Description
Technical field
The present invention relates to a kind of clamping locking device, especially relate to one and hold cylinder tightly.
Background technique
At present, common cylinder on market, as Chinese patent notice of authorization number: CN202646224U, January 2 2013 notice of authorization day, a kind of cylinder is disclosed, comprise front cover, cylinder barrel, piston rod, piston, rear end cover, between piston and cylinder barrel, be provided with seal ring one, seal ring one is located on piston, between front cover and cylinder barrel, be provided with seal ring two, seal ring two is located on described front cover, between piston rod and described piston, be provided with seal ring three, seal ring three is located on described piston, between cylinder barrel and described rear end cover, be provided with seal ring four, seal ring four is located on described rear end cover.Such cylinder is to utilize position control valve to make cylinder piston two ends keep balance pressure to reach the effect that precalculated position stops substantially, but due to the compressibility of air, is difficult to correctly stop accurately.Owing to can not ensureing zero air leakage of valve and cylinder, therefore can not stop on precalculated position for a long time, and when dying suddenly in cylinder operation loop, when power-off, locating effect lost efficacy at once, had larger potential safety hazard.
Summary of the invention
In order to overcome the above-mentioned deficiency of prior art, the invention provides a kind of can realization and accurately stop, can keeping stopping at for a long time on precalculated position and can effectively clamp the cylinder of holding tightly of locking when dying suddenly in cylinder operation loop, when power-off.
To achieve these goals, the present invention is by the following technical solutions:
One of the present invention is held cylinder tightly, comprise body, in described body, be provided with two holding sheets that are vertically arranged symmetrically with and for holding the inner chamber of holding sheet, the lower end of described holding sheet offsets and can relatively rotate, each holding sheet upper end is respectively equipped with can be by the inwardly locking spring of extruding of holding sheet, described holding sheet top is provided with piston, the lower surface of piston is provided with the release projection that two holding sheets outwards can be strutted, also comprise the slide bar that runs through body and holding sheet, described holding sheet is provided with the positioning hole matching with slide bar, when described holding sheet is vertical with slide bar, between slide bar side and positioning hole inwall, in the vertical direction is provided with clamping gap.When piston is positioned at the top dead center of its stroke, holding sheet is under the effect of locking spring, and taking holding sheet lower end, as rotating the inside deflection of basic point, the axis of positioning hole and slide bar axis also deflect, thereby by slide bar clamping locking; In the time having External Force Acting in piston, release projection on piston overcomes the spring force of locking spring for the active force of holding sheet, thereby holding sheet is pushed open to both sides, the axis of positioning hole and slide bar dead in line, the locking state of removing slide bar, slide bar relatively holding sheet is free to slide.The external force that acts on piston can be air pressure, oil pressure, can be also manpower manual release.In the time that external force disappears, can realize locking, thereby correctly stop accurately, and can ensure that slide bar is for a long time in locking state.When dying, when power-off, can automatically realize at once locking effect, greatly improve Security.In addition, locking spring is positioned at holding sheet upper end for holding sheet as use, and therefore positioning hole can give the coupling mechanism force that slide bar is larger, improves clamping reliability.
As preferably, described release projection comprises the spacing inclined-plane that cross section is the raised line of circular arc and extends from raised line two side direction piston lower surfaces, and described holding sheet upper end is provided with the cambered surface matching with release projection.In the time that piston moves downward, raised line contacts with cambered surface, and enters between two holding sheets, and holding sheet is pushed open to both sides.
As preferably, described holding sheet comprises holding sheet body and is positioned at holding sheet body lower end, the rotation end vertical with holding sheet body, the rotation end of two holding sheets leans, rotate the end rounding off of end, described holding sheet body is provided with step locating face, the positioning step matching with step locating face in the bottom of described inner chamber at the opposite side that rotates end.Coordinate holding sheet is positioned by step locating face and positioning step, after holding sheet is unlocked projection and struts, can be positioned at vertical position, ensure the smooth and easy slip between slide bar and holding sheet.
As preferably, the internal chamber wall of described inner chamber is rounded, and two vertical opposite flanks of described holding sheet are the arc release locating face matching with internal chamber wall.Piston decline time, holding sheet contacts and is adjacent to the internal chamber wall of body, holding sheet is carried out spacing, thereby piston is played to position-limiting action, piston reaches lower dead center.
As preferably, described body both sides are respectively equipped with the adjustment hole for holding locking spring, are provided with the adjusting bolt for positioning and locking spring in described adjustment hole.By adjusting the degree of depth that is screwed into of adjusting bolt, can adjust the size of locking spring to holding sheet extruding force, thereby realize the adjusting of chucking power, be convenient to debug.In addition, after wearing and tearing appear in positioning hole, also can adjust locking spring, make holding sheet and slide bar keep reliably contacting.
As preferably, described positioning hole is respectively equipped with interior chamfering and the outer chamfering that angle is consistent in the both sides of holding sheet, and the upper end of described interior chamfer surface and the lower end of outer chamfer surface are being less than the diameter of slide bar perpendicular to the distance in inside and outside chamfer surface direction.After holding sheet deflection, positioning hole can produce enough chucking powers to slide bar like this, improves with contacting of slide bar simultaneously and avoids stress to concentrate, and ensures the reliable clamping locking for slide bar.
As preferably, also comprise end cap, described piston is arranged in end cap, and the center of end cap is provided with through hole, and the lower end of through hole extends to form positive stop lug boss downwards, and described piston upper surface is provided with the countersunk head circular groove matching with positive stop lug boss.Limit the top dead center of piston by positive stop lug boss, in through hole, can pass into oil pressure or air pressure, control holding sheet in locking or released state thereby piston is moved up and down.
As preferably, described through hole is tapped hole, in described through hole, is provided with release screw bolt.Can realize manual releasing locking state by being manually screwed into release screw bolt, comparatively convenient.
Therefore, the present invention has following beneficial effect: (1) can clamp locking to slide bar by holding sheet, and accurate positioning is quick; (2) slide bar, in the time of locking state, can cannot not stop at precalculated position because of the erratic fluctuations of air pressure, oil pressure; (3) when dying, when power-off, holding sheet can, to slide bar auto lock, be avoided meeting accident, Security is largely increased; (4) chucking power of holding sheet is adjustable, and adaptability is higher, ensures that holding sheet is reliably connected with slide bar; (5) can or manually be screwed into release screw bolt by air pressure, oil pressure and complete release, Applicable scope is wider, and operation more for convenience.
