Description
Technical field
The utility model relates to the technical field that complex parts utilize blanking inner hole to locate, and is specially a kind of two self-centering cylindrical float clamp mechanism.
Background technology
For the part needed with blanking inner hole location, its internal structure is complicated, and blank dimension is unstable, and common three-jaw clamping is difficult to ensure that card needs the size of processing part, may occur end face depth offset, the situations such as endoporus ellipse is larger.Making three-jaw in operation is more convenient, and cost is low, but actual percent defective is very high, and the frequency of reprocessing is more.Make cost of spoiled goods increase when making part in enormous quantities, reprocess labour intensity large, the quality for product is uncontrollable.
Summary of the invention
In order to solve the problem, the utility model provides a kind of two self-centering cylindrical float clamp mechanism, and it can realize stable position easily, raises the efficiency, and ensures product quality.
Its technical scheme is such: a kind of two self-centering cylindrical float clamp mechanism, it is characterized in that, it comprises base, described base is provided with mandrel middle base, described mandrel middle base arranged outside has annular boss, in described mandrel middle base, bolt is installed, described bolt lower end is threaded positioning core axle, described bolt is set with two-layer positioner, described positioner comprises the cylindrical compression spring and axle sleeve that are set in described bolt, by the activity orientation sheet that top pressure spring is connected with described mandrel middle base, described cylindrical compression spring is arranged in described axle sleeve lower end, described activity orientation sheet is arranged in described axle sleeve upper end, described axle sleeve upper side has annular ramp, described activity orientation sheet one end has the inclined-plane coordinated with described annular ramp, the other end is through described mandrel middle base.
It is further characterized in that, described base lower end is provided with transition connecting disc, described transition connecting disc lower end has through hole, be provided with moveable main shaft in described through hole and draw cap, described main shaft draws cap upper end to connect intermediate plate, described intermediate plate is provided with multiple hook-shaped arm-tie, the described base of described mandrel middle base sidepiece is provided with multiple positioning seat, each described positioning seat is provided with turnover pressing plate by bearing pin, described pressing plate sidepiece is provided with the locating piece coordinated with described hook-shaped arm-tie, and described locating piece is arranged in the hook-shaped groove with described hook-shaped arm-tie;
Dividing plate is provided with between two-layer described positioner;
Every layer of described positioner comprises three described activity orientation sheets be evenly arranged.
After adopting structure of the present utility model, be positioned on the annular boss of mandrel middle base by needing the part of processing, up turn bolt, drive positioning core axle up mobile extruding cylindrical compression spring, cylindrical compression spring promotes axle sleeve and up moves, due to the setting on annular ramp and inclined-plane, promote activity orientation sheet to eject outward, withstand realizing two self-centering location from inside parts, achieve stable position easily, raise the efficiency, ensure product quality.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation.
Detailed description of the invention
As shown in Figure 1, a kind of two self-centering cylindrical float clamp mechanism, it comprises base 1, base 1 is provided with mandrel middle base 2, mandrel middle base 2 arranged outside has annular boss 3, bolt 4 is installed in mandrel middle base 2, bolt 4 lower end is threaded positioning core axle 5, bolt 4 is set with two-layer positioner, dividing plate 6 is provided with between two-layer positioner, play the effect separating two-layer positioner, positioner comprises the cylindrical compression spring 7 and axle sleeve 8 that are set in bolt 4, by the activity orientation sheet 10 that top pressure spring 9 is connected with mandrel middle base 2, cylindrical compression spring 7 is arranged in axle sleeve 8 lower end, activity orientation sheet 10 is arranged in axle sleeve 8 upper end, axle sleeve 8 upper side has annular ramp, activity orientation sheet 10 one end has the inclined-plane coordinated with annular ramp, the other end is through mandrel middle base 2, when axle sleeve 8 up moves, promote activity orientation sheet 10 outwards to strut, activity orientation sheet 10 moving direction is mutually vertical with bolt 4 moving direction, when axle sleeve 8 moves down, under the effect of top pressure spring 9, activity orientation sheet 10 replys position toward inside contracting, every layer of positioner comprises three activity orientation sheets 10 be evenly arranged, location can be realized better by two-layer six activity orientation sheets 10 up and down.
Base 1 lower end is provided with transition connecting disc 11, transition connecting disc 11 lower end has through hole, be provided with moveable main shaft in through hole and draw cap 12, main shaft draws cap 12 lower end to connect hydraulic main shaft, the movement that main shaft draws cap 12 is realized by the flexible of hydraulic main shaft, main shaft draws cap 12 upper end to connect intermediate plate 13, intermediate plate 13 is provided with three hook-shaped arm-ties 14 be evenly arranged, the base 1 of mandrel middle base 2 sidepiece is provided with three positioning seats be evenly arranged 15, each positioning seat 15 is provided with turnover pressing plate 17 by bearing pin 16, pressing plate 17 outside portion is provided with the locating piece 15 coordinated with hook-shaped arm-tie 14, locating piece 15 is arranged in the hook-shaped groove with hook-shaped arm-tie 14, hook-shaped arm-tie 14 moves up and down the upset of band dynamic pressure plate 17, the location realizing part is further fixed.
