Description
Technical field
The utility model relates to a kind of air-expanding shaft, particularly relates to a kind of air heave type mechanical clamping head.
Background technology
Current, in papermaking, plastics, in the industries such as printing, be all generally air-expanding shaft for propping up the fix shaft of bobbin, existing air-expanding shaft structure is mainly by air bag component, expansion block assembly, the formations such as hollow axis body assembly, expansion block assembly comprises expansion block, spring leaf, interior swollen plate, expansion block is strip derby, adopt screw to be contained on interior swollen plate, its shortcoming is easy gas leakage, once gas leaks in air bag component, expansion block assembly may shrink moment, the meetings such as paper or plastics and bobbin come off because of the Action of Gravity Field of himself, bring loss to production, the safety that also can endanger operating personal when serious.
Summary of the invention
The purpose of this utility model is to provide a kind of air heave type mechanical clamping head, solves the easily technological deficiency of gas leakage of air-expanding shaft in prior art.
For addressing the above problem, technical solution adopted in the utility model is:
A kind of air heave type mechanical clamping head, comprises
Dop seat, described dop seat has the first through hole vertically, the first described through hole cross section diameter T-shaped and left end is less than the diameter of right-hand member, on the left end outer wall of described dop seat, have above first groove communicating with the first through hole, on the sidewall of dop seat right-hand member, have more than one induction opening;
Mandrel, described mandrel left end is round table-like, it is cylindric that right-hand member is, its left end end axis, to having the first blind hole, arranges the first stage clip in the first described blind hole, and described mandrel is arranged in the first through hole, the right-hand member of mandrel arranges piston, the equal diameters of the external diameter of piston and the first through hole right-hand member;
With the dop slide block that mandrel attracts each other, described dop slide block is arranged in the first groove, and the face that dop slide block contacts with mandrel is the curved surface matching with the round platform of mandrel left end;
Plug, described plug is arranged on the left end of dop seat, and the left end of the first described stage clip props up plug.
The utility model moves in dop seat by gas push mandrel and piston entirety, because mandrel is the curved surface matching with dop slide block contact position, ensure that dop slide block radial direction along dop seat in the first groove is simultaneously outwards mobile, dop slide block away from the face of mandrel all the time in horizontality, it is more firm to propping up of bobbin to keep, while putting down bobbin, only need to discharge the gas passing into above, stage clip extends promotion mandrel and piston is got back to original position, because dop slide block and mandrel can attract each other, so dop slide block is close to mandrel all the time, be that dop slide block shrinks in the first through hole of dop seat, the utility model does not have air bag component, therefore there is not the phenomenon of air bag component gas leakage, even if there is gas leakage in the junction of dop seat and accumulator unit, stage clip promotion mandrel moves right and also needs the regular hour, dop slide block can just not be retracted to original state immediately.
As further improvement of the utility model, the left end cover of described dop slide block has anchor plate, the equal diameters of the external diameter of anchor plate and the first through hole left end.
Anchor plate is set, and is that the movement of mandrel in the first through hole is the axis direction along dop seat all the time, can not be offset, and makes the synchronism of each dop slide block better, is also beneficial to the movement in the first through hole of mandrel and piston.
As further improvement of the utility model, on described piston, seal ring is set.
Seal ring is set, and the better tightness of piston and the first through hole, prevents that gas from entering the left side of piston, makes the pressure in piston left side become large, then promotes piston and the larger power of mandrel needs.
As further improvement of the utility model, described piston comprises first piston and the second piston, the diameter of described first piston left end is greater than the diameter of right-hand member, described seal ring is enclosed within the right-hand member of first piston, the second described piston is fixed on the diameter that the right side of first piston and its diameter are greater than first piston right-hand member, and described seal ring is stuck between first piston and the second piston.
Seal ring will move together with piston, if piston is made of one formula, to firmly seal ring be pushed away on piston, it is enclosed within on piston, easily damage seal ring by brute force, destroy the sealing property of seal ring, piston is divided into first piston and the second piston by the application, first by seal ring set on first piston, and then the second piston and first piston are fixed, block seal ring, it can not be come off, due to by seal ring set on first piston, be hold facile, can not damage seal ring yet, so the utility model easily installs seal ring, protect again seal ring, improve its service life.
As further improvement of the utility model, the first described groove has four, is evenly distributed on the outer circumference surface of dop seat left end.
Four the first grooves evenly arrange, and dop slide block is set in it, are that the axis of its bobbin propping up and the axis of dop seat are consistent, and are convenient to the follow-up processing to paper or plastics.
As further improvement of the utility model, also comprise
Overcoat, described overcoat axially has the second through hole, the equal diameters of the diameter of the second described through hole and dop seat left end, described outer second groove corresponding with the first groove that put;
Overcoat slide block, on described overcoat slide block, the horizontal waist-shaped hole that has, also has second blind hole on overcoat slide block, and described the second blind hole and waist-shaped hole are cross-shaped;
Flange pin, described flange pin, through the waist-shaped hole on overcoat slide block, is arranged on overcoat slide block in the second groove;
The second stage clip, the second described stage clip is arranged in the second blind hole and the two ends of the second stage clip prop up respectively cecum and the flange pin of the second blind hole.
In the time that the bobbin internal diameter propping up is larger, overcoat is enclosed within on dop seat, and overcoat slide block is relative with dop slide block, dop slide block, to radially outward moving along dop seat, promotes overcoat slide block and moves towards the direction identical with dop slide block, prop up bobbin, now the second stage clip in the second blind hole is compressed, and when dop slide block shrinks not in the time propping up overcoat slide block in dop seat, stage clip extends the compression state before that returns to, shift overcoat slide block onto original state, and no longer prop up bobbin; Owing to having increased overcoat, so the utility model class props up the bobbin that internal diameter is larger, prop up the bobbin that internal diameter is less, only need take off overcoat.
As further improvement of the utility model, the right-hand member of overcoat is provided with locating dowel pin, the corresponding knock hole that arranges on dop seat.
With locating dowel pin and knock hole externally cover position, be convenient to right should the installing of overcoat slide block and dop slide block, improve the speed of overcoat installation, thereby improve overall work efficiency.
Further improve as of the present utility model, the right-hand member of described overcoat radially has fixed orifice.
Fixed orifice is set, the fixed jackets such as bolt and dop seat can be set in fixed orifice, prevent from coming off at dop slide block overcoat in outwards mobile process, or overcoat be owing to relatively rotating around dop seat after being moved to the left, cause the dop slide block can not be just to overcoat slide block, thus propping up unsuccessfully of causing.
In sum, the beneficial effects of the utility model are: do not use air bag component, so there is not the defect of gas leakage; Can meet propping up of the bobbin less to internal diameter, have and can prop up the larger bobbin of internal diameter, and the utility model be simple in structure, easy to operate.
