Abstract
The invention discloses a kind of latch oil cylinder device, comprise cylinder block (1), rodless piston (2), check lock lever (3), snap close (4), wedge shape lock dog (5) and first guide shaft (6), described rodless piston (2) and first guide shaft (6) are separately positioned in cylinder block (1), described snap close (4) is arranged on the both sides of first guide shaft (6) bottom, described wedge shape lock dog (5) is arranged on the both sides on first guide shaft (6) top, and described rodless piston (2) and check lock lever (3) are for separating independent setting.A kind of latch oil cylinder device of the present invention, as long as locking of once pressurizeing can be accomplished, just there is no the problem of position excursion, because the working principle of snap close oil cylinder is different from the working principle of general locking cylinder, make traditional hydraulic jack actuator there occurs the change of matter, practical application effect is good.
Description
Technical field
The present invention relates to a kind of latch oil cylinder device.
Background technique
In prior art, oil cylinder is the power unit of hydraulic system, the distance braking locking of cylinder rod is very crucial problem, and under normal circumstances, the locking position of oil cylinder completes by functional parts such as optoelectronic switch, position switch and hydraulic pressure locking-valves, although be widely used, but limited precision, particularly hydraulic pressure locking-valve, can not " 0 " leak, when the backflow of hydraulic pressure locking-valve minor leakage, the position of oil cylinder just drifts about to some extent.
Summary of the invention
The location that the object of this invention is to provide a kind of oil cylinder does not allow the latch oil cylinder device of any position excursion.
The technological scheme that the present invention is adopted for achieving the above object is: a kind of latch oil cylinder device, comprise cylinder block (1), rodless piston (2), check lock lever (3), snap close (4), wedge shape lock dog (5) and first guide shaft (6), described rodless piston (2) and first guide shaft (6) are separately positioned in cylinder block (1), described snap close (4) is arranged on the both sides of first guide shaft (6) bottom, described wedge shape lock dog (5) is arranged on the both sides on first guide shaft (6) top, and described rodless piston (2) and check lock lever (3) are for separating independent setting.
Described cylinder block (1) is provided with the filler opening (A) and oil outlet (B) that are connected with hydraulic station.
A kind of latch oil cylinder device of the present invention, as long as locking of once pressurizeing can be accomplished, just there is no the problem of position excursion, because the working principle of snap close oil cylinder is different from the working principle of general locking cylinder, traditional hydraulic jack actuator is made to there occurs the change of matter, practical application effect is good, in common oil cylinder, piston and piston rod connect as one work, and in snap close oil cylinder of the present invention, piston and piston rod separate to work, so the ingenious locking of energy, and the design of this latch oil cylinder device is unique, safe and reliable, repeatability is high, switch probability is high, maintenance and renewal part simple, configuration is simple, working life extends, the manufacture of snap close brake cylinder device, special hydraulic actuator is made to obtain optimization.
Accompanying drawing explanation
Fig. 1 is the structural representation of a kind of latch oil cylinder device locking of the present invention station state.
Fig. 2 is the structural representation that a kind of latch oil cylinder device of the present invention opens station state.
In figure: 1, cylinder block; 2, rodless piston; 3, check lock lever; 4, snap close; 5, wedge shape lock dog; 6, first guide shaft.
Embodiment
As depicted in figs. 1 and 2, latch oil cylinder device, comprise cylinder block 1, rodless piston 2, check lock lever 3, snap close 4, wedge shape lock dog 5 and first guide shaft 6, rodless piston 2 and first guide shaft 6 are separately positioned in cylinder block 1, snap close 4 is arranged on the both sides of first guide shaft 6 bottom, wedge shape lock dog 5 is arranged on the both sides on first guide shaft 6 top, cylinder block 1 is provided with filler opening A and oil outlet B, filler opening A is connected with middle pressure hydraulic station with oil outlet B, locking and when opening, two hydraulic fluid ports alternately complete oil-feed respectively and go out functional oil, rodless piston 2 and check lock lever 3 are for separating independent setting, when check lock lever 3 enters cylinder block 1, the snap close 4 of snap close oil cylinder is at rodless piston 2, under the effect of first guide shaft 6, check lock lever 3 is pinned, due to the particularity that wedge shape lock dog 5 shape manufactures, as long as rodless piston 2 to locking direction action once, wedge shape lock dog 5 under rodless piston effect, snap close 4 would not move, because wedge shape lock dog applies the self-locking working principle of metallic material friction angle, the gripping principle that snap close applies " claws of a hawk ", as long as make check lock lever reach locked position, oil cylinder would not have the phenomenons such as lax, deviation situation to occur again, and check lock lever is in locking station, when oil cylinder needs to open, rodless piston 2 counteragent, just easily can open the Self-locking angle of wedge shape lock dog 5, first guide shaft 6, snap close 4, oil cylinder is releasing state, and rodless piston is in opening station.
Claims (2)
1. a latch oil cylinder device, it is characterized in that: comprise cylinder block (1), rodless piston (2), check lock lever (3), snap close (4), wedge shape lock dog (5) and first guide shaft (6), described rodless piston (2) and first guide shaft (6) are separately positioned in cylinder block (1), described snap close (4) is arranged on the both sides of first guide shaft (6) bottom, described wedge shape lock dog (5) is arranged on the both sides on first guide shaft (6) top, described rodless piston (2) and check lock lever (3) are for separating independent setting, when check lock lever (3) enters cylinder block (1), the snap close (4) of snap close oil cylinder is in rodless piston (2), under the effect of first guide shaft (6), check lock lever (3) is pinned.
2. a kind of latch oil cylinder device according to claim 1, is characterized in that: described cylinder block (1) is provided with the filler opening (A) and oil outlet (B) that are connected with hydraulic station.
