Ring flange etc. is formed.There is the flat boss of milling one end of described rotary sliding pull bar, and there are helicitic texture, milling in the outer end of the flat boss of milling
There are spring washer, nut outside for assembling quick change pressing plate, quick change pressing plate on flat boss, compressed jointly with the helicitic texture at the flat boss end of milling fast
Change pressing plate；The other end of described rotary sliding pull bar leaves circular bosses, for two sets of thrust ball bearings of assembling on circular bosses, two
There is helicitic texture for assembling pulling plate, the outer end of circular bosses between thrust ball bearing, for compressing thrust ball bearing and drawing using nut
Disk；Described pulling plate is to be mutually 120 degree of Y-shaped structure, each component on described rotary sliding pull bar and pull bar, passes through one end
Assembled with pulling plate, the other end coordinates with the slip bushing inlayed on clamp body and clamp body, has a spiral shell on rotary sliding pull bar
Spin slot, there is guide finger in helicla flute, guide finger runs through clamp body and slip bushing, is fixed on by the helicitic texture on clamp body
On clamp body and the spiral trench bottom that directes reach on rotary sliding pull bar, 0.5-1mm gaps are reserved with bottom surface.In described pulling plate
Between a circular hole is set, hydraulic connecting bar is provided with circular hole, there is step described hydraulic connecting bar one end and between pulling plate endoporus
There is helicitic texture the cylinder that gap coordinates, the cylinder outer end, are combined with double nut and compress pulling plate, pulling plate and hydraulic connecting bar platform
Rank reserves 0.5mm gaps；The described hydraulic connecting bar other end has helicitic texture, is connected with hydraulic cylinder, hydraulic connecting bar is cylindrical
On be provided with the positioning and guiding set of gap cooperation, to ensure hydraulic connecting bar under hydraulic cylinder effect, during axial movement and lathe
The concentricity of main shaft；Described positioning and guiding set is anchored on the bottom plate of clamp body.Described clamp body uses to mitigate weight
Weldment simultaneously carries out Ageing Treatment, and this clamp body includes panel, bottom plate and connection column, couple after each part difference roughing,
Assemble, finished after firm welding, abundant timeliness, to ensure each size and form and position tolerance.Described clamp body one end is equipped with quilt
The positioning body of part is processed, the other end is anchored on the ring flange being connected with machine tool chief axis.
Described rotary sliding pull bar is three, and quick change pressing plate is three, and the guide finger being placed in helicla flute is three.
There is a helicla flute on described rotary sliding pull bar, the width of helicla flute is 8-10mm, depth 6-8mm, is revolved
Gyration is 30-60 degree.
Non-circular hole is provided with described quick change pressing plate, is combined with the flat boss of milling of rotary sliding pull bar one end.
Described thrust ball bearing is two sets on each rotary sliding pull bar.
Described clamp body is Combination Welding part, comprising six clamp body panel, clamp body bottom plate, connection, column, is needed
Finished after abundant timeliness.
Described hydraulic connecting bar, positioning and guiding set, pulling plate are each one.
Described hydraulic connecting bar, which is alternatively, is pneumatically connected bar.
Described pulling plate is to be mutually 120 degree of Y-shaped structure, and pulling plate is provided centrally with circular hole.
Beneficial effects of the present invention：The present invention is reasonable in design, is not exchanged excessively by parts to be processed size substantially
Clamp part, if accessory size great disparity is excessive, only adjust quick change pressing plate.The structure because employing rotary sliding pull bar,
So that handling part is quick and easy, while also it is substantially reduced integral clamp volume, weight is effectively controlled, to lathe master
Axle quality stability plays a very good protection；Two sets of thrust ball bearings are used on the structure rotary sliding pull bar, use spiral shell
Mother compresses pulling plate by thrust ball bearing so that rotary sliding pull bar changes nut, sliding tie rod end face in rotary course
Force of sliding friction with pulling plate end face is force of rolling friction, reduces the abrasion between part；Simultaneously because of the work of double set thrust ball bearings
With, nut can be killed pulling plate by bearing, while under the positioning and guiding set effect being anchored on clamp body bottom plate, to ensure
Hydraulic connecting bar when external force moves axially and machine tool chief axis concentricity；Under above-mentioned double action so that 3 rotatable cunnings
When dynamic pull bar moves axially under the external force effect of hydraulic connecting bar, its direction of motion is parallel to each other, reduces and is rubbed in slipping
Power is wiped, reduces the abrasion between part.
Brief description of the drawings
Fig. 1 is the structural representation of the present invention.
In Fig. 1：1- hydraulic connecting bars, 2- pulling plates, 3- thrust ball bearings A, 4- thrust ball bearing B, 5- rotary sliding are drawn
Bar, 6- guide fingers, 7- quick change pressing plates, 8- slip bushings, 9- clamp bodies, 10- positioning and guiding sets, 11- ring flanges.
Embodiment
The present invention is described further below in conjunction with the accompanying drawings.
Embodiment 1
As shown in figure 1, the present invention is when implementing：Hydraulic connecting bar 1 is being anchored on fixture vertically under hydraulic cylinder effect
Moved to left on body 9 under the auxiliary of positioning and guiding set 10, pull pulling plate 2 to move to left simultaneously, pulling plate 2 can drive three rotary sliding pull bars 5
Move to left simultaneously, during rotary sliding pull bar 5 moves to left, in the presence of guide finger 6, the edge with the axial displacement of helicla flute
Its central rotation, drive the quick change pressing plate 7 for being anchored on end while rotate, when the rotation of rotary sliding pull bar 5 terminates complete edge
When its axis moves to left, quick change pressing plate 7 will compress part to be processed, then persistently move to left, that is, compress part to be processed, each for processing
