, technical solution of the present invention is described further:
Accompanying drawing 1 is the schematic diagram of a kind of hydraulic cushion limit assembly of the present invention.
Embodiment
Below in conjunction with accompanying drawing, the present invention is described.
As shown in Figure 1, a kind of hydraulic cushion limit assembly of the present invention, comprise hydraulic pressure ring 1 and controlling rod assembly, rotating shaft and the demarcation strip 2 through rotating shaft is provided with in hydraulic pressure ring 1, the inside of hydraulic pressure ring 1 is divided into cavity and oil pocket by demarcation strip 2, and the ring wall of hydraulic pressure ring 1 has mating groove 3 on the side of cavity; Described controlling rod assembly comprises controlling rod 4, hydraulic pressure box 5 and hydraulic arm 6; Described hydraulic pressure box 5 arranges in the cavities, and hydraulic arm 6 is arranged in oil pocket, and hydraulic pressure box 5 and hydraulic arm 6 are connected as a single entity by link 7, and link 7 rotates and is arranged in rotating shaft; Described controlling rod 4 through mating groove 3, and coordinates with hydraulic pressure box 5; The inwall of described oil pocket is provided with two stroke dogs, 8, two stroke dogs 8 and rotates terminal as hydraulic arm 6 two; Described cavity and oil pocket are semicircle; Described mating groove 3 is in quadrant arc.
When controlling rod 4 is rotated along mating groove 3 by rotating shaft, density oil coordinates with the oilhole on hydraulic arm 6, and hydraulic arm 6 is slowly rotated in oil pocket, and then the controlling rod 4 be connected with hydraulic arm 6 one is cushioned; When controlling rod 4 is pressed or lifting operation time, the density oil in hydraulic pressure box 5 coordinates with the end oilhole of controlling rod 4, cushions the corresponding action of controlling rod 4.
Above-described embodiment is only for illustrating technical conceive of the present invention and feature; its object is to person skilled in the art can be understood content of the present invention and be implemented; can not limit the scope of the invention with this; all equivalences done according to Spirit Essence of the present invention change or modify, and all should be encompassed in protection scope of the present invention.
