Description
Technical field
The invention belongs to machine tool fixture fields, and in particular to a kind of centering pressing device can quickly determine workpiece
Position and compression.
Background technique
In the positioning of machining, when involving the need for by inner circle and with shoulder positioning compression, need to position the same of inner circle
When will also be compressed with shoulder.And require to operate multiple positioning and clamping devices in common fixture, cause certain production quasi-
The waste of standby time and labor intensity.
Summary of the invention
The technical problems to be solved by the present invention are: in machine tool fixture, to needing to carry out positioning pressure by inner circle and with shoulder
In tight part, it is respectively necessary for Design Orientation and pressing device, is also required to operate respectively in use to realize positioning and compression, compared with
It is cumbersome.
A kind of centering pressing device, compresses for feeling relieved to workpiece in circumferential clocking of turbine, which sets in the through-hole of bottom plate
It is equipped with pull rod, which has widened end in the part of bottom plate upper end, has on the inside of the both ends open of both-end expansion set and expands
Inclined-plane, and there is the slot that axially extends at both ends open, both-end expansion set is sleeved on the top of pull rod, in pull rod and both-end
Jacking block is installed in the gap of expansion set lower end, which has the inclined-plane cooperated with both-end expansion set lower end inclined-plane；In the soleplate
Cooperate the rotation of limitation pull rod by the axial groove of pin and pull rod；The pull rod bottom plate lower end partially pass through after driver plate according to
It is secondary to be connect with spheric washer and knurled nut；Pull rod is provided with several groups on driver plate to hold down assembly, the packet that holds down assembly
Pressing plate is included, which is rotatably supported, on the outside by jacking up with the hinged mandril of driver plate, to pass through its inside
End compresses workpiece.
It is described hold down assembly by stud pressing plate central region to pressing plate provide support, stud one end with
Bottom plate connection, the kidney slot that the other end passes through pressing plate are connect with nut.
It is set with spring on the stud, is upwarded pressure by washer to pressing plate offer.
Its position is controlled by laterally pushing or pulling on the pressing plate.
The mating area of the driver plate and spheric washer is inclined-plane.
The quantity to hold down assembly is 3 groups or more, is evenly distributed on the same circumference.
Workpiece is covered before compressing and laterally urges the peripheral structure that pressing plate makes its medial end ride over workpiece in both-end expansion set
On, it rotates knurled nut's realization and the synchronous centering of workpiece is compressed.
The utility model has the advantages that can realize simultaneously positioning by single stepping and compress two steps, it is time saving and energy saving.
Detailed description of the invention
Fig. 1 is the oblique view of present invention centering pressing device；
Fig. 2 is the cross-sectional view of present invention centering pressing device；
Fig. 3 is the structural schematic diagram of pull rod；
Fig. 4 is the structural schematic diagram of both-end expansion set.
Specific embodiment
Workpiece 13 just position by unloaded both-end expansion set 2 and is placed on bottom plate 8, and pressing plate 6 is laterally pushed into work
Position forces pull rod 1 and driver plate 9 to move toward one another, when pull rod 1 moves downward, due to pull rod 1 by rotating knurled nut 12
Upper end is matched with the gradient inside 3 outside of jacking block and both-end expansion set 2, can force pull rod 1 and jacking block 3 distending both-end together
Workpiece 13 is felt relieved and is positioned by expansion set 2, both-end expansion set 2；Driver plate 9 moves upwards simultaneously, and driving mandril 7 moves upwards, and pushes up to pressure
The outer end of plate 6 forces 6 inner end workpiece pressing 13 of pressing plate since stud 4 and nut cooperate the point action played.Pass through
Rotating backward knurled nut 12 can unclamp.
Guarantee that pressing plate 6 is kept certain height inner end in zero load by spring 5 and washer 14, it is quickly horizontal convenient for pressing plate 6
To propulsion and pull out.The mating surface of driver plate 9 and spheric washer 11 is the conical surface, and driver plate 9 can have centainly on spheric washer 11
Rotation space, it is ensured that compress four pressing plates 4 pressing force it is identical.Pin 10 can prevent pull rod 1 from rotating.
