Abstract
The utility model provides a cylinder internal stay presss from both sides tight frock belongs to the frock clamp field, including fixing anchor clamps base and the anchor clamps end cover of fixed mounting on the anchor clamps base on the lathe headstock, be provided with the outer cone pole in the anchor clamps end cover, outer push rod right -hand member is provided with the male cone (strobilus masculinus), still is provided with the internal stay cover that rises in the anchor clamps end cover, and the internal stay rises by set right -hand member and is provided with the interior conical surface, and the outer cone combined with of the conical surface and outer push rod in should, internal stay rise by the left end of cover and connect the pull rod through connecting the fork, and pull rod connection pneumatic cylinder, internal stay rise by set right -hand member and stretch out outside the anchor clamps end cover. The utility model provides a cylinder internal stay presss from both sides tight frock presss from both sides tightly the work piece through taper fit's mode, has guaranteed the axiality of clamping between work piece and the frock, this frock only need be equipped with different internal stays according to the work piece of process and rise by the cover and just can satisfy the processing of each model, and the taper fit precision is high, and the internal stay rises and set changes simply, processes each NULL ability reinforce, long service life to the work piece.
Description
Technical field
The utility model relates to a kind of cylinder inner support clamping tool, belongs to frock clamp field.
Background technology
The existing frock clamp adding man-hour for cylinder, oil pressure 8 cun of chuck stiffened three-jaws are used to carry out clamping to cylinder part, car is to needs size, during processing work (cylinder part) external diameter, hard three-jaw outwards now opens clamping work pieces internal diameter, because effect only has radial opening force, after clamping workpiece, axial width can not be ensured;
Oil pressure chuck needs per tour maintenance to beat lubricating grease, and the life-span only has 6-8 month, and main manifestations is that in chuck, claw and chuck body wear and tear post gap greatly, thus precision reduces, and can not ensure the axiality of clamping between workpiece and fixture;
Claw manufacturing cost is high, joins car and requires for employee high to needs size.Need outfit how secondary when type is different, and need to join car after each clamping, cause the life-span low.
Utility model content
The purpose of this utility model is to provide a kind of cylinder inner support clamping tool, to solve the problems of the technologies described above.
Technical problem to be solved in the utility model realizes by the following technical solutions:
A kind of cylinder inner support clamping tool, it is characterized in that: comprise the clamp base be fixed on lathe headstock and the fixture end cap be fixedly mounted in clamp base, outer cone bar is provided with in described fixture end cap, outer push rod right-hand member is provided with male cone (strobilus masculinus), inner support ringfeder is also provided with in described fixture end cap, inner support ringfeder right-hand member is provided with inner conical surface, this inner conical surface coordinates with the male cone (strobilus masculinus) of outer push rod, the left end of described inner support ringfeder is by yoke cylinder lever connecting rod, pull bar connecting fluid cylinder pressure, described inner support ringfeder right-hand member stretches out outside fixture end cap.
The centre, right side of described fixture end cap offers circular centre bore, and described inner support ringfeder right-hand member stretches out in this centre bore.
The stage casing of described inner support ringfeder is cylindrical, and right section is inner support tensioner section, and left section is the flange for connecting yoke.
Described inner support ringfeder has hollow cavity, and right section of this hollow cavity has inner conical surface, and outer cone bar inserts in this hollow cavity, coordinates with inner conical surface.
Operation principle: hydraulic cylinder (lathe oil cylinder) action backward, pull pull bar, pull bar pulls yoke, yoke pulls (namely shown in the figure left) action backward of inner support ringfeder, outer cone bar will insert position darker in inner support ringfeder, the inner conical surface of inner support ringfeder coordinates with the male cone (strobilus masculinus) of outer cone bar, under the effect of push rod outside, inner support ringfeder right-hand member can outside spreading, workpiece (cylinder part) to be processed is enclosed within the right-hand member of inner support ringfeder, thus by the internal diameter tensioner of workpiece, in process due to the outside tensioner of inner support ringfeder, to the active force of workpiece backward, make while clamping work pieces workpiece backward action to fixture end cap, ensure the axial two sides depth of parallelism and thickness, tensioner is realized by the conical surface, taper fit ensure that the axiality of clamping between workpiece and fixture.
This fixture only needs the processing that just can meet each type according to processed workpiece diameter for different inner support ringfeders, and taper fit precision is high, strong for work pieces process each accuracy guarantee ability;
Price is the same with claw, but each replacing just can ensure precision after loading, and can use for a long time, saves replacing construction, adds the long life.
The beneficial effects of the utility model are:
The cylinder inner support clamping tool that the utility model provides, is clamped workpiece by the mode of taper fit, ensure that the axiality of clamping between workpiece and frock; This frock only needs the processing that just can meet each type according to processed workpiece for different inner support ringfeders, and taper fit precision is high, and inner support ringfeder is changed simple, strong for each accuracy guarantee ability of work pieces process, long service life.
